Application scenarios：
The non-metallic chain scraper is used in horizontal flow sedimentation tanks to scrape sludge from the bottom and skim scum from the surface, achieving solid-liquid separation.
Structure&Principle：
The equipment is mainly composed of a drive unit, driving sprocket, driven sprocket, non-metallic chains, scrapers, scum scrapers, guide rails, tensioning device, and an electrical control system.
Working Principle: The drive unit rotates the driving sprocket, causing the non-metallic chains on both sides to move slowly along the guide rails at the bottom of the tank. The scrapers attached to the chains move accordingly, continuously scraping the settled sludge toward the sludge hopper for discharge through the sludge pipe. At the same time, the scum scrapers on the chains operate on the water surface, pushing the scum into the scum trough for removal, thereby achieving solid-liquid separation.
Main Features：
1. Rectangular design with a more rational layout and higher space utilization.
2. Equipped with multiple scraper plates for strong sludge scraping capacity; the slow movement speed of the scrapers minimizes disturbance to the sewage, facilitating sedimentation of sludge and sand.
3. Main components are made of corrosion resistant materials, featuring light weight, easy installation, and a long service life.
4. No heavy structural or supporting parts, resulting in low system energy consumption and maintenance costs.
5. Can function as a skimmer simultaneously without requiring additional mechanisms.
6. Energy efficient, with lightweight and easily movable plastic components that minimize power consumption.
7. Equipped with sprocket movement monitoring, scraper monitoring, and overload protection devices, with signals fed back to the control room.
