Abstract
A scrapping system of used-automobiles includes a reusable parts collecting station, a liquid collecting station for collecting liquids including fuel, oil and coolant, a prearrangement station for collecting chlorofluorocarbon, batteries, seats, tires, etc., a functional parts collecting station for collecting a suspension device, a non-ferrous metal parts and resin parts collecting station for collecting motors, harnesses, instrument panels, bumpers, etc., and a pressing station for pressing a body of the used-automobile which has been processed in the above stations. The stations are sequentially arranged.
Claims9
A method of recycling used-automobiles, comprising the steps of:
- collecting reusable parts including exterior parts from a used-automobile;
- collecting liquid from said used-automobile;
- prearranging the used automobile to facilitate subsequent collecting operations;
- collecting functional parts from said used-automobile;
- collecting non-ferrous metal parts and resin parts from said used-automobile to an extent such that a remaining Cu content is in a range of about 0.2 to about 0.04 weight percent and such that a remaining Sn content is in a range of about 0.01 to about 0.0013 weight percent based on 100 weight percent of total metal weight remaining in said used-automobile after said step of collecting non-ferrous metal parts;
- and
- pressing a body of said used-automobile which has been subjected to said steps, wherein said steps are sequentially carried out in a continuous straight line to directly recover collected parts and a body of the used-automobile without shredding of the used-automobile, and a recycling rate of said used-automobile yielded by said collected parts directly collected from said used-automobile and said body of said used-automobile after collecting parts is adapted to be in the range of 85 to 97 weight percent.
