Description

Technical Field

[0001] The utility model belongs to the technical field of high-temperature drying ovens, in particular to a high-temperature drying oven. Background Art

[0002] In crystal preparation, some solvents are usually used, such as hydroiodic acid, hydrobromic acid, hydrochloric acid, etc. These solvents will remain in the crystals during the crystallization process and become impurities of the crystals. The high-temperature drying oven can provide a high-temperature environment to remove residual solvents in the crystals and improve the purity of the crystals.

[0003] At present, high-temperature drying ovens generally have exhaust holes to directly evaporate the solvent into steam at high temperature and discharge it. If the ventilation is insufficient, it is easy to pollute the environment. In addition, such exhaust holes will allow oxygen to enter, causing oxidation of the crystal surface, resulting in poor purity and quality of the crystal. For this reason, we propose a high-temperature drying oven. Utility Model Content

At the same time, the vacuum machine extracts the air in the operating room to create a vacuum oxygen-free environment to avoid oxidation of the crystal surface. At the same time, the solute vapor is extracted from the operating room by the vacuum machine and condensed into liquid when passing through the condenser, and then flows into the collection bin through the conduit. After receiving, the conduit is removed from the feed pipe, and the collection bin is removed from the box for cleaning, thereby achieving the effect of improving the purity and quality of the crystal and avoiding environmental pollution.
