The side wall array of the roller 12 is fixedly provided with a dredging protrusion 13. The dredging protrusion 13 is plugged into and matched with the sieve holes of the centrifugal screen drum 8. By setting the dredging unit, the centrifugal screen drum 8 installed on the supporting shaft 7 is driven by the motor 9 to rotate, and the roller 12 on the rotating shaft rotates therewith. The dredging protrusion 13 on the roller 12 can flush out the blockage embedded in the sieve hole during the process of inserting into the sieve hole of the centrifugal screen drum 8, so as to realize the dredging of the sieve hole of the centrifugal screen drum 8, avoid the blockage of the centrifugal screen drum 8, and ensure that the device can continuously and efficiently separate the solid and liquid of the wastewater.

[0019] There are multiple dredging units, which are arranged in a circular array around the centrifugal screen drum 8.
