Description

Technical Field

[0001] This utility model relates to the field of air classifier technology, specifically an air classifier for fuel rod production. Background Technology

[0002] Air separation utilizes the difference in suspension velocity between materials and impurities to remove impurities using wind power. The purpose of air separation is to remove light impurities and dust, while also removing some heavier impurities such as stones and clods of soil. When applied to waste sorting, it can remove heavier metal substances from waste, facilitating the classification and treatment of waste.

[0003] After completing air separation, the multi-stage air separator discharges the airflow through the outlet. Because lighter waste is carried up by the airflow, it tends to float. Furthermore, the waste transport mechanism is often a simple conveyor belt, resulting in waste piling up on the conveyor belt during transport. This not only affects the screening effect of the air separation but also impacts the processing environment. Therefore, we propose an air separator for fuel rod production. Utility Model Content

[0004] The existing waste transportation mechanisms are mostly ordinary conveyor belts, which cause waste to be piled up on the conveyor belt during transportation, affecting the screening effect of air separation and also impacting the processing environment. This utility model provides an air separator for fuel rod production, which has the advantages of improving air separation efficiency, ensuring the separate transportation of waste, and ensuring screening effect, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A wind classifier for fuel rod production includes a second worktable. Multiple first and third rotating shafts are rotatably connected to the second worktable at intervals. A first rotating roller is connected to the first rotating shaft, and multiple cams are connected to the third rotating shaft. A second conveyor belt is connected to the outside of the cams and the first rotating roller. The ends of the first and third rotating shafts are connected to a drive mechanism. A processing cover is connected to the top of the second worktable. Multiple air inlets are provided on one side of the processing cover. Each air inlet is connected to a blower through an air duct. An air outlet with the same number as the air inlets is provided on the other side of the processing cover. A downwardly curved discharge pipe is connected to the outside of the air outlet. A transport mechanism is connected to one side of the second worktable, and the transport mechanism is located directly below the discharge pipe.

Detailed Implementation

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. 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.

[0022] Reference Figures 1 to 4 This utility model provides a technical solution: an air separator for fuel rod production, comprising a second worktable 10, on which a plurality of first rotating shafts 11 and third rotating shafts 25 are rotatably connected. First rotating rollers 20 are connected to the first rotating shafts 11, and a plurality of cams 21 are connected to the third rotating shafts 25. A second conveyor belt 14 is connected to the outside of the cams 21 and the first rotating rollers 20. Figure 1 , 4 As shown, pulleys 12 are fastened to one end of multiple first rotating shafts 11 and third rotating shafts 25. Adjacent pulleys 12 are connected by belts. A first motor 15 is connected to one end of the rotating shaft. Driven by the first motor 15, multiple first rotating shafts 11 and third rotating shafts 25 can be driven to rotate synchronously. Under the rotation of the cam 21, the second conveyor belt 14 can be driven to vibrate up and down, thereby vibrating the waste on its top, which is beneficial to improving the efficiency of air separation.

[0023] like Figure 2 , 4As shown, a processing cover 5 is connected to the top of the second workbench 10, and one side of the processing cover 5 is open. A feed inlet 2 is opened at the top of the end of the processing cover 5 away from the opening. A feed hopper 1 is connected to the top of the feed inlet 2. A downwardly extending inclined plate 26 is connected to the lower end of the inner wall of the processing cover 5. The inclined plate 26 is located directly below the feed inlet 2, and the end of the inclined plate 26 extends to the top of the second conveyor belt 14. A downwardly extending guide plate 13 is connected to the end of the second conveyor belt 14 away from the feed hopper 1. Waste falls from the feed hopper 1 and falls to the top of the second conveyor belt 14 for transportation. Under the guidance of the inclined plate 26, it can be ensured that the waste falls fully to the top of the second conveyor belt 14 for the next step of air separation processing. After the air separation processing is completed, under the guidance of the guide plate 13, it is convenient to transport the waste with larger mass after air separation.

[0024] like Figure 2 , 3 As shown, multiple air inlets 27 are provided on one side of the processing hood 5. Each air inlet 27 is connected to a fan 4 via an air duct 3. A connecting cover 9 is connected to the outside of the air inlet 27, and the connecting cover 9 is connected to the air duct 3. A dustproof net 19 is connected to the inside of the air inlet 27. During installation, the connecting cover 9 and the dustproof net 19 are connected to the processing hood 5 with bolts. On the other side of the processing hood 5, there are air outlets 24 in the same number as the air inlets 27. A downwardly curved discharge pipe 18 is connected to the outside of the air outlet 24. Lighter waste materials after being air-separated by the fan 4 are discharged from the discharge pipe 18. The multiple fans 4 can perform progressive air separation of the waste materials, thereby progressively separating waste materials of different weights. A protective curtain 16 is rotatably connected to the open side of the processing hood 5 to prevent lighter waste materials from flying out of the opening of the processing hood 5, thus achieving effective air separation of waste materials.

[0025] In summary, when using this air separator for fuel rod production, if... Figure 2 , 4As shown, a transport mechanism is connected to one side of the second workbench 10. The transport mechanism is located directly below the discharge pipe 18. In actual use, multiple transport mechanisms are set, and each transport mechanism corresponds to a multiple discharge pipe 18, so that the waste separated by air separation from each discharge pipe 18 can be transported separately, ensuring the quality of air separation. The transport mechanism includes a first workbench 8 connected to one side of the second workbench 10. Multiple second rotating rollers 23 are connected to the first workbench 8 through a second rotating shaft 22. A first conveyor belt 7 is connected to the multiple second rotating rollers 23. A second motor 17 is coaxially connected to the second rotating shaft 22 at one end. Protective side plates 6 are symmetrically connected to the top of the first workbench 8. The discharge pipe 18 is located between two protective side plates 6 to prevent the waste from sliding off the side wall of the first workbench 8 after falling, which facilitates the effective transport of waste after air separation. This utility model is not only simple in structure, but also effectively improves the air separation effect.
