Description
Technical field
The utility model belongs to nuclear chemical industry fuel analysis detection technique field, and in particular to one kind is used for MOX pellet densities
The infiltration apparatus of measurement.
Background technology
MOX pellet densities are one of product important indicators, and quick, accurate measurement pellet density is that detection device need to reach
Important indicator.The density measure mode of traditional fuel pellet is by after pellet immersion in a liquid a period of time, detects it respectively
Calculated after liquid weight, buoyant weight, dry weight and obtain density value.MOX pellets and the structure of traditional fuel pellet have larger difference, MOX cores
Block size is smaller, has centre bore, and to ensure the security during heap use, passed through in MOX pellet manufacturing processes
Process makes tiny hole, and due to said structure feature, traditional general pattern of invasion can not ensure that immersion fluid is abundant
Centre bore and surface pores are filled up, effect of impregnation is bad, causes the not high of measuring accuracy.
The content of the invention
The purpose of this utility model is to provide a kind of safe efficient, reliable infiltration for the measurement of MOX pellet densities
Device, to overcome the shortcomings of the prior art.
To reach above-mentioned purpose, technical solution adopted in the utility model is：
A kind of infiltration apparatus for the measurement of MOX pellet densities, including vacuum tank, container cover, imbibition pipeline quick-joint valve
Door, vacuum lead quick-connecting valve, vacuum pump, solution bottle and pressure gauge；Container cover is provided with vacuum tank, is divided in container cover
Pump-line and imbibition pipeline are not connected with, and pressure gauge and vacuum lead quick-connecting valve are provided with pump-line；Pipette
Imbibition pipeline quick-connecting valve is provided with road, imbibition pipeline gos deep into solution bottle bottom surface, and liquid absorption amount is calculated by scale and pressure gauge；
Vacuum pump is positioned over outside glove box, is connected with pump-line.
The vacuum tank is cup-shaped, and there is dismountable screen work in inside, for placing the MOX pellets of different numberings.
The vacuum tank is fixed with container cover by butterfly clip.
Elastic seal ring is provided between the vacuum tank and container cover.
The solution bottle is transparent glass container with a scale.
Having the beneficial effect that acquired by the utility model：
The utility model can make immersion fluid adequately fill up the centre bore and surface pores of MOX pellets, have preferable leaching
Moisten effect, the measurement accuracy of MOX pellet densities can be significantly improved.

Container cover 2 is provided with 1, vacuum tank 1 is fixed by butterfly clip 3 with container cover 2, set between vacuum tank 1 and container cover 2
It is equipped with elastic seal ring 6.Pump-line and imbibition pipeline are connected in container cover 2, pressure gauge is provided with pump-line
9th, vacuum lead quick-connecting valve 5；Imbibition pipeline quick-connecting valve 4 is provided with imbibition pipeline.Solution bottle 8 is with a scale saturating for one
Bright glass container, imbibition pipeline go deep into 8 bottom surface of solution bottle, and liquid absorption amount is calculated by scale and pressure gauge 9.Vacuum pump 7 is positioned over
Outside glove box, it is connected with pump-line.
MOX pellets are put into vacuum tank 1, vacuum lead quick-connecting valve 5 is opened, and imbibition pipeline quick-connecting valve 4 closes
Close, start vacuum pump 7 and start to vacuumize.After vacuumizing, vacuum lead quick-connecting valve 5 is closed, after pressurize for a period of time, it is ensured that
Residual gas in MOX pellets centre bore and surface pores is sufficiently removed.Imbibition pipeline quick-connecting valve 4 is opened, in solution bottle 8
Liquid into vacuum tank 1, makes immersion fluid adequately fill up the centre bore and surface pores of MOX pellets due to vacuum action.
