Description
Technical field
The present invention relates to chemical analysis pre-treatment experimental provision technical field, more particularly, to a kind of for solid-liquid extraction
Device.
Background technology
Solid-liquid extraction is to be dissolved the soluble component in solid sample using organic or inorganic solvent, makes it into liquid
Phase, then the operating process that insoluble solid and liquid are separated.With the raising of industrial expansion and living standards of the people, solid-liquid
It is extracted in daily life and the application in industry is more and more extensive.
Solid-liquid extraction mainly has the technologies such as decocting method, extraction, the way of distillation, circumfluence method and soxhlet extraction.Wherein, decoct
Method is simple and easy to do, but impurity is more in extract solution, is unfavorable for the purification ＆ isolation of object；Extraction is applied to active ingredient heat
Destructible and the extraction containing much starch, natural gum, pectin, mucilaginous natural plants, but method extraction time length, extraction effect
Rate is not high；The way of distillation can extract the stronger material of separating volatile with the different material of separating volatile；Circumfluence method is extracted
Efficiency is high compared with cold-maceration, but the composition of heated destructible should not use this method, and solvent-oil ratio is big, troublesome in poeration；Surname extraction
Method is a kind of dynamic continuous circumfluence extraction technology, and easy to operate, solvent load is few compared with common circumfluence method, and extraction efficiency is then obvious
Higher than common backflow, but the material of heat endurance difference and high volatility it is not suitable for extracting.It can be seen that five kinds of extractive techniques respectively have spy
Point, wherein, soxhlet extraction apparently higher than the extraction efficiency of other four kinds of methods, the way of distillation can separate different volatility
The advantages of component, is favored by chemical analysis worker.
As it was previously stated, the way of distillation and soxhlet extraction are the extractive techniques of two kinds of routines in analytical chemistry.Because Soxhlet carries
It is to be carried out circulation extraction by solvent obtained by thermal evaporation using extract solution to follow the example of, so being typically that to be used to extracting heat endurance good, no
Volatile composition；Distillation is the process for utilizing the volatile difference of each component and separating component, can realize that low boiling is easy
The extraction of volatile substance.It can be seen that two kinds of extracting methods are adapted to the material of extraction to be different.Under the conditions of current technology, such as
Fruit needs the material weak to the material of high volatility in same solid sample and volatility to extract, then needs to weigh two parts
Sample, and extraction is carried out to two parts of samples respectively and can be realized using distillation equipment and surname extraction equipment.Currently without same
Volatile in solid sample and not volatile components extraction technology is realized in one device.This kind of extracting mode not only operates numerous
It is trivial, and need to expend double or even more times, reagent, human and material resources, have a strong impact on detection operating efficiency.
The content of the invention
The purpose of the present invention is intended to overcome the shortcomings of the prior art, there is provided and a kind of simple to operate, extraction efficiency is high,
Save time and the low device for solid-liquid extraction of extraction cost.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of device for solid-liquid extraction, including apparatus,Soxhlet's；The apparatus,Soxhlet's includes extraction flask, extraction tube, the
One condenser pipe and the siphon pipe and the first steam lead for being arranged at extraction tube both sides；At the inner tube lower end of first condenser pipe
It is provided with the 3rd valve；The first steam lead lower end is provided with the second valve；Bottom in the extraction tube, which is set, to be had
The dividing plate of through hole, extraction tube is divided into upper and lower two cavitys communicated；The height of the dividing plate is less than the top of siphon pipe；Institute
The cavity top for stating extraction tube is provided with the second connecting hole, and second connecting hole is connected with the second condensation by a connecting tube
Pipe；The 4th valve is provided with the connecting tube；The lower cavity of the extraction tube is provided with the first connecting hole, and described first connects
Hole is connect to connect with the top of extraction flask by one second steam lead；The first valve is provided with second steam lead.
Preferably, first condenser pipe uses spherical condensation tube.
Preferably, second condenser pipe uses serpentine condenser.
Preferably, first valve, the second valve, the 3rd valve and the 4th valve are switched using cock.
Preferably, the extraction flask is tightly connected with extraction tube by grinding port plug.
Preferably, the extraction tube is connected with the first condenser pipe by ground adapter.
Preferably, the connecting tube is connected with the second condenser pipe by ground adapter.
Compared with prior art, the invention has the advantages that：
The present invention realizes extraction respectively volatile in solid sample in same device and not volatile components, significantly reduces
Extractant dosage and sample consumption；Due to two parts of samples need not be weighed, it is not required that extraction is easy respectively on two complete equipments
Volatilization and not volatile composition, greatly save human and material resources and test period；And it is simple to operate, only it need to pass through control
Volatile and not volatile substances extraction respectively in same device can be achieved in several valves, effectively increases operating efficiency.
