On the radiosodium loop, take a sample, technical more complicated, the design that Russia provides (CEFR reactor-loop sampler instructions, 2002) has solved the method for the safety sampling of radiosodium.Advantages such as whole sampler has good seal performance, and sampling operation is convenient, can long-rangely take a sample, and the sampling operation time is short.But the existence owing to oxygen in the glove box and water can cause that impurity reacts with oxygen, water respectively in the sodium, generates new impurity, thereby the sodium sample vulnerable to pollution is brought difficulty to accurate analysis of impurity in the sodium, also can cause the pollution of a loop sodium simultaneously.
Summary of the invention
Contaminated for fear of sodium sample, improve the accuracy of impurity analysis in the sodium, and do not cause the pollution of loop sodium, former design is improved, link to each other with the gas circulation cleaning system by glove box, thereby can overcome above-mentioned shortcoming.
The utility model provides a kind of sampler, contain sampling container 1, cooling section 5, glove box 7, sample hoisting gear 10, transfer vessel 16 and cask 12, wherein, sampling container 1, cooling section 5, glove box 7, sample hoisting gear 10 is linked in sequence from bottom to top, and transfer vessel 16 is positioned at sampling container 1, be connected with sample hoisting gear 10 by nickel flap 18, cask 12 is positioned at glove box 7 sides, between sampling container 1 and the cooling section 5 primary seal 3 is arranged, and between cooling section 5 and the glove box 7 lower seal 6 is arranged, between glove box 7 and the sample hoisting gear 10 top seal 9 is arranged, sealing 13 is arranged between glove box 7 and the cask 12, and sample hoisting gear 10 passes whole sampler, and this sampler also contains the gas circulation cleaning system, this gas circulation cleaning system is positioned at outside the glove box 7, the two ends of system and glove box 7 body welded seals.
This gas circulation cleaning system contains gas meter 25, gas circulator 17, and molecular sieve column 20, surge tank 26, sodium-potassium bubbler 27 and filtrator 24, they are linked in sequence, and form a loop body.
Argon gas in the glove box 7 are by this system's deoxygenation and water, can make in the glove box 7 in the argons oxygen, liquid water content reduce to 1～3 μ L/L and 3～5 μ L/L respectively.
Link to each other with the gas circulation cleaning system by glove box 7, thereby avoided sodium sample contaminated, improved the accuracy of impurity analysis in the sodium, and do not cause the pollution of loop sodium.

Embodiment
Below in conjunction with accompanying drawing, this utility model is illustrated.
With sample crucible 2 transfer vessel 16 of packing into.At the following transfer vessel 16 of the inert atmosphere cask 12 of packing into, and then link to each other with glove box 7.Transfer vessel 16 is taken out in glove box 7 and installs to below the nickel flap 18.Driving sample hoisting gear 10 descends till compressing at primary seal 3 places screw rod 21.
Open into sodium mouth, allow loop sodium, get back in the sodium system of loop and go by going out sodium mouth and row's sodium mouth again through advancing continued to flow sample crucible 2 and be full of whole sampling container 1 of 4 holes on the sodium pipe 4.Remain on 0.22～0.29m at the sodium flow
3/ h, clean 2～4h after, making into, sodium pipe 4 and sample crucible 2 obtain cleaning.At this moment, the sodium that is retained in the sample crucible 2 can be thought representative sodium sample, drives sample hoisting gear 10, and sampling container 1 is risen to cooling section 5, adopts pressurized air that sodium sample is cooled to room temperature.Drive sample hoisting gear 10 once more, sampling container 1 is raised in the glove box 7, transfer vessel 16 is transferred in glove box 7 in the cask 12, this transfer process is carried out under inert environments.Argon gas in the glove box 7 is by molecular sieve column 20, surge tank 26, sodium-potassium bubbler 27, after the filtration of filtrator 24, oxygen, liquid water content are reduced to 1～3 μ L/L and 3～5 μ L/L respectively in the argon, make glove box 7 interior gases obtain continuous purification by gas circulator 17 again, guarantee in sampling in glove box 7, transfer and the weighing process that sample contamination amount reduces to minimum and constant.Guarantee the accuracy of impurity analysis in the sodium sample, made sodium sample not contaminated, also can not cause the pollution of loop sodium simultaneously.
