[0002] The cowshed sewage treatment system involves multiple links, such as sewage collection, solid-liquid separation, flocculation sedimentation, disinfection and discharge, etc., aiming to effectively manage and treat manure and wastewater generated during the breeding process. Proper sewage treatment can reduce the pollution pressure on the environment, protect the quality of soil, water sources and air, and also help improve the utilization efficiency of water resources and reduce the operating costs of the farm. The sewage treatment process also includes the dosing process of flocculants.

[0003] In the prior art, the flocculant dosing device and related solutions used in the cowshed sewage treatment process directly add the proportioned flocculant solution into the treatment tank and let it stand for a period of time. However, the direct addition will result in the liquid being unable to diffuse quickly, and it is necessary to build a stirring device to promote the diffusion of the solution, thereby increasing the equipment cost. At the same time, organic flocculants are usually powdered or solid block substances, which need to be diluted with clean water before being added. Therefore, manual mixing is required when adding the drug. The process has cumbersome operating steps and also requires the use of additional mixing and dilution equipment. Summary of the invention

The cowshed sewage treatment dosing device is used to mix powdered organic flocculant materials with clean water and then dilute them, and then use the agent delivery component 3 to directly contact and mix the diluted and mixed flocculant liquid with the sewage flowing in the injection mechanism 2 to realize the dosing process, and after the dosing is completed, the mixing process is realized in the subsequent flow process of the liquid and the sewage.

[0035] In this embodiment, a guide plate 7 is provided on the outside of the injection mechanism 2, a partition plate 10 is welded on the inside of the injection mechanism 2, a diverter plate 6 is welded on the bottom end of the sewage injection port 5, the water injection pipe 13 is embedded in the surface of the diverter plate 7, the reagent tank 9 is opened in the middle of the two sewage tanks 8, the sewage tank 8 is opened between the partition plate 10 and the guide plate 7, the reagent tank 9 is opened between the two partition plates 10, the reagent tank 9 is separated from the inside of the sewage injection port 5 by the diverter plate 6, and the bottom of the diverter plate 6 is provided with a notch on both sides, and the inside of the sewage tank 8 is connected to the inside of the sewage injection port 5 through the notch at the bottom of the diverter plate 6. The powdered flocculant and clean water are injected and mixed in the reagent delivery component 3, and the reagent delivery component 3 is placed on the top of the injection mechanism 2, so that the stirring component 18 inside the reagent delivery component 3 can be rotated by the sewage in the flowing state, and the mixing and dilution process of the powdered flocculant is automatically realized, which reduces the equipment cost.

[0036] Specifically, sewage flows in from the sewage injection port 5 at the top, and at the bottom diverter plate 6 of the sewage injection port 5, it will be directly diverted from the notch at the bottom of the diverter plate 6 to the sewage troughs 8 on both sides, and finally flow into the mixing channel 11 at the rear end along the sewage troughs 8. The two sewage troughs 8 are separated from the agent tank 9 in the middle by the partition 10, and the flocculant liquid in the agent delivery component 3 also flows directly into the agent tank 9 after internal mixing, and the flocculant liquid flows along the agent tank 9 into the mixing mechanism 4 at the end, and finally the flocculant liquid in the mixing mechanism 4 can be evenly contacted with the fallen sewage part in the mixing channel 11 to achieve the purpose of mixing.

[0037] In this embodiment, the drug delivery component 3 includes a flocculant storage bin 14, an agitation sleeve 16 and an agitation component 18. The top of the flocculant storage bin 14 is provided with a delivery port 15, the agitation sleeve 16 is welded to the bottom of the flocculant storage bin 14, and one side of the agitation sleeve 16 is provided with an overflow port 17. The agitation component 18 includes a central shaft 19, an agitation plate 24 and an impact plate 27. Both ends of the central shaft 19 are embedded in the inner wall of the guide plate 7 through sleeve bearings 20, and one end of the central shaft 19 is provided with a docking port 21, and the central shaft 19 is connected to the water injection pipe through the docking port 21. 13 parts are connected, the surface of the central shaft 19 is provided with a plurality of water inlet holes 23, the impact plate 27 is fixed to both ends of the surface of the central shaft 19 as a whole, the stirring plate 24 is installed in the middle position of the central shaft 19, the edge of the stirring plate 24 is integrally formed with a fixing block 25, and the end of the fixing block 25 is welded with a toothed ring 26, a connecting hole 30 is provided at the connection between the flocculant storage bin 14 and the stirring sleeve 16, a stirring shaft 28 is inserted on the inner wall of the connecting hole 30, and a driven gear 29 is installed at the end of the stirring shaft 28, and the driven gear 29 and the toothed ring 26 are meshed. After the stirring assembly 18 rotates, the driven gear 29 and the stirring shaft 28 at the top can be synchronously driven to rotate by the rotation of the internal toothed ring 26, and the purpose of rubbing the powdered flocculant can be provided by the rotation of the stirring shaft 28 inside the connecting hole 30, thereby reducing the probability of the flocculant being blocked inside the medicine delivery assembly 3.

[0038] Specifically, after the flocculant powder accumulates inside the flocculant storage bin 14, it will directly fall from the connecting hole 30 at the bottom into the stirring sleeve 16, and the inner stirring assembly 18 will be embedded into the corresponding sewage tank 8 through the impact plates 27 at both ends. As the sewage flows and hits one side of the impact plate 27, the entire impact plate 27 and the central shaft 19 can be directly controlled to rotate, and then the surface stirring plate 24 and the gear ring 26 are driven to rotate through the central shaft 19. The external clean water part flows along the water injection pipe 13 and the inside of the central shaft 19, and finally flows into the stirring sleeve 16 from the water inlet hole 23. At this time, the flocculant and the clean water enter the stirring sleeve 16 at the same time, and with the rotation of the stirring plate 24, the dilution and mixing of the flocculant can be achieved. In the stirring process, the flocculant solution will continuously flow out from the overflow port 17 and enter the reagent tank 9, thereby achieving the effect of automatically mixing and diluting the clean water and flocculant.

[0039] As the gear ring 26 rotates, the driven gear 29 and the stirring shaft 28 at the top will be synchronously driven to rotate, and the powdered flocculant at the connecting hole 30 will be rubbed. The rubbing and vibration effects generated will reduce the probability of the powdered flocculant getting stuck in the connecting hole 30.

[0040] In this embodiment, the mixing mechanism 4 includes a diffusion channel 32 and a mixing inclined plate 34, and a medicine delivery channel 31 is welded at the bottom of the injection mechanism 2. The diffusion channel 32 is connected to the bottom end of the medicine delivery channel 31, and a plurality of connecting pipes 33 are inserted on the side of the diffusion channel 32, and the end of each connecting pipe 33 is inserted into the interior of the mixing inclined plate 34, and the top of the medicine delivery channel 31 is connected to the inner end of the medicine tank 9. Specifically, the flocculant solution flows from the inside of the medicine tank 9 into the inside of the medicine delivery channel 31, and after falling into the diffusion channel 32 at the bottom, it enters the mixing inclined plate 34 along each connecting pipe 33, and continues to flow toward the bottom in a large range inside the mixing inclined plate 34, while the sewage part also flows toward the bottom inside the mixing channel 11, so the flocculant solution will continue to be mixed and injected along the inclined plate toward the falling sewage, so as to achieve a uniform mixing effect, and after the mixing is completed, it can be statically precipitated inside the sedimentation tank 1 at the bottom.

[0041] This embodiment also provides a method for using the above-mentioned dosing device, comprising the following steps:

[0042] Step 1: Fill the flocculant into the inside of the medicine delivery component 3. The flocculant used in this embodiment is a powdered organic flocculant material. When the flocculant is delivered, it directly enters the inside of the flocculant storage bin 14 from the delivery port 15, and falls from the bottom connecting hole 30 to the bottom stirring sleeve 16 for dilution and mixing.

[0043] Step 2: inject the dilution water into the medicine delivery assembly 3 through the water injection pipe 13. The water flows along the water injection pipe 13 and the inside of the central axis 19, and finally flows into the inside of the stirring sleeve 16 from the water inlet hole 23. At this time, the flocculant and the water enter the stirring sleeve 16 at the same time.

[0044] Step 3: The sewage flows along the inside of the injection mechanism 2, and at the bottom of the sewage injection port 5, the sewage will be directly diverted from the notch at the bottom of the diverter plate 6 to the sewage tanks 8 on both sides, and finally flow into the mixing channel 11 at the rear end along the sewage tank 8;

[0045] Step 4: During the flow of sewage inside the injection mechanism 2, the sewage impacts the stirring assembly 18, which is linked to rotate the stirring assembly 18. During the flow of sewage inside the sewage tank 8, the impact plate 27 always provides a unidirectional thrust, which acts on the central shaft 19 to drive the stirring plate 24 to rotate, and the clean water flows into the stirring sleeve 16 through the central shaft 19.

[0046] Step 5: The stirring assembly 18 drives the gear transmission structure inside the stirring sleeve 16 to rotate, so that the flocculant inside the stirring sleeve 16 is fully mixed with the clean water. During the mixing process, the gear ring 26 is synchronously meshed with the driven gear 29 on the top, and the powdered flocculant at the connecting hole 30 can be rubbed by the rotation effect of the driven gear 29 and the stirring shaft 28. The rubbing and vibration effects generated reduce the probability of the powdered flocculant getting stuck in the connecting hole 30.

[0047] Step six, the diluted and mixed flocculant solution flows into the injection mechanism 2, and the flocculant solution flows from the inside of the agent tank 9 into the inside of the agent delivery channel 31, and after falling into the diffusion channel 32 at the bottom, it enters the mixing inclined plate 34 along each connecting pipe 33 respectively. The flocculant solution will continue to be mixed and injected from the side along the inclined plate toward the falling sewage, and finally added to the flowing sewage inside the mixing channel 11. After the addition of the drug, the sewage enters the sedimentation tank 1 for static sedimentation treatment.

[0048] In the method of using the dosing device, the sewage flow provides power to control the rotation of the stirring component 18, so that the powdered flocculant and clean water can be directly diluted and stirred, and the sewage part can also be directly added and injected from the side in the subsequent flow process under synchronous control of the flocculant solution, ensuring that the flocculant solution and the sewage are evenly and quickly mixed in the flowing state.

[0049] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
