Vorrichtung zum Ausheben von Ofentüren eines Verkokungsofens Device for lifting furnace doors of a coking furnace
Beschreibung:Description:
Die Erfindung betrifft eine Vorrichtung zum Ausheben von Ofentüren eines Verkokungsofens mitThe invention relates to a device for lifting furnace doors of a coking furnace

einer Antriebseinrichtung für Stellbewegungen des Türabhebekopfes unda drive device for adjusting the door lifting head and
einer Absaughaube, die oberhalb der Ofentüren entlang des Horizontalkammerofens verfahrbar ist .a suction hood that can be moved along the horizontal chamber furnace above the furnace doors.
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 Tür- aushebeeinrichtung positioniert wird, aufgefangen und mittels Rohrleitungen entweder koksseitigen Entstaubungs- systemen 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 freige- setzten Emissionen, insbesondere aus den unterenIn a modern coking plant, emissions arising when the coke oven doors are lifted are collected by a suction hood that can be moved along the horizontal chamber furnace with the operating machine and positioned above the door lifting device, and either piping-side dust extraction systems or filter systems installed on the operating machine by means of pipes are fed. The length of the suction hood is a multiple of the chamber width of a furnace chamber in order to absorb the emissions that occur when the door is lifted. 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 furnace doors, considerable amounts of the emissions released when the door is opened, especially from the lower ones
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.Oven door areas, not covered by the exhaust hood and get into the environment. Another disadvantage is that the suction lines, the suction fan and above all filter systems have to be designed for large amounts of air.
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 extraction of the emissions occurring when opening the furnace door.
Ausgehend von einer Vorrichtung mit den eingangs beschrie- benen Merkmalen wird die Aufgabe erfindungsgemäß dadurch gelöst, dass an dem Turabhebekopf 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 voll- ständige Erfassung aller Emissionen, die beim Öffnen der Ofentür auftreten, insbesondere auch aus den unteren Türbereichen.Starting from a device with the features described at the outset, the object is achieved according to the invention in that sealing elements are connected to the door lifting head which can be moved on both sides of an oven door to be opened against front-side contact surfaces of the horizontal chamber oven, essentially over the entire height of the oven door extend into the extraction area of the extraction hood and form a suction chamber for door emissions when the furnace door is opened. The sealing elements in contact with the front of the horizontal chamber furnace when the furnace door is opened limit a suction space that is open at the top and that opens into the suction area of the suction hood. As a result, the emissions that occur when the furnace door is opened are channeled and can be supplied to the exhaust hood with relatively small amounts of air. The arrangement according to the invention enables an almost complete recording of all emissions that occur when the furnace door is opened, in particular also from the lower door areas.
Der Turabhebekopf weist zweckmäßig mechanische, elektro- mechanische, pneumatische oder hydraulische Stelleinrichtungen auf, welche die Stellbewegungen der Dichtungsele- mente so steuern, dass die Dichtungselemente während einer Aushubbewegung der an den Turabhebekopf 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 lifting head expediently has mechanical, electromechanical, pneumatic or hydraulic actuating devices which control the actuating movements of the sealing elements. Control elements in such a way that the sealing elements lie against the front-side contact surfaces of the horizontal chamber furnace during a lifting movement of the furnace door coupled to the door lifting head from the door opening. The sealing elements are preferably designed as pivotably mounted wings. They can also be designed as sliding walls, which can be moved from a previous rest position in a rectilinear actuating movement against the front contact surfaces of the horizontal chamber furnace. There is also the possibility of forming the sealing elements in one or more parts.
Der Ankuppelvorgang der Türabhebeeinrichtung an eine zu öffnende Ofentür wird durch die erfindungsgemäß vorge- sehenen 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 Turabhebekopf 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 pushed back or pivoted back so far in the Ruhr position that the coupling process between the door lifting head and the closed furnace door can be observed.
Die erfindungsgemäße Anordnung ermöglicht die Verwendung kompakter und kleiner Absaughaube . 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. Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung erläutert. Es zeigen schematischThe arrangement according to the invention enables the use of compact and small suction hoods. The suction hood which can be moved along the horizontal chamber furnace preferably has a length which does not substantially exceed the chamber width of a furnace chamber of the horizontal chamber furnace. Suction lines connected to the suction hood, the suction fan and a subsequent filter system can be designed for relatively small flow rates.

In den Figuren ist eine Türabhebevorrichtung auf einer Koksausdrück- oder Koksüberleitmaschine dargestellt. Sie weist einen Turabhebekopf 1 auf, der an vertikal sich erstreckende Ofentüren 2 eines Horizontalkammerofens ankuppelbar ist, und umfasst eine nur schematisch angedeutete Antriebseinrichtung 3 für Stellbewegungen des Türabhebekopfes 1. 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 Ausführungs- beispiel sowie nach bevorzugter Ausführung der Erfindung eine Länge auf, welche die Kammerbreite der Ofenkammer nicht wesentlich überschreitet. An den Turabhebekopf 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, elektro- mechanische oder hydraulische Stelleinrichtungen vorgesehen. Vorzugsweise werden Stelleinrichtungen mit einem oder mehren Hydraulikzylindern eingesetzt.In the figures, a door lifting device on a coke pushing or coke transfer machine is shown. It has a door lifting head 1, which can be coupled to vertically extending furnace doors 2 of a horizontal chamber furnace, and comprises a drive device 3, indicated only schematically, for actuating movements of the door lifting head 1. Furthermore, a suction hood is provided which can be moved along the horizontal chamber furnace above the furnace doors and the like Suction area 4 is shown in dashed lines in the figures. It is positioned above the door lifting device in front of the furnace chamber of the horizontal chamber furnace to be opened and, in the exemplary embodiment and in accordance with the preferred embodiment of the invention, has a length which does not substantially exceed the chamber width of the furnace chamber. Sealing elements 5 are connected to the door lifting head 1 and can be moved from a basic position I shown in dashed lines in FIG. 1 to a position II shown in solid lines in FIG. 1. Mechanical, electromechanical or hydraulic actuating devices are provided to control the actuating movements. Actuators with one or more hydraulic cylinders are preferably used.
Der Turabhebekopf 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 Turabhebekopf 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 Arbeits- position 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. Das Ausheben der Ofentür aus der Türöffnung ist in Fig. 3 dargestellt. Die Stellbewegungen der Dichtungselemente 5 werden von den zugeordneten Stelleinrichtungen so ge- steuert, dass die Dichtungselemente 5 während der Aushubbewegung der an den Turabhebekopf 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 Umge- bung. 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 door lifting head 1 is advanced from the position shown in FIG. 1 to the position shown in FIG. 2 and coupled to the oven door 2 to be opened. During the forward movement, the sealing elements designed as pivotably mounted wings are spread out and assume the position II shown in FIG. 1. The coupling of the door lifting head 1 to the oven door 2 takes place in a manner known per se by hooking the lifting bar of the lifting head 1 into claws of the oven door 2. In position II, the sealing elements are pivoted back so far that the coupling process between the door lifting head 1 and the closed furnace 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 assume a working position III. In the exemplary embodiment, the contact surfaces 6 are formed on anchor stands 7. The sealing elements 5 extend essentially over the entire height of the furnace door 2 into the suction area 4 of the suction hood and form a channel-shaped suction chamber 8 for door emissions when the furnace door 2 is opened. The lifting of the furnace door out of the door opening is shown in Fig. 3. The actuating movements of the sealing elements 5 are controlled by the associated actuating devices so that the sealing elements 5 bear against the front-side contact surfaces 6 of the horizontal chamber furnace during the lifting movement of the oven door 2 coupled to the door lifting head 1 from the door opening. The illustration shows that the wing-like sealing elements 5 move on the flanges of the anchor stands 7 in the direction of the furnace door 2. The emissions emerging at the entire height of the furnace door 2 enter the suction chamber 8 and are channeled upwards in the direction of the suction hood. You cannot get into the area. Before the swing-like wing-like sealing elements 5 reach the position IV shown in FIG. 3, which corresponds to the basic position, the travel movement of the door lifting device can be briefly stopped in order to obtain a longer suction period.
Die Fig. 4 zeigt den Turabhebekopf 1 mit angekuppelter Ofentür 2 in geschwenkter Stellung vor einer nicht dargestellten Ofentürreinigungseinrichtung. Die flügelartigen Dichtungselemente 5 befinden sich in der Grundstellung I .FIG. 4 shows the door lifting head 1 with the oven door 2 coupled in the pivoted position in front of an oven door cleaning device (not shown). The wing-like sealing elements 5 are in the basic position I.
Die Fig. 5 zeigt eine weitere Ausgestaltung der erfindungs- gemäßen Vorrichtung. Die Dichtungselemente 5 sind bei dieser Ausführungsform als mehrteilige Schiebewände ausgebildet, die aus einer zurückliegenden Grundposition in einer geradlinigen Stellbewegung gegen die frontseitigen Kontaktflächen 6 des Horizontalkammerofens bewegbar sind. 5 shows a further embodiment of the device according to the invention. In this embodiment, the sealing elements 5 are designed as multi-part sliding walls, which can be moved from a previous basic position in a rectilinear actuating movement against the front contact surfaces 6 of the horizontal chamber furnace.
