Problems solved by technology

The reason for the large building size of the irradiation station is that the maze for transporting items built to shield harmful rays takes up too much space. The width and height of the cross-section inside the maze are more than 1.5 meters, and the multiple turns of the maze also take up a lot of space. space, so that the length of the labyrinth is very long, and the scale of the building is very large

Embodiment approach 2

[0036] Such as image 3 The shown low-power mobile electron irradiation device includes an irradiated article transportation channel 3 , a shielding body 4 and an accelerator module 5 .

[0037] The accelerator module 5 includes an accelerating tube, a magnetron, a waveguide system, a vacuum system, etc., and other auxiliary systems such as a modulator and a water cooling unit are installed outside the shield 4 to reduce the volume and weight of the shield 4. The accelerating tube adopts a standing wave linear accelerating tube, and the output electron beam current parameter is 10MeV / 2kW. The accelerator module 5 is fixedly installed on the shielding body 4, and together with the shielding body 4, it is transported to different irradiation locations by a transport vehicle over a long distance.

[0038] The irradiated items are irradiated by the electron beam directly under the accelerator module 5 , are sent in through the entrance 1 of the transport channel, and are output t...

Abstract

The invention discloses a mobile electron irradiation device which comprises a shielding body, an irradiation article transportation channel and an accelerator module. The irradiation article transportation channel adopts a vertical turning motion structure; and the transmission device of the irradiated articles adopt double-chain vertical turning transmission or vertical turning segmented transmission. The device has the advantages that a vertical turning irradiation article transmission channel is provided, a split construction and installation mode of the accelerator module and the shielding body module of the electron irradiation accelerator device is provided, and double-chain transmission or vertical turning segmented transmission is adopted. The two innovations of vertical turning transmission and a split construction and installation mode greatly reduce the size, weight and construction cost of a shielding body of the accelerator, so that the movement of the 10MeV electron irradiation accelerator becomes possible, and meanwhile, the irradiation rate of an irradiated object can be improved. The double-chain transmission enables the circulating motion of the article box bearing the irradiated articles in the transmission channel to be possible.

Description

technical field [0001] The invention relates to an electron accelerator, in particular to a mobile electron irradiation device. Background technique [0002] Electron irradiation is a widely used processing technology, which can be used in food irradiation, medical supplies sterilization and irradiation chemical industry and other fields. Electron radiation processing is a special method that uses the physical, chemical and biological effects produced by the interaction between high-energy electrons and substances to change substances and form the desired properties of people. This technology can not only kill pathogenic bacteria on the surface of food, but also kill insects and pathogenic bacteria parasitic in the deep layer of food, prevent food spoilage and loss, realize storage and preservation of fruits and vegetables, inhibit germination, delay post-ripening, and prolong the preservation of fruits and vegetables It can even degrade the pesticide residues in agricultur...
