Description

The jar down-sampler

Affiliated technical field

The utility model relates to a kind of sampling thief, particularly relates to a kind of jar down-sampler for the pot liquid sampling.

Technical background

In the commercial production, the composition of the liquid in jar often needs instant sampling chemical examination, with the whether requirement up to specification of the composition of liquid in determining jar.At home, the general way of jar down-sampler is to go out three mouths at pot bottom, with pipeline sampling media is drawn outside the jar, the wobble pump of connecting is again sampled, its weak point is that the wobble pump that is adopted all is the outsourcing finished parts usually, its material is a carbon steel, and does not have anticorrosive measure, causes the sampling result of laboratory test not conform to the actual conditions easily and gives the misleading effect of having produced.

The utility model content

The purpose of this utility model is the weak point that overcomes at present used jar down-sampler, provides a kind of wobble pump to make with resistant material, makes sampling result of laboratory test and the actual jar down-sampler that conforms to.

The purpose of this utility model is achieved through the following technical solutions, the jar down-sampler is made up of ball float, stay pipe, top sampling pipe, middle part sampling pipe, bottom sampling pipe and sampling box, ball float, stay pipe, top sampling pipe, middle part sampling pipe and bottom sampling pipe are contained in the jar, top sampling pipe, middle part sampling pipe and bottom sampling pipe are banded on the stay pipe, and sampling box is contained in a jar outer position near the bottom.The lower end of top sampling pipe, middle part sampling pipe and bottom sampling pipe three sampling pipes all feeds in the sampling box; Sampling box is made up of casing, panel, support bar, top sample case inner connecting tube, middle part sample case inner connecting tube, bottom sample case inner connecting tube, three two one logical reflux in ball valve, ball valve, circulation adapter, sampling adapter, the case adapter, wobble pump feed pipe, wobble pump discharge nozzle and the wobble pump of switching.Panel links by support bar and casing, a top sample case inner connecting tube and a jar interior top sampling pipe link, a middle part sample case inner connecting tube and a jar interior middle part sampling pipe link, a bottom sample case inner connecting tube and a jar interior bottom sampling pipe link, three case inner connecting tubes of upper, middle and lower link with an end of two one direction changeover valves respectively, the other end of three two direction changeover valves is taken over circulation respectively and is linked, its the 3rd end and sampling are taken over and are linked, case external reflux pipe stretches into a jar end interior and that the interior backflow of case is taken over and links, the other end that backflow is taken in the case and an end of ball valve link, the other end of ball valve and wobble pump discharge nozzle link, one end of wobble pump feed pipe and the import of wobble pump link, and the other end and circulation are taken over and linked.Wobble pump is made up of cylinder body, piston, connecting rod, crank, two liquid in-out pipes, two liquid in-out mouths, piston is contained in the cylinder body, one end and the piston of connecting rod link, one end of the other end and crank links, the other end and the rocking arm of crank link, the two ends of cylinder body link with an end of liquid in-out pipe respectively, and the other end of liquid in-out pipe links with the liquid in-out mouth respectively.Wobble pump is made with resistant material (as stainless steel).

The utility model is compared with an at present used jar down-sampler, has because of wobble pump adopts resistant material and makes, so can not get rusty, makes the result of laboratory test and the actual coincidence of sample thief, can not bring the misleading effect to production.
