Description

Technical Field

[0001] This utility model relates to the field of argon blowing connector technology, specifically an easy-to-operate argon blowing connector for steel ladles. Background Technology

[0002] In the metallurgical and steel manufacturing industry, the bottom-blowing argon process is a crucial step in steelmaking and ladle refining. This process involves a bottom-blowing argon control system connected to the permeable bricks at the bottom of the ladle via a blowing connector. Argon gas is blown into the molten steel through this system, dispersing as bubbles and rising to the surface. The surrounding molten steel, propelled by buoyancy, flows within the ladle, accelerating the melting of alloys and solvents added to the steel and promoting uniformity in composition and temperature. Simultaneously, gases and inclusions in the molten steel are also accelerated to the surface by the argon bubbles, facilitating the removal of non-metallic inclusions and harmful gases, thus purifying and refining the molten steel.

[0003] The authorized publication number is CN221443595U, titled "A Steel Ladle Argon Blowing Connection Structure." It mentions that "rotating the torsion block 5 or the anti-slip plate 6 allows the connecting pipe 2 to rotate into the conduit 1. Because the front end of the guide pipe 3 is arc-shaped, it can move along the inside of the conduit 1. Since the opening inside the conduit 1 gradually decreases from right to left, the connecting pipe gradually approaches the center position and eventually becomes concentric with the conduit 1. At this point, rotating the torsion block 5 or the anti-slip plate 6 allows the connecting pipe 2 to be embedded into the conduit 1, achieving a better connection effect." However, the torsion block 5 or the anti-slip plate 6 lacks a corresponding positioning function. During the smelting process, the steel ladle will experience vibrations. Since the connecting pipe 2 is only connected to the conduit 1 by threads, it will inevitably loosen, leading to gas leakage and posing a significant safety hazard. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-operate argon blowing connector for steel ladles, comprising an upper connector and a lower connector connected to the bottom of the upper connector. An end cap is connected to the outer side of the upper connector, and a rotating ring is rotatably connected to the end cap.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 7 This utility model provides an easy-to-operate argon blowing connector for steel ladles, including an upper connector 1 and a lower connector 3 connected to the bottom of the upper connector 1. An end cap 2 is fixedly connected to the outer side of the upper connector 1. A rotating ring 4 is rotatably connected to the end cap 2, and a spring seat 6 is connected to the rotating ring 4. The spring seat 6 matches a connecting seat 7 connected to the outer side of the lower connector 3, and the spring seat 6 is connected to a positioning mechanism for positioning the connecting seat 7. Multiple connecting blocks 13 are connected inside the lower connector 3, and a limiting mechanism for limiting the movement of the connecting blocks 13 is connected to the rotating ring 4.

[0024] When connector 3 is connected to connector 1, rotate the rotating ring 4 in the following direction: Figure 1 and Figure 7 As indicated by the middle arrow, the rotating ring 4 applies a pushing force to multiple push-pull plates 11. The push-pull plates 11 push the corresponding clamping blocks 12 forward until the clamping blocks 12 press against the connecting block 13, thereby locking and fixing the lower connector 3, improving the stability of the connection between the lower connector 3 and the upper connector 1, replacing the traditional threaded connection method, and achieving high installation efficiency.

[0025] The positioning mechanism includes a positioning rod 5, a spring 15, a guide groove 16, a guide block 17, and an inclined surface 18. The guide block 17 guides the positioning rod 5. The guide groove 16 is located within the spring seat 6, and the guide block 17 is slidably connected to the guide groove 16. The spring 15 drives the positioning rod 5 to move closer to the connecting seat 7. The inclined surface 18 is located at the bottom of the positioning rod 5. During the rotation of the rotating ring 4, the side of the connecting seat 7 slides relative to the inclined surface 18, which can lift the guide block 17 and the positioning rod 5. The spring 15 is compressed until the clamping block 12 presses against the connecting block 13. At this point, the positioning rod 5 aligns with the limiting hole of the connecting seat 7. The compressed spring 15 drives the guide block 17 and the positioning rod 5 back to their original positions, connecting the positioning rod 5 with the limiting hole, thus limiting the rotation ring 4 and preventing it from loosening due to ladle vibration, which would affect the stability of the connection between the lower connector 3 and the upper connector 1. Furthermore, when limiting the rotation ring 4, it is not necessary to manually lift the positioning rod 5; simply rotating the rotating ring 4 is sufficient to achieve its limiting.

[0026] The guide block 17 slides within the guide groove 16, improving the stability of the positioning rod 5 during lifting and lowering, and achieving a good guiding purpose.

[0027] Spring 15 is located in guide groove 16, and both ends of spring 15 are connected to guide block 17 and spring seat 6. Guide block 17 is fixedly connected to positioning rod 5.

[0028] The connecting seat 7 is provided with a limiting hole that matches the positioning rod 5. The cross-section of the positioning rod 5 is a T-shaped structure. When the rotating ring 4 is loosened, the positioning rod 5 is pulled up to separate the positioning rod 5 from the limiting hole. Then the rotating ring 4 is rotated back, and the rotating ring 4 pulls multiple push-pull plates 11 to move backward. The push-pull plates 11 drive the pressing block 12 to move backward, so that the pressing block 12 is separated from the connecting block 13, thereby loosening the lower connector 3 and facilitating disassembly.

[0029] The limiting mechanism includes multiple limiting seats 10, multiple push-pull plates 11, multiple clamping blocks 12, and multiple limiting grooves 14. The two ends of the push-pull plates 11 are axially connected to the rotating ring 4 and the clamping blocks 12. The clamping blocks 12 are movably connected to the limiting seats 10. The limiting seats 10 are fixed within the upper connector 1. The limiting grooves 14 are located within the limiting seats 10 and match the connecting blocks 13. During the installation of the lower connector 3, the connecting blocks 13 are aligned with the limiting grooves 14, and then the lower connector 3 is pushed upwards, causing the connecting blocks 13 to insert into the limiting grooves 14. The lower connector 3 stops moving when the connecting blocks 13 are connected to the ends of the limiting grooves 14, facilitating the subsequent connection of the clamping blocks 12 and connecting blocks 13, thus achieving initial installation of the lower connector 3 and preventing rotation.

[0030] The clamping block 12 is slidably connected to the limiting seat 10, which improves the stability of the reciprocating movement of the clamping block 12 and prevents the clamping block 12 from being unable to detach from the limiting seat 10.

[0031] The outer side of the rotating ring 4 is provided with multiple sets of anti-slip grooves, which increase the friction with the hand and facilitate the operation of the rotating ring 4. The top of the rotating ring 4 is connected to an annular guide plate 8, which is slidably connected to the end cap 2. The rotation of the rotating ring 4 can drive the annular guide plate 8 to rotate, which guides the rotating ring 4 and improves the stability of the rotation.

[0032] The upper connector 1 has a sealing surface 9 on its inner side. When the clamping block 12 is pressed against the connecting block 13, the lower connector 3 is pressed against the sealing surface 9, which improves the sealing performance of the connection between the upper connector 1 and the lower connector 3 and avoids argon gas leakage.

[0033] Working principle: When installing the lower connector 3, insert the lower connector 3 into the upper connector 1, allowing the connecting block 13 to slide on the limiting groove 14 within the limiting seat 10. The end of the connecting block 13 connects with the end of the limiting groove 14, achieving initial installation and limiting of the lower connector 3. Then, rotate the rotating ring 4, which applies a pushing force to multiple push-pull plates 11. The push-pull plates 11 push the clamping block 12 forward until the clamping block 12 presses against the connecting block 13, thus fixing the lower connector 3 in place and improving the stability of the connection between the lower connector 3 and the upper connector 1. Combined with the use of the sealing surface 9, this improves the sealing performance of the connection and prevents argon gas leakage. At the same time, the positioning rod 5 connects to the limiting hole of the connecting seat 7, achieving limiting and fixing of the rotating ring 4. When the upper connector 3 needs to be disassembled, pull the positioning rod 5 upward, which simultaneously drives the guide block 17 upward. The spring 15 is compressed, and the positioning rod 5 separates from the limiting hole, thereby loosening the rotating ring 4. Then rotate the rotating ring 4, which applies a pulling force to multiple push-pull plates 11. The push-pull plates 11 pull the clamping block 12 backward, causing the clamping block 12 to separate from the connecting block 13, thereby loosening the upper connector 1. Finally, the upper connector 1 can be pulled out. The operation is simple and convenient.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
