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 in such a way that an outwardly opening wedge-shaped gap between the sealing strip and door frame and a movement of this sealing strip result 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.
  • an iron door body which has an upwardly projecting, apparently all-round stiffening frame and a flange-like projection which extends outside this stiffening frame, with on the flat underside of this door body - with the interposition of a heat-insulating one thin asbestos slab - an iron stone holder, i.e. a kind of door plug support, is attached, which has a pot shape that is open at the bottom for receiving and holding a fire-resistant door lining having.
  • a membrane sealing device On the top of the flange-like protrusion of this door body, a membrane sealing device is carried, which contains two elastically-resilient, membrane-like frame or ring-shaped surrounding plates arranged at a distance from one another, on the outer peripheral edge of which a peripheral sealing blade in the form of tapered edges each has a special -T-iron are attached, which press against their facing outer surface of the door frame.
  • This overall approximately frame-shaped or ring-shaped membrane sealing device is held by means of lugs and pressure pieces and pressure screws attached to the stiffening frame of the door body on the flange-like projection to form a surrounding space and pressed against the mentioned outer surface of the door frame.
  • This known coke oven door therefore already does not match the embodiment as it is assumed in the preamble of claim 1.
  • 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, in particular in coke ovens with horizontal oven chambers.
  • the membrane sealing device has two metal membranes, each of which is made of an essentially continuous sheet metal plate and is curved or domed outward in an approximately pot-lid shape, with its central regions one of the opposite sides of the - in the form of a - sheet-shaped - spacer plate support is fastened so that the two mutually spaced metal membranes and the spacer plate between them form a kind of sandwich-like membrane sealing unit, between their opposite outer edge areas a surrounding space is formed.
  • This membrane sealing device is clamped between the door stopper and T-connections, preferably screwed, which connect this door stopper holder to the door body.
  • the general shape of the inner and outer metal membranes can be essentially identical, only the inner metal membrane having correspondingly smaller external dimensions (length, width, height) than the outer membrane. This results in a simple design, manufacture and fastening with a relatively simple and inexpensive construction of the coke oven door, in particular in the area of its sealing device.
  • the two metal membranes arranged one inside the other are through the devices for tensioning and locking elastically deformed, and as a result, the peripheral edges of both metal membranes bear 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 a cup-lid shape, 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, which forms a flat spacer element, in such a way that a peripheral 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 a little more clearly 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 sealing surface have 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 can advantageously be exploited to - depending on the mode of operation - for example a possibly leaking gas, in particular dangerous (toxic) 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, for example, contamination or explosive ignition.
  • the outer metal membrane 10 has an opening 15 with a pipe socket 16, for connection to a corresponding suction device or blowing device (not illustrated in more detail here).
  • the coke oven door in turn essentially comprises a door body 1 'with a door plug 4' protruding into the opening 2 'of a door frame 3' and a door plug holder 11 'carrying the latter with the aid of T-connections 5', and essentially one membrane sealing device 8 'assembled from the inner metal membrane 9' of the outer metal membrane 10 'and the door plug support 11' arranged between them.
  • a rigid link 21 which serves to limit the elastic Deflection of the outer metal membrane 10 ', provided and clamped on the outside of this outer metal membrane 10' 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.
  • this link 21 only covers a part of the outer membrane 10 'adjoining the clamping zone, so that the outer edge region 10'b of this outer membrane 10' can deform as much as this is caused 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).
  • the elastic deflection of the inner membrane 9 ' can also be limited by a rigid link 22, which is only indicated by dash-dotted lines and which can also be clamped between the inner membrane 9' and the door plug support 11 'with the through screws 13'.
  • FIG. 3 A look at FIG. 3 further shows that the setting device between the door body 1 'and the T-connections 5' can also be modified in comparison to the example according to FIG.
  • the door body 1 ' is provided with an adjustment block 25 (a corresponding number of such adjustment blocks 25 can be provided on the entire 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 'with that of the door body 1' can be achieved.
  • a leveling opening can also be provided at at least one point along 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).
