技术领域
本发明涉及电子玻璃制造设备技术领域，特别是涉及一种主要用于8.5代及以上高世代TFT玻璃基板生产过程中的大流量贵金属通道。
背景技术
利用贵金属通道处理玻璃液的技术是目前生产TFT玻璃最常用的方法。这种方法利用了贵金属的耐温性好、可直接通电加热及延展性好等优点，可通电直接加热至1650℃，可实现TFT基板玻璃液高温下有效排泡，达到高质量澄清均化的作用，是生产TFT玻璃的关键技术装备，易于实现大批量生产，国内外很多专利和文献涉及了这方面的工艺。如中国发明专利CN101935146B阐述了一种铂金通道中玻璃液的处理方法，通过一个澄清仓、一个冷却仓、一个搅拌仓、一个均质仓和一个供料仓的五段处理步骤实现5～20吨/天的玻璃液流量的澄清均化，但该方法的处理能力还很有限，高于20吨/天的大流量玻璃液会由于需要的铂金管太大无法保证高温机械强度，无法实现高质量稳定澄清；中国发明专利CN105948462A涉及一种铂金通道加热装置、方法及铂金通道和玻璃生产系统，利用该装置产生交变磁场，在铂金通道上形成感生电涡流，电涡流流经铂金通道产生热量，实现对铂金通道的均匀加热，但该发明没有涉及大流量玻璃液的具体处理方法。

在本发明的一些实施方式中，在汇流通道另一端依次连通有至少一个玻璃液搅拌槽，且相邻的两个玻璃液搅拌槽的搅拌方向不同。
在本发明的一些实施方式中，所述加热通道的直径为150mm-300mm长度为500mm-1500mm；所述澄清槽的直径为250mm-400mm长度为3000mm-8000mm；所述冷却通道的直径为220mm-360mm长度为2000mm-6000mm；所述汇流通道的直径为300mm-500mm长度为2000mm-5000mm；所述玻璃液搅拌槽的直径为350mm-550mm，搅拌转速为2圈-20圈每分钟；所述供液槽的直径为300mm-500mm长度为1000mm-2000mm。
在本发明的一些实施方式中，所述加热通道工作时的最高温度为1650℃，所述澄清槽工作时的最高温度为1670℃，所述冷却通道的工作时的温度为1500℃～1550℃，所述供液槽工作时的温度为1200℃～1400℃。

本发明实施例有益效果：
本发明实施例提供的大流量贵金属通道，技术装备简单、可操作性强、澄清均化效果优、通过设置至少两条并行的玻璃液加热澄清冷却段，可实现大流量玻璃液高温加热澄清的同时，也可充分保证高温段铂金的使用寿命和高温机械强度，在确保高产量的前提下，避免了制造单根大直径玻璃液通道在高温段因大流量高液位玻璃液的压力作用而发生坍塌的风险的问题。
