Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Abdichten einer Planiertüröffnung einer Koksofenkammer gemäß dem Oberbegriff der Ansprüche 1 bzw 15.The invention relates to an apparatus and a method for sealing a leveling door opening of a coke oven chamber 15 according to the preamble of claims 1 and 15.

Bei der Verkokung von Steinkohle wird üblicherweise die Kokskohle durch in der Kammerdecke befindliche Füllöcher in die Koksofenkammer eingefüllt. Bei dieser sogenannten Beschickung im Schüttbetrieb bilden sich unter den Füllöchern Schüttkegel, die während des Füllvorgangs mit einer Planiervorrichtung eingeebnet werden müssen, um den Kammerraum vollständig auszunutzen und unterhalb der Kammerdecke freien Abzugsraum für die Füllgase zu belassen.When coking coal, it is usually used Coking coal through filling holes in the chamber ceiling filled the coke oven chamber. With this so-called loading in bulk operation, form under the filling holes Pouring cone during the filling process with a leveling device must be leveled to the chamber space fully exploit and free below the chamber ceiling Leave the discharge space for the filling gases.

Die zum Planieren erforderliche Vorrichtung mit einer von außen durch eine sogenannte Planiertüröffnung in die Ofenkammer einfahrbaren Planierstange ist üblicherweise auf der im Folgenden als Druckmaschine bezeichneten Koksausdrückmaschine montiert. Diese Druckmaschine ist längs der Koksofenbatterie von Koksofenkammer zu Koksofenkammer verfahrbar, um mit einer Druckstange den ausgegarten Kokskuchen aus der Ofenkammer zur gegenüberliegenden Koksofenseite hin hinauszudrücken und um danach beim erneuten Beschicken der Koksofenkammer die Kokskohle mittels der Planiervorrichtung einzuebnen. Ferner weist die Druckmaschine Betätigungsvorrichtungen zum Öffnen und Schließen bzw. Verriegeln der auf der Maschinenseite befindlichen Koksofenkammertüren und der die Planiertüröffnung verschließenden Planiertüren auf.The device required for leveling with one of outside through a so-called leveling door opening into the furnace chamber retractable bulldozer is usually on the hereinafter referred to as a coke press machine assembled. This press is along the coke oven battery movable from coke oven chamber to coke oven chamber in order to the cooked coke cake from the Push the oven chamber out to the opposite coke oven side and afterwards when re-loading the coke oven chamber the coking coal by means of the leveling device flatten. The printing press also has actuating devices to open and close or lock the the coke oven chamber doors on the machine side and the the leveling doors closing the leveling door.

Aus der DE 33 40 067 C2 ist eine Abdichteinrichtung für die Planiertüröffnung mit einem dichtend an die Planiertüröffnung anschließbaren Gehäuse bekannt, von dem ein Überleitrohr zu einer benachbarten Koksofenkammer abzweigt.DE 33 40 067 C2 is a sealing device for the Bulldozer door opening with a sealing to the bulldozer door opening connectable housing known from which a transfer tube to branches into an adjacent coke oven chamber.

Die DE-AS 11 27 868 offenbart eine Vorrichtung zur Vermeidung des Austretens der Füllgase durch die Planiertüröffnung mit einem die Planierstange umschließenden Rohr, dessen Länge etwa gleich dem Abstand zweier benachbarter Querstege der Planierstange ist.DE-AS 11 27 868 discloses a device for avoidance the escape of the filling gases through the leveling door opening a pipe surrounding the leveling rod, the length of which is approximately equal to the distance between two adjacent crossbars of the leveling bar is.

In der US 22 68 316 werden Dichtbleche beschrieben, die den Spalt zwischen der Planiertüröffnung und de Planierstange während des Planierens abdichten.In US 22 68 316 sealing plates are described, the Gap between the leveling door opening and the leveling bar seal during leveling.

Die US 4 264 263 offenbart ein Gehäuse zum Abdichten der Planiertüröffnung in dem die Lücken zwischen der Gehäusewand und der Planierstange mit beweglichen Walzen abgedichtet werden.US 4,264,263 discloses a housing for sealing the leveling door opening in which the gaps between the housing wall and the leveling rod can be sealed with movable rollers.

Es ist aus der DE 23 64 458 C3 bekannt, während des Planiervorganges ein Gehäuse, durch das die Planierstange geführt ist, an die Planiertüröffnuhg dichtend anzuschließen. Dieses Gehäuse ist sowohl mit einem Druckgebläse, als auch mit einem Sauggebläse verbunden. Mit dem Druckgebläse wird über Düsen Lüft in Richtung der Planiertüröffnung geblasen und dort mit dem Sauggebläse abgesaugt. Die Saugung ist mit einer Drossel derart einstellbar, dass außerhalb der Planiertüröffnung in dem Gehäuse ein Luftverschluss entstehen soll, der den Austritt von Gasen und Flammen aus der Planiertüröffnung verhindern soll. Auf diese Weise soll vor der Planiertüröffnung ein geschlossener Raum geschaffen werden, in dem sich ein Druck entsprechend dem Druck in der Koksofenkammer aufbaut, so dass entsprechend dem Druck in der Koksofenkammer aufbaut, so dass eine merkliche Druckdifferenz zwischen der Koksofenkammer und dem Raum vor der Planiertüröffnung nicht besteht. Durch diese Vorrichtung wird der Austritt von Füllgasen aus der Planiertüröffnung prinzipiell verhindert. Es ist jedoch ein großer apparativer Aufwand erforderlich. Die Einstellung der Saugung mit einer Drossel ist relativ ungenau, so daß unter Umständen Luft in die Koksofenkammer eingeblasen wird oder Füllgase aus der Koksofenkammer abgesaugt werden.It is known from DE 23 64 458 C3 during the leveling process a housing through which the bulldozer is guided is to seal the bulldozer opening. This Housing is both with a pressure blower, as well as with a Suction fan connected. With the pressure blower is over nozzles Blown in the direction of the leveling door opening and there with sucked off the suction fan. The suction is with a throttle adjustable so that outside the leveling door opening in the housing is to be provided with an air seal that prevents the outlet Prevent gases and flames from opening the leveling door should. In this way, one should open the leveling door closed space can be created in which there is a pressure builds up according to the pressure in the coke oven chamber, so that builds up according to the pressure in the coke oven chamber so that a noticeable pressure difference between the coke oven chamber and the room in front of the leveling door does not exist. Through this Device is the exit of filling gases from the leveling door opening in principle prevented. However, it is a large expenditure on equipment required. Setting the suction with a throttle is relatively imprecise, so that there may be air in the Coke oven chamber is blown in or fill gases from the coke oven chamber be sucked off.

Der Erfindung liegt die Aufgabe zugrunde, einfache Vorrichtungen und Verfahren zur Verfügung zu stellen, die einen geschlossenen Raum außerhalb der Planiertüröffnung gewährleisten und damit die Emissionen von Füllgasen durch die Planiertüröffnung verhindern.The invention has for its object simple devices and methods to provide one Ensure closed space outside the leveling door opening and thus the emissions of filling gases through the Prevent leveling door opening.

Diese Aufgabe wird hinsichtlich einer Vorrichtung durch die Merkmale der unabhängigen Vorrichtungsansprüche 1 und 9 sowie hinsichtlich eines Verfahrens durch den Patentanspruch 15 gelöst.This object is achieved with a device by Features of independent device claims 1 and 9 and with regard to a method by the claim 15 solved.

Weiterbildungen sind in den Unteransprüchen aufgeführt.Further training is listed in the subclaims.

Die Erfindung beruht auf den Grundgedanken, daß der in der Koksofenkammer während des Füllens mit Kokskohle vorhandene Unterdruck auch im Bereich der Planiertür aufrechterhalten wird.The invention is based on the basic idea that the in Coke oven chamber present during filling with coking coal Maintain negative pressure in the area of the leveling door becomes.

In einem Raumbereich vor der geöffneten oder vor und/oder in der Planiertüröffnung wird eine Abdichtung erzielt, die in ihrer Dichtfunktion einer geschlossenen Planiertür entspricht. Der Raumbereich vor und/oder in der Planiertüröffnung ist entweder durch strömungstechnische Maßnahmen, d. h. Herstellen von Druckgleichheit vor und hinter der Planiertüröffnung, wodurch eine Strömungstotzone erreicht wird, oder durch mechanische Abdichtungen der Planierstange möglich. In a room area in front of the open or in front of and / or in A seal is achieved in the leveling door opening their sealing function corresponds to a closed leveling door. The area in front of and / or in the leveling door opening is either by fluidic measures, d. H. Creating equal pressure in front of and behind the leveling door opening, whereby a current dead zone is reached, or possible by mechanical sealing of the leveling bar.

Das Sauggebläse nach Anspruch 1 wird - vorzugsweise - derart eingestellt, daß eine Strömung in dem Raum vor der Planiertüröffnung nicht mehr auftritt. Dadurch entsteht in dem Raum vor und/oder in der Planiertüröffnung eine strömungsmäßige Totzone. Die Strömung in diesem Raumbereich wird an einer Meßstelle gemessen und das Meßsignal wird zur Regelung oder Steuerung des Sauggebläses verwendet.The suction fan according to claim 1 is - preferably - such set a flow in the room in front of the bulldozer opening no longer occurs. This creates in the room a flow in front of and / or in the leveling door opening Dead zone. The flow in this area is at one Measuring point measured and the measuring signal is used for control or Control of the suction fan used.

Es ist auch möglich das Sauggebläse so einzustellen, daß eine geringe Einsaugung von Umgebungsluft in die Koksofenkammer, die die Füllgasabsaugung nur gering beeinträchtigt, stattfinden kann. Auf jeden Fall treten auch bei dieser Fahrweise keine Füllgasemissionen an der Planiertüröffnung auf.It is also possible to adjust the suction fan in such a way that a low intake of ambient air into the coke oven chamber, which only slightly affects the filling gas extraction can take place. In any case, this also occur Driving style no fill gas emissions at the leveling door opening on.

Es ist auch möglich den Ausgang des Sauggebläses mit einer benachbarten Koksofenkammer zu verbinden. Bei dieser Fahrweise wird der Unterdruck der benachbarten Koksofenkammer mitgenutzt. In diesem Fall wird die Saugung derart betrieben, daß Füllgase in den Nachbarofen gesaugt werden.It is also possible to use a suction fan outlet to connect neighboring coke oven chamber. With this driving style becomes the negative pressure of the neighboring coke oven chamber shared. In this case, the suction is operated in such a way that filling gases are sucked into the neighboring furnace.

Gemäß Anspruch 3 wird der Raum vor der Planiertüröffnung durch mechanische Abdichtung derart geschlossen, daß keine Füllgase austreten können. Durch die Dichtbleche wird die Planierstange oben und unten abgedichtet. Die seitliche Abdichtung der Planierstange erfolgt durch Dichtleisten. Durch diese Abdichtung der Planierstange von außen wird in Kombination mit den Querstegen ein geschlossener Hohlkasten gebildet, da die Dichtbleche mindestens den Bereich von zwei Querstegen abdichten.According to claim 3, the space in front of the bulldozer opening closed by mechanical sealing so that none Filling gases can escape. Through the sealing plates Leveling rod sealed at the top and bottom. The side seal the leveling rod is carried out by sealing strips. By this sealing of the leveling bar from the outside is combined with the cross bars a closed box girder formed since the sealing plates at least the range of two Seal cross bars.

Die Dichtbleche können derart gelagert sein, daß sie auf den Seitenstegen, auf den Querstegen oder auf Seiten- und Querstegen der Planierstange aufliegen. Sie können jedoch auch mit einem Anpreßmittel, z. B. Federn gegen die Seitenstege der Planierstange gedrückt werden. Die Verstärkung der Abdichtung durch die an den Seitenstegen der Planierstange anliegenden Dichtleisten, z. B. mittels Federn ist ebenfalls möglich.The sealing plates can be mounted such that they on the Side bars, on the cross bars or on side and cross bars of the leveling bar. However, you can too with a pressing means, e.g. B. springs against the side webs the leveling bar. The reinforcement of the waterproofing through the on the side bars of the bulldozer adjacent sealing strips, e.g. B. by means of springs is also possible.

Die Dichtbleche können auch derart in dem Gehäuse angeordnet sein, daß sie durch innerhalb der Planierstange anstehenden Unterdruck gegen die Planierstange gepreßt werden, wodurch ebenfalls die Abdichtwirkung erhöht wird.The sealing plates can also be arranged in the housing in this way be that they are coming from within the leveling bar Vacuum can be pressed against the leveling rod, whereby the sealing effect is also increased.

An ihren Kanten können die Dichtbleche mit Abrundungen und/oder Abschrägungen versehen sein. Dadurch wird verhindert, daß die Planierstange während des Planiervorganges gegen die Kanten der Dichtbleche stößt. Es ist auch möglich, das Dichtblech in mehrere Segmente zu unterteilen. Dadurch kann das Dichtblech eventuelle Unebenheiten der Planierstange und Querschnittsveränderungen besser abdichten.The sealing plates can be rounded and / or rounded at their edges Bevels. This prevents that the leveling rod during the leveling process against the Edges of the sealing plates bumps. It is also possible that Subdivide the sealing sheet into several segments. This can the sealing plate any unevenness of the leveling rod and Seal cross-sectional changes better.

Es ist auch möglich, mehrere Dichtbleche und Dichtleisten innerhalb des Gehäuses hintereinander anzuordnen. Dadurch wird die Abdichtwirkung ebenfalls erhöht.It is also possible to use several sealing plates and sealing strips to be arranged one behind the other within the housing. Thereby the sealing effect is also increased.

Zur besseren Haltbarkeit können die Dichtbleche mit Schleißmitteln ausgerüstet sein. Bei der Verwendung von Dichtblechen kann auf das Gehäuse verzichtet werden, da durch die Dichtbleche und die Seitenstege der Planierstange ein Gehäuse gebildet wird.For better durability, the sealing plates can be coated with abrasives be equipped. When using sealing sheets can be dispensed with, because of the Sealing plates and the side webs of the leveling bar form a housing is formed.

Der Planierkohlesammelbehälter kann beliebig außerhalb des Bereichs der Dichtbleche angeordnet sein.The leveling coal collecting container can be placed outside the Area of the sealing plates can be arranged.

Gemäß Anspruch 9 ist eine Abdichtung des inneren Querschnitts der Planierstange zwischen den Seitenstegen vorgesehen. Diese Abdichtelemente müssen derart beweglich ausgebildet sein, daß sie den Querstegen der Planierstange ausweichen können. Der Raum zwischen den Seitenstegen der Planierstange und dem Gehäuse wird durch ein oder mehrere hintereinander angeordnete Dichtleisten abgedichtet.According to claim 9 is a seal of the inner cross section the leveling bar between the side bars. These sealing elements must be designed to be movable be the crossbars of the leveling bar can dodge. The space between the side bridges of the Bulldozer and housing is made by one or more sealing strips arranged one behind the other sealed.

Die einfachste Möglichkeit ist die Anordnung von Pendelklappen in dem Gehäuse. Die Pendelklappen können hängend in z. B. einteiliger Klappenausführung in dem Gehäuse angeordnet sein. Sie dichten den Querschnitt zwischen den Seitenstegen der Planierstange ab. Bewegt sich die Planierstange, so drücken die Querstege der Planierstange bei Annäherung und Berührung gegen die Pendelklappe. Die Pendelklappe wird zur Seite geschoben und legt sich dichtend an die Oberkante des Quersteges der Planierstange an. Bewegt sich die Planierstange weiter so schwenkt die Pendelklappe wieder in den Raum zwischen den Seitenstegen und dichtet ihn ab, bis der nächste Quersteg erreicht ist.The simplest option is the arrangement of swing flaps in the housing. The pendulum flaps can be hanging in z. B. one-piece flap design arranged in the housing his. They seal the cross section between the side bars the leveling bar. If the leveling rod moves, so press the crossbars of the leveling bar when approaching and Touch against the pendulum flap. The pendulum flap becomes Pushed and lies sealingly on the upper edge of the Cross bar of the leveling bar. The bulldozer moves continue to swing the swing flap back into the Space between the side bars and seals it until the next crossbar is reached.

Eine weitere Möglichkeit wäre die Abdichtung des inneren Querschnitts der Planierstange durch Zellräder. Ober- und/oder unterhalb der Planierstange werden Zellräder in einem Zellradgehäuse derart angeordnet, daß die Zellradflügel in den Raum zwischen den Seitenstegen der Planierstange überlappend eingreifen. Bewegt sich die Planierstange, so wird durch die Querstege eine Drehung der Zellräder bewirkt.Another option would be to seal the inside Cross section of the bulldozer through cellular wheels. Upper and / or below the leveling rod are cellular wheels in one Cell wheel housing arranged such that the cell wheel blades in overlapping the space between the side bars of the leveling bar intervention. If the leveling rod moves, then caused by the crossbars a rotation of the cell wheels.

Das untere Zellradgehäuse kann mit einem Kohlenaustrag für die Planierkohle ausgerüstet sein.The lower cellular wheel housing can be used for a carbon discharge the leveling coal be equipped.

Das Zellrad kann auch so bemessen sein, daß die Zellradflügel, ähnlich wie die Pendelklappen den gesamten Querschnitt zwischen den Seitenstegen der Planierstange abdichten. In diesem Fall ist im unteren Teil des Gehäuses gegenüber dem Zellrad ein Dichtblech angeordnet, das mindestens den Bereich von zwei Querstegen der Planierstange abdichtet und auch aus dem Bodenblech eines die Planierstange umschließenden Gehäuses bestehen kann. The cellular wheel can also be dimensioned such that the cellular wheel wings, similar to the swing flaps the entire cross section seal between the side bars of the leveling bar. In this case is in the lower part of the case opposite Cell wheel arranged a sealing plate that at least the area sealed by two crossbars of the leveling bar and also from the bottom plate of a bulldozer enclosing Housing can exist.

Eine andere Möglichkeit der inneren Planierstangenabdichtung ist der Einbau von beweglichen Walzen in einem Walzengehäuse. Die Walzen sind derart bemessen, daß sie den gesamten Querschnitt zwischen den Seitenstegen der Planierstange einnehmen und abdichten. Die Walzen können sich innerhalb des Walzengehäuses auf- und abbewegen und so den Querstegen der Planierstange ausweichen.Another way of sealing the leveling rod inside is the installation of movable rollers in a roller housing. The rollers are sized so that they cover the entire Cross section between the side bars of the leveling bar ingest and seal. The rollers can get inside of the roller housing up and down and so the crossbars avoid the bulldozer.

Selbstverständlich können die Abdichtungen mehrfach in dem Gehäuse angeordnet sein. Es ist auch möglich, das Sauggebläse mit einer Abdichtung durch Dichtbleche und/oder beweglichen Abdichtelementen miteinander zu kombinieren.Of course, the seals can be multiple in the Housing be arranged.

In der Fig. 1 ist ein an beiden gegenüberliegenden Enden offenes Gehäuse 1 dargestellt, in das eine oben und unten offene Planierstange 2 mit Seitenstegen 3 und Querstegen 4 hinein- und herausfahren kann. Das Gehäuse 1 liegt dicht am Umfang einer Planiertüröffnung 5 einer Koksofenkammer 6 mit einem Steigrohr 7 an. Oberhalb des Gehäuses 1 ist ein Sauggebläse 8 mit einer an das Gehäuse 1 angeschlossenen Saugleitung 15 angeordnet. Mittels einer nicht dargestellten Regelung oder Steuerung wird das Sauggebläse so eingestellt, daß im wesentlichen keine Gasströmung in dem Gehäuse 1 nahe der Planiertüröffnung 5 der Koksofenkammer 6 stattfindet; vielmehr bildet sich eine Strömungstotzone 9 in einem zwischen dem Inneren der Koksofenkammer 6 und dem von der Planiertüröffnung 5 entfernten Ende des Gehäuses 1 bzw. der Saugleitung 15 gelegenen Bereich aus. Die Füllgase werden durch das Steigrohr 7 abgesaugt während Umgebungsluft durch das Sauggebläse 8 abgesaugt wird und nicht in die Koksofenkammer gelangt. Eine etwaige Strömung wird an einer Meßstelle 10 erfaßt.1 is one at both opposite ends open housing 1 shown, in one above and below open leveling bar 2 with side bars 3 and cross bars 4 can drive in and out. The housing 1 is close to Scope of a leveling door opening 5 with a coke oven chamber 6 a riser pipe 7. A suction fan is located above the housing 1 8 with a suction line connected to the housing 1 15 arranged. By means of a not shown Regulation or control, the suction fan is set so that substantially no gas flow in the housing 1 is close the leveling door opening 5 of the coke oven chamber 6 takes place; rather, a flow dead zone 9 forms in between the inside of the coke oven chamber 6 and that of the leveling door opening 5 distal end of the housing 1 and the Suction line 15 located area. The filling gases are aspirated through the riser pipe 7 while ambient air the suction fan 8 is sucked off and not into the coke oven chamber arrives. Any flow is at a measuring point 10 recorded.

Aus der Fig. 2 geht hervor, daß in dem Gehäuse 1 Dichtbleche 11 und 12 oberhalb und unterhalb der oben und unten offenen Planierstange 2 angeordnet sind.
