The working principle is as follows:
after the three electron beam emitters are arranged in the shielding chamber 1 in a surrounding manner, the box 4 conveyed by the transmission assembly can be uniformly irradiated and sterilized at three angles, so that in the structure, when the box 4 is transmitted to the respective radiation areas of the three electron beam generators by the transmission assembly, the electron beams emitted by the output ends of the three electron beam emitters irradiate from the box 4 in three directions, and due to the scattering of the electron beams, all the outer surfaces (including the upper surface, the lower surface, the left and right side wall surfaces and the front and rear wall surfaces) of the box 4 can be uniformly irradiated and sterilized.
The technical scheme has the advantages that:
the shielding chamber 1 for shielding the rays of the three electron beam emitters ensures that the irradiated rays cannot leak outwards and ensures the safety of operating personnel; the transmission assembly can be used for inputing box 4 to shielding room 1 in, can carry out sterilization treatment through the electron beam generator of three relative (just to or stagger) setting, high sterilization efficiency, no chemical residue, the operation is stable, and will export through sterilization treatment's box through the transmission assembly who advances in succession, it is higher to the exterior structure regularity (roughness) to make three electron beam generator through encircleing the overall arrangement, the higher box 4 of bottom roughness that introduces later on promptly, and box 4 upper portion has protruding edge (also can be called honeycomb box) carries out sterilization treatment, in order through the layout design to each structure, guarantee its and special application scene complex needs.
In another embodiment, three of the electron beam emitters are configured to employ an electron beam module defining an electron beam exit direction as a slanted exit window 6; the widths of the three exit windows are set to be larger than the width of the box.
(this structure is advantageous in that, by the structural limitation of the electron beam extraction window, the emission range of the electron beam is better controllable (with a certain opening angle for emission, forming fan-shaped emission) to match the height and width of the box 4. in practical operation, the width of the electron beam extraction window 6 is configured to be larger than the width of the box 4 (usually, the width of the box is larger than the height), which is effective in making the surfaces of the box 4 completely covered by the electron beam for radiation sterilization treatment; and at the same time, the length and space of the component in the shielding chamber 1 are saved, and the integration degree is higher.)
In another embodiment, the three electron beam emitters include an upper electron beam emitter 31 and two lower electron beam emitters 32; and deflection magnets 5 are respectively fixedly arranged in front of the output ends of the two lower electron beam emitters 32.
