Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of reduced pressure distillation, in particular to a reduced pressure distillation device. BACKGROUND

[0002] Distillation is a thermodynamic separation process, which uses the different boiling points of components in mixed liquids or liquid-solid systems to evaporate low-boiling components and condense them to separate the entire component unit operation process, which is a combination of evaporation and condensation. Reduced pressure distillation belongs to distillation, which is suitable for the separation and purification of high-boiling substances and compounds that are decomposed, oxidized or polymerized when heated at normal pressure.

[0003] Publication No. (CN221451736U) discloses a traditional Chinese medicine reduced pressure distillation device, which adds traditional Chinese medicine into the distillation tank through the feeding assembly. When the liquid medicine is distilled, the heating plate on the inner wall of the distillation tank and the heating pipe on the stirring rod are used to heat the liquid medicine at the same time. This not only heats the periphery of the liquid medicine, but also heats the inside of the liquid medicine. During the distillation process, the stirring rod is driven by the first motor to rotate, which can not only realize the stirring and heating of the liquid medicine, but also accelerate the mixing of the liquid medicine and improve the uniformity of heating. With the continuous rotation of the heating pipe, the heating pipe can heat the liquid medicine at different positions, further improving the uniformity of heating and the distillation efficiency. During the distillation process, the internal pressure of the distillation tank will gradually increase, which may cause the risk of bursting of the distillation tank, and needs to be improved.
