Introduction

Rotary Rake Screen is a kind of water treatment equipment which can continuously and automatically intercept and remove all kinds of sundries in the fluid. Tap water industry, power plant inlet, but also as a textile, food processing, papermaking, leather and other industries in the wastewater treatment process of the pre-stage screening equipment, is currently one of the most advanced solid liquid screening equipment.

Operating principle

Rotary Rake Screen is a unique rake tooth factory assembled into a group of rotary grid chain. Driven by the motor reducer, the rake tooth chain rotates in the direction of reverse current.

When the rake tooth chain runs to the upper part of the equipment, due to the guidance of groove wheel and curved rail, the relative self-cleaning movement is generated between each group of rake teeth, and most solid materials fall down by gravity. The other part relies on the reverse movement of the sweeper to clean up the debris stuck to the rake teeth.

The rake tooth chain is similar to the grid according to the direction of water flow. The gap of the rake teeth assembled on the rake tooth chain axis can be selected according to the service conditions. When the rake teeth separate the solid suspended object in the fluid, it can ensure the smooth flow of water. The whole process is continuous or intermittent.

Characteristics

The biggest advantage of the equipment is high degree of automation, high separation efficiency, small power consumption, no noise, good corrosion resistance, in the case of no one to care to ensure continuous and stable work, set overload safety protection device, in the equipment fault, will automatically shut down, can avoid the equipment overload work. The equipment can adjust the operation interval of the equipment arbitrarily according to the needs of the user to realize periodic operation. It can be controlled automatically according to the liquid level difference before and after the grid. And has the manual control function, in order to facilitate maintenance. Users can choose according to different work needs.

Due to the reasonable structure design of the equipment, when the equipment is working, it has a strong self-cleaning ability and will not cause blockage, so the daily maintenance workload is very small.
