Stainless Steel Traveling Bridge Sludge Scraper and Suction Machine for Wastewater Treatment
This traveling bridge-type sludge removal system is designed for horizontal sedimentation tanks in municipal and industrial wastewater treatment plants. It efficiently collects and extracts settled sludge by traversing the tank length, simultaneously scraping and pumping out the waste for continuous tank cleaning and optimal sedimentation performance.
Product Features
Robust & Lightweight Truss Structure: The bridge utilizes a high-strength truss design that is lighter than conventional structures, reducing overall weight while extending service life. Travel wheels are made of hardened steel for enhanced durability.
Low Operation & Maintenance Costs: Requires minimal maintenance, features low power consumption, and is equipped with optimally selected pumps for stable, reliable, and cost-efficient performance.
Precise Travel Control: An advanced drive mechanism ensures synchronized movement on both sides, eliminating tracking errors and preventing deviation during operation.
Main Components
The system primarily consists of:
Traveling bridge frame
Submerged suction pumps
Sludge suction pipes and discharge headers
Bilateral drive unit
Electrical control cabinet
Running tracks and travel switches
Cable management system (cable reel or sliding collector)
Working Principle
The equipment is supported by a dual-beam structure that spans the sedimentation tank, with bilateral drives ensuring balanced movement. Rails installed on both sides of the tank guide the machine. As it travels from one end of the tank to the other, the submerged suction pumps extract sludge while in motion. Upon reaching the end of the tank, the machine automatically reverses direction after contacting the limit switch, returning to the starting position while continuing suction operations, completing a full working cycle.
