Definitions

  • the invention relates to a device for preventing the escape of filling gases during the retraction of coal cakes made in a ramming mold of a ramming, feeding and squeezing machine outside of the coking chamber and standing on the movable ramming base of the ramming mold in horizontal coking chambers, the device being a retracting device Coal cake enveloping channel and formed with the furnace-side end face on the door frame of the coking chamber.
  • a sealing frame enveloping the oven opening and the retracting ramming cake is known, which can be placed in front of the head of the cake to be retracted via a swivel arm from a position laterally next to the ramming mold.
  • the swivel arm in turn is arranged on a carriage which can be moved parallel to the furnace axis, so that it can be moved up to the furnace opening.
  • This known frame does not bridge the entire space between the coking chamber and the tamping mold. Rather, the sealing on the tamping mold side takes place by means of elastic sealing elements which are arranged on the sealing frame and lie directly on the retracting coal cake.
  • a further disadvantage of the sealing elements lying tightly against the coal cake is that in cases where the coal cake sticks and can therefore only be partially inserted, the residual cake is not disposed of, i.e. can be driven back into the ramming device.
  • the coal cake moves back against the setting direction for which the friction seal is designed, there is a build-up of coal at the friction seal, since the coal cake is deformed by the sticking in the coking chamber and no longer forms an exact cuboid.
  • the object of the present invention is to create a simple functional device for preventing the escape of filling gases when coal cakes are inserted into horizontal coking chambers, which avoids these disadvantages.
  • this object is achieved according to the invention in that the side walls of the channel can be moved into the side walls of the ram mold, which are formed as hollow walls in the furnace-side area, that the channel floor is formed by the movable ramming floor and that the channel cover is designed to be telescopic and Has guides for the displaceable side walls, a leveling device smoothing the surface of the coal cake with a disposal device for the scraper coal being arranged on the stationary part of the manhole cover.
  • forced entrainment for example spring-loaded friction surfaces, are provided for retracting and extending the telescopic part together with the side walls of the channel, so that there is no need for a separate drive for the manhole cover.
  • the side walls of the channel can be coupled directly to the movable ramming floor or the ramming floor drive, so that a separate drive can also be omitted here.
  • the side walls are advantageously extended coupled to the tamped floor support.
  • This arrangement has the advantage that the channel side walls and with them the channel cover are already extended and rest on the door frame of the coking chamber before the coal cake itself is placed. As a result, the filling gases that are created when the cake head approaches the hot coking chamber, also supported by the chimney effect, are safely disposed of.
  • the filling gases can be disposed of in a known manner via a gas outlet arranged in the ceiling of the coking chamber and a gas manifold installed above the coke oven battery into a gas treatment system. If the extracted filling gases are burned in a filling gas combustion car that can be moved on the coke oven battery or by transferring them to an adjacent occupied coking chamber, the channel surrounding the incoming coal cake has the further advantage, in addition to the prevention of emissions, that air is not also sucked in uncontrollably through the opened coking chamber with the filling gases , which greatly affects the ignition behavior of the filling gases and can prevent optimal combustion of the filling gases. By sealing the incoming coal cake, the amount of combustion air supplied can be regulated specifically according to the real need.
  • spring-loaded cutting strips are expediently provided, which can also consist of cutting strip segments which can adapt to any unevenness in the door frame.
  • the space between the coking chamber and the SBA machine and next to the SBA machine is not impaired in any way by the device according to the invention.
  • the telescopic manhole cover is in the closed state above the master course in front of the pounding mold, but depending on the cake height at a height of approx. 4-6 m, so that there is no impairment here.
  • a pressure probe can be provided on the manhole cover, which switches off the setting process when the coal cake to be set is blocked under the effect of the pressure exerted by the accumulating coal.
  • an additional gas vent can be provided on the channel.
  • This gas outlet can be connected to the gas manifold which is installed in a stationary manner above the ceiling of the coke oven battery or can be connected to a combustion chamber which is arranged on the SBA machine and can be moved with it.
  • a device for preventing the escape of filling gases during the retraction of a in a ramming device 1 Coal cake 15 produced outside the coking chamber 20 and standing on the movable tamping base 14 of the tamping mold consists of a channel 3 bridging the distance between the coking chamber 20 and the SBA machine 1, which completely surrounds the incoming coal cake 15.
  • the filling gases retained in the channel 3 can be disposed of via a separate gas suction 5 which can be coupled to the channel 3 via a closable connection 25, which, as shown in the example in FIGS. 1 and 2, via connections 6 can be coupled to a gas collecting line 7, the so-called gas receiver, laid above the coke oven battery.
  • a movable gas connection 19 can also be provided.
  • the duct 3 consists of the movable segments duct cover 9, side walls 10 and ramming base 14, which form a unit, in the extended state, a duct.
  • the channel 3 To move the SBA machine 1, the channel 3 must be moved back sufficiently far so that there is a sufficiently wide passage between the anchor stands 26 of the coke oven battery and the SBA machine 1 for the safety of the operating personnel.
  • the side walls 10 of the channel 3 can be moved into the side walls 4 of the ramming mold, which are formed as hollow walls in this area.
  • the manhole cover 9 is telescopic and is in the retracted state above the tamped molding door 21 at a height of approx. 4 to 6 m above the master aisle 23.
  • the retracted channel 3 does not in any way impair the movable tamping molding door 21, the jack bracket lock 22 and the movable door lifting and door frame cleaning device for the coke chamber door (Fig. 4).
  • the side walls 10 of the channel 3 are coupled to the ramming floor support 12 and can thus be moved in and out together with the latter (FIGS. 5, 6, 9, 10). If no ramming floor support 12 is provided, the side walls 10 of the channel 3 can also, e.g. can be coupled to the movable ramming base 14 via driver rollers 13 (FIGS. 12, 13).
  • the telescopic manhole cover 9 is U-shaped. It consists of a narrower stationary part 32 and a wider telescopic part 31.
  • the lateral gap 29 resulting from this on both sides serves as a guide for the movable side walls 10 of the channel 3.
  • the telescopic part 31 of the channel cover 9 is also pushed out via forced entrainment means 16 arranged in the columns 29.
  • the forced entrainments 16 are designed as spring-loaded friction elements.
  • the side walls 10 continue overcoming the frictional forces of the positive entrainment 16 to a stop 27 arranged at the front end of the manhole cover 9, so that it is ensured that the manhole cover 9 seals with sufficient pretension on the door frame 2 .
  • the side walls 10 of the channel 3 are moved in the side walls 4 of the tamping mold with rollers on rails and guided over sliding guides 30.
  • the small gap between the side walls 10 of the channel 3 and the side walls 4 of the Tamping molds are sealed with adjustable strips.
  • the sealing of the channel 3 against the door frame 2 of the coking chamber 20 and the side walls 10 against the ramming floor 14 is carried out via spring-loaded cutting strips 11, which are divided into segments 17.
  • the surface of the incoming coal cake 15 is smoothed by a leveling device 8 attached to the manhole cover 9.
  • the sealing on the top of the cake is carried out by the carbon bead 18 that forms. Excess, stripped coal is disposed of via a pipeline 28.
  • the setting process is interrupted by the pressure acting on the pressure probe 24 due to the coal accumulating in the channel 3.
  • a side wall 4 of the ramming mold To set a mashed coal cake 15, a side wall 4 of the ramming mold must be displaceable by a few millimeters so that the coal cake 15 is relaxed.
  • the side wall 10 of the channel 3 arranged in the movable side wall 4 of the ramming mold thus comes to stand in front of the gap 29 of the correspondingly coordinated channel cover 9.
  • the corresponding side wall 10 of the channel 3 in the upper region with a guide lug 33 is constantly in engagement with the gap 29 of the channel cover 9.
