Description

Technical Field

[0001] The utility model relates to the field of food and medicine packaging machinery, in particular to a radioactive shielding chamber material transfer device. Background Art

[0002] Currently, the transfer of radioactive materials between production areas is primarily carried out using mechanical carts. The process involves placing the radioactive material into a shielded lead drum, which is then hoisted onto a cart using a sling. The cart then transports the radioactive source to the vicinity of the production isolation equipment, where it is then docked with the isolation equipment via a material transfer drawer for transfer. Because iodine-based radioisotopes generate volatile aerosols during production, any aerosol leakage during transport could contaminate the transported material and expose personnel to radioactive aerosols. However, the heavy lead cover on the drum is unsuitable for RTP valves (the components used to transfer sterile, high-risk materials between sterile environments). Utility Model Content

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Figures 1 to 6 An embodiment of a radioactive shielding chamber material transfer device of the present invention is shown. The radioactive shielding chamber material transfer device of this embodiment includes a shielding container 11, a container sealing cover 12, a transfer cart 6, and a base 3, a shielding cover 4 and a guide member 21 for providing guidance for the transfer cart 6, which are arranged on the shielding chamber 2. The base 3 is provided with a transfer channel 31, the shielding cover 4 is provided with a sealing portion 41 for blocking the transfer channel 31, the base 3 is provided with a first sealing member 32 for sealing the gap between the base 3 and the sealing portion 41 and a second sealing member 33 for sealing the gap between the base 3 and the shielding container 11, the container sealing cover 12 is provided with a first connecting portion 121, the shielding container 11 is provided with a second connecting portion 111 detachably connected to the first connecting portion 121, and the sealing portion 41 is provided with a third connecting portion 411 detachably connected to the first connecting portion 121. Among them, the shielding container 11 can be, for example, a lead barrel or other container with radioactive shielding function; the guide member 21 can be, for example, a guide block or a guide rail; the first connecting part 121, the second connecting part 111, and the third connecting part 411 can be structures such as locks, snaps, lock grooves or threads, which can ensure sealing and facilitate automatic connection and separation by rotation.

[0030] The radioactive shielding chamber material transfer device of this embodiment is specifically as follows Figure 2As shown, in the initial state, the shielding container 11 and the container sealing cover 12 are connected through the second connecting part 111 and the first connecting part 121, so that the shielding container 11 is kept in a sealed state. The gap between the base 3 and the sealing part 41 is sealed by the first sealing member 32, so that the shielding chamber 2 is kept in a sealed state; specifically, as Figure 1 shown, when it is necessary to transfer radioactive materials between the shielding container 11 and the shielding chamber 2, the guiding member 21 provides a guiding function for the transfer trolley 6, so that the transfer trolley 6 transfers the shielding container 11 into place. The second sealing member 33 seals the gap between the base 3 and the shielding container 11 to avoid leakage during subsequent transfer (specifically, as Figure 5 shown), specifically refer to Figure 3 and Figure 4 . The container sealing cover 12 is separated from the shielding container 11, and then the container sealing cover 12 and the sealing part 41 are connected through the first connecting part 121 and the third connecting part 411. Finally, the shielding cover 4 is opened, and the sealing part 41 and the container sealing cover 12 move with the shielding cover 4. At this time, radioactive materials can be transferred between the shielding container 11 and the shielding chamber 2 through the transfer channel 31 (for example, transferred by a manipulator in the shielding chamber 2); after the material transfer is completed, the shielding cover 4 is closed, the container sealing cover 12 is separated from the sealing part 41 and reconnected to the shielding container 11, and then the transfer trolley 6 can transfer the shielding container 11. The structure is simple and reliable, which is beneficial to reducing the leakage risk during the transfer process and ensuring the safety of operators.

[0031] Furthermore, in this embodiment, the base 3 is provided with a fourth connecting part 34 for detachably connecting with the shielding container 11. Among them, the fourth connecting part 34 can be, for example, a flange, a buckle and other structures. After the shielding container 11 is fixed on the base 3 through the fourth connecting part 34, the transfer trolley 6 can be separated from the shielding container 11 and perform other transfer work, which is more convenient and flexible to use.

[0032] As a preferred embodiment, both the first sealing member 32 and the second sealing member 33 are pneumatic sealing rings. After inflation, the pneumatic sealing rings can ensure a reliable seal between the base 3 and the sealing portion 41, and between the base 3 and the shielding container 11. Before the shielding container 11 and the sealing portion 41 need to move relative to the pneumatic sealing rings (for example, when the shielding container 11 is raised or lowered, rotated, or when the sealing portion 41 is flipped up and down), the pneumatic sealing rings can be deflated and contracted, thereby creating a gap between the shielding container 11 and the sealing portion 41. This prevents friction and particle generation, reduces wear, and extends the service life, resulting in a reasonable and effective structure. Of course, before the first sealing member 32 is deflated, it is necessary to ensure that the second sealing member 33 is in an inflated and sealed state. Similarly, before the second sealing member 33 is deflated, it is also necessary to ensure that the first sealing member 32 is in an inflated and sealed state to prevent leakage. Of course, in other embodiments, the first and second sealing members 32 and 33 can also be conventional sealing rings, sealing strips, etc., but the performance is inferior to that of pneumatic sealing rings.

[0033] Furthermore, in this embodiment, the shielding cover 4 is hingedly connected to the base 3, and the base 3 is also provided with an opening and closing drive mechanism 5 for driving the shielding cover 4 to flip. That is, the shielding cover 4 opens and closes by flipping up and down, which is simple and compact in structure and occupies little space within the shielding chamber 2. Of course, in other embodiments, the shielding cover 4 can also be opened and closed by lifting or lifting combined with translation, but this structure is more complex, occupies a large space, and may also hinder the passage of radioactive materials through the transfer channel 31.

[0034] See Figure 4 and Figure 5 Furthermore, in this embodiment, the opening and closing drive mechanism 5 includes a servo motor 51, a transmission gear set 52, and an opening and closing gear 53 disposed on the hinge axis of the shielding cover 4. The output shaft of the servo motor 51 is connected to the transmission gear set 52, and the opening and closing gear 53 meshes with the transmission gear set 52. The forward and reverse rotation of the servo motor 51 drives the opening and closing gear 53 through the transmission gear set 52, thereby driving the shielding cover 4 to flip up and down. This structure is simple and the transmission is reliable.

[0035] Furthermore, in this embodiment, the shielding container 11 and the container sealing cover 12 are positioned by a tapered surface, and a third sealing member 13 is provided on the tapered surface. This tapered positioning facilitates accurate docking of the container sealing cover 12 with the shielding container 11 and helps tighten the third sealing member 13, improving the seal between the two. This structure is rational and effective. The third sealing member 13 may be, for example, a sealing ring or a sealing strip.

[0036] Further, in this embodiment, the container sealing cover 12 is made of stainless steel. The container sealing cover 12 made of stainless steel can be applicable to various types of radioactive materials, and at the same time is lighter in weight than a lead cover, which is convenient for docking with and separating from the sealing part 41 and for flipping up and down with the sealing part 41.

[0037] As a preferred embodiment, the base 3 is provided below the shielding chamber 2. The transfer trolley 6 is provided with a lifting mechanism 64 for driving the shielding container 11 to lift, a translation mechanism 65 for driving the shielding container 11 to translate, and a rotation mechanism 66 for driving the shielding container 11 to rotate. The base 3 is provided below the shielding chamber 2, which is convenient for the shielding container 11 to be docked with the shielding chamber 2 in an upright state to realize the transfer of materials. At the same time, it is beneficial to prevent pollutants from entering the interior of the shielding chamber 2, thereby ensuring the clean environment inside the shielding chamber 2. For details, see Figure 6 , the translation mechanism 65 can drive the shielding container 11 to move between the top shielding member 61 and the base 3, the lifting mechanism 64 can drive the shielding container 11 to dock with or separate from the top shielding member 61 and the base 3, and the rotation mechanism 66 drives the shielding container 11 to rotate, so that the container sealing cover 12 is separated from the shielding container 11 and connected to the sealing part 41 to open the container sealing cover 12, or the container sealing cover 12 is separated from the sealing part 41 and reconnected to the shielding container 11. Preferably, the translation mechanism 65 includes a translation guide rail and a translation driving member (such as a cylinder, a lead screw nut pair or a synchronous belt, etc.). The lifting mechanism 64 is arranged on the translation guide rail and can reciprocate along the translation guide rail under the action of the translation driving member; the lifting mechanism 64 includes a base arranged on the translation guide rail, multiple lifting lead screws are arranged on the base, the lifting platform is arranged on the lifting lead screws through a nut seat, and the lifting lead screws are driven to rotate by components such as a motor and a bevel gear pair. As the lifting lead screws rotate, the lifting of the lifting platform is realized; the rotation mechanism 66 is arranged on the lifting platform. The rotation mechanism 66 can include a rotating seat and a rotation driving member, and the rotation driving member drives the rotating seat to rotate through a transmission structure such as a gear pair, with a reasonable and effective structure. Of course, in other embodiments, the lifting mechanism 64, the translation mechanism 65 and the rotation mechanism 66 can also be in other forms, and the connection relationship between the three can also be adjusted. For example, the lifting mechanism 64 is arranged on the rotation mechanism 66, the lifting mechanism 64 directly drives the shielding container 11 to lift, and the rotation mechanism 66 drives the lifting mechanism 64 and the shielding container 11 to rotate as a whole. The specific structure will not be elaborated here.

[0038] Furthermore, in this embodiment, the transfer trolley 6 is provided with a top shielding member 61 for docking with the top of the shielding container 11. Since the container sealing cover 12 is made of stainless steel and has a weak radioactive shielding ability, the top shielding member 61 is arranged on the transfer trolley 6, which is beneficial to improving the radioactive shielding ability of the top of the shielding container 11 and further enhancing the reliability.

[0039] Furthermore, in this embodiment, a handle 62 is provided on the transfer trolley 6, and a side shield 63 is provided between the handle 62 and the top shield 61. When an operator operates the transfer trolley 6, the side shield 63 can additionally form a shielding layer between the shielding container 11 and the operator, further enhancing safety and reliability. Among them, the top shield 61 and the side shield 63 can be, for example, lead plates, etc.
