Embodiment

[0024] see Figure 1 to Figure 3 , The electronic curtain accelerator shielding structure of this embodiment includes an upper shielding block 1 , a main shielding block 2 , a beam collector 21 , a rotating shaft 22 , a lower shielding block 3 and a shielding body 4 . The electron curtain accelerator shield structure is installed at the electron flow channel exit of the electron curtain accelerator. The electron curtain accelerator is provided with a titanium window 5, an electron curtain accelerator cathode 6 and a vacuum cavity 7. The titanium window 5 is arranged at the electron flow channel exit. The electron curtain accelerator The cathode 6 is a device for generating and accelerating the beam of the electron curtain accelerator, and the function of the vacuum chamber 7 is to prevent the filament in the cathode of the electron curtain accelerator from being oxidized and burned. The shielding body structure of this embodiment can effectively shield the radiation generated ...

Abstract

The invention discloses an electron curtain accelerator shield structure, and belongs to the technical field of industrial irradiation processing. The electron curtain accelerator shield structure comprises a shielding main body connected with an electron flow channel outlet of an electron curtain accelerator, and the shielding main body is movably connected with a main shielding block exactly facing the electron flow channel outlet, and an upper shielding block and a lower shielding block which are symmetrically distributed at the upper side and the lower side of the main shielding block. When the main shielding block, the upper shielding block and the lower shielding block move to a working position, the three shielding blocks and the shielding main body form a product channel for a product to pass through, and the product channel passes through the electron flow channel outlet. The shielding main body structure is fixed at the electron flow channel outlet of the electron curtain accelerator, and the main shielding block, the upper shielding block and the lower shielding block are moved to the working position, so that radiation generated by the electron curtain accelerator during ionization can be effectively shielded.

Description

technical field [0001] The invention relates to the technical field of industrial radiation processing, in particular to an electron curtain accelerator shielding structure. Background technique [0002] Electron accelerators use electrons to accelerate in a high-voltage environment to generate high-energy electron beams, and the electron beams are used to process and optimize the performance of the irradiated objects. Because the electron beam is radioactive, the technique falls under the category of nuclear technology. However, the electron beam technology is different from natural radionuclides. The electron beams generated mainly rely on the linkage of electric energy, which stops immediately when the power is turned off, and has better safety and controllability. Therefore, shielding is one of the most critical factors in the production and application of electron accelerators. A shielding device is provided for the X-rays generated by the accelerator, so that the X-ra...
