Optimized Title:
NL Series Chain Flight Sludge Scraper System – High-Efficiency Scum and Residue Removal for Water Treatment Tanks
To Our Valued Customers,
We specialize in the manufacturing of a wide range of wastewater treatment equipment. Should you have any inquiries, please do not hesitate to contact us. Thank you.
Structure and Working Principle
The NL-type chain flight sludge and scum scraper system consists of a drive unit, drive sprocket assembly, guide rail and carriage, scraper flights, driven sprocket assembly, chain tensioning mechanism, sludge collection pipe, and other key components.
During operation, the chain drives the scraper flights in a continuous loop along the tank. The flights move settled sludge toward the sludge hopper for collection, while simultaneously removing floating scum or oil from the water surface.
