In einem Rührtank zum Rühren einer Aufschlämmung von einem sinterfähigen Staubmaterial wird der Abfalltoner zugeführt und die Aufschlämmung des Staubes, zu dem der Resttoner hinzugefügt wurde, wird zu einem Mischstaub dehydriert. Dieser Mischstaub wird anscshließend gesintert. Dieses sinterfähige Material, in dem Abfalltoner von dem Sintern fusioniert ist, kann Eisenpulver sein und so als Erz verwendet werden. Die Harzkomponenten in dem Abfalltoner brennen beim Verhütten des Erzes und so kann der Resttoner als Ersatz für Koks verwendet werden. Das Verarbeitungsverfahren ist gekennzeichnet durch Mischen des Abfalltoner mit dem Sintermaterial und durch das Sintern dieses Gemisches, wobei einer Staubaufschlämmung aus sinterfähigem Material der Abfalltoner zugegeben und anschließend einer Entwässerung unterzogen wird. Die Menge des Abfalltoner kann mehr als 20 Gew.% in dem sinterfähigen Staub betragen.In a stirring tank for stirring a slurry of a sinterable dust material, the waste toner is supplied, and the slurry of the dust to which the residual toner has been added is dehydrated to a mixed dust. This mixed dust is sintered and then sintered. This sinterable material in which waste toner is fused by the sintering may be iron powder and thus used as ore. The resin components in the waste toner burn when smelting the ore and so the residual toner can be used as a substitute for coke. The processing method is characterized by mixing the waste toner with the sintered material and sintering this mixture, adding the waste toner to a dust slurry of sinterable material, followed by dewatering. The amount of waste toner may be more than 20% by weight in the sinterable dust.

Eine Vorrichtung zur thermischen Behandlung von Stäuben in geschlossenen Behältern, insbesondere zur Agglomeration von Resttoner in Tonerkartuschen mittels Heißluft in einem Drehrohrofen wird in der noch nicht veröffentlichten
Alle aus dem Stand der Technik bekannten Verfahren zum Recyceln von Tonerkartuschen oder -patronen mit vorheriger Entfernung von Tonerresten sind sehr aufwendig und mit einem sehr hohen technischen Aufwand, wie Absaugung des Toners mit ionisierter Luft, Aufbau eines doppelten Wasservorhanges oder Auswaschen des Toner aus den Kunststoffmaterial mit hohem Aufwand der Reinigung und der Rückführung des Wassers in den Zerkleinerungskreislauf, verbunden. Des Weiteren besteht beim Absaugen des Toners aus den Kartuschen und der Vermahlung der Kunststoffe mit noch vorhandenen Resten an Toner eine erhebliche Explosionsgefahr. Der abgesaugte Resttoner wird in Gemischen von Erzen zur Verhüttung der Erze sowie in der Beigabe zu Kunststoffformmassen mit anschließender Verarbeitung zu Kunststoffformteilen, zu Asphaltmischungen oder als Zuschlagstoff zum Zement mit seinen weiteren Zuschlagstoffen verwendet. Bei diesen Verfahren wird der Abfalltoner mit seiner wertvollen Zusammensetzung entweder verbrannt oder zu Zwecken eingesetzt, die nur die Beseitigung des Abfalltoners in Mischungen zum Inhalt haben. Dabei werden teure Inhaltstoffe des Toners, wie Kunstharz, Pigmenten, elektrisierbaren Metalloxiden und Hilfsstoffen vernichtet.All known from the prior art method for recycling toner cartridges or cartridges with prior removal of toner residues are very expensive and with a very high technical effort, such as extraction of the toner with ionized air, building a double water curtain or washing out the toner from the plastic material with a great deal of cleaning and the return of the water in the crushing circuit, connected. Furthermore, there is a significant risk of explosion when sucking the toner from the cartridges and the grinding of the plastics with remaining residues of toner. The extracted residual toner is used in mixtures of ores for the smelting of the ores and in the addition to plastic molding compounds with subsequent processing into plastic moldings, to asphalt mixtures or as an additive to the cement with its other additives. In these processes, the waste toner, with its valuable composition, is either incinerated or used for purposes involving only the disposal of the waste toner in mixtures. In this case, expensive constituents of the toner, such as synthetic resin, pigments, electrifiable metal oxides and auxiliary substances are destroyed.
Aufgabe der Erfindung ist es, ein Verfahren zum Recyceln von Tonerkartuschen oder -patronen schaffen, bei dem das recycelte Kunststoffmaterial frei von Toner ist und so ohne weitere Bearbeitungsschritte der Regranulierung des Kunststoffmaterials zugeführt werden und der Resttoner getrennt von dem Kunststoffrecycel-material weiter verarbeitet werden kann.The object of the invention is to provide a method for recycling toner cartridges or cartridges, wherein the recycled plastic material is free of toner and are supplied to the regranulation of the plastic material without further processing steps and the residual toner can be further processed separately from the plastic recycling material ,
Die Aufgabe der Erfindung wird durch eine Verfahren zum Recyceln von Tonerkartuschen oder -patronen gelöst bei, dem die Tonerkartusche oder -patrone einer Wärmebehandlung unterzogen, nach der Wärmebehandlung die Tonerkartusche oder -patrone geschreddert, das geschredderte Kunststoffrecycelmaterial vom Toner getrennt und anschließend das Kunststoffrecycelmaterial einer Kunststoffgranulierung zugeführt wird und der Toner in einem Lösungsmittel aus einer Mischung aus Ketonen, Ester, Alkoholen und andere Kohlenwasserstoffen oder einzelnen Bestandteilen davon gelöst wird. Bei der Wärmebehandlung wird die Tonerkartusche oder -patrone auf eine Temperatur zwischen 120° bis 160°C für 2–15 min in einem Drehrohrofen erhitzt. Das Lösungsmittel besteht insbesondere aus max. 20 Gew.% an Alkoholen, 30–50% an Ester-Ketonen, 20–40% an Aromaten, 10–20% an Aliphaten und weist einen Methanolgehalt von max. 2,5%, einem Wassergehalt von max. 2% und einem Mineralölgehalt von max. 50% auf und wird. Das geschredderte Kunststoffrecycelmaterial wird nach der Trennung vom Resttoner einer Kunststoffgranulierung zugeführt und zu Regranulat verarbeitet. Das Regranulat kann dann in Kunststoffverarbeitungsprozessen, wie Spitzgießen weiter verarbeitet werden. Der im Lösungsmittel aufgelöste Toner weist eine flüssige bis pastöse Konsistenz auf und kann als rissfester und sehr biegsamer Anstrichstoff oder Konservierungsmittel eingesetzt werden. Dieser Anstrichstoff ist als Korrosionsschutzmittel auch gegen aggressive Medien und Schadinsekten, wie den Schiffsbohrwurm (Teredo navalis) oder Termiten geeignet. Mit diesem Verfahren werden die wertvollen Rohstoffe aus Kunststoffrecycelmaterial und des Rest- oder Abfalltoners einer Verwertung zugeführt. Die Erfindung wird nun näher an einem Beispiel erläutert. Die Tonerkartusche mit einem Restgehalt an Toner wird in einem Drehrohrofen mittels Heißluft auf eine Temperatur 160°C für einen Zeitraum von 4 min erhitzt. Durch diese Temperatur agglomeriert der Toner innerhalb der Tonerkartusche und so können bei dem weiterführenden Verfahren keine explosiven Stäube entstehen. Die Tonerkartusche wird dem Drehrohrofen entnommen und einem Schredder zugeführt, in dem die Kunststoffkartusche oder -patronen mit dem agglomerierten Toner geschreddert wird. Nach dem Schreddern werden das Kunststoffrecycelmaterial und der auch geschredderte, agglomerierte Toner durch geeignet Verfahren, wie Windsichten von einander getrennt, wobei das Kunststoffrecycelmaterial weiteren Bearbeitungsschritten zur Herstellung von Regranulat zugeführt werden kann und der Resttoner in einem Lösungsmittel bestehend aus max. 20 Gew.% an Alkoholen, 30–50% an Ester-Ketonen, 20–40% an Aromaten, 10–20% an Aliphaten gelöst wird, wobei das Lösungsmittel einen Methanolgehalt von max. 2,5%, einem Wassergehalt von max. 2% und einem Mineralölgehalt von max. 50% aufweist. Diese Lösung weist dabei je nach Mischungsverhältnis eine flüssige bis pastöse Konsistenz auf und kann so als Anstrich- oder Isolierstoff, auch als Isolierstoff gegen Wasser an Bauwerksgründungen, eingesetzt werden.The object of the invention is achieved by a method of recycling toner cartridges in which the toner cartridge or cartridge is subjected to a heat treatment, the toner cartridge or cartridge shredded after the heat treatment, the shredded plastic recyclate separated from the toner, and then the plastic recyclate of a plastic granulation and the toner is dissolved in a solvent of a mixture of ketones, esters, alcohols and other hydrocarbons or individual components thereof. In the heat treatment, the toner cartridge or cartridge is heated to a temperature between 120 ° to 160 ° C for 2-15 minutes in a rotary kiln. The solvent consists in particular of max. 20% by weight of alcohols, 30-50% of ester ketones, 20-40% of aromatics, 10-20% of aliphatics and has a methanol content of max. 2.5%, a water content of max. 2% and a mineral oil content of max. 50% on and will. The shredded Kunststoffrecycelmaterial is supplied after separation from the residual toner of a plastic granulation and processed into regranulate. The regranulate can then be further processed in plastic processing processes, such as injection molding. The solvent dissolved in the solvent has a liquid to pasty consistency and can be used as a crack-resistant and very flexible paint or preservative. This paint is also suitable as a corrosion inhibitor against aggressive media and noxious insects, such as the marine drillworm (Teredo navalis) or termites. With this method, the valuable raw materials made of plastic recyclable material and the residual or waste toner are recycled. The invention will now be explained in more detail by way of example. The toner cartridge with a residual toner content is heated in a rotary kiln by means of hot air to a temperature of 160 ° C for a period of 4 min. As a result of this temperature, the toner agglomerates within the toner cartridge and thus no explosive dusts can arise in the continuing process. The toner cartridge is removed from the rotary kiln and fed to a shredder where the plastic cartridge or cartridges are shredded with the agglomerated toner. After shredding For example, the plastic recycling material and the shredded, agglomerated toner are separated from each other by suitable methods, such as air classification, wherein the plastic recycling material can be fed to further processing steps to produce regranulate and the residual toner in a solvent consisting of max. 20% by weight of alcohols, 30-50% of ester ketones, 20-40% of aromatics, 10-20% of aliphatics is dissolved, wherein the solvent has a methanol content of max. 2.5%, a water content of max. 2% and a mineral oil content of max. 50%. Depending on the mixing ratio, this solution has a liquid to pasty consistency and can thus be used as a paint or insulating material, as well as an insulating material against water at building foundations.
