Description

A kind of high-efficiency device for extracting

Technical field

The present invention relates to a kind of device, especially a kind of high-efficiency device for extracting belongs to material extractive technique field.

Background technology

Usually, the extraction of material, especially the extraction of plant, all be material to be carried to be immersed in one be equipped with in the container such as extractor that extracts solvent, after soaking certain hour, isolated by filtration extract and soak slag, soak, extract repeatedly so repeatedly after, merge extract, namely obtain the extract of required active ingredient.For example Chinese patent ZL96210476.0, ZL200520022234.2 all adopt the static immersing extracting mode to extract active ingredient in the Chinese medicine.Because in the static immersing extracting mode, botanical drug substance is insufficient with contacting of extraction solvent, so extracting cycle is long, extraction efficiency is low, is subjected to the restriction of TPT in addition, can not infinitely prolong soak time, therefore, many active ingredients in the actual production in the botanical drug substance may not all be extracted, and not only waste is big, but also directly influence the medical value of extract.In order to improve extraction efficiency, prior art adopts following certain methods: (1) is the design paddle in the middle of tank body, botanical drug substance is fully contacted with the extraction solvent, as Chinese patent ZL96228716.4, agitator has been installed in tank body exactly, by the stirring of agitator, when soaking, increase botanical drug substance and the relative motion of extracting solvent, finally improve extraction efficiency.Go a step further before adopting this mode than static immersing, but because some botanical drug substances are lighter, always swim on the liquid level that extracts solvent, even adopt agitator that this part material is fully mixed with the extraction solvent, its extraction efficiency is still unsatisfactory; (2) tank body is designed to rotating spheroid, as Chinese patent ZL88213266.0, increase botanical drug substance and the relative motion of extracting solvent by rotatablely moving of spheroid jar, but the spheroid jar is subjected to it to support the restriction of turning cylinder, be difficult for making the large scale tank body, and the input and output material inconvenience, thereby in large-scale production, seldom adopted by producer.Along with the continuous rising of botanical drug substance cost, each producer all has higher requirement to extraction efficiency, is badly in need of a kind of efficient immersion and extracts equipment.

Summary of the invention
