Embodiment Construction

[0010] The object of the present invention is to design a glass pool furnace for melting high-boron, low-alkali or alkali-free glass. The structure includes a heating system matched with the glass pool furnace. The key is that the internal structure of the glass pool furnace includes a pre-melting pool 2 with a feed port 1, a cross-flame melting pool 3 connected to the pre-melting pool 2, and a lower channel 4-1 through the flow-limiting partition wall 4 for melting with the cross-flame The horizontal flame clarification pool 5 connected to the pool 3 communicates with the horizontal flame working pool 7 through the pipeline 6 and the horizontal flame clarification pool 5, and the forming channel 8 for conveying molten glass is arranged on the horizontal flame working pool 7.

[0011] In the above pool furnace heating system, one of natural gas, liquefied petroleum gas, or isobutane gas, or any two or three mixed combustion methods to provide heat is used.

[0012] In the glas...

Abstract

The invention relates to a glass tank for melting high-boron low-alkali or alkali-free glass and manufacturing a TFT-LED glass substrate. The glass tank comprises a heating system matched with the glass tank and is characterized in that: the internal structure of the glass tank comprises a pre-melting tank with a feed inlet, a cross flame melting tank connected with the pre-melting tank, a cross flame clarification tank communicated with the cross flame melting tank through a lower passage of a flow-limiting diaphragm wall, and a cross flame work pool communicated with the cross flame clarification tank through a pipeline; and a forming passage for delivering molten glass is formed on the cross flame work pool. The glass tank reasonably utilizes energy; and the generated molten glass has the advantages of quick temperature rise, uniformity and high defoaming efficiency.

Description

technical field [0001] The invention belongs to special equipment in the field of glass manufacturing, and in particular relates to the structural design of a glass pool furnace for melting high-boron, low-alkali or alkali-free glass. Background technique [0002] The current glass pool furnace has low efficiency, high heat consumption, and unsatisfactory clarification and homogenization effects when melting high-boron, low-alkali or alkali-free glass that is difficult to melt and homogenize. The obtained glass has a low pass rate and is not high in quality. To improve the melting and homogenization effect, the conventional improvement measure is to increase the temperature of the process index, which will inevitably accelerate the erosion of refractory materials and shorten the service life of the pool furnace. As a result, it will increase, resulting in more glass defects and reducing the high-quality rate of glass products. Contents of the invention [0003] The purpo...
