Description

Technical Field

[0001] This utility model relates to the field of silicon carbide ceramic lining technology, specifically a silicon carbide ceramic lining fixing and sealing device. Background Technology

[0002] Silicon carbide ceramic liners are lining structures made of silicon carbide ceramic materials and widely used in various industrial fields, playing an important protective and functional role. Here is a detailed introduction: Material Characteristics: High Hardness: Silicon carbide ceramics themselves have extremely high hardness, with a Mohs hardness of around 9.5, second only to diamond. This gives the linings excellent wear resistance, effectively resisting the erosion and friction of materials. They perform exceptionally well in environments prone to wear, such as mining grinding and coal conveying. High Temperature Resistance: They can withstand very high temperatures, typically operating stably at 1400℃ or even higher. They are suitable for high-temperature operating scenarios such as high-temperature kilns and metallurgical furnaces, providing a high-temperature protective barrier for the equipment interior.

[0003] Regarding the above technical solutions, the existing sealing devices do not have a good quick connection function, which is troublesome when connecting them, thus affecting the user experience. In addition, the overall length is fixed, so it is difficult to adjust the length according to actual needs, and therefore cannot be adjusted according to the length of the inner lining plate.

[0004] Therefore, this utility model provides a silicon carbide ceramic liner fixing and sealing device to solve the above problems. Utility Model Content

A length adjustment component 2 is connected to the inner wall of the fixing frame 1 via a bearing. Fixing components 3 are fixedly installed on both sides of the length adjustment component 2. A sealing component 4 is snapped into the inner wall of the fixing component 3. The fixing component 3 includes a fixing plate 31 and a sliding rod 32. The fixing plate 31 is fixedly installed on one side of the length adjustment component 2, and the sliding rod 32 is slidably connected to one side of the fixing plate 31. A triangular block 33 is fixedly connected to one end of the sliding rod 32, and a spring 34 is sleeved on the side wall of the sliding rod 32. One end is fixedly connected to a limiting block 35. The sealing assembly 4 includes a ceramic liner body 41 and a protective plate 42. The ceramic liner body 41 is bolted to one side of the fixed frame 1. The protective plate 42 is set above the ceramic liner body 41. The sealing assembly 4 also includes a positioning rod 43 and a positioning groove 44. The positioning rod 43 is fixedly installed at the bottom of the protective plate 42. The positioning groove 44 is opened at the top of the ceramic liner body 41. The positioning rod 43 and the positioning groove 44 are engaged with each other. The sealing assembly 4 also includes a sealing gasket 45. The sealing gasket 45 is respectively set at the top and bottom of the ceramic liner body 41.

[0030] In this embodiment, pressing down the protective plate 42 can compress the triangular block 33. Then, the triangular block 33 will slide on one side of the fixed plate 31 via the slide rod 32. Then, the triangular block 33 will compress the spring 34 to retract. After that, the protective plate 42 will be engaged with the positioning groove 44 to fix the ceramic liner body 41. At the same time, the sealing gasket 45 can ensure the sealing between the protective plate 42 and the ceramic liner body 41.

[0031] Reference Figures 1 to 4In one aspect of this embodiment, the length adjustment assembly 2 includes a bidirectional threaded rod 21 and a movable frame 22. The bidirectional threaded rod 21 is connected to the inner side wall of the fixed frame 1 via a bearing. The movable frame 22 is threadedly connected to the side wall of the bidirectional threaded rod 21. A slider 23 is fixedly installed on the top of the movable frame 22. A groove 24 is provided on the top of the fixed frame 1. The slider 23 is slidably connected to the groove 24. The length adjustment assembly 2 also includes a knob 25, which is fixedly connected to the side wall of the bidirectional threaded rod 21.

[0032] In this embodiment, the ceramic liner body 41 is first installed together with the fixed frame 1 using bolts. Then, by rotating the knob 25, the movable frame 22 can be moved by the bidirectional threaded rod 21. The movable frame 22 will slide inside the slide groove 24 through the slider 23, so that the fixed plate 31 can be adjusted according to the length of the ceramic liner body 41.

[0033] Working principle: First, the ceramic liner body 41 is installed together with the fixed frame 1 using bolts. Then, turning the knob 25 can drive the moving frame 22 to move through the bidirectional threaded rod 21. The moving frame 22 will slide inside the slide groove 24 through the slider 23, so that the fixed plate 31 can be adjusted according to the length of the ceramic liner body 41.

[0034] Pressing down the protective plate 42 further compresses the triangular block 33. The triangular block 33 then slides on one side of the fixed plate 31 via the slide bar 32. The triangular block 33 then compresses the spring 34 to retract. Afterward, the protective plate 42 is engaged with the positioning groove 44 to fix the ceramic liner body 41. At the same time, the sealing gasket 45 ensures the seal between the protective plate 42 and the ceramic liner body 41.
