One kiln multi-line molten glass shunt melting furnace

Abstract

The invention discloses a one-kiln multi-line molten glass shunting melting furnace, which comprises a melting part, a neck, a working part and branch paths, wherein the melting part is communicated with the working part through the neck, the melting part is used for heating, melting and clarifying molten glass, the front portion of the working part is wide, the rear portion of the working part isnarrow, and a plurality of the branch paths are arranged on two sides of the working part. According to the invention, the novel one-kiln multi-line molten glass shunting melting furnace can meet thelow-energy-consumption plate glass production of a 800-1250 ton large-tonnage melting furnace, can improve the uniformity of molten glass in each branch path and the glass quality, and can effectively solve the quality problems of large temperature difference of molten glass in each branch path, poor uniformity and the like in the molten glass shunting process of a one-kiln multi-line melting furnace, particularly a one-kiln melting furnace with more than four lines.

Description

technical field [0001] The invention relates to the technical field of flat glass melting furnaces, in particular to a multi-line glass liquid splitting melting furnace with one furnace. Background technique [0002] For the production of flat glass such as architectural glass, automotive glass, photovoltaic glass and ultra-thin electronic glass, the melting furnace is the key equipment for melting glass liquid. Its structural form and characteristics directly affect the energy consumption and quality of glass. [0003] Large-tonnage melting furnaces with a daily melting capacity of more than 800-1250 tons have become a development trend due to their obvious energy-saving advantages. However, subject to different specifications (thickness / plate width), different glass forming process principles (rolling / float) and the matching ability of forming and annealing equipment, the single-line production capacity of 1mm and below ultra-thin float forming process is 30-120 tons / day...

AI Technical Summary

Problems solved by technology

[0007] When the molten glass enters the horizontal passage through the neck, the molten glass dissipates heat quickly due to the relatively narrow and long horizontal passage, which not only causes a large lateral temperature difference in the flow direction of the molten glass, but also causes the flow to be diverted between the far and near branch passages. There are large differences in the temperature and uniformity of the molten glass, and the quality of the molten glass in each channel varies greatly

When the molten glass passes through the neck, the horizontal passage, and the branch passage, it needs to turn multiple times at large angles. The flow rate and temperature difference of the molten glass on both sides of the corner are relatively large, and it is easy to form a "dead angle" where the molten glass is almost static. Cause glass crystallization and accumulation of impurities to cause glass defects, especially when more than 5 branch channels need to be set up, the horizontal channels are longer and have more corners, and the quality of glass liquid between each branch channel and between them is more difficult to guarantee
