The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

An apparatus for preparing a liquid flocculant according to an embodiment of the present invention is described below with reference to fig. 1 to 5.

The liquid flocculant preparation device according to the embodiment of the invention comprises a feed box 100, a preparation box 200, a storage box 300 and a throwing system 400 which are sequentially connected, wherein the feed box 100 holds flocculant raw materials, a mixing cylinder 210 for mixing liquid flocculant and water is arranged at the upper part of the preparation box 200, the mixing cylinder 210 is communicated with the feed box 100 through a first pipeline 110 and adds flocculant into the mixing cylinder 210 through a first pump 120, the mixing cylinder 210 is communicated with the preparation box 200 so as to output the mixed flocculant into the preparation box 200, the storage box 300 is communicated with the preparation box 200 through a second pipeline 310, the feed box 100 and the preparation box 200 are arranged above the storage box 300, the storage box 300 is communicated with the bottom end of the preparation box 200 through a second pipeline 310, the feed box 100 and the preparation box 200 are arranged above the storage box 300, and the throwing system 400 is communicated with the storage box 300 and pumps the flocculant in the storage box 300 through a third pump so as to mix the flocculant with water and throw the flocculant.

It will be appreciated that existing flocculant preparation devices typically do not employ pumps for material transport due to the solid dry powder of the raw material. While first pump 120 is typically delivered using a diaphragm pump, the diaphragm pump has low shear forces and low physical impact on the material, as compared to other types of pumps, and is particularly useful for flocculant transport.

For example, referring to fig. 1, both the bin 100 and the preparation tank 200 are disposed at the top of the storage tank 300, and as shown in fig. 3, the bin 100 is disposed at the lower left corner of the upper surface of the storage tank 300, and the preparation tank 200 is disposed at the right half of the upper surface of the storage tank 300. The first pipe 110 is connected from the top of the tank 100 to the top of the preparation tank 200, and the first pump 120 on the first pipe 110 is fixed at a position where the preparation tank 200 interfaces with the tank 100. In general, the preparation tank 200 is further provided with a support member for supporting the first pipe 110, preventing the first pipe 110 from being deformed by its own weight. The storage tank 300 is communicated with the preparation tank 200 through a second pipe 310, and in order to save space, the second pipe 310 is arranged at the upper left corner of the top of the storage tank 300, one end of the second pipe is connected with the lower part in the preparation tank 200, the other end of the second pipe is connected with the top of the storage tank 300, and the flocculant prepared in the preparation tank 200 can be transferred to the storage tank 300 for storage. It will be appreciated that the second conduit 310 is provided with a valve for controlling the on-off of the second conduit, thereby better controlling the flow of liquid. The delivery system 400 is disposed at a side of the storage tank 300, and pumps and delivers the flocculant in the storage tank 300 by the second pump 410.

According to some embodiments of the present invention, an overflow cylinder 220 is disposed in the mixing cylinder 210, a first water filling port 230 is disposed at a side wall of the mixing cylinder 210, an outlet of the first pipe 110 is disposed between the overflow cylinder 220 and the mixing cylinder 210, an upper end of the overflow cylinder 220 is higher than a bottom surface of the mixing cylinder 210, and the flocculant mixed in the mixing cylinder 210 flows out of the overflow cylinder 220. For example, referring to fig. 2, the outlet of the first pipe 110 is vertically downward, so that the flocculant can flow out after being mixed between the overflow cylinder 220 and the mixing cylinder 210, the flocculant is prevented from directly flowing out of the overflow cylinder 220, and water and the flocculant need to enter the overflow cylinder 220 from the top of the overflow cylinder 220 after being mixed, in other words, the flocculant and the water mixed in the mixing cylinder 210 need to reach a certain amount before being delivered into the preparation tank 200, so that the flocculant and the water can be fully mixed, the mixing precision can be controlled better, and concentration deviation can be avoided.

According to some embodiments of the present invention, the first water filling port 230 fills water into the mixing drum 210 in a tangential direction of the overflow drum 220. The first water filling port 230 is filled from a horizontal tangential direction, and a rotational flow is formed by water flow filled from the tangential direction, so that water and a flocculating agent are more fully mixed, and the mixing effect is better.

According to some embodiments of the present invention, both the outlet of the first conduit 110 and the first water filling port 230 are positioned below the height of the overflow drum 220. For example, referring to fig. 3, in order to prevent water and flocculant from being splashed out of the overflow cylinder 220 without being mixed, both the outlet of the first pipe 110 and the first water filling port 230 are lower than the upper end of the overflow cylinder 220. When the mixing cylinder 210 is used for mixing, liquid is always remained between the outer wall of the overflow cylinder 220 and the mixing cylinder 210, so that the outlet of the first pipeline 110 and the first water filling port 230 are directly communicated with liquid, splashing of the liquid is avoided, and mixing precision is ensured.

According to some embodiments of the present invention, a mixing bucket 240 and a water injection barrel 290 sleeved outside the mixing bucket are connected below the overflow barrel 220, a closed water injection cavity 250 is formed between the mixing bucket 240 and the water injection barrel 290, the inside of the mixing bucket 240 is communicated with the overflow barrel 220 to receive the flocculant flowing down from the overflow barrel 220, a plurality of injection holes 260 are formed on the inclined surface of the mixing bucket 240, and a second water injection port 270 is formed in the water injection cavity 250. For example, referring to fig. 3, a mixing bucket 240 is connected below the overflow cylinder 220, and the mixing bucket 240 is placed with a small upper opening and a large lower opening. A closed water injection cavity 250 is formed between the mixing hopper 240 and the water injection barrel 290, a plurality of injection holes 260 are formed in the inclined surface of the mixing hopper 240, the injection holes 260 are uniformly distributed around the central axis of the mixing hopper 240, and the water injection cavity 250 is provided with a second water injection port 270. The second water filling port 270 fills the water filling chamber 250, and when water in the water filling chamber 250 is filled into the mixing bucket 240 through the filling hole 260. The upper opening of the mixing bucket 240 is communicated with the overflow cylinder 220, and after the water and the flocculating agent are mixed and diluted for the first time in the overflow cylinder 220, the water and the flocculating agent flow into the mixing bucket 240, and then are mixed and diluted for the second time with the water injected through the injection hole 260, and finally the required flocculating agent is obtained and flows into the preparation box 200.

It will be appreciated that overflow cartridge 220 and mixing bucket 240 may be integrally designed, but the middle needs to be blocked to separate mixing cartridge 210 into upper and lower chambers, such as in FIG. 3, where flocculant and water flow from the upper port of overflow cartridge 220 after mixing in the upper half of mixing cartridge 210. In the lower half of the mixing drum 210, the water injection chamber 250 is filled with water and does not directly contact the flocculant mixture in the upper half but merges with the flocculant flowing down from the overflow drum 220 through the injection hole 260.

According to some embodiments of the invention, the end of the first pipe 110 connected to the tank 100 extends into the lowest part of the tank 100 and is provided with a filter check valve. For example, referring to fig. 1, one end of the first pipe 110 disposed in the tank 100 is extended into the bottom of the tank 100 to ensure that the lowest material of the tank 100 can be withdrawn, the filter check valve can filter impurities, prevent impurities in the flocculant raw material from entering the preparation process, and simultaneously the filter check valve can prevent backflow, thereby facilitating high-precision control.

According to some embodiments of the present invention, the first pipe 110 is provided with a downward injection valve at one end inside the mixing drum 210, for example, referring to fig. 2, since the first pipe 110 is immersed in the liquid at one end inside the mixing drum 210 for a long period of time, the injection valve needs to be provided to prevent the liquid from flowing back, so that the concentration of the liquid in the tank 100 is not affected, and the injection valve can perform better precision control.

According to some embodiments of the present invention, the stirring device 280 is disposed in the preparation tank 200, for example, referring to fig. 4, the stirring device 280 is mainly a stirring rod driven by a motor, so as to stir the flocculant in the preparation tank 200, prevent the flocculant from depositing to cause uneven concentration, and further promote the mixing of the flocculant and water.

According to some embodiments of the present invention, the second pump 410 is a screw pump, for example, referring to fig. 5, the delivery system 400 is in communication with the storage tank 300 through the second pump 410, and the screw pump has a wider flow channel, so that the transportation effect is better.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
