Vorrichtung für das Recycling von Folien aus Polyethylen niedriger Dichte (PE-LD)Device for recycling low density polyethylene (PE-LD) films
BeschreibungDescription
Die Erfindung bezieht sich auf eine Vorrichtung für das Recycling von Folien aus Polyethylen niedriger Dichte (PE-LD).The invention relates to a device for recycling films made of low density polyethylene (PE-LD).
Zu dieser Art gehörende Vorrichtungen sind bereits aus dem Deutschen Gebrauchsmuster G 90 17 858.0 bekannt.
Die dort beschriebene und sicher auch funktionsfähige Anlage soll allerdings geeignet sein für die Verwendung beim Recycling
von verschiedenartigsten Kunststoffen, wie Polyethylen, Polypropylen, Polystyrol, Polyvinylchlorid und Styropor.
Aufgrund der äußerst unterschiedlichen Eigenschaften dieser einzelnen Kunststoffe kann eine solche Vorrichtung im Betrieb
für jeden spezifischen Kunststoff nur einen Kompromiß darstellen.Devices of this type are already known from the German utility model G 90 17 858.0.
However, the system described there, which is certainly functional, is intended to be suitable for use in recycling a wide variety of plastics, such as polyethylene, polypropylene, polystyrene, polyvinyl chloride and Styrofoam. Due to the extremely different properties of these individual plastics, such a device can only represent a compromise in operation for each specific plastic.
Aufgrund der zu erwartenden Mengen an zu recycelnden Kunststoffen aus den Haushalten und aus dem Gewerbe und aufgrund der hohen Anforderungen an die Qualität des Recyclates muß eine solche Vorrichtung optimal für jeden einzelnen spezifischen Kunststoff konzipiert sein.Due to the expected quantities of plastics to be recycled from households and businesses and due to the high demands on the quality of the recyclate, such a device must be optimally designed for each specific plastic.
Die Aufgabe der Erfindung war es deshalb, eine Vorrichtung für das Recycling von Folien aus Polyethylen niedriger Dichte
(PE-LD) zu schaffen, die bezüglich des Einsatzes bei Folien aus PE-LD optimale Arbeits-, Durchsatz- und Qualitätsvoraussetzungen
bietet.The object of the invention was therefore to develop a device for recycling low-density polyethylene films
(PE-LD) which offers optimal working, throughput and quality conditions for use with PE-LD films.
Die Lösung dieser Aufgabe erreicht eine Vorrichtung für das Recycling von Folien aus PE-LD bestehend aus der Kombination der nachfolgenden Elemente, die in der aufgelisteten Reihenfolge angeordnet sind:The solution to this problem is achieved by a device for recycling PE-LD films consisting of a combination of the following elements arranged in the order listed:

Contraption.
In speziellen Fällen können die Gegenstände der Unteransprüche besonders vorteilhaft sein.In special cases, the subject matter of the subclaims may be particularly advantageous.
In der Zeichnung ist die Anordnung einer erfindungsgemäßen Vorrichtung beispielhaft schematisch dargestellt.The arrangement of a device according to the invention is shown schematically as an example in the drawing.
Die in den mehrstufigen Shredder I aufgegebenen Folien kommen aus einer Sortieranlage, in der bereits manuell Folien aussortiert werden, die nicht aus PE-LD bestehen. Weiterhin werden in der Sortieranlage andere Fremdkörper und grobe Verunreinigungen entfernt. Eisenmetalle werden über Magnetabscheider abgetrennt.The films fed into the multi-stage shredder I come from a sorting system in which films that are not made of PE-LD are manually sorted out. Furthermore, other foreign bodies and coarse contaminants are removed in the sorting system. Ferrous metals are separated using magnetic separators.
Dieses so vorsortierte Foliengut wird in dem mehrstufigen Shredder 1 in Folienschnitzel von einer Größe von etwa 1 cm2 bis 10 cm2 zerkleinert.This pre-sorted film material is shredded in the multi-stage shredder 1 into film chips with a size of approximately 1 cm2 to 10 cm2 .
Die Folienschnitzel werden in einem Einrührbehälter 2 mit Rührwerk in Wasser dispergiert und unter definiertem Druck in ein Hydrozyklon 3 gepumpt, in dem bereits Verunreinigungen und Schwerbestandteile abgetrennt werden. Das Wasser aus dem Hydrozyklon 3 wird in einer Siebmaschine 4 gereinigt.The film chips are dispersed in water in a mixing tank 2 with agitator and pumped under defined pressure into a hydrocyclone 3, in which impurities and heavy components are separated. The water from the hydrocyclone 3 is cleaned in a screening machine 4.
In einem ersten Friktionsabscheider 5 werden die Folienschnitzel vom Schmutzwasser und von Verunreinigungen getrennt.In a first friction separator 5, the film chips are separated from the dirty water and impurities.
Die vorgetrennten Folienschnitzel werden in zwei nacheinander angeordneten Turbowäschern 6 und 7 mit hoher Wassergeschwindigkeit gewaschen und gelangen dann in einen mechanischen Trockner 8, in dem sie von dem Wasser und von Kleinstverunreinigungen getrennt werden.The pre-separated film chips are washed in two turbo washers 6 and 7 arranged one after the other at high water speed and then enter a mechanical dryer 8, where they are separated from the water and from small contaminants.
Über eine Fördereinrichtung werden diese Folienschnitzel dann in ein Trennbecken 9 gebracht, in dem über Sink-Schweb-Trennung weitere Schwerbestandteile und Bestandteile aus anderen Fremdkunststoffen entfernt werden.These film chips are then transported via a conveyor system to a separation tank 9, in which additional heavy components and components from other foreign plastics are removed via sink-float separation.
Danach gelangen die Folienschnitzel zur ersten Wasserabtrennung in einen zweiten Friktionsabscheider 10 und von dort in zwei parallel geschaltete mechanische Trockner 8a.The film chips then pass into a second friction separator 10 for the first water separation and from there into two mechanical dryers 8a connected in parallel.
Die vorgetrockneten Folienschnitzel werden in einer Mühle 11 in Folienpartikel von einer Größe < 1 cm2 gemahlen und dann in einer thermischen Nachtocknung 12 auf eine Restfeuchte unter 1% getrocknet.The pre-dried film chips are ground in a mill 11 into film particles of a size < 1 cm 2 and then dried in a thermal post-dryer 12 to a residual moisture content of less than 1%.
Danach werden die Folienpartikel in einem Zwischensilo 13 permanent durchmischt und somit homogenisiert sowie gepuffert,
bevor sie in einen Extruder 14 gefördert werden.
Im Extruder 14 werden in einer Entgasungseinrichtung noch einmal Wasserdampf und andere flüchtige Bestandteile entfernt und die
Schmelze dann noch in einer Schmelzesiebeinrichtung von festen Bestandteilen, die größer als die Sieblochgröße sind, z.B.
größer als 150 &mgr;&igr;&eegr;, befreit. Danach wird die Schmelze, z.B. in
einem Heißabschlag oder in einer Stranggranulierung noch regranuliert und anschließend das erzeugte Regranulat in ein
Granulatsilo 15 verbracht.The film particles are then continuously mixed in an intermediate silo 13 and thus homogenized and buffered before they are conveyed into an extruder 14.
In the extruder 14, water vapor and other volatile components are removed again in a degassing device and the melt is then freed from solid components that are larger than the screen hole size, e.g. larger than 150 μm, in a melt screening device. The melt is then regranulated, e.g. in a hot die or in a strand granulation, and the regranulate produced is then transferred to a granulate silo 15.
Das gesamte Wasser, das in der Vorrichtung verwendet wird, wird permanent in einer Wasseraufbereitungsanlage gereinigt und wieder in den Kreislauf zurückgeführt.All the water used in the device is permanently cleaned in a water treatment plant and returned to the cycle.
Die gesamte Vorrichtung ist computergesteuert, -geregelt und überwacht. The entire device is computer controlled, regulated and monitored.
