4. Construction and Working Process

Construction

It consists of drum screen, support roller unit, drive mechanism unit, backwash cleaning system, unloading mechanism, cover plate assembly, access door, frame and filtrate collection bucket.

Working Process:

The drum is horizontally supported by four wheels, and is driven by TEFC reducer, anti-corrosion roller chain and stainless-steel sprocket. The spray system automatically sprays clean water. Its integrated design, sturdy construction, and high-quality stainless-steel materials ensure that the equipment can run for long periods of time with low energy consumption without trouble, and is easy to maintain. The overflow trough extends to the inside of the drum, and raw water flows in from the overflow trough, and is evenly injected into the inner wall of the drum through the distribution of the weir. The filtered raw water is guided to the central drainage area through the floor deflector and flows into the next sewage treatment unit; the slag in the raw water is blocked on the inner surface of the drum filter, and is discharged through the inner wall as the drum rotates The slag is conveyed spirally to the tail slag hopper. As the drum head rotates, the entire screen surface can be continuously or intermittently sprayed by an external spray system.
