Description

Rotary shaft device

The present invention relates to a sublimation purification apparatus, and more particularly to a rotary shaft apparatus for inserting an inner tube housing member for purifying a material into a sublimation purification apparatus.

Sublimation refers to the process in which a substance is directly converted from a solid to a gaseous state without passing through a liquid state. This change in state occurs when the temperature and pressure are lower than the triple point of the substance. Therefore, sublimation purification methods for separating different substances into a solid state or sublimating into a gaseous state by adjusting to a specific temperature and a specific pressure have been widely used.

In the prior art, the sublimation purification method is to heat the raw material into a sublimation purification device, and the target material in the raw material is sublimated into a gaseous state and output. Since the purity that can be obtained by a single purification treatment is limited, it is often necessary to perform the second and third purification treatments to achieve the purity requirement. For this reason, it is necessary to cool the material once sublimated once (about 3 hours) before it can be put into the sublimation purification equipment again for the next purification treatment. However, the process of this method is complicated, and the material needs to be moved repeatedly for cooling and sublimation, so that continuous operation is impossible, time-consuming and labor-intensive, thereby increasing the cost. Furthermore, venting is required in the process, which not only deteriorates the purification effect, but also has the possibility of contaminating the material.
