Definitions

  • 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 carries 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 by means of the door body attached leaf springs is pressed against the door frame, according to the main patent P 39 13 247.
  • the main patent specifies various designs for leaf springs attached to the clamping plates. 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.
  • the object of the present invention is therefore to improve the shape and arrangement of the leaf spring with a view to less expensive production and its effectiveness.
  • the leaf spring attached to the clamping plate consists of a flat, optionally pre-bent flat spring.
  • flat flat springs can be used, which can optionally 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 right angles or in a T-shape on the clamping plate.
  • the contact pressure exerted by the flat spring on the sealing cutting edge is particularly effective and precisely definable when the leaf spring attached to the holding bracket consists of a flat spring extending in the longitudinal direction of the sealing cutting edge and when the leaf spring is attached centrally to the holding bracket 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.
  • FIGS. 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.
  • 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 retaining bracket (15) is arranged at right angles to the clamping plate (4) and parallel to the sealing surface of the door frame (3), which is expediently welded or otherwise firmly connected to the clamping plate.
  • the leaf spring (8) designed as a flat flat spring is arranged parallel to the sealing cutting edge (13).
  • 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).
  • FIGS. 3 and 4 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).
  • both the leaf springs (8) and (8a) can be arranged all around the door body in a specific order.
