Mechanical Perforated Plate Fine Bar Multi Rake Mechanical Screens

Mechanical Fine Screen Description

The fine grille decontamination machine is assembled into a set of rotary grille chains by a unique rake tooth factory. Driven by the motor reducer, the rake tooth chain rotates against the direction of the water flow. When the rake tooth chain runs to the upper part of the equipment, due to the guidance of the sheave wheel and the curved rail, a relative self-cleaning motion occurs between each group of rake teeth, and most of the solid materials fall down by gravity. The other part relies on the reverse movement of the sweeper to clean up the debris stuck on the rake teeth. According to the direction of water flow, the rake tooth chain is similar to the grille, and the rake tooth gap assembled on the rake tooth chain shaft can be selected according to the usage conditions. When the rake teeth separate the solid suspended matter in the fluid, the water can flow through it smoothly. The whole working process is continuous or intermittent.

Mechanical Fine Screen Composition

Parts of the fine grille of the inner inflow mesh plate frame;
Drive System;
Stencil System;
backwash system;
Division system and Electronic control system;
 

The geared motor drives the sprocket to rotate. The sprocket drives the mesh plate to rotate continuously; the sewage enters the grille from the water inlet, and passes through the mesh plate to overspeed. The water flows to the outside of the screen plate, and the dirt is left on the inner surface of the same plate. With the continuous rotation of the screen plate, it helps to the original part: the backwash system flushes the outside of the screen plate, and the dirt is washed to the receiving channel under the action of the flushing water. Feel free to check the flushing water from the well to the sewage outlet.

Mechanical Fine Screen Technology

The driving device is under the drive of cycloidal pin gear speed reducer or helical gear reducer, with low noise, neat structure & stable operation.

Integrated framework, with good rigidity and convenient installation and maintenance.

Two specifications for rake tooth, pitch t=150mm for coarse screens, pitch t=100mm for fine screens.

Easy to operate. It can be direct or remote controlled.

Mechanical shearing bolt & over-current protection are set to ensure safe running.

While the width of equipment over 1500mm, parallel machines are adopted to ensure the integrated strength of equipment.

Mechanical Fine Screen Application

It is a high-efficiency fine grille decontamination equipment that combines pollution blocking and decontamination.

It is suitable for large, medium and small pump stations as fine grilles to intercept and remove floating objects in the water, such as: weeds, paper, cigarette butts, melon seeds, fibers, hair, etc.

This model has a high dirt capture rate , the effective implementation of the subsequent treatment process.
