[0030] The cleaning component 3 includes a fixed slot 305 which is opened at the upper end of one side inside the filter box 5. One side of the filter box 5 is fixedly connected with a micro servo motor 301. The output end of the micro servo motor 301 extends into the fixed slot 305 and is fixedly connected with a threaded rod 303 through a coupling. The surface of the threaded rod 303 is threadedly connected with a threaded block 304. The upper end of one side of the threaded block 304 is fixedly connected with a scraper 302. By starting the micro servo motor 301 to drive the threaded rod 303 to rotate, the threaded block 304 slides to drive the scraper 302 to slide, so as to scrape and clean one side of the filter plate 10, sweep away the impurities adhered to its surface and let them fall, and discharge them through the electric sewage discharge square pipe 6. Then, automatic cleaning and discharging can be realized, avoiding the blockage of the filter plate 10 caused by the untimely disassembly and assembly of traditional staff.

Then, the mounting block 102 can be driven to slide the sealing plate 2, and the filter plate 10 can be taken out from the inside of the filter box 5 for thorough cleaning and anti-blocking. When installing, the filter plate 10 is inserted into the inside of the filter box 5 from the reserved groove 12, and the sealing plate 2 is made to be inserted into the inside of the reserved groove 12. At this time, by utilizing the sealing gasket 11, the sealing performance of the sealing plate 2 inserted into the inside of the reserved groove 12 is improved. Then, the rotating plate 101 is rotated and clamped into the inside of the mounting block 102. At this time, by utilizing the deformation of the rubber pad 103, the clamping firmness and stability between the rotating plate 101 and the mounting block 102 are improved, thereby ensuring the firmness and stability of the installation of the filter plate 10 and realizing the quick disassembly and assembly action between the sealing plate 2 and the filter plate 10.
