The connecting groove 311 slides upward, driving the blocking plate 310 to move upward, and the second motor 302 is started. When the second motor 302 is turned on, the worm 304 drives the worm wheel 307 to rotate, so that the ball nut seat 306 will rotate. When the ball nut seat 306 rotates, the first screw 308 will be driven to move horizontally, and the first screw 308 will drive the sewage discharge plate 309 to discharge sewage, and discharge the sludge in the shell 1.

When passing through the filter screen 210, the water in the sewage will continue to flow downward into the water storage tank 4, while the sludge will be filtered out by the filter screen 210. During filtration, the first motor 205 is started, and the first motor 205 causes the rotating rod 206 to drive the eccentric block 208 to rotate. When the eccentric block 208 rotates, the vibration block 203 will vibrate at one end of the connecting block 201 through the spring 202, so that the vibration block 203 will drive the filter screen 210 to vibrate through the filter plate 209, preventing the sludge from clogging the filter screen 210, and achieving a better filtering effect. Secondly, when the spring 202 is extended and retracted, The limit rod 204 can limit the movement of the spring 202, thereby increasing the service life of the spring 202. When discharging sludge, loosen the nut 313 and move the second screw 312. The second screw 312 slides upward in the connecting groove 311, driving the blocking plate 310 to move upward, and start the second motor 302. When the second motor 302 is turned on, the worm 304 drives the worm wheel 307 to rotate, so that the ball nut seat 306 will rotate. When the ball nut seat 306 rotates, the first screw 308 will be driven to move horizontally, and the first screw 308 will drive the sewage discharge plate 309 to discharge sewage.
