French scientist Franzritter you Soxhlet invent and extracted lipid from milk using soxhlet extraction pipe
Close object.Hereafter soxhlet's extractor is just widely used in analytical chemistry, organic chemistry, life science, the science such as biolipid separation
Field.
With the utilization of soxhlet's extractor, there is development at full speed in especially analysis purification field in chemical field, for
Separate apparatus also revolutionary meaning, after rope extractor invention in 100 present years, soxhlet extraction pipe is
Through the laboratory apparatus as each chemical laboratory indispensability.
Soxhlet extraction pipe is mainly made of three parts.The extraction flask for holding extract liquor, holds the extraction of substance to be extracted
Pipe, the condenser pipe composition for alloing extract liquor to flow back.This three parts connects from bottom to top when use, to check interface upon connection
The leakproofness at place, leakproofness is intact to be can be used.Common ancillary equipment has the iron stand of retainer instrument and makes extraction when use
The heating device of agent boiling.
When using soxhlet extraction device, first heating device is placed in iron stand fixed extraction flask and extraction flask
In, low-temperature heat can use water-bath, high-temperature heating that can use electrothermal furnace.Then substance to be extracted is positioned in extracting tube, and handle
Extracting tube is positioned on extraction flask and is fixed on iron stand with iron clamp.Condenser pipe is placed on extracting tube again and uses iron clamp
It is fixed on iron stand, connects condensate pipe device and just connect completion, open condensed water and heating device starts extraction process.
Soxhlet extraction makes extractant recycle in the device using reflux and the principle of siphon, can reach and back and forth extract
Effect, not only can greatly extend extraction time can also save extraction medicament, and object to be extracted is extracted to the maximum extent,
It is big to overcome biography extracting process Chinese medicine usage amount, the low disadvantage of efficiency.
Soxhlet extraction device has very high status in extracting instrument, has a lot of other equipment cannot replace excellent
Point, but soxhlet extraction device also will appear some problems in practical operation：（1）Extracting substance cannot wrap up too sternly, mend
When adding extractant, extractant falls on that flow velocity on extract is too fast to be easy to substance to take extractant to.（2）Because extraction area is too small
Problem of non-uniform is extracted caused by and, if material, which is unevenly distributed, easily causes experimental error.（3）It is very few to extract material,
Caused by the too short problem of extraction time.
Invention content
The purpose of this utility model is to provide a kind of soxhlet's extractors improving extraction precision, mainly solve conventional rope
The problems such as solvent is easy to take material and low effect of extracting precision out of in family name's extraction equipment, the utility model mainly uses one kind
New liquid-dividing head form reduces the probability that extractant takes material out of, improves the precision of extraction, extraction efficiency is made greatly to carry
It is high.
The utility model improves the soxhlet's extractor of extraction precision, including condenser pipe, liquid separation column, liquid-dividing head, water dropper, extraction
Pipe, extraction flask, connecting tube, siphon pipe；
The lower end of the condenser pipe is connected to extracting tube, and extracting tube is the narrow cylinder in the wide lower part in top, under extracting tube
End is connected to extraction flask, and spherical inner tube is set in condenser pipe, and bottom of inner tube is stretched into extracting tube and connect with liquid separation column, liquid separation column
Liquid-dividing head is installed in bottom, and liquid-dividing head bottom is equipped with more than one water dropper, and the connecting tube and siphon pipe are mounted on extracting tube
The both ends of the same side, connecting tube are connected to the upper and lower part of extracting tube respectively, and connecting tube is set on the outside of siphon pipe, wrap up siphon
Pipe, siphon pipe one end are connected to extracting tube lower part side, and the other end passes through extraction bottom of the tube and stretches into extraction after being folded upward at burns
In bottle.
The siphon pipe is inverted U shape.
The diameter that the siphon pipe bends up place's pipe on extracting tube top upwards is less than siphon pipe other diameters everywhere, enhances rainbow
Suction phenomenon.
The condenser pipe is that ground is connected to extracting tube, extracting tube and the connectivity part of extraction flask.
The application method of the utility model is as follows：
（1）Extraction flask is fixed on iron stand, extraction drag is placed on the heating, takes 50mL's or so
Extractant, when extractant is easy volatile solvent, is clogged with plug above extraction flask in extracting in flask；
（2）Substance to be extracted is ground, 1g substances to be extracted is weighed and is placed on filter paper, make filter paper can filter paper edge fold
To be placed into extracting tube, it is placed in extraction bottom of the tube, then extracting tube is placed on extraction flask and is connected to extraction flask, and
It is fixed on iron stand with iron clamp；
（3）Condenser pipe is placed in above extracting tube and is connected to extracting tube, is fixed on iron stand with iron clamp, connects condensation
Water starts simultaneously at heating, and the temperature that the temperature of heating device is adjusted to be pre-designed is extracted.
Compared with prior art, the beneficial effects of the utility model are：
（1）The utility model can equipped with liquid separation column, liquid-dividing head and more than one water dropper in the bottom of the inner tube of condenser pipe
So that single-point extraction is promoted to multiple spot extraction, extraction efficiency is improved.
（2）The siphon pipe of the utility model extracting tube side is on the inside of connecting tube, the connecting tube in outside can protect compared with
Thin siphon pipe, prevents collision cleft.
（3）The siphon pipe of the utility model extracting tube top upwards bend up place pipe diameter be less than siphon pipe other everywhere
Diameter enhances siphonage.
