Technical Field

[0001] The present application relates to the technical field of glass forming, and in particular to a heating mechanism and a glass forming device for glass forming. Background Art

[0002] Glass forming equipment typically includes a discharge mechanism, a forming mold, and a pulling mechanism. The discharge mechanism directs molten glass to the forming mold, where it cools and forms into glass sheets or strips. In the field of optical glass forming technology, forming glass sheets that are wider and thinner is often difficult. For example, glass sheets with a width greater than 200 mm and a thickness less than 10 mm are difficult to spread out during forming due to the high viscosity of the molten glass. This can result in a thick center and thin edges, making it difficult to meet the forming requirements of the corresponding glass sheets. Utility Model Content

[0008] When the above-mentioned heating mechanism is used to heat molten glass, an external combustion medium such as natural gas is input into the ventilation cavity of the heating component through the gas supply component, and the combustion medium leaks into the combustion cavity from the gas outlet, and then ignites the combustion medium in the combustion cavity through the gas groove. The combustion medium burns in the combustion cavity of the heat-insulating component and heats the heat-insulating component, so that the heat-insulating component can transfer heat to the molten glass, heat the molten glass, increase the fluidity of the molten glass, reduce the viscosity of the molten glass, and slow down the solidification rate of the molten glass, so that the molten glass can be fully spread to form a glass sheet, which is beneficial to reducing the probability that the shape and specifications of the formed glass sheet do not meet the requirements due to the excessive viscosity of the molten glass, and improving the forming yield of the glass sheet. In addition, the setting of the heat-insulating component can slow down the loss and dissipation of heat while transferring heat to the molten glass, improve the utilization efficiency of heat, and make the temperature distribution of the heating mechanism more stable and controllable, thereby improving the safety performance of the heating mechanism and the forming quality of the glass sheet.

[0009] In one embodiment, the thermal insulation component includes a bottom insulation board and multiple side insulation boards, and the multiple side insulation boards are arranged on the same side of the bottom insulation board and are connected in sequence along the periphery of the bottom insulation board. The side of the bottom insulation board facing away from the combustion chamber is used to be opposite to the glass liquid, and the first surface is opposite to the side of the bottom insulation board facing the combustion chamber.

[0010] In one embodiment, the two side heat insulation plates are arranged opposite to each other, and the two opposite sides of the heating element are respectively opposite to the two opposite side heat insulation plates and are arranged at a distance from each other.

[0013] In one embodiment, the ends of the plurality of side insulation boards away from the bottom insulation board and the two side surfaces opposite to the heating element are jointly arranged to form the two air grooves.

[0014] In one embodiment, the heating mechanism further includes a plurality of supporting structures, which are spaced apart on the first surface and connected to the first surface and the bottom insulation board.

[0015] In one embodiment, one of the side insulation plates includes a partition body and a protective structure, the partition body is connected to the bottom insulation plate and the other side insulation plates, and the protective structure is connected to the partition body and protrudes toward the combustion chamber to form a protective groove on the side facing away from the combustion chamber for protecting the discharge pipe.

[0030] See Figure 1 and Figure 2 , Figure 1 Schematic diagram of the structure of some components of the glass forming device 10 in some embodiments. Figure 2 Schematic diagram of the heating mechanism 20 in some embodiments. The heating mechanism 20 provided herein can be used in glass forming, for example, in a glass forming apparatus 10, to heat molten glass and increase its fluidity, thereby allowing it to spread fully and forming a glass sheet that meets required shape and size specifications.

[0031] In some embodiments, a glass forming apparatus 10 includes a material pool (not shown), a discharge pipe 11, a forming mold 12, and a pulling mechanism 13. Liquid glass is formed in the material pool and can be transferred from the material pool to the forming mold 12 via the discharge pipe 11, where it is formed into a glass sheet. The pulling mechanism 13 can pull the glass sheet being formed in the forming mold 12, thereby ensuring that the liquid glass can be continuously formed in the forming mold 12. During the glass forming process, a heating mechanism 20 is disposed on the forming mold 12 and adjacent to the discharge pipe 11. The heating mechanism 20 can heat the liquid glass in the forming mold 12, delaying its solidification and allowing it to fully spread out in the forming mold 12.

[0032] Further, combined with Figure 2 and Figure 3As shown, in some embodiments, the heating mechanism 20 includes a heat-insulating element 21, a heat supply element 22, and an air supply element 23. The heat-insulating element 21 is a hollow structure, and a combustion chamber (not shown) is defined therein. The heat-insulating element 21 also includes an air groove 215 that connects the combustion chamber to the outside air. The heat-insulating element 22 is fixedly disposed within the combustion chamber of the heat-insulating element 21 and has a first surface 221. The first surface 221 is located within the heat-insulating element 21 and is opposite one of the inner surfaces of the heat-insulating element 21. The first surface 221 is spaced apart from the surface of the heat-insulating element 21 opposite the first surface 221. The gap between the first surface 221 and the heat-insulating element 21 connects to the air groove 215. The heat-insulating element 22 is a hollow structure, and a ventilation chamber (not shown) is defined therein. The heat-insulating element 22 also includes an air outlet 223 that connects to the ventilation chamber and passes through the first surface 221. The air outlet 223 connects the ventilation chamber and the combustion chamber. The air supply component 23 is connected to the ventilation cavity and passes through the thermal insulation component 21. The part of the air supply component 23 located outside the thermal insulation component 21 is used to connect with an external source of combustion medium, such as an external natural gas pipeline or natural gas storage container, so that combustion medium such as natural gas can be input into the ventilation cavity through the air supply component 23.

[0033] It is understood that during the forming process of the glass liquid, the heating mechanism 20 is provided at the corresponding position of the glass liquid. Figure 1 Above the illustrated position, a combustion medium, such as natural gas, is introduced into the vent cavity and leaks into the combustion chamber from gas outlet 223. An ignition device, such as a spray gun, extends through gas slot 215 into the combustion chamber, igniting the combustion medium and causing combustion within the combustion chamber. The heat generated by the combustion of the combustion medium heats the thermal insulation element 21, which in turn transfers the heat to the molten glass, improving its fluidity and delaying its solidification, thereby facilitating its full spreading.

[0034] The heating mechanism 20 heats the molten glass during the forming process, increasing its fluidity, reducing its viscosity, and slowing its solidification rate, allowing it to fully spread out and form a glass sheet. This helps reduce the probability of the formed glass sheet not meeting the required shape specifications due to excessive viscosity, thereby improving the yield rate of the glass sheet. For example, the heating mechanism 20 can be used in the forming process of glass sheets with a larger width and smaller thickness, such as glass sheets with a width greater than 200 mm and a thickness less than 10 mm. When glass with a larger width and smaller thickness flows through the discharge pipe 11 and into the forming mold 12, it typically has a higher viscosity. If not heated in the forming mold 12, the molten glass will not easily spread out, and may become thick in the middle and thin at the edges, making it difficult to meet the forming requirements of wide and thin glass sheets. The heating mechanism 20 heats the molten glass in the forming mold 12, allowing it to fully spread out and form a wide and thin glass sheet with uniform thickness throughout, thereby improving the yield rate and quality of the wide and thin glass sheets.

[0035] Furthermore, the traditional method of directly igniting and heating the mold directly under the forming mold results in poor heat conduction due to the large thickness of the forming mold, resulting in an uneven and difficult-to-control temperature distribution, which can easily cause dust to fly, affecting the safety of the heating process. In the aforementioned heating mechanism 20, the provision of the heat-insulating member 21 can not only conduct heat to the molten glass, but also slow down heat loss and dissipation, thereby improving heat utilization efficiency and making the temperature distribution of the heating mechanism 20 more stable and controllable, thereby improving the safety of the heating mechanism 20 and the forming quality of the glass sheet.

[0036] Combine Figure 2 and Figure 3 As shown, in some embodiments, the thermal insulation member 21 includes a bottom insulation board 211 and a plurality of side insulation boards 212. The plurality of side insulation boards 212 are disposed on the same side of the bottom insulation board 211 and are sequentially connected along the periphery of the bottom insulation board 211. The side of the bottom insulation board 211 facing away from the combustion chamber is used to face the molten glass, and the first surface 221 faces the side of the bottom insulation board 211 facing the combustion chamber. The bottom insulation board 211 can be a generally square flat plate-shaped structure having four sequentially connected edges. Four side insulation boards 212 can be provided, and the four side insulation boards 212 are respectively connected to the four edges of the bottom insulation board 211. The combustion chamber is formed between the bottom insulation board 211 and the plurality of side insulation boards 212.

[0037] In some embodiments, two side insulation plates 212 are disposed opposite each other, and opposite sides of the heating element 22 are spaced apart from and opposite to the two opposing side insulation plates 212. The gap between the heating element 22 and at least one of the side insulation plates 212 communicates with the gas groove 215. It is understood that when a combustion medium, such as natural gas, leaks from the gas outlet 223 into the space between the first surface 221 and the bottom insulation plate 211, the combustion level between the first surface 221 and the bottom insulation plate 211 is higher than in the rest of the combustion chamber, for example, higher than the gap between the heating element 22 and the two side insulation plates 212. The side of the bottom insulation plate 211 facing away from the combustion chamber is used to face the molten glass on the forming mold 12. This facilitates the sufficient conduction of heat generated by combustion to the molten glass via the bottom insulation plate 211 and also helps extend the path length for heat dissipation to the gas groove 215, thereby maintaining heat and delaying heat dissipation and loss.

[0038] In some embodiments, the thermal insulation component 21 is provided with two air grooves 215, and the two air grooves 215 are respectively provided on opposite sides of the heating component 22. The two air grooves 215, the gap between the heating component 22 and the side insulation board 212, and the gap between the first surface 221 and the bottom insulation board 211 together form a ventilation channel. The ventilation channel can be regarded as a path formed by one of the air grooves 215 to the gap between the heating component 22 and one of the side insulation boards 212, to the gap between the first surface 221 and the bottom insulation board 211, to the gap between the heating component 22 and the other side insulation board 212, and then to the other air groove 215. During ignition, the ignition device can be extended into the combustion chamber through any air groove 215 to ignite the combustion medium. The provision of two air grooves 215 to form a ventilation channel can continuously provide oxygen to the combustion of the combustion medium in the combustion chamber, thereby improving the stability of combustion.

[0039] The formation method of the two air grooves 215 is not limited. In some embodiments, the thermal insulation component 21 further includes a top heat insulation board 213. The top heat insulation board 213 is provided on the side of the heating component 22 facing away from the bottom heat insulation board 211 and is connected to the side heat insulation board 212. The two air grooves 215 are opened on the top heat insulation board 213 and pass through the top heat insulation board 213. The top heat insulation board 213 can also be a roughly square flat plate-shaped structure, with the four edges of the top heat insulation board 213 respectively connected to the ends of the four side heat insulation boards 212 away from the bottom heat insulation board 211. The top heat insulation board 213 is provided together with the side heat insulation boards 212 and the bottom heat insulation board 211 to form a combustion chamber, which can further enhance the heat preservation effect of the thermal insulation component 21, slow down the heat loss, and provide structural protection for the heating component 22.

[0040] Of course, in other embodiments, the top insulation board 213 may also be omitted, and multiple side insulation boards 212 are jointly arranged at the front end away from the bottom insulation board 211 and the two side surfaces opposite to the heating component 22 to form two air grooves 215, which is also beneficial to slowing down the heat dissipation from the air grooves 215, and at the same time is beneficial to simplifying the structure of the heating mechanism 20 and reducing the material and preparation costs of the heating mechanism 20.

[0041] Please see again Figure 2 In some embodiments, the heating mechanism 20 further includes a plurality of support structures 24, which are spaced apart on the first surface 221 and connected to the first surface 221 and the side of the bottom heat insulation board 211 facing the combustion chamber. The heating element 22 may be roughly a cubic structure, the first surface 221 may be roughly square, and four support structures 24 may be provided, with the four support structures 24 respectively provided at the four corners of the first surface 221. The lengths of the plurality of support structures 24 may be roughly equal, so that the vertical distances between the first surface 221 and the surface of the bottom heat insulation board 211 facing the combustion chamber are roughly equal. The provision of the support structures 24 can improve the stability and reliability of the installation of the heating element 22 in the thermal insulation element 21, and at the same time make the heating of the bottom heat insulation board 211 more uniform, which is beneficial to improving the uniformity of the temperature distribution and improving the heating effect on the glass liquid.

[0042] In some embodiments, the heating element 22 is provided with a plurality of air outlets 223, which are arranged in a uniform array on the first surface 221. The uniform array of air outlets 223 allows each air outlet 223 to leak out combustion medium, thereby improving the uniformity of heating across the bottom insulation board 211 and enhancing the heating effect of the heating mechanism 20 on the molten glass. The aperture and number of the air outlets 223 are not limited and can be specifically set based on the size requirements of the heating mechanism 20 and the heating requirements of the molten glass. For example, in some embodiments, the number of air outlets 223 can be 60-80, and the diameter of the air outlets 223 can be 1 mm-2 mm.

[0043] Combine Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, one of the side heat insulation panels 212 includes a partition body 2121 and a protective structure 2122. The partition body 2121 can be a square flat plate structure with a notch. The protective structure 2122 is connected to the partition body 2121 and protrudes toward the combustion chamber to form a protective groove 2123 on the side facing away from the combustion chamber. The protective structure 2122 can be an arc-shaped plate structure that protrudes toward the combustion chamber. Figure 1 and Figure 2As shown, it should be noted that during the forming process of the molten glass, the heating mechanism 20 can be placed on the forming mold 12, with the bottom insulation board 211 facing the forming mold 12 and opposite the molten glass on the forming mold 12. The side insulation board 212 provided with the protective structure 2122 is placed toward the discharge pipe 11. The discharge pipe 11 can be partially accommodated in the protective groove 2123 formed by the protective structure 2122 and is spaced apart from the protective structure 2122. Thus, the protective structure 2122 can be placed adjacent to the discharge pipe 11 on the forming mold 12, and can promptly heat the molten glass flowing from the discharge pipe 11 to the forming mold 12, thereby improving the fluidity of the molten glass, allowing the molten glass to be fully spread out and improving the forming yield of the glass sheet. In addition, the placement of the protective structure 2122 adjacent to the discharge pipe 11 by the heating mechanism 20 can also space the discharge pipe 11 from the side insulation board 212, providing thermal insulation protection for the discharge pipe 11 and preventing the discharge pipe 11 from being burned through and damaged by high temperature.

[0044] Furthermore, in some embodiments, the length of two opposing side insulation boards 212 is greater than the length of the other two opposing side insulation boards 212. The two longer side insulation boards 212 are spaced apart from and opposite to the heating element 22, and the protective structure 2122 is provided on one of the longer side insulation boards 212. When the heating mechanism 20 is provided on the forming mold 12, the extension direction of the two longer side insulation boards 212 is parallel to the length direction of the heating mechanism 20, and at least a portion of the discharge tube 11 is accommodated within the protective groove 2123. In other words, the heating mechanism 20 is placed horizontally on the forming mold 12, and the length direction of the heating mechanism 20 is perpendicular to the pulling direction of the glass sheet by the pulling mechanism 13. This allows the heating mechanism 20 to heat the molten glass material and fully spread it, while also reducing the space occupied by the heating mechanism 20. It should be noted that when the heating mechanism 20 is placed on the forming mold 12, the heating mechanism 20 is spaced apart from the surface of the glass liquid, that is, the bottom insulation board 211 is spaced apart from the glass liquid. The heating mechanism 20 conducts heat to the glass liquid through the air to heat the glass liquid, which is beneficial to avoid the heating mechanism 20 scratching the surface of the glass liquid and affecting the surface quality of the formed glass plate.

[0045] In some embodiments, the materials of the heating element 22 and the heat-insulating element 21 include but are not limited to heat-resistant metals such as stainless steel, and can also be any other suitable heat-resistant materials. The length of the heating element 22 can be 250mm-300mm, the width can be 50mm-80mm, and the height can be 50mm-80mm. The length direction of the heating element 22 can be parallel to the length direction of the heating mechanism 20. The length of the support structure 24, that is, the dimension of the support structure 24 in the height direction of the heating mechanism 20 is 10mm-15mm. The length of the heat-insulating element 21 is 350mm-500mm, the width is 200mm-300mm, and the height is 50mm-100mm. The thickness of the heat-insulating element 21, that is, the thickness of the bottom insulation board 211 and each side insulation board 212 is 2mm-3mm. The protective structure 2122 can be a semicircular plate-shaped structure with a radius of 30mm-50mm. Reference Figure 4 and Figure 5 As shown, in some embodiments, a protective structure 2122 may protrude from the end of the partition body 2121 away from the bottom insulation plate 211 to provide thermal insulation protection for the longer portion of the discharge tube 11, preventing damage to the discharge tube 11 due to high temperatures. The length of the protective structure 2122, that is, the height dimension of the protective structure 2122 in the heating mechanism 20, is 80 mm to 150 mm.
