Description
【Technical field】：
Experimental analysis field is the utility model is related to, particularly for laboratory liquid solid extraction pre-treatment analytical equipment, is related to
A kind of and reflux extraction bottle.
【Background technology】：
The pretreatment process such as generally to extract, purify, concentrating before detection and analysis, and before liquid-solid extraction is the most universal
Processing mode.According to Environmental Protection Agency analysis method EPA3540C, liquid-solid extraction common equipment is apparatus,Soxhlet's.Surname extraction
Device is a kind of extraction equipment for having centuries history, and it has the advantages of technology maturation is reliable, but also has structure composition complexity,
The shortcomings that relatively complicated is operated, especially because the abstraction pool of apparatus,Soxhlet's, which is located at container firing equipment top, more than ten centimetres
Height, and temperature is not high after extractant is condensed so that under extraction efficiency is relatively low, the up to a hundred circulations of a few hours tens need to be passed through
It can be only achieved the satisfied rate of recovery.Some improve that liquid are fixed standby to equally exist similar defect, such as food analysis in the market
Conventional extraction equipment for fat equally exist composition it is more complicated, using it is inconvenient the shortcomings that.
Thus, develop one kind can quickly, efficiently, easily liquid-solid extraction equipment seems necessary.It is of the invention special
A kind of reflux extraction bottle for experimental analysis liquid-solid extraction is not devised, and the design invention can greatly improve liquid-solid extraction effect
Rate, the detection pre-treatment time is saved, improve extraction efficiency, the invention had both had the mature and reliable of apparatus,Soxhlet's, had again very
More expanded functions, and it is simple in construction, and manufacturing cost is low, easy to use, and apparatus,Soxhlet's can be used as in numerous experimental analyses
Alternate device.
【The content of the invention】：
Formed for existing liquid-solid extraction device structure it is complicated, it is cumbersome the shortcomings that, the utility model particularly will be molten
Agent cooking-vessel carries out integrated design with abstraction pool, realizes structure simplification and the raising of extraction efficiency, the shape of the utility model
Shape, structure and the technical scheme taken are as follows：
A kind of reflux extraction bottle, it is characterised in that：Including long-neck bottle (1), groove type abstraction pool (2), siphon pipe (3).
Long-neck bottle has frosted bottleneck, and its bottom is put down, middle hollow out.Groove type abstraction pool is embedded in flask body, its
It is open and extends to form interior edge to medial axis.Siphon pipe is connected with groove type abstraction pool, and mouth of pipe one end is close to groove type abstraction pool
Interior bottom, other end bottom in flask body.All building blocks are resistant to elevated temperatures quartz glass material, with condensing reflux
Efficient liquid-solid extraction device is formed after pipe, electric hot plate connection, it is easy to use.
In the shape and structure such as Fig. 1 of long-neck bottle shown in (1), its bottleneck inner surface is frosting, connects condensing reflux
Pipe forms sealing, and for long-neck bottle to be flat, the bottom center portion 1.0-1.2CM that raises up forms hollow, groove type abstraction pool
It is placed in flask body in the projection at bottom, is not directly heated.
The shape and structure of groove type abstraction pool (2) are as shown in figure 3, groove type abstraction pool is embedded in the interior bottom of long-neck bottle
Projection on, melt one with long-neck bottle, its upper opening extends to form interior edge to axis, avoids the sample extracted wherein
Jumped out during vibration.Groove type abstraction pool is placed in flask body, can be heated plate heating during extraction indirectly, solvent vapo(u)r also can be fast
Speed heating extract simultaneously keeps the extraction temperature close to solvent boiling point, and the extraction temperature apparatus,Soxhlet's more external than abstraction pool is high,
So as to improve rate of extraction.
Siphon-shaped and structure are as shown such as (3) in Fig. 1, and siphon pipe is connected with groove type abstraction pool, and mouth of pipe one end is close
Bottom in groove type abstraction pool, other end bottom in flask body；When the solvent in groove type abstraction pool goes up to siphon pipe
During extreme higher position, extract is flowed into flask from siphon pipe, forms siphon.
Helpfulness effect：This is applicable new for laboratory liquid solid extraction pre-treatment analysis, and it is real mainly to solve liquid-solid extraction
It is complicated to test middle traditional apparatus,Soxhlet's composition, the problem of cumbersome extraction efficiency is low, for apparatus,Soxhlet's, this backflow
The operating temperature of extraction flask is high, and because of groove type abstraction pool volume ratio apparatus,Soxhlet's small, faster, it has rope to cycle rate
The mature and reliable of family name's extractor, possess higher extraction efficiency again, and its is simple in construction, manufacturing cost is low, easy to use, in crowd
Can be as the alternate device of apparatus,Soxhlet's in more experimental analyses.
【Brief description of the drawings】
Fig. 1：The utility model floor map：1 long-neck bottle；2 groove type abstraction pools；3 siphon pipes.
Fig. 2：The utility model left view.
Fig. 3：The stereo amplification figure of the utility model groove type abstraction pool and siphon pipe.
【Embodiment】
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
Embodiment 1
In laboratory hood, the sample that need to be extracted is wrapped with filter paper, groove type extraction is put into from long-neck bottle body and bottleneck
Take in pond, be subsequently poured into extractant, the utility model is placed in heating plate, heating-up temperature is mixed up according to solvent boiling point, so
Reflux condensing tube is connected in long-neck bottle bottle mouth position afterwards, connects condensed water.The heated boiling of extractant, steam rise to condenser pipe
It is transformed into liquid solvent to drip downward into groove type abstraction pool, sample is constantly extracted by fresh solvent, when in groove type abstraction pool
Solvent when going up to siphon pipe extreme higher position, extract is flowed into flask from siphon pipe, forms siphon, liquid level is extracted in pond
Siphon pipe opening is dropped to, stops siphon, until new extractant constantly instills from reflux condensing tube, forms a new round
Siphon, so circulation sample is extracted.After extraction, extract can directly be poured out from reflux extraction bottle bottleneck,
Carry out subsequent experimental operation.
Embodiment 2
If the boiling point of extractant is less than the boiling point of water, the heating plate of above-mentioned experiment can be changed into water-bath, also may be used
The utility model is placed in ultrasonic extracting machine and carries out heating water bath, can so carry out reflux extraction and ultrasonic extraction simultaneously
Process, further improve extraction efficiency.
