Problems solved by technology

[0003] The existing supercritical extraction equipment has low mixing efficiency, unstable separation efficiency after extraction, and low efficiency, resulting in the need for multiple repeated extractions, which seriously affects production efficiency; the existing equipment only reduces the temperature of carbon dioxide through a general condensing tube, so that The extraction liquid is separated, the separation efficiency is slow, and during the operation of the cooling box, the cooling box vibrates, affecting the normal working efficiency of the cooling box, resulting in unstable operation of the cooling box, resulting in the occurrence of accessories falling off, and affecting its service life; and Generally, the working pressure is relatively high. The existing equipment is equipped with a pressure relief valve on the pipeline for pressure relief. The operation is cumbersome, and it is easy to cause misoperation, low safety performance, and easy to cause safety accidents.

Abstract

The invention discloses a drug extraction device for biomedicine. The device comprises a tank body and a shell, wherein one side of the tank body is connected with a communicating pipe, the other endof the communicating pipe is connected with the shell, the communicating pipe is provided with a plurality of branch pipes, and a plurality of aeration ports are formed in the branch pipes; a coolingbox is arranged in the shell, a condensation pipe is arranged in the cooling box, a discharge port is formed in the bottom of the cooling box, and the discharge port is an extract liquor discharge port; the communicating pipe is communicated with the cooling box; a clamping mechanism is arranged at the bottom of the cooling box; a safety mechanism is arranged at the top of the shell; the communicating pipe is provided with a plurality of aeration ports, so that the contact area of the supercritical gas and the extraction liquid is increased, the mixing rate of the supercritical gas and the extraction liquid is increased, and the extraction effect is improved; and by arranging a safety mechanism, safe pressure relief is achieved, and the use safety of the equipment is improved.

Description

technical field [0001] The invention belongs to the field of extraction, and in particular relates to a drug extraction device for biomedicine. Background technique [0002] The difference in solubility or partition coefficient of a substance in two immiscible (or slightly soluble) solvents is used to transfer a substance from one solvent to another. After repeated extractions, most of the compounds are extracted; when extracting drugs, supercritical extraction is often used, and the drugs are soaked and then poured into the extraction tank, and a supercritical fluid, usually carbon dioxide, supercritical A fluid is a state of matter that is neither a gas nor a liquid between gas and liquid. This substance can only exist when its temperature and pressure exceed the critical point. The density of supercritical fluid is higher, similar to that of liquid, and its viscosity is closer to that of gas. Therefore, supercritical fluid is a very ideal extraction agent. [0003] The...
