Description

Technical Field

[0001] The present invention relates to the field of calcium carbide cooling, and in particular to a three-dimensional storage device for utilizing calcium carbide waste heat and the application of the device in power generation. Background Art

[0002] During the production process of calcium carbide, it reaches a high temperature of 2000℃ when it is refined from the calcium carbide furnace and needs to be cooled before entering the next process. The existing technology has proposed some special equipment for cooling calcium carbide to speed up the cooling rate of calcium carbide, but these equipment are often difficult to use in large-scale production due to their complex structure and are not suitable for large-scale calcium carbide production environments. Therefore, in the existing technology, large factories produce calcium carbide by laying out an extremely long transport track between the calcium carbide furnace and the next process (dumping device) to allow the calcium carbide to cool naturally during transportation. This means that a single cooling process will take up a lot of space and also brings trouble to the work of the staff. Summary of the Invention

[0007] Each turntable first transmission gear 31 on one of the first guide rods 33 is staggered with the turntable second transmission gear 32 of the corresponding layer. The staggered setting means that when the turntable first transmission gear 31 of the first layer is engaged with the turntable second transmission gear 32 of the corresponding layer, the turntable first transmission gear 31 of the second layer is staggered with the turntable second transmission gear 32 of the corresponding layer by a height p, and the turntable first transmission gear 31 of the mth layer is staggered with the turntable second transmission gear 32 of the corresponding layer by a height m-1p.

[0009] Each roller first transmission gear 41 on a second guide rod 43 is staggered with the corresponding roller second transmission gear 422. The staggered setting means that when the first roller first transmission gear 41 is engaged with the roller second transmission gear 422 of the corresponding layer, the second roller first transmission gear 41 and the roller second transmission gear 422 of the corresponding layer are staggered by a distance q, and the nth roller first transmission gear 41 and the roller second transmission gear 422 of the corresponding layer are staggered by a distance n-1q. The thickness of the first high-thickness gear 35 is ≥n*q, so that the fixed roller drive mechanism 4 can only provide power for one of the n fixed rollers 7 of a layer at the same time.

[0011] A steam boiler 8 is arranged above the bracket 1. The steam boiler 8 includes a boiler drum 81. One end of a group of L-shaped pipes is fixedly connected to each other on both sides of the boiler drum 81. The other end of the L-shaped pipe is fixedly connected to a lower connecting box 83.

Multiple upcomers are arranged in parallel to form a water-cooled wall 84, so that the steam boiler 8 forms a cover structure covering the bracket 1; the lower connecting box 83 is set on the ground or fixedly connected to a support frame 86 set on the ground.

[0012] A method for applying a three-dimensional storage device for utilizing calcium carbide waste heat comprises the following steps:

[0013] S1. Calcium carbide fresh from the calcium carbide furnace is fed into a calcium carbide container. The calcium carbide container is transported via a roller conveyor to the roller conveyor lifting and transfer mechanism 5 at the entrance. The roller conveyor lifting and transfer mechanism 5 controls the second turntable mechanism 20 carried by it to a corresponding height via the third hydraulic cylinder 52. The turntable 22 is rotated by the fourth hydraulic motor 56 so that the roller conveyor structure 6 is aligned with the calcium carbide container to receive it. After receiving, the second turntable mechanism 20 is lifted to the height of the top layer of the support 1 via the third hydraulic cylinder 52, and the turntable 22 is rotated to the appropriate position via the fourth hydraulic motor 56.

[0014] S2. Control the first hydraulic cylinder 36 to extend and retract, so that the second transmission gear 32 of the turntable on the top layer engages with the corresponding first transmission gear 31 of the turntable, and start the first hydraulic motor 37. The turntable 22 on the pedestal 11 is driven to rotate by the first driving gear 371-first high-thickness gear 35-turntable first transmission gear 31-turntable second transmission gear 32-turntable driven gear 21. In this way, the multiple turntable mechanisms 2 on the top layer of the bracket 1 are controlled to rotate through the corresponding turntable driving mechanisms 3 to form a continuous roller conveyor, and the calcium carbide container on the roller conveyor lifting and transferring mechanism 5 is received by the continuous roller conveyor;

[0015] S3. Each fixed roller conveyor 7 can carry multiple calcium carbide containers according to their length. When a fixed roller conveyor 7 on the top layer has a vacant position, the turntable mechanism 2 corresponding to the entrance of the fixed roller conveyor 7 receives the calcium carbide container and controls the turntable 22 to rotate to a suitable position through the turntable drive mechanism 3 so that the fixed roller conveyor 7 can receive the calcium carbide container.

[0016] S4. Control the second hydraulic cylinder 46 to extend and retract, so that the second transmission gear 422 of the fixed roller table 7 corresponding to the calcium carbide container engages with the corresponding first transmission gear 41 of the roller table. Start the second hydraulic motor 47, which drives the rollers on the fixed roller table 7 to rotate via the second driving gear 471, the second high-thickness gear 45, the first transmission gear 41 of the roller table, the second transmission gear 422 of the roller table, the first transmission sprocket 423, and the sprocket of the roller on the fixed roller table 7. In this way, the movement of the calcium carbide container on the fixed roller table 7 is controlled. Whenever a new calcium carbide container is transported, the fixed roller table 7 travels a stroke the length of the calcium carbide container.

[0017] S5. When all the fixed roller conveyors 7 on the top floor have no empty spaces, the turntable mechanism 2 on the outlet side of one of the fixed roller conveyors 7 is rotated to a suitable position by the turntable driving mechanism 3 to receive the first calcium carbide container fed onto the fixed roller conveyor 7. Then, the multiple turntable mechanisms 2 on the outlet side of the top floor are controlled to rotate by the corresponding turntable driving mechanism 3 to form a continuous roller conveyor. The calcium carbide container is received by the roller conveyor lifting and transferring mechanism 5 on the outlet side. Then, the lifting and transferring mechanism 5 is lowered by one level, and the process of S2-S4 is repeated to feed the calcium carbide container onto the fixed roller conveyor 7 on the lower level.

[0018] S6, repeat the process of S5 until there is no vacant space on the bottom of the bracket 1 or the calcium carbide in the calcium carbide container is cooled completely, and the calcium carbide container is received by the roller lifting and transfer mechanism 5 at the exit and transported to the next process via the roller conveyor;

[0019] S7. A steam boiler 8 is set above the bracket 1. The boiler drum 81 of the steam boiler 8 is connected to the water supply system through a water pipe. The water tank in the boiler drum 81 drops the received water to the lower connecting box 83 through the downcomer 82, and distributes it to each riser in the water-cooled wall 84 through the lower connecting box 83. The water is converted into saturated steam by the temperature of the high-temperature calcium carbide in the calcium carbide container, and the saturated steam is merged into the boiler drum 81.

[0020] Compared with the existing technology, the present invention proposes a three-dimensional calcium carbide storage structure. The multi-layer structure makes the entire device not need to occupy a large space. If auxiliary cooling devices (such as nitrogen cooling and exhaust cooling) are required, it can also bring more cost savings compared with the existing technology, and cooperate with the lifting and transfer mechanism to realize the transfer between multi-layer structures.

[0038] As attached Figure 1-2 As shown, the three-dimensional storage equipment for utilizing waste heat of calcium carbide includes a bracket 1 with an m-layer structure, m≥2, at least one fixed roller 7 is provided on each layer of the bracket 1, a pedestal 11 is provided on the side of each layer of the bracket 1, a turntable mechanism 2 is provided on the upper part of the pedestal 11, a roller structure 6 is provided on the upper part of the turntable mechanism 2, and the turntable mechanisms 2 are respectively arranged in groups of two at the front and rear ends of the fixed roller 7, and a lifting and transferring mechanism is provided on one side of the pedestal 11, so that the transported calcium carbide container is lifted to the corresponding layer through the lifting and transferring mechanism, and transferred to the corresponding fixed roller 7 through the turntable mechanism 2.

[0039] Preferably, the fixed rollers 7 are arranged in parallel so that Figure 1 As shown in the figure, one end is used as an outlet to receive the calcium carbide container transported from the calcium carbide furnace, and the other end is used as an outlet to transport the cooled calcium carbide away; the lifting and transfer mechanism can be a crane mechanism or other lifting mechanism in the prior art, and the preferred one is the roller lifting and transfer mechanism 5 proposed later.

[0040] Preferably, since the pedestal 11 is a cantilever, considering the support strength, one corner of the pedestal 11 can be fixedly connected to the structural column to support it on the ground, or a reinforcing rib structure can be provided under the pedestal without affecting transportation.

[0041] The fixed roller 7 and roller structure 6 described in this article can be a common roller structure in the prior art, or can be as shown in the figure, including two tracks, a plurality of roller seats are arranged in an array on the upper part of the track, the roller is arranged between the two tracks and the two ends are rotatably connected to the roller seat, one end of the roller extends out of the roller seat and is fixedly connected to the sprocket, and the roller is operated by connecting all the sprockets in series through a chain and a driving wheel that provides power. This is a mature existing technology and will not be described in detail.

[0042] As attached Figure 3-4As shown, the turntable mechanism 2 includes a turntable driven gear 21 rotatably connected to the upper part of the pedestal 11 through a rotating shaft, the upper part of the turntable driven gear 21 is fixedly connected to the turntable 22, the upper part of the turntable 22 is fixedly connected to the fixed frame 221, the upper part of the fixed frame 221 is provided with a roller structure 6, and the side of the fixed frame 221 is fixedly connected to a third hydraulic motor 23 for providing power to the roller structure 6.

[0043] The fixed frame 221 can be a plate, a block, or a frame, and is required not to restrict the rotation of the turntable mechanism 2, and to provide space for installing the third hydraulic motor 23; the output shaft of the third hydraulic motor 23 is fixedly connected to the sprocket, which provides power to the roller structure 6 of the turntable mechanism 2 through a chain series; further, a plurality of pulley assemblies 24 are arranged between the turntable 22 and the pedestal 11, and the pulley assembly 24 includes a pulley seat fixed on the pedestal 11 and a pulley hinged to the pulley seat, and the pulley contacts the turntable 22 from the side, so that the pulley assembly 24 provides auxiliary support to the turntable mechanism 2, thereby reducing the pressure on the rotating shaft connected to the turntable driven gear 21.

[0044] As attached Figure 5-6 As shown, a turntable drive mechanism 3 is provided on one side of the pedestal 11, and the turntable drive mechanism 3 includes a first hydraulic motor 37, the output shaft of the first hydraulic motor 37 is fixedly connected to the first driving gear 371, the first driving gear 371 meshes with the first high-thickness gear 35, one end of the first high-thickness gear 35 is connected to the piston rod of the first hydraulic cylinder 36, and the other end of the first high-thickness gear 35 is fixedly connected to one end of the first guide rod 33. One side of the pedestal 11 is fixedly connected to the first guide seat 34, the first guide rod 33 passes through the first guide seat 34 and is rotatably connected to the first guide seat 34, and the first guide rod 33 is fixedly connected to the turntable first transmission gear 31 corresponding to each layer of the turntable mechanism 2; the upper part of the pedestal 11 is rotatably connected to the turntable second transmission gear 32 through the rotating shaft, and the turntable second transmission gear 32 meshes with the turntable driven gear 21. When the turntable first transmission gear 31 reaches a specific height through the lifting and lowering of the first guide rod 33, it meshes with the turntable second transmission gear 32 of the corresponding layer. In actual design, the second transmission gear 32 should partially extend out of the pedestal 11 to facilitate cooperation with the turntable first transmission gear 31.

[0045] In detail, the first hydraulic motor 37, the first driving gear 371, the first high-thickness gear 35, and the first hydraulic cylinder 36 should be located below the ground where the bracket 1 is located; the motor base of the first hydraulic motor 37 should be fixed to the ground or wall of the space structure where it is located through a structural plate; since the first high-thickness gear 35 will rotate, the connection method between the piston rod of the first hydraulic cylinder 36 and the first high-thickness gear 35 can include but is not limited to: 1. Rotational connection, such as a ball joint, or the first high-thickness gear 35 is fixedly connected to a structural block, a T-shaped circular groove is set in the structural block, and the piston of the first hydraulic cylinder 36 The upper part of the rod is fixedly connected to a T-key that cooperates with the T-slot, and the cylinder seat of the first hydraulic cylinder 36 is fixedly connected to the ground, so that the first hydraulic cylinder 36 can perform normal push and pull operations on the first high-thickness gear 35 and will not rotate with the first high-thickness gear 35; 2. Fixed connection, the first hydraulic cylinder 36 uses a hydraulic cylinder with a freely rotatable piston rod in the existing technology, and the cylinder seat of the first hydraulic cylinder 36 is fixedly connected to the ground; 3. Fixed connection, the cylinder seat of the first hydraulic cylinder 36 is rotatably connected to the ground by being fixed on a small turntable structure, so that the first hydraulic cylinder 36 can rotate with the first high-thickness gear 35.

[0046] Each turntable first transmission gear 31 on a first guide rod 33 is staggered with the turntable second transmission gear 32 of the corresponding layer. The staggered setting means that when the turntable first transmission gear 31 of the first layer is engaged with the turntable second transmission gear 32 of the corresponding layer, the turntable first transmission gear 31 of the second layer is staggered with the turntable second transmission gear 32 of the corresponding layer by a height p, and the turntable first transmission gear 31 of the mth layer is staggered with the turntable second transmission gear 32 of the corresponding layer by a height of (m-1)p. The thickness of the first high-thickness gear 35 is ≥m*p, so that the turntable drive mechanism 3 can only control the rotation of the turntable mechanism 2 of one layer at a time. The optimal staggered height is staggered in the same direction (staggered downward as shown in the figure) to reduce the difficulty of control.

[0047] As attached Figure 7-9As shown, each layer of the bracket 1 is provided with n fixed rollers 7 in parallel, and a fixed roller drive mechanism 4 is provided at the lower part of each layer of the bracket 1. The fixed roller drive mechanism 4 includes a second hydraulic motor 47, and the output shaft of the second hydraulic motor 47 is fixedly connected to the second driving gear 471. The second driving gear 471 engages with the second high-thickness gear 45. One end of the second high-thickness gear 45 is connected to the piston rod of the second hydraulic cylinder 46, and the other end of the second high-thickness gear 45 is fixedly connected to one end of the second guide rod 43. The lower part of the bracket 1 layer structure is fixedly connected to the second guide seat 44, and the second guide rod 43 passes through the second guide seat 44 and is connected to the second guide seat 44. The two guide seats 44 are rotatably connected, and the second guide rod 43 is fixedly connected to the first roller transmission gear 41 corresponding to each fixed roller 7; the lower part of the bracket 1 layer structure is fixedly connected to the bearing seat 42 corresponding to the fixed roller 7, and the bearing seat 42 is rotatably connected to the rotating shaft 421, and the rotating shaft 421 is respectively fixedly connected to the second roller transmission gear 422 and the first transmission sprocket 423. When the first roller transmission gear 41 moves horizontally through the second guide rod 43 to a specific position, it engages with the corresponding second roller transmission gear 422; the first transmission sprocket 423 provides power to the fixed roller 7 above through the chain.

[0048] In detail, the motor base of the second hydraulic motor 47 is fixedly connected to the bracket, and the cylinder base of the second hydraulic cylinder 46 is connected to the first fixing plate 48. The first fixing plate 48 can be as shown in FIG. Figure 2 The first layer is fixed on the ground, or Figure 2 The second and third layers are fixedly connected to the bracket 1. Since the second high-thickness gear 45 will rotate, the connection method between the piston rod of the first hydraulic cylinder 36 and the first high-thickness gear 35 should refer to the connection relationship between the above-mentioned first hydraulic cylinder 36, the first high-thickness gear 35 and the ground.

[0049] Each roller first transmission gear 41 on a second guide rod 43 is staggered with the corresponding roller second transmission gear 422. The staggered setting means that when the first roller first transmission gear 41 is engaged with the roller second transmission gear 422 of the corresponding layer, the second roller first transmission gear 41 and the roller second transmission gear 422 of the corresponding layer are staggered by a distance q, and the nth roller first transmission gear 41 and the roller second transmission gear 422 of the corresponding layer are staggered by a distance (n-1) q. The thickness of the first high-thickness gear 35 is ≥n*q, so that the fixed roller drive mechanism 4 can only provide power to one of the n fixed rollers 7 of a layer at the same time. The optimal staggered distance is staggered in the same direction (such as Figure 9 to one side as shown in the figure), reducing the difficulty of control.

[0050] As attached Figure 10-11As shown, the lifting and transferring mechanism is a roller lifting and transferring mechanism 5, which includes a base 51, the upper part of the base 51 is fixedly connected to the base of the third hydraulic cylinder 52, the output end of the third hydraulic cylinder 52 is fixedly connected to the turntable seat 54, at least two groups of third guide rods 53 are arranged between the turntable seat 54 and the base 51, a second turntable mechanism 20 is arranged on the upper part of the turntable seat 54, and a roller structure 6 is arranged on the upper part of the second turntable mechanism 20, the second turntable mechanism 20 includes a turntable driven gear 21 rotatably connected to the upper part of the turntable seat 54, and the turntable is rotated from The upper part of the driven gear 21 is fixedly connected to the turntable 22, and the upper part of the turntable 22 is fixedly connected to the fixed frame 221. The roller structure 6 is set on the upper part of the fixed frame 221. The side of the fixed frame 221 is fixedly connected to the third hydraulic motor 23 for providing power to the roller structure 6. The side of the turntable seat 54 is fixedly connected to the second fixed plate 55, and the second fixed plate 55 is fixedly connected to the fourth hydraulic motor 56. The output shaft of the fourth hydraulic motor 56 passes through the turntable seat 54 upward and is fixedly connected to the fourth driving gear 561. The fourth driving gear 561 engages with the turntable driven gear 21.

[0051] The third hydraulic cylinder 52 can be a single-stage hydraulic cylinder, which requires m=2, that is, the bracket 1 has only two layers, or the multi-layer turntable mechanism 2 is within the stroke range of the single-stage hydraulic cylinder.

[0052] The third hydraulic cylinder 52 may also be a multi-stage hydraulic cylinder as shown in the figure, so as to address the problem that the stroke of a single-stage hydraulic cylinder is difficult to meet the height of multiple-layer supports.

[0053] The third guide rod 53 can be a single rod body, and the height of the rod body is higher than the top height of the third hydraulic cylinder 52 at the maximum stroke. One end of the rod body is fixedly connected to the base 51, and the other end passes through the turntable seat 54 and is slidably connected to the turntable seat 54 with a small gap fit. This structure belongs to the common lifting platform guide rod structure in mechanical design and is no longer shown in the picture.

[0054] Preferably, as attached Figure 12 As shown in .1-12.2, the third guide rod 53 is composed of a plurality of solid or hollow rod bodies that are socketed with each other (the innermost rod body can be solid, and the other rod bodies are hollow structures for socketing), and a locking structure is set between the rod bodies. The locking structure includes a groove body set at the bottom of the rod body, one end of the compression spring 531 is fixedly connected in the groove body, and the other end of the compression spring 531 is fixedly connected to the locking slider 532. A locking hole 533 that cooperates with the locking slider 532 is set at the top of the rod body, and an unlocking inclined surface is set on the locking slider 532, so that after the locking slider 532 is inserted into the locking hole 533, the upward displacement of the rod body is limited. When it moves downward, the locking slider 532 automatically slides into the groove body through the unlocking inclined surface.

[0055] The roller lifting and transfer mechanism 5 can not only be used in the three-dimensional storage device of the present application, but can also be used separately for transfer work between two or more rollers with different heights and directions.

[0056] like Figure 1 、 13 As shown in Figure 14, a steam boiler 8 is arranged above the bracket 1. The steam boiler 8 includes a boiler drum 81. One end of a group of L-shaped pipes are fixedly connected on both sides of the boiler drum 81. The other end of the L-shaped pipe is fixedly connected to a lower connecting box 83. The L-shaped pipe includes a downcomer 82 and an upcomer. Multiple upcomers are arranged in parallel to form a water-cooled wall 84. The lower connecting box 83 is set on the ground or fixedly connected to a support frame 86 set on the ground.

[0057] The top of the steam boiler 8 is fixedly connected to a hanging ear 85, which can be used for hoisting to increase support stability.

[0058] The steam boiler 8 is connected to an external water supply system through a water pipe. A water tank connected to the water pipe is provided inside the steam boiler 8. The water tank is connected to the downcomer 82. This belongs to the existing technology and will not be described in detail.

[0059] The steam boiler 8 and the three-dimensional storage mechanism form a boiler structure. The steam generated can be output to an external steam generator for power generation. On the one hand, it cools the calcium carbide, and on the other hand, it collects waste heat to save energy.

[0060] Preferably, an insulating wall is provided on the outside of the steam boiler 8 so that the residual heat of the calcium carbide is fully retained in the "boiler structure", which is closer to the boiler structure in the prior art.

[0061] A method for applying a three-dimensional storage device for utilizing calcium carbide waste heat comprises the following steps:

[0062] S1. Calcium carbide fresh from the calcium carbide furnace is fed into a calcium carbide container. The calcium carbide container is transported via a roller conveyor to the roller conveyor lifting and transfer mechanism 5 at the entrance. The roller conveyor lifting and transfer mechanism 5 controls the second turntable mechanism 20 carried by it to a corresponding height via the third hydraulic cylinder 52. The turntable 22 is rotated by the fourth hydraulic motor 56 so that the roller conveyor structure 6 is aligned with the calcium carbide container to receive it. After receiving, the second turntable mechanism 20 is lifted to the height of the top layer of the support 1 via the third hydraulic cylinder 52, and the turntable 22 is rotated to the appropriate position via the fourth hydraulic motor 56.

[0063] S2. Control the first hydraulic cylinder 36 to extend and retract, so that the second transmission gear 32 of the turntable on the top layer engages with the corresponding first transmission gear 31 of the turntable, and start the first hydraulic motor 37. The turntable 22 on the pedestal 11 is driven to rotate by the first driving gear 371-first high-thickness gear 35-turntable first transmission gear 31-turntable second transmission gear 32-turntable driven gear 21. In this way, the multiple turntable mechanisms 2 on the top layer of the bracket 1 are controlled to rotate through the corresponding turntable driving mechanisms 3 to form a continuous roller conveyor, and the calcium carbide container on the roller conveyor lifting and transferring mechanism 5 is received by the continuous roller conveyor;

[0064] S3. Each fixed roller conveyor 7 can carry multiple calcium carbide containers according to their length. When a fixed roller conveyor 7 on the top layer has a vacant position, the turntable mechanism 2 corresponding to the entrance of the fixed roller conveyor 7 receives the calcium carbide container and controls the turntable 22 to rotate to a suitable position through the turntable drive mechanism 3 so that the fixed roller conveyor 7 can receive the calcium carbide container.

[0065] S4. Control the second hydraulic cylinder 46 to extend and retract, so that the second transmission gear 422 of the fixed roller table 7 corresponding to the calcium carbide container engages with the corresponding first transmission gear 41 of the roller table. Start the second hydraulic motor 47, which drives the rollers on the fixed roller table 7 to rotate via the second driving gear 471, the second high-thickness gear 45, the first transmission gear 41 of the roller table, the second transmission gear 422 of the roller table, the first transmission sprocket 423, and the sprocket of the roller on the fixed roller table 7. In this way, the movement of the calcium carbide container on the fixed roller table 7 is controlled. Whenever a new calcium carbide container is transported, the fixed roller table 7 travels a stroke the length of the calcium carbide container.

[0066] S5. When all the fixed roller conveyors 7 on the top floor have no empty spaces, the turntable mechanism 2 on the outlet side of one of the fixed roller conveyors 7 is rotated to a suitable position by the turntable driving mechanism 3 to receive the first calcium carbide container fed onto the fixed roller conveyor 7. Then, the multiple turntable mechanisms 2 on the outlet side of the top floor are controlled to rotate by the corresponding turntable driving mechanism 3 to form a continuous roller conveyor. The calcium carbide container is received by the roller conveyor lifting and transferring mechanism 5 on the outlet side. Then, the lifting and transferring mechanism 5 is lowered by one level, and the process of S2-S4 is repeated to feed the calcium carbide container onto the fixed roller conveyor 7 on the lower level.

[0067] S6, repeat the process of S5 until there is no vacant space on the bottom of the bracket 1 or the calcium carbide in the calcium carbide container is cooled completely, and the calcium carbide container is received by the roller lifting and transfer mechanism 5 at the exit and transported to the next process via the roller conveyor;

[0068] S7, the boiler drum 81 of the steam boiler 8 is connected to the water supply system through a water pipe. The water tank in the boiler drum 81 will drop the received water to the lower connecting box 83 through the downcomer 82, and distribute it to the various risers in the water-cooled wall 84 through the lower connecting box 83. The water is converted into saturated steam by the temperature of the high-temperature calcium carbide in the calcium carbide container, and the saturated steam is merged into the boiler drum 81.

[0069] Since the calcium carbide with the highest temperature is always placed on the top layer of the bracket 1, close to the top of the water-cooled wall 84, the temperature exchange between the water-cooled wall 84 and the calcium carbide is facilitated.

[0070] It should be noted that the temperature of the calcium carbide just out of the furnace on the top layer is above 2000℃. The residual heat of the calcium carbide naturally rises and contacts the top of the water-cooled wall 84, and the temperature of the calcium carbide on the next layer will dissipate to the upper and surrounding steel frames. Therefore, the temperature of the calcium carbide is required to be lower than 500℃ when it is transferred to the layer below the top layer, which is the maximum allowable temperature or softening temperature of steel (or determined according to the actual material).

[0071] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
