Abstract

The crematorium oven has support rollers (23) forming a grid on which the coffin is placed. The rollers are rotated to agitate the ashes to break them up and to shake residual bones into a collecting duct for further processing. The whole process is with the oven door closed. The rollers are located through the walls of the oven and through the outer cooling jacket. Each roller can be fitted with a separate electric motor to generate an improved shaking effect. Each roller is covered with a heat resistant sleeve.

Description

Vorrichtung zum Tragen eines Sarges innerhalb eines Hauptbrennraums eines Einäscherungsofens durch einen Rost.Device for carrying a coffin through a grate within a main combustion chamber of a cremation furnace.

Bekannte Einäscherungsöfen verfügen über einen Rost aus mehreren, in Längsrichtung des Sarges gesehen, hintereinanderliegenden querverlaufenden Streben. Der Abstand zwischen zwei Streben beträgt üblicherweise 300 mm. Auf diesem, einen Hauptbrennraum des Einäscherungsofens abschließenden Rost, wird der Sarg mit der zu verbrennenden Leiche abgesetzt. Der Verbrennungsvorgang kann nun beginnen. Der Sarg ist dabei so ausgelegt, daß zunächst der Sargdeckel durchbrennt. Anschließend verdampft das Leichenwasser, und die Leiche wird sodann mit der unteren Wanne des Sarges verbrannt.Known cremation ovens have a grate consisting of several transverse struts, one after the other, seen in the longitudinal direction of the coffin. The distance between two struts is usually 300 mm. The coffin with the body to be cremated is placed on this grate, which closes off a main combustion chamber of the cremation furnace. The combustion process can now begin. The coffin is designed so that the coffin lid burns through first. The body water then evaporates, and the body is then burned with the lower pan of the coffin.

Oft werden Knochen des Leichnams nur unvollständig verbrannt. Diese liegen auf dem Rost auf und können bei ungünstiger Lage nicht durch den Rost hindurchfallen. Es ist daher erforderlich, manuell die Sargeinfuhrtür des Hauptbrennraums zu öffnen und mit einem Schürhaken zum einen den Verbrennungsvorgang zu fördern und zum anderen Knochen so zu stellen, daß sie durch den Rost fallen können. Problematisch in dieser Beziehung sind vor allem Unter- und Oberarmknochen sowie Ober- und Unterschenkelknochen.Bones of the body are often only incompletely burned. These rest on the grate and cannot fall through the grate in an unfavorable position. It is therefore necessary to manually open the coffin insertion door of the main combustion chamber and, on the one hand, to promote the combustion process with a poker and, on the other hand, to position bones so that they can fall through the grate. Above all, the lower and upper arm bones as well as the upper and lower leg bones are problematic in this respect.

Nachteilig bei dieser Vorgehensweise ist, daß während des "Schürvorgangs" die Mitarbeiter des Krematoriums einmal erhöhter Hitzestrahlung und Schadgasbelastung aus dem Hauptbrennraum ausgesetzt sind. Ferner wird durch den im Hauptbrennraum vorhandenen, vorgeschriebenen Unterdruck von 0,2 hPa und mehr Kaltluft über die geöffnete Sargeinfuhrtür in den Hauptbrennraum eingesogen, die für die laufenden Verbrennungsvorgänge ungünstig ist (Dioxinbildung) und zusätzlich bei dem weiteren Verbrennungsvorgang erwärmt werden muß. Dieses erhöht den Energiebedarf des Krematoriums.The disadvantage of this procedure is that during the "stoking process" the employees of the crematorium are exposed to increased heat radiation and harmful gas pollution from the main combustion chamber. Furthermore, the existing negative pressure of 0.2 hPa and more in the main combustion chamber draws cold air into the main combustion chamber via the open coffin introduction door, which is unfavorable for the ongoing combustion processes (formation of dioxins) and must also be heated during the further combustion process. This increases the energy requirements of the crematorium.

Hiervon ausgehend liegt der Erfindung das Problem zugrunde, eine Vorrichtung zum Tragen des Sarges innerhalb eines Hauptbrennraums eines Einäscherungsofens zu schaffen, durch die der Verbrennungsvorgang verbessert ist und insbesondere kein manueller Schür- und Rostreinigungseingriff von außen erforderlich ist.Proceeding from this, the invention is based on the problem of creating a device for carrying the coffin within a main combustion chamber of a cremation furnace, by means of which the combustion process is improved and in particular no manual stoking and grate cleaning intervention from the outside is required.

Dieses Problem wird erfindungsgemäß dadurch gelöst, daß der Rost beweglich ausgebildet ist.This problem is solved according to the invention in that the grate is designed to be movable.

Der Sarg kann während des Verbrennungsvorganges durch den beweglichen Rost in eine Rüttelbewegung versetzt werden, so daß verbrannte Schichten von unverbrannten Schichten abgelöst werden. Hierdurch wird das Verbrennungsgut geschürt. Ferner können sich durch die Bewegung des Rostes die zunächst in Längsrichtung des unverbrannten Sarges gesehen liegenden Knochen querstellen, so daß auch sie durch den Rost fallen. Ein manueller Eingriff von außen ist aufgrund der erfindungsgemäßen Vorrichtung somit nicht mehr erforderlich.The coffin can be set in a shaking motion by the movable grate during the combustion process, so that burnt layers are detached from unburned layers. As a result, the combustion material is stoked. Furthermore, the movement of the Rust, cross the bones that are initially seen in the longitudinal direction of the unburned coffin so that they also fall through the grate. A manual intervention from the outside is therefore no longer necessary due to the device according to the invention.

Vorzugsweise ist der Rost durch mehrere, in Längsrichtung des Sarges gesehen, hintereinanderliegende, um ihre Achse drehbare Rollen gebildet. Hierdurch ergibt sich ein besonders einfacher konstruktiver Aufbau des Rostes. Die Rollen sind vorteilhafterweise in drehendem Sinne antreibbar, wobei es zweckmäßig ist, wenn die Rollen individuell angetrieben sind. Die Rollen können hierdurch mal gleichsinnig, mal gegensinnig zueinander angetrieben werden, so daß eine besonders gute Schürwirkung erreicht wird. Die Rollen können aufgrund ihres Drehantriebes auch zum Einfahren des Sarges als Förderorgan genutzt werden. Dabei müssen allerdings die Füße des Sarges abgenommen oder Holzlatten untergelegt werden.The grate is preferably formed by a plurality of rollers, one behind the other, seen in the longitudinal direction of the coffin, rotatable about its axis. This results in a particularly simple structural design of the grate. The rollers can advantageously be driven in a rotating sense, it being expedient if the rollers are driven individually. As a result, the rollers can be driven in the same direction, sometimes in opposite directions, so that a particularly good stoking effect is achieved. Due to their rotary drive, the rollers can also be used as a conveyor to retract the coffin. However, the feet of the coffin must be removed or wooden slats placed under them.

Weitere Merkmale der Erfindung beziehen sich auf die Ausgestaltung der Rollen.Further features of the invention relate to the design of the roles.

Der Einäscherungsofen 10 ist in der üblichen Weise ausgebildet, nämlich mit einem Hauptbrennraum 11 und einer Ausglühzone 12. Ausglühzone 12 und Hauptbrennraum 11 sind durch eine Drehplatte 13, auf der auch die Nachverbrennung der herabfallenden Feststoffe durchgeführt wird (Nachbrennzone 43), voneinander abgeteilt. Während ein neuer Sarg 14 in dem Hauptbrennraum 11 verbrannt wird, kann die Asche des vorhergehenden Sarges in der Ausglühzone 12 ausglühen. Während des Ausglühens ruht die Asche innerhalb der Ausglühzone 12 auf einem Aschedrehrost 15.The cremation furnace 10 is designed in the usual way, namely with a main combustion chamber 11 and a glow zone 12. The glow zone 12 and the main combustion chamber 11 are separated from one another by a rotary plate 13, on which the post-combustion of the falling solids is also carried out (afterburning zone 43). While a new coffin 14 is being burned in the main combustion chamber 11, the ashes of the previous coffin can burn out in the annealing zone 12. During the annealing, the ash rests on a rotating ash grate 15 within the annealing zone 12.

Der Einäscherungsofen 10 weist die übliche Ausmauerung 16 auf, die durch einen außenliegenden Kühlmantel 17 umschlossen ist. Durch einen Eintritt 18 kann Kühlluft in den Kühlmantel 17 eingeleitet werden, die sodann die Ausmauerung umströmt und durch einen Austritt 19 abgefördert wird. Durch eine Sargeinfuhrtür 20 können die zu verbrennenden Särge 14 in den Hauptbrennraum eingefahren werden. Das bei der Einäscherung entstehende Abgas wird durch ein Abgasrohr 21 abgeleitet.The cremation furnace 10 has the usual lining 16, which is enclosed by an external cooling jacket 17. Cooling air can be introduced into the cooling jacket 17 through an inlet 18, which then flows around the brick lining and is discharged through an outlet 19. The coffins 14 to be burned can be moved into the main combustion chamber through a coffin insertion door 20. The exhaust gas generated during the cremation is discharged through an exhaust pipe 21.

Innerhalb des Hauptbrennraums 11 liegt der Sarg 14 mit seiner Wanne 22 auf einem Rost 23 auf. Der Rost 23 ist aus im vorliegenden Fall in Längsrichtung des Sarges 14 gesehen hintereinanderliegenden Rollen 24, 25, 26 und 27 gebildet. Die Rollen 24..27 erstrecken sich quer zur Längsrichtung des Sarges 14. Der lichte Abstand zwischen den Rollen 24..27 beträgt 300 mm. Die Rollen 24..27 sind derart im Hauptbrennraum 11 gelagert, daß sie bündig unterhalb einer Sargeinfuhrebene 42 angeordnet sind. Die Rollen 24..27 sind im wesentlichen aus einem Rohr 28, z. B. aus warmfestem (ca. 500°C) und oxidationsbeständigem Stahl hergestellt, welches mit einem wärmeisolierenden festen Mantel 29 ummantelt ist. Wie insbesondere in Fig. 2 erkennbar, ist der Mantel 29 bis in den Bereich von Bohrungen 30 in der Ausmauerung 16 des Einäscherungsofens 10 geführt. Das Rohr 28 einer jeden Rolle 24..27 ist bis in den Kühlmantel 17 geführt. Durch radial gerichtete Bohrungen 31 kann Kühlluft aus dem Kühlmantel 17 in das Rohr eingeleitet werden. Die Kühlluft durchströmt das Rohr und tritt durch Bohrungen 32 am anderen Ende aus dem Rohr 28 wieder aus.Within the main combustion chamber 11, the coffin 14 rests with its trough 22 on a grate 23. The grate 23 is formed from rollers 24, 25, 26 and 27 lying one behind the other in the present case, seen in the longitudinal direction of the coffin 14. The rollers 24..27 extend transversely to the longitudinal direction of the coffin 14. The clear distance between the rollers 24..27 is 300 mm. The rollers 24..27 are mounted in the main combustion chamber 11 in such a way that they are arranged flush below a coffin insertion level 42. The roles 24..27 are essentially from a tube 28, for. B. made of heat-resistant (approx. 500 ° C) and oxidation-resistant steel, which is coated with a heat-insulating solid jacket 29. As can be seen in particular in FIG. 2, the casing 29 is guided into the area of bores 30 in the lining 16 of the cremation furnace 10. The tube 28 of each roller 24.27 is guided into the cooling jacket 17. Cooling air can be introduced into the tube from the cooling jacket 17 through radially directed bores 31. The cooling air flows through the tube and exits the tube 28 through bores 32 at the other end.

Der Durchmesser des Rohres 28 beträgt günstigerweise 100 mm bei einer Wandstärke von mehr als 8 mm. Der Mantel 29 ist aus einer verschleißfesten Stampfmasse mit einer Wärmebeständigkeit von ca. 1.200 °C und einer Stärke von ca. 100 mm hergestellt. Es ergibt sich somit ein Gesamtdurchmesser der Rollen 24..27 von 300 mm.The diameter of the tube 28 is advantageously 100 mm with a wall thickness of more than 8 mm. The jacket 29 is made of a wear-resistant ramming compound with a heat resistance of approx. 1200 ° C. and a thickness of approx. 100 mm. This results in a total diameter of the rolls 24-27 of 300 mm.

An den Stirnseiten des Rohres 28 sind Wellen 33 und 34 fest angebracht. Durch Lager, insbesondere Kugellager 35, sind die Rohre 28 über die Wellen 33, 34 abgestützt. Hierzu sind an der Außenseite des Kühlmantels 17 Lagerflansche 36 angebracht.Shafts 33 and 34 are fixedly attached to the end faces of the tube 28. The tubes 28 are supported by the shafts 33, 34 by bearings, in particular ball bearings 35. For this purpose, 17 bearing flanges 36 are attached to the outside of the cooling jacket.

Jede der Rollen 24..27 ist über einen Motor antreibbar. Hierfür ist ein elektrischer Drehmotor 37 vorgesehen, der auf die Welle 34 aufgesteckt ist. Über eine Drehmomentstütze 38 ist der Drehmotor 37 am Lagerflansch 36 abgestützt. Jede der Rollen 24..27 verfügt dabei über einen eigenen Drehmotor 37. Jeder der Drehmotoren 37 ist für sich ansteuerbar. Jede der Rollen 24..27 ist somit individuell antreibbar. Die Drehmotoren 37 sind beispielsweise durch eine Isolierzwischenlage (nicht dargestellt) thermisch vom Einäscherungsofen 10 entkoppelt.Each of the rollers 24..27 can be driven by a motor. For this purpose, an electric rotary motor 37 is provided, which is attached to the shaft 34. The rotary motor 37 is supported on the bearing flange 36 via a torque arm 38. Each of the rollers 24..27 has its own rotary motor 37. Each of the rotary motors 37 can be controlled independently. Each of the rollers 24..27 can thus be driven individually. The rotary motors 37 are thermally decoupled from the cremation furnace 10, for example by an intermediate insulating layer (not shown).

Die einzelnen Phasen der Einäscherung sind ebenfalls in den Figuren näher dargestellt. Fig. 1 und 2 zeigen den frisch eingesetzten, noch vollständig intakten Sarg 14 mit seiner Wanne 22 und einem Deckel 39.The individual phases of cremation are also shown in more detail in the figures. 1 and 2 show the freshly inserted, still completely intact coffin 14 with its trough 22 and a lid 39.

Fig. 3 und 4 zeigen den Sarg bei schon vollständig verbranntem Deckel 39. Auch die Wanne 22 des Sarges 14 ist schon deutlich verbrannt. In dieser Phase kann es bereits zweckmäßig sein, das Einäscherungsgut zu bewegen und dadurch zu schüren. Hierzu werden die Rollen 24..27 im drehenden Sinne angetrieben. Dabei werden die Rollen 24..27 kurzzeitig (z. B. 1/5tel Umdrehung) linksdrehend und anschließend rechtsdrehend angetrieben. Die maximale Drehzahl der Rollen 24..27 liegt dabei bei etwa 0,5 min-1. Durch die Bewegung des Sarges 14 fallen bereits verbrannte Schichten ab. Der Sauerstoffzutritt zu unverbrannten Schichten wird erleichtert und das Feuer dadurch geschürt.3 and 4 show the coffin with the lid 39 already completely burned. The trough 22 of the coffin 14 is also clearly burned. In this phase it may already be useful to move the cremation material and thereby stir it up. For this purpose, the rollers 24-27 are driven in a rotating sense. The rollers 24..27 are briefly driven (e.g. 1/5 of a turn) counterclockwise and then clockwise. The maximum speed of the rollers 24..27 is about 0.5 min -1 . Already burned layers fall off due to the movement of the coffin 14. Oxygen access to unburned layers is facilitated and the fire is thereby fueled.

Fig. 5 und 6 zeigen den Sarg bereits nahezu vollständig verbrannt. Einzelne Knochen 40 liegen auf dem Rost auf. In diesem Stadium werden die äußeren Rollen 24 und 27 nach innen drehend angetrieben. Auf dem Rost 23 bzw. den Rollen 24..27 liegende Rückstände werden somit gut der sich verjüngenden Nachbrennzone 43 auf der Drehplatte 13 zugeführt. Die mittleren Rollen 25 und 26 werden mal links-, mal rechtsdrehend angetrieben. Der Verbrennungsvorgang wird hierdurch weiter geschürt. Gleichzeitig können auf den Rollen 24..27 in deren Querrichtung aufliegende Knochen 40, die infolge ihrer Länge nicht durch den Zwischenraum zwischen den Rollen hindurchfallen können, in Längsrichtung der Rollen 24..27 gedreht werden, so daß sie durch den Zwischenraum zwischen den Rollen 24..27 hindurchfallen können. Die Asche 41 des verbrannten Sarges und der Leiche sammeln sich auf der Drehplatte 13.5 and 6 show the coffin almost completely burned. Individual bones 40 lie on the grate. At this stage, the outer rollers 24 and 27 are driven to rotate inward. Residues lying on the grate 23 or the rollers 24..27 are thus well supplied to the tapered afterburning zone 43 on the rotary plate 13. The middle rollers 25 and 26 are sometimes driven to the left, sometimes to the right. This further fuels the combustion process. At the same time, bones 40 resting on the rollers 24..27 in their transverse direction, which due to their length cannot fall through the space between the rollers, can be rotated in the longitudinal direction of the rollers 24..27, so that they pass through the space between the rollers 24..27 can fall through. The ashes 41 of the burned coffin and the body collect on the rotating plate 13.

Die Rollen 24..27 müssen nicht, wie dargestellt, einen Runden Querschnitt aufweisen. Sie können vorteilhaft auch über einen drei-, vier- oder mehreckigen Querschnitt verfügen.The rolls 24..27 do not have to have a round cross-section as shown. You can also advantageously have a triangular, quadrangular or polygonal cross section.
