Detailed description of the invention
It is the structural representation of one specific embodiment of this utility model referring to figs. 1 through Fig. 3, Fig. 1 to Fig. 3, as it can be seen,
A kind of bridge-type radioprotective self-shileding transfer passage for electronic beam curing, including including radiation channel 1, feeding-passage 2 and going out
Material passage 3, described radiation channel 1 is provided with electron beam launcher 4, and described radiation channel 1 is provided with covering radiation channel 1
And the shielding case 5 of electron beam launcher 4, described radiation channel 1 is higher than feeding-passage 2 and tapping channel 3, described radiation channel
1 two ends are connected to feeding-passage 2, tapping channel 3 by oblique charging interface channel 11, oblique discharging interface channel 12 respectively,
Described shielding case 5 two ends extend to cover oblique charging interface channel 11 and oblique discharging interface channel 12.
Preferably, described electron beam launcher 4 is an electron accelerator, the preferred 80kV of this electron accelerator high pressure ~
300kV, the strong preferably 20mA ~ 500mA of stream, the optional lead of radiation shielding material, iron and steel, concrete, wherein preferred lead, the thickness of sheet lead
1.5cm ~ 2.5cm, i.e. can reach the effect of shielding protection.
During work, the electronics that electron beam launcher 4 is launched is beaten bottom processed sheet material and shielding case 5, has portion
Bremstrahlen is divided to produce.For the electron beam of 80keV ~ 300keV, the bremstrahlen overwhelming majority that it produces will be along electricity
90 degree of directions transmittings (bremstrahlen overwhelming majority edge produced by the electron beam that i.e. electron beam launcher is launched that son bundle is incident
Radiation channel plane to launch), by oblique charging interface channel 11 and oblique discharging interface channel 12 and cover to the two it
On shielding case 5, it is possible to effective reduce the radiation revealed from charging aperture, discharging opening so that radiation value (the radiation agent leaked
Amount) less than level of protection value, it is prevented effectively from and human body is damaged.
In this utility model, described oblique charging interface channel 11 and oblique discharging interface channel 12 can be oblique directly
Passage or oblique curved channel, it is preferred that in the present embodiment, use oblique straight channel, and by oblique charging interface channel 11
It is 5 °-10 ° with the inclination angle of oblique discharging interface channel 12, now can be good at ensureing the uniform of coating on flat-type workpiece
Property, it is to avoid uneven after flat-type workpiece paint solidification, leak meanwhile, it is capable to reduce radiation, additionally, at this utility model
In, radiation channel 1, feeding-passage 2 and tapping channel 3 are horizontally disposed, can be by extending the length of radiation channel 1 so that workpiece
Before below the electron beam launcher 4 entering radiation channel 1, there is longer one end level transportation section, further ensure
The uniformity of the coating on flat-type workpiece.
As it can be seen, described shielding case 5 end is and feeding-passage 2, opening that tapping channel 3 is corresponding, in described opening
Portion's peak, less than the minimum point within shielding case 5 of radiation channel 1, can realize radiation shield, preferably this open height D
It is preferably 150mm-300mm, coordinates the inclination angle of 5 °-10 °, it is ensured that the normal conveying of workpiece, can effectively reduce radiation simultaneously
Leak.
Certainly, in specific implementation process, open height also can be set to more greatly or more by the workpiece for other shapes
Little, in the case of ensureing transportation performance, inclination angle may also be configured to bigger so that the effect of shielding is more preferable.
As shown in the figure, it is preferred that described shielding case 5 two ends extend out to part and cover feeding-passage 2, tapping channel 3,
Further enhance the effect of shielding.
Preferably, if described radiation channel 1, feeding-passage 2 and tapping channel 3 are to include that the conveying continuously of dry drum 92 is logical
Road, described cylinder 92 can arrange corresponding device of rotation driving, to drive workpiece to move along transfer passage, forms continuous print raw
Runoff yield waterline.
This utility model, by radiation channel 1 is set above feeding-passage 2 and tapping channel 3, forms the defeated of bridge-type
Sending passage and shielding case 5 structure, owing to the length direction along radiation channel that radiates of electron beam launcher extends, two ends are downward
The shielding case 5 tilted can effectively block radiation, thus reduces amount of radiation, meanwhile, and radiation channel 1, feeding-passage 2 and discharging
Passage 3 conveying direction is a straight line, can reduce the space that transfer passage laterally takies, more convenient transfer passage and production flowing water
The docking of line.
Above preferable enforcement of the present utility model is illustrated, certainly, this utility model can also use with
The form that above-mentioned embodiment is different, those of ordinary skill in the art made on the premise of spirit of the present invention etc.
With conversion or change accordingly, all should belong in protection domain of the present utility model.
