[0031] The embodiments of the present application provide an irradiation processing system for irradiation processing. Irradiation processing refers to the process of irradiating materials with radiation such as gamma rays or electron beams, which is widely used in food sterilization, medical device disinfection, pollutant treatment and material strengthening and many other technical fields. During irradiation processing, the radiation interacts with the material, causing the material to undergo degradation, polymerization and crosslinking, etc.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 The irradiation processing system provided by the embodiments of the present application comprises an irradiation accelerator, an irradiation transmission line 1 and a first shielding structure 2. The irradiation transmission line 1 extends in a closed loop shape. The first shielding structure 2 forms a first shielding cavity 3, the first shielding cavity 3 extends along the irradiation transmission line 1, a part of the irradiation transmission line 1 is accommodated in the first shielding cavity 3, the first shielding cavity 3 comprises a body part 31 and two bending parts 32, a target point 4 of the irradiation accelerator is located in the middle of the body part 31, the irradiation transmission line 1 extends out of the first shielding cavity 3 along the extension path through the ends 322 of the two bending parts, the two bending parts 32 are respectively arranged at the two ends of the body part 31, the first end 321 of the bending part and the extension direction of the body part 31 have an included angle, and along the width direction a of the body part, the two bending parts 32 are respectively located on opposite sides of the body part 31.

[0033] The irradiation processing system provided by the embodiments of the present application has two bending portions 32 respectively located at opposite sides of the body portion in the width direction a, and the two bending portions 32 are located at the same side of the body portion 31 in the width direction, which is beneficial to make the two bending portions 32 occupy less space in the length direction of the body portion 31, and the first shielding structure 2 has an overall strip shape extending in the width direction a of the body portion, thereby making the irradiation processing system occupy a more reasonable space and not easily limited by the site. Moreover, the irradiation processing system with such a structure is more adaptable to a truck, a train or a container 93, so that the irradiation processing system can be conveniently transported.

[0034] It should be explained that, please refer to Figure 1 、 Figure 2 and Figure 3 The irradiation transmission line 1 is used for transmitting materials to make the materials move to the target point 4 of the irradiation accelerator to receive irradiation. In the case that the irradiation transmission line 1 transmits a plurality of materials, the plurality of materials will be arranged along the extension path of the irradiation transmission line 1. The front material will continue to move forward under the driving of the irradiation transmission line 1 after receiving irradiation and leave the target point 4, so as to make space for the rear material which has not received irradiation to move to the target point 4 to receive irradiation, so that the plurality of materials will move to the target point 4 in turn to receive irradiation. Here, the front and the rear refer to the front and the rear in the movement direction, and the materials will move along the extension path of the irradiation transmission line 1, and the rear material will move forward.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 3, the irradiation transmission line 1 extends in a closed loop, i.e. the irradiation transmission line 1 carries the material in a loop path, i.e. the movement path of the material is a loop or a part of a loop, etc. The irradiation transmission line 1 is partially accommodated in the first shielding cavity 3 and partially located outside the first shielding cavity 3, so that the irradiation transmission line forms a closed loop transmission. Specifically, the irradiation transmission line 1 extends out of the first shielding cavity 3 through the ends 322 of the two bending portions, i.e. the two ends of the part of the irradiation transmission line 1 located outside the first shielding cavity 3 are connected through the ends 322 of the two bending portions and the two ends of the part of the irradiation transmission line 1 located inside the first shielding cavity 3 to form the irradiation transmission line 1 extending in a closed loop. The part of the irradiation transmission line 1 located outside the first shielding cavity 3 is used for feeding and discharging the material, where the discharging refers to taking the material that has received irradiation from the part of the irradiation transmission line 1 located outside the first shielding cavity 3, and the feeding refers to placing the material that has not received irradiation on the part of the irradiation transmission line 1 located outside the first shielding cavity 3. After the feeding, the material that has not received irradiation is moved from outside the first shielding cavity 3 to the target point 4 inside the first shielding cavity 3 through the end 322 of one bending portion to receive irradiation, and after receiving irradiation, the material is moved from inside the first shielding cavity 3 to outside the first shielding cavity 3 through the end 322 of the other bending portion for discharging. In this way, a closed loop transmission is formed, and a plurality of materials on the irradiation transmission line 1 can be sequentially subjected to the above process.

[0036] It needs to be explained that, please refer to Figure 1 、 Figure 2 and Figure 3 , the target point 4 of the irradiation accelerator is located in the middle of the body portion 31, i.e. the material receives irradiation from the irradiation accelerator in the body portion 31, and along the extension direction of the body portion 31, the target point 4 is located between the first ends 321 of the two bending portions. The extension direction of the body portion 31 is parallel to the line connecting one end of the body portion 31 connected with one bending portion 32 and the other end of the body portion 31 connected with the other bending portion 32, and the width direction a of the body portion is perpendicular to the extension direction of the body portion 31. The first end 321 of the bending portion is the end of the bending portion 32 connected with the body portion 31, and the end 322 of the bending portion is the other end of the extension path of the bending portion 32.

[0037] Please refer to Figure 1 、 Figure 2 and Figure 3 , in some optional embodiments in the present application, the first ends 321 of the two bending portions are symmetrically relative to the center of the target point 4. With this structure, the arrangement of the two bending portions 32 is more reasonable, which is beneficial to further improve the space utilization and further reduce the occupied space of the irradiation processing system.

[0038] Please refer to Figure 1 、 Figure 2 andFigure 3 In some optional embodiments of the present application, at least one of the cavity sections of at least one of the bending portions 32 is bent towards the end of the bending portion 32 which is away from the body portion 31. In this way, the space occupied by the bending portion 32 in the extension direction of the body portion 31 can be further reduced. For example, the leading end 321 of one of the bending portions can be bent towards the end of the bending portion 32 which is away from the body portion 31, so that the leading end 321 of one of the bending portions and the body portion 31 form a U-shaped structure or a V-shaped structure, etc.

[0039] Further, referring to Figure 1 , Figure 2 and Figure 3 In some optional embodiments of the present application, the irradiation processing system further comprises a support structure 98 installed at the bottom of the first shielding structure 2 for supporting the first shielding structure 2.

[0040] Further, referring to Figure 4 In some optional embodiments of the present application, the first shielding structure 2 comprises a first lower shielding body 21 and a first upper shielding body 22. The upper end of the first upper shielding body 22 is coupled with the first lower shielding body 21 to form the first shielding cavity 3, and a first stepped surface 23 is formed between the first upper shielding body 22 and the first lower shielding body 21. The first stepped surface 23 extends along the circumference of the first upper shielding body 22, and the first upper shielding body 22 and the first lower shielding body 21 are connected by the first stepped surface 23. In this way, the first shielding structure 2 is formed by assembling, which is convenient and can improve the work efficiency on the construction site. Optionally, the first lower shielding body 21 and the first upper shielding body 22 can be assembled together by hoisting. The first lower shielding body 21 and the first upper shielding body 22 are connected by the first stepped surface 23, which can improve the stability of the installation of the first lower shielding body 21 and the first upper shielding body 22, and can also ensure the shielding effect of the first lower shielding body 21 and the first upper shielding body 22.

[0041] Referring to Figure 4The implementation forms of the first stepped surface 23, the second stepped surface 75 and the third stepped surface 76 can be various. Exemplarily, the first stepped surface 23 is taken as an example for description, and the second stepped surface 75 and the third stepped surface 76 are the same. In some optional embodiments of the present application, the first stepped surface 23 is formed by a first bottom surface, a second bottom surface and a connecting surface. The first bottom surface, the second bottom surface and the connecting surface all extend along the circumferential direction of the arrangement direction of the first upper shielding body 22 and the first lower shielding body 21, the first bottom surface and the second bottom surface are arranged along the radial direction of the first upper shielding body 22, the first bottom surface is lower than the second bottom surface, and the two ends of the connecting surface in the width direction are respectively connected to one end of the first bottom surface in the width direction and one end of the second bottom surface in the width direction to form the first stepped surface 23. It needs to be explained that the width direction is perpendicular to the extension direction and parallel to the extension surface. The first bottom surface and the second bottom surface are arranged along the radial direction of the first upper shielding body 22, that is, the first bottom surface can be arranged around the second bottom surface, or the second bottom surface can be arranged around the first bottom surface, that is, the first bottom surface can be located in the second bottom surface, or the second bottom surface can be located in the first bottom surface. On this basis, in some optional embodiments of the present application, the first bottom surface and the second bottom surface are in the same direction, and both are parallel to the arrangement direction of the first lower shielding body 21 and the first upper shielding body 22. In this structure, the connection between the first lower shielding body 21 and the first upper shielding body 22 is more stable.

[0042] In addition, please refer to Figure 4 The first stepped surface 23 is formed between the first upper shielding body 22 and the first lower shielding body 21, which can be that only one of the first lower shielding body 21 and the first upper shielding body 22 is formed with the first stepped surface 23, and the end of the other one is abutted on the first bottom surface; or the first lower shielding body 21 and the first upper shielding body 22 can be both formed with the first stepped surface 23, and the two first stepped surfaces 23 cooperate with each other.

[0043] In some optional embodiments of the present application, please refer to Figure 4The lower shielding body includes a first bottom shielding body 211 and a first middle shielding body 212. The first bottom shielding body 211 is formed with a mounting groove 2111 extending along the circumference of the first upper shielding body 22, and the mounting groove 2111 faces upward. The first upper shielding body 22 is fastened to the upper end of the first middle shielding body 212. The first middle shielding body 212 includes a plurality of sub-middle shielding bodies arranged in a closed ring structure along the circumference of the first upper shielding body 22, and the lower end of each sub-middle shielding body is matched with the mounting groove 2111. In this way, during the assembly of the first shielding structure 2, the first bottom shielding body 211 can be first installed at a predetermined position to provide a foundation, and then the plurality of sub-middle shielding bodies can be installed in the mounting groove 2111 to form a closed one-week structure, and finally the first upper shielding body 22 is fastened to the upper end of the plurality of sub-middle shielding bodies to complete the assembly. The entire assembly process is relatively simple, and the first shielding structure 2 formed by the assembly is relatively stable. The first middle shielding body 212 is divided into a plurality of sub-middle shielding bodies, which facilitates assembly and transportation. The mounting groove 2111 can provide a reliable mounting position for the sub-middle shielding body, so that the sub-middle shielding body and the first bottom shielding body 211 are relatively stable.

[0044] Further, please refer to Figure 4 In some optional embodiments of the present application, an opening 24 is formed on the first shielding structure 2, and the profile of the opening 24 is larger than that of the scanning box 51 of the irradiation accelerator, so that the scanning box 51 can extend into the first shielding cavity 3 through the opening 24. The irradiation processing system further includes a second shielding structure 6 which is detachably arranged on the opening 24. The second shielding structure 6 is formed with a through hole 61, and the head 5 of the irradiation accelerator is arranged in the through hole 61, so that the scanning box 51 is located on the side of the second shielding structure 6 close to the first shielding cavity 3, and the head 5 of the irradiation accelerator is attached to the inner wall of the through hole 61. In this way, the scanning box 51 is used to emit radiation in the first shielding cavity 3, and the second shielding structure 6 is used to close the opening 24, which can effectively shield the scanning box 51 and has a strong shielding effect. The second shielding structure 6 can effectively reduce the shielding pressure of the third shielding structure 7. On the basis of the second shielding structure 6, the thickness of the third shielding structure 7 is greatly reduced, thereby greatly reducing the space occupied by the irradiation processing system. Generally, the opening 24 faces upward, and the arrangement of the second shielding structure 6 can greatly reduce the space occupied by the irradiation processing system in the upward and downward direction b. The upward and downward direction b is the arrangement direction of the first lower shielding body 21 and the first upper shielding body 22.

[0045] In some optional embodiments of the present application, please refer to Figure 4The support plate is arranged between the side of the scanning box 51 close to the scanning box 51 shielding body and the scanning box 51 shielding body, and the scanning box 51 shielding body is fixedly connected with the scanning box 51 through the support plate.

[0046] In some optional embodiments of the present application, please refer to Figure 4 The second shielding structure 6 is supported on the first shielding structure 2 at one side in the first shielding cavity 3, and the second shielding structure 6 is fixedly connected with the head 5 of the irradiation accelerator, so that the head 5 of the irradiation accelerator is supported on the first shielding structure 2. With this structure, the second shielding structure 6 plays a shielding role on one hand and a fixed support role on the other hand, so that the head 5 is stably installed on the first shielding structure 2, and the structure is relatively compact. On this basis, in some optional embodiments, the head 5 includes a head 5 body and a head 5 support, the head 5 is installed in the head 5 support, and the head 5 support is fixed with the second shielding body. In some optional embodiments, the head 5 support, the head 5 body and the second shielding body can be installed together for hoisting.

[0047] Further, please refer to Figure 4 In some optional embodiments of the present application, the irradiation processing system further includes a third shielding structure 7, one end of the third shielding structure 7 abuts against the outer wall of the first shielding structure 2 and surrounds the opening 24, and the other end extends away from the first shielding structure 2, so that the second shielding cavity 71 is formed between the first shielding structure 2 and the third shielding structure 7, and the head 5 of the irradiation accelerator is located in the second shielding cavity 71. With this structure, the second shielding cavity 71 is used for shielding the head 5 of the irradiation accelerator, further reducing the radiation influence. In some optional embodiments of the present application, on the basis of the second shielding structure 6, the third shielding structure 7 is located in the second shielding cavity 71. In this way, the second shielding structure 6 can greatly reduce the shielding pressure of the third shielding structure 7, so that the thickness of the third shielding structure 7 is greatly reduced, and the space occupied by the irradiation processing system is greatly reduced.

[0048] Please refer to Figure 4 In some optional embodiments of the present application, a threading hole 72 is formed in the side wall of the third shielding structure 7, a connecting line is arranged in the threading hole 72, the connecting line is electrically connected between the head 5 of the irradiation accelerator and the control device, and the threading hole 72 has a curvature. With this structure, the threading hole 72 has a curvature, so that the arrangement of the threading hole 72 does not greatly affect the shielding effect. On this basis, in some optional embodiments of the present application, the threading hole 72 extends in a wave shape.

[0049] Further, please refer to Figure 4In some optional embodiments of the present application, the third shielding structure 7 comprises a second lower shielding body 73 and a second upper shielding body 74. The lower end of the second lower shielding body 73 is in abutment with the outer wall of the first shielding structure 2 and surrounds the opening 24. The second upper shielding body 74 is fastened to the upper end of the second lower shielding body 73 to form a second shielding cavity 71. A second stepped surface 75 is formed between the second upper shielding body 74 and the second lower shielding body 73. The second stepped surface 75 extends circumferentially along the second upper shielding body 74. The second upper shielding body 74 and the second lower shielding body 73 are connected by the second stepped surface 75. In this way, the third shielding structure 7 is formed by assembling, which is convenient and helps to improve the work efficiency on the construction site. Optionally, the second lower shielding body 73 and the second upper shielding body 74 can be assembled together by hoisting. The second lower shielding body 73 and the second upper shielding body 74 are connected by the second stepped surface 75, which helps to improve the stability of the installation of the second lower shielding body 73 and the second upper shielding body 74 and to ensure the shielding effect of the second lower shielding body 73 and the second upper shielding body 74.

[0050] For a better understanding of the present application, refer to Figure 4 In some optional embodiments of the present application, the inner wall of the second lower shielding body 73 is supported by the circumferential outer wall of the head 5 of the irradiation accelerator.

The second middle shielding body 732 is supported between the second bottom shielding body 731 and the second upper shielding body 74. A third stepped surface 76 is formed between the second bottom shielding body 731 and the second middle shielding body 732. The third stepped surface 76 extends circumferentially along the head 5 of the irradiation accelerator.
