Description

Technical Field

[0001] The utility model relates to the field of substrate glass production, in particular to a tool for replacing channel cover bricks. Background Art

[0002] In the glass manufacturing industry, the overflow down-draw process is widely adopted due to its unique advantages, particularly for the production of high-precision, demanding TFT substrate glass and high-aluminum cover glass. By precisely controlling the flow and shaping of molten glass, this process produces glass products with excellent optical properties, high uniformity, and low defect rates. As a key piece of equipment, the channel stirring tank plays a crucial role in this process.

[0003] The core of the overflow down-draw process lies in ensuring a high degree of uniformity and stability in the molten glass before forming. The stirring tank, a key device for homogenizing the molten glass, continuously mixes and stirs the molten glass through its internal stirring mechanism, effectively eliminating glass defects caused by factors such as temperature gradients and uneven composition. This homogenization not only improves the purity and consistency of the molten glass, but also significantly enhances the optical properties and mechanical strength of the final product, meeting the stringent quality and stability requirements of TFT substrate glass and high-aluminum cover glass.

[0004] However, in high-temperature, high-humidity production environments, the cover tiles at the top of the mixing tank face significant challenges. Prolonged high-temperature baking and humidity erosion can easily cause physical and chemical changes in the cover tile material, leading to surface cracking and flaking. Especially when operators directly touch the underside of the cover tile to replace it, the increased brittleness of the material at high temperatures and changes in surface roughness can easily cause further damage and debris to the cover tile. Once this debris enters the melt or contaminates the channel, it can severely affect the purity and fluidity of the molten glass, further introducing more glass defects such as bubbles, streaks, and inclusions during the forming process, severely reducing product quality and yield.

[0005] To address this issue, the current, tool-free method of replacing cover bricks exacerbates the difficulty and risk of replacement. While cover bricks typically feature a curved surface to better accommodate the structural and functional requirements of the mixing tank, this design, while aesthetically pleasing and practical, also introduces significant inconvenience during replacement. Operators often struggle to maintain a steady grip on the cover bricks during replacement, and are prone to touching the underside due to obstructed vision or trembling hands, further increasing the risk of damage and contamination.

[0006] Therefore, how to safely and efficiently replace the cover bricks on the top of the mixing tank in a high temperature and high humidity environment has become one of the technical bottlenecks restricting the further development of the overflow down-draw process. Utility Model Content
