Description

TECHNICAL FIELD

[0002] Distillation is a thermodynamic separation process that uses the different boiling points of components in a mixture of liquids or liquid-solid systems to evaporate low-boiling components and condense them to separate the entire component unit operation process. The advantage is that it does not need to use other solvents other than the system components, so as to ensure that no new impurities are introduced. Distillation is one of the commonly used methods for drug detection. In the process of drug detection, the method of distillation is usually used to separate the components in the drug.

[0003] In the literature CN216222996U, an efficient distillation device for drug detection is disclosed. To solve the problems in the background art, the following scheme is proposed, which includes a cylinder, a feed cylinder is arranged on one side of the cylinder, and a feed pipe is connected at the bottom of the feed cylinder, a condensing hopper is arranged at the top of the cylinder, and a connecting pipe is connected through the outer wall on one side of the condensing hopper, an outlet pipe is connected through the bottom of the condensing hopper, and a distillation tank is connected through the bottom end of the connecting pipe. The utility model discloses a hollow condensing hopper. When the steam in the distillation tank enters the cavity through the connecting pipe, the steam and the cold water in the condensing hopper can be fully contacted due to the small space in the cavity, so that the steam can be liquefied more quickly, and the liquefied liquid flows into the outlet pipe and is discharged. There is no need to worry about the liquid dripping into the cylinder, which can ensure the dryness of the cylinder.

[0004] The above-mentioned prior art discloses a distillation equipment for drug detection, which usually uses liquid drug in the tank body, controls the heating temperature to realize the evaporation of different components in the drug, and then realizes the condensation effect through the condensing hopper and the cold water in the condensing hopper. However, when condensing one component of the drug, the next component of the drug will be condensed, which will affect the subsequent detection effect of the drug due to the existence of other components in the condensing chamber of the condensing hopper.
