Description
QDEVU sludge scraper has Full bridge, Half bridge and Truss type.
Full/half bridge sludge scraper is suitable for the collection and discharge of sludge in circular radial sedimentation tank. It is mainly composed of working bridge, center rotating support, scraper scraper, diversion cylinder, driving mechanism, slag retaining and slag discharging device, etc., which can meet the requirements of DN5-DN50 kinds of specifications and different water quantity of sedimentation tank.
The driving-type sludge scraper is suitable for collecting and discharging sludge from rectangular flat-flow sedimentation tank. It is mainly composed of working bridge, transmission device, scraper, sludge lifting pump and so on.
Working principle
Sludge scraper, sewage by central piers by diverting tube diffusion, mixture of massive particles by precipitation in the bottom sludge layer, the proportion of light floating in the liquid level, driving gear drives the work mud scraper bridge and set the sludge from pool week step by step toward the center of silt orifice discharge pool, sludge scraper along the guide tube will be floating scum on the liquid surface into the pool within weeks of discharge hopper, discharge outside the pool.
