Description

Technical Field

[0001] This utility model relates to the field of melt forming, specifically a melt forming device for thick-walled quartz tubes. Background Technology

[0002] Quartz tubes possess multiple advantages due to their high-purity silica material: high temperature resistance, strong thermal shock resistance, low coefficient of expansion, resistance to sudden cooling and heating, high chemical inertness, resistance to acids and organic solvents (except hydrofluoric acid), excellent light transmittance in the ultraviolet to infrared band, and high electrical insulation and mechanical strength. These properties make them widely used in semiconductor diffusion furnaces, photovoltaic single crystal furnaces, ultraviolet optical instruments, laser devices, high-purity chemical reaction vessels, and high-temperature observation windows, and they are irreplaceable, especially in fields requiring high temperature resistance, high purity, or ultraviolet transmittance.

[0003] In the production process of quartz tubes, high-purity quartz sand is required as a raw material for high-temperature melting. High-temperature melting can not only completely eliminate air bubbles and impurities in the raw material, but also promote the full homogenization of silica molecules, ensuring the optical uniformity and thermal stability of the final product. However, high-temperature melting has the problem of slow heating, which affects the production speed and thus leads to lower profits. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model include:

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0024] A thick-walled quartz tube melting and forming device includes a housing 1, with four partitions 2 installed inside the housing 1. A heating furnace 3 is connected inside the housing 1, and an electromagnetic coil 4 is installed on the outer surface of the heating furnace 3. A discharge pipe 5 is opened at the bottom of the housing 1. A connecting shaft 6 is rotatably installed inside the housing 1, and a valve plate 7 is connected to the right end of the connecting shaft 6. When the electromagnetic coil 4 on the outer surface of the heating furnace 3 is energized, the electromagnetic energy is converted into heat energy using the principle of electromagnetic induction, so that the raw material is rapidly heated to a molten state. The gear A10 at the output end of the motor 9 starts to rotate, and drives the gear B11 to rotate through meshing. Since the gear B11 is connected to the connecting shaft 6, the connecting shaft 6 rotates accordingly, which in turn drives the valve plate 7 at its right end to rotate, thereby realizing the opening of the discharge pipe 5 and the adjustment of the discharge speed.

[0025] In this embodiment, a fixing plate 8 is installed on the outer surface of the housing 1, and a motor 9 is installed on the upper surface of the fixing plate 8. The fixing plate 8 can fix the motor 9.

[0026] In this embodiment, a gear A10 is installed at the output end of the motor 9, and a gear B11 meshes with the outer surface of the gear A10. The interior of the gear B11 is connected to the end of the connecting shaft 6 away from the valve plate 7. The gear A10 can drive the gear B11 to rotate through meshing.

[0027] In this embodiment, the outer surface of the discharge pipe 5 penetrates the bottom of the box 1 and is connected to the collection box 12. The outer surface of the collection box 12 is connected to multiple molds 13. The molten quartz raw material flows into the collection box 12 through the discharge pipe 5.

[0028] In this embodiment, a top cover 20 is hinged to the upper surface of the heating furnace 3, a handle 21 is installed on the upper surface of the top cover 20, and a connecting pipe 25 is installed inside the top cover 20. The top cover 20 can be opened by using the handle 21.

[0029] In this embodiment, a fixing frame 15 is installed on the outer surface of the box 1, and a gas cylinder 16 is provided on the upper surface of the fixing frame 15. A valve 17 is provided at the output end of the gas cylinder 16, and the valve 17 can adjust the amount of gas output.

[0030] In this embodiment, the output end of the gas cylinder 16 is connected to a check valve 18, and the outer surface of the check valve 18 is connected to a gas pipe 19. The end of the gas pipe 19 away from the gas cylinder 16 is connected to the outer surface of the connecting pipe 25. The inert gas in the gas cylinder 16 prevents the quartz raw material from oxidizing at high temperature or reacting with impurities in the air to ensure purity.

[0031] In this embodiment, two ventilation openings 22 are opened on the outer surface of the housing 1, and two support shells 24 are installed on the outer surface of the housing 1. A fan 23 is installed inside the support shell 24, and a control module 14 is installed on the outer surface of the housing 1. The fan 23 introduces external air into the housing 1 through the ventilation openings 22 to accelerate the dissipation of internal heat, prevent the equipment from being damaged due to overheating, and ensure the normal operation of each component.

[0032] Working principle: Quartz raw material is placed into heating furnace 3. The operator turns on the equipment through control module 14. At this time, the electromagnetic coil 4 on the outer surface of heating furnace 3 is energized, and the electromagnetic induction principle is used to convert electrical energy into heat energy, so that the raw material is heated to a molten state quickly. The partition 2 can isolate most of the heat of heating furnace 3, preventing the life of various components in the box 1 from being shortened due to high temperature. The partition 2 can also strengthen the structure. At the same time, the valve 17 of gas cylinder 16 is opened, and inert gas is introduced into heating furnace 3 through check valve 18 and gas pipe 19 to form a protective atmosphere, preventing the quartz raw material from oxidizing at high temperature or reacting with impurities in the air, thus ensuring the purity of the raw material. The operator can open the top cover 20 through the handle 21 on the top cover 20 to add raw material or check the condition inside the furnace. When the quartz... After the raw materials are completely melted, the motor 9 starts, and the gear A10 at the output end of the motor 9 begins to rotate. Through meshing, it drives the gear B11 to rotate. Since the gear B11 is connected to the connecting shaft 6, the connecting shaft 6 rotates accordingly, which in turn drives the valve plate 7 at its right end to rotate, thereby opening the discharge pipe 5 and adjusting the discharge speed. The control module 14 can precisely control the speed of the motor 9 according to the preset program and the operator's instructions, thereby precisely adjusting the rotation angle of the valve plate 7 and stably controlling the discharge amount of molten quartz material. During the operation of the device, the two fans 23 on the outer surface of the housing 1 are fixedly installed through the support shell 24 and run continuously, introducing external air into the housing 1 through the ventilation port 22 to accelerate the dissipation of internal heat, prevent the equipment from being damaged due to overheating, and ensure the normal operation of each component.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
