[0039] Figure 2 This is a cross-sectional structural diagram showing the application state of a specific embodiment of the high-temperature resistant mud gun of the present invention.

[0040] like Figure 1 and Figure 2 As shown, the high-temperature resistant mud gun of this embodiment is used in the operation of industrial silicon furnace 1 to block the furnace hole 11 of industrial silicon furnace 1. During operation, the front end of the mud gun body 2 extends into the furnace hole 11, and the cover 21 covers the operating position of the mud gun body 2 to provide high-temperature protection.

[0041] Figure 3 This is a cross-sectional structural schematic diagram of a specific embodiment of the high-temperature resistant mud gun of the present invention.

[0042] Figure 4 This is a schematic diagram of the three-dimensional assembly structure of a specific embodiment of the high-temperature resistant mud gun of the present invention.

[0043] like Figure 3 and Figure 4As shown, the high-temperature resistant mud gun of this embodiment includes a mud gun body 2, a mud gun barrel 22, and a cover 21. The mud gun body 2 includes a gun barrel and a moving carrier, which is installed at the lower part of the gun barrel to move the gun barrel. The mud gun barrel 22 includes an mounting end and a working end. The mounting end is installed on the gun barrel of the mud gun body 2, and the working end is positioned close to the furnace body of the industrial silicon furnace 1 during operation, and can deliver plugging mud into the furnace eye 11. The cover 21 is a high-temperature resistant non-metallic material sleeve, fitted over the working end, covering the outside of the working end. The end of the cover 21 is closer to the interior of the industrial silicon furnace 1 during operation than the end of the mud gun barrel 22.

[0044] In this invention, a high-temperature resistant non-metallic material cover 21 is used. When the mud gun body 2 is operated, it can resist high-temperature erosion and improve the reliability of operation. Moreover, even if there is burn damage, because it is a non-metallic material, it will not cause pollution to the molten solution, thereby improving the quality of the final product.

[0045] In this embodiment, the sleeve 21 has a cylindrical structure, and the working end has a cylindrical structure. The inner wall of the sleeve 21 fits onto the outer circumferential surface of the working end to isolate the mud gun barrel 22 from the high temperature. In this embodiment, the sleeve 21 is connected to the sleeve base 23, and an anti-detachment ring 24 is connected to the working end. The anti-detachment ring 24 abuts against the end of the sleeve base 23 near the furnace body of the industrial silicon furnace 1 to prevent the sleeve 21 and the sleeve base 23 from detaching from the mud gun barrel 22. In this embodiment, a groove is provided on the working end, and the anti-detachment ring 24 is placed in the groove. The sleeve base 23 and the sleeve 21 are connected by bolts 25. This connection method is more reliable and convenient for disassembly and assembly. In this embodiment, the cover 21 is a graphite cover, which is made by processing electrode rods in an industrial silicon furnace, which can significantly save costs and reduce environmental pollution. In addition, the wall thickness of the graphite cover 21 is 5-8cm, preferably 7cm, to ensure its connection strength. The distance between the inner wall of the graphite cover 21 and the outer peripheral surface of the working end is 2.5-3.5mm, so as to maximize the heat insulation performance while meeting the working conditions.

[0049] Figure 8 This is a schematic diagram of the drive rod and pulley pair in a specific embodiment of the high-temperature resistant mud gun of the present invention.

[0050] like Figures 5 to 8As shown, in this embodiment, the side of the sleeve 23 away from the sleeve cover 21 is provided with a helical tooth 231 for transmission. Specifically, the helical tooth 231 is located on the end face of the step, and the helical tooth 231 drives the sleeve cover 21 to rotate relative to the working end through power input. By inputting power through the helical tooth 231, the sleeve cover 21 is driven to rotate, which facilitates the introduction of plugging mud into the furnace hole 11, and also facilitates uniform temperature and avoids unidirectional heating.

[0051] In the first embodiment, a drive rod 26 and a rotating hook 27 are installed on the mud gun barrel 22. The drive rod 26 connects to the rotating hook 27 and drives the rotating hook 27 to swing. The hook head 271 of the rotating hook 27 engages with the helical teeth 231 and can drive the sleeve 23 to rotate during rotation, thereby driving the sleeve 21 to rotate. In this embodiment, there are two sets of drive rods 26 and rotating hooks 27, symmetrically arranged relative to the mud gun barrel 22. This arrangement can improve driving stability and avoid deviation. In this embodiment, a pulley pair 28 is provided on the mud gun barrel 22. The pulley pair 28 is formed by the cooperation of a first pulley 281 and a second pulley 282. The drive rod 26 is clamped between the first pulley 281 and the second pulley 282 to improve the stability and flexibility of pushing and pulling. The pulley pair 28 can be one set, two sets, or more sets, depending on the actual situation.

[0052] In this embodiment, a manual operating device is provided at the end of the drive rod 26 away from the furnace body of the industrial silicon furnace 1 for manual operation. In other embodiments, a motor is connected to the end of the drive rod 26 away from the furnace body of the industrial silicon furnace 1 to achieve automated operation.

[0053] Figure 9 This is a schematic diagram of the driving structure of another specific embodiment of the high-temperature resistant mud gun of the present invention.

[0054] like Figure 9 As shown, in this embodiment, the side of the sleeve 23 away from the sleeve cover 21 is provided with a helical tooth 231 for transmission. Specifically, the helical tooth 231 is located on the end face of the step, and the helical tooth 231 drives the sleeve cover 21 to rotate relative to the working end through power input. By inputting power through the helical tooth 231, the sleeve cover 21 is driven to rotate, which facilitates the introduction of plugging mud into the furnace hole 11, and also facilitates uniform temperature and avoids unidirectional heating.

[0055] In this embodiment, a motor 29 is installed on the mud gun barrel 22. The power shaft of the motor 29 is connected to an output gear, which meshes with a helical gear 231. The wiring buckle of the motor 29 is located inside the outer wall of the mud gun barrel 22.

[0056] In addition, the present invention also discloses an industrial silicon tapping machine, which includes the high-temperature resistant mud gun as described above.

[0057] This industrial silicon tapping machine is used for tapping operations in industrial silicon furnaces. Other parts of the structure are not the subject of this invention patent. The specific structure can be referred to the structure of existing tapping machines, so they will not be described in detail here.

[0058] In this invention, a high-temperature resistant non-metallic material cover is used. When the mud gun is being operated, it can resist high-temperature erosion, improve the reliability of operation, and even if there is burn-off, it will not cause pollution to the molten solution because it is a non-metallic material, thereby improving the quality of the final product.

[0059] Those skilled in the art should understand that the specific structures and processes shown in the above detailed embodiments are merely exemplary and not restrictive. Furthermore, those skilled in the art can combine the various technical features described above in various possible ways to form new technical solutions or make other modifications, all of which fall within the scope of this invention.
