Definitions

  • the invention relates to a coke bucket with a closure which covers the receiving space for the coke to avoid emissions during the transport of glowing coke to a coke cooling shaft and has a connecting piece which is connected to a suction line during the emptying of the coke into the cooling shaft.
  • the so-called coke dry cooling means continuous cooling of the red-hot coke in a cooling shaft, the red-hot coke being cooled in each case by inert gases and possibly the cooled walls of the cooling shaft without giving off emissions.
  • the glowing coke is transported from the coke oven to the cow device with the help of a coke bucket, raised and then placed on the cooling shaft and emptied by actuating the bottom flap.
  • the transition area between the coke bucket and the cooling shaft is encapsulated and this area is connected to a suction line.
  • DE-A 30 04 175 also discloses a device for the transport of glowing coke from the furnace chambers to a stationary extinguishing station by means of a container trolley which can be covered with a lid, suction devices for the dirty gases arising during the emptying of the coke into the extinguishing station Transfer funnels are provided.
  • a disadvantage of this is the design of the closure, because the connection piece protrudes like a gallows and it can therefore easily slip and damage the closure, for example by bumping.
  • the invention has for its object to simplify the transport of the glowing coke while protecting the environment and to create a suitable coke bucket with a closure.
  • the closure thus remains in the shaft structure when the emptied coke bucket is moved to a new coke oven via the fire-fighting track. If the coke bucket filled with glowing coke comes back and drives into the shaft frame and is lifted off the fire-fighting track, it takes the lock with it and is now shielded from the atmosphere until it is emptied and deposited on the fire-fighting track. A separate work process and a special device are therefore not required for lifting or putting on the closure, which leads to a simplification of the process without the environment being significantly burdened thereby. At the same time, the transport of the coke bucket is simplified because the bulky lock remains inside the shaft structure so that when a new filled coke bucket approaches it is immediately put back on it.
  • the released gases can advantageously be prevented from escaping into the atmosphere by first collecting them largely during the process of the coke bucket and sucking them off after placing them on the cooling shaft.
  • a suitable design of the coke bucket or its closure creates a cavity which is sufficient to accommodate the gases released in the shaft structure during the movement of the coke bucket, without the risk that they escape into the atmosphere through any leaks due to the internal pressure.
  • the existing cavity and the entire interior of the coke bucket are then connected to the suction line and the gas present is continuously extracted. In this way, effective environmental protection is ensured without the need for special brackets or loading weights to be provided for the closure.
  • the method is carried out with the aid of a coke bucket with a closure which covers the receiving space or the interior of the coke bucket and has a connecting piece which can be coupled to the suction line.
  • a closure is detachably placed according to the invention on the edge of the coke bucket and is designed to seal the interior from the atmosphere and has longitudinal beams projecting beyond the edge on two sides.
  • Such a closure has a comparatively low weight, is therefore easily placed on the upper edge of the coke bucket when the coke bucket is lifted, and on the other hand is placed at a suitable point via the side members protruding in the shaft frame, in such a way that the next filled coke bucket automatically moves underneath again. is raised and takes the lock with it.
  • the closure is convexly curved and that with the connecting piece equipped suction pipes are set deep in the bend.
  • a tight seal of the suction line under vacuum and the connection piece is achieved according to the invention in that the suction line has a water cup seal corresponding to the connection piece.
  • the suction line has a water cup seal corresponding to the connection piece.
  • suction line is fork-shaped at the end for connecting two suction pipes and has a pipe socket in this area which can be closed by a flap coupled to the flaps. Cool fresh air is sucked in through this pipe socket with flap, so that the exhaust gases in the actual suction line have such a low temperature that they can then be effectively dedusted in a cloth filter.
  • the large gas collecting space available has an inhibiting effect on gas leakage from the closed coke bucket.
  • the suction pipes have automatically opening closure flaps when the coke bucket is put on. Such flaps prevent gases from escaping during the process of the coke bucket, while the flaps open automatically when the connection to the suction line is established via a corresponding lever linkage and relief weight. This effectively prevents gases from escaping from the suction pipes and entrainment of dust particles.
  • closure is formed from the outer longitudinal members and cross members on which the insulating materials carried by a cover plate via anchors are arranged.
  • Such a closure can advantageously be light due to the design described, which has a very advantageous effect due to the otherwise very large coke bucket parts to be lifted and transported.
  • the longitudinal beams are designed as double T-beams and projecting over the closure and are connected to the cross beams.
  • the protruding longitudinal members form a stable closure shelf, it being advantageous to make the closure flat in the edge region and parallel to the longitudinal members and only convexly curved in the central region.
  • the side members, which carry the lid or fastener, are connected to the cross members and the cover plate.
  • the invention is characterized in particular by the fact that a method is created with which an effective closure of the coke bucket is provided in the important phases without the transport being made difficult thereby.
  • additional lifting and moving devices for the closure in the area of the coke ovens can be dispensed with.
  • Also advantageous is the light design of the closure and thus the ease of handling and sealing on the one hand with respect to the coke bucket itself and on the other hand with respect to the suction line.
  • the coke bucket 1 shows a coke bucket 1 as it is moved within the shaft frame 2 after it has been lifted from the trolley.
  • the coke bucket 1 hangs in a gripping plate 3, the hooks of which are pivoted behind the gripping cams 4, so that the bucket assumes a sufficiently stable position during the movement within the shaft frame 2.
  • the interior 7 of the coke bucket 1 is, as mentioned, designed so that it can hold up to 40 t and more glowing coke.
  • the resulting gases are largely collected within the shaft frame 2 during the process and then continuously sucked off and passed into the suction line 6, which is indicated in FIG. 2.
  • the closure 10 covering the coke bucket 1 has a connecting piece 9 projecting laterally. When the coke bucket 1 is lowered onto the cooling shaft, the connecting piece 9 approaches the suction line 6 until the water cup seal assigned to the suction line 6 takes effect.
  • the closure 10 consists, as can be seen from FIGS. 1 to 3, of the cover plate 11 arranged below the cross member 12 with the insulating material 13 and the longitudinal members 14, 15.
  • the edge region of the closure is designed so that it has a sufficient support the edge 16 of the coke bucket 1 ensures.
  • the longitudinal members 14, 15 are formed cantilevered over the sides 17, 18 of the coke bucket 1 and thus serve as a lid shelf or closure shelf. 3, they are connected to the short cross members 28, 30, while the cross members 12, 29 arranged in the convex configuration of the closure 10 are connected to the longitudinal members 14, 15 via vertical stems 31 .
  • the suction pipe 20 or the suction pipes 20 are connected in the bow deepest 21, so that a uniform and safe suction with a low suction speed is ensured as soon as the connection between the suction line 6 and the suction pipe 20 or connecting piece 9 is established.
  • the suction pipes 20 have a rectangular cross-section and can be closed with flaps 22, so that during the movement of the coke bucket 1 inside the shaft structure 2, the gas escape from the suction pipes 20 into the atmosphere is considerably more difficult.
  • Fig. 3 illustrates that the convex design of the closure 10 remains limited to the central region 26, while the edge regions 24, 25 run flat, so that the arrangement of the longitudinal beams 14, 15 is inexpensive to accomplish.
  • the closure flaps 22 and the suction pipes 20 are indicated, via which dust-containing gas, which is present in the cavity formed by the convex design of the closure 10, is sucked off.
  • Fig. 4 shows the connection between suction line 6 and connecting piece 9 or suction pipes 20.
  • the flaps 22 are arranged, which are automatically opened via the counterweight 33 and lever linkage 34 when the coke bucket 1 is placed on the cooling shaft. After the coke bucket 1 has been lifted off, the closure flaps 22 are then placed again so that they make it much more difficult for gases to escape from the interior of the coke bucket.
  • connection between the connecting piece 9 and suction line 6 is sealed via the water cups 32, while the closure 10 itself only rests on the edge 36 of the coke bucket 1.
  • both connecting pieces 9 to the suction line, this is fork-shaped at the end in the form of a U-piece 38. Both connecting pieces 9, 9 'are thus evenly connected to the suction and dedusting.
  • a pipe socket 39 is formed, which can be closed by a flap 40. This flap is opened during the suction process, so that cool and fresh air can flow in and thereby cool the gases extracted from the coke bucket 1. This makes it possible to dedust the extracted gases at the end of the suction line 6 via a cloth filter.
  • the flap 40 is opened to a greater or lesser extent, depending on the amount of gas and the gas temperature.
