Rotary Arm Curved Bar Screen
The working principle of the rotary arm curved bar screen involves a drive unit that rotates the rake arm to lift and remove debris retained on the curved bar screen. A scraper is used to clean off the debris from the rake arm.

The rotary arm curved bar screen is a type of screening equipment suitable for use in shallow channels at small to medium-sized wastewater treatment plants.

Wire Rope Traction Type Bar Screen Cleaner
The wire rope traction screen cleaner operates through a drive system that moves two steel wire ropes, pulling the rake along a guide rail made of channel steel. The rake descends by gravity to the bottom position, where a self-locking pin hits a stop block and releases, allowing the rake to swing downward. The rake teeth insert into the gaps between the bars, and the rake is then pulled upward by the wire ropes to remove debris. As the rake reaches a certain height, a lifting rail gradually raises the rake, and a scraper automatically discharges the collected debris into the discharge trough.

This type of bar screen is also suitable for small to medium-sized wastewater treatment plants.
