Description

Technical Field

[0001] The utility model relates to the technical field of irradiation equipment, in particular to an irradiation box with circular motion. Background Art

[0002] Irradiation is a technique that uses radiation sources, such as electromagnetic waves or high-speed particles, to irradiate matter, inducing physical, chemical, or biochemical changes within the material. Irradiation technology is widely used in various fields, particularly in the medical and food processing industries. Irradiation chambers are often used for sterilization and disinfection, ensuring the sterility of medical devices and pharmaceuticals, effectively extending the shelf life of food, and inhibiting microbial growth.

[0003] Irradiation is very harmful to the human body, so the source racks used to generate gamma rays are stored in the source storage well for preservation and then raised by the lifting device when needed. The radioactive source in the source rack generates gamma rays, which are emitted directly through the cladding. During irradiation, uneven irradiation is likely to occur. Due to excessive cargo loading or high density in the box, the gamma rays have been greatly attenuated by the time they reach the middle part, that is, the dose rate of the gamma rays becomes low. At this time, the cargo far away from the source rack receives less cumulative dose, which causes the unevenness to continue to increase. In response to the above problems, the utility model proposes an irradiation box and a mobile device thereof that can improve the uniformity of irradiation. Utility Model Content

[0004] The utility model aims to provide an irradiation box with annular motion, which is arranged on a source storage well and can drive the irradiation box to revolve around the radiation source while rotating on its own, thereby improving the uniformity of irradiation.

[0007] As a preferred technical solution, the upper surface of the gear is flush with the upper surface of the ring gear.

The slider can be slidably arranged on the annular slide rail. The slider passes through the through groove and is rotatably connected to the gear.

[0010] As an optimal technical solution, the irradiation box also includes several side support plates, which are fixedly arranged between the bottom plate and the top plate. The side support plates are located at the outermost side of the bottom plate, and the inner side of the side support plates is fixedly connected to the outer side of several placement plates.

[0022] Example

[0023] like Figure 1-2As shown, a circularly moving irradiation box includes an irradiation box and a moving device, the moving device includes a base 1, a ring gear 2, a baffle 3, a gear 4 and a driving device, the base 1 is a circular ring structure, the ring gear 2 and the baffle 3 are fixedly arranged on the top of the base 1, the ring gear 2 is located on the outside of the circular ring base 1, the baffle 3 is located on the inside of the circular ring base 1, the gear 4 is arranged between the ring gear 2 and the baffle 3, the gear 4 is meshed with the ring gear 2, the driving device is arranged at the bottom of the gear 4, and a circular ring-shaped through groove for the driving device to pass through is opened on the base 1, the irradiation box is fixedly set on the top of the gear 4, the irradiation box includes a bottom plate 8, a top plate 9, a pillar 10 and a plurality of placement plates, the pillar 10 is fixedly set on the top of the bottom plate 8, the top plate 9 is fixedly set on the top of the pillar 10, and a plurality of placement plates are fixedly set on the pillar 10.

[0024] It is worth noting that the irradiation box is used to load the products to be irradiated, and the movement of the irradiation box around the radiation source is controlled by the movement device. Specifically, the products to be irradiated are placed in the irradiation box. The drive device drives the gear 4 and the irradiation box on top of the gear 4 to move along the annular groove on the base 1. The ring gear 2 drives the annular gear 4 to rotate, which in turn drives the irradiation box to rotate with the gear 4. The baffle 3 limits and protects the ring gear 2.

[0025] It should be noted that the radiation source is 60 Co single-plate source structure. Since the radiation from the radioactive source is harmful to the human body, the radioactive source is placed in a source storage well when the radioactive source is not in working state. When irradiation work is required, the radioactive source is lifted out of the water surface by a special lifting tool. Therefore, the base 1 is fixedly set on the source storage well, and the source storage well is located in the hollow circle of the annular base 1.

[0026] In some feasible embodiments, the upper surface of the gear 4 is flush with the upper surface of the ring gear 2 to prevent the ring gear 2 and the baffle 3 from restricting the rotation of the irradiation box.

[0027] In some feasible embodiments, the drive device includes a U-shaped groove 5, an annular slide 6, and a slider 7. The annular slide 6 is an electric slide. The annular slide 6 is an existing structure, and this embodiment only briefly describes this existing technology. The toothed annular slide 6 engages with a gear on the slider 7. The motor is disposed in a mounting cavity within the slider 7, which has a gear hole. The gear connected to the motor output extends through the gear hole and engages with the annular slide 6. The annular slide 6 is custom-made, and the motor has been treated for radiation protection, which can resist the effects of radiation sources on electronic equipment.

[0028] The U-shaped groove 5 is fixedly set at the bottom of the base 1. The U-shaped groove 5 is a circular ring structure. The U-shaped groove 5 is located below the circular ring-shaped through groove on the base 1. The annular slide rail 6 is fixedly set in the U-shaped groove 5. The slider 7 is slidably set on the annular slide rail 6. The slider 7 passes through the through groove and is rotatably connected to the gear 4. The slider 7 moves on the annular slide rail 6, driving the irradiation box to move with the slider 7.

[0029] Specifically, the slider 7 drives the gear 4 to perform annular motion, and the gear 4 rotates under the action of the ring gear 2, thereby driving the irradiation box to revolve around the radiation source while also rotating, so that the products in the irradiation box are irradiated with gamma rays, thereby improving the uniformity of the products in the irradiation box being exposed to gamma rays.

[0030] In some feasible embodiments, the irradiation box also includes a number of side support plates 11, which are fixedly arranged between the bottom plate 8 and the top plate 9. The side support plates 11 are located at the outermost side of the bottom plate 8, and the inner side of the side support plates 11 is fixedly connected to the outer side of the number of placement plates. The side support plates 11 provide support for the number of placement plates.

[0031] In some feasible embodiments, the irradiation chamber further includes a transparent door panel, which is disposed between two adjacent side support panels 11, with one side of the door panel hinged to the side support panel 11. Opening the door panel facilitates placing products to be irradiated into the irradiation chamber, and during irradiation, the transparent door panel does not obstruct the passage of gamma rays.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art. So far, the various embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here. The scope of the present disclosure is defined by the appended claims.
