ABSTRACT:
Waste thermoplastic resin film is cleaned to reclaim raw material for subsequent recycling by crushing a mass of the waste film into pieces and then feeding the pieces onto a moving mesh conveyor immersed in a wash tank which is filled with a cleaning liquid; the liquid being at a temperature sufficient to soften the pieces. Cleaning is promoted by irradiating the pieces on the conveyor with ultrasonic energy from positions located on opposite lateral sides of and just above the upper surface of the conveyor while simultaneously forcing liquid in the tank to flow in the same direction as the conveyor while directing jets of additional liquid into the tank in the opposite direction to produce a forced circulatory flow pattern within the tank.
