This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for hydraulic engineering. It includes a bearing seat located at the top of a treatment tank, with a main rod rotatably connected to the bearing seat towards the center of the tank's interior. The outer wall of the treatment tank is fitted with a sandwich layer, the inner wall of which, together with the outer wall of the treatment tank, forms a separation cavity. As the wastewater treatment time increases, the amount of agglomerates generated inside the interceptor plate gradually increases. In the centrifugal force field generated by the stirring assembly, the larger the agglomerate, the easier it is to move away from the axis of the main rod. Simultaneously, driven by blades at different heights, the agglomerates rise along the inclined surface of the inner wall of the interceptor plate. The rising liquid then carries larger agglomerates that reach the height of the fixed arm, which, through overflow, follow a small amount of wastewater through the separation hole into the separation cavity and fall to the cleaning hole, thus facilitating the cleaning of the agglomerates while continuously treating wastewater.

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the prior art, the filter holes on the interception plate are axially distributed along the treatment chamber, the impact force of water flow on the filter holes along the axial direction of the treatment chamber is not stable, and the filter holes are easily blocked along with the gradual increase of the agglomerates. And when the treatment demand of sewage increases, for example, sewage from water works such as reservoirs, rivers, etc., each treatment period requires cleaning of the treatment chamber, particularly, agglomeration of clogging in the filter pores, resulting in a decrease in the purification efficiency of sewage.
Referring to fig. 1-3, in order to solve the above-mentioned problems existing in the prior art, an object of the present invention is to provide a sewage treatment device for hydraulic engineering, the sewage treatment device includes a bearing block 103 disposed at the top of a treatment tank 100, and the bearing block 103 is rotatably connected with a main rod 110 toward an axis inside the treatment tank 100;
The outer wall of the treatment tank 100 is sleeved with an interlayer 130, the inner wall of the interlayer 130 and the outer wall of the treatment tank 100 enclose a separation cavity, the upper part of the separation cavity is communicated with the inside of the treatment tank 100, and the lower part of the separation cavity is communicated with the outside;

the end of the stirring assembly 200, which is far away from the main rod 110, is adapted to the shape of the inner side wall of the interception plate 120, the inner edge and the outer edge of the interception plate 120 are radially communicated with each other in the treatment tank 100, the radius of the interception plate 120 is gradually narrowed from high to low, and the stirring assembly 200 is used for driving the aggregate formed by the flocculating agent and the impurities to rise along the inner side wall of the interception plate 120 and overflow into the separation cavity.
In practice, firstly, sewage from hydraulic engineering is put into the treatment tank 100 through the sewage inlet 101 at the top of the treatment tank 100, and a flocculating agent is put into the sewage in the treatment tank 100 through the dosing assembly 300, the flocculating agent and impurities in the sewage are combined to form an aggregate, the aggregate is intercepted by the interception plate 120, and the purified water passes through the interception plate 120 and flows out from the purified water outlet 102.
As the time for treating sewage increases, the amount of the agglomerates generated inside the interception plate 120 gradually increases, and in the centrifugal force field generated by the stirring of the stirring element 200, the larger the weight of the agglomerates, i.e., the greater the density/mass, the more easily the agglomerates move in a direction away from the axis of the main shaft 110. Meanwhile, the liquid level stirred by the stirring assembly 200 presents the phenomenon of low center and high edge, so that the aggregate at the position far away from the main rod 110 gradually rises along the inner side wall of the interception plate 120, overflows into the separation cavity along with the liquid level with raised edge, realizes automatic cleaning of the aggregate generated at the inner side of the interception plate 120, avoids the phenomenon that the whole device is required to be closed for cleaning the filtering mechanism when sewage is treated for a period of time like the existing sewage treatment mechanism, and is particularly suitable for treating sewage with large treatment capacity from hydraulic engineering.
Moreover, since the inner side and the outer side of the interception plate 120 are communicated in the radial direction, the strong radial flow generated when the stirring assembly 200 stirs sewage at a high speed can dredge the communication parts of the inner side and the outer side of the interception plate 120, and prevent the communication parts from being blocked by the agglomerates so as to influence the sewage purification treatment efficiency.
For the convenience of understanding the above, referring to fig. 4, a process of adding a flocculant to the chemical dosing assembly 300 is disclosed, an inner sidewall of the treatment tank 100 is fixedly connected with a circular ring mounting plate, a top of the circular ring mounting plate is fixedly connected with a guide rail 310, a top of the guide rail 310 is slidably connected with a sliding seat 320, a medicine storage cavity 350 is arranged on one side of the sliding seat 320 close to an axis of the treatment tank 100, and the medicine storage cavity 350 is used for sowing the flocculant into sewage.
Further, a plurality of pulleys 330 are rotatably connected to the sliding seat 320, the plurality of pulleys 330 are respectively attached to the outer wall of the guide rail 310, and the rotation of the pulleys 330 is driven by a motor.
Moreover, a limiting plate 340 is arranged between the sliding seat 320 and the medicine storage cavity 350, the limiting plate 340 is fixedly connected with the sliding seat 320, the medicine storage cavity 350 is slidably connected to one side, far away from the sliding seat 320, of the limiting plate 340, and the medicine storage cavity 350 is parallel to a tangent line of the sliding seat 320, where the guide rail 310 is located, at any moment along a sliding track of the limiting plate 340.
In the present embodiment, the shape of the guide rail 310 is circular to adapt to the shape of the interior of the treatment tank 100, and may be changed according to the actual shape of the treatment tank 100 in actual use, for example, circular rectangular.
After sewage is introduced into the treatment tank 100, the power supply of the motor connected with the pulley 330 is connected, the pulley 330 starts to rotate under the drive of the motor, and friction exists between the pulley 330 and the outer wall of the guide rail 310, and the friction is the driving force for driving the sliding seat 320 to rotate along the track of the guide rail 310. Meanwhile, the medicine storage chamber 350 moves along the track of the guide rail 310 following the slide holder 320, and during the movement, the moving speed of the slide holder 320 is changed by changing the rotating speed of the motor, thereby realizing the discharging of the flocculant stored in the medicine storage chamber 350. For example, by braking or accelerating the sliding seat 320, the medicine storage chamber 350 slides along the tangential direction of the sliding seat 320 under the action of inertia force, so that the flocculant in the medicine storage chamber 350 is shaken off into the sewage.
Next, as shown in fig. 5 and 6, the stirring assembly 200 includes a plurality of mounting seats 210 fixedly connected to the main rod 110 coaxially, the mounting seats 210 are distributed at intervals along the axial direction of the main rod 110, and a plurality of paddles 220 are fixedly connected to each mounting seat 210 in the radial direction.
The length of each blade 220 is gradually shortened from top to bottom to adapt to the shape of the inner sidewall of the interception plate 120, and the angle between the blade 220 and the horizontal plane is an acute angle for driving the agglomerate to rise along the inclined surface of the blade 220.
On the basis of the above, the paddles 220 with different heights are staggered with each other on the horizontal projection plane, and the paddles 220 positioned above are used for driving the agglomerates lifted by the lower part of the paddles to continue upwards along the rotation direction of the paddles 220.
That is, when the main lever 110 is driven by the motor to drive each blade 220 to rotate, the blade 220 positioned at the lowest position is marked as the inclined plane of the first driving blade to drive the aggregate to move upwards, the blade 220 positioned above and at the upstream side of the first driving blade is marked as the inclined plane of the second driving blade to replace the first driving blade, and the lifted aggregate is driven to continuously rise, so that the blade 220 one by one drives the aggregate to rise along the inclined plane of the inner side of the interception plate 120 until the aggregate overflows into the separation cavity under the action of rising of the liquid level at the edge of the sewage, and the separation of the aggregate in the sewage is realized on the premise of not closing the whole device, thereby improving the treatment efficiency of the sewage.
Based on the above description, the following explanation is made with reference to fig. 7 to 9 on the preferred effect of the interception plate 120 in this embodiment, in which a plurality of filtering holes 121 are formed on the sidewall of the interception plate 120 along the radial direction, for bearing the radial flow of the blade 220 to realize the dredging of the inside of the filtering holes 121, the top of the interception plate 120 is fixedly connected with a fixing arm 122, and the outer wall of the fixing arm 122 is fixedly connected with the inner wall of the treatment tank 100.
Then, the end of the blade 220 remote from the main lever 110 is fitted to the inclined surface of the sidewall of the interception plate 120, and the end of the blade 220 remote from the main lever 110 is adjacent to the inner sidewall of the interception plate 120.
The upper part of the treatment tank 100 is provided with a plurality of separation holes 131 for communicating the treatment tank 100 with the separation chamber, and the bottom of the interlayer 130 is provided with a plurality of cleaning holes 132 for communicating the separation chamber with the outside.
It should be noted that, since the filter holes 121 are distributed along the radial direction of the interception plate 120, the strong radial force generated when the blades 220 stir the sewage at a high speed may generate an impact force on the aggregates deposited in the filter holes 121, thereby realizing the dredging of the filter holes 121.
In addition, when the paddle 220 rotates at a high speed, the sewage and the aggregate therein are driven to perform circular motion together, and at this time, the aggregate is subjected to two key forces:
centrifugal force, namely direction deviating from the axis of the blade 220, and the calculation formula is F=m R, where m is the mass of the agglomerate, ω is the angular velocity and r is the radius of rotation. The larger the weight of the agglomerate, the larger the centrifugal force, and the easier the viscous resistance of the sewage is overcome, and the agglomerate moves to an outer area far from the axis. The viscous drag, which is generated by the friction of the sewage on the aggregate and is directed to the axis of the blade 220, is related to the movement speed and the particle size of the aggregate.
The aggregate with large weight has centrifugal force far larger than viscous resistance and can quickly migrate outwards, and the micro aggregate or impurities with small weight has insufficient centrifugal force to overcome resistance and can move along with sewage in the area close to the axis, so that the grading separation of the light and heavy aggregate is realized.
The weight-increased aggregate gradually moves towards the direction close to the side wall of the interception plate 120, and simultaneously, the aggregate rises along the inclined plane of the inner wall of the interception plate 120 under the driving of the paddles 220 with different heights, and due to the phenomenon of liquid revolution paraboloid driven by centrifugal force, when the paddles 220 rotate, sewage is driven to do circular motion, and liquid particles are subjected to the action of centrifugal force, and the direction of the liquid particles deviates from the axis of the paddles 220, namely, the liquid particles point to the side wall of the main rod 110. The centrifugal force pushes the liquid to migrate toward the side wall of the main rod 110, and the liquid level rises due to accumulation of the liquid near the side wall of the main rod 110.
Thus, the ascending liquid drives the larger aggregate reaching the height position of the fixed arm 122, and a small amount of sewage passes through the separation hole 131 to reach the separation cavity under the overflow action, and falls to the cleaning hole 132 to clean the aggregate on the premise of continuously treating the sewage.
The working principle of the sewage treatment device is described in detail below:
Firstly, sewage from hydraulic engineering is put into the treatment tank 100 through a sewage inlet 101 at the top of the treatment tank 100, and a flocculating agent is put into the sewage in the treatment tank 100 through a dosing assembly 300, the flocculating agent and impurities in the sewage are combined to form an aggregate, the aggregate is intercepted by an interception plate 120, and purified water passes through the interception plate 120 and flows out of a purified water outlet 102.
As the time for treating sewage increases, the amount of the agglomerates generated inside the interception plate 120 gradually increases, and in the centrifugal force field generated by the stirring of the stirring element 200, the larger the weight of the agglomerates, i.e., the greater the density/mass, the more easily the agglomerates move in a direction away from the axis of the main shaft 110. Meanwhile, the liquid surface stirred by the stirring assembly 200 presents a phenomenon of low center and high edge, so that the aggregate with increased weight gradually moves towards the direction close to the side wall of the interception plate 120, and simultaneously, the aggregate rises along the inclined surface of the inner wall of the interception plate 120 under the driving of the paddles 220 with different heights, and the liquid particles are subjected to the centrifugal force action under the action of the circular motion of sewage driven by the paddles 220 when the paddles 220 rotate due to the liquid rotating paraboloid phenomenon driven by the centrifugal force, wherein the direction of the liquid particles deviates from the axis of the paddles 220, namely, the liquid particles are directed towards the side wall of the main rod 110. The centrifugal force pushes the liquid to migrate toward the side wall of the main rod 110, and the liquid level rises due to accumulation of the liquid near the side wall of the main rod 110.
Thus, the ascending liquid drives the larger aggregate reaching the height position of the fixed arm 122, and a small amount of sewage passes through the separation hole 131 to reach the separation cavity and falls to the cleaning hole 132 under the overflow action, so that the cleaning of the aggregate is realized on the premise of continuously treating the sewage.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present invention, and are not intended to limit the invention, and that various changes and modifications may be made therein without departing from the spirit and scope of the invention as claimed.
