Specific Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Reference Figures 1 to 5, a sewage filtration device for coal mines, comprising a frame 1. A rectangular opening 2 is provided on the frame 1. Above the rectangular opening 2, a support frame 3 is fixedly connected. On the front side of the support frame 3, a front baffle 4 is fixedly connected. Behind the front baffle 4, there are several filter plates 5. Behind the filter plates 5, there is a rear baffle 6. The filter plates 5 and the rear baffle 6 are slidably connected to the support frame 3. In the center of the front baffle 4, there is a water inlet 7, and at the four corners, there are water outlets 8. A soft filter screen 9 is detachably connected to the filter plate 5. In the center of the filter plate 5, there is a through hole 10. The water inlet 7 is communicated with the through hole 10. The inner side of the rear baffle 6 is a concave structure. The rear baffle 6 is fixedly connected to a hydraulic cylinder 11, and the hydraulic cylinder 11 is fixedly connected above the frame 1.

[0020] On the support frame 3, there is a slide rail 12. On both sides of the filter plate 5 and the rear baffle 6, there are handles 13. Below the handles 13, there are grooves 14, and the grooves 14 are slidably connected to the slide rail 12. At the rear end of the slide rail 12, there is a fixing plate 15.

[0021] Below the frame 1, a collection tank 16 is fixedly connected. The collection tank 16 is installed directly below the filter plate 5. The collection tank 16 is in the shape of a horn with openings at both the top and the bottom.

[0022] Inside the collection tank 16, a central shaft 17 is installed through bearings. On the central shaft 17, a spiral plate 18 is fixedly connected. One end of the central shaft 17 is drivingly connected to a motor 19.

[0023] On both sides below the frame 1, a crawler chassis 20 is installed. The crawler chassis 20 is drivingly connected to a hydraulic motor 21. A hydraulic pump 22 provides power for the hydraulic motor 21, and the hydraulic pump 22 is fixedly connected to the frame 1.

[0024] On the frame 1, there is also an electromagnetic starter 23 and an operating console 24. On the operating console 24, there are a control valve 25 and a pressure gauge 26.

[0025] Working principle: During operation, turn on the electromagnetic starter 23. Control the crawler chassis 20 to drive to the operation area through the operating console 24. Install the soft filter screen 9 on the filter plate 5. Then, control the hydraulic cylinder 11 to extend through the operating console 24, pushing the rear baffle 6 to slide forward, so that the rear baffle 6 is closely attached to several filter plates 5. The solid-liquid mixed water in the mine enters through the water inlet 7 on the front baffle 4, passes through the through hole 10 in the center of the filter plate 5, reaches the concave area of the rear baffle 6, and then starts to pass through the filtering area from the concave area of the rear baffle 6. The soft filter screen 9 intercepts the solid impurities. The purified water flows out through the water outlet 8 on the front baffle 4 for collection and use. When there are too many impurities on the soft filter screen 9, control the hydraulic cylinder 11 to contract through the operating console 24, separating the rear baffle 6 from the filter plate 5, and gaps are also generated between the filter plates 5. At this time, shake the soft filter screen 9 to shake the impurities into the collection tank 16. Through the operation of the operating console 24, rotate the spiral plate 18 to convey the impurities in the collection tank 16 out.

[0026] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
