AI Technical Summary
The stirring mechanism of traditional distillation equipment rotates around a fixed axis, which makes it difficult to cover all areas inside the distillation container, especially the edge, bottom and near the liquid surface of the container, which easily form dead corners, resulting in local temperature differences, inconsistent boiling points during the distillation process, and incomplete separation.
The mixing assembly is composed of a rotating rod and spiral blades. The rotating rod drives the spiral blades to form a negative pressure in the distillation container to suck in the liquid and spray it out at high speed, eliminating dead corners. Combined with the upper and lower mixing of the curved plate, the temperature uniformity and separation efficiency are improved.
It achieves all-round uniform heating of the liquid in the distillation container, eliminates dead corners, improves temperature uniformity and separation effect, and makes the distillation process more thorough.

TECHNICAL FIELD
[0001] The present application relates to the technical field of distillation equipment, and particularly relates to a distillation structure for a full-automatic analysis instrument. BACKGROUND
[0002] The distillation structure for the full-automatic analysis instrument is an integrated and intelligent liquid separation and purification module, which is designed for an analysis instrument and is used for efficiently completing sample distillation, concentration or purification tasks in an automatic process. The core feature is that through the fusion of mechanical, electronic and fluid control technologies, unattended, precise temperature control, efficient separation and real-time monitoring are realized, and the distillation structure is directly connected with a sample injection system or a detection module of the analysis instrument. Many samples contain a large amount of non-volatile impurities. Distillation can completely remove these interference substances by vaporizing the target volatile components through heating and then collecting the volatile components through condensation, thereby avoiding the clogging of the sample injection system of the analysis instrument or the pollution of the detector.
[0003] The stirring paddle in the stirring mechanism of the traditional distillation equipment is usually rotated around a fixed shaft, and the stirring range is limited by the size of the paddle and the rotating speed, so it is difficult to cover all areas in the distillation container, especially the dead angles formed near the edge, bottom and liquid surface of the container, which leads to local temperature difference: the liquid in the dead angle area is insufficiently in contact with the heating source, and the temperature is lower than that in the central area, causing incomplete separation of components with inconsistent boiling points in the distillation process. Therefore, the distillation structure for the full-automatic analysis instrument is proposed. SUMMARY
