The side of the filter box 5 near the horizontal center of the water collection tank 2 is inclined from bottom to top towards the horizontal center of the water collection tank 2. The open structure facilitates the dumping of sludge. The water outlet at the lower end of the front side of the water collection tank 2 is equipped with a water outlet pipe 10. The water flows through the filter hole at the bottom of the filter box 5 and falls into the interior of the water collection tank 2 and then is discharged through the water outlet pipe 10. The upper end of the water collection tank 2 is equipped with a diversion pipe 11. The branch pipes at the front end of the diversion pipe 11 are located above the filter box 5, connecting the external sewage pipe to the rear end of the diversion pipe 11. The middle of each branch pipe is connected in series with an electric valve 12. The input end of the electric valve 12 is electrically connected to the output end of the controller 7. When one of the electric valves 12 is opened, the sewage will flow out from the branch pipe on the front side of the diversion pipe 11 and fall onto the top of the filter box 5.

During operation, the controller 7 is adjusted, and the vibration motor 6 drives the collection tank 2 to vibrate under the support of the spring 3. The controller 7 controls one of the electric valves 12 to open, allowing sewage to flow out from the branch pipe on one side of the front end of the diversion pipe 11, falling onto the filter box 5. The water then flows through the filter holes at the bottom of the filter box 5 and falls into the collection tank 2, then is discharged through the outlet pipe 10. Sludge will remain above the filter box 5. Simultaneously, the collection tank 2 drives the filter box 5 to vibrate via the support shaft 4, thereby accelerating the sludge-water separation speed. After a certain period of operation, the two electric valves 12 switch operation, allowing sewage to flow to the... Another filter box 5 discharges wastewater for filtration. The filter box 5 with the water inlet stopped vibrates and dewaters. After dewatering for a period of time, the servo motor 96 starts. The output shaft of the servo motor 96 drives the lead screw 94 to rotate. The lead screw 94 drives the rack 92 to slide along the slide block 91 towards the dewatered filter box 5 through the nut 95. Then the rack 92 contacts and meshes with the gear 93 on one side. The rack 92 drives the support shaft 4 and the filter box 5 to rotate upward through the gear 93. The filter box 5 is lifted up to pour out the sludge inside. The sludge falls into the inside of the chute shell 8 and is discharged from the front of the chute shell 8. At the same time, the filter box 5 and the chute shell 8 have a good separation effect on the sludge under vibration. During the operation, the two filter boxes 5 can work in turn.
