Blast cooling equipment for platinum channel

Abstract

The invention discloses blast cooling equipment for a platinum channel. The blast cooling equipment is divided into two space areas including a cooling chamber and a blast chamber by semi-circular-annular air leakage bricks, ventilation holes are uniformly distributed in each semi-circular-annular air leakage brick, and a set of supporting bricks and a structure of air inlets and air outlets are installed at two modified ends. According to the equipment disclosed in the invention, after cooling air enters the blast chamber from an air supply opening, the air is uniformly dispersed after passing through ventilation openings, the dispersed air enters the cooling chamber, the cooling air cools the outer wall of the platinum channel while moving quickly towards inner air outlets and outer airoutlets located at two sides, thereby indirectly cooling molten glass in the platinum channel, and the purpose of cooling is achieved by the repeated cycle cooling; and at the same time, the cooling equipment can be installed in any place that needs to be cooled, of the platinum channel, the air supply volume and speed of the cooling air are adjusted according to cooling range of the molten glassin the platinum channel, and the equipment has high flexibility, and realizes precise cooling of the molten glass.

Description

【Technical field】 [0001] The invention belongs to the technical field of substrate glass manufacturing, and in particular relates to a blast cooling device for a platinum channel. 【Background technique】 [0002] The platinum channel is one of the very important equipments in the manufacturing process of the substrate glass. After the initial melting of the batch materials in the pool furnace, the glass liquid with relatively uneven composition and a large number of bubbles needs to flow through the platinum channel for multiple channels. The processing of the process can meet the quality requirements of overflow molding. The clarification section of the platinum channel raises the temperature again at the front end to make the molten glass achieve the temperature and viscosity conditions required for the clarification process. The whole process requires continuous and stable high temperature to perform clarification and foam removal process on the molten glass. The clarifie...

Problems solved by technology

The current heating method in the cooling section adopts direct heating with electrodes, which meets the requirements in the regulation of heating and heat preservation, but the regulation of cooling is only realized by the design of the length of the cooling pipe body, which is not very flexible, and the change in the length and size of the cooling section has great impact on the factory building. Therefore, the present invention aims to design an auxiliary blowing device around the cooling tube to achieve uniform and stable air cooling adjustment, so that the temperature of the entire glass liquid can be satisfied by two-way precise adjustment.
