Embodiment Construction

[0009] Referring to the accompanying drawings, the present invention includes an accelerating tube 1 , a drift tube 3 , a scanning electromagnet 5 and a scanning box 7 with a built-in ion pump 6 . The acceleration tube 1 adopts a standing wave acceleration structure with an exhaust port 11 that requires a high degree of vacuum. The scanning electromagnet 5 is placed around the top of the scanning box 7 and is connected with the drift tube 3 through the second flange 4 . The bottom of the scanning box 7 is fastened with the lead-out window 9 made of titanium foil material through the flange plate 3 10 . The upper end of the drift tube 3 is connected to the acceleration tube 1 through the flange one 2 . The flange one 2 between the acceleration tube 1 and the drift tube 3 is connected by welding with a thin-edged flange. The flange plate 2 4 between the drift tube 3 and the scanning box 7 is connected by welding with a thin-edged flange to ensure very high airtightness. The s...

Abstract

An acceleration and scanning integrated structure of fully impervious high vacuum electron beam belongs to the fields of radiation processing technology. It includes accelerating tube, drift tube, scanning electromagnet and scanning box equipped with ion pump, the scanning electromagnet is mounted on top of the scanning box and is connected with the drift tube by the ring flange two, and the top end of the drift tube is connected with the accelerating tube by the ring flange one. It characterized in that the accelerating tube and the scanning box are located and fixed by bracket, the ring flange two and the ring flange one are connected with each other by welding mode with featheredge flange, the accelerating tube adopts the standing wave acceleration structure equipped with exhaust orifice. Compared with current technology, the invention improves the stability and tightness of the accelerator and makes whole volume smaller; it can discharge air in high-temperature discharging furnace directly and leave out the endless vacuum exhaust cause of accelerating tube. It possesses engineering practicability.

Description

technical field [0001] The invention relates to the technical field of radiation processing, in particular to an irradiation device using an electron beam accelerator as a radiation source. Background technique [0002] Electron beam irradiation technology is to use the accelerator to generate a certain energy (1MeV ~ 20MeV) electron beam to produce biological and physical effects on different items, so as to achieve the purpose of modifying or disinfecting the items. In recent years, electron beam irradiation technology has developed vigorously in the fields of industrial processing, disinfection and sterilization, insecticide, and fresh-keeping. Generally, accelerators are used to generate electron beams with a certain energy, which are drawn out by titanium windows. These accelerators include: traveling wave or standing wave electron linear accelerators, DC high-voltage accelerators, high-frequency high-voltage accelerators, etc. The irradiated article is passed through ...
