Extraction and reverse osmosis device for traditional Chinese medicines

Abstract

The invention relates to an extraction reverse osmosis device for traditional Chinese medicines. The extraction reverse osmosis device comprises a plurality of reverse osmosis tanks which are connected in series; each reverse osmosis tank is provided with a feeding port, a residual liquid discharge port and a leachate discharge port; the feeding ports are communicated with a feed pipe; the residual liquid discharge ports are communicated with a residual liquid discharge pipe; the leachate discharge ports are communicated with a leachate discharge pipe; a plurality of hollow fiber reverse osmosis membranes are arranged in each reverse osmosis tank; hollow parts of all the hollow fiber reverse osmosis membranes are communicated with the leachate discharge pipe; and the feed pipe and the residual liquid discharge pipe are communicated with spaces, outside the hollow fiber reverse osmosis membranes, in the reverse osmosis tanks. The extraction reverse osmosis device for the traditional Chinese medicines has the advantages that a large number of hollow fiber reverse osmosis membranes are arranged, so that reverse osmosis treatment is carried out on a traditional Chinese medicine extracting solution, and the treatment process is simple and efficient.

Description

technical field [0001] The invention relates to the technical field of extracting traditional Chinese medicines, in particular to a reverse osmosis device for extracting traditional Chinese medicines. Background technique [0002] The reverse osmosis device passes the raw water through a fine filter, granular activated carbon filter, compressed activated carbon filter, etc., and then pressurizes it through a pump. / 300) of the reverse osmosis membrane (RO membrane), so that the higher concentration of water into low concentration water, and at the same time isolate industrial pollutants, heavy metals, bacteria, viruses and other impurities mixed into the water, so as to achieve the physical and chemical requirements of drinking Indicators and hygienic standards, the output is clear and pure water. [0003] The reverse osmosis membrane in the prior art is an artificial semipermeable membrane with certain characteristics, which is made by simulating a biological semipermeable...

AI Technical Summary

Problems solved by technology

When using the reverse osmosis device in the prior art to filter the Chinese medicine extract, the reverse osmosis membrane is prone to clogging, which is not easy to clean and needs to be replaced frequently

Existing reverse osmosis devices are not suitable for the filtration treatment of traditional Chinese medicine extracts in industrial production
