Description
Technical field
The present invention relates to apparatus,Soxhlet's, be specifically related to the straight-through heat collecting type apparatus,Soxhlet's of a kind of inner tube.
Background technology
Soxhlet extraction is a kind of classical way of extract compounds from solid matter, and it is continuously extracted solid matter by solvent refluxing by neat solvent, has not only saved solvent but also improved extraction efficiency.Apparatus,Soxhlet's (claiming again fat extractor or Soxhlet's apparatus) is the agent set of realizing soxhlet extraction, traditional apparatus,Soxhlet's is comprised of solvent bottle, extraction tube, condenser pipe three parts, and extraction tube comprises siphon pipe, the tube connector of body and body both sides.First solid matter is ground before the extraction, be placed in the extraction tube body, the solvent bottle heating, the solvent gasification, steam passes into the extraction tube body from tube connector, splash into after the condensation in the extraction tube body, solid matter composition in the extraction tube body is extracted, when extraction tube body internal solvent liquid level surpassed siphonal highest point, the solvent that contains extract flowed in the extraction flask through siphon pipe, and the solvent that flows in the solvent bottle continues to be heated gasification, rise, condensation, splash in the extraction tube body, so circulation is repeatedly constantly extracted solid matter, and the material that extracts is enriched in the solvent bottle by solvent.Number be the utility model of CN 2011500467 such as Granted publication, designed a kind of double-layered sleeve heat collecting Soxhlet extractor that is incubated, the body of its extraction tube comprises outer tube, the upper grinding port of outer tube is connected with condenser pipe, the lower ground of outer tube is connected with solvent bottle, be arranged with inner tube in the outer tube, the top of inner tube has through hole to communicate with outer tube, and the bottom is equipped with the glass filter disc, and siphon pipe is connected with inner tube, during extraction, solid matter is placed in the inner tube, and steam rises from outer tube, splashes into after the condensation in the inner tube, the extraction solid matter, although the heat that utilizes like this solvent evaporation process to produce makes the inner tube extraction temperature higher, the outer tube heat radiation tube connector that compares is slow, both improve extraction efficiency, saved again energy consumption.But because steam gets on from outer tube, dispel the heat still very fast, temperature control is not easy, and extraction efficiency is still lower.
Summary of the invention
It is slow that technical problem to be solved by this invention provides a kind of heat radiation, and temperature control is easy, the straight-through heat collecting type apparatus,Soxhlet's of the inner tube that extraction efficiency is higher.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of inner tube leads directly to the heat collecting type apparatus,Soxhlet's, by solvent bottle, extraction tube, condenser pipe three parts form, described extraction tube comprises outer tube, the top of described outer tube is provided with the outer tube ground that is connected with condenser pipe, described outer tube bottom is connected with siphon pipe, be plugged with inner tube in the described outer tube, the upper end of described inner tube is arranged on the top of described outer tube ground, the lower end of described inner tube is provided with the inner tube ground that is connected with described solvent bottle, described inner tube ground is arranged on the below of described outer tube bottom, be provided with the core filter plate between described outer tube and described inner tube, described core filter plate is arranged on the top of described outer tube bottom, described inner tube comprises inner and outer wall, be provided with cavity between described inwall and outer wall, described inwall is provided with upper vent hole and lower passage, and described upper vent hole is arranged on the below of described outer tube ground, and described lower passage is arranged on the top of described outer tube bottom.
Compared with prior art, the invention has the advantages that a kind of inner tube leads directly to the heat collecting type apparatus,Soxhlet's, by solvent bottle, extraction tube, condenser pipe three parts form, extraction tube comprises outer tube, the top of outer tube is provided with the outer tube ground that is connected with condenser pipe, the outer tube bottom is connected with siphon pipe, be plugged with inner tube in the outer tube, the upper end of inner tube is arranged on the top of outer tube ground, the lower end of inner tube is provided with the inner tube ground that is connected with solvent bottle, and the inner tube ground is arranged on the below of outer tube bottom, is provided with the core filter plate between outer tube and inner tube, the core filter plate is arranged on the top of outer tube bottom, inner tube comprises inner and outer wall, is provided with cavity between inwall and outer wall, and inwall is provided with upper vent hole and lower passage, upper vent hole is arranged on the below of outer tube ground, and lower passage is arranged on the top of outer tube bottom; Because solvent vapour directly rises to the condenser pipe of upper end by inner tube, after condensation, be collected in the outer tube that extract is housed and extract, thereby can need to not rise to condenser pipe by outer tube or arm because of steam and cause distributing in a large number of heat, thereby make heat radiation slower, therefore overcome the defective of traditional apparatus,Soxhlet's fully; Again owing in the inner tube cavity interlayer being arranged, and there is passage that higher steam is filled in this cavity interlayer, the cavity interlayer has played the cushioning effect in the heat transfer process, both reached the effect of insulation steam, solvent is more easily gasified, also make heat partly pass to outer tube, extraction is controlled under the higher temperature to be carried out, both reached improve extraction efficiency purpose, also avoided heat steam to contact with the direct of outer tube, so that cause the boiling of solvent in the outer tube to affect carrying out continuously of extraction; Therefore the present invention is that a kind of heat radiation is slow, and temperature control is easy, the straight-through heat collecting type apparatus,Soxhlet's of the inner tube that extraction efficiency is higher.
