Supply peripheral drive scrapers

The device uses the peripheral transmission, the center of the sewage into the water from the pool flows, the steady flow tube diffused, uniform flow radially to the periphery, in suspension after sedimentation sludge deposited on the bottom, the drive unit to drive the bridge work rotate along the perimeter and drive wiper arm and turn the scraper, scrape the sludge scraper set after the finale of suction pipe hydrostatic suction to rely on the pool set into the center of the mud bath mud tank, and then discharged through the center outside the pool, the water Written by rotating scum tie into slag hopper discharge device outside the pool; while the supernatant through the triangle formed weir plate spilled into the water tank discharge. Peripheral drive scrapers for central water, the surrounding water, mud center of large, medium and small pool diameter radial flow sedimentation tank, mainly for urban sewage treatment plant sludge secondary settling tanks suck.
