ZCCG vertical center drive scraper

The ZCCG vertical center drive scraper is suitable for medium to large diameter radial flow sedimentation tanks with central inlet, peripheral outlet, and central discharge. It is mainly used for discharging sludge from secondary sedimentation tanks in urban sewage treatment plants.

Structure and working principle

The equipment adopts a central transmission and vertical frame type. After the sewage flows into the guide tube through the inlet pipe and diffuses, it flows out uniformly in a radial manner to the periphery. The suspended sludge settles at the bottom of the pool after sedimentation. The driving device drives the central vertical frame to rotate, and drives the scraper wall and scraper plate to rotate. The sludge is scraped from the periphery of the pool to the central collection tank, and then discharged outside the pool through the sludge discharge pipe by the static water pressure inside the pool. The floating slag on the water surface is skimmed to the edge of the pool by the skimming device, and then hung into the slag hopper by the scraper rake and discharged outside the pool; The supernatant overflows into the water outlet tank through a triangular weir plate and is discharged.
