Description
Technical field
The utility model relates to a kind of high-efficiency device for extracting, is specifically related to utilize solvent to extract the high-efficiency device for extracting of the material that can be dissolved in this solvent from material.
Background technology
Can be by the composition of certain dissolution with solvents for from material, extracting, at present extracting method commonly used has the conventional arts such as decocting method, circumfluence method, infusion process, percolation, and the new extractive techniques such as supercritical extract, supercritical ultrasonics technology, microwave method, half biomimetic method, enzymology method.Employed extraction element is mainly apparatus,Soxhlet's, soaks the tank of filtering, extractor or reactor etc., and these extraction elements are all existing some problems in varying degrees.
Apparatus,Soxhlet's is classical extraction element, and it utilizes repeats refluxing extraction, after finishing a solvent extraction, solution is heated, and the solvent of volatilization reenters the environment of extraction through condensing tube condensation, the new leaching process once of beginning, so circulation is gone down, until stop to extract.This saves solvent than directly extracting with solvent refluxing, also save the time of a lot of later stages removal solvents, but owing to need distill repeatedly, required extract that reasonable stability is arranged, and the solvent extraction material is to carry out under the condition of static state, and extraction efficiency is lower.
Soaking the tank of filtering, is a kind of extraction equipment of filtering that typically soaks, and solvent adds from tank body top, discharges from the bottom after the medicinal material in the tank is extracted, and the extract quality that obtains is good, impurity is few, it is high to extract yield; Equipment simply is easy to make and safeguards.But there are the problems such as rate of extraction is slow, solvent load is large, production efficiency is low, energy consumption is large.
Extractor is to use maximum extraction equipments.Heat the material that is immersed in the solvent with jacket steam, soak extraction.Except the extraction that is fit to heat, can also utilize the volatile oil in the airtight condenser system recovered material; Can improve when adopting secondary or three grades of cross current solvent extraction technique and extract yield.Shortcoming is that material component can't rapidly and efficiently enter in the solvent, and solid matter hinders heat transfer efficiency, and material is difficult to fully well-done, so that extraction efficiency descends.
Means of supercritical extraction is the new extraction process of developing in recent years.The advantage of supercritical extract be selective strong, extract purity is high, is suitable for extracting from solid material the lipophilic substance of known chemical structure, molecular weight.Shortcoming be operating pressure high, have security risk, energy consumption is large, cost is high, is not suitable for extracting the not clear mixture of composition and the less material of solubility in carbon dioxide.
Ultrasonic wave extracts the energy enhanced dispersion process that can utilize ultrasonic vibration, makes solvent immerse easily solid, and solid solute is diffused into solid liquid interface from solid interior easily, thereby has accelerated extraction process.Independent ultrasonic wave extraction equipment does not have to reflux and concentrated function, and the device structures such as picture ultrasonic wave counter-flow extraction are complicated, cost is high.Microwave Extraction utilizes microwave to effect heated solvent and the medicinal material of polar molecule, makes cell wall rupture, reaches the purpose of accelerating extraction.But Microwave Extraction Equipment exists and the same problem of ultrasonic equipment, has limited further applying of this kind equipment.
This extraction element is simple in structure, and low cost of manufacture has significantly been saved solvent load by solvent refluxing, simultaneously, and owing to the saturated problem that extraction efficiency is reduced of extraction of substance in the solvent has been avoided in the continuous backflow of fresh solvent.The effect of ultrasonic wave and microwave has guaranteed the high efficiency of extracting in leaching process.Use this device to extract, possess small investment, cost is low, and the characteristics that safe coefficient is high can realize efficient, rapid extraction to the composition that is dissolved in specific solvent in the material.
Summary of the invention
The utility model is for the deficiency of present extraction element, provide a kind of simple in structure, cost is low, solvent load is few, extraction efficiency is high, high-efficiency device for extracting safely and fast.
The utility model is comprised of rotary evaporation bottle, condenser, extractor.
The rotary evaporation bottle is arranged in the utility model device, and the rotary evaporation bottle is furnished with heater, and rotary evaporation bottle and whirligig are tightly connected and can dismantle.The filling opening valve of whirligig top can add solvent and control vacuum.
Condenser of the present utility model is connected with rotary evaporation bottle and extraction vessel, is provided with the pipeline that is connected with negative pressure system at the top.The condenser lower channel is led to extractor, makes condensed solvent enter extractor and again extracts composition in the material.
Extraction vessel in the utility model is the extractor that can change, has two kinds of extractors standbyly to use, and a kind of is to be furnished with ultrosonic extractor, and another kind is furnished with microwave generating apparatus.These two kinds of extractors can be realized to the control of ultrasonic wave or microwave power with to the control of material in tank temperature by the control panel on the extractor.Filter screen and filter bag are arranged in the extractor, material is contained in the filter bag, and extractor top and condenser are tightly connected, and condensed solvent enters filter bag in the extractor by pipeline, there is the siphon return duct at 2/3rds places at the bottom of the tank at tank body, enter the rotary evaporation bottle from the whirligig top.
Extractor of the present utility model is connected by the siphon return duct with the rotary evaporation bottle, and the siphon return duct is provided with valve, when extract finishing, when extract is concentrated or uses separately as Rotary Evaporators, can close this valve.
The utlity model has following advantage:
1, this device guarantee efficient, fast, under the prerequisite extracted of safety, reached that device structure is simple, low cost of manufacture, use flexibly, the purpose of easy operating.
2, the solvent of this device lixiviate material is a continuous circulation process, and the solvent that enters extractor all is the fresh solvent that does not contain extract, overcome owing to the saturated shortcoming that extraction effect is reduced of material in the solvent, because the use of ultrasonic wave and microwave, in solvent refluxing, accelerated the speed of material to sovent diffusion, improve extraction efficiency, reduced the use amount of organic solvent.
3, along with the carrying out of leaching process, extract is enriched in the rotary evaporation bottle, and extraction and concentration carries out synchronously, has reduced labour intensity.
This device can be used as Rotary Evaporators and uses separately when 4, closing valve on the siphon return duct.
5, negative pressure device can be implemented in temperature and extracts than under the low condition, has avoided high temperature to extracting the destruction of composition.Extractor can be realized can satisfying the requirement of different process to the control of ultrasonic wave or microwave power and to the control of temperature of charge.
