The above arrangement enhances the practicability of the device.

[0024] Specifically, the first guide groove 201 is connected to the first rotating shaft 202 by a slot, the inner diameter of the first guide groove 201 matches the outer diameter of the first rotating shaft 202 , and the first rotating shaft 202 can rotate in the first guide groove 201 .

[0025] Specifically, the first guide trough 201 is slidably connected to the first screen 204 , and the length of the first screen 204 is slightly longer than the first guide trough 201 , so as to facilitate the separation of wastewater and aggregate.
