Definitions

  • the invention relates to a coking furnace door with a sealing lamella formed as a circumferential profile, which contains a sealing strip which comes with a cutting edge to bear against the furnace frame and a sealing plate which is connected with one leg approximately at right angles to the sealing strip and is fastened to the furnace door with another leg and also with the sealing strip pressing angular pressure tabs and with compression springs arranged between the pressure tabs and abutments attached to the furnace door.
  • Coking oven doors are known in which the seal is provided by a sealing lamella provided with a cutting edge, which is pressed onto the oven frame by adjustable but essentially rigid tensioning elements (DE-B-1 149330, DE-B-1 267664, DE-U 1 967 236).
  • the basic disadvantage of these designs is the lack of an automatic adaptation of the sealing lamella to temperature-related deformations of the oven door and oven frame.
  • Coking oven doors are also known in which the sealing lamella is pressed against the sealing surface of the oven frame at several points on the periphery of the oven door (DE-B-1034137, DE-A-27-55 020, FR-A-22 19 214, GB-A-737 580).
  • the sealing lamella and the pressure plates under the action of the compression springs are fastened to the furnace door by means of separate screws.
  • the angled pressure plates are screwed onto the end of one leg and thus perform a swiveling movement around this screw attachment point under the action of the compression springs when they track the sealing lamella in the event of thermal expansion of the oven door or oven frame.
  • the pressure forces no longer act exactly in the direction of the sealing strip, which can result in a poor seal.
  • Another disadvantage is the considerable assembly effort required due to the separate screw fastening of the sealing lamella and pressure plates.
  • pressure bolts are provided for pressure transmission from the compression springs to the sealing strip provided with a cutting edge, which are slidable in guide cylinders attached to the periphery of the furnace door.
  • the sealing lamella is attached to the oven door using separate screws.
  • a disadvantage of this design is the very cumbersome assembly of the sealing lamella and the tensioning devices used to generate the resilient sealing pressure.
  • the sealing plate is fastened to the furnace frame by means of clamping plates and clamping screws, the clamping plates being connected to an upper and a lower guide plate, in which a pressure spring is placed on the sealing plate pushing bolt is slidably guided.
  • a pressure spring is placed on the sealing plate pushing bolt is slidably guided.
  • another clamping screw is used, which is held in an extension of the furnace frame and is in engagement with the one guide plate.
  • the invention is therefore based on the object, while avoiding these shortcomings of the known designs, to provide a coking oven door of the type mentioned, the sealing device of which can be attached to the oven door in a particularly simple manner and also ensures a perfect seal between the oven door and the oven frame in the event of thermal expansion.
  • hook screws of T-shaped profile are provided which have a first bolt serving to hold the abutment and for slidably guiding the pressure plate, and also arranged at right angles to the first bolt, for fastening the hook screw to the furnace door second bolt and an extension provided for the first bolt, which is used to fasten the sealing lamella to the furnace door.
  • the same screws are used to fix the sealing lamella and the pressure plates on the furnace door, furthermore for the sliding guidance of the pressure plates and for holding the abutment for the compression springs.
  • the structural design is considerably simplified and assembly is made considerably easier, especially since only holes for receiving the second bolt of the hook screws have to be drilled in the oven door.
  • the very compact hook screws can be manufactured in the workshop.
  • the pressure tabs are slidably guided on the first leg of the hook screws, they always act - regardless of the size of temperature-related deflections - exactly in the direction of the sealing strip, against which they rest under the action of the compression springs. This ensures that the oven door and oven frame always have a perfect seal, even with larger thermal expansions.
  • the door body of U-shaped cross section consists of a front plate 4 and lateral and upper and lower walls 5.
  • the walls 5 there are bores in which - distributed over the circumference of the oven door - hook screws 6 are seated. These hook screws 6 serve to fasten the sealing lamella 2 to the oven door and also serve to hold and guide those parts which hold the sealing strip 3 in sealing contact with the oven frame 1.
  • the hook screw 6 has an essentially T-shaped profile and consists of a first bolt 7, a second bolt 8 arranged at right angles to the bolt 7 and a clamping projection 9 provided as an extension of the bolt 7.
  • the first bolt 7 is provided with thread 10 at its free end and carries an adjusting nut 11.
  • An angle bracket 12, which forms the abutment for a compression spring 13, is adjustably arranged on this bolt 7.
  • a pressure tab 14 is slidably guided, on which the compression spring 13 is supported.
  • the pressure plate 14 has a socket-shaped extension 15 with which it is guided on the bolt 7.
  • the free end of the clamping projection 9 arranged in the extension of the bolt 7 rests on a flat strip 18 which in turn rests on the sealing lamella 2 and presses it against the wall 5 of the furnace door.
  • the sealing lamella 2 contains a sealing strip 3, which comes into contact with the furnace frame 1 with a cutting edge.
  • a leg 19 which merges into another leg 20, again bent by approximately 90 °, which in the manner already explained by the clamping projection 9 of the hook screw 6 between the flat bar 18 and the wall 5 of FIG Oven door is clamped.
  • the pressure plate 14 engages with its end 21 facing the sealing strip 3, which is U-shaped in cross section, over the sealing strip 3 and thus transmits the pressure exerted by the compression spring 13 on the pressure plate 14 to the sealing strip 3 (approximately perpendicular to the sealing surface between the sealing strip) 3 and furnace frame 1).
  • the pressure plate is provided with two lateral guide pins 22 which engage around the angle plate 12 laterally.
  • the components which correspond to those of the exemplary embodiment in FIGS. 2 and 3 are designated by the same reference numerals and are not explained separately.
  • the abutment for the compression spring 13 is formed by an adjusting nut 28 arranged within the angle bracket 12 on the bolt 7 of the hook screw 6 in the variant according to FIG. 4.
  • the adjustment of the sealing plate 2 and the setting of the bias of the compression spring 13 can be carried out independently of one another.
  • the leg 20 of the sealing lamella 2 can be more or less approached to the furnace frame 1 via the angle bracket 12.
  • the spring pressure exerted on the sealing strip 3 via the pressure plate 14 can be set to the desired value.
  • This embodiment also makes it possible to subsequently change the spring preload (by means of the adjusting nut 28) without having to loosen the leg 20 of the sealing lamella 2 on the wall 5 of the furnace door (by means of the nut 17).
  • the abutment for the compression spring 13 is formed here by an adjusting nut 29 which sits on an externally threaded threaded sleeve 30, which in turn is slidably arranged on the bolt 7 of the hook screw 6 and is supported on the angle bracket 12.
  • the angle bracket 12 and the pressure bracket 14 are spread apart by the compression spring 13.
  • the abutment for the compression spring 13 is formed here by a threaded sleeve 31 which is provided with an external thread and which extends freely through a through hole in the angle bracket 12 and carries an adjusting nut 32 which serves to adjust the angle bracket.
  • an adjusting nut 33 is arranged, which serves for the longitudinal displacement of the threaded sleeve 31 relative to the bolt 7 and with which the prestress of the compression spring 13 can thus be adjusted.
  • the sealing lamella 2 At the transition from the sealing strip 3 to the leg 19 of the sealing lamella 2 there is a longitudinal groove 34, through which a cross-sectional tapering of the leg 19 results in the transition area. As a result, the sealing lamella 2 is easily deformable at this point. As a result, the leg 19 of the sealing lamella 2 can change its angular position in relation to the sealing strip 3 in the event of thermal expansion of the furnace door and furnace frame. This prevents the sealing strip 3 from tilting and ensures a consistently good sealing effect between the sealing strip 3 and the furnace frame 1.
