Abstract
Verfahren zum Herauslösen von Verstärkungslagen aus Metalldraht aus Reifen mittels Widerstandserwärmung, bei der ein elektrischer Strom durch die Metalldrähte geleitet wird, der zu einer thermooxidierenden Zerstörung drahtnaher Gummischichten und/oder zur Bildung von flüssigem Oligomer aus drahtnahen Gummischichten führt, dadurch gekennzeichnet, dass die Stromdurchleitung durch die Metalldrähte während des beiderseitigen Auf- oder Einschneidens des Reifens entlang seines Umfanges durch im Außenbereich der Verstärkungslage rotierende Messerscheiben vorgenommen wird, wobei an den Messerscheiben ein elektrischer Strom anliegt und die Messerscheiben beim Schneiden eine Metallkontaktierung bewirken.Method for removing reinforcement layers from metal wire from tires by means of resistance heating, in which an electrical current is passed through the metal wires, which leads to a thermo-oxidizing destruction of wire-near rubber layers and / or to the formation of liquid oligomer from wire-close rubber layers, characterized in that the current is passed through the metal wires are made along the circumference of the tire during the cutting or cutting in on both sides by rotating knife disks in the outer region of the reinforcement layer, an electrical current being applied to the knife disks and the knife disks effecting metal contact during cutting.
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herauslösen der Metalldrähte aus Verstärkungslagen (Breaker) von Reifen bei deren Entsorgung und Recycling.The invention relates to a method and a device for removing the metal wires from reinforcement layers (breakers) of tires during their disposal and recycling.
Derartige Lösungen sind bekannt. So wird in der
Auch die in der
Der Nachteil dieser Lösung besteht im hohen Energieverbrauch und in der mehrstufigen Arbeitsweise.The disadvantage of this solution is the high energy consumption and the multi-stage operation.
Weiter ist es aus der
Für die Widerstandserwärmung werden vorgeschlagen:
- - ein diagonales Durchschneiden des Reifens oder
- - das radiale Einschlagen eines Kammes in den Reifen,
- - cutting the tire diagonally or
- - the radial driving of a comb into the tire,
Diese Maßnahmen finden unabhängig zum eigentlichen Erwärmen statt und sind mit einem zusätzlichen maschinentechnischen Aufwand verbunden.These measures take place independently of the actual heating and are associated with additional mechanical engineering effort.
Aufgabe der Erfindung ist es, das Herauslösen der Verstärkungslagen aus Metalldraht aus dem Reifen effektiv und energieeffizienter vorzunehmen und damit das Verfahren gemäß
Gelöst wird diese Aufgabe mit den Merkmalen der Ansprüche 1 und 3, vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved with the features of
Das erfindungsgemäße Verfahren zum Herauslösen von Verstärkungslagen aus Metalldraht aus Reifen mittels Widerstandserwärmung, bei der ein elektrischer Strom durch die Metalldrähte geleitet wird, der zu einer thermooxidierenden Zerstörung drahtnaher Gummischichten und/oder zur Bildung von flüssigem Oligomer aus drahtnahen Gummischichten führt, sieht vor, dass die Stromdurchleitung durch die Metalldrähte während des beiderseitigen Auf- oder Einschneidens des Reifens entlang seines Umfanges durch im Außenbereich der Verstärkungslage rotierende Messerscheiben vorgenommen wird, wobei an den Messerscheiben ein elektrischer Strom anliegt und die Messerscheiben beim Schneiden eine Metallkontaktierung bewirken.The method according to the invention for removing reinforcement layers from metal wire from tires by means of resistance heating, in which an electric current is passed through the metal wires, which leads to a thermo-oxidizing destruction of wire-near rubber layers and / or to the formation of liquid oligomer from wire-close rubber layers, provides that Current is passed through the metal wires while the tire is cut or cut on both sides along its circumference by knife disks rotating in the outer region of the reinforcement layer, an electrical current being present on the knife disks and the knife disks effecting metal contact during cutting.
Das Aufschneiden der Reifen erfolgt bevorzugt in parallelen Schnitten, wobei die Drehachsen der Messerscheiben miteinander fluchten.The tires are preferably cut open in parallel cuts, the axes of rotation of the cutter disks being aligned with one another.
Das Herauslösen der Verstärkungslagen wird bevorzugt in einem gehausten Raum mit Gasabsaugung für das Spaltgas vorgenommen, um gesundheitliche Belastungen für die Bediener auszuschließen.The reinforcement layers are preferably removed in a housed room with gas extraction for the cracked gas in order to exclude health risks for the operator.
Eine erfindungsgemäße Vorrichtung ist in den Zeichnungen dargestellt und soll zur Erläuterung des Verfahrens dienen.A device according to the invention is shown in the drawings and is intended to explain the method.
