Definitions

  • the invention relates to a coke oven door with a separate sealing element, which is pressed against the chamber frame by a hollow profile frame by means of a plurality of adjusting devices arranged all around the sealing element in the region of the sealing surface.
  • the pressure can be applied, for example, by screws which act on the sealing element when rotated by the hollow profile carrier.
  • 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.
  • 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 all screws tighten 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, i.e. all deviations from linearity are not taken into account.
  • the device for adjusting the sealing element is unyielding and rigid; the contact pressure is therefore different at all points of the sealing element depending on the local conditions.
  • the invention is therefore based on the object not only to enable the separation of forces between the door body and the sealing element, but to allow the individual adjustment of each individual pressing device.
  • a circumferential hose is arranged in the hollow profile door frame, which is inflated after the door is inserted and, if necessary, is acted upon with suitable cooling media (for example from the printing press). With inflation, the plungers guided through the frame onto the sealing element are pressed onto the sealing element.
  • suitable cooling media for example from the printing press.
  • the pressure hose can also be placed directly on the sealing element or the chamber frame itself. This arrangement presupposes that the pressure hose is either thermally resistant and / or the heat acting on it is dissipated in a targeted manner (for example by partially filling the hose with water or other liquid or gaseous) Media).
  • Suitable pressure relief valves must be provided to protect against excess pressure.
  • the sealing element is subjected to the same contact pressure at all points, regardless of all local unevenness and deviations from the linearity.
  • the tightness of the coke oven door must be correspondingly good even after a long period of 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.
  • FIG. 1 An embodiment of the invention is shown.
  • the illustration is a horizontal section through a vertical coke oven.
  • the chamber frame of the 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 ge by means of a hollow profile frame 3 against the chamber frame presses.
  • 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.
  • plungers 6 are arranged so that they can slide around at regular intervals.
  • the plungers 6 are simple bolts.
  • 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.
  • Figure 2 shows a hollow profile frame 10 instead of the hollow profile frame 5.
  • a two-chamber compressed air hose 11 is provided in the hollow profile frame 10.
  • the two-chamber compressed air hose acts via heads 12 on plunger 13, 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.
  • the two-chamber compressed air hose 11 has a round cross-section with a web 16 running parallel to the plane of the sealing surface in the drawing.
  • the two-chamber construction has the advantage that in the event of a leak in one chamber, the other chamber can be pressurized immediately. This ensures that the door is watertight at all times.
  • 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.
  • the hose 20 consists of two separately manufactured hoses which are glued together in the contact area. Possibly. welding is also an option.
  • 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.
