Description
Technical field
The utility model belongs to the check analyses technical field such as water conservancy, environment, medical treatment, industry, and in particular to a kind of micropore
The filtrate extraction element of membrane filtration.
Background technique
It in the check analyses such as water conservancy, environment, medical treatment, industry field, generally requires to recycle filtrate, in order to examine
Analysis uses, by taking deposit release experiment as an example, in order to analyze the pollution releasability of deposit, it is often necessary to design 1:5 water
The simulated experiment of native ratio detects the sediment pollution releasability under different operating conditions by extracting filtrate, and usually add
Overlying water content is in 10-50ml or so, in order to obtain representative sample, need to usually extract through centrifugation, filtering with microporous membrane,
For the filtrate content of recycling usually in 8-48ml or so, content is lower, and the preservation of its sample of different samples also has different need
It asks, filtrate recovery method/device common at present is mainly common funnel, cloth funnel, injecting type filter, vacuum filter system
System, wherein common funnel and cloth funnel filter membrane biggish for filter sizes（>0.45um）Effect is preferable, but for
0.45um and its miillpore filter below, since it passes through micro porous filtration by gravity, effect is poor, and the easy blocking of filtrate is micro-
Hole, so that filtering is then difficult to carry out, and injecting type filter is that miillpore filter is placed on inside syringe, by manually pushing
Syringe extracts filtrate, and this method spent time is long, and is easy to appear the broken situation of filter membrane, or even waste and test
Sample to be filtered out, vacuum filtering system create negative pressure by vacuum pump to promote membrane filtration, and filtrate can then recycle
In filtrate bottle, for a large amount of filtrate（200ml-2L）Extracting has preferable effect, but the micro filtrate of 10-50ml is mentioned
It takes, is difficult to ensure its extraction accuracy, this is because generally requiring rinse when cleaning filtering flask, at this time filtering flask inevitably can
Remaining cleaning fluid, it is assumed that only leaving 1ml cleaning solution, this is also to be difficult to receive for the extraction of micro filtrate, even if in addition, examination
It also needs in addition to be transferred to sample bottle after spline filter to filtrate bottle, filtrate residual is at this time inevitably had, so that the sample rate of recovery
It is lower, or even it is not able to satisfy the requirement of detection and analysis, and the secondary transferring of filtrate is also possible to that filtrate, to sum up, mesh can be polluted
It is preceding for micro filtrate（10-50ml）Extraction, high efficiency extraction, without transfer preservations in terms of also it is to be studied；Therefore it provides one
Kind of extraction effect is good, without secondary transferring, the filtrate of good, apparatus simplified, the easy to operate filtering with microporous membrane of sample adaptability
Extraction element is very important.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of extraction effect it is good, without two
It is secondary transfer, good, apparatus simplified, the easy to operate filtering with microporous membrane of sample adaptability filtrate extraction element.
What the purpose of this utility model was realized in：A kind of filtrate extraction element of filtering with microporous membrane, it includes NPB
Micro filtrate returnable bottle and bottle stopper, the micro filtrate returnable bottle of the NPB are fixed in filtering flask, the bottleneck of the filtering flask

Step 5：Pipe clamp is unclamped, sample bottle and filter base is separated, takes away miillpore filter；
Step 6：Take out the micro filtrate returnable bottle of NPB, saved on bottle stopper, record filtrate information, save filtrate with to
Analysis；
Step 7：Regular to put each component, so far individual sample filtrate is extracted and is terminated；
Step 8：Above step is repeated, next sample is extracted.
The beneficial effects of the utility model：The utility model forms negative pressure by the vacuum pump work that draws water in filtering flask,
To form pressure difference in miillpore filter two sides, and then sample filtration efficiency is improved, filtered filtrate is then stored directly in NPB
（Negative-pressure balancing）It in micro filtrate returnable bottle, can directly be saved after filtering in this way, without carrying out secondary turn to sample
It moves, in the case of sample is more, extra sample can be spilled over in filtering flask through through-hole on the micro filtrate returnable bottle of NPB and carry out
It collects；More sets filtering devices can be connected simultaneously by the pressure port of the vacuum pump that draws water in the application, to further increase

Material uses pressed cover bottle stopper；The micro filtrate returnable bottle of NPB is all directly saved directly as sample bottle after filtering every time, avoids sample
Secondary transferring；According to experiment needs, miillpore filter can choose the unlike materials such as glass fiber filter, acetate fiber filter membrane
Filter membrane, the filter membrane that different pore size also may be selected carry out the extraction of sample filtrate；NPB in the utility model（Negative-pressure balancing）Micro filter
The use of liquid returnable bottle realizes micro filtrate without the transfer purpose that can extract and save, avoid residual liquid with
Secondary transferring bring sample filtrate contamination；The utility model is poor using filter membrane pressure at both sides, may be implemented quickly to filter, and
Multiple groups filtering can be carried out simultaneously, be the check analyses such as water conservancy, environment, medical treatment, industry to improve the efficiency of sample filtration
Field provides convenient method；Total, the utility model is good with extraction effect, it is good to be not necessarily to secondary transferring, sample adaptability, fills
Set simplify, advantage easy to operate.
