Swing-type格栅污物清除机

Product Description

The HRHG series of rotary grille screen cleaners is a specialized water treatment equipment capable of continuously and automatically intercepting and removing various shaped debris from fluids, suitable for use in urban sewage treatment.

Working Principle

The HRHG series rotary格栅screening cleaner is composed of a unique assembly of rake teeth forming a rotating grille chain. Driven by a motor reducer, the rake teeth chain rotates against the water flow, collecting debris floating on the surface. As the chain reaches the top of the equipment, guided by the groove wheel and curved track, each rake tooth undergoes a relative self-cleaning motion, with most solid matter falling off due to gravity. The remaining debris is then cleaned off the rake teeth by the sweeping action of the cleaner in the opposite direction.

Rake chain, similar to a grate, follows the water flow direction. The gap between the rakes on the rake chain shaft can be selected according to the operating conditions. After the rakes separate solid suspended matter from the fluid, it ensures smooth water flow. The entire working process is continuous, or it can be intermittent.

Product Features

The equipment boasts high automation, high separation efficiency, low power consumption, noiseless operation, and excellent corrosion resistance. It can ensure continuous and stable operation even without supervision. Moreover, it is equipped with a mechanical overload safety protection device. In the event of a fault, the shear pin breaks, preventing the equipment from overloading and damaging its components.

This equipment can be adjusted to any operational interval as per user requirements, enabling periodic operation; it can automatically control the start and stop of the equipment based on the liquid level difference before and after the grate; and it also features manual control for convenient maintenance. Users can freely select according to different operational needs.

Due to the reasonable structural design of the equipment, it possesses strong self-cleaning capabilities during operation, preventing clogging and requiring minimal daily maintenance efforts.
