Description

Technical Field

[0001] This invention relates to the field of container cleaning technology, and more specifically to a cleaning structure. Background Technology

[0002] Uranium hexafluoride (UF6) is a fundamental nuclear material widely used in uranium enrichment and handling. With the rapid development of the nuclear power industry, UF6 production has increased year by year, leading to a rapid increase in the usage and processing volume of UF6 containers. UF6 containers are generally sealed, hollow containers with a right-angle valve and a plug at each end serving as the container's inlet.

[0003] According to industry standards, uranium hexafluoride containers must be cleaned and inspected when any of the following situations occur: "regular inspection and testing of containers; excessive residual amount in empty containers; change in the type (abundance) of container filling material; container maintenance; excessively high radiation dose rate on the container surface". Containers that pass the inspection can be reused, while those that fail are scrapped and temporarily stored.

[0004] The cleaning process for uranium hexafluoride containers requires a comprehensive inspection of the internal surfaces (inner walls). According to industry standards, the interior of the container should be clean, dry, and free of any contaminants. Visible surfaces such as valve passages should not have any corrosion marks, green spots, sediment, moisture, scratches, or white alkaline substances.

[0005] Currently, the cleaning of uranium hexafluoride containers employs a chemical reagent transfer cleaning method. The container is fixed on a large, rotating cleaning fixture, and cleaning liquid is injected into the container for transfer cleaning. The specific process flow is as follows: "Container weighing—hydrolysis (production water)—alkaline washing (a mixture of 5% sodium carbonate solution or 5% potassium carbonate solution and 27.5% or higher hydrogen peroxide)—water washing (production water)—rust removal (4.5%~10% oxalic acid solution)—hydraulic pressure test—blowing—baking—vacuum measurement."

[0006] While the above-described process for cleaning uranium hexafluoride containers can achieve satisfactory and comprehensive cleaning of the container's internal surface, it requires approximately three times the container's volume in water. Furthermore, the relatively low impact force of rotating water results in poor removal of scale-laden contaminants. The cleanliness of the uranium hexafluoride containers directly impacts the purity of the uranium hexafluoride feed, and the waste liquid generated from container cleaning accounts for approximately 80% of the total waste liquid from uranium enrichment plants. Treating uranium-containing waste liquid requires significant energy and financial investment and poses serious environmental risks.

[0007] In summary, existing cleaning methods for uranium hexafluoride containers are insufficient to meet practical application requirements in terms of improving cleaning efficiency and reducing the generation of cleaning waste liquid.

[0008] Therefore, existing technologies need further development. Summary of the Invention

[0009] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a cleaning structure to solve the technical problem of low cleaning efficiency in related technologies.

[0010] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: A cleaning structure is provided, comprising: a light source assembly for emitting a cleaning beam into the interior of a container to clean the inner wall of the container; a telescopic assembly having a communicating cavity for the cleaning beam to pass through, and an inlet for the cleaning beam to enter the communicating cavity at the end of the telescopic assembly; the telescopic assembly having an outlet spaced apart from the inlet; the outlet being adjustablely positioned inside the container; and a scanning component disposed within the telescopic assembly, corresponding to the outlet, so that the cleaning beam entering the communicating cavity is reflected by the scanning component and emitted from the outlet; the scanning component being movably disposed.

The drive slider is movably connected to the scanning head and has a connecting hole inside. The connecting hole has an internal thread that mates with the external thread, so that the drive slider can be moved by rotating the drive shaft.

[0015] Furthermore, the drive unit is a rod-shaped structure, which passes through the fixed base. One end of the drive unit abuts against the scanning component, and the other end of the drive unit abuts against the drive slider.

[0016] Furthermore, the drive slider includes a connecting surface that abuts against the drive unit, and the connecting surface and the rotation axis of the drive shaft have a preset angle, which is an acute angle.

[0017] Furthermore, the cleaning structure also includes an elastic element located on the side of the drive unit away from the rotation axis. One end of the elastic element is connected to the scanning component, and the other end of the elastic element is connected to the fixed base.

[0018] Furthermore, the cleaning structure also includes: a lens component for imaging, which is disposed on the inner wall of the second communicating cavity; and an illumination component for emitting light, which is disposed on the inner wall of the second communicating cavity and is disposed opposite to the lens component.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] According to an embodiment of the present invention, a cleaning structure is provided; please refer to [link / reference]. Figures 1 to 7 The system includes: a light source assembly 1 for emitting a cleaning beam 20 into the interior of the container 10 for cleaning the inner wall of the container 10; a telescopic assembly 2 having a communicating cavity 21 through which the cleaning beam 20 passes, and an inlet 22 at the end of the telescopic assembly 2 for the cleaning beam 20 to enter the communicating cavity 21; the telescopic assembly 2 having an outlet 23 spaced apart from the inlet 22; the outlet 23 being adjustablely positioned inside the container 10; and a scanning component 3 disposed within the telescopic assembly 2, corresponding to the outlet 23, so that the cleaning beam 20 entering the communicating cavity 21 is reflected by the scanning component 3 and emitted from the outlet 23; the scanning component 3 being movably disposed.

[0033] In an embodiment of the present invention, the light source assembly 1 emits a cleaning beam 20 towards the inner wall of the container 10. The cleaning beam 20 enters from the inlet 22 of the telescopic assembly 2, passes through the communicating cavity 21, and is reflected by the scanning component 3 before exiting from the outlet 23. The movement of the scanning component 3 achieves cleaning of the scanning area of ​​the inner wall of the container 10. Compared with traditional cleaning methods for uranium hexafluoride containers, the cleaning structure of the present invention is simple to operate, has a strong ability to remove scaled contaminants, and achieves fast cleaning efficiency. The cleaning structure of the present invention solves the technical problem of low cleaning efficiency in related technologies.

[0034] See Figure 1In the cleaning structure of this embodiment, the telescopic component 2 includes: a light guide rod 24, which passes through the first container opening 101 of the container 10, and an inlet 22 is disposed on the light guide rod 24; a scanning head 25, which is connected to the light guide rod 24; and an outlet 23, which is disposed on the scanning head 25. The connecting cavity 21 includes a first connecting cavity 211 located within the light guide rod 24 and a second connecting cavity 212 located within the scanning head 25. The scanning component 3 is rotatably disposed within the second connecting cavity 212. The cleaning beam 20 enters from the inlet 22, passes through the first connecting cavity 211 within the light guide rod 24, reaches the scanning component 3 in the second connecting cavity 212, and after reflection by the scanning component 3, exits from the outlet to the inner wall of the container 10, completing the cleaning process. The scanning component 3 is relatively movable within the second connecting cavity 212, and the movement of the scanning component 3 changes the reflection angle to clean the inner walls of other areas.

[0035] See Figure 1 In the cleaning structure of this embodiment, both the light guide rod 24 and the scanning head 25 are cylindrical structures; the maximum outer diameter of the light guide rod 24 is smaller than the maximum outer diameter of the scanning head 25. The cylindrical structure of the light guide rod 24 matches the shape of the first container opening 101 of the container 10, and the cylindrical light guide rod 24 is more convenient to rotate in the first container opening 101 after it extends into the container 10; the cylindrical structure of the scanning head 25 provides space for the relative movement of the scanning component 3, making its movement within the second communicating cavity 212 more flexible.

[0036] See Figure 2 In the cleaning structure of this embodiment, the second communicating cavity 212 is provided with: a rotating shaft 41, the scanning component 3 being rotatably connected to the rotating shaft 41; a fixed base 42, fixedly connected to the scanning head 25, the rotating shaft 41 being mounted on the fixed base 42; and a driving unit 43, movably disposed, the driving unit 43 being used to abut against the scanning component 3 to drive the scanning component 3 to rotate. The scanning component 3 is rotatable relative to the rotating shaft 41, the rotating shaft 41 being mounted on the fixed base 42, and the driving unit 43 abutting against the scanning component 3. When the driving unit 43 is operated to move, the scanning component 3 abutting against the driving unit 43 also moves accordingly. Driven by the rotating shaft 41, the scanning angle of the scanning component 3 changes, thereby realizing the scanning of the inner wall area. When the driving unit 43 rotates, the scanning component 3 can perform angle-changing scanning within a relatively stable range.

[0037] See Figure 2In the cleaning structure of this embodiment, the cleaning structure further includes: a drive motor 44, which is disposed on the side of the scanning component 3 away from the first communicating cavity 211; a drive shaft 45 connected to the output shaft of the drive motor 44, and the drive shaft 45 is provided with an external thread; and a drive slider 46, which is used to push the drive unit 43. The drive slider 46 is movably connected to the scanning head 25, and the drive slider 46 is provided with a connecting hole, and the connecting hole is provided with an internal thread that mates with the external thread, so that the drive slider 46 can be moved by rotating the drive shaft 45. The output shaft of the drive motor 44 and the drive slider 46 are relatively movable through a threaded engagement. When the drive motor 44 drives the drive slider 46 to move, the drive slider 46 pushes the drive unit 43 to move, and the drive unit 43 causes the scanning component 3 to move to achieve angular scanning of the cleaning beam 20.

[0038] See Figure 2 In the cleaning structure of this embodiment, the driving part 43 is a rod-shaped structure, which passes through the fixed base 42. One end of the driving part 43 abuts against the scanning component 3, and the other end of the driving part 43 abuts against the driving slider 46. This beam structure allows the scanning component 3 to better distribute the driving force generated by the driving slider 46, preventing damage caused by excessive force on the scanning component 3.

[0039] See Figure 2 In the cleaning structure of this embodiment, the drive slider 46 includes a connecting surface 461 that abuts against the drive part 43. The connecting surface 461 and the rotation axis of the drive shaft 45 have a preset angle, which is an acute angle. The angle between the connecting surface 461 and the rotation axis of the drive shaft 45 is less than 90°. One end of the rod-shaped drive part 43 abuts against the connecting surface 461, and the other end abuts against the scanning component 3, thus forming an approximately Z-shaped structure. This Z-shaped structure can effectively withstand pressure and tension and transfer them to other parts of the structure. In the Z-shaped structure, due to the presence of the oblique crossbeam (i.e., the drive part 43), the force signal can be distributed more evenly throughout the entire structure, making the entire structure more stable. Furthermore, the oblique crossbeam (drive part 43) of the Z-shaped structure can also increase the stiffness and strength of the structure, thereby improving its overall load-bearing capacity and seismic performance.

[0040] See Figure 2In the cleaning structure of this embodiment, the cleaning structure also includes an elastic element 5. The elastic element 5 is located on the side of the drive unit 43 away from the rotating shaft 41. One end of the elastic element 5 is connected to the scanning component 3, and the other end of the elastic element 5 is connected to the fixed base 42. In order to better improve the pressure resistance and shock resistance of the scanning component 3, the elastic element 5 reduces the power transmitted to the scanning component 3 by the drive motor 44.

[0041] See Figure 3 In the cleaning structure of this embodiment, the cleaning structure further includes: a lens component 7 for imaging, which is disposed on the inner wall of the second communicating cavity 212; and an illumination component 8 for emitting light, which is disposed on the inner wall of the second communicating cavity 212 and is disposed opposite to the lens component 7. The illumination component 8 is used for area illumination, and the lens component 7 is used for imaging and detection of the illuminated area.

[0042] See Figure 1 In the cleaning structure of this embodiment, the telescopic component 2 abuts against the first container opening 101 of the container 10, and the telescopic component 2 and the container 10 are rotatably connected relative to each other along a first rotation axis; the telescopic component 2 is rotatably arranged along a second rotation axis; wherein, the second rotation axis is arranged parallel to the extension direction of the cleaning beam 20 in the communicating cavity 21, and the first rotation axis and the second rotation axis are arranged perpendicular to each other. In this embodiment, the first container opening 101 is used to abut against the telescopic component, and the second container opening 102 is used to discharge the gaseous particles and dust generated during cleaning to the exhaust port outside the container 10.

[0043] Specifically, see Figures 4 to 7 The telescopic component 2 enters from the first container opening 101 and drives the scanning component 3 to telescopically move within the container 10.

[0044] See Figure 4 When scanning component 3 moves from A2 to A1, the scanning area is CED, and the cleaning of the CED area is completed;

[0045] See Figure 5 The telescopic component 2 rotates along the second preset axis, moving from A2 to A1, scanning the FGH area, and completing the cleaning of the FGH area;

[0046] See Figure 6 The telescopic component 2 rotates along the first preset axis, and the scanning component 3 moves from B2 to B1, scanning the LMN area to complete the cleaning of the LMN area;

[0047] See Figure 7 The telescopic component 2 rotates along the second preset axis, moving from B2 to B1, scanning the KJI area, and completing the cleaning of the KJI area.

[0048] By extending and retracting the telescopic component 2 and rotating it along the first preset axis and the second preset axis, the cleaning beam is scanned, thereby achieving full-coverage internal scanning and cleaning.

[0049] In some embodiments of the cleaning structure, a galvanometer assembly 9 and a reflector 6 are also provided outside the container 10. When the light source assembly 1 emits a cleaning beam 20 toward the inner wall of the container 10, the cleaning beam 20 cleans the inner wall by means of the oscillation of the galvanometer assembly 9 and the reflector 6, as well as the rotation and extension of the light guide rod 24.
