Traveling Bridge Sludge Scraper 0.3m/Min – 2.0 M/Min Industrial Scraper 60m Tank

Traveling Bridge Sludge Scraper
Product Overview

The Traveling Bridge Sludge Scraper is mainly used for rectangular or horizontal-flow sedimentation tanks.
The traveling bridge moves back and forth, driving the scraper blades to push settled sludge along the bottom to the sludge hopper for discharge.
It features stable operation, lightweight design, and easy maintenance, making it suitable for primary and secondary clarifiers in municipal and industrial wastewater plants.

Working Principle

The scraper operates on dual traveling rails driven by a motor and gearbox, moving the bridge back and forth along the tank.
During forward motion, the scraper pushes sludge to the sludge trough; on the return stroke, the scraper lifts to reduce resistance.
Collected sludge is discharged through the outlet pipe, and optional skimming devices remove floating scum, enabling continuous automatic operation.

Main Components

• Traveling Bridge: Carries drive and scraper mechanisms; lightweight and rigid design.

• Drive Unit: Motor, gearbox, and drive wheels for motion control.

• Scraper Blade: Rubber or stainless steel, closely fits the tank bottom for sludge pushing.

• Traveling Rail: Installed on both sides of the tank top for smooth bridge movement.

• Sludge Hopper & Pipe: Collects and discharges sludge.

• Control System: Supports PLC automation, torque protection, and fault alarms.

Features

• Stable operation with low noise and efficient sludge removal;

• Compact and lightweight design with low power consumption;

• Capable of both bottom sludge scraping and surface scum skimming;

• Supports automatic start/stop and torque protection;

• Easy maintenance and ideal for large or medium wastewater treatment plants.

Applications

• Municipal Wastewater Treatment Plants – For sludge collection and discharge in primary and secondary clarifiers.
