Platinum channel mixing barrel and platinum channel mixing barrel device

Abstract

The invention relates to a platinum channel mixing barrel and a platinum channel mixing barrel device. The platinum channel mixing barrel comprises a stirring barrel body with a barrel opening, a molten glass inlet and a molten glass outlet, wherein the mixing barrel body is also communicated with a hot-gas supply device for blowing an inert hot gas into a space above a free water surface in the mixing barrel body, so that the inert hot gas blown by the hot-gas supply device flows into the space above the free water surface and then is sent out from the barrel opening. Oxygen in the space is diluted and discharged by blowing the inert hot gas into the space above the free water surface in the mixing barrel body, so that volatilization of a precious metal component exposed in the space is inhibited and a precious metal volatile matter of generating precious metal defects is reduced from the source. The generated precious metal volatile matter can be taken out of the space along with continuous injection of the inert hot gas into the space above the free water surface, and the condensation of the precious metal volatile matter can be reduced, so that the probability of generating the precious metal defects in a glass substrate is reduced and the yield and the quality of a product are improved.

Description

Technical field [0001] The present disclosure relates to the field of glass substrate production equipment, and in particular to a platinum channel stirring barrel and a platinum channel stirring barrel device. Background technique [0002] In the glass substrate manufacturing process, the furnace process melts the batch materials into molten glass and then reaches the platinum channel process for clarification and homogenization. The molten glass passes through the platinum channel process and then is sent to the forming process to be made into a glass substrate semi-finished product. After the semi-finished product is processed The finished product is then packaged and transported to the panel manufacturer for use. [0003] Due to the development of demand in the consumer market, panel manufacturers have followed closely the display accuracy of panels and the market’s pursuit of ultra-thin products. In turn, the requirements for glass substrates have become higher and higher. As ...

AI Technical Summary

Problems solved by technology

However, the temperature in the mixing tank area will be greatly affected during the cleaning or replacement process, and a large amount of volatiles will fall into the glass liquid in the mixing tank during the cleaning or replacement process, which will cause a large number of defects. Among them, the precious metal defects will sink to the bottom of the mixing tank due to the specific gravity, and it will take several days or even weeks to be taken away by the molten glass, which seriously affects the normal operation of the production line and restricts the quality of the production line substrate glass. rate increase and increased equipment replacement costs
