Abstract

The invention discloses a paint removing device for painted granular plastics. The paint removing device comprises a quantitative feeder, a friction separator, an air blower, a spindle motor and dusty-air purifiers. The air blower is connected into a paint removing device body by a hollow rotary shaft, the spindle motor drives the hollow rotary shaft via a belt pulley, painted materials are quantitatively conveyed to a screw conveyor from a feed inlet via the quantitative feeder, the screw conveyor consists of the hollow rotary shaft and screw blades, the painted materials are parallelly propelled by the screw conveyor to an external cavity of the high and low-pressure friction separator to be subjected to friction separation, the high and low-pressure friction separator comprises a coaxial friction tube and a netted dust removing sieve plate, and paint film dust and finished plastic granules are separated and then are respectively fed into accumulated dust boxes. Crushed plastic granules are quantitatively fed into the friction cavity to be subjected to friction paint removal, and the paint film dust and the clean granules are separated from one another and are respectively collected, so that waste plastics of automobiles are recycled, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to recycling and processing of scrapped plastic parts, in particular to a device for recycling and processing plastic parts with paint, especially scrapped plastic parts of automobiles, so as to remove paint and realize reuse. Background technique [0002] At present, with the rapid development of my country's automobile market and the increasing trend of private car ownership, the number of scrapped bumpers and other plastic parts produced by damaged and scrapped vehicles is considerable. The surface of automobile bumper is difficult to recycle due to its unique and firm paint layer that cannot be removed. It has been treated as waste products for a long time, causing environmental pollution. [0003] The existing paint removal methods include laser removal method and chemical treatment method. The cost of laser removal method is too high. At present, it can only be used for laboratory processing or small batch processing, and in...
