Description
2 ~ oo~~o A COKE-CHARGING SYSTEM FOR A COKE DRY-COOLING PLANT
The present invention relates to a coke-charging system for the cooling shaft of a dry-cooling plant that comprises a stationary hopper with a suction line, a hopper lower section that can be raised and lowered, and a cooling shaft shutter that can be moved and raised and lowered, to which a manipulating device with a drive system is associated.
In this system, which is described in DE-PS 25 53 386 it is a disadvantage that when the cooling shaft is being charged with the incandescent coke, grain separation takes place and this leads to a disadvantageously uneven passage of gas through the coke bed within the cooling shaft. In this system, it is also a disadvantage that the hopper which can be raised and lowered is additionally configured so that it can be manipulated laterally and, together with the cooling shaft shutter, is arranged on a common chassis, for such an arrangement takes up a comparatively large amount of space.
It is a particular disadvantage of this charging system that when the cooling shaft shutter is raised and when the hopper, which can be moved into and out of position, is moved to one side, dust emissions can escape past the stationary hopper to the atmosphere until such time as the hopper shutter has assumed its sealing position.
It is a task of the present invention to avoid these disadvantages, to simplify a coke-charging system of this kind and simultaneously shorten the closing procedure for the movable hopper, to improve the flow of gas through the coke bed, and effect a considerable reduction in dust emissions.
a Z ~ ooalo In a coke charging system of this kind, this problem has been solved by the combination of a coke-feeding device and a cooling shaft having a mouth provided with an upwardly open water filled lute of a dry cooling apparatus for coke, said coke-feeding device comprising: a stationary hopper positioned above said cooling shaft and provided with a suction line for drawing gas from said hopper; means forming a vertically movable sealing ring having a downwardly extending perimetral sealing rim adapted to dip into said lute in a lowered position of said sealing ring; a cooling shaft closure overlying said mouth of said cooling shaft below said hopper and liftable from and lowerable onto said mouth of said cooling shaft, said closure having a downwardly extending collar engageable in said water-filled lute; a manipulating drive connected to said cooling shaft closure for lifting said closure with said collar from said water-filled lute, laterally withdrawing said closure from beneath said hopper and above said mouth, reinserting said closure below said hopper and above said mouth and lowering said closure with said collar projecting into said water-filled lute; a distribution bell in said hopper vertically movable with said sealing ring; and a bell and seal drive operatively connected to said bell and to said sealing ring for simultaneously raising said bell and said sealing ring, thereby lifting said sealing ring out of said water-filled lute, and lowering said bell and said sealing ring whereby said sealing ring extends into said water-filled lute.

The distributor cone that is arranged within the hopper in a coke-charging system of this kind prevents the occurrence of separation when the incandescent coke is being charged into the cooling shaft. If the coke is loaded into the cooling shaft without a distribution cone, separation takes place in the coke bed of the cooling shaft and this can hinder the passage of gas through the coke bed.
In addition, in the coke-charging system according to the present invention, with the exception of the variants in which, for all practical purposes, lateral movement without emissions is made possible because of the dry metal-to-metal sealing principle, there is no lateral movement of the lower section of the hopper that can be moved into and out of position. This reduces construction costs. At the same time, dust emissions are greatly reduced because the lower section of the hopper that can be moved into and out of position leaves only a comparatively small gap open. For the remainder, because of the suction effect of the fan, the hopper acts as a smoke trap, with the result, for all practical purposes, that the lateral induction of infiltrated air prevents duet emissions completely.
The present invention will be described in greater detail below on the basis of the drawings appended hereto.

Figure 1 shows a stationary hopper 1 that is supported in a supporting structure 7, with which a sealing ring 11 that can be raised and lowered is associated, and which is simultaneously configured as a hopper lower section 18 that can be raised and lowered, and which can be actuated by a drive unit 16. This simultaneously serves to raise and lower a distributor cone 5 that is mounted on a transverse support 39 through a section of pipe 40, as can be seen in figure 2. The supporting structure 7 as well as the drive unit 16 are supported on and secured to a platform 42 that is arranged at the same height as the shaft head 51 on a cooling shaft 41. A water trough 10 is provided on the shaft head 51 of the cooling shaft 41 and a sealing ring 11 extends into this in the sealing position (figure 2). Suction lines 9 are arranged on the stationary hopper 1 (figure 2), to which exhaust fans (not shown herein) are connected; these fans are run when the hot coke is loaded, charge by charge, into the cooling shaft 41, and they are also operated during the change-over periods during which, after the distributor cone 5 and the sealing ring 11 or the lower section 18 of the hopper, respectively, have been raised, a cooling shaft shutter 8 is moved from the resting position (figure 4) by a travelling linkage 72 by means of rollers or wheels (68), into the sealing position over the cooling shaft 41 (figure 3). The cooling shaft shutter 8 is emplaced, raised, and moved by a manipulator 14 that is arranged on the platform 42. In the sealing position of the cooling shaft shutter 8 a sealing ring 55 that is attached to it is lowered into the water trough 10 (figure 3).
Figure 5 shows the water trough 10 that is filled with water 13, into which the sealing ring 11 is lowered. A connection with the hopper 1 is formed by a flexible sealing element 12 that rests against an annular collar 52 of the hopper 1.
Figure 6 shows the drive unit 16 that is used to raise and lower the distributor cone 5 and the sealing ring 11 (in detail) which, in the example shown, is formed as a linear drive system.
Figures 7 to 10 show another configuration of the lower section 18 of the hopper that can be raised and lowered; this is associated with the stationary hopper 1 that is installed on the supporting structure 7, and simultaneously helps perform the function of a sealing ring 111. The distributor cone 5 is mounted rigidly through the pipe section 40 and the transverse support 39 is attached to the lower section 18 of the hopper. In the raised position (figure 9) there is sufficient space to manipulate the cooling shaft shutter 8 and move it from its rest position (figure 10) to a position above the shaft head 51 of the cooling shaft 41, and there lower it into its sealing position.
The drive unit 19 for the lower section 18 of the hopper that can be raised and lowered is configured, in this example, as a double thrust piston system in which the pistons 71 are attached to a cross-piece 17 to which the lower section 18 of the hopper is secured. The drive unit 19 is supported against backing supports 70 (figure 8).
Figure 11 shows details of a water trough 10; the sealing ring 111 that is attached rigidly to the lower section 18 of the hopper is lowered into the water 13 that fills this when it is in the sealing position.
~l~Q~la Figures 12 to 15 show a configuration of the coke-charging system that differs from the object shown in figures 7 to l0 by an arrangement of the suction line 8 in the area in which the stationary hopper 1 overlaps the lower sectian 18 of the hopper, which cause design adaptations to the stationary hopper 1 and on the lower section 18 of the hopper, which impact its outer shape, as can be seen in detail in figures 12 to 15.
Figures 16 to 18 show a configuration of the coke-charging system with a distributor cone 5 that can be raised and lowered, which is secured to a cross-piece 17 and which is guided so that it can be moved into and out of position in the guide openings 67 of the stationary hopper 1, which can be closed by means of the sealing plates 34 that are connected to the cross-piece 17. The raising and lowering operation is effected by drive units 190 that are attached to the ends of the cross-piece 17 (figure 17).
The stationary hopper 1 has an associated lower section 18 that can be raised and lowered through a short distance. In addition, this coke-charging system has a moveable hopper 202 and a moveable cooling shaft shutter 800. The moveable hopper 202 and the moveable cooling shaft shutter 800 are moved by a common drive system. The drive system is not shown in the drawings.
Figure 16 shows the moveable cooling shaft shutter 800 in the sealing position and the moveable hopper 202 in the resting position. Both the moveable hopper 202 and the moveable cooling shaft shutter 800 support metal sealing rings 31 on both sides, these corresponding to appropriate metal sealing rings 31 that are arranged on the shaft head 51 or in the lower area of the lower section 18 of the hopper which can be raised and lowered.
The metal sealing rings can be either hard plated or be provided with soft seals on their sealing side, and optionally cooling can be provided. Nozzle ring lines 32 are provided in order to keep the mechanical sealing rings 31 clean and these nozzles discharge compressed air. In the resting position, the moveable shutter 202 or the moveable cooling shaft shutter 800, respectively, can be guided in cover plates 35 and supported so as to be sprung.
By using the dry metal-to-metal sealing principle, during the placement process of the moveable hopper 202 for a moveable cooling shaft shutter 800, for all practical purposes, there are no openings to the atmosphere through which dust emissions could escape to the atmosphere in this area.
As can be seen in figure 18, which is a detailed drawing, the lower section 18 of the hopper that can be raised and lowered is, in this example, configured in two parts and comprises a pressure ring 330 and a telescoping ring 333. The pressure ring 330 is fitted underneath with a metal sealing ring 31 and above with a collar 331 that is associated with a drive system 332, in this example a thrust-piston drive, the pistons 335 of which press the pressure ring 330 onto the metal sealing ring 31 of the moveable cooling shaft shutter 800 or of the moveable hopper 202, respectively. The telescoping ring 333 is guided in the pressure ring 330 and incorporates a compensator 334.
As can be seen in figures 19, 20, and 21 by way of an example, the stationary hopper 1 of the coke-charging system can be fitted with a hopper shutter 20 that comprises two shutter plates 64 and 65 which are shown in figure 19 in the open position and in figure 20 in the sealed position. In the perspective drawing shown in figure 1, the shutter plate 64 is secured to a lever linkage 66 that is operated by means of a drive system 21.
Figure 21: the actuating system for the object shown in figures 19 and 20.
Figure 1 shows a stationary hopper 1 that is supported in a supporting structure 7, with which a sealing ring 11 that can be raised and lowered is associated, and which is simultaneously configured as a hopper lower section 18 that can be raised and lowered, and which can be actuated by a drive unit 16. This simultaneously serves to raise and lower a distributor cone 5 that is mounted on a transverse support 39 through a section of pipe 40, as can be seen in figure 2. The supporting structure 7 as well as the drive unit 16 are supported on and secured to a platform 42 that is arranged at the same height as the shaft head 51 on a cooling shaft 41. A water trough 10 is provided on the shaft head 51 of the cooling shaft 41 and a sealing ring 11 extends into this in the sealing position (figure 2). Suction lines 9 are arranged on the stationary hopper 1 (figure 2), to which exhaust fans (not shown herein) are connected; these fans are run when the hot coke is loaded, charge by charge, into the cooling shaft 41, and they are also operated during the change-over periods during which, after the distributor cone 5 and the sealing ring 11 or the lower section 18 of the hopper, respectively, have been raised, a cooling shaft shutter 8 is moved from the resting position (figure 4) by a travelling linkage 72 by means of rollers or wheels (68), into the sealing position over the cooling shaft 41 (figure 3). The cooling shaft shutter 8 is emplaced, raised, and moved by a manipulator 14 that is arranged on the platform 42. In the sealing position of the cooling shaft shutter 8 a sealing ring 55 that is attached to it is lowered into the water trough 10 (figure 3).
Figure 5 shows the water trough 10 that is filled with water 13, into which the sealing ring 11 is lowered. A connection with the hopper 1 is formed by a flexible sealing element 12 that rests against an annular collar 52 of the hopper 1.
Figure 6 shows the drive unit 16 that is used to raise and lower the distributor cone 5 and the sealing ring 11 (in detail) which, in the example shown, is formed as a linear drive system.
Figures 7 to 10 show another configuration of the lower section 18 of the hopper that can be raised and lowered; this is associated with the stationary hopper 1 that is installed on the supporting structure 7, and simultaneously helps perform the function of a sealing ring 111. The distributor cone 5 is mounted rigidly through the pipe section 40 and the transverse support 39 is attached to the lower section 18 of the hopper. In the raised position (figure 9) there is sufficient space to manipulate the cooling shaft shutter 8 and move it from its rest position (figure 10) to a position above the shaft head 51 of the cooling shaft 41, and there lower it into its sealing position.
The drive unit 19 for the lower section 18 of the hopper that can be raised and lowered is configured, in this example, as a double thrust piston system in which the pistons 71 are attached to a cross-piece 17 to which the lower section 18 of the hopper is secured. The drive unit 19 is supported against backing supports 70 (figure 8).
Figure 11 shows details of a water trough 10; the sealing ring 111 that is attached rigidly to the lower section 18 of the hopper is lowered into the water 13 that fills this when it is in the sealing position.
~l~Q~la Figures 12 to 15 show a configuration of the coke-charging system that differs from the object shown in figures 7 to l0 by an arrangement of the suction line 8 in the area in which the stationary hopper 1 overlaps the lower sectian 18 of the hopper, which cause design adaptations to the stationary hopper 1 and on the lower section 18 of the hopper, which impact its outer shape, as can be seen in detail in figures 12 to 15.
Figures 16 to 18 show a configuration of the coke-charging system with a distributor cone 5 that can be raised and lowered, which is secured to a cross-piece 17 and which is guided so that it can be moved into and out of position in the guide openings 67 of the stationary hopper 1, which can be closed by means of the sealing plates 34 that are connected to the cross-piece 17. The raising and lowering operation is effected by drive units 190 that are attached to the ends of the cross-piece 17 (figure 17).
The stationary hopper 1 has an associated lower section 18 that can be raised and lowered through a short distance. In addition, this coke-charging system has a moveable hopper 202 and a moveable cooling shaft shutter 800. The moveable hopper 202 and the moveable cooling shaft shutter 800 are moved by a common drive system. The drive system is not shown in the drawings.
Figure 16 shows the moveable cooling shaft shutter 800 in the sealing position and the moveable hopper 202 in the resting position. Both the moveable hopper 202 and the moveable cooling shaft shutter 800 support metal sealing rings 31 on both sides, these corresponding to appropriate metal sealing rings 31 that are arranged on the shaft head 51 or in the lower area of the lower section 18 of the hopper which can be raised and lowered.
The metal sealing rings can be either hard plated or be provided with soft seals on their sealing side, and optionally cooling can be provided. Nozzle ring lines 32 are provided in order to keep the mechanical sealing rings 31 clean and these nozzles discharge compressed air. In the resting position, the moveable shutter 202 or the moveable cooling shaft shutter 800, respectively, can be guided in cover plates 35 and supported so as to be sprung.
By using the dry metal-to-metal sealing principle, during the placement process of the moveable hopper 202 for a moveable cooling shaft shutter 800, for all practical purposes, there are no openings to the atmosphere through which dust emissions could escape to the atmosphere in this area.
As can be seen in figure 18, which is a detailed drawing, the lower section 18 of the hopper that can be raised and lowered is, in this example, configured in two parts and comprises a pressure ring 330 and a telescoping ring 333. The pressure ring 330 is fitted underneath with a metal sealing ring 31 and above with a collar 331 that is associated with a drive system 332, in this example a thrust-piston drive, the pistons 335 of which press the pressure ring 330 onto the metal sealing ring 31 of the moveable cooling shaft shutter 800 or of the moveable hopper 202, respectively. The telescoping ring 333 is guided in the pressure ring 330 and incorporates a compensator 334.
As can be seen in figures 19, 20, and 21 by way of an example, the stationary hopper 1 of the coke-charging system can be fitted with a hopper shutter 20 that comprises two shutter plates 64 and 65 which are shown in figure 19 in the open position and in figure 20 in the sealed position. In the perspective drawing shown in figure 1, the shutter plate 64 is secured to a lever linkage 66 that is operated by means of a drive system 21.
