Abstract

The utility model discloses a vacuum sampler, which comprises an inlet 1 connected with a vacuum pipe, the inlet 1 is connected with the upper part of a sampler main body 3 through a first valve 2, the bottom end of the sampler main body 3 is connected with an outlet 5 of the sampler through a second valve 4, a sight glass 6 at the upper part of the second valve 4 is connected with the bottom of the sampler main body 3, the sight glass 6 is connected with the sampler main body 3 through a third valve 7, and the upper part of the sight glass 6 is connected with an air filter 9 through a fourth valve 8.

Description

A kind of vacuum sampler

Technical field

The utility model belongs to pharmacy or foodstuff manufacturing device field, relates to a kind of vacuum sampler specifically.

Background technology

In food or medicine manufacture process; need online sampling through regular meeting; but the ducted working fluid sampling of against vacuum often needs production run to pause; negative pressure in the pipeline is removed and could be taken a sample; during perhaps online sampling; sampling amount is excessive can not to return vacuum pipe again with unwanted sample, causes unnecessary waste.

Summary of the invention

For solving the problems of the technologies described above, the utility model provides a kind of vacuum sampler.

Vacuum sampler described in the utility model is realized in the following way:

Vacuum sampler described in the utility model, comprise the inlet 1 that links to each other with vacuum pipe, inlet 1 joins by valve 1 and sampler main body 3 tops, sampler main body 3 bottoms join by valve 24 and sampler outlet 5, look handleless cup 6 links to each other with sampler main body 3 bottoms on valve 24 tops, look handleless cup 6 and join, look handleless cup 6 tops and join by valve 48 and air strainer 9 by valve 37 and sampler main body 3.

During the utility model sampling, close four valves, inlet 1 passes through chuck, the sample tap that has valve on socket or spiral ways of connecting and the vacuum pipe joins, open the valve on the vacuum pipe, slowly open valve 1 again, sampler main body 3 internal pressures with the pressure equilibrium in the pipeline after, fluid sample flows to sampler main body 3 gradually by action of gravity, because looking handleless cup 6 makes for transparent material, can observe the height of liquid in the sampler by looking handleless cup 6, reach after the amount that needs valve-off 1, open valve 37 and valve 48 more successively, sampler is inner can be communicated with by air strainer with outside atmosphere, but after getting closed container and outlet 5 being connected, opens valve 4 again, emit capacity for the sample that detects after valve-off 24 and valve 38, opening valve 1, the remaining liq sample in the sampler can be gone into vacuum pipe by resorption, owing to be provided with air strainer 9, therefore can not cause the pollution of liquid in the pipeline, effectively prevent the waste of sample simultaneously yet.

As preferred version, the handleless cup of looking of the present utility model has scale on 6, can more accurate observation sampler in the height of liquid level, accomplish that sampling is accurately.

Another preferred version is that sampler main body of the present utility model 3 inside are connected suction pipe 10 with inlet, suction pipe 10 extends to sampler main body 3 bottoms, when sampler main body 3 is thick, may cause remaining liq sample resorption comparatively difficult to vacuum pipe, the inventor designs the structure of suction pipe 10 for this reason, can make the resorption of remaining liq sample more complete like this.

Another preferred version is that the aperture of the air strainer 9 in of the present utility model is less than or equal to 0.22 micron, because the diameter of the bacterium that has been found that now is all greater than 0.22 micron, therefore, the aperture of air strainer 9 is less than or equal to 0.22 micron, makes it can prevent effectively more that in blocks dust bacterium from entering vacuum pipe.

In a word, this vacuum sampler is easy to use, cost is not high, can effectively solve the variety of issue when taking a sample in the vacuum pipe, sampling accurately, do not waste sample, more can prevent in the production run, can be widely used in the sampling in the vacuum pipe of medicine and food manufacturing industry because sampling detects the pollution that causes.
