Description

Technical Field

[0001] This invention relates to the field of silicon dioxide phase change technology, and more specifically to a high-purity silicon dioxide high-temperature phase change furnace. Background Technology

[0002] Silica (SiO2) is one of the most abundant oxides in the Earth's crust. Its phase structure plays a decisive role in material properties. Different crystal forms of silica differ significantly in terms of hardness, coefficient of thermal expansion, light transmittance, and chemical stability. A silica phase change furnace is a specialized heat treatment device that precisely controls the temperature and atmosphere for the phase transformation of silica. Its core function is to induce reversible or irreversible phase changes in silica by controlling parameters such as temperature, pressure, and atmosphere. It is widely used in high-end manufacturing fields such as semiconductors, photovoltaics, special glasses, and refractory materials. However, when performing phase change treatment on silica, a stable environment is required for atomic rearrangement of silica materials, and sufficient gaps need to be reserved between materials to ensure uniform heating.

[0003] The existing technology has the following problems:

[0004] 1. In the operation of existing high-purity silica high-temperature phase change furnaces, the silica material requires a stable environment for atomic rearrangement, which causes the drum to rotate at a very low speed, making it difficult to achieve the purpose of uniform heating of the silica material.

[0005] 2. In the process of using existing high-purity silica high-temperature phase change furnaces, granular silica is usually used for phase change treatment to facilitate subsequent processing. However, when performing high-temperature phase change on granular materials, it is difficult to leave enough gaps between the materials, which leads to an increase in temperature inside the material particle pile, resulting in the failure of silica phase change. Summary of the Invention

[0006] This invention provides a high-purity silica high-temperature phase change furnace to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

Two second air guide pipes are fixedly connected to the output end of the second air distribution plate. The outer walls of the two second air guide pipes penetrate and slide through the inner cavity of the cover and the material distribution chamber, and a pressure boosting plate is inserted into the end of each of the two second air guide pipes.

[0011] A further improvement of the technical solution of the present invention is that: a screening chamber is fixedly connected to the top of one side of the inner wall of the material distribution chamber, and both ends of the inner wall of the screening chamber are fixedly connected to one side of the outer wall of the two pressure plates. A temporary storage chamber is provided at the bottom of the inner wall of the screening chamber. Two symmetrical cavities are provided between the screening chamber and the temporary storage chamber. Several symmetrical discharge ports are provided at the upper and lower ends of the inner wall of the cavity. A blocking block is slidably connected to the inner wall of the cavity, and a screw is threadedly connected to one end of the inner cavity of the blocking block. The end of the screw passes through and is rotatably connected to one side of the inner wall of the cavity.

[0012] A further improvement of the technical solution of the present invention is that: the inner wall of the material distribution bin is provided with a discharge port on the side of the temporary storage bin, and a sealing block is slidably connected to the inner wall of the discharge port.

[0013] A further improvement of the technical solution of the present invention is that: the inner cavity of the material distribution bin is provided with two mutually symmetrical second insertion holes between the first air guide pipe and the second air guide pipe, and the inner wall of each second insertion hole is rotatably connected with a nut, and the end of the nut is fixedly connected to the end of the lead screw.

[0014] A further improvement of the technical solution of the present invention is that: one side of the outer wall of the second air distribution plate is connected to the outer wall of the cover by bolt thread, and the outer wall of the cover is provided with two mutually stacked guide holes between the first air distribution plate and the second air distribution plate.

[0015] A further improvement of the technical solution of the present invention is that: an electric telescopic rod is fixedly connected to the outer wall of the phase change body near the center of the air pump, and the outer wall of the output end of the electric telescopic rod penetrates and slides through the outer wall of the phase change body, while the output end of the electric telescopic rod is fixedly connected to the outer wall of the material distribution bin.

[0016] A further improvement of the technical solution of the present invention is that: a motor is fixedly connected to one end of the outer wall of the phase change body, and a transmission gear rod is fixedly connected to the output end of the motor.

[0018] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0019] 1. This invention provides a high-purity silica high-temperature phase change furnace. By activating the gas storage chamber, the heated inert gas in the gas storage chamber is discharged into the first insertion hole through the first gas delivery pipe and the first gas distribution plate. Since an exhaust plate is provided at the end of the inner wall of the first insertion hole away from the first gas delivery pipe, and the exhaust plate is located in the silica material, when the inert gas enters from the input end of the exhaust plate, it is evenly discharged into the silica material through its output end. Under the impetus of the inert gas flow, the silica material becomes loose. At the same time, the temperature of the inert gas heats the inside of the silica material. In addition, the mullite fiber tube and the partition drive the silica material to shift internally. This not only satisfies the problem of uniform heating inside the silica material, but also makes the silica material loose. This further solves the problem that in the traditional high-purity silica high-temperature phase change furnace, the silica material requires a stable environment for atomic rearrangement, which causes the drum to rotate at a very low speed, making it difficult to achieve uniform heating of the silica material.

[0020] 2. This invention provides a high-purity silica high-temperature phase change furnace. By providing discharge ports at both ends of the inner wall of the screening chamber, the phase change silica material in the screening chamber moves along the discharge ports into a temporary storage chamber for storage. Subsequently, the operator rotates the control lever in the opposite direction, causing the nut to pass through the screw, resetting the blockage and sealing the discharge ports. The remaining silica material in the distribution chamber then continues to undergo phase change treatment. This further solves the problem that traditional high-purity silica high-temperature phase change furnaces typically use granular silica for phase change treatment to facilitate subsequent processing. However, when performing high-temperature phase change on granular materials, it is difficult to maintain sufficient gaps between the materials, leading to increased temperature within the particle pile and causing silica phase change failure.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 11As shown in the embodiment of the present invention, a high-purity silica high-temperature phase change furnace includes a phase change body 1 and a gas storage chamber 2. An extension plate 3 is fixedly connected to one side of the outer wall of the phase change body 1, and an electric telescopic platform 4 is fixedly connected to the end of the extension plate 3. A cover 5 is rotatably connected to the output end of the electric telescopic platform 4, and one side of the outer wall of the cover 5 is in contact with the outer wall of the phase change body 1. An air pump 6 is fixedly connected to the end of the outer wall of the phase change body 1 away from the cover 5, and an exhaust pipe 7 is fixedly connected to the input end of the air pump 6. The end of the exhaust pipe 7 penetrates and is fixedly connected to the outer wall of the phase change body 1. An aluminum silicate cotton tube 8 is fixedly connected to the inner wall of the phase change body 1, and an electric heating ring 9 is fixedly connected to one end of the inner wall of the phase change body 1 near the aluminum silicate cotton tube 8. A mullite fiber tube 10 is rotatably connected to one end of the inner wall of the phase change body 1 near the electric heating ring 9, and an auxiliary component is provided on the inner wall of the mullite fiber tube 10. The auxiliary component includes a material distribution bin 11 slidably connected to the inner wall of the phase change body 1, and several partitions 12 are fixedly connected to the inner wall of the material distribution bin 11. An exhaust plate 13 is fixedly connected to one end of the inner wall of the material distribution bin 11 near the partitions 12. Several mutually symmetrical first inserts are opened at one end of the inner cavity of the material distribution bin 11. Hole 14, and one end of the inner wall of the first insertion hole 14 is fixedly connected to the input end of the exhaust plate 13. A plurality of first air guide tubes 15 are inserted into the end of the inner wall of the first insertion hole 14 away from the exhaust plate 13. The outer wall of the first air guide tube 15 penetrates and slides through the inner cavity of the cover 5. The end of the first air guide tube 15 is fixedly connected to the first air distribution plate 16. The input end of the first air distribution plate 16 is fixedly connected to the first air delivery tube 17. The end of the first air delivery tube 17 is fixedly connected to the output end of the air storage chamber 2. An electric telescopic rod 34 is fixedly connected to the outer wall of the phase change body 1 near the center of the air pump 6. The outer wall of the output end of the telescopic rod 34 penetrates and is slidably connected to the outer wall of the phase change body 1, while the output end of the electric telescopic rod 34 is fixedly connected to the outer wall of the material distribution bin 11. One end of the outer wall of the phase change body 1 is fixedly connected to a motor 35, and the output end of the motor 35 is fixedly connected to a transmission gear rod 36. The outer wall of the transmission gear rod 36 penetrates and is rotatably connected to the inner cavity of the phase change body 1. The outer wall of the transmission gear rod 36 is meshed with a gear ring 37, and the inner wall of the gear ring 37 is rotatably connected to the inner wall of the phase change body 1. One side of the inner wall of the gear ring 37 is fixedly connected to one side of the outer wall of the mullite fiber tube 10.

[0035] During operation, an extension plate 3 is installed on one side of the outer wall of the phase change body 1, and an electric telescopic platform 4 is installed at the end of the extension plate 3. The electric telescopic platform 4 is activated, and the cover 5 at its output end is disengaged from the phase change body 1. Then, the cover 5 is rotated. Since the inner wall of the phase change body 1 is provided with an aluminum silicate cotton tube 8, and an electric heating ring 9 is provided at one end of the inner wall of the phase change body 1 near the aluminum silicate cotton tube 8, and a mullite fiber tube 10 is provided at one end of the inner wall of the phase change body 1 near the electric heating ring 9, and a material distribution bin 11 is provided inside the mullite fiber tube 10 (here, the material distribution bin 11 and the partition 12, exhaust plate 13, screening bin 22, pressure plate 21, screening bin 22, sealing block 30, blocking block 27, screw 28 and nut 32 inside are all made of graphite), thus The silica material is poured into the distribution bin 11, filling it to two-thirds full. Then, the cover 5 is closed, and the electric telescopic table 4 is restarted, causing the cover 5 to fit tightly against the outer wall of the phase change body 1 (the contact surface between the cover 5 and the phase change body 1 is sealed). At this time, the air pump 6, located at the end of the outer wall of the phase change body 1 away from the cover 5, is started, and the air extraction pipe 7 at its output end penetrates the outer wall of the phase change body 1 (the air extraction pipe 7 is sealed between the air extraction pipe 7 and the phase change body 1), extracting the air from the phase change body 1 and creating a vacuum environment inside the phase change body 1. Then, the electric heating ring 9 is started to heat the mullite fiber tube 10, thereby performing phase change treatment on the silica material in the distribution bin 11.

[0036] It should be further explained that, in order to ensure uniform heating of the silica material, a gear ring 37 (made of graphite) is installed on one side of the outer wall of the mullite fiber tube 10. The motor 35, located at one end of the outer wall of the phase change body 1, is activated. This motor 35 drives the transmission gear rod 36 (composed of a gear and a connecting rod, with the outer wall of the connecting rod penetrating the outer wall of the phase change body 1 and the penetration point sealed, which is existing technology) at its output end to rotate. This, in turn, causes the transmission gear rod 36 to drive the mullite fiber tube 10 to rotate via the gear ring 37, and the mullite fiber tube 10 then... The silica material in the distribution bin 11 is turned over. Since silica needs to be in a stable environment during phase change treatment, the mullite fiber tube 10 rotates once every half hour. In conjunction with several baffles 12 set on the inner wall of the distribution bin 11, the silica material in the distribution bin 11 is turned over. Since the baffles 12 have a smooth arc, as the mullite fiber tube 10 rotates, the silica material in the distribution bin 11 is shifted along the smooth surface of the baffles 12, thereby shifting the silica material to the inner wall and achieving the purpose of uniform heating of the silica material.

[0037] It should be further explained that by setting a first gas delivery pipe 17 at the output end of the gas storage chamber 2 (which consists of a gas storage tank and a gas heating device, belonging to the prior art), and setting a first gas distribution plate 16 at the end of the first gas delivery pipe 17, since a limiting groove 38 is set at one end of the outer wall of the cover 5, and guide blocks 39 are set at both ends of the bottom of the inner wall of the limiting groove 38, the bottom of the first gas distribution plate 16 is aligned with the guide blocks 39, and the first gas distribution plate 16 is pushed into the inner wall of the limiting groove 38. This allows several first gas guide pipes 15 set at the output end of the first gas distribution plate 16 to pass through the cover 5 and be inserted into several first insertion holes 14 symmetrically arranged at one end of the inner cavity of the distribution chamber 11 (the outer wall of the first gas guide pipe 15 and the inner wall of the first insertion hole 14 are sealed). At this time, the gas storage chamber 2 is activated, and the heated inert gas (here, the inert gas is nitrogen) in the gas storage chamber 2 flows along the first gas delivery pipe 17 and the first gas distribution plate 16. The gas is discharged from the first gas pipe 15 into the first insertion hole 14. Since the end of the inner wall of the first insertion hole 14 away from the first gas pipe 15 is provided with an exhaust plate 13, and the exhaust plate 13 is in the silica material at this time, when the inert gas enters from the input end of the exhaust plate 13, it is evenly discharged into the silica material along with its output end. Under the push of the inert gas flow, the silica material becomes loose. At the same time, the temperature of the inert gas is used to heat the inside of the silica material. In addition, the mullite fiber tube 10 and the partition 12 drive the silica material to shift inside. This not only satisfies the problem of uniform heating inside the silica material, but also makes the silica material loose. This further solves the problem that in the traditional high-purity silica high-temperature phase change furnace, the silica material needs a stable environment for atomic rearrangement, which causes the drum to rotate at a very low speed, making it difficult to achieve uniform heating of the silica material.

[0038] It should be further explained that after the phase change of the silica material is completed, the heating ring 9 and the motor 35 are turned off. After the temperature inside the phase change body 1 is close to the outside temperature, the air pump 6 is started to extract the inert gas inside the phase change body 1 through the air extraction pipe 7, so that a vacuum environment is formed inside the phase change body 1. Then, the electric telescopic table 4 is started to make the cover 5 separate from the phase change body 1, and outside air rushes in through the gap between the cover 5 and the phase change body 1. Then, the cover 5 is folded over, and the electric telescopic rod 34 set on the outer wall of the phase change body 1 near the center of the air pump 6 is started, so that its output end passes through the outer wall of the phase change body 1 (the outer wall of the output end of the electric telescopic rod 34 and the outer wall of the phase change body 1 are sealed). This pushes the distribution bin 11 out of the phase change body 1. At this time, the phase change silica material in the distribution bin 11 is discharged through the gap between the distribution bin 11 and the phase change body 1.

[0039] A second air supply pipe 18 is fixedly connected to the outer wall of the gas storage chamber 2 near the output end of the first air supply pipe 17. A second air distribution plate 19 is fixedly connected to the end of the second air supply pipe 18. Two second air guide pipes 20 are fixedly connected to the output end of the second air distribution plate 19. The outer walls of the two second air guide pipes 20 penetrate and slide through the inner cavity of the cover 5 and the distribution chamber 11. A booster plate 21 is inserted into the end of each of the two second air guide pipes 20. A pressure plate 21 is fixedly connected to the top of one side of the inner wall of the distribution chamber 11. The system includes a screening chamber 22, with both ends of its inner wall fixedly connected to one side of the outer wall of two booster plates 21. A temporary storage chamber 24 is located at the bottom of the inner wall of the screening chamber 22. Two symmetrical cavities 25 are formed between the screening chamber 22 and the temporary storage chamber 24. Several symmetrical discharge ports 23 are located at the upper and lower ends of the inner wall of each cavity 25. A blocking block 27 is slidably connected to the inner wall of each cavity 25, and a lead screw 28 is threadedly connected to one end of the inner cavity of the blocking block 27. The end of the lead screw 28... The part penetrates and is rotatably connected to one side of the inner wall of the cavity 25. The inner wall of the distribution bin 11 has a discharge port 29 on one side of the temporary storage bin 24, and a sealing block 30 is slidably connected to the inner wall of the discharge port 29. The inner cavity of the distribution bin 11 has two symmetrical second insertion holes 31 between the first air guide pipe 15 and the second air guide pipe 20, and the inner wall of each second insertion hole 31 is rotatably connected to a nut 32. The end of the nut 32 is fixedly connected to the end of the screw 28. The second air distribution plate One side of the outer wall of 19 is connected to the outer wall of the cover 5 by bolt thread, and the outer wall of the cover 5 is provided with two mutually stacked guide holes 33 between the first air distribution plate 16 and the second air distribution plate 19. One end of the outer wall of the cover 5 is provided with a limiting groove 38, and the inner wall of the limiting groove 38 is slidably connected to the outer wall of the first air distribution plate 16. Both ends of the bottom of the inner wall of the limiting groove 38 are fixedly connected to guide blocks 39, and the outer wall of the guide blocks 39 is slidably connected to the two ends of the bottom of the first air distribution plate 16.

[0040] During operation, a second air supply pipe 18 is installed on the outer wall of the gas storage chamber 2 near the output end of the first air supply pipe 17, and a second air distribution plate 19 is installed at the end of the second air supply pipe 18. The second air distribution plate 19 is fixed to the surface of the cover 5 with bolts, and two mutually symmetrical second air guide pipes 20 installed at the output end of the second air distribution plate 19 pass through the inner cavity of the cover 5 and the distribution chamber 11, and are connected to the input end of the booster plate 21 at their ends. Since a screening chamber 22 is installed at the top of one side of the inner wall of the distribution chamber 11, and the two ends of the inner wall of the screening chamber 22 are connected to one side of the outer wall of the two booster plates 21, when the silica material in the phase change body 1 is heated for one hour... After processing, the speed of motor 35 is increased, causing the transmission gear rod 36 to quickly drive the mullite fiber tube 10 to rotate through the gear ring 37. Under the influence of inertia, the silica in the distribution bin 11 is lifted up, and under the action of gravity, the silica material falls into the screening bin 22. At this time, the gas storage bin 2 is activated, so that high-pressure inert gas enters the booster plate 21 through the second gas delivery pipe 18, the second gas distribution plate 19, and the second gas guide pipe 20. The booster plate 21 sprays out heated inert gas, and the high-pressure inert gas blows towards the silica material falling into the screening bin 22. Due to the phase change of the crystalline silica (e.g., quartz with a density of 2.65 g / cm³), the silica material falls into the screening bin 22. 3 Its density is higher than that of amorphous silica before phase transformation (density approximately 2.2 g / cm³). 3This process causes the silica material that has completed the phase change to accumulate at the bottom of the screening chamber 22, while the silica material that has not completed the phase change is discharged through the discharge port 23 at one end of the inner wall of the screening chamber 22 under the traction of high-pressure inert gas. Since the structures at both ends of the inner wall of the screening chamber 22 are exactly the same, when the mullite fiber tube 10 rotates clockwise ten to twenty times, the motor 35 rotates in the opposite direction, driving the mullite fiber tube 10 to rotate in the opposite direction to screen the silica material on the other side. Then the motor 35 returns to a speed of rotating once every half hour. At this time, the operator holds a special control rod (the control rod is a metal rod with a similar structure installed at the end). A custom screwdriver (a prior art tool) is inserted into two symmetrical guide holes 33 located on the outer wall of the cover 5 between the first air distribution plate 16 and the second air distribution plate 19, so that the end of the control rod extends into two symmetrical second insertion holes 31 located in the inner cavity of the material distribution bin 11 between the first air guide pipe 15 and the second air guide pipe 20. Since a temporary storage bin 24 is located at the bottom of the inner wall of the screening bin 22, and two cavities 25 are located between the screening bin 22 and the temporary storage bin 24, and a screw rod 28 is provided at one end of the inner wall of each cavity 25, a nut 32 is provided on the inner wall of the second insertion hole 31, and the end of the nut 32 is connected to the end of the screw rod 28. When the screwdriver at the end of the control lever is inserted into the nut 32, rotating the control lever causes the nut 32 to drive the lead screw 28 to rotate. Since the lead screw 28 has a blocking block 27 on its outer wall, and the blocking block 27 is located within the cavity 25, the rotation of the lead screw 28 causes the blocking block 27 to move along the inner wall of the cavity 25. Because both ends of the inner wall of the screening chamber 22 have discharge ports 23, the movement of the blocking block 27 (where the outer wall of the blocking block 27 has a slightly larger notch than the discharge port 23; when the notch moves below the discharge port 23, the discharge port 23 and the notch communicate) allows the phase change silica material within the screening chamber 22 to move freely. The material enters the temporary storage bin 24 through the discharge port 23 and is then stored. The operator then rotates the control lever in the opposite direction, causing the nut 32 to pass through the screw 28, which resets the block 27 and seals the discharge port 23. At this time, the remaining silica material in the distribution bin 11 continues to undergo heating and phase change treatment. This further solves the problem that in the traditional high-purity silica high-temperature phase change furnace, granular silica is usually used for phase change treatment to facilitate subsequent processing. However, when performing high-temperature phase change on granular materials, it is difficult to leave enough gaps between the materials, which leads to an increase in temperature inside the material particle pile and causes silica phase change failure.

[0041] It should be further explained that by setting a discharge port 29 on the inner wall of the distribution bin 11 on the side of the temporary storage bin 24, and setting a sealing block 30 on the inner wall of the discharge port 29, after the phase change of the silica material is completed, the phase change silica material in the temporary storage bin 24 can be discharged by pulling out the sealing block 30 in the discharge port 29.

[0042] The working principle of this high-purity silica high-temperature phase change furnace will be explained in detail below.

[0043] like Figures 1 to 11 As shown, an extension plate 3 is provided on one side of the outer wall of the phase change body 1, and an electric telescopic platform 4 is provided at the end of the extension plate 3. The electric telescopic platform 4 is activated, and the cover 5 at its output end is disengaged from the phase change body 1. Then, the cover 5 is rotated. Since the inner wall of the phase change body 1 is provided with an aluminum silicate cotton tube 8, and an electric heating ring 9 is provided at one end of the inner wall of the phase change body 1 near the aluminum silicate cotton tube 8, and a mullite fiber tube 10 is provided at one end of the inner wall of the phase change body 1 near the electric heating ring 9, and a distribution bin 11 is provided inside the mullite fiber tube 10, the silica material is poured into the distribution bin 11, and the silica material is placed at two-thirds of the position in the distribution bin 11. Then, the cover 5 is closed, and the electric telescopic platform is activated again. Platform 4 is used to bring the cover 5 into close contact with the outer wall of the phase change body 1. At this time, the air pump 6, located at the end of the outer wall of the phase change body 1 away from the cover 5, is activated. The air extraction pipe 7 at its output end penetrates the outer wall of the phase change body 1 and extracts the air from the phase change body 1, creating a vacuum environment inside the phase change body 1. Subsequently, the electric heating ring 9 is activated to heat the mullite fiber tube 10, thereby performing phase change treatment on the silica material in the distribution bin 11. A first air supply pipe 17 is installed at the output end of the air storage bin 2, and a first air distribution plate 16 is installed at the end of the first air supply pipe 17. Since a limiting groove 38 is provided at one end of the outer wall of the cover 5, and guides are provided at both ends of the bottom of the inner wall of the limiting groove 38, Block 39, thereby aligning the bottom of the first gas distribution plate 16 with the guide block 39, and pushing the first gas distribution plate 16 into the inner wall of the limiting groove 38, so that the several first gas guide pipes 15 provided at the output end of the first gas distribution plate 16 pass through the cover 5 and are inserted into several first insertion holes 14 symmetrically arranged at one end of the inner cavity of the distribution bin 11. At this time, the gas storage bin 2 is activated, and the heated inert gas in the gas storage bin 2 is discharged from the first gas guide pipe 15 into the first insertion hole 14 along the first gas delivery pipe 17 and the first gas distribution plate 16. Since the end of the inner wall of the first insertion hole 14 away from the first gas guide pipe 15 is provided with an exhaust plate 13, and the exhaust plate 13 is in silica material at this time, so when the inert gas comes out from the exhaust plate After entering through the input end of 13, the silica material is evenly discharged into the output end. Under the impetus of the inert gas flow, the silica material becomes loose. At the same time, the temperature of the inert gas heats the inside of the silica material. In addition, the mullite fiber tube 10 and the partition 12 drive the silica material to shift inside. This not only satisfies the problem of uniform heating inside the silica material, but also makes the silica material loose. This further solves the problem that in the traditional high-purity silica high-temperature phase change furnace, the silica material needs a stable environment for atomic rearrangement, which causes the drum to rotate at a very low speed, making it difficult to achieve uniform heating of the silica material.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
