Definitions

  • the invention relates to a coke oven door according to the preamble of claim 1.
  • the membrane sealing device has a metal membrane clamped on the door plug support, the peripheral edge of which comes into contact with the door frame is designed as a sealing strip with a sealing strip provided for receiving tar-like condensate.
  • this metal membrane deforms such that there is an outwardly opening wedge-shaped gap between the sealing strip and door frame and a movement of this sealing strip outwards, which results in tarry condensate residues present on the door frame in this wedge-shaped gap and thus in the Slide the existing groove into the sealing strip.
  • the desired sealing of the gap between the door plug support and the door frame is created immediately after the sealing strip is pressed onto the door frame.
  • This invention has for its object to provide a coke oven door of the type required in the preamble of claim 1, which is characterized in the area of its sealing device by a relatively simple membrane design and thereby by an extremely reliable gas seal, especially in coke ovens with horizontal oven chambers.
  • the membrane sealing device in the coke oven door according to the invention has two metal membranes, each curved approximately in the shape of a pot lid, which are arranged at a distance from one another and with their central regions on one of the opposing ones Sides of the door plug carrier designed in the manner of a flat spacer element are fastened.
  • This attachment to the spacer element is provided in such a way that a circumferential space is formed between the opposite outer edge regions of the inner and the outer metal membrane (and the outer peripheral edge of the spacer element).
  • the general shape of the inner and outer metal membranes can be of essentially the same design, only the inner metal membrane having correspondingly smaller outer dimensions (length, width, height) than the outer membrane.
  • the two metal membranes arranged one inside the other are elastically deformed by the devices for tensioning and locking, and as a result the peripheral edges of both metal membranes lie against the door frame or the door frame surface facing them under sufficient pressure .
  • This configuration of the membrane sealing device thus creates a double seal through the two metal membranes, resulting in a results in a particularly reliable seal against the gas in the associated coke oven; and this double gas seal is particularly advantageous in coke ovens with horizontal oven chambers.
  • FIG. 1 in which only the parts of the coke oven door that are deemed necessary to explain the invention are illustrated, while the remaining parts of this coke oven door can be carried out in a manner known per se.
  • the coke oven door contains a door body 1, a door stopper 4 projecting into the opening 2 of a door frame 3 and a door stopper support 11 carrying this door stopper 4 and connected to the door body 1 by T-shaped connections 5.
  • the door plug 4 and the door plug support 11, both of which are carried by the door body 1, are located at the lower end of this door body.
  • the T-connections 5 are connected to the door body 1 by an adjusting device which, in the transverse direction (FIG. 1), has one or - as shown - two adjusting spindles 6 and in the longitudinal direction of the door body 1 (ie vertically 1) can have a correspondingly greater number of such adjusting spindles 6 in succession to the plane of the drawing in FIG.
  • the adjusting spindles 6 engage with threaded blocks 7 fastened to the door body 1, through whose threaded bore 7a the adjusting spindles 6 extend so far that their lower ends 6a (below the underside of the door body 1) coexist the T-connections 5 located there can be connected in such a way that with a corresponding rotary movement and the associated longitudinal displacement thereof Adjusting spindles 6 a height adjustment of the T-connections 5 with the door plug support relative to the door body 1 can be brought about.
  • a membrane sealing device 8 is also fastened to the door plug support 11, the peripheral edges of which, as will be explained in detail later, bear against the door frame 3 under pressure in the closed state of the coke oven door.
  • This membrane sealing device 8 has two metal membranes, each curved approximately in the shape of a pot lid, namely an inner metal membrane 9 and an outer metal membrane 10. These two metal membranes 9, 10 are arranged at a mutual distance from one another, the two membranes 9, 10 can be of approximately the same shape in their general form and the outer metal membrane (length, width, height) is kept somewhat smaller than that outer metal membrane 10, as can be seen from the representations in FIGS. 1 and 2. As shown in FIG. 1, both metal membranes 9, 10 are fastened with their central regions 9a, 10a on each side of the door plug support 11 forming a flat spacer element in such a way that a circumferential one between their outer edge regions 9b, 10b and the outer peripheral edge 11a of the door plug support Room 13 is formed.
  • this door plug support could be produced by suitably designed and arranged strips or also by a correspondingly designed frame. However, it is preferred to use this door plug support in the form of a flat spacer plate 11 execute, the metal membranes 9, 10 determined between their central regions 9a and 10a.
  • a kind of sandwich-like membrane sealing unit is formed by the two metal membranes 9, 10 arranged at a distance from one another and the spacer plate plate (door plug support) 11 located between them.
  • the spacer plate 11 is fixed in the vicinity of its outer peripheral edge 11a to the two metal membranes 9, 10 by means of through-bolts (including nuts) 13, but is detachably screwed to said membrane sealing unit.
  • the membrane sealing unit thus essentially formed from the two metal membranes 9, 10 and the door plug support is in turn clamped between the door plug 4 and the T-connections 5.
  • the membrane sealing unit and the door plug 4 are detachably connected to the T-connections 5 by the screws 14, while separate connecting screws, not shown in the drawing, ensure a releasable connection only between the membrane sealing unit and the door plug 4 . All of these parts are thus adjustable by the adjusting spindles 6 relative to the door body 1 on the one hand and thus also to the door frame 3.
  • Fig.2 shows in a slightly enlarged scale detail section of Fig.1 etaws the formation and arrangement of the two metal membranes 9, 10.
  • the free peripheral edges 9c and 10c pointing towards the door frame 3 of both Metal membranes 9, 10 a flat seal have an area with a width corresponding essentially to the material thickness of the associated membrane.
  • the peripheral edge 9c of the inner metal membrane 9 forms a plane 9d
  • the peripheral edge 10c of the outer metal membrane 10 defines a plane 10d.
  • the peripheral edge 9c of the inner metal membrane 9 now projects further against the upper side 3a of the door frame 3 to be sealed than the peripheral edge 10c of the outer metal membrane 10, that is to say in other words, that through the peripheral edge 9c of the inner metal membrane
  • the plane 9d formed 9 has a smaller distance a from the upper side 3a of the door frame 3 to be sealed than the plane 10d (distance A), which is formed by the peripheral edge 10c of the outer metal membrane 10.
  • the previously described sealing engagement of the peripheral edges 9c, 10c of the two metal membranes 9, 10 results in an extremely reliable sealing of this coke oven door from the door frame 3.
  • the space 12 formed between the outer edge regions 9b and 10b of the two metal membranes 9, 10 can then still be in are advantageously used to - depending on the mode of operation - for example a possibly leaking gas, in particular dangerous (poison ges) Aspirate and neutralize gas or inject a corresponding gas or water vapor or the like into this annular space 12 in order to neutralize any gas that may accumulate on the spot, thereby preventing contamination or explosive ignition, for example.
  • the outer metal membrane 10 has an opening 15 with a pipe socket 16, for connection to a corresponding suction device or blowing device, which is not illustrated in detail here.
  • the coke oven door thus again essentially comprises a door body 1 'with an in the opening 2' of a door frame 3 'projecting door stopper 4' and one of the latter with the aid of T-connections 5 'carrying door stopper holder 11' and one essentially from the inner metal membrane 9 'the outer metal membrane 10' and the interposed door plug support 11 'assembled membrane sealing device 8'.
  • a rigid backdrop 21 which serves to limit the ela tical deflection of the outer metal membrane 10 ', provided and by means of the through screws 13', which firmly connect the inner membrane 9 ', the outer membrane 10' and the door plug support to one another, is clamped on the outside of this outer metal membrane 10 '.
  • this link 21 only covers a portion of the outer membrane 10 'adjacent to the clamping zone, so that the outer edge region 10'b of this outer membrane 10' can deform as much as this by the relative movement between the door body 1 'and T-connections 5 'on the one hand and door frame 3' on the other hand (when tightening and locking the coke oven door) is due.
  • the elastic deflection of the inner membrane 9 ' can be limited by a dashed line indicated rigid link 22, which' between the inner membrane 9 'and the door plug support 11' can also be clamped with the through screws 13 '.
  • a particularly simple but also quite effective way to limit the elastic deflection of the inner membrane 9 ' can also be achieved in that such a limiting device is formed by a correspondingly rounded lower edge formation 11'b of the door plug support 11'.
  • a rounded lower edge formation 11b is also indicated in the first exemplary embodiment in FIGS. 1 and 2.
  • a look at Figure 3 also shows that the adjusting device between the door body 1 'and the T-connections 5' can be modified compared to the example shown in Figure 1.
  • the door body 12 ' is provided in this case with an adjusting block 25 (a corresponding number of such adjusting blocks 25 can be provided on the whole coke oven door).
  • an adjusting spindle 26 can be adjusted in the longitudinal direction by means of a first threaded section 26a.
  • the adjusting spindle 26 If the adjusting spindle 26 is now rotated, it carries out a longitudinal displacement in the adjusting block 25. Due to the different thread pitch of the two threaded sections 26a and 26b, the holding piece 27 then moves a somewhat smaller distance, so that a very sensitive height adjustment of the T-connection 5 'can be achieved with that with respect to the door body 1'.
  • a leveling opening can also be provided at at least one point over the length of the coke oven door, which then has both metal membranes and the door plug support 11 and 11 'located between them in a corresponding manner.
  • Such a leveling opening can, for example, be designed essentially in the same way as is explained in EP-B-1 44 649 (with reference to FIG. 1).
