[0023] In the embodiment, the motor 10 drives the lead screw 11, the sliding plate 12 and other components to move up and down, and the shower head 18 sprays water in all directions in cooperation with the evenly distributed shower heads 18 on the water distribution shell 17, so that the filter cloth 4 and the filter plate 3 are fully covered and cleaned. Compared with the manual cleaning method, the dynamic and static combined water spraying method greatly improves the cleaning efficiency and can completely flush the residual sludge in a short time, saving a lot of time for the equipment to quickly enter the next round of work.

[0024] Embodiment 2: as Figure 5 shown, the bottom of the box 1 is provided with a sludge discharge port 23, and the side of the box 1 close to the hydraulic cylinder 5 is symmetrically provided with a mounting plate 24, the bottom of the mounting plate 24 is fixedly provided with an electric telescopic rod 25, the output end of the electric telescopic rod 25 is fixedly provided with a long plate 26, one end of the long plate 26 away from the electric telescopic rod 25 is fixedly provided with a sealing element 27, and the sealing element 27 is slidably connected with the sludge discharge port 23.

[0025] In this embodiment, the long plate 26 is pushed downward by the electric telescopic rod 25, and the sealing element 27 slides downward in the sludge discharge outlet 23 during the downward movement of the long plate 26. After sliding for a certain distance, the sealing element 27 is separated from the sludge discharge outlet 23. After separation, the filter cake accumulated on the filter cloth 4 after pressure filtration can be discharged from the sludge discharge outlet 23, thereby improving the discharge efficiency of the filter cake and facilitating the operation of the operator.

[0026] The working principle of the present embodiment is as follows: in use, first, the sludge to be treated is poured into the box body 1, and the poured sludge is located between the filter cloth 4 and the pressing plate 6. Then, the hydraulic cylinder 5 is started to push the pressing plate 6 to move stably in the box body 1 towards the filter cloth 4. With the advancement of the pressing plate 6, the sludge is subjected to continuously increasing pressure, and the water in the sludge is filtered through the filter cloth 4 and discharged from the box body 1 along the drain pipe 7, realizing preliminary solid-liquid separation. The solid part is gradually accumulated on the surface of the filter cloth 4 to form a filter cake. When the sludge after pressure filtration needs to be discharged, the electric telescopic rod 25 is started to push the long plate 26 to move downward, and the sealing element 27 slides downward in the sludge discharge outlet 23 during the downward movement of the long plate 26. After sliding for a certain distance, the sealing element 27 is separated from the sludge discharge outlet 23. After separation, the filter cake accumulated on the filter cloth 4 after pressure filtration can be discharged from the sludge discharge outlet 23. When the filter cloth 4 and the filter plate 3 need to be cleaned, first, the external clean water source is connected to the water tank 14 through the water inlet pipe 15 to provide sufficient water for cleaning. After connection, the water pump 20 is started. The input end of the water pump 20 draws water from the water tank 14 through the pipeline one 21. After being pressurized by the water pump 20, the water is transported to the water distribution shell 17 through the pipeline two 22 of the output end. Since the nozzles 18 are uniformly fixed on the outer wall of the water distribution shell 17, the water entering the water distribution shell 17 is scattered and uniformly sprayed through the nozzles 18. At the same time, the motor 10 at the top of the vertical rod 8 is started. When the motor 10 works, the lead screw 11 rotates and drives the sliding plate 12 to move up and down along the sliding groove 9. The connecting plate 13 at one end of the sliding plate 12 moves synchronously, thereby driving the water tank 14, the connecting column 16, the water distribution shell 17 and the nozzles 18 installed on the connecting plate 13 to move up and down as a whole, ensuring that the water flow sprayed by the nozzles 18 can fully cover each area of the filter plate 3 and the filter cloth 4, and the residual sludge is washed in all directions, thereby achieving the purpose of efficient and automatic cleaning.

[0027] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
