Reduce the breakage rate of extraction flask.Siphon hose section 52 is detachably connected with inducer, outlet section by siphon joint 51, works as needs
During adjustment siphon liquid level, the siphon hose of different length need to be only changed, easy to use.
As a example by determining the fat content in fish flour using Soxhlet extraction device of the present utility model, during extraction, by fish flour
Sample bag is placed in filter cylinder 6, then filter cylinder 6 is put in extraction tube 2, adds petroleum ether in evaporative flask 1.
When this utility model is used, the first open and close valve 411 is closed, the second open and close valve 421 is opened, and carries out liquid in early stage
Circulation extraction, petroleum ether are heated generation steam, and spheroid is in floating state in vapor action, when steam flow increases, spherical
Body floats and blocks steam pipe 4, closes steam (vapor) outlet；Simultaneously because steam pressure rises, make petroleum ether directly along siphon
5 rise to filter cylinder 6 and soak material, and after 1 liquid level of evaporative flask drops to siphon below 5, steam rises to along siphon 5 and carries
Take pipe 2 and realize steam pressure release, when insufficient pressure is to support that spheroid blocks 4 mouthfuls of steam pipe, spheroid receives gravity fall
Steam passage is opened, spheroid is in floating state again by vapor action, at this moment petroleum ether can be flowed back in the case where siphon 5 is acted on rapidly
To evaporative flask 1, subsequent cycle is carried out, petroleum ether can constantly carry out rising reflux cycle, realize the Rapid Circulation of hot petroleum ether
Extraction；When the method for later stage routinely apparatus,Soxhlet'ses carries out steam condensation cycle and extracts, only need the second bypass duct 42 can be closed
Close, so as to tie point pipe 41 is opened.
Finally it should be noted that above example is only in order to illustrating the technical solution of the utility model, rather than to this reality
With the restriction of novel protected scope, although having made to explain to this utility model with reference to preferred embodiment, this area general
Logical it will be appreciated by the skilled person that can modify to the technical solution of the utility model or equivalent, without deviating from this
The spirit and scope of utility model technical scheme.
