Supercritical extraction technique is advanced Chinese medicine extraction technology, and Chinese patent 97231194.7 discloses a kind of counter-current extraction tower of supercritical carbon dioxide extraction 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 allotter, 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, allotter and residual liquid 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 commercial production.
Summary of the invention
Technical problem to be solved in the utility model 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, filter pressing.
The technical scheme in the invention for solving the above technical problem is: this Chinese medicine continuous countercurrent extraction device, comprise casing, base, its construction features 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 the intravital a pair of reverse rotation of case 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 body and extractant reaches very high efficient.The pitch of flight does not wait and is more conducive to filter pressing and discharge.Finish conveying for first section of screw rod, finish stirring, reflux extraction for second section, finish filter pressing and discharge for the 3rd section.Screw rod is installed in the casing, guarantees the sealing of material.
Screw rod described in the utility model 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 described in the utility model 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 described in the utility model can be regulated in 0～10 °.
The parts that casing described in the utility model, screw rod, flight contact with material adopt the nonmetallic materials of rustless steel and the medium of anti-the material to make.The nonmetallic materials of rustless steel and the medium of anti-the material can guarantee the cleannes of material.
This utility model 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 Chinese medicine extraction of filter pressing.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 extraction simultaneously, solve the cost of extracting technique of Chinese medicine and the contradiction between the efficient, for the Chinese medicine extraction facility modernization provides the common technology platform, drive the development of Chinese medicine plantation and preparation industry.
