Fig. 1-5 show an implementation form of the present invention, including:

a shielding chamber 1, between an inlet end 101 and an outlet end 102 of which a transport assembly for moving the cassettes 4 to be sterilized is arranged; electron beam emitters 3 which are laterally distributed at the left and the right are respectively arranged in the shielding chamber 1; the electron beams emitted by the two electron beam emitters 3 irradiate and sterilize the outer surface of the box 4 from the left side and the right side of the box 4.

The working principle is as follows:

after the two electron beam emitters 3 are oppositely arranged at the left side and the right side in the inner space of the shielding chamber 1, the box 4 which is conveyed can be irradiated and sterilized at the left side and the right side on the outer surface of the box, in the structure, the two electron beam generators 3 are correspondingly arranged at the left side and the right side in the space, one electron beam is emitted rightwards, the other electron beam is emitted leftwards, when the box 4 is transmitted between the two electron beam generators 3 through the transmission assembly, and when the left surface and the right surface of the box 4 pass through the left electron beam emitter and the right electron beam emitter 3, all the outer surfaces (including the upper surface, the lower surface, the left side wall surface, the right side wall surface and the front wall surface and the rear wall surface) of the box 4 can be irradiated and sterilized at the same time due to the scattering of the electron beams.

The technical scheme has the advantages that:

the shielding chamber 2 for shielding the electron beam emitter 3 by rays ensures that the rays cannot leak outwards and ensures the safety of operating personnel; the transmission assembly can be used for inputting box 4 to shielding room 1 in, can carry out sterilization treatment through controlling relative (just to or stagger) electron beam generator 3 that sets up, high sterilization efficiency, no chemical residue, the operation is stable, and will export through sterilization treatment's box 4 through the transmission assembly who advances in succession, it is higher to the outside structure regularity (roughness) to make two electron beam generators 3 through controlling relative 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, with through the overall arrangement design to each structure, simplify equipment, reduce the area of equipment simultaneously, guarantee its and special application scene complex needs.

In another embodiment, two of the electron beam emitters 3 are configured to employ an electron beam module defining an electron beam exit direction as a vertical exit window 5; the height of both of said exit windows is set to be greater than the height of the box 4.

(this structure is advantageous in that the emission range of electron beams is more controllable by the structural definition of the electron beam extraction window 5 to match the height of the housing 4. in practice, the height of the window of the vertical extraction window 5 is configured to be greater than the height of the housing 4, which is effective in sterilizing the upper and lower surfaces of the housing 4 by the electron beams exceeding the height of the side surface of the housing 4.)

In another embodiment, the output ends of the two electron beam emitters 3 are arranged right and left.

(the structure has the advantage that the structure greatly saves the installation space of the two electron beam emitters 3 in the shielding chamber 1 by arranging the output ends of the electron beam emitters 3 to be opposite to each other, and achieves the purpose of saving space under the condition of ensuring the uniform sterilization effect on all sides of the box 4.)

In another embodiment, the output ends of the two electron beam emitters 3 are arranged offset to the left and right.

(the configuration is advantageous in that the electron beams emitted from the left and right electron beam emitters do not irradiate each other by arranging the output ends of the electron beam emitters 3 in a staggered manner, a front left electron beam emitter 31, and a rear right electron beam emitter 32. this arrangement is advantageous in that the service life can be extended.)

In another embodiment, the inlet end and the outlet end of the shielding chamber 1 are respectively provided with a shielding door group 11; two shielding doors are respectively arranged inside each shielding door group 11.

(this configuration is advantageous in that the shield doors 11 can be opened and closed according to the current transfer position of the cassette 4 on the transmission line to ensure that at least one of the shield doors in each of the shield door groups 11 is in a completely closed state at any time, thereby preventing the radiation leakage from the shield room 1 in operation in any state)

In another embodiment, the transfer assembly may be configured as a plurality of rotating rollers 21 arranged at the bottom of the cassette 4 for coordinated transfer.

(the advantage of this structure is, in the practical application, to the higher bottom flatness box 4, can adopt in the box bottom set up the rotation roller 21 way carry on transmission.)

In another embodiment, the transport assembly may be configured as a hanging roller 22 positioned at an upper protruding edge of the cassette 4 for cooperative transport.

(the advantage of this structure is that for the box 4 with a protruding edge on the top, the protruding edge means that the top of the box 4 has an outer edge, but its surface and side can also be flat, such as a standard honeycomb box, and for the box 4 with a protruding edge, the hanging rollers can be used to transmit according to the need, so that the rollers 22 with two hanging sides can just block the position of the protruding edge of the box 4, and ensure that each position of the surface of the box 4 can be effectively irradiated by the electron beam, so that in combination with the previous embodiment, the hanging small rollers 22 matching with the protruding edge on the top of the box 4 can be used to transmit according to the need, or the small diameter rotating roller 21 can be used to transmit according to the need at the bottom of the box 4 to meet the needs of sterilization treatment and transmission of boxes 4 of different styles, the flat box 4 is not referred to herein as a flat box 4, the actual box has a plurality of small concave structures, and the transmission by the structure of the roller structure is not influenced

In another embodiment, the transport assembly further comprises a limiting roller 23 which is in clearance fit with the upper surface of the box 4.

(the structure is advantageous in that only the position of the window is provided with the limiting roller 23, namely the limiting roller 23 is added above the box corresponding to the window, the spacing between the rotating roller 21 or the hanging roller 22 at the window position is larger, in order to prevent the box 4 from falling down and affecting the irradiation dose in the transmission process, or the box 4 touches the window due to falling or tilting in the transmission process to cause damage of the window and ensure the stability of the use in the transmission process, in the actual application, two free ends of the limiting roller 23 can be matched with the matched bearings, and further the roller can be installed on the inner wall of the shielding chamber 1 directly through the bearing seat matched with the bearings or through the matched fixing piece, so that the limiting roller 23 can rotate along with the transmission of the box 4 without generating interference acting force on the box 4, the additional limiting rollers 23 can also be connected in an alternative manner, which serves as a transport guide for the cassettes in space, as well as a spatial limitation in the case of an excessively large span or spacing between the rollers of the irradiation field, while at the same time effectively preventing the cassettes 4 from tilting)
