Description

Vorrichtung zum Trennen einer Materialmischung und Ver- fahren zum Trennen einer Materialmischung  Device for separating a material mixture and method for separating a material mixture
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 eine Vorrichtung zum Trennen einer Materialmischung, wobei eine Materialtrennung durch einen Fallbereich auf einem La ufband mittel 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. A device for separating a material mixture is known, wherein a material separation by a fall region on a La ufband means for transporting at least a portion of the material mixture is to be made in a transport direction. The disadvantage is that the separation of the material mixture is not complete, several material mixture parts are superimposed on the treadmill means. In particular, the separation of plastic can not be done in necessary pure form.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zum Trennen einer Ma- terialmischung bereitzustellen, die eine einfache und sichere Materialtrennung ermöglicht, insbesondere bei einem verschmutzten Kompostmaterial. The object of the present invention is to provide a device for separating a material mixture, which enables a simple and reliable material separation, in particular in the case of a soiled compost material.
Die Aufgabe wird gelöst durch eine Vorrichtung zum Trennen einer Materialmischung, insbesondere Abfallmaterial, insbesondere Kunststoff und/oder Bioabfall, umfassend ein insbesondere neigungseinstellbares Laufbandmittel zum Transport zumindest eines Teils der Materialmischung in einer Transportrichtung, wobei die Materiamischung insbesondere in einer Transportbreite im Wesentlichen gleichmäßig verteilt auf dem Laufbandmittel aufgebracht ist, ein Fallbereich zur Erzeugung eines fallenden Materialstromes der Materialmischung für auf dem La ufband mittel transportierte Materialmischung in Transportrichtung an einem Unterbrechungsbereich des Laufbandmittels, wobei insbesondere das Laufbandmittel eine angepasste Trans- portgeschwindigkeit aufweist, so dass die Materialmischung im Unterbrechungsbereich im Wesentlichen in einer vorgegebenen Parabelkurve abfällt, ein Luftströmungsmittel zur Erzeugung eines insbesondere gerichteten Luftstromes, insbesondere mit einem einstellbaren Strömungswinkel, wobei das Luftströmungsmittel im Wesentlichen entgegen der Transportrichtung der Materialmischung auf den zumin- dest teilweise frei fallenden Materialstrom gerichtet ist. The object is achieved by a device for separating a material mixture, in particular waste material, in particular plastic and / or biowaste, comprising a tread adjustment means, in particular tiltable for transporting at least a portion of the material mixture in a transport direction, wherein the A fall region for generating a falling material flow of the material mixture for conveyed on the La ufband medium material mixture in the transport direction at an interrupting region of the treadmill means, in particular the treadmill means has an adapted transport speed so that the material mixture in the interruption region drops substantially in a predetermined parabolic curve, an air flow means for generating a particularly directed air flow, in particular with an adjustable flow angle, wherein the air flow means directed against the transport direction of the material mixture to the at least partially freely flowing material flow substantially is.
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 Transportge- schwindigkeit 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 Materi- al, 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 makes it possible by the transport direction of the material of a conveyor belt to accelerate the material counterflowing air increased selection of different materials in the falling material flow by a driving apart in the air flow direction. By the opposite flow direction, the width of the distribution of the different material flow parts is increased, so that in the area of the impact on the ground or on a treadmill for the removal of the separated materials a clean separation is possible. When the treadmill means has an adapted, sufficiently high transport speed, the material mixture drops substantially in a predetermined parabolic curve in the interruption region, which, in combination with the countercurrent air, enables a stronger, supportive separation of the materials while at the same time saving energy for producing the air flow. For example, in a compost contaminated with plastic a separation in the opposite to the transport direction separated plastic and the further flowing heavier material flow possible. Due to the fact that the running speed can be adjusted, particles of different weights can be sent to different parabolic paths. Lightweight material, such as plastic film, first delays, supported by the blower, heavy material, such as stones, glass, metals, flying furthest. In an intermediate area is the medium-heavy material, such as wood, organic. This separation by the parabola is advantageous for other streams, such as crushed, plastic-contaminated scrap, suitable as biowaste.
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 Ein- Stellung 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 einge- richtet, da dies den Abscheidegrad der Materialien erhöht. By arranging a plurality of air nozzles and / or an air channel with laminar, volume-controllable outflow, for example, an air grid, which are directed to the free-fall material flow, the separation is further improved. A regulation can be effected, for example, by means of frequency converters for the fan or by adjusting flaps or slides in the line and by means of an adjustable angle of incidence of the laminar flow to the sloping material flow, for example by mechanical adjustment of the air nozzles or the air grille, a further sensitive input. Positioning and separation are carried out even after the smallest material differences, which is possible in particular with materials with similar air resistance, two or more soft-air classifier one behind the other and / or side by side to increase the Abscheideleistung depending on the degree of contamination. Advantageously, the material supply and distribution in the sense of a uniform distribution on the entire width of the conveyor belt set up, since this increases the separation efficiency 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 kön- nen. 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 space area for air calming offers, in particular, an encapsulation which, in addition to calming the air, can also provide detection of the blown out lightweight materials, which can then be carried away, for example, with a removal belt. The room area also provides protection against external wind influences and a dust catch. The design may 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 fluid can be removed from the encapsulated space, so that a recirculation mode is largely possible. This is a great advantage since no further exhaust air treatment with regard to, for example, dust and / or odor is required.
Vorteilhaft ist es, wenn das Luftströmungsmittel ein oder mehrere Luftdüsenmittel umfasst, die insbesondere nebeneinander und/oder hintereinander und/oder übereinander angeordnet sind. Vorteilhaft ist es, wenn das Luftströmungsmittel ein Luftkanalmittel mit laminarer, insbesondere im Volumen regelbarer Anströmung umfasst.

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