[0002] High-purity metals refer to metals with very high purity, usually at a purity level of more than 99.999% (5N). This purity usually requires that there are almost no impurities in the metal, especially extremely low content of other metals, non-metallic elements and oxygen. High-purity metals are usually obtained through refining, smelting and purification processes to meet specific industrial needs and scientific research requirements. High-purity metals are widely used in many fields. High-purity metals with a purity level of 99.9999% (6N) are used in optics, photovoltaic energy, etc., and high-purity metals with a purity level of 99.99999% (7N) are used in semiconductors, etc. Their high purity makes their physical and chemical properties more predictable and stable, suitable for applications that require precise control and high performance.

[0031] In this embodiment, cold air is delivered by the refrigeration fan 43, and the cooling effect is further enhanced by the four cooling fans 42, so as to realize rapid cooling and cooling of the quartz tube 21. By the mutual cooperation between the components in the two sets of transmission assemblies 3, the two driving motors 31 can be controlled to drive the slider 34 to move within the travel range of the limit rod 36, and drive the installation bucket 4 connected by the connecting plate 35 to move, and finally drive the four cooling fans 42 and the two installation buckets 4 to move, and evenly cool the nine quartz tubes 21.
