Description

Die Erfindung betrifft eine Vorrichtung zum Trennen einer Materialmischung gemäß des Oberbegriffes des Anspruches 1.The invention relates to a device for separating a material mixture according to the preamble of claim 1.

Eine derartige Vorrichtung ist in der nicht vorveröffentlichten DE-OS 41 25 236 beschrieben. Bei dieser Vorrichtung wird die zu trennende Materialmischung gegen eine einstellbare Prallplatte geschleudert. Von dieser feststehenden Prallplatte prallen die Materialien in Abhängigkeit ihrer Festigkeit unterschiedlich stark ab, so daß es zur Trennung des ursprünglichen Materials in zumindest zwei getrennte Teilströme kommt. Diese beiden getrennten Teilströme fallen dann in einen etwa horizontal ausgerichteten Luftstrom. Hierdurch erfolgt eine noch weitere räumliche Trennung der Teilströme von Material, bevor dieses in einer dritten Phase auf eine bewegte, geneigte Fläche fällt. Der Luftstrom befindet sich in einem größerem Abstand zu der geneigten Fläche. Aufgrund der relativ hohen Bewegungsgeschwindigkeit mit der die Materialien von der Prallplatte abprallen und durch den Luftstrom fallen, ergibt sich eine sehr geringe Verweildauer im Luftstrom. Hieraus ergibt sich eine unzureichende Trennschärfe, trotz der Auffächerung des Materialstromes durch das vorhergehende Schleudern gegen die feststehende Prallplatte.Such a device is described in the unpublished DE-OS 41 25 236. In this device, the material mixture to be separated is thrown against an adjustable baffle plate. Depending on their strength, the materials bounce off this fixed baffle plate to different extents, so that the original material is separated into at least two separate partial streams. These two separate partial flows then fall into an approximately horizontally oriented air flow. This results in a further spatial separation of the partial flows of material before it falls on a moving, inclined surface in a third phase. The air flow is at a greater distance from the inclined surface. Due to the relatively high movement speed with which the materials bounce off the baffle plate and fall through the air flow, there is a very short dwell time in the air flow. This results in inadequate selectivity, despite the fanning out of the material flow due to the previous spinning against the fixed baffle plate.

Eine weitere Vorrichtung ist in der DE-PS 2837037 beschrieben. Diese Vorrichtung weist eine Zuführvorrichtung zum Zuführen einer Materialmischung aus Materialien mit unterschiedlichem spezifischen Gewicht zu einer rotierend angetriebenen Sichteinrichtung auf. Diese Sichteinrichtung ist als Sichttrommel ausgebildet. Bei dieser bekannten Vorrichtung wird das zu sortierende Material in das Innere der Sichttrommel aufgegeben. Die Drehachse dieser Sichttrommel weist in Längs- und Zuführrichtung der Zuführvorrichtung. Im Inneren der schräg nach oben angestellten Sichttrommel sollen mit Unterstützung eines Luftstromes die verschiedenen Materialien der Materialmischung voneinander getrennt werden. Derartige Vorrichtungen werden vor allem zur Müll- und Abfallsortierung eingesetzt.Another device is described in DE-PS 2837037. This device has a feed device for feeding a material mixture of materials with different specific weights to a rotatingly driven viewing device. This viewing device is designed as a viewing drum. In this known device, the material to be sorted is fed into the interior of the viewing drum. The axis of rotation of this viewing drum points in the longitudinal and feed directions of the feed device. With the help of an air flow, the various materials of the material mixture are to be separated from each other inside the viewing drum, which is positioned at an angle. Such devices are mainly used for waste and waste sorting.

Diese bekannte Vorrichtung verstopft trotz der vorgeschlagenen Einstellmöglichkeiten, insbesondere wenn die Zusammensetzung der Materialmischung sehr stark schwankt, besonders wenn die Anteile von leichtem zu schwerem spezifischen Gewicht sich ständig ändern. Weiterhin läßt die Sortierqualität zu wünschen übrig.This known device clogs despite the proposed adjustment options, especially when the composition of the material mixture fluctuates very much, especially when the proportions of light to heavy specific weight are constantly changing. Furthermore, the sorting quality leaves something to be desired.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschriebene Vorrichtung in ihrem Aufbau wesentlich zu vereinfachen und gleichzeitig eine störungsunanfällig und verstopfungsfrei arbeitende Vorrichtung zum Trennen einer Materialmischung mit hoher Trennschärfe und hohem Reinheitsgrad zu schaffen.The invention has for its object to simplify the structure of the device described in the introduction and at the same time to create a device for separating a material mixture with high selectivity and high degree of purity which is not susceptible to malfunction and free of clogging.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Infolge dieser Maßnahmen wird eine einfache Vorrichtung zum Trennen einer Materialmischung erhalten, die in überraschender Weise eine äußerst gute Trennung von Materialien unterschiedlichem spezifischen Gewichts gewährleistet. Darüberhinaus arbeitet sie störunanfällig und verstopfungsfrei.This object is achieved by the characterizing features of claim 1. As a result of these measures, a simple device for separating a material mixture is obtained, which surprisingly ensures extremely good separation of materials of different specific weights. In addition, it works unaffected by interference and free of clogging.

Die Verstopfungsfreiheit der Vorrichtung wird durch das unmittelbare Aufgeben der Materialien der Materialmischung von der Zuführeinrichtung auf die Außenseite der Sichteinrichtung sowie den Quereinbau der Drehachse der Sichteinrichtung zur Förderrichtung des Materials gewährleistet. Wobei sich bei ersten Versuchen in überraschender Weise gezeigt hat, daß diese Aufgabeweise des Materials in Verbindung mit einer Luftblaseinrichtung, deren Luftstrom zumindest teilweise gegen die Außenseite der Sichteinrichtung gerichtet ist, zu sehr guten Trennergebnissen führt. Durch die aus der Luftblaseinrichtung austretende Luft werden die leichteren Materialien, wie beispielsweise Papier, Styropor, Pappe, Holzstücke, Folien etc., gegen die Sichteinrichtung gedrückt, so daß die Reibungskraft zwischen der Sichteinrichtung und diesem Material erhöht wird. Somit werden diese Materialien von der angetriebenen Sichteinrichtung mitgerissen, während die schweren Materialien der Materialmischung aufgrund ihrer Gewichtskraft in die andere Richtung abgeschieden werden.The device's freedom from blockage is ensured by the immediate feeding of the materials of the material mixture from the feed device to the outside of the classifying device and the transverse installation of the axis of rotation of the classifying device to the conveying direction of the material. Surprisingly, it has been shown in initial tests that this method of feeding the material in conjunction with an air blowing device, the air flow of which is at least partially directed towards the outside of the viewing device, leads to very good separation results. The air emerging from the air blowing device presses the lighter materials, such as paper, styrofoam, cardboard, pieces of wood, foils etc., against the classifying device, so that the frictional force between the classifying device and this material is increased. These materials are thus entrained by the driven classifying device, while the heavy materials of the material mixture are separated in the other direction due to their weight.

Durch die Sichteinrichtung wird das von der Zuführeinrichtung unmittelbar auf die Sichteinrichtung mit geringerer Geschwindigkeit aufgegebene Material abgebremst. Bei dessem ersten Durchlauf durch den Luftstrom der Luftblaseinrichtung findet ein erster Trennvorgang statt. Der Luftstrom unterstützt diese Trennung in der zweiten Phase des Trennvorgangs, wenn, wie vor beschrieben, die leichteren Teile gegen die Außenwand der Sichteinrichtung gedrückt werden. Durch die Sichteinrichtung wird die von der Zuführeinrichtung unmittelbar auf ihr aufgegebene Materialmischung gebremst und die schweren Teile erfahren hierdurch eine sich auf die Trennqualität äußerst vorteilhaft auswirkende Bewegungsumkehr. Hierdurch lösen sich die anhaftenden und im Windschatten der schwereren Teile sich befindenden leichteren Teile und werden vom Luftstrom der Lufteinblaseinrichtung erfaßt und mitgenommen. Somit ergibt sich durch die einfache Anordnung der Sichteinrichtung und der Aufgabe der Materialmischung auf die Außenseite der Sichteinrichtung eine bisher noch nicht annähernd erzielte Trennschärfe der Materialmischung.The material that is fed by the feed device onto the viewing device at a slower speed is braked by the viewing device. During its first pass through the air flow of the air blowing device, a first separation process takes place. The air flow supports this separation in the second phase of the separation process, if, as described above, the lighter parts are pressed against the outer wall of the sighting device. The viewing device brakes the material mixture applied directly to it by the feed device and the heavy parts are thereby subjected to a reversal of movement which has an extremely advantageous effect on the separation quality. As a result, the adhering lighter parts which are in the slipstream of the heavier parts are released and are caught and taken away by the air flow from the air blowing device. The simple arrangement of the classifying device and the task of mixing the material on the outside of the classifying device thus result in a level of selectivity of the classifying material that has not been achieved to date.

Um über die gesamte Breite der Vorrichtung eine gleichgute Trennung der Materialien zu gewährleisten, weist die Luftdüse eine Breite auf, die etwa der Breite der Sichteinrichtung entspricht. Anstelle einer einzigen Luftdüse können auch mehrere Luftdüsen nebeneinander und/oder übereinander angeordnet sein.In order to ensure an equally good separation of the materials over the entire width of the device, the air nozzle has a width that corresponds approximately to the width of the viewing device. Instead of a single air nozzle, a plurality of air nozzles can also be arranged side by side and / or one above the other.

Damit bei unterschiedlichster Zusammensetzung der zu trennenden Materialien eine gute Sichtung erreicht wird, ist die Luftblaseinrichtung in ihrer Höhe, ihrem Winkel und/oder in ihrer Entfernung zur Sichteinrichtung einstellbar.In order that a good sighting can be achieved with the most varied composition of the materials to be separated, the height, angle and / or distance of the air-blowing device can be adjusted to the sighting device.

Durch die einstellbare Zuordnung von Zuführeinrichtung und Sichteinrichtung ist eine individuelle Anpassung an die jeweils vorherrschenden Sicht- und Sortierbedingungen möglich. Der Abstand zwischen dem Abgabeende der Zuführeinrichtung und der Sichteinrichtung sollte um ein optimales Ergebnis zu erzielen das 1,5 bis 5-fache vorzugsweise das 2-3 fache des größten mittleren Durchmessers der Brocken der Materialmischung betragen. D.h. beispielsweise bei einem maximalen mittleren Brockendurchmesser einer Materialmischung von 30 mm ein Abstand von ca. 60 - 90 mm.The adjustable assignment of the feeding device and the viewing device enables individual adaptation to the prevailing viewing and sorting conditions. The distance between the discharge end of the feed device and the classifying device should be 1.5 to 5 times, preferably 2-3 times the largest average diameter of the chunks of the material mixture in order to achieve an optimal result. I.e. for example, with a maximum average chunk diameter of a material mixture of 30 mm, a distance of approx. 60 - 90 mm.

Besonders gute Ergebnisse beim Trennen unterschiedlichster Materialien wurden mit einer als Sichttrommel ausgebildeten Sichteinrichtung erzielt. Das Überraschende ist hierbei, daß in nicht vorhersehbarer Weise diese einfache Trommel bisher nicht erreichte Sicht- und Trennergebnisse bringt. Das zu sortierende Material wird unmittelbar von der Zuführeinrichtung auf die obere Hälfte der der Zuführeinrichtung zugewandten Außenfläche dieser rotierend angetriebenen Trommel aufgegeben. Durch den auf die obere Hälfte der der Zuführeinrichtung zugewandten Seite der Sichttrommel gerichteten Luftstrom werden die leichteren Materialien gegen die Außenwand der Sichttrommel gedrückt und durch den Luftstrom und die rotierende Sichttrommel fortgerissen, während die schweren Materialien vor der Sichttrommel, wie weiter oben beschrieben, nach unten fallen.Particularly good results when cutting a wide variety of materials were achieved with a classifying device designed as a classifying drum. The surprising thing here is that this simple drum brings unprecedented visual and separation results. The material to be sorted is fed directly from the feed device onto the upper half of the outer surface of this rotatingly driven drum facing the feed device. The airflow directed towards the upper half of the side of the viewing drum facing the feed device presses the lighter materials against the outer wall of the viewing drum and is carried away by the airflow and the rotating viewing drum, while the heavy materials in front of the viewing drum, as described above, go down fall.

Um eine noch weitere Steigerung der schon sehr hohen erfindungsgemäß mit einer Sichttrommel erreichten Trennung zu erreichen, kann vorgesehen werden, daß mehrere Sichttrommeln hintereinander angeordnet sind, denen jeweils eine Luftblaseinrichtung zugeordnet ist. Vorteilhaft kann sich diese Anordnung für das Sortieren von Materialmischungen auswirken, deren Bestandteile nach ihrer Form (Körperform) und/oder spezifischen Gewicht an sich relativ schwer trenn- und unterscheidbar sind.In order to achieve a further increase in the separation which has already been achieved with a viewing drum according to the invention, it can be provided that a plurality of viewing drums are arranged one behind the other, each of which is assigned an air blowing device. This arrangement can have an advantageous effect on the sorting of material mixtures, the components of which are relatively difficult to separate and distinguish themselves according to their shape (body shape) and / or specific weight.

Um ein optimales Sichtergebnis zu erreichen, kann es erforderlich sein, die Sichttrommel mit unterschiedlichen Drehzahlen anzutreiben.In order to achieve an optimal viewing result, it may be necessary to drive the viewing drum at different speeds.

Darüberhinaus ist in einer Ausführungsvariante vorgesehen, daß die Sichttrommel wahlweise in beide Drehrichtungen antreibbar ist. Die bevorzugte Drehrichtung der Sichttrommel ist die, bei der der obere Teil der Sichttrommel in Förderrichtung dreht.In addition, it is provided in an embodiment variant that the viewing drum can be driven in either direction of rotation. The preferred direction of rotation of the viewing drum is that in which the upper part of the viewing drum rotates in the conveying direction.

Unter besonders schwierigen Sicht- und Sortierverhältnissen ist es sinnvoll, daß auf der Innenseite der Wandung der Sichteinrichtung eine Vakuumeinrichtung angeordnet ist, daß die Wandung der Sichttrommel Durchbrüche aufweist, welche mit der Vakuumeinrichtung Zusammenwirken.Under particularly difficult viewing and sorting conditions, it makes sense that a vacuum device is arranged on the inside of the wall of the viewing device, that the wall of the viewing drum has openings which interact with the vacuum device.

Um bei schwierig zu trennenden Materialien ein ausreichend gutes Trennungsergebnis erzielen zu können, kann es sinnvoll sein, daß die Sichteinrichtung oder das Förderband auf ihrer Außenseite mit Ansätzen wie beispielsweise Noppen, Drahtstifte etc. besteht.In order to be able to achieve a sufficiently good separation result in the case of materials which are difficult to separate, it can be useful for the sighting device or the conveyor belt to have lugs such as knobs, wire pins etc. on its outside.

Die Vorrichtung weist die als Schwingförderer 1 ausgebildete Zuführeinrichtung und die als Sichttrommel 2 ausgebildete Sichteinrichtung auf. Der Schwingförderer 1 ist auf dem Rahmen 3 schwingend angeordnet und wird durch den Schwingungsantrieb 4 angetrieben. Vor dem Schwingförderer 1 ist das Zuführtransportband 5 angeordnet. In Förderrichtung 6 gesehen ist hinter dem Schwingförderer 1 die Sichttrommel 2 drehbar angeordnet. Die Sichttrommel 2 weist einen geschlossenen Außenmantel 7 auf und wird von einem nicht dargestellten Antriebsmotor in Pfeilrichtung 8 rotierend angetrieben. Der obere Punkt 9 der Sichttrommel 2 befindet sich im dargestellten Ausführungsbeispiel tiefer als das Abgabeende 10 des Schwingförderers 1. Die Drehachse 11 der Sichttrommel 2 ist quer zur Förderrichtung 6 des Schwingförderers 1 ausgerichtet, so daß die Sichttrommel 2 mit ihrer Drehachse 11 quer zur Förderrichtung 6 des Schwingförderers 1 angeordnet ist.The device has the feed device designed as a vibrating conveyor 1 and the viewing device designed as a viewing drum 2. The vibratory conveyor 1 is arranged in a vibrating manner on the frame 3 and is driven by the vibratory drive 4. The feed conveyor belt 5 is arranged in front of the vibrating conveyor 1. Seen in the conveying direction 6, the viewing drum 2 is rotatably arranged behind the vibrating conveyor 1. The viewing drum 2 has a closed outer casing 7 and is driven by a drive motor (not shown) rotating in the direction of the arrow 8. The upper point 9 of the viewing drum 2 is located lower than the discharge end 10 of the Vibrating conveyor 1. The axis of rotation 11 of the viewing drum 2 is aligned transversely to the conveying direction 6 of the vibrating conveyor 1, so that the viewing drum 2 is arranged with its axis of rotation 11 transversely to the conveying direction 6 of the vibrating conveyor 1.

Unterhalb der Sichttrommel ist auf der vorderen Seite der Sichttrommel 2 das Förderband 12 und auf der hinteren Seite das Förderband 13 angeordnet.The conveyor belt 12 is arranged below the viewing drum on the front side of the viewing drum 2 and the conveyor belt 13 on the rear side.

In dem Übergangsbereich 14 zwischen dem Schwingförderer 1 und der Sichttrommel 2 ist die Lufteinblaseinrichtung 15 mit der Luftdüse 16 angeordnet. Die Lufteinblaseinrichtung 15 ist über einen nicht dargestellten Schlauch mit einem ebenfalls nicht dargestellten Gebläse verbunden. Die Luftdüse 16 weist eine Breite auf, die etwa der Breite der Sichttrommel 2 wie Fig. 2 zeigt entspricht. Anstelle einer einzigen Luftdüse 16 können auch mehrere Luftdüsen nebeneinander und übereinander angeordnet sein. Die Luftdüse 16 ist in ihrer Höhe, ihrem Winkel sowie in ihrer Entfernung zur Sichttrommel 2 einstellbar. Im gezeigten Ausführungsbeispiel ist der aus der Luftdüse 16 austretende Luftstrom, wie durch den Pfeil 17 angedeutet ist, etwa tangential zur oberen Hälfte der dem Schwingförderer 1 zugewandten Seite der Sichttrommel 2 gerichtet.The air injection device 15 with the air nozzle 16 is arranged in the transition region 14 between the vibratory conveyor 1 and the viewing drum 2. The air injection device 15 is connected via a hose, not shown, to a blower, also not shown. The air nozzle 16 has a width which corresponds approximately to the width of the viewing drum 2 as shown in FIG. 2. Instead of a single air nozzle 16, a plurality of air nozzles can also be arranged side by side and one above the other. The air nozzle 16 is adjustable in height, its angle and in its distance from the viewing drum 2. In the exemplary embodiment shown, the air stream emerging from the air nozzle 16, as indicated by the arrow 17, is directed approximately tangentially to the upper half of the side of the viewing drum 2 facing the vibrating conveyor 1.

Die Sichttrommel 2 ist über ihren Antriebsmotor mit unterschiedlichen Drehzahlen sowie wahlweise in beide möglichen Drehrichtungen antreibbar, wobei die Sichttrommel 2 in dem Ausführungsbeispiel in Pfeilrichtung 8 angetrieben wird. Weiterhin ist die Sichttrommel 2 an dem Rahmen 18 in Höhenrichtung verstell- und einstellbar angeordnet, so daß der obere Punkt 9 (Scheitelpunkt) tiefer, auf gleicher Höhe oder höher als der Abgabepunkt 10 des Schwingförderers 1 eingestellt werden kann.The viewing drum 2 can be driven via its drive motor at different speeds and optionally in both possible directions of rotation, the viewing drum 2 being driven in the direction of arrow 8 in the exemplary embodiment. Furthermore, the viewing drum 2 is arranged on the frame 18 so as to be adjustable and adjustable in height, so that the upper point 9 (apex) can be set lower, at the same height or higher than the delivery point 10 of the vibratory conveyor 1.

Darüberhinaus kann die Sichttrommel 2 in nicht dargestellter Weise in verschiedenen Abständen zu dem Abgabeende 10 des Schwingförderers 1 eingestellt werden. Auch die Förderbänder 12 und 13 können zu der Sichttrommel 2 in nicht dargestellter Weise eingestellt werden.In addition, the viewing drum 2 can be adjusted in a manner not shown at different distances from the discharge end 10 of the vibratory conveyor 1. The conveyor belts 12 and 13 can also be adjusted to the viewing drum 2 in a manner not shown.

Die aus der Luftdüse 16 austretende Luftmenge sowie die Geschwindigkeit, mit der die Luft aus der Luftdüse 16 austritt, ist über eine nicht dargestellte Reguliereinrichtung einstellbar.The amount of air emerging from the air nozzle 16 and the speed at which the air exits the air nozzle 16 can be adjusted via a regulating device (not shown).

Die Funktionsweise der Trennvorrichtung gemäß Fig. 1 ist folgende:

  • Die zu sortierende und zu trennende Materialmischung aus Materialien mit unterschiedlichem spezifischen Gewicht (wie beispielsweise Steinschutt, Folien, Styropor, Papier, Holz etc.) wird beispielsweise aus einem Vorratsbunker mittels des Förderbandes 5, wie durch den Pfeil 19 angedeutet ist, auf den Schwingförderer 1 aufgegeben. Der Schwingförderer 1 fördert die Materialmischung in vergleichsmäßigender Weise in Pfeilrichtung 6 weiter. Am Abgabepunkt 10 des Schwingförderers 1 werden die verschiedenen Materialteile der Materialmischung gegen die obere Hälfte der dem Schwingförderer 1 zugewandten Seite des Außenmantels 7 der in Pfeilrichtung 8 rotierenden Sichttrommel 2 geleitet. Die Sichttrommel 2 rotiert mit einer geringen Umfangsgeschwindigkeit, angeglichen an die Geschwindigkeit des Materialstromes. Durch den aus der Luftdüse 16 austretenden Luftstrom, der durch den Pfeil 17 angedeutet ist, werden vor allem die Materialteile, die ein geringes spezifisches Gewicht besitzen, wie Folien, Papier, Styropor etc., gegen den Außenmantel 7 der Sichttrommel 2 gedrückt. Hierdurch wird die Reibungskraft zwischen diesen "leichten" Materialteilen und dem Außenmantel 7 der Sichttrommel 2 erhöht. Diese "leichten" Materialteile werden durch die Drehbewegung der Sichttrommel 2, unterstützt von dem Luftstrom 17, in Pfeilrichtung 20 mitgenommen und fallen dann anschließend auf das Förderband 13. Das Förderband 13 fördert diese aussortierten "leichten" Materialien dann zu einem Behälter oder zu einer Auffangstation. Die schweren Materialteile der Materialmischung prallen gegen den Außenmantel 7 der Sichttrommel 2 und werden durch die Sichttrommel 2 abgebremst, von der Sichttrommel 2 aufgrund der Aufprallenergie in den Luftstrom zurückgeworfen. Hierbei lösen sich anhaftende und sich im Windschatten befindende leichte Teile von den schwereren zurückgeworfenen Teilen, so daß diese leichten Teile von dem Luftstrom 17 erfaßt und fortgerissen werden. Die schweren Teile fallen dann nach unten auf der Förderband 12. Das Förderband 12 fördert diese separierten "schweren" Materialteile zu einem anderen Behälter oder Lagerplatz. Am Außenmantel 7 anhaftende Teile werden durch den Abstreifer 21 vom Außenmantel abgeschabt.
1 works as follows:
  • The material mixture to be sorted and separated from materials with different specific weights (such as rubble, foils, polystyrene, paper, wood, etc.) is, for example, from a storage bunker by means of the conveyor belt 5, as indicated by arrow 19, onto the vibratory conveyor 1 given up. The vibrating conveyor 1 conveys the material mixture in a comparative manner in the direction of the arrow 6. At the delivery point 10 of the vibrating conveyor 1, the various material parts of the material mixture are directed against the upper half of the side of the outer jacket 7 of the viewing drum 2 rotating in the direction of the arrow 8 facing the vibrating conveyor 1. The viewing drum 2 rotates at a low peripheral speed, adapted to the speed of the material flow. Due to the air flow emerging from the air nozzle 16, which is indicated by the arrow 17, especially the material parts that have a low specific weight, such as foils, paper, polystyrene, etc., are pressed against the outer jacket 7 of the viewing drum 2. This increases the frictional force between these "light" material parts and the outer jacket 7 of the viewing drum 2. These "light" material parts are carried by the rotary movement of the viewing drum 2, supported by the air flow 17, in the direction of arrow 20 and then fall onto the conveyor belt 13. The conveyor belt 13 then conveys these sorted "light" materials to a container or to a collecting station . The heavy material parts of the material mixture collide against the outer jacket 7 of the viewing drum 2 and are braked by the viewing drum 2 and thrown back into the air flow by the viewing drum 2 due to the impact energy. Here, adhering and in the slipstream light parts detach from the heavier parts thrown back, so that these light parts are caught by the air stream 17 and torn away. The heavy parts then fall down on the conveyor belt 12. The conveyor belt 12 conveys these separated "heavy" material parts to another container or storage location. Parts adhering to the outer jacket 7 are scraped off the outer jacket by the stripper 21.

Die Fig. 3 zeigt eine weitere Möglichkeit der Zuordnung von einer als Schwingförderer 1' ausgebildeten Zuführeinrichtung und einer als Sichttrommel 2' ausgebildeten Sichteinrichtung. Die Sichttrommel 2' ist mit ihrer Drehachse 11 im Winkel alpha zu der Förderrichtung 6' des Schwingförderers 1' angestellt. Das Abgabeende 10' des Schwingförderers 1' verläuft in der Draufsicht gesehen annähernd parallel zur Drehachse 11' der Sichttrommel 2'.FIG. 3 shows a further possibility of assigning a feed device designed as an oscillating conveyor 1 'and a viewing device designed as a viewing drum 2'. The viewing drum 2 'is set with its axis of rotation 11 at an angle alpha to the conveying direction 6' of the vibratory conveyor 1 '. The discharge end 10 'of the vibratory conveyor 1', viewed in plan view, runs approximately parallel to the axis of rotation 11 'of the viewing drum 2'.

Die in Fig. 4 dargestellte Sichttrommel 22 ist anstelle der Sichttrommel 2 in die in Fig. 1 dargestellte Trennvorrichtung bei schwierigen Trennungsbedingungen einsetzbar. Diese Sichttrommel 22 ist mit einer Vakuumeinrichtung 23 ausgerüstet. Die Vakuumeinrichtung 23 ist auf der Innenseite 24 des Außenmantels 25 der Sichttrommel 22 angeordnet. Die Vakuumeinrichtung 23 weist die bogenförmige Vakuumkammer 26 auf, welche sich zumindest annähernd über die obere Hälfte der der Zuführeinrichtung zugewandten Seite der Sichttrommel 21 erstreckt, wie Fig. 4 zeigt. Die Vakuumkammer 26 ist über einen Schlauch 27 mit einer nicht dargestellten Einrichtung (beispielsweise Sauggebläse) verbunden. Zur Regulierung des Vakuums kann eine nicht dargestellte Regeleinrichtung vorgesehen werden. Der Außenmantel 25 der Sichttrommel 22 weist die über den Umfang und Breite verteilten Durchbrüche 28 auf, die im Bereich der Vakuumkammer 26 mit einem Unterdruck beaufschlagt werden. Über diesen an den Durchbrüchen 28 anliegenden Unterdruck werden die von dem Schwingförderer 1 gemäß Fig. 1 aufgegebenen "leichteren" Materialteile gegen die Außenfläche des Außenmantels 24 der Sichttrommel 22 gezogen, so daß diese leichten Materialteile sicher in Pfeilrichtung 20 gefördert werden. Bei dem Erreichen des Endes 29 der Vakuumkammer 26 wird der Unterdruck an den Durchbrüchen 28 unterbrochen, 50 daß die Materialteile ab diesem Punkt beim Weiterdrehen der Sichttrommel 22 nicht mehr angesaugt werden. Im übrigen ist die Funktionsweise der Sichttrommel 22 gleich der in Fig. 1 dargestellten Sichttrommel.The sighting drum 22 shown in FIG. 4 can be used instead of the sighting drum 2 in the separating device shown in FIG. 1 in difficult separation conditions. This viewing drum 22 is equipped with a vacuum device 23. The vacuum device 23 is arranged on the inside 24 of the outer casing 25 of the viewing drum 22. The vacuum device 23 has the arcuate vacuum chamber 26, which is at least approximately over the upper half of the Feed device facing side of the viewing drum 21 extends, as shown in FIG. 4. The vacuum chamber 26 is connected via a hose 27 to a device (not shown) (for example a suction fan). A regulating device (not shown) can be provided to regulate the vacuum. The outer jacket 25 of the viewing drum 22 has the openings 28 which are distributed over the circumference and width and which are subjected to a negative pressure in the region of the vacuum chamber 26. The "lighter" material parts given up by the vibratory conveyor 1 according to FIG. 1 are drawn against the outer surface of the outer casing 24 of the viewing drum 22 via this vacuum, which is applied to the openings 28, so that these light material parts are conveyed safely in the direction of the arrow 20. When the end 29 of the vacuum chamber 26 is reached, the negative pressure at the openings 28 is interrupted, 50 so that the material parts are no longer sucked in from this point on when the viewing drum 22 is rotated further. Otherwise, the mode of operation of the viewing drum 22 is the same as the viewing drum shown in FIG. 1.

Die Sichttrommel 30, gemäß Fig. 5, ist anstelle der Sichttrommel 2 in die Fig. 1 dargestellte Trennvorrichtung bei schwierigen Sicht- und Trennbedingungen einsetzbar. Die Sichttrommel 30 weist auf der Außenseite ihres Außenmantels 31 die auf ihrem Umfang und ihrer Breite verteilten Noppen oder Queransätze 32 auf. Hierdurch wird die Trennwirkung der Sichttrommel 30 vor allem beim Sortieren und Sichten von Materialteilen ähnlicher Form erheblich verbessert.The sight drum 30, according to FIG. 5, can be used instead of the sight drum 2 in the separating device shown in FIG. 1 in difficult sight and separation conditions. The viewing drum 30 has on the outside of its outer jacket 31 the knobs or transverse projections 32 distributed over its circumference and its width. As a result, the separating effect of the viewing drum 30 is considerably improved, especially when sorting and viewing material parts of a similar shape.

Die Fig. 6 zeigt, daß anstelle einer einzigen Sichttrommel, wie in Fig. 1, mehrere Sichttrommeln 33 hintereinander, in Sichtrichtung 34 gesehen, angeordnet werden können. Wie in Fig. 6 entnommen werden kann, ist die jeweils in Sichtrichtung 34 gesehene nachgeordnete Sichttrommel 33 tiefer als die vorhergehende angeordnet. Jeder Sichttrommel 33 ist eine als Luftdüse 35 ausgebildete Luftblaseinrichtung zugeordnet. In nicht dargestellter Weise sind die Sichttrommeln 33 in ihren Abständen (Höhen (A) - und/oder Folgeabstand (B)) zueinander ein- und verstellbar; d.h. diese Abstände sind den Erfordernissen entsprechend variabel. Die Drehachsen 36 der Sichttrommel 33 können auf einer geraden oder gekrümmten (konvex oder konkav) Linie angeordnet sein. Es ist auch möglich, Sichttrommeln 33 mit unterschiedlichen Außendurchmesser hintereinander anzuordnen.FIG. 6 shows that instead of a single viewing drum, as in FIG. 1, a plurality of viewing drums 33 can be arranged one behind the other, viewed in the viewing direction 34. As can be seen in FIG. 6, the downstream viewing drum 33 seen in the viewing direction 34 is arranged lower than the previous one. An air blowing device designed as an air nozzle 35 is assigned to each viewing drum 33. In a manner not shown, the viewing drums 33 can be adjusted and adjusted in their distances (heights (A) and / or subsequent distance (B)) from one another; i.e. these distances can be varied as required. The axes of rotation 36 of the viewing drum 33 can be arranged on a straight or curved (convex or concave) line. It is also possible to arrange viewing drums 33 with different outer diameters one behind the other.

Die Fig. 7 zeigt den Einsatz eines Förderbandes 37 anstelle der in Fig. 1 dargestellten Sichttrommel 2.FIG. 7 shows the use of a conveyor belt 37 instead of the viewing drum 2 shown in FIG. 1.

Das Förderband 37 ist schräg nach oben angestellt und auf seiner Sichtseite 38 bogenförmig gekrümmt geführt. Wie durch den Pfeil 20 angedeutet ist, wird das "leichtere" Material auf das Förderband 13 geleitet, während das "schwerere" Material auf das Förderband 12 fällt.The conveyor belt 37 is positioned obliquely upwards and is guided in an arcuate manner on its visible side 38. As indicated by the arrow 20, the "lighter" material is conveyed onto the conveyor belt 13, while the "heavier" material falls onto the conveyor belt 12.

Im übrigen sei bemerkt, daß der Trennungsvorgang der Materialmischung gemäß den Anlagen nach der Figur 7 dem Trennvorgang, wie für die Anlage gemäß Fig. 1 beschrieben ist, entspricht.Moreover, it should be noted that the separation process of the material mixture according to the plants according to FIG. 7 corresponds to the separation process as described for the plant according to FIG. 1.
