Description
Technical field
The present invention relates to the recovery technology such as steam, waste gas field, and in particular to a kind of solvent reclaimer.
Background technology
In organic chemistry filed, all kinds of solutes of HMW often are dissolved with the organic solvent of low molecule amount to carry out
Prepare, pre-treatment or the post-processing step such as purification, and after preceding processing or post processing, often need solvent from solute
In remove and reclaimed, prevent solvent volatilization from influenceing environment etc..Because most solvent is all that low molecular weight organic closes
Thing, therefore there is preferable volatile performance, therefore at present during recycling design, often cause by way of heating
Substantial amounts of solvent forms steam and carries out volatilization so as to which it be separated with solute, and recycling design.
Can be using nitrocotton as raw material, in preparation process, in order to which solvent is separated during single-base powder is prepared
And reclaimed, prior art is usually heating response material, and is extracted out solvent vapo(u)r using exhaust column, but in single-base powder
Always there is partial digested cotton dust to enter in exhaust column before and after shaping；Particularly when small size medicine is made, because air quantity is big, or
Equipment lacks management, can all aspirate part powder into exhaust column.These adsorbing powder dusts are in exhausting inside pipe wall, year in year out,
Exhaust column is easily blocked, influences the normal recovery of solvent.
The content of the invention
It is an object of the invention to provide a kind of solvent reclaimer, can carry out dedusting to exhaust column.
To reach above-mentioned purpose, base case of the invention is as follows：Solvent reclaimer, including retort and to retort
The heater of heating, in addition to dust removing units and recovery unit；Dust removing units include dust absorption fan, exhaust column, motor, rotating shaft and
Gear；Exhaust column one end connects with retort, and the exhaust column other end connects with dust absorption fan；The output shaft of motor connects with rotating shaft
Connect, rotating shaft side is provided with the hairbrush for brush exhausting inside pipe wall, and rotating shaft opposite side is provided with supporting plate, and supporting plate connects with pinion rotation
Connect；Exhausting inside pipe wall is provided with the ring gear engaged with gear, and gear is provided with the roller bearing for being used for cleaning exhausting inside pipe wall；Recovery
Unit includes condenser pipe and the recovery tube connected with exhaust column, and recovery tube is provided with check valve, for collecting going out for liquid solvent
Liquid mouth is located on the outer wall of recovery tube with the converting interface for connecting vacuum plant, condenser pipe.
The operation principle of above-mentioned technical proposal is：
When recycling design, converting interface is connected into vacuum plant, heater is worked, allow solvent under conditions of low pressure
Evaporation；Check valve is opened, recovery tube can be entered by exhaust column after solvent evaporation, and it is by condenser pipe that gaseous solvent is cold
Coagulate for liquid, then collect liquid solvent from liquid outlet, when liquid outlet does not have solvent outflow, close heater, treat
After retort is cooled to normal temperature, vacuum plant is disassembled, that is, reaches the purpose of recycling design.
When dedusting, check valve is closed, starts motor and dust absorption fan；The output shaft of motor drives axis of rotation, makes
The hairbrush brush exhausting inside pipe wall being connected with rotating shaft is obtained, so that the dust on exhausting inside pipe wall departs from exhausting inside pipe wall；Meanwhile turn
Axle, which rotates, drives supporting plate to rotate, and supporting plate is carried out on the ring gear of exhausting inside pipe wall centered on surrounding rotating shaft with moving gear again
Rotate, the roller bearing on such gear carries out secondary cleaning to the exhausting inside pipe wall after hairbrush brush；Taken off from exhausting inside pipe wall
The dust fallen is discharged exhaust column under the sucking action of dust absorption fan；Then motor and dust absorption fan are turned off, that is, is reached
To the effect to exhaust column dedusting.
With in the prior art can not to exhaust column carry out dedusting solvent reclaimer compared with, above-mentioned technical proposal it is beneficial
Effect is：
1st, by the first cleaning of hairbrush, allow the dust of exhausting inside pipe wall can be in hairbrush and the friction masterpiece of exhausting inside pipe wall
Easily just come off under, so as to first remove most dust on exhausting inside pipe wall, at the same time, because dust absorption fan carries
The negative pressure of confession, the dust after coming off can be soon sucked out, so as to reach the purpose of rough dusting.
2nd, simultaneously, rotating shaft allow supporting plate rotate during so that gear can be carried out on the ring gear of exhausting inside pipe wall
Circumferential rotation, i.e. gear is not only revolved round the sun centered on rotating shaft, but also can carry out rotation, and so drive roller bearing also can be
Rotation and revolution are carried out on exhausting inside pipe wall, the purpose of secondary cleaning, and roller bearing and exhausting are not only reached to exhausting inside pipe wall
Rolling friction is produced between inside pipe wall, to the secondary cleaning effect of exhausting inside pipe wall more preferably.
3rd, the technical program is when recycling design, using being recovered under reduced pressure, can not only allow heater heating-up temperature not
Even if being volatilized with too high solvent, security incident caused by high temperature etc. is avoided, and the solvent temperature of steam condition will not be too high,
When condensation on recovery tube, it is easier to liquid is condensed into, it is higher to the rate of recovery of solvent.
4th, the solvent vapo(u)r in the technical program first passes through exhaust column and entered back into recovery tube by reclaiming on tube wall
Condenser pipe is condensed, and condensation effect is more preferably.
5th, the hairbrush in the technical program can also play a certain degree of suction-operated to dust, be more conducive to allow dust to protect
Stay in exhaust column.
Preferred scheme one, based on scheme preferred scheme, recovery tube is vertically located at the exhaust column away from retort
One end.Vertical design is returned it is possible to prevente effectively from dust enters recovery tube, and make it that dust is retained in exhaust column as far as possible
It is more preferable to receive obtained solvent purity.
Preferred scheme two, based on scheme preferred scheme, is provided with the suction vertical with solvent water conservancy diversion direction in recovery tube
Water layer.The moisture absorption that water accepting layer will can be mingled with solvent, solvent quality is more preferable, and water accepting layer and solvent water conservancy diversion direction are hung down
Directly, water removal effect is more preferable.
Preferred scheme three, based on scheme, preferred scheme one or preferred scheme two preferred scheme, exhaust column is close
One end of retort is removably connected with dust suction piece.The dust absorbing that dust suction piece will preliminarily can be run out of from retort, from
And reduce the frequency that dedusting is carried out by motor, dust absorption fan, that is, reduce cost of equipment maintenance.
The preferred scheme of preferred scheme four, preferably three, heater are electric heating cover, and the retort is embedded
In heater.Electric heating cover can easily control temperature, so that this equipment can be easily applied to different boiling
Solvent recovery, it is simple to operate.
The preferred scheme of preferred scheme five, preferably three, condenser pipe are coiled pipe.The contact surface of coiled pipe and recovery tube
Product is bigger, and condensation effect is more preferably.
