Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of glass kiln relates to a TFT glass pool furnace flue mouth automatic opening and closing gate. BACKGROUND

[0002] During the production process of substrate glass, a large amount of waste gas is generated, which must be effectively discharged through a carefully designed flue system to ensure the cleanliness of the production environment and the continuity of production. As the key part connecting the glass kiln and the external environment, the performance of the flue system is directly related to the efficiency of waste gas emission and the stability of glass production. However, in the actual production process, due to the small particulate matter carried in the waste gas and the deposits generated by chemical reactions, the inner wall of the glass kiln flue often accumulates a large amount of dust and dirt. Over time, these dust and dirt not only gradually reduce the flue's smoke emission efficiency, but also can form a thick deposition layer, which can even cause partial or complete obstruction of the flue. This obstruction not only affects the smooth emission of waste gas, but also damages the pressure balance inside the kiln, thereby adversely affecting the pool furnace process, such as uneven temperature distribution and decreased melting efficiency. Therefore, regular flue cleaning operations to remove dust and dirt from the inner wall are necessary measures to maintain the stability and efficiency of glass production. During the flue cleaning process, opening the flue gate is a crucial step. However, this step is often accompanied by a dramatic fluctuation in kiln pressure. When the flue gate is opened, the gas inside the kiln rapidly escapes, causing the furnace pressure to drop sharply; when the gate is closed, gas backflow may occur, causing the furnace pressure to rise. This pressure fluctuation is very detrimental to glass production, as it can interfere with the chemical reactions and temperature distribution inside the pool furnace, resulting in defects such as nodules, bubbles, and other defects in the glass product, severely affecting the quality and yield of the glass. To address this issue, the flue gate opening device of the glass kiln needs to be precisely adjusted.

[0003] However, the existing flue gate position adjustment method mostly relies on manual operation, which not only has low efficiency, but also makes it difficult to ensure timely response to the stabilization of the pool furnace process during the opening process. Due to the limitations and uncertainties of manual operation, the pressure fluctuation inside the kiln often cannot be effectively controlled in a timely manner, making the pressure environment inside the kiln increasingly unstable, further exacerbating the quality problems in the glass production process.
