Description
Die Erfindung bezieht sich auf eine Koksofentür mit einer elastischen Dichtmembran, die am Türkörper, vorzugsweise in Ofenlängsrichtung verstellbar, befestigt ist und deren freier Schenkel das umlaufende, am Türrahmen zur Auflage kommende federbelastete Dichtelement tragt, wobei das Dichtelement mit Hilfe von am Türkörper in Ofenlängsrichtung verstellbar befestigten Klemmplatten und damit verbundenen Blattfedern gegen den Türrahmen gepreßt wird.The invention relates to a coke oven door with an elastic sealing membrane, which is fastened to the door body, preferably adjustable in the longitudinal direction of the oven, and whose free leg bears the circumferential spring-loaded sealing element which comes to rest on the door frame, the sealing element being adjustable in the longitudinal direction of the oven with the aid of the door body attached clamping plates and associated leaf springs is pressed against the door frame.
In der DE-C-39 13 247 sind verschiedene Konstruktionen fur an den Klemmplatten befestigte Blattfedern angegeben. Diese Blattfedern sollen dabei in besonderer Weise profiliert sein und z. B. rechtwinklig oder S- oder Z-formig ausgebildet sein. Die Fertigung dieser Blattfedern ist nicht immer einfach.In DE-C-39 13 247 various constructions for leaf springs attached to the clamping plates are specified. These leaf springs should be profiled in a special way and z. B. be rectangular or S or Z-shaped. The manufacture of these leaf springs is not always easy.
Aufgabe der vorliegenden Erfindung ist es also, die Form und Anordnung der Blattfeder in Hinblick auf eine kostengünstigere Fertigung und ihre Wirksamkeit zu verbessern.The object of the present invention is therefore to improve the shape and arrangement of the leaf spring with a view to cheaper production and its effectiveness.
Zur Lösung dieser Aufgabe wird vorgeschlagen, daß die Blattfeder aus einer ebenen, gegebenenfalls im entlasteten Zustand vorgebogenen Flachfeder besteht, die an einem rechtwinklig oder T-förmig an der Klemmplatte angeordnete Haltebügel oder Ansatz befestigt ist.To solve this problem it is proposed that the leaf spring consists of a flat, optionally pre-bent in the unloaded flat spring, which is attached to a bracket or extension arranged at right angles or in a T-shape on the clamping plate.
Es hat sich gezeigt, daß einfache und preisgünstige ebene Flachfedern verwendet werden konnen, die gegebenenfalls so vorgebogen sein können, daß sie im eingebauten Zustand bei Anpressung gegen die Dichtschneide möglichst vollständig eben ausgebildet sind. Die Plattfedern werden zweckmäßig mit einer Schraubverbindung an einem rechtwinklig oder T-förmig an der Klemmplatte angeordneten Haltebügel oder Ansatz befestigt. Die Anpreßkraft, die von der Flachfeder auf die Dichtschneide ausgeübt wird, ist dann besonders wirksam und genau definierbar, wenn die am Haltebügel befestigte Blattfeder aus einer sich in Längsrichtung der Dichtschneide erstreckenden Flachfeder besteht und wenn die Blattfeder mittig am Haltebügel befestigt ist und die Anpreßkräfte über die Enden der Blattfeder auf die Dichtschneide einwirken. Die Anpreßkraft der Blattfedern ist dabei abhängig von dem Querschnitt der Flachfeder und von dem Abstand der Befestigung am Haltebügel zum Angriffspunkt am Ende der Flachfeder und kann durch Veränderung dieser Parameter auf einfache Weise eingestellt werden. Die Flachfedern können aufgrund ihrer Befestigung über Schraubverbindungen auch während des laufenden Betriebes problemlos und schnell ausgewechselt werden.It has been shown that simple and inexpensive level Flat springs can be used, if necessary can be pre-bent so that they are as completely flat as possible in the installed state when pressed against the sealing cutting edge. The flat springs are expediently fastened with a screw connection to a holding bracket or extension arranged at a right angle or in a T-shape on the clamping plate. The contact pressure exerted by the flat spring on the sealing blade is particularly effective and precisely definable if the leaf spring attached to the retaining clip consists of a flat spring extending in the longitudinal direction of the sealing blade and if the leaf spring is attached centrally to the retaining clip and the contact pressure is above act on the ends of the leaf spring on the sealing blade. The contact pressure of the leaf springs depends on the cross section of the flat spring and on the distance from the attachment on the bracket to the point of application at the end of the flat spring and can be easily adjusted by changing these parameters. The flat springs can be replaced quickly and easily during operation due to their fastening using screw connections.
Die Erfindung wird anhand der beigefügten Figuren 1 bis 4 beispielsweise näher erläutert.The invention is explained in more detail, for example, with reference to the attached FIGS.
Die Figuren 1 und 3 zeigen die Anordnung einer üblichen Z-Dichtleiste (2) mit der Dichtschneide (13) am Türkörper einer Koksofentür (1). Die Z-Leiste (2) wird mit dem einen Schenkel (12) am Türkörper mit Hilfe einer Klemmplatte (4) durch Klemmdruck gehalten. Die Klemmplatte (4) ist, wie aus den Figuren 2 und 4 ersichtlich, mit den Befestigungsschrauben (5) an der Koksofentür (1) befestigt. Mit Hilfe der am Ansatz (7) am Türkörper (1) befestigten Verstellschraube (6) kann die Klemmplatte in Ofenlängsrichtung verstellt werden.Figures 1 and 3 show the arrangement of a conventional Z-sealing strip (2) with the sealing edge (13) on the door body of a coke oven door (1). The Z-bar (2) is held with one leg (12) on the door body by means of a clamping plate (4) by clamping pressure. As can be seen from FIGS. 2 and 4, the clamping plate (4) is fastened to the coke oven door (1) with the fastening screws (5). With the help of the adjusting screw (6) attached to the extension (7) on the door body (1), the clamping plate can be adjusted in the longitudinal direction of the furnace.
In der Mitte zwischen den beiden Befestigungsschrauben ist nach den Figuren 1 und 2 rechtwinklig zur Klemmplatte (4) und parallel zur Dichtfläche des Türrahmens (3) der Haltebügel (15) angeordnet, der mit der Klemmplatte zweckmäßigerweise verschweißt oder in sonstiger Weise fest verbunden ist. Am Ende des Haltebügels (15) ist parallel zur Dichtschneide (13) laufend die als ebene Flachfeder ausgebildete Blattfeder (8) angeordnet. An den freien Enden dieser Blattfeder (8) sind, wie auch aus der Hauptanmeldung ersichtlich, die Stellschraube (16) mit der Kontermutter (9) zur Übertragung der einstellbaren Anpreßkräfte angeordnet. Der mögliche Verstellweg der Klemmplatte (4) ist in den Figuren 1 und 3 durch die Pfeile (14) angezeigt.In the middle between the two fastening screws, according to FIGS. 1 and 2, the retaining bracket (15) is arranged at right angles to the clamping plate (4) and parallel to the sealing surface of the door frame (3) is welded or otherwise firmly connected. At the end of the holding bracket (15), the leaf spring (8) designed as a flat flat spring is arranged parallel to the sealing cutting edge (13). At the free ends of this leaf spring (8), as can also be seen from the main application, the adjusting screw (16) with the lock nut (9) for transmitting the adjustable contact forces is arranged. The possible adjustment path of the clamping plate (4) is indicated in FIGS. 1 and 3 by the arrows (14).
Um eine gleichzeitige Verstellung des Z-Profiles (2) der Blattfedern (8), (8a) mit der Klemmplatte (4) zu erreichen und für eine ausreichende Rückstellsicherung, ist an der Klemmplatte (4) der Anschlag (11) für den Schenkel (12) der Dichtleiste (2) vorgesehen.In order to achieve a simultaneous adjustment of the Z-profile (2) of the leaf springs (8), (8a) with the clamping plate (4) and for a sufficient reset protection, the stop (11) for the leg ( 12) of the sealing strip (2).
In den Figuren 3 und 4 ist im Vergleich zu den Figuren 1 und 2 eine andere Blattfeder (8a) dargestellt. Diese ist über die Schraube (17) am mit der Klemmplatte (4) verbundenen Ansatz (10) verschraubt und drückt mit ihrem freien Ende über die Stellschraube (16) gegen die Dichtschneide (13). Die Blattfeder (8a) besitzt jeweils nur einen Anpreßpunkt, während die Blattfedern (8) nach den Figuren 1 und 2 an beiden Enden auf die Dichtschneide (13) drücken. Entsprechend den Platzverhältnissen können am Türkörper umlaufend sowohl die Blattfedern (8) als auch (8a) in bestimmter Reihenfolge angeordnet sein.Another leaf spring (8a) is shown in FIGS. 3 and 4 compared to FIGS. 1 and 2. This is screwed via the screw (17) to the attachment (10) connected to the clamping plate (4) and presses with its free end via the adjusting screw (16) against the sealing cutting edge (13). The leaf spring (8a) has only one contact point, while the leaf springs (8) according to Figures 1 and 2 press on both ends of the sealing cutting edge (13). Depending on the space available, both the leaf springs (8) and (8a) can be arranged all around the door body in a specific order.
