The center rotating scraper is widely used for sedimentation tank sludge discharge in water supply engineering, and the overall load of the machine is applied to the center of the working bridge. The sewage flows into the surrounding overflow tank after being distributed by the central stabilizing cylinder. As the flow rate decreases, the suspended solids in the sewage are separated and settled at the bottom of the tank. The settled sludge is scraped by a scraper into the central collection tank and discharged from the sludge pipe by static water pressure.
The size of the device design should be determined according to user requirements and the platform.
