Apparatus for the separation of wire and its insulating material and recovering these as raw materials

Claim 1

A device for separating wire from its insulating material, comprising in combination: a. carrying means (2) for carrying a bundle (3) of wires in a flow direction to a cutter (1); b. a cutting mechanism in the cutter (1) for cutting the bundle (3) of wires to a desired length; c. an oscillating feeder (4) adjacent said cutter (1) which supplies the wire material (3'') cut to desired lengths; d. a rapid cooling unit (6) with a circulating pipe, fed by said feeder (4), including a rotatable screen-shape levelling unit (5) which levels passing material to a uniform thickness; e. an elongated insulating box (7) with an endless net-like conveyor (8) carrying the cut wire material (3'') within said box to a terminal; f. an injection nozzle (12) at the rear end of said box atomizing a low-temperature coolant flowing therein from a storage tank (9) and spraying it onto the wire material (3'') near the rear end of said insulating box (7), including a valve (1) and a connecting pipe (11) said rapid cooling unit (6) extending from the forward to the rear end of said insulating box (7) and circulates cooling gas to precool the wire material (3''); g. a separating device (17) at said conveyor terminal in which the wire material (3'') cooled by said rapid cooling unit (6) is separated into insulating material (60) and core material (59) such as copper wire and which includes a screen-shaped levelling plate (27) over said conveyor terminal, a reciprocating feeder under said levelling plate and away from said terminal which is slightly tilted and moves horizontally, a hammering unit (19) over said reciprocating feeder and spaced apart from said levelling plate, at The upper part of said feeder which moves vertically in association with the reciprocating motion of said feeder, an impeller (20) disposed for receiving the hammered material of said feeder for separation, a wallplate (51) at the upper part of said impeller (20) with receiving plates (52, 52'') which are inside said wallplate, and slanting plates which are at the lower part of the impeller, and also a screening blower (21) in said impeller; and, h. carrier conveyor means on the output side of said impeller by which screened core material (59) and insulating material (60) are respectively collected and carried away.

Claim 2

A device for separating wire from its insulating material, comprising in combination: a. carrying means (2) for carrying a bundle (3) of wires in a flow direction to a cutter (1); b. a cutting mechanism in the cutter (1) for cutting the bundle (3) of wires to a desired length; c. an oscillating feeder (4) adjacent said cutter (1) which supplies the wire material (3'') cut to desired lengths; d. a rapid cooling unit (6) with a circulating pipe, fed by said feeder (4), including a rotatable screen-shape levelling unit (5) which levels passing material to a uniform thickness; e. an elongated insulating box (7) with an endless net-like conveyor (8) carrying the cut wire material (3'') within said box to a terminal; f. an injection nozzle (12) at the rear end of said box atomizing a low-temperature coolant flowing therein from a storage tank (9) and spraying it onto the wire material (3'') near the rear end of said insulating box (7), including a valve (1) and a connecting pipe (11) said rapid cooling unit (6) extending from the forward to the rear end of said insulating box (7) and circulates cooling gas to precool the wire material (3''); g. a separating device (17) at said conveyor terminal in which the wire material (3'') cooled by said rapid cooling unit (6) is separated into insulating material (60) and core material (59) such as copper wire and which includes a screen-shaped levelling plate (27) over said conveyor terminal, a reciprocating feeder under said levelling plate and away from said terminal which is slightly tilted and moves horizontally, a hammering unit (19) over said reciprocating feeder and spaced apart from said levelling plate, at The upper part of said feeder which moves vertically in association with the reciprocating motion of said feeder, an impeller (20) disposed for receiving the hammered material of said feeder for separation, a wallplate (51) at the upper part of said impeller (20) with receiving plates (52, 52'') which are inside said wallplate, and slanting plates which are at the lower part of the impeller, and also a screening blower (21) in said impeller; and, h. carrier conveyor means on the output side of said impeller by which screened core material (59) and insulating material (60) are respectively collected and carried away.
