Abstract

The utility model relates to a traditional Chinese medicine countercurrent continuous leaching machine which is composed by a solvent inlet, a dilute liquid gruff outlet, a leaching groove, a heating plate, an agitator, a settlement groove, a gruff turning bucket, a drug inlet and a leaching liquid outlet. The heating plate separates the thin shell long groove into a plurality of leaching grooves, the settlement groove communicates the adjacent two leaching grooves, a plurality of settlement grooves combine the all leaching grooves into a tandem countercurrent continuous leaching machine, the partial drug which is difficult to settle and be separated can flow and transform into the adjacent leaching groove through the gruff turning bucket counter leaching liquid, therefore implementing multilevel countercurrent continuous leaching can greatly reduce the radio between the solvent and the drug, improve the equipment volume efficiency and active ingredient recycling rate and greatly reduce the energy consumption of post treatment of the evaporating and concentrating device.

Description

The continuous leaching machine of Chinese medicine adverse current

Technical field:

This utility model relates to the continuous leaching machine of a kind of Chinese medicine adverse current, belongs to chemical industry abstraction technique field, is applicable to that with all kinds of solvents Chinese crude drug, Folium Camelliae sinensis and plant pigment etc. being carried out adverse current leaches continuously.

Background technology:

Present most of Chinese medicine leaches and adopts single pot of batch (-type) leaching method, no matter has adopted compulsory measures such as heating or stirring in the leaching process, all is helpless to break the concentration diffusive equilibrium rule between medical material and the leachate, in case the leaching effect just stops after reaching balance.For disequilibrating, have only and discharge leachate time adding fresh solvent again again and again in the production, repeatedly active ingredient is extremely rare in the leachate after the leaching, and repeatedly the mixed active ingredient concentration of leachate is well below the 1st leachate concentration.This single pot of leaching equipment efficient is low, and solvent load is many, increases the load and evaporation energy consumption of evaporation and concentration after-treatment device greatly.Existing number of patent application is 93237130.2 adverse current percolation batch extractor group equipment flowsheet complexity, and because of herbal mixture material thickness profile does not wait, spiral lamina perforate size difficulty satisfies the medical material grain through needs, and structure can't satisfy the cleaning requirement of GMP, the equipment manufacturing cost costliness.Number of patent application 99224644.7 and 99225587.2 multistage countercurrent continuous extraction machine structures are simple than adverse current percolation batch extractor group far away, but have the simple difference in specific gravity between extract and the extractant of leaning on, difficulty reaches the purpose that the complete settlement separate realization adverse current of liquid-solid phase leaches continuously.This is owing to the various medical material rerum natura poor morphology opposite sex in many herbal mixture materials are very big, wherein the air that receives in the part medical material is difficult in the short time and drives away, so just swimming in the leachate can't sedimentation, has a strong impact on this simple settlement separate mechanism by difference in specific gravity and realizes the operation requirement that adverse current leaches continuously.

Summary of the invention:

The purpose of this utility model is to overcome the shortcoming that above-mentioned each patented technology exists, provide a kind of Chinese medicine adverse current continuous leaching machine, it had both utilized sedimentation method for separating to realize that liquid-solid adverse current leaches continuously, adopt mandatory mechanical assistance measure again, make the reverse handover of part floatability Chinese crude drug, make in the leaching various Chinese crude drugs all can carry out adverse current and leach continuously.

The technical solution of the utility model is: it comprise residue filtrate return port, solvent inlet, the outlet of thin liquid residue, vortex groove, leaching tanks, tiltedly subsider, agitator, turn over slag bucket, slag bucket shaft gear, tooth bar, slag bucket axle, the turnover of hot plate thermal source pipe, screen pack, leachate dashpot, screen pack slot, leachate outlet, hydraulic unit driver, hollow hot plate, subsider end opening, pneumostome, subsider is suitable for reading and the medical material import is formed; Be characterized in: A, will have the shell elongated slot of top cover to be separated into a plurality of identical leaching tanks with hollow hot plate, agitator is established at each leaching tanks center, one of them agitator is driven by driving machine, and all the other agitators drive one by belt pulley according to next by the agitator that driving machine drives; B, establish an oblique subsider between adjacent two leaching tanks, suitable for reading and two leaching tanks of end opening UNICOM of subsider, by a plurality of subsiders whole leaching tanks are together in series, the leachate flow velocity that control makes progress from the subsider end opening does not influence from the downward sedimentation of the subsider Chinese crude drug that enters suitable for reading, medical material and leachate in the placed in-line leaching are in the reverse serial movement, medical material is in the concentration unbalanced state all the time with the leachate that contacts, diffusion also can constantly be carried out between the liquid-solid phase, leaching progression (leaching tanks number) should just determine according to leaching the difficulty or ease and the effective ingredient response rate, cooperate to force to stir and heat and further promote diffusion, promoting the mobile power of leachate is solvent inlet end liquid level difference, promotes medical material and upwards enters the lifting force that subsider power suitable for reading is the agitator generation; Establish a venetian blind type between C, two the adjacent leaching tanks and turn over slag bucket, utilize and turn over slag bucket and will swim in the contrary leachate of Chinese crude drug on the liquid level and flow to and shift; D, after the leaching tanks of medical material import department, be equipped with one and leach dashpot, between leaching tanks and leachate dashpot, be equipped with the polylith screen pack, dense leachate enters the leachate dashpot through the polylith screen pack, and piece of visual screen pack stopping state is extracted out in proper order; E, establish the vortex groove of an easy eddy generation in the leaching tanks of solvent inlet end, utilize the eddy current effect that its produces will be buoyant and can be sent to the medicinal residues filtration system with the pump extraction in the lump by settled medicinal residues, the residue filtrate that leaches still returns the residue filtrate return port.

The continuous leaching machine compact conformation of Chinese medicine adverse current, leach progression and be no less than secondary, surpass and do not limit more than the secondary, volume of equipment efficiency far height has the multi-functional infuser of batch (-type), and solvent is little with the ratio of medical material, and the 1st leachate concentration during single pot of leaching of leachate concentration ratio is taller, yield of effective components height in the medical material, extraction temperature leaches all to boiling from room temperature and adapts to, and device structure has taken into full account the GMP code requirement, is the ideal equipment that substitutes the single pot of batch (-type) Chinese medicine leaching equipment that falls behind.
