Definitions

  • the invention relates to a multi-part coke oven door for a horizontal coking furnace with a protective shield serving as a fire shield and a door seal arranged behind it, the protective shield and the door seal being movable independently of one another.
  • Such coke oven doors are known from DE-PS 18 69 34.
  • the protective shield is moved into the oven from above, while the door seal closes the opening of the door frame through which the push rod is moved into the oven or the coke is pressed out.
  • This known coke oven door has so far not been able to establish itself. The reasons for this can be the complicated sealing conditions and the great structural effort.
  • Such coke oven doors are known, for example, from P 33 27 337.5, which relates in particular to a new design of the door body with the associated sealing device.
  • a conventional fireproof door plug is optionally combined according to the design drawings in this document.
  • the known light coke oven door includes a division into a sealing element and a frame structure, the frame structure being kept largely free of thermal stress and the sealing element on the furnace presses frame.
  • the design is essentially determined by the door plug and the associated load.
  • the object of the invention is now to reduce the load on the door body and thereby enable an even lighter construction which, with the same sealing effect, affords further economic advantages.
  • the object of the invention is solved by the characterizing part of the main claim.
  • the invention makes use of the solution known from DE-PS 18 69 34 and has only an apparent disadvantage when the separate protective shield requires an operating mechanism.
  • each machine for coke pressing is not only provided with a door lifting device but also with a door cleaning device.
  • the contamination of the oven door sealing surfaces is so small that the cleaning device can be used to move the separate protective shield.
  • the particular advantage of the construction according to the invention is in particular the complete relief of the door seal from the coal bed standing in the furnace.
  • the door seal can thus almost be designed as a thin film.
  • the protective shield as a so-called hollow profile, which consists of two molded profiles held at a distance from the door body, which are arranged at a short distance from one another, and a vertical gas form the culvert, significant improvements are achieved.
  • an additional gas exhaust duct is formed between the two molded profiles. The gas can enter the gas discharge duct through the lower open cross-section and distributed over the height through slots on the narrow sides between the two shaped profiles and reaches the gas collection space above the coal bed via the upper open cross-section.
  • the protective shield as a hollow profile, a much higher strength is achieved compared to the previously known flat protective shields.
  • the wall thickness of the shaped profiles can be considerably thinner, so that the protective shield according to the invention can be made lighter overall than the previous flat plates with approximately the same bending stiffness.
  • the cost of the protective shield according to the invention is kept very low through the use of standard steel sheet piling in normal design or light profiles or sheet profiles for the shaped profiles.
  • the shaped profiles can be changed by exchangeable spacers which are evenly distributed over the height of the shaped profiles.
  • the gas discharge quantities in the gas discharge duct can be regulated between the two shaped profiles. - It can change the overall thickness of the door plug or the effective coal filling in the chamber. Since the heat radiation from the door body naturally also depends on the thickness of the door plug, a certain desired or permissible temperature can be set on the outside of the door body by changing the spacers between the two shaped profiles.
  • the mean free distances between the two shaped profiles and between the door body and the outer shaped profile can be made in the same or, even if the thickness of the door plug remains the same change opposite senses and thereby optimize the flow conditions in the two gas discharge channels.
  • the sealing plates In order to ensure a correct insertion of the coke oven door with the protective shield according to the invention, it has proven to be advantageous for the sealing plates to move laterally inwards in the longitudinal holes or slots when the shaped profiles are raised. If the lower edges of the sealing plates protrude below the molded profiles in the raised state, they can move towards the chamber walls when the molded profiles are lowered relative to them in a vertical direction and due to the oblique slots or elongated holes. This results in an additional seal against the chamber walls when the door is in use.
  • the sealing plates can be bent over on their vertical longitudinal edges. In a horizontal section through a sealing plate, these can be in particular S-shaped.
  • the inner side of the sealing plates directed towards the center of the chamber bears against the outer shaped profile.
  • the gas can penetrate through the vertical gap between the chamber wall and the inner molded profile into the gas exhaust duct between the two molded profiles, but the raw gas can enter the outer gas exhaust duct between the door body and the outer molded profile due to the sealing of the sealing plates on the chamber walls on the one hand and the outer molded profile on the other hand, penetrate only to a very limited extent.
  • the furnace chamber with the associated heating or chamber walls is indicated by 1.
  • the coke oven door is, e.g. described in P 33 27 337.5 from a door body which runs as a hollow profile along the door frame and is connected to the door frame via locking devices.
  • a sealing plate, 5, 5 a is connected, which is pressed on the periphery of the door frame via spring-loaded screws 4 against the door frame.
  • the sealing plate can be designed as a hollow profile, wherein the hollow profile can be filled with insulation.
  • the sealing plate can be bulged with a one-sided bulge (compare FIG.
  • FIG. 3 shows a number of possible embodiments of the shaped profiles. While the shaped profiles are connected on the outside according to FIG. 1 and surfaces lying in the middle are deflected parallel to the outside, according to FIG. 3.1 the reverse is true, with the profiles in FIG. 3.1 having a small distance in the center and being connected to one another there by the bolts 13. while they are at a large distance from the outside of the chamber walls. According to FIG. 3.1, this distance on the outside can again end on the outside in parallel flat walls.
  • the shaped profiles can also be curved in the form of a circular arc towards the chamber walls or angularly outward according to FIG. 3.6. According to FIG.
  • FIGS. 6 and 7 show the additional sealing plates 24, which are provided with elongated holes 25.
  • FIG. 6 shows the raised state of the shaped profiles in the left half.
  • the sealing plate 25 has separated from the chamber wall 2 and has been pressed inwards and downwards by the compression spring 26. It protrudes below the shape profile.
  • shaped profiles and sealing plates stand on the furnace sole and the sealing plate lies against the chamber wall 2.
  • the relative movement of the shaped profile with respect to the sealing plate can be up to 60 mm, the vertical gap between the shaped profile and the chamber wall being up to 10 mm.
  • FIG. 7 shows the S-shaped shape of the sealing plate 24, the sealing plates being on the inside rest on the outer molded profile 9 and on the outside a vertical narrow gap remains between the molded profile 8 and the sealing plate.
  • a chamber frame 30 is provided instead of the chamber frame 7.
  • the chamber frame 30 has cams 31 on the inside with fork-shaped recesses into which bolts 27 are inserted.
  • the bolts 27 carry the shaped profile 18, 19 which was previously held by the door body 3.
  • this arrangement prevents the coal bed in the furnace from developing its force on the door body 28.
  • the door body therefore only has to withstand the gas pressure in the furnace.
  • the sealing plate 29 can have a minimum thickness, i.e. be designed similar to a film.
  • the door body 28 is - as usual - gripped by the door lifting device and swung back.
  • the shaped profiles 18, 19 are gripped by the door cleaning device provided with corresponding claws on the bolts 27, lifted out of the furnace frame and pivoted back.
  • the door cleaning device is available due to the low tendency to contamination and correspondingly low cleaning activity.
