Abstract
A cleaning apparatus for cleaning mechanical workpieces, such as bearings, comprises a reservoir for containing a cleaning liquid, a stationary conveyor mechanism partially immersed in the cleaning liquid, and a high frequency vibration source disposed in proximity to and near the bottom of the reservoir. Responsive to the vibration source transmitting vibratory energy via a coupling medium to the cleaning liquid, the workpieces are simultaneously conveyed along the conveyor mechanism and cleansed in the cleaning liquid.
Claims15
A cleaning apparatus comprising:
- a reservoir adapted to contain a solvent for cleaning workpieces;
- a coupling liquid disposed in contact with said reservoir at the exterior thereof;
- conveying means arranged to cause a portion thereof to be disposed in said reservoir for contact with said solvent and causing workpieces supported by said portion to be exposed to said solvent;
- a source of high frequency vibratory energy disposed in proximity to the bottom of said reservoir and said portion of said conveying means, said source adapted when energized to impart high frequency vibrations via said coupling liquid to said reservoir and the solvent to cause cavitation in said solvent, and
- said conveying means being shaped to cause workpieces supported on said conveying means to advance themselves along said conveying means responsive solely to the combined action of gravity and cavitation produced in said solvent.
