Neck liquid flow inner-cooling type combined adjusting flashboard of glass melting furnace

The utility model discloses a neck liquid flow inner-cooling type combined adjusting flashboard of a glass melting furnace. The flashboard comprises a water pipe, a fused quartz brick and an anti-erosion coating. The water pipe is a thin-walled pipe, a water-stop sheet is adopted in the water pipe to achieve a separated and sleeve type structure, the fused quartz brick is fixed to the water pipe through a positioning pin, and the contact face of the quartz brick and glass liquid flow is coated with an anti-erosion coating. According to the utility model, the heat exchange efficiency is improved, the energy is saved, the consumption is reduced, the molten glass corrosion resistance of the flashboard is enhanced, the crystallization phenomenon is effectively avoided, and condensation fallingobjects are reduced. 本实用新型公开了一种玻璃熔窑卡脖液流内冷式组合调节闸板，所述闸板包括水管、熔融石英砖、抗侵蚀涂层。水管为薄壁管，内部采用隔水板实现分隔式、套管式结构，熔融石英砖采用定位销固定在水管上，在石英砖与玻璃液流接触面涂覆抗侵蚀涂层。本实用新型增加了换热效率，节能降耗，增强了闸板抗玻璃液侵蚀性能有效地避免析晶现象，减少冷凝掉落物。
