Abstract
The utility model relates to an alternative device of a Soxhlet extractor. The alternative device comprises a condenser, an extractor and an extraction bottle, wherein a steam raising branch tube, which is communicated with a chamber and inclines downwards, is arranged on the side wall of the extractor; two connectors are arranged above the extraction bottle; one of the connectors is connected with the steam raising branch tube while the other connector is connected with the outlet of the extractor. According to the alternative device of the Soxhlet extractor, an original single-opening flask is changed into a two-neck bottle as the extraction bottle, the extractor with the steam raising branch tube and an extract return branch tube on two sides is adopted to replace an extractor with a siphon on the side surface, and thus the problems that the siphon on the extractor is likely to be blocked and broken, materials cannot be sufficiently soaked and the like in a conventional experiment are solved.
Description
Technical field
The utility model relates to a kind of alternative of cable type extractor according, belongs to a kind of glass equipment of use for laboratory.
Background technology
From solid matter, a kind of method of extract compounds is utilized solvent exactly by solid matter long period of soaking and by needed material lixiviate out, i.e. long-term lixiviation process.But this method spended time is longer, and solvent load is also larger, efficiency is not high yet.
For addressing the above problem, laboratory adopts extraction equipment for fat (claiming again cable type extractor according) to extract solid matter more at present.Cable type extractor according is comprised of extraction flask, extractor (side is with siphon pipe), condenser three parts.It is to utilize solvent refluxing and siphon principle, and solid matter is continuously extracted by solvent, thereby extraction efficiency is higher.Before extraction, first by the solid matter porphyrize being extracted, the area infiltrating to increase solvent, is then placed on solid matter in filter paper cover, is placed in extractor, and the lower end of extractor is connected with the extraction flask that fills solvent, and upper end connects condenser.When solvent seethes with excitement, steam rises by steam pipe, and the device that is then condensed is condensed into liquid, splashes in extractor, and when solvent liquid level surpasses the siphonal peak on extractor, i.e. siphon is flowed back in extraction flask, extracts the part material that is dissolved in solvent simultaneously.Utilize like this solvent refluxing and siphonage, the lyotrope matter in solid matter is enriched in extraction flask, then, then the material of extraction is separated from solvent.
Although current cable type extractor according can extract solid matter effectively, simultaneously also there are the following problems: the siphon pipe of (1), extractor side is thinner, often there will be the siphon pipe phenomenon that fractures in assembling instrument and use procedure; (2), siphon pipe is not only thin, and has certain flexibility, during extraction, often can stop up, cannot take out by extract; (3), because repeatedly being soaked to expand by solvent, often there is exceeding siphonal highest point in material barrel that extract is housed in extraction process, cause the material being extracted not to be fully immersed in solvent, and extraction yield declined.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of alternative of cable type extractor according, the alternative of this cable type extractor according transforms original single port flask into two neck bottles to be made extraction flask, with both sides, replaces side with siphonal extractor respectively with the backflow extractor of arm of steam rising arm and extract, has solved in current experiment the problems such as easily stifled, easily broken, material immersion is insufficient of the siphon pipe on extractor.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of alternative of cable type extractor according, comprises condenser, extractor and extraction flask.On the sidewall of extractor, be provided with communicate with cavity and be tilted under steam rising arm; Above extraction flask, be provided with two interfaces, one of them interface is connected with steam rising arm, and another interface is connected with the outlet of extractor.
The bottom of described extractor is divided into extracts cylinder, and the below of extracting cylinder is the extract arm that backflows, and backflows in the cavity that arm is connected and is provided with the glass filter disc with hole extracting cylinder and extract, on extract backflows arm, is provided with rotary switch.
Interface between described condenser, extractor and extraction flask all adopts ground plug-in type connected mode.
The utility model transforms original single port flask into two neck bottles to be made extraction flask, with both sides, replaces side with siphonal extractor respectively with the backflow extractor of arm of steam rising arm and extract, solved in current experiment the siphon pipe on extractor easily stifled, easily broken, material soak the problems such as insufficient, simultaneously, because this device can guarantee fully contacting of the material that is extracted and solvent, improved extraction yield.
Accompanying drawing explanation
Fig. 1 is the structural representation of the alternative of cable type extractor according.
The specific embodiment
As shown in Figure 1, a kind of alternative of cable type extractor according, comprises condenser 1, extractor 5 and extraction flask 10.It is characterized in that: on the sidewall of extractor 5, be provided with communicate with cavity and be tilted under steam rising arm 9; Above extraction flask 10, be provided with two interfaces 11, one of them interface 11 is connected with steam rising arm 9, and another interface 11 is connected with the outlet of extractor 5.
The bottom of described extractor 5 is divided into extracts cylinder 6, and the below of extracting cylinder 6 is the extract arm 8 that backflows, and backflows in the cavity that arm 8 is connected and is provided with the glass filter disc 12 with hole extracting cylinder 6 and extract, on extract backflows arm 8, is provided with rotary switch 7.
Interface between described condenser 1, extractor 5 and extraction flask 10 all adopts ground plug-in type connected mode.
Operation principle of the present utility model is: without using filtration paper cylinder, on the glass filter disc 12 that extracts cylinder 6 bottoms, put a little cotton, then the extract of porphyrize is placed directly in and extracts in cylinder 6, in extraction flask 10, put into solvent, and add several zeolites, connect successively extraction flask 10, extractor 5 and condenser 1, open the upper and lower mouth of a river 2,3, start heating.When solvent seethes with excitement, the steam rising arm of the steam of solvent on extractor rises, then after the device that is condensed is cooling, turn back to and extract in cylinder, when the extract height in extracting cylinder approaches the upper port of the steam rising arm on extractor, open the rotary switch 7 that extract backflows on arm 8 extract is put back in extraction flask, then, then close rotary switch 7, so repeat this operation, until extraction completely.
