The inside of the connecting cylinder 201 is provided with an auger 202. The end of the connecting cylinder 201 away from the sedimentation tank 104 is communicated with a discharging pipe 203.

[0031] The secondary dynamic separation unit 300 comprises a separation sieve plate 301 and a separation tank 302. The separation sieve plate 301 is located inside the separation tank 302. The separation tank 302 is in communication with the bottom end of the discharging pipe 203. The inside of the separation tank 302 is provided with a water collecting barrel 303. The water collecting barrel 303 is sleeved on the separation sieve plate 301. The water collecting barrel 303 is rotatably connected with the separation sieve plate 301. The bottom of the separation sieve plate 301 is fixedly connected with a rotating shaft 304. The bottom end of the rotating shaft 304 penetrates through the water collecting barrel 303. The inner wall of the separation tank 302 is fixedly installed with a driving motor 305. The output end of the driving motor 305 is connected with the rotating shaft 304.

This design can improve the screening efficiency while avoiding the accumulation of solid impurities on the sieve plate.

[0033] In another embodiment, one side of the water collecting barrel 303 is communicated with a drain pipe 307, and the drain pipe 307 is communicated with the water outlet pipe 103. In this way, the clean water after screening can be discharged, realizing the recycling of water resources.
