Temperature control device of cooling area of platinum channel

Abstract

The invention discloses a temperature control device of a cooling area of a platinum channel, and belongs to the technical field of substrate glass manufacturing. According to the invention, the top of the cooling pipe is designed to be of an upward-arched special-shaped structure, so that the stability of the top structure can be improved, and meanwhile, the special-shaped cooling pipe structure can realize uniform and efficient heat dissipation of internal glass liquid; the heating bricks matched with the outer contour design of the cooling pipe provide supporting force, and the heating bricks and the cooling pipe jointly form the temperature control device. According to the special-shaped platinum cooling pipe, inward arc chamfer design is carried out on the two sides based on the reference contour of a circular pipe, so that the center area is closer to the outer contour, and the overall uniform heat dissipation capacity of glass in the pipe is improved; the upper and lower surfaces of the special-shaped platinum cooling pipe are designed into arc structures based on the reference contour of a circular pipe, the stability problem of the upper and lower plane structures is solved, and top collapse deformation can be prevented.

Description

technical field [0001] The invention belongs to the technical field of substrate glass manufacturing, in particular to a temperature control device for a cooling zone of a platinum channel. Background technique [0002] The platinum channel is one of the key equipment in the substrate glass manufacturing process. It is made of precious metal materials such as platinum and rhodium, which is expensive and has a high loss rate. Therefore, it is of great significance to improve the life strength of the equipment itself. The platinum channel mainly includes the heating and clarifying zone, the stirring zone, the cooling and cooling zone and the feeding zone. The cooling and cooling zone is based on the fact that the glass liquid has high-quality uniformity after the completion of the first two processes. To effectively cool down, it is also necessary to ensure the controllability of the cooling process. Therefore, the platinum cooling pipe generally adopts a wide cross-section an...

Problems solved by technology

[0003] For the current platinum cooling pipe, it mainly adopts a large cross-section flat pipe structure, such as Figure 5 As shown, the upper and lower sides of the flat tube platinum cooling tube 8 adopt a wide planar structure, and both sides adopt a semicircular structure. Gap 9; the upper and lower sides of the flat tube platinum cooling tube 8 mainly play the role of rapid heat dissipation, but due to the large plane structure on the upper and lower sides, the wall thickness of the platinum tube is generally designed between 0.8 and 1.5mm, and the properties of the large plane and thin-walled structure , which determines whether it is in the process of processing or in the process of high temperature operation, it is very prone to shaking and collapse problems. From the actual use point of view, in the operation of the line body, the high temperature state of about 1300 ℃, the platinum rhodium alloy material The top of the cooling flat tube frequently has the problem of collapse and deformation. When the temperature reaches above 1200°C during the heating stage, the welded couple installed on the top of the cooling tube is damaged at multiple points, and the corresponding side couple is not damaged. It fully shows that the top of the cooling pipe collapses at high temperature. This collapse not only affects the normal process temperature monitoring, but also affects the stability of the flow of molten glass, and even the life reliability of the equipment.
