Center Drive Sludge Scraper

The center drive sludge scraper is supporting equipment for the radial sedimentation clarifier. water inflows into the clarifier from the middle part, and the sludge sinks to the bottom of the tank. Clean water flows out, and the bottom sludge is scarpered to the pit and finally discharged. The central drive scraper also has the function of blocking and scraping the scum on the surface of the tank, which is optional.   How Sludge scraper works ？   The working principle of the Sludge scraper: When the Sludge scraper is working, the working bridge is driven by the driving mechanism installed on the periphery and rotates around the central support installed on the central pier of the pool. The Sludge scraping device installed on the working bridge rotates. During the process, the sludge settled at the bottom of the tank is scraped to the sludge collecting bucket in the center of the tank.   When the scraper encounters excessive sludge hardening or obstacles, it generates excessive resis…
