[0023] Working principle: The staff first pours sewage and sludge into the bottom plate 1 through the feed inlet 3. At this time, the sewage and sludge are filtered through the inclined filter plate 7. The sewage flows into the bottom of the filter chamber 2 through the filter plate 7 and is discharged through the outlet 4. The sludge rolls into the storage chamber 6 through the inclined filter plate 7. At this time, the vibration motor 20 is started. With the cooperation of the damper 21 and the telescopic spring 22, the filter chamber 2 is driven to vibrate, so that the filtering effect of the filter plate 7 is better. When the sludge on the filter plate 7 needs to be scraped, the servo motor 13 is started to drive the threaded rod 14 to rotate, thereby driving the threaded sleeve 15 to move, and then driving the telescopic rod 16 to move. Move, so under the limit of the limit rail 18 and the limit block 19, the telescopic rod 16 is used to drive the scraper 17 to move on the inclined filter plate 7, and then the sludge on the filter plate 7 is scraped off, so that the filtering effect of the filter plate 7 is better. When the filter plate 7 needs to be replaced, the fixing pin 11 is pulled out from the inside of the fixing hole 10, and then the filter plate 7 is pulled out from the inside of the filter chamber 2 with the cooperation of the fixing groove 8 and the movable rail 9, and then the filter plate 7 is installed in the inside of the filter chamber 2 with the cooperation of the fixing groove 8 and the movable rail 9, and the fixing pin 11 is inserted into the inside of the fixing hole 10 to limit the position of the filter plate 7, thereby completing the convenient installation of the filter plate 7.
