Description

Technical Field

[0001] This utility model belongs to the field of storage container technology, specifically a 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. After liquefaction and homogenization, it is then packaged. Specifically, the container is placed in a cryogenic environment, and gaseous uranium hexafluoride is injected into the container. Upon contact with the cryogenic container, the gaseous uranium hexafluoride liquefies, forming liquid uranium hexafluoride, which is then collected and stored. However, the uranium hexafluoride only contacts the inner wall of the container. Uranium hexafluoride near the inner wall is preferentially collected and condensed, while the uranium hexafluoride in the middle diffuses outwards and is collected again upon contact with the inner wall. This results in low collection efficiency for uranium hexafluoride. Utility Model Content

[0003] To address the problems mentioned above, this invention provides a container for collecting and storing uranium hexafluoride. A condensation baffle is provided on the inner wall of the cylinder. The condensation baffle increases the condensation contact area between gaseous uranium hexafluoride and the cylinder, enabling the condensation and collection of gaseous uranium hexafluoride in all parts of the cylinder, thereby improving the collection efficiency of uranium hexafluoride.

[0004] This utility model provides a container for collecting and storing uranium hexafluoride, including a cylindrical body with end caps fixed at both ends.

[0028] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The following is in conjunction with the appendix Figure 1 To be continued Figure 10 The present invention will be described in detail with specific embodiments.

[0030] Example 1

[0031] Reference Figures 1-5 The container for collecting and storing uranium hexafluoride provided in this embodiment includes a horizontal cylindrical body 1. Both ends of the cylindrical body 1 are fixedly connected to end caps 2. The cylindrical body 1 and the two end caps 2 together form a sealed cavity. A skirt seat 3 is fixedly connected to the outer wall of the end cap 2. A first valve 4 for injecting uranium hexafluoride is installed on the upper part of one end cap 2, and a plug 5 for draining is provided on the lower part of the other end cap 2. A condensation baffle 6 is provided on the inner wall of the cylindrical body 1.

[0032] The condensation baffle 6 includes multiple long baffles 60 and multiple support ring plates 61 with central openings. The long baffles 60 are fixed to the inner wall of the cylinder 1 along the axial direction of the cylinder 1, and the multiple long baffles 60 are arranged in a circumferential array. The support ring plates 61 are fixed to the ends of the long baffles 60 away from the inner wall of the cylinder 1. One support ring plate 61 is simultaneously fixedly connected to multiple long baffles 60. The multiple support ring plates 61 are arranged along the axial direction of the cylinder 1 and also have a supporting function, which can improve the overall structural stability of the condensation baffle 6. In this embodiment, eight long baffles 60 and two support ring plates 61 are provided, but the present invention does not specifically limit the number of long baffles 60 and support ring plates 61. The condensation baffle 6 can increase the condensation contact area between gaseous uranium hexafluoride and the cylinder 1, so that gaseous uranium hexafluoride in all parts of the cylinder 1 can be condensed and collected, thereby improving the collection efficiency of uranium hexafluoride.

[0033] A second valve 7 for discharging liquid uranium hexafluoride is installed at the lower part of the end cap 2, which is equipped with a first valve 4. A hose 70 is connected to the second valve 7, extending into the cylinder 1 and located at the bottom of the cylinder 1. The second valve 7 facilitates the discharge of liquid uranium hexafluoride, thereby facilitating subsequent dispensing. Furthermore, the second valve 7 ensures the sealing performance inside the cylinder 1 while also being compatible with subsequent process systems. The hose 70 allows for the discharge of liquid uranium hexafluoride from the bottom of the cylinder 1, ensuring a more thorough discharge.

[0034] Both the first valve 4 and the second valve 7 are equipped with protective covers 8. The protective cover 8 includes a curved plate 80, a cover plate 81, and two side plates 82. The cover plate 81 is fixed to the top of the curved plate 80, and the two side plates 82 are fixed to both sides of the curved plate 80. The cover plate 81 is bolted to the skirt base 3. The protective cover 8 protects the first valve 4 and the second valve 7 from damage by external forces, extending their service life. Furthermore, the protective cover 8 is detachable for easy operation of the first valve 4 and the second valve 7.

[0035] Example 2

[0036] Reference Figures 6-8 The difference between this embodiment and Embodiment 1 is that the condensation baffle 6 includes multiple sets of circular baffles 62. These sets of circular baffles 62 are arranged along the axial direction of the cylinder 1 and fixed to the inner wall of the cylinder 1. Each set of circular baffles 62 includes two circular baffles 62 with different opening shapes. One circular baffle 62 has a central hole 63 at its center, and the other circular baffle 62 has four central holes 63 at its center. The two circular baffles 62 are arranged alternately. In this embodiment, there are 23 sets of circular baffles 62, but the present invention does not specifically limit the number of circular baffles 62. The central holes 63 ensure the flow of gaseous uranium hexafluoride in all parts of the cylinder 1. Furthermore, the staggered arrangement of the central holes 63 allows gaseous uranium hexafluoride to fully accumulate in different zones within the cylinder 1, greatly increasing the condensation contact area and improving the condensation collection efficiency.

[0037] Example 3

[0038] Reference Figure 9 The difference between this embodiment and embodiment 1 is that the protective cover 8 includes a curved plate 80, a cover plate 81, and two side plates 82. The cover plate 81 is fixed to the top of the curved plate 80, and the two side plates 82 are fixed to both sides of the curved plate 80. The bottom of the curved plate 80 is hinged to the outer wall of the end cap 2 via a hinge 12. A locking assembly 9 is provided on the cover plate 81. The locking assembly 9 includes a support frame 90, which is fixed to the cover plate 81. A locking rod 91 is vertically slidably connected between the support frame 90 and the cover plate 81. A pull ring 92 is fixedly connected to the top of the locking rod 91. A locking hole 93 is provided on the skirt 3. The bottom of the locking rod 91 is inserted into the locking hole 93. A fixing ring 94 is fixedly connected to the locking rod 91. A spring 95 is provided between the fixing ring 94 and the support frame 90. The locking rod 91 passes through the inside of the spring 95. The fixing ring 94 abuts against the cover plate 81 under the elastic action of the spring 95.

[0039] When the protective cover 8 needs to be opened to operate the valve, pull the pull ring 92 upward. The pull ring 92 drives the locking rod 91 to move upward. The locking rod 91 drives the fixing ring 94 to move upward. The fixing ring 94 compresses the spring 95. When the locking rod 91 disengages from the locking hole 93, the protective cover 8 can be rotated downward to open the protective cover 8. After the operation is completed, rotate the protective cover 8 upward. When the locking rod 91 is aligned with the locking hole 93, release the pull ring 92. The locking rod 91 moves downward under the elastic action of the spring 95. The locking rod 91 is inserted into the locking hole 93, thus completing the closing of the protective cover 8. The locking component 9 makes the opening and closing of the protective cover 8 faster and more convenient.

[0040] Example 4

[0041] Reference Figure 10 The difference between this embodiment and Embodiment 1 is that a flange connector 10 for discharging liquid uranium hexafluoride is installed at the lower part of the end cap 2, which is equipped with the first valve 4. The end of the flange connector 10 away from the end cap 2 is connected to a flange plug 11 by bolts. The flange connector 10 also serves to facilitate the discharge of liquid uranium hexafluoride and can also be adapted to subsequent process systems. The flange plug 11 seals the flange connector 10 to ensure the airtightness of the cylinder 1.

However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
