[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 7 , the present invention provides a technical solution: A large-diameter gas-electric fused quartz ingot preparation device includes a body 11, the inner surface of the body 11 is fixedly connected to a fixing seat 25, the inner surface of the fixing seat 25 is provided with a forming assembly, the forming assembly includes a forming tube 23 fixedly connected to the fixing seat 25, the inner surface of the body 11 is provided with a spiral groove 18, the inner side of the body 11 is provided with a moving part, the body 11 is slidably connected to a movable plate 19 through the moving part, the outer surface of the upper end of the movable plate 19 is fixedly connected to a motor 20, the upper end of the output shaft of the motor 20 is fixedly connected to a driving rod 22, the upper end of the driving rod 22 is fixedly connected to a target holder 27, the target holder 27 is located on the inner side of the forming tube 23 and is in sliding contact with the inner surface of the forming tube 23, the outer surface of the driving rod 22 is fixedly connected to a fixing plate 21, the outer surface of the fixing plate 21 is fixedly connected to a rotating sleeve 42, and the body 11 is spirally connected to the rotating sleeve 42 through the spiral groove 18.

[0021] The upper and lower ends of the forming tube 23 are open, the outer surface of the upper end of the body 11 is fixedly connected to a fixing tube 16, the fixing seat 25 is annular, the fixing tube 16 is communicated with the inside of the forming tube 23, the lower end of the body 11 is open, the body 11 is made of heat-insulating material, the outer surface of the lower end of the body 11 is fixedly connected to a support leg 12, the forming assembly is used for quartz ingot processing and shaping, the moving part includes a guide groove 17 opened on the inner surface of the body 11, and a guide block 43 is slidably connected to the inside of the guide groove 17. The number of the guide grooves 17 and the guide blocks 43 are both two groups and are symmetrically distributed. The two groups of guide blocks 43 are fixedly connected to the movable plate 19.

[0022] By adopting the above technical solution, when the quartz ingot preparation device is working, the support legs 12 fix the body 11 to keep a certain distance between the lower end of the body 11 and the ground to facilitate the removal of the quartz ingot, and the quartz powder is evenly put into the fixed tube 16. The quartz powder melts into a molten state under the action of high temperature and gathers on the upper side of the target holder 27. The motor 20 fixes and supports the target holder 27 through the driving rod 22. The target holder 27 is located inside the forming tube 23. The target holder 27 cooperates with the forming tube 23 to enable the molten quartz material to gradually accumulate and form on the surface of the target holder 27. The target holder 27 will drive the quartz ingot on its upper side to move synchronously, thereby reducing the probability of adhesion between the quartz ingot and the forming tube 23 to a certain extent, thereby ensuring the forming quality of the quartz ingot. The body 11 supports the movable plate 19 slidingly through the guide groove 17 and the guide block 43, so that the movable plate 19 can slide linearly inside the body 11. When the output shaft of the motor 20 drives the driving rod 22 to rotate, The driving rod 22 will drive the fixed plate 21 to rotate synchronously, thereby driving the rotating sleeve 42 to rotate synchronously through the fixed plate 21. The rotating sleeve 42 is connected to the machine body 11 through the spiral transmission of the spiral groove 18. During the rotation, it will slide downward along the inner wall of the machine body 11. During the movement, the fixed plate 21 will drive the movable plate 19 to move downward synchronously through the driving rod 22 and the motor 20, so that the target holder 27 gradually moves downward from the inside of the forming tube 23. As the quartz material continues to accumulate on the target holder 27, the target holder 27 cooperates with the forming tube 23 to process the quartz material into a cylindrical shape, so that the quartz powder can be processed into a quartz ingot. By setting a forming assembly, the target holder 27 will move downward synchronously during the rotation inside the forming tube 23, so that the forming length of the quartz ingot can be gradually increased. By controlling the amount of quartz powder fed, it can be processed into quartz ingots of various sizes, thereby effectively improving the convenience and processing accuracy of the quartz ingot preparation device during use.

[0023] Specifically, such as Figure 4 and Figure 5As shown, a hot melt component is provided on the outside of the body 11, and the hot melt component includes a plasma flame generator 15 fixedly connected to the outer surface of the body 11. The plasma flame generator 15 is distributed in a circular ring shape on the outside of the body 11, and a flow equalizing plate 24 is embedded in the outer surface of the body 11. The flow equalizing plate 24 is distributed corresponding to the plasma flame generator 15.

[0024] A sealing plate 29 is fixedly connected to the inner surface of the body 11. The sealing plate 29 is annular. The inner surface of the sealing plate 29 is fixedly connected to the forming tube 23. An oxyhydrogen flame generator 31 is fixedly connected to the inner surface of the body 11. The oxyhydrogen flame generator 31 is distributed in an annular shape outside the forming tube 23. Flame holes 32 are opened on the outer surface of the oxyhydrogen flame generator 31. The number of the flame holes 32 is several groups and distributed in an annular array.

[0025] By adopting the above technical solution, when the quartz powder is added, it will fall down along the inside of the fixed tube 16 under the action of gravity. At this time, the plasma flame generator 15 will spray a high-temperature flame to melt the quartz powder. The flow plate 24 corresponding to the plasma flame generator 15 can improve the uniformity of the flame airflow, so that the quartz powder is evenly heated and melted. After the melted quartz material is collected on the surface of the target holder 27, in order to improve the forming accuracy of the quartz ingot, a high-temperature flame is generated by the hydrogen-oxygen flame generator 31, and then the flame passes through the flame nozzle 32 to continue to heat the quartz ingot accumulated on the surface of the target holder 27, so that the quartz ingot can be kept The quartz ingot is kept in a molten state, and the sealing plate 29 can separate the internal space of the body 11, thereby preventing the high-temperature gas from spreading outward from the lower side of the body 11, thereby improving the heat utilization efficiency, and helping the quartz ingot to evenly cover the surface of the target holder 27, thereby reducing the probability of gaps in the middle of the quartz ingot, and further improving the molding accuracy of the quartz ingot. As the target holder 27 gradually moves downward, the quartz ingot on the lower side will gradually move away from the flame generated by the oxyhydrogen flame generator 31, so that the quartz ingot on the lower side will gradually cool and take shape, and the oxyhydrogen flame generator 31 will continue to heat the newly melted quartz ingot.

[0026] Specifically, such as Figure 3 、 Figure 4 and Figure 5 As shown, a spoiler assembly is provided on the upper side of the sealing plate 29, and the spoiler assembly includes a movable frame 28 rotatably connected to the outer surface of the forming tube 23, the outer surface of the movable frame 28 is fixedly connected to a support frame 35, the outer surface of the support frame 35 is fixedly connected to a movable rod 34, and the upper side of the outer surface of the movable rod 34 is fixedly connected to a spoiler 33.

[0027] The movable frame 28 is annular, and the movable rods 34 and spoilers 33 are in several groups and distributed in an annular array. The height of the spoiler 33 corresponds to the flame nozzle 32. The spoiler 33 is arranged in an inclined shape and is made of high-temperature resistant material.

[0028] By adopting the above technical solution, the high-temperature flame airflow will blow the spoiler 33 when it is ejected from the flame nozzle 32. The movable frame 28 fixes the movable rod 34 through the support frame 35. The spoiler 33 will drive the movable frame 28 to rotate along the surface of the forming tube 23 under the push of the flame airflow. The movement of the spoiler 33 can play a certain guiding and diverting role on the flame airflow, so that the high-temperature flame can be evenly contacted with the outer surface of the forming tube 23, and the heating uniformity of the quartz ingot can be further improved, thereby reducing the risk of gaps and pores in the middle of the quartz ingot, which helps to improve the forming accuracy of the quartz ingot.

[0029] Specifically, such as Figure 4 and Figure 5 As shown, a reflux component is provided on the outside of the body 11, and the reflux component includes a storage tube 13 fixedly connected to the outer surface of the body 11, and the storage tube 13 is distributed in a circular shape on the outside of the body 11. A through groove 26 is provided on the outer surface of the body 11, and the upper outer surface of the sealing plate 29 is fixedly connected to the guide plate 30, and the upper outer surface of the guide plate 30 is inclined. The inner side of the body 11 is connected to the inner surface of the storage tube 13 through the through groove 26, and the lower end of the movable rod 34 is fixedly connected to the scraper 44, and the scraper 44 is in sliding contact with the upper outer surface of the guide plate 30. The outer surface of the storage tube 13 is fixedly connected to the conduit 14.

[0030] By adopting the above technical solution, when the oxyhydrogen flame generator 31 is working, hydrogen and oxygen are generated by electrolyzing water, and then the two are mixed at an optimal combustion ratio and ignited to form a high-temperature oxyhydrogen flame. Water is produced during the combustion of hydrogen and oxygen. In order to improve the utilization efficiency of water and reduce the evaporation of water, a reflux component is provided. The water produced by the oxyhydrogen flame generator 31 during combustion will gather on the surface of the guide plate 30, and the guide plate 30 will guide the water to the through groove 26, so that the water enters the storage tube 13 through the through groove 26. When the movable frame 28 drives the movable rod 34 and the spoiler 33 to rotate, the movable The rod 34 will drive the scraper 44 on its lower side to move synchronously. Through the sliding contact between the scraper 44 and the upper side of the guide plate 30, the water on the surface of the guide plate 30 can be discharged to the inside of the storage tube 13 in time, thereby effectively shortening the time that water stays on the surface of the guide plate 30, thereby effectively reducing the evaporation of water on the surface of the guide plate 30, and further reducing the raw material loss of the quartz ingot preparation device, thereby reducing the quartz ingot preparation processing cost to a certain extent, and water can be continuously injected into the storage tube 13 through the conduit 14, thereby ensuring the continuous operation of the quartz ingot preparation device.

[0031] Specifically, such as Figure 4 and Figure 6 As shown, a swing assembly is provided between the forming tube 23 and the body 11, and the swing assembly includes a mounting plate 36 fixedly connected to the inner surface of the body 11, a traction bar 37 is fixedly connected to the outer surface of the lower end of the mounting plate 36, and a contact block 39 is fixedly connected to the lower end of the traction bar 37, and the outer surface of the contact block 39 is arc-shaped, and an elastic plate 38 is fixedly connected between the traction bar 37 and the body 11.

[0032] The elastic plate 38 has a U-shaped structure, and the outer surface of the upper end of the fixed plate 21 is fixedly connected to a connecting rod 40. The upper end of the connecting rod 40 is fixedly connected to a sphere 41. The sphere 41 is in sliding contact with the outer surface of the contact block 39. The number of the contact blocks 39 and the traction bars 37 are both in several groups and distributed in a ring array.

[0033] By adopting the above technical solution, in order to further reduce the probability of pores forming in the middle of the quartz ingot, a swinging assembly is set. The body 11 fixes and supports the traction bar 37 through the mounting plate 36, and the mounting plate 36 supports and pulls the contact block 39 through the traction bar 37. The elastic plate 38 can apply a certain elastic force to the traction bar 37, so that the traction bar 37 remains tilted. During the rotation of the fixed plate 21, the ball 41 will be driven to move synchronously through the connecting rod 40. During the rotation, the ball 41 will contact the outer surface of the contact block 39. At this time, the ball 41 will squeeze and push the contact block 39, so that the contact block 39 When the ball 41 moves to the side away from the forming tube 23, the contact block 39 squeezes the elastic plate 38 through the traction bar 37 during the movement. When the ball 41 loses contact with the contact block 39, the traction bar 37 drives the contact block 39 to move in the opposite direction under the elastic force of the elastic plate 38, so that the contact block 39 collides with the forming tube 23. The collision can cause the forming tube 23 and the target holder 27 to vibrate. After the vibration wave is transmitted to the inside of the quartz ingot through the target holder 27, it will accelerate the discharge of the gas inside the quartz ingot, thereby reducing the generation of pores inside the quartz ingot, and further effectively improving the preparation and processing quality of the quartz ingot.
