Definitions

  • the invention relates to a coke oven door with a ceramic shield structure, which is arranged at a distance from the actual door body to form a gas collecting space, and to the plates and stones used for this purpose.
  • the door stopper or shield structure consists of several superimposed front panels, each of which is held in a steel frame connected to the front panel, each steel frame being held at a distance from the coke oven door by three carrying arms.
  • Each steel frame has retaining anchors which are molded into the ceramic plate as connecting elements. In view of the heat load that occurs, the fastening of the ceramic plates by means of the holding anchors and steel frames is not to be considered an advantageous solution.
  • a gas collection channel made of special U-shaped plates made of refractory material is provided.
  • the U-shaped plates shown are very complex to manufacture.
  • the invention has for its object to improve the ceramic shield structure of a coke oven door so that a secure attachment of easily replaceable, easy to manufacture front panels is achieved without any fastening parts made of metal or complex recesses for special mounting elements in the ceramic plates in the manufacture of these front panels have to be molded.
  • the object is achieved according to the main claim in that releasable, claw-like mounting elements engage on narrow opposite side surfaces of flat front panels.
  • the side surfaces have indentations or profiles of a cross section that is constant over the length of the side surfaces, preferably in the form of grooves with a U-shaped cross section with a rounded bottom surface.
  • the retaining elements engage in this groove, and are preferably designed in the region of the contact surfaces of the plates in their shape to match the shape of the groove, in particular in the form of round or semicircular profiles.
  • the plate is held by the pressure forces exerted by the mounting elements.
  • This type of fastening of the front panels complies with the strength properties of the ceramic and refractory materials, which can easily withstand the pressure required here.
  • the front panels are preferably produced in an extrusion process.
  • the grooves formed in the side surfaces result from the suitably shaped cross section of the extrusion die. After extrusion, the sheets are cut to the desired length and only dried and fired.
  • the carrying iron can be made of cast iron or of a heat-resistant or heat-resistant steel.
  • the cross section of the carrying iron has a shape that is suitable for fastening the holding elements, for example an angular, circular or oval shape.
  • the surface protruding between the adjacent front plates supports this, whereby the round iron engaging in the groove prevents displacement.
  • the round bar arranged on the parallel surface exerts a pressure force on the lower plate and holds it in place.
  • the parts carrying the round iron pieces are sufficiently elastic to compensate for thermal expansion of the ceramic plate.
  • a gap remains between two adjacent plates, which is closed by a mat made of heat-resistant fibrous material and is so large that a front plate can be removed from the shield structure after the screw connection has been loosened.
  • the front panels are preferably made of a ceramic material with a low coefficient of expansion and high resistance to temperature changes.
  • a cordierite-containing material is preferred as such a material.
  • the ceramic front plates are provided on their side facing the coal with a dense glassy coating, the thermal expansion of which is adapted to that of the material of the plate and which prevents undesirable graphite formation on the surface of the plate.
  • heat-insulating light stone elements are arranged on the door body on its side facing the intermediate and gas collecting space.
  • a fiber mat can be inserted between the lightweight stone elements and the door body.
  • the light stone elements are expediently provided with recesses for the passage of the carrying iron. They preferably consist of temperature-resistant materials with a low coefficient of expansion. Ceramic materials containing cordierite are preferably also used here.
  • Fig. 1 shows a coke oven door with the door body (1) and to be attributed to the shield structure, one above the other, flat front panels (2), which are attached at a distance or space (6) to the door body by means of holding iron (3).
  • Light stone elements (4) are arranged on the door body to insulate it, a preferably ceramic fiber mat (5) being inserted between the light stone elements (4) and the door body.
  • a gap (7) remains between two front plates (2), which can be closed by a mat made of heat-resistant fiber material, not shown.
  • Grooves (23) are arranged on the upper and lower sides of the ceramic plates (FIGS. 4 and 5), into which holding elements (11 and 13) engage in a hook-like manner.
  • These mounting elements are attached to the carrying iron (3).
  • brackets (17, 18) are attached to the carrying iron (3), which support the front plates (2) and the light stone elements (4).
  • the light stone elements (4) have recesses through which the carrying iron (3) run.
  • a surface (12) extends from the support iron (3), which is designed here as an angle profile, at the end of which a piece of round iron (11) is welded, which into the groove (23) on the lower narrow side ( 22) engages the upper front plate (2).
  • the underside of the front plates (2) has a recess (24) (FIG. 4) for the surface (12).
  • a part (14) is arranged approximately parallel to the surface (12).
  • the round iron piece (13) located at its end engages from above into the upper groove of the lower plate (2).
  • a round bar (16) is arranged between the parts (12, 14) and welded to the part (14), for example.
  • the front plate (2) to be replaced can then be tipped forward and / or lifted off the lower round iron pieces (11).
  • the gap (7) is so wide, at least in the part facing the intermediate space (6) and along the length of the round iron pieces (11, 13), that a plate (2) can be removed.
  • a further bar (29) can be attached to the part (12), but its height is lower than that of the round bar (16).
  • the rod (29) secures the part (14) with the round rod (16) against displacement in the direction of the interior of the furnace, so that the plate in question also breaks if the screw connection (15) breaks cannot easily tip out.
  • the rod (29) also serves to center the part (14) during assembly. If necessary, another rod on the other side of the round rod (16) can facilitate centering during assembly.
  • the uppermost of the front plates (2) is held by a part (14a) with a piece of round iron corresponding to the part (14), but here the part (14a) by means of a corresponding screw connection on a holding iron (3) only down to the top of the Front plate (2) is pressed.
  • the distance (d) is dimensioned such that by loosening the screw connection (15) (Fig. 3) and folding up the part (14) (Fig. 3) until the part (14) against the surface (12) (Fig 3) is applied, the mounting element (13) (Fig. 3) is moved out of the groove (23) so far that the front plate (2) can be tilted in the direction of its front surface and lifted out.
  • one leg of the approximately U-shaped cross section can be inclined in a suitable manner against the second leg.
  • the carrying iron (3) can also be made in several parts in a known manner, so that the width of the space can be adjusted as required.
  • the carrying iron consists of cast round profiles.
  • the mounting elements and / or the mounting brackets or corresponding surfaces consist of cast iron.
  • 6 and 7 show carrying iron (30) of a different design.
  • upright flat irons such as stirrups or semicircles, are used, supporting the front plate (2) towards the intermediate space (6) in its central part.
  • the surface (12) is welded on, which at the same time stiffens the corners and creates a connection to the brackets (17).
  • the part (14) is located below the surface (12) in the arrangement shown in FIG. 3.
  • Fig. 6 also shows another embodiment of the front panels (2), the vertical narrow sides (25), which here connect at an angle greater than 90 degrees to the front side facing the coal.
  • the conical design can advantageously be produced by the cut when the extruded profile is cut to length.
  • the choice of material containing cordierite for the ceramic front plates, which form the shield plate, results in a low expansion coefficient, so that the edge gaps to the masonry surrounding the door can also be chosen to be smaller than, for example, metal shields.
  • the lightweight stones (4) used to isolate the door body (1) can consist of specially made lightweight stone elements with recesses which are adapted to the cross-section of the carrying iron for the carrying iron (3,30), or the insulation is built up from standardized formats.
  • the front panels produced according to the invention in the extrusion process have a ceramic structure which is improved by the extrusion with the subsequent drying and firing.
  • the support elements provided, for example in the form of the round iron pieces (11, 13) shown, avoid thermal stresses between ceramic and metallic material. They also make it very easy to replace individual front panels.
  • the size of the ceramic front plates used according to the invention was approximately 80 mm in thickness, approximately 450 mm in height and approximately 500 mm in width, with a total height of the plates arranged one above the other of more than 4,000 mm .
  • the dimensions of the panels depended on the dimensions of the oven door. Other dimensions are easily possible.
  • the shield structure according to the invention is not only advantageous for coke oven doors, but can also be used with other industrial oven doors with and without a gas channel.
