AustragsvorrichtungDischarge device
Die Erfindung betrifft eine Austragsvorrichtung mit einem Ge¬ häuse, in das em Austragsrohr einer Schweltrommel einmündet und von dem em Reststoffaustragsschacht ausgeht, der m eine Fördereinrichtung mündet, die an einem Auslaß endet, wobei am Reststoffaustragsschacht em Füllstandsmesser angeordnet ist.The invention relates to a discharge device with a housing into which a discharge tube of a smoldering drum opens and from which a residue discharge chute opens, which opens into a conveyor device that ends at an outlet, a level meter being arranged on the residue discharge shaft.
Eine derartige Austragsvorrichtung ist aus der DE 30 05 205 AI bekannt. Die dort gezeigte Austragsvorrich¬ tung für eine Pyrolyseanlage zeichnet sich dadurch aus, daß ein A^stragsbehalter im Betrieb stets mit Schwelreststoff ge- füllt ist, um einen gasdichten Verschluß zu bilden. Ein Füll¬ standsmesser überwacht den Füllstand im Behälter. Am Ausgang des Behalters wird der Schwelreststoff durch eine Forderein¬ richtung abtransportiert und zu einem Auslaß gebracht. Mit der Fordereinrichtung wird stets nur soviel Reststoff ab- transportiert, daß der Füllstand im Gehäuse nicht unter die Position deε Füllstandsmessers absinkt.Such a discharge device is known from DE 30 05 205 AI. The Austragsvorrich¬ shown there processing for a pyrolysis plant is characterized in that an A ^ is stragsbehalter always filled in operation with overall carbonization to form a gas tight seal. A level meter monitors the level in the container. At the outlet of the container, the smoldering residue is removed by a conveyor and brought to an outlet. With the conveying device, only so much residual material is transported away that the fill level in the housing does not drop below the position of the fill level meter.
Eine Trennung des Reststoffes m feine und grobe Bestandteile ist oeira Bekannten nicht vorgesehen.A separation of the residual material into fine and coarse components is not intended for oeira acquaintances.
Eine solche Trennvorrichtung ist aus der EP 0086 488 A3 be¬ kannt . Dazu ist dort ein Stangensieb vorgesehen, dem em Schwingungserreger zugeordnet ist. Der zu sortierende Schwel¬ reststoff fallt auf dieses Stangensieb. Unterhalb des Stan- gensiebes befindet sich em 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, which is assigned to the vibration exciter. The smoldering residue to be sorted falls on this rod screen. There is an outlet for fine residual material underneath the rod sieve and an outlet for coarse residual material is available at the end of the rod sieve.
Da auf das Stangensieb ständig Reststoff fallt, ist der grobe Reststoff durch feinen Reststoff verschmutzt, wenn er denSince residual material constantly falls onto the bar screen, the coarse residual material is contaminated by fine residual material when it is
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 standig neuer feiner Reststoff auf den groben Reststoff herabfallt.Rough residue outlet reached. The dwell time on the bar screen is not sufficient to get through the vibrations of the bar screen to shake off the fine residue from the coarse residue, because constantly new fine residue falls onto the coarse residue.
Der Erfindung lag die Aufgabe zugrunde, eine Austragsvorrich¬ tung, die einen gasdichten Verschluß aufweist, durch eine Trennvorrichtung zu erganzen, 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 supplementing a discharge device which has a gas-tight seal by a separating device which separates coarse residual material and fine residual material from one another and thereby cleans the coarse residual material from adhering particles of the fine residual material.
Die Aufgabe wird nach der Erfindung dadurch gelost, daß die Fordereinrichtung einen profilierten Trennboden aufweist, an den am von der Mundung des Reststoffaustragsschachtes abge¬ wandten Ende ein Stangensieb angeformt ist, daß der Forder- emrichtung em Schwmgungserreger zugeordnet ist und daß das Stangensieb eme Abgabeoffnung 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 separating bottom, to which a rod screen is formed at the end facing away from the mouth of the residue discharge chute, that the vibrating exciter is assigned to the conveying device and that the rod sieve has a discharge opening for covers fine residue and ends at an outlet for coarse residue.
Mit dieser Austragsvorrichtung wird der Vorteil erzielt, daß auf dem Trennboden, der durch den Schwingungserreger inWith this discharge device, the advantage is achieved that on the partition, which is caused by the vibration exciter in
Schwingungen versetzt wird, der feine Reststoff vom groben Reststoff abgeschüttelt wird, ohne daß weiterer feiner Rest¬ stoff auf den groben Reststoff herabfallen konnte. Wahrend 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 er¬ reicht, ist der grobe Reststoff gereinigt. Der feine Rest¬ stoff fällt dann durch das Stangensieb in die Abgabeoffnung für feinen Reststoff und der gereinigte grobe Reststoff wird bedingt durch die Schwingung der Fordereinrichtung über das Stangensieb weiter transportiert und fällt in den Auslaß für groben Reststoff.Vibrations are added, the fine residue is shaken from the coarse residue without further fine residue could fall onto the coarse residue. While the coarse residue rests on the elevated areas of the profile, the fine residue collects in the valleys of the profile. When the residual material reaches the molded rod sieve, the coarse residual material is cleaned. The fine residue then falls through the bar screen into the discharge opening for fine residue and the cleaned coarse residue is transported further via the bar screen due to the oscillation of the conveying device and falls into the outlet for coarse residue.
An die Abgabeoffnung bzw. an den Auslaß können weitere Vor- richtungen oder Behalter angeschlossen sein. Em solcher Be¬ hälter braucht nicht gasdicht angebunden zu sein, da im Rest- stoffaustragsschacht stets eine Abdichtung durch Schwelrest- stoff gegeben ist.Further devices or containers can be connected to the delivery opening or to the outlet. Such a container does not need to be gas-tight, since in the rest of the container material discharge shaft is always sealed by smoldering residue.
Beispielsweise ist der Reststoffaustragsschacht vor seiner Mündung m die Fordereinrichtung in Richtung auf die Forder¬ richtung hin gebogen. Dadurch ist gewährleistet, daß der Reststoff stets vom Reststoffaustragsschacht auf die För¬ dereinrichtung gleitet.For example, the residue discharge chute is bent in front of its mouth in the conveying device in the direction of the conveying direction. This ensures that the residual material always slides from the residual material discharge shaft onto the conveying device.
Beispielsweise ist der Reststoffaustragsschacht gegen dieFor example, the residue discharge chute is against
Fordereinrichtung durch einen flexiblen Kompensator abgedich¬ tet. Dadurch ist eme Abdichtung zwischen diesen beiden Bau¬ teilen gegeben, die den Bewegungen der Fordereinrichtung re¬ lativ zum Reststoffaustragsschacht standhält.Conveying device sealed by a flexible compensator. This provides a seal between these two components, which withstands the movements of the conveying device relative to the waste material discharge shaft.
Der profilierte Trennboden besteht beispielsweise aus einem profilierten Blech oder aus einem profilierten Gußstück. Bei¬ spielsweise hat der Trennboden einen sagezahnartigen Quer¬ schnitt .The profiled partition consists for example of a profiled sheet or a profiled casting. For example, the dividing floor has a sawtooth-like cross section.
Am Obergang zum Stangensieb weist der Trennboden beispiels¬ weise gebogene Ausnehmungen auf. Damit wird vorteilhafter¬ weise verhindert, daß sich grober Reststoff, der Drahtgewölle umfassen kann, am Ende des Trennbodens verhakt.At the transition to the bar screen, the dividing floor has, for example, curved recesses. This advantageously prevents coarse residues, which may include wire piles, from getting caught at the end of the partition.
Nach einem anderen Beispiel εind zwischen der Abgabeöffnung für feinen Reststoff und dem Auslaß für groben Reststoff kan¬ tenfreie Trennwände angeordnet. Auch damit wird der Vorteil erzielt, daß sich keine Drahtgewölle verhaken können.According to another example, edge-free partitions are arranged between the discharge opening for fine residue and the outlet for coarse residue. This also has the advantage that no wire bulges can get caught.
Der Fordereinrichtung sind beispielweise zwei getrennt εteu- erbare Schwingur.gserreger zugeordnet. Beispielsweiεe kann die Drehzahl der beiden Schwingungserreger unterschiedlich sein. Mit der Austragsvorrichtung nach der Erfindung wird auch der Vorteil erzielt, daß durch den Einsatz einer mit einem Schwingungserreger ausgestatteten Fördereinrichtung der Schwelreststoffpfropfen im Reststoffaustragsschacht verdichet wird, so daß ein Eintritt von Luftsauerstoff in die Schwel¬ vorrichtung besser als bisher möglich verhindert wird. Insbe¬ sondere wird der Vorteil erzielt, daß grober Restεtoff von feinem Reststoff deutlich besser als es früher möglich war getrennt wird.For example, two separately controllable vibratory exciters are assigned to the delivery device. For example, the speed of the two vibration exciters can be different. With the discharge device according to the invention, the advantage is also achieved that the use of a conveyor equipped with a vibration exciter compresses the sulfur residue plug in the residue discharge shaft, so that an entry of atmospheric oxygen into the sulfurization device is prevented better than previously possible. In particular, the advantage is achieved that coarse residue is separated from fine residue much better than was previously possible.
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 the separation or cleaning of other materials.
Die Austragεvorrichtung nach der Erfindung wird anhand der Zeichnung näher erläutert.The discharge device according to the invention is explained in more detail with reference to the drawing.

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 Schwel¬ reststoff, die über daε Austragsrohr 2 in das Gehäuse 1 ge- langen. Das drehbare Austragsrohr 2 ist dazu über Dichtungen 4 vom Gehäuse 1 abgedichtet. Das Schwelgas verläßt das Ge¬ häuse 1 über eine im oberen Teil angeordnete Abgabeöffnung 5, die gasdicht mit einer nicht gezeigten Vorrichtung zur Wei¬ terbehandlung des Schwelgases, z.B. -r.it einer Hochtemperatur- brennkammer 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 em Reststoffaustragsschacht 7 aus. Dieser mündet in eine För- deremrichtung 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 Zurückstromen von Gasen, inεbesondere von Luftsauerstoff, m die Schweltrommel 3 verhindert.FIG. 1 shows a housing 1 of a discharge device into which a discharge tube 2 of a smoldering drum 3 opens, in which waste is carbonized. This produces carbonization gas and carbonization residue, which reach the housing 1 via the discharge tube 2. For this purpose, the rotatable discharge pipe 2 is sealed off from the housing 1 via seals 4. The carbonization gas leaves the housing 1 via a dispensing opening 5 arranged in the upper part, which is gas-tight with a device, not shown, for further treatment of the carbonization gas, for example with a high temperature combustion chamber is connected. The solid smoldering residue falls down in the housing 1. From the lower outlet of the housing 1, which can be closed by an emergency slide 6, em residue discharge chute 7 starts. This opens into a conveyor device and has a bend shortly before the junction in the direction of the transport direction of the conveyor device. A fill level meter 8 is arranged on the upper section of the residue discharge chute 7. The conveyor is regulated so that there is always a dense bed of smoldering residue in the residue discharge chute 7, which prevents the backflow of gases, in particular atmospheric oxygen, from the smoldering drum 3.
Die Fordereinrichtung besteht aus einem profilierten Trennbo- den 9, der sich m der Nähe der Mündung des Reststoffaus¬ tragsschachtes 7 befindet, und aus einem in Transportrichtung an den Trennboden 9 angeformten Stangensieb 10, sowie aus ei¬ nem Schwingungserreger 11. Dieser kann Federn zur Lagerung der Fördereinrichtung und Exzenterrollen, die durch einen nicht gezeigten Motor angetrieben werden, umfassen. Der Rest¬ stoffaustragsschacht 7 ist gegen die Fördereinrichtung durch einen flexiblen Kompensator 12 abgedichtet. Der Schwingungε- erreger 11 kann steuerbar sein. Dadurch kann sichergestellt werden, daß der Reststoffaustragsschacht 7 stets durch den Reεtεtoff gaεdicht 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 Reεtεtoff. Dieεe Abgabeöffnung 13 kann in einen Behäl¬ ter, aber auch in eine Vorrichtung zur Weiterbehandlung, z.B. in eme Hochtemperaturbrennkammer münden. Der grobe Reεtεtoff wird über das Stangensieb 10 bis zu seinem Ende transpor¬ tiert, 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 conveying device consists of a profiled separating floor 9, which is located in the vicinity of the mouth of the residual material discharge chute 7, and of a rod screen 10 formed on the separating floor 9 in the transport direction, and of a vibration exciter 11. This can provide springs for Storage of the conveyor and eccentric rollers, which are driven by a motor, not shown, include. The residue discharge chute 7 is sealed against the conveyor by a flexible compensator 12. The vibration exciter 11 can be controllable. This can ensure that the residue discharge chute 7 is always sealed gas-tight by the residual material. The vibration of the conveyor means that coarse and fine residues are separated from one another on the separating tray 9 and simultaneously moved. The fine residues then fall through the rod sieve 10 and reach a discharge opening 13 arranged there for fine residues. This discharge opening 13 can open into a container, but also into a device for further treatment, for example in a high-temperature combustion chamber. The coarse residual material is transported over the bar screen 10 to its end, from where it passes into an outlet 14 arranged there coarse residue falls. A container 15 can connect to this outlet 14. Edge-free partition walls 16 are arranged between the discharge opening 13 and the outlet 14, on which no residue remains.
Figur 2 zeigt einen Querschnitt durch einen Trennboden 9, der em sägezahnformiges 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 Rest- stoff, der am groben Reststoff haftet, abgeschüttelt, so daß em möglichst reiner grober Reststoff übrig bleibt.Figure 2 shows a cross section through a partition 9, which has a sawtooth-shaped profile 9a. The fine residual material accumulates in the valleys of this profile 9a, while the coarse residual material lies on the tips of the profile 9a. The oscillating movement of the separating base 9 shakes off fine residual material which adheres to the coarse residual material, so that a coarse residual material remains as pure as possible.
Figur 3 zeigt den Übergang des Trennbodens 9 zum Stangensieb 10. In diesem Ubergangsbereich weist der Trennboden 9 gebo¬ gene Ausnehmungen 9b auf. Dadurch wird verhindert, daß grober Reststoff, z.B. Drahtgewolle, am Ende des Trennbodens 9 hän¬ gen bleibt.FIG. 3 shows the transition from the dividing plate 9 to the rod screen 10. In this transition area, the dividing plate 9 has curved recesses 9b. This prevents coarse residue, e.g. Wire wool, remains hanging at the end of the partition 9.
Mit der Austragssvorπchtung nach der Erfindung wird einer¬ seits em Zurückstromen von Luftsauerstoff m die Schweltrom¬ mel 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, backflow of atmospheric oxygen is avoided, and on the other hand, the coarse residue is almost completely separated from the fine residue. While the fine residue is usually treated further, the coarse residue consists of metal and glass parts that can be used directly as raw materials.
