Wastewater Automatic Raking Screen Pretreatment Screens & Screen Handling Equipments

Automatic Raking Screen is simple to retrofit into existing installations. It combines a rash rake, conveyor and a debris loading system directly into a dump skip or trailer. It provides simple and fully automatic operation for 24-hour coverage in case of night-time screen blockages with an open overhead construction to maintain an uncluttered screen deck. Automatic Raking Screen moves along a monorail track set above the intake and dump areas with traveling speeds between 10-30m/min. For installation with heavy debris loading which requires a long track length, a dual travel speed of 30-60m/min would be specified to reduce the overall cleaning cycle time.

The Automatic Raking Screen travels to the designated screen area at the start signal and stops over its first pick-up point. The gripper descends to the bottom of the screen, collecting debris in its jaws. The cylinders close the gripper and the hoist raises it to the trolley. The trolley and gripper return to the dump area where the gripper opens, releasing debris directly into the hopper, trailer or another dumpsite, eliminating the need for additional handling. The automatic raking screen afterward moves back to the second pick-up point at the screen, continuing the cycle until the selected screen area is clean.

Automatic Raking Screen does the work of three conventional machines a trash rake, conveyor and debris-loading system. There is no need for multiple rakes, conveyor belts or manual handling of debris, substantially reducing costs. Debris is loaded directly into skip or trailer, eliminating the need for additional handling. Open, overhead construction means the screen deck is clear.
