[0002] In existing float glass manufacturing processes, air is typically introduced into the melting furnace as a combustion-supporting gas to ensure complete fuel combustion.

[0025] To illustrate the technical solutions provided in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0026] Firstly, please refer to Figure 1 This application provides a glass furnace 100 including an annealing furnace 10, a melting furnace 20, a combustion air box 30, and a combustion air blower 40; the annealing furnace 10 has an annealing chamber 11 and a hot air outlet 12 connected to the annealing chamber 11; the melting furnace 20 has a combustion chamber 21 and a hot air inlet 22 connected to the combustion chamber 21; the combustion air box 30 has a pressurizing chamber 33, a first air inlet 31 connected to the pressurizing chamber 33, and a first air outlet 32 ​​connected to the pressurizing chamber 33, the first air outlet 32 ​​being connected to the hot air inlet 22 via a pipeline; the combustion air blower 40 has a second air inlet 41 and a second air outlet 42, the second air inlet 41 being connected to the hot air outlet 12 via a pipeline, and the second air outlet 42 being connected to the first air inlet 31 via a pipeline.

[0027] Melting furnace 20 is the core equipment in glass production. It is responsible for melting raw materials (quartz sand, soda ash, limestone, etc.) into a uniform molten glass at high temperatures and removing impurities and air bubbles from the molten glass. During the melting process, fuel and air are introduced into combustion chamber 21. The fuel is ignited with the help of air, creating a high-temperature environment in combustion chamber 21, thereby melting the raw materials.

[0028] Annealing furnace 10 is used to eliminate internal stress generated during the forming and cooling process of glass products, prevent cracking or deformation, and ensure the mechanical strength and stability of glass products. Understandably, during the annealing process of glass products, a large amount of hot air is generated in annealing chamber 11, which can be transported to combustion chamber 21 by combustion fan 40 to heat the air.

[0029] Specifically, raw materials (quartz sand, soda ash, limestone, etc.) are transported to the combustion chamber 21 of the melting furnace 20. The raw materials are melted into a uniform glass liquid at high temperature. The homogenized glass liquid enters the forming process through the flow hole or overflow port to form glass products. The glass products are then sent to the annealing chamber 11 of the annealing furnace 10, where they are slowly heated to the annealing temperature. Finally, the glass products are cooled to eliminate the internal stress generated during the forming and cooling process.

[0030] The combustion chamber 30 is used to pressurize the hot air to ensure that the hot air is effectively delivered to the combustion chamber 21. Specifically, driven by the combustion blower 40, the hot air enters the pressurization chamber 33 from the hot air outlet 12 and accumulates in the pressurization chamber 33. When the pressure in the pressurization chamber 33 reaches a preset value, the hot air is delivered to the combustion chamber 21 from the first air outlet 32 ​​to heat the air.

[0031] The combustion fan 40 is used to provide the driving force for hot air to flow from the annealing chamber 11 to the combustion chamber 21. The combustion fan 40 can be, but is not limited to, a centrifugal fan, an axial fan, etc.

[0032] The glass furnace 100 provided in this embodiment connects the first air outlet 32 ​​to the hot air inlet 22, the second air inlet 41 to the hot air outlet 12, and the second air outlet 42 to the first air inlet 31. Driven by the combustion fan 40, the hot air in the annealing chamber 11 flows sequentially through the hot air outlet 12, the second air inlet 41, the second air outlet 42, and the first air inlet 31 before entering the pressurization chamber 33. After being pressurized by the pressurization chamber 33, the hot air continues to enter the combustion chamber 21 through the first air outlet 32 ​​and the hot air inlet 22 to heat the air introduced into the combustion chamber 21 from the external environment of the melting furnace 20. In this way, the hot air discharged from the annealing chamber 11 can be recovered to heat the air introduced into the combustion chamber 21, which not only effectively reduces energy consumption but also allows the fuel to burn more completely in the combustion chamber 21, thereby effectively reducing the energy consumption of the glass furnace 100.

[0033] In some embodiments of this application, please refer to Figure 1 The glass furnace 100 also includes a pipe assembly 70, which includes a first air supply pipe 71, a second air supply pipe 72 and a third air supply pipe 73. The first air supply pipe 71 is connected to the hot air outlet 12 and the second air inlet 41. The second air supply pipe 72 is connected to the first air outlet 32 ​​and the hot air inlet 22. The third air supply pipe 73 is connected to the second air outlet 42 and the first air inlet 31.

[0034] By adopting the above technical solution, it is convenient to connect the hot air outlet 12 with the second air inlet 41, the second air outlet 42 with the first air inlet 31, and the first air outlet 32 ​​with the hot air inlet 22.

[0035] In some embodiments of this application, please refer to Figure 1 There are multiple annealing chambers 11 and multiple hot air outlets 12. Each hot air outlet 12 is connected to a corresponding annealing chamber 11. The first air supply pipe 71 includes a first manifold section 711 and multiple first branch sections 712. One end of each first branch section 712 is connected to a corresponding hot air outlet 12. The other end of each first branch section 712 is connected to a first end of the first manifold section 711. The other end of the first manifold section 711 is connected to the second air inlet 41.

[0036] The number of annealing chambers 11 and the number of hot air outlets 12 can be determined according to actual application needs, specifically 2, 3, 4, 5, 6, 7, 8, etc. Understandably, each annealing chamber 11 can independently anneal the glass products.

[0037] One end of each of the multiple first branch pipe sections 712 is connected to a corresponding hot air outlet 12, and the other end of each of the multiple first branch pipe sections 712 is connected to a port of the first manifold section 711. The other end of the first manifold section 711 is connected to the second air inlet 41. That is, the hot air in each annealing chamber 11 enters the corresponding first branch pipe section 712 through the corresponding hot air outlet 12 and then flows into the first manifold section 711 along each first branch pipe section 712, so as to combine the hot air in each annealing chamber 11 and deliver it to the combustion chamber 21.

[0038] By adopting the above technical solution, the hot air in each annealing chamber 11 can be transported to the combustion chamber 21 to heat the air introduced into the combustion chamber 21. This not only further reduces energy consumption, but also allows the fuel to burn more completely in the combustion chamber 21, thereby further reducing the energy consumption of the glass furnace 100.

[0039] In some embodiments of this application, please refer to Figure 1 The glass furnace 100 also includes multiple first valve bodies 80a, which are configured one-to-one with multiple first branch pipe sections 712.

[0040] The first valve body 80a can be used to control the on / off state of the first branch pipe section 712, and can also be used to control the flow area of ​​the first branch pipe section 712 to control the flow rate of hot air. The first valve body 80a can be, but is not limited to, a butterfly valve, a ball valve, a gate valve, a regulating valve, etc. In some embodiments, the first valve body 80a is an electric valve to control the opening and closing of the first valve body 80a.

[0041] In other embodiments of this application, please refer to Figure 1The glass furnace 100 also includes a second valve body 80b, which is disposed on the first manifold section 711.

The glass furnace 100 also includes a second valve body 80b, which is arranged on the first manifold section 711.

[0044] By adopting the above technical solution, the on / off state of the first air supply pipe 71 and the flow rate of hot air in the first air supply pipe 71 can be controlled according to different working conditions, which effectively improves the stability of the glass furnace 100 and further reduces the energy consumption of the glass furnace 100.

[0045] In some embodiments of this application, please refer to Figure 1 The number of combustion chambers 21 and the number of hot air inlets 22 are both multiple. The multiple hot air inlets 22 are connected to the multiple combustion chambers 21 in a one-to-one correspondence.

The other end of the multiple second branch sections 722 is connected to one end of the second manifold section 721. The other end of the second manifold section 721 is connected to the first air outlet 32.

[0046] The number of combustion chambers 21 and the number of hot air inlets 22 can be determined according to actual application needs, specifically 2, 3, 4, 5, 6, 7, 8, etc. Understandably, each combustion chamber 21 can independently melt the raw materials.

[0047] One end of each of the multiple second branch pipe sections 722 is connected to a corresponding hot air inlet 22, and the other end of each of the multiple second branch pipe sections 722 is connected to one end of the second manifold section 721. The other end of the second manifold section 721 is connected to the first air outlet 32. That is, the hot air in the second manifold section 721 is divided into multiple parts and enters the corresponding second branch pipe section 722. After passing through the corresponding hot air inlet 22 along each second branch pipe section 722, it enters the corresponding combustion chamber 21 to heat the air in each combustion chamber 21.

[0048] By adopting the above technical solution, hot air can be supplied to multiple combustion chambers 21 at the same time to heat the air introduced into each combustion chamber 21, further reducing energy consumption and allowing the fuel to burn more fully in each combustion chamber 21, thereby further reducing the energy consumption of the glass furnace 100.

[0049] In some embodiments of this application, please refer to Figure 1 The glass furnace 100 also includes multiple third valve bodies 80c, which are configured one-to-one with multiple second branch pipe sections 722.

[0050] The third valve body 80c can be used to control the on / off state of the second branch pipe section 722, and can also be used to control the flow area of ​​the second branch pipe section 722 to control the flow rate of hot air.

[0055] In some embodiments of this application, please refer to Figure 1 The quantity of hot air outlet 12 is greater than the quantity of hot air inlet 22.
