Description

A liquid flow channel structure with multiple lines in one kiln Technical Field

[0001] The present invention relates to the technical field of float glass production equipment, in particular to a one-kiln multi-line liquid flow channel structure. Background Art

[0002] Currently, most flat glass float production lines, both domestically and internationally, are based on a "one kiln, one line" model, with one kiln connected to a single float tin bath via a single flow channel. Daily production capacity has increased from 150 to 1,200 tons per day. Glass produced ranges in thickness from 1.1 to 22 mm. While daily melting tonnage has increased in glass production, energy consumption per unit of flat glass production has decreased. To reduce energy consumption, many domestic glass manufacturers are opting for large-capacity float glass production lines. However, with this "one kiln, one line" model, thin glass, typically 1.1 to 3 mm, becomes difficult to produce as daily production increases.

[0003] To address this challenge, the "one kiln, two lines" high-tonnage float glass production line was born. The current "one kiln, two lines" float glass production line solution builds on the "one kiln, one line" approach by adding a bypass branch to one side of the kiln's cooling section, extending through this bypass branch to a second parallel cooling section. The two cooling sections are connected to their respective flow channels and their corresponding float tin baths to form a single production line. Typically, the production line directly opposite the center of the kiln is called the "main line," while the line parallel to the kiln's centerline is called the "branch line." In the "one kiln, two lines" float glass production line, the main line has a relatively small tonnage and produces thinner glass. The branch line is often larger in tonnage and produces thicker plate glass.

[0004] This "one kiln, two lines" float glass production line also has major disadvantages:

[0005] 1. Glass quality difference. Due to the limitations of the kiln structure, the glass quality of the main line and branch line is quite different. Generally speaking, the main line glass quality is better than the branch line glass quality.

[0006] 2. High energy consumption. The conventional "one kiln, two lines" has two cooling sections, which consumes more energy than the "one kiln, one line" of the same tonnage.

[0007] 3. Increased use of refractory materials. Compared with the "one kiln, one line" of the same tonnage, the "one kiln, two lines" kiln has two cooling sections, and the investment is about 1.5 times that of the "one kiln, one line" of the same tonnage.

[0008] 4. Cold-rolling renovations are difficult. When converting a "one kiln, one line" system to a "one kiln, two lines" system, the original kiln structure cannot be reused, and additional cross passages and cooling units are added. The existing plant structure is difficult to reuse, requiring expansion.

[0009] 5. There must be a certain difference in tonnage between the main line and the branch line. Generally, the main line's tonnage is much lower than that of the branch line, which is 1.5 to 2 times the main line's tonnage. Flexible tonnage adjustment between the two lines is impossible, and the glass specifications produced are also incompatible.

The glass melt enters the branch line tin bath 2' / 2" from the main line quantity adjustment section 4 through the branch line cross-through section 16, the branch line quantity control section 5' / 5", and the branch line outlet section 6' / 6".

[0038] The present invention relates to a multi-line flow channel structure for a single furnace. The main line flow channel section 4 allows for flexible tonnage changes between the main and branch lines. The tonnage and product specifications of each line can be adjusted at any time according to actual production requirements, resulting in high adaptability. The molten glass from both the branch and main lines flows out of the cooling section 1 of the same glass melting furnace, and the quality of the glass produced by the branch and main lines is the same.

[0039] Preferably, as shown in Figures 1 to 4, each section in the flow channel structure is composed of bottom bricks, pool wall bricks, breast wall bricks, and a cover plate 11. The pool wall bricks are arranged on the bottom bricks, the breast wall bricks are arranged on the pool wall bricks, and the cover plate 11 covers the breast wall bricks.

The water bag 17 is used to reduce the temperature of the molten glass at the mainline inlet section 3. The heating end of the inlet section heating electrode 15 is located in the molten glass, thereby heating the molten glass at the mainline inlet section 3.

[0041] Preferably, as shown in Figures 1 to 4, the main line regulating section 4 is provided with a plurality of rotating gate plates 9, a main line regulating section heating hole 13 is opened on the pool wall bricks at the main line regulating section 4, and a main line regulating section unloading hole 7 is opened on the bottom bricks at the main line regulating section 4; a natural gas spray gun 18 or a spatial silicon carbon rod 19 is provided in the main line regulating section heating hole 13, which is used to adjust the temperature of the glass melt at the main line regulating section 4 and change the viscosity of the glass melt at the main line regulating section 4. At the same time, under the action of the rotating gate plate 9, the glass melt at the main line regulating section 4 is homogenized to improve the quality of the glass melt.

[0042] Furthermore, a main line regulating section discharge hole 7 is provided, which can periodically discharge the glass melt with poor quality at the bottom of the glass melt.

[0043] Furthermore, in this embodiment, a driving source is provided, which is in transmission connection with the rotating gate plate 9 , and the rotation direction and rotation speed of the rotating gate plate 9 can be adjusted.

[0044] Furthermore, the one kiln multiple lines of the present application has two cases: one branch line and two branch lines, which are as follows:

[0045] 1. An embodiment with one branch line (one kiln and two lines); in this embodiment, the main line flow regulating section 4 has three rotary gates 9, as shown in FIG1 , namely rotary gates a, b, and c. When it is necessary to increase the main line flow and reduce the branch line flow, the a rotary gate 9 rotates clockwise and increases the speed; the b rotary gate 9 rotates counterclockwise, and the speed is the same as the speed of the a rotary gate 9; the c rotary gate 9 rotates clockwise, and the speed is lower than the speed of the a rotary gate 9. When it is necessary to reduce the main line flow and increase the branch line flow, the c rotary gate 9 rotates counterclockwise and increases the speed; the b rotary gate 9 rotates clockwise, and the speed is the same as the speed of the c rotary gate 9; the a rotary gate 9 rotates clockwise, and the speed is lower than the speed of the c rotary gate 9.

[0046] 2. An embodiment with two branches (one kiln and three lines), the branches are 1# branch line and 2# branch line (the parts marked with ' in the embodiment are parts of 1# branch line, and the parts marked with " are parts of 2# branch line); the main line flow regulating section 4 in this embodiment has four rotating gates 9, as shown in Figure 2, namely rotating gates a, b, c, and d. When it is necessary to increase the flow of the main line and reduce the flow of the 1# branch line and the 2# branch line, the rotating gate 9 a rotates clockwise and increases the speed; the rotating gate 9 b rotates clockwise and the speed is the same as the main line flow. The speed of rotating gate plate a is the same; rotating gate plate 9 d rotates counterclockwise and increases; rotating gate plate c rotates counterclockwise at the same speed as rotating gate plate 9 d.

[0047] Preferably, as shown in Figures 1 to 3, the main line control section 5 is provided with a main line control section gate 10 that can be raised and lowered. A main line control section operation hole 12 is opened on the breast wall brick at the main line control section 5. A water bag 17 is inserted into the main line control section operation hole 12. A main line control section heating electrode is provided on the pool wall brick at the main line control section 5 (the main line control section heating electrode is the same as the inlet section heating electrode 15, not marked in Figure 3); the water bag 17 in the main line control section operation hole 12 cooperates with the main line control section heating electrode to adjust the temperature of the molten glass at the main line control section 5. In this embodiment, by controlling the height of the main line control section gate 10, the amount of molten glass at the main line outlet section 6 can be finely controlled. By adjusting the depth of the water bag 17 and cooperating with the main line control section heating electrode, the temperature of the molten glass at the main line control section 5 can be controlled.

[0048] Preferably, as shown in FIG3 , a mainline gas seal hole 14 is provided at the mainline outlet section 6 , through which a protective gas is introduced. In this embodiment, the protective gas is used to isolate the atmosphere from the flow channel entering the mainline tin bath 2 , thereby reducing the volatilization and condensation of the molten glass and minimizing the impact of the external atmosphere on the mainline tin bath 2 .

[0049] Preferably, as shown in Figure 4, the branch line cross-section 16 is provided with a branch line thermocouple 8', a branch line cross-section unloading hole 7' is opened on the bottom brick at the branch line cross-section 16, a branch line cross-section heating hole 13' is opened on the breast wall brick at the branch line cross-section 16, and a branch line cross-section heating electrode is provided in the branch line cross-section heating hole 13' (the branch line cross-section heating electrode is the same as the main line control section heating electrode, not marked in the drawing), which is used to adjust the temperature of the molten glass at the branch line cross-section 16.

[0050] Furthermore, in this embodiment, the temperature of the molten glass is adjusted by the branch line thermocouple 8' and the branch line cross-section heating electrode so that the viscosity and temperature of the molten glass meet the requirements for entering the branch line control section 5' / 5". Adjusting to an appropriate temperature can enable the spacing between the main line and the branch line to reach a range of 15-50 meters, which is far greater than the spacing range of the "one kiln two lines" in the prior art. In addition, the cross-sectional area of ​​the branch line cross-section 16 is much smaller than the cross-sectional area of ​​the cooling section 1 of the glass melting furnace. Therefore, it will also save more refractory materials than the "one kiln two lines" in the prior art. The spacing between the main line and the branch line can be customized according to the specific cold repair line.

[0051] In this embodiment, the branch line cross-section discharge hole 7' is provided to periodically discharge the glass melt of poor quality at the bottom. The branch line thermocouple 8' is used to measure the temperature of the glass melt entering the branch line control section 5' / 5" of the branch line cross-section 16.

[0052] Preferably, as shown in FIG2 , the branch line control section 5' / 5" is provided with a liftable branch line control section gate plate 10' / 10", a branch line control section operation hole is opened on the breast wall brick at the branch line control section 5' / 5", a water bag 17 is passed through the branch line control section operation hole, and a branch line control section heating electrode is provided on the pool wall brick at the branch line control section 5' / 5"; the water bag 17 in the branch line control section operation hole cooperates with the branch line control section heating electrode to adjust the glass melt temperature at the branch line control section 5' / 5". The branch line control section gate plate 10' / 10" finely controls the amount of glass melt entering the branch line outlet section 6' / 6" through the lifting action; the water bag 17 in the branch line control section operation hole is adjustable in depth, and cooperates with the branch line control section heating electrode to adjust the temperature of the glass melt at the branch line control section 5' / 5".

[0053] Preferably, as shown in FIG2 , a branch line air sealing hole is provided at the branch line outlet section 6' / 6" (the branch line air sealing hole is not shown), and a protective gas is introduced into the branch line air sealing hole. In this embodiment, the protective gas is used to isolate the atmosphere from the flow channel entering the branch line tin bath 2' / 2", reduce the volatile condensation of the glass melt, reduce the influence of the external atmosphere on the branch line tin bath 2' / 2", and reduce the influence of the external atmosphere on the branch line tin bath 2' / 2".

[0054] The present invention relates to a one-kiln multi-line liquid flow channel structure, the inlet of which is connected to the cooling part 1 of the glass melting furnace, and is provided with a main line quantity regulating section 4, which can realize the regulation of the amount of molten glass in the main line and the branch line, and the tonnage between the main line and the branch line can be flexibly adjusted. A main line quantity control section gate plate 10 and a branch line quantity control section gate plate 10' / 10" are provided, which can finely control the amount of molten glass entering the main line outlet section 6 and the branch line outlet section 6' / 6". A main line air sealing hole 14 is provided on the main line outlet section 6, and a branch line air sealing hole is provided on the branch line outlet section 6' / 6". Both the main line air sealing hole 14 and the branch line air sealing hole can isolate the liquid flow channel from entering the atmosphere in the main line tin bath 2 and the branch line tin bath 2' / 2", thereby reducing the volatile condensation of the glass melt.

[0055] The present invention relates to a multi-line flow channel structure for a single kiln. The glass quality of a single kiln with two lines is the same as that of a single kiln with three lines. The molten glass of both the main line and the branch lines flows out of the cooling section 1, resulting in consistent glass quality. Furthermore, the cooling section 1 is smaller than the two cooling sections 1 used in the prior art for a single kiln with two lines, resulting in a smaller amount of molten glass being cooled and refluxed. The multi-line flow channel structure of the present invention is easy to retrofit and reconstruct, making full use of the existing glass melting furnace structure and plant. The tonnage of the main line and multiple branch lines can be flexibly adjusted, allowing the tonnage and product specifications of each line to be adjusted at any time according to actual production requirements.

[0056] Therefore, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0057] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
