1. Purpose
The ZBGX peripheral drive mud scraper and suction machine is suitable for large, medium and small diameter radial flow sedimentation tanks with central water inlet, peripheral water outlet and central mud discharge. It is mainly used for suction and discharge of mud in urban sewage treatment plants or sedimentation tanks.
2. Structure and working principle
The equipment adopts peripheral drive. Sewage flows in from the inlet pipe in the center of the pool. After being diffused by the steady flow tube, it flows out evenly and radially to the periphery. The suspended sludge is deposited at the bottom of the pool after sedimentation . The driving device drives the working bridge to rotate along the periphery, and drives the sludge suction pipe system and sludge collection scraper to rotate. The scraper scrapes the sludge and then uses the sludge suction pipe to pump the sludge into the sludge collection tank based on the hydrostatic pressure in the pool and discharges it into the central mud tank, and then discharges it out of the pool through the central sludge discharge pipe. The scum on the water surface is introduced into the sludge discharge hopper through the rotating slag spreading device and discharged out of the pool; while the supernatant liquid overflows into the outlet tank through the triangular outlet weir plate and is discharged.

4. Work characteristics
The working bridge can be of half-bridge type or full-bridge type, and its materials can be carbon steel, stainless steel, aluminum alloy, etc.;
The driving device adopts a shaft-mounted helical gear reducer and a direct transmission of the driving roller, which has a compact structure and high mechanical efficiency;
The mud suction pipe adopts the form of a bell mouth, which has good mud suction effect; there are two ways of mud suction: self-priming and siphon type (the former is conventionally used);
