Definitions

  • the invention relates to a coke entry device for the cooling shaft of a coke dry cooling system, which consists of a stationary funnel with a suction line, a lowerable and lowerable funnel lower part and a movable and liftable and lowerable cooling shaft closure, to which a manipulation device with drive is assigned.
  • the invention has for its object to avoid these disadvantages and to simplify the generic coke entry device, at the same time to shorten the closing process for the movable funnel, to improve the gas flow through the coke bed and to significantly reduce the dust emissions.
  • the distributor bell arranged in the hopper of the coke input device according to the invention avoids separation phenomena in the cooling shaft when the glowing coke is filled. When filling without a distributor bell, segregation occurs in the coke bed of the cooling shaft, which hinders the gas flow.
  • the lateral evasive movement of the funnel lower part which can be moved up and down is eliminated. This reduces the design effort. At the same time, dust emissions are significantly reduced because the bottom part of the funnel, which can be moved up and down, leaves only a comparatively small gap.
  • the funnel acts as a chimney fan due to the suction effect of the blower, so that the lateral intake of false air practically completely prevents dust emissions.
  • FIG. 1 shows a stationary funnel 1, which is displaced in a support structure 7 and to which a lifting and lowering sealing ring 11 is assigned, which is at the same time designed as a lifting and lowering funnel lower part 18 and can be actuated by a drive unit 16.
  • This also serves to raise and lower a distributor bell 5, which is connected to a cross member 39 via a pipe section 40, as can be seen from FIG.
  • the support structures 7 and the drive unit 16 are supported and fastened on a platform 42, which is arranged at the level of the shaft head 51 on a cooling shaft 41.
  • a water cup 10 is provided on the shaft head 51 of the cooling shaft 41, into which the sealing ring 11 projects in the sealing position (FIG. 2).
  • Suction lines 9 are arranged on the stationary funnel 1 (FIG. 2), to which suction fans (not shown here) are connected, which are operated when the hot coke is poured into the cooling shaft 41 in batches, and in the changeover times in which after the distributor bell 5 and Sealing ring 11 or funnel lower part 18, a cooling shaft closure 8 is brought from the rest position (FIG. 4) via a driving linkage 72 by means of rollers or wheels 68 into the sealing position above the cooling shaft 41 (FIG. 3).
  • the cooling shaft closure 8 is inserted, lifted off and moved by means of a manipulator 14 which is arranged on the stage 42. In the sealing position of the cooling shaft closure 8, a sealing ring 55 attached to it is lowered into the water cup 10 (FIG. 3).
  • FIG. 5 shows the water cup 10 filled with water 13, into which the sealing ring 11 is immersed.
  • the connection with the funnel 1 forms a flexible sealing element 12 that is supported against an annular collar 52 of the funnel 1.
  • FIG. 6 shows the drive unit 16 for lifting and lowering the distributor bell 5 and the sealing ring 11 in detail, which in the example is designed as a linear drive.
  • FIGS. 7 to 10 show another design of the lower and lowerable funnel part 18, which is assigned to the stationary funnel 1 displaced on the supporting frame 7 and at the same time also performs the function of a sealing ring 111.
  • the distributor bell 5 is fixedly attached to the lower part 18 of the funnel via the pipe section 40 and the cross member 39.
  • the drive unit 19 for the lower part 18 of the funnel which can be raised and lowered is designed as a double thrust piston transmission, the pistons 71 of which are attached to a crossmember 17 to which the lower part 18 of the funnel is fastened.
  • the drive unit 19 is supported against abutment 70 ( Figure 8).
  • a water cup 10 is shown as a detail in FIG. 11, in the water filling 13 of which the sealing ring 111 fixedly attached to the lower funnel part 18 is inserted in the sealing position.
  • FIGS. 12 to 15 show an embodiment of the coke entry device which differs from that of the object of FIGS. 7 to 10 by an arrangement of the suction line 9 provided in the area of overlap of the stationary funnel 1 with the lower funnel part 18, the structural adaptations to the stationary funnel 1 and condition on the lower part 18 of the funnel, which relate to their external shape, as can be seen in detail in FIGS. 12 to 15.
  • 16 to 18 show an embodiment of the coke entry device with a liftable and lowerable distributor bell 5, which is attached to a crossmember 17, which is guided up and down in guide openings 67 of the stationary funnel 1, which can be closed by sealing plates 34 , which are connected to the traverse 17.
  • the lifting and lowering is carried out by drive units 190, which are attached to the ends of the crossmember 17 (FIG. 17).
  • the stationary funnel 1 is assigned a funnel lower part 18 which can be raised and lowered by a small stroke.
  • this coke entry device has a displaceable funnel 202 and a displaceable cooling shaft closure 800.
  • the displaceable funnel 202 and the displaceable cooling shaft closure 800 are displaced via a common drive. The drive is not shown in the drawing.
  • FIG. 16 shows the sliding cooling shaft closure 800 in the sealing position and the sliding funnel 202 in the rest position.
  • Both the displaceable funnel 202 and the displaceable cooling shaft closure 800 carry on both sides metallic sealing rings 31 which correspond to corresponding metallic sealing rings 31 which are arranged on the shaft head 51 or in the lower region of the lower and lowerable funnel part 18.
  • the metallic sealing rings 31 can be either armored or soft-sealing on their sealing side; cooling is optionally provided.
  • there are nozzle ring lines 32 provided that are supplied with compressed air.
  • the displaceable funnel 202 or the displaceable cooling shaft closure 800 can be guided in cover plates 35 and displaced in a resilient manner. Due to the use of the dry metal to metal sealing principle, practically no openings to the atmosphere through which dust emissions could escape in this area are free during the exchanges of the displaceable funnel 202 for the displaceable cooling shaft closure 800.
  • the lower and lowerable funnel part 18 is configured in two parts in the example and is composed of a pressure ring 330 and a telescopic ring 333.
  • the pressure ring 330 is equipped at the bottom with a metallic sealing ring 31 and at the top with a projection 331, to which a drive 332 is assigned, in the example a thrust piston gear mechanism, the piston 335 of which presses the pressure ring 330 onto the metallic sealing ring 31 of the displaceable cooling shaft closure 800 or the displaceable funnel 202 presses.
  • the telescopic ring 333 is guided in the pressure ring 330 and has a compensator 334.
  • the stationary hopper 1 of the coke entry device can be equipped with a hopper closure 20 which consists of two closure plates 64 and 65, which are shown in FIG. 19 in the open position and in FIG. 20 in the closed position .
  • the closure plate 64 is fastened to a lever linkage 66 which can be actuated via a drive 21.
