Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass melting furnaces, in particular to a novel heat-insulating structure of a float glass melting furnace. Background Art
[0002] A float glass furnace is a high-temperature device used to produce float glass. Float glass is a flat glass made by floating on molten glass and then cooling it to form a shape. The furnace is a key equipment in the production process of float glass. It is mainly used to heat raw materials (such as quartz sand, soda ash, limestone, dolomite, etc.) to a high temperature state to melt them and form glass liquid. The insulation structure of the float glass furnace is an important part to ensure the efficient operation of the furnace and extend its service life. Its main function is to reduce heat loss, improve energy efficiency, and protect the outer shell of the furnace from high temperature damage. In the prior art, due to the large volume of the furnace, it is difficult to cover all surfaces of the furnace with a whole piece of insulation material at one time. Therefore, the common furnace insulation layer is mostly formed by paving many small pieces of insulation materials neatly, but the workload is large when paving, and it cannot be paved quickly, resulting in a long construction period. Utility Model Content
[0003] The utility model provides a novel heat-insulating structure of a float glass melting furnace, which solves the above-mentioned technical problems.
[0004] The utility model solves the above-mentioned technical problems as follows:
[0005] A new type of thermal insulation structure for a float glass melting furnace comprises a bottom plate, an outer shell, a pressure plate and a cross beam, wherein a plurality of cross beams are provided, a pressure plate is installed between the cross beams, a bottom plate is installed between the cross beams via a pressure plate limiter, pressure strips are provided on both sides of the bottom plate, an outer shell is provided on the bottom plate, a first thermal insulation cotton is installed in the outer shell, a barb is provided on the outer surface of the outer shell, and a second thermal insulation cotton is clamped above the pressure plate between the outer shells via a barb limiter.
[0006] On the basis of the above technical solution, the present invention can also be improved as follows.
[0007] Furthermore, the crossbeam is fixed to the outer surface of the glass melting furnace by fasteners or welding.
[0008] The beneficial effects of adopting the above further scheme are:
[0009] As part of the supporting structure, the crossbeam is firmly fixed to the outer surface of the glass melting furnace by fasteners or welding, which can effectively support and fix the entire insulation structure. This stable connection method ensures that the melting furnace structure will not loosen or move under high temperature and working pressure, improving safety and stability.
[0010] Furthermore, straps are provided at both ends of the pressure plate, bolts are installed on the straps, and both ends of the pressure plate are connected and fixed to the crossbeam through the straps and the bolts.
[0011] The beneficial effects of adopting the above further scheme are:
[0012] Bolts are installed on the slats, and the position and tightness of the pressure plate can be adjusted by adjusting the tightness of the bolts. This design allows the tightness of the structure to be flexibly adjusted during installation and maintenance, ensuring the stability and effectiveness of the overall insulation structure.
[0013] Furthermore, a window is provided on the shell to facilitate adjustment of the first thermal insulation cotton through the window after the first thermal insulation cotton is installed in the shell.
[0014] The beneficial effects of adopting the above further scheme are:
[0015] The window design makes it more convenient to install the first insulation cotton. Workers can directly adjust and arrange the first insulation cotton through the window. The existence of the window makes the adjustment process more precise and accurate, ensuring that the insulation cotton is arranged tightly and evenly, improving the insulation effect and the performance stability of the overall structure, saving time and labor costs.
[0016] Furthermore, the pressing plate is T-shaped, the bottom plate and the pressure strip form a convex shape, and the bottom plate is limited by the mutual clamping connection between the pressure strip and the pressing plate.
[0017] The beneficial effects of adopting the above further scheme are:
[0018] The pressure plate is T-shaped, and the bottom plate and the pressure strip form a convex shape. This structural design can ensure the close connection and precise positioning between the bottom plate and the pressure plate. The clamping of the pressure strip and the pressure plate effectively prevents structural displacement or distortion under high temperature and working pressure, ensuring the stability and safety of the overall insulation structure. The optimized design of the convex structure effectively reduces the occurrence of thermal bridge effect. The thermal bridge effect will cause heat to be quickly transferred to other parts of the structure, increasing energy loss and instability of operating temperature, while this design helps to maintain the stability of the internal temperature and improve the overall efficiency and working stability of the melting furnace.
[0019] Furthermore, the shell is evenly distributed between the pressure plate and the crossbeam.
[0020] The beneficial effects of adopting the above further scheme are:
[0021] During installation, the evenly distributed shell can quickly and accurately cover the pressure plate and the crossbeam. This uniformity helps to reduce heat loss and the formation of temperature gradients, and improves the overall insulation effect of the glass melting furnace. The evenly distributed shell design can effectively reduce energy consumption. The improvement of thermal insulation effect and enhanced temperature stability help reduce energy consumption during the operation of the melting furnace, saving production costs and environmental resources.
[0022] The beneficial effects of the utility model are:
[0023] The first heat-insulating cotton is installed inside the shell, and an effective heat-insulating layer is formed between the shell and the pressing plate through the barbs and the second heat-insulating cotton. This design effectively reduces heat loss, reduces energy consumption, and improves the energy efficiency ratio of the glass melting furnace.
[0024] The crossbeam, pressure plate and bottom plate are firmly connected by fasteners or welding, ensuring the stability and durability of the entire insulation structure in high temperature environments. In particular, the T-shaped design between the bottom plate and the pressure plate and the convex structure of the pressure strip effectively limit and enhance the bearing capacity of the structure, preventing deformation and damage during use.
[0025] The window design on the shell makes the installation and adjustment of the first insulation cotton more convenient, reducing the complexity of the construction process. At the same time, the snap-on design between the shell and the pressure plate not only simplifies the replacement of the second insulation cotton, but also improves the efficiency and convenience of maintenance, reducing downtime and maintenance costs.
[0026] The clamping and limiting design of the pressure strip and the pressure plate effectively reduces the occurrence of thermal bridge effect. The thermal bridge effect will cause heat to be quickly transferred to other parts of the structure, increasing energy loss and instability of operating temperature. This design helps to maintain the stability of the internal temperature and improve the overall efficiency and working stability of the melting furnace.

[0037] Embodiment 1
[0038] A new type of thermal insulation structure for a float glass melting furnace includes a bottom plate 1, an outer shell 4, a pressure plate 6 and a cross beam 10. There are several cross beams 10. The cross beams 10 are fixed to the outer surface of the glass melting furnace by fasteners or welding. As a part of the supporting structure, the cross beam 10 is firmly fixed to the outer surface of the glass melting furnace by fasteners or welding, and can effectively support and fix the entire thermal insulation structure. This stable connection method ensures that the melting furnace structure will not loosen or move under high temperature and working pressure, thereby improving safety and stability. A pressure plate 6 is installed between the cross beams 10. Straps 9 are provided at both ends of the pressure plate 6. Bolts 11 are installed on the straps 9. The two ends of the pressure plate 6 are connected and fixed to the cross beam 10 through the straps 9 and the bolts 11. Bolts 11 are installed on the straps 9. The position and tightness of the pressure plate 6 can be adjusted by adjusting the tightness of the bolts 11. This design allows the structural fastening state to be flexibly adjusted during installation and maintenance, ensuring the stability and effectiveness of the overall thermal insulation structure. A bottom plate 1 is installed between the crossbeams 10 through a pressure plate 6, and pressure strips 2 are provided on both sides of the bottom plate 1. The pressure plate 6 is T-shaped, and the bottom plate 1 and the pressure strip 2 form a convex shape. The bottom plate 1 is limited by the clamping connection between the pressure strip 2 and the pressure plate 6. The pressure plate 6 is T-shaped, and the bottom plate 1 and the pressure strip 2 form a convex shape. This structural design can ensure a tight connection and precise limit between the bottom plate 1 and the pressure plate 6. The clamping connection between the pressure strip 2 and the pressure plate 6 effectively prevents structural displacement or distortion under high temperature and working pressure, ensuring the stability and safety of the overall thermal insulation structure. Through the optimized design of the convex structure, the occurrence of thermal bridge effect is effectively reduced. The thermal bridge effect will cause the heat to be quickly transferred to other parts of the structure, increasing energy loss and instability of the operating temperature. This design helps to maintain the stability of the internal temperature and improve the overall efficiency and working stability of the melting furnace. The bottom plate 1 is provided with a shell 4, which is evenly distributed between the pressure plate 6 and the crossbeam 10. During installation, the evenly distributed shell 4 can quickly and accurately cover between the pressure plate 6 and the crossbeam 10. This uniformity helps to reduce heat loss and the formation of temperature gradients, and improves the overall insulation effect of the glass melting furnace. The design of the evenly distributed shell 4 can effectively reduce energy consumption. The improvement of the insulation effect and the enhancement of the temperature stability help to reduce energy consumption during the operation of the melting furnace, save production costs and environmental resources. The first insulation cotton 3 is installed in the shell 4, and a window 8 is opened on the shell 4, which is convenient for the first insulation cotton 3 to be adjusted through the window 8 after being installed in the shell 4. The design of the window 8 makes it more convenient to install the first insulation cotton 3. Workers can directly adjust and arrange the first thermal insulation cotton 3 through the window 8. The existence of the window 8 makes the adjustment process more precise and accurate, ensuring that the thermal insulation cotton is arranged tightly and evenly, improving the thermal insulation effect and the performance stability of the overall structure, saving time and labor costs, and the outer surface of the shell 4 is provided with a barb 7, and the second thermal insulation cotton 5 is limitedly connected to the shell 4 above the pressure plate 6 through the barb 7.
[0039] A new thermal insulation structure of a float glass melting furnace based on Example 1 is used:
[0040] The first heat-insulating cotton 3 is installed inside the shell 4, and an effective heat-insulating layer is formed between the shell 4 and the pressing plate 6 through the barbs 7 and the second heat-insulating cotton 5. This design effectively reduces heat loss, reduces energy consumption, and improves the energy efficiency ratio of the glass melting furnace.
[0041] The crossbeam 10, the pressure plate 6 and the bottom plate 1 are firmly connected by fasteners or welding, which ensures the stability and durability of the entire insulation structure in a high temperature environment. In particular, the T-shaped design between the bottom plate 1 and the pressure plate 6 and the convex structure of the pressure strip 2 effectively limit and enhance the bearing capacity of the structure, and prevent deformation and damage during use.
[0042] The window 8 on the housing 4 makes the installation and adjustment of the first thermal insulation cotton 3 more convenient, reducing the complexity of the construction process. At the same time, the clamping design between the housing 4 and the pressing plate 6 not only simplifies the replacement of the second thermal insulation cotton 5, but also improves the efficiency and convenience of maintenance, reducing downtime and maintenance costs.
[0043] The clamping and limiting design of the pressure strip 2 and the pressure plate 6 effectively reduces the occurrence of thermal bridge effect. The thermal bridge effect will cause heat to be quickly transferred to other parts of the structure, increasing energy loss and instability of operating temperature, while this design helps to maintain the stability of the internal temperature and improve the overall efficiency and working stability of the melting furnace.
