Description

Die Erfindung betrifft eine Vorrichtung zum Trennen einer Materialmischung nach dem Oberbegriff von Anspruch 1 und ein Verfahren zum Trennen einer Materialmischung nach Anspruch 10.The invention relates to a device for separating a material mixture according to the preamble of claim 1 and a method for separating a material mixture according to claim 10.

Bekannt ist, zum Beispiel aus DE 1178022 B , eine Vorrichtung zum Trennen einer Materialmischung, wobei eine Materialtrennung durch einen Fallbereich auf einem Laufbandmittel zum Transport zumindest eines Teils der Materialmischung in einer Transportrichtung vorzunehmen ist. Nachteilig ist es, dass die Trennung der Materialmischung nicht vollständig erfolgt. mehrere Materialmischungsteile überlagern sich auf dem Laufbandmittel. Insbesondere die Abtrennung von Kunststoff kann nicht in notwendiger reiner Form erfolgen. Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zum Trennen einer Materialmischung bereitzustellen, die eine einfache und sichere Materialtrennung ermöglicht, insbesondere bei einem verschmutzten Kompostmaterial.Is known, for example, from DE 1178022 B , a device for separating a material mixture, wherein a material separation is to be carried out by a fall area on a conveyor belt means for transporting at least a part of the material mixture in one transport direction. It is disadvantageous that the material mixture is not completely separated. several material mixture parts are superimposed on the treadmill means. In particular, the separation of plastic cannot take place in the necessary pure form. The object of the present invention is to provide a device for separating a material mixture which enables simple and reliable material separation, in particular in the case of contaminated compost material.

Die Aufgabe wird gelöst durch eine Vorrichtung nach Anspruch 1.The object is achieved by a device according to claim 1.

Die Erfindung ermöglicht durch die der Transportrichtung des Materials eines Transportbandes zur Beschleunigung des Materials entgegen strömenden Luft eine verstärkte Selektion von unterschiedlichen Materialien im fallenden Materialstrom durch ein Auseinandertreiben in Luftstromrichtung. Durch die entgegengesetzte Strömungsrichtung wird die Weite der Verteilung der unterschiedlichen Materialstromteile vergrößert, so dass im Bereich des Auftreffens am Boden bzw. auf einem Laufband zum Abtransport der abgetrennten Materialien eine saubere Trennung möglich wird. Wenn das Laufbandmittel eine angepasste, ausreichend hohe Transportgeschwindigkeit aufweist, fällt die Materialmischung im Unterbrechungsbereich im Wesentlichen in einer vorgegebenen Parabelkurve ab, wobei dies in Kombination mit der entgegenströmenden Luft eine stärkere, unterstützende Trennung der Materialien ermöglicht unter gleichzeitiger Einsparung von Energie zur Erzeugung des Luftstromes. Beispielsweise wird bei einem mit Kunststoff verschmutzten Kompost eine Trennung in den entgegen der Transportrichtung abgetrennten Kunststoff und den weiter fliegenden schwereren Materialstrom möglich. Dadurch,. dass die Laufgeschwindigkeit einstellbar ist, können unterschiedlich schwere Partikel gezielt auf unterschiedliche Parabelbahnen geschickt werden. Leichtes Material, beispielsweise Folienkunststoffe, verzögert zuerst, unterstützt durch das Gebläse, schweres Material, beispielsweise Steine, Glas, Metalle, fliegen am weitesten. In einem Zwischenbereich liegt das mittelschwere Material, beispielsweise Holz, Organik. Diese Trennung durch die Wurfparabel ist vorteilhaft auch für andere Stoffströme, beispielsweise zerkleinerter, mit Kunststoff verschmutzter Schrott, als Bioabfall geeignet.The invention enables an increased selection of different materials in the falling material flow by being driven apart in the air flow direction by means of the air flowing in the opposite direction to the transport direction of the material of a conveyor belt in order to accelerate the material. Due to the opposite flow direction, the width of the distribution of the different material flow parts is increased, so that a clean separation is possible in the area of impact on the floor or on a conveyor belt for the removal of the separated materials. If the treadmill has an adapted, sufficiently high transport speed, the material mixture in the interruption area essentially falls in a predetermined parabolic curve, which in combination with the counter-flowing air enables a stronger, supporting separation of the materials while at the same time saving energy for generating the air flow. For example, a compost contaminated with plastic can be separated into the plastic separated in the opposite direction to the transport direction and the heavier material flow that continues to fly. Through this,. The fact that the running speed is adjustable means that particles of different weights can be sent to different parabolic paths in a targeted manner. Light material, for example foil plastics, decelerates first, supported by the fan, heavy material, for example stones, glass, metals, fly the farthest. The medium-weight material, for example wood, organic material, lies in an intermediate area. This separation Due to the trajectory parabola, it is also advantageously suitable as biowaste for other material flows, for example shredded scrap contaminated with plastic.

Durch eine Anordnung mehrerer Luftdüsen und/oder einem Luftkanal mit laminarer, im Volumen regelbarer Ausströmung, beispielsweise eines Luftgitter, die auf den Freifall-Materialstrom gerichtet sind, wird die Trennung noch weiter verbessert. Eine Regelung kann beispielsweise über Frequenzumformer für den Ventilator oder durch Stellklappen, bzw. -schieber in der Leitung erfolgen und mit Hilfe eines einstellbaren Anstellwinkels der laminaren Strömung zum abfallenden Materialstrom, beispielsweise durch mechanische Einstellung der Luftdüsen bzw. des Luftgitters kann eine weitere sensible Einstellung und Trennung auch nach kleinsten Materialunterschieden erfolgen, was insbesondere auch bei Materialien mit ähnlichem Luftwiderstand möglich ist, zwei oder mehrere Soft-Air-Sichter hintereinander und/oder nebeneinander zu schalten, um je nach Verschmutzungsgrad die Abscheideleistung zu erhöhen. Vorteilhaft ist die Materialzuführung und -verteilung im Sinne einer gleichmäßigen Verteilung auf gesamter Breite des Transportbandes eingerichtet, da dies den Abscheidegrad der Materialien erhöht.By arranging several air nozzles and / or an air duct with a laminar, volume-adjustable outflow, for example an air grille, which are directed towards the free-fall material flow, the separation is improved even further. A regulation can take place, for example, via frequency converters for the fan or by adjusting flaps or slides in the line and with the help of an adjustable angle of incidence of the laminar flow to the falling material flow, for example by mechanical setting of the air nozzles or the air grille, a further sensitive setting and Separation takes place even after the smallest material differences, which is also possible in particular with materials with similar air resistance, to switch two or more soft-air classifiers one behind the other and / or next to one another in order to increase the separation efficiency depending on the degree of pollution. The material supply and distribution is advantageously set up in the sense of a uniform distribution over the entire width of the conveyor belt, since this increases the degree of separation of the materials.

Der Raumbereich zur Luftberuhigung bietet insbesondere eine Kapselung die neben der Luftberuhigung auch eine Erfassung der herausgeblasenen Leichtstoffe bieten kann, die dann beispielsweise mit einem Abtransportband abgefördert werden können. Der Raumbereich bietet auch Schutz vor Fremdwindeinflüssen und einen Staubfang. Die Ausführung kann beispielsweise teilweise als Lochblech mit kleinen Öffnungen vorgesehen sein, damit die überschüssige Luft entweichen kann. Die Zuluft für den Ventilator/en des Luftströmungsmittels kann aus dem gekapselten Raum entnommen werden, so dass ein Umluftbetrieb weitestgehend möglich ist. Dies ist ein großer Vorteil, da so keine weitere Abluftbehandlung hinsichtlich beispielsweise Staub und/oder Geruch nötig wird.The room area for calming the air offers in particular an encapsulation which, in addition to calming the air, can also provide a detection of the light substances blown out, which can then be conveyed away, for example, with a removal belt. The room area also offers protection from external wind influences and a dust catcher. The design can for example be partially provided as a perforated plate with small openings so that the excess air can escape. The supply air for the fan (s) of the air flow means can be taken from the encapsulated room, so that a circulating air operation is largely possible. This is a great advantage since no further exhaust air treatment with regard to dust and / or odor, for example, is necessary.

Vorteilhaft ist es, wenn ein Regelungsmittel für das Luftströmungsmittel vorgesehen ist, insbesondere umfassend einen Frequenzumformer, wobei insbesondere ein regelbarer Luftstromerzeuger, insbesondere ein Ventilator zur Erzeugung einer Luftbewegung hinter einem oder mehreren Luftdüsenmitteln und/oder Luftgittermitteln vorgesehen ist.It is advantageous if a control means is provided for the air flow means, in particular comprising a frequency converter, in particular a controllable air flow generator, in particular a fan for generating an air movement behind one or more air nozzle means and / or air grille means being provided.

Vorteilhaft ist es, wenn ein Regelungsmittel für das Luftströmungsmittel Stellklappen und/oder Stellschieber umfasst.It is advantageous if a regulating means for the air flow means comprises adjusting flaps and / or adjusting slides.

Vorteilhaft ist es, wenn das Laufbandmittel und/oder der Fallbereich zumindest teilweise durch ein Kammermittel in einem Raumbereich zur Luftberuhigung und/oder Schwebstofffang eingefasst ist, insbesondere umfassend eine Gitterkammer und/oder eine Lochblechkammer.It is advantageous if the treadmill means and / or the fall area is at least partially enclosed by a chamber means in a room area for calming air and / or catching suspended matter, in particular comprising a lattice chamber and / or a perforated plate chamber.

Vorteilhaft ist es, wenn Luft aus dem Raumbereich zur Luftberuhigung mittels eines Rückführungsmittels rückführbar zum Luftströmungsmittel ist.It is advantageous if air from the room area can be returned to the air flow means by means of a return means for calming the air.

Vorteilhaft ist es, wenn ein Trennmittel zur Separierung von unterschiedlich weit getragenen Materialen aus der Materialmischung nach dem Fall vom Laufbandmittel vorgesehen ist, insbesondere eine Materialtrennwand und/oder dass getrennte Materialien durch ein oder mehrere Abtransportbänder ableitbar sind.It is advantageous if a separating means is used for separating materials that have been carried to different distances from the material mixture after they have fallen from the treadmill means is provided, in particular a material partition and / or that separate materials can be diverted by one or more removal belts.

Die Aufgabe wird gelöst durch ein Verfahren nach Anspruch 10.The object is achieved by a method according to claim 10.
