DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following is a further detailed description of the present application in combination with the attached Figures 1-4 to further illustrate the present application.

[0020] An embodiment of the present application discloses a sewage sedimentation and filtration device, referring to Figure 1, including a filtration tank 1 that can filter sewage. At the upper end of the filtration tank 1, there is a mixing tank 2 that can mix the sewage. The inner wall of the mixing tank 2 is rotatably connected to a rotating shaft 3. At the upper end of the mixing tank 2, a first motor 4 is fixedly connected. The output end of the first motor 4 is fixedly connected to the rotating shaft 3. A plurality of stirring fan blades 5 are fixedly connected to the outer wall of the rotating shaft 3. The rotation of the rotating shaft 3 can drive the stirring fan blades 5 to stir and mix the sewage inside the mixing tank 2. The inner wall of the filtration tank 1 is provided with a filter plate 7 that can filter the mixed sewage. At the lower end of the filter plate 7, two mounting brackets 8 are fixedly connected. On the inner wall of the filtration tank 1, two fixing plates 9 are fixedly connected. Two sliding rods 10 are slidably connected to the body of the fixing plates 9. The upper ends of the sliding rods 10 are fixedly connected to the mounting brackets 8. At the lower ends of the two sliding rods 10, a bottom plate 11 is fixedly connected. Two springs 12 are fixedly connected to the upper end of the bottom plate 11, which can make the bottom plate 11 fit on the surface of the cam 14. The upper ends of the springs 12 are fixedly connected to the fixing plates 9. The filtration tank 1 is provided with a jitter component that can drive the filter plate 7 to jitter up and down;

[0021] Specifically, referring to Figure 4 , the jitter component includes a rotating rod 13, a cam 14, and a second motor 15. The inner walls of the filtration tank 1 are rotatably connected to the two rotating rods 13. The rod bodies of the rotating rods 13 are fixedly connected to the two cams 14. On the outer wall of one side of the filtration tank 1, the second motor 15 is fixedly connected. The output end of the second motor 15 is fixedly connected to the rotating rod 13. The second motor 15 can drive the rotating rod 13 on one side to rotate. The outer walls of the multiple cams 14 are in close contact with the bottom plate 11. The rotation of the cam 14 can push the bottom plate 11 to move up and down.

[0022] Referring to Figure 3 , a connecting pipe 6 with a built-in valve is fixedly connected to the lower end of the mixing tank 2, which is convenient for transferring the mixed sewage inside the mixing tank 2 to the inside of the filtration tank 1, facilitating the filter plate 7 to filter the sewage. The lower end of the connecting pipe 6 is fixedly connected to the filtration tank 1. An outlet pipe 20 with a built-in valve is fixedly connected to the outer wall of the filtration tank 1, which is convenient for the filtration tank 1 to discharge the filtered sewage.

[0023] Referring to Figure 4 , on one side of the two rotating rods 13, a synchronous pulley 16 is fixedly connected. A synchronous belt 17 is sleeved on the outer wall of the synchronous pulley 16. Through the synchronous pulley 16 and the synchronous belt 17, the two rotating rods 13 can be driven to rotate.

[0024] Referring to Figure 2 , a water inlet hopper 19 is fixedly connected to the upper end of the mixing tank 2, which is convenient for pouring sewage into the inside of the mixing tank 2. A support frame 18 is fixedly connected to the outer wall of the mixing tank 2, which can support the mixing tank 2. The lower end of the support frame 18 is fixedly connected to the upper surface of the filtration tank 1.

[0025] The implementation principle of a sewage sedimentation and filtration device according to an embodiment of the present application is as follows: When in use, sewage is poured into the interior of the mixing tank 2 through the water inlet hopper 19. The first motor 4 drives the rotating shaft 3 to rotate, so that the rotating shaft 3 drives the stirring fan blades 5 to rotate, mixing the sewage and chemicals in the mixing tank 2. The mixed sewage is transferred to the interior of the filtration tank 1 through the valve on the connecting pipe 6, and the sewage falls on the surface of the filter plate 7 to filter the impurities in the sewage. At the same time, under the action of the second motor 15, the two rotating rods 13 can be driven to rotate through the two synchronous wheels 16 and the synchronous belt 17 on the outer wall, so that the cam 14 can push the bottom plate 11 and the slide rod 10 to move up and down, thereby driving the filter plate 7 to vibrate and preventing the impurities in the sewage from blocking the mesh holes on the surface of the filter plate 7.
