Description

Technical Field

[0001] The present invention relates to glass production equipment, in particular to a tubular glass furnace device. Background Art

[0002] Glass kilns are high-temperature furnaces used to manufacture glass. They melt raw materials at high temperatures to form molten glass, which is then processed through various processes (such as blowing, pressing, and drawing) into the desired glass products. Existing glass kilns are typically constructed from bricks, cement, steel bars, and other materials, making them suitable for large-scale production. However, the construction costs of glass kilns are very high, often costing tens of millions of yuan.

[0003] Therefore, the existing glass kiln construction method is not suitable for small-batch production, and due to its high cost, only companies with very strong financial resources can build glass kilns for glass production, while other small and medium-sized enterprises cannot build glass kilns for glass production due to limited funds.

[0004] Therefore, if a glass furnace that is suitable for small-batch production and has greatly reduced costs can be provided, it will be able to meet the actual needs of the market. To this end, the applicant has developed a tubular glass furnace. During the research and development process, it was found that since the melting temperature of glass raw materials is between 1400 and 1680 degrees Celsius, the temperature of the corresponding heating body exceeds that of existing metal materials. Among the existing metal materials, it is difficult to find a material that can withstand such high temperatures, is easy to process, and has a reasonable price. Experiments have found that materials that can withstand temperatures above 1400 degrees Celsius are difficult to process, and the accuracy after processing is difficult to grasp. The existing assembly structure has large intervals, and the accuracy is difficult to meet the requirements, which easily leads to leakage. Therefore, the existing tubular kiln structure still needs to be improved to solve the problems of processing accuracy and cost. Summary of the Invention

[0032] The following examples are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0033] like Figures 1 to 3 As shown, the tubular glass furnace device of the present invention includes a base beam 20, a feed pipe 10, and a first discharge pipe 30. The base beam 20 is arranged along a first direction X, and the feed pipe 10 and the first discharge pipe 30 are arranged along a second direction Y. The base beam 20 is transversely connected between the first feed pipe 10 and the first discharge pipe 30, and the base beam 20, the feed pipe 10, and the first discharge pipe 30 are connected to form a glass liquid circulation channel.

[0034] The main point of the present invention is that the feed pipe 10 and the first discharge pipe 30 are directly connected via the base beam 20, thereby forming the main structure of the tubular glass furnace. This main structure is the minimum structure of the tubular glass furnace device. That is, the raw materials for producing molten glass can enter through the feed pipe 10, melt into molten glass within the feed pipe 10, then flow through the base beam 20 to the first discharge pipe 30, and then flow out of the first discharge pipe 30, completing the melting, clarification, and cooling processes of the molten glass production. The tubular glass furnace device of the present invention has a simple structure and is easy to process and assemble, thus facilitating easy production and reducing costs.

[0035] Furthermore, the first direction X and the second direction Y are perpendicular. In this embodiment, the first direction X is horizontal, and the second direction Y is vertical. Thus, when the feed pipe 10 and the first discharge pipe 30 are installed on the base beam 20, external support structures can be greatly reduced, facilitating installation of the feed pipe 10 and the first discharge pipe 30 and saving costs.

[0036] The base beam 20, the feed pipe 10, and the first discharge pipe 30 are all tubular components, and thus are easy to assemble and install without the need for on-site masonry.

[0037] In some embodiments, the feed pipe 10, the base beam 20, and the first discharge pipe 30 are single-tube structures, which are tubular components made of a first high-temperature material. The base beam 20 can be an integral tubular component, or a tubular component formed by segmented tubular components fixedly connected together by a fastening structure or fasteners. When the base beam 20 is a segmented tubular component, it is preferably arranged to be spliced at the location where the feed pipe 10 and the first discharge pipe 30 need to be connected, so that the feed pipe 10 and the first discharge pipe 30 are conveniently connected. For example, when a first hole portion 23 and a second hole portion 24 are provided on the base beam 20 to connect the feed pipe 10 and the first discharge pipe 30, the segmentation of the base beam 20 can be provided at the first hole portion 23 and / or the second hole portion 24, and the first hole portion 23 and / or the second hole portion 24 are formed by aligning the two sections of the structure, and the aligning portions are fixedly connected by fasteners.

[0038] The first high-temperature material primarily refers to a non-metallic, high-temperature-resistant material containing carbon, primarily including graphite, silicon carbide, and silicon carbide-graphite composites. In the present invention, the first high-temperature material is a relatively low-cost graphite material, and the tubular component made of the first high-temperature material is a graphite tube. In other embodiments, the first high-temperature material may also be a slightly more expensive silicon carbide, silicon carbide-graphite composite, or the like.

[0039] In this embodiment, the feed pipe 10, the base beam 20, and the first discharge pipe 30 are double-layer sleeve structures:

[0040] The feed pipe 10 includes an outer feed pipe 11 and an inner feed pipe 12, wherein the outer feed pipe 11 is sleeved outside the inner feed pipe 12;

[0041] The first discharge pipe 30 includes a first discharge outer pipe 31 and a first discharge inner pipe 32 , wherein the first discharge outer pipe 31 is sleeved outside the first discharge inner pipe 32 ;

[0042] The base beam 20 includes a base beam outer tube 21 and a base beam inner tube 22 , and the base beam outer tube 21 is sleeved outside the base beam inner tube 22 .

[0043] When the feed pipe 10, base beam 20, and first discharge pipe 30 are double-layer sleeve structures, the feed outer pipe 11, base beam outer pipe 21, and first discharge outer pipe 31 are tubular components made of a first high-temperature material, and the feed inner pipe 12, base beam inner pipe 22, and first discharge inner pipe 32 are tubular components made of a second high-temperature material.

[0044] Furthermore, the feed pipe outer tube 11, the base beam outer tube 21, the first discharge outer tube 31, the feed inner tube 12, the base beam inner tube 22, and the first discharge inner tube 32 are all integrated tubes. Of course, they can also be segmented tubes instead of integrated tubes. For example, the base beam outer tube 21 and the base beam inner tube 22 can be configured as segmented tubes, with multiple sections assembled together to form an integral structure. For ease of description, this embodiment preferably describes the feed pipe outer tube 11, the base beam outer tube 21, the first discharge outer tube 31, the feed inner tube 12, the base beam inner tube 22, and the first discharge inner tube 32 as an integrated tube.

[0045] The second high-temperature material is a corundum material (mainly composed of Al2O3), and the tubular component made of the second high-temperature material is a corundum tube.

[0046] By setting the feed tube 10, the base beam 20, and the first discharge tube 30 as a double-layer sleeve structure, not only can the graphite tube be prevented from being oxidized at high temperature, but also the graphite particles in the graphite tube can be prevented from falling into the glass liquid and affecting the quality of the glass liquid. In this way, the advantages of the graphite tube can be brought into play: high temperature resistance, low cost, and high processing and assembly precision, while the disadvantages of the graphite tube can be avoided: easy high temperature oxidation and easy slagging at high temperature.

[0047] When the feed tube 10, the base beam 20, and the first discharge tube 30 are single-tube structures, they are suitable for producing special glass, such as microcrystalline glass. At this time, the graphite particles of the graphite tube fall into the glass liquid, which helps the production of microcrystalline glass. Therefore, the graphite tube can directly contact the glass liquid without the need to install a corundum tube inside the graphite tube.

[0048] For conventional ultra-thin glass production, the feed tube 10, base beam 20, and first discharge tube 30 are preferably configured as a double-layer tube structure: a graphite tube as the outer tube and a corundum tube as the inner tube, with the corundum tube nested within the graphite tube. In other embodiments, when the selection of the first high-temperature material changes, adaptive adjustments can be made.

[0049] Furthermore, when the base beam inner tube 22 is disposed within the base beam outer tube 21, the base beam inner tube 22 is disposed along a third direction Z, which may be the same as or different from the first direction X. For example, in some embodiments, the base beam inner tube 22 is disposed horizontally, in which case the third direction Z is the same as the first direction X. For another example, in some embodiments, the base beam inner tube 22 is disposed at a certain angle relative to the horizontal plane, in which case the third direction Z is inclined relative to the first direction X.

[0050] The outer base tube 21 is arranged horizontally along the first direction X, which facilitates the installation of the feed pipe 10 and the first discharge pipe 30. The inner base tube 22 is arranged along the third direction Z, so that the flow direction of the molten glass can be flexibly set as needed, so that the molten glass does not have to flow horizontally into the first discharge pipe 30.

[0051] Furthermore, the base beam 20 is connected to the feed pipe 10 and the first discharge pipe 30 via threads. The base beam 20 is provided with a first hole portion 23 and a second hole portion 24 arranged along the second direction Y. The first hole portion 23 and the second hole portion 24 are through holes and are spaced a certain distance apart.

[0052] The first end of the feed pipe 10 is threadedly connected to the first hole portion 23, and the first end of the first discharge pipe 30 is threadedly connected to the second hole portion 24. The feed pipe 10 and the first discharge pipe 30 are parallel and spaced apart.

[0053] When the feed pipe 10, the first discharge pipe 30, and the base beam 20 are double-layer sleeve structures, external threads can be processed on the first ends of the feed outer pipe 11 and the first discharge outer pipe 31, and corresponding internal threads can be processed at the first hole portion 23 and the second hole portion 24, so that the feed outer pipe 11 and the first discharge outer pipe 31 are threadedly connected to the first hole portion 23 and the second hole portion 24.

[0054] Since the graphite tube has a high processing precision, the feed pipe 10, the base beam 20 and the first discharge pipe 30 can be stably connected together through threaded connection.

[0055] Furthermore, in order to save space, the feed pipe 10 and the first discharge pipe 30 are arranged on the same side of the base beam 20, and the base beam 20 is laterally connected to the bottoms of the feed pipe 10 and the first discharge pipe 30. Of course, in other embodiments, the feed pipe 10 and the first discharge pipe 30 can also be arranged on different sides of the base beam 20.

[0056] Furthermore, to facilitate the insertion of the base beam inner tube 22 into the base beam outer tube 21, a center hole 211 is provided in the base beam outer tube 21. The center hole 211 extends from the first end of the base beam outer tube 21 along the third direction Z, passes through the first hole portion 23, and is in communication with the second hole portion 24.

[0057] The base beam inner tube 22 may be inserted into the central hole 211 from the first end of the base beam outer tube 21 , thereby being assembled inside the base beam outer tube 21 .

[0058] To prevent molten glass from flowing out of the center hole 211 and causing leakage, a first connecting tube 40 is disposed within the first hole portion 23 along the second direction Y. A first docking hole 43 is provided in the first connecting tube 40, distal from the first end of the base beam 20. A solid structure is formed at the location corresponding to the first docking hole 43, sealing the center hole 211. This prevents molten glass from flowing out of the first end of the base beam 20 and allows it to flow through the first docking hole 43 to the base beam inner tube 22.

[0059] During installation, the base beam inner tube 22 is first inserted into the center hole 211 from the first end of the base beam 20, ensuring that the first end of the base beam inner tube 22 does not extend into the first hole portion 23. The first connecting tube 40 is then installed into the first hole portion 23, with the first docking hole 43 facing the base beam inner tube 22 and aligned with the center hole 211. The base beam inner tube 22 is then moved along the third direction Z so that the first end of the base beam inner tube 22 is inserted into the first docking hole 43, thereby forming a connection therewith. Preferably, the first end of the base beam inner tube 22 extends into the first connecting tube 40.

[0060] In this way, when the high-temperature molten glass flows into the first connecting tube 40, it can flow to the base beam inner tube 22, while the rest of the positions are sealed and cannot flow out.

[0061] The first connecting pipe 40 can be a single-tube structure or a double-tube structure.

[0062] When the feed pipe 10 , the base beam 20 , and the first discharge pipe 30 are single-tube structures, the first connecting pipe 40 is preferably a single-tube structure, which is a tubular component made of a first high-temperature material, such as a graphite tube.

[0063] In this embodiment, the feed pipe 10, base beam 20, and first discharge pipe 30 are configured as a double-layered sleeve structure. The first connecting pipe 40 is also configured as a double-layered sleeve structure, comprising a first connecting outer pipe 41 and a first connecting inner pipe 42. The first connecting outer pipe 41 is sleeved outside the first connecting inner pipe 42. The first connecting outer pipe 41 is a one-piece tubular component made of a first high-temperature material, and the first connecting inner pipe 42 is a one-piece tubular component made of a second high-temperature material. In this embodiment, the first connecting outer pipe 41 is a graphite tube, and the first connecting inner pipe 42 is a corundum tube.

[0064] Correspondingly, through holes are respectively provided at corresponding positions of the first connecting outer tube 41 and the first connecting inner tube 42 to form the first docking holes 43 .

[0065] In this embodiment, the first connecting tube 40 is configured as a double-layer sleeve structure, also to prevent the graphite tube from being oxidized at high temperature and the graphite particles in the graphite tube from entering the glass liquid.

[0066] In addition, setting the pipe fittings of the feed part in the form of a segmented feed pipe 10 and a first connecting pipe 40 is not only conducive to reducing costs, but also conducive to installation, as well as disassembly and replacement of parts and reuse of the feed pipe 10. As is well known, the longer the graphite tube, the higher the cost. The cost of one feed outer tube 11 and one first connecting outer tube 41 is lower than that of a whole tube of equivalent length. Therefore, this structure can reduce costs. In addition, if disassembly and assembly is required (during maintenance), the feed pipe 10 can be removed first, and then the first connecting pipe 40 can be disassembled and assembled separately. Even if the first connecting pipe 40 is stuck inside the base beam 20 and cannot be removed, only the first connecting pipe 40 can be broken, so that the feed pipe 10 can be reused, thereby reducing the overall cost.

[0067] Furthermore, to ensure that the glass material is fully melted within the feed tube 10, a first baffle 51 is provided within the first hole 23. The first baffle 51 is disposed transversely between the feed tube 10 and the first connecting tube 40 and is provided with a plurality of through-holes for the glass liquid to flow through. The first baffle 51 is made of a second high-temperature material, which in this embodiment is a corundum plate.

[0068] The first partition 51 can slow down the speed of the glass liquid flowing downward, thereby extending the time that the glass raw material stays in the feed pipe 10. In this way, the glass raw material can stay in the feed pipe 10 for a longer time, thereby being melted at high temperature in the feed pipe 10, and preventing the raw material from being incompletely melted and flowing into the next process.

[0069] Furthermore, to facilitate installation, the first hole portion 23 is configured as a stepped hole, comprising a first threaded hole portion 231 and a first light hole portion 232. The diameter of the first light hole portion 232 is smaller than that of the first threaded hole portion 231, forming a stepped hole. The center hole 211 vertically penetrates the first light hole portion 232.

[0070] Furthermore, the first connecting tube 40 is sleeved in the first light hole portion 232 , the first partition 51 is arranged in the first threaded hole portion 231 and abuts against the first light hole portion 232 , and the first end of the feeding tube 10 is threadedly connected to the first threaded hole portion 231 .

[0071] Furthermore, a plug 60 is provided at the end of the first hole 23 opposite the feed pipe 10. The plug 60 seals the first hole 23 and can be opened to discharge slag when needed. The plug 60 is sealed to the first hole 23 and has an openable cover. When it is necessary to clear slag from the first connecting pipe 40, the plug 60 can be opened to discharge the slag.

[0072] Furthermore, a second connecting tube 70 is disposed within the second hole 24 and arranged along the second direction Y. The second connecting tube 70 is used to connect the first discharge tube 30 and the base beam 20. A second docking hole 73 is provided at the end of the second connecting tube 70 away from the base beam 20. The portion corresponding to the second docking hole 73 is a solid structure.

[0073] During installation, before installing the base beam inner tube 22, the second connecting tube 70 can be first installed into the second hole portion 24, and the second docking hole 73 can be aligned with the center hole 211. Subsequently, the base beam inner tube 22 can be inserted into the center hole 211, and the second end of the base beam inner tube 22 can be inserted into the second docking hole 73 and connected to the second docking hole 73. Alternatively, after the base beam inner tube 22 and the first connecting tube 40 are installed, the base beam inner tube 22 can be moved along the third direction Z so that the base beam inner tube 22 does not extend into the range of the second hole portion 24. The second connecting tube 70 can then be installed into the second hole portion 24, and the second docking hole 73 can be aligned with the center hole 211. The base beam inner tube 22 can then be moved along the third direction Z so that the second end of the base beam inner tube 22 can be inserted into the second docking hole 73 and connected to the second docking hole 73.

[0074] In this embodiment, after the first connecting tube 40, the second connecting tube 70 and the base beam inner tube 22 are installed, both ends of the base beam inner tube 22 extend into the first connecting tube 40 and the second connecting tube 70 respectively, so as to avoid leakage at the interface.

[0075] The second connecting pipe 70 can be a single-tube structure or a double-tube structure.

[0076] When the feed pipe 10 , the base beam 20 , and the first discharge pipe 30 are single-tube structures, the second connecting pipe 70 is preferably a single-tube structure, which is an integral tubular component made of a first high-temperature material, such as a graphite tube.

[0077] In this embodiment, the feed pipe 10, base beam 20, and first discharge pipe 30 are configured as a double-layered sleeve structure. The second connecting pipe 70 is also configured as a double-layered sleeve structure, comprising a second connecting outer pipe 71 and a second connecting inner pipe 72. The second connecting outer pipe 71 is sleeved over the second connecting inner pipe 72. The second connecting outer pipe 71 is a one-piece tubular component made of a first high-temperature material, and the second connecting inner pipe 72 is a one-piece tubular component made of a second high-temperature material. In this embodiment, the second connecting outer pipe 71 is a graphite tube, and the second connecting inner pipe 72 is a corundum tube.

[0078] Correspondingly, through holes are respectively provided at corresponding positions of the second connecting outer tube 71 and the second connecting inner tube 72 to form the second docking hole 73 .

[0079] The second connecting tube 70 is configured as a double-layer sleeve structure, also to prevent the graphite tube from being oxidized at high temperature and to prevent graphite particles in the graphite tube from entering the glass liquid.

[0080] In addition, the pipe fittings of the discharge part are arranged in the form of a segmented first discharge pipe 30 and a second connecting pipe 70, which is not only conducive to reducing costs, but also convenient for installation, as well as for disassembly and replacement of parts and reuse of the feed pipe 10. As is generally known, the longer the length of the graphite tube, the higher the cost. The cost of one first discharge outer tube 31 and one second connecting outer tube 71 is lower than that of a whole tube of equivalent length. Therefore, this structure can reduce costs. In addition, if disassembly and assembly is required (during maintenance), the first discharge pipe 30 can be removed first, and then the second connecting pipe 70 can be disassembled and assembled separately. Even if the second connecting pipe 70 is stuck inside the base beam 20 and cannot be removed, only the second connecting pipe 70 can be broken, so that the first discharge pipe 30 can be reused, thereby reducing production costs.

[0081] In order to allow the molten glass flowing out of the base beam 20 to enter the second connecting pipe 70 and then flow to the first discharge pipe 30 , a sealing plate 80 for sealing the second connecting pipe 70 is provided in the second hole portion 24 .

[0082] The sealing plate 80 is disposed at the end of the second connecting tube 70 opposite the first discharge tube 30. In other words, the first discharge tube 30 and the sealing plate 80 are respectively disposed at both ends of the second connecting tube 70. The sealing plate 80 seals one end of the second connecting tube 70, thereby preventing the molten glass from flowing in the direction opposite to the first discharge tube 30, so that the molten glass can only flow in the direction of the first discharge tube 30.

[0083] The sealing plate 80 is in direct contact with the glass liquid and is preferably made of the second high-temperature material. In this embodiment, it is a corundum plate.

[0084] Furthermore, to reduce the flow rate of the molten glass, a second baffle 52 is provided within the second hole 24. The second baffle 52 is disposed transversely between the first discharge pipe 30 and the second connecting pipe 70 and is provided with a plurality of through-holes for the molten glass to flow through. The second baffle 52 is made of a second high-temperature material, which in this embodiment is a corundum plate.

[0085] The second partition 52 can slow down the flow of the molten glass and prevent the flow of unmelted residue, which is conducive to cooling the molten glass and allowing the residue to settle to the bottom.

[0086] Furthermore, to further enhance cooling, a second discharge pipe 90 is coaxially disposed within the first discharge pipe 30 and spaced apart therefrom. The first discharge pipe 30 and the second discharge pipe 90 are spaced apart to form a first discharge channel L1, while the interior of the second discharge pipe 90 forms a second discharge channel L2. The first discharge channel L1 and the second discharge channel L2 are interconnected, allowing molten glass to flow from the second connecting pipe 70 into the first discharge channel L1 and then into the second discharge channel L2.

[0087] Furthermore, the second end of the first discharge pipe 30, that is, the end opposite to the second connecting pipe 70, is connected to the second end of the second discharge pipe 90, so that the second end of the first discharge channel L1, that is, the end away from the second connecting pipe 70, is connected to the second discharge channel L2. In this way, the glass liquid can flow through a longer path as much as possible.

[0088] The first end of the second discharge pipe 90 passes through the second connecting pipe 70 and the sealing plate 80 to form a discharge port 93 for allowing the glass liquid in the second discharge channel L2 to flow out.

[0089] In this embodiment, the second ends of the first discharge pipe 30 and the second discharge pipe 90 are the top ends, and the first ends are the bottom ends. In this way, when the glass liquid flows from the base beam 20 into the second connecting pipe 70, it first flows against gravity to the first discharge channel L1, then flows into the inside of the second discharge pipe 90 and flows through the second discharge channel L2, and finally flows out from the bottom end discharge port 93 of the second discharge pipe 90.

[0090] By arranging a second discharge pipe 90 inside the first discharge pipe 30, the circulation channel of the glass liquid can be extended within a sufficiently small space, so that the stroke of the glass liquid is increased, which is beneficial to the cooling of the glass liquid, so that the temperature of the glass liquid flowing out of the discharge port 93 is reduced to the required discharge temperature. In addition, the upward flow of the glass liquid against gravity in the first discharge channel L1 also has the following advantages: it is beneficial for the bubbles in the glass liquid to overflow and eliminate the bubbles in the glass liquid; it is beneficial for the impurities in the glass liquid to settle to the bottom, thereby improving the quality of the glass liquid and improving the clarification effect. In the present invention, the structural design of the first discharge pipe 30 and the second discharge pipe 90 can balance the cooling demand and the clarification demand before the glass liquid is discharged, so that the discharged glass liquid can meet the temperature requirement and can be clarified (improving the quality of the glass liquid).

[0091] To support the second discharge pipe 90, a third partition 53 is provided between the first and second discharge pipes 30, 90. The third partition 53 is disposed transversely between the first and second discharge pipes 30, 90, supporting the second discharge pipe 90 and preventing it from wobbling within the first discharge pipe 30. The third partition 53 is provided with a plurality of through-holes for the flow of molten glass.

[0092] The third partition plate 53 is in direct contact with the glass liquid, and therefore, the third partition plate 53 is made of the second high-temperature material. In this embodiment, the third partition plate 53 is a corundum plate with holes.

[0093] In this embodiment, the third partition plate 53 is disposed near the second ends of the first discharge pipe 30 and the second discharge pipe 90. In other words, the second end of the second discharge pipe 90 passes through the third partition plate 53 to form a free end and is in communication with the interior of the first discharge pipe 30.

[0094] In some embodiments, the second discharge pipe 90 is a single-tube structure, with its second end extending from the third partition plate 53 to form a free end, and its first end inserted into the sealing plate 80. The second discharge pipe 90 directly contacts the molten glass and is a tubular component made of a second high-temperature material, preferably a corundum tube.

[0095] In this embodiment, the second discharge tube 90 is a double-layered sleeve structure, comprising a second inner discharge tube 92 and a second outer discharge tube 91. The second outer discharge tube 91 is sleeved over the second inner discharge tube 92. Both the second outer discharge tube 91 and the second inner discharge tube 92 are in direct contact with the molten glass and are tubular components made of the second high-temperature material. In this embodiment, both are corundum tubes.

[0096] The second end of the second discharge inner tube 92 passes through the third partition plate 53 and extends into the first discharge tube 30 to form a free end. The first end of the second discharge inner tube 92 passes through the second partition plate 52, the second connecting tube 70, and the sealing plate 80 in sequence and is inserted into the sealing plate 80. The second discharge inner tube 92 is an integrated tube.

[0097] The second discharge outer tube 91 can be an integral tube or a segmented tube.

[0098] When the second discharge outer tube 91 is an integrated tube, both ends thereof are respectively abutted between the third partition plate 53 and the sealing plate 80 .

[0099] When the second discharge outer tube 91 is a segmented tube, it can be divided into two sections, with both ends of one section abutting between the third partition plate 53 and the second partition plate 52 , and both ends of the other section abutting between the second partition plate 52 and the sealing plate 80 .

[0100] The second discharge outer tube 91 is arranged in contact with the third partition 53 and the sealing plate 80 and the second partition 52, which is conducive to the installation of the third partition 53. Specifically, the second end of the second discharge outer tube 91 can provide support for the installation of the third partition 53, so that the third partition 53 can be overlapped on the end of the second discharge outer tube 91 without the need for an additional positioning step structure. The second discharge inner tube 92 is inserted into the third partition 53 and is sleeved on the inside of the second discharge outer tube 91. In this way, the positioning of each component can be achieved through a simple assembly structure without the need for additional fasteners. The stability of the structure can be maintained by relying on its own structure. Moreover, the double-layer structure is more conducive to improving the service life of the second discharge tube 90, avoiding high-temperature erosion of the inner and outer surfaces of the same pipe, thereby improving the service life.

[0101] Furthermore, in order to control the temperature in each channel, a first heating device is provided outside the feed pipe 10, and a second heating device 100 is provided outside the first discharge pipe 30. The first heating device and the second heating device 100 are electromagnetic induction heating devices, which are arranged outside the tube in the form of a spiral tube, and can heat the graphite tube. When the graphite tube of the feed pipe 10 is heated, the temperature inside the feed pipe 10 can be raised to the required temperature, thereby melting the glass raw materials and making the glass raw materials melt into glass liquid in the feed pipe 10. The second heating device 100 can be used for pre-kiln baking and for adjusting the process temperature during continuous production. For example, when the tubular glass kiln is just started, the entire kiln needs to be heated. At this time, the second heating device 100 can be started for heating to heat the first discharge pipe 30 to the required temperature. This not only prevents excessive waste of molten glass due to a significant temperature difference between the temperature inside the first discharge pipe 30 and the temperature of the molten glass, but also gradually heats the first discharge pipe 30 during heating. This prevents the high-temperature molten glass from suddenly applying high temperature to the first discharge pipe 30 and causing damage to the first discharge pipe 30, such as causing the internal corundum tube of the first discharge pipe 30 to burst. Furthermore, heating the first discharge pipe 30 with the second heating device 100 preheats the first discharge pipe 30, preventing the newly flowing molten glass from losing its temperature too quickly, thereby preventing the molten glass from losing its fluidity and clogging the flow channel.

[0102] Furthermore, the spiral tube of the second heating device 100 is configured as a hollow copper tube with a coolant flowing therein, which can be used for both electromagnetic induction heating of the graphite tube and cooling.

[0103] When the glass kiln is first started, if it is necessary to heat the kiln to raise the room temperature to the required temperature, the first heating device and the second heating device 100 can be turned on. At this time, the second heating device 100 can be used to heat the first discharge pipe 30. When the kiln is working normally, the second heating device 100 can be controlled to heat or not heat according to the requirements of the glass production process. When heating is required, the second heating device 100 is turned on, which can heat the first discharge pipe 30 to maintain the temperature inside the first discharge pipe 30. When heating is not required, the second heating device 100 is turned off. At this time, the coolant inside the second heating device 100 can circulate and take away the heat, and the glass liquid in the first discharge pipe 30 can be cooled, thereby facilitating cooling the glass liquid to the required temperature for discharge.

[0104] By setting the spiral tube of the second heating device 100 as a hollow copper tube and passing coolant into it, the function of the second heating device 100 can be flexibly adjusted so that it can be used for both heating and temperature regulation, as well as cooling, thereby meeting the adjustment needs of the glass production process.

[0105] Furthermore, to prevent the tubular components made of the first high-temperature material from oxidizing at high temperatures, the outer walls of the feed outer tube 11, the base beam outer tube, and the first discharge outer tube 31 are coated with a high-temperature anti-oxidation material. This seals the surface of the graphite tube and prevents oxidation at high temperatures. The high-temperature anti-oxidation material can be a well-known coating.

[0106] In the most preferred embodiment of the present invention, the feed outer tube 11, the base beam outer tube 21, and the first discharge outer tube 31 made of graphite tubes are connected to form the main structure. Then, corundum tubes (feed inner tube 12, base beam inner tube 22, and first discharge inner tube 32) are respectively arranged inside the graphite tubes to prevent the glass liquid from directly contacting the graphite tubes, thereby both leveraging the advantages of the graphite tubes and avoiding their disadvantages. In order to facilitate the installation of the base beam inner tube 22, small sections of connecting tubes, namely the first connecting tube 40 and the second connecting tube 70, are respectively arranged in the holes where the feed tube 10, the first discharge tube 30, and the base beam 20 are connected. The first connecting tube 40 and the second connecting tube 70 also adopt the structure of a graphite tube sheathed with a corundum tube. This is convenient for installation and helps reduce costs.

[0107] Although the present invention is disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced with similar or equivalent elements known to those skilled in the art.
