Description
Verfahren zur Entfernung von Isolierungen elektrischer Leitungen. Um das Kupfer isolierter Leitungsdrähte wiederzugewinnen, brannte man bisher die Isolierungen ab, wobei nach Entfernung der Asche die Drähte metallisch oder nur schwach oxydiert zurückblieben.Process for removing insulation from electrical lines. In order to reclaim the copper from insulated wires, they used to burn the Insulations from, whereby after removal of the ashes the wires metallic or only remained weakly oxidized.
Dieses Verfahren ist aber nicht geeignet, isolierte Drähte aus leicht schmelzbaren und leicht verbrennbaren Metallen wie Aluminium und Zink restlos wiederzugewinnen. Dünnere Zinkdrähte z. B. werden auf diese Weise völlig zerstört und verbrannt, so daß nur eine sehr geringwertige Asche übrigbleibt.However, this method is not suitable for making insulated wires easily to completely recover fusible and easily combustible metals such as aluminum and zinc. Thinner zinc wires e.g. B. are completely destroyed and burned in this way, so that only a very poor ashes remain.
Das vorliegende Verfahren besteht nun darin, daß die isolierten Drähte zunächst unter Ausschluß der Luft, also in einer Atmosphäre indifferenter Gase, oder im Vakuum so weit erhitzt werden, daß sämtliche flüchtigen Bestandteile der Isolierungen fortgeführt werden. "Diese kann man dann in Kondensationskammern auffangen und weiter verwerten. Alsdann kann man entweder die Drähte durch leichtes Abklopfen von der nunmehr verkohlten Isolierung befreien, um sie dann in besonderen Behältern einzuschmelzen, oder man kann die Drähte mit der- verkohlten Isolierung gleich weiter erhitzen bis zum Zusammenschmelzen des Metalles, das man nötigenfalls durch Bewegung des Gefäßes, z. B. durch Rotation, erleichtern kann, wobei der Abschluß gegen die Luft aufrecht erhalten werden kann.The present method is now that the insulated wires initially with the exclusion of air, i.e. in an atmosphere of inert gases, or heated in a vacuum to such an extent that all volatile constituents of the Isolations are continued. "These can then be collected in condensation chambers and recycle. Then you can either tap the wires gently Remove the now charred insulation and place it in special containers melted down, or you can continue the wires with the charred insulation heat until the metal melts, if necessary by moving it of the vessel, e.g. B. by rotation, can facilitate, the conclusion against the Air can be maintained.
lach diesem Verfahren gelingt es z: B., Zinkdrähte mit 1,5 mm Querschnitt ohne jede Oxydation des Drahtes völlig von der Isolation zu befreien, so daß das hochwertige Zink, aus dem diese Drähte bestehen, allein durch Einschmelzen zu 73 bis 95 Prozent wiedergewonnen werden kann, wobei der Fehlbetrag als hochwertige Krätze z. B. für Zinkweißfabriken weiter verwendbar ist. Die Wiederverwendbarkeit der flüchtigen Isolierungsbestandteile ist bereits er«#ähnt. Auch die festen, kohlehaltigen Rückstände der Isolierung sind z. B. für Feuerungszwecke weiter zu verwenden.According to this process, it is possible, for example, to completely remove the insulation from zinc wires with a cross-section of 1.5 mm without any oxidation of the wire, so that 73 to 95 percent of the high-quality zinc from which these wires are made can be recovered by melting down can be, with the shortfall as high quality scabies z. B. can be used for zinc white factories. The reusability of the volatile insulation components has already been mentioned. The solid, carbonaceous residues of the insulation are z. B. to continue to use for firing purposes.
Dieses Verfahren ist auch für Kupferdrähte anwendbar zur Entfernung der Kriegsisolierung und sofortigen Weiterverwendung des Kupferdrahtes für eine Neuisolation. Denn während bei der Zerstörung der Isolation an der Luft der Kupferdraht durchgeglüht und weich wird, so daß er für elektrotechnische Zwecke nicht wieder verwendet «#e: den darf, wird nach vorliegendem Verfahren die Isolation bei so niedrigen Temperaturen zerstört, daß die physikalischen Eigenschaften des Kupferdrahtes unverändert bleiben.This procedure is also applicable to copper wires for removal the war isolation and immediate re-use of the copper wire for one Re-isolation. Because while in the destruction of the insulation in the air the copper wire is fully annealed and soft, so that it is not used again for electrical purposes used «#e: the may, according to the present method, the insulation at such low Temperatures destroyed that the physical properties of the copper wire unchanged stay.
