Mechanical Rotary Bar Screen
The mechanical rotary bar screen (rotary screen cleaner) intercepts and lifts debris from wastewater through continuously rotating rake-tooth chains, achieving automatic debris removal. With a simple structure, reliable operation and high cleaning efficiency, it is widely used in the pretreatment of municipal sewage and industrial wastewater, and is essential screening equipment for sewage lifting pump stations and wastewater treatment plants.
The mechanical rotary bar screen, also known as a rotary-type bar screen (rake screen), is a continuously operating screening device. Through the rotating rake-tooth chain, it intercepts and lifts floating matter and suspended solids out of the water, achieving automatic screen cleaning. It is important equipment in the pretreatment stage of sewage treatment.
Working principle: driven by the drive device, the rake-tooth chain rotates continuously. As the rake teeth move from bottom to top, they intercept and carry the screenings out of the water. At the top, the screenings are automatically discharged into a conveying trough, achieving continuous interception, lifting and discharge.
The equipment runs continuously with high screen-cleaning efficiency. The rake-tooth spacing can be selected as needed, offering flexible screening precision. It has a simple structure, reliable operation and convenient maintenance, with corrosion-resistant stainless steel construction and automatic control that enables remote monitoring.
It is widely used for pretreatment screening in municipal sewage treatment plants, sewage lift pump stations, industrial wastewater treatment stations and various sewage treatment projects.
