Abstract
Solvent recovery unit in preserving kettle's plant residue, residue fumigation tube is housed bottom preserving kettle, boiling steam outlet pipe is provided with threeway, connect return valve in threeway one end, return valve connects condenser, is connected with fractionation valve at the other end of threeway, fractionation valve is connected to the bottom of a fractionating column, fractionation column base is equipped with drainpipe, and the recovery tube of low concentration leaching liquor, the recovery tube of middle concentration leaching liquor and the recovery tube of high concentration leaching liquor are equipped with in side, and top is equipped with air and is gone out pipe.Owing to installing residue fumigation tube bottom preserving kettle, the boiling steam outlet pipe at top installs threeway, one end of threeway connects fractionating column, when infusion terminates, the first extract in preserving kettle passes into the bottom of water vapour from preserving kettle after releasing, raw material residue in preserving kettle is fumigated, leaching liquor solvent in residue is taken out of by the steam steamed, and steam enters in fractionating column after fractionation valve, the leaching liquor fractionation in steam is reclaimed with fractionating column.
Description
Technical field
The utility model belongs to effective ingredients in plant extraction equipment technical field, relates to solvent recovery unit in a kind of preserving kettle plant residue.
Background technology
When the extracts active ingredients of plant, plant material is after solvent soaking, infusion, obtain the first extract containing effective ingredients in plant, after first extract is admitted in concentration tank and carries out concentrated processing, the raw material residue containing extraction solvent remaining in preserving kettle, raw material residue is worked as discarded object from the slag-drip opening of preserving kettle and is discharged.Because a lot of plant adopts edible alcohol etc. to be worth higher solvent as leaching liquor, in the raw material residue of discharging, there is part leaching liquor to permeate wherein, be discharged when discharging with residue, cause the loss of leaching liquor.
Summary of the invention
For in effective ingredients in plant leaching process, part leaching liquor is discharged with raw material residue, cause the problem that leaching liquor loses, the utility model provides solvent recovery unit in a kind of preserving kettle plant residue, at preserving kettle's lower inside, steam-heating pipe and dam plate are installed, side is provided with slag-drip opening, bottom is provided with just extract and goes out pipe, top is provided with leaching liquor and enters pipe and feed(raw material)inlet, the boiling steam outlet pipe of leaching liquor is housed at preserving kettle top, boiling steam outlet pipe is in series with two condensers, the return duct of condenser connects the middle and upper part of preserving kettle, residue fumigation tube is housed bottom preserving kettle, boiling steam outlet pipe is provided with threeway, return valve is connect in threeway one end, return valve connects condenser, fractionation valve is connected with at the other end of threeway, fractionation valve is connected to the bottom of a fractionating column, fractionation column base is equipped with drainpipe, the recovery tube of low concentration leaching liquor is equipped with in side, the recovery tube of middle concentration leaching liquor and the recovery tube top of high concentration leaching liquor are equipped with air and are gone out pipe.
Adopt technique scheme, owing to installing condenser and return duct above preserving kettle, after leaching liquor boiling, boiling gas is back in preserving kettle after condensation, realizes the closed circulation infusion of raw material, guarantees that leaching liquor does not arrange loss in boiling process China and foreign countries; Owing to installing residue fumigation tube bottom preserving kettle, the boiling steam outlet pipe at top installs threeway, one end of threeway connects fractionating column, when infusion terminates, after first extract in preserving kettle is released, pass into the bottom of water vapour from preserving kettle, raw material residue in preserving kettle is fumigated, leaching liquor solvent in residue is taken out of by the steam steamed, steam enters in fractionating column after fractionation valve, with fractionating column, the leaching liquor fractionation in steam is reclaimed, the loss of leaching liquor in residue can be reduced like this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment: as shown in Figure 1, solvent recovery unit in a kind of preserving kettle plant residue, at preserving kettle 4 lower inside, steam-heating pipe 2 and dam plate 1 are installed, side is provided with slag-drip opening 12, bottom is provided with just extract and goes out pipe 13, top is provided with leaching liquor and enters pipe 3 and feed(raw material)inlet 5, the boiling steam outlet pipe 6 of leaching liquor is housed at preserving kettle top, boiling steam outlet pipe 6 is in series with two condensers 8, the return duct 11 of condenser connects the middle and upper part of preserving kettle 4, residue fumigation tube 14 is housed bottom preserving kettle 4, boiling steam outlet pipe 6 is provided with threeway 9, return valve 7 is connect in threeway 9 one end, return valve 7 connects condenser 8, fractionation valve 10 is connected with at the other end of threeway, fractionation valve 10 is connected to the bottom of a fractionating column 19, drainpipe 15 is housed bottom fractionating column 19, the recovery tube 16 of low concentration leaching liquor is equipped with in side, the recovery tube 17 of middle concentration leaching liquor and the recovery tube 18 of high concentration leaching liquor, top is equipped with air and is gone out pipe 20.
