Description

Technical Field

[0001] This invention relates to the field of glass production and processing technology, specifically to a channel insulation structure for TFT-LCD substrate glass. Background Technology

[0002] In the production of TFT-LCD substrate glass, due to the extremely stringent quality requirements of liquid crystal displays (LCDs) for the glass substrate, an overflow-drawing method is typically used to produce the LCD substrate glass. The production process involves melting the batch material at high temperatures in a bath furnace to form a homogeneous glass molten liquid, which is then initially shaped through a bath furnace and a muffle furnace. During production, the bath furnace is used to feed the batch material and send the molten glass into a platinum channel for clarification and homogenization. The channel uses direct current heating, with current passing through a connecting flange to heat the platinum body (which has high resistance). To prevent localized overheating of the flange, cooling water is used inside the flange for cooling. Therefore, the flange area is heavier than the platinum body. Furthermore, to ensure the platinum body can expand and move during installation and heating, the flange area requires post-heating treatment (filling with powdered refractory material to allow free expansion of the body during heating). Therefore, the filling quality at this area is inferior to that at the body.

[0003] After long-term operation, the platinum body will become thinner due to platinum corrosion and volatilization, and there will be gaps between the refractory material and the body. The balance between the flange and the body will be broken, which may cause tearing between the flange and the body due to changes in weight balance. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned above in the background art, and to propose a channel insulation structure for TFT-LCD substrate glass.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A channel insulation structure for TFT-LCD substrate glass includes an insulation layer, a plurality of lower insulation bricks are laid on the top of the insulation layer, the plurality of lower insulation bricks are spliced ​​together to form an integral first insulation brick layer, a plurality of upper insulation bricks are also laid on the first insulation brick layer, the plurality of upper insulation bricks are spliced ​​together to form an integral second insulation brick layer, and the second insulation brick layer covers the first insulation brick layer.

[0007] A first groove is formed below the upper insulation brick, and a second protrusion corresponding to the first groove is formed on the top of the lower insulation brick. The lower insulation brick and the upper insulation brick are interlocked with each other.

[0008] The top of the insulation layer also has a first protrusion, and the bottom of the lower insulation brick has a second groove at the first protrusion. The first protrusion and the second groove are engaged, and the lower insulation brick is engaged with the top of the insulation layer by the first protrusion.

[0009] As a further aspect of the present invention: a heating channel is formed within the insulation layer, and a supporting brick is laid at the bottom of the insulation layer.

[0010] As a further aspect of the present invention: a flange is also provided on the heating channel, and a pipe body is connected to the flange.

[0011] The beneficial effects of this invention are: when installed in this part of the channel during channel installation, the expansion of this part during the heating process will not create gaps between it and the channel body and flange, thereby improving the condition of the channel body and increasing the service life of the channel.
