Description

Technical Field

[0001] This utility model belongs to the field of storage container technology, specifically a vertical container for collecting and storing uranium hexafluoride. Background Technology

[0002] In uranium enrichment systems, natural uranium hexafluoride (UF6) is used as a raw material, based on 238 U、 234 U、 235 U isotope mass differences are addressed by using isotope separation technology to achieve physical separation. 235 The U isotope is gradually enriched, ultimately producing enriched uranium that meets application standards, while simultaneously separating depleted uranium tailings. Enriched uranium requires condensation and collection using uranium hexafluoride containers. Specifically, the container is placed in a cryogenic environment, and gaseous uranium hexafluoride is injected into it. Upon contact with the cryogenic container, the gaseous uranium hexafluoride liquefies, forming liquid uranium hexafluoride, which is then condensed, collected, and stored. However, the uranium hexafluoride only contacts the inner wall of the container. Uranium hexafluoride near the inner wall is preferentially condensed and collected, while uranium hexafluoride in the middle diffuses outwards and condenses again upon contact with the inner wall, resulting in low collection efficiency. Furthermore, the containers are typically placed horizontally, leading to a large footprint. Utility Model Content

[0003] To address the problems mentioned above, this invention provides a vertical container for collecting and storing uranium hexafluoride. A partition is provided on the inner wall of the vertical cylinder, which increases the condensation contact area between gaseous uranium hexafluoride and the vertical cylinder. This allows for the condensation and collection of gaseous uranium hexafluoride in all parts of the vertical cylinder, improving the collection efficiency. Simultaneously, the vertical cylinder reduces the container's footprint, facilitating centralized, batch storage.

[0004] This utility model provides a vertical container for collecting and storing uranium hexafluoride, including a vertically placed vertical cylinder. Both the upper and lower ends of the vertical cylinder are fixed with end caps. The vertical cylinder and the two end caps together form a sealed cavity. A material inlet pipe for injecting uranium hexafluoride is connected to the upper end cap. A sealing component for sealing the material inlet pipe is provided on the material inlet pipe. Multiple cylinder partitions are fixedly connected to the inner wall of the vertical cylinder. The multiple cylinder partitions are arranged circumferentially.

[0005] Furthermore, multiple head partitions are fixedly connected to the inner wall of the lower end head, and the multiple head partitions are arranged circumferentially.

[0006] Furthermore, multiple supports are fixedly connected to the bottom surface of the lower end cap, and the multiple supports are arranged circumferentially.

[0007] Furthermore, multiple lifting lugs are fixedly connected to the outer wall of the upper end cap, and the multiple lifting lugs are arranged circumferentially.

[0008] Furthermore, the sealing assembly includes a concave flange and a convex blind flange. The concave flange is fixedly connected to the outer wall of the material inlet pipe, and the convex blind flange is inserted into the concave flange. The convex blind flange and the concave flange are fixedly connected by studs and nuts, and a gasket is provided between the convex blind flange and the concave flange.

[0009] Furthermore, a right-angle valve is installed on the upper end cap, and an insertion tube is connected to the right-angle valve. The insertion tube extends downward from the inside of the vertical cylinder to the lower end cap.

[0010] Furthermore, the right-angle valve is provided with a protective cover, which includes a protective housing and an operating door. The protective housing is fixedly connected to the outer wall of the upper end cap and covers the right-angle valve. One end of the operating door is hinged to the outer wall of the upper end cap, and the other end of the operating door is connected to the protective housing through a locking assembly.

[0011] Furthermore, the locking assembly includes a locking rod, a vertically oriented groove inside the operating door, the locking rod sliding vertically within the groove, a spring between the locking rod and the bottom wall of the groove, a locking hole inside the protective housing, the top of the locking rod extending upward through the operating door and inserted into the locking hole, a limit groove on the side of the operating door away from the right-angle valve, and an operating rod fixedly connected to the locking rod, the operating rod sliding vertically within the limit groove.

At the same time, the vertical cylindrical body 1 reduces the footprint of the container, which is convenient for batch centralized storage.

[0026] Multiple head baffles 6 are fixedly connected to the inner wall of the lower end head 2. The multiple head baffles 6 are arranged circumferentially. The head baffles 6 can further increase the condensation contact area between gaseous uranium hexafluoride and the vertical cylinder 1, and further improve the collection efficiency of uranium hexafluoride.

[0027] Multiple supports 7 are fixedly connected to the bottom surface of the lower end cap 2. The multiple supports 7 are arranged circumferentially. The support 1 is a support type support, which is welded to the lower end cap 2. The support type support has a compact structure, which is convenient for the centralized storage of large quantities of containers and saves floor space.

[0028] Multiple lifting lugs 8 are fixedly connected to the outer wall of the upper end cap 2. The multiple lifting lugs 8 are arranged circumferentially, which facilitates the lifting of the container and makes it easy to move the container.

[0029] The sealing assembly 4 includes a concave flange 41 and a convex blind flange 42. The concave flange 41 is fixedly connected to the outer wall of the material inlet pipe 3, and the convex blind flange 42 is inserted into the concave flange 41. The convex blind flange 42 and the concave flange 41 are fixedly connected by studs 43 and nuts 44. A gasket 45 is provided between the convex blind flange 42 and the concave flange 41. This application uses the convex blind flange 42 to seal the material inlet pipe 3, which has a simple and reliable structure and improves the reliability of long-term material storage in the container. At the same time, the gasket 45 can further seal the gap between the concave flange 41 and the convex blind flange 42, improving the airtightness of the container.

[0030] A right-angle valve 9 is installed on the upper end cap 2, and an insertion tube 10 is connected to the right-angle valve 9.

[0033] The protective cover 11 protects the right-angle valve 9 from impact and rainwater corrosion. When the right-angle valve 9 needs to be used to extract materials, the operating lever 126 is pulled down. The operating lever 126 moves the locking lever 121 downward. When the locking lever 121 disengages from the locking hole 124, the operating door 112 can be opened, and materials can be extracted through the right-angle valve 9. After the operation is completed, the operating door 112 is closed. When the locking lever 121 is aligned with the locking hole 124, the operating lever 126 is released. The spring 123 pushes the locking lever 121 upward so that the locking lever 121 is inserted into the locking hole 124, thereby locking the operating door 112.
