Material operation, so as to realize the safety loading of irradiated fuel assembly.
And in above loading and unloading operating process, water-filling and circulating cooling can be carried out to spent fuel transport container.From spentnuclear fuel
The water of shipping container backflow needs to enter the impurity in water using filter before entering spentnuclear fuel transport processing Multifunctional bench
Row filtering, to prevent the conduit failure component for blocking spentnuclear fuel transport processing Multifunctional bench, while reducing radioactivity as far as possible
Impurity enters stand.The impurity that filter is filtered out often has higher radioactivity so that periphery staff is in higher
Radioactive environment under.
The content of the invention
The utility model provides a kind of radiation shield filter suitable for spentnuclear fuel hauling operation, for filtering weary combustion
The water flowed back during material hauling operation from spentnuclear fuel transfer container, can not only improve filter efficiency, additionally it is possible to which shielding comes
From the radioactivity of filter residue, reduce its irradiation intensity to environment.
The technical solution of the utility model is：
A kind of radiation shield and filter suitable for spentnuclear fuel hauling operation, including filter body, filter core, filter core
Lid, screen layer, screen layer include filter body screen layer and filter core lid screen layer；
Filter body is three-port structure, and a port is that fluid intake, a port are fluid issuing, a port peace
Filter core is filled, is straight line main road between fluid inlet end and fluid outlet, has between branch road and main road and filter is installed in angle, branch road
Core；
Tributary port is connected with filter core lid, and filter core is fixed in filter body；Filter body main road inwall is corresponding
Filter core top is blocked in position provided with projection, spacing to filter core progress, and filter core separates fluid issuing and fluid intake；
Filter body screen layer includes two parts of radial symmetric, is fastened by bolts in filter body periphery,
It is brought into close contact with filter body；Filter core lid is coated on inner side by filter core lid screen layer.
The filter core lid and filter core are fabricated to integral structure.
The filter core lid and filter core are demountable structure.
The filter core lid screen layer is fabricated to integral structure with filter core lid.
The filter core lid screen layer is demountable structure with filter core lid.
The filter body screen layer and filter core lid screen layer are made up of lead matter inner core and steel casing.
Filter body and the filter core lid is made up of stainless steel material.
The beneficial effects of the utility model are：
First, the utility model, can be effective while the water flowed back to spentnuclear fuel transfer container carries out high efficiency filter
Radioactivity of the fruit shielding from filter residue, reduces its irradiation intensity to environment, reduces personnel's radioactive dose.
Second, the utility model easily can dismantle and change filter core, during filter element replacing, without removing filtering
Device main shield layer, you can realize the replacing of filter core, so as to reduce the dismounting of screen layer, reduces the exposure of radioactive element.
3rd, the utility model is compared to the lead-sheathing skin used, private mask layer and the filter of its filter temporarily
Stickiness more preferably, close to seamless connection, can greatly shield the radioactivity from filter.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1- filter bodies, 2- filter body screen layers, 3- filter cores, 4- filter core lids, 5- filter core lid screen layers.
Embodiment
The utility model is described further with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model is a kind of radiation shield and filter suitable for spentnuclear fuel hauling operation, should
For being filtered in spentnuclear fuel transport process to the water that spentnuclear fuel transfer container flows back, including filter body 1, filter core 3, filter
Core cap 4, screen layer, screen layer include filter body screen layer 2 and filter core lid screen layer 5.
Filter body 1 is overall to be similar to three-port structure, constitutes fluid passage, and a port is fluid intake, an end
Mouth is fluid issuing, a port installs filter core 3, is straight line main road, branch road and master between fluid inlet end and fluid outlet
Have between road and filter core 3 is installed in certain angle, branch road；Tributary port is connected with filter core lid 4, and filter core 3 is fixed on into filter master
In body 1；The top of filter core 3 is blocked in the main road inwall relevant position of filter body 1 provided with projection, filter core 3 is carried out it is spacing, meanwhile,
So that filter core 3 separates fluid issuing and fluid intake, so as to realize filtering function.
The effect of filter core 3 is filtering fluid, and when fluid flows through filter described in the utility model, impurity is filtered out by filter core 3,
Under gravity, it is deposited on filter bottom；Such structure can reduce it by residue collection to filter bottom
