The Vertical Shaft Central Drive Sludge Scraper is designed for large circular clarifiers and thickeners, providing efficient sludge collection and discharge. A vertical rack structure supports the central drive unit, which transmits torque through a vertical shaft to the scraper arms. It ensures smooth operation, uniform torque distribution, and reliable performance under heavy loads and large diameters.
Working Principle
Wastewater flows into the clarifier via the central feed well, where solids settle by gravity. The central drive rotates scraper arms through a vertical shaft, collecting sludge toward the center hopper using blades and guide plates. Sludge is discharged by gravity or suction. The system includes automatic torque monitoring for overload protection and may include a surface scum skimmer.
Main Components
Vertical Rack & Drive Unit: Support structure and torque transmission
Vertical Shaft: Transfers power from gearbox to scraper arms
Scraper Arm & Blade: Directs sludge toward the central hopper
Feed Well & Baffle: Ensures uniform flow distribution
Sludge Hopper & Discharge System: Collects and removes sludge
Scum Removal System (optional): For surface scum cleaning
Control System: PLC automation with overload protection and alarms
Features
Uniform torque and smooth transmission with vertical rack design
Optional scum removal system for dual sludge-scum cleaning
Fully automated operation with minimal maintenance
Applications
