[0034] Furthermore, a cover plate 11 is movably connected to the upper part of the outer shell 1 for fitting the outer shell 1. A water inlet pipe 12 is fixedly connected to the middle of the cover plate 11 for introducing coal mine sewage. A discharge port 13 is opened on both the left and right sides of the lower part of the outer shell 1 for discharging impurities. A sliding groove 14 is opened on both the front and rear sides and the left and right sides of the inner wall of the outer shell 1 for fitting the installation of the filter element 3.

[0035] like Figure 4 As shown, the filter element 3 includes a horizontal plate 31, and inclined plates 32 are provided on both the left and right sides of the horizontal plate 31. Both the horizontal plate 31 and the inclined plates 32 are filter plates. One end of the inclined plate 32 is fixedly connected to the horizontal plate 31 to assist in filtering impurities and to guide the impurities through the discharge port 13 to the guide plate 5. The other end of the inclined plate 32 is fixedly connected to a locking rod 33 for installation with the mounting rod 7. The locking rod 33 is movably connected to the mounting rod 7. Sliding rods 34 are fixedly connected to the front and rear sides and the left and right sides of the horizontal plate 31 for connection with the outer shell 1. The sliding rods 34 are slidably connected to the sliding groove 14. The upper part of the two sliding rods 34 on the same side of the front and rear sides, near the cleaning element 4, is fixedly connected to a pull rod 35 to facilitate the removal and installation of the filter element 3.

[0036] Please see Figure 5 - Figure 6The cleaning piece 4 comprises a cleaning piece 41 for cleaning the impurities on the horizontal plate 31, preventing the impurities from piling up and blocking the filter plate, and assisting in discharging the impurities. The lower part of the cleaning piece 41 is provided with a connecting rod 43 for connecting the cleaning piece 41 and the blade 42. The lower part of the connecting rod 43 is fixedly connected with the blade 42, which can be driven to rotate by the water flow. The cleaning piece 41 comprises a round block 411 for connecting various components. The bottom of the round block 411 is fixedly connected with a connecting block 412 which penetrates through the horizontal plate 31 and is movably connected with the horizontal plate 31. The connecting block 412 is used for connecting with the mounting block 413. The lower part of the connecting block 412 is screwedly connected with the mounting block 413 for connecting with the connecting block 412 to connect the cleaning piece 41 and the horizontal plate 31.

The left and right sides of the round block 411 are fixedly connected with cleaning brushes 414 for cleaning the impurities on the horizontal plate 31.

[0037] Working principle: when in use, the coal mine sewage enters the shell 1 through the water inlet pipe 12. The impurities in the coal mine sewage are filtered by the horizontal plate 31. The filtered water flows downward into the water guide frame 6. The water guide frame 6 guides the water to the blade 42. Under the impact of the water flow, the blade 42 rotates, and the connecting rod 43 connected with the blade 42 drives the cleaning piece 41 to rotate, thereby pushing the impurities accumulated on the horizontal plate 31 to the inclined plate 32. The inclined plate 32 guides the impurities to the guide plate 5 and discharges the equipment. At the same time, the water mixed in the material is filtered again through the inclined plate 32 and the guide plate 5. The water filtered through the horizontal plate 31, the inclined plate 32 and the guide plate 5 flows into the water collecting tank 2 and is finally discharged through the drain pipe 21.

[0038] When the filter piece 3 or the cleaning piece 41 needs to be replaced, the cover plate 11 is opened, and then the pull rod 35 is pulled to drive the overall filter piece 3 and the cleaning piece 41 to separate from the shell 1 through the slide rod 34. Then one hand holds the connecting rod 43 and the other hand twists the round block 411 to drive the connecting block 412 and the mounting block 413 to separate, so as to remove the cleaning brush 414. The filter plate or the cleaning brush 414 can be replaced. After the replacement is completed, the cleaning piece 4 and the horizontal plate 31 are installed together. Then the slide rod 34 is aligned with the slide groove 14, and the filter piece 3 is installed in the shell 1 again. The clamping rod 33 is clamped into the mounting rod 7.

[0039] Finally, it should be pointed out that the above-described preferred embodiments of the present application are not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
