Definitions

  • the invention relates to a coke oven with coke oven doors that can be pressed against the chamber frame and thus seal them, which has a coking plate on the inside of the door body by means of spacers arranged at a distance, a sealing edge assigned to the door body with a reset safety device and the door body and thus the pressure element influencing the sealing edge.
  • the main task of the coke oven doors in general is to close the side openings required for emptying the coke oven in a gas-tight manner during the coking process in order to secure the coking process and prevent emissions to the atmosphere.
  • the coke oven doors have all-round sealing edges, which, for example, are also placed on sealing plates designed as membranes. The sealing plates and thus the sealing edges are pressed onto the chamber frame with a contact pressure of approximately 10 kg / cm sealing edge length. Depending on the size or height of the coke oven, a contact pressure of 15 t and more is necessary to ensure sufficient tightness of the coke oven. This high contact pressure is transmitted from the door body to the chamber frame via the latch hook or latches.
  • spring pots or similar units are pretensioned when the door is put on, which must then apply the necessary contact pressure. Up to now, two such spring pots per door have been used in ovens of 5 to 7 m in height.
  • US-A-2 878 170 shows a construction in which in turn a stable door stopper is provided with a stable door body, whereby a type of membrane seal, which has already been described above, is provided, the sealing plate of which can be influenced via a hollow body equipped with variable volumes so that the Sealing edge rests on the chamber frame.
  • the invention has for its object to provide a coke oven, the coke oven door overall, i.e. including the front door plug can be adapted to the bending line of the chamber frame so that an effective seal of the coke oven from the atmosphere is ensured.
  • the door body carrying the coking plate is formed only by a continuously elastic sealing plate, which holds the holding devices for the door lifting claws and the locking bolts and the all-round, actively designed chamber frame, sealing plate and sealing blade which only influences the edge area close contact pressure element are assigned.
  • Such a coke oven door is so elastic that bending forces due to thermal influences can no longer occur or only to a very small extent.
  • a coke oven door is particularly suitable for applying the necessary pressing forces, in which the pressing element is designed, as is known per se, as a hollow body with a variable volume enclosed by a U-profile cage, the U-profile cage being provided via the locking bolts is supported on the latch hook.
  • a further embodiment provides that the sealing plate is edged all round to form a U-profile cage, in that the hollow body, acting as a cutting edge, rests directly on the chamber frame and is arranged to act on it and on the U-profile cage.
  • a coke oven door advantageously represents a structural unit that only has to be supplemented by elements for attaching the door lifting claws and locking bolts. It is therefore characterized by low manufacturing costs, favorable installation and maintenance conditions and above all by Ver Appropriate material for the hollow body by completely closing the coke oven against the atmosphere due to the relatively large sealing surface.
  • the size or better the effective area of the support of the hollow body on the chamber frame can be influenced by the shape of the hollow body or by its quality. With suitable units, the sealing surface can be varied even during operation, ie during the cooking process.
  • a distributor strip made of heat-insulating material between the hollow body made of heat-resistant material and the sealing plate.
  • the hollow profile lies on this distributor strip, for example, a hose, so that it is protected from the more or less hot sealing plate and its shape and contact surface can be influenced by the shape of the distributor strip.
  • the U-profile cage is intended both to protect the hollow body and as an abutment, for which purpose it is arranged with the free web or flank ends resting on the sealing plate. It is provided according to the invention that the U-profile cage is divided several times in the longitudinal direction into partial lengths which are connected to one another via joints and, moreover, has flanks weakened by transverse slots. In this way, the U-profile cage can easily adapt to the bending shape of the chamber frame and at the same time it is given additional mobility in the direction of the furnace axis. In addition, the use of partial lengths makes assembly and disassembly easier.
  • a simple construction and at the same time reliable transfer of the contact pressures is achieved in that the locking bolts are fastened correspondingly to the U-profile cage with the locking hooks arranged on the chamber frame, or extend across the door body and either on the U-profile cage or on one the entire length of the door body arranged center strut or the locking device are arranged to support.
  • Various variants are proposed here, the last of which is particularly suitable for existing coke oven doors in which, for some reason, the existing locking devices cannot or should not be dispensed with.
  • the continuous design of the locking bolts leads to a further simplification of the construction, but can possibly lead to difficulties when hooking in the coke oven doors if the chamber frames are bent differently on both sides.
  • a significant reduction in cleaning work is achieved according to the invention in that the sealing blade is arranged on the chamber frame, the inner edge of which is chamfered, or is part of the chamber frame.
  • the inside of the sealing plate is retained as a surface, so that any contamination that may still occur can be easily removed, while they are generally harmless in the area of the chamber frame and the sealing cutting edge and can also be easily removed .
  • a chamfer on the inner edge of the chamber frame is intended to ensure that the coking gases are brought up to the sealing cutting edge with full heat, so that contamination and contamination, particularly due to graphite formation, cannot occur at all.
  • the sealing plate at the edge and to arrange the hollow profile there.
  • the locking bolts can be molded onto the arch or its outer wall or connected to it at the deepest point of the arch. To ensure that the hollow body in each case assumes the intended position when the coke oven door is inserted, it is provided that the hollow body is connected point-wise to the web of the U-profile cage.
  • the invention is characterized in particular by the fact that a uniform and targeted application and introduction of the contact pressure is ensured.
  • the coke oven door according to the invention is characterized by a very low weight, a high degree of elasticity or flexibility, both over the longitudinal as well as over the transverse axis. Due to the low weight, there is an advantageously simple handling. With the considerable weight reduction, which i.a. is also achieved through the use of the coking plate and the convenient handling of the coke oven doors also simplifies the door lifting and operating machines.
  • the targeted formation of the sealing edge and the corresponding area of the door body and the chamber frame leads to significantly reduced cleaning work, which at the same time leads to a protection of the coke oven door itself.
  • Fig. 1 shows a perspective view of an elastic coke oven door 1 in a lightweight construction.
  • the door body 2 of the coke oven door 1 is formed here only by the sealing plate 3 designed as a membrane, the angular profile 4 running parallel to the edge and the sealing cutting edge 5.
  • the Sealing cutting edge 5 is actually not part of the coke oven door 1, but rather the chamber frame 7.
  • the angle profile 4 serves as a holding device 6 both for the holding claws (not shown) and for the pressure elements and their accessories.
  • several locking hooks 8 are provided as connecting elements between the door body 2 and the chamber frame 7, which correspond to the locking bolts 9.
  • a circumferential light frame designed as a U-profile cage 10 is hooked into the corresponding locking hooks 8 of the chamber frame 7 via the locking bolts 9. Since all other parts of the door body 2 are connected to this U-profile cage 10, a fastening or connection of the door body 2 to the chamber frame 7 is thus achieved at the same time.
  • the U-profile cage 10 can consist of short, approximately 0.5 to 1 m long individual pieces which are connected to one another by joints. This gives the U-profile cage 10 a sufficiently large elasticity in the longitudinal direction and thus allows the sealing plate 3 or the entire coke oven door to adapt to the bends of the chamber frame 7.
  • the pressure element 11 within the U-profile cage 10 is the pressure element 11, in the example shown a hydraulically or pneumatically actuated hollow body 12.
  • the hydraulic or pneumatic actuation of the hollow body 12 causes the membrane or the sealing plate 3 against the sealing cutting edge 5 and the chamber frame 7 pressed.
  • the sealing plate 3, the cutting edge 5 and the chamber frame 7 thus form a gas-tight seal of the coke oven against the atmosphere.
  • the special arrangement and design of the pressure element 11 leads to a uniform distribution of the required contact pressure over the entire length of the sealing cutting edge 5. The forces required for this are no longer transmitted via the door body 2, but rather directly via the locking bolts 9 and locking hooks 8 into the chamber frame 7 headed.
  • the U-profile cage 10 encloses the hollow body 12 or the pressure element 11. Its flanks 14, 15 are provided with weakening slots transversely to their longitudinal direction in order to further increase their flexibility.
  • the hollow body 12 rests in it on the distributor bar 17, which preferably consists of heat-insulating material in order to additionally protect the hollow body 12 from the heat emanating from the coke oven.
  • the distributor bar 17 also serves to even out the contact pressure.
  • the hollow body 12 lying in the U-profile cage 10 is brought and held in a predetermined position by the spring pressure cylinder 18, the web ends 16 of the U-profile cage 10 resting on the sealing plate 3 at least at the beginning of the pressing process.
  • the individual spring pressure cylinders each have an upper and a lower flange 19, 20, in which bores 21, 22 are arranged for the passage of the connecting screws.
  • the spring 24 is arranged, which brings the desired resilient connection between the rest of the door body and the sealing system.
  • a setting angle 25 is provided as a connection between the spring pressure cylinder 18 and the angle profile 4, which is arranged so as to be displaceable via the elongated holes 28. The setting is effected via the pressure screw 27 guided in the cross piece 26.
  • the flanks 14, 15 of the U-profile cage 10 are slotted as mentioned, i. H. they have transverse slots 30 arranged at intervals.
  • the guide bolts 31 in the region of the flanks 14, 15 can be inserted in recesses formed in the sealing plate 3 and thus facilitate assembly by precisely specifying the predetermined position of the U-profile cage 10.
  • the sealing cutting edge 5 is arranged close to the inner edge 35 of the chamber frame 7 and is thus exposed to the hot gases.
  • the opening 36 in the locking hook 8 is adapted to the locking bolt 9 to such an extent that it has sufficient but not too great play.
  • the hot gases are guided in the rest of the cavity or gas outlet channel, which is formed between the door body or the sealing plate 3 and the coking plate 39 held at a distance from the door body by spacers 38.
  • Fig. 2 illustrates that the gases each reach the area of the sealing cutting edge 5 without difficulty and without cooling beforehand. Therefore, there will be hardly any caking or dirt in this area.
  • the inner edge 35 is chamfered for this.
  • FIG. 3 shows a longitudinal section through one of the two furnace heads with an inserted coke oven door, the sealing plate designed as a membrane seal being loaded precisely in the area of the sealing cutting edge 112 via the all-round hollow bodies.
  • the coke oven door is labeled 101, while the oven frame, in front of which the door body 103 is held via the locking device 104, 105, is labeled 102.
  • This is still a very complex construction.
  • the illustration shown in FIG. 4 is a lighter construction.
  • the coke oven door 101 On the inside, the coke oven door 101 according to FIG. 3 carries the membrane or the sealing plate 110 with the sealing cutting edge 111, 112 formed in the edge area.
  • the insulating layer 119 which is held on the door body 103 or the sealing plate 110 via the spacers 123, 124.
  • the spacers 123, 124 carry the coking plate 120 at the end, which consists of individual shields 125, 126, each of which is screwed or hidden to the shield holders.
  • the base of the spacers 123, 124 is screwed to the actual door body 103, for example, and holds the insulating layer 119 on the sealing plate 110 via the cover plate 121.
  • the gas discharge duct 117 is formed, through which the released gases are discharged in the direction of the receiver.
  • FIG. 4 shows an embodiment in which the sealing plate 3 is only designed to reach the chamber frame 7. This is followed by the U-profile cage 10, in which the hollow body 12 is arranged. U-profile cage 10 and sealing plate 3 are welded, screwed or otherwise connected to one another, so that they form a structural unit and can be connected to the chamber frame 7 by means of the locking bolts 9 in the locking hooks 8.
  • the hollow body 12 rests on the chamber frame 7. Since it is approximately uniformly warm or hot, the hollow body is only exposed to limited temperatures, especially since the hollow body cannot be directly influenced by the hot gas. 4 shows that the hollow body 12 lies flat on the chamber frame 7, that is to say an advantageously wide sealing surface is created.
  • the sealing plate 3 and the cage receiving the pressure element 11 being produced from a plate by folding.
  • the locking bolts 9 are molded onto the cages or, as indicated, are continuous and connected to them.
  • the hollow body 12 or the pressure element 11 is preferably connected point by point to the cage in order to ensure correct positioning.
