Definitions

  • the invention relates to a coke entry device with a housing for a coke dry cooling system, which is assigned to a cooling shaft and consists of a stationary funnel with a suction line, a movable funnel, a movable and liftable and lowerable cooling shaft closure, which is provided with a sealing ring and in a lifting and lowering device is integrated, and there is the housing in which the movable hopper and the cooling shaft closure are housed, which are arranged on a common, movable on rails chassis.
  • the invention has for its object to avoid the aforementioned disadvantages of the generic device and to further develop it in such a way that a seal is provided on the movable funnel and a certain access of false air is made possible in the housing.
  • the movable funnel is provided with a distributor bell and a seal ring which can be raised and lowered and the housing is designed as a hood with floor clearance or with openings in the walls for a limited supply of false air.
  • An expedient further embodiment of the invention provides that the distributor bell of the movable funnel is attached to a piece of pipe which is carried by a cross member.
  • the distributor bell arranged in the movable funnel is attached to a support cross. This configuration allows a low overall height of the movable funnel and the housing.
  • the lifting and lowering sealing ring is preferably displaced in guides and has a lever mechanism on, consisting of lever arms, which are attached to shafts and loaded with counterweights, with guide rollers arranged on the shafts interacting with cam disks for the purpose of raising and lowering the sealing ring.
  • the housing is constructed in two parts, with movable longitudinal and transverse sides being assigned to a fixed hood ceiling, in which the movable funnel and the cooling shaft closure are firmly integrated.
  • FIGS 1 and 2 show a coke entry device according to the invention, which consists of a stationary funnel 1, which cooperates with a movable funnel 2, which is in this illustration in the operating position for charging a cooling shaft 41 with glowing coke below the stationary funnel 1.
  • a distributor bell 3 is arranged, which is attached to a cross member 39 via a pipe section 40.
  • the cross member 39 is anchored in the wall of the movable funnel 2.
  • the glowing coke first comes from a transport container, not shown here, into the stationary hopper 1 and from there into the movable hopper 2, where a uniform coke distribution is achieved with the aid of the distributor bell 3 and thus grain segregation is avoided in the cooling shaft 41, which would otherwise have disadvantages for the Dimensioning and the operation of the cooling shaft 41 would mean.
  • the stationary funnel 1 is supported by a support structure 7 (FIG. 1) which is fastened on a platform 42 which is arranged in the upper region of the cooling shaft 41 around it.
  • a suction line 9 is connected to the stationary funnel 1, with the aid of which the dusts which occur when the glowing coke is introduced are suctioned off in order to avoid dust emissions.
  • Long sides 45 and transverse sides 46 of the hood-shaped housing 6 end above the surface 47 of the stage 42, so that air slots 44 remain, through which air is sucked into the interior of the housing 6 in order to prevent the emission of dust emissions.
  • openings can also be provided in the longitudinal sides 45 and / or transverse sides 46.
  • the housing 6 encloses a chassis 48 which can be moved on rails 49 via wheels or rollers 56 and which on the one hand carries a displacement 59 with the movable hopper 2 and on the other hand a cooling shaft closure 8 and an associated lifting and lowering device 15.
  • the chassis 48 is connected to a drive unit 14, in the example via a telescopic linkage 50, with the aid of which the chassis 48 can be moved from the position shown in FIG. 2 to the position shown in FIG. 3. This happens after a loading process of the cooling shaft 41 with a batch of red-hot coke has ended. Before this process can be initiated, a lifting and lowering sealing ring 11, which is immersed in a water cup 10 filled with water 13 (FIG.
  • the water cup 10 is arranged above the shaft head 51 of the cooling shaft 41.
  • the sealing ring 11 is supported in the sealing position via a flexible sealing element 12 against an annular collar 52 of the movable funnel 2.
  • the movable funnel 2 is moved from its operating position according to FIG. 2 to a rest position according to FIG. 3 and at the same time the cooling shaft closure 8 from its rest position (FIG. 2) into a sealing position (FIG. 3).
  • dust emissions emerging from the cooling shaft 41 remain within the Housing 6 and are suctioned off from there via the suction line 9. The suction process is to be continued until the cooling shaft 41 is sealed with the cooling shaft closure 8.
  • the lifting and lowering device 15 for the cooling shaft closure 8 consists of one or more cross members 53, which can be raised and lowered in guide and lifting elements 54 and moved.
  • the cooling shaft closure After the cooling shaft closure has been moved from its rest position (FIG. 2) to the cooling shaft 41 by actuating the telescopic rod 50, which is shown in the example, it can be lowered into its sealing position via the lifting and lowering device 15 (FIG. 3). At the same time, a sealing ring 55 attached to the cooling shaft closure 8 is lowered into the water cup 10 in order to seal the shaft 41 free of emissions. After the sealing position has been taken up, the extraction of the dedusting lines 9 can be switched off.
  • FIGS. 6, 7 and 8 Another embodiment of the coke entry device is shown in FIGS. 6, 7 and 8. As can be seen from this, it consists of a stationary funnel 100, to which an extension part 57 is connected, which is sealingly surrounded by a housing 600, which is formed from a hood ceiling 430, longitudinal sides 450 and transverse sides 460.
  • the funnel extension 57 corresponds to a movable funnel 200 which is fastened to the chassis 48 by means of a displacement 590 and which contains a distributor bell 4 which is fastened to a support cross 58 which is anchored in the wall of the movable funnel 200.
  • the structure and function of the design of the coke entry device according to FIGS. 6, 7 and 8 essentially correspond to the design according to FIGS. 1, 2 and 3. However, the lower overall heights of the movable hopper 200 and the housing 600 are less material-consuming.
  • FIGS. 9 to 11 A preferred embodiment of the seal ring 11, which can be raised and lowered, is depicted in three dimensions in FIGS. 9 to 11.
  • the sealing ring 11 is guided in rod-like guides 23 and carries retaining tabs 69, on which chains 26 are attached, which lead to one end of lever arms 24 which carry counterweights 25 at the other end.
  • the lever arms 24 are attached to a shaft 29 which are displaced in bearing blocks 60.
  • the bearing blocks 60 are fastened to a chassis 22 which can be moved on rails 62 via wheels or rollers 61.
  • swivel arms 63 At one end of the shafts 29, swivel arms 63 are attached, which carry guide rollers 27 which cooperate with cams 28, as can be seen from FIGS. 10 and 11.
  • the counterweights 25 rest on stops 30.
  • the chassis 22 is moved over the opening of the cooling shaft 41, the guide rollers 27 being raised in the region of the cam disks 28 and, at the same time, the counterweights 25 being raised by rotating the shaft 29, as a result of which the sealing ring 11 is lowered in the sealing position becomes.
  • the sealing ring 11 is raised again by lowering the guide rollers 27 from the cam plate 28 and the chassis 22 returns to its rest position.
  • FIGS. 12 to 14 show a further embodiment of the coke entry device, which is formed by a stationary funnel 101, to which a movable funnel 201 is assigned.
  • a hood ceiling 431 is attached to the stationary funnel 101 as part of a housing 601.
  • the housing 601 still consists of Long sides 451 and transverse sides 461, which are displaceably and sealingly guided on the hood ceiling 431 and which are equipped with wheels or rollers 561, which can be moved on rails 491 and which carry the funnel 201 and the lifting and lowering device 15 for the cooling shaft closure 8 .
  • the telescopic linkage 50 of the drive unit 14 is attached to one side wall 461, with the aid of which the movable part of the housing 601 can be moved.
  • FIG. 13 shows a position of the housing 601, in which the movable funnel 201 is shown in the operating position and the lifting and lowering device 15 for the cooling shaft closure 8 is shown in the rest position.
  • FIG. 14 shows a position of the housing 601 in which the lifting and lowering device 15 with the cooling shaft closure 8 is arranged in a sealing position above the cooling shaft 41 and the movable funnel 201 has assumed its rest position.
  • the stationary hopper 101 is equipped in this embodiment of the coke entry device with a hopper closure 20 which is formed by two closure plates 64 and 65.
  • the actuating device of the funnel closure 20 is shown in FIG. 15. In the example, it is formed by a lever linkage 66 and a drive 21.
  • the funnel closure 20 contributes to a further reduction in dust emissions in that the cooling shaft closure 8 can already be opened when the stationary funnel 101 is closed before the container with the glowing coke has been placed on the stationary funnel 101. After the cooling shaft 41 has been loaded, the loading container can be lifted off earlier after the funnel 101 has been closed, without the dust emission suction system being excessively loaded by the suction line 9 due to too much false air suction.
