Description
Technical field
The present invention relates to liquid layered sampling column, be applicable to all liq sampling, belong to analytical chemistry sampling technique field.
Background technology
Present environmental protection analytical sampling is still from analyzed liquid surface sampling, such sampling is for the sample analysis in liquid with different specific weight material or contaminated stratified liquid, do not have tangible representativeness, the result of sample analysis does not have authenticity so in other words; Therefore, liquid sampling will will be also not only the different depth sample analysis of liquid from the different liquids layer of liquid from different liquid surface arda samplings, and the liquid sample taking out is like this just representative; But now both at home and abroad can be from the grab sampling device of the different depth sampling of liquid, the present invention is exactly a kind of simple sampler that can different depth samples simultaneously from liquid of striving above-mentioned present situation invention.
Summary of the invention
The object of this invention is to provide a kind of can be with entering from the liquid layered sampling column of the different depth layer stratified sampling of liquid.
Liquid layered sampling column, comprises a sample storage post and a pull bar and many exhaust kapillaries; It is characterized in that:
1, sample storage post is separated into the sample storage chamber that a plurality of length is the same, a small ball is equipped with in each sample storage Shi the same side, small ball revolves handle by a ball valve and small ball liquid inlet forms, when ball valve revolves horizontality perpendicular to sample storage post axis, ball valve is closed condition, and it is opening that ball valve revolves ball valve when plumbness is parallel to sample storage post axis; Pull bar is positioned at sample storage post jamb outside and is parallel to sample storage post axis, on pull bar, there are a plurality of pulling buckles alive, the position of each pulling buckle of living is corresponding with small ball, the ball valve of small ball revolves being enclosed within the pulling buckle alive on pull bar, while up lifting pull bar with hand, drive ball valve to revolve turning clockwise and progressively opening small ball, while down pushing pull bar with hand, ball valve revolves being rotated counterclockwise and closing small ball; Small ball is arranged on the position that each sample storage Shi lower end approaches sample storage chamber, bottom, sample storage chamber demarcation strip, each sample storage Shi upper end is that the sample storage chamber demarcation strip downside on top, sample storage chamber is provided with an exhaust kapillary, exhaust kapillary extends up to sample storage Zhu top along sample storage post, and opening upwards.
2, the pulling buckle of living is fixed on pull bar by rotating shaft, the pulling buckle of living is by rotating shaft, the pulling buckle of living plate, live and draw handle, live and draw a spin axis and screw to form, rotating shaft and the pulling buckle plate of living are structure as a whole, rotating shaft can be rotated on pull bar, the pulling buckle of living plate can rotate spin axis around living in drawing, live in drawing and revolve and ball valve is revolved slidably reciprocating under the pulling buckle plate of living fastening ball valve, when pull bar upwards lifts, drive ball valve to revolve turning clockwise, and ball valve is revolved doing certain slip and open small ball in work pulling buckle plate, when pull bar pushes downwards, drive ball valve to revolve being rotated counterclockwise, and ball valve is revolved doing certain slip and close small ball in work pulling buckle plate.
3, the connecting pipe bore that each sample storage chamber is connected with small ball is different, the connecting pipe bore that its sample storage chamber, the sample storage chamber on the sample storage Shi Dao top of Qie Cong bottom is connected with small ball increases gradually, this is because when sampling, sample storage post vertically stretches in sampled liquid, the suffered fluid pressure of each small ball is different, the fluid pressure suffered from darker its small ball of liquid surface distance is just larger, the connecting pipe bore that its sample storage chamber is connected with small ball is just less, so just can guarantee when sample storage post samples, the liquid volume that enters sample storage chamber from each small ball as many, thereby the liquid sampling quantity that can realize different depth is identical.
The present invention compared with prior art has the following advantages:
1, the real different depth liquid sampling from sampled liquid of the present invention.
2, the volume that the present invention takes out liquid sample from different depth liquid is identical, thereby makes its sampling have the representativeness of liquid.
3, the present invention is simple in structure, with low cost, and operation is succinct, and service free can large area be used.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the embodiment of the present invention;
Fig. 2 is middle pulling buckle schematic diagram alive embodiment illustrated in fig. 1.
In Fig. 1-2: 1, pull bar handle 2, pull bar 3, exhaust kapillary 4, Capillary restrictor mouth 5, small ball 6, the pulling buckle 7 of living, ball valve revolve 8, ball valve revolves labour contractor 9, sample storage chamber demarcation strip 10, sample storage chamber 11, sample storage post jamb 12, small ball liquid inlet 13, screw 14, rotating shaft 15, the pulling buckle of living plate 16, live and draw a spin axis 17, live and draw handle.
Embodiment
In the embodiment shown in Fig. 1-2: liquid layered sampling column, when sampling, by sample storage post at leisure, vertically stretch into lightly in sampled liquid, and extend into liquid depths as far as possible, but not have suitable for reading being as the criterion of exhaust kapillary 3 of sample storage post upper end, silently await 1 minute motionless, then with hand, lift lightly pull bar handle 1, pull bar 2 drives each ball valve revolve 7 rotations and open gradually each small ball 5, sampled liquid flows to each sample storage chamber 10 through each small ball 5, each sample storage chamber 10 is when small ball 5 flows to liquid, the gas of sample storage chamber 10 is rushed for to exhaust kapillary 3, and make sample storage chamber 10 can be full of quietly the liquid flowing to through exhaust kapillary 3 discharge sample storage chambers 10, until enter the upper end of the liquid levels position arrival exhaust kapillary 3 of sample storage chamber 10 from small ball 5, be that the exhaust kapillary 3 of a uppermost sample storage chamber 10 apical position surroundings is can see the liquid of rising time, press lightly pull bar handle 1, pull bar 2 promotion ball valves are revolved and 7, be rotated counterclockwise and close small ball 5, then mention lightly sample storage post and keep the plumbness of sample storage post, sampling completes, turn on respectively each alive drawing the screw 13 on 17, and open to live in drawing and 17, ball valve is revolved 7 disengaging work are drawn and fastened and the push-and-pull action of pull bar 2 17, outward winding one by one each small ball 5 liquid of getting in each sample storage chamber 10 is put into respectively in the container of appointment, waits for analytical test.
