Grid Grille Coarse Mechanical Perforated Plate Fine Screen

Mechanical Fine Screen Description

At present, the installation and use of mesh grille equipment by manufacturers will not take up too much space, and the structure of the equipment is simple, so the maintenance method in the process of work is very simple, which can reduce the installation cost for the manufacturer. The equipment will be debugged before leaving the factory to ensure the production quality of the equipment.

Mechanical Rake Screen is a solid-liquid separation device which has been widely used in municipal wastewater treatment plant,pre-treatment device for domestic effluents, municipal rainwater & sewage pump station. It is regarded as the ideal solid-liquid separation equipment in water treatment field.

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 Parameter

Mechanical Fine Screen Advantage

The removal rate is high, which can effectively remove fibrous objects such as hair;

The backwash water will remove the dirt trapped on the screen, and will not fall into the filtered water to avoid secondary pollution;

The stencil is made of non-metal injection molded parts, which are resistant to wear and corrosion;

There are no transmission parts underwater, no maintenance is required, and it is more convenient to repair and maintain;

The wear parts are completely standardized, easy to replace and easy to operate;

Smooth operation, light vibration and low noise.

Mechanical Fine Screen Technology

Rack section

The main material is 304 stainless steel.

Drive System

The drive sprocket adopts PA1010, which has excellent wear resistance and self-lubrication, and has good rigidity, mechanical strength and medium stability. use.

The guide rail is made of high molecular polyethylene material, which has good wear resistance and self-lubrication.

Stencil System

Mesh grid CF type

The inner sleeve of the slewing wheel is made of nylon injection molded parts, and the outer sleeve is treated with glue to improve wear resistance. Since the adhesive layer has good elasticity. Greatly prolongs its service life while protecting the rail surface.

The chain lever is a polyethylene injection molded part with a unique structure design, which can well seal with the end face of the guide rail during the rotation of the mesh plate, preventing dirt from entering the guide rail, causing water pollution after filtration and guide rail wear.

The stencil is the core component of the entire stencil grille. The use of non-metal injection molded parts reduces the weight of the whole machine. At the same time, the modular design is conducive to the installation and maintenance of the stencil system.

 

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.
