US 2006/0076276 A1 · Method and apparatus for sorting out shredder waste

Abstract

An apparatus and a method for sorting out shredder waste allows for lower sorting cost and higher sorting accuracy to be achieved. Shredder waste is fed into a hopper to untangle it. The untangled shredder waste is quantatively supplied into a separating duct wherein the shredder waste is subjected to steam by a steam injector so as to be further untangled. The shredder waste that has been further untangled in the separating duct is carried, while being agitated, into a striker. In the striker, the shredder waste is struck by chains that swing as a rotating shaft rotates, so that harness waste or the like is separated from the shredder waste. The separated harness waste or the like is transferred onto a conveyor through an outlet. On the conveyor, the harness waste is separated from heavy materials, such as rubber and rigid plastics.

Dependent claims

An apparatus for sorting out shredder waste, comprising:

a hopper which has adjacently disposed spiral shafts rotating in opposite directions from each other and into which shredder waste is fed;
a separating duct having a rotary drum which conveys the shredder waste supplied through an outlet of the hopper while agitating it and which has spiral projections on the inner surface of a wall thereof;
a steam injector that is connected to the separating duct and which emits steam toward an entire inlet of the separating duct connected to the outlet of the hopper;
and
a rotary striker that has, in an upper portion thereof, an inlet for receiving shredder waste discharged from the separating duct and an outlet through which a part of the shredder waste is discharged, a rotating shaft which is vertically provided under the inlet and the outlet and to which ends on one side of which are connected a plurality of chains that rotates with the rotating shaft, and another outlet provided below the chains.

2 more elements

A method for sorting out shredder waste produced by scrapping cars including harness waste, comprising:

a first untangling step for untangling the shredder waste using screw shafts disposed in a hopper into which the shredder waste is fed, said screw shafts being disposed adjacently in parallel and rotating in opposite direction from each other;
a second untangling step for untangling the shredder waste by spraying steam onto the shredder waste discharged from the hopper;
a third untangling step for untangling the shredder waste using a rotary striker by striking the shredder waste with a plurality of chains swinging around a rotating axis of the rotary striker.
