Description
Die Erfindung bezieht sich auf eine Einrichtung zur Überführung von in einem Ascheauffangraum einer Feuerstätte für Festbrennstoff anfallender Verbrennungsasche in eine von dem Festbrennstoffkessel entfernt angeordnete Entsorgungsvorrichtung.The invention relates to a device for transferring incurred in a ash catchment room of a solid fuel fireplace combustion ash in a remote from the solid fuel boiler disposal device.
Festbrennstoffkessel haben insbesondere in der Form von Pelletheizkesseln als Feuerstätten zur Wärmeversorgung von insbesondere privaten Wohnhäusern weite Verbreitung gefunden. Dabei sind für die Beschickung mit dem Brennstoff teilweise automatische Zuführvorrichtungen vorgesehen. Dagegen wird die in verhältnismäßig geringer Menge anfallende Verbrennungsasche in einer sog. Aschebox gesammelt. Wenn Letztere voll ist, muß sie von Hand entleert werden. Dieses Problem tritt gleichermaßen bei Zimmeröfen wie Kachelöfen, Kaminöfen oder dgl. auf.Solid fuel boilers, especially in the form of pellet boilers, have been widely used as fireplaces for supplying heat to, in particular, private homes. In this case, partial automatic feeders are provided for the feed with the fuel. By contrast, the combustion ash produced in a relatively small amount is collected in a so-called ash box. If the latter is full, it must be emptied by hand. This problem occurs equally in room ovens such as tiled stoves, stoves or the like.
Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Einrichtung der eingangs genannten Art zu schaffen, welche ohne manuellen Eingriff eine automatische Entsorgung der Verbrennungsasche ermöglicht.In contrast, the present invention seeks to provide a device of the type mentioned, which allows automatic disposal of the combustion ash without manual intervention.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine sich von dem Ascheauffangraum zu der Entsorgungsvorrichtung erstreckende Fördervorrichtung, durch die die Verbrennungsasche von dem Ascheauffangraum in die Entsorgungsvorrichtung förderbar ist.According to the invention, this object is achieved by a conveying device extending from the ash collecting space to the disposal device, by means of which the combustion ash can be conveyed from the ash collecting space into the disposal device.
Die von der Feuerstätte, beispielsweise dem Festbrennstoffkessel oder Zimmerofen, entfernt angeordnete Entsorgungsvorrichtung, bei der es sich beispielsweise um einen der Zwischenlagerung dienenden Lagerbehälter oder auch um einen geeignet ausgebildeten Anschluß zur Einspülung in den öffentlichen Abwasserkanal handelt, kann beispielsweise in der Garage, einem sonstigen Nebengebäude oder einem Mülltonnenunterstand bzw. im Bereich des Kanalanschlusses eines von der Feuerstätte mit Wärme versorgten Wohnhauses untergebracht sein. Durch die Fördervorrichtung gelangt die Verbrennungsasche von dem beispielsweise im Untergeschoß des Wohnhauses angeordneten Festbrennstoffkessel, der insbesondere ein Pelletheizkessel sein kann, in den verhältnismäßig großvolumigen Lagerbehälter. Letzterer kann insbesondere eine für ein öffentliches Entsorgungssystem vorgesehene Abfalltonne sein, die von dem Betreiber des Entsorgungssystems in regelmäßigen Zeitabständen entleert wird. Der üblicherweise vorhandene obere Deckel dieser Abfalltonne ist beim Betrieb der Überführungseinrichtung in seine Offenstellung geklappt und statt dessen die Deckelöffnung der Abfalltonne von dem austragsseitigen Endbereich der Fördervorrichtung abgedeckt. Dann kann die Abfalltonne für die Entleerung seitlich weggezogen, der Deckel zugeklappt und wie eine übliche Mülltonne in das Entsorgungsfahrzeug hinein entleert werden.The disposal of the fireplace, for example, the solid fuel boiler or room furnace, arranged disposal device, which is for example a storage storage serving storage container or a suitably trained connection for flushing in the public sewer, for example, in the garage, another outbuilding or a garbage can shelter or in the region of the sewer connection of a supplied by the fireplace with warm residential building. By the conveyor, the combustion ash passes from the example arranged in the basement of the house solid fuel boiler, which may be in particular a pellet boiler, in the relatively large-volume storage container. The latter may in particular be a waste bin intended for a public disposal system which is emptied by the operator of the disposal system at regular intervals. The usually present upper lid of this garbage bin is folded during operation of the transfer device in its open position and instead the lid opening of the garbage can covered by the discharge end of the conveyor. Then the bin can be pulled away laterally for emptying, the lid closed and emptied into the disposal vehicle like a common garbage can.
Der im Rahmen der Erfindung vorgesehene alternative Gedanke, die mit der Fördervorrichtung von der Feuerstätte abgeförderte Verbrennungsasche zu ihrer endgültigen Entsorgung in den öffentlichen Abwasserkanal hinein wegzuspülen, ist in einer zweckmäßigen Ausführungsform derart gestaltet, daß die Entsorgungsvorrichtung ein von der Fördervorrichtung mit der Verbrennungsasche beschickbarer Behälter ist, in dem die Verbrennungsasche mit Wasser zusammenführbar und in einen Abwasserentsorgungskanal ableitbar ist. Insbesondere kann es sich bei dem Behälter um einen Sammelschacht einer Abwasserhebeanlage handeln, in den die Verbrennungsasche von der Fördervorrichtung eingetragen wird. Von dort wird die Verbrennungsasche mittels der in dem Sammelschacht angeordneten Abwasserpumpe zusammen mit dem in dem Sammelschacht befindlichen Abwasser in den Abwasserentsorgungskanal gefördert. Sofern das Gebäude, in dem sich die Feuerstätte befindet, nicht ohnehin mit einer Hebeanlage ausgestattet ist, kann beispielsweise in einem Technikraum ein separater Behälter vorgesehen sein, in dem die von der Fördervorrichtung zugeführte Verbrennungsasche mit Wasser vermischt und über eine Pumpe in den öffentlichen Kanal entsorgt wird.The proposed in the context of the invention alternative idea, wegzubelülen with the conveyor from the hearth incinerated combustion ash for their final disposal in the public sewer into, is designed in an expedient embodiment such that the disposal device is a feedable from the conveyor to the combustion ash container in which the combustion ash can be combined with water and discharged into a sewage disposal channel. In particular, the container may be a collecting shaft of a sewage lifting plant into which the combustion ash is introduced by the conveying device. From there, the combustion ash by means of arranged in the collecting shaft sewage pump together with the wastewater located in the collecting shaft in promoted the sewage disposal channel. If the building in which the hearth is located, is not already equipped with a lifting system, for example, in a technical room, a separate container may be provided in which the supplied from the conveyor combustion ash mixed with water and disposed of via a pump in the public channel becomes.
Vorzugsweise ist die Fördervorrichtung eine pneumatische Fördervorrichtung mit einer sich zwischen dem Ascheauffangraum und der Entsorgungsvorrichtung erstreckenden Förderleitung und einem einen Förderluftstrom erzeugenden Fördergebläse. Insbesondere kann diese Förderleitung eine Rohrleitung aus nicht brennbarem Material sein, die beispielsweise aus starren Rohrabschnitten und Rohrbögen in Anpassung an die Gebäudeverhältnisse fest verlegt ist. Insbesondere besteht die Förderleitung zweckmäßig aus einem metallischen Werkstoff und ist zur Vermeidung statischer Aufladungen geerdet. Die Ausbildung in Form eines flexiblen Rohr- oder Schlauchgebildes ist jedoch nicht ausgeschlossen. Der Förderluftstrom und die Förderung der davon transportierten Verbrennungsascheteilchen können ohne Schwierigkeit dem durch die baulichen Gegebenheiten bedingten Verlauf des Förderweges folgen.Preferably, the conveying device is a pneumatic conveying device with a conveying line extending between the ash collecting space and the disposal device and a conveying blower producing a conveying air flow. In particular, this delivery line may be a pipeline made of non-combustible material, which is permanently laid, for example, from rigid pipe sections and pipe bends in adaptation to the building conditions. In particular, the conveying line expediently consists of a metallic material and is earthed to avoid static charges. The training in the form of a flexible pipe or hose structure is not excluded. The conveying air flow and the promotion of the combustion ash particles transported by it can follow the course of the conveying path caused by the structural conditions without difficulty.
Zweckmäßigerweise ist das Fördergebläse ein Sauggebläse. Insbesondere kann Letzteres im Bereich des entsorgungsvorrichtungsseitigen Endes der Förderleitung angeordnet sein. Bei der Ausbildung der Entsorgungsvorrichtung als Lagerbehälter ist es weiterhin zweckmäßig, daß sich dieses Ende und das Sauggebläse nach Art einer Abdeckhaube über der Deckelöffnung des Lagerbehälters erstrecken und eine leckfreie Verbindung zwischen Letzterem und dem Ascheauffangraum der Feuerstätte ermöglichen.Conveniently, the conveyor fan is a suction fan. In particular, the latter can be arranged in the region of the disposal device end of the delivery line. In the formation of the disposal device as a storage container, it is also appropriate that extend this end and the suction fan in the manner of a cover over the lid opening of the storage container and allow a leak-free connection between the latter and the ash collection space of the fireplace.
Im Rahmen der Erfindung ist insbesondere auch vorgesehen, daß die Förderleitung ein zwischen einer Freigabestellung, in der die Förderleitung offen ist, und einer Sperrstellung, in der die Förderleitung verschlossen ist, schaltbares Ventil aufweist. Diese Maßnahme trägt dem Umstand Rechnung, daß die Abförderung der Asche zweckmäßigerweise nur in deren abgekühltem Zustand stattfindet, der sich einstellt, wenn der Festbrennstoffkessel für eine gewisse Zeitdauer außer Betrieb ist, wie es beispielsweise während der Nachtabsenkung der Heizung der Fall ist. Nach der Abförderung der abgekühlten Asche bei geöffnetem Ventil wird Letzteres in seine Sperrstellung geschaltet. Auf diese Weise wird im Betrieb des Festbrennbrennkessels eine unkontrollierte Luftzufuhr durch die Förderleitung verhindert.In the context of the invention, it is also provided in particular that the delivery line has a switchable valve between a release position in which the delivery line is open and a blocking position in which the delivery line is closed. This measure takes into account the fact that the discharge of the ashes expediently takes place only in the cooled state, which occurs when the solid fuel boiler is out of operation for a certain period of time, as is the case for example during the night reduction of the heating. After the discharge of the cooled ash when the valve is open, the latter is switched to its blocking position. In this way, an uncontrolled air supply is prevented by the delivery line during operation of the solid fuel boiler.
Wenn mehr als eine Feuerstätte, beispielsweise ein Festbrennstoffkessel und ein Kachelofen, vorgesehen sind, kann eine gemeinsame Förderleitung vorgesehen sein, an die jeweils der Ascheauffangraum jeder Feuerstätte über eine Zweigleitung und ein ihr zugeordnetes Ventil an die gemeinsame Förderleitung angeschlossen ist. Wenn das Fördergebläse in der gemeinsamen Förderleitung einen Förderluftstrom erzeugt, kann durch selektives Öffnen der Ventile jeweils diejenige Feuerstätte ausgewählt werden, aus der die Verbrennungsasche abgefördert werden soll.If more than one fireplace, such as a solid fuel boiler and a tiled stove, are provided, a common delivery line may be provided, to each of the ash collection space each fireplace is connected via a branch line and a valve associated with it to the common delivery line. If the conveyor blower generates a conveying air flow in the common delivery line, the fireplace in each case can be selected by selectively opening the valves, from which the combustion ash is to be discharged.
Für einen vollständig automatischen Betrieb ist in einer vorteilhaften Ausführungsform eine elektronische Steuervorrichtung vorgesehen, durch die das Ventil und/oder das Fördergebläse in Abhängigkeit von einem Betriebszustand der Feuerstätte schaltbar sind. Im Fall eines Festbrennstoffkessels kann diese Steuervorrichtung beispielsweise in dessen Steuerung integriert sein. Diese Steuervorrichtung hält beispielsweise im Normalbetrieb das Ventil in seiner Sperrstellung und das Fördergebläse in seinem abgeschalteten Zustand. Dadurch wird insbesondere verhindert, daß durch die Förderleitung im Normalbetrieb des Festbrennstoffkessels ein unerwünschter Lufteintritt stattfindet. In dessen abgeschaltetem Zustand während der Nachtabsenkung und/oder bei hinreichend niedriger Temperatur im Ascheauffangraum steuert dagegen die Steuervorrichtung das Ventil in seine Freigabestellung und setzt das Fördergebläse in Betrieb. Dadurch wird die Verbrennungsasche aus dem Ascheauffangraum des Festbrennstoffkessels von der Fördervorrichtung in die Entsorgungsvorrichtung überführt.For a fully automatic operation, an electronic control device is provided in an advantageous embodiment, by means of which the valve and / or the delivery blower are switchable as a function of an operating state of the fireplace. In the case of a solid fuel boiler, this control device may be integrated, for example, in its control. For example, in normal operation, this control device holds the valve in its blocking position and the delivery fan in its switched-off state. This prevents in particular that takes place through the delivery line in normal operation of the solid fuel boiler, an undesirable air inlet. In its switched-off state during night reduction and / or at a sufficiently low temperature in the ash collecting space on the other hand, the control device controls the valve in its release position and sets the conveyor fan in operation. Thereby, the combustion ash is transferred from the ash collecting space of the solid fuel boiler from the conveying device to the disposal device.
In einer zweckmäßigen Ausgestaltung dieses Gedankens ist vorgesehen, daß die elektronische Steuervorrichtung einen ihr zugeführten Istwert einer im Bereich des Ascheauffangraums herrschenden Temperatur mit einem vorgegebenen Schwellwert vergleicht und ansprechend auf einen ihr zugeführten Startbefehl einen Befehl zum Umschalten des Ventils in seine Freigabestellung sowie einen Einschaltbefehl für das Fördergebläse erzeugt, wenn der Istwert den Schwellwert nicht überschreitet. Hierdurch wird sichergestellt, daß die Absaugung der Verbrennungsasche aus der Feuerstätte ansprechend auf den Startbefehl, der manuell oder von einer übergeordneten Steuerung eingegeben werden kann, unterbleibt, wenn an der Feuerstätte die Temperatur der abzusaugenden Verbrennungsasche über dem Schwellwert, der beispielsweise auf 20 °C eingestellt werden kann, liegt. Dadurch wird vermieden, daß die Verbrennungsasche in einem zu heißen Zustand abgefördert wird.In an expedient embodiment of this idea, it is provided that the electronic control device compares an actual value of a temperature prevailing in the area of the ash exhaust space with a predetermined threshold and in response to a start command supplied to it a command to switch the valve to its release position and a switch-on for Conveying blower generated when the actual value does not exceed the threshold value. This ensures that the exhaust of the combustion ash from the hearth in response to the start command, which can be input manually or by a higher-level control, is omitted when the temperature of the combustion ash to be sucked off the threshold, which is set to 20 ° C, for example, at the fireplace can be, lies. This avoids that the combustion ash is carried away in a too hot state.
Zweckmäßigerweise erfolgt die Erzeugung des Einschaltbefehls für das Fördergebläse gegenüber der Erzeugung des Befehls zum Umschalten des Ventils in seine Freigabestellung mit einer vorgegebenen zeitlichen Verzögerung. Dadurch kann sichergestellt werden, daß das Ventil volständig geöffnet ist, wenn das Fördergebläse zur Absaugung der Verbrennungsasche in Betrieb genommen wird.The generation of the switch-on command for the delivery blower expediently takes place with respect to the generation of the command for switching the valve into its release position with a given time delay. As a result, it can be ensured that the valve is fully opened when the conveyor fan for exhausting the combustion ash is put into operation.
Zweckmäßig ist ferner vorgesehen, daß die Steuervorrichtung nach Ablauf einer vorgegebenen Zeitspanne einen Abschaltbefehl für das Fördergebläse und einen Befehl zum Umschalten des Ventils in seine Sperrstellung erzeugt. Hierdurch wird der Absaugbetrieb auf die vorgegebene Zeitspanne begrenzt. Letztere kann beispielsweise auf 180 sec eingestellt werden, was normalerweise zur vollständigen Absaugung der angesammelten Verbrennungsasche genügt.Suitably, it is further provided that the control device generates a shutdown command for the delivery fan and a command to switch the valve in its blocking position after a predetermined period of time. As a result, the suction is limited to the predetermined period. The latter can for example be set to 180 seconds, which normally suffices for complete exhaustion of the accumulated combustion ash.

In dem dargestellten Ausführungsbeispiel steuert diese Steuervorrichtung das im normalen Heizbetrieb seine Sperrstellung einnehmende Ventil 14 in seine Freigabestellung und schaltet das Sauggebläse der Saugvorrichtung 12 ein, wenn beispielsweise während der Nachtabsenkung in dem Festbrennstoffkessel keine Verbrennung stattfindet und die Verbrennungsasche ausreichend abgekühlt ist. Dadurch wird die Verbrennungsasche aus dem Ascheauffangraum 8 in den Lagerbehälter 7 überführt.The
