Main functions of rotary screen cleaner

It can continuously separate suspended solids in sewage, so it has high efficiency, stable operation, small water level difference before and after the grid, and low operation noise; Simple structure, convenient operation and easy maintenance; The sliding bearings of the rotary screen cleaner are made of nylon material, corrosion resistant and oil-free. The parts of the rotary grid cleaner are made of stainless steel, which has corrosion resistance and strength, and can be used for a long time even in harsh environment.

(1) There are two types of grille: artificial grille and mechanical grille. In order to avoid the toxicity of pollutants to people, reduce the labor intensity of workers, increase work efficiency and achieve automatic control, mechanical grille should be used as much as possible.

(2) The specific form and material of the grid shall be confirmed according to the water quality characteristics of the sewage, such as the high and low pH value and the size of the solid. The material is mostly 304 stainless steel, and 316 stainless steel can be selected for high requirements.

(3) Large-scale sewage treatment plants generally need to set two grids and one screen. The spacing of grid bars should be determined according to the type, flow, type and size of representative sundries of sewage and other factors, which not only meets the requirements of pump construction, but also meets the requirements of subsequent water treatment structures and equipment.

(4) Its parameter size, size and so on are customized according to the design requirements. Generally, manufacturers provide customized production!

(5) The grid is generally installed at the water inlet of the pump station, which is located at the throat. For safety, there should be standby units or other means to ensure the maintenance of the grid without stopping the water supply.

(6) The rotary screen dirt remover is used to protect the power equipment. The mechanical screen is generally installed in the well-ventilated screen room. Large and medium-sized screens should be equipped with lifting equipment to facilitate equipment maintenance.
