Description

Technical Field

[0001] This utility model belongs to the technical field of glass production equipment, specifically relating to a rapid cooling device for tempered glass production. Background Technology

[0002] The production process of physically tempered glass mainly includes two key steps: heating and quenching. After the glass is heated to above its softening point in a furnace, it is rapidly transferred to a cooling device and cooled quickly and uniformly by high-pressure gas (usually air). The surface cools and solidifies rapidly, while the interior cools slowly, thus creating compressive stress on the glass surface and tensile stress inside, which greatly improves the glass's mechanical strength and thermal shock resistance.

[0003] Existing cooling devices (wind tunnels) typically suffer from the following technical defects: 1. Low cooling efficiency: In order to improve cooling efficiency, the cooling speed is accelerated by increasing the air pressure and air volume. However, excessive cooling air can easily cause the glass surface to shrink excessively, creating a huge stress difference with the interior and causing it to crack directly. Conversely, insufficient cooling will result in insufficient tempering (low stress value).

[0004] Second, high energy consumption: The use of multiple high-power fans running at full power continuously results in huge energy waste during cooling, and at the same time, heat may not be able to be dissipated during cooling.

[0005] 3. Poor adaptability: A fixed nozzle layout and fan system is difficult to simultaneously optimize and adapt to the cooling process requirements of glass with different thicknesses (such as 3mm ultra-thin glass and 19mm thick glass) and different sizes. Summary of the Invention

The roller body 2-1 is made of high-temperature resistant ceramic roller body.

[0029] Specific implementation method three: Combining Figures 1 to 4The illustration shows this specific embodiment, which is a further limitation of embodiment one or two. In this specific embodiment, the initial cooling of the glass is achieved by suction and blowing in the primary cooling zone 3-1.
