Description

A kind of fluid sampling device

Technical field

The utility model relates to a kind of fluid sampling device, particularly a kind of fluid sampling device on short transverse, existing concentration or composition to change.

Background technology

As far as the most sampling liquid that needs, this solution of liquid as all directions concentration, distributed components, or approximately think that it is evenly distributed.Only need extract wherein any part to such liquid sampling and all can represent liquid to be taken a sample.

But; Some liquid (like the ammonium molybdate solution of metallurgy industry) is through behind the certain hour; Its composition or concentration can change on short transverse; When liquid on short transverse during no obvious layering or layer height not fixedly the time, this class I liquid I is carried out accurately the sample analysis very difficulty that will become.

According to present common way, the one, ignore the variation on short transverse of liquid component or concentration, the sampling method sampling of pressing regular solution detects; The 2nd, sampling is respectively represented liquid whole detection index with the mean value of a plurality of kinds testing results on differing heights.

To common way one, its defective is on short transverse, to change when big when liquid component or concentration, and the actual conditions deviation of institute's sample thief and liquid is very big, and taking a sample does not have representativeness and practical significance.

To common way two, the sampling result of this method still possibly exist than large deviation, and multidraw is very inconvenient, and workload is bigger.

The utility model content

The purpose of the utility model is to provide a kind of fluid sampling device, and it can exist the liquid that changes to take a sample on short transverse to composition or concentration effectively.

For this reason, the utility model provides a kind of fluid sampling device, it is characterized in that; Comprise sleeve pipe, soft water absorptivity tube core and bottom; Said tube core places in the said sleeve pipe, and the outside surface of tube core and the inside surface of sleeve pipe are fitted, and the bottom of tube core is concordant with the bottom of sleeve pipe; The end face of tube core is lower than the top of sleeve pipe; Bottom matches with sleeve pipe.

Preferably, sleeve pipe longitudinally is made up of two parts, and these two parts surround tubulose through faying face, and sleeve pipe is provided with a narrow slit on whole height; Said fluid sampling device further comprises the top fixed cover, and sleeve pipe and tube core are fixed by the top fixed cover at least.

Preferably, said sleeve pipe is cylindric; On the surface of said sleeve pipe, the axis direction of the said sleeve pipe in edge is provided with a series of through hole.

Preferably, sleeve pipe is processed by steel pipe, and tube core is processed by collodion.

Preferably, said soft water absorptivity tube core is made up of multistage, one-tenth random length capable of being combined.

Preferably, the width of said narrow slit is 1-5mm.

Preferably, the xsect of said sleeve pipe and soft water absorptivity tube core is rounded.

This device adopts the vertical insertion of water absorptivity tube core liquid to be taken a sample; Guaranteed that composition or the CONCENTRATION DISTRIBUTION on short transverse of liquid in the tube core is consistent with the actual distribution situation of the liquid of waiting to take a sample, and is suitable for there being the sampling of concentration or composition variation liquid on the short transverse.

Description of drawings

Fig. 1 is the structural representation according to a kind of fluid sampling device of the utility model.

Fig. 2 is along the cross-sectional view of A-A to intercepting in Fig. 1.

Embodiment

Below in conjunction with accompanying drawing 1-2 the embodiment of the utility model is done further detailed description.

Shown in Fig. 1-2, the sleeve pipe 1 of this sampler and the xsect of tube core 2 are circular, and tube core 2 can be by the collodion material of good water absorption.Sleeve pipe 1 can be by steel pipe manufacturing; Form the approximate pipe 11,12 of partly cuing open of two blocks of sleeve pipe 1 and surround tubulose through faying face 13; Be connected fixingly through engage thread by bottom 3 and top fixed cover 4, sleeve pipe 1 leaves a narrow slit 5 on whole length, and liquid can be absorbed by tube core 2 through narrow slit 5.The bottom of tube core 2 is concordant with the bottom of sleeve pipe 1, the length of tube core 2 with wait the consistent of liquid height of taking a sample, slightly shorter than the total length of sleeve pipe 1.In Fig. 1, the end face 20 of tube core 2 is lower than the top of sleeve pipe 1.

When there are liquid (as the ammonium molybdate solution after the leaving standstill) sampling that changes in concentration or composition on short transverse; Sampler is vertically inserted liquid and keeps a period of time (general more than 10 minutes); Treat that the narrow slit 5 of liquid through sleeve pipe 1 gets into tube cores 2 and when on sustained height, being evenly distributed, fast sampler is extracted out.After the liquid drip-dry of sleeve pipe 1 outer wall or drying, outward winding bottom 3 and top fixed cover 4 are taken sleeve pipe 1 apart, take out tube core 2.The liquid that tube core 2 is absorbed is clamp-oned the container of splendid attire sample, promptly accomplishes primary sample.

The purpose that bottom 3 is set is that also when extracting sampler out, the liquid and the die bottom that reduce differing heights absorb the mass transfer between liquid.

According to a preferred embodiment of the utility model, fluid sampling device mainly is made up of sleeve pipe, soft water absorptivity tube core, bottom and top fixed cover.Sleeve pipe is made up of two blocks of approximate pipes that partly cut open, and two approximate partly cuing open when pipe synthesizes sleeve pipe are left a narrow slit on whole casing length, be fixed into sleeve pipe through bottom and top fixed cover.Tube core is contained in the sleeve pipe, and tube core outside surface and internal surface of casing are fitted, and die bottom is concordant with sleeve bottom, and tube core length is consistent with the liquid height of waiting to take a sample.

Sampling method is: insert in the liquid of waiting to take a sample sampler is vertical, sleeve bottom is concordant with the liquid bottom surface of waiting to take a sample, after a period of time (liquid that the time is enough to guarantee the tube core absorption and co-altitude wait to take a sample liquid consistent); Sampler is extracted out fast; Drip-dry or dry the outer liquid of sleeve pipe after, sleeve pipe is pulled down, take out tube core; Liquid in the tube core is extruded into sample container, promptly accomplishes sampling.

Under the inspiration of the utility model thought, those skilled in the art also possibly expect other embodiment.

For example, sleeve pipe 1 is not two and half, but whole, but all be covered with aperture up and down;

Again for example, tube core 2 can not take out, and increases an element of extruding that is similar to syringe piston, is used to extrude sample liquid;

Again for example, bottom 3 and top fixed cover 4 one of at least can be fixing with sleeve pipe 1 through engage thread, also can pass through bayonet socket mode, fast-assembling flange connection etc. and fix with sleeve pipe 1.Particularly, bottom 3 and sleeve pipe 1 fixed form can be different from the fixed form of top fixed cover 4 and sleeve pipe 1.

Yet the embodiment of these variations has been included within the protection domain of claims of the utility model.
