Description

Technical Field

[0001] This utility model relates to the field of graphite product transportation technology, specifically to a high-temperature gas-cooled stack graphite ball packaging inner tray component. Background Technology

[0002] The high-temperature gas-cooled reactor (HTGR) is an advanced nuclear reactor that uses helium cooling and graphite moderation, with an operating temperature exceeding 950°C. Its core uses TRISO-coated pellet fuel, approximately 0.5 mm in diameter, capable of withstanding temperatures up to 1600°C and possessing inherent safety—the core will not melt down even if the cooling system completely fails. Its modular design allows for a thermal efficiency of up to 50%, far exceeding that of traditional reactors. The graphite sphere fuel elements are one of the core design features of the HTGR, representing a significant innovation in fourth-generation nuclear reactor technology. Due to the unique structure and special processing of the graphite spheres, their stability during transportation must be ensured. Traditional graphite sphere packaging structures are relatively simple, offering only limited support and failing to meet production requirements, resulting in a lower yield rate after the graphite spheres arrive at the site.

[0005] Preferably, the packaging box is a box structure made of wooden boards, and a shock-absorbing pad is provided between the inner surface of the packaging box and the cardboard container. The upper end of the packaging box is provided with a cover plate, and the lower end of the packaging box is provided with a forklift loading slot.

[0006] Preferably, the base plate, the lower limit plate, the support base, the upper limit plate, and the top plate are all foamed plastic sheet structures.

[0008] Preferably, a support groove is provided at the middle position of the upper surface of the support base, and the thickness of the support base is half the thickness of the lower limiting groove.

[0009] Compared with the existing technology, the beneficial effects of this utility model are: replacing the traditional graphite ball packaging structure, redesigning a multi-layer graphite ball packaging structure, protecting against scratches and bumps during transportation with wooden packaging boxes, setting up vacuum bags to avoid the impact of humid environment on graphite balls, improving the support effect of graphite balls, achieving the protection capability required for production, and ensuring the yield rate of graphite ball products after transportation to the site.

An upper limiting plate 8 is provided at the upper end of the lower limiting plate 4. An upper limiting groove 9 is opened on the upper limiting plate 8 at the position corresponding to the lower limiting grooves 5. A top plate 10 is glued to the upper surface of the upper limiting plate 8. The outer surface of the cardboard containers 2 is covered with a vacuum bag 11.

[0017] In use, the lower limit plate 4 and the base plate 3 are glued together as a whole, and the upper limit plate 8 and the top plate 10 are glued together as a whole. The finished graphite ball is placed inside the lower limit groove 5 of the lower limit plate 4. During handling, retrieval grooves 6 are provided on both sides of the lower limit groove 5 to facilitate handling by the staff. A support seat 7 is provided on the base plate 3 inside the lower limit groove 6 to support the lower end of the graphite ball. Then, the top plate 10, carrying the upper limit plate 8, is attached to the lower limit plate 4. At this time, the upper limit groove... The upper end of the graphite ball is limited by plate 9 and protected by plate 10. Then, the bottom plate 3, lower limit plate 4, upper limit plate 8 and top plate 10 are placed inside the cardboard box 2. The cardboard box 2 protects the overall structure. Vacuum bags 11 are placed on the outside of the cardboard box 2 to isolate the graphite ball from the external environment. Multiple cardboard boxes 2 are stacked inside the packaging box 1. The cardboard box 2 can effectively ensure the stacking of multiple layers. The packaging box 1 protects against scratches and bumps during transportation.
