<p>The object of this invention is to provide a device for recovering copper from waste electric lines. This device consists of an electric line intake hopper (2), an extrusion cutting unit (3) cutting the waste electric lines to form waste line bundles, and a feeding unit (4) feeding the line bundles from the cutting unit (3) to a sintering furnace (5) where the bundles are sintered. The sintered line bundles are first crushed by a roll breaker (6), thus being divided into copper wires and sheaths. The copper wires are processed by a chain scraper (7) removing remnant sheaths from the wires. A rotary cleaner (8) removes dust from the copper wires fed from the roll breaker. A magnetic separator (9) removes undesired metal components from the copper wires. The device also has a heat exchanger (10), a desulphurizing/deodorizing unit (11) and a dust collector (12).</p> |
