Description

Technical Field

[0001] This utility model relates to the field of argon blowing connector technology, specifically a rotary ladle argon blowing connector. Background Technology

[0002] Argon blowing into the ladle, also known as argon blowing into molten steel, is a simple ladle refining method for degassing molten steel and removing non-metallic inclusions. This method is simple, requires inexpensive equipment, and has significant refining effects. The argon blowing connector is a key piece of equipment used to blow argon gas into molten steel during the steelmaking process. Its core function is to improve the purity and uniformity of the molten steel through the physical and chemical effects of argon gas.

[0003] Existing argon blowing connectors include an upper connector and a lower connector. The upper connector is connected to the bottom of the ladle. The lower connector is usually connected to the upper connector by a threaded connection. However, the connection lacks a reinforcement function, which may cause loosening during long-term use, posing a certain safety hazard and easily leading to leakage of the medium. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary ladle argon blowing joint, which improves the stability of the connection between the lower and upper joints, plays a good reinforcing role, avoids loosening during long-term use, and achieves multiple sealing effects to prevent media leakage. This solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary ladle argon blowing connector, comprising a lower connector and an upper connector disposed on the top of the lower connector, wherein an outer interface is fixed on the outer side of the lower connector, a positioning post is connected to the top of the outer interface, a pressing ring is movably connected to the outer side of the upper connector, a positioning groove matching the positioning post is provided at the bottom of the pressing ring, and a driving mechanism for driving the pressing ring to descend is connected to the pressing ring.

[0020] 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.

[0021] Please see Figures 1 to 5 This utility model provides a rotary ladle argon blowing connector, including a lower connector 1 and an upper connector 2 disposed on the top of the lower connector 1. An outer interface 7 is fixed to the outer side of the lower connector 1, and a positioning post 11 is connected to the top of the outer interface 7. The top of the positioning post 11 is a smooth surface, which can reduce the contact friction with the pressing ring 5. A pressing ring 5 is movably connected to the outer side of the upper connector 2. The bottom of the pressing ring 5 is provided with a positioning groove 12 that matches the positioning post 11, and the pressing ring 5 is connected to a drive mechanism for driving the pressing ring 5 to descend.

[0022] During the docking process between the lower connector 1 and the upper connector 2, the lower connector 1 is rotated to connect with the upper connector 2. The lower connector 1 gradually moves upward, simultaneously driving the outer interface 7 upward. The top of the positioning post 11 slides against the bottom of the pressing ring 5, at which point the spring 4 is gradually compressed. The connection between the lower connector 1 and the upper connector 2 is completed when the positioning post 11 connects with the positioning groove 12 at the bottom of the pressing ring 5. The pressing ring 5 prevents the outer interface 7 and the lower connector 1 from becoming loose, achieving good positioning. This improves the stability of the connection between the lower connector 1 and the upper connector 2, providing good reinforcement and preventing loosening during prolonged use.

[0023] The lower connector 1 is threadedly connected to the upper connector 2. The inner side of the upper connector 2 is provided with a sealing bevel 8, and the lower connector 1 is pressed against the sealing bevel 8.

[0024] The drive mechanism includes a spring seat 3, a spring 4, multiple sliding blocks 13, and multiple sliding grooves 14. The sliding grooves 14 match the sliding blocks 13, and the sliding blocks 13 guide the pressing ring 5. The spring seat 3 is connected to the outside of the upper connector 2, and the spring 4 drives the pressing ring 5 to move downward. The spring 4 has a large elastic value. After the lower connector 1 and the upper connector 2 are connected, the spring 4 applies a large pressure to the pressing ring 5, pressing the pressing ring 5 tightly against the outer interface 7. Combined with the use of the sealing gasket 10, the sealing performance of the connection between the two is improved.

[0025] The slide groove 14 is located on the outer side of the upper connector 2, and the sliding block 13 is slidably connected to the slide groove 14, while the sliding block 13 is fixedly connected to the pressing ring 5. When the pressing ring 5 moves, it can synchronously drive the sliding block 13 to slide within the slide groove 14, improving the stability of the pressing ring 5's movement and providing a good guiding effect. When the positioning post 11 is connected to the positioning groove 12, the pressing ring 5 serves to limit the movement of the external interface 7, preventing the lower connector 1 from rotating.

[0026] The depth of the positioning groove 12 is greater than the height of the positioning post 11, which ensures good contact between the sealing gasket 10 and the bottom of the pressing ring 5.

[0027] Spring 4 is fitted onto upper connector 2, and both ends of spring 4 are connected to spring seat 3 and pressing ring 5.

[0028] Multiple anti-slip protrusions 6 are connected to the outer side of the pressing ring 5. The anti-slip protrusions 6 can increase the friction with the hand, making it easier to raise the pressing ring 5.

[0029] The bottom of the upper connector 2 is provided with a sealing gasket 9, and the top of the outer interface 7 is provided with a sealing gasket 10. After the lower connector 1 and the upper connector 2 are connected, the lower connector 1 is pressed against the upper connector 2, and the sealing gaskets 9 and 10 are pressed together. The lower connector 1 is pressed against the sealing slope 8, thereby improving the tightness of the connection between the lower connector 1 and the upper connector 2, achieving a multiple sealing effect, and avoiding media leakage.

[0030] Working principle: When the lower connector 1 and upper connector 2 are connected, the lower connector 1 is driven to rotate, causing it to gradually move upward, simultaneously moving the outer interface 7 upward. The top of the positioning post 11 slides relative to the bottom of the pressing ring 5, gradually lifting the pressing ring 5 and compressing the spring 4. Until the positioning post 11 connects with the positioning groove 12, the pressing ring 5 presses tightly against the outer interface 7, completing the connection between the lower connector 1 and the upper connector 2. The pressing ring 5 serves to limit the movement of the outer interface 7 and the lower connector 1, preventing rotation and improving the stability of the connection between the lower connector 1 and the upper connector 2, thus providing a good reinforcement effect and preventing loosening during long-term use. The sealing gasket 1 9, sealing gasket 2 10, and sealing bevel 8 further enhance the tightness of the connection between the lower connector 1 and the upper connector 2, achieving a multiple sealing effect and preventing media leakage. When disassembling the lower connector 1, operate the anti-slip protrusion 6 to lift the pressing ring 5, so that the positioning post 11 is separated from the positioning groove 12, and then rotate the lower connector 1 to facilitate separation from the upper connector 2. The operation is simple, convenient and highly flexible.
