Rake-type rotary bar screen cleaner

A rake-type rotary bar screen cleaner is a mechanical screening device widely used in water treatment and wastewater pretreatment systems. It is designed to remove solid debris from influent water, helping maintain stable flow conditions in downstream processes. The equipment operates using rotating rake teeth that continuously clean the surface of a bar screen, lifting and discharging accumulated solids such as plastics, leaves, and other coarse materials. This ensures consistent screening performance in municipal and industrial water treatment applications. Constructed with durable stainless steel, the system offers strong corrosion resistance, making it suitable for long-term operation in harsh and humid environments. Its design supports reliable automatic cleaning with reduced manual maintenance requirements. Rake-type rotary bar screen cleaners are commonly installed in pumping stations, wastewater treatment plants, and intake structures where efficient solid-liquid separation is required at the preliminary treatment stage. Overall, this equipment provides a dependable solution for bar screen cleaning in water treatment systems, improving operational stability and supporting continuous flow management in screening processes.

Overview

The HG series rake tooth rotary grille decontamination machine (also known as solid-liquid separator) is a device that can continuously and automatically remove various shapes of debris from fluids, aimed at solid-liquid separation. It can be widely used as a specialized equipment in urban sewage treatment, drinking water industry, and power plant inlet, and is also an essential specialized equipment in the production processes of industries such as textiles, food processing, papermaking, and leather. It is an ideal solid-liquid screening device.

Model Description

Application Fields

This equipment is made of special shaped rake teeth from ABS engineering plastic, nylon, or stainless steel, assembled in a certain order to form a closed rake tooth chain, with its lower part installed in the water body of the inlet channel. When the drive system drives the sprocket to rotate uniformly and directionally, the entire rake tooth chain moves from top to bottom, carrying solid debris out of the liquid, while the fluid flows through the gaps of the rake teeth, and the entire working state continues. Due to the special knotted shape of the rake teeth, the rake tooth chain carries debris to the upper end and generates a relative self-cleaning motion between the front and rear rake rows before reversing, promoting debris to fall off due to gravity. At the same time, a pair of rubber plate brushes set behind the equipment ensures that each rake tooth row is cleaned when it reaches that position.

Performance Characteristics
1. It has self-cleaning ability, compact structure, stable operation, and no noise.
2. The debris is supported by the bent hooks of the rake teeth, preventing it from falling. When it flips to the top, it is easy to unload the debris.
3. Simple operation, capable of manual and automatic operation, and can also achieve remote control.
4. Equipped with dual overload protection for mechanical and electrical systems.
5. The rake teeth can be made of ABS, nylon, stainless steel, etc., to meet different needs.
