Description

Die vorliegende Erfindung betrifft einen Steinabscheider mit Windsichter zur Aufarbeitung eines Materialgemisches und ein Verfahren hierfür.The present invention relates to a stone separator with air classifier for processing a material mixture and a method thereof.

Derartige Vorrichtungen sind aus dem Stand der Technik bekannt und dienen zur Aufbereitung von Materialgemischen wie zum Beispiel Biomasse, wobei in der Biomasse enthaltene Fremdkörper, wie z. B. Steine, Folien oder ähnliche Bestandteile, separiert werden. Hierzu ist es bekannt, zum Beispiel das unterschiedliche Fall-verhalten der unterschiedlichen Bestandteile des Materialgemisches zu nutzen oder beispielsweise unterschiedliche Bestandteile mittels von Gebläsen oder Absaugvorrichtungen abzusaugen und dabei das unterschiedliche fluiddynamische Verhalten der Bestandteile zu deren Trennung zu nutzen.Such devices are known from the prior art and are used for the preparation of material mixtures such as biomass, wherein contained in the biomass foreign bodies such. As stones, films or similar components are separated. For this purpose, it is known, for example, to use the different case behavior of the different constituents of the material mixture or, for example, to aspirate different constituents by means of blowers or suction devices and thereby to use the different fluid-dynamic behavior of the constituents for their separation.

Problematisch kann es dabei sein, dass sich z. B. Steine auf von einer Absaugvorrichtung abzusaugende Komponenten, wie z. B. Folien oder andere Leichtstoffe legen und diese deshalb dann von der Absaugvorrichtung nicht mehr oder nicht mehr gut genug abgesaugt werden können. Generell kann es problematisch sein, Steine, Inertstoffe und/oder Schwerteile, die sich wie beschrieben auf die Leicht-Stoffe legen können aus der Inputfraktion bzw. aus dem in die Vorrichtung eingebrachten Materialgemisch zu separieren.The problem may be that z. B. stones on to be sucked by a suction device components such. As foils or other lightweight materials and therefore they can not be sucked off the suction or not good enough. Generally it can be problematic to stones, inert materials and / or heavy parts, which are as described on the light fabrics can be separated from the input fraction or from the material mixture introduced into the device.

Aufgabe der vorliegenden Erfindung ist es daher, eine verbesserte Vorrichtung zum Aufbereiten eines Materialgemisches bereitzustellen, welche die genannten Nachteile überwindet.The object of the present invention is therefore to provide an improved apparatus for processing a material mixture which overcomes the disadvantages mentioned.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung zur Aufarbeitung eines Materialgemisches mit den Merkmalen des Anspruchs 1 gelöst. Die Vorrichtung dient insbesondere zum Abscheiden von Steinen, Inertstoffen und/oder Schwerteilen mit einem ersten Förderband, das mit einer Kammer verbunden ist, wobei im Innenraum der Kammer mindestens ein Druckgebläse zum Erzeugen eines von unten auf das in die Kammer einfallende Materialgemisch gerichteten Luftstroms vorgesehen ist, wobei mindestens zwei Auffangmittel versetzt entlang des Kammerbodens mit unterschiedlichem Abstand zur kammerseitigen Eintrittsstelle des Materialgemisches eingeordnet und durch mindestens einen am Kammerboden beweglich angeordneten Trennscheitel, welcher sich vom Kammerboden in Richtung der Kammeroberseite erstreckt, flächenmäßig voneinander abgegrenzt sind, wobei in einem ersten Trennbereich eine erste Materialgruppe wie Steine und/oder Inertstoffe und/oder Schwerteile mit dem geringsten Fluidwiderstand aller Materialgruppen des Materialgemisches von dem Materialstrom wenigstens teilweise abtrennbar ist, wobei die Vorrichtung von einem Fluidstrom und einem mittels der Vorrichtung trennbaren Materialgemisch wenigstens dreier unterschiedlicher Materialgruppen als Materialstrom durchströmbar ist, und wobei in einem zweiten Trennbereich mit einer Beruhigungszone und mit einem ersten Unterdruckbereich eine zweite Materialgruppe wenigstens teilweise mittels des ersten Unterdruckbereichs in einer horizontal seitlichen Richtung von einer Hauptrichtung des Materialstroms und von der Beruhigungszone abtrennbar ist.This object is achieved by a device for processing a material mixture with the features of claim 1. The device is used in particular for separating stones, inert materials and / or heavy parts with a first conveyor belt, which is connected to a chamber, wherein in the interior of the chamber at least one pressure blower for generating a directed from below to the incident material in the chamber material mixture air flow is provided , wherein at least two collecting means offset along the chamber bottom with different distance to the chamber side entry point of the material mixture and separated by at least one movable on the bottom of the chamber separating vertex which extends from the chamber bottom in the direction of the chamber top, are separated from each other in terms of area, wherein in a first separation area a first Material group such as stones and / or inert materials and / or heavy parts with the least fluid resistance of all material groups of the material mixture of the material flow is at least partially separated, wherein the device of a Fluidstro m and a separable by means of the device material mixture of at least three different material groups as a material flow, and wherein in a second separation region with a calming zone and with a first negative pressure region, a second material group at least partially by means of the first negative pressure region in a horizontal lateral direction of a main direction of the material flow and is separable from the calming zone.

Dabei ist für das Absaugen der leichteren Materialstrombestandteile vorteilhaft, dass diese mitsamt dem Fluidstrom in der Beruhigungszone des zweiten Trennbereichs stromabwärts eines Fluidleitblechs oder mehrere Fluidleitbleche in ihrer Bewegung verlangsamt und geführt werden und so einfacher mittels des ersten Unterdruckbereichs vom Materialstrom abtrennbar sind. Hierbei treten keine oder geringere Verwirbelungen im Bereich der Steine und/oder Inertstoffe auf, so dass keine Leichtstoffe zurück in die Fraktion bzw. Materialgruppe der Steine/Inertstoffe/Schwerteile zurückströmen können. Auch ist die Absaugung im Bereich des ersten Unterdruckbereichs für die gezielte Luftströmung im inneren der Vorrichtung maßgebend. Der erste Unterdruckbereich bzw. der Absaugventilator, der dem ersten Unterdruckbereich zugeordnet ist, dient dabei also zum einen der notwendigen Luftführung und zum anderen der ersten Separation von Leichtstoffen, Folien etc.It is advantageous for the suction of lighter material flow components that this together with the fluid flow in the calming zone of the second separation region downstream of a Fluidleitblechs or more Fluidleitbleche in their movement be slowed down and guided and are so easily separated by means of the first negative pressure range of the material flow. In this case, no or less turbulence occurs in the area of the stones and / or inert materials, so that no lightweight materials can flow back into the fraction or material group of the stones / inert materials / heavy parts. Also, the suction in the region of the first negative pressure range for the targeted air flow in the interior of the device is authoritative. The first negative pressure region or the exhaust fan, which is assigned to the first negative pressure region, thus serves, on the one hand, the necessary air guidance and, on the other hand, the first separation of lightweight materials, films, etc.

Der Begriff "Fluidwiderstand" bezieht sich auf die Neigung der einzelnen Materialgruppen, von einem Fluidstrom mitgerissen zu werden. Er wird vor allem vom Luftwiderstandsbeiwert und von der Dichte der Materialgruppen bzw. von deren Komponenten beeinflusst.The term "fluid resistance" refers to the tendency of the individual groups of materials to be entrained by a fluid stream. Above all, it is influenced by the coefficient of air resistance and the density of the material groups or their components.

In einem bevorzugten Ausführungsbeispiel ist denkbar, dass wenigstens ein zweites Förderband, wenigstens ein Fluidleitblech, ein zweiter Unterdruckbereich und insgesamt wenigstens vier Trennbereiche vorgesehen sind.In a preferred embodiment, it is conceivable that at least one second conveyor belt, at least one fluid guide plate, a second vacuum region and a total of at least four separation regions are provided.

Die insgesamt wenigstens vier Trennbereiche ermöglichen eine qualitativ bessere Trennung des Materialgemisches in die unterschiedlichen Materialgruppen. Wie im Folgenden noch erläutert wird, werden dabei unterschiedliche Trennmethoden so kombiniert, dass zum Erreichen des gewünschten Trennergebnisses ein möglichst geringer Aufwand notwendig ist.The total of at least four separation areas allow a better quality separation of the material mixture in the different material groups. As will be explained below, different separation methods are combined in such a way that the least possible effort is required to achieve the desired separation result.

Der Begriff "Fluidleitblech" bezeichnet hierbei einen Abschnitt der Vorrichtung zur gezielten Luftführung, der dazu ausgelegt ist, den Materialstrom und den Fluidstrom, welche beide die Vorrichtung durchströmen, zu lenken und dabei Verwirbelungen zu minimieren oder auszuschließen sowie Leichtstoffe u. Ä. davon abzuhalten, in die Fraktion bzw. Materialgruppe der Steine/Inertstoffe/Schwerteile zurückzuströmen.The term "Fluidleitblech" here refers to a portion of the device for targeted air guidance, which is designed to direct the flow of material and the fluid flow, both of which flow through the device, while minimizing turbulence or exclude and lightweight materials u. Ä. prevent it from flowing back into the fraction or material group of stones / inert materials / heavy parts.

So kann in einem bevorzugten Ausführungsbeispiel vorgesehen sein, dass in einem dritten Trennbereich die zweite und eine dritte Materialgruppe wenigstens teilweise mittels des Fluidleitblechs voneinander trennbar sind und auf dem zweiten Förderband wenigstens teilweise voneinander getrennt vorliegen.Thus, in a preferred embodiment it can be provided that in a third separation region, the second and a third material group are at least partially separable from each other by means of Fluidleitblechs and at least partially separated from each other on the second conveyor belt.

Während es sich bei der ersten Materialgruppe um Stoffe wie Steine, Inertstoffe oder Schwerteile mit dem geringsten Fluidwiderstand aller Materialgruppen des Materialgemisches handelt, ist die zweite Materialgruppe diejenige Materialgruppe mit dem größten Fluidwiderstand, die also am einfachsten mittels Unterdruckbereichen aus dem Materialstrom abtrennbar ist. Die dritte Materialgruppe, die unter anderem mittels des Fluidleitblechs von der zweiten Materialgruppe abtrennbar ist, kann auch aus Steinen, Inertstoffen oder Schwerteilen bestehen, jedoch können die Bestandteile der dritten Materialgruppe im Gegensatz zu den Bestandteilen der ersten Materialgruppe durchschnittlich kleiner sein und/oder ein von den Bestandteilen der ersten Materialgruppe verschiedenes fluiddynamisches Verhalten aufweisen, sodass sie mittels des vom Druckgebläse erzeugten Luftstroms von den Bestandteilen der ersten Materialgruppe abtrennbar sind und ferner mittels des Fluidleitblechs von den Bestandteilen der zweiten Materialgruppe abtrennbar sind. Das Fluidleitblech leitet dabei die Bestandteile von zweiter und dritter Materialgruppe auf unterschiedlichen Wegen auf das unterhalb des Fluidleitblechs vorgesehene zweite Förderband, sodass hierdurch eine dritte Trennung in einem dritten Trennbereich erfolgt. Dabei kann das Förderband als Austragungsband ausgebildet sein und zweite und dritte Materialgruppe können voneinander getrennt und horizontal aufeinander geschichtet, jedoch nicht aus dem Materialstrom entfernt, auf dem zweiten Förderband vorliegen. Dadurch sind zweite und dritte Materialgruppe wenigstens teilweise voneinander getrennt.While the first group of materials are substances such as stones, inert materials or heavy parts having the lowest fluid resistance of all material groups of the material mixture, the second material group is the material group with the greatest fluid resistance, which is thus most easily separable from the material flow by means of negative pressure regions. The third group of materials, which can be separated from the second material group, inter alia by means of the Fluidleitblechs can also consist of stones, inert materials or heavy parts, but the components of the third group of materials, in contrast to the components of the first group of materials may be on average smaller and / or one of the components of the first group of materials have different fluid dynamic behavior, so that they are separated by means of the air flow generated by the pressure fan from the constituents of the first group of materials and are further separated by the Fluidleitblechs of the components of the second group of materials. In this case, the fluid guide plate directs the components of the second and third material groups in different ways onto the second conveyor belt provided below the fluid guide plate, thereby resulting in a third separation in a third separation region. In this case, the conveyor belt can be designed as a discharge belt and second and third material group can be separated from each other and layered horizontally, but not removed from the flow of material, present on the second conveyor belt. As a result, the second and third material groups are at least partially separated from one another.

So kann also in einem bevorzugten Ausführungsbeispiel vorgesehen sein, dass die zweite Materialgruppe die Materialgruppe mit dem größten Fluidwiderstand aller Materialgruppen des Materialgemisches ist und z. B. Folien und/oder Folienteile umfasst, wobei die zweite Materialgruppe auf dem dem Fluidleitblech nachgelagerten zweiten Förderband größtenteils auf der dritten Materialgruppe aufliegt.Thus, it may be provided in a preferred embodiment that the second material group is the material group with the greatest fluid resistance of all material groups of the material mixture and z. B. films and / or film parts comprises, wherein the second group of materials rests largely on the third material group on the second conveyor belt downstream of the fluid guide plate.

Daraus ergibt sich eine für den Trennvorgang vorteilhafte Vortrennung der zweiten und dritten Materialgruppe, in der die leichteren bzw. die vom Fluidstrom einfacher mitreißbaren Bestandteile des Materialstroms, also z. B. Folien, Leichtstoffe und/oder Folienteile auf den darunter liegenden und mittels des Unterdruckbereichs schwerer absaugbaren Bestandteil der dritten Materialgruppe liegen. Die Steine, Inertstoffe oder sonstige Bestandteile der dritten Materialgruppe können also nicht auf den Folien und/oder Folienteilen aufliegen und diese nachteilig davon abhalten, vom Unterdruckbereich abgesaugt zu werden.This results in an advantageous for the separation process pre-separation of the second and third material group, in which the lighter or more easily entrained by the fluid flow components of the material flow, ie z. As foils, lightweight materials and / or film parts on the underlying and by means of the negative pressure area are difficult to suck part of the third group of materials. The stones, inert substances or other constituents of the third group of materials can therefore not rest on the films and / or film parts and adversely prevent them from being sucked from the vacuum region.

In einem weiteren bevorzugten Ausführungsbeispiel ist es denkbar, dass ein vierter Trennbereich den zweiten Unterdruckbereich umfasst, wobei ein noch im Materialstrom verbleibender Teil der zweiten Materialgruppe wenigstens teilweise mittels des zweiten Unterdruckbereichs in einer vertikalen Richtung von einer Hauptrichtung des Materialstroms abtrennbar ist.In a further preferred exemplary embodiment, it is conceivable for a fourth separation region to comprise the second negative pressure region, wherein a part of the second material group still remaining in the material flow can be at least partially separated from a main direction of the material flow by means of the second negative pressure region in a vertical direction.

Mittels des zweiten Unterdruckbereichs kann so vorteilhafterweise die zuvor mittels des Fluidleitblechs vorgenommene Vortrennung genutzt werden, um die nun freiliegenden Bestandteile der zweiten Materialgruppe, welche nicht vom ersten Unterdruckbereich abgetrennt worden sind, mittels des zweiten Unterdruckbereichs vom Materialstrom zu entfernen.By means of the second negative pressure region, the pre-separation previously carried out by means of the fluid guide plate can thus advantageously be used to remove the now exposed components of the second material group, which have not been separated from the first negative pressure region, from the material flow by means of the second negative pressure region.

In einem weiteren bevorzugten Ausführungsbeispiel ist dabei denkbar, dass die beiden Unterdruckbereiche mittels einer gemeinsamen Druckquelle oder mittels separater Druckquellen mit Unterdruck beaufschlagbar sind.In a further preferred embodiment, it is conceivable that the two negative-pressure regions can be subjected to negative pressure by means of a common pressure source or by means of separate pressure sources.

Eine einfach ausgeführte, gemeinsame Druckquelle, wie zum Beispiel ein Saugventilator, kann hierbei den Vorteil haben, dass die gesamte Vorrichtung einfacher und damit günstiger bereitstellbar ist. Andererseits sind Umstände denkbar, in denen der Betrieb mittels zweier separater Druckquellen vorteilhaft ist, da z. B. so insgesamt höhere Absaugleistungen an den beiden Unterdruckbereichen erbringbar sind oder es so möglich ist, ohne umständliche Druckluftleitungen von einer Druckquelle zu den beiden Unterdruckbereichen auszukommen.A simple running, common pressure source, such as a suction fan, this can have the advantage that the entire device is easier and thus cheaper to provide. On the other hand, circumstances are conceivable in which the operation by means of two separate pressure sources is advantageous because z. B. as a whole higher suction at the two negative pressure areas are achievable or it is possible to get along without cumbersome compressed air lines from a pressure source to the two vacuum areas.

Die Erfindung richtet sich ferner auf ein Verfahren zum Trennen eines Materialgemisches eines Materialstroms mittels einer Vorrichtung nach einem der Ansprüche 1 bis 6, umfassen die Schritte:

  • wenigstens teilweises Abtrennen einer ersten Materialgruppe mit dem geringsten Fluidwiderstand aller Materialgruppen des Materialgemisches vom Materialstrom in einem ersten Trennbereich;
  • erstes wenigstens teilweises Abtrennen einer zweiten Materialgruppe mittels eines ersten Unterdruckbereichs in einer horizontal seitlichen Richtung von einer Hauptrichtung des Materialstroms und von einer Beruhigungszone in einem zweiten Trennbereich;
  • wenigstens teilweises voneinander Trennen der zweiten und einer dritten Materialgruppe des Materialgemisches mittels eines Fluidleitblechs in einem dritten Trennbereich, wobei die zweite und die dritte Materialgruppe nicht mit der ersten Materialgruppe vermischt werden; und
  • zweites wenigstens teilweises Abtrennen von noch im Materialstrom verbleibenden Teilen der zweiten Materialgruppe mittels eines zweiten Unterdruckbereichs in einer vertikalen Richtung von einer Hauptrichtung des Materialstroms in einem vierten Trennbereich.
The invention further relates to a method for separating a material mixture of a material stream by means of a device according to one of claims 1 to 6, comprising the steps:
  • at least partially separating a first material group with the lowest fluid resistance of all material groups of the material mixture from the material flow in a first separation region;
  • first at least partially separating a second material group by means of a first negative pressure region in a horizontal lateral direction from a main direction of the material flow and from a settling zone in a second separating region;
  • at least partially separating the second and third material groups of the material mixture by means of a fluid guide plate in a third separation region, wherein the second and third material groups are not mixed with the first material group; and

Figur 1 zeigt dabei eine Prinzipskizze der erfindungsgemäßen Vorrichtung 1 zur Aufbereitung eines Materialgemisches. Hierbei wird das Materialgemisch zunächst über ein Aufnahmemittel 2 in die Vorrichtung 1 eingeführt und von dem Aufnahmemittel 2 auf ein erstes Förderband 3 geleitet. Das erste Förderband 3 fördert das Materialgemisch in eine Kammer 4, wobei das Materialgemisch mittels des ersten Förderbands 3 so in eine Richtung vertikal nach oben transportiert wird, dass das Materialgemisch innerhalb der Kammer 4 in Richtung des Kammerbodens 5 fallen kann. FIG. 1 shows a schematic diagram of the device 1 according to the invention for the preparation of a material mixture. Here, the material mixture is first introduced via a receiving means 2 in the device 1 and passed from the receiving means 2 to a first conveyor belt 3. The first conveyor belt 3 conveys the material mixture into a chamber 4, wherein the material mixture is transported by the first conveyor belt 3 in a direction vertically upward that the material mixture within the chamber 4 can fall in the direction of the chamber bottom 5.

Während der Fallbewegung des Materialgemisches wird das Materialgemisch vom Luftstrom eines Druckgebläses 6 erfasst, welcher von unten auf das in die Kammer 4 einfallende Materialgemisch gerichtet ist. Dabei werden Bestandteile des Materialgemisches entsprechend ihres Fluidwiderstands mehr oder weniger stark von dem Luftstrom erfasst und versetzt.During the fall movement of the material mixture, the material mixture is detected by the air flow of a pressure blower 6, which is directed from below onto the material mixture entering the chamber 4. In this case, components of the material mixture are detected more or less strongly by the air flow and offset according to their fluid resistance.

Im Bereich des Kammerbodens 5 sind zwei Auffangmittel versetzt entlang des Kammerbodens 5 angeordnet und durch einen am Kammerboden 5 angeordneten Trennscheitel 7 voneinander getrennt. Der Trennscheitel 7 erstreckt sich dabei vom Kammerboden 5 in etwa in Richtung der Kammeroberseite 8. Der Trennscheitel 7 definiert dabei einen ersten Trennbereich 30, in dem eine erste Materialgruppe, die zum Beispiel aus Steinen, Inertstoffen und/oder Schwerteilen bestehen kann, auf die beiden Auffangmittel aufgeteilt wird. Der Trennscheitel 7 ist hierfür verstellbar, sodass sowohl seine Länge als auch seine Winkelstellung, wie von den Pfeilen angedeutet, je nach Eigenschaften des Materialgemisches eingestellt werden können. Als erstes Auffangmittel ist dabei im gezeigten Ausführungsbeispiel ein Sammelbehälter 9 vorgesehen, der sich links vom Trennscheitel 7 und direkt unterhalb des rechten Endes des ersten Förderbands 3 befindet. Statt des Sammelbehälters 9 ist selbstverständlich auch ein Förderband, ein Queraustrageband oder eine sonstige Vorrichtung denkbar, die zum Auffangen oder Abscheiden von Materialbestandteilen geeignet ist. Als zweites Auffangmittel ist im gezeigten Ausführungsbeispiel ein zweites Förderband 10 rechts vom Trennscheitel 7 vorgesehen.In the region of the chamber bottom 5, two collecting means are arranged offset along the chamber bottom 5 and separated from one another by a separating vertex 7 arranged on the chamber bottom 5. The separating vertex 7 extends in this case from the chamber bottom 5 approximately in the direction of the chamber top 8. The separating vertex 7 defines a first separation region 30 in which a first group of materials, which may consist of stones, inert materials and / or heavy parts, for example Collecting means is divided. The separating vertex 7 is adjustable for this purpose, so that both its length and its angular position, as indicated by the arrows, can be adjusted depending on the properties of the material mixture. As the first collecting means in the illustrated embodiment, a collecting container 9 is provided, which is located to the left of the separating vertex 7 and directly below the right end of the first conveyor belt 3. Instead of the collecting container 9, of course, a conveyor belt, a Queraustrageband or other device is conceivable, which is suitable for collecting or separating material components. As a second collecting means, a second conveyor belt 10 is provided to the right of the separating vertex 7 in the illustrated embodiment.

Oberhalb des zweiten Förderbands 10 ist ein Fluidleitblech 11 vorgesehen, an dessen hinterer Seite und damit in dessen Windschatten eine Beruhigungszone 12 vorgesehen ist. Das Fluidleitblech 11 verhindert unter anderem, dass Leichtstoffe in die Steinfraktion bzw. den Sammelbehälter 9 fallen. Seitlich an die Beruhigungszone 12, d. h. senkrecht zur Eben der Figur 1, erstreckt sich ein erster, zweigeteilter Unterdruckbereich 13, mittels dem eine zweite Materialgruppe wenigstens teilweise in eine Richtung horizontal seitlich von der Hauptrichtung des Materialstroms 100 abgetrennt werden kann.Above the second conveyor belt 10, a fluid guide plate 11 is provided, on the rear side and thus in the slipstream a calming zone 12 is provided. Among other things, the fluid guide plate 11 prevents light substances from falling into the stone fraction or the collecting container 9. Laterally to the calming zone 12, ie perpendicular to the plane of the FIG. 1 , A first, two-part negative pressure region 13 extends, by means of which a second material group can be separated at least partially in a direction horizontally laterally from the main direction of the material flow 100.

Diejenigen Bestandteile des Materialstroms 100, die weder in den Sammelbehälter 9 fallen, noch mittels des ersten Unterdruckbereichs 13 abgetrennt worden sind, liegen auf dem zweiten Förderband 10 vor und sind dort auf Grund der Trennwirkung des Fluidleitblechs 11 und des Druckgebläses 6 übereinander getrennt geschichtet.Those constituents of the material stream 100 which neither fall into the collecting container 9 nor have been separated by means of the first negative pressure region 13 are present on the second conveyor belt 10 and are stacked one above the other there due to the separating action of the fluid guide plate 11 and the pressure blower 6.

So können die vom am zweiten Förderband 10 vorgesehenen zweiten Unterdruckbereich 14 erfassbaren Bestandteile des Materialstroms 100 abgesaugt werden, ohne dass die Absaugung dabei von auf leichteren Folienteilen liegenden schwereren Steinen oder ähnlichen Materialien behindert wird.Thus, the components of the material stream 100 which can be detected by the second vacuum region 14 provided on the second conveyor belt 10 can be sucked off, without the suction being hindered by heavier stones or similar materials lying on lighter parts of the film.

Die Unterdruckbereiche 13, 14 werden dabei im gezeigten Ausführungsbeispiel von separaten Druckquellen 15 mit Unterdruck beaufschlagt. Als Druckquellen 15 kommen zum Beispiel Absaugventilatoren in Frage. Denkbar ist jedoch auch eine Ausführungsform, in der eine gemeinsame Druckquelle 15 die beiden Unterdruckbereiche 13, 14 über entsprechende Druckleitungen mit Unterdruck beaufschlagt.The negative pressure regions 13, 14 are acted upon in the embodiment shown by separate pressure sources 15 with negative pressure. As pressure sources 15, for example, exhaust fans come into question. However, it is also conceivable one Embodiment in which a common pressure source 15, the two vacuum areas 13, 14 applied via corresponding pressure lines with negative pressure.

Die mittels der Unterdruckbereiche 13, 14 entfernten Bestandteile des Materialstroms 100 können natürlich ganz aus dem Materialstrom 100 entfernt und in eine andere Lager- oder Deponievorrichtung verbracht werden. Dies ist mit dem Pfeil "P" angedeutet.Of course, the components of the material stream 100 removed by means of the vacuum regions 13, 14 can be completely removed from the material stream 100 and transferred to another storage or landfill device. This is indicated by the arrow "P".

Im Bereich 20 bleiben schließlich all diejenigen Bestandteile des Materialstroms 100 übrig, welche weder von den Unterdruckbereichen 13, 14, noch vom ersten Trennbereich 30 mit Trennscheitel 7 abgetrennt worden sind. Die verbleibenden Bestandteile können ebenfalls in einem dafür vorgesehenen Bereich oder in einer dafür vorgesehenen Vorrichtung gelagert werden.Finally, all those components of the material stream 100 remain in region 20 which have not been separated from the vacuum regions 13, 14, nor from the first separation region 30 with separation peak 7. The remaining components may also be stored in a designated area or in a dedicated device.

Zum besseren Verständnis der Anordnung der einzelnen Trennbereiche 30, 40, 50, 60 zeigt Figur 2 eine ähnliche Darstellung des Steinabscheiders mit Windsichter wie Figur 1, allerding sind hierbei der Klarheit wegen lediglich die vier Trennbereiche 30, 40, 50, 60 und wenige weitere Komponenten aufgezeigt.For a better understanding of the arrangement of the individual separation regions 30, 40, 50, 60 shows FIG. 2 a similar representation of the stone separator with air classifier FIG. 1 However, for the sake of clarity, only the four separation areas 30, 40, 50, 60 and a few other components are shown here.

Im ersten Trennbereich 30 wird dabei der Materialstrom 100 seiner Hauptrichtung vom ersten Förderband 3 zum zweiten Förderband 10 folgend zunächst vom Druckgebläse 6 wie weiter oben beschrieben erfasst. Bestandteile des Materialstroms 100, die weniger gut vom Luftstrom des Druckgebläses 6 erfassbar sind, werden von dem Trennscheitel 7 zwischen Sammelbehälter 9 und zweitem Förderband 10 getrennt.In the first separation area 30, the material flow 100 of its main direction from the first conveyor belt 3 to the second conveyor belt 10 is first detected by the pressure fan 6 as described above. Components of the material flow 100, which are less easily detected by the air flow of the pressure blower 6, are separated from the separating vertex 7 between sump 9 and second conveyor belt 10.

Im zweiten Trennbereich 40 erfolgt eine weitere Trennung des Materialstroms 100. Diesmal werden mittels des Unterdruckbereichs 13 leichtere Bestandteile des Materialstroms 100 seitlich aus der Kammer 4 entfernt.In the second separation region 40, a further separation of the material flow 100 takes place. This time, lighter components of the material flow 100 are laterally removed from the chamber 4 by means of the negative pressure region 13.

Der dritte Trennbereich 50 umfasst das Fluidleitblech 11, mittels dem eine Trennung der zweiten und dritten Materialgruppe durchführbar ist, sodass diese auf dem zweiten Förderband 10 wenigstens teilweise voneinander getrennt vorliegen und im Rahmen der gezielten Luftführung nicht in den Bereich Steine/Inertstoffe/Schwerteile durch Verwirbelung gelangen.The third separation region 50 comprises the fluid guide plate 11, by means of which a separation of the second and third material group is feasible, so that they on the second conveyor belt 10 at least partially separated from each other and do not enter the area stones / inert materials / heavy parts by turbulence in the context of targeted air.

Der vierte und letzte Trennbereich 60 umfasst schließlich den zweiten Unterdruckbereich 14 und entfernt im Bereich des zweiten Förderbandes 10 die auf dem zweiten Förderband 10 oben aufliegenden verbleibenden leichten Bestandteile des Materialstroms 100.Finally, the fourth and last separation region 60 comprises the second negative pressure region 14 and removes in the region of the second conveyor belt 10 the remaining light components of the material stream 100 resting on the second conveyor belt 10 at the top.
