Technical Field

[0001] This utility model belongs to the field of glass melting furnaces. Specifically, this utility model relates to a clarification and diversion structure for a glass melting furnace. Background Technology

[0002] A glass melting furnace is a thermal equipment used in glass manufacturing to melt glass batches. Its function is to melt and clarify powdered and crushed glass according to the glass composition at high temperature in the furnace to form molten glass that meets the forming requirements. In existing multi-line glass furnaces, after the molten glass is clarified in the clarification zone, it enters the passage or working zone through the neck. The following two diversion methods are usually adopted: one is to divert through the horizontal passage, and the other is to draw a branch line from the side of the main working zone. The diversion area of ​​both methods is located after the neck, which means that the temperature and uniformity of the molten glass in the diversion area are close to the parameters required for forming. Due to the different drawing amounts and drawing speeds of the multiple branches, the liquid flow interferes with each other greatly, affecting the subsequent homogenization of the molten glass and the quality and uniformity of high-grade glass products.

Detailed Implementation

[0014] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0015] Figure 1 This is a schematic diagram of the glass melting furnace clarification and diversion structure in an embodiment of this utility model. Figure 1 ; Figure 2 This is a schematic diagram of the glass melting furnace clarification and diversion structure in an embodiment of this utility model. Figure 2 .

[0016] like Figure 1 and Figure 2 As shown, the glass melting furnace clarification and diversion structure provided by this utility model includes a melting zone 10, a clarification zone 20, and a working zone 30. The clarification zone 20 is located between the melting zone 10 and the working zone 30. A diversion unit 40 is provided between the clarification zone 20 and the working zone 30. Powder and crushed glass prepared according to the glass composition are melted at high temperature in the melting zone 10. The molten glass is then passed through the clarification zone 20 to remove air bubbles and improve the uniformity of the molten glass. The molten glass is then diverted to the working zones 30 of each line through the diversion unit 20 to further stabilize the uniformity of the molten glass and provide a continuous and stable molten glass for subsequent lines. The diversion unit 40 can reduce the influence of liquid flow between lines, effectively stabilize the temperature and uniformity of the molten glass in each line, avoid temperature fluctuations affecting the forming quality of subsequent glass, and help improve the quality of glass production to meet the needs of high-grade glass production.

[0017] The diversion unit 40 includes a main line path 41 and a branch line path 42. The working area 30 includes a main line working area 31 and a branch line working area 32. The two ends of the main line path 41 are connected to the clarification zone 20 and the main line working area 31, respectively. The two ends of the branch line path 42 are connected to the clarification zone 20 and the branch line working area 32, respectively. The branch line path 42 and the branch line working area 32 can be configured according to actual production needs, and two branch lines can be drawn from the end of the clarification zone 20, such as... Figure 1 As shown, or by drawing a branch line, such as Figure 2 As shown, this is to meet different glass production needs.

[0018] The main line passage 41 is equipped with a main line neck 43, which is located between the refining zone 20 and the main line working zone 31. The branch line passage 42 is equipped with a branch line neck 44, which is located between the refining zone 20 and the branch line working zone 32. The neck is a narrow channel structure used to separate the refining zone 20 and the working zone 30 to achieve physical and thermal isolation between the refining zone 20 and the working zone 30. The neck is shaped like a "neck" and has a narrow channel, which can prevent high-temperature bubbles and unmelted particles in the refining zone 20 from entering the working zone 30, thus avoiding affecting the purity of the glass melt. It can also suppress heat convection and heat radiation between the refining zone 20 and the working zone 30, ensuring the temperature control accuracy of the working zone 30. It can also adjust the flow rate of the glass melt, allowing the glass melt to have enough time to complete temperature homogenization in the working zone 30. Meanwhile, the positions of the main line bottleneck 43 and the branch line bottleneck 44 are determined according to the temperature characteristics of the glass melting furnace process. The branch line diversion position is set before the main line bottleneck 43 and the branch line bottleneck 44. That is, after diverting from both sides of the rear end of the refining zone 20 through the branch line passage 42, it passes through the bottleneck. The branch line passage opening is located before the main line bottleneck 43. Here, the glass temperature is high and the glass melt viscosity is low, so the influence of the branch line and the main line liquid flow is small. The main line and the branch line each have independent bottlenecks and working areas 30, minimizing the influence of liquid flow between the lines, improving glass quality, and meeting the needs of producing high-grade glass.

[0019] The main line passage 41 is equipped with a main line deep water tank 411, located at the main line bottleneck 43. A main line agitator 412 is also installed on the main line passage 41, located on the side of the main line deep water tank 411 closest to the main line working area 31. The branch line passage 42 is equipped with a branch line deep water tank 421, located at the branch line bottleneck 44. A branch line agitator 422 is also installed on the branch line passage 42, located on the side of the branch line deep water tank 421 closest to the branch line working area 32. The deep water tanks are typically welded from high-quality rectangular seamless steel pipes. The glass separator, installed at the bottleneck and immersed in the molten glass, reduces the backflow of molten glass in the working zone 30, slows the forward speed of the molten glass at the outlet of the refining zone 20, allowing the molten glass to remain in the refining zone 20 for a longer time, thus improving the refining effect. It also lowers the temperature of the molten glass in the bottleneck and working zone 30, helping to create a low-temperature environment suitable for forming. Furthermore, it intercepts impurities to improve purity, blocking scum and incompletely melted powder from the surface of the refining zone 20, ensuring that the molten glass flowing into the cooling section is of higher quality in the depth direction, reducing the impact of impurities on the quality of subsequent formed glass. The agitator is used to enhance the uniformity of the molten glass, accelerate the removal of bubbles, and further stabilize the temperature and uniformity of the molten glass in each line. The melting zone 10 is equipped with a heat storage chamber 11 on both sides and a combustion system furnace 12 connected to the heat storage chamber 11. The heat storage chamber 11 preheats the combustion air. The preheated combustion air is sent into the combustion system furnace 12 and mixed with fuel (coal gas, heavy oil, etc.) for complete combustion, producing a high-temperature flame of 1500°C to 1600°C. The high-temperature flame ejected from the combustion system furnace 12 directly acts on the glass batch material in the melting zone 10, causing it to melt rapidly and form molten glass.

[0020] The glass melting furnace clarification and diversion structure provided by this utility model includes a melting zone 10, a clarification zone 20, and a working zone 30. The clarification zone 20 is located between the melting zone 10 and the working zone 30. A diversion unit 40 is provided between the clarification zone 20 and the working zone 30. Powder and crushed glass prepared according to the glass composition are melted at high temperature in the melting zone 10. The molten glass passes through the clarification zone 20 to remove air bubbles and improve the uniformity of the molten glass. Then, it passes through the diversion unit 20 to divert the molten glass to each line working zone 30, further stabilizing the uniformity of the molten glass and providing a continuous and stable molten glass for subsequent lines. The diversion unit 40 can reduce the influence of liquid flow between lines, effectively stabilize the temperature and uniformity of the molten glass in each line, avoid temperature fluctuations affecting the forming quality of subsequent glass, and help improve the quality of glass production to meet the needs of high-grade glass production.
