Description

Technical Field

[0001] The present invention relates to the technical field of glass production, and in particular to a device for producing colored glass using one kiln and two lines and a method for using the device. Background Art

[0002] In the glass manufacturing industry, evolving market demands are placing higher demands on glass production technology. On the one hand, large-tonnage float glass furnaces are attracting attention for their ability to improve heat utilization, making energy conservation a key trend in the industry. On the other hand, market demand for increasingly diverse glass types is increasing. Traditional one-furnace-one-line production methods, with their limited range of products, struggle to meet the rapidly evolving market demands for differentiated competition. Consequently, the one-furnace-two-line glass melting furnace design has emerged. This approach balances energy conservation and consumption reduction with the need to produce a wide variety of products, and is increasingly favored by glass manufacturers.

[0003] However, the existing one-kiln two-line technology is mainly used to produce ordinary white and ultra-white glass, and it still has many shortcomings in the production of colored glass: First, the production of colored glass has higher requirements for glass liquid convection and temperature control, and the existing one-kiln two-line technology is prone to weak glass liquid convection. Insufficient glass liquid convection will lead to uneven mixing of internal components of the glass liquid, thereby affecting the color consistency and quality stability of the colored glass; Second, the glass liquid has a large temperature drop when flowing in the existing one-kiln two-line melting furnace. Excessive temperature drop may cause the glass liquid to have too low a temperature before it is fully formed, thereby affecting the forming effect of the glass and increasing the defective rate; Third, when different colors of glass need to be produced, under the existing one-kiln two-line technology, the color change process of the glass liquid is cumbersome and time-consuming; In addition, in the process of using the existing one-kiln two-line technology to produce colored glass, the glass liquid is also prone to crystallization, causing it to lose transparency, seriously affecting product quality.

[0028] like Figure 1-5 As shown, a preferred embodiment of a one-kiln two-line device for producing colored glass is shown, comprising: a melting section 1, a neck 2, a transverse passage 3, a cooling section 4, a heat storage chamber 5, a small furnace 6 and a melting zone bubbling device 110.

Furthermore, the spacing is preferably set to 3.8-4.5m.

[0030] Furthermore, as a preferred embodiment, two rows of melting zone bubbling devices 110 are provided, one row of melting zone bubbling devices 110 is close to the center line of the fifth small furnace 65, and the other row of melting zone bubbling devices 110 is close to the center line of the seventh small furnace 67.

[0032] Furthermore, as a preferred embodiment, the melting zone bubbling device 110 is a water-cooled bubbling device. Furthermore, by providing two rows of melting zone bubbling devices 110, convection circulation of the molten glass in the melting zone 11 is promoted, and the various components in the molten glass are uniformly mixed, thereby improving the melting quality of the glass and significantly shortening the color change time of the molten glass.

[0033] Furthermore, as a preferred embodiment, a clarification zone color adjustment and bubbling device 120 is further included. The clarification zone color adjustment and bubbling device 120 is arranged on a side of the clarification zone 12 close to the neck 2 .

Furthermore, the clarification zone color-adjusting bubbling devices 120 not only help increase the convection speed of the molten glass, but also promote the discharge of bubbles and impurities in the molten glass, while promoting the uniform distribution of colorants in the molten glass, thereby improving the clarification and homogenization quality of the colored glass.

[0035] Furthermore, as a preferred embodiment, it further comprises a transverse passage color mixing and bubbling device 300, which is arranged in the transverse passage 3.

Furthermore, the transverse passage color-adjusting bubbling devices 300 and the cooling section color-adjusting bubbling devices 400 can enhance the convection effect of the molten glass, thereby improving the homogenization effect of the colored glass and effectively preventing devitrification of the colored glass due to an excessively thick bottom immobile layer during homogenization.

[0038] Furthermore, as a preferred embodiment, FEF electric heating devices are installed on both sides of the breast wall of the branch cooling section 42. Furthermore, as the molten glass flows through the branch cooling section 42, the FEF electric heating devices can monitor the temperature of the molten glass in real time and add heat as needed to ensure that the temperature of the molten glass in the branch cooling section 42 remains within an appropriate range, preventing the molten glass from experiencing an excessive temperature drop that could affect the molding effect, thereby facilitating temperature controllability within the branch cooling section 42.

The horizontal passage color adjusting and bubbling device 300 in the horizontal passage 3 generates bubbles to mix with the glass liquid. The glass liquid is then diverted into the main line cooling section 41 and the branch line cooling section 42. At this time, the cooling section color adjusting and bubbling device 400 generates bubbles to mix with the glass liquid. The glass liquid forms glass after cooling.
