  • Conveyor belt cleaning apparatus
    Patent number: 5117967
    Abstract: A free-standing cleaner (10) for conveyor belts (60) constitutes a tank (12) for holding fluid and having a removeable pad (22) attached across its bottom surface (14). Nozzles (20) in the bottom surface deliver the cleaning fluid to the pad (22). One longitudinal end (18) of the tank depends from the majority of the bottom surface (14) and hooks over the upstream end of the conveyor for anchoring the tank (12) against movement with the conveyor belt (60). Tandem tanks may be joined to the downstream end of the first tank for applying multiple cleaning fluids to the belt (60).
