Description

【０００１】
【産業上の利用分野】
本発明は、大量に排出されて廃棄処分となる有機性廃棄物を、短期間で確実に減容処理することができる有機性廃棄物の処理方法およびその装置に関する。
【０００２】
【従来の技術】
従来、生ゴミ等の有機性廃棄物の処理にあっては、各所より排出されたものを集積して焼却工場等において焼却処分されることがほとんどであった。しかしながら、この焼却処理は、年々排出される廃棄物の増加に伴って、集積される廃棄物の量は、前記焼却工場においての処分能力を大きく超えて、その処理に十分に対応することができないものであった。
【０００３】
したがって、一部では、機械的に微生物による醗酵分解を利用して処理することが試みられていた。このものは、図２１に示すように、処理槽７０内へ投入部７１から微生物を混入した生ゴミ７２を供給し、処理槽７０内に横架させた撹拌棒７３付きの回転軸７４の回転によって、この生ゴミ７２に撹拌や切り返しを与えて、微生物による醗酵分解を促進させ該生ゴミ７２の消滅を図っていた。
【０００４】
しかしながら、この装置による生ゴミ７２の処理は、撹拌棒７３による該生ゴミ７２の撹拌や切り返し作用が、図２１において領域ａ１〜ａｎに示すように、この撹拌棒７３の回転作用が及ぶ限られた領域内においてのみ生ゴミ７２の撹拌や切り返しが行われるもので、この作用を受けた生ゴミ７２は、またその同じ領域内に停滞することとなって、例えば、ａ１〜ａｎの領域へ万遍なく移動した撹拌混合を、処理槽７０内の全体に対して行うことができないものであった。
【０００５】
また、処理槽７０内に供給される生ゴミ７２は、比較的大きな塊状となったものや、貝殻や畜獣の骨類更には長尺状の植物繊維なども多く混在しているものであるが、撹拌棒７３による該生ゴミ７２の撹拌や切り返し作用だけでは、小さく粉砕することができず、微生物による醗酵分解に多くの時間を要して、十分にその処理能力を得ることができないものであった。また、繊維類は細かく粉砕できないので、微生物による分解がなかなかできなく、更に、この繊維類は回転軸や撹拌棒類にまつわりついて回転軸に支障を来すこともあって、生ゴミ処理に大きな課題を有するものであった。
【０００６】
【発明が解決しようとする課題】
本発明は、前記した問題点を解決するためになされたもので、上部に有機性廃棄物の投入体を設けて該有機性廃棄物を収容する槽本体内の底部付近に、有機性廃棄物を移送する移送手段を設け、槽本体の適所に該槽本体内へ外気を供給する取り入れ手段を設けると共に、槽本体の適所に該槽本体内の排気を行う排気手段を設けて、移送手段は、回転軸へ所定ピッチの送り羽根を周設したスクリューコンベアであって、該送り羽根は、槽本体内の一側の槽壁近傍から他側の槽壁近傍にわたって設けられ、送り羽根の外周縁と前記槽本体の槽壁との間に、前記有機性廃棄物が介在する隙間を形成させることにより、塊状となったものや硬質の物の有機性廃棄物であっても、槽本体を移送する間に細かく粉砕・磨り潰しを行って、微生物による醗酵分解を促進させて、短時間に減容処理を行うことができる有機性廃棄物の処理方法およびその装置を提供することを目的としている。
【０００７】
【課題を解決するための手段】
前記した目的を達成するための本発明の手段は、
槽本体内へ微生物と共に有機性廃棄物を投入して、この槽本体内の底部付近に設けたスクリューコンベアからなる移送手段により、前記有機性廃棄物を前記槽本体内の一側から他側の槽壁へ向かって移送しつつ、前記移送手段と該移送手段が対応した前記槽本体の槽壁との間に介在する固形状の前記有機性廃棄物を前記移送手段の移送によって細かく破砕や磨り潰しを行い、前記移送手段の移送に伴って前記他側の槽壁に達した前記有機性廃棄物を、前記移送手段によって該有機性廃棄物に掛かる移送圧により前記他側の槽壁に沿って前記有機性廃棄物を隆起させ、この隆起後、再び、前記移送手段上へ落下させて前記槽本体内の底部に戻し、再び、前記槽本体内の一側から他側の槽壁へ向かって移送する循環流動運動と、前記微生物による醗酵分解によって前記有機性廃棄物を処理する有機性廃棄物の処理方法にある。
【０００８】
槽本体内へ微生物と共に有機性廃棄物を投入して、この槽本体内の底部付近に設けた軸方向に対して異なる二方向への有機性廃棄物の送り方向をもったスクリューコンベアからなる移送手段により、前記有機性廃棄物を該移送手段の軸方向中間部から前記槽本体内の一側の槽壁と他側の槽壁とへ向かって移送しつつ、前記移送手段と該移送手段が対応した前記槽本体の槽壁との間に介在する固形状の前記有機性廃棄物を前記移送手段の移送によって細かく破砕や磨り潰しを行い、前記移送手段の移送に伴って前記一側の槽壁と前記他側の槽壁に達した前記有機性廃棄物を、前記移送手段によって該有機性廃棄物に掛かる移送圧により前記一側の槽壁と前記他側の槽壁に沿ってそれぞれ前記有機性廃棄物を隆起させ、この隆起後、再び、前記移送手段上へそれぞれ落下させて前記槽本体内の底部に戻し、再び、前記有機性廃棄物を該移送手段の軸方向中間部から前記槽本体内の一側の槽壁と他側の槽壁とへ向かって移送する循環流動運動と、前記微生物による醗酵分解によって前記有機性廃棄物を処理する有機性廃棄物の処理方法にある。
【０００９】
微生物は坦体に付着させて、この坦体と共に有機性廃棄物に混在させる。
【００１０】
槽本体内における他側の槽壁に沿って隆起させた有機性廃棄物は、該有機性廃棄物の隆起位置に設けた均し手段により、前記槽本体内へ分散させる。
【００１１】
そして、
上部に有機性廃棄物の投入体を設けて該有機性廃棄物を収容する槽本体と、この槽本体内の底部付近に設けて前記有機性廃棄物を移送する移送手段と、前記槽本体の適所に設けて該槽本体内へ外気を供給する取り入れ手段と、前記槽本体の適所に設けて該槽本体内の排気を行う排気手段とを備えさせ、
前記移送手段は、回転軸へ所定ピッチの送り羽根を周設したスクリューコンベアであって、この送り羽根は、前記槽本体内の一側の槽壁近傍から他側の槽壁近傍にわたって設けられ、前記送り羽根の外周縁と前記槽本体の槽壁との間に、前記有機性廃棄物が介在する隙間を形成させた有機性廃棄物の処理装置の構成にある。
【００１２】
槽本体内において、移送手段の上方に均し手段を一基または複数基設ける。
【００１３】
移送手段は、複数列で平行状に並設させる。
【００１４】
移送手段における送り羽根は、回転軸に対して有機性廃棄物の送り方向を異ならせて設ける。
【００１５】
有機性廃棄物は、移送手段によって該有機性廃棄物に掛かる移送圧により他側の槽壁に沿って隆起されるものであり、この有機性廃棄物の隆起部に対応させて、前記移送手段に掻き上げ部材を付設させる。
【００１６】
上部に有機性廃棄物の投入体を設けて該有機性廃棄物を収容する槽本体と、この槽本体内の底部付近に設けて前記有機性廃棄物を移送する移送手段と、前記槽本体の適所に設けて、該槽本体内へ外気を供給する取り入れ手段と、前記槽本体の適所に設けて、該槽本体内の排気を行う排気手段とを備えさせ、
前記移送手段は、前記槽本体へ略水平に取り付けた回転軸と、この回転軸へ取り付けた送り羽根と、前記回転軸の一端部に取り付けた駆動手段とを有し、
前記送り羽根は、前記回転軸が回転したとき、前記槽本体の一側部からこの槽本体の他側部へ向かって該槽本体に収容された有機性廃棄物を移送する第一送り羽根と、前記槽本体の他側部からこの槽本体の一側部へ向かって該槽本体に収容された有機性廃棄物を移送する第二送り羽根とからなる有機性廃棄物の処理装置の構成にある。
【００１７】
移送手段における送り羽根は、該送り羽根の回転外周縁部が槽本体の底部に当接し、前記送り羽根の回転外周縁部に弾性を有する摺擦部材を設ける。
【００１８】
【実施例】
次に、本発明に関する有機性廃棄物の処理方法およびその装置の一実施例を図面に基づいて説明する。
図１〜図２および図４〜図７，図１０〜図１３においてＡは、本発明に係る実施例の有機性廃棄物の処理方法を採用した第一の実施例を示す有機性廃棄物の処理装置で、有機性廃棄物ｂを減容化する処理を行うものであり、図１〜図２においては第一の実施例を示す有機性廃棄物の処理装置Ａであって、槽本体１と、移送手段２と、取り入れ手段３と、排気手段４とにより基本的に構成される。
なお、有機性廃棄物ｂは、生ゴミや有機性汚泥などであって、例えば、廃棄される穀類や野菜，果物，種子類，海藻類あるいは、廃棄される魚や鳥，豚，牛などの肉類や骨類更には卵殻や貝殻類等の一般的な有機物で、微生物ｃによる醗酵分解が可能な物質である。
【００１９】
そして、前記した槽本体１は、上部に有機性廃棄物ｂの投入体５を設けて該有機性廃棄物ｂを収容するもので、この有機性廃棄物ｂはあらかじめ微生物ｃ（好気性細菌等）を散布等により混在させてあるもので、必要に応じて、この微生物ｃは、有機性廃棄物ｂと別々に槽本体１内へ投入してもよい。
なお、投入体５は、槽本体１の上部あるいは天部に所定大きさの窓部６を形成させて、この窓部６にヒンジ等により開閉自在となる蓋体７を取り付けてある。
更に、この槽本体１の上部は、必要に応じて、図１および図４に示すように、脱着自在の上覆体８を設けることもあり、この上覆体８を取り外しすれば、槽本体１の内部のメンテナンスや清掃などを容易に行うことができる。
また、槽本体１の底部適所には、減容処理を終えて残存した処理物を排出する開閉自在の排出体９を設けてある。
【００２０】
更に、前記した微生物ｃは、図３に示すように、坦体（坦体とは、表面等に微生物などの触媒の活性成分を付着させて、該触媒を支持するための物質。）１０を用いて培養してもよく、この坦体１０は、木質系のチップやおが屑，炭化物，トルマリン粉粒体あるいはセラミック粉粒体などの多孔質や微生物ｃの付着しやすい形態を有するものを用いることができ、このセラミック製の場合には、その焼結製造にあって、図３において○印部を拡大して示すように、トルマリンｔの粉体を５％〜５０％程度混入させて焼成することもある。
また、セラミック製の坦体１０は、後記する移送手段２と槽本体１内の槽壁とによって、固形状の有機性廃棄物ｂの粉砕や磨り潰しあるいは引き千切りを行う際に、所定の硬度が破砕促進剤となって、前記効果を助長させることができるもので、その大きさは、例えば、０．５ｍｍ〜１５．０ｍｍ程度に成形される。
【００２１】
前記した移送手段２は、槽本体１内の底部槽壁１ａ付近に設けて有機性廃棄物ｂを移送するもので、槽本体１内の一側の槽壁１ｂから他側の槽壁１ｃに渡って略水平に横架させた回転軸１１へ所定ピッチの螺旋状の送り羽根１２を周設したスクリューコンベアである。
この送り羽根１２は、その外周縁は、図１に示すように、側面形状が円形に形成されているもので、槽本体１内の一側の槽壁１ｂ近傍から他側の槽壁１ｃ近傍にわたって連続した螺旋形状に設けられている。
また、この送り羽根１２の外周縁と槽本体１の底部槽壁１ａとの間に、有機性廃棄物ｂが介在する隙間１３を形成させてある。すなわち、この隙間１３は、移送手段２における送り羽根１２の円形外周縁と同心状に形成される底部槽壁１ａによって形成されるもので、０ｍｍ〜１５ｍｍ程度に設けられた、固形状の有機性廃棄物ｂの粉砕や磨り潰しあるいは引き千切り作用が行われる領域で、この有機性廃棄物ｂの粉砕や磨り潰しあるいは引き千切り作用は、有機性廃棄物ｂと送り羽根１２および底部槽壁１ａとの相互摩擦や、有機性廃棄物ｂに対する送り羽根１２と底部槽壁１ａとの圧接により行われる。
【００２２】
この底部槽壁１ａは、前記したように送り羽根１２の円形外周縁と同心状の略半円状に形成され、移送手段２の軸方向を横断した方向（図１に示す状態）にあっては、移送手段２の送り羽根１２の略下半部を取り囲むように底部槽壁１ａが対応し、該底部槽壁１ａの略半円状部において送り羽根１２とに隙間１３が設けられている。
更に、槽本体１にあって、略半円状に形成された底部槽壁１ａの両上端部は、図１に示すように、それぞれ側壁１ｄ，１ｅを立設してあり、この側壁１ｄ，１ｅと一側の槽壁１ｂ，他側の槽壁１ｃとにより箱形の容器を構成している。
また、移送手段２の回転軸１１は、槽本体１の近傍に設けた駆動手段１４により、時計方向あるいは反時計方向へ連続的に、あるいは間欠的に回転されるもので、電動や油圧等のモータ１５の回転を減速機１６により所定の回転速度に調整する。
【００２３】
前記した取り入れ手段３は、槽本体１の適所に、例えば、槽本体１の上部に設けて該槽本体１内へ外気を供給するもので、槽本体１に設けた通孔３ａを常時開放状態にした自然送気か、あるいは、開閉弁（図示せず）の操作により適宜間欠的な通気操作を行う。この外気は、常温の大気や温度調整された冷風や温風であって、送風機等の強制的な圧送手段１７により行うこともある。
【００２４】
前記した排気手段４は、槽本体１の適所に設けて該槽本体１内の排気を行うもので、槽本体１に設けた通孔４ａを常時開放状態にした自然排気か、あるいは、排風機等の強制的な排風手段１８により排気する。
この排気は、有機性廃棄物ｂから立ちのぼる臭気や、微生物ｃによって有機性廃棄物ｂを醗酵分解する工程の際に発生する水蒸気や炭酸ガスなどの気体を槽本体１外へ排出させる。この排気中の臭気除去の必要がある場合には、通孔４ａの排気ライン途中に、コイルヒータや水などの触媒干渉等による脱臭手段１９を設けることもできる。
【００２５】
なお、図１において２０は、槽本体１に設けて該槽本体１を加温する加温手段で、パネルヒーターや温水による熱源が用いられるもので、槽本体１内の温度が低下したした場合には、この保温手段２０を稼働させて槽本体１内の温度を適温に保つ。
なお、この温度管理は、槽本体１の適所に設けた温度検出手段２１により検出した温度信号を制御手段２２に送って、この制御手段２２により適宜加温手段２０の運転を制御して、槽本体１内の温度管理を行う。この場合、取り入れ手段３に温度調整された温風を送り込むことで槽本体１内の温度管理ができるものであり、また、加温手段とこの温風の吹き込みとを併用した制御操作も行うことができる。更に、加温手段として、温風ヒーター吸気口に取り付けて使用することもできる。
【００２６】
前述のように構成される本発明に係る第一実施例の有機性廃棄物の処理装置Ａは、以下に述べる作用を奏する。
移送手段２を駆動手段１４により駆動させ、槽本体１内へその投入体５から微生物ｃと共に有機性廃棄物ｂを投入して、移送手段２により微生物ｃ入りの有機性廃棄物ｃを槽本体１内の一側の槽壁１ｂ側にあるものは、この一側の槽壁１ｂから他側の槽壁１ｃへ向かって、上下方向や側方向との有機性廃棄物ｂが互いに撹拌され混合されながら移送される。
この移送速度は、処理する有機性廃棄物ｂの種類や槽本体１内の収容量などによって適宜異なるものであるが、例えば、０．１回転／ｓｅｃ〜１５回転／ｍｉｎ程度の速度により行われる。
また、移送手段２の運転状態は、連続的あるいは間欠的に行われるもので、間欠運転の場合は、例えば、３０〜４０分稼働ごと１０〜２０分程度停止させて静置させる等の運転サイクルで行われるもので、この運転サイクルは、適宜変更し得る。
【００２７】
この移送手段２によって有機性廃棄物ｂはその送り羽根１２により移送されるものであるが、該有機性廃棄物ｂは送り羽根１２と回転軸１１と底部槽壁１ａとに圧力的に押し付けられて流動と対流および有機性廃棄物ｂへの空気の供給を繰り返しながら、塊状や固形状となったものは押し潰されたり、送り羽根１２の外周縁と底部槽壁１ａとに形成された隙間１３に押し込まれて介在させられ、粉砕や磨り潰し，引き千切りなどの外力が与えられ、特に、硬質のもの（例えば、貝殻や骨類）は細かくこなれ、次第に、その塊状の大きさを次第に細かく小さくする、あるいは、長尺状のものは、その長さを短くしていく。
【００２８】
そして、この移送手段２の移送に伴って、槽本体１の他側の槽壁１ｃに達した有機性廃棄物ｂは、該移送手段２によって該有機性廃棄物ｂに掛かる移送圧，押送圧によりこの他側の槽壁１ｃの略垂直面に沿ってこの有機性廃棄物ｂは、図２において（１）に示すように、移送手段２上より高く隆起させられる。
【００２９】
この有機性廃棄物ｂの隆起は、移送圧，押送圧によって所定高さまで継続するものであるが、該有機性廃棄物ｂの粘度や結合状態あるいはこの有機性廃棄物ｂ自体の自重によって前記隆起後、再び、移送手段２上へ落下する。
このとき、移送手段２による有機性廃棄物ｂの圧送は、次から次へと行われているもので、その移送によって、図２において矢印ｐに示すように、なだらかな傾斜状となって槽本体内の一側の槽壁１ｂ側へ崩れ落ちるように移動し、このとき有機性廃棄物ｂのほぐしが行われると共に、空気との接触が行われ、同図において（２）に示す斜め状態となった堆積部を形成する。
【００３０】
したがって、移送手段２の連続運転により有機性廃棄物ｂは継続して移送されることで、その変化する先頭部が、できるだけ槽本体内の一側の槽壁１ｂ側に戻され、また、該槽本体１内の底部槽壁１ａに戻される。そして、再び、槽本体１内の一側の槽壁１ｂから他側の槽壁１ｃへ向かって移送する循環流動運動が行われる。
そのため、移送手段２による槽本体１内の一側の槽壁１ｂから他側の槽壁１ｃへ向かって移送の間に、前記同様に、この有機性廃棄物ｂは、送り羽根１２と回転軸１１と底部槽壁１ａとに圧力的に再び押し付けられて流動と対流および有機性廃棄物ｂへの空気の供給を繰り返しながら、まだ塊状や固形状となったているものは再度押し潰されたり、送り羽根１２の外周縁と底部槽壁１ａとに形成された隙間１３に押し込まれて介在させられ、この隙間１３において粉砕や磨り潰し，引き千切りなどの外力が与えられ、更に、その塊状の大きさをもっと細かく小さくする、あるいは、長尺状のものはその長さを短くしていく。
このより多くの微生物ｃが付着して、細分化されることで有機性廃棄物ｂの表面積が可及的拡大され、微生物ｃによる醗酵分解をより一層促進させることができる。
【００３１】
この間に、有機性廃棄物ｂは、この有機性廃棄物ｂ内に混在させた微生物ｃによる醗酵分解（増殖）作用により、その多くは炭酸ガスや水蒸気（水）等に分解され、気体となったものは、槽本体１の上部に設けた排気手段４から自然状態あるいは排気手段１８により排気され、大気に放出される。このとき、この気体に悪臭を有する場合には、脱臭手段１９により、例えば、コイルヒータを用いた場合には、このコイルヒータを通過する間に前記気体に燃焼を与えて脱臭する。
また、槽本体１内に気圧変化を与えないように、槽本体１の上部に設けた取り入れ手段３により外気をこの槽本体１内へ送る。
【００３２】
そして、有機性廃棄物ｂの処理、いわゆる、その全体容積を縮小させた減容化や脱水処理などが終了すれば、槽本体１の底部に設けた排出体９から最終残物を取り除く。なお、この有機性廃棄物の処理装置Ａにあって、一回の処理後と最終残物を取り出す必要はなく、該有機性廃棄物ｂの処理進行状態を観察しながら、槽本体１内において有機性廃棄物ｂが少なくなれば、処理に適した量の範囲内において、新たな有機性廃棄物ｂを追加しながら継続してその処理を行うこともできる。
【００３３】
次に、家庭から排出される生ゴミなどの有機性廃棄物ｂの処理の実施例について説明すると、含水率７５％の有機性廃棄物ｂの５０Ｋｇを槽本体１内に投入して、移送手段２を毎秒１回転で駆動した。この移送手段２の運転を４０分連続して行い、該移送手段２の運転を停止し、１５分間、槽本体１内の有機性廃棄物ｂの移動を止め静置させた。また、同様に、４０分間の移送手段２の運転と１５分間の静置工程を行った。この処理サイクルを１日間行ったところ、槽本体１内の底部槽壁１ａには５Ｋｇとなった、有機性廃棄物ｂの全体容積を縮小させた減容化や脱水処理などがなされた最終残物が残った。
移送手段２の回転方向を逆回転にして該移送手段２を駆動すると、この最終残物は送り羽根１２によって一側の槽壁１ｂに向かって底部槽壁１ａに沿って移動する。この状態で、底部槽壁１ａに設けた排出体９の開放状態において、前記最終残物は槽本体１外に取り出された。
なお、この最終残物の取り出しにあっては、吸引手段による吸い出しであっても構わない。
また、処理前の有機性廃棄物ｂとしてアサリの貝殻と牛の骨など硬質部が混在していたが、この最終残物は、貝殻も骨も粉粒状となって跡形もなく、外観は顆粒状に変化して、その全体の含水率も３５％となった乾燥状態であった。
【００３４】
また、前記した条件下において、０．５ｍｍ粒のセラミック製の多数の坦体１０に微生物ｃを付着させて慣用の培養法により増殖させ、槽本体１内へ有機性廃棄物ｂと共に投入して、前記同様の処理サイクルで処理を行ったところ、開始３０時間後に、槽本体１内の底部槽壁１ａに５Ｋｇとなった、有機性廃棄物ｂの全体容積を縮小させた減容化や脱水処理などがなされた最終残物が残った。これによれば、セラミック製の坦体１０が移送手段２による有機性廃棄物ｂの移送に際して、該有機性廃棄物ｂの粉砕などの細分化に大きな効果を発揮することが確認された。
【００３５】
図４および図５において示す有機性廃棄物の処理装置Ａは、第二の実施例を示すもので、この例は、槽本体１内において、移送手段２の上方に均し手段２４を一基設けてある。なお、有機性廃棄物の処理装置Ａにあって、その他の構成は、前記第一実施例と同様の構成となるため、同一部材には同一符号を付してその詳細な説明は前記例を援用し省略する。
【００３６】
すなわち、前記第一実施例においては、槽本体１の他側の槽壁１ｃに達した有機性廃棄物ｂは、該移送手段２によって該有機性廃棄物ｂに掛かる移送圧，押送圧によりこの他側の槽壁１ｃの略垂直面に沿ってこの有機性廃棄物ｂは、移送手段２上より高く隆起させられて、所定隆起後、有機性廃棄物ｂ自体の自重等によって、移送手段２上へ落下するが、図２に示すように、なだらかな傾斜状となる堆積部（２）を形成する。
そのため、同図に示すように、槽本体１内には、有機性廃棄物ｂが堆積されないデッドスペース（３）ができる場合がある。このデッドスペース（３）を解消するために均し手段２４を設けたものである。
【００３７】
この均し手段２４は、槽本体１内において有機性廃棄物ｂの隆起位置に対応するように、図５に示すように、移送手段２と略平行するように、また、図４に示すように、該移送手段２の軸方向とその上下関係が略同一となるように設けられているもので、回転軸２５へ送り羽根２６を連続的に周設したスクリューコンベア式や、図示してないが、掻き戻し棒を多数設けた回転体あるいはコンベアなどが用いられる。
【００３８】
また、回転軸２５には、移送手段２の駆動手段１４と連動するように、チェーンやベルト等の連係部材２７を接続してあるもので、この駆動手段１４により時計回りあるいは反時計回りに回転されるもので、該回転方向は、隆起した有機性廃棄物ｂの均し状況に応じて、有機性廃棄物ｂの均し効果が良好となる回転方向を任意に設定することができる。
なお、均し手段２４の駆動にあっては、図示しない単独の駆動部材を用いてもよく、また、この均し手段２４の移送速度は、移送手段２の移送速度と同速あるいは移送手段２より早いまたは遅く設定される。
【００３９】
この例によれば、移送手段２によって槽本体１内の有機性廃棄物ｂはその送り羽根１２により移送され、その移送過程において該有機性廃棄物ｂは送り羽根１２と回転軸１１と底部槽壁１ａとに圧力的に押し付けられて流動と対流および有機性廃棄物ｂへの空気の供給を繰り返しながら、塊状や固形状となったものは押し潰されたり、送り羽根１２の外周縁と底部槽壁１ａとに形成された隙間１３に押し込まれて介在させられ、粉砕や磨り潰し，引き千切りなどの外力が与えられ、特に、硬質のもの（例えば、貝殻や骨類）は細かくこなれ、次第に、その塊状の大きさを次第に細かく小さくする、あるいは、長尺状のものは、その長さを短くしていく。
【００４０】
そして、この移送手段２の移送に伴って、槽本体１の他側の槽壁１ｃに達した有機性廃棄物ｂは、該移送手段２によって該有機性廃棄物ｂに掛かる移送圧，押送圧によりこの他側の槽壁１ｃの略垂直面に沿ってこの有機性廃棄物ｂは、槽本体１内において、図５に示すように、移送手段２上より高く隆起させられる。
【００４１】
すると、駆動手段１４によって回転される均し手段２４が、この隆起した有機性廃棄物ｂの堆積部を切り崩しながら、この有機性廃棄物ｂを槽本体１内の他側の槽壁１ｃから一側の槽壁１ｂへ向かって移送する。そのため、次々と隆起して流動する有機性廃棄物ｂはこの均し手段２４によって、一側の槽壁１ｂ側の底部槽壁１ａに向かって落下させるので、図５に示すように、槽本体１内のほぼ全容積を有効に使って有機性廃棄物ｂの撹拌混合と流動や対流を行うことができ、これにより、装置Ａ全体の大きさ（特に高さ方向）をできるだけ小さくして、槽本体１において、図２に示すデッドスペース（３）の発生を解消させ、小型に製作することができる。また、槽本体１内の容積率をできるだけ高めることができることで、有機性廃棄物ｂの処理、すなわち、有機性廃棄物ｂの全体容積を縮小させた減容化や脱水処理などがなされる処理能力が向上する。
【００４２】
次に、図６および図７において示す有機性廃棄物の処理装置Ａは、前記した第一実施例を基本として、その要旨は、槽本体１内の移送手段２を複数列で平行状に並設させた第三の実施例を示すもので、その他の構成は、前記第一，二実施例と同様の構成となるため、同一部材には同一符号を付してその詳細な説明は前記例を援用し省略する。
すなわち、槽本体１における側壁１ｄ，１ｅとの間において、有機性廃棄物ｂの移送方向と直交する方向に、二基の移送手段２，２が並べ設けられている。
この移送手段２，２は、図７に示すように、槽本体１内の一側の槽壁１ｂから他側の槽壁１ｃにわたって、略水平に横架させた回転軸１１ａ，１１ｂへ所定ピッチの螺旋状の送り羽根１２ａ，１２ｂを周設したスクリューコンベア状に形成されている。
また、この送り羽根１２ａ，１２ｂは、それぞれが噛み合うことなく、かつ接触することがないように配設されているもので、図７に示すように、送り羽根１２ａ，１２ｂは、その山部と谷部とがそれぞれ対応するように羽根ピッチを揃えて設けてある。
【００４３】
また、移送手段２，２の回転軸１１ａ，１１ｂは、図７に示すように、歯車等の連動部材３０，３１により接続されていて、駆動手段１４における減速機１６を介したモータ１５の駆動は連動回転されるように設けられる。
【００４４】
この例によれば、図８（ａ）に示すように、二基の移送手段２，２をそれぞれ矢印ｍ，ｍ（内回り）に回転させると、この送り羽根１２ａ，１２ｂによって半円形の底部槽壁１ａ，１ａの内端部側いわゆる移送手段２，２の間において槽本体１内の有機性廃棄物ｂはその引き込み（矢印ｍ２方向）動作が行われる。
それに相応してこの有機性廃棄物ｂは、移送手段２，２と底部槽壁１ａ，１ａとの隙間１３ａ，１３ｂに入り込み、前記第一実施例と同様に、粉砕や磨り潰し，引き千切りなどの外力が与えられ、特に、硬質のもの（例えば、貝殻や骨類）は細かくこなれ、次第に、その塊状の大きさを次第に細かく小さくする、あるいは、長尺状のものは、その長さを短くされて、側壁１ｄ，１ｅ側へ向かって押し出される。
【００４５】
また、図８（ｂ）に示すように、二基の移送手段２，２をそれぞれ矢印ｎ，ｎ（外回り）に回転させたときは、この送り羽根１２ａ，１２ｂによって、側壁１ｄ，１ｅ側から槽本体１内の有機性廃棄物ｂはその引き込み（矢印ｎ２方向）動作が行われ、それに相応してこの有機性廃棄物ｂは、移送手段２，２と底部槽壁１ａ，１ａとの隙間１３ａ，１３ｂに入り込み、前記第一実施例と同様に、粉砕や磨り潰し，引き千切りなどの外力が与えられ、特に、硬質のもの（例えば、貝殻や骨類）は細かくこなれ、次第に、その塊状の大きさを次第に細かく小さくする、あるいは、長尺状のものは、その長さを短くされて、半円形の底部槽壁１ａ，１ａの内端部側いわゆる移送手段２，２の間において底部槽壁１ａ，１ａから槽本体１内の上方（矢印２方向）へ向かって押し出される。
更に、図８（ａ），（ｂ）に示すように、二基の移送手段２で、図６，図７，図１０のように基本形の図２，図５，図１１，図１２，図１３，図１４を使うことができる。そこで、図９の上部図では、三基基本形があるが、左二基と右一基の間と、図９の下部図で、左二基と右二基の間に仕切（図示していない）を介在させて、または独立に設置して左右の移送手段２の相互干渉をなくすような構造にしてもよい。
ここで、左右の移送手段２に接触しないようにぎりぎりまで近接して、仕切りを設置すればよい。一方、仕切の代わりに、左右を全くの独立構成（図示していない）にしてもよい。このような仕切りまたは独立構成は車両搭載機にも適用できる。
【００４６】
これにより、槽本体１内における有機性廃棄物ｂの処理、すなわち、有機性廃棄物ｂの全体容積を縮小させた減容化や脱水処理などがなされる処理が、前記第一および第二実施例に示す装置Ａの処理状況と比べて大幅に向上する。
【００４７】
なお、この例にあって、槽本体１内に並設させる移送手段２は、他の複数列に設けることができるもので、図９（ａ）に示すように、移送手段２が側壁１ｄと側壁１ｅとの間に平行状態で三連に、あるいは、図９（ｂ）に示すように、移送手段２が側壁１ｄと側壁１ｅとの間に平行状態で四連に、とのように槽本体１内に設置可能であれば任意の複数列に設けることができる。
また、これら移送手段２の回転方向は、図９においてそれぞれ矢印で示す統一方向か、あるいは、同図におけるそれぞれ反矢印に示す統一方向に設定される。
【００４８】
更に、第三実施例に示す有機性廃棄物の処理装置Ａにあっても、槽本体１内において、移送手段２の上方に均し手段２４を複数基設けることができるもので、均し手段２４自体の構成は、前記第二実施例に示されるものと同様に構成されるものであり、例えば、図１０に示すように、二連状に設けた場合には、それぞれの移送手段２，２の軸方向と略平行するように、また、該それぞれの移送手段２，２の軸方向とその上下関係が略同一となるように設けられているもので、回転軸２５ａ，２５ｂへ送り羽根２６ａ，２６ｂを連続的に周設したスクリューコンベア式や、図示してないが、掻き戻し棒を多数設けた回転体あるいはコンベアなどが用いられる。
【００４９】
また、回転軸２５ａ，２５ｂには、移送手段２，２の駆動手段１４と連動するように、チェーンやベルト等の連係部材２７ａ，２７ｂを接続してあるもので、この駆動手段１４により時計回りあるいは反時計回りに回転される。
【００５０】
この例にあって、駆動手段１４によって回転される均し手段２４，２４が、槽本体１内において隆起した有機性廃棄物ｂの堆積部を切り崩しながら、この有機性廃棄物ｂを槽本体１内の他側の槽壁１ｃから一側の槽壁１ｂへ向かって移送する。そのため、次々と隆起して流動する有機性廃棄物ｂはこの均し手段２４，２４によって、一側の槽壁１ｂ側の底部槽壁１ａに向かって落下させるので、槽本体１内のほぼ全容積を有効に使って有機性廃棄物ｂの撹拌混合と流動や対流を行うことができて、槽本体１内の容積率をできるだけ高めることができて、その結果、有機性廃棄物ｂの処理、いわゆる、有機性廃棄物ｂの全体容積を縮小させた減容化や脱水処理などがなされる処理能力が向上する。
【００５１】
次に、図１１および図１２において示す第四の実施例の有機性廃棄物の処理装置Ａは、前記した第一実施例を基本として、その構成の要旨は、移送手段２における送り羽根１２０ａ，１２０ｂが、回転軸１１に対して有機性廃棄物ｂの送り方向（羽根の向き）を異ならせて設けた例を示すもので、移送手段２における送り羽根１２０ａ，１２０ｂ以外の他の構成は、前記第一，二実施例と同様の構成となるため、同一部材には同一符号を付してその詳細な説明は前記例を援用し省略する。
【００５２】
すなわち、送り羽根は、回転軸１１の軸方向における略中央部において、送り羽根１２０ａと送り羽根１２０ｂとに二分割してあって、このうち、送り羽根１２０ａは、軸方向における略中央部から槽本体１の一側の槽壁１ｂへ向かって有機性廃棄物ｂを移送するように、また、羽根１２０ｂは、前記送り羽根１２０ａの移送作用とは逆に、軸方向における略中央部から槽本体１の他側の槽壁１ｃへ向かって有機性廃棄物ｂを移送するように設定してある。
【００５３】
したがって、この移送手段２の移送に伴って、送り羽根１２０ａと送り羽根１２０ｂとにより、回転軸１１の中央部から振り割りされるように、槽本体１の一側の槽壁１ｂと他側の槽壁１ｃに達したそれぞれの有機性廃棄物ｂは、該移送手段２によって該有機性廃棄物ｂに掛かる移送圧，押送圧により、この一側の槽壁１ｂと他側の槽壁１ｃの略垂直面に沿って該有機性廃棄物ｂは、図１１（ａ）に示すように、移送手段２上より高く隆起させられる。
【００５４】
この有機性廃棄物ｂの隆起は、移送圧，押送圧によって所定高さまで継続するものであるが、該有機性廃棄物ｂの粘度や結合状態あるいはこの有機性廃棄物ｂ自体の自重によって前記隆起後、再び、移送手段２上へ落下する。
このとき、移送手段２による有機性廃棄物ｂの圧送は、次から次へと行われているもので、その移送によって、図１１（ａ）において矢印ｐに示すように、なだらかな傾斜状となって槽本体内における一側の槽壁１ｂと他側の槽壁１ｃとの中間部、すなわち、回転軸１１の中間部へ崩れ落ちるように移動し、このとき有機性廃棄物ｂのほぐしが行われると共に、空気との接触が行われ、更に、斜め状態となった堆積部を形成する。
【００５５】
そのため、移送手段２の連続運転により有機性廃棄物ｂは継続して移送されることで、その変化する先頭部の有機性廃棄物ｂが、できるだけ前記中間部側に戻され、また、該槽本体１内の底部槽壁１ａに戻される。そして、再び、回転軸１１の中央部（前記中間部）から振り割りされるように、槽本体１内の一側の槽壁１ｂと他側の槽壁１ｃとへ向かって移送する循環流動運動が行われる。
【００５６】
この例にあっては、槽本体１内における移送手段２の軸方向の長さが長くなった場合、すなわち、一側から他側へ流動する有機性廃棄物ｂの移送距離が長くなる場合には、その移送距離を分断して一側の槽壁１ｂと他側の槽壁１ｃとに分かれて送ることで、その処理速度が速くなり、処理効率の向上が図れる。
【００５７】
また、有機性廃棄物ｂの撹拌混合を促進させるために、一本の回転軸１１において、この移送方向の異なる送り羽根を該移送方向の異なるごと交互に３組あるいは４組等の多数組に配設することもできる。
【００５８】
更には、この第四実施例にあっても、図１１（ｂ）に示すように、槽本体１内において、移送手段２の上方に均し手段２４を設けることができるもので、この均し手段２４は、槽本体１内において有機性廃棄物ｂの隆起位置に対応するように、移送手段２と略平行するように、また、該移送手段２の軸方向とその上下関係が略同一となるように設けられているもので、回転軸２５へ送り羽根２６ａ，２６ｂを該回転軸２５の中間部において分断するように周設したスクリューコンベア式や、図示してないが、掻き戻し棒を多数設けた回転体あるいはコンベアなどが用いられる。
【００５９】
また、回転軸２５には、移送手段２の駆動手段１４と連動するように、チェーンやベルト等の連係部材２７を接続してあるもので、この駆動手段１４により時計回りあるいは反時計回りに回転される。
【００６０】
したがって、この均し手段２４よって、槽本体１内の一側の槽壁１ｂと他側の槽壁１ｃとに沿って隆起した有機性廃棄物ｂは、図１１（ｂ）において矢印に示すように、回転軸２５の回転により該回転軸２５の中間部へ向かって移送されることで前記隆起部が徐々に平らになり、槽本体１内において有機性廃棄物ｂ層がほぼ平らになり、移送手段２による有機性廃棄物ｂの移送および撹拌・混合更には粉砕や磨り潰し，引き千切りなどの処理効率が一層良好となる。
【００６１】
また、これら移送手段２や均し手段２４は、前記第三実施例に示すように、槽本体１の側壁１ｄと１ｅとの間に、それぞれ複数基設けることができ、その配置形態も同様の形態が採用し得る。
【００６２】
前記した第一実施例から第四実施例における有機性廃棄物の処理装置Ａにあって、移送手段２には掻き上げ部材３５を突設することもある。この掻き上げ部材３５によれば、槽本体１内の有機性廃棄物ｂは、移送手段２によって該有機性廃棄物２に掛かる移送圧により他側の槽壁１ｃ（第四実施例においては一側の槽壁１ｂにも）に沿って隆起されるものであり、この有機性廃棄物ｂの隆起部に対応させて、移送手段２における回転軸１１へこの掻き上げ部材３５を突出するように、かつ、回転によって、底部槽壁１ａに干渉しないように付設させてある。
これにより、有機性廃棄物ｂの隆起を助長させることができて、槽本体１内における有機性廃棄物ｂの流動循環運動が円滑に行われる。
【００６３】
なお、この掻き上げ部材３５の取付形態は、有機性廃棄物ｂが槽本体１内において一側の槽壁１ｂから他側の槽壁１ｃに向かって移送される場合は、図１２（ａ），（ｂ）に示すように、他側の槽壁１ｃの近傍において回転軸１１に設けてある。また、有機性廃棄物ｂが槽本体１内において回転軸の中間部から一側の槽壁１ｂと他側の槽壁１ｃとへ向かって振り分け状態に移送される場合は、図１３（ａ），（ｂ）に示すように、一側の槽壁１ｂと他側の槽壁１ｃとの近傍において回転軸１１に設けてある。
いずれの掻き上げ部材３５の取付形態にあっても、有機性廃棄物ｂの隆起を助長させることができて、槽本体１内における有機性廃棄物ｂの流動循環運動が円滑に行われる。
図１２，図１３に示す掻き上げ部材３５の取付形態は、掻き上げ部材３５の技術思想を記載するもので、掻き上げ部材３５と槽壁１ｃの間は開いて図示してあるが、掻き上げ部材３５と槽壁（１ｃ，１ｂ）の間隔は狭いほどよく、掻き上げ部材３５と槽壁（１ｂ，１ｃ）の隙間に有機性廃棄物ｂの侵入が抑えられ、隙間に有機性廃棄物ｂが侵入しても槽壁（１ｂ，１ｃ）に有機性廃棄物ｂの付着残存を防ぎ、掻き上げ部材３５の作動をよくすることができる。
そして、掻き上げ能力を上げるには掻き上げ部材３５の表面積を大きくすればよい。送り羽根１２による有機性廃棄物ｂの移送量より掻き上げ部材３５による有機性廃棄物ｂの移送量を多くして駆動手段１４の負荷を軽減することができる。なお、掻き上げ部材３５と槽壁１ｃの隙間はある程度開いても、掻き上げ部材３５の効果はあるが隙間は狭い方がよい。
【００６４】
また、前記した第一実施例から第四実施例における有機性廃棄物の処理装置Ａにあって、図１４に示すように、移送手段２における送り羽根１２（送り羽根１２のみ図示して、送り羽根１２ａ，１２ｂ，１２０ａ，１２０ｂには図示されない）には、貫通した孔３７を設けてあるもので、羽根の表面積を可及的減少させて、有機性廃棄物ｂの送り羽根１２，１２ａ，１２ｂ，１２０ａ，１２０ｂへの付着を防止する。
更に、送り羽根１２の孔３７により移送する有機性廃棄物ｂと回転する送り羽根１２との接触面積が可及的減少するので、移送する有機性廃棄物ｂと送り羽根１２との動的な摩擦が減少し、モータ１５への負荷も軽減されてモータ１５の回転が円滑に行われる。
更には、図１９に示す有機性廃棄物の処理装置Ａは、図１４に示す有機性廃棄物の処理装置Ａの発展的な実施例である。
この図１９に示す有機性廃棄物の処理装置Ａにあって、掻き上げ部材３５と槽壁（１ｃ，１ｂ）の間隔は狭いほどよく、掻き上げ部材３５と槽壁（１ｂ，１ｃ）の隙間に有機性廃棄物ｂの侵入が抑えられ、隙間に有機性廃棄物ｂが侵入しても槽壁（１ｂ，１ｃ）に有機性廃棄物ｂの付着残存を防ぎ、掻き上げ部材３５の作動をよくすることができる。そして、掻き上げ能力を上げるには掻き上げ部材３５の表面積を大きくすればよい。
送り羽根１２の取付部材４０は、１２０度の間隔で回転軸１１に設置されている。送り羽根１２による有機性廃棄物ｂの移送量より掻き上げ部材３５による有機性廃棄物ｂの移送量を多くして駆動手段１４の負荷を軽減することができる。
補助羽根は送り羽根１２がない所に有機性廃棄物ｂを滞留させないで、掻き上げ効果も果たしながら円滑に有機性廃棄物ｂを円滑に攪拌混合させ移送するためでのものである。
送り羽根１２の孔３７は、有機性廃棄物ｂとの接触面積を少なくして駆動手段１４の負荷を軽減するためのものである。
なお、送り羽根１２のピッチＬ１と送り羽根１２の直径Ｈ１を等しく、または略等しくすることによって、有機性廃棄物ｂの攪拌移送をより効率的にすることができる。
図２０は、図１９において示される移送手段２をＸ−Ｘ線において断面した図である。送り羽根１２を支持する取付部材４０は、回転軸１１へ１２０度おきに突出させた状態で取り付けられている。送り羽根１２の幅は不均等でもよく、図２０に示すように、送り羽根１２の幅は、２４０度ではｙ２とすると、１２０度ではｙ１＝ｙ２×２／３に設置するとよい。
例えば、１２０度内では幅ｙ１が２０ｍｍで、残りはの２４０度では幅ｙ２が３０ｍｍのようにすると、有機性廃棄物ｂの撹拌移送による負荷が少なくてすむことが実施例で確認されている。
【００６５】
なお、前記した本発明実施例における各例の有機性廃棄物の処理装置Ａは、図示してないが、貨物車輌の荷台にその全体を設置することで、有機性廃棄物ｂの発生現場へこの貨物車輌によって移動し、有機性廃棄物ｂの発生現場において該有機性廃棄物ｂを処理、いわゆる、有機性廃棄物ｂの全体容積を縮小させた減容化や脱水処理などがなされる処理を行うことができる。
【００６６】
次に、本発明に関する有機性廃棄物の処理装置の第五の実施例を図面に基づいて説明する。
図１５〜図１８においてＡは、第五実施例における有機性廃棄物の処理装置であって、もっぱら、家庭や小規模飲食店等において排出される生ゴミなどの有機性廃棄物ｂを減容化する処理を行うものであり、槽本体１と、移送手段２と、取り入れ手段３と、排気手段４とにより基本的に構成される。
なお、生ゴミや有機性汚泥などの有機性廃棄物ｂは、例えば、廃棄される穀類や野菜，果物，種子類，海藻類などの一般的な有機物で、微生物ｃによる醗酵分解が可能な物質である。場合によっては、廃棄される魚や鳥，豚，牛などの肉類や骨類更には卵殻や貝殻類等も処理することができるが、これら貝殻や骨などは機構上、投入前に細かく砕いて投入する必要がある。
【００６７】
前記した槽本体１は、内部を空洞状に形成してその上部に開口状態となった有機性廃棄物ｂの投入体５を設けてあって、この投入体５から有機性廃棄物ｂおよび前記した微生物ｃを収容する。
また、投入体５は、その開口状態を閉塞および開放を行う蓋体７がヒンジや蝶番などの接続部材により開閉自在に取り付けられている。
更に、この槽本体１の底部槽壁１ａは、後記する移送手段２の回転軸１１を中心とした回転運動に相応するように、図１７に示すように、該回転軸１１と同心円となる半円形状に形成されている。
【００６８】
前記した移送手段２は、槽本体１内の底部１ａ付近に設けて有機性廃棄物ｂおよび微生物ｃを移送しつつ、その撹拌と混合運動を行う。
更に、この移送手段２は、槽本体１へ略水平に取り付けた回転軸１１と、この回転軸１１へ取り付けた送り羽根１２と、回転軸１１の一端部に取り付けた駆動手段１４とを有する。
【００６９】
前記した送り羽根１２は、駆動手段１４により回転軸１１が回転したとき、図１５に示すように、槽本体１の一側部▲１▼からこの槽本体１の他側部▲２▼へ向かって該槽本体１に収容された有機性廃棄物ｂおよび微生物ｃを移送（撹拌と混合運動を含む）する第一送り羽根１２ｃと、槽本体１の他側部▲２▼からこの槽本体１の一側部▲１▼へ向かって該槽本体１に収容された有機性廃棄物ｂおよび微生物ｃを移送（撹拌と混合運動を含む）する第二送り羽根１２ｄとからなる。いわゆる、これら第一送り羽根１２ｃと第二送り羽根１２ｄとが、槽本体１の水平方向における外側から内側へ向かって有機性廃棄物ｂおよび微生物ｃを移送（撹拌と混合運動を含む）する作用を行うものである。
また、これら第一送り羽根１２ｃと第二送り羽根１２ｄとは、槽本体１の水平方向（回転軸１１の軸方向）に対して、第一送り羽根１２ｃが槽本体１の一側部▲１▼の領域の有機性廃棄物ｂおよび微生物ｃに対応し、第二送り羽根１２ｄが槽本体１の他側部▲２▼の領域の有機性廃棄物ｂおよび微生物ｃに対応するように、略二分割された形態を有する。
【００７０】
更に、図１７に示すように、このうち、第一送り羽根１２ｃは、回転軸１１の軸方向に対して、該回転軸１１の始端側（一側壁である槽壁１ｂ側からみて）から終端側へ向かうにしたがって、回転軸１１を中心として３０゜〜１２０゜の範囲に、好ましくは９０゜の範囲において、槽本体１内の底部槽壁１ａとの当接位置が変化する位相を形成させたスパイラル状に設けられている。
また、第二送り羽根１２ｄは、回転軸１１の軸方向に対して、該回転軸１１の始端側（一側壁である槽壁１ｂ側からみて）から終端側へ向かうにしたがって、回転軸１１を中心として３０゜〜１２０゜の範囲に、好ましくは９０゜の範囲において、槽本体１内の底部槽壁１ａとの当接位置が変化する位相を形成させたスパイラル状に設けられている。
更には、回転軸１１の軸方向において、第一送り羽根１２ｃの後側縁部と第二送り羽根１２ｄの前側縁部とは、図１７に示すように、回転軸１１を中心として略１８０゜の位相差を有するように取り付けられている。
また、これら送り羽根１２における第一送り羽根１２ｃと第二送り羽根１２ｄは、回転軸１１へ所定の隙間（図１４における孔３７に相応する）を設けて、取付部材４０により取り付けることで、第一送り羽根１２ｃと第二送り羽根１２ｄの表面積を可及的減少させて、有機性廃棄物ｂの送り羽根１２ｃ，１２ｄへの付着を防止と駆動手段１４への負荷を軽減することができる。
【００７１】
この送り羽根１２における第一送り羽根１２ｃと第二送り羽根１２ｄとにあって、これら第一送り羽根１２ｃと第二送り羽根１２ｄとの回転外周縁部が槽本体１の底部１ａに当接するもので、この送り羽根１２における第一送り羽根１２ｃと第二送り羽根１２ｄとの回転外周縁部に、図１８に示すように、ラバー材などの弾性作用と底部（底部槽壁）１ａとの密着性，スクレーパー性とを有する摺擦部材４１を交換自在に設けてある。この摺擦部材４１の取り付けにあっては、例えば、同図に示すように、取付部材４０へ溶着等した第一送り羽根１２ｃと第二送り羽根１２ｄへ押さえ部材４１ａを介してビス等の止着部材４１ｂにより設けられる。
これにより、槽本体１の底部１ａに付着残存しようとする有機性廃棄物ｂおよび微生物ｃをもれなく掻き取ることができると共に、底部槽壁１ａに有機性廃棄物ｂ等の処理物が付着しにくくなることで、腐敗臭等の発生を防ぐ効果を兼ね備えることができる。
【００７２】
前記した取り入れ手段３は、槽本体１の適所に設けて、該槽本体１内へ外気を供給する。
また、前記した排気手段４は、槽本体１の適所に設けて、該槽本体１内の排気を行うものである。
これら取り入れ手段３および排気手段４は、通常は、槽本体１の開口部に設けた蓋体７に開口させた通孔４２を常時開放状態にした自然送気および自然排気によるものである。なお、図示してないが、送排風機等の強制的な手段により送排気を行ってもよい。
更に、この通孔４２には、異物等の侵入を防止するために網等の遮蔽部材４３を張設してある。
【００７３】
なお、前記回転軸１１を回転させる駆動手段１４は、槽本体１の槽壁１ｃより突出した該回転軸１１の外端部へ固着した手動式の手回しハンドル４４が用いられる。また、図示してないが、電動や油圧等のモータも用いることができるもので、この場合、連続や間欠に運転されるもので、間欠回転させるときは、タイマーにより制御することもできる。
【００７４】
前記回転軸１１において、槽本体１内における槽壁１ｂ，１ｃの近傍部には、図１５，図１６に示すように、該回転軸１１より放射状に突出する掻き上げ部材３５を取り付けてあるもので、該掻き上げ部材３５にあって、この回転軸１１の円周方向における最も遠い部位は、槽本体１の底部１ａに当接あるいは近接し、槽壁１ｂ，１ｃ面の対応部は、この槽壁１ｂ，１ｃ面に当接あるいは近接している。
これにより、この槽壁１ｂ，１ｃ部に停滞しやすい、あるいは該槽壁１ｂ，１ｃに張り付いた有機性廃棄物ｂおよび微生物ｃを該掻き上げ部材３５によって剥がし取って、槽本体１の内部方向へ移動できるようにする。
なお、槽本体１の適所には、該槽本体１内を所定温度に加温する加温手段（図示せず）を設けることもあって、これにより、有機性廃棄物ｂに対する微生物ｃの活動を良好にさせ、分解処理効率を向上させる。
【００７５】
前述のように構成される本発明に係る第五実施例の有機性廃棄物の処理装置Ａは、以下に述べる作用を奏する。
槽本体１内へその投入体５から微生物ｃと共に生ゴミなどの有機性廃棄物ｂを投入する。
そして、この槽本体１内に設けられた移送手段２を駆動手段１４により駆動させて、移送手段２における送り羽根１２を数回回転させると、槽本体１内の有機性廃棄物ｂと微生物ｃとは撹拌混合される。なお、駆動手段１４は所定回数の回転の後はその作動を停止させる。
このとき、この微生物ｃ入りの有機性廃棄物ｃは、移送手段２における送り羽根１２の第一送り羽根１２ｃが、図１６における矢印ｍに示すように、槽本体１の一側部▲１▼からこの槽本体の他側部▲２▼へ向かって、かつ、図１５における矢印ｍに示すように、槽本体１の底部１ａから該槽本体１の上部開口部へ向かって移送されつつ、撹拌と混合運動が行われる。
同様に、第二送り羽根１２ｄが、前記第一送り羽根１２ｃの作用とは反対に、図１６における矢印ｎに示すように、槽本体１の他側部▲２▼からこの槽本体１の一側部▲１▼へ向かって、かつ、図１５における矢印ｍに示すように、槽本体１の底部１ａからこの槽本体１の上部開口部へ向かって微生物ｃ入りの有機性廃棄物ｃを移送させつつ、その撹拌と混合運動が行われることで、槽本体１の水平方向における外側から内側へ向かって、かつ、槽本体１の底部から該槽本体１の中間部あるいは上方部（同様にこの作用と逆の作動も同時進行で行われる）への有機性廃棄物ｂおよび微生物ｃが移送による撹拌と混合が行われる。
【００７６】
この移送による撹拌と混合運動の間に、有機性廃棄物ｂは、この有機性廃棄物ｂ内に混在させた微生物ｃによる醗酵分解（増殖）作用により、その多くは炭酸ガスや水蒸気（水）等に分解され、気体となったものは、槽本体１の上部に設けた排気手段４から自然状態により排気され、大気に放出される。また、有機性廃棄物ｂから生じた水分あるいは分解された水分は、微生物ｃにより分解されるときにより生ずる発熱によってその多くは水蒸気となって排気手段４を経て外部へ排出される。このとき、微生物ｃによる分解処理によって生ずる発熱により、水分は蒸発化されることもある。
これに相応して、自然状態による吸気により、槽本体１の上部に設けた取り入れ手段３により外気がこの槽本体１内へ送られる。
【００７７】
そして、有機性廃棄物ｂの処理、いわゆる、その全体容積を縮小させた減容化や脱水処理などが終了すれば、この有機性廃棄物ｂの処理進行状態を観察しながら、槽本体１内において有機性廃棄物ｂが少なくなれば、処理に適した量の範囲内において、新たな有機性廃棄物ｂあるいは微生物ｃを追加しながら継続してその処理を行うこともできる。
【００７８】
この第五実施例による有機性廃棄物の処理装置Ａにあって、その一実施例を示すと、一般家庭から排出される生ゴミ処理に用いたとき、その量に相応して、槽本体１の内容積に占める微生物ｃの割合を６０リットルに形成し、一般家庭において毎日３Ｋｇ排出されるとして、微生物ｃを６０リットル用意した。この微生物ｃを槽本体１に収容し、生ゴミｂを３Ｋｇこの槽本体１内へ投入した。なお、微生物ｃと生ゴミｂとの割合は、概ね５％〜７％であることが好ましい。
そして、駆動手段１４であるハンドル４４を３回回転させて、槽本体１内の生ゴミｂと微生物ｃとを、移送手段２による移送と撹拌と混合運動とを与えて静置させた。
翌日、槽本体１内を観察したところ、生ゴミｂはその９０％が分解処理され、目視により槽本体１内にあって生ゴミｂの姿形がなくなり、いわゆる減容化されたことが確認された。
したがって、また、当日排出された新たな生ゴミｂの３Ｋｇを槽本体１内へ投入して、駆動手段１４を操作して送り羽根１２を３回回転させて静置させた。
【００７９】
こうして、３０日間、生ゴミｂの３Ｋｇの投入と、駆動手段１４による移送手段２の運転とを毎日繰り返して行ったところ、３Ｋｇ×３０日＝９０Ｋｇがことごとく分解処理され、そのときの槽本体１内は、該槽本体１内に残存した物質の全体容量は６５リットルとなっていて、処理開始前の６３リットルと比較して若干の増量はみられたものの、そのほとんどは、粉粒体状の細かな物質に変化しており、これらから発する臭いは、若干の異臭は観測できたが、日常の生活に影響を与える程の臭いは発していなかった。
なお、この３０日間において、魚や鳥、豚などの骨や貝殻も、投入前にできるだけ細かく砕いた後に生ゴミｃと一緒に投入したところ、最終的に、この期間においては、少し塊状に残存したが、もう少し処理期間を延長させることで、全て分解処理できるものであった。
【００８０】
また、３１日目の生ゴミ処理として、槽本体１内の内容物を全て取り出して、新たな微生物ｃを収容させた新規な処理を行うことも考えられるが、槽本体１内の微生物ｃにはまだ十分な分解処理能力が存在しており、槽本体１内の残存物質の一部（例えば、半分）を取り出し、また、当初の６０リットルとなるように微生物ｃを補給することが最善手と思われる。槽本体１から取り出された残存物質の半分は、そのままの状態で肥料に使用でき、例えば、家庭菜園や庭木，花などへの施肥として使用できた。

[0026]
The organic waste treatment apparatus A of the first embodiment according to the present invention configured as described above has the following effects.
The transporting means 2 is driven by the driving means 14, and the organic waste b together with the microorganisms c is charged into the tank main body 1 from the input body 5. The organic wastes b on the one side of the tank wall 1b in the vertical direction and the side direction are mixed with each other from the one side of the tank wall 1b toward the other side of the tank wall 1c. It is transported while being performed.
The transfer speed varies depending on the type of the organic waste b to be treated, the capacity of the tank body 1, and the like, but is, for example, set at a speed of about 0.1 rotation / sec to 15 rotation / min. .
The operation state of the transfer means 2 is continuously or intermittently performed. In the case of intermittent operation, for example, an operation cycle of stopping for about 10 to 20 minutes every 30 to 40 minutes of operation and allowing the apparatus to stand still is performed. This operation cycle can be changed as appropriate.
[0027]
The organic waste b is transferred by the feed blades 12 by the transfer means 2, and the organic waste b is pressed against the feed blades 12, the rotating shaft 11, and the bottom tank wall 1a. While repeating the flow and convection and the supply of air to the organic waste b, the lump or solid matter is crushed or the gap formed between the outer peripheral edge of the feed blade 12 and the bottom tank wall 1a. 13 to be interposed and applied with an external force such as crushing, crushing, and shredding. To make it smaller or long, shorten its length.
[0028]
The organic waste b that has reached the tank wall 1c on the other side of the tank body 1 with the transfer of the transfer means 2 is transferred and pushed by the transfer means 2 on the organic waste b. Thus, the organic waste b is raised higher than the transfer means 2 along the substantially vertical surface of the other side of the tank wall 1c as shown in FIG.
[0029]
The uplift of the organic waste b continues to a predetermined height due to the transfer pressure and the pushing pressure. However, the uplift occurs due to the viscosity and the bonding state of the organic waste b or the weight of the organic waste b itself. Thereafter, it falls again onto the transfer means 2.
At this time, the pumping of the organic waste b by the transfer means 2 is performed from one to the next, and by the transfer, the tank becomes a gentle slope as shown by an arrow p in FIG. It moves so as to fall down to the tank wall 1b side on one side of the main body, and at this time, the organic waste b is loosened, and at the same time, is brought into contact with air. A deposited portion is formed.
[0030]
Therefore, the organic waste b is continuously transferred by the continuous operation of the transfer means 2 so that the changing head is returned to the tank wall 1b on one side in the tank body as much as possible. It is returned to the bottom tank wall 1a in the tank body 1. Then, a circulating flow movement is again performed in which the tank wall 1b on one side in the tank body 1 is transferred to the tank wall 1c on the other side.
Therefore, during the transfer by the transfer means 2 from the tank wall 1b on one side in the tank body 1 to the tank wall 1c on the other side, similarly, as described above, the organic waste b is transferred to the feed blade 12 and the rotating shaft. 11 and the bottom tank wall 1a are pressurized again to repeat flow and convection and supply of air to the organic waste b. Is pushed into a gap 13 formed between the outer peripheral edge of the feed blade 12 and the bottom tank wall 1a and is interposed. In this gap 13, an external force such as crushing, grinding, and shredding is applied. Reduce the size more finely, or reduce the length of long ones.
The surface area of the organic waste b is expanded as much as possible by adhering and subdividing the more microorganisms c, and the fermentation decomposition by the microorganisms c can be further promoted.
[0031]
During this time, most of the organic waste b is decomposed into carbon dioxide gas, water vapor (water), etc. by the fermentation decomposition (proliferation) action of the microorganism c mixed in the organic waste b, and becomes a gas. The waste gas is exhausted from the exhaust means 4 provided at the upper part of the tank body 1 in a natural state or by the exhaust means 18 and released to the atmosphere. At this time, if the gas has a bad odor, the gas is deodorized by the deodorizing means 19 by burning the gas while passing through the coil heater, for example, when a coil heater is used.
In addition, outside air is sent into the tank body 1 by the intake means 3 provided on the upper part of the tank body 1 so as not to change the atmospheric pressure in the tank body 1.
[0032]
Then, when the processing of the organic waste b, that is, the volume reduction or dehydration processing in which the entire volume is reduced is completed, the final residue is removed from the discharge body 9 provided at the bottom of the tank body 1. In the organic waste treatment apparatus A, it is not necessary to take out the final residue after one treatment and to observe the progress of the treatment of the organic waste b in the tank main body 1. When the amount of the organic waste b decreases, the treatment can be continuously performed while adding new organic waste b within a range suitable for the treatment.
[0033]
Next, an embodiment of treatment of organic waste b such as garbage discharged from home will be described. 50 kg of organic waste b having a water content of 75% is charged into the tank body 1 and transferred. 2 was driven at one revolution per second. The operation of the transfer means 2 was continuously performed for 40 minutes, the operation of the transfer means 2 was stopped, and the movement of the organic waste b in the tank body 1 was stopped and allowed to stand for 15 minutes. Similarly, the operation of the transfer means 2 for 40 minutes and the stationary step for 15 minutes were performed. When this treatment cycle was carried out for one day, the bottom tank wall 1a in the tank body 1 became 5 kg, and the final residue obtained by reducing the volume of the organic waste b by reducing the total volume and performing dehydration treatment was performed. Things remained.
When the transfer means 2 is driven with the rotation direction of the transfer means 2 reversed, the final residue is moved along the bottom tank wall 1a toward the tank wall 1b on one side by the feed blade 12. In this state, with the discharge body 9 provided on the bottom tank wall 1a opened, the final residue was taken out of the tank body 1.
It should be noted that the removal of the final residue may be suctioned by suction means.
In addition, hard parts such as clam shells and cow bones were mixed as the organic waste b before the treatment, but the final residue was shell and bone in powder and granular form without any traces and granular appearance. It was in a dry state where the water content of the whole became 35%.
[0034]
Further, under the above-described conditions, the microorganisms c are adhered to a large number of ceramic carriers 10 having a particle size of 0.5 mm, multiplied by a conventional culture method, and charged together with the organic waste b into the tank body 1. When the treatment was performed in the same treatment cycle as described above, 30 kg after the start, the weight of the organic waste b was reduced to 5 kg on the bottom tank wall 1a in the tank body 1, and the volume reduction and dehydration of the organic waste b were reduced. The final residue that has been processed remains. According to this, it was confirmed that when the carrier 10 made of ceramic was transferred by the transfer means 2, the ceramic carrier 10 exerted a great effect on pulverization and the like of the organic waste b.
[0035]
An organic waste treatment apparatus A shown in FIGS. 4 and 5 shows a second embodiment. In this example, a leveling means 24 is provided above the transfer means 2 in the tank body 1. It is provided. In the organic waste treatment apparatus A, since the other configuration is the same as that of the first embodiment, the same members are denoted by the same reference numerals, and the detailed description thereof is the same as that of the first embodiment. Incorporated and omitted.
[0036]
That is, in the first embodiment, the organic waste b that has reached the tank wall 1c on the other side of the tank body 1 is transferred by the transfer means 2 by the transfer pressure and the pushing pressure applied to the organic waste b. The organic waste b is raised higher than the transfer means 2 along the substantially vertical plane of the tank wall 1c on the other side. Although falling upward, as shown in FIG. 2, a deposition portion (2) having a gentle slope is formed.
Therefore, as shown in the figure, a dead space (3) where the organic waste b is not deposited may be formed in the tank body 1. In order to eliminate the dead space (3), leveling means 24 is provided.
[0037]
The leveling means 24 is arranged substantially parallel to the transfer means 2 as shown in FIG. 5 so as to correspond to the raised position of the organic waste b in the tank body 1 and as shown in FIG. The transfer means 2 is provided so that the axial direction of the transfer means 2 and its vertical relationship are substantially the same, such as a screw conveyor type in which feed blades 26 are continuously provided around a rotating shaft 25 or not shown. However, a rotating body or a conveyor provided with a large number of scraping bars is used.
[0038]
A linking member 27 such as a chain or a belt is connected to the rotating shaft 25 so as to interlock with the driving means 14 of the transfer means 2, and is rotated clockwise or counterclockwise by the driving means 14. The rotation direction can be arbitrarily set in accordance with the leveling condition of the raised organic waste b so that the leveling effect of the organic waste b is good.
In driving the leveling means 24, a single drive member (not shown) may be used, and the transfer speed of the leveling means 24 may be the same as the transfer speed of the transfer means 2 or may be the same as that of the transfer means 2. Set earlier or later.
[0039]
According to this example, the organic waste b in the tank body 1 is transferred by the feed blade 12 by the transfer means 2, and in the transfer process, the organic waste b is transferred to the feed blade 12, the rotary shaft 11, and the bottom tank. While repeating the flow and convection and the supply of air to the organic waste b by being pressed against the wall 1a under pressure, the lumps or solids are crushed or the outer peripheral edge and the bottom of the feed blade 12 are crushed. An external force such as crushing, crushing, and shredding is applied to the space 13 formed by being pushed into the gap 13 formed with the tank wall 1a. Particularly, hard materials (for example, shells and bones) are finely broken, and gradually The size of the block is gradually reduced to a small size, or the length of the long one is reduced.
[0040]
The organic waste b that has reached the tank wall 1c on the other side of the tank body 1 with the transfer of the transfer means 2 is transferred and pushed by the transfer means 2 on the organic waste b. Accordingly, the organic waste b is raised higher than the transfer means 2 in the tank body 1 along the substantially vertical plane of the other side of the tank wall 1c as shown in FIG.
[0041]
Then, the leveling means 24 rotated by the driving means 14 cuts off the piled-up portion of the raised organic waste b and removes the organic waste b from the tank wall 1c on the other side in the tank body 1. To the side tank wall 1b. For this reason, the organic waste b which rises and flows one after another is dropped by the leveling means 24 toward the bottom tank wall 1a on the one tank wall 1b side. As shown in FIG. The organic waste b can be stirred and mixed and flow or convection can be performed by effectively using almost the entire volume of the apparatus 1, thereby minimizing the size (especially in the height direction) of the entire apparatus A, In the tank body 1, the generation of the dead space (3) shown in FIG. In addition, since the volume ratio in the tank main body 1 can be increased as much as possible, the processing of the organic waste b, that is, the processing of reducing the volume of the organic waste b by reducing its overall volume, performing dehydration processing, and the like is performed. Ability is improved.
[0042]
Next, an organic waste treatment apparatus A shown in FIGS. 6 and 7 is based on the first embodiment described above, and the gist of the invention is that the transfer means 2 in the tank body 1 are arranged in parallel in a plurality of rows. In the third embodiment, the same components as those of the first and second embodiments are denoted by the same reference numerals, and the detailed description thereof is omitted. Is omitted here.
That is, between the side walls 1d and 1e of the tank main body 1, two transfer means 2 and 2 are provided side by side in a direction orthogonal to the transfer direction of the organic waste b.
As shown in FIG. 7, the transfer means 2 and 2 are arranged at predetermined pitches on the rotating shafts 11a and 11b, which are horizontally extended from the tank wall 1b on one side to the tank wall 1c on the other side in the tank body 1. Is formed in the shape of a screw conveyor around which the spiral feed blades 12a and 12b are provided.
The feed blades 12a and 12b are arranged so that they do not mesh with each other and do not come into contact with each other. As shown in FIG. The blade pitches are arranged so that the valleys correspond to each other.
[0043]
The rotating shafts 11a and 11b of the transfer means 2 and 2 are connected by interlocking members 30 and 31 such as gears as shown in FIG. Are provided so as to be rotated in conjunction with each other.
[0044]
According to this example, as shown in FIG. 8 (a), when the two transfer means 2 and 2 are rotated in the directions of arrows m and m (inward), respectively, the semicircular bottom tank is rotated by the feed blades 12a and 12b. The organic waste b in the tank body 1 is drawn (in the direction of the arrow m2) between the so-called transfer means 2 and 2 at the inner end side of the walls 1a and 1a.
Correspondingly, the organic waste b enters the gaps 13a, 13b between the transfer means 2, 2 and the bottom tank walls 1a, 1a and, like the first embodiment, crushes, grinds, shreds, etc. In particular, hard materials (for example, shells and bones) are finely broken, and the mass is gradually reduced in size, or long is reduced in length. Then, it is extruded toward the side walls 1d and 1e.
[0045]
Further, as shown in FIG. 8 (b), when the two transfer means 2 and 2 are rotated in the directions of arrows n and n (outward rotation), respectively, the feed blades 12a and 12b allow the side walls 1d and 1e to move from the side. The organic waste b in the tank body 1 is drawn (in the direction of arrow n2), and accordingly, the organic waste b is removed from the transfer means 2, 2 and the gap between the bottom tank walls 1a, 1a. 13a and 13b, and an external force such as crushing, crushing, and shredding is applied, as in the first embodiment. Particularly, hard materials (for example, shells and bones) are finely broken down and gradually become lumpy. Is gradually reduced in size, or a long one is shortened in length, so that the bottom portion between the so-called transfer means 2 and 2 at the inner end side of the semicircular bottom tank wall 1a. The upper part of the tank body 1 (arrows) Extruded toward the two directions).
Further, as shown in FIGS. 8 (a) and 8 (b), two transfer means 2 are used to form the basic type shown in FIGS. 6, 5, 11, 12, 12 and 12, as shown in FIGS. 13, FIG. 14 can be used. Therefore, although there are three basic types in the upper view of FIG. 9, there is a partition between the two left and one right and between the two left and right in the lower view of FIG. 9 (not shown). ) May be interposed or independently provided to eliminate the mutual interference between the left and right transfer means 2.
Here, the partition may be installed as close as possible so as not to contact the left and right transfer means 2. On the other hand, instead of the partition, the left and right may be completely independent configurations (not shown). Such a partition or independent configuration can also be applied to a vehicle-mounted machine.
[0046]
Thereby, the processing of the organic waste b in the tank body 1, that is, the processing of reducing the volume of the organic waste b by reducing the total volume thereof and performing the dehydration processing is performed in the first and second embodiments. This is greatly improved as compared with the processing status of the apparatus A shown in the example.
[0047]
Note that, in this example, the transfer means 2 arranged side by side in the tank body 1 can be provided in other plural rows, and as shown in FIG. As shown in FIG. 9 (b), the transfer means 2 is in a parallel state between the side wall 1d and the side wall 1e. Any number of rows can be provided as long as they can be installed in the main body 1.
The rotation directions of the transfer means 2 are set to the unified directions indicated by arrows in FIG. 9 or the unified directions indicated by the opposite arrows in FIG.
[0048]
Further, even in the organic waste treatment apparatus A shown in the third embodiment, a plurality of leveling means 24 can be provided above the transfer means 2 in the tank main body 1. The configuration of 24 itself is the same as that shown in the second embodiment. For example, as shown in FIG. 2 is provided so as to be substantially parallel to the axial direction of the transfer means 2 and so that the vertical direction of the transfer means 2 and the transfer means 2 are substantially the same. A screw conveyor type in which 26a and 26b are continuously provided, a rotating body or a conveyor (not shown) provided with a large number of scraping rods, or the like is used.
[0049]
Further, link members 27a and 27b such as chains and belts are connected to the rotating shafts 25a and 25b so as to interlock with the driving means 14 of the transfer means 2 and 2, and the driving means 14 rotates clockwise. Or rotated counterclockwise.
[0050]
In this example, the leveling means 24, 24 rotated by the driving means 14 cut off the piled-up portion of the organic waste b raised in the tank body 1, and remove the organic waste b from the tank body 1. It is transferred from the other side of the tank wall 1c to the one side of the tank wall 1b. Therefore, the organic waste b that rises and flows one after another is dropped toward the bottom tank wall 1a on the one tank wall 1b side by the leveling means 24, 24. The organic waste b can be stirred and mixed and flow or convection can be performed by effectively using the volume, and the volume ratio in the tank body 1 can be increased as much as possible. As a result, the processing of the organic waste b That is, the processing capacity for reducing the volume of the organic waste b by reducing the total volume thereof and performing dehydration processing is improved.
[0051]
Next, an organic waste treatment apparatus A according to a fourth embodiment shown in FIGS. 11 and 12 is based on the first embodiment described above, and the gist of the configuration is as follows. Reference numeral 120b denotes an example in which the feed direction (the direction of the blades) of the organic waste b is provided differently with respect to the rotating shaft 11, and the other configuration of the transfer means 2 other than the feed blades 120a and 120b is as follows. Since the configuration is the same as that of the first and second embodiments, the same members are denoted by the same reference numerals, and the detailed description thereof will be omitted by using the above examples.
[0052]
That is, the feed blade is divided into a feed blade 120a and a feed blade 120b at a substantially central portion of the rotary shaft 11 in the axial direction, and the feed blade 120a is separated from the tank at a substantially central portion in the axial direction. The blade 120b is moved from a substantially central portion in the axial direction in a direction opposite to the transfer operation of the feed blade 120a so as to transfer the organic waste b toward the tank wall 1b on one side of the main body 1. It is set so as to transfer the organic waste b toward the other side of the tank wall 1c.
[0053]
Therefore, with the transfer of the transfer means 2, the feed blade 120a and the feed blade 120b are separated from the center of the rotating shaft 11 so that the tank wall 1b on one side of the tank body 1 and the feed blade 120b on the other side. Each of the organic wastes b that has reached the tank wall 1c is subjected to a transfer pressure and a pushing pressure applied to the organic waste b by the transfer means 2 so that the one-side tank wall 1b and the other-side tank wall 1c are separated. Along a substantially vertical plane, the organic waste b is raised above the transfer means 2 as shown in FIG.
[0054]
The uplift of the organic waste b continues to a predetermined height due to the transfer pressure and the pushing pressure. However, the uplift occurs due to the viscosity and the bonding state of the organic waste b or the weight of the organic waste b itself. Thereafter, it falls again onto the transfer means 2.
At this time, the pumping of the organic waste b by the transfer means 2 is performed one after another, and by the transfer, as shown by the arrow p in FIG. In the tank body, it moves so as to collapse into an intermediate portion between the tank wall 1b on one side and the tank wall 1c on the other side, that is, an intermediate portion of the rotating shaft 11, and at this time, the organic waste b is loosened. At the same time, contact with the air is made, and further, a slanted deposition portion is formed.
[0055]
Therefore, by continuously transferring the organic waste b by the continuous operation of the transfer means 2, the changing organic waste b at the leading portion is returned to the intermediate portion as much as possible, and It is returned to the bottom tank wall 1a in the main body 1. Then, the circulating fluid motion is transferred to the tank wall 1b on one side and the tank wall 1c on the other side in the tank body 1 so as to be distributed again from the central portion (the intermediate portion) of the rotating shaft 11. Is performed.
[0056]
In this example, when the length of the transfer means 2 in the tank body 1 in the axial direction is long, that is, when the transfer distance of the organic waste b flowing from one side to the other side is long. By dividing the transfer distance and feeding it separately to the tank wall 1b on one side and the tank wall 1c on the other side, the processing speed is increased and the processing efficiency can be improved.
[0057]
Further, in order to promote the stirring and mixing of the organic waste b, the feed blades having different transport directions are alternately formed into a large number of sets such as three sets or four sets for each different rotary direction on one rotating shaft 11. It can also be arranged.
[0058]
Further, even in the fourth embodiment, as shown in FIG. 11 (b), a leveling means 24 can be provided above the transfer means 2 in the tank main body 1. The means 24 is disposed substantially parallel to the transfer means 2 so as to correspond to the raised position of the organic waste b in the tank body 1, and the axial direction of the transfer means 2 and its vertical relationship are substantially the same. A screw conveyor type in which feed blades 26a and 26b are separated from the rotary shaft 25 at an intermediate portion of the rotary shaft 25, or a scraping rod (not shown). A large number of rotating bodies or conveyors are used.
[0059]
A linking member 27 such as a chain or a belt is connected to the rotating shaft 25 so as to interlock with the driving means 14 of the transfer means 2, and is rotated clockwise or counterclockwise by the driving means 14. Is done.
[0060]
Therefore, the organic waste b raised along the tank wall 1b on one side and the tank wall 1c on the other side in the tank main body 1 by the leveling means 24 as shown by an arrow in FIG. In the meantime, the raised portion is gradually flattened by being transferred toward the intermediate portion of the rotating shaft 25 by the rotation of the rotating shaft 25, and the organic waste b layer is substantially flattened in the tank body 1, The transfer efficiency of the organic waste b by the transfer means 2, stirring and mixing, as well as the processing efficiency such as crushing, grinding, shredding, etc., are further improved.
[0061]
Further, as shown in the third embodiment, a plurality of transfer means 2 and leveling means 24 can be provided between the side walls 1d and 1e of the tank body 1, respectively, and the arrangement thereof is also the same. A form may be employed.
[0062]
In the organic waste treatment apparatus A according to the first to fourth embodiments, the transfer means 2 may be provided with a scraping member 35 projecting therefrom. According to the scraping member 35, the organic waste b in the tank body 1 is moved by the transfer pressure applied to the organic waste 2 by the transfer means 2 on the other side of the tank wall 1c. So that the scraping member 35 protrudes to the rotating shaft 11 of the transfer means 2 corresponding to the raised portion of the organic waste b. And, it is provided so as not to interfere with the bottom tank wall 1a by the rotation.
Thereby, the bulging of the organic waste b can be promoted, and the fluid circulation movement of the organic waste b in the tank body 1 is performed smoothly.
[0063]
Note that, when the organic waste b is transferred from the tank wall 1b on one side to the tank wall 1c on the other side in the tank body 1, the attachment form of the scraping member 35 is as shown in FIG. , (B), the rotary shaft 11 is provided near the other side of the tank wall 1c. FIG. 13A shows a case where the organic waste b is transferred from the intermediate portion of the rotating shaft in the tank body 1 to the tank wall 1b on one side and the tank wall 1c on the other side. As shown in (b), the rotary shaft 11 is provided near the tank wall 1b on one side and the tank wall 1c on the other side.
In any of the mounting configurations of the scraping member 35, the bulging of the organic waste b can be promoted, and the flow of the organic waste b in the tank body 1 can be smoothly circulated.
The attachment form of the scraping member 35 shown in FIGS. 12 and 13 describes the technical concept of the scraping member 35, and the space between the scraping member 35 and the tank wall 1c is illustrated as being open. The smaller the distance between the member 35 and the tank wall (1c, 1b) is, the better. The entry of the organic waste b into the gap between the scraping member 35 and the tank wall (1b, 1c) is suppressed, and the organic waste b is placed in the gap. , The organic waste b can be prevented from remaining on the tank walls (1b, 1c) and the operation of the scraping member 35 can be improved.
Then, in order to increase the scraping ability, the surface area of the scraping member 35 may be increased. The transfer amount of the organic waste b by the scraping member 35 is larger than the transfer amount of the organic waste b by the feed blade 12, so that the load on the driving unit 14 can be reduced. In addition, even if the gap between the scraping member 35 and the tank wall 1c is opened to some extent, the scraping member 35 has the effect but the gap is preferably narrow.
[0064]
Further, in the organic waste treatment apparatus A according to the first to fourth embodiments described above, as shown in FIG. 14, the feed blade 12 (only the feed blade 12 is shown in FIG. The blades 12a, 12b, 120a, and 120b (not shown) are provided with through holes 37 so that the surface area of the blades is reduced as much as possible so that the feed blades 12, 12a, It prevents adhesion to 12b, 120a, 120b.
Further, the contact area between the transported organic waste b and the rotating feed blade 12 is reduced as much as possible by the hole 37 of the feed blade 12, so that the dynamic flow between the transferred organic waste b and the feed blade 12 is reduced. The friction is reduced, the load on the motor 15 is reduced, and the rotation of the motor 15 is performed smoothly.
Further, the organic waste treatment apparatus A shown in FIG. 19 is a development example of the organic waste treatment apparatus A shown in FIG.
In the organic waste treatment apparatus A shown in FIG. 19, the smaller the distance between the scraping member 35 and the tank wall (1c, 1b), the better, and the gap between the scraping member 35 and the tank wall (1b, 1c). The organic waste b is prevented from entering the gap, and even if the organic waste b enters the gap, the organic waste b is prevented from remaining on the tank walls (1b, 1c), and the operation of the scraping member 35 is prevented. Can be better. Then, in order to increase the scraping ability, the surface area of the scraping member 35 may be increased.
The attachment members 40 of the feed blade 12 are installed on the rotating shaft 11 at intervals of 120 degrees. The transfer amount of the organic waste b by the scraping member 35 is larger than the transfer amount of the organic waste b by the feed blade 12, so that the load on the driving unit 14 can be reduced.
The auxiliary blades are provided to prevent the organic waste b from staying in a place where the feed blade 12 is not provided, and to smoothly stir and mix the organic waste b while performing a scraping-up effect.
The holes 37 of the feed blade 12 are for reducing the contact area with the organic waste b to reduce the load on the driving means 14.
By making the pitch L1 of the feed blades 12 and the diameter H1 of the feed blades 12 equal or substantially equal, the stirring and transfer of the organic waste b can be made more efficient.
FIG. 20 is a sectional view of the transfer unit 2 shown in FIG. 19 taken along line XX. The attachment member 40 that supports the feed blade 12 is attached to the rotary shaft 11 so as to protrude every 120 degrees. The width of the feed blades 12 may be unequal, and as shown in FIG. 20, if the width of the feed blades 12 is y2 at 240 degrees, it is good to set y1 = y2 × 2/3 at 120 degrees.
For example, when the width y1 is set to 20 mm within 120 degrees and the width y2 is set to 30 mm at the remaining 240 degrees, it is confirmed in the examples that the load due to the stirring and transfer of the organic waste b can be reduced. .
[0065]
Although not shown, the organic waste treatment apparatus A of each example in the above-described embodiment of the present invention is installed on the cargo platform of a freight vehicle so that the organic waste b can be generated at the site where the organic waste b is generated. The organic waste b is moved at the site where the organic waste b is generated by being moved by the cargo vehicle, that is, a process of reducing the total volume of the organic waste b and performing a dehydration process or the like.

Normally, the intake means 3 and the exhaust means 4 are based on natural air supply and natural exhaust in which a through hole 42 opened in the lid 7 provided at the opening of the tank body 1 is always open. Although not shown, air may be sent and exhausted by forced means such as an air blower and exhauster.
Further, a shielding member 43 such as a net is stretched in the through hole 42 in order to prevent intrusion of foreign matters and the like.
[0073]
As the driving means 14 for rotating the rotating shaft 11, a manually operated handle 44 fixed to the outer end of the rotating shaft 11 protruding from the tank wall 1c of the tank body 1 is used. Although not shown, a motor such as an electric motor or a hydraulic motor can be used. In this case, the motor is operated continuously or intermittently. When the motor is rotated intermittently, it can be controlled by a timer.
[0074]
As shown in FIGS. 15 and 16, a scraping member 35 protruding radially from the rotary shaft 11 is attached to the rotary shaft 11 in the vicinity of the tank walls 1b and 1c in the tank main body 1. In the scraping member 35, the farthest part in the circumferential direction of the rotating shaft 11 is in contact with or close to the bottom 1a of the tank body 1, and the corresponding part of the tank walls 1b and 1c is It is in contact with or close to the tank walls 1b, 1c.
As a result, the organic waste b and the microorganism c stuck to the tank walls 1b and 1c or stuck to the tank walls 1b and 1c are peeled off by the scraping member 35 and the inside of the tank body 1 is removed. Be able to move in the direction.
In some cases, a heating means (not shown) for heating the inside of the tank body 1 to a predetermined temperature is provided at an appropriate place of the tank body 1, whereby the activity of the microorganism c on the organic waste b is increased. And the decomposition treatment efficiency is improved.
[0075]
The organic waste treatment apparatus A according to the fifth embodiment of the present invention configured as described above has the following effects.
Organic waste b such as garbage is charged into the tank body 1 together with the microorganism c from the input body 5.
When the transfer means 2 provided in the tank body 1 is driven by the drive means 14 to rotate the feed blades 12 in the transfer means 2 several times, the organic waste b and the microorganism c in the tank body 1 are rotated. Is mixed with stirring. The driving means 14 stops its operation after a predetermined number of rotations.
At this time, the organic waste c containing the microorganism c is transferred to the first sending blade 12c of the sending blade 12 in the transfer means 2 as shown by an arrow m in FIG. From the bottom 1 a of the tank body 1 toward the upper opening of the tank body 1 while stirring from the bottom to the other side (2) of the tank body and as shown by the arrow m in FIG. And a mixed exercise is performed.
Similarly, as shown by an arrow n in FIG. 16, the second feed blade 12d moves from the other side (2) of the tank main body 1 in the opposite direction to the action of the first feed blade 12c. The organic waste c containing microorganisms c is transferred from the bottom 1a of the tank body 1 to the upper opening of the tank body 1 from the bottom 1a toward the side part {circle around (1)} and as indicated by an arrow m in FIG. While the agitating and mixing movements are performed, the tank body 1 is moved from the outside in the horizontal direction to the inside and from the bottom of the tank body 1 to the middle or upper part of the tank body 1 (similarly, The operation opposite to the operation is performed simultaneously.) The organic waste b and the microorganism c are stirred and mixed by transfer.
[0076]
During the agitation and mixing movement by this transfer, the organic waste b is mostly carbon dioxide gas or water vapor (water) due to the fermentation decomposition (proliferation) action of the microorganism c mixed in the organic waste b. The gas that has been decomposed into gas and the like is exhausted in a natural state from exhaust means 4 provided at the upper part of the tank body 1 and released to the atmosphere. Further, most of the water generated from the organic waste b or the decomposed water is converted into water vapor by the heat generated when decomposed by the microorganism c, and is discharged to the outside via the exhaust means 4. At this time, water may be evaporated due to heat generated by the decomposition treatment by the microorganism c.
Correspondingly, the outside air is sent into the tank body 1 by the intake means 3 provided on the upper part of the tank body 1 by the suction in the natural state.
[0077]
Then, when the processing of the organic waste b, that is, the volume reduction or dehydration processing in which the entire volume is reduced is completed, the progress of the processing of the organic waste b is observed while the inside of the tank body 1 is observed. If the amount of the organic waste b decreases, the treatment can be continued while adding a new organic waste b or a new microorganism c within a range suitable for the treatment.
[0078]
In an organic waste treatment apparatus A according to the fifth embodiment, one embodiment thereof is described. When used in the treatment of garbage discharged from ordinary households, the tank main body 1 is used in accordance with the amount thereof. The ratio of the microorganisms c in the internal volume of the mixture was formed to 60 liters, and 60 liters of the microorganisms c were prepared assuming that 3 kg was discharged daily in ordinary households. The microorganism c was stored in the tank body 1, and 3 kg of garbage b was put into the tank body 1. Note that the ratio between the microorganism c and the garbage b is preferably approximately 5% to 7%.
Then, the handle 44 as the driving means 14 was rotated three times, and the garbage b and the microorganism c in the tank body 1 were allowed to stand still by being transferred by the transfer means 2, agitated, and mixed.
The next day, when the inside of the tank main body 1 was observed, it was confirmed that 90% of the raw garbage b was decomposed, and the garbage b disappeared inside the tank main body 1 by visual inspection, so-called volume reduction. Was done.
Therefore, 3 kg of fresh garbage b discharged on the day was put into the tank body 1, the driving means 14 was operated, and the feed blade 12 was rotated three times to stand still.
[0079]
In this way, the charging of 3 Kg of the garbage b and the operation of the transfer means 2 by the driving means 14 were repeated every day for 30 days, and as a result, 3 Kg × 30 days = 90 Kg was completely decomposed, and the tank body 1 Inside, the total volume of the substance remaining in the tank body 1 was 65 liters, and although the amount was slightly increased as compared with 63 liters before the start of the treatment, most of them were in the form of powder and granules. The odor emitted from these substances was slightly odorous, but did not emit enough odor to affect daily life.
In the last 30 days, bones and shells of fish, birds, pigs and the like were also ground together with garbage c after being crushed as finely as possible, and finally remained in a lump in this period. However, by extending the treatment period a little more, all of them could be decomposed.
[0080]
Further, as the garbage disposal on the 31st day, it is conceivable to take out all the contents in the tank body 1 and perform a new treatment containing new microorganisms c. Still has sufficient decomposition treatment capacity, and it is best to take out a part (for example, half) of the remaining substance in the tank body 1 and replenish the microorganisms c to the initial 60 liters. I think that the. Half of the remaining substance taken out from the tank body 1 could be used as it is as a fertilizer, for example, as a fertilizer for home gardens, garden trees, flowers and the like.
[0081]
