Vertical Shaft Center-Drive Sludge Scraper
Product Overview
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;
Ideal for large-diameter and deep circular tanks;
High structural rigidity and corrosion resistance;
Automatic torque protection ensures operational safety;
Optional scum removal system for dual sludge-scum cleaning;
Fully automated operation with minimal maintenance.
Applications
Primary and secondary clarifiers in municipal WWTPs;
Industrial wastewater sedimentation and thickening tanks;
Water treatment plant clarifiers and storage basins;
Large-scale sludge concentration and reuse systems.
Optional Configurations
Scum skimmer system – optional for surface cleaning;
Torque monitoring & overload protection – mechanical or electrical;
VFD control – for automatic speed regulation;
Corrosion protection – epoxy, galvanizing, or full stainless steel;
Bridge structure options – fixed, walking, or rotary;
