Description

Die Erfindung betrifft eine Vorrichtung zum Ausheben von Ofentüren eines Verkokungsofens mit
einem Türabhebekopf, der an vertikal sich erstreckende Ofentüren eines Horizontalkammerofens ankuppelbar ist,
einer Antriebseinrichtung für Stellbewegungen des Türabhebekopfes und
einer Absaughaube, die oberhalb der Ofentüren entlang des Horizontalkammerofens verfahrbar ist.The invention relates to a device for lifting oven doors of a coking oven with
a door lift head which can be coupled to vertically extending oven doors of a horizontal chamber oven,
a drive device for actuating movements of Türabhebekopfes and
a suction hood, which is movable above the furnace doors along the horizontal chamber furnace.

In einem modernen Kokereibetrieb werden beim Ausheben der Koksofentüren entstehende Emissionen durch eine Absaughaube, die mit der Bedienungsmaschine längs des Horizontalkammerofens verfahrbar ist und oberhalb der Türaushebeeinrichtung positioniert wird, aufgefangen und mittels Rohrleitungen entweder koksseitigen Entstaubungssystemen oder Filteranlagen, die auf der Bedienungsmaschine installiert sind, zugeführt. Die Länge der Absaughaube beträgt ein Mehrfaches der Kammerbreite einer Ofenkammer, um die beim Türausheben auftretenden Emissionen aufzufangen. Infolge der großen Kammerhöhe eines modernen Horizontalkammerofens, die oft mehr als 6 m beträgt, und infolge unvermeidbarer Luftbewegungen vor den Ofentüren werden noch erhebliche Mengen der beim Türöffnen freigesetzten Emissionen, insbesondere aus den unteren Ofentürbereichen, nicht von der Absaughaube erfasst und gelangen in die Umgebung. Nachteilig ist ferner, dass die Absaugleitungen, das Absauggebläse und vor allem Filteranlagen für große Luftmengen ausgelegt werden müssen.In a modern coking plant, emissions resulting from excavating the coke oven doors are captured by a suction hood, which is movable with the operating machine along the horizontal chamber oven and positioned above the door lift, and either piping coke-side dust removal systems or filtering equipment installed on the control machine. The length of the extraction hood is a multiple of the chamber width of a furnace chamber to absorb the emissions occurring at the door lift. Due to the large chamber height of a modern horizontal chamber furnace, which is often more than 6 m, and due to unavoidable air movements in front of the oven doors are still significant amounts of released during door opening emissions, especially from the lower oven door areas, not covered by the exhaust hood and get into the environment. A further disadvantage is that the suction lines, the exhaust fan and above all filter systems must be designed for large amounts of air.

Aus der JP 11-236571 A ist eine Voksofenbendienungsmachine bekannt, die eine nahezu vollständige Erfassung der Emissionen, die beim Öffnen der Ofentür oder beim koksdrücken auftreten, ermöglicht.From JP 11-236571 A a Voksofenbendienungsmachine is known, which allows almost complete detection of the emissions that occur when opening the oven door or Koksdrücken.

Der Erfindung liegt die Aufgabe zugrunde, die Absaugung der beim Öffnen der Ofentür auftretenden Emissionen zu verbessern.The invention has for its object to improve the suction of the emissions occurring when opening the oven door.

Ausgehend von einer Vorrichtung mit den eingangs beschriebenen Merkmalen wird die Aufgabe erfindungsgemäß dadurch gelöst, dass an dem Türabhebekopf Dichtungselemente angeschlossen sind, die beidseits einer zu öffnenden Ofentür gegen frontseitige Kontaktflächen des Horizontalkammerofens bewegbar sind, sich im Wesentlichen über die gesamte Höhe der Ofentür bis in den Absaugbereich der Absaughaube erstrecken und beim Öffnen der Ofentür einen Absaugraum für Türemissionen bilden. Die beim Öffnen der Ofentür an der Frontseite des Horizontalkammerofens anliegenden Dichtungselemente begrenzen einen nach oben offenen Absaugraum, der in den Absaugbereich der Absaughaube einmündet. Dadurch werden die beim Öffnen der Ofentür auftretenden Emissionen kanalisiert und können mit verhältnismäßig kleinen Luftmengen der Absaughaube gezielt zugeführt werden. Die erfindungsgemäße Anordnung ermöglicht eine nahezu vollständige Erfassung aller Emissionen, die beim Öffnen der Ofentür auftreten, insbesondere auch aus den unteren Türbereichen.Starting from a device having the features described above, the object is achieved in that are connected to the door lift sealing elements that are movable on both sides of an open oven door against front side contact surfaces of the horizontal chamber furnace, substantially over the entire height of the oven door into the Extracting the extraction hood extend and form a suction chamber for door emissions when opening the oven door. The applied when opening the oven door on the front side of the horizontal chamber oven sealing elements define an upwardly open suction, which opens into the suction of the suction hood. As a result, the emissions occurring when opening the oven door are channeled and can be selectively supplied with relatively small amounts of air to the extractor hood. The arrangement according to the invention enables almost complete detection of all emissions that occur when the oven door is opened, in particular also from the lower door areas.

Der Türabhebekopf weist zweckmäßig mechanische, elektromechanische, pneumatische oder hydraulische Stelleinrichtungen auf, welche die Stellbewegungen der Dichtungselemente so steuern, dass die Dichtungselemente während einer Aushubbewegung der an den Türabhebekopf angekuppelten Ofentür aus der Türöffnung an den frontseitigen Kontaktflächen des Horizontalkammerofens anliegen. Vorzugsweise sind die Dichtungselemente als schwenkbeweglich gelagerte Flügel ausgebildet. Sie können ferner als Schiebewände ausgebildet sein, die aus einer zurückliegenden Ruheposition in einer geradlinigen Stellbewegung gegen die frontseitigen Kontaktflächen des Horizontalkammerofens bewegbar sind. Ferner besteht die Möglichkeit, die Dichtungselemente ein oder mehrteilig auszubilden.The door lift head expediently has mechanical, electromechanical, pneumatic or hydraulic actuating devices which control the positioning movements of the sealing elements to control so that the sealing elements abut during a lifting movement of the coupled to the door lifting head furnace door from the door opening at the front contact surfaces of the horizontal chamber furnace. Preferably, the sealing elements are designed as pivotally mounted wings. They can also be designed as sliding walls, which are movable from a previous rest position in a rectilinear adjusting movement against the front contact surfaces of the horizontal chamber furnace. It is also possible to form the sealing elements in one or more parts.

Der Ankuppelvorgang der Türabhebeeinrichtung an eine zu öffnende Ofentür wird durch die erfindungsgemäß vorgesehenen Dichtungselemente nicht beeinträchtigt. Die Dichtungselemente sind zweckmäßig zwischen einer Ruheposition und einer Arbeitsposition bewegbar, wobei sie in der Ruhrposition so weit zurückgeschoben oder zurückgeschwenkt werden, dass der Ankuppelvorgang zwischen dem Türabhebekopf und der geschlossenen Ofentür beobachtet werden kann.The coupling process of the door lifting device to an oven door to be opened is not impaired by the sealing elements provided according to the invention. The sealing elements are expediently movable between a rest position and a working position, wherein they are so far pushed back or pivoted in the Ruhr position that the Ankuppelvorgang between the door lift head and the closed oven door can be observed.

Die erfindungsgemäße Anordnung ermöglicht die Verwendung kompakter und kleiner Absaughauben. Vorzugsweise weist die entlang des Horizontalkammerofens verfahrbare Absaughaube eine Länge auf, welche die Kammerbreite einer Ofenkammer des Horizontalkammerofens nicht wesentlich überschreitet. An die Absaughaube anschließende Absaugleitungen, das Absauggebläse und eine nachfolgende Filteranlage können für verhältnismäßig kleine Mengenströme ausgelegt werden.The arrangement according to the invention enables the use of compact and small suction hoods. Preferably, the suction hood movable along the horizontal chamber furnace has a length which does not substantially exceed the chamber width of a furnace chamber of the horizontal chamber furnace. Suction lines connecting to the suction hood, the exhaust fan and a subsequent filter system can be designed for relatively small flow rates.

Ferner ist eine Absaughaube vorgesehen, die oberhalb der Ofentüren entlang des Horizontalkammerofens verfahrbar ist und deren Absaugbereich 4 in den Figuren gestrichelt dargestellt ist. Sie ist oberhalb der Türabhebevorrichtung vor der zu öffnenden Ofenkammer des Horizontalkammerofens positioniert und weist im Ausführungsbeispiel sowie nach bevorzugter Ausführung der Erfindung eine Länge auf, welche die Kammerbreite der Ofenkammer nicht wesentlich überschreitet.In the figures, a door lift device is shown on a Koksausdrück- or Koksüberleitmaschine. It comprises a door lift head 1, which can be coupled to vertically extending furnace doors 2 of a horizontal chamber furnace, and comprises a drive means 3 only schematically indicated for actuating movements of Türabhebekopfes 1. Furthermore, a suction hood is provided, which is movable above the furnace doors along the horizontal chamber furnace and their Extraction area 4 is shown in dashed lines in the figures. It is positioned above the door lift device in front of the open oven chamber of the horizontal chamber furnace and has in the embodiment and according to a preferred embodiment of the invention has a length which does not substantially exceed the chamber width of the furnace chamber.

An den Türabhebekopf 1 sind Dichtungselemente 5 angeschlossen, die aus einer in Fig. 1 gestrichelt dargestellten Grundstellung I in eine in Fig. 1 mit durchgezogener Linie dargestellte Stellung II bewegbar sind. Zur Steuerung der Stellbewegungen sind mechanische, elektromechanische oder hydraulische Stelleinrichtungen vorgesehen. Vorzugsweise werden Stelleinrichtungen mit einem oder mehren Hydraulikzylindern eingesetzt.To the door lift head 1 sealing elements 5 are connected, which are movable from a dashed line in Fig. 1 illustrated basic position I in a position II shown in Fig. 1 by a solid line. To control the positioning movements mechanical, electro-mechanical or hydraulic actuators are provided. Preferably, adjusting devices are used with one or more hydraulic cylinders.

Der Türabhebekopf 1 wird aus der in Fig. 1 dargestellten Position in die in Fig. 2 dargestellte Position vorgefahren und an die zu öffnende Ofentür 2 angekuppelt. Bei der Vorwärtsbewegung sind die als schwenkbeweglich gelagerte Flügel ausgebildete Dichtungselemente aufgespreizt und nehmen die in Fig. 1 dargestellte Stellung II ein. Die Kupplung des Türabhebekopfes 1 an der Ofentür 2 erfolgt in an sich bekannter Weise, indem Abhebebalken des Abhebekopfes 1 in Klauen der Ofentür 2 eingehakt werden. In der Stellung II sind die Dichtungselemente soweit zurückgeschwenkt, dass der Ankuppelvorgang zwischen dem Türabhebekopf 1 und der geschlossenen Ofentür 2 beobachtet werden kann. Nach dem Ankuppeln werden die flügelartigen Dichtungselemente 5 gegen frontseitige Kontaktflächen 6 des Horizontalkammerofens bewegt und nehmen eine Arbeitsposition III ein. Im Ausführungsbeispiel sind die Kontaktflächen 6 an Ankerständern 7 ausgebildet. Die Dichtungselemente 5 erstrecken sich im Wesentlichen über die gesamte Höhe der Ofentür 2 bis in den Absaugbereich 4 der Absaughaube und bilden beim Öffnen der Ofentür 2 einen kanalförmigen Absaugraum 8 für Türemissionen.The door lift head 1 is moved from the position shown in FIG. 1 into the position shown in FIG. 2 and coupled to the oven door 2 to be opened. During the forward movement, the sealing elements mounted as pivotably mounted wings are spread open and assume the position II shown in FIG. The coupling of Türabhebekopfes 1 to the oven door 2 takes place in a conventional manner by lifting bars of the lift-off head 1 are hooked into claws of the oven door 2. In the position II, the sealing elements are pivoted back so far that the Ankuppelvorgang between the door lift head 1 and the closed oven door 2 can be observed. After coupling, the wing-like sealing elements 5 are moved against front-side contact surfaces 6 of the horizontal chamber furnace and take a working position III. In the exemplary embodiment, the contact surfaces 6 are formed on anchor stands 7. The sealing elements 5 extend substantially over the entire height of the oven door 2 into the suction area 4 of the suction hood and form a channel-shaped suction chamber 8 for door emissions when the oven door 2 is opened.

Das Ausheben der Ofentür aus der Türöffnung ist in Fig. 3 dargestellt. Die Stellbewegungen der Dichtungselemente 5 werden von den zugeordneten Stelleinrichtungen so gesteuert, dass die Dichtungselemente 5 während der Aushubbewegung der an den Türabhebekopf 1 angekuppelten Ofentür 2 aus der Türöffnung an den frontseitigen Kontaktflächen 6 des Horizontalkammerofens anliegen. Der Darstellung entnimmt man, dass die flügelartig ausgebildeten Dichtungselemente 5 sich auf den Flanschen der Ankerständer 7 in Richtung Ofentür 2 bewegen. Die auf der gesamten Höhe der Ofentür 2 austretenden Emissionen gelangen in den Absaugraum 8 und werden kanalisiert nach oben in Richtung der Absaughaube geleitet. Sie gelangen nicht in die Umgebung. Bevor die schwenkbeweglich gelagerten flügelartigen Dichtungselemente 5 die in Fig. 3 dargestellte Position IV erreichen, die der Grundstellung entspricht, kann die Fahrbewegung der Türabhebevorrichtung kurzzeitig gestoppt werden, um einen längeren Absaugzeitraum zu erhalten.The lifting of the oven door from the door opening is shown in Fig. 3. The adjusting movements of the sealing elements 5 are controlled by the associated adjusting devices so that the sealing elements 5 abut during the excavation movement of the door door 2 coupled to the door lifting head 1 from the door opening on the front contact surfaces 6 of the horizontal chamber furnace. The illustration shows that the wing-like sealing elements 5 move on the flanges of the anchor stand 7 in the direction of the oven door 2. The emissions exiting the entire height of the oven door 2 enter the suction chamber 8 and are channeled upwards in the direction of the suction hood. They do not get into the environment. Before the pivotally mounted wing-like sealing elements 5 reach the position IV shown in FIG. 3, which corresponds to the basic position, the driving movement of the door lift device can be stopped for a short time in order to obtain a longer suction period.
