Description

Verfahren zum Trennen und/oder Sortieren von Schüttgütern Die Erfindung betrifft ein Verfahren zum Trennen und/oder Sortieren von Schüttgütern, insbesondere von zerkleinertem Schrott zur Rückgewinnung von wiederverwertbaren Wertstoffen. Weiter betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.Method for separating and/or sorting bulk materials The invention relates to a method for separating and/or sorting bulk materials, in particular crushed scrap, for the recovery of recyclable materials. The invention also relates to a device for carrying out the method.

Derartige Verfahren sind aus der Praxis in vielfältigen Ausgestaltungen bekannt, mit welchen bereits eine Vielzahl von Materialien näherungsweise quantitativ voneinander getrennt werden können. Gleichwohl verbleiben Mischungen von Schüttgütern, deren Trennung schwierig oder sogar unmöglich ist.Such methods are known from practice in a variety of configurations, with which a large number of materials can already be approximately quantitatively separated from one another. Nevertheless, mixtures of bulk materials remain which are difficult or even impossible to separate.

WO8704087 offenbart ein Verfahren und eine dementsprechende Vorrichtung zum Trennen von Schüttgütern mit einem Rechen am Abwurfrand einer vibrierenden Verteilerrinne. WO8704087 discloses a method and a corresponding device for separating bulk materials with a rake on the discharge edge of a vibrating distribution chute.

EP1990101 offenbart ein Verfahren und eine dementsprechende Vorrichtung zum Trennen von Schüttgütern mit einer Luftdüse am Abwurfrand einer vibrierenden Verteilerrinne. EP1990101 discloses a method and a corresponding device for separating bulk materials with an air nozzle on the discharge edge of a vibrating distribution chute.

Der Erfindung liegt daher die Aufgabe zu Grunde, ein Verfahren der eingangs genannten Art dahingehend zu verbessern, dass auch derartige Schüttgüter möglichst quantitativ voneinander in Gruppen von Schüttgutsorten getrennt werden können.The invention is therefore based on the object of improving a method of the type mentioned at the outset in such a way that such bulk materials can also be separated from one another as quantitatively as possible into groups of types of bulk material.

Gemäß der Erfindung gelingt dies durch ein Verfahren gemäß dem Anspruch 1, bei welchem zunächst das Schüttgut über einen Trichter, eine Schnecke, ein Förderband oder dergleichen auf eine Verteilerrinne aufgebracht wird, die mit einem Vibrationsantrieb zur flächigen Verteilung des Schüttgutes versehen ist, wodurch das Schüttgut zum Rand der Verteilerrinne wandert und von dort auf eine unterhalb angeordnete Separationsrinne fällt, die schräg angeordnet und ebenfalls mit einem Vibrationsantrieb versehen ist, wodurch eine Trennung des Schüttgutes in zwei Schüttgutsorten erfolgt, nämlich eine in der Separationsrinne aufwärts wandernde und eine abwärts wandernde, die jeweils am oberen bzw. unteren Rand der Separationsrinne getrennt aufgefangen werden können.According to the invention, this is achieved by a method according to claim 1, in which first the bulk material is applied via a hopper, a screw, a conveyor belt or the like to a distribution trough which is provided with a vibration drive for the surface distribution of the bulk material, whereby the bulk material migrates to the edge of the distribution chute and from there falls onto a separating chute arranged below, which is arranged at an angle and is also provided with a vibration drive, whereby the bulk material is separated into two types of bulk material, namely one migrating upwards in the separating chute and one migrating downwards, each can be collected separately at the top or bottom edge of the separation channel.

Der durch die Erfindung erreichte Vorteil besteht im wesentlichen darin, dass hierdurch auch Materialien voneinander trennbar sind, die bisher durch die bekannten Trennverfahren kaum separiert werden konnten. Von besonderem Vorteil ist hierbei, das bei einer Mischung aus Kupferkabel, Kupferlitzen, Kunststoffen, Leiterplatten, Eisen, Edelstahl, Steinen, Glas sowie NE-Metallen eine Trennung dahingehend möglich ist, dass die für eine Weiterverwertung interessanten Materialien, nämlich die Kupferkabel, Kupferlitzen, Kunststoffe und Leiterplatten, von den übrigen Materialien getrennt werden können.The advantage achieved by the invention consists essentially in the fact that it is also possible to separate materials from one another that previously could hardly be separated using the known separation methods. A particular advantage here is that a mixture of copper cables, copper strands, plastics, printed circuit boards, iron, stainless steel, stones, glass and non-ferrous metals can be separated in such a way that the materials that are of interest for further use, namely the copper cables, copper strands, Plastics and printed circuit boards, can be separated from the rest of the materials.

Die von dem Vibrationsantrieb der Separationsrinne erzeugten Schwingbewegungen erfolgen in der Ebene ihrer Auflagefläche .The oscillating movements generated by the vibrating drive of the separating channel take place in the plane of its bearing surface.

Dies fördert die Trennung des Schüttgutes in besonderer Weise.This promotes the separation of the bulk material in a special way.

Am Abwurfrand der Verteilerrinnen erfolgt eine Vorsortierung mit Hilfe eines Rechens. Die einer Wertstoffverwertung zuzuführenden Schüttgutanteile werden hierbei länger auf dem Rechen befördert, während die unerwünschten Beimengungen durch die Zwischenräume des Rechens fallen.At the discharge edge of the distribution chutes, a pre-sorting is carried out with the help of a rake. The bulk material that is to be recycled is transported longer on the rake, while the undesired admixtures fall through the gaps in the rake.

Unterhalb des Abwurfrandes erfolgt eine weitere Vorsortierung mit Hilfe einer die Schüttgutsorten separierenden Luftströmung mittels einer ersten Luftdüse Da die zu separierenden Teile bevorzugt einen erhöhten Luftwiderstand, bezogen auf Ihr Gewicht, aufweisen, erfolgt durch diese Luftströmung bereits eine Vortrennung.Below the discharge edge, further pre-sorting takes place with the help of an air flow separating the bulk material types using a first air nozzle. Since the parts to be separated preferably have an increased air resistance in relation to their weight, this air flow already pre-separates them.

In vergleichbarer Weise wird zur Unterstützung des Trennvorgangs auf der Separationsrinne oberhalb dieser eine Luftströmung mittels einer zweiten Luftdüse erzeugt, da die an sich im Trennprozess auf der Separationsrinne aufwärts sich bewegenden Schüttgutsorten zunächst dazu neigen, abwärts zu rollen.In a comparable way, to support the separating process on the separating chute, an air flow is generated above it by means of a second air nozzle, since the types of bulk material moving upwards in the separating process on the separating chute initially tend to roll down.

In vorrichtungsmäßiger Hinsicht ist die Erfindung gekennzeichnet durch eine Vorrichtung zum Trennen und/oder Sortieren von Schüttgütern gemäß dem Gegenstand des Anspruch 3 insbesondere von zerkleinertem Schrott zur Rückgewinnung von wiederverwertbaren Wertstoffen, die zunächst aus einer Verteilerrinne besteht, auf die das Schüttgut über einen Trichter, eine Schnecke, ein Förderband oder dergleichen aufgebracht wird, wobei die Verteilerrinne mit einem Vibrationsantrieb zur flächigen Verteilung des Schüttgutes versehen ist, ferner mit einer unterhalb davon angeordneten, das vom Rand der Verteilerrinne herabfallende Schüttgut aufnehmenden Separationsrinne, die schräg angeordnet und ebenfalls mit einem Vibrationsantrieb zur Trennung des Schüttgutes in zwei Schüttgutsorten versehen ist, sowie mit Auffangbehältnissen für die beiden am oberen bzw. unteren Rand der Separationsrinne anfallenden Schüttgutsorten.In terms of apparatus, the invention characterized by a device for separating and/or sorting bulk materials according to the subject matter of claim 3, in particular crushed scrap for the recovery of reusable ones recyclable materials, which initially consists of a distribution trough onto which the bulk material is applied via a hopper, a screw, a conveyor belt or the like, with the distribution trough being provided with a vibrating drive for the surface distribution of the bulk material, and also with a vibrating drive arranged below it, which is Edge of the distribution channel falling bulk material receiving separating channel, which is arranged at an angle and also provided with a vibration drive for separating the bulk material into two types of bulk material, as well as with collecting containers for the two types of bulk material occurring at the upper and lower edge of the separating channel.

Bei einer derartigen Vorrichtung hat es sich als vorteilhaft erwiesen, wenn die Neigung der Separationsrinne im Bereich zwischen 10° und 18° liegt, da hier die Trennergebnisse besonders optimal sind.With such a device, it has proven to be advantageous if the inclination of the separating channel is in the range between 10° and 18°, since the separating results are particularly optimal here.

Der Vibrationsantrieb der Separationsrinne ist unterhalb dieser angeordnet und erzeugt Schwingbewegungen in der Ebene ihrer Auflagefläche. Hierbei hat es sich als zweckmäßig erwiesen, wenn der Vibrationshub des Vibrationsantriebs der Separationsrinne im Bereich bis maximal 1,9 mm beträgt.The vibrating drive of the separating channel is arranged below it and generates oscillating movements in the plane of its bearing surface. In this connection, it has proven to be expedient if the vibration stroke of the vibration drive of the separating channel is in the range of up to a maximum of 1.9 mm.

Hierbei ist es weiter von besonderem Vorteil, wenn der Vibrationsantrieb der Separationsrinne elektromagnetisch ausgebildet ist.It is also of particular advantage here if the vibration drive of the separating channel is designed to be electromagnetic.

Um eine Vorsortierung des Schüttgutes zu erreichen, bevor dieses auf die Separationsrinne fällt, ist im Rahmen der Erfindung vorgesehen, das am Abwurfrand der Verteilerrinne ein Rechen angeordnet ist. Dieser führt zu einer ersten räumlichen Trennung des Schüttgutes. Bei den üblicherweise zur Anwendung kommenden Materialgrößen des Schüttgutes ist es zweckmäßig, wenn hierbei die lichte Rechenweite im Bereich zwischen 10 und 15 mm liegt.In order to achieve a pre-sorting of the bulk material before it falls onto the separating chute, the invention provides that at the discharge edge of the distribution chute a rake is arranged. This leads to a first spatial separation of the bulk material. With the material sizes of the bulk material that are usually used, it is expedient if the clear calculation width is in the range between 10 and 15 mm.

Weiter hat es sich hierbei als vorteilhaft erwiesen, wenn der Rechen zu seinem freien Ende abwärts unter einem Winkel von etwa 10° geneigt ist.It has also proven to be advantageous if the free end of the rake is inclined downwards at an angle of about 10°.

Um eine weitere Vortrennung zu erreichen, ist unterhalb des Abwurfrandes eine im wesentlichen horizontal ausgerichtete Luftdüse angeordnet, durch deren Luftströmung eine weitere Vorsortierung des Schüttgutes erfolgt.In order to achieve further pre-separation, a substantially horizontally aligned air nozzle is arranged below the discharge edge, the air flow from which further pre-sorting of the bulk material takes place.

Schließlich ist es in diesem Sinne zusätzlich von Vorteil, wenn oberhalb der Separationsrinne eine zweite Luftdüse angeordnet ist, deren Luftströmung zur weiteren Unterstützung des Trennvorgangs dient.Finally, in this sense, it is additionally advantageous if a second air nozzle is arranged above the separating channel, the air flow of which serves to further support the separating process.

Im folgenden wird die Erfindung an einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert; es zeigen:

In the following the invention is explained in more detail using an embodiment shown in the drawing; show it:
1
a perspective view of the device according to the invention,
2
a schematic side view of the device according to FIG 1 .

Die in der Zeichnung dargestellte Vorrichtung dient zum Trennen und/oder Sortieren von Schüttgütern, insbesondere von zerkleinertem Schrott zur Rückgewinnung von wiederverwertbaren Wertstoffen.The device shown in the drawing is used for separating and/or sorting bulk materials, in particular shredded scrap, for the recovery of recyclable materials.

Im einzelnen besteht diese Vorrichtung aus einer Verteilerrinne 1, auf die das Schüttgut über einen in der Zeichnung nicht näher dargestellten Trichter, eine Schnecke, ein Vorderband oder dergleichen aufgebracht wird. Die Verteilerrinne 1 ist hierbei mit einem Vibrationsantrieb 2 versehen, der für eine flächige Verteilung des Schüttgutes sorgt und dieses im Übrigen zu ihrem freien Rand 3 hin transportiert.Specifically, this device consists of a distribution channel 1, to which the bulk material is applied via a hopper, not shown in the drawing, a screw, a front belt or the like. The distributor channel 1 is provided with a vibration drive 2 which ensures that the bulk material is distributed over a large area and also transports it to its free edge 3 .

Ferner weist die Vorrichtung eine unterhalb der Verteilerrinne 1 angeordnete Separationsrinne 4 auf, die das vom freien Rand 3 der Verteilerrinne 1 herabfallende Schüttgut aufnimmt. Diese Separationsrinne 4 ist schräg angeordnet und ebenfalls mit einem Vibrationsantrieb 5 versehen, wodurch insbesondere wegen der Schrägstellung eine Trennung des Schüttgutes in zwei Schüttgutsorten möglich ist. Somit befinden sich an beiden Enden der Separationsrinne 4 Auffangbehältnisse, die die separierten Schüttgutsorten aufnehmen.Furthermore, the device has a separating channel 4 which is arranged below the distribution channel 1 and which receives the bulk material falling from the free edge 3 of the distribution channel 1 . This separating channel 4 is arranged at an angle and is also provided with a vibrating drive 5, which allows the bulk material to be separated into two types of bulk material, in particular because of the inclined position. Thus, at both ends of the separating chute 4 there are collecting containers that receive the separated types of bulk material.

Die eben beschriebene Anordnung erlaubt insbesondere eine Abtrennung von Kupferkabel, Kupferlitzen, Kunststoffe und Leiterplatten, also Wertstoffen von den im Übrigen im Schüttgut mit enthaltenen Steinen, Glas, Eisen und Edelstahl.The arrangement just described allows, in particular, a separation of copper cables, copper strands, plastics and printed circuit boards, ie recyclable materials, from the stones, glass, iron and stainless steel otherwise contained in the bulk material.

Hierbei zeigt sich, dass eine Trennung insbesondere dann sehr erfolgreich ist, wenn die Neigung der Separationsrinne 4 im Bereich zwischen 10° und 18° liegt.This shows that a separation is particularly successful when the inclination of the separating channel 4 is in the range between 10° and 18°.

Wie sich aus der Zeichnung ersehen lässt, ist der Vibrationsantrieb 5 der Separationsrinne 4 unterhalb dieser angeordnet und erzeugt Schwingbewegungen, die in der Ebene der Auflagefläche liegen. Um eine optimale Trennung zu erreichen, hat sich gezeigt, dass ein Vibrationshub des Vibrationsantriebs 5 der Separationsrinne 4 von maximal 1,9 mm ausreichend ist. Entscheidend ist jedoch, dass der Vibrationsantrieb 5 der Separationsrinne 4 elektromagnetisch ausgebildet ist.As can be seen from the drawing, the vibration drive 5 of the separating channel 4 is arranged below it and generates oscillating movements that lie in the plane of the support surface. In order to achieve an optimal separation, it has been shown that a vibration stroke of the vibration drive 5 of the separating channel 4 of a maximum of 1.9 mm is sufficient. What is decisive, however, is that the vibration drive 5 of the separating channel 4 is designed to be electromagnetic.

Wie weiter in der Zeichnung angedeutet ist, befindet sich am Abwurfrand 3 der Verteilerrinne 1 ein Rechen 6, der eine Vorsortierung des Schüttgutes vornimmt. Insbesondere Kabel und Litzen verharren länger auf dem Rechen 6 als das so genannte kubische Material, also Steine und Glas. Bei dem üblicherweise zur Trennung kommenden Schüttgut hat sich eine Rechenweite im Bereich zwischen 10 und 15 mm als zweckmäßig erwiesen. Günstig ist hierbei weiterhin, wenn der Rechen 6 zu seinem freien Ende hin abwärts unter einem Winkel von etwa 10° geneigt ist.As further indicated in the drawing, there is a rake 6 on the discharge edge 3 of the distribution channel 1, which carries out a pre-sorting of the bulk material. Cables and strands in particular remain longer on the rake 6 than the so-called cubic material, ie stones and glass. In the case of the bulk material that is usually separated, a rake width in the range between 10 and 15 mm has proven to be expedient. It is also favorable here if the rake 6 is inclined downwards at an angle of approximately 10° towards its free end.

Um den Trennprozess weiter zu optimieren, sind an der Vorrichtung zwei Luftdüsen 7,8 angeordnet, deren Luftströmung eine Vorsortierung vornimmt. Die erste Luftdüse 7 ist unterhalb des Abwurfrandes 3 angeordnet und sorgt dafür, dass das leichtere Material, das im weiteren Trennprozess auf der Separationsrinne 4 aufwärts wandert, bereits in diese Vorzugsrichtung bewegt wird. Die zweite Luftdüse 8 ist knapp oberhalb der Separationsrinne 4 angeordnet und befördert ebenfalls diejenigen Materialien, die auf der Separationsrinne 4 an sich eine Aufwärtsbewegung ausführen, in diese Vorzugsrichtung, da sie nach dem Aüftreffen auf der Separationsrinne 4 zunächst dazu neigen, abwärts zu rollen.In order to further optimize the separation process, two air nozzles 7, 8 are arranged on the device, the air flow of which carries out a pre-sorting. The first air nozzle 7 is arranged below the discharge edge 3 and ensures that the lighter material, which migrates upwards on the separating channel 4 in the further separation process, is already moved in this preferred direction. The second air nozzle 8 is just above the separation channel 4 arranged and also conveys those materials that perform an upward movement on the separating chute 4 in this preferred direction, since after hitting the separating chute 4 they initially tend to roll down.
