Description
Die Erfindung betrifft ein Teleskoprohr für eine Austragseinrichtung an einem Beschickungswagen für Koksöfen mit einem Füllrohr, mit einem das Füllrohr umschließenden, vertikal verstellbaren Außenrohr, mit einer Dichtungsanordnung zur Abdichtung des Ringspaltes zwischen Füllrohr und dem Außenrohr, die eine das Füllrohr umschließende elastisch verformbare Dichtung aufweist, und mit einer auf die Dichtung wirkenden Spannvorrichtung, die einen Antrieb zum betriebsmäßigen Spannen und Lösen aufweist, wobei die Dichtung durch Spannen der Spannvorrichtung gegen das Füllrohr sowie gegen eine mit dem Außenrohr verbundene Flanschfläche pressbar ist und wobei die Dichtung durch Lösen der Spannvorrichtung von der Füllrohrwand wieder freikommt, so dass das Außenrohr ohne Verschleiß der Dichtung vertikal verstellbar ist.The invention relates to a telescopic tube for a discharge device on a loading cart for coke ovens with a filling pipe, with a filling pipe surrounding the filling pipe, vertically adjustable outer tube, with a sealing arrangement for sealing the annular gap between the filling pipe and the outer tube, which encloses the filling tube has elastically deformable seal, and with a the seal acting tensioner which is a drive for operational tensioning and loosening, the Seal by tensioning the tensioning device against the filling pipe as well as against a flange surface connected to the outer tube is compressible and the seal by loosening the Clamping device is released from the filling pipe wall, see above that the outer tube is vertical without wearing the seal is adjustable.
Beschickungswagen für einen modernen Koksofenbetrieb sind mit einem Teleskoprohr ausgestattet, welches die Einsatzkohle aus einer unterhalb eines Fülltrichters befindlichen Austragseinrichtung in die Koksofenkammer überleitet. Das Teleskoprohr ist mehrteilig ausgebildet und weist zumindest ein an die Austragseinrichtung angeschlossenes Füllrohr sowie ein heb- und senkbares Außenrohr auf. Besonderer Wert wird bei der Ausführung des Teleskoprohres auf eine dichte Ausführung gelegt, so dass während des Kohleeinfüllens in die Koksofenkammer keine Füllemissionen durch das Teleskoprohr in die Umwelt gelangen. Bei einem aus DE-C 29 22 571 bekannten Teleskoprohr weist das fest an die Austragseinrichtung angeschlossene Füllrohr an seinem unteren Ende einen ringförmigen, mit Sand gefüllten Kragen auf. Das vertikal verstellbare Außenrohr besitzt an seinem oberen Ende eine Dichtleiste, die beim Absenken des Außenrohres in das Sandbett eintaucht. Die bekannte Ausführung erlaubt es nicht, Höhendifferenzen zwischen der Unterkante des abgesenkten Außenrohres und dem Fülllochrahmen auszugleichen.Feed trolleys for a modern coke oven operation equipped with a telescopic tube, which the coal from one located below a hopper Discharge device transferred to the coke oven chamber. The Telescopic tube is formed in several parts and at least has a filling pipe connected to the discharge device and a lifting and lowering outer tube. Special value is in the execution of the telescopic tube on a tight Execution placed so that during the coal filling in the coke oven chamber no fill emissions through the telescopic tube get into the environment. In one from DE-C 29 22 571 Known telescopic tube has the discharge device connected filling pipe at its lower end a ring-shaped collar filled with sand. The has vertically adjustable outer tube on its upper End of a sealing strip, which when lowering the outer tube in submerges the sand bed. The known version allows it not, height differences between the lower edge of the lowered Compensate outer tube and the filling hole frame.
Durch örtliche Veränderungen des Mauerwerks der Ofendecke können beachtliche Höhenunterschiede entlang der Ofendecke auftreten, die bei der Befüllung der einzelnen Koksofenkammern von dem Teleskoprohr ausgeglichen werden müssen. Zu diesem Zweck werden in die Teleskoprohre Kompensatoren eingebaut, welche einerseits den Austritt von Füllemissionen verhindern und andererseits in einem gewissen Umfang aufgrund ihrer Dehnfähigkeit Höhendifferenzen von Fülllochrahmen zu Fülllochrahmen ausgleichen. Bei einer aus EP-B 0 632 117 bekannten Ausführung sind das fest mit der Austragseinrichtung verbundene Füllrohr und das heb- und senkbare Außenrohr von einer als Wellrohr ausgebildeten Manschette umgeben, die sich beim Absenken des Außenrohrs ausdehnt. Die Manschette, zumeist aus Stahl oder einem Spezialgewebe gefertigt, besitzt nur eine begrenzte Dehnfähigkeit, die in direktem Zusammenhang mit ihrer Baulänge steht und weder durch die konstruktive Ausführung noch durch die Materialwahl wesentlich beeinflussbar ist. In der Praxis, insbesondere bei älteren Koksofenanlagen, ist der Abstand zwischen der Unterkante des Teleskoprohres in angehobenem Zustand und der Oberkante der Fülllochrahmen oft größer als die zulässige Dehnung des Kompensators, so dass ganze Ofendeckenbereiche mit den Fülllochrahmen in aufwendigen und mit erheblichen Kosten verbundenen Aktionen angehoben und in den Bereich der zulässigen Kompensatordehnungen gebracht werden müssen.Due to local changes in the masonry of the furnace ceiling there can be considerable differences in height along the furnace ceiling occur when filling the individual coke oven chambers must be compensated by the telescopic tube. To for this purpose, compensators are installed in the telescopic tubes, which on the one hand the leakage of fill emissions prevent and on the other hand due to some extent their elasticity, height differences of filling hole frames equalize to fill hole frame. In one from EP-B 0 632 117 known version are fixed with the Discharge device connected filling tube and the lifting and lowerable outer tube from a corrugated tube Cuff surround that when lowering the outer tube expands. The cuff, usually made of steel or one Special fabric made, has only a limited stretch, which are directly related to their overall length stands and neither by the constructive execution nor can be significantly influenced by the choice of material. In the Practice, especially in older coke oven plants, is the Distance between the lower edge of the telescopic tube when raised Condition and the top edge of the fill hole frame often greater than the allowable expansion of the compensator, so that Entire furnace ceiling areas with the filling hole frames in complex and raised actions associated with significant costs and in the range of the allowable expansion joints have to be brought.
Ein Teleskoprohr mit den eingangs beschriebenen Merkmalen ist aus EP-A 0 396 877 bekannt. Bei der bekannten Ausführung ist eine das Füllrohr umschließende elastisch verformbare Dichtung vorgesehen, die in einem von zwei Flanschringen begrenzten und mit dem Außenrohr verbundenen ringförmigen Gehäuse angeordnet sowie radial von einem in das Gehäuse eingelegten Spannband beaufschlagt ist. Der Antrieb der Spannvorrichtung weist eine die Enden des Spannbandes zusammenziehende Zugeinrichtung auf.A telescopic tube with the features described above is known from EP-A 0 396 877. In the known version is an elastically deformable that surrounds the filling pipe Seal provided in one of two Flange rings limited and connected to the outer tube annular housing arranged radially from one in the tensioned strap is inserted into the housing. The Drive of the clamping device has one of the ends of the Tensioning band pulling drawbar on.
