[0052] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0053] Embodiment 1

[0054] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a packaging tube, comprising:

[0055] A tube body 1, the upper end of which is an open structure;

[0056] A cover body 2, which is arranged at the opening of the tube body 1 to seal the tube body 1, wherein the sealing contact portion between the cover body 2 and the tube body 1 is located on the outer side of the tube body 1, and the outer side of the cover body 2 is flush with the outer side of the tube body 1;

[0057] The lifting member 3 is arranged on the surface of the cover body 2 .

[0058] In this embodiment, the waste source is placed inside the tube body 1, and cement is injected into the tube body 1. After the cement injection is completed, the cover body 2 is placed at the opening of the tube body 1, and the cover body 2 and the tube body 1 are welded to complete the packaging;

[0059] Since the sealing contact part between the cover body 2 and the tube body 1 is located on the outer side of the tube body 1, it is not easy for cement to remain around the sealing contact part between the cover body 2 and the tube body 1. Therefore, when the cover body 2 and the tube body 1 are welded, residual cement will not enter the welding molten part during the welding process, which can ensure the air tightness of the welding between the cover body 2 and the tube body 1; at the same time, during welding, the cover body 2 is heated in the same plane, which can effectively prevent the edge of the cover body 2 from warping, thereby ensuring the welding quality of the cover body 2 and the tube body 1;

[0060] The packaging tube is lifted by the lifting device in cooperation with the lifting machine, which facilitates the transfer and arrangement of the packaging tube, prevents the packaging tube from falling during the transfer and arrangement process, ensures the safety of the packaging tube, and facilitates the automated transfer and arrangement of the packaging tube.

[0061] The outer side surface of the cover body 2 is flush with the outer side surface of the tube body 1, which facilitates the welding of the cover body 2 and the tube body 1 and ensures the welding quality;

[0062] The material of the tube body 1 in this embodiment is TP304 stainless steel, and the wall thickness of the tube body 1 is 3 mm.

[0063] like Figure 1 As shown, in an optional embodiment of the present invention, the packaging tube further includes:

[0064] The positioning portion 21 is arranged on the bottom surface of the cover body 2 , and the outer side surface of the positioning portion 21 is in full contact with the inner wall of the inner cavity of the tube body 1 .

[0065] In this embodiment, since the outer side surface of the positioning portion 21 is in full contact with the inner wall of the inner cavity of the tube body 1, when the cover body 2 is placed in the opening of the tube body 1, the positioning portion 21 is used to position the inner cavity of the tube body 1, thereby ensuring the placement stability of the cover body 2. At the same time, it can ensure that the outer side surface of the cover body 2 is accurately flush with the outer side surface of the tube body 1, thereby ensuring the welding quality of the cover body 2 and the tube body 1;

[0066] In this embodiment, the positioning portion 21 may be a disc-shaped structure, or may be a ring-shaped structure or other structures that can cooperate with the inner wall of the inner cavity of the tube body 1 to position the cover body 2 .

[0067] like Figure 3 As shown, in an optional embodiment of the present invention, the lifting member includes:

[0068] A connecting column 31, the connecting column 31 is connected to the upper surface of the cover body 2, and the connecting column 31 and the cover body 2 are coaxially arranged;

[0069] The limiting plate 32 is connected to the upper end of the connecting column 31 , and the limiting plate 32 and the connecting column 31 form a structure with a T-shaped cross section.

[0070] In this embodiment, a lifting member is formed by connecting a column 31 and a limiting plate 32, and the lifting member cooperates with a lifting machine to lift the packaging tube, which facilitates the transfer and arrangement of the packaging tube, avoids the packaging tube from falling during the transfer and arrangement process, and ensures the safety of the packaging tube.

[0071] like Figure 1 and Figure 3 As shown, in an optional embodiment of the present invention, the tube body 1 is a cylindrical structure.

[0072] In this embodiment, the cylindrical tube body 1 is mainly used to encapsulate waste sources with small volume and high activity;

[0073] The tube body 1 is a cylindrical structure with a diameter of 80 mm, a height of 100 mm, and a volume of 502400 mm. 3 Compared with the existing packaging tubes, the longitudinal height of the packaging tubes is reduced. Under the condition that the total activity of the radioactive source packaged in a single packaging tube is limited, the arrangement of the packaging tubes inside the 200L steel drum is more reasonable, and the number of packaging tubes can be increased as much as possible without overlapping the packaging tubes in the longitudinal direction, thereby increasing the utilization rate of the 200L steel drum; at the same time, the position of the packaging tubes can be appropriately adjusted inside the steel drum, thereby optimizing the radiation shielding of the fixed medium in the drum.

[0074] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, the packaging tube further includes:

[0075] The limiter is placed inside the tube body 1 , and the limiter is located above the waste source placed inside the tube body 1 to limit and fix the waste source inside the tube body 1 .

[0076] In this embodiment, when encapsulating multiple waste sources, when cement is injected into the tube body 1, since the density of cement is greater than the density of the waste sources, the waste sources will float up, affecting the encapsulation effect. In order to solve the problem of the floating of the waste sources, after the waste sources are placed in the tube body 1, the limiter is placed inside the tube body 1, and the waste sources are limited and fixed inside the tube body 1 by the limiter. When pouring cement, the cement does not contact the waste sources, thereby effectively preventing the waste sources from floating up and ensuring the waste source encapsulation effect.

[0077] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, the limiter includes:

[0078] The support portion 4 has a conical structure;

[0079] A gripping portion 6 connected to the top of the supporting portion 4;

[0080] The elastic part 5 is formed at the bottom edge of the grabbing part 6 , and the elastic part 5 is in full contact with the inner wall of the tube body 1 to fix the stopper inside the tube body 1 .

[0081] In this embodiment, when placing the stopper, the grabbing portion 6 is grasped, and the supporting portion 4 and the elastic portion 5 are placed inside the tube body 1. The elastic portion 5 is in full contact with the inner wall of the inner cavity of the tube body 1. Under the elastic force of the elastic portion 5, the stopper is fixed inside the tube body 1, so that the waste source is fixed inside the tube body 1 by the stopper;

[0082] In this embodiment, in order to reduce the weight of the support part 4 and save costs, the support part 4 is a conical shell structure; in specific applications, the support part 4 can also be a conical structure of other forms, which is not specifically limited here;

[0083] The gripping portion 6 is a columnar structure, and the gripping portion 6 may also be other structures that are convenient for gripping, which will not be specifically limited here;

[0084] To ensure the elastic effect of the elastic part 5, in this embodiment, the elastic part 5 is a ring structure with an arc-shaped cross-section. In specific applications, the elastic part 5 can also be other structures that can use its own elasticity to fully contact the inner wall of the inner cavity of the tube body 1 to fix the limiter inside the tube body 1. No specific limitation is made here.

[0085] like Figure 4 and Figure 5 As shown, in an optional embodiment of the present invention, the packaging tube further includes:

[0086] An inner sleeve 7, the outer diameter of the inner sleeve 7 is adapted to the inner diameter of the inner cavity of the tube body 1;

[0087] The accommodating chamber 71 for accommodating the waste source is arranged inside the inner sleeve 7 . The accommodating chamber 71 extends along the axial direction of the inner sleeve 7 and penetrates the surface and bottom surface of the inner sleeve 7 .

[0088] In this embodiment, when encapsulating a single or a small number of waste sources, the inner sleeve 7 is placed inside the tube body 1, the single or a small number of waste sources are placed inside the accommodating cavity 71, and cement is injected into the accommodating cavity 71 to achieve waste source encapsulation; by placing a single or a small number of waste sources inside the accommodating cavity 71, it is possible to limit the position of the single or a small number of waste sources, so that the single or a small number of waste sources are concentrated inside the accommodating cavity 71, thereby preventing the single or a small number of waste sources from approaching the inner wall of the tube body 1, and at the same time, the inner sleeve 7 can be used to effectively shield the radiation and reduce the exposure dose of personnel.

[0089] Embodiment 2

[0090] The difference between the second embodiment and the first embodiment lies in the shape of the tube body 1;

[0091] like Figure 6 and Figure 7 As shown, in an optional embodiment of the present invention, the tube body 1 is a rectangular structure.

[0092] In this embodiment, the rectangular tube 1 is mainly used for packaging low-activity radiation sources, which are mainly surface sources. They are generally larger in size and have lower activity.

[0093] The rectangular tube body 1 has a length of 200 mm, a width of 140 mm, a height of 100 mm, and a volume of 2800000 mm 3 The maximum size of a common surface source is 190 mm*130 mm, and the rectangular tube body 1 can effectively encapsulate the surface source.

[0094] Packaging process of a single packaging tube:

The waste source is fixed to the bottom of the inner cavity of the tube body 1 by the stopper, and cement is injected into the tube body 1. After the cement injection is completed, the cover body 2 is placed at the opening of the tube body 1, so that the positioning part 21 enters the tube body 1 The cover body 2 and the tube body 1 are welded to complete the packaging of a single packaging tube; when the waste source to be packaged is single or small in number, the inner sleeve 7 is placed inside the tube body 1, and a single or a small amount of waste source is placed inside the accommodating cavity 71, and cement is injected into the accommodating cavity 71. After the cement is injected, the cover body 2 is placed at the opening of the tube body 1, so that the positioning part 21 enters the tube body 1 and the positioning part 21 is fully in contact with the inner wall of the inner cavity of the tube body 1, and the cover body 2 and the tube body 1 are welded to complete the packaging of a single packaging tube;

[0096] A rectangular tube body 1 is used to encapsulate a large-volume, low-activity surface source. The surface source is placed inside the tube body 1, and cement is injected into the tube body 1. After the cement is injected, the cover body 2 is placed at the opening of the tube body 1, so that the positioning portion 21 enters the tube body 1 and the positioning portion 21 is in full contact with the inner wall of the inner cavity of the tube body 1. The cover body 2 and the tube body 1 are welded to complete the encapsulation of a single encapsulated tube.

[0117] Specific packaging process:

[0118] The packaging of a single packaging tube uses a cylindrical tube body 1 to package waste sources with small volume and high activity. When the number of packaged waste sources is large, the waste sources are placed inside the tube body 1, the grasping part 6 is held, the support part 4 and the elastic part 5 are placed inside the tube body 1 and close to the waste sources, and the elastic force of the elastic part 5 is used to make the elastic part 5 fully contact with the inner wall of the inner cavity of the tube body 1, and the stopper is fixed inside the tube body 1.
