[0004] The prior art has the following technical defects: silicon-carbon rod may be broken due to thermal stress, mechanical stress, aging, oxidation or quality problems during use, and although the above-mentioned device can realize horizontal pulling out of silicon-carbon rod, it is not easy to take out the broken silicon-carbon rod. UTILITY MODEL CONTENTS

[0005] The utility model solves the technical problems: the problem that silicon-carbon rod is difficult to take out after breaking due to thermal stress, mechanical stress, aging, oxidation or quality problems is effectively solved, the deficiencies of the prior art are overcome, and a silicon-carbon rod replacement device for glass production is provided.

[0006] The utility model includes shell, the inside of shell is provided with a plurality of groups of support plate, one end of support plate is fixedly connected with positioning rotary shaft in symmetry, positioning rotary shaft is rotatably connected with shell, the inside of support plate is fixedly connected with fixed connecting rod, the outside of fixed connecting rod is rotatably connected with moving plate, the end of moving plate away from support plate is fixedly connected with connecting shaft in symmetry, the middle part of shell is provided with moving rod, moving rod is rotatably connected with connecting shaft.

[0007] A fixing plate is fixedly connected to the outside of the movable rod and to the inside of the outer shell. A spring is provided on the outside of the movable rod, and the two ends of the spring are fixedly connected to the fixing plate and the outer shell, respectively.

[0008] Multiple sets of fixing rings are fixedly connected to the inner side of the outer casing. The fixing rings are located outside the moving rod and are slidably connected to the moving rod.

[0011] A ceramic fiber block is fixedly connected to the end corner of the support plate away from the positioning rotation axis, utilizing the flexibility of the ceramic fiber block.

[0012] Working process or principle: The operator places the outer casing inside the silicon carbide rod, holds the casing with one hand, and grasps the moving rod with the other. The operator then pulls the moving rod outward from the inside of the casing, causing it to move the moving plate via the connecting shaft. Simultaneously, the support plate is positioned via the positioning rotating shaft, causing the moving plate to rotate around the positioning rotating shaft via the fixed connecting rod. Multiple sets of support plates rotating around the positioning rotating shaft cause the support plates to move the ceramic fiber blocks, holding the broken silicon carbide rod in place, thus enabling its removal. This improves replacement efficiency and reduces operational difficulty. When the device is not in use, the elasticity of the springs causes the fixed plate to move the moving rod. The movement of the moving rod is transmitted through the connecting shaft and the moving plate, causing the support plate to retract around the positioning rotating shaft. The synchronous retraction of multiple sets of support plates returns the device to its initial state for easy storage or future use.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the outer shell is placed inside the silicon carbide rod, and then the moving rod is pulled outward from the inside of the outer shell, so that the moving rod drives the moving plate to move through the connecting shaft. At the same time, the support plate is positioned through the positioning rotating shaft, so that the moving plate drives the support plate to rotate around the positioning rotating shaft through the fixed connecting rod. By having multiple sets of support plates rotate around the positioning rotating shaft, the support plate holds up multiple broken sections of silicon carbide rod, thereby realizing the removal of the broken silicon carbide rod, improving the replacement efficiency and reducing the difficulty of operation.

[0014] When the device is not in use, the elasticity of the spring causes the fixed plate to move the moving rod. The movement of the moving rod is transmitted through the connecting shaft and the moving plate, which in turn causes the support plate to retract around the positioning rotation shaft. Through the synchronous retraction of multiple sets of support plates, the device returns to its initial state, making it easy to store or use next time. Attached Figure Description

Detailed Implementation

[0020] Example 1

[0021] like Figs. 1-4 As shown, the device includes a housing 101. Multiple support plates 102 are arranged on the inner side of the housing 101. A positioning rotation shaft 103 is symmetrically fixedly connected to one end of each support plate 102. The positioning rotation shaft 103 is rotatably connected to the housing 101. A fixed connecting rod 104 is fixedly connected to the inner side of each support plate 102. A movable plate 105 is rotatably connected to the outer side of each fixed connecting rod 104. A connecting shaft 106 is symmetrically fixedly connected to the end of the movable plate 105 away from the support plate 102. A movable rod 107 is arranged in the middle of the housing 101. The movable rod 107 is rotatably connected to the connecting shaft 106. The shell 101 is placed inside the silicon carbide rod. Then, the moving rod 107 is pulled outward from the inside of the shell 101, so that the moving rod 107 drives the moving plate 105 to move through the connecting shaft 106. At the same time, the support plate 102 is positioned through the positioning rotating shaft 103. Then, the moving plate 105 drives the support plate 102 to rotate around the positioning rotating shaft 103 through the fixed connecting rod 104. By having multiple sets of support plates 102 rotate around the positioning rotating shaft 103, the support plates 102 hold up multiple broken silicon carbide rods, thereby realizing the removal of broken silicon carbide rods, improving replacement efficiency and reducing operation difficulty.

[0022] Multiple sets of fixing rings 301 are fixedly connected to the inner side of the outer shell 101. The fixing rings 301 are located on the outer side of the moving rod 107 and are slidably connected to the moving rod 107. The fixing rings 301 support the moving rod 107, thereby making it more stable when the operator pulls the moving rod 107.

[0023] A baffle 401 is fixedly connected to the outer side of the outer casing 101.

[0024] A handle 501 is fixedly connected to the outer side of one end of the movable rod 107, making it more convenient for the staff to pull the movable rod 107.

[0025] A ceramic fiber block 601 is fixedly connected to the end corner of the support plate 102 away from the positioning rotation shaft 103. The flexibility of the ceramic fiber block 601 allows the device to fit the silicon carbide rod more snugly.

[0026] During operation, the operator places the outer casing 101 inside the silicon carbide rod. Holding the casing 101 with one hand and the moving rod 107 via the handle 501 with the other, the operator pulls the moving rod 107 outward from the inside of the casing 101. This causes the moving rod 107 to move the moving plate 105 via the connecting shaft 106. Simultaneously, the positioning rotating shaft 103 positions the support plate 102, causing the moving plate 105 to rotate around the positioning rotating shaft 103 via the fixed connecting rod 104. Multiple sets of support plates 102 rotating around the positioning rotating shaft 103 cause the support plates 102 to drive the ceramic fiber blocks 601 to hold up multiple broken sections of the silicon carbide rod, thus enabling the removal of the broken silicon carbide rod. This improves replacement efficiency and reduces operational difficulty.

[0027] Example 2

[0028] like Figs. 3-4 As shown, a fixing plate 201 is fixedly connected to the outer side of the moving rod 107 and the inner side of the outer shell 101. A spring 202 is provided on the outer side of the moving rod 107. The two ends of the spring 202 are fixedly connected to the fixing plate 201 and the outer shell 101, respectively. When the device is not in use, the elasticity of the spring 202 causes the fixing plate 201 to move the moving rod 107. The movement of the moving rod 107 is transmitted through the connecting shaft 106 and the moving plate 105, which in turn causes the support plate 102 to retract around the positioning rotation shaft 103. Through the synchronous retraction of multiple sets of support plates 102, the device returns to its initial state, making it easy to store or use next time.
