Many people ask the editor, what is the band screen? What is the process of band screen? Below I will introduce it to you.

Working principle:

The geared motor drives the sprocket to rotate, and the sprocket drives the mesh plate to rotate continuously; the sewage enters the grille from the water inlet and is filtered by the mesh plate. After filtering, the water flows to the outside of the mesh plate, and the dirt is trapped on the inner surface of the same plate. The belt is continuously rotated to the top; the backwash system washes the outside of the washing plate, and the dirt is washed into the slag collecting tank under the action of the washing water, and flows out of the sewage outlet together with the washing water.

Composition:

The band screen consists of six parts: frame, drive system, screen system, backwash system, slag removal system and electric control system.

1. Rack part

The main material is 304 stainless steel.

2. 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.

3. Stencil system

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 extending its service life while protecting the rail surface.

The chain puller is a polyethylene injection molded part with a unique structure design. It can well seal with the end face of the guide rail during the rotation of the screen 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. It adopts non-metallic injection parts to reduce the weight of the whole machine. At the same time, the modular design is beneficial to the installation and maintenance of the stencil system.

Performance characteristics:

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

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

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

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

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

6. Smooth operation, light vibration and low noise.
