For the grille decontaminator, there are many types of equipment, which are used in different decontamination operations, the drum grille is one of them. Rotary drum grille is mainly used in sewage treatment and industrial wastewater treatment projects to remove small floating matter in water. It is often used after rough grille. It is mainly composed of reducer, screen, screw shaft, cleaning device, bracket, slag hopper and other systems.

The grille rings in the drum grille basket are arranged in the shape of steps and form an angle of about 55 degrees with water flow. Because of the formation of baffles, many pollutants, such as fibers, bristles, paper, plastic fragments and sanitary articles, can be separated even if their thickness is less than the gap of the grille.

Basket structure enlarges the grille filter surface immersed in water, and new grille filter surface is constantly generated by rotating cleaning, so the accumulation plane in front of the grille in the channel is very low. The cylindrical structure of the grille basket greatly increases the filtering area of the grille immersed in water, increases the flow rate and reduces the head loss.

In the case of narrow channel width, the separation effect can be improved by using fine grids. Maintenance work is reduced to a certain extent by means of non-maintenance manufacturing: no refueling is needed at the rotating point, and the refueling times of motor-driven machinery are very few. Just use the regular flushing device of the water pipe.www.khnwatertreatment.com
