304 Stainless Steel Center Drive Scraper for Circular Wastewater Treatment
This centrally-driven sludge scraper is specifically designed for radial flow (circular) sedimentation tanks with diameters up to 18 meters in water treatment plants and municipal sewage facilities. The system efficiently collects and removes settled sludge through a robust减速 drive mechanism and suspended scraper assembly. Sludge is guided toward a central collection hopper and discharged via hydrostatic pressure or pumping systems. Featuring a central inlet and sludge discharge with peripheral overflow weirs, the tank ensures uniform flow distribution and optimal settling conditions. The system includes an integrated skimmer for surface scum removal and is equipped with overload protection for reliable, automated operation.
Key Features:
Constructed with corrosion-resistant 304 stainless steel for extended service life
Central drive design with precision reduction gearing for consistent torque output
Central feed and sludge discharge with peripheral water collection for balanced hydraulic flow
Automated skimming system for efficient surface scum removal
Integrated overload protection prevents damage during operation
Suitable for tanks up to 18 meters in diameter
Typical Applications:
Municipal wastewater treatment plants
Drinking water treatment sedimentation basins
Industrial wastewater circular clarifiers
Water reuse and recycling facilities
Working Principle:
The scraper system rotates continuously, moving settled solids toward the central hopper while surface skimmers remove floating materials. The balanced hydraulic design maintains ideal settling conditions while the robust drive system ensures reliable operation with minimal maintenance requirements.
