| High Light | Modular submerged monorail sludge scraper ，Flexible sludge scraper for wastewater treatment ，Robust sludge removal equipment with high-concentration discharge | ||
The DG Series Monorail Submerged Scraper is engineered for efficient sludge removal in rectangular clarifiers, tube settlers, and DAF tanks within large water and wastewater treatment plants. This system features a simple structure, reliable transmission, comprehensive electrical protection, and easy installation, making it ideal for automated operations.
Utilizing a continuous chain reciprocating drive mechanism, the system tows a scraper trolley back and forth to effectively move bottom sludge from the outlet zone to the inlet collection hopper. This ensures high-concentration sludge discharge and superior overall removal efficiency.
The Monorail Submerged Sludge Scraper system comprises four main components: Drive Unit, Scraper Carriage Assembly, Rail System, and Electrical Control Unit.
Features a motor, double-stage cycloidal reducer, and overload-shear sprocket assembly that drives the continuous chain. Reciprocating motion is achieved by motor reversal, with all components fully enclosed. Chain transmission provides excellent flexibility, high traction, and precise ratios without excessive tension requirements.
Includes frame, wheels, scraper blades, and flipping device. Connection lugs link the carriage to the chain, forming a closed loop. Towed by the drive unit, the carriage travels along rails for forward (scraping), backward (reset), and flipping actions. In long clarifiers, bumper-rod linkages synchronize multiple carriages.
Consists of head, tail, and intermediate rails (for extended tanks) installed along the tank's centerline. Provides a flat, reliable track with chain-reversing devices equipped at both ends.
Supports Local and Remote operation modes, controlling scraping and return cycles with accurate reversing upon signal reception. Each cycle completes with adjustable standby delay (1-999 minutes). Signal bumpers at both ends trigger the linkage system, activating limit and proximity switches to convert mechanical limits into electrical reversing signals for highly reliable operation.
