ABSTRACT:
An automatic compactor-crusher for processing spent aerosol spray cans safely depressurizes, evacuates, and crushes cans for subsequent environmentally sound disposal and/or recycling. Fluid residue is safely captured within a reservoir. A vertically upright, supporting frame secured to a floor in the work area supports a telescoping can receiver assembly. The receiver assembly matingly receives cans for processing. A hydraulic crusher assembly located on top of the frame compresses cans against the receiver assembly with an extensible ram. The receiver assembly comprises a tubular sleeve which coaxially receives a displaceable cylinder. A rigid union at the bottom of the sleeve limits travel of the cylinder, and establishes a fluid flow path into a holding tank. A rigid valve guide projecting from the union mounts a fluid control valve for selectively blocking fluid escape from the receiver, and a rigid, canpiercing lance which punctures cans after sufficient ram displacement. The valve stem mounts a tubular receptacle which coaxially mates with the spray can actuator nozzle. After sufficient ram movement the can will be forcibly punctured by the lance. Downward movement of the sleeve is limited, and further ram movement will forcibly compress the can when sleeve travel stops and ram movement continues.
