Description

Technical Field

[0001] This utility model relates to an auxiliary device for steel shot processing, and in particular to a molten steel guiding structure. Background Technology

[0002] Container corner fittings, also known as container corners or lifting corners, are mainly used at the various corners of containers. They are produced using sand casting, which involves pouring molten steel into pre-formed sand molds that meet production requirements. As the temperature of the molten steel decreases, it forms the shape of the sand mold. The broken sand scraps can be recycled and reused, thus enabling the efficient production of container corner fittings.

[0003] Traditional steel transfer involves melting steel blocks into molten steel in an incinerator, then pouring the molten steel into a transfer drum. The transfer drum is then moved by an overhead crane to the casting equipment of a ground crane, where the molten steel is poured onto the ladle. While this achieves the desired transfer of molten steel to the ladle, the transfer process is cumbersome and inherently unsafe. The operation requires manual intervention, posing significant safety risks to workers. Current steel transfer methods minimize the distance between the incinerator and the ladle by employing a flow channel guide. However, with molten steel temperatures exceeding 1000 degrees Celsius and a top-down pouring method, ordinary flow channel structures struggle to support the flow. This leads to leakage from the gaps between the flow channel and the casting point. Molten steel at over 1000 degrees Celsius leaking from the side is extremely difficult to manage and can destabilize the entire flow channel. Utility Model Content

[0004] This invention provides a molten steel guiding structure that can continuously stabilize the impact force during pouring and prevent molten steel from overflowing, thus effectively solving the above-mentioned problems.

[0005] This utility model is implemented as follows:

[0006] A molten steel guiding structure, installed on a combustion platform, includes: a combustion cylinder housed inside the combustion platform; an inclined platform connected to the top of the combustion platform; a lower guiding cavity connected to the lower end of the inclined platform; and a movable ladle connected to the bottom end of the lower guiding cavity. The ladle is mounted on a traveling crane. The structure also includes:

[0007] The lower guide cavity includes a guide steel for connecting the ladle and the tilting platform. The guide steel has a lower chute inside. The lower end of the tilting platform is provided with an inner mounting hopper. One side of the top of the guide steel extends into the inner mounting hopper.

[0008] The edge-enclosing mechanism has a leveling seat at the lower end of the tilting platform, and the edge-enclosing mechanism is located on the outside of the leveling seat and closely attached to the outside of the guide steel.

[0009] As a further improvement, the edging mechanism includes an edging structure disposed on the side of the leveling seat, the air outlet cavity of the edging structure facing the gap between the guide steel and the leveling seat, and a vibration damping kit connected to the outer side of the edging structure, the vibration damping kit extending downward and closely attached to the outer side of the guide steel.

[0010] As a further improvement, the guide steel includes an inclined section that supports the lower chute, an upper horizontal section is provided at the upper end of the inclined section, the upper horizontal section is integrally connected with the inner pull seat, and a lower horizontal section is provided at the lower end of the inclined section.

[0011] As a further improvement, the lower end of the leveling seat is provided with two partition rails, and the upper horizontal section has grooves on both sides. When the guide steel is engaged with the inner mounting bucket, the grooves are engaged with the partition rails.

[0012] As a further improvement, the edging structure includes an edging tube disposed on the partition rail, the edging tube being connected to at least one air pump, and the air outlet cavity being connected to the bottom surface of the partition rail with its edge not extending beyond the partition rail.

[0013] As a further improvement, the vibration damping kit includes a first flushing pipe and a second flushing pipe disposed on the outside of the inner mounting hopper. The first flushing pipe and the second flushing pipe are respectively connected to the liquid inlet end and the liquid outlet end. A connecting pipe is provided at one end of the first flushing pipe and the second flushing pipe facing downward into the guide cavity. A quick-connect coupling is provided on the connecting pipe. The connecting pipe is movably connected to a U-shaped circulation pipe that is tightly attached to the lower end of the guide steel.

[0014] The beneficial effects of this utility model are:

[0015] This invention, through its edge-enclosing mechanism, allows for the installation of an edge-enclosing structure at the lower end of the inclined platform. This edge-enclosing structure forms a ring-shaped structure through which high-pressure gas can be introduced. High-pressure gas can then be injected into the gap between the guide steel and the inclined platform, forcing molten steel that might otherwise overflow back inward. This creates an air curtain that prevents molten steel from flowing out of this location, making it extremely suitable for high-temperature molten steel and avoiding the phenomenon that other contact-type sealing structures are easily melted.

[0016] The entire edging structure needs to fully cover the gap between the guide steel and the tilting platform. Therefore, the edging tube of the edging structure of this utility model is a U-shaped structure, which completely surrounds the three sides of the guide steel except for the feeding side, thereby forming a U-shaped air curtain structure, which tightly presses any molten steel that may overflow into the inner side of the dividing rail.

[0017] During the process of molten steel feeding, a certain force is actually exerted on the entire guide steel, which may cause slight displacement of the guide steel and increase the risk of leakage. Therefore, this utility model also sets a vibration damping kit at the lower end of the tilting platform. The vibration damping kit is divided into two parts, namely two flushing pipes and a U-shaped circulation pipe, so that multiple positions of the guide steel can obtain the effect of water flow unloading. The flow of water is used to deal with the fluctuations caused by the continuous feeding of molten steel, making the entire structure more stable. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Reference Figures 1-6As shown, a molten steel guiding structure is installed on a combustion platform 10. A combustion cylinder 11 is housed inside the combustion platform 10. An inclined platform 20 is connected to the top of the combustion platform 10. A lower guiding cavity 30 is connected to the lower end of the inclined platform 20. The bottom end of the lower guiding cavity 30 is connected to a movable ladle. The ladle is mounted on a trolley. The structure further includes: a guiding steel 31 for connecting the ladle and the inclined platform 20 within the lower guiding cavity 30; a lower chute 32 inside the guiding steel 31; an inner mounting hopper 21 at the lower end of the inclined platform 20; and a rear tensioning mechanism 40 disposed inside the inner mounting hopper 21, comprising a connection on the side of the guiding steel 31 near the inclined platform 20. An inner pull seat 41 is provided with a tensioning seat 42 on the side of the inner pull seat 41 away from the guide steel 31. A tensioning component 43 is connected to the tensioning seat 42 and is located inside the inner mounting bucket 21. When the tilting table 20 unloads material, the tensioning component 43 tightly pulls the tensioning seat 42, so that the guide steel 31 is tightly attached to the bottom of the tilting table 20. A rimming mechanism 50 is provided with a leveling seat 22 at the lower end of the tilting table 20. The rimming mechanism 50 includes a rimming structure 51 located on the side of the leveling seat 22. The air outlet cavity 52 of the rimming structure 51 faces the gap between the guide steel 31 and the leveling seat 22. A vibration damping kit 53 is connected to the outside of the rimming structure 51. The vibration damping kit 53 extends downward and is tightly attached to the outside of the guide steel 31.

[0030] It should be emphasized that there is a passage between the entire guide steel 31 and the pouring ladle and the incineration platform 10. In order not to obstruct the normal factory road when not pouring, the guide steel 31 can be disassembled when not in use. Therefore, the guide steel 31 needs to achieve the effect of being disassembled when it is used in conjunction with other structures.

[0031] Existing technologies employ a top-down pouring method, making it difficult for ordinary flow channels to withstand the flow of molten steel. This causes the molten steel to easily leak from the gap between the flow channel and the pouring point. Therefore, in this embodiment, the lower guide cavity 30 includes a guide steel 31 for connecting the ladle and the inclined platform 20. The guide steel 31 has a lower chute 32 inside. The lower end of the inclined platform 20 is provided with an inner mounting hopper 21. One side of the top of the guide steel 31 extends into the inner mounting hopper 21. Initially, a single block of guide steel 31 is used, and then the lower chute 32 is carved out on the inner side of the guide steel 31 to ensure the smooth flow of molten steel. The flow channels are integrated into a single structure, ensuring stability during flow. Furthermore, the top of the entire guide steel 31 is embedded within the inner mounting hopper 21. The tensioning assembly 43 on the rear tensioning mechanism 40 installed in the inner mounting hopper 21 tightens the tensioning seat 42 located on the inner side of the top of the guide steel 31, thereby minimizing the gap between the entire guide steel 31 and the tilting platform 20. This reduces vibrations caused by pouring molten steel, allowing the molten steel to flow stably during pouring and preventing spillage from the sides. The inner mounting hopper 21 is integrated with the tilting platform 20 and remains stationary.

[0032] The tensioning seat 42 is not actually a structure welded separately to the guide steel 31. If it were a welded structure, it would be easy to disengage under tension. Therefore, the tensioning seat 42 in this embodiment includes an inner groove 421 recessed inward towards the inner pull seat 41. At least two tensioning arms 422 are provided in the inner groove 421. The two tensioning arms 422 are connected to the tensioning assembly 43. The tensioning seat 42 is actually an integral structure with the guide steel 31, except that it is recessed inward towards the inner pull seat 41. Thus, the tensioning arms 422 are actually an integral structure with the guide steel 31, and can be prevented from breaking even when subjected to force.

[0033] During the engagement of the tensioning assembly 43 with the tensioning seat 42, the tensioning is not directly achieved through anchor bolts. Specifically, the tensioning assembly 43 includes a connector 431 that engages with the tensioning arm 422. The connector 431 is connected to a bidirectional buffer 432. A rigid connector 433 is connected to the side of the bidirectional buffer 432 away from the connector 431. The rigid connector 433 extends to the outside of the inner mounting bucket 21. It first establishes an engagement with the tensioning arm 422 through the connector 431, holding the guide steel 31 in place. Then, the rigid connector 433 extends the connector 431 to the position of the inner mounting bucket 21. Furthermore, a bidirectional buffer 432 is provided between the rigid connector 433 and the connector 431 for elastic buffering, thereby avoiding direct rigid connection tensioning and instead distributing the force through multi-segment connections.

[0034] During the engagement of the connector 431 with the tensioning arm 422, since the tensioning arm 422 is distributed in two segments, the connector 431 in this embodiment includes two swing arms 4311 sleeved on the two tensioning arms 422. The ends of the two swing arms 4311 away from the tensioning arm 422 are fixed to a connecting block 4312. The connecting block 4312 is connected to an extension arm 4313. The end of the extension arm 4313 is connected to the bidirectional buffer 432. The connector 431 is also set with two swing arms 4311, so that both ends are fixed, thereby forming a bidirectional force relief effect. By extending the distance through the extension arm 4313, a multi-directional, long-axis force guiding effect is achieved.

[0035] If the connection 431 and the rigid connector 433 are rigidly fitted, the vibration will easily act directly on the entire rod when subjected to shock. Therefore, the bidirectional buffer 432 in this embodiment includes a middle partition 4321 fixed between the extension arm 4313 and the rigid connector 433. A small stiffness spring 4322 is provided on the side of the middle partition 4321 near the connection 431, and a large stiffness spring 4323 is provided on the side of the middle partition 4321 away from the connection 431. The small stiffness spring 4322 is connected to the inner pull seat 41, and the large stiffness spring 4323 is connected to the inner side wall of the inner mounting bucket 21. The bidirectional buffer 432 is set between the connection 431 and the rigid connector 433. Through the cooperation of the small stiffness spring 4322 and the large stiffness spring 4323 at both ends, the vibration generated by the entire mechanism can be adaptively mitigated, thereby extending the service life of other structures.

[0036] When the rigid connector 433 tightens the connector 431 and the bidirectional buffer 432, it needs a point of force to ensure the stability of the entire structure. Therefore, the rigid connector 433 in this embodiment includes a rigid connecting shaft 4331 connected to the central partition 4321. The end of the rigid connecting shaft 4331 is a screw-in section 4332. The screw-in section 4332 extends to the outside of the inner mounting bucket 21. The screw-in section 4332 extends out of the inner mounting bucket 21 and cooperates with several locking nuts 4333. The locking nuts 4333 press against the outer wall of the inner mounting bucket 21, setting the rear section of the rigid connector 433 as the screw-in section 4332. The rear end of the rigid connector 433 is tightly fixed by the cooperation of the locking nuts 4333, thereby tightening and fixing the connector 431 and the bidirectional buffer 432, ensuring the overall tightening and fixing effect.

[0037] Although the tensioning component 43 brings the guide steel 31 as close as possible to the tilting platform 20, some gaps are still unavoidable, and molten steel may overflow from these gaps. Therefore, this invention uses a surrounding mechanism 50 to create a surrounding structure 51 at the lower end of the tilting platform 20. This surrounding structure 51 forms an annular structure through which high-pressure gas can be introduced. High-pressure gas can then be injected into the gap between the guide steel 31 and the tilting platform 20, forcing the molten steel that might have overflowed from there back to the inside. This creates an air curtain that prevents molten steel from flowing out from this location, making it extremely suitable for high-temperature molten steel and avoiding the melting phenomenon that occurs with other contact-type sealing structures.

[0038] The entire guide steel 31 is blasted from a single piece of steel. In order to make it fit with the upper and lower structures, the guide steel 31 includes an inclined section 311 that supports the lower chute 32. The upper end of the inclined section 311 is provided with an upper horizontal section 312, which is integrally connected with the inner pull seat 41. The lower end of the inclined section 311 is provided with a lower horizontal section 313, so that the upper and lower ends can connect with the ladle and the inclined platform 20.

[0039] To make the guide steel 31 less labor-intensive when it is engaged with the tilting platform 20, the lower end of the leveling seat 22 is provided with two partition rails 221, and the upper horizontal section 312 is provided with grooves on both sides. When the guide steel 31 is engaged with the inner mounting bucket 21, the grooves engage with the partition rails 221, so that the guide steel 31 can be embedded according to the predetermined track.

[0040] The entire edging structure 51 needs to fully cover the gap between the guide steel 31 and the tilting platform 20. Therefore, the edging structure 51 in this embodiment includes an edging pipe 511 set on the partition rail 221. The edging pipe 511 is connected to at least one air pump. The air outlet cavity 52 is connected to the bottom surface of the partition rail 221 and the edge position does not exceed the partition rail 221. The edging pipe 511 of the edging structure 51 has a U-shaped structure, which completely surrounds the three sides of the guide steel 31 except for the feeding side, thereby forming a U-shaped air curtain structure, which tightly presses the molten steel that may overflow into the inner side of the partition rail 221.

[0041] During the process of molten steel feeding, a certain force is actually exerted on the entire guide steel 31, which may cause slight displacement of the guide steel 31 and increase the risk of leakage. Therefore, the vibration damping kit 53 of this embodiment includes a first punch pipe 531 and a second punch pipe 532 disposed on the outside of the inner mounting hopper 21. The first punch pipe 531 and the second punch pipe 532 are respectively connected to the liquid inlet end and the liquid outlet end. A connecting pipe 533 is opened at one end of the first punch pipe 531 and the second punch pipe 532 facing downward into the guide cavity 30. A quick-connect coupling is provided on the connecting pipe 533. The connecting pipe 533 is movably connected to a U-shaped circulation pipe 534 that is close to the lower end of the guide steel 31. The vibration damping kit 53 is divided into two parts, namely the two punch pipes and the U-shaped circulation pipe 534, so that multiple positions of the guide steel 31 can obtain the effect of water flow unloading. The flow of water is used to deal with the fluctuations caused by the continuous feeding of molten steel, making the entire structure more stable.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
