Description

Die Erfindung betrifft eine Austragsvorrichtung mit einem Gehäuse, in das ein Austragsrohr einer Schweltrommel einmündet und von dem ein Reststoffaustragsschacht ausgeht, der in eine Fördereinrichtung mündet, die an einem Auslaß endet, wobei am Reststoffaustragsschacht ein Füllstandsmesser angeordnet ist.The invention relates to a discharge device with a housing, into which a discharge pipe of a smoldering drum opens and from which a residue discharge chute emanates, which goes into a Conveyor opens, which ends at an outlet, on A fill level meter is arranged in the residue discharge shaft.

Eine derartige Austragsvorrichtung ist aus der DE 30 05 205 A1 bekannt. Die dort gezeigte Austragsvorrichtung für eine Pyrolyseanlage zeichnet sich dadurch aus, daß ein Austragsbehälter im Betrieb stets mit Schwelreststoff gefüllt ist, um einen gasdichten Verschluß zu bilden Ein Füllstandsmesser überwacht den Füllstand im Behälter. Am Ausgang des Behälters wird der Schwelreststoff durch eine Fördereinrichtung abtransportiert und zu einem Auslaß gebracht. Mit der Fördereinrichtung wird stets nur soviel Reststoff abtransportiert, daß der Füllstand im Gehäuse nicht unter die Position des Füllstandsmessers absinkt.Such a discharge device is from the DE 30 05 205 A1 known. The discharge device shown there for a pyrolysis plant is characterized in that a discharge container is always filled with smoldering residue during operation is to form a gastight seal A level meter monitors the level in the tank. At the exit of the container is the smoldering residue by a conveyor removed and brought to an outlet. With only as much residual material is removed from the conveyor that the level in the housing is not below the Position of the level meter drops.

Eine Trennung des Reststoffes in feine und grobe Bestandteile ist beim Bekannten nicht vorgesehen.A separation of the residual material into fine and coarse components is not intended for the acquaintance.

Eine solche Trennvorrichtung ist aus der EP 0086 488 A3 bekannt. Dazu ist dort ein Stangensieb vorgesehen, dem ein Schwingungserreger zugeordnet ist. Der zu sortierende Schwelreststoff fällt auf dieses Stangensieb. Unterhalb des Stangensiebes befindet sich ein Auslaß für feinen Reststoff und am Ende des Stangensiebes ist ein Auslaß für groben Reststoff vorhanden.Such a separating device is known from EP 0086 488 A3. For this purpose, a bar screen is provided, the one Vibration exciter is assigned. The smoldering residue to be sorted falls on this bar screen. Below the bar screen there is an outlet for fine residue and at the end of the bar screen is an outlet for coarse residues available.

Da auf das Stangensieb ständig Reststoff fällt, ist der grobe Reststoff durch feinen Reststoff verschmutzt, wenn er den Auslaß für den groben Reststoff erreicht. Die Verweilzeit auf dem Stangensieb reicht nicht aus, um durch die Schwingungen des Stangensiebes den feinen Reststoff vom groben Reststoff abzuschütteln, weil ständig neuer feiner Reststoff auf den groben Reststoff herabfällt.Since residual material constantly falls on the bar screen, the coarse one is Residual material is contaminated by fine residual material if it is Rough residue outlet reached. The dwell time on the bar screen is not sufficient to pass through the vibrations of the bar screen the fine residue from the coarse residue to shake off, because new fine residue on the coarse residue falls.

Der Erfindung lag die Aufgabe zugrunde, eine Austragsvorrichtung, die einen gasdichten Verschluß aufweist, durch eine Trennvorrichtung zu ergänzen, die groben Reststoff und feinen Reststoff voneinander trennt und dabei den groben Reststoff von anhaftenden Partikeln des feinen Reststoffes säubert.The invention was based on the object of a discharge device, which has a gastight closure, by a Separating device to complement the coarse residue and fine Separates residue and thereby the coarse residue from adhering particles of the fine residue.

Die Aufgabe wird nach der Erfindung dadurch gelöst, daß die Fördereinrichtung einen profilierten Trennboden aufweist, an den am von der Mündung des Reststoffaustragsschachtes abgewandten Ende ein Stangensieb angeformt ist, daß der Fördereinrichtung ein Schwingungserreger zugeordnet ist und daß das Stangensieb eine Abgabeöffnung für feinen Reststoff überdeckt und an einem Auslaß für groben Reststoff endet.The object is achieved according to the invention in that the Conveying device has a profiled partition the one facing away from the mouth of the residue discharge chute End of a bar screen is formed that the conveyor a vibration exciter is assigned and that the Bar screen covers a discharge opening for fine residual material and ends at a coarse residue outlet.

Mit dieser Austragsvorrichtung wird der Vorteil erzielt, daß auf dem Trennboden, der durch den Schwingungserreger in Schwingungen versetzt wird, der feine Reststoff vom groben Reststoff abgeschüttelt wird, ohne daß weiterer feiner Reststoff auf den groben Reststoff herabfallen könnte. Während der grobe Reststoff auf den erhöhten Stellen des Profiles aufliegt, sammelt sich der feine Reststoff in den Tälern des Profiles. Wenn der Reststoff das angeformte Stangensieb erreicht, ist der grobe Reststoff gereinigt. Der feine Reststoff fällt dann durch das Stangensieb in die Abgabeöffnung für feinen Reststoff und der gereinigte grobe Reststoff wird bedingt durch die Schwingung der Fördereinrichtung über das Stangensieb weiter transportiert und fällt in den Auslaß für groben Reststoff.With this discharge device, the advantage is achieved that on the partition that is caused by the vibration exciter Vibrations are set, the fine residue from the coarse Residual material is shaken off without further fine residual material could fall onto the coarse residue. While the coarse residue on the raised parts of the profile the fine residue collects in the valleys of the Profiles. When the residue reaches the molded bar screen, the coarse residue is cleaned. The fine residue then falls through the bar screen into the delivery opening for fine residue and the cleaned coarse residue due to the vibration of the conveyor over the The bar screen is transported further and falls into the outlet for coarse residue.

An die Abgabeöffnung bzw. an den Auslaß können weitere Vorrichtungen oder Behälter angeschlossen sein. Ein solcher Behälter braucht nicht gasdicht angebunden zu sein, da im Reststoffaustragsschacht stets eine Abdichtung durch Schwelreststoff gegeben ist.Additional devices can be attached to the discharge opening or to the outlet or container. Such a container does not need to be connected gas-tight, as in the waste material discharge shaft always a seal with smoldering residue given is.

Beispielsweise ist der Reststoffaustragsschacht vor seiner Mündung in die Fördereinrichtung in Richtung auf die Förderrichtung hin gebogen. Dadurch ist gewährleistet, daß der Reststoff stets vom Reststoffaustragsschacht auf die Fördereinrichtung gleitet.For example, the residue discharge chute is in front of it Mouth in the conveyor in the direction of the conveyor bent towards it. This ensures that the Residual material always from the residual material discharge shaft to the conveyor slides.

Beispielsweise ist der Reststoffaustragsschacht gegen die Fördereinrichtung durch einen flexiblen Kompensator abgedichtet. Dadurch ist eine Abdichtung zwischen diesen beiden Bauteilen gegeben, die den Bewegungen der Fördereinrichtung relativ zum Reststoffaustragsschacht standhält.For example, the residue discharge chute is against Conveyor sealed by a flexible compensator. This creates a seal between these two components given the movements of the conveyor relative to the residue discharge chute.

Der profilierte Trennboden besteht beispielsweise aus einem profilierten Blech oder aus einem profilierten Gußstück. Beispielsweise hat der Trennboden einen sägezahnartigen Querschnitt.The profiled partition consists, for example, of a profiled sheet or from a profiled casting. For example the partition has a sawtooth-like cross-section.

Am Übergang zum Stangensieb weist der Trennboden beispielsweise gebogene Ausnehmungen auf. Damit wird vorteilhafterweise verhindert, daß sich grober Reststoff, der Drahtgewölle umfassen kann, am Ende des Trennbodens verhakt.At the transition to the bar screen, the partition has, for example curved recesses. This is advantageous prevents coarse residue, the wire crust may include, hooked at the end of the partition.

Nach einem anderen Beispiel sind zwischen der Abgabeöffnung für feinen Reststoff und dem Auslaß für groben Reststoff kantenfreie Trennwände angeordnet. Auch damit wird der Vorteil erzielt, daß sich keine Drahtgewölle verhaken können.According to another example, there are between the discharge opening for fine residue and the outlet for coarse residue without edges Partitions arranged. This also becomes the advantage achieved that no wire piles can get caught.

Der Fördereinrichtung sind beispielsweise zwei getrennt steuerbare Schwingungserreger zugeordnet. Beispielsweise kann die Drehzahl der beiden Schwingungserreger unterschiedlich sein. The conveyor is, for example, two separately controllable Vibration exciter assigned. For example, the Speed of the two vibration exciters may be different.

Mit der Austragsvorrichtung nach der Erfindung wird auch der Vorteil erzielt, daß durch den Einsatz einer mit einem Schwingungserreger ausgestatteten Fordereinrichtung der Schwelreststoffpfropfen im Reststoffaustragsschacht verdichet wird, so daß ein Eintritt von Luftsauerstoff in die Schwelvorrichtung besser als bisher möglich verhindert wird. Insbesondere wird der Vorteil erzielt, daß grober Reststoff von feinem Reststoff deutlich besser als es früher möglich war getrennt wird.With the discharge device according to the invention, the Advantage achieved that by using one with one Vibration exciter equipped with the Smolder residue plug in the residue discharge chute compacted is so that an entry of atmospheric oxygen into the smoldering device prevented better than previously possible. Especially the advantage is achieved that coarse residue of fine residue much better than was previously possible is separated.

Die geschilderte Kombination aus profiliertem Trennboden und Stangensieb kann auch für die Trennung oder Reinigung anderer Stoffe eingesetzt werden.The described combination of profiled partition and Bar screen can also be used for separating or cleaning others Fabrics are used.

Die Austragsvorrichtung nach der Erfindung wird anhand der Zeichnung näher erläutert.

Figur 1 zeigt ein Gehäuse 1 einer Austragsvorrichtung in das ein Austragsrohr 2 einer Schweltrommel 3 einmündet, in der Müll verschwelt wird. Dabei entstehen Schwelgas und Schwelreststoff, die über das Austragsrohr 2 in das Gehäuse 1 gelangen. Das drehbare Austragsrohr 2 ist dazu über Dichtungen 4 vom Gehäuse 1 abgedichtet. Das Schwelgas verläßt das Gehäuse 1 über eine im oberen Teil angeordnete Abgabeöffnung 5, die gasdicht mit einer nicht gezeigten Vorrichtung zur Weiterbehandlung des Schwelgases, z.B. mit einer Hochtemperaturbrennkammer verbunden ist. Der feste Schwelreststoff fällt im Gehäuse 1 nach unten. Vom unteren Ausgang des Gehäuses 1, der durch einen Notschieber 6 verschlossen werden kann, geht ein Reststoffaustragsschacht 7 aus. Dieser mündet in eine Fördereinrichtung und weist kurz vor der Einmündung eine Biegung in Richtung auf die Transportrichtung der Fördereinrichtung auf. Am oberen Abschnitt des Reststoffaustragsschachtes 7 ist ein Füllstandsmesser 8 angeordnet. Die Fördereinrichtung wird so geregelt, daß im Reststoffaustragsschacht 7 stets eine dichte Schüttung von Schwelreststoff vorhanden ist, die ein Zurückströmen von Gasen, insbesondere von Luftsauerstoff, in die Schweltrommel 3 verhindert.Figure 1 shows a housing 1 of a discharge device in the a discharge pipe 2 of a smoldering drum 3 opens in the Garbage is garbage. This creates smoldering gas and smoldering residue, which get into the housing 1 via the discharge pipe 2. The rotatable discharge pipe 2 is for this purpose via seals 4 sealed by the housing 1. The carbonization gas leaves the housing 1 via a dispensing opening 5 arranged in the upper part, the gas-tight with a device for further treatment, not shown the carbonization gas, e.g. with a high temperature combustion chamber connected is. The solid smoldering residue falls in Housing 1 down. From the lower exit of the housing 1, the can be closed by an emergency slide 6, comes in Residual material discharge chute 7. This ends in a conveyor and has a bend just before the junction in the direction of the transport direction of the conveyor on. At the upper section of the residue discharge chute 7 a level meter 8 is arranged. The conveyor will regulated so that in the waste material discharge shaft 7 always one dense bed of smoldering residue is present, the one Backflow of gases, especially atmospheric oxygen, in the smoldering drum 3 prevented.

Die Fördereinrichtung besteht aus einem profilierten Trennboden 9, der sich in der Nähe der Mündung des Reststoffaustragsschachtes 7 befindet, und aus einem in Transportrichtung an den Trennboden 9 angeformten Stangensieb 10, sowie aus einem Schwingungserreger 11. Dieser kann Federn zur Lagerung der Fördereinrichtung und Exzenterrollen, die durch einen nicht gezeigten Motor angetrieben werden, umfassen. Der Reststoffaustragsschacht 7 ist gegen die Fördereinrichtung durch einen flexiblen Kompensator 12 abgedichtet. Der Schwingungserreger 11 kann steuerbar sein. Dadurch kann sichergestellt werden, daß der Reststoffaustragsschacht 7 stets durch den Reststoff gasdicht verschlossen ist. Durch die Schwingung der Fördereinrichtung werden auf dem Trennboden 9 grobe und feine Reststoffe voneinander getrennt und gleichzeitig fortbewegt. Die feinen Reststoffe fallen dann durch das Stangensieb 10 und gelangen in eine dort angeordnete Abgabeöffnung 13 für feinen Reststoff. Diese Abgabeöffnung 13 kann in einen Behälter, aber auch in eine Vorrichtung zur Weiterbehandlung, z.B. in eine Hochtemperaturbrennkammer münden. Der grobe Reststoff wird über das Stangensieb 10 bis zu seinem Ende transportiert, von wo er in einen dort angeordneten Auslaß 14 für groben Reststoff fällt. An diesen Auslaß 14 kann sich ein Container 15 anschließen. Zwischen der Abgabeöffnung 13 und dem Auslaß 14 sind kantenfreie Trennwände 16 angeordnet, an denen kein Reststoff hängen bleibt.The conveyor consists of a profiled partition 9, which is near the mouth of the residue discharge chute 7 is located, and from one in the transport direction rod screen 10 formed on the partition 9, and from a Vibration exciter 11. This can use springs for storage the conveyor and eccentric rollers by a Motor, not shown, are included. The residue discharge chute 7 is against the conveyor sealed a flexible compensator 12. The vibration exciter 11 can be controllable. This can ensure be that the residual material discharge shaft 7 always by the Residual material is sealed gas-tight. By the vibration of the Conveyor are 9 coarse and fine on the partition Residues separated from each other and moved at the same time. The fine residues then fall through the rod screen 10 and get into a discharge opening 13 arranged there fine residue. This discharge opening 13 can be placed in a container, but also in a device for further treatment, e.g. open into a high temperature combustion chamber. The rough residue is transported over the bar screen 10 to its end, from where he into an outlet 14 arranged there for coarse residue falls. At this outlet 14 can Connect container 15. Between the discharge opening 13 and edge-free partition walls 16 are arranged at the outlet 14 where no residue gets stuck.

Figur 2 zeigt einen Querschnitt durch einen Trennboden 9, der ein sägezahnförmiges Profil 9a aufweist. In den Tälern dieses Profiles 9a sammelt sich der feine Reststoff an, während der grobe Reststoff auf den Spitzen des Profiles 9a liegt. Durch die Schwingungsbewegung des Trennbodens 9 wird feiner Reststoff, der am groben Reststoff haftet, abgeschüttelt, so daß ein möglichst reiner grober Reststoff übrig bleibt.Figure 2 shows a cross section through a partition 9 has a sawtooth-shaped profile 9a. In the valleys this Profiles 9a accumulates the fine residual material during the coarse residue lies on the tips of the profile 9a. By the oscillating movement of the partition 9 becomes fine residue, which adheres to the coarse residue, shaken off, so that a coarse residue that is as pure as possible remains.

Figur 3 zeigt den Übergang des Trennbodens 9 zum Stangensieb 10. In diesem Übergangsbereich weist der Trennboden 9 gebogene Ausnehmungen 9b auf. Dadurch wird verhindert, daß grober Reststoff, z.B. Drahtgewölle, am Ende des Trennbodens 9 hängen bleibt.Figure 3 shows the transition of the partition 9 to the bar screen 10. In this transition area, the partition 9 has curved Recesses 9b. This prevents being coarser Residue, e.g. Wirewalls, hang at the end of the partition 9 remains.

Mit der Austragssvorrichtung nach der Erfindung wird einerseits ein Zurückströmen von Luftsauerstoff in die Schweltrommel 3 vermieden und andererseits wird der grobe Reststoff fast vollständig vom feinen Reststoff getrennt. Während der feine Reststoff in der Regel weiterbehandelt wird, besteht der grobe Reststoff aus Metall und Glasteilen, die direkt als Rohstoffe dienen können.With the discharge device according to the invention, on the one hand a backflow of atmospheric oxygen into the smoldering drum 3 avoided and on the other hand the coarse residue almost completely separated from the fine residue. During the fine residual material is usually treated the coarse residue from metal and glass parts that directly as Raw materials can serve.
