Application scenarios：
The non metallic chain scraper is mainly used in horizontal flow grit chambers or sedimentation tanks of wastewater treatment plants. It uses non metallic chains to drive the scrapers, continuously scraping sand, sludge, or suspended solids deposited at the bottom of the tank to the grit collection pit or sludge discharge port, achieving efficient, low noise, and low maintenance sand and sludge scraping operations.
Structure&Principle：
Structure: It is mainly composed of non metallic chains (engineering plastic), scrapers, a drive unit, a tensioning device, a track system, guide wheels, and a sand/sludge collection trough.
Principle: The drive unit drives the non metallic chains to circulate along the track system at the bottom of the tank. As the chains move, the scrapers continuously push the sand or sludge deposited on the tank bottom toward the sand collection pit or sludge discharge port. The collected material is then discharged by gravity or with the assistance of auxiliary equipment, achieving continuous, stable, and low noise sand and sludge scraping.
Main Features：
1. Rational layout and high space utilization rate.
2. A large number of scraper plates provide strong sludge scraping capacity; the slow moving speed of the scrapers minimizes disturbance to the wastewater, 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. Energy saving: plastic components are lightweight and easy to move, resulting in low power consumption.
5. Equipped with sprocket movement monitoring, scraper monitoring, and overload protection devices, with signals fed back to the control room.
