Description
AT 401 482 BAT 401 482 B
Die Erfindung betrifft ein Verfahren zum Behandeln ölverschmutzter Kunststoff- oder Metallteilen.The invention relates to a method for treating oil-contaminated plastic or metal parts.
Derartige Teile fallen bei Werkstätten, insbesonders KFZ-Werkstätten und bei Tankstellen, aber auch bei metallverarbeitenden Betrieben im Maschinenbau und in der chemischen Industrie laufend in großer Menge an. Diese Teile sind beispielsweise Ölfilter, Luftfilter, Kleingebinde für Öl u.dgl.Such parts are constantly being produced in large quantities in workshops, in particular car workshops and at petrol stations, but also in metalworking companies in mechanical engineering and in the chemical industry. These parts are, for example, oil filters, air filters, small containers for oil and the like.
Aus der EP-A 0 280 753 ist ein Verfahren zur Beseitigung von schadstoffhaltigem Haufwerken (Öltanksedimentschlamm, Venturischlamm, ölverunreinigtes Erdreich, Flugasche) bekannt. Dabei wird das Haufwerk unter Zusatz von Anmachwasser in eine hydraulische Masse übergeführt und ausgehärtet. Dabei wird vor dem Erhärten eine wässerige Dispersion eines filmbildenden Kunststoffes (Acrylester, Styrol- oder Butadien-Copolymerisat) zugesetzt und intensiv in der Masse verteilt. Die ausgehärtete Masse kann deponiert oder in zerkleinerter Form (z.Bsp. als Baustoff) wiederverwendet werden.EP-A 0 280 753 discloses a method for removing polluted piles (oil tank sediment sludge, Venturi sludge, oil-contaminated soil, fly ash). With the addition of mixing water, the pile is converted into a hydraulic mass and hardened. Before hardening, an aqueous dispersion of a film-forming plastic (acrylic ester, styrene or butadiene copolymer) is added and distributed intensively in the mass. The hardened mass can be deposited or reused in shredded form (e.g. as a building material).
Gegenüber diesem vorbekannten Verfahren hat die Erfindung die Behandlung von Metall- bzw. Kunststoffteilen zum Inhalt, die auch mit Anmachwasser und zugesetztem Kunststoff nicht aushärtbar sind.Compared to this previously known method, the invention relates to the treatment of metal or plastic parts which cannot be cured even with mixing water and added plastic.
Die Metall- bzw. Kunststoffteile könnten als Rohstoff wiederverwendet werden, wenn eine möglichst vollständige und zuverlässige Abtrennung des an ihnen haftenden Öles mit vertretbarem technischem und finanziellem Aufwand gelingt.The metal or plastic parts could be reused as a raw material if the oil adhering to them could be separated as completely and reliably as possible with justifiable technical and financial expenditure.
Es ist somit Ziel der Erfindung, ein derartiges Verfahren anzugeben und die Wiederverwendung der gereinigten Teile zu ermöglichen.It is therefore the object of the invention to provide such a method and to enable the cleaned parts to be reused.
Erfindungsgemäß geschieht dies durch ein Verfahren, bei dem die ölbehafteten Kunststoff- oder Metallteile mit einem Ölbindemittel versetzt, anschließend in einem Mahlwerk auf eine Partikelgröße von 40 mm oder kleiner gemahlen und in der Folge in einem Mischer gemahlen werden, sodann in einem Mischer umgewälzt werden, wodurch das Öl im wesentlichen vollständig vom Bindemittel gebunden wird, und daß in der Folge die im wesentlichen vom Öl- und bindemittelfreien Kunststoff- bzw. Blechteile vom ölhältigen Bindemittel getrennt werden.According to the invention, this is done by a method in which the oil-containing plastic or metal parts are mixed with an oil binder, then ground in a grinder to a particle size of 40 mm or smaller and subsequently ground in a mixer, then are circulated in a mixer, whereby essentially all of the oil is bound by the binder, and that as a result the essentially oil and binder-free plastic or sheet metal parts are separated from the oil-containing binder.
Als Bindemittel können alle Stoffe verwendet werden, die die nachfolgenden Verfahrensschritte nicht stören: Kunststoffschäume, wie Polyurethane, Stroh, Papierfasern, bevorzugt aber Sägespäne, da diese in der Folge selbst ein wertvoller Rohstoff sind.All substances that do not interfere with the following process steps can be used as binders: plastic foams, such as polyurethanes, straw, paper fibers, but preferably sawdust, since these are themselves a valuable raw material.
Das Mahlwerk muß in der Lage sein, die anfallenden Teile auf die erforderliche Partikelgröße von maximal 40 mm zu zerkleinern und besteht bevorzugt aus einem Shredder mit zwei Zerkleinerungsstufen. Es können auch mehrere Shredder oder auch andere Mahlwerke, (Hammermühlen, Kugelmühlen) in Serie geschaltet werden. Günstig bei der Verwendung von Shreddern ist, daß diese Vorrichtungen das Mahlgut einer starken Scherbeanspruchung unterwerfen, was für die Verteilung des Ölbindemittels vorteilhaft ist.The grinder must be able to shred the parts to the required particle size of maximum 40 mm and preferably consists of a shredder with two shredding stages. Several shredders or other grinders (hammer mills, ball mills) can also be connected in series. It is favorable when using shredders that these devices subject the regrind to strong shear stress, which is advantageous for the distribution of the oil binder.
Der Mischer kann im einfachsten Fall ein Trommelmischer mit verschiedenen Leitblechen od.dgl. sein, es ist auch möglich, konstruktiv aufwendigere Mischer zu verwenden, dies hängt vom Ausgangsmaterial und dem gewünschten Endresultat ab und ist vom Fachmann in Kenntnis der Erfindung und der Betriebsbedingungen leicht bestimmbar.In the simplest case, the mixer can be a drum mixer with different baffles or the like. be, it is also possible to use more complex mixers, this depends on the starting material and the desired end result and can be easily determined by a person skilled in the art with knowledge of the invention and the operating conditions.
Die Abscheidung der gereinigten Teile von nunmehr ölhältigen Ölbindemitteln erfolgt bei ferromagnetischen Teilen bevorzugt magnetisch durch magnetische Trommel- oder Bandabscheider, bei nichtmagnetischen Partikeln durch Siebe, Sichter Zyklone oder durch Windsichtung.In the case of ferromagnetic parts, the cleaned parts from oil-containing oil binding agents are preferably separated magnetically by means of magnetic drum or belt separators, and in the case of non-magnetic particles by sieves, classifiers, cyclones or by air separation.
Beim Vorliegen eines Partikelgemisches aus magnetischen und unmagnetischen Teilen können beide Abtrennarten in beliebiger Reihenfolge in Serie geschalten sein.If a particle mixture of magnetic and non-magnetic parts is present, both types of separation can be connected in series in any order.
Die Verwendung von Sägemehl oder Sägespänen bringt den unerwarteten Vorteil mit sich, daß diese sich, unabhängig vom Grad ihrer Ölaufnahme, von den Partikeln besser lösen als die anderen Ölbindemittel und daß sie darüberhinaus in großer Menge kostengünstig anfallen und zuätzlich auch nach dem Aufsaugen des Öles nützlich verwendbar sind, beispielsweise durch Verpressen zu brikettartigen, als Brennstoff dienen Blöcken oder Pellets gemäß der deutschen Patentanmeldung 33 08 734.The use of sawdust or sawdust has the unexpected advantage that, regardless of the degree of oil absorption, they separate from the particles better than the other oil binders and that they are also inexpensive in large quantities and are also useful after the oil has been absorbed can be used, for example by pressing into briquette-like blocks or pellets according to German patent application 33 08 734.
Die Erfindung wird anhand der Zeichnung, die aus einer einzigen Figur besteht, näher erläutert.The invention is explained in more detail with reference to the drawing, which consists of a single figure.
Die mit Öl behafteten Kunststoff- und/oder Blechgegenstände 13 werden, üblicherweise nach einer händischen Vorsortierung, mittels eines Förderbandes 1 einem Zerkleinerer 2 zugeführt. Ebenfalls dem Zerkleinerer 2 wird Ölbindemittel 12 aus einem Vorratsbehälter 3 zugeführt.The plastic and / or sheet metal objects 13, which are contaminated with oil, are fed to a shredder 2, usually after manual presorting, by means of a conveyor belt 1. Oil binder 12 is also supplied to the shredder 2 from a storage container 3.
Durch die beim Zerkleinern auftretende Scherwirkung kommt es zu einer ersten, aber bereits innigen Vermischung des Ölbindemittels 12 mit den ölbehafteten Gegenständen 13 während deren Zerkleinerung. Dadurch gelangt ein großer Teil des Öls schon während dieser Stufe von den Gegenständen in das Bindemittel.The shear effect that occurs during comminution results in a first but already intimate mixing of the oil binding agent 12 with the oil-laden objects 13 during their comminution. As a result, a large part of the oil gets into the binder from the objects during this stage.
In der Folge werden die zerkleinerten Gegenstände - nunmehr Partikel 4 genannt - und das bereits teilweise mit Öl versetzte Ölbindemittel 12 in einen Mischer 5, der beispielsweise und bevorzugt ein Trommelmischer ist. Andere Mischertypen können selbstverständlich auch verwendet werden.As a result, the comminuted objects - now called particles 4 - and the oil binder 12 which has already been partially oiled are placed in a mixer 5, which is, for example and preferably, a drum mixer. Other types of mixers can of course also be used.
Vom Mischerausgang gelangen die nunmehr im wesentlichen ölfreien Partikel 4 und das ölhältige Ölbindemittel 12 über eine Transportvorrichtung 6, im einfachsten Fall ein Förderband, zu einer Abtrennein- 2From the mixer outlet, the now essentially oil-free particles 4 and the oil-containing oil binding agent 12 reach a separating device via a transport device 6, in the simplest case a conveyor belt
