Definitions

  • the invention relates to a coke oven door, consisting of a separate sealing element which can be supported by means of sealing surfaces against the coke oven frame, and a hollow profile frame which is connected to locking hooks mounted on the chamber frame as an abutment and in which a large number of plungers are displaceably displaceable and can be pressed against the sealing surfaces.
  • a coke oven door known from EP-A-0114183, it is disadvantageous that each tappet is pressed independently of the other tappets, as a result of which different contact pressures are brought about at the contact points.
  • the pressure can be applied, for example, by screws that act on the sealing element when rotated by the hollow profile support.
  • 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 tighten all screws 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, d. H. all deviations from linearity are not taken into account.
  • the device for adjusting the sealing element is rigid and rigid in this case; the contact pressure is therefore different at all points of the sealing element depending on the local conditions.
  • the invention is based on the object of comparing the contact pressures of the tappets at the individual contact points and at the same time avoiding local distortions caused by heat stresses.
  • the plungers are provided with wide-area heads which are supported against a pressure hose which is laid all around in the longitudinal spars and transverse spars of the hollow profile frame.
  • Suitable pressure relief valves must be provided to protect against excess pressure. Due to the flexibility of the hose, local unevenness can be taken into account. With all increases on the chamber frame, the restoring force acting on the tappets is increased, the tappets are not advanced as far as in adjacent areas in which the local increases on the chamber frame no longer exist.
  • the second basic requirement can be achieved in addition to the force-related separation of the door body and sealing element: the sealing element is subjected to the same contact pressure at all points, regardless of all local unevenness and deviations from the linearity. When this ideal condition is reached, the tightness of the coke oven door must be correspondingly good even after long 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 pressed against the chamber frame by means of a hollow profile frame 3.
  • 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 on the plunger 13 via heads 12, 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 shape in cross section with a web 16 running parallel to the plane of the sealing surface in the drawing.
  • the two-chamber design has the advantage that in the event of a leak in one chamber, the other chamber can be pressurized with compressed air 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.
