Multi-pair electrode structure for TFT substrate glass tank furnace electric melting system

Abstract

The invention discloses a multi-pair electrode structure for a TFT substrate glass tank furnace electric melting system. The structure comprises a kiln, wherein a plurality of feeders are arranged ona front tank wall at the front end of the kiln in a communicating manner, a channel is arranged on a rear tank wall at the rear end of the kiln in a communicating manner, a plurality of groups of electrode mounting cylinder components are fixedly arranged on the side tank walls located at two sides of the kiln, and an electrode assembly is inserted into each electrode mounting cylinder assembly. According to the invention, when the electrode assemblies are inserted into the side pool wall of the kiln through the electrode mounting cylinder assemblies, electrode stems are inserted into electrode mounting outer cylinders through mounting slots and extend into the kiln, positioning corrugated elastic pieces on the inner side face of a mounting supporting arm plate abuts against and slides inU-shaped mounting plates in a guiding mode, and sheet bodies at the two ends of the positioning corrugated elastic sheets abut against and are positioned and clamped between multiple positioning protruding heads through positioning gaps; and electrodes are inserted into the tank walls on the two sides of a tank furnace in a horizontal lateral inserting mode, and each pair of electrodes form a loopthrough glass to be heated, so temperature difference in molten glass is small, and melting quality is guaranteed.

[0003] The existing technology has the following problems: the function of the substrate furnace is to form molten glass through physical and chemical reactions at high temperatures to achieve the quality of molten glass required for production. With the maturity of glass melting technology and the update of melting process, substrate glass The larger the area of ​​the furnace, the greater its production capacity, so if you want to increase the production capacity (the melting rate remains the same), you must increase the melting area, but the width of the furnace and the length of the flame, the width of the large wall, the electrode (glass conductivity) feeding size, etc. Therefore, when the width of the pool furnace is constant, the design length of the pool furnace is getting longer and longer, because the heat absorbed by the batch material is proportional to its coverage area. The longer the pool furnace, the more conducive to improving melting capacity, thermal efficiency and energy saving. , in order to better improve the melting efficiency of the glass in the pool furnace, when the width of the pool furnace remains unchanged, the logarithm of the electrodes used in the pool furnace is changed. The number of electrode pairs in the pool furnace depends on the length of the pool furnace. There is a lack of a The multi-pair electrode structure of the TFT substrate glass pool furnace electrofusion system is convenient for disassembly and adjustment of the electrode distance, which is not conducive to the electrofusion operation of the TFT substrate glass pool furnace
