Description
Technical field
The utility model is related to a kind of soxhlet type separator, specifically a kind of Soxhlet extractor belongs to extraction separation
Engineering device technique field.
Background technology
Soxhlet type apparatus is a kind of common experimental device of the extraction and assay of compound, and operating process is basic
For：By sample in being wrapped in strainer or filter paper etc., it is put into extracting barrel；Solvent is added into flask, then to evaporative flask
Heating, the steam that solvent is formed enters extracting barrel along steam lead or condenser pipe is condensed, and flow in extracting barrel and dissolves sample
Soluble matter in product, when in extracting barrel solvent liquid level higher than in siphon pipe highest point along when occur siphon, what solvent took dissolving can
Molten object is back to flask together, and the solvent for being back to flask continues to be evaporated, and so recycles, until the soluble matter in sample is molten
Solution is complete.Relatively traditional leach extraction method, soxhlet type have the characteristics that more efficient, solvent dosage is few.Patent document
CN206463526U, CN206252880U, CN105158383A, CN202961958U etc. have carried out difference to soxhlet type apparatus
Transformation, assign new function.But it for the modified plastic material filled with superfine powder, is taken out because siphon pipe inlet is located at
A bottom is carried, remaining powder flows back into flask together after being dissolved sample substrates, it is difficult to by base material separation or efficiency
It is relatively low.
Utility model content
The purpose of this utility model is to provide a kind of soxhlet type dress for the separative efficiency that packing material and base material can be improved
It sets.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is：
A kind of Soxhlet extractor, including the condenser pipe, extracting barrel, flask and the heating device that are sequentially connected, the condenser pipe
It is connect with extracting barrel, the extracting barrel is connect with flask, and the heating device heats for flask, is set on the stack shell of the extracting barrel
It is equipped with solvent vapo(u)r conduit and siphon pipe, the water inlet of the condenser pipe is located at pipe shaft lower end, and water outlet is located at pipe shaft upper end, institute
The inlet for stating siphon pipe is located at 1/3~2/3 height of stack shell side.This highly desirable misgivings separative efficiency, accuracy and
The disturbance that the drop of cooling solvent precipitates powder when dripping.If height is too low, relative separation efficiency can be high, but drop is disturbed
Powder can be taken to flask when dynamic and solvent refluxing and influence accuracy.If height is too high, the solvent to flow back every time is less, point
It will be substantially reduced from efficiency.
Preferably, the inlet of the siphon pipe is located at 1/2 height of stack shell side.
Angle at the siphon pipe inlet between inlet tube and extracting barrel is less than 90 °, at the siphon pipe inlet
Angle between inlet tube and extracting barrel is preferably 30 °~60 °.The purpose of angle be manufacture convenience and separation it is accurate
Property.If angle is big, such as larger than 90 degree, when precipitating disturbed, it is possible to have a small amount of powder and enter siphon pipe and can not sink
Return in shallow lake.
The siphon pipe highest point goes out the height of vapour (liquid) mouth (lower end position) less than solvent vapo(u)r conduit.If siphon pipe
Higher than the height of steam lead, the liquid flux of highest point will be back to flask from steam lead, and the reflux of siphon pipe is made
With just without.
The utility model is simple in structure, easy to use, the siphon arrangement of use, improves the separation of packing material and base material
Efficiency, previous siphon pipe inlet can not be detached at all in least significant end because powder precipitation and material be dissolved into it is broken
Bits can be flowed into the solvent of reflux in flask.By improving siphon pipe inlet, powder precipitation and clast can be prevented
It is brought into flask.After soluble fraction is completely dissolved, reflux every time can reduce the concentration of soluble matter primary, to reduce
50% calculates, and is detached by 10 reflux, so that it may the concentration of soluble matter is reduced by 99.9% or more, fully meet general analysis
Requirement, better sample can be provided for material composition analysis.
Description of the drawings
Fig. 1 is Soxhlet extractor structural schematic diagram commonly used in the prior art.
Fig. 2 is the utility model extracting barrel structural schematic diagram.
Specific implementation mode
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, 2, a kind of Soxhlet extractor, including be sequentially connected condenser pipe 1, extracting barrel 2, flask 3 and heating
Device 4, the condenser pipe 1 are connect with extracting barrel 2, and the extracting barrel 2 is connect with flask 3, and the heating device 4 adds for flask 3
The water inlet of heat, the condenser pipe 1 is located at pipe shaft lower end, and water outlet is located at pipe shaft upper end, as shown in Fig. 2, the extracting barrel 2
Solvent vapo(u)r conduit 5 and siphon pipe 6 are provided on stack shell.
As shown in Fig. 2, the inlet of the siphon pipe 6 is located at 1/3~2/3 height of stack shell side, it is preferable that the rainbow
The inlet of suction pipe 6 is located at 1/2 height of stack shell side.
Angle (angle α as shown in Figure 2) at 6 inlet of the siphon pipe between inlet tube and extracting barrel is less than 90 °,
Preferably 30 °~60 ° of angle.
Height of the siphon pipe liquid outlet highest point less than the lower end position of solvent vapo(u)r conduit venthole.
When in use, first flask is installed, suitable solvent is then added；Then sample is put into extracting barrel, and will
Extracting barrel is mounted on flask and fixes, and finally installation connects the condenser pipe of water pipe.After installation is complete, cooling water is connected, is opened
Heating power supply, the solvent vapo(u)r that solvent is formed under the action of heat enter extracting barrel and cooling liquid by solvent vapo(u)r conduit,
Gradually soluble matter in sample is dissolved.When the height of the liquid phase solvent in extracting barrel is more than siphon pipe maximum height, siphon pipe
Solvent more than inlet will be back to flask, so recycle, until terminating.
Above-described embodiment does not limit the utility model in any way, every by the way of equivalent substitution or equivalent transformation
The technical solution of acquisition is all fallen in the scope of protection of the utility model.
