Description

Technical Field

[0001] This utility model mainly relates to the field of irradiation equipment technology, and in particular to a storage rack for electron beam irradiation. Background Technology

[0002] Electron beam irradiation technology is another high-tech application of nuclear technology in industrial irradiation, in addition to gamma irradiation. Currently, this technology has been applied in many fields such as food sterilization, medical device disinfection, and material modification, and has a very broad application prospect.

[0003] During irradiation, the products to be irradiated are usually placed on shelves, which are then mounted on a conveyor system (usually a roller conveyor belt). Driven by the conveyor system, the shelves carrying the products to be irradiated move along the irradiation production line and are then irradiated.

[0004] Most existing shelves are in the form of ordinary trays, which work well with conveying devices and are suitable for carrying and moving items. However, since the irradiation direction is usually vertical, the bottom plate of the tray can obstruct the electron beam, thereby reducing irradiation efficiency. Therefore, it is necessary to improve the structure of shelves for electron beam irradiation. Utility Model Content

[0005] The technical problem this invention aims to solve is how to reduce the obstruction of vertical electron beams by the shelving unit.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An electron beam irradiation rack includes a tray and a support frame mounted on the tray to support the product to be irradiated. Both the tray and the support frame are formed with channels through which the electron beam can pass vertically. By providing channels for the electron beam to pass vertically in the tray and support frame, the obstruction of the electron beam by obstacles during emission is reduced, allowing the electron beam to penetrate the product to be irradiated more smoothly. Compared with existing ordinary tray-type racks, this significantly improves the electron beam irradiation efficiency and effectively solves the problem of reduced irradiation efficiency caused by the tray bottom plate obstructing the electron beam in the prior art.

[0008] The channel is formed on the base plate of the tray; the tray also includes a removable cover plate mounted on the base plate for closing the channel and supporting the product to be irradiated. When the product to be irradiated is large enough to be placed on the shelf, the operator can choose to remove the cover plate to reduce obstruction of the electron beam and improve irradiation efficiency; when the product to be irradiated is small enough not to be placed on the shelf, the operator can also use the cover plate to close the channel, thus allowing the shelf to be used as a regular tray.

[0009] The lower surface of the base plate is provided with an anti-slip layer. Because the base plate has channels formed in it, the contact area between this shelf and the conveying device is smaller than that of a regular pallet, resulting in less friction while maintaining the same material and pressure. By adding the anti-slip layer, the coefficient of friction between the base plate and the conveying device is increased, thereby increasing friction and reducing the risk of slippage or displacement. This ensures stable operation of the shelf during conveying and also prevents irradiation position deviation due to shaking, thus improving the reliability of the irradiation process.

[0010] The rack includes a main body and extension racks movably mounted on each side to expand the irradiation area; the combination of the main body and the extension racks is grid-like. The movably mounted extension racks allow for flexible adjustment of the irradiation area according to the size and quantity of the products to be irradiated, improving the rack's versatility and applicability, adapting to the irradiation needs of various product specifications, and optimizing the space utilization of electron beam irradiation. Simultaneously, the grid-like arrangement of the main body and extension racks ensures that the electron beam can irradiate the products without obstruction through the mesh, thereby reducing obstruction and guaranteeing irradiation efficiency.

[0011] The main body and the extension frame are slidably connected laterally, and a locking mechanism is provided between them. The lateral sliding connection makes the extension frame easy to unfold and retract, and allows for quick adjustment of the carrying area; the locking mechanism can firmly lock the extension frame after it is adjusted to a suitable position, preventing displacement of the extension frame during the movement of the shelf, and ensuring the structural stability and reliability of the shelf when carrying the product to be irradiated.

[0012] The extension frame has an upward-folding guard on the side opposite to the main body. The guard effectively prevents the product to be irradiated from slipping off the edge of the extension frame due to inertia, vibration, or other factors during the movement of the shelf, providing good protection, ensuring the safety of the product during the irradiation process, and reducing the risk of product damage or loss.

[0013] The side of the guard facing the main body is provided with a pressing element. The pressing element can apply a certain pressing force to the circumference of the product to be irradiated, so as to fix the product on the carrier and further prevent the product from shaking or shifting during the movement of the carrier, thereby ensuring that the product maintains a good position during the irradiation process and improving the uniformity of the irradiation effect.

[0014] An extended guard is detachably installed on the guard edge, with the top edge of the extended guard being higher than the top edge of the guard edge. This detachable extended guard can be flexibly installed or removed according to the height requirements of the product to be irradiated. When the product is tall, installing the extended guard provides a higher protective height, preventing the product from falling due to exceeding the guard edge height. When not needed, it can be removed without affecting the normal use and spatial layout of the rack, further enhancing the rack's applicability to products of different heights.

[0015] The upper surface of the main body and / or the extension frame is provided with an anti-slip layer. The anti-slip layer on the upper surface can increase the friction between the product to be irradiated and the rack, making the product more stable on the rack and effectively preventing the product from sliding during the movement, turning, or acceleration and deceleration of the rack. This ensures the positional accuracy of the product to be irradiated during the irradiation process and helps to improve the accuracy of irradiation.

[0016] The tray and the shelf are detachably connected. This detachable design facilitates the individual disassembly, installation, repair, or replacement of either the tray or the shelf. If one component is damaged, the entire shelf does not need to be replaced, reducing usage and maintenance costs. Furthermore, when not in use, the shelf can be disassembled for storage, saving space. Moreover, when the product to be irradiated is small and cannot be placed on the shelf, the operator can close the passageway with a cover, allowing the shelf to be used as a regular tray. In this case, the shelf is ineffective and can be removed, reducing obstruction of the electron beam and ensuring irradiation efficiency. Attached Figure Description

[0025] Example

[0026] like Figures 1 to 6 As shown, in this embodiment, the electron beam irradiation rack includes a tray 1 and a support frame 2 mounted on the tray 1 for supporting the product to be irradiated. Both the tray 1 and the support frame 2 are formed with channels 3 through which the electron beam passes vertically. Specifically, both are made of stainless steel (aluminum alloy can also be used in other embodiments). The tray 1 has a rectangular disk-shaped structure. The channels 3 formed on the tray 1 are located at the center of its base plate 11, and the area of ​​the channels 3 accounts for 90% of the area of ​​the base plate 11 (in other embodiments, the proportion can be adjusted according to actual needs, usually in the range of 80%-95%. Within this range, the base plate 11 can provide good support for the cover plate 12 and also provide sufficient penetration area for the electron beam). The support frame 2 is also rectangular, wherein the area of ​​its body 21 is basically equal to that of the tray 1. The support frame 2 is grid-shaped and has several channels 3 (i.e., mesh holes) through which the electron beam passes vertically. This design allows the electron beam to penetrate the product to be irradiated smoothly during the emission process, reducing obstruction from obstacles and significantly improving irradiation efficiency. It effectively solves the problem of reduced irradiation efficiency caused by the tray bottom plate blocking the electron beam in traditional shelving units.

[0027] In this embodiment, the channel 3 is formed on the base plate 11 of the tray 1; the tray 1 also includes a cover plate 12 that is detachably mounted on the base plate 11 to close the channel 3 and support the product to be irradiated. The size of the cover plate 12 is adapted to the base plate 11 of the tray 1, enabling quick installation and removal. When it is necessary to irradiate a large product that can be stably placed on the rack 2, the operator can easily remove the cover plate 12, allowing the electron beam to penetrate the product more smoothly; while for smaller products that cannot be stably placed on the rack 2, the cover plate 12 can be installed on the base plate 11 and used as a regular tray to meet the irradiation needs of different products.

[0028] In this embodiment, the lower surface of the base plate 11 is provided with an anti-slip layer. The anti-slip layer is made of a rubber material with a high coefficient of friction and is firmly attached to the lower surface of the base plate 11 through an adhesive process. Its surface is also provided with dense raised textures to further increase the friction between the anti-slip layer and the conveying device. Even when the shelf is loaded with heavy products and the conveying device's operating speed changes rapidly, the risk of slippage or displacement can be effectively reduced, ensuring stable operation of the shelf during conveying, avoiding irradiation position deviation due to shaking, and guaranteeing the reliability of the irradiation process.

[0029] In this embodiment, the shelf 2 includes a main body 21 and extension shelves 22 movably mounted on each side of the main body 21 to expand the carrying area; the combination of the main body 21 and the extension shelves 22 is grid-like. The main body 21 and the extension shelves 22 are slidably connected laterally, and a locking mechanism 23 is provided between them. The main body 21 is formed by welding six hollow stainless steel square tubes, including two horizontal tubes 211 and four vertical tubes 212, forming a "four" shape. The extension shelves 22 are formed by welding three stainless steel tubes, forming a "U" shape or a "π" shape. There are four extension shelves 22, of which the end sections 224 of two oppositely positioned extension shelves 22 are inserted into the horizontal tubes 211, and the end sections 224 of the other two oppositely positioned extension shelves 22 are inserted into the vertical tubes 212. The extension shelves 22 can extend or retract on the horizontal plane by changing the insertion depth, thereby changing the carrying area. Specifically, the locking mechanism 23 includes five limiting holes 231 spaced along the moving direction of the extension frame 22, formed on the horizontal tube 211 and the vertical tube 212 (which can be adjusted according to actual needs in other embodiments), and spring clips 232 fitted to the limiting holes 231 and installed on the end section 224 of the extension frame 22. The locking of the body 21 and the extension frame 22 is achieved through the cooperation of the limiting holes 231 and the spring clips 232 (the cooperation of the limiting holes 231 and the spring clips 232 is existing technology, commonly used for locking between sections of telescopic umbrella support rods). With the movable extension frame 22, operators can flexibly adjust the carrying area according to the size and quantity of the products to be irradiated, improving the versatility and applicability of the carrying frame, adapting to the irradiation needs of various product specifications, and optimizing the space utilization of the electron beam irradiation production line. Simultaneously, the mesh structure allows the electron beam to irradiate the products to be irradiated without obstruction through the mesh openings, further reducing obstruction to the electron beam and ensuring irradiation efficiency. The lateral sliding connection makes the extension rack 22 easy to unfold and retract, and can quickly adjust the carrying area; the locking mechanism 23 can lock the extension rack 22 firmly after it is adjusted to a suitable position, preventing the extension rack 22 from shifting during the movement of the rack, and ensuring the structural stability and reliability of the rack 2 when carrying the product to be irradiated.

[0030] In this embodiment, the extension frame 22 has an upwardly folded guard edge 221 on the side opposite to the main body 21. An upwardly folded guard edge 221 is welded to the middle section 225 of the extension frame 22. The guard edge 221 effectively prevents the product to be irradiated from slipping off the edge of the extension frame 22 due to inertia, vibration, or other factors during the movement of the shelf, providing good protection, ensuring the safety of the product during irradiation, and reducing the risk of product damage or loss.

[0031] In this embodiment, a pressing member 222 is provided on the side of the retaining edge 221 facing the body 21. The pressing member 222 includes three springs disposed on the side of the retaining edge 221 facing the body 21, and a pressing plate connected to the three springs at the end away from the retaining edge 221. The pressing member 222 on the opposite side can press the product to be irradiated tightly, so that the product is fixed on the carrier 2, further preventing the product from shaking or shifting during the movement of the carrier, thereby ensuring that the product maintains a good position during irradiation and improving the uniformity of the irradiation effect.

[0032] In this embodiment, a raised edge 223 is detachably installed on the guard edge 221, with the top edge of the raised edge 223 higher than the top edge of the guard edge 221. Specifically, two rows of screws are vertically fixed on the guard edge 221. The raised edge 223 is plate-shaped and has mounting holes adapted to the screws. When the screws are inserted into the mounting holes and tightened with nuts, the raised edge 223 is fixed to the guard edge 221. The detachable raised edge 223 can be flexibly installed or removed according to the height requirements of the product to be irradiated. When the product is tall, installing the raised edge 223 can provide a higher protective height, preventing the product from falling due to exceeding the height of the guard edge 221. When not needed, it can be removed without affecting the normal use and spatial layout of the rack, further enhancing the applicability of the rack to products of different heights and meeting diverse product irradiation needs.

[0033] In this embodiment, the upper surface of the main body 21 and / or the extension frame 22 is provided with an anti-slip layer. The anti-slip layer on the upper surface can increase the friction between the product to be irradiated and the carrier, making the product more stable on the carrier and effectively preventing the product from sliding during the movement, turning, or acceleration and deceleration of the carrier. This ensures the positional accuracy of the product to be irradiated during the irradiation process, helps to improve the accuracy of irradiation, ensures that the electron beam can accurately act on the predetermined part of the product, and improves the irradiation effect.

[0034] In this embodiment, the tray 1 and the shelf 2 are detachably connected. Four clips 213 are provided at the bottom of the main body 21, which are detachably engaged with the side wall of the tray 1 for positioning. This detachable design facilitates the individual disassembly, installation, repair, or replacement of either the tray 1 or the shelf 2. If one component is damaged, the entire shelf does not need to be replaced, reducing usage and maintenance costs. Furthermore, when not in use, the shelf can be disassembled for storage, saving storage space. Additionally, when the product to be irradiated is small and cannot be placed on the shelf 2, the operator can use the cover plate 12 to close the channel 3, using the shelf as a regular tray. In this case, the shelf 2 can be removed, reducing its obstruction of the electron beam and thus ensuring irradiation efficiency, while improving the shelf's flexibility and practicality.
