Product Description
Center Drive Sludge Scraper 0.2 – 2.0 M/Min Rotating Sludge Scraper
Product Overview
The Central Drive Sludge Scraper is designed for circular sedimentation and thickening tanks to collect and discharge settled sludge from the tank bottom. Driven by a central gearbox, the scraper arms rotate slowly, pushing sludge toward the central hopper for discharge, while optional skimmers remove surface scum. It features simple structure, reliable operation, and easy maintenance, making it ideal for municipal and industrial wastewater treatment plants.
Working Principle
Wastewater enters through the central feed pipe and distributes evenly within the circular tank. Under gravity, solids settle at the bottom. The central drive mechanism rotates scraper arms slowly, directing sludge toward the center hopper for discharge by gravity or suction. Surface scum is collected by the scum skimmer and discharged via the scum trough. The system supports automatic operation and overload protection.
Main Components
  • Central Drive Unit: Gear reducer and shaft assembly driving scraper rotation.
  • Scraper Arm & Blades: Radially arranged arms directing sludge to center.
  • Central Bearing Support: Ensures smooth rotation and torque stability.
  • Sludge Hopper & Discharge Pipe: Collects and removes sludge.
  • Scum Skimmer (Optional): Removes floating scum from surface.
  • Bridge or Platform: Supports drive unit and provides access.
  • Control System: PLC control with overload protection.
