Eine Vorrichtung zum planieren der in die Verkokungskammer eines Koksofens eingefüllten Kohle mit unveränderbarer Räumschildbreite ist aus DE-A 23 17 685 bekannt. Die Planierstange wird in eine Planieröffnung der Ofentür ein- und ausgefahren, die aus konstruktiven Gründen deutlich schmaler ist als die Breite der Verkokungskammer. Das hat zur Folge, dass die sich bei einer oberseitigen Befüllung des Koksofens bildenden Schüttkegel zu den Kammerwänden der Verkokungskammer hin nicht gleichmäßig eingeebnet werden können. Bei einer Verkokung in Non-Recovery-Koksöfen, die mit einem flachen Kammerbesatz nach dem Verfahren der Flachbettverkokung betrieben werden, ist eine gleichmäßige Schütthöhe über die gesamte Grundfläche der Verkokungskammer erforderlich. Die bekannte Planiervorrichtung vermag die gestellten Anforderungen nicht in vollem Umfang zu erfüllen.A device for leveling the in the coking chamber of a coke oven filled coal with an unchangeable dozer blade width is from DE-A 23 17 685 known. The leveling rod is inserted into a leveling opening in the oven door extended, which for design reasons is significantly narrower than the width the coking chamber. As a result, the Filling the coke oven forming cone to the chamber walls of the Coking chamber cannot be leveled evenly. At a Coking in non-recovery coke ovens with a flat chamber to be operated according to the method of flat bed coking is one uniform dumping height over the entire base area of the coking chamber required. The known leveling device is capable of not fully meet the requirements.

Die Gleitteile bestehen aus Gleitschuhen und -rollen und gleiten in ihrer Arbeitsstellung auf schräg verlaufenden Bandabschnitten. Dadurch erhält die Planierstange an ihrem vorderen Ende eine Abstützung, die sich auf entsprechend ausgebildete Schrägflächen, die im Gassammelraum vorgesehen sind, absenkt, sobald die Planierstange sich durchbiegt. Die Planierstange ist für besonders lange Verkokungskammern geeignet. Das Kopfstück leistet zum gleichmäßigen Einebnen der Kohle keinen Beitrag.In a leveling device known from DE-A 32 45 552 Dozer head with a head at its front end, the two at Includes articulated levers sliding parts using a Actuator from a rest position, in which the sliding parts within of the head piece, pivotable into a working position by spreading are. The sliding parts consist of sliding shoes and rollers and slide in their Working position on sloping belt sections. This gives the Bulldozer at its front end a support that is on appropriately trained inclined surfaces provided in the gas collecting space are lowered as soon as the leveling rod bends. The bulldozer is suitable for particularly long coking chambers. The headpiece contributes to even leveling of coal makes no contribution.
Eine Vorrichtung mit den eingangs beschriebenen Merkmalen ist in der Druckschrift DE 279 307 C beschrieben. Bei der bekannten Vorrichtung sind die Schaufeln des Räumschildes auf einem Gleitstück angebracht und in Querrichtung verschiebbar gelagert.A device with the features described above is in the Document DE 279 307 C described. In the known device Scoops of the dozer blade attached to a slide and in Transversely supported.
Der Erfindung liegt die Aufgabe zugrunde, eine Planiervorrichtung anzugeben, mit der Schüttkegel in der Verkokungskammer sehr gleichmäßig bis zu den Kammerwänden hin eingeebnet werden können.The invention has for its object to provide a leveling device with the pouring cone in the coking chamber very evenly up to the Chamber walls can be leveled out.
Ausgehend von einer Vorrichtung mit den eingangs beschriebenen Merkmalen wird die Aufgabe erfindungsgemäß dadurch gelöst, dass das Räumschild aus zwei an dem vorderen Ende der Planierstange schwenkbar angeordneten Flügeln besteht, die bei der Ein- und Ausfahrbewegung durch die Planieröffnung an der Planierstange pflugförmig anliegen und in der Verkokungskammer durch eine Stellbewegung der Betätigungseinrichtung ausklappbar sind und dass die Innenflächen des Räumschildes zu der Außenfläche des Räumschildes unter einem spitzen Winkel angeordnet sind, wobei der Scheitelpunkt des Winkels sich jeweils am äußeren Ende des Räumschildes befindet und wobei Winkel so gewählt ist, dass Kohle bei einer Rückwärtsbewegung der Planierstange von dem ausgestellten Räumschild zu seitlichen Ofenwänden verdrängt wird. Die maximale Spannbreite entspricht vorzugsweise in etwa der Kammerbreite der Verkokungskammer. Mittels der Betätigungseinrichtung kann die wirksame Räumfläche erheblich verbreitert werden, nachdem die Planierstange in die Verkokungskammer eingefahren ist. Dies erlaubt ein effektives Arbeiten und gleichmäßiges Planieren. Starting from a device with the features described above the object is achieved in that the dozer blade two pivotally arranged at the front end of the leveling bar There are wings that when entering and exiting through the Fit the leveling opening on the leveling plow and in the Coking chamber through an actuating movement of the actuating device are foldable and that the inner surfaces of the dozer blade to the The outer surface of the dozer blade is arranged at an acute angle, where the apex of the angle is at the outer end of the Is located and where angle is chosen so that coal at a The dozer blade moves backward from the clearing blade on display side furnace walls is displaced. The maximum range corresponds preferably approximately the chamber width of the coking chamber. By means of the Actuator can significantly broaden the effective clearing area after the leveling rod has entered the coking chamber. This allows effective work and even leveling.
Während der rückwärts gerichteten Planierbewegung der Planierstange sind die Flügel des Räumschildes ausgeschwenkt und hat das Räumschild seine größte Spannbreite. Durch die beschriebene Profilierung der Flügel wird ein pflugförmiges Räumprofil erzeugt, das Kohle, die an den Rändern der bereits eingeebneten Fläche noch Schüttkegel bilden, zu den seitlichen Ofenwänden der Verkokungskammer hin fördert. Die Rückfahrt der Planierstange wird erst kurz vor Erreichen der Ofentür gestoppt. Dadurch wird erreicht, dass die Kohleschüttung bis in die Eckbereiche der Verkokungskammer gleichmäßig eingeebnet wird. Anschließend wird die Planierstange in Vorwärtsrichtung soweit bewegt, dass die Flügel des Räumschildes zurückgeschwenkt werden können. Nachdem das Räumschild seine Grundstellung eingenommen hat und die Flügel pflugförmig an der Planierstange anliegen, wird die Planierstange aus der Verkokungskammer herausgefahren und ist der Planiervorgang beendet.During the backward leveling movement of the leveling bar are the Wings of the dozer blade swung out and the dozer blade has its largest Span. The described profile of the wing is a plow-shaped clearing profile that produces coal that is on the edges of the already leveled surface still form cones of bulk, to the side furnace walls promotes the coking chamber. The return of the leveling bar is only stopped shortly before reaching the oven door. This ensures that the Coal fill evenly into the corner areas of the coking chamber is leveled. Then the leveling bar moves in the forward direction moved so far that the wings of the dozer blade are swung back can. After the dozer blade has assumed its basic position and the wings plow-like against the leveling bar, the leveling bar is out out of the coking chamber and the leveling process is finished.
Die Flügel sind jeweils mit einem Hebel gelenkig an eine Stellstange angeschlossen, die in der Planierstange, z. B. an Tragrollen, axial verschiebbar gelagert und an ihrem rückwärtigen Ende an eine Stelleinrichtung angeschlossen ist. Die Stelleinrichtung kann aus einer hydraulischen Zylinder/Kolbenanordnung bestehen.The wings are each articulated to a control rod with a lever connected, which in the leveling rod, for. B. on idlers, axially displaceable stored and at its rear end to an actuator connected. The actuator can be made of a hydraulic Cylinder / piston arrangement exist.
In der Grundstellung sind die Flügel pflugförmig nach innen geschwenkt. Das ermöglicht den Durchtritt der Anordnung durch die im Vergleich zur Breite der Verkokungskammer wesentlich schmalere Planieröffnung. Während der Vorwärtsfahrt der Planierstange wird die Grundstellung des Räumschildes beibehalten. Die nach innen geschwenkten und pflugförmig ausgerichteten Flügel fördern während der Vorwärtsfahrt der Planierstange in die Verkokungskammer die Kohle von der Kammermitte weg in Richtung der seitlichen Ofenwände. Nachdem die Planierstange bis zum Ende der Verkokungskammer durchgefahren ist, wird die Stellstange ausgefahren, wobei die Flügel über die Hebelanordnung soweit vorgeschwenkt werden, bis die Außenfläche des aufgespreizten Räumschildes im Wesentlichen parallel zu der der Planieröffnung gegenüberliegenden Ofenwand ausgerichtet ist. Dabei verbreitert sich die Raumfläche. Ferner wird durch die Schwenkbewegung der Flügel Kohle in die Eckbereiche der Verkokungskammer verteilt.In the basic position, the wings are turned in a plow shape. The allows the passage of the arrangement through compared to the width of the Coking chamber much narrower leveling opening. During the Forward movement of the leveling bar becomes the basic position of the dozer blade maintained. The pivoted inward and plow-shaped The blades feed into the dozer while the bulldozer is moving forward Coking chamber the coal away from the center of the chamber towards the side furnace walls. After the leveling bar to the end of the Coking chamber has passed, the control rod is extended, whereby the wings are swung forward over the lever arrangement until the Outer surface of the spreading blade substantially parallel to the the leveling opening opposite the furnace wall is aligned. there the space expands. Furthermore, the pivoting movement of the Wing coal spread in the corner areas of the coking chamber.
