Description

Technical Field

[0001] This utility model relates to the field of water pollution control technology, and in particular to a filtration device for water pollution control. Background Technology

[0002] In recent years, in vast rural areas of China, large amounts of untreated sewage have been directly discharged into rivers and ponds, far exceeding the environment's capacity for self-purification. This has severely polluted the aquatic environment and affected the quality of life of villagers. In the process of decentralized sewage treatment in rural areas, some households need to treat their sewage together. The sewage treatment equipment has a relatively long collection pipeline network, and gravity drainage may cause the sewage treatment equipment to have poor drainage. Therefore, lift pumps are often used to transport sewage.

[0003] Currently, when using booster pumps for sewage treatment, the pump inlet is often blocked by debris, preventing effective filtration and affecting the pump's performance. This also necessitates manual cleaning, indirectly increasing labor costs and impacting the efficiency of water pollution control. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in existing sewage treatment using booster pumps, the inlet of the booster pump is often blocked by debris, which prevents effective filtration, affects the performance of the booster pump, and requires manual cleaning, indirectly increasing labor costs and affecting the efficiency of water pollution control. Therefore, this invention proposes a filtration device for water pollution prevention and control.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A filtration device for water pollution control includes a booster pump body, an equalization tank, and an anaerobic tank. A retaining ring is fixedly fitted on the outer circumference of the booster pump body, and multiple support legs are fixedly connected to the bottom of the retaining ring. Multiple water inlet holes are provided at the bottom of the booster pump body. A rotating shaft is rotatably inserted into the inner bottom wall of the booster pump body. Multiple impellers are fixedly connected to the top of the rotating shaft, and two rotating brackets are fixedly connected to the bottom of the rotating shaft. A mounting base is fixedly connected to the other end of the rotating brackets. A cleaning brush is fixedly connected to one side of the mounting base, and the cleaning brush moves on the outside of the water inlet holes of the booster pump body.

[0007] Furthermore, a filter screen is fixedly connected between every two of the support legs.

[0008] Furthermore, the rotating shaft is rotatably connected to the bottom of the lifting pump body via a bearing.

[0009] Furthermore, a water outlet pipe is inserted into the top of the booster pump body.

[0010] Furthermore, the booster pump body is installed inside the regulating tank.

[0011] Furthermore, one end of the outlet pipe extends into the anaerobic tank.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The impeller rotates under the scouring of the water flow, which in turn drives the rotating shaft to rotate, which in turn drives the rotating bracket to rotate. This causes the cleaning brush to brush against the outside of the water inlet, thereby removing debris from the water inlet and ensuring effective filtration of sewage.

[0014] 2. The support legs can support the pump body, thereby preventing the bottom of the pump body from contacting the bottom inner wall of the equalization tank, so as to prevent sludge from affecting the use of the pump body. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4A filtration device for water pollution control includes a lift pump body 1, an equalization tank 12, and an anaerobic tank 13. A retaining ring 2 is fixedly fitted on the outer circumference of the lift pump body 1. Multiple support legs 3 are fixed to the bottom of the retaining ring 2 by bolts, thereby supporting the lift pump body 1 and preventing the bottom of the lift pump body 1 from contacting the bottom inner wall of the equalization tank 12, so as to prevent sludge from affecting the use of the lift pump body 1. A filter screen 4 is fixed between every two support legs 3 by bolts, thereby performing preliminary filtration of sewage. Multiple water inlet holes 5 are provided at the bottom of the circumference of the lift pump body 1. A water outlet pipe 11 is inserted into the top of the lift pump body 1. Sewage flows into the lift pump body 1 from the water inlet holes 5 and then flows out into the anaerobic tank 13 from the water outlet pipe 11.

[0022] A rotating shaft 7 is rotatably inserted into the bottom inner wall of the booster pump body 1. Multiple impellers 6 are welded to the top of the rotating shaft 7, and two rotating brackets 8 are welded to the bottom of the rotating shaft 7. The other end of the rotating bracket 8 is fixed with a mounting base 9 by bolts. A cleaning brush 10 is fixed to one side of the mounting base 9 by bolts. The cleaning brush 10 brushes on the outside of the water inlet hole 5 of the booster pump body 1. Under the flushing of the water flow, the impellers 6 are driven to rotate, which in turn drives the rotating shaft 7 to rotate, and then drives the rotating bracket 8 to rotate. Thus, the cleaning brush 10 brushes on the outside of the water inlet hole 5, thereby removing debris from the water inlet hole 5.

[0023] The rotating shaft 7 is rotatably connected to the bottom of the lift pump body 1 through a bearing, which makes the rotating shaft 7 rotate more smoothly. The lift pump body 1 is set in the equalization tank 12, and one end of the outlet pipe 11 extends into the anaerobic tank 13.

[0024] The working principle of this embodiment is as follows: In use, firstly, the lift pump body 1 is placed in the regulating tank 12 and supported by the support legs 3. Then, after the sewage is initially filtered by the filter screen 4, it flows into the lift pump body 1 through the inlet hole 5 and then flows out through the outlet pipe 11 into the anaerobic tank 13. Under the flushing of the water flow, the impeller 6 is driven to rotate, which in turn drives the rotating shaft 7 to rotate, and then drives the rotating bracket 8 to rotate. As a result, the cleaning brush 10 brushes on the outside of the inlet hole 5, thereby removing the debris in the inlet hole 5.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
