Description
Technical field
This utility model belongs to microorganism sampling technique field, down-hole, is specifically related to a kind of down-hole microorganism sampler.
Background technology
At present, the microbe sampling in coal bed gas well, well, oil well liquid mainly discharges liquid acquisition by well head.This method of sampling is typically to discharge well head liquid and collects and directly obtain microbiological specimens.But under conditions of external environment is relatively more severe such as strong wind, airborne dust etc., it is easy to cause sample contamination.When in liquid, micro organism quantity is less, institute's sample thief is difficult to meet requirement without filtration.And if sometimes anaerobism require higher, traditional take liquid and filter type just easily causes microorganism ingress of air and dead, sampling quality cannot reach requirement.
Summary of the invention
This utility model in order to overcome existing microbe sampling method easily cause sample contamination, can not reach anaerobism require, the problem such as the less deficiency of micro organism quantity in sample, it is provided that a kind of down-hole microorganism sampler.
This utility model adopts the following technical scheme that
A kind of down-hole microorganism sampler, has the closed reservoir of inlet, the top of reservoir and inside hypomere and is respectively equipped with check valve including bottom, and the inside epimere of reservoir is provided with microporous filter membrane, is containing liquid chamber for cavity below microporous filter membrane.
Described microporous filter membrane is fixed by microporous filter membrane pad, and microporous filter membrane pad is located at above microporous filter membrane and is fixed on reservoir inwall.
It is provided with filter screen in described inlet.
Described reservoir is cylindrical.
Utilizing sampling apparatus described in the utility model, whole sampling process not ingress of air, will not be polluted by from air, meet the requirement of anaerobism, the sample microbial quantity of acquirement is many, improves microorganism concn in sample, and its simple in construction, is suitable for promoting the use of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1-pushes up check valve, 2-microporous filter membrane pad, check valve at the bottom of 3-, 4-inlet, 5-reservoir, 6-microporous filter membrane, 7-containing liquid chamber, 8-filter screen.
Detailed description of the invention
In conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Microorganism sampler in down-hole as depicted, uses a cylindrical sampler, is linked together by inlet and reservoir and formed.Being inlet 4 bottom sampler, top is reservoir.A filter screen 8 is had in inlet 4.Reservoir two ends are respectively arranged with a check valve (1,5), can make that liquid is unidirectional to be passed through.In reservoir, there is microporous filter membrane pad 2 upper position, is fixed in liquid storage wall bucket.Microporous filter membrane pad is fixed with microporous filter membrane 6 for 2 times, and microporous filter membrane less than 6 is containing liquid chamber 7.During sampling, this device is submerged in liquid to be sampled, liquid is removed solid impurity granule by inlet strainer filtering, check valve bottom reservoir enters containing liquid chamber again, after filtering with microporous membrane, microorganism is trapped in the containing liquid chamber of microporous filter membrane bottom, liquid without microorganism, through microporous filter membrane and microporous filter membrane pad, is discharged by the check valve at containing liquid chamber top.
