Working principle

1. The Rotary Drum Screen should be installed in the water channel at 35 degrees from the horizontal plane;

2. Sewage flows into the drum from the end of the drum, which flows out through the grid gap of the grid. Solid waste is filtered in the grid basket, and cleaning arms with rake teeth are on the circumference, during the movement of the grille, the rake teeth reach into the grid and take out the solids;

3. When the cleaning arm is at the highest point, the garbage is removed from the rake teeth by the flushing of water and the role of the slag block, and it is dropped into the garbage collection device;

4. In the spiral conveying bucket of the collecting device, during the conveying process, it is dewatered by the function of changing the pitch, and is squeezed out in the uppermost compression zone, and the squeezed water is returned to the water channel, and the garbage is finally sent to the container or subsequent equipment for processing.
