Definitions

  • the invention relates to seals for coke oven doors according to the preamble of claim 1, and their use.
  • Coke oven doors are subject to special requirements with regard to tightness, whereby a reliable seal is required even after a long period of operation.
  • a major reason for this lies in the severe contamination of the doors, but especially in the contamination of the sealing elements by tarry components, which are reflected in the coke oven gas on the sealing elements and on the sealing surface on the door frame.
  • These greasy residues make periodic cleaning measures necessary, which are usually associated with a considerable amount of work and affect the sealing elements in such a way that an adequate seal is no longer guaranteed in the known door constructions after a long period of operation.
  • This is aggravated by the fact that the sealing elements must be adjusted to the bending line of the coke oven door that only arises during operation. Since this bending line changes particularly when the coke oven door is open for a long time or after a long period of operation, such sealing elements must be adjustable.
  • the spring forces must be set so that the frictional forces of the hook bolts are overcome and the section modulus of the hammer impact bars in the desired direction of deflection is overcome. This means that in total a large force is required, which in turn requires high door locking forces. Due to the high door locking forces, large loads are placed on the door locking elements and the door frame. If this door seal was retrofitted (retrofitted), the door locking device would have to be redesigned due to the high forces required.
  • the hammer strips and other sealing elements are usually welded at the corners. Welded connections are also made when the sealing elements are repaired. With these welded joints, changes in structure and dimensions occur due to the temperatures required for welding, which necessitate time-consuming reworking of the sealing elements.
  • the invention has for its object to provide seals for coke oven doors that adapt to all unevenness of the door frame with low locking forces, so that the known door locking devices can also be used when retrofitting. In addition, welded joints should not be used for the seals.
  • the section modulus in the direction of the desired deflection can be greatly reduced. This reduction depends on the slot depth and slot width as well as the number of slots. Due to the appropriate design of the slot depth, slot width and number of slots and the material thickness, the sealing edge of the comb-shaped sealing strip is easily deformable and can therefore adapt very well to any unevenness in the sealing surface of the door frame. Due to this adaptability of the comb-shaped sealing strip, the sealing effect is significantly improved.
  • the slots can be made in all known geometric shapes. It is also possible to make the slots closed at their end opposite the sealing edge with a web. In this embodiment too, the section modulus is reduced in the direction of the desired deflection.
  • the slot width can also be reduced at the end opposite the sealing edge, so that when the comb-shaped sealing strip bends, the resistance moment is changed due to the smaller slot width as soon as the opposite sides of the slot touch.
  • the comb-shaped sealing strip can be attached point-wise with screws, pressure washers or springs or with a pressure strip.
  • the pressure bar distributes the punctiform contact forces evenly over the length of the pressure bar.
  • the comb-shaped sealing strip according to the invention can be used both for new coke oven doors and for existing coke oven doors.
  • a coke oven door with a hammer molding only the existing hammer molding needs to be replaced with the comb-shaped sealing strip.
  • the existing hammer blow bar does not necessarily have to be replaced.
  • mount the comb-shaped sealing strip in addition to the hammer impact strip.
  • the comb-shaped sealing strip can either be provided with its own fastening or the existing fastening of the hammer impact strip can be used.
  • the comb-shaped sealing strip according to the invention is well suited for repairs of sealing elements.
  • a repair e.g. If the sealing edge of an existing sealing strip or the sealing surface of the door frame is damaged or worn, the full sealing function can be restored by installing the comb-shaped sealing strip at the damaged point.
  • the comb-shaped sealing strip is precisely adapted to the wear point. It is also possible to mount the comb-shaped sealing strip overlapping on the existing sealing element in the area of the damaged area.
  • the seal between the comb-shaped sealing strip intended for the repair to the existing sealing strip takes place by positive locking and not, as previously, by welding.
  • This seal has the advantage that the time-consuming reworking of the sealing edge, as is necessary for welded connections, can be omitted.
  • This form-fitting sealing can also be used with all sealing elements for coke oven doors known from the prior art. It is possible to make a positive connection by means of a miter or butt joint or a step-shaped joint as well as a diagonal joint. By using a Sealant prevents the coke oven gas from blowing off from the start. The tar also seals later.
  • This form-fitting sealing can also be provided in the area of the corner connections.
  • the butt joint can also be provided with a flexible seal. A particularly good seal that is effective even after a long period of operation is obtained if the flexible seal is installed in the miter cut of a corner connection.
  • This seal can also be coated with an elastic sealant.
  • the flexible seal can consist of sealing plates which are formed as round heads at their ends which protrude from the butt joint. This creates a spring action, which means that the sealing plates can seal against any gaps that may arise due to the spring action.
  • These sealing plates can be coated with a material such as e.g. Teflon, glass wool or the like.
  • the sealing plates can also be coated on the outside with an elastic sealant.
  • a double T seal can advantageously be provided for sealing the gas channels known from WO 01/30939 A2.
  • the double-T seal for gas ducts can be produced particularly advantageously from the flexible seal with sealing plates and round heads.
  • the sealing plates are simply flanged in the sense of the double-T seal until they rest on the walls of the gas duct.
  • Plug connections are particularly suitable if they are used as a connection in the gas channels known from WO 01/30939 A2.
  • FIG. 1 shows a schematic illustration of the comb-shaped sealing strip
  • FIG. 2 shows the comb-shaped sealing strip with screws and pressure washers
  • Figure 3 is a comb-shaped sealing strip with screws and a pressure strip
  • FIG. 4 shows a representation of the comb-shaped sealing strip, which has adapted to unevenness in the door frame
  • FIG. 5 shows a schematic illustration of a flexible sealing element with spring action
  • FIG. 7 the sealing of sealing strips with a T-piece and a double-T
  • Slits 3 reduce the section modulus of the comb-shaped sealing strip 1 in the direction of the desired deflection.
  • the section modulus can be specifically influenced by designing the slot width 4 and the slot depth 5.
  • the comb-shaped sealing strip 1 is fastened in a punctiform manner to the door body (not shown) using screws 6 and pressure plates 7.
  • the comb-shaped sealing strip 1 is fastened to the door body (not shown) with screws 8 and a pressure strip 9.
  • the punctiform contact forces of the screws 8 are evenly distributed over the strip length of the contact strip 9 by the contact strip 9.
  • FIG. 4 shows the k-shaped sealing strip 1 with the pressure strip 9, which has optimally adapted to the unevenness 12 and 13 of a door frame 11.
  • Figure 5 shows a flexible sealing element which consists of two sealing plates 15 and 16 which are connected at their ends by round heads 17 and 18.
  • the flexible sealing element is attached in the joint between two sealing strips such that the round heads 17 and 18 are arranged outside the sealing strips.
  • a spring tension is generated in the joint by the round heads 17 and 18.
  • the sealing plates 15 and 16 press resiliently against the sealing strips connected by butt joint.
  • the space between the sealing plates 15 and 16 and the round heads 17 and 18 can be provided with a filling 19.
  • This filling 19 can either consist of stuffing material or also of elastic material which increases the spring action.
  • the outside of the sealing plates 15 and 16 can additionally be provided with a sealing agent, which can also be elastic.
  • FIGS. 6a, b, c, and d show different forms of impact sealing by positive locking with and without flexible sealing elements.
  • the sealing strips 20 and 21 can be sealed by a miter joint 22, a butt joint 23, a step joint 24 and a diagonal joint 25.
  • flexible sealing elements 26, 27, 28 and 29 can be arranged in the joints.
  • FIG. 7 shows that the two sealing strips 20 and 21 are connected to a T-piece 30 and a double-T-piece 31, respectively.
