Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a rapid cooling device for glass plates. Background Art

[0002] The overflow down-draw method is one of the primary methods for producing flat glass. Molten glass overflows from both sides of a refractory chute and converges at the lower tip of the chute, forming a glass sheet. This sheet is then drawn through a traction mechanism. Because the glass surface never comes into contact with any other material, this method produces thin glass sheets with a smooth, flat surface and uniform thickness.

[0003] During normal production on the current production line, the temperature of the glass plates at the BOD packaging station is 50-55°C. During centralized packaging, the temperature of the glass plates at the previous packaging and sorting stations is around 55°C. Due to the high temperature of the glass plates during packaging, combined with the influence of factors such as the tension of the glass plates themselves and the packaging process, the glass plates are prone to bulging up and down after being packaged onto the A-frame. As the number of packages increases, the uneven packaged glass after bulging can easily cause the glass plates inside to be squeezed and broken. At the same time, the packaging team also faces the risk of squeezing and breaking plates due to packaging operations when packaging and putting them into storage.

The air outlet component 1 can be set on an adjustment seat, and the air outlet angle and blowing position of the air outlet component 1 can be adjusted by the adjustment seat.

[0036] The working principle of this utility model is as follows: During the packaging process of a glass plate production line, the glass plates are prone to crushing due to the high temperature of the glass plates from the previous process, coupled with the tension of the glass plates themselves and the packaging process. Therefore, the glass plates need to be cooled in the production line. The existing cooling method is electrostatic blowing, which cannot meet the requirements to reduce the temperature of the glass plates, and solve the problems of excessively high plate temperatures causing bulging during packaging and plate breakage during packaging. This application is applied to the packaging area of ​​the semi-finished product process and is equipped with an air intake device and a heat exchange structure 2 for cooling. After the air from the air intake device is cooled by the heat exchange structure 2, the cooled airflow is blown toward the glass plates through the air outlet assembly 1 to cool the glass plates, effectively solving the existing problems of excessively high plate temperatures causing bulging during packaging and plate breakage during packaging. It also improves the quality of semi-finished product packaging. The air output of this device can be adjusted according to the usage situation, and the heat exchange structure 2 cools the airflow while slowly releasing and homogenizing it, reducing the direct impact of the airflow. Improves the stability of the glass sheet during operation, effectively lowering the sheet temperature while reducing the risk of shaking and breakage. The cooling air volume can be adjusted manually or automatically online, improving the stability of the glass sheet during operation and reducing damage caused by collisions.
