Mechanical Fine Screen Description

The mesh plate stepped grille is a kind of fine grille, which has good adaptability and removal effect for fine particles and fibrous garbage in sewage, so it is widely used in the upgrading and transformation of medium and large sewage treatment plants and the process of strengthening pretreatment. middle.

The mesh plate ladder grille is mainly composed of a frame, a perforated mesh plate chain, and a transmission mechanism. Among them, the perforated mesh plate is installed on the heavy-duty traction chain, and the filter surface is formed in steps. After the sewage passes through the filter surface, the garbage larger than the diameter of the mesh will be trapped on the filter surface, and will be lifted out of the water surface with the movement of the mesh plate. The filter surface is unloaded to achieve decontamination.

Mechanical Fine Screen Composition

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 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.
