Product Description

The main structure of the inflow fine mesh plate type screen: main frame, filter plate, conveyor chain and chain wheel, equipment sealing element, flushing device and brush cleaning device, slag collecting hopper, screen shell, baffle, drive motor, etc. It is generally classified into screen, fine screen and membrane screen from the filtration precision.

The inflow fine mesh plate type screen is made of all stainless steel material, and the whole machine is treated by pickling and passivation to ensure the normal service life of the main structure is not less than 20 years.

Working Principle

The inflow fine mesh plate type screen is installed in the sewage channel at a 90° angle, and the sewage to be treated flows in from the center of the screen, and the filtered sewage is discharged from both sides of the mesh plate.

The suspended organic slag such as fibrous materials, plastic sheets, leaves, hair, and domestic garbage is trapped on the inner wall of the filter plate and continuously accumulated and covered. When a certain clogging rate is reached, the set liquid level difference is formed in the front and back of the screen, and the driving motor will drive the conveyor chain wheel and chain to lift the plate that retains a large amount of slag to the top of the screen.

At the same time, flush pipe and cleaning brush start to work and clean the plate by pressured washing water. According to the particularity of the water quality, a cleaning brush is often added to the fine screen to assist in cleaning the plate. The rinsed slag-water mixture falls into the slag collection hopper and is discharged to the slag presser for dewatering. The cleaned filter plate is circulated into the channel and continue to work.

Advantages

♦ The inflow fine mesh plate type screen is not sensitive to the depth of the channel and can be installed and applied conveniently.

♦ Installed at a 90° angle, double side flow filtration, large filter area, small footprint.

♦ Insensitive to sand in sewage.

♦ High-strength mechanical structure design, suitable for high-flow impact, long service life.

♦ Set the rake on the plate at a certain distance, which has a strong ability to intercept the slag and high removal efficiency.

♦ Flushing water and cleaning brush complement each other to prevent fiber from perforating and winding the grid.

♦ Compared with other fine screens, it has excellent cost performance.

♦ Adapt to various installation environments and operating environments in the field of wastewater treatment.

♦ Large flow, small head loss.

♦ Closed treatment to prevent odor spill.
