[0033] In combination Figure 1 And Figure 2 , the application provides a float glass melting production line. The float glass melting production line comprises a melting furnace 100 and a heat preservation assembly 200, the melting furnace 100 is used for heating raw materials, the heat preservation assembly 200 is located on the left and right sides of the melting furnace 100, the heat preservation assembly 200 comprises a first rigid piece 210, a heat preservation curtain 220 and a second rigid piece 230, the first rigid piece 210 is installed on the top of the melting furnace 100, the top end of the heat preservation curtain 220 is connected to the first rigid piece 210, the bottom end of the heat preservation curtain 220 is connected with the second rigid piece 230, and the second rigid piece 230 is located at the bottom of the melting furnace 100.

The heat preservation curtain 220 can effectively slow down the high-temperature heat loss of the melting furnace 100, reduce the heating energy that must be continuously input to maintain the required temperature in the melting furnace 100, reduce the energy consumption, and reduce the energy waste caused by heat loss. It has a direct and positive impact on improving the energy efficiency of the float glass melting production line and reducing the operating cost, and solves the technical problem of the existing float glass melting production line that requires a large amount of heating energy.
[0035] In addition, the heat preservation curtain 220 can also reduce the dust flying in the raw material pool; in addition, the heat preservation curtain 220 separates the outside from the raw material pool and the raw material inlet of the melting furnace 100, avoiding the pollution of the raw material.
[0036] In some embodiments, in combination with Figure 1 and Figure 2 , the heat preservation curtain 220 is a high-temperature resistant fiber cloth curtain. The high-temperature resistant fiber cloth curtain can withstand extremely high temperature, is not easy to burn, and can maintain good mechanical properties in a high-temperature environment, ensuring the stability and durability of the heat preservation curtain 220.
[0037] In some embodiments, in combination with Figure 1 and Figure 2 , the heat preservation curtain 220 is a flexible curtain. The flexible curtain can closely fit the contour of the melting furnace 100, reducing heat loss from the gap. The flexible curtain can adapt to melting furnaces 100 of different shapes and sizes, without the need to customize specific heat preservation structures for each melting furnace 100, which helps to reduce production costs and improve the flexibility of the production line. Compared with rigid heat preservation materials, the flexible curtain can better absorb and disperse thermal stress, reducing material deformation or damage caused by temperature changes.
[0038] In some embodiments, in combination with Figure 1 and Figure 2 , the top end of the heat preservation curtain 220 is sewn with a first sleeve hole 221, and the first rigid member 210 is arranged in the first sleeve hole 221, improving the position stability between the heat preservation curtain 220 and the first rigid member 210, ensuring the position stability of the heat preservation curtain 220 in the width direction Y and the height direction Z, and being supported on the first rigid member 210 in the length direction X, ensuring the stable suspension of the heat preservation curtain 220 on the top of the melting furnace 100, reducing the shaking of the heat preservation curtain 220 caused by wind, temperature changes or other external factors, and ensuring the stability of its position and the durability of the heat preservation effect.
[0039] In some embodiments, in combination with Figure 1 and Figure 2The bottom end of the heat preservation curtain 220 is sewn with a second sleeve hole 222, and a second rigid member 230 is arranged in the second sleeve hole 222, which further enhances the stability of the heat preservation curtain 220 at the bottom of the smelting furnace 100, effectively prevents the heat preservation curtain 220 from shaking due to wind, vibration or temperature change and other factors, and ensures the durability and reliability of the heat preservation effect. The installation mode of sewing the second sleeve hole 222 and inserting the second rigid member 230 simplifies the installation process of the heat preservation curtain 220, and also facilitates the future disassembly and replacement.
[0040] In one embodiment, the first rigid member 210 is a high-temperature-resistant stainless steel rod.
[0041] In one embodiment, the second rigid member 230 is a high-temperature-resistant stainless steel rod.
[0042] In some embodiments, in combination Figure 1 and Figure 2 The heat preservation curtain 220 is provided with an observation window, and the heat preservation curtain 220 is connected with an opening and closing piece 240, which can open or close the observation window. The observation window allows the staff to directly observe the internal conditions of the smelting furnace 100 without disassembling the entire heat preservation curtain 220. Opening the observation window using the opening and closing piece 240 can significantly reduce heat loss.
[0043] In one of the embodiments, the opening and closing piece 240 is connected with the edge of the observation window through a zipper. The zipper connection allows the opening and closing piece 240 to easily open or close the observation window without complex operations or tools. The tight structure of the zipper ensures good sealing between the opening and closing piece 240 and the edge of the observation window, which helps to prevent heat loss from the gap and maintain the temperature stability inside the smelting furnace 100.
[0044] Optionally, the zipper is made of high-temperature-resistant stainless steel.
[0045] In one of the embodiments, the material of the opening and closing piece 240 is the same as that of the heat preservation curtain 220. The opening and closing piece 240 and the heat preservation curtain 220 have consistent heat conduction performance. When the opening and closing piece 240 is closed, the temperature distribution around the observation window remains uniform, reducing heat loss caused by material differences. When the opening and closing piece 240 and the heat preservation curtain 220 adopt the same material, the difference in thermal stress between them is reduced, which helps to reduce deformation or damage caused by the difference in thermal stress.
[0046] In one of the embodiments, in combination Figures 1 to 3, each side of the smelting furnace 100 comprises a plurality of heat preservation assemblies 200 arranged in sequence along the length direction X, and each side of the smelting furnace 100 is provided with a connecting sleeve rod 110 located between two adjacent heat preservation assemblies 200, and the float glass smelting production line further comprises a splicing structure 300, the splicing structure 300 comprises a splicing assembly 310 and a splicing plate 320, one end of the splicing assembly 310 is connected to the middle part of the splicing plate 320, the other end of the splicing assembly 310 is provided with a first clamping piece 331 and a second clamping piece 332, one side of the second clamping piece 332 is rotatably installed on one side of the first clamping piece 331, the other side of the second clamping piece 332 is detachably installed on the other side of the first clamping piece 331, the first clamping piece 331 and the second clamping piece 332 enclose a clamping hole 333 for sleeving the connecting sleeve rod 110, and both ends of the splicing plate 320 are connected with the first rigid pieces 210 of the two adjacent heat preservation assemblies 200.
[0047] The design of the splicing structure 300 makes the connection between the heat preservation assemblies 200 more flexible and convenient, which is beneficial to reduce the length requirement of the heat preservation assemblies 200, and the heat preservation of the smelting furnace 100 of different length sizes can be satisfied through splicing without customized design.
[0048] Compared with the traditional method, that is, using a non-openable lifting ring to sleeve the connecting sleeve rod 110 from one end, then moving to a predetermined position along the length direction of the rod, and then lifting the heat preservation assembly 200 for fixation, the present application adopts a more efficient and convenient fixation mode. Specifically, the heat preservation assembly 200 is first connected with the first rigid pieces 210 on both sides through the splicing plate 320. Then, by the opening and closing design of the first clamping piece 331 and the second clamping piece 332, the side of the second clamping piece 332 is easily rotated around the side of the first clamping piece 331, so that the clamping hole 333 is conveniently opened, and the splicing structure 300 can be efficiently sleeved into the middle position of the connecting sleeve rod 110. After the sleeving is completed, only the second clamping piece 332 needs to be reversely rotated to close the clamping hole 333, and the other side of the second clamping piece 332 is firmly connected with the other side of the first clamping piece 331, so that the fixation of the connecting sleeve rod 110 is completed. The whole lifting process is simple and fast, which not only greatly reduces the lifting difficulty, but also significantly improves the lifting efficiency.
[0049] Optionally, the end of the connecting sleeve rod 110 is provided with a limiting piece, and the outer diameter of the limiting piece is greater than the hole diameter of the clamping hole 333, so as to avoid the splicing structure 300 from falling off.
[0050] Specifically, the splicing assembly 310 and the splicing plate 320 can be fixedly connected in a manner of fastener connection, clamping, sleeving, interference fit, welding, etc., which is not limited herein.
[0051] In some embodiments, in combinationFigure 2 and Figure 3 A clamping fastener 334 is used to achieve detachable connection between the other side of the second clamping piece 332 and the other side of the first clamping piece 331. The clamping fastener 334 is threaded into the second clamping piece 332 and the first clamping piece 331, ensuring a stable connection between the two. This connection method is not only easy to operate, but also quick and efficient to assemble and disassemble, effectively reducing the difficulty of disassembly and improving work efficiency.
[0052] It is worth noting that the embodiments of the present application are not limited to using the clamping fastener 334 as a connection method. In other embodiments, detachable clamping, detachable locking and other diversified fixed connection methods can be considered. These methods can also achieve stable connection between the second clamping piece 332 and the first clamping piece 331, and the assembly and disassembly process is also simple and quick. Therefore, we do not make specific limitations on the connection method, but choose the most suitable connection method according to actual needs.
[0053] In one embodiment, in combination with Figure 2 and Figure 3 The splicing assembly 310 includes a sleeve 311 and a telescopic shaft 312. The sleeve 311 is connected to the middle part of the splicing plate 320, and the telescopic shaft 312 is telescopically connected to the sleeve 311 in the height direction Z, and the end of the telescopic shaft 312 away from the splicing plate 320 is connected with the first clamping piece 331. The telescopic shaft 312 can be adjusted in position in the sleeve 311 in the height direction Z, which is beneficial to flexibly adjusting the overall height of the splicing assembly 310 according to actual needs. This flexibility makes the splicing assembly 310 better adapt to the connection sleeve rod 110 of different heights and positions, ensuring the accuracy and stability of the connection.
[0054] In addition, the staff can adjust the height of the telescopic shaft 312 according to actual needs, and then easily sleeve the first clamping piece 331 and the second clamping piece 332 onto the connection sleeve rod 110, while meeting the height installation requirements of the thermal curtain 220 through the adjustment of the telescopic shaft 312 in the height direction Z. This design reduces the complexity and workload in the installation process, and improves the work efficiency.
[0055] Specifically, one of the sleeve 311 and the telescopic shaft 312 has a plurality of clamping holes spaced apart in the height direction Z, and the other of the sleeve 311 and the telescopic shaft 312 has a resilient clamping pin, which can be clamped in any one of the clamping holes to achieve height adjustment of the telescopic shaft 312.
[0056] Specifically, one of the sleeve 311 and the telescopic shaft 312 has a plurality of clamping blocks distributed along the height direction Z, and the other has a plurality of clamping slots, and the clamping blocks can be clamped in any one of the clamping slots to achieve height adjustment of the telescopic shaft 312.
[0057] In some embodiments, in combination with Figure 1 、 Figure 2 and Figure 4 , one end of the second rigid piece 230 is provided with a connecting block 231, and the other end of the second rigid piece 230 is provided with a connecting hole 232. In adjacent two heat preservation assemblies 200, the connecting block 231 of one of the second rigid pieces 230 is inserted into the connecting hole 232 of the other second rigid piece 230, facilitating quick assembly and disassembly between the adjacent two second rigid pieces 230, realizing tight connection, and facilitating splicing of the bottom ends of the two heat preservation assemblies 200.
