Problems solved by technology

This form requires the construction of shielded buildings and the use of transmission devices, so it is difficult to miniaturize the device
At the same time, there are openings on the shielding wall for the transmission device to pass through, which destroys the integrity of the shielding structure, increases the difficulty of radiation protection, complicates the device, and increases the equipment cost

Embodiment 1

[0015] see figure 2 , the present invention includes an electron beam radiator 1 and an integrated shielding body 2 composed of electron accelerators, drift tubes, titanium windows and other components. The electron beam radiator 1 is installed on the top center of the integrated shield 2, and the side wall of the integrated shield 2 is installed with a closed protective door 5 that can deliver and retrieve items, and the integrated shield 2 is equipped with a tray that can support the items 3. The tray 3 is supported by a support rod 6 connected to its bottom plane, and the support rod 6 extends hermetically beyond the bottom plane of the integrated shield 2 and is connected to the transmission mechanism 7 . The transmission mechanism 7 adopts the transmission form of double bevel gears driven by the motor. A cooling liquid 4 is placed at the bottom of the integrated shielding body 2 . Of course, if the transmission form in which the motor drives the worm screw and the wo...

Embodiment 2

[0022] see image 3 , the present invention includes an electron beam radiator 1 and an integrated shielding body 2 composed of electron accelerators, drift tubes, water-cooled double-layer titanium windows and other components. The electron beam radiator 1 is installed on the top center of the integrated shield 2, and the side wall of the integrated shield 2 is installed with a closed protective door 5 that can deliver and retrieve items, and the integrated shield 2 is equipped with a tray that can support the items 3. The tray 3 is supported by a support rod 6 connected to its bottom plane, and the support rod 6 is fixed at the inner center of the bottom of the integrated shielding body 2 . A cooling liquid 4 is placed at the bottom of the integrated shielding body 2 . The water-cooled double-layer titanium window is set above the longitudinal linear gradient electric field or magnetic field. The water-cooled double-layer titanium window adopts water cooling in the middle...

Abstract

A shielded electronic beam irradiation sterilizer is composed of an electronic beam irradiator consisting of electronic accelerator, shifting tube and Ti window, and an integrated shielding body with a sealed protecting gate for transferring article, a tray with supporting rod, drive unit and cooling liquid.

Description

technical field [0001] The invention relates to the application field of nuclear technology, in particular to a shielded electron beam irradiation sterilization device. Background technique [0002] Electron beam irradiation sterilization technology is a treatment technology that uses the ionization ability and bremsstrahlung effect of electron beams to cause certain biological and physical effects on irradiated items, thereby performing sterilization and deworming or changing the physical properties of the items. The use of electron beams produced by electron accelerators to sterilize mail or small items is an important technology related to safety and anti-terrorism. In the prior art, the devices used to sterilize mail or small items are as figure 1 As shown, it is an electron beam (beta ray) with a certain energy generated by an electron accelerator, which makes the ray do a transverse scanning motion under the action of a transverse alternating electric field or magneti...
