Description

Die Erfindung bezieht sich auf eine Koksofentür gemäß Oberbe­griff des Anspruches 1.The invention relates to a coke oven door according to the preamble of claim 1.

Eine derartige Koksofentür ist aus der DE-PS 23 09 032 be­kannt. Hierbei ist das elastische Dichtelement als umlaufendes Winkelprofil gestaltet, das mit einem Schenkel am Türkörper gehalten ist und dessen anderer freier Schenkel die am Türrah­men zur Auflage kommende, unter Einwirkung federbelasteter Druckbolzen stehende Schneide trägt. Zur Halterung des Dicht­elementes dienen über den Türumfang verteilte Klemmplatten, die am Türkörper mittels Schrauben befestigt sind und, ebenso wie die durch Klemmdruck gehaltenen Schenkel des Dichtelemen­tes, in Längsrichtung der Ofenkammer verstellbar sind und wo­bei die Klemmplatten im wesentlichen parallel zur Auflageflä­che der Schneide am Türrahmen stehende Führungsplatten mit Bohrungen besitzen, in denen zur Einwirkung auf die Dicht­schneide kommende federbelastete Bolzen geführt sind. Die Konstruktion dieser federbelasteten Klemmplatte ist relativ aufwendig. Das gilt vor allem für die zwischen den Führungs­platten anzuordnenden Druckfedern.Such a coke oven door is known from DE-PS 23 09 032. Here, the elastic sealing element is designed as a circumferential angle profile, which is held on the door body with one leg and the other free leg of which carries the cutting edge which comes into contact with the door frame and is under the action of spring-loaded pressure bolts. Clamping plates distributed over the door circumference serve to hold the sealing element, which are fastened to the door body by means of screws and, like the legs of the sealing element held by clamping pressure, are adjustable in the longitudinal direction of the furnace chamber and the clamping plates are essentially parallel to the contact surface of the cutting edge on the door frame Have guide plates with holes in which spring-loaded bolts coming to act on the sealing cutting edge are guided. The construction of this spring-loaded clamping plate is relatively complex. This applies above all to the compression springs to be arranged between the guide plates.

Die elastische Dichtmembran kann auch als sich über die gesam­te Breite und Länge erstreckende Membranplatte ausgebildet sein, die gelenkig am Türkörper befestigt und abstandsverän­ derlich gegenüber diesem angeordnet sein kann (vgl. DE-OS 33 27 337). Die Dichtelemente werden hierbei über Druckschrauben und gegebenenfalls mit zusätzlichen Schraubenfedern gegen den Türrahmen gepreßt. Auch diese Art der Anpressung der Dichtele­mente ist aufwendig und störanfällig.The elastic sealing membrane can also be designed as a membrane plate extending over the entire width and length, which is articulated to the door body and variable in distance which can be arranged opposite this (see. DE-OS 33 27 337). The sealing elements are pressed against the door frame using pressure screws and, if necessary, with additional coil springs. This type of pressing of the sealing elements is also complex and prone to failure.

Aufgabe der Erfindung ist es nun, eine gattungsgemäße Koks­ofentür mit einer elastischen Dichtmembrane vorzuschlagen, bei dem das Andrucksystem für die Dichtelemente verbessert wird und die vorgenannten Probleme nicht auftreten.The object of the invention is now to propose a generic coke oven door with an elastic sealing membrane, in which the pressure system for the sealing elements is improved and the aforementioned problems do not occur.

Zur Lösung dieser Aufgabe werden die im Kennzeichen des An­spruches 1 angegebenen Merkmale vorgeschlagen. Die Unteran­sprüche 2 bis 6 enthalten sinnvolle Ergänzungen dazu.To achieve this object, the features specified in the characterizing part of claim 1 are proposed. Subclaims 2 to 6 contain useful additions.

Erfindungsgemäß wird das Dichtelement, das aus einer üblichen Dichtschneide oder einer Weichdichtung oder ähnlichen bewähr­ten Elementen besteht, mit Hilfe von am Türkörper in Ofen­längsrichtung mittelbar oder unmittelbar verstellbar befestig­ten Blattfedern gegen den Türrahmen gepreßt. Die Blattfedern zeichnen sich im Gegensatz zu den bisher üblichen Schraubenfe­dern als besonders einfaches und kostengünstiges Konstruk­tionselement aus. Insgesamt werden weniger Einzelteile und insbesondere keine aufwendigen mechanisch beweglichen Teile benötigt.According to the invention, the sealing element, which consists of a conventional sealing edge or a soft seal or similar tried and tested elements, is pressed against the door frame with the aid of leaf springs which are indirectly or directly adjustably attached to the door body in the longitudinal direction of the furnace. In contrast to the conventional coil springs, the leaf springs are particularly simple and inexpensive. Overall, fewer individual parts and in particular no complex mechanically moving parts are required.

Zur Einstellung der Anpreßkraft gegen den Türrahmen ist erfin­dungsgemäß weiterhin an dem freien Ende der Blattfeder eine auf die Oberkante des Dichtelementes in Richtung auf den Tür­rahmen wirkende Stellschraube vorgesehen. Zweckmäßig wird die Blattfeder bereits bei der Montage mit einer gewissen Vorspan­nung gegen das Dichtelement gepreßt und im eingebauten Zustand die endgültig erforderliche Anpreßkraft durch Verstellung der Stellschrauben eingestellt.To adjust the contact pressure against the door frame, an adjusting screw acting on the upper edge of the sealing element in the direction of the door frame is further provided according to the invention at the free end of the leaf spring. The leaf spring is expediently pressed against the sealing element during assembly with a certain pretension and, in the installed state, the final pressing force is adjusted by adjusting the adjusting screws.

Die elastische Dichtmembran, an der das Dichtelement befestigt ist, kann z. B. aus einem ebenen oder profilierten Dichtblech bestehen. Es hat sich insbesondere als günstig erwiesen, sie als Z-Profil auszubilden und gemeinsam mit den Blattfedern mit Klemmplatten am Türkörper derartig zu befestigen, daß Blattfe­dern und Klemmplatten gleichzeitig in Ofenlängsrichtung ver­stellbar sind. Die Blattfedern können zweckmäßig mehrlagig, eventuell mit unterschiedlicher Länge ausgeführt sein. Günstig ist vor allem eine rechtwinklige Form der Blattfeder, wobei ein Ende an der Klemmplatte bzw. zwischen Klemmplatte und Tür­körper befestigt ist und das andere Ende auf das Dichtelement in Richtung auf den Türrahmen Federkräfte ausübt. Daneben kann die Blattfeder in Hinblick auf eine Erhöhung des möglichen Fe­derweges auch zusätzlich S- oder Z-förmig gebogen sein. Die Blattfedern können entweder mit den Klemmplatten gemeinsam oder auch unabhängig davon auswechselbar sein.The elastic sealing membrane to which the sealing element is attached can, for. B. from a flat or profiled sealing plate consist. It has proven to be particularly advantageous to design them as a Z-profile and to fasten them together with the leaf springs with clamping plates to the door body in such a way that leaf springs and clamping plates are simultaneously adjustable in the longitudinal direction of the furnace. The leaf springs can expediently be multilayered, possibly with different lengths. Above all, a rectangular shape of the leaf spring is favorable, with one end being fastened to the clamping plate or between the clamping plate and the door body and the other end exerting spring forces on the sealing element in the direction of the door frame. In addition, the leaf spring can also be bent in an S or Z shape with a view to increasing the possible spring travel. The leaf springs can be exchangeable either together with the clamping plates or independently.

Die erfindungsgemäße Konstruktion eignet sich insbesondere für die Umrüstung von vorhandenen Türdichtungen mit z. B. Z-Dicht­leisten.The construction according to the invention is particularly suitable for retrofitting existing door seals with z. B. Z sealing strips.

Die Erfindung wird anhand der beigefügten Figuren 1 bis 3 bei­spielsweise näher erläutert.The invention is explained in more detail, for example, with the aid of the attached FIGS. 1 to 3.

Die Klemmplatte (4) ist, wie aus Figur 2 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. In der Mitte zwischen den beiden Befestigungs­schrauben (5) ist mit der Befestigungschraube (17) die erfin­dungsgemäße Blattfeder (8) an der Klemmplatte (4) befestigt. Die Blattfeder (8) ist rechtwinklig ausgebildet und mit dem einen Schenkel (15) mit der Klemmplatte (4) verbunden. Der an­dere freie Schenkel ist im wesentlichen parallel zur Dichtflä­che des Türrahmens (3) angeordnet. An dessen freiem Ende ist mit einer Kontermutter (9) eine Stellschraube (16) angeordnet, mit deren Hilfe die auf die Dichtscheide (13) ausgeübte An­preßkraft einstellbar ist. Der mögliche Verstellweg der Klemm­platte (4) ist in Figur 1 durch die Pfeile (14) angezeigt. Um eine gleichzeitige Verstellung des Z-Profiles (2) der Blattfe­der (8) mit der Klemmplatte (4) zu erreichen und für eine aus­reichende Rückstellsicherung sind an der Klemmplatte (4) der Anschlag (10) für die Blattfeder und der Anschlag (11) für den Schenkel (12) der Dichtleiste (2) vorgesehen.Figure 1 shows the arrangement of a conventional Z-bar (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 using the clamping plate (4) by clamping pressure. As can be seen in FIG. 2, 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 the middle between the two fastening screws (5), the leaf spring (8) according to the invention is fastened to the clamping plate (4) with the fastening screw (17). The leaf spring (8) is rectangular and is connected with one leg (15) to the clamping plate (4). The other free leg is arranged essentially parallel to the sealing surface of the door frame (3). At its free end is with a lock nut (9) an adjusting screw (16) is arranged, with the aid of which the contact pressure exerted on the sealing sheath (13) can be adjusted. The possible adjustment path of the clamping plate (4) is indicated in Figure 1 by the arrows (14). In order to achieve a simultaneous adjustment of the Z-profile (2) of the leaf spring (8) with the clamping plate (4) and for adequate reset protection, the stop (10) for the leaf spring and the stop (11) are on the clamping plate (4). provided for the leg (12) of the sealing strip (2).

In der Figur 3 ist eine andere Ausführungsform einer Blattfe­der (8a) dargestellt, die mit dem Schenkel (15a) an der Klemm­platte bzw. dem Türkörper verstellbar verbunden ist. Durch den zusätzlichen Bogen der Klemmplatte (8a) kann ein höherer Fe­derweg und damit gegebenenfalls eine dauernde Anpressung gegen das Dichtelement (13) gewährleistet werden.FIG. 3 shows another embodiment of a leaf spring (8a) which is adjustably connected to the leg (15a) on the clamping plate or the door body. The additional bend of the clamping plate (8a) ensures a higher spring travel and thus possibly a permanent pressure against the sealing element (13).
