Description

[Technical Field]

[0001] FIELD OF THE INVENTION The present invention relates to the field of substrate glass manufacturing, and more particularly to an adjustable heat dissipation device and method for passageway cooling. [Background technology]

[0002] The cooling section is one of the important parts of the passage equipment structure, and its main purpose is to cool the high-quality molten glass uniformly and quickly, so that the molten glass can be cooled to a state that meets the forming process requirements within a limited time. The cooling section can be made of flat tubes according to its special structure and function requirements. (Flat Pipe) The mold structure is designed to improve heat dissipation in the cross section, and the exterior is made of refractory bricks of different materials, allowing the temperature in the area to be reduced quickly and stably.

[0003] The controllable temperature reduction of the cooling section is mainly achieved by a heater installed outside the platinum, which provides low heat output to the high-temperature molten glass inside, allowing the molten glass inside to be cooled at different rates, i.e., as the heater power decreases, the heat dissipation rate of the molten glass increases, and as the heater power increases, the heat dissipation rate of the molten glass decreases.As the production efficiency of glass substrates gradually improves, traditional equipment often has problems with the heat dissipation capacity of molten glass at high flow rates due to the cooling section, even when all other components are sufficient. That is, even if the heating power of the cooling section for that area is reduced to the lowest point, a high heat dissipation level cannot be ensured, and there is a risk that the temperature reduction effect will become uncontrollable due to the power being close to the lower limit.

[0022] The present invention will now be described in more detail with reference to the drawings.

[0023] As shown in the figure, the adjustable heat dissipation device for a passage cooling section of the present invention includes a plurality of flat tubes 1 arranged adjacent to each other inside the cooling section, a heater is installed around the outer ring of the flat tubes 1, side heat insulating structures 3 are installed on both sides of each flat tube 1, and an upper heat insulating structure 5 is installed at the upper end of each flat tube 1; The side heat insulating structure 3 includes a side heat insulating member 31, a side clamping member 32, and a side heat insulating member 33, one surface of the side heat insulating member 33 matches and adheres to the side of the flat tube 1, the other surface of the side heat insulating member 33 adheres to the side heat insulating member 31, and side clamping members 32 are installed on both ends of the side heat insulating member 33, The upper heat insulating structure 5 includes a heat insulating member 51 disposed above the upper ends of the flat tubes 1 , and upper clamping members 52 disposed on both ends of the upper heat insulating member 51 .

[0024] The present invention provides an adjustable heat dissipation device for a passage cooling section, and realizes online adjustment of heat dissipation capacity by designing a component-type disassembled cooling section insulation structure. Specifically, the insulation structure is divided into a side insulation structure 3 installed on the side of both ends of the cooling section flat tube 1 and an upper insulation structure 5 installed on the top of the cooling section flat tube 1. The side insulation structure 3 is made of three components joined together, and the shape of the joined structure matches the side of both ends of the cooling section flat tube 1 to provide close insulation, and can also be disassembled to adjust heat dissipation during heat dissipation. The upper insulation structure 5 is made of two components, and can not only ensure insulation of the top end of the cooling section flat tube 1, but also realize disassembled heat dissipation adjustment. In addition, the side insulation structure 3 and the upper insulation structure 5 are respectively equipped with side clamping members 32 and side clamping members 32 that can be easily clamped by external mechanical members, and when combined, the insulation structure can be disassembled. The advantages of designing a component-type cooling unit insulation structure in this invention are as follows: it satisfies the clamping and fixing function of the overall structure by the external mechanical structure, ensures the basic safety and reliability of the equipment, and enables rapid disassembly of local insulation materials; the heat dissipation level can be adjusted by changing the shape of the insulation structure, and when combined with synchronous power matching adjustment, the heat dissipation capacity of the cooling unit can be improved online, ensuring the safety and reliability of the flow rate improvement and providing important technical support for improving the productivity of the production line.

[0025] As shown in Figure 1, in the present invention, the basic cross-sectional structure of the cooling section includes platinum flat tubes 1, side heaters 2, side insulation structures 3, upper and lower heaters 4, upper insulation structures 5, and support bricks 6 inside the cooling section. Conventional cooling section structures combine a heater surrounding the innermost layer and an insulation structure surrounding the outer layer, with support bricks 6 fixing and clamping the insulation bricks on four sides, and finally, a mechanical structure acting on the support bricks 6 and side insulation structures 3 in the outermost layer, ensuring safe and stable operation of the overall structure.

[0026] The outer layer insulation structure of the present invention is the core part of the present invention, and includes a side insulation structure 3 and an upper insulation structure 5, which are designed with different shapes to meet the sandwiching structure, i.e., the upper insulation structure 5 is a plate-type structure, and the side insulation structure 3 is a U-shaped structure, thereby ensuring that both outer surfaces are flat structures and providing sandwiching surfaces for the mechanical structure.

[0027] The insulation structure and the internal heater module are composed of multiple identical modules butted together in an array, mainly because the cooling section structure is long and it is difficult to directly process the components of a single module. To achieve online removal and installation, as shown in Figure 2, in the case of the side, the actual mechanical clamping structure acts on the area where two modules butt together. Therefore, the present invention designs a split structure for the side insulation structure 3, and in the case of the top, the holding brick 6 directly acts on the area between the adjacent top insulation structure 5.

[0028] Specifically, as shown in Figure 3, the disassembled structure of the side insulation structure 3 is divided into five blocks and mainly consists of three parts: a side outer insulation member 31, a side clamping surface member, and a side inner insulation member 33. The material is the same as that of the flat tube 1, and aluminum insulation material with high thermal conductivity is used. A total of five parts, the above three parts, are joined together to form a complete side U-shaped brick insulation structure for insulating the side area.

[0029] Specifically, as shown in Figure 4, the disassembled structure of the upper insulation structure 5 is divided into a total of three blocks, and mainly consists of two parts: an upper insulation member 51 and an upper clamping member 52, which are made of the same material as the flat tube 1, that is, aluminum material with high thermal conductivity.

[0030] Preferably, both the side heat insulating structure 3 and the upper heat insulating structure 5 use high alumina heat insulating bricks.

[0031] A butt seam remains between the upper clamping members 52 at the upper ends of two adjacent flat tubes 1, and a pressure brick 6 is installed in the butt seam. The pressure brick 6 acts directly on the butt seam area between the two adjacent flat tubes 1 and is used to fix the upper insulation structure 5 at the upper end of the flat tube 1.

[0032] Preferably, the flat tube 1 includes a flat tube upper plate and a flat tube bottom plate, the flat tube upper plate being arch-shaped, the flat tube bottom plate being flat, and both side edges being bent upward and welded to the flat tube upper plate to form the flat tube 1.

[0033] The side inner heat insulating member 33, the side clamping member 32 and the side inner heat insulating member 33 are joined together to form a U-shaped structure, and the radian of the U-shaped structure is consistent with the radian of both sides of the flat tube 1.

[0034] Preferably, adjacent flat tubes 1 are connected by flange welding.

[0035] The present invention further provides a heat dissipation method for an adjustable heat dissipation device for a passage cooling section, by designing an online disassembly method matching the heat dissipation device described in the present invention, realizing online adjustment of the heat dissipation capacity, which includes the following steps:

[0036] Perform primary disassembly for each flat tube 1 one by one. stomachThe primary disassembly includes loosening the side clamping members 32 at both ends of the side internal insulation member 33, then sequentially removing the upper insulation member 51 and the side external insulation member 31 of the flat tube 1, and re-fixing the side clamping members 32 to achieve the primary heat release of the cooling section.

[0037] Furthermore, if the heat dissipation requirements are not met after the primary disassembly, secondary disassembly is performed on each flat tube 1 one by one in sequence, and the secondary disassembly includes loosening the side clamping members 32 at both ends of the side internal insulation members 33, and then removing the side internal insulation members 33 of each flat tube 1 in sequence, thereby realizing secondary heat release of the cooling section.

[0038] The adjustable heat dissipation method described in the present invention is divided into two heat dissipation classes in total, which can respectively meet the heat dissipation capacity requirements under different flow rate requirements, without affecting process stability, etc. Specifically, it includes two disassembly steps, and combined with the design of an insulation structure that allows parts to be disassembled, it can achieve a certain amount of heat release each time a part is disassembled, and combined with the power adjustment of the heater around the flat tube 1 of the cooling section, it can ensure a high level of heat dissipation while avoiding the risk of the heater power being too low and becoming uncontrollable, ensuring the normal functioning of the passage cooling section, and is easy to operate and highly practical.

[0039] The specific steps for carrying out the installation adjustment are as follows:

[0040] In practice, during the initial installation process, the side insulation structure 3 and the upper insulation structure 5 are assembled according to the structure shown in Figure 1, with the side outer insulation member 31 and the side inner insulation member 33 directly in contact with each other, without the need for refractory mortar bonding, and simply clamped to both sides of the outer surface of the side outer insulation member 31 by an external mechanical structure, and the side clamping members 32 are clamped and fixed by a fixed mechanical structure and generally do not disassemble. Similarly, the upper insulation structure 5 acts directly on the upper clamping surface member by the holding bricks 6 to fix the butt seam, and the intermediate upper insulation member 51 can be directly placed on top without the need for clamping, which is the initial construction state.

[0041] Regarding the disassembly process, when the problem of insufficient heat dissipation capacity of the cooling section is encountered, mainly during the production process due to process adjustments such as increasing flow rate, primary disassembly is first carried out, that is, each module of flat tubes in the cooling section is removed one by one, and the upper insulation member 51 and side external insulation member 31 of each flat tube are removed in sequence. To remove the upper part directly, the clamping mechanism for the side external insulation member 31 needs to be loosened, and after the side external insulation member 31 is removed, the clamping mechanism is re-fixed, and up to this point, the heat dissipation improvement achieved by primary disassembly is achieved.

[0042] The secondary decomposition is performed when the heat dissipation requirements cannot be met even after the primary decomposition, by disassembling the side internal insulation member 33 under higher flow conditions. The process is the same as the disassembly method for the side external insulation member 31 described above, that is, the flat tubes 1 in the cooling section are removed one by one, and the side internal insulation member 33 of each flat tube is removed in sequence. The side needs to loosen the clamping mechanism for the side internal insulation member 33, and after the side internal insulation member 33 is removed, the clamping mechanism is re-fixed. Up to this point, the heat dissipation improvement achieved by secondary decomposition is achieved.

[0043] The adjustable heat dissipation device for passage cooling section designed according to the present invention can be combined with heat dissipation removal schemes implemented according to different flow rates to achieve equivalent heat dissipation matching, and the above process can be reversed, i.e., the heat dissipation can be reduced to match the flow rate reduction process. In practical use, the above primary decomposition can increase the heat dissipation by 6%, and the secondary decomposition can increase the heat dissipation by 14%, achieving the flow rate adjustment requirement of 650 kg / h to 800 kg / h.

[0044] It should be noted that the above examples are only used to explain the technical solutions of the present invention and are not intended to limit the same. The present invention has been described in detail with reference to the above examples, but it should be understood that those skilled in the art can make modifications and equivalent substitutions to the specific embodiments of the present invention, and any modifications and equivalent substitutions that do not deviate from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
