Advanced Working Principle: Continuous Self-Cleaning Action
This Mechanical Rake Bar Screen features a unique rake tooth assembly that forms a continuous rotating chain. Driven by an electric motor reducer, the chain moves counter-current to the wastewater flow, effectively intercepting and lifting solids. Upon reaching the upper part of the equipment, guided by sprockets and curved tracks, the rake teeth engage in a relative self-cleaning movement. The majority of captured debris falls off by gravity, while a dedicated cleaning brush ensures any remaining adhered material is thoroughly removed, guaranteeing an unobstructed screening surface.
Robust Construction & Customizable Design
Engineered for durability in harsh environments, the Automatic Mechanical Rake Bar Screen offers extensive customization. The screen gap, critical for separation efficiency, can be selected from 1mm to 50mm based on specific application needs. The main frame is available in carbon steel with anti-corrosion coating or stainless steel (SUS304/316) for superior corrosion resistance. Key components like rake teeth can be manufactured from stainless steel, nylon, or ABS engineering plastic to suit different operational conditions.
Key Advantages for Operational Excellence
High Automation & Intelligence: This Automatic Wastewater Bar Screen can operate continuously or at user-defined intervals. It can also be controlled automatically based on the liquid level difference across the screen, maximizing efficiency and reducing manual oversight.
Superior Separation Efficiency & Low Energy Use: The optimized rake design ensures highly effective solids capture. The system is designed for low power consumption, contributing to significant energy savings.
Exceptional Durability & Minimal Maintenance: The Mechanical Rake Wastewater Bar Screen is built with a simple yet robust structure and features an effective self-cleaning mechanism that prevents clogging. This results in very low daily maintenance requirements and a long service life.
Built-in Safety & Reliability: The equipment is equipped with an overload safety protection device. In case of an abnormality, it triggers an audio-visual alarm and shuts down automatically, preventing damage and ensuring operational safety.
Versatile Application Range
This highly adaptable bar screen is proven effective across a wide spectrum of applications. It is ideally suited for:
Inlet screening at municipal wastewater treatment plants (WWTPs).
Pre-treatment for industrial effluents from food and beverage, chemical, and manufacturing plants .
Pump station intake screening to protect downstream equipment from damage.
