Technical field
The utility model patent belongs to analysis of Uniformity device field, and in particular to a kind of MOX granulated pellets uniformity point
Analysis apparatus.
Background technology
Mox fuel factory is the intermediate link between reprocessing plant and presurized water reactor and fast reactor, is to realize that China's nuclear fuel is closed
The key link of cycle.For MOX mixed-powders after granulation, ball milling, the uniformity of particle is one of technical target of the product requirement,
The quality of product will be directly affected.Conventional method manually carries out screening operation by sampling to powder, calculates different grain size distribution
Quality.Due to the high Radiation Characteristics of raw material, conventional method needs operating personnel frequently to operate, and manual separation is improved and irradiated
Risk, and operated in glove box and necessarily will increase operation difficulty, especially in the case where sampling amount is especially small.Therefore, it needs
A kind of fast and efficiently granulated pellet analysis of Uniformity device, solves the problems, such as that operating difficulties, irradiation dose are big.
Invention content
The purpose of the present invention is to provide a set of MOX granulated pellet analysis of Uniformity devices quickly, practical, realize sample
Uniformity quickly, is reliably analyzed, and the irradiated risk of operating personnel is solved.
Technical scheme is as follows：A kind of MOX granulated pellets analysis of Uniformity device, screw feed mechanism are located at whole
A device the top, vertical structure, by helical blade rotation and gravity, make material slowly, uniformly fall into screening mechanism
Interior, screw feed mechanism top is equipped with material and keeps in container, is V-structure, and carries sealing cover；Below screw feed mechanism
Low mesh number molecular sieve is connected, high mesh number molecular sieve is connected below low mesh number molecular sieve, high mesh number molecular sieve reconnects bottom splicing
Container, splicing lower vessel portion in bottom connects one-eccentric rotor type vibrator, and one-eccentric rotor type vibrator is located on pressure lifting device, pressure lifting
Device provides pressure in screening process, ensures the connection of entire mechanism；And one-eccentric rotor type vibrator makes screening mechanism do plane vibration,
Make powder realize by molecular sieve by vibration to detach.
The screw feed mechanism uses leaded stainless steel material, thickness 5mm or more.
It is connected through a screw thread low mesh number molecular sieve below the screw feed mechanism.
It is connected through a screw thread high mesh number molecular sieve below the low mesh number molecular sieve, high mesh number molecular sieve is connected by screw thread again
Connect bottom splicing container.
It is described in the junction of screw feed mechanism and low mesh number molecular sieve, low mesh number molecular sieve and high mesh number molecular sieve
Junction and the junction of high mesh number molecular sieve and bottom splicing container are equipped with metal o-ring, ensure sealing effect.
The remarkable result of the present invention is：Quickly, efficiently, reliably, the deficiency of conventional apparatus is solved.

Specific implementation mode
A kind of MOX granulated pellets analysis of Uniformity device, screw feed mechanism 1 are located at whole device the top, vertical to tie
Structure, by helical blade rotation and gravity, make material slowly, uniformly fall into screening mechanism, avoid material because of primary mistake
Mostly screening effect is reduced into screening structure.1 top of screw feed mechanism is equipped with material and keeps in container 8, is V-structure,
And sealing cover 9 is carried, it avoids frequently toppling over dust from flying caused by material.To reduce irradiation level, 1 shell of screw feed mechanism
It is all made of leaded stainless steel material, thickness 5mm or more.
1 lower section of screw feed mechanism is connected through a screw thread low mesh number molecular sieve 2,2 lower section of low mesh number molecular sieve passes through screw thread
High mesh number molecular sieve 3 is connected, high mesh number molecular sieve 3 is connected through a screw thread bottom splicing container 7 again, and in screw feed mechanism 1
With the junction of low mesh number molecular sieve 2, junction and high mesh number molecular sieve 3 of the low mesh number molecular sieve 2 with high mesh number molecular sieve 3
It is equipped with metal o-ring 6 with the junction of bottom splicing container 7, ensures sealing effect.
7 lower part of bottom splicing container connects one-eccentric rotor type vibrator 4, and one-eccentric rotor type vibrator 4 is located on pressure lifting device 5,
Pressure lifting device 5 provides pressure in screening process, ensures the connection of entire mechanism.And one-eccentric rotor type vibrator 4 makes screening mechanism
Plane vibration is done, so that powder is realized by molecular sieve by vibration and detaches.
