[0022] See also Figure 1-4 , the utility model provides the following two technical solutions:

[0023] Example 1

[0024] A converter device with a gas detection mechanism for steel smelting includes a gas filter box 1 and a filter device 2 located inside the gas filter box 1. The gas filter box 1 and the filter device 2 are detachably connected via a connecting component 3. The connection component 2 is provided so that the filter device 2 can be easily disassembled when it is necessary to clean or replace it.

[0025] Among them, for the specific detection structure of the coal gas in the converter, please refer to the patent "A converter device with a coal gas detection mechanism for steel smelting" (publication number CN216141574U, publication date 2022-03-29).

[0026] Among them, regarding the design scheme of the connecting component 3, the connecting component 3 includes a plug-in component 31 for limiting the bottom of the filter device 2, and a locking component 32 for limiting the top of the filter device 2. By setting the plug-in component 31, the bottom of the filter device 2 is limited, effectively preventing its position from deflecting. By setting the locking component 32, the filter device 2 after the bottom is limited is further limited, so as to be fixed.

[0027] Among them, regarding the design scheme of the plug-in connector 31, the plug-in connector 31 includes a plug-in rod 311 fixedly arranged on the inner bottom wall of the gas filter box 1, and the bottom of the filter device 2 is recessed inward to form a plug-in groove, and the plug-in rod 311 can be engaged with the inside of the plug-in groove. When installing the filter device 2, the filter device 2 is inserted along the inner wall of the gas filter box 1, and the plug-in groove at the bottom is aligned with the plug-in rod 311 and inserted, thereby preliminarily limiting the position of the filter device 2, so that after installation, the bottom cannot move.

[0028] Among them, regarding the design scheme of the locking member 32, the locking member 32 includes a locking groove 321 provided on the top of the gas filter box 1, a locking block 322 is slidably provided inside the locking groove 321, a slot 323 is provided on one side of the locking block 322, and the top corner of the filter device 2 is engaged with the inside of the slot 323. When the filter device 2 is fully inserted into the gas filter box 1, the locking block 322 is pushed along the locking groove 321, so that the slot 323 on the locking block 322 is engaged with the corner of the filter device 2, thereby limiting and fixing the filter device 2; when the filter device 2 needs to be disassembled, the locking block 322 is pushed along the inside of the locking groove 321.

[0029] As a further technical solution, an elastic component 324 is fixedly arranged inside the locking groove 321. The elastic component 324 is a spring, and its elastic coefficient can be set according to requirements. One end of the elastic component 324 is fixedly connected to the locking block 322. When the elastic component 324 is not subject to external force and is at its original length, it drives one side of the locking block 322 to move out of the locking groove 321. At this time, the slot 323 is completely engaged with the corner of the filter device 2.

[0030] As a further technical solution, both sides of the top of the locking block 322 extend outward to form protrusions 325, and the setting of the protrusions 325 facilitates manual operation of the locking block 322. The bottom of the protrusion 325 is fixedly provided with a sliding column 326 that is slidably connected to the gas filter box 1. The setting of the sliding column 326 effectively improves the stability of the locking block 322 during movement.

[0031] As a further technical solution, a slide groove 327 is provided on the top of the gas filter box 1, and the outer surface of the sliding column 326 is slidably connected to the inner surface of the slide groove 327. The cooperation between the slide groove 327 and the sliding column 326 can not only improve the stability of the locking block 322 during the movement, but also limit the moving distance driven by the locking block 322 to prevent it from moving out of the locking groove 321.

[0032] As a further technical solution, one side of the top of the locking block 322 is an inclined surface. When installing the filter device 2, the two sides of its bottom can act on the inclined surface of the locking block 322. By pressing down the filter device 2, the locking block 322 can be pushed into the locking groove 321 through the inclined surface. After the filter device is completely moved into the gas filter box 1, under the reset action of the elastic component 324, the locking groove 323 on the locking block 322 is driven to fully engage with the corner of the filter device 2, so that the installation of the filter device 2 is realized; when disassembling the filter device 2, the protrusion 325 is pushed to drive the locking block 322 to move into the locking groove 321. This technical solution has a simple structure and is easy to operate.

[0033] Example 2

[0034] A converter device with a gas detection mechanism for steel smelting includes a gas filter box 1 and a filter device 2 located inside the gas filter box 1. The gas filter box 1 and the filter device 2 are detachably connected via a connecting component 3. The connection component 2 is provided so that the filter device 2 can be easily disassembled when it is necessary to clean or replace it.

[0035] Among them, for the specific detection structure of the coal gas in the converter, please refer to the patent "A converter device with a coal gas detection mechanism for steel smelting" (publication number CN216141574U, publication date 2022-03-29).

[0036] Among them, regarding the design scheme of the connecting component 3, the connecting component 3 includes a plug-in component 31 for limiting the bottom of the filter device 2, and a locking component 32 for limiting the top of the filter device 2. By setting the plug-in component 31, the bottom of the filter device 2 is limited, effectively preventing its position from deflecting. By setting the locking component 32, the filter device 2 after the bottom is limited is further limited, so as to be fixed.
