Abstract
The utility model relates to a multi-stage spiral continuous countercurrent leaching device used for leaching active ingredients out of natural products (particularly traditional Chinese medicinal materials), and belongs to the technical field of extraction of Chinese traditional medicine. Aiming at the defect that non-interstage solid-liquid separation or interstage solid-liquid separation in the prior art is not thorough, the multi-stage spiral continuous countercurrent leaching device is characterized in that material conveying ends among multiple sections of machine grooves provided with a heating component and/or an ultrasonic wave component are connected with input ends in parallel end to end in a roundabout manner through an oblique conical spiral conveying and extruding machine, are communicated with material countercurrent solvents or solutions through liquid transport pipelines with liquid level differences, and extracted liquid at each stage can be completely separated from the medicinal materials as much as possible. On the premises of energy conservation and consumption reduction, compared with the prior art, the multi-stage spiral continuous countercurrent leaching device significantly improves the leaching rate and increases the yield.
Description
Technical field:
The utility model relates to a kind of multiple coil formula continuous countercurrent leaching device that active ingredient in natural products (especially Chinese medicine) is leached, and belongs to traditional Chinese medicine extraction technical field.
Background technology:
Under heating and/or ul-trasonic irradiation, multiple stage continuous adverse current extract technology is to improve leaching rate, yield and quality, energy-saving consumption-reducing, the effective way of minimizing operating cost.In leaching process, the completeness of every grade of Separation of Solid and Liquid is very important.After every grade of leaching completes, the ratio of this active ingredient amount in the active ingredient amount in spice and leachate, has material impact to leaching yield.If after leaching, Separation of Solid and Liquid is not thorough, can affect this ratio, thereby affects yield.Separated just had certain upper level active ingredient concentration after thoroughly also can not making fresh solvent that rear one-level adds or solution rigidly connect to touch medicinal material, to liquid-solid equilibria to leaching the movement of direction or the increase of leaching rate is all disadvantageous, therefore after every one-level has leached, should allow the leachate of every one-level completely separated as much as possible with medicinal material.
By producer's several extractors of employing, formed the multilevel counter-flow extraction technique of " adverse current tank group ", can limited raising yield.But still be static intermittently operated, after every one-level has leached, while emitting leachate, to give long time and make leachate as far as possible separated with medicinal material, this is both consuming time also not exclusively separated.The patent No. is that the patent of 002119080.X discloses a kind of spiral continuous countercurrent leaching device with heater and/or ultrasonic wave member, arrangement form is the horizontal head and the tail serial connections in one line of several sections of troughs, the conveyor screw of trough is only promoted by a driving mechanism, the major axis of serial connection is subject to compression, if operation be obstructed, major axis because of compression is excessive will " rod member unstability ", cause bending, even fracture, and complete machine is long to workshop layout, unfavorable to operating, clean, keeping in repair.Though this dynamic countercurrent leaches, effect is better relatively, although formed by more piece trough serial connection, but in technique, be still one-level continuous reverse flow leaching, there is no Separation of Solid and Liquid program therebetween, have back-mixing (leachate that is different levels variable concentrations in leaching process mixes mutually), back-mixing can affect the raising of leaching effect.
Summary of the invention:
The purpose of this utility model is to provide a kind of at apparatus arrangement, technique and more scientific rational multiple coil formula continuous countercurrent leaching device economically, not only every grade of continuous reverse flow leaching process is under preference temperature condition, create and keep improving leaching rate in concentration difference, and the leachate of every grade of inter-stage reaches completely separated as much as possible with medicinal material, the height that obtains high-quality active ingredient in energy-saving and cost-reducing leaches yield.
The purpose of this utility model is to reach by following measure, comprise that one end has loader and liquid outlet, the other end has the trough of slag-discharging device and inlet formation, the conveyor screw on the axle that connects driving mechanism with porous helical blade is set in trough, trough outside has heating jacket and/or ultrasonic wave member, particularly, several sections of trough parallel shapes are set up in parallel, between trough, mass transport end and material input are held concurrently extruder by taking over and supplying by being the skewed helical feed with conical shell, discharge gate is connected, make several sections of troughs form the roundabout connection of parallel shape head and the tail, and, between several sections of troughs, by the liquid-transport pipe-line with the high position gravity flow of liquid level difference, be communicated with, be integrally formed the multiple coil formula continuous countercurrent leaching device of interlock.
Deficiency for stepless Separation of Solid and Liquid in prior art or the aspect such as inter-stage Separation of Solid and Liquid is not thorough, adopt after structure of the present utility model, because trough outside is provided with heating jacket and/or ultrasonic wave member, at cavitation effect, under fuel factor effect, crude drug cell wall breaks fast, cause solvent and accelerate the active ingredient in infiltration and dissolved cell, continuous reverse flow leaching process is constantly being created and is being kept under the advantages such as Cmax is poor, increased the mass transfer force leaching, Dynamic Leaching makes diffusion boundary layer thin and upgrade fast, thereby leaching resistance to mass tranfer reduces, thereby improved leaching rate, again due to mass transport end between several sections of troughs and material input by the helical feed that is the skewed conical shell with extruded member hold concurrently extruder by take over and supply, discharge gate is communicated with, between several sections of troughs, be provided with the leachate liquid-transport pipe-line of the high position gravity flow of liquid level difference, so just make this one-level leachate being extruded reflux this one-level trough from being skewed cone housing, like this, the material active ingredient that this one-level leaches is also left in the leachate of this one-level.At different levels like this successively, make the leachate of every grade completely separated as much as possible with medicinal material, only allow the immersed material of appearing enter next stage, the leachate of next stage flow into upper level, namely allows less the material active ingredient having leached flow into next stage as far as possible.Like this, what just can make first one-level outflow is that active ingredient obtains the leachate fully leaching, and what last one-level was discharged is to contain hardly the material slag of active ingredient.If every one-level is only calculated by 70% leaching yield, second level yield can reach 91% so, and the third level can reach 97.3%, increases progression, and yield is higher.Compared to prior art, there is significant beneficial effect.
