The present invention covers rubberized cord irradiation with self-shileding beam the characteristics of device and advantage is：
1st, it is symmetrical in present invention two side walls (i.e. left side wall 10 and right side wall 12) opposite in shield 9 to set two
A barricade (i.e. left barricade 4 and right barricade 18) and in being set on the bottom wall 22 of shield 9 between two barricades
Supporting rack 16, shield 9 is divided into basic cave 8 above by supporting rack 16 and two barricades and is located at
The lower section of basic cave 8 and the left redundant screened room 3 and right redundant screened room 19 that are symmetrical set, had both met wanting for shielding properties
Ask, and carried out cleverly spatial design, take full advantage of space in shield 9, saved in the transmission direction of product
Space, makes occupation of land of the shielding harness in the transmission direction of product shorten to 1.2 meters or so by existing 2.0 meters, compact-sized,
Floor space and volume are reduced, greatly reduces the consumptive material of shielding harness.
2nd, the present invention by set on the left side wall 10 of shield 9 outer entrance 2, setting outer vent 20 on right side wall 12,
Entrance 5 and inner outlet 17 in being set respectively between supporting rack 16 and left barricade 4 and right barricade 18, make to cover rubberized cord 1 more
Under the guiding of a guide roller 6, enter successively through outer entrance 2 in left redundant screened room 3, enter through interior entrance 5 in basic cave 8,
Enter through inner outlet 17 in right redundant screened room 19, be pierced by right redundant screened room 19 through outer vent 20, realize in basic cave 8
Irradiated to covering rubberized cord 1, while floor space can be reduced, reduce spillage of material and the weight of shielding harness.
It is 3rd, of the invention by setting electron accelerator in the roof 11 of shield 9, absorbing target 15 being set on supporting rack 16,
And make the scanning window 13 of electron accelerator and absorbing target opposite about 15, so that the scanning window 13 of electron accelerator is to covering rubberized cord
1 irradiated after ray absorbed by absorbing target 15；Beam flow baffle plate 14 is set in basic cave 8 at the same time, with without irradiation
When, the scanning window 13 that electronics accelerates is isolated with covering rubberized cord 1 by beam flow baffle plate 14；And by being set in basic cave 8
Air cooling mechanism 7, realizes the cooling of the outlet of scanning window 13 to electron accelerator, and by beam flow baffle plate 14 and absorbing target
Recirculated cooling water is passed through in 15, realizes cooling down.
The above is only presently preferred embodiments of the present invention, and limitation in any form is not done to the present invention, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, has in any technical field
Usual skill, in the range of technical solution of the present invention is not departed from, when the technology contents using the disclosure above make it is a little
The equivalent embodiment of equivalent variations is changed or is modified to, as long as being the content without departing from technical solution of the present invention, according to the present invention
Any simple modification, equivalent change and modification for being made to above example of technical spirit, still fall within the technology of the present invention side
In the range of case.
