Extracting mode nine: use first extractor and second extractor to carry out continuous adverse current type and extract, during use, open first switch valve, the 3rd switch valve, close the second switch valve, the 4th switch valve, the 6th switch valve, the 7th switch valve, the 8th switch valve, the 9th switch valve, the tenth switch valve, the 11 switch valve, twelvemo is closed valve, the 13 switch valve, the 14 switch valve, eighteenmo closes valve, material is inserted in second extractor, solvent is inserted in first extractor, open the heating of first extractor, make solvent vapo(u)r enter into second extractor bottom and upwards penetrate material from the below through second arm from first extractor, solvent vapo(u)r and then enter condensation in the condenser through the 3rd arm with the 8th arm, solvent enters gravity tank through the 4th arm after the condensation, when treating that gravity tank has a certain amount of solvent, perhaps directly add a certain amount of solvent from the gravity tank top, open the 6th switch valve, the 8th switch valve, make gravity tank liquid flow back to second extractor through the 7th arm with the 5th arm, regulate the high-order tank level of the 6th switch valve flow-control and be in certain altitude, make solvent gas, liquid can guarantee circulation.The liquid flux that refluxes flows downward from second extractor material top, lixiviate material from top to bottom, the final liquid solvent is back to first extractor through second arm, and so forming a dynamic circulation can constantly leach material active ingredient and bring in first extractor.This extracting mode is the gas-liquid-solid three-phase extraction, wherein solvent gas-liquid two-phase adverse current enters second extractor, liquid flux carries out lixiviate to material from top to bottom, solvent vapo(u)r adds gentle the stirring to material from bottom to top, and liquid flux had the drag force effect, the time of staying that both influence liquid phase jointly distributes.When keeping material and solvent concentration difference, increase the time of contact of solvent and material, increased the leaching effect of active ingredient in the material.By regulating the folding degree of temperature and related valve, the flow velocity of solvent vapour is increased to can stop downward liquid flow, form liquid flooding, can realize the liquid flooding extraction method this moment.The liquid that condensation this moment is got off, the gas that constantly upward steams mix fully with medicinal material, and whole system is in turbulence state, have strengthened solvent to the infiltration of material and the renewal of promotion two-phase, can obviously improve extraction efficiency.In leaching process, can open eighteenmo at the tenth arm place and close valve sampling detection, the transfer case of active ingredient in the dynamic monitoring leaching process.After extract finishing, can continue in first extractor, to concentrate and in gravity tank through the 6th arm recovery solvent.
Extracting mode ten: in above-mentioned each extracting mode, decompressor such as external vavuum pump is realized methods such as decompression is extracted, decompression concentrates as the case may be; lower the boiling point of solvent; accelerate the recovery of solvent, cut down the consumption of energy, the thermally labile component in the protection extract.
Extracting mode 11: in above-mentioned each extracting mode, pressue device such as external peristaltic pump as the case may be, realize methods such as high pressure extraction, super-pressure extraction, the influence to the raw cell broken wall when utilizing high pressure conditions to the influence of the infiltration of solvent and pressure release realizes fast, efficiently, the extraction of low energy consumption, low impurity content.
As optimization, position, the described second extractor inner chamber middle and lower part also is provided with sieve tray.Like this, when using second extractor to extract, material can be placed on the sieve tray, prevents that material from stopping up the outlet that the tank body lower end is connected with second arm.
As further optimization, the described second extractor inner chamber middle and upper part also is horizontally disposed with a detachable dividing plate, is evenly distributed with some through holes on the described dividing plate.Described detachable being meant is detachable the connection between dividing plate and the second extractor inner chamber, for example directly one circle boss is set, is shelved on the boss when making dividing plate use, a holder perhaps is set at tank inner chamber, when needing to use dividing plate, dividing plate is held fixes.After being provided with like this, in each extracting mode, when using second extractor to extract and being attended by solvent refluxing, can after installing, material again dividing plate be loaded onto, like this, the solvent that refluxes through the 7th arm can down flow to material equably behind dividing plate, guarantee to extract uniformity, shortens extraction time, improves extraction efficiency.
As the further optimization of aforementioned barriers structure, the part through hole is to being provided with short tube as crossing tracheae in the described dividing plate, and all the other through holes are crossed tracheae and flow tube and evenly distributed to being arranged with short tube as flow tube.Like this, in extracting mode nine, the air-flow that rises in second extractor can pass through from crossing tracheae, and dirty liquid can pass through from flow tube.Before doing this optimization improvement, the applicant finds that even be provided with dividing plate, the material extraction effect does not still reach the degree in the imagination, and extraction effect is still very inhomogeneous.The applicant further researchs and analyses discovery, even be provided with dividing plate, big quantity of fluid still can be from the dividing plate flow into the below with the through hole of the adjacent side of the 7th arm interface, and most gases blocked by liquid in this side can only be from opposite side up, so the gas-liquid skewness causes the inhomogeneous of medicine extraction and then has influenced whole extraction effect.Applicant Ceng Xiang crosses and reduces through-hole diameter and make liquid show on the whole dividing plate of uniform arrival, but causes the too small feasible below of through-hole diameter gas to be blocked by liquid so again and can't appear through hole.Final applicant creatively is provided with flow tube and crosses tracheae, makes gas-liquid two-phase be evenly distributed in the solids bed of material, strengthens mass-transfer efficiency.After improving like this, the flow tube diameter can be provided with lessly, guarantee to be distributed in behind the dividing plate table again toward dirty from the liquid that the 7th arm flows out, below gas from cross tracheae by dividing plate can avoid by liquid block cause be difficult to by.Liquid also can become more even because of the tracheae shunting of crossing that is made progress when surface low is moving on dividing plate simultaneously.Thereby farthest guaranteed the uniformity that liquid is dirty.And then fully guaranteed extraction effect.Can install simultaneously a circle sealing baffle further at the edge of dividing plate additional, prevent wall stream effect.
As another optimization, described siphon pipe adopts transparent pipeline, also is communicated with between siphon pipe and the drainer upper end to be provided with the 14 arm, and described the 14 arm is provided with sixteenmo pass valve.Like this, when needs, sixteenmo can be closed valve and open back usefulness, siphon pipe be made liquid level gauge use; Get final product when directly closing sixteenmo pass valve when not required.
As another optimization, also be provided with the twelve earthly branches pipe, described twelve earthly branches Guan Yiduan is connected on the 9th arm between the 4th switch valve and the gravity tank, and the other end is connected on the 5th arm between the 6th switch valve and the 7th arm; Described twelve earthly branches pipe is provided with the 5th switch valve.This be because, in modes such as extracting mode three, four, five, nine, need to regulate the gravity tank liquid level and remain on certain position, thereby rely on high-order pot liquid deadweight, guarantee that whole vapour, liquid circulation direction according to the rules normally carry out.And make the gravity tank liquid level keep certain level is to guarantee by the flow of regulating the 6th switch valve.But because in the leaching process, the different phase solvent evaporation amount is different.Event might cause high-order tank level to increase gradually and then overflow, and perhaps liquid level is reduced to zero and then the influence circulation gradually.So the applicant has creatively set up the twelve earthly branches pipe, after improving like this, can must be as far as possible little in above-mentioned control procedure with the 6th switch valve flow-control, and liquid level goes up and can be spilled over to the 5th arm of below from the twelve earthly branches pipe to the 9th arm place in the gravity tank.So can guarantee that the liquid level of gravity tank can be precisely controlled.Guaranteed normally carrying out of circulation.When not needing to use the twelve earthly branches pipe, only need close the 5th switch valve and get final product.
As one optimizing again, also be provided with the 13 arm, described the 13 arm one end is connected on the 5th arm between the 11 switch valve and the 9th switch valve, and the eighteenmo that the other end is connected on the tenth arm closes between the valve and second arm; Described the 13 arm is provided with the tenth switch valve.Like this, in extracting mode four and five, can close the 8th switch valve, open the 9th switch valve and the tenth switch valve, the liquid that other gravity tank refluxes diverted via the 5th arm, the 13 arm and second arm and gets back in second extractor under the deadweight effect, and below second extractor, up go out, material in second extractor is played stirring action, further strengthen extraction effect.
In sum, compared to existing technology, the present invention has only adopted a set of equipment, and a spot of several tank bodies can be realized the execution of multiple extracting mode by the switching between different arms and the switch valve; Also be convenient to mutually combining and adjusting of various extraction means simultaneously, realized the flexible adjustability of extracting mode.Need to adopt separately a set of equipment compared with a kind of extracting mode in the prior art, this combined type extraction system has improved the applicability of equipment, increase utilization rate aborning, reduced enterprise in the soil, the input cost of aspects such as building, equipment.Simultaneously, because the co-operating of various combined type extracting modes has improved production efficiency greatly in the applicability that improves equipment.In addition, the present invention optimizes the additional structure of part, and the corresponding difficult problem in the time of also can solving practical operation makes extraction more efficient.
