4.0Kw Mechanical Bar Screen for Water Conservancy Pump Stations

SL Series Mechanical Bar Screen for Water Conservancy Pump Stations | China Water Treatment Solution

Company Profile
We specialize in the development and manufacturing of advanced treatment equipment for the petrochemical industry, municipal water services, urban and industrial wastewater treatment, domestic sewage purification, pure water systems, reverse osmosis technology, water supply purification, and waste gas pollution control.

Key Parameters and Installation Dimensions

Applications

Designed for large-flow water intakes, this bar screen is widely used in:

• Drainage pumping stations

• River water intake facilities

• Large-scale water conservancy pump stations

It effectively intercepts large solid floating debris to ensure unimpeded water flow and protect downstream equipment.

Structure and Working Principle

The SL series adopts a downstream-back type rotary chain mechanism. The screen surface consists of toothed rake plates and fixed bars.

Operation Process:

1. Wastewater flows through the bar screen, where debris larger than the bar spacing is captured.

2. The toothed rake plates penetrate the bar gaps and are driven by a traction chain in a continuous rotary motion.

3. Debris is lifted upward from the bottom and discharged at the top outlet.

4. As the rake plates move downward, debris falls by gravity into a conveyor or collection hopper for further processing.

5. A secondary screen is installed at the bottom to prevent hydraulic short-circuiting and ensure complete debris removal.

Key Features

1. Efficient Drive System: Cycloidal pinwheel or helical gear reduction motor ensures quiet, compact, and stable operation.

2. High-Capacity Rake Design: Oblique-tip rake teeth integrated with horizontal shafts enable effective capture of large debris.

3. Robust Structure: One-piece frame offers high rigidity, easy installation, and minimal maintenance.

4. Flexible Control: Supports both local and remote operation for seamless integration into automated systems.

5. Dual Overload Protection: Equipped with mechanical shear pins and electrical overcurrent protection for enhanced safety.

6. Anti-Short Circuit Design: Secondary screen prevents debris bypass, improving separation efficiency.

Ideal For:
High-flow water conservancy projects, municipal drainage systems, and large pump stations requiring reliable coarse screening.
