1mm – 50mm Mechanical Bar Screen SS304 7.5KW Sewage Bar Screen
High-Performance Mechanical Bar Screen For Sewage And Industrial Wastewater Pretreatment
The mechanical bar screen is a key piece of equipment used in the pretreatment stage of wastewater treatment systems. It is designed to remove large suspended solids, floating debris, and solid waste from wastewater, preventing blockage or damage to downstream equipment such as pumps and aerators.
With its simple structure, stable operation, high level of automation, and easy maintenance, this machine enables efficient and continuous solid-liquid separation and supports unattended operation of wastewater facilities.
Working Principle
The mechanical bar screen consists of a bar rack installed in the channel and a rotating chain rake system. As wastewater flows through the screen, large suspended solids are intercepted by the bars. Driven by the chain mechanism, the rake teeth continuously lift the retained debris to the top of the screen, where it is automatically discharged into a conveyor or waste container through a self-cleaning or reverse scraping mechanism. This ensures uninterrupted removal of solid waste.
Main Components
Frame: Made of stainless steel or carbon steel with anti-corrosion treatment for structural strength.
Bar Rack: The spacing between bars can be customized (typically 1-50 mm) based on treatment requirements.
Rotary Chain System: Made of corrosion-resistant materials to ensure long-term operation.
Rake Teeth: Precisely matched with the bar rack for efficient debris removal.
Drive Unit: Composed of a motor and reducer, equipped with overload protection.
Rake Cleaning Mechanism: Automatically removes retained solids for continuous operation.
Features
Fully automatic and continuous operation; suitable for unattended systems.
Adjustable bar spacing to meet various wastewater treatment conditions.
Smooth transmission, low noise, and low energy consumption.
Compact design with a small footprint and easy installation and maintenance.
Optional control system for remote monitoring and automatic backwashing.
