Why Choose Longdai?
Decades of Expertise: Over 10 years of specialized experience in wastewater and sludge treatment technologies.
German-Engineered Excellence: Core technologies integrated from German partners, ensuring superior performance compared to conventional Chinese manufacturers.
Premium Components: Only high-quality parts from certified global suppliers are used.
End-to-End Capability: In-house R&D center and full-cycle manufacturing system for strict quality control.
Applications
This system is ideal for residential and urban sewage pretreatment.
Its modular design adapts to varying channel widths and flow rates.
Key components include a base frame, patented plough-shaped tines,
rake plates, elevator chains, and motor-reducer units. The rake
plates, mounted on chains, perform continuous clockwise movement to
capture and elevate debris from the bottom to the discharge point.
Working Principle
The bar screen operates via a downward-backtracking rotary chain mechanism. As sewage flows through, the fixed bars intercept large debris.
The toothed rake plates penetrate the bar gaps and transport
trapped solids upward via chain rotation. At the top, debris is
discharged by gravity or guided into a conveyor system. A secondary
grid prevents hydraulic short-circuiting during rake reversal.
Key Features
Quiet & Robust Drive: Cycloidal pinwheel/helical gear reduction motor ensures low-noise, stable operation.
High-Efficiency Raking: Oblique-tip rake teeth welded to horizontal shafts for optimal debris capture.
Rigid Frame Construction: One-piece frame design simplifies installation and reduces maintenance.
Flexible Control: Local and remote operation support for seamless integration.
Dual Overload Protection: Mechanical shear pins + overcurrent protection for operational safety.
Anti-Short Circuit Design: Secondary grid eliminates debris bypass during rake cycling.
