The purpose of this utility model is to provide a kind of Soxhlet extractor, and remaining residue will not drain to extraction after having extraction
Pipe blocks siphon pipe, facilitates the clean effect of extraction tube.
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of Soxhlet extractor, including condenser pipe, extraction tube, extraction flask, the lower end of the condenser pipe and extraction tube it is upper
End connection, the extraction tube are plugged in one inside the upper port outer rim of the inside of protective cover and extraction tube and the port of protective cover
Molding setting, the lower end of the protective cover is gradually reduced to be connected to the upper end of extraction flask；Through-hole (5) is provided on the extraction tube
And siphon pipe, characterized in that the lower end of the condenser pipe extends downwardly the extraction for being detachably connected and being useful for placing object to be extracted
Bag.
By using above-mentioned technical proposal, object to be extracted is placed by the way that bag for extracting is arranged, more traditional uses fat-free filter paper
For band extract, it can prevent the residue of object to be extracted in extraction process from overflowing pollution extraction tube or block siphon pipe；Just
In the cleaning of later stage extraction tube.
The utility model is further arranged to：Up turnup forms a circle crimping for the lower end of the condenser pipe, described to carry
Bag taking is set on crimping and the bag for extracting is by being arranged the cinch cord tightening pocket opening in port, makes bag for extracting port and crimping
Close connection.
By using above-mentioned technical proposal, bag for extracting is connected by the crimping of cinch cord and condenser pipe, is connected firmly, can prevent
Only bag for extracting falls off in extraction process；Meanwhile it extracting and completing bag for extracting easy to disassemble later.
The utility model is further arranged to：The lower end of the condenser pipe be equipped with hook, the bag for extracting port it is interior
Diameter is less than condenser pipe lower end outer diameter and has retractility, and the port lower part of the extraction band is provided with hanging hole corresponding with hook.
By using above-mentioned technical proposal, the port inner diameter of bag for extracting is less than the outer diameter of condenser pipe lower end and with flexible
Property, bag for extracting port can be made to be fitted closely with condenser pipe lower end；Keep bag for extracting reliably solid by the cooperation of hook and hanging hole again
It is scheduled on condenser pipe lower end.
The utility model is further arranged to：The extraction flask is round-bottomed flask or boiling flask.
The utility model is further arranged to：The bag for extracting material be cotton fiber, zein fiber, Europe root yarn, gauze,
The one of which of PP non-woven fabrics or a variety of combinations.
In conclusion the utility model has the advantages that：
First, object to be extracted is placed on by bag for extracting in extraction tube, it can prevent the residue to be extracted in extraction process from overflowing
Go out into extraction tube or block siphon pipe, is convenient for the cleaning of later stage extraction tube；
Secondly, bag for extracting and condenser pipe be detachably connected, bag for extracting can be removed and be cleaned after the completion of experiment.
