Technical Parameters

Applications
This equipment is designed for large-flow water intake scenarios, including:

• Drainage pumping stations

• River water intake structures

• Large-scale water conservancy pumping stations

It effectively intercepts large solid floating debris, ensuring unimpeded water flow and protecting downstream equipment.

Structure & Working Principle
The bar screen features a downward-backtracking design with a rotary chain mechanism. The grid surface consists of toothed rake plates and fixed bars. As wastewater flows through, debris larger than the bar spacing is trapped. The rake teeth penetrate the bar gaps and, driven by the rotary chain, lift debris upward to the discharge outlet. Upon descending, debris falls automatically by gravity into a conveyor or collection system for further handling.

Key Features

1. Efficient Drive System: Utilizes a cycloidal pinwheel or helical gear reduction motor, ensuring low noise, compact structure, and stable operation.

2. Enhanced Debris Handling: Specially designed斜尖型 (angled-tip) rake teeth welded to horizontal shafts for effective capture of large debris.

3. Robust Construction: Integral frame structure provides high rigidity, simplified installation, and minimal maintenance.

4. Flexible Control: Supports both local and remote operation for ease of use.

5. Overload Protection: Dual safety mechanisms—mechanical shear pins and overcurrent protection—ensure reliable and safe operation.

6. Anti-Short Circuit Design: A secondary grid is installed at the base to prevent water and debris bypass when the rake transitions from the back to the front side.
