Abstract
Description
Technical Field
[0001] This utility model relates to the field of substrate glass manufacturing technology, specifically to a connection structure between a substrate glass furnace and a channel. Background Technology
[0002] The substrate glass furnace melts the added raw materials. After melting, the throat at the bottom of the section transports the molten glass to the channel. After clarification, bubbles are removed, and the mixture is stirred and homogenized, the high-temperature molten glass is then supplied to the forming process.
[0003] The throat is a core piece of equipment in the production of liquid crystal glass substrates. Its main function is to safely and stably transfer the high-temperature molten glass in the substrate glass bath furnace to the channel. The throat operates in the high-temperature environment of the molten glass for a long time, so its stability and reliability play a vital role in the production line.
[0004] In actual production, the throat pipe is installed in the flow hole brick hole at the bottom of the side wall of the furnace. During long-term use, the high-temperature molten glass will erode the pool wall near the flow hole brick hole and the outer wall of the throat pipe, causing gaps to form between the outer wall of the throat pipe and the flow hole brick hole. This results in poor sealing between the outer wall of the throat pipe and the flow hole brick hole, and the high-temperature molten glass will flow out from the gaps. Utility Model Content
[0005] The purpose of this invention is to provide a connection structure between a substrate glass melting furnace and a channel, which can solve the problem of poor sealing between the outer wall of the throat and the brick hole of the flow channel in the prior art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A connection structure between a substrate glass melting furnace and a channel is disclosed. The substrate glass melting furnace includes a furnace body. A flow channel brick hole is opened at the bottom of the rear wall of the furnace body. A throat pipe is fixedly installed in the flow channel brick hole. The other end of the throat pipe is fixedly connected to the channel. A cooling ring assembly is also provided on the outer periphery of the throat pipe.

[0009] As a further embodiment of this utility model: the air cooling ring assembly further includes an upper air cooling ring pipe, which spans across the throat pipe and is connected to the air cooling ring control mechanism.
[0010] As a further embodiment of this utility model: the air cooling ring control mechanism includes a main air duct and three branch air ducts.

[0011] As a further embodiment of this utility model: an air regulating valve, an air filter, and an air pressure gauge are sequentially installed on each of the three air branch pipes. An air bypass pipe is also provided on each of the three air branch pipes. The air bypass pipe is connected in parallel with the air regulating valve and the air filter on the corresponding air branch pipe. An air regulating valve is also installed on the air bypass pipe.

[0029] Please see Figure 1-4 As shown, this embodiment of the invention provides a connection structure between a substrate glass melting furnace and a channel. Please refer to [link / reference]. Figure 1 As shown, the substrate glass melting furnace includes a furnace body 1. A flow channel brick hole is formed at the bottom of the rear wall of the furnace body 1. A feeding port 2 is formed on the side of the furnace body 1 opposite to the flow channel brick hole. A support frame 3 is installed at the bottom of the furnace body 1. A throat pipe 4 is fixedly installed inside the flow channel brick hole, and the other end of the throat pipe 4 is fixedly connected to a channel 5. Molten glass in the furnace body 1 is transported to the channel 5 through the throat pipe 4. A cooling ring assembly is also provided around the throat pipe 4. The cooling ring assembly includes an air cooling ring group and a water cooling ring group, which are spaced apart around the throat pipe 4.
[0030] The high-temperature molten glass flowing into the gap between the outer wall of the throat 4 and the brick hole of the flow channel is rapidly solidified by the air cooling ring group and the water cooling ring group, thereby sealing the gap between the outer wall of the throat 4 and the brick hole of the flow channel. At the same time, it can also reduce the temperature of the furnace pool wall near the throat 4 and reduce the erosion of the furnace pool wall by the molten glass.
[0031] Please see Figure 2 and Figure 3 As shown, the air cooling ring assembly includes a left air cooling ring pipe 7, a right air cooling ring pipe 8, and an air cooling ring control mechanism 25. The left air cooling ring pipe 7 and the right air cooling ring pipe 8 are disposed opposite each other on the outer periphery of the throat pipe 4, and the air cooling ring control mechanism 25 is connected to the left air cooling ring pipe 7 and the right air cooling ring pipe 8 respectively. The air cooling ring assembly also includes an upper air cooling ring pipe 6, which spans across the throat pipe 4 and is connected to the air cooling ring control mechanism 25.
[0032] Please see Figure 4As shown, the air cooling ring control mechanism 25 includes a main air duct 12 and three branch air ducts 13. The three branch air ducts 13 are connected in parallel to the main air duct 12, and the ends of the three branch air ducts 13 away from the main air duct 12 are respectively connected to the left air cooling ring pipe 7, the right air cooling ring pipe 8 and the upper air cooling ring pipe 6 through connecting pipes 11.
[0033] Furthermore, each of the three air branch pipes 13 is sequentially equipped with an air regulating valve 14, an air filter 15, and an air pressure gauge 16. An air bypass pipe 17 is also provided on each of the three air branch pipes 13. The air bypass pipe 17 is connected in parallel with the air regulating valve 14 and the air filter 15 on the corresponding air branch pipe 13. An air regulating valve 14 is also installed on the air bypass pipe 17.
[0034] In operation, high-pressure air enters three branch air pipes 13 from the main air duct 12. The high-pressure air from each branch pipe 13 then flows through its corresponding connecting pipe 11 into the left air cooling ring pipe 7, right air cooling ring pipe 8, and upper air cooling ring pipe 6. During this process, the air pressure can be adjusted via the air regulating valve 14, and the air pressure is displayed on the air pressure gauge 16. The air filter 15 filters the high-pressure air. The air bypass pipe 17 on each branch pipe 13 allows for easy opening of the bypass pipe 17 when cleaning the air filter 15, ensuring uninterrupted air cooling.
[0035] Please see Figure 2 and Figure 3 As shown, the water cooling ring assembly includes a left water cooling ring pipe 9, a right water cooling ring pipe 10, and a water cooling ring control mechanism 26. The left water cooling ring pipe 9 and the right water cooling ring pipe 10 are disposed opposite to each other on the outer periphery of the throat pipe 4, and the water cooling ring control mechanism 26 is connected to the left water cooling ring pipe 9 and the right water cooling ring pipe 10 respectively.
[0036] Please see Figure 4 As shown, the water cooling ring control mechanism 26 includes a main water pipe 18 and two branch water pipes 19. The two branch water pipes 19 are connected in parallel to the main water pipe 18, and the ends of the two branch water pipes 19 away from the main water pipe 18 are respectively connected to the left water cooling ring pipe 9 and the right water cooling ring pipe 10 through connecting pipes 11.
[0037] Furthermore, a water regulating valve 20, a water filter 21, and a water pressure gauge 22 are sequentially installed on each of the two water branch pipes 19. A water bypass pipe 23 is also provided on each of the two water branch pipes 19. The water bypass pipe 23 is connected in parallel with the water regulating valve 20 and the water filter 21 on the corresponding water branch pipe 19. A water regulating valve 20 is also installed on the water bypass pipe 23.
[0038] In use, cooling water enters two branch pipes 19 from the main water pipe 18. Then, the cooling water from the two branch pipes 19 flows through their respective connecting pipes 11 into the left and right water cooling ring pipes 9 and 10, respectively. During this process, the cooling water pressure can be adjusted using the water regulating valve 20, and the pressure is displayed on the water pressure gauge 22. The water filter 21 filters the cooling water. The water bypass pipe 23 on each branch pipe 19 allows for easy opening of the bypass pipe 23 when cleaning the water filter 21, ensuring uninterrupted cooling.
[0039] It should be noted that the throat 4 and channel 5 in this utility model are both double-layer platinum structures. The double-layer platinum structure of the throat 4 increases the thickness of the throat 4, which well ensures the strength of the throat 4. Inside the double-layer platinum channel 5, high-temperature glass liquid is transferred, so that the temperature of the high-temperature glass does not decrease and the fluidity is not affected.
[0040] Please see Figure 3 As shown, an electric heating flange 24 can also be installed around the throat 4 to ensure that the temperature of the flowing glass melt does not drop and the glass melt does not thicken after being powered on.
[0041] The preferred embodiments of this utility model have been described in detail above and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
