Definitions

  • the invention relates to a device for sealing the shaft fill opening of a coke oven cooling system with respect to the cooling shaft cover, by means of which the escape of hot dust-laden gases from the cooling shaft into the atmosphere is prevented, the sealing being effected by two sealing elements arranged one behind the other in the direction of flow of the escaping gases and the inner sealing element consists of a seal forming a pre-seal between two steel surfaces.
  • Such devices for sealing the cooling shaft cover which can have a square or rectangular shape, but is preferably round, and can consist of heat-resistant steel or an outer skin made of steel and a heat-resistant lower lining made of insulating material, belong to the prior art.
  • From DE-OS 32 02 645 it is known to use an immersion seal to seal the closure of the filling opening of a coke oven cooler.
  • edge plates are arranged on the lower edge of the cover, which are inserted with their free end into the immersion seal when the cover is placed on the opening. The opposite end of the edge plate is folded over in such a way that a free edge is formed which lies on the edge of the filling opening.
  • closure member known from DE-OS 30 03 374 is formed, which consists of a plate which is provided on its circumference with a downward bar which engages in a dip cup filled with water or sand.
  • the plate provided with fire-proof insulation rests on the mouth of the cooling shaft in the closed position.
  • the invention has for its object to improve the known seals. On the one hand, the operating and manufacturing costs should be reduced and the very maintenance-intensive immersion seals should be avoided; on the other hand, there should be the possibility of coordinating the sealing elements so that a perfect seal is always guaranteed.
  • the invention consists in the fact that the seal between the steel surfaces consists of a peripheral cutting edge, which is attached to the edge of the shaft and projects above it, and a peripheral sealing body and attached to the lower edge of the cover the outer sealing element consists of a soft material seal.
  • the invention further provides that the soft material seal is fastened to the outer peripheral surface of the sealing body with a holder, which contains a section which preferably runs obliquely downward at an angle of approximately 30 °, and yields to a parallel to that when the cover is lowered Section running sealing surface.
  • the soft material seal contains two packs of flexible sealing material, which are seated one behind the other in the flow direction of the escaping gases in U-shaped clamping rails which are attached to the preferably inclined section of the holder.
  • a preferred embodiment of the invention provides that the holder is adjustably attached to the sealing body in such a way that its position relative to the sealing surface can be changed and that the desired position can be fixed by means of locking screws.
  • the fixation of the holder to the sealing body takes place according to the invention in a position in which, after the cover is placed on the shaft opening, a gap with a height of approximately 1 to 5 mm remains between the sealing surfaces of the inner sealing elements, while the packings of the soft material seal with a the complete seal ensures that pressure is applied to the sealing surface.
  • forces can also act on the soft material seal, by which the packings are pressed against the sealing surface.
  • at least one of the sealing surfaces, which effect the seal between the sealing body and the cutting edge is resiliently mounted.
  • the device according to the invention enables a perfect seal with an extremely low maintenance requirement.
  • the adjustable arrangement of the soft material seal on the cooling shaft cover ensures that the soft material seal lies tightly against its sealing surface even after a long period of operation. This is particularly the case if the pre-seal is adjusted so that a gap remains between its sealing surfaces.
  • the shaft (1) of the coke-drying cooling system which is circular in cross-section, consists of an outer steel jacket (2) with an inner lining (3) made of insulating material, the upper edge of which runs obliquely downwards towards the interior of the shaft, in order to prevent deposits of coke particles when the coolant is filled To avoid coke.
  • a support provided with reinforcing ribs that run around forms the horizontal edge section (4).
  • (6) denotes the lid with which the fill opening of the shaft is closed after the coke to be cooled has been filled.
  • a circumferential ring (8) is welded to the outer circumference of the cover body (7) made of steel, and a reinforced sealing body (9) is seated at the lower end thereof.
  • the inner surface of the lid body is provided with a lining (10) made of insulating material. With (11) the lid suspension is designated.
  • FIG. 2 shows an enlarged representation of the section designated by “W” in FIG. 1, from which the arrangement according to the invention for sealing the shaft (1) with respect to the cover (6) results.
  • the arrangement which serves to avoid the escape of dust-laden gases from the cooling shaft into the atmosphere as far as possible, consists of the sealing body (9) and a soft material seal (12) attached to its outer circumference and one on the edge section (4 ) of the shaft, preferably a detachably attached fastening ring (13) with a sealing edge (14) flattened at the upper end and a circumferential sealing surface (15) against which the soft material seal comes to rest.
  • the soft material seal (12) is attached to the sealing body (9) so as to be adjustable in height.
  • (16) locking screws are designated, which are distributed over the circumference and screwed into the cylindrical section (17) of a support reinforced with ribs (21), the section (18) of which extends at an angle of approximately 30 ° parallel to the likewise oblique one Sealing surface (15) extends downwards.
  • Two circumferential clamping rails (19) with a U-shaped cross section are fastened to the section (18) next to one another and accommodate the flexible, easily replaceable sealing material (20) which protrudes from the legs of the clamping rails.
  • the setting of the seal is preferably carried out in such a way that spacers, which have a thickness of, for example, 2 to 5 mm, are placed over the circumference of the cutting edge (14) and the cover is then placed on the shaft opening. After loosening the locking screws (16), the section (17) and thus the entire soft material seal is moved up or down so that the sealing material (20) is sufficiently tight against the sealing surface (15). Then the section (17) of the holder is attached to the sealing body by welding, so that the locking screws (16) can be loosened again.
  • the spacers are removed, so that a gap with a height of about 1 to 4 mm remains between the cutting edge (14) and the sealing body (9), which forms a pre-seal on the one hand and shields the heat radiation and on the other hand ensures that the soft material seal fits snugly against its sealing surface. If, after a long period of operation, it is necessary to check the size of the gap or readjust it, the welds are eliminated and the above processes repeated.
