Definitions

  • the invention relates to a coke oven door according to the preamble of claim 1.
  • 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 limbs 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
  • 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.
  • 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 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.
  • a door lock for horizontal coking chamber furnaces with an elastic, covering the door gap can be pressed against the door frame and known from metal sealing frames, elastic pressure elements acting on the edge of the sealing frame being arranged directly at the door body. These pressure media consist of leaf springs. Larger deformations between the door body and door frame can compensate for this sealing system only to a limited extent, since then the sealing frame would have to be bent very far with the sealing cutting edge and the sealing cutting edge would in particular no longer stand up vertically on the sealing surface of the frame.
  • 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.
  • the sealing element which consists of a conventional sealing edge or a soft seal or similar proven elements, is one of the free end on the door body pressed in the longitudinal direction of the furnace directly or indirectly fixed leaf spring against the door frame.
  • the leaf springs are characterized as a particularly simple and inexpensive construction element. Overall, fewer individual parts and in particular no complex mechanically moving parts are required.
  • 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.
  • 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.
  • 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.
  • the construction according to the invention is particularly suitable for retrofitting existing door seals with z. B. Z sealing strips.
  • FIG. 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.
  • the clamping plate (4) is fastened to the coke oven door (1) with the fastening screws (5).
  • 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.
  • 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).
  • 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).
  • 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).
  • 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).
