Description

Technical Field

[0001] The utility model relates to the technical field of electron beam irradiation, and particularly relates to a stackable tray for electron beam irradiation. Background Technique

[0002] In order to enable materials to operate normally and efficiently on the electron beam irradiation transmission system, metal trays are usually used to load the irradiated objects to prevent products with different packaging specifications, packaging materials, product specific gravities, etc. from being transported normally on the beam-down transmission system, and the transmission speed can be controlled. The tray structure is simple, the cost is low and the stability is good. Most of the materials under the accelerator irradiation adopt the tray method. Existing irradiation trays are all single-layer trays, that is, the materials are directly placed on the trays and then irradiated. However, for some products with low specific gravity, such as products with a specific gravity less than 0.1, the electron beam penetration depth can reach 500 mm. If a single-layer tray is used, in order to ensure the irradiation efficiency, the packaging volume of the product or the stacking height of the irradiation needs to be increased. In this way, during actual processing, it is easy to have problems such as the materials being stacked and prone to tipping over during beam-down transmission, or the internal temperature of the materials may rise due to the large packaging size during irradiation, thus seriously affecting the irradiation effect on the materials. Therefore, we propose a stackable tray for electron beam irradiation. Content of the Utility Model

The utility model solves the problems that for some products with low specific gravity, such as products with a specific gravity less than 0.1, the electron beam penetration depth can reach 500 mm. If a single-layer tray is used, in order to ensure the irradiation efficiency, the packaging volume of the product or the stacking height of the irradiation needs to be increased. In this way, during actual processing, it is easy to have problems such as the materials being stacked and prone to tipping over during beam-down transmission, or the internal temperature of the materials may rise due to the large packaging size during irradiation, thus seriously affecting the irradiation effect on the materials.

The lower end of the inner rod is fixedly connected with a threaded rod. A support rod matching the inner rod is provided above the skirt. A limit block is fixedly connected above the support rod.

[0020] The following will further describe the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0021] As Figures 1-4 shown, the present utility model is a stackable tray for electron beam irradiation. The present utility model solves the problem that for some products with low specific gravity, such as products with a specific gravity less than 0.1, the electron beam penetration depth can be 500 mm. If a single-layer tray is used, in order to ensure the irradiation efficiency, the product packaging volume or the height of the irradiation stack needs to be increased. In this way, during actual processing, when the materials are stacked and placed, it is easy to have faults such as tipping during transmission under the beam, or the internal temperature may rise during irradiation due to the large size of the material packaging, thus seriously affecting the irradiation effect on the materials.

[0022] A stackable tray for electron beam irradiation in the present utility model includes a tray body 1. A skirt 2 is provided on the outer side of the upper end of the tray body 1. Four outer tubes 3 arranged in a matrix are provided below the skirt 2. An inner rod 4 is inserted at the lower end of the outer tube 3. The inner rod 4 is movably connected to the outer tube 3. The inner rod 4 can move vertically inside the outer tube 3. By adjusting the degree of connection between the inner rod 4 and the outer tube 3, the height of the lower support part formed by the inner rod 4 and the outer tube 3 can be adjusted. The lower part of the inner rod 4 is fixedly connected to a threaded rod 5. A support rod 6 matching the inner rod 4 is provided above the skirt 2. A limit block 7 is fixedly connected above the support rod 6. A connecting ring 8 is sleeved on the upper end of the support rod 6. An internal thread 9 matching the threaded rod 5 is provided on the inner wall of the connecting ring 8. When splicing two adjacent tray bodies 1, the connecting ring 8 is rotated. Through the mutual cooperation between the internal thread 9 on the inner wall of the connecting ring 8 and the threaded rod 5, the threaded rod 5 and the connecting ring 8 can be stably connected.

[0023] The tray body 1 and the skirt 2 are of an integral structure.

[0024] Anti-slip lines 10 are provided on the outer side of the connecting ring 8. The anti-slip lines 10 effectively increase the friction between the fingers and the connecting ring 8, thus making it more convenient for the staff to rotate the connecting ring 8.

[0025] Lifting handles 11 are provided on both sides above the skirt 2. The provision of the lifting handles 11 makes it more convenient for the staff to pick up and place the tray body 1.

[0026] A fastening bolt 12 is provided at the lower end of the outer tube 3. The fastening bolt 12 can position the outer tube 3 and the inner rod 4.

[0027] Both sides of the upper end of the inner rod 4 are provided with sliders 13. The inner wall of the outer tube 3 is provided with a chute 14 that matches the slider 13. The slider 13 can slide inside the chute 14. At the same time, the chute 14 can limit the slider 13, avoiding the phenomenon that the inner rod 4 rotates inside the outer tube 3.

[0028] Specifically, in the present utility model, the inner rod 4 can move vertically inside the outer tube 3. By adjusting the degree of communication between the inner rod 4 and the outer tube 3, the height of the lower support part formed by the inner rod 4 and the outer tube 3 can be adjusted. At the same time, the outer tube 3 and the inner rod 4 can be positioned by the fastening bolt 12. When splicing two adjacent tray bodies 1, rotate the connecting ring 8. Through the mutual cooperation between the internal thread 9 on the inner wall of the connecting ring 8 and the threaded rod 5, the threaded rod 5 and the connecting ring 8 can be stably connected.

[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
