Description
Technical field
The utility model is related to a kind of soxhlet's extractors improving extraction efficiency, belong to experimental instrument field.
Background technology
Soxhlet's extractor is a kind of common chemical apparatuses, is widely used in analytical chemistry, organic chemistry, life section
The scientific domains such as, biolipid separation.Soxhlet extraction makes extractant recycle in the device using the principle of reflux and siphon,
To achieve the effect that back and forth to extract, not only can greatly extend extraction time can also save extraction medicament, to the maximum extent
Object to be extracted extracts, and it is big to overcome conventional extraction process Chinese medicine usage amount, the low disadvantage of efficiency.But soxhlet extraction fills
It sets and also will appear some problems in practical operation：（1）Extracting substance cannot wrap up too sternly, when adding extractant, extractant
It drops onto in the too fast extractant for being easy to substance to be extracted to be brought into flask of flow velocity on extract；（2）Because extracting area
It is too small and caused by extract problem of non-uniform, if material, which is unevenly distributed, easily causes experimental error；（3）Extract material mistake
Less, the too short problem of extraction time caused by.
Utility model content
In view of the above-mentioned problems, the utility model provide it is a kind of improve extraction efficiency soxhlet's extractor, including condenser pipe 1,
Extracting tube 5 and flask 10, three components are sequentially connected from top to bottom, and junction is ground glass joint, to ensure device
Air-tightness；
It is equipped with spiral condensate pipe 2 in condenser pipe 1, the water inlet 3 and water outlet 4 of spiral condensate pipe 2 are respectively placed in cold
The both sides tube wall of solidifying pipe 1, water outlet 4 are higher than water inlet 3；
5 tube wall of extracting tube is equipped with gas-guide tube 6 and siphon pipe 7；It is equipped with material ware 8 in extracting tube 5, is provided on material ware 8
Osculum is connected to siphon pipe 7, and ensure extraction agent stablizes reflux.
Preferably, the material of material ware 8 is polyethylene, and polyethylene is that high-quality plastics product is not substantially anti-with organic reagent
It answers, and there is certain flexibility, can prolong the service life and facilitate the placement and taking-up of material ware.
Preferably, absorbent cotton 9 is also placed in material ware 8, absorbent cotton bulkiness can fix material to a certain extent,
Certain extractant can also be adsorbed simultaneously, extend extraction time.The usability of absorbent cotton is disposably to be unable to Reusability.
The course of work：In use, extract liquor is added in flask 10, material to be extracted is put into material ware 8, then by material
Ware 8 is put into extracting tube 5；10 3 condenser pipe 1, extracting tube 5 and flask components are sequentially connected from top to bottom（Such as Fig. 1 institutes
Show）, heating device is placed below flask 10（Low temperature can heat in water-bath, and high temperature can be positioned in electric jacket,
Electrothermal furnace may be used to heat）, the water inlet 3 of spiral condensate pipe 2 is connect with water pipe, you can start to extract（According to reality
Needs are tested, can connect more set soxhlet's extractors, be carried out at the same time extraction, condensed water can be also connected in series with, and make full use of resource）；Extraction
After taking the heated boiling of liquid, steam is escaped by the gas-guide tube 6 of extracting tube 5 in condenser pipe 1, in the work of spiral condensate pipe 2
It with lower condensation liquefaction, instills in the material ware 8 in extracting tube, treats extraction material and extracted, the extract liquor after extraction is through extraction
The siphon pipe 7 of pipe 5 is taken to flow into flask, extract liquor participates in cycling extraction after heated boiling again.
The beneficial effects of the utility model：
1, material is positioned in material ware by the utility model, can prevent the extract liquor that material is dripped from bringing flask, object into
Absorbent cotton in material ware can also play the role of fixed and adsorb material, and material is allow more fully to be extracted；
2, to reduce consumption of the soxhlet extraction device to extractant to the greatest extent, the utility model uses spiral condensing unit, extraction
Take liquid steam can be simultaneously by the dual condensation effect of condensation water and air in condenser pipe, and spiral condensation increases condensation area
Condensation effect is improved, therefore spiral condensing unit has good effect particular for the volatile organic reagent of low boiling point, so as to
Suitably to increase the reaction efficiency for improving entirety to the heating temperature of extractant.

Specific implementation mode
Embodiment 1
As shown in Figure 1, a kind of soxhlet's extractor improving extraction efficiency, including condenser pipe 1, extracting tube 5 and flask 10, three
A component is sequentially connected from top to bottom, and junction is ground glass joint；Spiral condensate pipe 2, spiral are equipped in condenser pipe 1
The water inlet 3 and water outlet 4 of condensate pipe 2 are respectively placed in the both sides tube wall of condenser pipe 1, and water outlet 4 is higher than water inlet 3；Extraction
5 tube wall of pipe is equipped with gas-guide tube 6 and siphon pipe 7；It is equipped with material ware 8 in extracting tube 5, osculum and siphon pipe 7 are provided on material ware 8
Connection.
For extracting the organic matter in coal, for the extractant used for dichloromethane, dichloromethane is common extractant
Solubility property very by force can be very strong with the most of organic matters of solvent but its volatility and boiling point only has 40 DEG C, uses general condensation dress
Although setting with condensation effect but over time it can clearly be seen that the amount of dichloromethane is being reduced.Because of dichloromethane boiling point 40
DEG C so mode of heating takes heating water bath.It is as follows：
After coal sample is crushed, sample is sieved, -200 mesh part below is taken, weighs 1g and be placed on the absorbent cotton of material ware；
Take the extractant of 50mL or so in flask, flask is fixed on iron clamp on iron stand, and flask bottom end is placed in water-bath；It will claim
