Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Trennen verschmutzter Kunststoffprodukte mit unterschiedlichen Erweichungspunkten, die zerkleinert und gereinigt über eine Zwischenlagerung einer weiteren Verarbeitung zugeführt werden.The invention relates to a method and an apparatus for Separate contaminated plastic products with different ones Softening points that are crushed and cleaned over a Interim storage can be sent for further processing.
Derartige Verfahren werden zum Aufbereiten und Wiederverwenden stark verschmutzter Kunststoffprodukte eingesetzt, wie z. B. in der DE-PS 25 25 750 beschrieben ist.Such processes are used for reprocessing and reuse heavily soiled plastic products used such. B. in DE-PS 25 25 750 is described.
Die Trennung von zerkleinerten Kunststoffabfällen mit höheren und niederen spezifischen Gewichten als eine Waschflüssigkeit ist in der DE-PS 28 04 729 beschrieben. Hier erfolgt die Trenn ung in einem Naß-Sink-Verfahren.The separation of shredded plastic waste with higher and lower specific weights than a washing liquid is described in DE-PS 28 04 729. The separation takes place here in a wet-sink process.
Demgegenüber fallen verschmutzte, unterschiedliche Kunststoff produkte an, deren spezifische Gewichte so eng beieinander lie gen, daß eine Naß-Sink-Trennung nach der Zerkleinerung nicht möglich ist. So fallen verschmutzte Kunststoff-Formteile, wie Flaschen, Kästen od. dgl. an, die aus Polyester (PET) und Poly vinylchlorid (PVC) bestehen. Beide Materialien haben nahezu gleiche spez. Gewichte.In contrast, dirty, different plastics fall products whose specific weights were so close together gene that a wet-sink separation after crushing is not is possible. So dirty plastic moldings fall, like Bottles, boxes or the like. Made of polyester (PET) and poly vinyl chloride (PVC) exist. Both materials have almost same spec. Weights.
Zur Trennung derartiger Materialien (wobei auch andere Kombi nationen denkbar sind) wurden diese vor dem Recycling auf För derbänder aufgegeben und dort manuell getrennt. Aufgrund mensch licher Fehler ist auch hier eine 100%ige Trennung nicht mög lich. Um die Fehlerquellen zu verringern, wurde ein Röntgen strahlen-Verfahren eingesetzt. Die Strahlen können Chloride enthaltende Teile erfassen und somit PVC von PET trennen. Ab gesehen von den hohen Kosten und der Strahlengefährdung für das Personal ist auch hier eine 100%ige Trennung nicht möglich. Sind z. B. die Formteile mit Aufkleber versehen, dann können die Strahlen das Kunststoffmaterial nicht erfassen, so daß es wie Materialien ohne Chloridanteile behandelt wird.For the separation of such materials (although other combinations nations are conceivable) these were recycled to För derband abandoned and separated there manually. Because of human 100% separation is not possible here either Lich. To reduce the sources of error, an X-ray was taken radiation process used. The rays can be chlorides Detect contained parts and thus separate PVC from PET. From seen from the high cost and exposure to radiation for here, too, the staff cannot be separated 100%. Are z. B. provide the moldings with stickers, then you can the rays do not capture the plastic material, so that it how materials without chloride are treated.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zu schaffen, womit unterschiedliche Kunststoff produkte absolut sicher voneinander getrennt werden können.The invention has for its object a method and to create a device with which different plastic products can be separated from each other with absolute security.
Diese Aufgabe wird dadurch gelöst, daß trockene Kunststoffteil chen aus der Zwischenlagerung in dünner Schicht auf eine beheiz te, bewegte Unterlage gegeben werden, deren Temperatur so ein gestellt wird, daß die Kunststoffteilchen mit dem niederen Er weichungspunkt an der Oberfläche der Unterlage anhaften, so daß sich die Kunststoffteilchen mit dem höheren Erweichungspunkt frei darüber bewegen und im Bereich einer Neigung der Unterlage nach unten im freien Fall aufgefangen werden, und daß danach die anhaftenden Kunststoffteilchen von der Unterlage abgeschabt werden.This object is achieved in that dry plastic part Chen from the intermediate storage in a thin layer on a heated te, moving pad, the temperature of which is given is placed that the plastic particles with the lower Er Adhere the softening point to the surface of the base so that the plastic particles with the higher softening point move freely over it and in the area of an inclination of the base down to be caught in free fall, and that after that scraped off the adhering plastic particles from the surface will.
Mit diesem Verfahren werden die Kunststoffteilchen mit dem nie deren Erweichungspunkt geringfügig plastifiziert und können folgedessen an der Oberfläche der Unterlage anhaften. Dies be deutet, daß z. B. PVC-Teilchen anhaften und sich somit die PET- Teilchen frei bewegen können. Dabei wird die Temperatur der Unterlage so eingestellt, daß der an sich bekannte Plastifi zierpunkt gerade erreicht wird und demzufolge dieses Material, nach der Abtrennung der anderen Komponente ohne Schwierigkeiten von der Unterlage abgeschabt werden kann.With this process, the plastic particles are never whose softening point is slightly plasticized and can consequently adhere to the surface of the pad. This be indicates that e.g. B. PVC particles stick and thus the PET Particles can move freely. The temperature of the Document set so that the well-known plastifi decorative point is just reached and therefore this material, after separating the other component without difficulty can be scraped off the surface.
Es kann vorkommen, daß PET-Teilchen auf der Unterlage liegen und sich darauf PVC-Teilchen ablegen, die dann gemeinsam mit den PET-Teilchen aufgefangen werden. In einer weiteren Trennstufe können dann die restlichen PVC-Teilchen abgetrennt werden.It can happen that PET particles lie on the base and PVC particles are deposited on it, which then together with the PET particles can be collected. In a further separation stage the remaining PVC particles can then be separated.
Eine bevorzugte Trennung kann mittels rotierender Elemente, wie Trommeln oder einem über Umlenkrollen laufenden Stahlband erfol gen. Diese Elemente können mit einfachsten Mitteln von innen mit Heißluft, Infrarotbestrahlung od. dgl. beheizt werden.A preferred separation can be by means of rotating elements such as Drums or a steel belt running over deflection rollers These elements can be done from the inside with the simplest of means be heated with hot air, infrared radiation or the like.
Die Erfindung ist nicht an das beschriebene Beispiel, Trennung von PET- und PVC-Teilchen, gebunden. So lassen sich auch andere Materialien, wie Polystyrol (PS) oder die Kombination PVC/PS von PET trennen. Auch können Heißkleber (HOT-MELT) von PET ge trennt werden.The invention is not related to the example described, separation of PET and PVC particles. This is how others can be Materials such as polystyrene (PS) or the combination PVC / PS separate from PET. Hot glue (HOT-MELT) from PET can also be used be separated.
Zwei vorteilhafte Ausführungsformen sind in der Zeichnung darge stellt und werden nachfolgend näher beschrieben. Es zeigt:Two advantageous embodiments are shown in the drawing represents and are described in more detail below. It shows:
Fig. 1 eine Vorrichtung aus drei übereinander angeordneten Trommeln, Fig. 1 shows a device of three superposed drums,
Fig. 2 ein über Umlenkrollen laufendes Stahl band. Fig. 2 a running over pulleys steel band.
Fig. 1 zeigt eine drei-stufige Vorrichtung. Selbstverständlich gehört auch eine einstufige Vorrichtung zum Schutzbereich der Erfindung. Fig. 1 shows a three-stage device. Of course, a one-stage device also belongs to the scope of the invention.
Die Trennvorrichtung 1 besteht aus drei Trommeln 2, 3, 4, die je weils auf Wellen 5, 6, 7 gelagert und von Antrieben 8, 9, 10 rotiert werden. Im Inneren der Trommeln 2-4 sind Breitdüsen 11, 12, 13 vorgesehen, die über eine Sammelleitung 17 an Heißluftleitungen 14, 15, 16 angeschlossen sind. Oberhalb der oberen Trommel 2 ist eine Aufgabevorrichtung 18 mit vorgeschaltetem Silo 18 vorgesehen, über die die gemeinsam zerkleinerten, gereinigten und getrockneten unterschiedlichen Kunststoffprodukte auf die Oberfläche der Trommel 2 aufgegeben werden. Die PVC-Teilchen 19 haften infolge ihrer Plastifizierung auf der Oberfläche der Trommel 2 und werden mittels eines Schabers 20 der Abnahmevorrichtung 21 abgeschabt und weiter geleitet. Anstelle des Schabers kann auch eine rotierende Stahlbürste od. dgl. die anhaftenden PVC-Teilchen von der Trommeloberfläche ab bürsten. Die frei fließenden PET-Teilchen 22, gegebenenfalls mit restlichen PVC-Teilchen 19 fallen in die Auffangvorrichtung 23. Die Teile 20 und 23 liegen unterhalb der Achse "A". Von der Auf fangvorrichtung 23 gelangen die Teilchen in eine Aufgabevorricht ung 24 für die Trommel 3, wobei wiederum eine Trennung der Teil chen 19a und 22a mittels Schaber 25 der Abnahmevorrichtung 26 und der Auffangvorrichtung 27 erfolgt. Ein dritter Trennvorgang wird mittels der Trommel 4, dem Schaber 29 der Abnahmevorrichtung 30 und der Auffangvorrichtung 31 durchgeführt. Aus der Leitung 32 können reine PET-Teilchen entnommen werden.The separating device 1 consists of three drums 2 , 3 , 4 , each of which is supported on shafts 5 , 6 , 7 and rotated by drives 8 , 9 , 10 . In the interior of the drums 2-4 , wide nozzles 11 , 12 , 13 are provided, which are connected to hot air lines 14 , 15 , 16 via a manifold 17 . Above the upper drum 2 there is a feed device 18 with an upstream silo 18 , by means of which the differently comminuted, cleaned and dried different plastic products are fed onto the surface of the drum 2 . The PVC particles 19 adhere due to their plasticization on the surface of the drum 2 and are scraped off by a scraper 20 of the removal device 21 and passed on. Instead of the scraper, a rotating steel brush or the like can brush the adhering PVC particles off the drum surface. The free-flowing PET particles 22 , possibly with remaining PVC particles 19 , fall into the collecting device 23 . Parts 20 and 23 are below axis "A". From the collecting device 23 , the particles enter a feed device 24 for the drum 3 , again separating the parts 19 a and 22 a by means of a scraper 25 of the take-off device 26 and the collecting device 27 . A third separation process is carried out by means of the drum 4 , the scraper 29 of the removal device 30 and the collecting device 31 . Pure PET particles can be removed from line 32 .
Anstelle der drei Trommeln 2-4 kann ein über Umlenkrollen 35, 36 laufendes Stahlband 34 der Trennvorrichtung 33 eingesetzt werden. Die Umlenkrollen 35, 36 sind in Wellen 37, 38 mit Lagern 39, 40 abgestützt. Mittels eines Motors 41 wird das Stahlband 34 mit einer Laufrichtung gemäß Pfeil 42 angetrieben. Im Innern des Stahlbandes 34 ist ein Heißluftkasten 43 vorgesehen, der an eine Heißluftleitung 44 angeschlossen ist. Im oberen Teil des Heißluftkastens 43 sind Luft düsen 45 zum Beheizen des Stahlbandes 34 angeordnet. Im Bereich zwischen den beiden Umlenkrollen 35, 36 befindet sich oberhalb des Stahlbandes 34 eine Aufgabevorrichtung 46 mit vorgeschaltetem Silo 46a , mittels der die zerkleinerten, gereinigten und getrockneten unterschiedlichen Kunststpoffprodukte auf das Stahlband 34 in dünner Schicht aufgegeben werden. Unterhalb der Achse "B" befinden sich einerseits die Auffangvorrichtung 47 für die PET-Teilchen und andererseits die Abnahmevorrichtung 49 mit dem Schaber 50 für die PVC-Teilchen 58. Die gesamte Vorrichtung 33 ist mittels Stützen 63, 64 auf zwei Unwucht-Vibratoren 51, 52 abgestützt. Diese sind so eingestellt, daß die frei fließenden PET-Teilchen 48 eine Transport richtung gemäß Pfeil 63 erhalten. Vibration und Lage der Einrichtung 33 können derart eingestellt werden, daß sich die PET-Teilchen mittels vorbestimmter Wurfparabel über das Stahlband bewegen. Somit wird erreicht, daß alle PVC-Teilchen 58 Kontakt mit dem heißen Stahlband 34 bekommen und dort anhaften. Folglich kann die Trenn vorrichtung 33 so gefahren werden, daß aus der Leitung 55 nur PET- Teilchen entnommen werden. Die 100%ige Trennung von PET- und PVC-Teichen (oder anderen Komponenten) wird u. a. infolge der verschiedenen Bewegungsrichtungen beider Materialien auf dem Stahlband 34 erreicht.Instead of the three drums 2-4 , a steel belt 34 of the separating device 33 running over deflection rollers 35 , 36 can be used. The deflection rollers 35 , 36 are supported in shafts 37 , 38 with bearings 39 , 40 . The steel belt 34 is driven by a motor 41 with a running direction according to arrow 42 . A hot air box 43 is provided in the interior of the steel strip 34 and is connected to a hot air line 44 . In the upper part of the hot air box 43 air nozzles 45 are arranged for heating the steel strip 34 . In the area between the two deflection rollers 35 , 36 there is a feed device 46 above the steel belt 34 with an upstream silo 46 a, by means of which the shredded, cleaned and dried different plastic products are applied to the steel belt 34 in a thin layer. Below the axis "B" are on the one hand the collecting device 47 for the PET particles and on the other hand the removal device 49 with the scraper 50 for the PVC particles 58 . The entire device 33 is supported on two unbalance vibrators 51 , 52 by means of supports 63 , 64 . These are set so that the free-flowing PET particles 48 receive a transport direction according to arrow 63 . Vibration and position of the device 33 can be adjusted in such a way that the PET particles move over the steel belt by means of a predetermined parabola. This ensures that all PVC particles 58 come into contact with the hot steel strip 34 and adhere there. Consequently, the separation device 33 can be operated so that only PET particles are removed from the line 55 . The 100% separation of PET and PVC ponds (or other components) is achieved, among other things, due to the different directions of movement of both materials on the steel belt 34 .
