TRASH RAKES - CV TYPE (SCRAPER)

PURPOSE

To remove incoming, larger-sized debris (branches, seaweed, plastics, refuse, large jelly-fish, etc.) in small and medium capacity plants.

DESCRIPTION

CV rakes are installed at the inlet of screening plants, ahead of the travelling band screens or the drum screens.

 

The water flows across the vertical bar rack where the debris are arrested.

 

When cleaning is required, the rake which is normally parked open above deck, travels down the wall guides and tilts when reaching the bottom. The rake engages the bar rack, travels up collecting all arrested debris in the process. On reaching deck level, the debris are swept off the rake by the cleaning arm, into the deck trough or trash baskets.
