What Are The Types Of Mechanical Bar Screen

Solid Liquid Separator June 27, 2025 Mechanical Bar Screen

Structure:
Drive unit + synchronized chains + bar rack. The rake moves along guide rails to remove debris.
Application Scenarios:
Deep pit wastewater treatment (e.g., collection wells); highly effective in removing long fibers and ribbon-like materials.
Advantages:
All transmission components are above the waterline, simplifying maintenance and saving installation space.
Limitations:
Prone to chain blockage by debris; corrosion resistance requires improvement.

Innovative Features:
Dual wire rope drive + rake lifting guide rail design, equipped with overload alarm system.
Application Scenarios:
Small- to medium-scale wastewater treatment plants with a capacity of 150,000–250,000 m³/day.
Advantages:
Capable of handling high sand content wastewater; self-locking mechanism prevents secondary pollution.
Limitations:
Complex mechanical structure; relatively high maintenance cost.

Technical Features:
Arc-shaped bar rack + rotary rake arm, integrated with ultrasonic level control.
Application Scenarios:
Shallow channel screening, especially suitable for wastewater containing grease or oils.
Advantages:
Compact structure with automatic slag discharge device.
Limitations:
Requires high manufacturing precision; susceptible to deformation from water flow impact.

Core Design:
Enclosed chain drive + dual bar racks (front/rear positioning).
Application Scenarios:
Deep well applications in water supply and drainage projects; excellent for particle size-based interception.
Advantages:
Solid-liquid separation efficiency up to 95%; adjustable flow velocity across the screen (0.6–1.0 m/s).
Limitations:
Relatively high energy consumption; not suitable for wastewater with high fiber content.
