Abstract
The utility model relates to a solvent extraction device, particularly to an ultrasound-assisted supercritical fluid extraction kettle for active ingredients of traditional Chinese medicines, which comprises a kettle body (1) and an ultrasonic vibrator (4); and is characterized in that the ultrasonic vibrator (4) is arranged at the bottom of the kettle body (1), and an amplitude transformer (4-1) of the ultrasonic vibrator (4) is extended into the kettle body (1) from the bottom of the kettle body (1). The extraction kettle provided by the utility model can be used for extracting active ingredients from traditional Chinese medicinal raw materials by virtue of carbon dioxide (CO2), nitrogen gas (N2), nitrous oxide (N2O), ethylene (C2H4), trifluoromethane (CHF3) and other supercritical fluids.
Description
Technical field
The utility model relates to solvent extraction plant, is specifically related to a kind of supercritical fluid extraction equipment of solid matter.
Background technology
The modernization of Chinese medicine industry often relies on the modernization of technology and equipment to a certain extent.The supercritical liquid extraction technique of developed recently is used for extracting the active ingredient of natural drug, be particularly suitable for damp and hot unsettled material is extracted, noresidue solvent and reclaim the defective that solvent causes environmental pollution, and extraction rate again is fast, can shorten the production cycle.But, the supercritical fluid extraction still is a kind of high-pressure bottle, whole extractive reaction process must be carried out in the system of good airproof performance, therefore the device (as powerful agitating device) of strengthening extraction reaction just is difficult to combination with it in the traditional handicraft, therefore, can only improve effect of extracting by the method for control temperature or pressure according to the difference of the solubility of the thing of waiting to come together.Yet the change of temperature or pressure is limited for the stripping of the thing that quickens to wait to come together and the effect that further improves the defecation degree.
Publication number is that the application for a patent for invention of CN101579583A discloses a kind of " ultrasound-enhanced supercritical or Asia critical fluids extraction equipment ", this device comprises extraction kettle, ultrasonic transducer, the luffing bar, the luffing bar is installed on the extraction kettle with its node place, it is characterized in that described ultrasonic transducer is positioned at outside the extraction kettle, luffing bar one end is connected with ultrasonic transducer, and the other end puts in the extraction kettle.The technical scheme of foregoing invention patent application has been summarized ultrasonic vibration and has been arranged on the extraction kettle scheme at any position outward, but only disclose the scheme that ultrasonic vibration is located at the extraction kettle top in its specification, had no way of finding out about it and ultrasonic vibration is located at the scheme public at other position of extraction kettle.As everyone knows, ultrasonic vibration of this band luffing bar, if ultrasonic vibration does not directly contact with working media especially entrainer, its efficient will significantly reduce, also just because of above-mentioned reason, described patent scheme is extended a tool heads downwards at the end face of luffing bar, utilizes described tool heads to cause in the extraction kettle ultrasonic.Yet, the structure of the luffing bar in ultrasonic vibration and shape will be according to transducer amplitude and accurately designs of frequency, the changing a little of its structure, shape and material just can't guarantee the luffing bar intrinsic frequency equate with Frequency for Ultrasonic Energy Transducer, that is can't make it be in resonance state, also just can't play the amplification of amplitude.Therefore, the negative interaction of the described tool heads of application for a patent for invention of CN101579583A is predictable.By the situation of above-mentioned prior art as seen, seek ultrasonic vibration best site of son and mounting means,, further improve supercritical fluid extraction equipment efficient and have great importance for both available energies of giving full play to ultrasonic vibration.
Summary of the invention
In view of there is above-mentioned deficiency in prior art, technical problem to be solved in the utility model provides a kind of improved ultrasound-enhanced supercritical fluid extraction still.
The body technique scheme that the utility model solves the problems of the technologies described above is as described below:
A kind of ultrasound-enhanced supercritical fluid extraction still of effective components of Chinese medicinal, this extraction kettle comprises kettle and ultrasonic vibration, it is characterized in that described ultrasonic vibration is installed in the bottom of kettle, its luffing bar is put in the kettle by the bottom of kettle.
The concrete mount scheme of ultrasonic vibration described in the utility model is, the bottom thread connection one of kettle has the plug screw of centre bore, the middle part of the centre bore of described plug screw is provided with a step, the transducer of ultrasonic vibration passes described centre bore from top to bottom, the ring node at its middle part is conflicted and on the set step, is compressed by a pressure ring that is threaded in the described centre bore in being located at centre bore.
For fear of seepage, between the upper and lower end face of the ring node at ultrasonic vibration described in the utility model middle part and the pressure ring and be equipped with sealing ring between plug screw and the kettle.
In order to control the extractive reaction temperature, extraction kettle described in the utility model also comprises the recirculated water chuck that is located at the kettle periphery.
The ultrasound-enhanced supercritical fluid extraction still of effective components of Chinese medicinal described in the utility model can be used for using the effective ingredient in carbon dioxide (CO2), nitrogen (N2), nitrous oxide (N2O), ethene (C2H4), the fluoroform supercritical fluid extraction Chinese medicine materials such as (CHF3).
Because technical scheme described in the utility model, wherein, ultrasonic vibration is installed in the bottom of kettle, its luffing bar is put in the kettle by the bottom of kettle, therefore the luffing bar of described ultrasonic vibration can fully directly contact with needed supercritical fluid of extractive reaction and entrainer, the ultrasonic wave that ultrasonic vibration is produced produces distinctive " cavitation effect " in liquid medium, constantly produce countless internal pressures and reach thousands of atmospheric little air pockets, and the strong shock wave that continuous " microexplosion " produces on the microcosmic acts on solid-liquid or the liquid-liquid molecule, air in the medium is overflowed by " bombardment ", and impel the material in medium cell rupture and the distortion accelerating medium molecule to overflow, further strengthen and improve the supercritical fluid extraction process, significantly improve efficient and defecation degree.
