Beam shielding device for industrial electron accelerator

Abstract

The invention discloses a beam shielding device for an industrial electron accelerator and relates to the industrial electronic accelerator technology. The beam shielding device for the industrial electron accelerator is characterized by comprising twelve parts such as a main body bracket, a stroke base, a stroke guide rod, a stroke transmission rod, a water absorber mounting seat, a water absorber, a motor box, a stroke cable and a control box, wherein the stroke base is fixed with an upper edge of the main body bracket, the water absorber mounting seat penetrates through the stroke guide rod and the stroke transmission rod through a sliding sleeve and a wire sleeve structure, the stroke transmission rod is driven by a motor through a coupling to rotate to make the water absorber move, the stroke information of the water absorber is transmitted by the stroke cable to a stroke switch, and the water absorber is made to reliably move and position. The beam shielding device is advantaged in that the motor can be shielded, electrical components can be mounted at the position with a small electron beam radiation dose radiation dose, the service life of devices is significantly prolonged, a beam blocking device can be easily turned to the far place, and the sufficient maintenance space is reserved.

Description

technical field [0001] The invention relates to industrial electron accelerator technology, in particular to electron beam current shielding technology. Background technique [0002] The industrial electron accelerator is used to irradiate the goods. It emits an electron beam through the scanning box to scan the moving goods on the conveying line, so that the goods can obtain a predetermined radiation dose. If the conveying line stops due to a sudden failure, or if the goods are jammed due to the shape and displacement of the goods, the goods will be over-irradiated, damaged, heated or even burned, which will pose a great safety risk; moreover, changing the radiation dose of the goods, In the working links such as debugging the beam quality, the electron beam will cause certain damage to the conveyor line without cargo obstruction. Therefore, beam blocking shielding is required in these links. [0003] Existing beam blocking devices, such as Patent No. CN201710439026.X "a ...

Problems solved by technology

[0003] Existing beam blocking devices, such as Patent No. CN201710439026.X "a beam baffle device for swing-type accelerator", use power parts such as solenoid valves and cylinders, and do not shield the power parts; another example is patent CN201220656703.6 "Industrial electron accelerator mobile beam baffle device" uses cylinders to drive connecting rods and rockers to move, and does not shield the cylinders; the first shortcoming of the prior art is that in high radiation and ozone environments, Without effective shielding, the operating stability of cylinders, solenoid valves and other components will be reduced, and the life will be shortened; the second disadvantage is that the cost of the air compressor, the difficulty of installation, and the frequency of failure are increased; the third defect is that the device installation On the side immediately adjacent to the scan box, impeding equipment servicing
