[0019] The crushing assembly 3 includes a baffle 31. Three partition plates 32 are fixedly installed on the baffle 31. The partition plates 32 divide the two baffles 31 into two areas. A rotating shaft 33 is rotatably installed in the area closer to the second cross frame 24. Equally spaced blades 34 are fixedly installed on the outer surface of the rotating shaft 33. By rotating the rotating shaft 33, the blades 34 fixed to its outer surface are driven to rotate, so that the mud cake scraped off by the scraper 29 can be crushed, which greatly facilitates the recycling of the crushed mud cake.

[0020] At the bottom end of the area closer to the first cross frame 23, a collection box 14 is provided. The collection box 14 is fixedly installed at the bottom end of the baffle 31. A drain port 15 is fixedly clamped at the lower part of the collection box 14. A valve 151 is fixedly provided in the middle of the drain port 15. The collection box 14 can collect the sewage generated by the stripping and cleaning device 2, thus preventing environmental pollution.

[0021] On the upper surface of the base 1, two sets of symmetrically distributed third support columns 4 are fixedly installed on one side close to the rotating shaft 33. A transmission roller 42 is rotatably installed on the upper part of each set of third support columns 4. A conveyor belt 43 is movably sleeved outside the two transmission rollers 42. The conveyor belt 43 can transport the crushed mud cake to a suitable position, greatly improving the working efficiency.

[0022] On the side of the partition plate 32 close to the conveyor belt 43, a first fixing plate 36 is fixedly installed. A first motor 35 is fixedly installed on the upper surface of the first fixing plate 36. The driving end of the first motor 35 is connected to the end of the rotating shaft 33. The staff starts the first motor 35. Its driving end drives the rotating shaft 33 to rotate, and then the blades 34 fixed on the surface of the rotating shaft 33 rotate, so as to achieve the effect of crushing the mud cake.

[0023] On the upper part of the third support column 4, a second fixing plate 44 is fixedly installed. A second motor 41 is fixedly installed on the upper surface of the second fixing plate 44. The driving end of the second motor 41 is fixedly connected to the end of the transmission roller 42. The staff starts the second motor 41. Its driving end drives the transmission roller 42 to rotate, and then drives the conveyor belt 43 to rotate, so as to realize the transportation of the crushed mud cake.

[0024] Equally spaced water spray nozzles 271 are fixedly clamped on the outer surface of the water tank 27. By providing the water spray nozzles 271, the filter plate 13 after scraping off the mud cake can be fully cleaned. And the water spray nozzles 271 are opened on both sides of the water tank 27, thus improving the working efficiency of the device and avoiding environmental pollution.

[0025] Working principle: First, the staff will introduce the sewage into the filter press. After the filter press completes the filtering task, the staff will open the filter plate 13. At this time, most of the formed filter cakes can fall off by themselves, but there is still a small part of the filter cake adhering to the filter plate 13. Therefore, the staff will start the second linear electric rail 221, and its driving end will drive the second cross frame 24 to move to the corresponding position. Then, the second cylinder 28 will be started to push the scraper 29 downward to scrape off the residual or hard-to-fall-off filter cake on the filter plate 13. Next, the staff will start the first linear electric rail 22, and its driving end will drive the first cross frame 23 to move between the filter plates 13 after scraping off the filter cake. By connecting the water inlet hose 26 to the flusher, using the water spray nozzles 271 opened on both sides of the water tank 27, and with the cooperation of the first cylinder 25, the residual sludge on the surface of the filter plate 13 will be thoroughly washed off, ensuring the hygiene and cleanliness of the equipment, thus extending the service life of the equipment. At the same time, the water spray nozzles 271 on both sides greatly improve the work efficiency;

[0026] In addition, below the filter plate 13, there is also a baffle 31. There are three partition plates 32 distributed inside the baffle 31, dividing it into two areas. In one area, there is a rotating shaft 33 and a blade 34. The staff starts the first motor 35, and its driving end drives the rotating shaft 33 to rotate, thereby driving the blade 34 to rotate. When the filter cake on the surface of the filter plate 13 is scraped off by the scraper 29 and falls into this area, the blade 34 will break the filter cake. The broken filter cake then falls from the bottom of the baffle 31 onto the surface of the conveyor belt 43. When the second motor 41 is started, its driving end drives the driving roller 42 to rotate, thereby driving the conveyor belt 43 to rotate, so that the broken filter cake is transported to a suitable position, greatly facilitating the recycling of the broken filter cake and improving the work efficiency of the staff;

[0027] In the other area, when the water spray nozzles 271 wash the filter plate 13, the sewage will flow into the collection box 14 along the other area. There is also a drain port 15 at the bottom of the collection box 14 to drain the collected sewage for the next operation of the filter press. This not only realizes the maintenance and hygiene of the equipment, but also further collects the sewage and prevents environmental pollution.

[0028] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model is also intended to include these modifications and variations.
