Definitions

  • the invention relates to a coke entry device for the cooling shaft of a dry coke 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 a drive is assigned.
  • the distributor bell arranged in the funnel of the coke entry 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.
  • FIG. 1 shows the coke entry device in a side view with a laterally arranged lifting and lowering device for the lower funnel part with distributor bell;
  • Figure 2 shows the subject of Figure 1 in a front view in the filling position with the lower funnel lower part and distributor bell;
  • FIG. 3 shows the subject of FIG. 1 with the lower part of the funnel and distributor bell raised, and the funnel closure in the closed position and with a manipulator;
  • Figure 4 shows the subject of Figure 3 with funnel closure in the rest position
  • Figure 5 is a detailed drawing of the lifting and lowering sealing ring of the funnel lower part
  • FIG. 6 shows a detailed drawing of the distributor bell and the sealing ring with lifting and lowering device
  • Figure 7 another embodiment of the object of 8, 9 Figures 1 to 4 with modified lifting and lowering and 10 device and modified sealing ring for the lower part of the funnel and distributor bell;
  • FIG. 11 shows a detailed view of the lower funnel part with a sealing ring
  • FIG. 12 shows a further embodiment of the subject of FIGS. 13, 14 FIGS. 7 to 10 with a modified stationary and 15 funnels and a lower funnel part with a distributor bell;
  • FIG. 16 shows, in two views, a further embodiment of the and 17 coke insertion device with a modified stationary funnel and a subdivided lowerable, lowerable and easily movable funnel lower part and with dry metal seals;
  • Figure 18 is a detailed drawing of the object of Figures 16 and 17 in the sealing area
  • Figure 19 shows a closure device for the stationary and 20 funnels in the open and closed position
  • FIG. 21 shows an actuating device for the subject of FIGS. 19 and 20.
  • 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.
  • 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.
  • 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, which 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 embodiment 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. In the raised position (FIG. 9) there is sufficient space to manipulate the cooling shaft closure 8 from its rest position (FIG. 10) via the shaft head 51 of the cooling shaft 41 and to lower it there into its sealing position.
  • 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 let into the sealing position.
  • FIGS. 12 to 15 show an embodiment of the coke feeding device which differs from that of the object of FIGS. 7 to 10 by an arrangement of the suction line 9 in the area of overlap of the stationary funnel 1 with the funnel lower part 18 ⁇ separates, the constructive adjustments to the stationary funnel 1 and the lower funnel part 18, which relate to their outer shape, as can be seen in Figures 12 to 15 in detail.
  • FIGS. 16 to 18 show an embodiment of the coke feeding device with a lifting and lowering distributor bell 5, which is attached to a crossmember 17, which can be moved up and down in guide openings 67 of the stationary funnel 1, which pass through Sealing plates 34 can be closed, which are connected to the crossmember 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.
  • the displaceable cooling shaft closure is shown in 800 'and sealing position of the movable hopper 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, if necessary cooling is 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.
  • the lower and lowerable funnel part 18 is designed 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, the piston 335 of which presses the pressure ring 330 onto the metallic sealing ring 31 of the sliding cooling shaft closure 800 or the displaceable funnel 202.
  • 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 are shown in the closed position.
  • the closure plate 64 is fastened to a lever linkage 66 which can be actuated via a drive 21.
  • Distribution bell can be raised and lowered
