A rapid cooling device for tft substrate glass production channel

Abstract

The invention provides a fast cooling device for a TFT substrate glass production channel, which relates to the field of TFT substrate glass manufacturing. The TFT substrate glass production channel rapid cooling device includes a production channel and a cooling mechanism. The production channel includes a clarification section, a connection section and a cooling section. The clarification section is connected to the cooling section through the connection section. The cooling mechanism is arranged at the connection section between the clarification section and the cooling section, and is used to cool the glass clarified through the clarification section. The cooling mechanism includes a cooling pipeline and a valve, and the cooling pipeline runs through the connecting section. The valve is arranged on the cooling pipeline. The rapid cooling device of the TFT substrate glass production channel is provided with a cooling pipe running through the upper and lower parts of the connecting section and a valve is set on the cooling pipe. When the valve is opened during official production, the high-temperature gas is used to generate convection for cooling, which does not affect the heating of the kiln. It can achieve the purpose of rapid cooling and temperature control, and ensure the smooth progress of production and the stable improvement of product quality.

Description

technical field [0001] The invention relates to the field of TFT substrate glass manufacturing, in particular to a rapid cooling device for a TFT substrate glass production channel. Background technique [0002] In the melting production process of TFT substrate glass, the batch material needs to be cooled quickly after melting and clarification. The purpose is to improve production efficiency and shorten production time. Second, the product quality requires rapid cooling. Because the temperature required for glass clarification is high, and the temperature required for glass molding is low. At the same time, if the temperature cannot be cooled quickly after clarification, it is not conducive to the absorption of air bubbles. Therefore, in terms of product quality and production efficiency, it is necessary to quickly cool down. [0003] In order to quickly cool down, the current method is to remove the insulation structure of this section before production to achieve the pu...

Problems solved by technology

[0003] In order to quickly cool down, the current method is to remove the insulation structure of this section before production to achieve the purpose of rapid cooling. This method cannot accurately adjust to the required temperature at one time, and requires repeated operations. The operation cycle is long. It has a great impact on production; second, it is difficult to remove the insulation structure at high temperature, and the removal is uneven, forming local cold spots, prone to crystallization defects, and resulting in quality degradation
