The Brackett Bosker automatic raking screen is designed for a wide range of applications where highly effective bar screen cleaning is necessary, including power stations (nuclear, fossil and hydro), flood defence and storm drainage pumping stations, and industrial pumping stations. Simplicity of design and efficient debris handling make the Brackett Bosker raking machine the ideal solution for cost-efficient cleaning of single or multiple bar screens.
Ovivo customizes every automatic raking screen to site- and application-specific parameters. It is simple to retrofit an existing installation, with usually no need for expensive civil modifications.
The Brackett Bosker 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 a skip or trailer, eliminating the need for additional handling. Open, overhead construction means the screen deck is clear. Our engineers can include a curved overhead monorail track if required, allowing access to multiple screens or remote dump sites. Operation is fast, simple and fully automatic, providing 24-hour coverage in case of night-time screen blockages.
The Brackett Bosker automatic trash rake travels along a monorail track over the screen and dump areas. Travel speeds are between 10-30m/min. At installations where there is a long track length and a heavy debris loading, a dual travel speed of 30-60m/min would be specified to reduce the overall cleaning cycle time.
The Brackett Bosker automatic raking screen then moves back to the second pick-up point at the screen, continuing the cycle until the selected screen area is clean.
Each custom engineered Brackett Bosker raking machine consists of the following:
