[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. In the present utility model, by providing an auxiliary device, when sludge needs to be filtered, first pour the sludge into the funnel. Then, the sludge inside the funnel passes through the filter screen, and the water inside it will enter the filter box. The impurities in the sludge stay on the surface of the filter screen, thus completing the impurity removal and filtration operation of the sludge. After the filter screen is blocked, first start the electric telescopic rod. The electric telescopic rod starts to drive the support frame to move inside the chute. The movement of the support frame inside the chute drives the funnel to move. The movement of the funnel makes it move away from the upper part of the filter box. When the funnel moves away from the upper part of the filter box, turn off the electric telescopic rod. Then slide the moving plate so that the moving plate moves inside the strip-shaped groove. The movement of the moving plate inside the strip-shaped groove will squeeze the spring, causing the spring to be compressed under force and also driving the insertion rod to move. The movement of the insertion rod makes it move out of the jack. The separation of the insertion rod and the jack causes the filter screen and the support frame to lose the limit. At this time, the filter screen can be rotated to a vertical state, so that the impurities on the surface of the filter screen slide off the surface of the filter screen and into the bearing box, completing the cleaning operation of the impurities on the surface of the filter screen. When the impurities on the surface of the filter screen are cleaned up, rotate the filter screen back to the horizontal state, and then continue to complete the impurity removal and filtration of the sludge. Through the cooperation of the above structures, it is possible to clean the impurities on the surface of the filter screen without disassembling the filter screen, further improving the impurity removal efficiency, and ultimately also improving the filtration efficiency of the sludge.

[0013] 2. In the utility model, by setting an adjustment device, when it is necessary to adjust the height of the carrying box, first start the motor, the motor starts to drive the threaded rod to rotate, the threaded rod rotates to drive the movable plate to move inside the groove, the movable plate moves inside the groove to drive the connecting rod to move, the connecting rod moves to drive the carrying box to move, the carrying box moves to drive the displacement plate to move inside the vertical groove, when the carrying box moves to a suitable height, turn off the motor, through the cooperation of the above structure, the distance between the carrying box and the filter can be adjusted, so that when removing impurities on the surface of the filter, the carrying box can better receive the impurities removed from the surface of the filter to avoid scattering around.

A plug rod 208 is fixedly installed on the surface of the moving plate 207. A jack 209 is provided on the inner wall surface of one side of the U-shaped frame 205. A spring 210 is fixedly installed between the moving plate 207 and the inner wall surface of one side of the strip-shaped groove 206. The setting of the spring 210 restricts the position of the moving plate 207 inside the strip-shaped groove 206.

[0030] In this embodiment, the side of the filter box 1 is provided with an adjustment device 3, which includes a vertical slot 31, which is opened on the side of the filter box 1, and a displacement plate 32 is slidably connected inside the vertical slot 31, and a bearing box 33 is fixedly installed on the surface of one end of the displacement plate 32 away from the vertical slot 31. When the height of the bearing box 33 needs to be adjusted, the motor 36 is first started, and the motor 36 starts to drive the threaded rod 35 to rotate, and the threaded rod 35 rotates to drive the movable plate 38 to move inside the groove 37, and the movable plate 38 moves inside the groove 37 to drive the connecting rod 39 to move, and the connecting rod 39 moves to drive the bearing box 33 to move, and the bearing box 33 moves to drive the displacement plate 32 to move inside the vertical slot 31. When the bearing box 33 moves to a suitable height, the motor 36 can be turned off.

[0033] Specifically, a groove 37 is formed on the inner wall surface of the U-shaped plate 34 , a movable plate 38 is threadedly connected to the surface of the threaded rod 35 , and a connecting rod 39 is fixedly installed between the movable plate 38 and the carrying box 33 .

[0034] In this embodiment, the connection rod 39 is provided to drive the carrying box 33 to move.

[0035] Working principle: by setting the auxiliary device 2, when it is necessary to filter the sludge, first pour the sludge into the interior of the funnel 6, and then the sludge inside the funnel 6 is filtered through the filter screen 203, and the moisture inside it will enter the interior of the filter box 1, and the impurities in the sludge will stay on the surface of the filter screen 203, thereby completing the impurity removal and filtering operation of the sludge. When the filter screen 203 is blocked, first start the electric telescopic rod 8, and the electric telescopic rod 8 starts to drive the support frame 5 to move inside the slide 4. The movement of the support frame 5 inside the slide 4 drives the funnel 6 to move, and the funnel 6 moves to move itself away from the top of the filter box 1. When the funnel 6 is away from the top of the filter box 1, close the electric telescopic rod 8, and then slide the moving plate 207 to move the moving plate 207 inside the strip groove 206. The movement of the moving plate 207 inside the strip groove 206 will squeeze the spring 210 , so that the spring 210 is compressed and the plug rod 208 is driven to move, and the plug rod 208 moves to move itself out of the inside of the hole 209, and the plug rod 208 and the hole 209 are separated, so that the filter screen 203 and the support frame 5 lose the limit. At this time, the filter screen 203 can be rotated to a vertical state, so that the impurities on the surface of the filter screen 203 slide from the surface of the filter screen 203 into the interior of the carrier box 33, and the impurities on the surface of the filter screen 203 are cleaned. When the impurities on the surface of the filter screen 203 are cleaned, the filter screen 203 is rotated to a horizontal state again, and then the impurity removal and filtration of the sludge are continued. Through the cooperation of the above structure, the impurities on the surface of the filter screen 203 can be cleaned without disassembling the filter screen 203, which further improves the impurity removal efficiency and ultimately improves the sludge filtering efficiency. When the height of the carrying box 33 needs to be adjusted, the motor 36 is first started. The motor 36 starts and drives the threaded rod 35 to rotate. The threaded rod 35 rotates and drives the movable plate 38 to move inside the groove 37. The movable plate 38 moves inside the groove 37 and drives the connecting rod 39 to move. The connecting rod 39 moves and drives the carrying box 33 to move. The movement of the carrying box 33 drives the displacement plate 32 to move inside the vertical groove 31. When the carrying box 33 moves to a suitable height, the motor 36 is turned off. Through the cooperation of the above-mentioned structure, the distance between the carrying box 33 and the filter 203 can be adjusted, so that when removing impurities on the surface of the filter 203, the carrying box 33 can better receive the impurities removed from the surface of the filter 203 to avoid scattering around.
