Abstract
The utility model discloses a jacket-type sample swager for radionuclide Gamma energy spectrum analysis. The jacket-type sample swager for the radionuclide Gamma energy spectrum analysis comprises a base and a compression rod capable of being inserted into an inner jacket so as to compress a sample; the base is provided with an outer jacket; and the inner jacket is sleeved in the outer jacket, and is formed by symmetrically arranged two semi-circular rings. According to the jacket-type sample swager, the inner jacket and the outer jacket which are separated are used, and the outer jacket and the compression rod can be matched with a plurality of pairs of inner jackets; and the inner jacket is designed detachably, so that the compressed sample is easy to be separated from the inner jacket, and the inner jacket designed in separation is also easy to clean. Additionally, after the jacket-type sample swager for the radionuclide Gamma energy spectrum analysis, provided by the utility model, is used, the sample preparation efficiency and the uniformity of the radionuclide Gamma energy spectrum analysis can be improved obviously, and the accuracy of a measurement result is improved.
Description
Technical field
The utility model relates to a kind of radioactive nuclide gamma spectrum analysis with jacket type sample swager, is a kind of die arrangement that is used for processing solid kind food or environmental sample reflectivity nucleic gamma spectrum sample for analysis.
Background technology
The gamma spectrum analysis of radioactive nuclide mainly realizes by gamma energy spectrometer in food or the environmental sample.Gamma energy spectrometer is made up of detector, pulse height analyzer, record display circuit three parts, during work, detector becomes the ray of different-energy into the electric pulse of corresponding amplitude and is amplified, and deliver to that pulse height analyzer is separated and record, it both can measure gamma spectrum, can measure total gamma-radiation dose rate again.Before the use gamma energy spectrometer was measured, sample need be through suitable processing to make the analysis sample, and for the high sample of water percentage, general first drying is pulverized or the high temperature ashing then, Malin's cup the inside of the specific standard of packing into then; And for the low sample of water percentage, can directly pulverize or ashing, refill in cup.In addition, in order to improve the sensitivity of test, analytic sample in Malin's cup needs suitable compacting, but, because the material of Malin's cup is generally tygon and polypropylene, so its physical strength is relatively poor, like this, will cause the decrement of sample low relatively poor, increase the error of measuring with compaction's homogeneity.
Summary of the invention
For addressing the above problem, it is a kind of simple in structure, easy to use that the utility model provides, and can improve the radioactive nuclide gamma spectrum analysis jacket type sample swager of measurement result.
The utility model is that the technical scheme that its problem of solution is adopted is:
A kind of radioactive nuclide gamma spectrum analysis comprises base with jacket type sample swager, and described base is provided with external jacket, is arranged with interior chuck in the described external jacket, and described interior chuck is two symmetrically arranged semicircular ring; Also comprise and to insert interior chuck to compress the depression bar of sample.
Preferably, be provided with outage bottom the described interior chuck; The outage of interior chuck bottom possesses the function of discharge opeing and exhaust, helps the compacting of sample.
Preferably, described depression bar is provided with scale mark; Depression bar is provided with scale mark on certain location, the degree of convenient control compacting improves the homogeneity that is pressed into product density.
Preferably, described base is provided with the handle ring, and personnel move mould with handled easily.
The beneficial effects of the utility model are: use inside and outside two-layer chuck separately, external jacket and depression bar can join many secondary in chucks; Interior chuck adopts detachable design, and the compacting sample is separated with interior chuck easily, and separately the interior chuck of design also is easier to clean.In addition, can obviously improve radioactive nuclide gamma spectrum analytic sample sample preparation efficient and homogeneity after having used the utility model, improve the precision of measurement result.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Embodiment
A kind of radioactive nuclide gamma spectrum analysis shown in accompanying drawing 1, accompanying drawing 2 jacket type sample swager, comprise base 1, described base 1 is provided with external jacket 2, chuck 3 in being arranged with in the described external jacket 2, and interior chuck 3 can be made by SUS316 stainless steel or S136H mould steel.External jacket 2 is combined closely with interior chuck 3, be mainly used in to bear sample when compacted, the pressure that interior chuck 3 expands outwardly, preferably, described in chuck 3 be two symmetrically arranged semicircular ring.Interior chuck 3 inside are inserted with depression bar 4, and to compress sample, the upper surface of the lower surface of depression bar 4 and base 1 all carries out polishing, prevents that sample from sticking on the mould.
The utility model uses inside and outside two-layer chuck separately, with the different sample of reply processing, external jacket 2 and depression bar 4 can join many secondary in chucks 3.Interior chuck 3 adopts detachable design, and the compacting sample is separated with interior chuck 3 easily, and chuck 3 is easier to clean in also making.In addition, used the utility model processed sample after, can obviously improve radioactive nuclide gamma spectrum analytic sample sample preparation efficient and homogeneity, improve the precision of measurement result.
Chuck 3 lower ends are apart from the bottom 5mm place outage 5 that evenly to be provided with four diameters be 2mm in described; Outage 5 possesses the function of discharge opeing and exhaust, helps the compacting of sample.Described depression bar 4 is provided with scale mark 6, depression bar 4 is provided with scale mark 6 on certain location, the degree of convenient control compacting, improve the homogeneity of finished product density, in addition, operating personnel can adopt suitable method such as weighing to guarantee that sample size is identical when each compacting sample, make the degree of each sample compacting suitable, obtain the good specimen of density uniformity.Described base 1 is provided with handle ring 7, and personnel move mould with handled easily.
During use, operating personnel interior chuck 3 synthetic tubuloses, are placed on the base 1 earlier, and chuck 3 just entangles platform outstanding on the base 1 in making; Then external jacket 2 is enclosed within outside the interior chuck 3, and inwardly adds a certain amount of sample in the chuck 3.Operating personnel put into depression bar 4 from the top of interior chuck 3 again, compress in advance earlier with hand, arrest handle ring 7 on the mold base 1 with hand then, mould put into range be 5～10 tons manually or automatic tableting presses, actual conditions are per sample selected suitable pressure compacting; Take out mould after the pressure release, extract depression bar 4 and external jacket 2, the specimen that chuck 3 can obtain suppressing in separating with hand.
Above instructions is described, only is principle of the present utility model and embodiment, everyly carries out any simple modification and variation according to essence of the present utility model, all belongs within the desired protection domain of the utility model.
