Description

Technical Field

[0001] This utility model relates to a shielded feeding and discharging production mechanism. Background Technology

[0002] The production process of radiopharmaceuticals generates a large amount of ionizing radiation, especially when the raw materials for radiopharmaceuticals are produced.

[0003] Currently, radiopharmaceuticals are transported through sealed shielded containers, which are manually opened to retrieve the materials before being transferred to the production hot chamber. Since radiation sources are continuously released when the container is opened, even with protective gear, comprehensive protection is not possible. Furthermore, the shielded containers are generally made of high-density heavy metals such as lead, making them significantly heavy, inconvenient to operate, and a waste of a lot of manpower.

[0004] Therefore, a shielded feeding and discharging production mechanism is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-6 As shown, a shielded feeding and discharging production mechanism includes a tank tray 12, a first mounting plate 14, a lifting drive assembly, and a lid removal assembly; it also includes a feeding chamber 1, which is disposed within a production hot chamber 3; the first mounting plate 14 is disposed within the feeding chamber 1, with the tank tray 12 at one end of the first mounting plate 14, a lead can 4 disposed on the tank tray 12, and a lead can lid 5 disposed at the port of the lead can 4; the lifting drive assembly is disposed on the left side of the inner wall of the feeding chamber 1 and connected to the tank tray 12, for pushing the lead can 4 upward for discharging; a lid removal assembly for removing the lead can lid 5 is disposed at the end of the first mounting plate 14 away from the tank tray 12. A U-shaped limiting block 13 for limiting the tank tray 12 is connected to the left end of the first mounting plate 14.

[0020] Specifically, the feeding chamber 1 is provided with a feeding connection channel 2 that connects to the production hot chamber 3, and the feeding connection channel 2 is located directly above the lead tank body 4.

[0021] Specifically, the lifting drive assembly includes a lifting cylinder 8, which is located on the left side of the inner wall of the feeding chamber 1. The moving end of the lifting cylinder 8 is connected to the tank tray 12 through the lifting bracket 11.

[0022] Specifically, the lifting drive assembly also includes a guide shaft 10, which is located on the left side of the inner wall of the feeding chamber 1. A linear bearing 9 is slidably connected to the guide shaft 10, and the outer wall of the linear bearing 9 is connected to the moving end of the lifting cylinder 8. The moving end of the lifting cylinder 8 drives the lifting bracket 11 and the tank tray 12, as well as the lead tank 4 on the tank tray 12, to rise and discharge above the feeding connection channel 2.

[0023] Specifically, a handle 15 is installed on the side wall of the first mounting plate 14 to enable horizontal pushing and pulling movements, facilitating maintenance and adjustment.

[0024] Specifically, it also includes a mounting base plate 7, which is connected to the bottom surface of the feeding chamber 1, and the upper surface of the mounting base plate 7 is connected to the first mounting plate 14 through multiple support columns 6.

[0025] Specifically, the cap-removing assembly includes a slot plate 22 connected to the output end of a first cylinder 19, which is fixedly connected to a second mounting plate 20. It also includes a second cylinder 17 connected to the lower end face of the first mounting plate 14, with its moving end connected to the second mounting plate 20 via a connecting plate 18. A drawer-type slide rail 16 is provided on the lower end face of the first mounting plate 14, and the moving end of the second cylinder 17 is slidably connected to the drawer-type slide rail 16 via a slider. Furthermore, it includes a pulley 21 connected to the lower end face of the second mounting plate 20, which is rolletably connected to the upper end face of the first mounting plate 14. The pulley 21 reduces friction, making the overall movement smoother and more stable.

[0026] Specifically, when removing the lid, cylinder 17 drives cylinder 19 and the slot plate 22 to move to the left, so that the slot plate 22 contacts the lead can lid 5. Then, cylinder 19 extends upward, causing the slot plate 22 to move the lead can lid 5 upward away from the lead can body 4. Then, cylinder 17 drives cylinder 19 and the slot plate 22 to move to the right back to the initial position to avoid interference when the lead can body 4 rises. After the lead can body 4 rises and discharges and resets, cylinder 17 drives cylinder 19 and the slot plate 22 to move to the left, so that the slot plate 22 is above the lead can body 4. Then, the output end of cylinder 19 descends, placing the lead can lid 5 on the lead can body 4. Then, cylinder 17 drives cylinder 19 and the slot plate 22 to move to the right back to the initial position.

[0027] This shielded material handling production mechanism, through the installation of lifting drive components and lid-removing components, enables the tank to move up and down, automatically open and move the lid. It achieves automatic lid opening without opening the shielded door, preventing the exposure of radioactive sources to the outside environment during production, ensuring personnel safety. Furthermore, due to the weight of the protective lead tank, the automated mechanism significantly reduces human error and frees up labor. The mechanism has a simple structure and smooth movement. Some components have been redesigned to be non-standard, replacing some large standard parts, reducing overall space and manufacturing costs, and modularizing the overall structure for easy installation and maintenance. Simultaneously, it operates automatically after the door is closed, ensuring the same environmental level between the chamber and the production hot chamber.
