APPARATUS FOR RECYCLING TREATMENT OF WASTE HOUSEHOLD ELECTRIC PRODUCT

摘要

PURPOSE: To sort and recover a polypropylene resin having purity capable of being again recycled as a polypropylene resin from a general-purpose polypropylene resin used in a household electric product in the largest quantities, in an apparatus for the recycling treatment of a waste household electric product, for performing the water gravity concentration of a plastic material or the like by material from the crushed matter of the waste household electric product becoming waste. CONSTITUTION: The supply raw material from a first raw material supply part 43 for supplying the crushed matter of the waste household electric product or the crushed matter and sorting water is sorted into at least two kinds of crushed matters on the basis of the specific gravity difference between the crushed matters by a sink-and- float type water gravity concentration machine 42 and centrifugal force is allowed to act on lightweight matter and sorting water among at least two kinds of sorted crushed matters by a vertical centrifugal water gravity concentration machine 44 to again sort crushed matter sunk in water and crushed matter floating on water. The sorting water used in the vertical centrifugal water gravity concentration machine 44 is circulated to the upstream side of the sink-and-float water gravity concentration machine 42 by a second pump 51.
