Embodiment
[0044] A welded sealing structure for platinum channels in the substrate glass manufacturing process according to an embodiment of the present invention includes a solid refractory component, which has at least one curved surface that fits the outer contour of the molten glass channel, and the solid component has a hole inside The structure is used for two even wires 2 to pass through it respectively.
[0045] The sealing structure includes a porcelain block 4, and separate special-shaped through-holes are arranged inside the porcelain block 4, through which two even wires 2 pass through respectively. The curved surface 6 structure on the inner surface of the porcelain block 4 can be closely attached to the body of the platinum channel 5 to achieve a sealing and fixing effect.
[0046] The separated bare wires 2 drawn from the outside of the porcelain block 4 are respectively packaged with protective porcelain beads. The protective magnetic bead adopts a ball head to protect ...

The invention discloses a welding sealing structure for a platinum channel in the substrate glass manufacturing process and a using method of the welding sealing structure. The welding sealing structure comprises a porcelain block and a plurality of ball head porcelain beads. The porcelain block is provided with a first through hole and a second through hole for a thermocouple wire to penetrate. The bulb porcelain beads sleeve the exposed thermocouple wire and are used for protecting the exposed thermocouple wire; the porcelain block is provided with a cambered surface, and outlets of the first through hole and the second through hole are located in the cambered surface and used for achieving butt welding of thermocouple wires; the cambered surface is used for being attached to the outlineof the outer wall of the platinum channel. According to the welding sealing structure, the sealing performance of the root of the thermocouple wire can be effectively enhanced, and the stability andreliability of the thermocouple can be improved.
Description
technical field [0001] The invention belongs to the technical field of substrate glass manufacturing, and in particular relates to a welding and sealing structure for platinum passages in the substrate glass manufacturing process and its application method. Background technique [0002] In the manufacturing process of TFT-LCD substrate glass, the process temperature is an important parameter index; in addition to installing ordinary plug-in thermocouples on the equipment, a large number of welded thermocouples are also used in the platinum channel area. When the high-temperature glass melt flows through the platinum channel, precise clarification, homogenization and cooling processes are required to make the glass melt meet the high-quality requirements of temperature and viscosity required for forming. see figure 1 , at present, because the melting and shrinking bead of the welded thermocouple wire end is directly or indirectly welded to the platinum channel body, there is...
