[0002] Nuclear-grade graphite, as a high-performance material, has wide applications in the nuclear industry. Its preparation process involves multiple complex steps, among which sieving devices play a crucial role. Sieving effectively removes impurities and substandard particles from the raw materials, ensuring the quality and performance of the final product. Therefore, it is necessary to design a sieving device for the preparation of nuclear-grade graphite materials.
[0003] To address this, patent CN214975482U discloses a sieving device for preparing graphite anode materials. The device includes a housing, with a sieving device mounted on the inner wall of the housing at an inclined sieving outlet. The sieving device comprises a first mounting member, a second mounting member, and a screen fixed at both ends by the first and second mounting members, respectively mounted on the inner walls of corresponding sides of the housing. This device can directly discharge powder that has not passed through the screen from the sieving outlet for further pulverization, thus avoiding clogging of the screen holes. Furthermore, the screen of the sieving device can be disassembled and removed from the sieving outlet for cleaning or replacement, improving sieving efficiency.
[0004] Although the screening device mentioned above for preparing graphite anode materials is easy to disassemble and clean during use, it can easily cause dust to fly up during material screening, affecting the screening environment in the workshop. Therefore, it is necessary to design a screening device for the preparation of nuclear-grade graphite materials. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0028] Please see Figures 1-6 The present invention provides a sieving device for the preparation of nuclear-grade graphite materials, including a sieving component 1.
[0029] Reference Figures 1-3 , Figure 5 and Figure 6 The screening assembly 1 includes a lower housing 11, a screening chamber 12, a reserved groove 13, a cover 14, a feed hopper 15, and a door panel 16. The screening chamber 12 is located inside the lower housing 11. A reserved groove 13 is located inside the lower housing 11 on one side of the screening chamber 12. The cover 14 is hinged to the top of the lower housing 11, and the feed hopper 15 is fixed inside the cover 14. A door panel 16 is hinged to one side of the bottom of the lower housing 11. A dust collection structure 2 is fixed to the outer wall of the lower housing 11 outside the reserved groove 13. The assembly includes a collection box 21, a guide plate 22, a filter cloth 23, and a suction fan 24. The suction fan 24 is fixed to the outer wall of the lower box 11 outside the reserved groove 13. The guide plate 22 is fixed on the outer wall of the suction fan 24 away from the lower box 11. The filter cloth 23 is fixed on the inner wall of the guide plate 22. The collection box 21 is located below the guide plate 22 on one side of the screening assembly 1. The collection box 21 and the guide plate 22 are connected to each other through a pipe. The central axis of the suction fan 24 is collinear with the central axis of the reserved groove 13.
[0030] When the external power supply is connected and the suction fan 24 is started, the suction fan 24 will start to draw air out of the screening chamber 12 and discharge it to the outside of the lower box 11. When the air inside the screening chamber 12 is discharged into the outside air, it will be filtered by the filter gauze 23. The filter gauze 23 can isolate fine dust in the air and prevent dust-laden air from being discharged into the air and polluting the environment.
[0031] Reference Figures 2-6 The top of the screening chamber 12 is provided with a screening structure 3, which includes a handle 31, a first screening box 32, a first electric push rod 33, a second screening box 34, a first screening hole 35, a second screening hole 36, and a second electric push rod 37. The second screening box 34 is located at the top of the screening chamber 12. The bottom of the second screening box 34 is evenly provided with second screening holes 36. The top of the second screening box 34 is connected to the first screening box 32. The bottom of the first screening box 32 is evenly provided with first screening holes 35. The top of the first screening box 32 is fixed with handles 31 on both sides. The bottom of the second screening box 34 is provided with a first electric push rod 33 on one side and a second electric push rod 37 on the other side. The ends of the first electric push rod 33 and the second electric push rod 37 away from the second screening box 34 are both fixedly connected to the inner wall of the lower box 11. The inner diameter of the first screening hole 35 is larger than the inner diameter of the second screening hole 36.
[0032] When an external power source is connected, the first electric push rod 33 and the second electric push rod 37 are activated, causing the first electric push rod 33 and the second electric push rod 37 to extend and retract alternately. This pushes the second screening box 34 and the handle 31 to move back and forth, making reciprocating motions. This can screen the materials inside the handle 31 and the second screening box 34. After screening, the cover 14 can be opened to facilitate the removal, cleaning, and discharge of the first screening box 32 and the second screening box 34 from the screening chamber 12.
[0033] Reference Figures 1-3 and Figure 5 The bottom of the screening structure 3 is provided with guide structures 5 on both sides. The guide structure 5 includes balls 51, support plates 52 and sliding grooves 53. The support plates 52 are fixed on the inner walls of the lower boxes 11 on both sides below the second screening box 34. The top of the support plates 52 is provided with sliding grooves 53. The balls 51 are evenly distributed on both sides of the bottom of the second screening box 34. The balls 51 are symmetrically distributed on both sides of the second screening box 34. The balls 51 are evenly distributed inside the second screening box 34. The support plates 52 are symmetrically distributed on both sides of the second screening box 34. The bottom of the screening cavity 12 below the guide structure 5 is provided with a receiving box 4.
[0034] When the second screening box 34 moves, it can be slidably connected to the support plate 52 via the ball bearings 51, which can reduce the friction between the bottom of the second screening box 34 and the support plate 52, making the second screening box 34 move more smoothly, reducing jamming, and ensuring the screening effect.
[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
