Description

Technical Field

[0001] The present application relates to the technical field of material processing and treatment, and in particular to a rotary growth device. Background Art

[0002] With the rapid development of glass, people have put forward higher requirements on the functions and performance of glass, and then special glass has appeared in life. Special glass refers to glass with special components doped inside according to actual needs, so as to achieve special functions or meet certain performances, such as glass with light transmission, heat insulation, sound insulation, wear resistance, climate change resistance and other properties, and some also have characteristics such as heat preservation, heat absorption, and radiation protection. Taking microcrystalline glass as an example of special glass, the manufacturing process of microcrystalline glass can also be divided into rolling method, pressing method, float method and casting method.

[0003] For the float process, the forming process of microcrystalline glass is completed in a tin bath with protective gas. Specifically, after the glass materials such as sodium salt and calcium salt are melted, the molten glass materials are passed into the tin bath. The molten glass material flows continuously from the tank kiln and floats on the surface of the relatively dense tin liquid. Under the action of gravity and surface tension, the glass liquid spreads and flattens on the tin liquid surface to form a flat upper and lower surface, hardens, and is then led to the transition roller table after cooling. The rollers of the roller table rotate, pulling the glass ribbon out of the tin bath and into the annealing kiln. After annealing and cutting, the glass product is obtained.

[0004] However, the investment scale of glass in related technologies is large, and the energy consumption is high. Once the production line is started, stopping the line will incur huge losses.

[0032] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0033] It should be noted that the material to be processed in this embodiment includes but is not limited to glass, especially special glass, such as microcrystalline glass; in addition, the material to be processed may also be other materials such as ceramics, crystals, metals, plastics and resins. In this embodiment, the material is specifically microcrystalline glass as an example, but it is not limited to this.

[0034] Referring to Figures 1 to 4, Figures 1 to 4 respectively show four different working state diagrams of a rotary growth device in an embodiment of the present application. A rotary growth device provided in an embodiment of the present application includes: a main furnace chamber 10, a growth tube 20 and a first lifting mechanism 30. The main furnace chamber 10 is provided with a container 11 and a first heating mechanism 12. The container 11 is used to place a material 40 to be processed. The first heating mechanism 12 is used to heat the container 11 so that the material 40 inside the container 11 is melted. The growth tube 20 is located above the main furnace chamber 10. The first lifting mechanism 30 includes a connecting shaft 31. The connecting shaft 31 can be movably arranged inside the growth tube 20. The first lifting mechanism 30 can drive the connecting shaft 31 to move inside the growth tube 20 along the length direction of the growth tube 20, so that the connecting shaft 31 can penetrate into the main furnace chamber 10 from the top of the main furnace chamber 10 and contact the material 40 inside the container 11, and can drive the connecting shaft 31 to return from the main furnace chamber 10 to the inside of the growth tube 20. The first lifting mechanism 30 can also drive the connecting shaft 31 to rotate around its central axis.

[0035] In some embodiments, the growth tube 20 may be made of, but is not limited to, quartz, graphite, corundum (Al 2 O 3 ), fused bricks (also known as fused zirconium corundum bricks, abbreviated as AZS in English), platinum and glassy carbon, any one or combination thereof.

[0036] Optionally, a release agent is provided on the inner wall of the growth tube 20. The release agent includes boron carbide or graphite coating, etc. In this way, the formed product can be easily separated from the production tube to prevent mutual adhesion.

[0037] When the above rotary growth device is in use, the material 40 is placed inside the container 11, and the first heating mechanism 12 heats the container 11 to melt the material 40 inside the container 11. Then, the first lifting mechanism 30 drives the connecting shaft 31 to move along the length direction of the growth tube 20 and enter the inside of the container 11. After the connecting shaft 31 contacts the molten material 40 inside the container 11, the first lifting mechanism 30 drives the connecting shaft 31 to move upward and drives the connecting shaft 31 to rotate. The rotating connecting shaft 31 can facilitate the molten material 40 to gradually leave the container 11 and enter the inside of the growth tube 20. The molten material 40 is not prone to fracture defects during the process of being pulled by the rotating connecting shaft 31. In addition, when the rotating material 40 moves along the length direction of the growth tube 20, it can prevent the material 40 from sticking to the inner wall of the growth tube 20, so that it is easier to enter the inside of the growth tube 20. The molten material 40 leaving the container 11 can be cooled to obtain the desired product. In this way, the volume of the container 11 can be flexibly adjusted and controlled according to actual needs. When the volume of the container 11 is reduced, it is suitable for the production of small batches of materials, with low energy consumption and low production costs. The recipe can be switched and intermittent production can be carried out according to actual needs, thereby being able to meet the production of multiple and small quantities of products.

[0038] It should be noted that, when the connecting shaft 31 drives the molten material 40 to enter the interior of the growth tube 20, for example, it enters the interior of the growth tube 20 at a uniform speed, so that the material 40 pulled up by the connecting shaft 31 runs more smoothly and will not have a break defect due to the rapid increase in speed during the rise. Optionally, the movement speed of the connecting shaft 31 along the length direction of the growth tube 20 includes but is not limited to 0.01m / S to 0.1m / S, for example, 0.01m / S, 0.05m / S, 0.06m / S, 0.07m / S or 0.1m / S, etc., which can be flexibly adjusted and set according to actual needs and are not limited here. Among them, when the movement speed of the connecting shaft 31 along the length direction of the growth tube 20 is greater than 0.1m / S, it is easy to cause the material 40 to break during the process of pulling up the material 40; when the movement speed of the connecting shaft 31 along the length direction of the growth tube 20 is less than 0.01m / S, the production efficiency is low.

[0039] The first heating mechanism 12 may include but is not limited to an electric heating rod, an electric heating plate, an electric heating sheet, a resistance wire, a burner, electromagnetic heating, infrared heating or chemical reaction heating, etc., and may be flexibly selected according to actual needs, as long as the container 11 can be heated to increase the temperature of the container 11.

[0040] The first heating mechanism 12 can be located on any side of the container 11 and abut against the outer wall of the container 11 to transfer heat to the container 11; or it can be arranged circumferentially around the container 11 and abut against the outer wall of the container 11 to transfer heat to the container 11, or there is an air gap between the first heating mechanism 12 and the outer wall of the container 11, and heat is transferred to the container 11 by means of thermal radiation, so that the container 11 is heated to a preset temperature.

[0041] Specifically, the first heating mechanism 12 can melt the glass-ceramics inside the container 11 into a liquid state to achieve the homogenization of glass-ceramics melting. After the glass-ceramics are melted into a liquid state, for example, the first heating mechanism 12 is controlled to reduce the working power, so that the temperature of the container 11 is reduced, thereby preliminarily cooling the liquid glass-ceramics, which is beneficial to subsequent discharge into the growth tube 20 outside the main furnace chamber 10 for secondary cooling and forming.

[0042] After the molten material 40 is discharged outward through the growth tube 20, it can be gradually cooled and formed at room temperature; or a first cooling mechanism 50 is configured, and under the cooling action of the first cooling mechanism 50, the molten material 40 can be quickly cooled and formed, thereby improving the production efficiency.

[0043] Please refer to FIG. 1. In some embodiments, when the rotary growth device is placed in a normal posture, the growth tube 20 is inclined relative to the horizontal plane. In this way, when the first lifting mechanism 30 drives the connecting shaft 31 to move in the growth tube 20 along the length direction of the growth tube 20, the connecting shaft 31 drives the molten material 40 to enter the inclined growth tube 20. The inclined growth tube 20 plays a supporting role for the material 40. Compared with arranging the growth tube 20 in the vertical direction, it is more convenient to smoothly pull the molten material 40 into the interior of the growth tube 20.

[0044] Please refer to FIG. 1. In some embodiments, the inclination angle of the growth tube 20 relative to the horizontal plane is a, where 0 < a ≤ 80°. Specifically, a includes but is not limited to 5°, 10°, 15°, 20°, 25°, 30°, 45°, 50°, 60°, 75° or 80°.

[0045] In some embodiments, the connecting shaft 31 is configured as a retractable shaft, and the first lifting mechanism 30 can extend or shorten the connecting shaft 31. Specifically, the first lifting mechanism 30 includes a cylinder. When the cylinder drives the connecting shaft 31 to extend, the connecting shaft 31 extends accordingly, and the connecting shaft 31 can extend from the outside of the growth tube 20 and enter the inside of the container 11 to contact the molten material 40 inside the container 11; when the cylinder drives the connecting shaft 31 to retract, the connecting shaft 31 shortens accordingly, and the connecting shaft 31 can return to the inside of the growth tube 20 after shortening, and drive the molten material 40 to move upward along the growth tube 20 and gradually enter the inside of the growth tube 20. Since the connecting shaft 31 is configured in a retractable manner, the overall space occupied by the connecting shaft 31 after retraction can be made smaller.

[0046] On the basis of the above-mentioned embodiment, the first lifting mechanism 30 further includes a first motor, which is connected to the cylinder. The first motor can drive the cylinder to rotate, thereby driving the connecting shaft 31 to rotate.

[0047] In some embodiments, the connecting shaft 31 is not limited to being set as a retractable shaft, for example, it can also be set as a non-retractable shaft. The first lifting mechanism 30 can adjust the position of the connecting shaft 31 along the length direction of the growth tube 20. Specifically, the first lifting mechanism 30 can make the connecting shaft 31 move toward the inside of the container 11, thereby correspondingly driving the connecting shaft 31 to enter the inside of the container 11 and contact the molten material 40; after the connecting shaft 31 is wrapped by the material 40, the first lifting mechanism 30 can also make the connecting shaft 31 pull up the material 40 and return to the inside of the growth tube 20.

[0048] Optionally, the first lifting mechanism 30 includes but is not limited to a gear rack mechanism, a motor screw mechanism, a cylinder mechanism or a cam mechanism, etc., as long as it can realize the lifting and lowering movement of the connecting shaft 31. In addition, in order to realize the rotation of the connecting shaft 31, the first lifting mechanism 30 is integrated with a second motor, and the second motor drives the connecting shaft 31 to rotate.

[0049] In one embodiment, the growth device further includes a first cooling mechanism 50 . The first cooling mechanism 50 is disposed outside the main furnace chamber 10 , and is used to cool the growth tube 20 extending outside the main furnace chamber 10 .

[0050] Optionally, the first cooling mechanism 50 may adopt air cooling, such as using a fan to blow air toward the growth tube 20 to lower the temperature of the growth tube 20; or may adopt physical contact cooling, such as using a circulating water cooling tube or a semiconductor refrigeration component to contact the outer wall of the growth tube 20, thereby lowering the temperature of the growth tube 20.

[0051] When the material 40 is microcrystalline glass, the first cooling mechanism 50 cools the growth tube 20 while the molten material 40 is discharged outward through the growth tube 20 , so that the material 40 can gradually change from liquid to solid, thereby forming a glass product, which is a rod 41 .

[0052] The rod body 41 is adapted to the pipe shape of the growth tube 20, and the shape of the growth tube 20 can be adjusted and set accordingly according to the shape of the required glass product. For example, when the pipe cross-section shape of the growth tube 20 is circular, the rod body 41 formed by the growth tube 20 is a cylindrical rod; when the pipe cross-section shape of the growth tube 20 is rectangular, the glass product formed by the growth tube 20 is a rectangular rod 41. The pipe cross-section shape of the growth tube 20 can also be set to other shapes, which are not limited here.

[0053] It should be noted that after the glass product is formed into a desired shape through the growth tube 20 , various post-processing such as grinding, engraving, printing, etc. may be performed on the glass product to obtain the desired glass product.

[0054] In some embodiments, the main furnace chamber 10 is further provided with a second cooling mechanism 13. The second cooling mechanism 13 is used to cool the container 11 and the material inside the main furnace chamber 10. Thus, under the cooling effect of the second cooling mechanism 13, the functions of heating, melting, homogenizing, clarifying and initial cooling of the glass can be achieved in the main furnace chamber 10.

[0055] In one embodiment, the growth device further includes a second heating mechanism 60. The second heating mechanism 60 is disposed outside the main furnace chamber 10, and the second heating mechanism 60 is used to heat the growth tube 20. Thus, when the first cooling mechanism 50 cools the growth tube 20 so that the microcrystalline glass is cooled and formed, the second heating mechanism 60 can heat the growth tube 20 so that the microcrystalline glass can be nucleated and crystallized. Then, the first cooling mechanism 50 can be used to cool the growth tube 20 to obtain the desired glass product.

[0056] After a large number of experiments and studies, it was found that after the second heating mechanism 60 is used to heat the growth tube 20, the temperature of the microcrystalline glass after the first cooling and forming is increased, and the hardness of the glass product obtained by the second cooling and forming is greatly improved.

[0057] It should be noted that in the heating process of the microcrystalline glass after primary cooling and forming, the specific temperature rise and heating time of the microcrystalline glass can be flexibly adjusted and set according to the needs of the specific glass type, as long as nucleation and crystallization are satisfied, and no specific limitation is made here.

[0058] On the basis of the foregoing embodiments, in order to make the working principle of the rotary growth device in this embodiment for growing microcrystalline glass clearer, the relationship between the temperature of the microcrystalline glass of one embodiment shown in FIG. 1 and the temperature change over time of the microcrystalline glass of one embodiment shown in FIG. 5 is specifically described:

[0059] In the stage from 0 to t1, the glass-ceramics is placed inside the container 11, and the first heating mechanism 12 heats the container 11, so that the temperature of the glass-ceramics inside the container 11 increases and gradually melts, thereby achieving melting and homogenization of the glass-ceramics;

[0060] In the stage from t1 to t2, for example, the first heating mechanism 12 is controlled to reduce the working power, specifically the first heating mechanism 12 is turned off, and in addition, the second cooling mechanism 13 is turned on to reduce the temperature of the container 11, so that the temperature of the microcrystalline glass inside the container 11 is reduced, and the liquid microcrystalline glass is initially cooled;

[0061] Time t2 corresponds to the time when the liquid microcrystalline glass is discharged outward through the growth tube 20.

[0062] During the period from t2 to t3, the first cooling mechanism 50 cools the growth tube 20, so that the material 40 gradually changes from a liquid state to a solid state, and the glass-ceramics is cooled and formed in one step;

[0063] In the stage from t3 to t4, the growth tube 20 is heated by the second heating mechanism 60 to form a nucleus of the glass-ceramics;

[0064] From stage t4 to t5, the temperature of the glass-ceramic is maintained constant to allow the glass-ceramic to crystallize;

[0065] After t5, the growth tube 20 is cooled by the first cooling mechanism 50 to obtain the desired glass product.

[0066] It can be seen that the rotary growth equipment in this embodiment can complete all the steps of melting, clarifying, homogenizing, forming, nucleating and crystallizing special glass, especially microcrystalline glass, and the equipment occupies a small area.

[0067] The volume of the container 11 in this embodiment can be flexibly adjusted and set according to actual needs. The volume of the container 11 satisfies the weight of the installed materials, including but not limited to 0.5Kg, 1Kg, 5Kg, 10Kg, 50Kg, 100Kg, 200Kg, 500Kg or 1000Kg, etc. When a small-volume container 11 is selected, for example, the weight of the material that can be installed in the container 11 is less than or equal to 100Kg, or even less than or equal to 10Kg, or even about 1Kg, it is suitable for the production of small batches of materials, with low energy consumption and low production cost. It can switch recipes and perform intermittent production according to actual needs, thereby realizing the production of multiple, small quantities and low-cost special glasses.

[0068] In some embodiments, the container 11 is a crucible. The crucible includes but is not limited to a quartz crucible, a corundum crucible, a 2 O 3 ), fused bricks (also known as fused zirconium corundum bricks, abbreviated as AZS in English), molybdenum, tungsten, platinum, glassy carbon and refractory clay crucibles, etc., any one or more combinations thereof.

[0069] Specifically, the crucibles in this embodiment are, for example, two and nested with each other. The crucible located on the outside is, for example, a carbon-carbon crucible 111, which plays a heat conductive role and transfers heat to the crucible located inside it. It has a long service life and does not need to be replaced frequently. The crucible located inside is a growth crucible 112, which is used to hold the material 40 to be processed, and directly transfers heat to the material 40 to melt the material 40, and needs to be replaced frequently.

[0070] In one embodiment, the rotary growth equipment further includes an auxiliary furnace chamber 70. The auxiliary furnace chamber 70 is openably connected to the top of the main furnace chamber 10. The first lifting mechanism 30 is installed on the auxiliary furnace chamber 70. The growth tube 20 is installed inside the auxiliary furnace chamber 70. Optionally, the first cooling mechanism 50 is arranged inside the auxiliary furnace chamber 70, and the second heating mechanism 60 is arranged inside the auxiliary furnace chamber 70. In this way, the auxiliary furnace chamber 70 protects the growth tube 20, the first cooling mechanism 50 and the second heating mechanism 60, and provides an environment for the molding of the product, which is conducive to improving the processing quality of the product. In addition, when the material 40 inside the growth tube 20 is cooled to obtain a molded product, the auxiliary furnace chamber 70 can be opened, and then the molded product in the growth tube 20 can be demolded. In addition, the overall volume size of the rotary growth equipment is small, and the equipment occupies a small area.

[0071] In one embodiment, the growth tube 20 is rotatably mounted on the auxiliary furnace chamber 70. The rotary growth device further includes a rotating mechanism, which is mounted on the auxiliary furnace chamber 70. The rotating mechanism is connected to the growth tube 20, and the rotating mechanism is used to drive the growth tube 20 to rotate. In this way, the growth tube 20 is provided with a rotating function, which can prevent the material 40 inside the growth tube 20 from adhering to the inner wall of the growth tube 20, thereby facilitating the demolding of the material 40.

[0072] Optionally, a first through hole is provided at the top of the main furnace chamber 10, and a second through hole is provided at the bottom of the auxiliary furnace chamber 70. The second through hole is arranged corresponding to the position of the first through hole, so that the connecting shaft 31 and the clamping jaw 91 can pass through the second through hole and the first through hole to enter the interior of the main furnace chamber 10, and the molten material 40 in the container 11 can be pulled upward and pass through the first through hole and the second through hole in sequence to enter the interior of the main furnace chamber 10.

[0073] In one embodiment, the growth tube 20 is installed in the main furnace chamber 10 and the auxiliary furnace chamber 70 in a lifting and movable manner. The rotary growth device also includes a second lifting mechanism, which is installed on the auxiliary furnace chamber 70 and connected to the growth tube 20. The second lifting mechanism is used to drive the growth tube 20 to move up and down, and can drive the growth tube 20 to pass from the top of the main furnace chamber 10 into the interior of the main furnace chamber 10, and can drive the growth tube 20 from the main furnace chamber 10 back to the interior of the auxiliary furnace chamber 70. In this way, before the step of heating and melting the material 40 inside the container 11, the growth tube 20 is specifically located inside the auxiliary furnace chamber 70; when the material 40 inside the container 11 is heated, melted and homogenized, the second lifting mechanism drives the growth tube 20 to descend to the inside of the main furnace chamber 10, and the bottom end of the growth tube 20 enters into the inside of the container 11, and driven by the connecting shaft 31, the molten material 40 can gradually enter into the inside of the growth tube 20 through the bottom; when the material 40 is pulled into the inside of the growth tube 20 for a certain length, specifically for example, when it reaches the top, that is, the material 40 fills the entire growth tube 20, the second lifting mechanism drives the growth tube 20 to rise and enter into the inside of the auxiliary furnace chamber 70, leaving the melt inside the container 11, and at the same time, the first lifting mechanism 30 synchronously drives the material 40 inside the growth tube 20 to enter into the inside of the auxiliary furnace chamber 70, so that the growth tube 20 and the material 40 inside it are both located inside the auxiliary furnace chamber 70, which can achieve a better cooling and molding effect inside the auxiliary furnace chamber 70.

[0074] In some embodiments, the growth tube 20 is provided with a rotation function, which can prevent the material 40 inside the growth tube 20 from adhering to the inner wall of the growth tube 20, thereby facilitating demolding of the material 40. Specifically, the second lifting mechanism can not only drive the growth tube 20 to move up and down, but also drive the growth tube 20 to rotate around its central axis, thereby realizing the rotation function of the growth tube 20.

[0075] In some embodiments, the second lifting mechanism includes, but is not limited to, a gear rack mechanism, a motor screw mechanism, a cylinder mechanism, or a cam mechanism, etc., as long as it can achieve the lifting and lowering movement of the growth tube 20. In addition, in order to achieve the rotation of the growth tube 20, the second lifting mechanism is integrated with a rotating motor, and the rotation of the growth tube 20 is achieved under the drive of the rotating motor.

[0076] In one embodiment, the rotary growth device further includes a shearing mechanism 80. The shearing mechanism 80 is, for example, disposed at the bottom of the auxiliary furnace chamber 70. The shearing mechanism 80 can shear the material 40 at the bottom end of the growth tube 20.

[0077] Optionally, the shearing mechanism 80 includes but is not limited to scissors, a cutting blade or a cutting board, etc.

[0078] When the rod body 41 has a certain length in the growth tube 20, the specific length of the rod body 41 can be set according to actual needs. The bottom end of the rod body 41 is sheared by the shearing mechanism 80. The rod body 41 after shearing is stored in the auxiliary furnace chamber 70 for post-processing.

[0079] Specifically, during the growth process, the material 40 is cooled and formed inside the growth tube 20 to obtain a rod body 41. The top end of the rod body 41 enters the auxiliary furnace chamber 70 before the bottom end of the rod body 41. The top end of the rod body 41 is cooled first and has a higher hardness. The bottom end of the rod body 41 enters the auxiliary furnace chamber 70 later and has a lower hardness. After the bottom end of the rod body 41 is separated from the material 40 inside the container 11, there is a spike 42.

[0080] Please refer to FIG4 , the bottom end of the rod body 41 is sheared in time by the shearing mechanism 80, so that the bottom end surface is more flat and beautiful. In addition, the bottom end of the rod body 41 is not fully cooled because it is separated from the container 11, and the hardness is relatively low, so it is easy to cut off and easy to operate. In addition, the cut spikes 42 can be returned to the container 11 for reuse.

[0081] On the contrary, if the bottom end of the rod body 41 is not sheared by the shearing mechanism 80, the rod body 41 with the spikes 42 flows into the post-processing step for processing. In the post-processing step, the spikes 42 are usually directly broken off or cut. Since the spikes 42 are cooled and have a high hardness, the rod body 41 is easily broken during the post-processing process, which reduces the product quality.

[0082] Please refer to Figures 2 and 3. In one embodiment, the rotary growth device also includes a clamp 91 that is movably disposed inside the growth tube 20. The clamp 91 is connected to the connecting shaft 31, and the connecting shaft 31 can drive the clamp 91 to move inside the growth tube 20 along the length direction of the growth tube 20, and can drive the clamp 91 to rotate inside the growth tube 20. In this way, when the clamp 91 extends into the melt inside the container 11 and is wrapped by the melt, the contact area between the clamp 91 and the melt is large, and the adhesion force is large, so that the melt can be easily pulled up and driven into the interior of the growth tube 20. In addition, the clamp 91 clamps the top of the material 40, which can also facilitate the material 40 to gradually enter the interior of the growth tube 20 along the length direction of the growth tube 20.

[0083] The chemical reaction during glass melting will release a large amount of gas, such as CO 2 , H 2 O、NO 2 and SO 2 Based on this, a vacuum mechanism is provided on the main furnace chamber 10. The vacuum mechanism is used to exhaust and treat the waste gas generated during the melting process of the material 40. Among them, the vacuum mechanism specifically adopts a large-displacement vacuum mechanism. During the glass melting process, the main furnace chamber 10 is exhausted with a large amount of air through the vacuum mechanism, so as to effectively remove the waste gas generated by the melting.

[0084] In some embodiments, the main furnace chamber 10 is provided with a feeding port. The feeding port is used to connect with a material preparation mechanism that can provide material 40. Among them, the feeding port can be set as a continuous feeding port, for example, and the continuous feeding port is used to continuously receive the material 40 provided by the material preparation mechanism. The material 40 is fed into the interior of the container 11 through the feeding port, melted under the heating treatment of the container 11, and continuously discharged outward through the growth tube 20. Optionally, a switch valve is provided at the feeding port. When the material 40 inside the container 11 is insufficient, the switch valve is opened, and the material is fed into the container 11 through the feeding port; when the material 40 inside the container 11 reaches a preset amount, the switch valve is closed to ensure that the main furnace chamber 10 is in a closed state, thereby preventing the gas of the external environment from entering the main furnace chamber 10 and causing an adverse effect on the melting of the material 40 inside the main furnace chamber 10. In addition, since the material 40 can be continuously replenished into the main furnace chamber 10 through the feeding port, it is ensured that the material 40 inside the container 11 is sufficient. Then the growth tube 20 continuously discharges the material, and a molded product of any length can be obtained. In addition, materials can be added and melted continuously to increase production capacity and crucible service life.

[0085] In some embodiments, a discharge port is provided on the top of the auxiliary furnace chamber 70. The discharge port is opposite to the discharge port of the growth tube 20, and the molded product grown by the growth tube 20 can be directly discharged outward through the discharge port, which can achieve continuous discharge. At the same time, the discharge will not be interfered by the auxiliary furnace chamber 70, so that the length of the molded product can be longer or shorter.

[0086] In some embodiments, a ventilation mechanism is provided on the main furnace chamber 10. The ventilation mechanism is used to add protective gas into the interior of the main furnace chamber 10. Optionally, the protective gas includes but is not limited to an inert gas. The inert gas includes but is not limited to argon or nitrogen, etc. In this way, during the glass drawing process, the main furnace chamber 10 is passed with an inert gas, and the molten liquid inside the container 11 is protected by low-pressure inertness and a pressure difference is provided, which can improve the product quality.

[0087] Specifically, the exhaust mechanism and the ventilation mechanism are combined to form a gas adjustment mechanism 92. The gas adjustment mechanism 92 can not only exhaust the waste gas generated during the melting process of the material 40, but also add protective gas into the interior of the main furnace chamber 10.

[0088] In some embodiments, a heat preservation cover 93 is further provided on the top of the main furnace chamber 10. The heat preservation cover 93 is provided above the container 11 to keep the container warm. Optionally, a third through hole is provided on the heat preservation cover 93. The third through hole is provided corresponding to the position of the connecting shaft 31. In this way, the connecting shaft 31 and the clamping jaw 91 penetrate the heat preservation cover 93 and extend downward into the interior of the container 11. In addition, under the lifting and lowering adjustment of the first lifting mechanism 30, the connecting shaft 31 and the clamping jaw 91 can move up and down relative to the heat preservation cover 93.

[0089] In one embodiment, the rotary growth device further includes a third lifting mechanism 94. The third lifting mechanism 94 is disposed on the main furnace chamber 10, and the third lifting mechanism 94 is connected to the container 11, and the third lifting mechanism 94 is used to drive the container 11 to move up and down. In this way, according to the height position of the bottom end of the connecting shaft 31 or the clamping claw 91, the third lifting mechanism 94 drives the container 11 to move up and down, and can adaptively adjust the height position of the container 11 inside the main furnace chamber 10, so that the material 40 inside the container 11 can contact the bottom end of the connecting shaft 31 or the clamping claw 91, so that it can be pulled up and brought into the interior of the growth tube 20.

[0090] In some embodiments, the third lifting mechanism 94 also has a rotation function, which can drive the container 11 to rotate, thereby making the material 40 inside the container 11 more uniform.

[0091] The specific structure of the third lifting mechanism 94 is similar to that of the first lifting mechanism 30 , and will not be described in detail here.

[0092] In some embodiments, the rotary growth device further includes an optical sensor 95 and a controller. The optical sensor 95, the pressure adjustment mechanism, the rotation mechanism, the first heating mechanism 12, the first lifting mechanism 30, the first cooling mechanism 50, the second heating mechanism 60 and the third lifting mechanism 94 are all electrically connected to the controller. The optical sensor 95 is used to detect the state of the material 40 inside the container 11 and determine whether the material 40 is heated to a molten state. In addition, the optical sensor 95 can also detect the height position of the material 40 inside the container 11. The controller can control the pressure adjustment mechanism, the rotation mechanism, the first heating mechanism 12, the first lifting mechanism 30, the first cooling mechanism 50, the second heating mechanism 60 and the third lifting mechanism 94 to work in coordination according to the state of the material 40 and the height position of the material 40 detected by the optical sensor 95, and the degree of automation is relatively high.

[0093] In the main furnace chamber 10, the functions of heating, melting, homogenizing, clarifying and initial cooling of the microcrystalline glass are realized; then in the auxiliary furnace chamber 70, the material 40 is pulled into the growth tube 20, preliminarily cooled, sheared and tailed, nucleated, microcrystallized and cooled to form are realized.

[0094] According to the thermal conductivity and thermal radiation properties of the glass, the thermal field, heater, furnace cavity space and insulation system of the main furnace chamber 10 are flexibly adjusted and designed to achieve the functions of uniform heating, melting and initial cooling of the glass.
