Description
Technical field
The utility model relates to technical field of experiment equipment, utilizes decompression to realize the soxhlet type apparatus of efficient extracting specifically.
Background technology
Apparatus,Soxhlet's is a kind of refluxing extraction device, is usually used in plant extract or lipid extraction.Apparatus,Soxhlet's by heating, extracting and solvent recovery, cooling 3 Iarge-scale system form.Sample to be purified is dissolved with difference in different solvents, and impurity does not dissolve.Sample to be extracted is wrapped in fat-free filter paper bag, after bandaging, put into the sleeve pipe that rope is carried, connect cucurbit and condenser pipe.Regulate suitable condensed water flow velocity, heating is containing extractant cucurbit, and after boiling, solvent vapo(u)r rises through wireway, be condensed in liquid instillation sleeve pipe, infiltrate sample, when sleeve pipe internal solvent liquid level exceedes siphonal highest point, namely there is siphon, flow in cucurbit.The solvent flowed in cucurbit continues distillation, condensation, backflow, so moves in circles, make solid matter constantly extract by pure solvent, by the material collection after extracting in cucurbit.But existing exist single extraction times length, inefficient problem.
Utility model content
The purpose of this utility model is, inefficient problem long for extraction times, provides a kind of efficient Soxhlet extraction device, and basis is novel realizes the effect of Rapid extraction by pressure in reduction equipment.
For achieving the above object, the technical solution adopted in the utility model is: a kind of efficient Soxhlet extraction device, comprise cucurbit, sleeve pipe and condenser pipe, described cucurbit is connected with the lower end of sleeve pipe by frosted mouth, described sleeve upper end is connected with the lower end of condenser pipe by frosted mouth, described sleeve outer wall is provided with siphon pipe and wireway, described sleeve bottom is provided with filter screen, the upper end of described condenser pipe is connected with vavuum pump and venting valve respectively by three-way pipe, is provided with anti-suck bottle between described vavuum pump and three-way pipe.
Further, described condenser pipe is provided with water inlet and delivery port.
This novel Advantageous Effects is: this is novel can make to form negative pressure in device owing to being provided with vavuum pump and venting valve, owing to there is the boiling of negative pressure accelerated solvent, makes that solvent vapo(u)r rises, the speed of condensation and backflow accelerates and then improve its extraction efficiency; In addition, negative pressure can reduce the boiling point of solvent, to avoid in extraction process active material Yin Gaowen or extraction time long and destroyed, also can pressure size in flexible modulation device, for the suitable Extracting temperature of different solvent selection and pressure.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of efficient Soxhlet extraction device, comprise cucurbit 1, sleeve pipe 2 and condenser pipe 6, cucurbit 1 is connected with the lower end of sleeve pipe 2 by frosted mouth, and sleeve pipe 2 upper end is connected with the lower end of condenser pipe 6 by frosted mouth, and sleeve pipe 2 outer wall is provided with siphon pipe 4 and wireway 3, filter screen 5 is provided with bottom sleeve pipe 2, the upper end of condenser pipe 6 is connected with vavuum pump 7 and venting valve 8 respectively by three-way pipe, is provided with anti-suck bottle 9, avoids gas backstreaming between vavuum pump 7 and three-way pipe.
The vavuum pump that three-way pipe connects can be used for the gas in draw-out device, and venting valve can be used for gas in bascule.When pressure drops to certain numerical value in extraction element, by regulating venting valve, vavuum pump is bled identical with valve intake velocity of exitting.
Wherein, condenser pipe 6 is provided with water inlet and delivery port.
Application example, Antibacterial Constituents in alcohol extract Cortex Magnoliae Officinalis: accurately take through pulverizing, dry bark of official magnolia sample 10.000g, rear being directly placed in sleeve pipe is bandaged with fat-free filter paper and cotton thread, its lower end tipping has the cucurbit of 300.0mL absolute ethyl alcohol (under normal pressure boiling point 78 DEG C), connect circulating condensing water, open water bath, close venting valve, open vavuum pump, when pressure reduces to 0.1MPa, slowly open venting valve, make the vavuum pump speed of evacuation identical with venting valve intake velocity, alcohol boiling is just observed when temperature is raised to 50 DEG C, steam rises, condensation, becoming to be dropped into is equipped with in the sleeve pipe of sample, when sleeve pipe internal solvent liquid level is higher than siphon pipe height, the active ingredient extracted is siphoned in cucurbit with solvent.So move in circles, by the material collection that extracts in cucurbit.By the rising of accelerating alcohol steam, condensation and backflow, extraction time is shortened, extraction efficiency improves greatly.
The utility model, by the pressure regulation effect of vavuum pump with venting valve, can also be applied to the extraction test such as ethyl acetate, acetone, benzinum and ether.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
