Definitions

  • the invention relates to a coke oven door for a horizontal chamber coking furnace with a highly heat-resistant door plug projecting into the furnace chamber and connected to the door body, by means of which the furnace filling is kept at a distance from the door body.
  • the stopper has a multiple function together with the coke oven door. It is designed to hold back the furnace filling during coking operation, minimize the heat load on the door body and ensure gas extraction to the gas collection chamber in modern coking ovens.
  • the door body itself forms the abutment for the stopper and also has the task of tightly closing the opening in the door frame.
  • the invention is also based on the object of eliminating the leaks occurring on coke oven doors.
  • the invention is based on the consideration that an uneven heating of the coke oven door takes place during the coking process. This must inevitably result in the coke oven door being warped.
  • the effects of warping increased with increasing furnace height and door length.
  • attempts have been made to counteract this warping by making the door body particularly heavy.
  • each material reinforcement causes increasing deformations.
  • a lifting of the door body is counteracted by the locking pressure of the two locking devices usually provided for each coke oven door. These locking devices grip the coke oven door in the upper and lower third of the door and press the door against the door frame with a force of up to 15 Mp.
  • the thermal effects on the oven door are therefore switched off if possible, insofar as the heating can lead to warping of the oven door.
  • Such coke oven doors are known from DE-C-562494.
  • the known sealing unit is firmly connected to the power transmission unit via bolts. To a large extent, heat reaches the power transmission unit via this connection point. According to the invention, this is prevented in that the sealing unit carries the door plug and in the closed position is held by the force transmission unit alone at the edge.
  • the use of the articulation points is limited to lifting and inserting the door.
  • Preferably two articulation points or brackets are provided. These correlate with the number of usually two locking devices present.
  • the two articulation points are used when converting existing furnaces to doors according to the invention.
  • the locking devices are then retained for cost reasons.
  • the number of two articulation points or brackets is expediently retained.
  • the use of two articulated points spaced apart from one another makes it possible to arrange the articulation points or brackets anywhere between the sealing unit and the power transmission unit.
  • the number of joints or brackets can also be limited to one.
  • the one joint point or holder is preferably arranged in the middle and in the middle in the middle.
  • the sealing unit can be locked with auxiliary devices.
  • the auxiliary devices are located on the door lifting device of the coke oven operating machine.
  • the auxiliary devices can act electromagnetically, mechanically, hydraulically or pneumatically.
  • the furnace door according to the invention enables the use of only one locking device. This has corresponding cost advantages.
  • sealing unit and power transmission unit can also be referred to as a door-in-door construction, with one door of this construction having only the sealing function and the other door of this construction alone having the power transmission functions.
  • this doubling of the door construction does not lead to an expected doubling of the material expenditure, but opens up a way to extremely lightweight construction.
  • the sealing unit as the door intended for the sealing can do without special moments of resistance against bending and corrosion.
  • the sealing unit should be as soft as possible. This has the additional advantage of being particularly easy to adapt to the door frame with which the sealing unit is to seal.
  • the thermal load on the sealing unit is not a hindrance to the soft design of the sealing unit.
  • the temperature requirements for a sealing element made of steel pose no problems. This is all the more true since the sealing element can be provided with insulation on the furnace chamber side. Even the simplest structural steel has proven to be applicable.
  • the sealing element can be designed as a flexible wall a few millimeters thick. Such a flexible wall adapts to every door frame shape. I.e. it can then be brought into contact with the door frame with minimal force.
  • this enables a lightweight construction with a welded steel construction made of standard steel profiles.
  • hollow profiles such frames have optimal rigidity.
  • the frames according to the invention can be excellently ventilated by opening the longitudinal spars at the top and bottom and, if possible, also providing openings at the connection points between the transverse spars and the longitudinal spars.
  • the longitudinal bars act like chimney draft. The resulting air flow creates excellent cooling.
  • the lightweight construction for coke oven doors that opens up according to the invention shows unexpected weight savings. Compared to conventional cast bodies, the weight of doors according to the invention can be reduced by two thirds, in extreme cases by three quarters.
  • the forces required for adapting the sealing element to the deformation of the chamber frame can be both set in a more defined manner using adjustable screws or springs and can also be better corrected in handling.
  • the door structure according to the invention can be made much lighter in weight than conventional doors and is therefore of considerable advantage for construction, maintenance and repair.
  • the door lifting and positioning devices are now loaded with a fraction of the previous forces and are therefore treated more gently. The same applies to the sealing surface of the chamber frame.
  • both units or one or the other unit can be exchanged quickly and easily. While conventional door repairs to membranes that are too common, sealing strips each have to be brought into a repair stand held for this purpose and jacked up there, comparable ones can Damage to the door according to the invention can be remedied by replacing the sealing unit in the door which is still held in the door lifting device. The hoist available on every operating stand is sufficient for this.
  • the sealing element can be provided with an effective surface for sealing which is parallel to the door frame sealing surface, covers the door frame and is variable in distance.
  • the parallelism of the sealing surfaces opens up new sealing options.
  • Soft seals can also be arranged between the effective surface of the sealing element and the door frame sealing surface, which are only introduced into the sealing gap from outside in the form of non-metallic refractory strips during operation with conventional coke oven doors, for the provisional elimination of any leaks that occur.
  • the soft seals are preferably provided with thermal protection towards the furnace chamber. Instead of soft seals, new types of spring seals and labyrinth seals can also be used.

  • the power transmission unit 1 is designed as a hollow profile frame 3, the longitudinal bars of which are denoted by 4 in FIG. 2 and the transverse bars of which are denoted by 5 in FIG.
  • the longitudinal bars 4 are open at the upper and lower ends. Furthermore, there are openings in the longitudinal spars at the connection points to the transverse spars 5, so that heating air in the hollow profile frame 3 can flow freely from the transverse spars 5 into the longitudinal spars 4 and there upwards and exit from the hollow profile frame 3 at the top.
  • the hollow profile frame 3 is made of commercially available square hollow profile made of steel of quality St 37, which has the dimensions 80 mm x 40 mm and a wall thickness of 4 mm.
  • the hollow profile frame can also consist of other profiles such as, for example, hollow round profiles, L profiles, I profiles, T profiles and U profiles. These can be commercially available rolled profiles or welded profiles.
  • the profiles can also be used in various installation positions. This applies in particular to the U-profiles.
  • the door shown in the embodiment according to Figure 1-3 is intended for retrofitting existing 6 m high horizontal chamber coking ovens, the original doors of which are provided with two locking devices 6 which are moved together via a locking rod 7.
  • the locking devices are actuated by a lever mechanism (not shown) on the door lifting device.
  • the locking devices 6 with their locking plates 8 are each screwed to plates 72, which are welded above and below with cross bars 5 of the hollow profile frame 3.
  • compensating plates 73 are provided, which are tools for adjusting the locking unit on the fixed locking hooks, not shown, on the chamber frame.
  • the transverse bar 5 underneath is provided with a recess at 61. Furthermore, 5 stiffening ribs 62 are provided between the locking devices 6 and the transverse bar 5 located below each.
  • An articulated fork 9 is also welded to the upper cross member 5, which is welded to a locking plate 8.
  • the joint fork comprises an eye 10 fastened to the sealing unit 2.
  • the eye 10 and the joint fork 9 together with a joint bolt 11 form an articulated mounting of the sealing unit 2 on the force transmission unit 1.
  • the sealing unit 2 is on two Hinge points held in the power transmission unit 1.
  • the sealing unit 2 consists of a sealing element 12 and an insulation 13.
  • the sealing element 12 is made from a commercially available panel profile shown in Figure 16 6 mm thick to the length of the free legs designated in Figure 16 and Figure 3 with 14.
  • a thickness between 4 and 7 mm is provided.
  • the overall height of the furnace and its width have no influence on the thickness, since the restoring forces of the furnace filling per unit area do not differ significantly from each other with conventional furnace sizes of 4 to 8.5 m.
  • the resulting total pressure is taken into account differently by a corresponding number of screws depending on the furnace height.
  • the sheet profile was sawn in at the points designated 17 in such a way that folding to the profile shape of the edge shown in FIG. 3 and welding to the other edges of the sheet profile is possible.
  • the parallel course of the free leg 14 relates to the sealing surface of the door frame 18, designated by 20.
  • the parallel free leg 14 merges according to Figures 3 and 16 with an inclined web into the rest of the panel profile.
  • the bulge thus given is filled with insulating material.
  • Mineral fibers or ceramic fibers, glass fibers or also lightweight building blocks made of refractory material come into consideration as insulating material.
  • the material is either chosen so that the insulation 13 carries a suitable plug via a door plug holder 21 shown in FIG. 3, or the insulation 13 is penetrated by suitable anchors for the door plug holder 21.
  • Anchors that can be used are, for example, screw anchors that are screwed or welded in the sealing element 12 or that penetrate the sealing element 12 and are secured behind the sealing element with nuts, or bracket.
  • the brackets can consist of cut-to-length L-profiles, which are welded to the oblique profile web of the sealing element 12 at a distance from one another such that one leg runs parallel to the sealing surface 20.
  • the holder can be made in the same way as with direct attachment to the sealing element 12.
  • the door plug holder shown can have any shape.
  • Metallic or non-metallic lightweight plugs are preferably provided for the furnace door according to the invention. In a metallic design, the door plugs then optionally have plates which are hung from the door plug holder 21 overlapping from top to bottom or are secured in another way by bolt connection or plug connection via screw connections on the door plug holder 21.
  • the sealing element 12 is pressed by the hollow profile frame 3 on the free leg 14 via screw bolts 22 against the sealing surface 20 of the door frame 18.
  • a screw nut 23 is welded on the side of the hollow profile frame 3 facing the door frame 18 for each screw 22 and the hollow profile frame 3 is drilled through such that the screw 22 can be screwed into the screw nut 23 from the outside through the interior of the bars.
  • the screws 22 are secured by lock nuts 24 in the respectively required pressing position.
  • the distance between the individual screws is 100 mm in the exemplary embodiment and can be chosen as small as desired.
  • the upper limit of the screw spacing is 250 mm. At such a distance, it is possible to use the screws 22 to effect a completely uniform pressing of the sealing element 12 on the sealing surface 20.
  • Each screw of the exemplary embodiment can be retightened by hand with a wrench, thus eliminating any unevenness in the contact pressure of the power transmission unit 1 in the closed position of the coke oven door.
  • a torque wrench is advantageous as a wrench.
  • a manual setting can also be sufficient.
  • a continuous flat iron can also be welded to the hollow profile frame, which has threaded holes corresponding to the screws 22.
  • each screw 22 is pressed in the exemplary embodiment onto an intermediate layer 25 fastened to the sealing element 12.
  • the intermediate layer is made of metallic or non-metallic material and is easily replaceable.
  • a non-metallic intermediate layer has thermal advantages.
  • the intermediate layer 25 made of non-metallic flexible material, the intermediate layer facilitates a movement of the free leg 14 caused by thermal expansion of the sealing element.
  • the intermediate layer 25 ensures that the sealing element 12 can still be used even after the screw 22 has been incorporated into its contact surface. This is done by replacing the intermediate layer 25.
  • the intermediate layer 25 can be welded as a steel piece to the sealing element 12 or can be inserted as a separate part in a ring holder or other shaped holder welded to the sealing element 12 for this purpose.
  • a soft seal 26 is provided between the free leg 14 and the sealing surface 20 of the door frame 18.
  • the soft seal consists of mineral fibers or heat-resistant plastic and is held on the free leg 14 of the sealing element 12 via an edge protector 27 which is in turn attached to the free leg 14.
  • the edge protector 27 has the shape of an angle and, in the starting position, only partially encompasses the soft seal 26 on the narrow side facing the plug, so that pressing the sealing element 12 leads to the edge protector 27 being a strip running all around on the free leg 14 Deformation of the soft seal 26 is protective against the narrow side facing the plug. In this state, the edge protector 27 prevents sooting of the soft seal by condensing coke oven gases during the coking operation on the leg 14 also rotating in the free leg Soft seal 26.
  • the edge protector 27 prevents excessive pressure and associated damage to the soft seal 26 by contacting the sealing surface 20 of the door frame 18 and the associated securing of the distance between the free leg 14. Normally, the edge protector serves to pre-separate the condensing raw gases.
  • the edge protector 27 is welded, riveted or screwed to the free leg 14 as a circumferential steel strip.
  • the closing contact of the sealing element 12 against the sealing surface 20 with recesses 28 on the rear side of the sealing element 12, which is decisive for the sealing of the coke oven door, is advantageously influenced.
  • the cross-sectional change associated with the recesses 28 results in a high flexibility of the sealing element 12.
  • recesses running transversely to the longitudinal direction of the door can also be arranged between the recesses 28 already present.
  • the cross-sectional shape of the recesses can then be dimensioned much smaller than that of the recesses 28.
  • the recesses are produced by burning out or sawing out or milling the sealing element 12 on the bulged rear side. The opening thus created is closed by sheets which are adapted to the contour of the opening, so that the sealing element 12 regains a closed rear side.
  • the sealing element is pressed by the force transmission unit 1 or the hollow profile frame 3 exclusively against the chamber frame by means of the screws 22.
  • a sufficient joint play of 5-15 mm plus the amount of thermal expansion of the sealing element 2 that results at the hinge point causes the hinge pin 11 to be lifted off the bearing surfaces in the hinge fork 9.
  • This lifting is extremely advantageous by creating a heat-insulating air gap between the bearing surfaces in the joint and further reducing the thermal load on the hollow profile frame.
  • the bearing surface of the hinge pin 12 is also formed by an elongated hole running in the longitudinal direction of the furnace door. This elongated hole arises from the fact that the thermal expansion of the sealing element to be taken into account in the longitudinal direction of the furnace is substantially greater than transverse to the longitudinal direction of the furnace.
  • a releasable coupling is optionally provided instead of the joint shown in FIGS. 1 to 3. Electromechanical and mechanical couplings that are released in the closed position are suitable for this.
  • FIG. 4 shows a further coke oven door according to the invention, which differs from that according to FIGS. 1-2 by a different shape of the sealing element 12.
  • the web designated by 29 in FIG. 4 runs between the free leg 14 and the rear of the sealing element 12, designated 30, exactly perpendicular to the sealing surface 20.
  • This has direct effects on the flexibility and the movement behavior of the sealing element during the closing process.
  • the flexibility and movement behavior of the sealing element are influenced by an S-shaped or similar to a sine line between the free leg 14 and the rear 30 extending web 31.
  • Figure 5a shows a modified channel density 74 with a small profile depth. This profile is created by folding a sheet and allows a variable design of the profile depth or avoids recesses for the locking devices if existing devices have to be used.
  • the sealing element 12 is designed as a flat sheet 32 according to Figure 6.
  • Figure 7 shows another coke oven door according to the invention, which has spring-mounted bolts 33 instead of bolts 22.
  • the associated springs 33 are arranged in the spars 4 and 5 on the bolt 33.
  • the one spring end is supported on a spar surface, while the opposite spring end acts against a disc 35 arranged on the bolt 33, which can optionally be used with a suitable part of the interior of the spring, e.g. 10 mm, filling and the spring centering collar is provided.
  • the disk 35 can rest against a collar (not shown) of the bolt 33 at the end facing away from the spring 34. This results in an installation possibility of attaching the spring 34 and the washer 35 into the spars 4 and 5 of the hollow profile frame and subsequently pushing the bolts 33 through.
  • the bolts can then be secured in a simple manner by pins at the inserted end against falling out.
  • a replaceable sealing strip preferably made of steel, is provided in a further exemplary embodiment.

  • Figure 9 shows another embodiment with a similar, but lower in height sealing strip 38 than the cutting-like sealing strips in conventional coke oven doors.
  • the free leg 14 of the sealing element 12 is folded up at the outer end 39. This gives sufficient design freedom for screwing the sealing strip 38, which can therefore be replaced as well as the sealing strip 36 according to Figure 8.
