Definitions

  • the invention relates to a coke oven door according to the preamble of claim 1.
  • a coke oven door according to the preamble of claim 1 is known from DE-C-915 564.
  • the sealing element is in this case formed by a Z-shaped or S-shaped sealing frame made of profiled iron, which forms a cutting-like sealing strip on the outer circumference and which is adjustably attached to the edge of the door body by means of eccentric discs.
  • Coke oven doors are also known (US-A-2 200 403 and DE-C-913 764), in which angular rigid sealing strips, which are carried by a flexible metal sheet or by the deformable edge of a plate, are pressed by means of set screws on the door frame.
  • the prior art also includes a coke oven door with a circumferential sealing edge (DE-B-22 29 953), in which, in addition to the sealing edge, a sheet of highly elastic spring steel is arranged, which is held in place with the sealing edge by hook screws on the leg of the door body.
  • a coke oven door is also known (DE-A-3 024 547), in which the sealing frame contains a sealing groove into which a sealing compound is filled.
  • the invention is therefore based on the object, avoiding these disadvantages, to design a coke oven door of the type required in the preamble of claim 1 in such a way that, despite the simple construction, a perfect seal is ensured even after the door has been closed.
  • This object is achieved by the characterizing features of claim 1.
  • the coke oven door only partially illustrated in the drawing contains a door body 1, a door stopper 2 and a door stopper support 3.
  • the connection between the door body 1 and the door stopper support 3 is explained in detail with reference to FIG. 3.
  • Tensioning and locking devices are used to tension and lock the door body 1 with respect to a fixed door frame 4.
  • Fig. 3 illustrates the adjustable connection between the door body 1 and the door plug support 3.
  • the door body 1 is provided with an adjustment bracket 5 (a limited number of such adjustment brackets 5 are of course provided over the entire circumference of the coke oven door).
  • a spindle 6 can be adjusted in the longitudinal direction by means of a first threaded section 6a.
  • a second threaded section 6b of the spindle 6, which has a different thread pitch than the threaded section 6a there is a holding piece 7, which engages around a driver 8 with a T-shaped cross section at its lower end. This driver 8 is firmly connected to the door plug support 3.
  • the spindle 6 If the spindle 6 is rotated, it carries out a longitudinal displacement in the adjusting block 5. The different thread pitch of the threaded sections 6a and 6b moves
  • the door body 1 is provided with a leveling opening 9 which can be closed by a leveling lock (not shown).
  • a corresponding leveling opening 10 or 11 is also located in the door plug support 3 and in the door plug 2.
  • an elastic compensator 12 is provided, which is connected by screws 13 and 14 on the one hand to the door body 1 and on the other hand to the door plug support 3.
  • a protective tube 15 which, for example, is firmly connected to the door body 1 and is slidable relative to the door plug 2 and the door plug carrier 3.
  • a sealing element 17 is used which runs around the entire circumference of the coke oven door and is rounded at the corners metallic membrane 19.
  • This membrane 19 is clamped on its inner edge by means of the screws 14 already mentioned on the door plug support 3 and carries the sealing strip 18 on its outer edge. Sealing strip 18 and membrane 19 are expediently formed in one piece.
  • the membrane 19 is shaped in such a way (vaulted like a lid) that when the sealing strip 18 is pressed onto the door frame 4, with the membrane 19 being elastically deformed, there is a wedge-shaped gap 20 which opens outwards (angles a, see FIG. 2 ).
  • the sealing strip 18 moves outwards, i.e. In the direction of arrow 21 in FIG. 2. Due to this movement of the sealing strip 18 in the direction of arrow 21, the wedge-shaped gap 20 on the surface 23 of the door frame 4 introduces tarry condensation residues into a groove 22 which is present in the sealing strip 18 .
  • the tarry material 24 which is automatically taken up by the sealing strip 18 in this way forms a reliable seal of the gap between the door plug support 3 and the door frame 4 immediately after the sealing strip 18 has been pressed onto the door frame 4 (i.e. immediately when the coke oven door is tensioned and locked).
  • a rigid link 25 is provided, which is clamped together with the membrane 19 on the door plug support 3.
  • This backdrop 25 covers only a portion of the membrane 19 adjacent to the clamping zone, so that the outer part of the membrane 19 can deform as much as this due to the relative movement between the door body 1 and the door plug support 3 on the one hand and the door frame 4 on the other hand (when tensioning and locking the Coke oven door).
  • Adjustment of the pressure with which the sealing strip 18 rests on the door frame 4 when the coke oven door is closed is possible by means of the adjusting device explained with reference to FIG. 3.
  • the relative position between the door body 1 and the door plug support 3 carrying the sealing element 17 and thus also the effective sealing strip pressure can be adjusted.
  • fixed stops can also be provided.
  • the seal according to the invention explained is particularly suitable for horizontal chamber coke ovens, both for the coke and for the machine side of this oven.
