Rotary drum screens is widely used in municipal sewage, industrial wastewater, food processing industry, paper industry and other sewage treatment projects. The equipment salvages and removes the scum, staple fibers and suspended solids from the water intake, and then squeezes them to dry, press and dehydrate them and discharges them. It is suitable for high precision treatment and sewage treatment occasions with small gap and shallow canal depth.

Drum screens are mostly designed as fine screens to intercept small solid wastes in water; Drum screens use cylindrical screen as screens to intercept screens slag, unload slag through rotary screens and flushing device, and screens slag is conveyed and pressed through screw mechanism for dewatering; and the horizontal surface is 35 degrees installed in the channel, sewage flows into the drum from the end of the drum and water flows through the screens slot of the screens network. The solid waste is filtered in the grid basket. The cleaning arm with rake teeth clears the gap of the grid when it moves around. The rake teeth extend into the grid and take out the solid.

The drum screens is different from the inner inflow screens. When the cleaning arm is at the highest point, the garbage is removed from the rake teeth through the washing of water and the role of the slag baffle, and falls into the screw conveyor of the garbage collection device. During the conveying process, the garbage is dehydrated through the role of variable pitch, and the compressed area at the top is squeezed out, while the squeezed water is returned to the water channel, and the garbage is finally sent to the container or. Subsequent equipment, and then processing.

The drum screens can adjust the running interval of the equipment according to the user's need to realize periodic operation, according to the liquid level difference before and after the screens, and has manual control function to facilitate maintenance. Users can choose according to different work needs. Because the structure design of the equipment is reasonable, it has a strong self-purification ability when the equipment is working, and there will be no blockage, so the daily maintenance workload is very small.www.khnwatertreatment.com
