Description

Technical Field

[0001] The invention relates to the technical field of steel slag processing equipment, and in particular to a hot slag splashing protection device and a hot slag splashing pool. Background Art

[0002] In metallurgical engineering, concrete slag pools are used to treat high-temperature steel slag. The temperature of hot steel slag is as high as about 400℃-500℃. A large amount of water vapor will be quickly generated during the slag treatment. These rapidly generated water vapor will produce a large thermal expansion force, which will squeeze the wall of the concrete slag pool. The wall of the concrete slag pool is prone to cracking under the action of thermal expansion force, which greatly shortens the service life of the concrete slag pool. And when the concrete slag pool is severely cracked, the wall of the concrete slag pool may collapse under the impact of thermal expansion force, which will cause great safety hazards.

[0003] In order to reduce the impact of thermal expansion force on the concrete slag pool, a protective plate is generally installed directly on the inner wall of the concrete slag pool. The protective plate is mostly made of cast iron plate. During installation, multiple cast iron plates are welded together to cover the inner wall of the concrete slag pool. The protective plate prevents the thermal expansion force from acting directly on the concrete slag pool, which plays a certain protective role.

[0004] However, since the protective plate is directly mounted on the inner wall of the concrete slag pool, the impact of the thermal expansion force on the protective plate can still be transmitted to the concrete slag pool, so that the pool body of the concrete slag pool may still crack. When hot steel slag is poured on the protective plate, the protective plates may be heated unevenly, which will affect the concrete slag pool, causing the concrete slag pool to be affected by high temperature and reduce the stress-bearing performance of the concrete, resulting in a shortened service life of the concrete slag pool. The thermal expansion force will also cause a strong impact on the protective plate. When the protective plate is subjected to long-term direct impact, it may fail and break or fall from the concrete slag pool. Therefore, the protective plate needs to be frequently repaired and replaced. Frequent inspection of the protective plate will seriously affect the normal use of the concrete slag pool. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a hot slag protection device and a hot slag pool.

The hot slag pool protection device has good protection performance for the hot slag pool, and can reduce the damage to the hot slag pool caused by heat and impact; the hot slag pool can reduce the influence of heat and expansion shock on the pool body by using the aforementioned hot slag protection device, thereby improving the service life of the hot slag pool.

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] During the hot splash slag process, the hot splash slag pool is impacted by the steam expansion force, making the pool body of the hot splash slag pool prone to cracking under the impact. Moreover, the pool body of the hot splash slag pool is generally made of concrete. If the hot steel slag is directly poured into the hot splash slag pool, the heat of the hot steel slag will be transferred to the pool body of the hot splash slag pool, causing the mechanical properties of the pool body of the hot splash slag pool to decline due to the high temperature, and then the superposition of expansion impact will greatly reduce the service life of the hot splash slag pool. This application mainly solves the protection problem of the hot splash slag pool through a hot splash slag protection device.

[0046] Please refer to Figures 1 to 7 For this application, a hot splash slag protection device is provided. The hot splash slag protection device includes a slag splashing tank 2 arranged in the hot splash slag pool 1. The slag splashing tank 2 includes a protection bottom plate 21 and a protection side plate 22 connected to the protection bottom plate 21. The protection bottom plate 21 is arranged at the bottom of the hot splash slag pool 1, and the protection side plate 22 is arranged along the side wall of the hot splash slag pool 1. A first heat insulation gap 23 is formed by arranging the protection bottom plate 21 at an interval from the bottom of the pool, and a second heat insulation gap 24 is formed by arranging the protection side plate 22 at an interval from the side wall. A buffer structure 3 is arranged between the protection side plate 22 and the side wall.

[0047] Overall, when the hot splash slag protection device of this application is in use, the hot steel slag is directly poured into the slag splashing tank 2, and then the hot splash slag operation is carried out in the slag splashing tank 2. A first heat insulation gap 23 can be formed between the protection bottom plate 21 of the slag splashing tank 2 and the bottom of the hot splash slag pool 1, and a second heat insulation gap 24 can be formed between the protection side plate 22 of the slag splashing tank 2 and the side wall of the hot splash slag pool 1. Due to the first heat insulation gap 23 and the second heat insulation gap 24, the heat of the hot steel slag cannot be directly transferred to the hot splash slag pool 1, thereby reducing the decline of the mechanical properties of the hot splash slag pool 1 caused by high temperature. Specifically, the temperature of the hot steel slag is about 400°C - 500°C, and under the action of the first heat insulation gap 23 and the second heat insulation gap 24, the temperature received by the inner wall of the hot splash slag pool 1 is reduced to below 250°C, forming an effective heat insulation protection for the hot splash slag pool 1. During the slag splashing process, when the cooling water encounters the hot steel slag, strong steam expansion impact will be generated. If the expansion impact directly acts on the hot splash slag pool 1, it will cause the side wall of the hot splash slag pool 1 to crack. Generally, the hot splash slag pool 1 has three side walls, and there is a slag inlet on one side. The hot splash slag protection device of this application is provided with a buffer structure 3 between the protection side plate 22 and the side wall of the hot splash slag pool 1, and the buffer structure 3 is used to buffer and absorb the expansion impact, effectively protecting the side wall of the hot splash slag pool 1 and reducing the generation of side wall cracks.

[0048] Specifically, please refer to Figures 1 to 7 This hot splash slag protection device may include: a hot splash slag pool 1; a slag splashing tank 2; a buffer structure 3; an anti-tipping mechanism 4; a slag retaining plate 5; a support structure 6.

[0049] In this embodiment, the buffer structure 3 includes a buffer member 31 disposed in the second heat insulation gap 24. One end of the buffer member 31 is provided with a first connection portion 311, and the other end of the buffer member 31 is provided with a second connection portion 312. The first connection portion 311 is in contact with the side wall, and the second connection portion 312 is in contact with the protective side plate 22. By providing the buffer member 31 in the second heat insulation gap 24, after the protective side plate 22 is subjected to an expansion impact, the buffer effect of the buffer member 31 can greatly reduce the expansion impact, so that the expansion impact cannot cause a strong impact on the side wall of the hot slag splashing pool 1, preventing the side wall of the hot slag splashing pool 1 from generating cracks under the action of impact shear force.

[0050] Specifically, the buffer member 31 can be a plate body with a certain elasticity. The buffer member 31 uses the self-elastic deformation of the plate body to buffer the expansion impact. After buffering, the plate body is reset by its own restoring force, so that the buffer member 31 can operate normally for a long time. The user can reasonably select the material of the plate body according to needs, which is not limited here.

[0051] When both ends of the plate body are fixed, it may cause irreversible deformation of the plate body due to excessive expansion impact force. To avoid this phenomenon, in this embodiment, at least one first sliding groove 313 is provided on the second connection portion 312, and a first sliding block 314 corresponding to the first sliding groove 313 is provided on the protective side plate 22. The first sliding block 314 is movably clamped in the corresponding first sliding groove 313. Specifically, the first sliding block 314 can be a bolt structure. One end of the bolt is fixedly connected to the protective side plate 22, and the other end of the bolt passes through the first sliding groove 313 and is connected with a limit nut. Through the cooperation of the first sliding groove 313 and the first sliding block 314, one end of the plate body can obtain a certain degree of freedom. When subjected to an expansion impact, the plate body can displace along the first sliding groove 313 and the protective side plate 22, thereby preventing the deformation stress from being concentrated on the plate body entirely, playing a protective role for the plate body and increasing the service life of the plate body.

[0052] Among them, the plate body disposed between the side wall of the hot slag splashing pool 1 and the protective side plate 22 can be an integral plate body or a segmented plate body composed of multiple parts. During use, a group of plate bodies can be provided between the side wall of the hot slag splashing pool 1 and the protective side plate 22 as the buffer member 31, or multiple groups of plate bodies can be arranged in parallel between the side wall of the hot slag splashing pool 1 and the protective side plate 22 along the height direction to strengthen the buffer effect. The user can adjust the form and quantity of the buffer member 31 provided according to needs, which is not limited here.

[0053] During the use of the buffer member 31, a part of the expansion impact of the buffer member 31 is also transmitted to the side wall of the hot slag splashing pool 1. In order to reduce the influence of this expansion impact on the side wall, the strength of the side wall of the hot slag splashing pool 1 at the junction with the first connecting portion 311 can be enhanced. Specifically, a support plate 315 is embedded in the side wall, and the first connecting portion 311 is fixedly connected to the support plate 315. The support plate 315 can evenly distribute the expansion impact transmitted by the first connecting portion 311 to the side wall of the hot slag splashing pool 1, avoiding the phenomenon of impact concentration, playing a role of uniform distribution, and providing good protection for the side wall of the hot slag splashing pool 1.

[0054] Of course, as another replaceable implementation manner of the buffer member 31, the user can adjust the selected type of the buffer member 31 according to needs, which is not limited here. For example, buffer springs can be used instead of the plate body. During use, a plurality of buffer springs are arranged between the side wall of the hot slag splashing pool 1 and the protective side plate 22 to achieve the same buffer effect as the plate body. Or, rubber cushion blocks can be used to replace the plate body, and the rubber cushion blocks are arranged between the side wall of the hot slag splashing pool 1 and the protective side plate 22 to play a buffer role.

[0055] Since the protective side plate 22 needs to withstand the extrusion and high temperature of the hot steel slag, it is mostly made of steel. Selecting steel can make the protective side plate 22 have a certain recoverability and be able to reset after deformation, but this also makes the protective side plate 22 have a relatively large weight. When the protective side plate 22 is affected by high temperature and expansion impact for a long time, the connection between the protective side plate 22 and the protective bottom plate 21 may be disconnected, resulting in the phenomenon of the protective side plate 22 tipping over. In order to prevent the protective side plate 22 from tipping over in the hot slag splashing pool 1, in this embodiment, an anti-tipping mechanism 4 is provided between the protective side plate 22 and the side wall.

[0056] Specifically, the anti-tipping mechanism 4 includes at least one first limiting member 41. The first limiting member 41 is connected to the protective side plate 22. A protective sleeve 413 is provided on the side wall. The first limiting member 41 is movably inserted into the protective sleeve 413. The first limiting member 41 is provided with a first limiting portion 411 and a second limiting portion 412 at intervals. The first limiting portion 411 and the second limiting portion 412 are respectively arranged on both sides of the side wall. Through the first limiting portion 411 and the second limiting portion 412, the first limiting member 41 can be kept on the side wall of the hot slag splashing pool 1, and then the protective side plate 22 can be pulled by the first limiting member 41 to prevent the protective side plate 22 from tipping over. And through the protective sleeve 413, it can prevent the first limiting member 41 from directly rubbing the side wall of the hot slag splashing pool 1, playing a protective role for the hot slag splashing pool 1. Among them, there is a certain movement gap between the first limiting member 41 and the protective sleeve 413, so that the first limiting member 41 will not be stuck by the protective sleeve 413 during the movement process.

[0057] Furthermore, in order to prevent the protective side plate 22 from being deformed too much by the expansion impact and directly hitting the side wall of the hot slag pouring pool 1, in this embodiment, at least one second limiting member 42 is provided below the first limiting member 41. The second limiting member 42 is in contact with the protective side plate 22. A limiting sleeve 422 corresponding to the second limiting member 42 is provided on the side wall. The limiting sleeve 422 includes a first tube end disposed in the side wall and a second tube end facing the second limiting member 42. A sealing plate 423 is provided at the first tube end. The second limiting member 42 is movably inserted into the limiting sleeve 422, and a third limiting portion 421 cooperating with the second tube end is provided on the second limiting member 42. By forming a blocking limit between the third limiting member and the limiting sleeve 422, it is possible to prevent the protective side plate 22 from being deformed too much and hitting the side wall of the hot slag pouring pool 1. Of course, a blocking limit can also be formed between the sealing plate 423 and the second limiting member 42. Alternatively, by providing a small amount of movement allowance in the limiting sleeve 422, when the second limiting member 42 moves in the limiting sleeve 422, when the second limiting member 42 moves with the protective side plate 22 to a certain extent, it will be blocked by the limiting sleeve 422 to form a blocking limit. The user can adjust the structure of the blocking limit as needed, which is not limited here.

[0058] In order to enable the protective side plate 22 to obtain better anti-tipping ability. In this embodiment, two of the first limiting members 41 are provided on each side wall. The two first limiting members 41 are spaced apart at the same height on the side wall. One second limiting member 42 is correspondingly provided below each of the first limiting members 41. The two second limiting members 42 are provided at the same height on the side wall. Through the cooperative action of the two first limiting members 41, the connection between the protective side plate 22 and the side wall can be further strengthened, and the protective side plate 22 can be prevented from tipping over. At the same time, the two first limiting members 41 also play a redundant insurance role with each other, avoiding the failure of the anti-tipping mechanism 4.

[0059] When pouring hot steel slag, the hot steel slag may fall into the second heat insulation gap 24, thereby filling up the second heat insulation gap 24, reducing the heat insulation effect, and causing the buffer member 31 to fail. To prevent the hot steel slag from falling into the second heat insulation gap 24, in this embodiment, the anti-tipping mechanism 4 further includes a slag baffle 5 covering the top opening of the second heat insulation gap 24. One end of the slag baffle 5 is provided with a first mounting portion 51, and the other end of the slag baffle 5 is provided with a second mounting portion 52. The first mounting portion 51 is connected to the protective side plate 22, and the second mounting portion 52 is movably connected to the side wall. Specifically, the first mounting portion 51 can be connected to the top of the protective side plate 22 through an angle steel, and the second mounting portion 52 can be movably lapped on the side wall of the hot slag pond 1. By means of the slag baffle 5, it is prevented that the hot steel slag falls into the second heat insulation gap 24, and the operation stability of the second heat insulation gap 24 and the buffer member 31 is improved.

[0060] Since the protective side plate 22 and the side wall of the hot slag pond 1 will move relative to each other due to expansion impact, in order to avoid the influence of the movement of the protective side plate 22 on the slag blocking effect, in this embodiment, at least one second chute 53 is provided on the second mounting portion 52, and a second slider 54 corresponding to the second chute 53 is provided on the side wall. The second slider 54 is movably clamped in the corresponding second chute 53. Specifically, the second slider 54 can also be a bolt structure. One end of the bolt is fixed in the side wall of the hot slag pond 1, the bolt passes through the second chute 53 and is limited by a limit nut. Through the cooperation of the second chute 53 and the second slider 54, when the protective side plate 22 and the side wall of the hot slag pond 1 move relative to each other, the slag baffle 5 can dynamically cover the top opening of the second heat insulation gap 24, playing a good role in blocking slag.

[0061] Since the hot steel slag has a relatively large weight, to prevent the protective bottom plate 21 from deforming under the influence of the weight of the hot steel slag, in this embodiment, a support structure 6 is provided in the first heat insulation gap 23, and the protective bottom plate 21 is fixedly arranged on the bottom of the pool through the support structure 6. Specifically, the support structure 6 includes a plurality of first support members 61 and a plurality of second support members 62. Each of the first support members 61 is arranged at intervals below the protective bottom plate 21, and the first support member 61 is connected to the protective bottom plate 21 and the bottom of the pool. Each of the second support members 62 is arranged at intervals below the protective side plate 22, and the second support member 62 is connected to the protective side plate 22 and the bottom of the pool. The protective bottom plate 21 is supported by the first support member 61 to prevent the protective bottom plate 21 from deforming under the influence of the weight of the hot steel slag, and the service life of the protective bottom plate 21 is improved. During installation, cushion plates 63 can be arranged between the first support member 61 and the second support member 62 and the bottom of the hot slag pouring pool 1. The cushion plates 63 can be used to disperse the acting force of the support members on the bottom of the pool and improve the service life of the bottom of the pool. And by fixing the second support member 62 to the protective side plate 22, good support for the protective side plate 22 is also achieved, and the anti-tipping property of the protective side plate 22 is improved. During installation, the protective side plate 22 and the protective bottom plate 21 can be welded and fixed to the second support member 62 at the same time. Of course, the user can also adjust the setting quantity and arrangement mode of the first support member 61 and the second support member 62 according to needs, which is not limited here.

[0062] To prevent the protective bottom plate 21 from deforming and further improve the heat insulation performance of the first heat insulation gap 23, in this embodiment, a heat insulation filling layer is provided in the first heat insulation gap 23. Specifically, the heat insulation filling layer can be made of basalt or andesite gravel. Of course, other types of materials can also be filled in the first heat insulation gap 23, and the user can make a reasonable choice according to needs, which is not limited here.

[0063] To prevent the protective side plate 22 from colliding with the side wall of the hot slag pouring pool 1 under the influence of expansion impact, in this embodiment, along the height direction, the second heat insulation gap 24 is gradually increased from bottom to top. Specifically, the side wall of the hot slag pouring pool 1 can be gradually thinned from bottom to top along the height direction, so that the second heat insulation gap 24 is gradually increased from bottom to top. When the protective side plate 22 deforms under the influence of expansion impact, the upper part of the protective side plate 22 has a larger deformation amount, and the gradually increasing second heat insulation gap 24 can give more deformation space to prevent the protective side plate 22 from colliding with the side wall of the hot slag pouring pool 1. And through the gradually increasing second heat insulation gap 24, the heat transferred from the hot steel slag to the hot slag pouring pool 1 can be further reduced.

[0064] When the hot slag splash protection device described in this application is in use, the hot steel slag is poured into the slag splashing tank 2, and the slag splashing operation is completed in the slag splashing tank 2. The first heat insulation gap 23 and the second heat insulation gap 24 are used to prevent the heat of the hot steel slag from being directly transferred to the hot slag splashing pool 1. The cooperation between the protective side plate 22 and the buffer member 31 is used to buffer the steam expansion impact generated during the slag splashing process, preventing the side wall of the hot slag splashing pool 1 from being directly subjected to the expansion impact.

[0065] The beneficial effect of the hot slag protection device described in this application is that it reduces the heat transferred from the hot steel slag to the hot slag splashing pool 1 through the first heat insulation gap 23 and the second heat insulation gap 24, preventing the wall of the hot slag splashing pool 1 from being affected by high temperature and reducing its mechanical properties. And through the buffer member 31, the steam expansion impact generated during the hot slag splashing process can be buffered, preventing strong expansion impact from causing cracks in the hot slag splashing pool 1, playing a good protective role for the hot slag splashing pool 1 and improving the service life of the hot slag splashing pool 1.

[0066] This application also provides a hot slag splashing pool 1, and the hot slag splashing pool 1 includes the hot slag splash protection device described in the foregoing embodiment. By applying the hot slag splash protection device in the hot slag splashing pool 1, the damage to the hot slag splashing pool 1 caused by high temperature and expansion impact can be reduced, and the service life of the hot slag splashing pool 1 is increased.

[0067] After the slag splashing operation on the hot steel slag in the hot slag splashing pool 1, the slag after slag splashing needs to be grabbed out for further treatment. If there is too much residual slag splashing water in the slag, it is not conducive to the subsequent treatment and use of the slag. Therefore, it is necessary to reduce the water content remaining in the slag. Although there is a slag inlet on one side of the slag splashing tank 2, due to the generally large size of the slag splashing tank 2 and the blocking effect of the slag accumulated in the slag splashing tank 2, some slag splashing water may still remain in the slag splashing tank 2.

[0068] In order to drain the slag splashing water in the slag splashing tank 2 to reduce the water content in the slag, in this embodiment, a drain pipe 12 can be penetrated through the side wall of the hot slag splashing pool 1. The inlet of the drain pipe 12 is set at the same height as the bottom of the slag splashing tank 2, and a drainage structure 13 is provided below the outlet of the drain pipe 12. Specifically, the drainage structure 13 can be a drainage trough.

[0069] Among them, the drain pipe 12 can be horizontally passed through the side wall of the hot slag pouring pool 1. During the use of the slag pouring trough 2, the steel slag will impact and wear the protective bottom plate 21 of the slag pouring trough 2, making it easy for holes to appear in the protective bottom plate 21. As a result, the water in the slag pouring trough 2 will enter the heat insulation gap. The inlet of the drain pipe 12 can be connected to the heat insulation gap to discharge the remaining slag pouring water in the heat insulation gap and the slag pouring trough 2. The outlet of the drain pipe 12 is arranged outside the hot slag pouring pool 1 for discharging water. The horizontal setting method facilitates the overflow discharge of the slag pouring water in the hot slag pouring pool 1. By setting the drain pipe 12 at the same height as the bottom of the slag pouring trough 2, the liquid level height of the slag pouring water remaining in the slag pouring trough 2 does not exceed the protective bottom plate 21, greatly reducing the water content in the steel slag. Further, the outlet of the drain pipe 12 can extend out of the side wall of the hot slag pouring pool 1 and be arranged above the drain trough for easy drainage.

[0070] Of course, the user can also reasonably select other drainage structures 13 with the same function, which are not limited here. Through the drain pipe 12, it can be used to discharge the slag pouring water in the hot slag pouring pool 1, reduce the water content in the steel sand after slag pouring, and facilitate the subsequent collection process of the steel slag. Through the drain trough, the slag pouring water discharged from the drain pipe 12 can be collected and the slag pouring water can be led out for separate treatment.

[0071] In order to further enhance the strength of the side wall of the hot slag pouring pool 1 and prevent the side wall of the hot slag pouring pool 1 from collapsing, in this embodiment, a buttress structure is provided on the outer side surface of the side wall of the hot slag pouring pool 1, and the buttress structure includes at least one buttress 11. Specifically, the number and position of the buttresses 11 provided on each side wall can be determined according to needs, which are not limited here. Among them, the buttress 11 can be a frame structure externally connected to the side wall of the hot slag pouring pool 1, or an integral structure with the side wall of the hot slag pouring pool 1. The user can reasonably adjust the structure of the buttress 11 according to needs, which are not limited here. The buttress 11 plays a supporting role in the side wall of the hot slag pouring pool 1, which can strengthen the strength of the side wall of the hot slag pouring pool 1 and prevent the side wall of the hot slag pouring pool 1 from collapsing, reducing the safety risk.
