Definitions

  • the invention relates to a device as a closure of the filling hole of a coke oven chamber, which device is designed as an inner frame for a closure lid, and this frame is rotatable both against the closure lid and against an outer frame, and the frame is asymmetrical against a vertical plane, such that the closure lid is displaced along a longitudinal axis upon rotation of the inner frame in the horizontal plane.
  • the coking of coal is typically carried out cyclically.
  • the coking is carried out so that a coke oven chamber suitable for coking is loaded with coal, which is then closed, the coal is coked by heating to coke, and the finished coke is then expressed from the coke oven chamber.
  • the loading of the coke oven chamber is in some embodiments through the openings of the coke oven chamber of the coke oven chamber. Other embodiments in turn are loaded through the ceiling of the coke oven chamber. The choice of the particular embodiment is usually left to the person skilled in the art.
  • Embodiments of coke oven chambers which are loaded by the blanket with coking coal are well known in the art.
  • the DE 19743868 A1 describes a charcoal filling car for filling coking chambers of a coke oven battery, with a funnel-shaped bottom outlet, a horizontal screw conveyor below the bottom outlet and a lid lift-off device for opening and closing filling hole covers of the coking chambers.
  • the housing of the screw conveyor is arranged to be horizontally movable on the underside of the coal filling carriage, and by means of an actuator with an unchanged location of the filling carriage between a starting position and a filling position movable. In the initial position, the outlet is positioned laterally to the filling hole.
  • ceiling loading eliminates the equipment cost, which is otherwise required for loading in front of the coke oven chamber.
  • loading machines are usually required, which are elaborately dimensioned and need space in front of the coke oven chamber. This effort is eliminated in the ceiling loading, but in the ceiling loading accurate positioning of the coal filling machine on the filling hole is necessary.
  • the filling holes are designed to isolate the coke oven chamber usually with a small cross-section to keep the heat loss of the coke oven chamber through the coke oven chamber ceiling low. Also, smaller fill holes in the coke oven chamber ceiling can keep emissions low.
  • the filling holes are made by structural measures, such as a Umschalung by a refractory material, firmly integrated into the coke oven chamber ceiling.
  • a Umschalung by a refractory material firmly integrated into the coke oven chamber ceiling.
  • the result is a change in the position of the filling holes in the coke oven chamber ceiling, which makes automation of the filling difficult.
  • the coal filling machines therefore have to compensate for the change in the positions of the filling holes.
  • SU 1468909 discloses a fill hole closure consisting of an inner circumferential frame and an outer circumferential frame, the inner frame being symmetrical with respect to a vertical sectional plane.
  • a typical method and apparatus for charging coke ovens of a coke oven battery through the ceiling with compensation for the positioning of the fill holes teaches DE 10145431 C2 ,
  • the teaching claims a method for charging coke ovens of a coke oven battery, in which a KohleSchhorn on the oven ceiling in the longitudinal direction of the coke oven battery and positioned to fill the coke ovens at predetermined locations, with horizontal positional deviations of the Grelochrahmen measured from a basic position in the longitudinal and transverse directions and and an operation unit comprising the filling telescope, a lid lifter and a frame cleaner adjustably connected to the coal hopper at the coal hopper is placed in a position associated with the actual position of the fill hole frame according to the stored values, and from this position the lid lifter , the frame cleaner and the filling telescope are moved to their respective working positions.
  • the teaching is thus similar the deviations from the original position of the filling hole, which result in the course of operation of a coke oven chamber, by a changed positioning of the filling machine during
  • the equipment required for this measure is considerable. For this reason, it is often over, instead of the position of the filling machine to change the position of the filling hole and to put this largely back in the original arrangement.
  • the filling hole must be removed from the structural opening of the coke oven chamber ceiling and processed the material of the coke oven chamber ceiling. This is usually possible only during an interruption of the operation, resulting in increased operating costs and a deteriorated economy of the process.
  • the invention solves this problem by an adjustable Greedvant for insertion into a filling opening for filling the coke oven chambers of a coke oven battery
  • said Artlochrus consists of the components filling openings, Bilochver gleich and Bilochdeckel
  • the ArtlochverInstitut consists of an inner frame and an outer frame
  • the Artlochdeckel is stored by a suitable construction in the inner frame of the ArtlochverInstitutes, and the inner frame of the MedlochverBankes against both the outer frame and the Golflochdeckel is rotatable, and the inner frame is constructed asymmetrically, so that located in the inner frame opening, the for the Bilochdeckel is provided, shifts when turning the inner frame in the horizontal direction.
  • the asymmetry of the inner frame of the Grelochdeckels can typically be achieved in that it has no exactly round shape.
  • the inner frame is shaped so that the outer periphery of the inner frame is asymmetrically shifted against the inner periphery of the inner frame, whereby their corresponding circles do not coincide with their geometric centers.
  • the deviating from the round shape frame then takes on the round Grelochdeckel so that it is displaced upon rotation of the inner frame. Although this shift is usually only a few centimeters, this is sufficient to compensate for the shift for another period of operation.
  • the material of the device components can be designed arbitrarily, but must be such that it withstands the high temperatures that prevail on the ceiling of the coke oven chamber.
  • the outer frame is designed in one embodiment of a refractory mineral material.
  • the inner frame is designed in one embodiment of a refractory mineral material.
  • the refractory mineral material in one embodiment is ceramic or firebrick.
  • the outer or inner frame or both frames are in a further embodiment made of cast iron or a high temperature resistant steel.
  • the high temperature resistant steel or cast iron should be resistant to at least 800 ° C. This applies to the entire construction of the GulochverInstitutes and the surrounding structural measures and the Grelochdeckel.
  • the choice of material is also left to the person skilled in the art to the effect that he will not choose any material that does not withstand the conditions on the coke oven chamber ceiling. For this reason, for example, he will not choose any material that already softens or becomes brittle at 800 ° C.
  • the material must be such that this ensures both the high temperatures on the coke oven chamber ceiling and a rotatability of the Grelochdeckels against the inner frame and a rotatability of the inner frame against the outer frame.
  • the outer frame is advantageously integrated firmly into the ceiling of the coke oven chamber.
  • the structural measures are an example of incorporation with a mortar.
  • the DE 2942805 A1 describes a lid for tightly closing an opening leading into a coke oven, which has an inner surface and an outer surface, wherein the lid body is associated with a sealing edge, which can engage with the bevelled edge surface of the lid and forms a primary seal for the lid.
  • the DE 2732245 B1 describes a closure device for a filling hole of a coke oven chamber with a filling hole cover inserted into a frame, wherein the structural components of the lid and the frame and the lid, which anchor these into one another, are sealed against each other by a displaceable, powdery material.
  • the devices mentioned do not disclose any possibility of allowing a shift of the cover in the horizontal direction by a simple method step. This is the case with the present invention.
  • Both the outer frame and the inner frame of the present invention have holding devices by which the inner frame is receivable in the outer frame.
  • These are, for example, beveled circular surfaces as peripheral edges of the frames, wherein a circular surface in the inner curve of the outer frame is beveled and upwardly disposed in the frame, and another bevelled surface in the outer curve of the inner frame and upwardly outwardly building is arranged. These then interlock when inserting the inner frame.
  • the Grelochdeckel can be supported arbitrarily against the inner frame.
  • These are, for example, beveled circular surfaces as peripheral edges of the frames, wherein a circular surface in the inner curve of the outer frame is beveled and upwardly disposed in the frame, and another bevelled surface in the outer curve of the inner frame and upwardly outwardly building is arranged. These then engage each other when inserting the Golflochdeckels.
  • the holding device can however be of any kind. This can be an example of a ring nose, which engages in an annular channel, as in the DE 2732245 B1 is shown. This can also be done for the inner against the outer frame so.
  • the filling opening in the coke oven ceiling shifts so that it can be moved by simply rotating the frame and thus the filling hole opening for the coal filling machine remains accessible without repositioning.
  • the twisting of the inner frame can be done both manually and by a mechanism.
  • the filling hole cover is used after completion of the filling process again in the inner frame.
  • the outer and inner frames can be sealed against each other.
  • the inner Gulochrahmen and Greeckel can be sealed against each other by a sealing material.
  • sealing material can be used by way of example a sealing cord or a sealing mat. But it can also be used a fillable or lubricious sealant. This can be an example of sand.
  • the filling of the frame or the Grelochdeckels with the sealant can be done manually, for example. But this can also be done by a refill mechanism, as this example in the EP 1002850 B1 is taught.
  • the invention can be used in any type of coke oven chamber.
  • the device according to the invention can be used singly or multiply or also in combination with filling openings of the prior art.
  • the apparatus according to the invention can be used in coke oven chambers arranged in coke oven benches of the "heat recovery” or “non-recovery” type, but it can also be used in coke oven chambers arranged in coke oven batteries of the conventional type.
  • the invention has the advantage of enabling an adjustment of the arranged on the ceiling of a coke oven chamber filling hole for coal, so that the deviation from the original arrangement of the filling opening, which results in the course of operation by the environmental pollution and the inflow of impurities of the coke oven chamber through simple twisting of a component is made possible.
  • a repositioning of the coal filling machine as a correction to the deviation of the filling opening or the filling openings from the starting position is not required or the deviations of the filling opening from the starting position can be better compensated by the Koksofenbedienmaschine.
