Description

Die Erfindung betrifft eine Koksofentür, bestehend aus einem über Abdichtflächen gegen den Koksofenrahmen abstützbaren separaten Abdichtelement und aus einem Hohlprofilrahmen, der mit am Kammerrahmen montierten Verriegelungshaken als Widerlager verbunden ist und in dem eine Vielzahl von Stößeln verschieblich verlagert und gegen die Abdichtflächen anpreßbar sind. Bei dieser aus der EP-A-0114183 bekannten Koksofentür ist es nachteilig, daß jeder Stößel unabhängig von den anderen Stößeln angepreßt wird, wodurch unterschiedliche Anpreßdrücke an den Anpreßstellen bewirkt werden.The invention relates to a coke oven door, consisting of a separate sealing element which can be supported by means of sealing surfaces against the coke oven frame, and a hollow profile frame which is connected to locking hooks mounted on the chamber frame as an abutment and in which a large number of plungers are displaceably displaceable and can be pressed against the sealing surfaces. In this coke oven door known from EP-A-0114183, it is disadvantageous that each tappet is pressed independently of the other tappets, as a result of which different contact pressures are brought about at the contact points.

Während Koksofentüren bisher vorwiegend aus einem durchgehenden Gußkörper bestanden, werden heute Profilträger herangezogen, die zu einer geschweißten Rahmenkonstruktion für Koksofentüren verarbeitet werden. Die Dimensionierung des Hohlprofilträgers richtet sich nach statischen Erfordernissen, die durch die mechanischen und überlagerten thermischen Beanspruchungen der Türkonstruktion gekennzeichnet sind. Dem Türrahmen ist das Dichtelement vorgestellt, welches seinerseits an den Kammerrahmen zur Verbesserung der Dichtigkeit angepreßt wird.While coke oven doors previously consisted predominantly of a continuous cast body, today profile beams are used which are processed into a welded frame construction for coke oven doors. The dimensioning of the hollow profile girder is based on static requirements, which are characterized by the mechanical and superimposed thermal loads on the door construction. The door frame is presented with the sealing element, which in turn is pressed against the chamber frame to improve the tightness.

Die Anpressung kann z.B. durch Schrauben erfolgen, die durch den Hohlprofilträger gedreht auf das Dichtelement einwirken. Jede dieser Schrauben muß manuell eingestellt werden, ohne daß eine eindeutige Fixierung des Anpreßdruckes erfolgen kann, z.B. ist keine Drehmomentbegrenzung beim Anziehen der Schrauben sichergestellt. Ein weiterer gravierender Nachteil dieser bekannten Konstruktion ist die formschlüssige Verbindung zwischen dem Hohlprofilkörper und den Vorrichtungen zur Einstellung der Dichtelemente. Jede Verformung der Hohlprofilkonstruktion wirkt direkt auf diese Vorrichtung, in diesem Fall die Schrauben in ihrer Stellung zum Dichtelement ein, was den resultierenden Anpreßdruck verändert. Es ist daher erforderlich, eine Trennung von Türkörper und Vorrichtung zur Einstellung des Dichtelementes in der Kraftübertragung herbeizuführen.The pressure can be applied, for example, by screws that act on the sealing element when rotated by the hollow profile support. Each of these screws must be set manually without the contact pressure being clearly fixed, for example, no torque limitation is ensured when the screws are tightened. Another serious disadvantage of this known construction is the positive connection between the hollow profile body and the devices for adjusting the sealing elements. Any deformation of the hollow profile construction acts directly on this device, in this case the screws in their position relative to the sealing element, which changes the resulting contact pressure. It is therefore necessary to separate the door body and the device for adjusting the sealing element in the power transmission.

Die Trennung zwischen Türkörper und Dichtelement kann z.B. dadurch erreicht werden, daß innerhalb des Hohlprofilkörpers eine umlaufende Kette eingeführt wird, die alle Schrauben in gleichem Umfang für das Anpressen des Dichtelementes anzieht bzw. beim Aussetzen der Tür löst. Der Anpreßdruck kann abhängig von den Kettenumlaufzahlen eingestellt werden. Allerdings werden bei dieser Lösung alle Schrauben gleich beaufschlagt, lokale Unebenheiten auf den Kammerrahmen, z.B. durch Ablagerungen, d. h. alle Abweichungen von der Linearität werden nicht berücksichtigt. Die Vorrichtung zur Einstellung des Dichtelementes ist in diesem Fall unnachgiebig und starr; der Anpreßdruck ist daher abhängig von den örtlichen Verhältnissen an allen Stellen des Dichtelementes unterschiedlich.The separation between the door body and the sealing element can e.g. can be achieved in that a circumferential chain is inserted within the hollow profile body, which tighten all screws to the same extent for pressing the sealing element or loosens when the door is exposed. The contact pressure can be set depending on the number of chains in circulation. However, this solution applies all screws equally, local unevenness on the chamber frame, e.g. through deposits, d. H. all deviations from linearity are not taken into account. The device for adjusting the sealing element is rigid and rigid in this case; the contact pressure is therefore different at all points of the sealing element depending on the local conditions.

Der Erfindung liegt, ausgehend von einer gattungsgemäßen Koksofentür, die Aufgabe zugrunde, die Anpreßdrücke der Stößel an den einzelnen Anpreßstellen zu vergleichmäßigen und zugleich durch Hitzespannungen auftretende örtliche Verwerfungen zu vermeiden.Starting from a generic coke oven door, the invention is based on the object of comparing the contact pressures of the tappets at the individual contact points and at the same time avoiding local distortions caused by heat stresses.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Stößel mit breitflächigen Köpfen versehen sind, die sich gegen einen Druckschlauch abstützen, der umlaufend in den Längsholmen und Querholmen des Hohlprofilrahmens verlegt ist.This object is achieved in that the plungers are provided with wide-area heads which are supported against a pressure hose which is laid all around in the longitudinal spars and transverse spars of the hollow profile frame.

In den Unteransprüchen werden vorteilhafte Weiterbildungen aufgezeigt.Advantageous further developments are shown in the subclaims.

Es ist zwar bereits aus der EP-A-0063700 bekannt, Druckschläuche als kraftausgleichendes System zum Anpressen von Dichtleisten zu verwenden, wobei der Druckschlauch jedoch unmittelbar aufliegt. Bei einer unmittelbaren Auflage treten aber Probleme auf, wenn beim Andrücken Unebenheiten auszugleichen sind oder Rückstellkräfte bei örtlichen Hitzespannungen mobilisiert werden müssen, um Verwerfungen zu vermeiden.It is already known from EP-A-0063700 to use pressure hoses as a force-balancing system for pressing sealing strips, but the pressure hose lies directly on top. In the case of an immediate print run, however, problems arise if unevenness has to be compensated for when pressing on or if restoring forces have to be mobilized at local heat voltages in order to avoid distortions.

Zur Sicherung gegen Überdruck sind geeignete Überdruckventile vorzusehen. Durch die Flexibilität des Schlauches können örtliche Unebenheiten berücksichtigt werden. Bei allen Erhöhungen auf dem Kammerrahmen wird die auf die Stößel wirkende Rückstellkraft vergrößert, die Stößel werden nicht soweit vorgeschoben wie in benachbarten Bereichen, in denen die lokalen Erhöhungen auf dem Kammerrahmen nicht mehr bestehen. Somit kann mit der erfindungsgemäßen Ausführung die zweite grundlegende Forderung neben der kraftmäßigen Trennung von Türkörper und Dichtelement erzielt werden: Das Dichtelement wird an allen Stellen mit dem gleichen Anpreßdruck beaufschlagt, unabhängig von allen örtlichen Unebenheiten und Abweichungen von der Linearität. Entsprechend gut muß bei Erreichen dieses Idealzustandes die Dichtheit der Koksofentür auch nach langem Betrieb sein. Alle auch altersbedingten Abweichungen von der Linearität werden durch das flexible Anpreßsystem ausgeglichen. Jede Stelle des Dichtelementes wird über die gekoppelte Einstellung der Rückstellkraft individuell behandelt und dennoch mit dem an allen Stellen gleichem resultierenden Anpreßdruck beaufschlagt. Dieser ist in weiten Bereichen abhängig von den anlagenspezifischen Gegebenheiten individuell einstellbar.Suitable pressure relief valves must be provided to protect against excess pressure. Due to the flexibility of the hose, local unevenness can be taken into account. With all increases on the chamber frame, the restoring force acting on the tappets is increased, the tappets are not advanced as far as in adjacent areas in which the local increases on the chamber frame no longer exist. Thus, with the design according to the invention, the second basic requirement can be achieved in addition to the force-related separation of the door body and sealing element: the sealing element is subjected to the same contact pressure at all points, regardless of all local unevenness and deviations from the linearity. When this ideal condition is reached, the tightness of the coke oven door must be correspondingly good even after long operation. All age-related deviations from linearity are compensated for by the flexible pressure system. Each point of the sealing element is treated individually via the coupled setting of the restoring force and is nevertheless subjected to the resulting contact pressure which is the same at all points. This can be individually adjusted in a wide range depending on the system-specific conditions.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Darstellung ist ein Horizontalschnitt durch einen senkrecht stehenden Koksofen. Mit 1 ist der Kammerrahmen des Koksofens bezeichnet. An dem Kammerrahmen 1 liegt ein Dichtelement 2 einer Koksofentüre an. Das Dichtelement 2 besteht aus einem sich zwischen den Dichtflächen nach außen wölbenden Blech. Das Dichtelement 2 wird mittels eines Hohlprofilrahmens 3 gegen den Kammerrahmen gepreßt. Der Hohlprofilrahmen 3 besteht aus Längsholmen 4 und Querholmen 5. An den Längsholmen 4 steht der Hohlprofilrahmen 3 in nicht dargestellter Weise mit Verriegelungshaken in Eingriff, die am Kammerrahmen montiert sind. Im Hohlprofilrahmen 3 sind in gleichmäßigen Abständen umlaufend Stößel 6 verschiebbar angeordnet. Die Stößel 6 sind einfache Bolzen. Ferner ist im Hohlprofilrahmen 3 umlaufend ein Druckluftschlauch 7 vorgesehen. Alle Stößel 6 stützen sich am Druckluftschlauch 7 ab. Vorzugsweise sind die Stößel 6 dazu mit breitflächigen Köpfen 8 versehen. Der Druckluftschlauch bildet die erfindungsgemäße Anstellung der Stößel 6. Dabei wölbt sich der Druckluftschlauch in der gezeigten Betriebsstellung entsprechend dem unterschiedlichen Abstand zwischen den Seitenflanken des Dichtelementes 2 und dem Hohlprofilrahmen 3 unterschiedlich aus.In the drawing, an embodiment of the invention is shown. The illustration is a horizontal section through a vertical coke oven. With 1 the chamber frame of the coke oven is designated. A sealing element 2 of a coke oven door bears against the chamber frame 1. The sealing element 2 consists of a sheet that bulges outwards between the sealing surfaces. The sealing element 2 is pressed against the chamber frame by means of a hollow profile frame 3. The hollow profile frame 3 consists of longitudinal bars 4 and cross bars 5. On the longitudinal bars 4, the hollow profile frame 3 engages in a manner not shown with locking hooks which are mounted on the chamber frame. In the hollow profile frame 3, plungers 6 are arranged so that they can slide around at regular intervals. The plungers 6 are simple bolts. Furthermore, a compressed air hose 7 is provided all around in the hollow profile frame 3. All plungers 6 are supported on the compressed air hose 7. For this purpose, the plungers 6 are preferably provided with wide-area heads 8. The compressed air hose forms the tappet 6 according to the invention. The compressed air hose in the operating position shown bulges differently in accordance with the different distance between the side flanks of the sealing element 2 and the hollow profile frame 3.

Figur 2 zeigt einen Hohlprofilrahmen 10 anstelle des Hohlprofilrahmens 5. Im Hohlprofilrahmen 10 ist ein Zweikammerdruckluftschlauch 11 vorgesehen. Der Zweikammerdruckluftschlauch wirkt über Köpfe 12 auf Stößel 13, wobei die Köpfe 12 der Form des Druckluftschlauches 11 angepaßt sind und Rückstellfedern 14 zwischen den Köpfen 12 und dem gegenüberliegenden Teil des Kammerrahmens 10 bzw. Distanzstücken 15 vorgesehen sind.Figure 2 shows a hollow profile frame 10 instead of the hollow profile frame 5. In the hollow profile frame 10, a two-chamber compressed air hose 11 is provided. The two-chamber compressed air hose acts on the plunger 13 via heads 12, the heads 12 being adapted to the shape of the compressed air hose 11 and return springs 14 being provided between the heads 12 and the opposite part of the chamber frame 10 or spacers 15.

Der Zweikammerdruckluftschlauch 11 besitzt im Querschnitt eine runde Form mit einem in der Zeichnung zur Ebene der Dichtfläche parallel verlaufenden Steg 16. Die Zweikammerbauweise hat den Vorteil, daß im Falle einer Undichtigkeit mit der einen Kammer sofort die andere Kammer mit Druckluft beaufschlagt werden kann. Damit ist jederzeit die Dichtigkeit der Tür gewährleistet.The two-chamber compressed air hose 11 has a round shape in cross section with a web 16 running parallel to the plane of the sealing surface in the drawing. The two-chamber design has the advantage that in the event of a leak in one chamber, the other chamber can be pressurized with compressed air immediately. This ensures that the door is watertight at all times.

Vorzugsweise ist nicht nur der Kopf 12 der Schlauchform angepaßt, sondern sind auch andere mit dem Schlauch zusammenwirkenden Teile der Schlauchform angepaßt. Dies ist beispielhaft in Figur 3 dargestellt. Dort ist ein in der Berührungsfläche mit dem Schlauch 20 abgerundeter Kammerrahmen 21 vorgesehen. Der Schlauch 20 besteht im Unterschied zum Schlauch 11 aus zwei separat gefertigten Schläuchen, die im Berührungsbereich miteinander verklebt sind. Ggf. kommt auch eine Verschweißung in Betracht.Not only is the head 12 adapted to the shape of the tube, but other parts of the shape of the tube which interact with the tube are also adapted. This is shown by way of example in FIG. 3. There is a chamber frame 21 rounded in the contact area with the hose 20. In contrast to the hose 11, the hose 20 consists of two separately manufactured hoses which are glued together in the contact area. Possibly. welding is also an option.

Der mit 22 bezeichnete Stößel ist über Anschläge 23 und 24 in seiner hin- und hergehenden Bewegung begrenzt. Ferner sind mehrere Rückstellfedern 25 und 26 vorgesehen.The plunger designated 22 is limited in its reciprocating movement via stops 23 and 24. A plurality of return springs 25 and 26 are also provided.
