Description
Vorrichtung zum Aufbereiten von Kraftfahrzeucr-ShredderreststoffenDevice for processing vehicle shredder residues
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.
Zur Verschrottung vorgesehene Kraftfahrzeuge werden nach dem Entfernen der Batterie sowie des in den Kraftfahrzeugen verbliebenen Öls üblicherweise in Shredderanlagen zerkleinert und die eisenhaltigen Bestandteile werden mittels Magneten aus dem Shreddergut aussortiert und wieder verwertet. Die verbleibenden Shredderreststoffe, insbesondere Kunststoffe, Polsterungen, Gummi und Nichteisen-Metalle, werden im allgemeinen nicht verwertet, sondern unsortiert auf Mülldeponien endgelagert. Hierbei ergeben sich die Probleme einer umständlichen Handhabung und eines relativ großen Raumbedarfs auf der Mülldeponie. Weiterhin erfolgt auf der Deponie durch Sickerwasser ein Auswaschen von Schadstoffen aus diesen Shredderrest-Motor vehicles intended for scrapping are usually shredded in shredders after the battery and the oil remaining in the vehicle have been removed, and the iron-containing components are sorted out of the shredded material using magnets and recycled. The remaining shredder residues, in particular plastics, upholstery, rubber and non-ferrous metals, are generally not recycled but are disposed of unsorted in landfills. This results in the problems of cumbersome handling and a relatively large space requirement in the landfill. Furthermore, pollutants are washed out of these shredder residues by seepage water in the landfill.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Aufbereiten von Kraftfahrzeug-Shredderreststoffen anzugeben, durch die eine wirtschaftlichere Entsorgung der Shredderreststoffe erfolgen kann.It is therefore the object of the present invention to provide a device for processing motor vehicle shredder residues, by means of which the shredder residues can be disposed of more economically.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Extruderpresse zum Verpressen der Shredderreststoffe in kompakte Preßlinge.This object is achieved according to the invention by an extruder press for pressing the shredder residues into compact pressed parts.
Mit einer Extruderpresse lassen sich sehr hohe Drücke erzielen, wobei gleichzeitig eine starke Temperaturerhöhung des gepreßten Materials stattfindet. Hierdurch erweichen insbesondere die Kunststoffe, die in dem verpreßten Material als Bindemittel dienen, so daß ein kompakter Preßling erhalten werden kann.Very high pressures can be achieved with an extruder press, while at the same time the temperature of the pressed material increases significantly. This softens the plastics that serve as binding agents in the pressed material, so that a compact pressed part can be obtained.
Besonders vorteilhaft ist die Verwendung eines Doppelschneckenextruders, in welchem noch höhere Drücke erzielt werden als in einem Exnschneckenextruder und in welchem die Stoffe noch stärker miteinander vermengt werden.It is particularly advantageous to use a twin-screw extruder, in which even higher pressures are achieved than in a single-screw extruder and in which the materials are mixed together even more thoroughly.
Durch das Verpressen im Doppelschneckenextruder wird 0 eine Verdichtung von 2 : 1 bis 3 : 1 gegenüber den unverpreßten Shredderreststoffen erreicht. Dementsprechend verringert sich auch der Platzbedarf beim Transport und auf der Mülldeponie.By pressing in the twin-screw extruder, a compression ratio of 2:1 to 3:1 is achieved compared to the unpressed shredder residue. Accordingly, the space required during transport and at the landfill is reduced.
Im verpreßten Zustand wird das Auswaschen von Schadstoffen aus den Shredderreststoffen erheblich erschwert. Darüber hinaus besteht die Möglichkeit der Versiegelung der Preßlinge, wodurch die Schadstoffabgabe noch weiter gesenkt wird, so daß Eluatwerte (CSB) von weniger als 20 erreicht werden. Diese Preßlinge können bedenkenlos auf einer Hausmülldeponie endgelagert werden.When compressed, it is much more difficult to wash out pollutants from the shredder residue. In addition, it is possible to seal the pressed pieces, which further reduces the release of pollutants, so that eluate values (COD) of less than 20 are achieved. These pressed pieces can be safely disposed of in a household waste landfill.
Schließlich sind die Preßlinge beispielsweise in Form von Briketts oder Pellets wesentlich leichter handhabbar als die ungepreßten Shredderreststoffe. Dies ist insbesondere dann von Bedeutung, wenn diese Reststoffe noch verwertet werden, beispielsweise zur Energiegewinnung in einem Vergaser.Finally, the pressed products, for example in the form of briquettes or pellets, are much easier to handle than the unpressed shredder residues. This is particularly important if these residues are still to be recycled, for example to generate energy in a gasifier.
