Description

Technical Field

[0001] The 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] At present, most of the flat glass float production lines at home and abroad are "one kiln and one line", that is, one kiln is connected to a float tin bath through a flow channel. Its daily output ranges from 150 tons / day to 1,200 tons / day. The thickness of the produced glass covers a variety of specifications such as 1.1 to 22 mm. As the daily melting tonnage increases in glass production, the energy consumption per unit product of flat glass decreases. In order to reduce the energy consumption of glass production, many domestic glass manufacturers tend to build large-tonnage float glass production lines. However, in the "one kiln and one line" production model, as the daily output increases, thin glass with specifications of 1.1 to 3 mm is difficult to produce.

[0003] In order to solve this problem, the "one kiln, two lines" large-tonnage float production line was born. At present, the solution of the "one kiln, two lines" float glass production line is to add a bypass branch from the cooling part of the kiln on the basis of the "one kiln, one line", and extend another parallel cooling part through the bypass branch. The two cooling parts are connected to their respective flow channels, and a production line is formed with the corresponding float tin bath. Usually, the production line facing the center of the kiln is called the "main line", and the one parallel to the center line of the kiln is called the "branch line". During the operation of the "one kiln, two lines" float production line, the main line tonnage is small and produces thin glass. The branch line tonnage is often large and produces thick plate glass.

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

[0005] 1. Difference in glass quality. Limited by the kiln structure, the glass quality of the main line and branch line is quite different. Usually, the glass quality of the main line is better than that of the branch line.

[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 and one line" of the same tonnage, the kiln of "one kiln and two lines" has two cooling sections, and the investment is about 1.5 times that of the "one kiln and one line" of the same tonnage.

[0008] 4. Cold modification and reconstruction is difficult. When the "one kiln and one line" is transformed into "one kiln and two lines", the original kiln structure cannot be reused, and additional cross passages and cooling parts are newly added. The original plant structure is difficult to reuse, and the plant layout needs to be expanded.

[0009] 5. There must be a certain difference in tonnage between the main line and the branch line. Generally, the tonnage of the main line is much lower than that of the branch line, and the tonnage of the branch line is 1.5 to 2 times that of the main line. The tonnage cannot be flexibly adjusted between the two lines. The specifications of the produced glass are also incompatible. Summary of the invention
