Description

Technical Field

[0001] The utility model relates to a drug liquid extraction and distillation device. Background Art

[0002] Distillation is a thermodynamic separation process. It uses the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling-point component and then condense it to separate the entire component. It is a unit operation process of evaporation and condensation. Compared with other separation methods, such as extraction, filtration and crystallization, its advantage is that it does not require the use of other solvents other than the system components, thereby ensuring that no new impurities are introduced. Different components of liquid have different boiling points, which is the most basic theoretical basis for distillation. At the same temperature, the single-phase liquid of the vapor of each component above the liquid, when the mixed liquid composed of liquid A and B in a certain proportion (assuming that the concentration of A is c1) reaches the boiling point line after heating, and then through the indifferent gas-liquid equilibrium (from 1 to 2), a mixed gas with an A content of c2 is obtained in the generated gas phase; the gas is cooled and condensed and collected to obtain a liquid with a new composition (A concentration is c2).

[0003] The extraction and distillation of medicinal liquid is a method of using the distillation process to obtain the required components in the medicinal liquid. In the authorized Chinese utility model patent "Announcement No.: CN209270875U, Name: A distillation device for Chinese medicine extraction", it uses a filter to filter the medicinal residue, and the distillation effect is obvious. However, the filter in the above application relies on the gravity of the medicinal liquid to filter the medicinal residue, and the filtering effect is low. In addition, the filter is arranged at the upper end of the equipment and is on the outside of the equipment, in direct contact with the external environment, resulting in external dust and other impurities easily entering the medicinal liquid, and the heat during distillation is easily dissipated to the outside through the filter, resulting in low distillation efficiency and energy waste. At the same time, the medicinal liquid with a low boiling point in the above application generates steam that is discharged through the exhaust pipe and condensed and collected by an external condensation device, that is, an external condensation device is required to realize the overall medicinal liquid extraction and distillation process, resulting in a large equipment footprint and high cost of use.
