Description
Technical field
The present invention relates to a kind of counter-current extraction device, particularly a kind of Chinese medicine continuous countercurrent extraction device, the extraction that is used for Chinese medicine separates, and can be according to different extract by adopting different extraction process is realized continuously, counter-current extraction efficiently.
Background technology
Traditional Chinese medicine extraction isolation technics and equipment, most important to utilization rate and the result of treatment that improves Chinese medicine.Traditional traditional Chinese medicine extraction mainly adopts decocting method, hydrodistillation, solvent extraction method etc.This extracting method is easy and simple to handle, is not very high to the requirement of technology, equipment, therefore uses comparatively extensive.But also there are some shortcomings in it, and the active ingredient extraction rate that contains in more impurity, the medicinal material in, the extract long such as extraction time is lower, and feeding an one-step refining makes troubles.The modern Chinese herbal medicine extractive technique mainly contains dynamic countercurrent extraction, supercritical extract, macroporous resin adsorption extraction and ultrasonic wave extraction etc., compare with traditional extracting method, the dna purity of active ingredient is higher in the modern Chinese herbal medicine extractive technique Chinese medicine, method is more easy, for optimizing form of Chinese drug and technology, become " effectively crude extract " into " effectively extract ", favourable technical support is provided.
Supercritical extraction technique is advanced traditional Chinese medicine extraction technology, and Chinese patent 97231194.7 discloses a kind of counter-current extraction tower of supercritical carbon dioxide extracting vitamin E.This extraction tower is made up of top of tower, body of the tower and tower bottom; Top of tower has products export, loam cake, feed(raw material)inlet, product reflux mouth and distributor, and body of the tower is divided into upper and lower two joints, be provided with chuck, hot water gateway, tower body, flange, microwell plate, micropore plate holder and triangle filler, be provided with CO2 inlet, distributor and raffinate outlet at tower bottom.Owing to be continuous countercurrent operation, changed the intermittently following current operation of original void tower, so extraction efficiency, all raisings greatly of product purity.Supercritical extraction unit but exists a root problem, is the sealing, the leakage problem investment cost costliness that solve equipment under the high pressure, has influenced the extensive popularization in the Chinese medicine industrial production.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of and can overcome the defective that prior art exists, and realizes incorporate efficiently, the Chinese medicine continuous countercurrent extraction device cheaply of stirring, mixing, conveying, press filtration.The present invention addresses the above problem the technical scheme that is adopted: this Chinese medicine continuous countercurrent extraction device, comprise casing, base, its design feature is: the parallel screw rod that a pair of reverse rotation is installed in the casing, be fixed with flight on the screw rod, have return port on the described flight, the pitch of flight does not wait, and described screw rod two ends are loaded on the tank ends face respectively, the one end connects motor.The screw rod that is installed in a pair of reverse rotation in the casing can be finished conveying, stirring, mass transfer, the heat transfer of material.The return port that has on the flight, flight can mix the stirring material again by convey materials when screw rod rotates, and makes mass transfer and heat transfer more abundant, and the reaction of powder and extractant reaches very high efficient.The pitch of flight does not wait and is more conducive to press filtration and discharge.Finish conveying for first section of screw rod, finish stirring, reflux extraction for second section, finish press filtration and discharge for the 3rd section.Screw rod is installed in the casing, guarantees the sealing of material.
Screw rod of the present invention links to each other with the motor that speed regulator is housed by shaft coupling, and shaft coupling, speed regulator and motor all are positioned at outside the casing.The power of screw rod is provided by the motor that speed regulator is housed, can be according to the rotary speed of different extraction process adjusting screw(rod)s.
Casing of the present invention is fixed on mainly on the base that is made of fixed support and lifting support, and the horizontal tilt angle of casing is regulated by lifting support.Angle of inclination by casing is regulated, and can control the flow velocity of extractant and the extractant liquid level height at casing, to guarantee higher extraction efficiency.
The horizontal tilt angle of casing of the present invention is regulated in 0～10 °.
Casing of the present invention, screw rod, flight adopt the nonmetallic materials of stainless steel and the medium of anti-the material to make.The nonmetallic materials of stainless steel and the medium of anti-the material can guarantee the cleannes of material.
The present invention compared with prior art has the following advantages and useful effect: 1, this Chinese medicine continuous countercurrent extraction apparatus structure is reasonable, design a pair of reverse rotation, that be fixed with the screw rod of taking back the flight that discharge orifice and pitch do not wait is installed in the casing of extraction equipment, can realizes stirring, mixing, conveying, incorporate efficient, continuous, the safe traditional Chinese medicine extraction of press filtration.2, this extraction equipment is simple in structure, low cost of manufacture, can solve the poor efficiency that herbal pharmaceutical industry takes the extraction of traditional immersion type and the problem with high investment of supercritical extract simultaneously, solve the cost of extracting technique of Chinese medicine and the contradiction between the efficient, for the traditional Chinese medicine extraction facility modernization provides the common technology platform, drive the development of Chinese medicine plantation and preparation industry.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Example structure is referring to Fig. 1, Fig. 2.
This Chinese medicine continuous countercurrent extraction device comprises casing 15 and base 17, and base 17 mainly is made up of fixed support 1 and lifting support 10, and casing 15 is loaded on the base.The horizontal tilt angle of casing 15 can be regulated in 0～10 ° by lifting support 10.The parallel screw rod 13,14 that a pair of reverse rotation is installed in the casing 15.Be fixed with flight 16 on the screw rod 13,14, the pitch of flight 16 does not wait.Have return port on the flight 16, have three return ports on the every flight 16 of embodiment.Screw rod 13,14 two ends are loaded on respectively on the both ends of the surface of casing 15, and the one end links to each other with the motor 4 that speed regulator 3 is housed by shaft coupling 5, and the rotary speed of screw rod 13,14 can be regulated by speed regulator 3.Shaft coupling 5, speed regulator 3 and motor 4 all are positioned at outside the casing 15, and speed regulator 3 is fixed on the base 17.The parts that casing 15, screw rod 13,14, flight 16 contact with material adopt the nonmetallic materials of stainless steel and the medium of anti-the material to make.
