Description

This invention belongs to the field of substrate glass manufacturing technology, and more specifically, relates to a highly efficient supply device and method for supplying material to the flange base in the clarifying section of a platinum channel under specific thermal conditions. Platinum channels are core components in the substrate glass manufacturing process, requiring phased support operations based on various operational scenarios and final equipment operational requirements, including design, manufacturing, stone installation, and temperature expansion piping. The clarification section has the highest operating temperature within the platinum channel structure and is a highly fragile component. While platinum channels are primarily made of platinum-rhodium alloy, offering excellent high-temperature and corrosion resistance, prolonged operation exceeding 1400°C and continuous erosion by the internal glass liquid remain extremely challenging for the platinum matrix itself. In the initial installation process of the platinum channel, most of the clarified area can be sealed under room temperature conditions. This sealing method primarily involves using high-temperature resistant zirconium powder to seal the space between the platinum exterior and the refractory bricks. However, for the flange region of the platinum channel, relative expansion occurs between the platinum and the refractory material during the actual heating process, and because the flange itself is larger than the refractory bricks, it is necessary to pre-secure space in the flange region of the clarified area. After thermal expansion is complete, rapid supply is performed at high temperatures to ensure the final sealing effect at the flange base. Based on years of line body analysis, the primary issue limiting the lifespan of platinum channels is the flange base region of the clearing section. While this region is eventually supplied under thermal conditions, the harsh operating environment, confined space, and demanding technical requirements for operators at high temperatures still result in a disparity compared to the room-temperature supply in the clearing main section. Comprehensive analysis reveals that the density of thermal supply at the flange base only reaches approximately 70% of the platinum supply in the main section. Therefore, in actual production, partial cracking first occurs in the flange base region after two years of channel operation. This is due to oxidation at high temperatures, which leads to excessive volatilization of the matrix material, ultimately significantly thinning the tube wall thickness. Further deterioration leads to eventual rupture of the platinum tube body in that region. This rupture depends not only on the reduction in wall thickness but is also accelerated by localized Joule heating caused by the operating current. This demonstrates the intended structure of the flange region in the channel clarification area of current technology.This invention demonstrates the overall intent of the refractory brickwork in the flange region of the channel clearing section.This is a layout diagram of the supply structure in the flange region of the channel clearing section of the present invention.This is the intended design of the side-addition supply trough structure of the present invention.This is the intended design of the top-surface additive supply trough structure of the present invention.
