Product Introduction
Products Description
The center flow perforated plate screen delivers highly efficient secondary screening to remove fine suspended and granular debris. Its compact,
space-saving design ensures easy installation and user-friendly operation. Engineered for maximum durability, the system features zero underwater
transmission parts, significantly extending service life and preventing submerged mechanical failures.
Working Principle
The center flow perforated plate screen consists of a drive unit, main frame, stepped perforated panels, and a flushing system. Installed centrally in the channel, wastewater enters through a front opening and flows outward through the side-mounted panels, while baffles prevent any hydraulic bypass. As the motor drives the traction chain, the panels continuously lift intercepted debris from bottom to top. A pressurized flushing system then automatically
discharges the waste into a central trough for gravity removal. This unique "center-in, side-out" flow pattern ensures complete debris interception with strictly zero carry-over downstream. Featuring an advanced self-cleaning design, the system completely eliminates debris tangling, mechanical jamming, and bottom dead zones, achieving optimal pretreatment efficiency
