Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically a screening equipment for the production of graphitized anode materials. Background Technology

[0002] Screening equipment plays a crucial role in the production of graphitized anode materials. It ensures uniform particle size distribution, removes impurities, and improves overall material quality. Most of this screening equipment is the ultrasonic vibrating screen, a highly efficient screening device particularly suitable for screening fine powders such as graphite. It uses high-frequency vibration waves generated by an ultrasonic generator to cause micro-vibrations in the material on the screen, effectively solving the screening challenges of sticky, agglomerated, statically charged, and strongly adsorbent materials. Ultrasonic vibrating screens are characterized by high screening efficiency, high screening accuracy, and resistance to screen clogging.

[0003] When existing ultrasonic vibrating screens are in use, if a large amount of external material enters the screen, the material tends to accumulate in one area of ​​the screen. When the material accumulates in one area, the effective screening area of ​​the screen surface is reduced, resulting in a significant decrease in screening efficiency. The accumulated material will also hinder other materials from passing through the screen, making the overall screening process slower. Furthermore, the accumulated material will exert additional pressure on the screen, which may cause the screen to deform, break, or loosen. This not only affects the screening effect but may also increase the frequency and cost of replacing the screen. Utility Model Content

An ultrasonic screen 8 is installed inside each screen frame 6, and ultrasonic transducers 9, which cooperate with the ultrasonic screen 8 and an external ultrasonic generator, are mounted on each screen frame 6. A dispersion mechanism, including a housing 13 and a distribution component 19, is mounted on the top cover 10 to disperse the material entering through the feed inlet 11. The dispersion mechanism includes a housing 13 and a distribution component 19. The base frame 1 serves as the supporting structure for the entire device. The vibration springs 2 provide elastic support, enabling the mounting frame 3 and its screening system to generate effective vibration, thereby promoting… In the screening process, mounting frame 3 is used to install and support various components of the screening system, such as screen frame 6 and vibration mechanism 4. Screen frame 6 is the core component of the screening process, and it is equipped with ultrasonic screen 8. Ultrasonic vibration prevents screen clogging and improves screening efficiency. Ultrasonic screen 8, combined with ultrasonic technology, can more effectively separate materials and reduce screen clogging. Ultrasonic transducer 9 works with ultrasonic screen 8 to convert the energy of the external ultrasonic generator into mechanical vibration, which acts on the material on the screen. Vibration mechanism 4 provides power to the screening system, causing it to vibrate regularly, which helps the material pass through the screen. The material is evenly distributed and rapidly screened. The discharge frame 12, located below the screen frame 6, collects the screened material. Discharge port 5 and discharge port 7 are respectively located on the discharge frame 12 and screen frame 6 to discharge the screened material from the equipment.

Through the installation of the housing 13 and the distribution component 19, when material enters the pipe 14 from the inlet 11, the motor 23 starts, driving the rod 21 to rotate. The rotation of the rod 21 drives the gear 22 to rotate, thus discharging the material through… The meshing relationship drives the gear 20 and the rotating rod 18 to rotate. The rotation of the rotating rod 18 drives the material distribution component 19 to rotate, dispersing the falling material and making it fall evenly on the screen. This allows the material to make fuller contact with the screen, increasing the effective screening area and reducing the accumulation and clogging of material on the screen. This makes the screening process smoother and avoids uneven screening and particle size deviation caused by material accumulation. Moreover, after the material is evenly dispersed, the impact force on the screen is reduced, which slows down the wear rate of the screen and reduces the risk of equipment overload and failure caused by material accumulation, thereby improving screening efficiency and quality.

[0020] Please see Figure 3 and Figure 4The housing 13 is mounted on the top cover 10 and located below the feed inlet 11. Inside the housing 13 is a pipe 14 that mates with the feed inlet 11. Inside the pipe 14, a shell 16 is mounted via multiple sets of connecting rods 15. A rotating rod 18 is rotatably mounted on the shell 16. A material distribution component 19 is fixedly mounted at the bottom end of the rotating rod 18 and is located outside the housing 13. A gear 20 is fixedly mounted on the rotating rod 18 and is located inside the pipe 14. Inside the pipe 14, a rod 21 is rotatably mounted. A gear 22 is fixedly mounted at one end of the rod 21 and is located inside the pipe 14. The motor 23 is fixedly mounted on the outside of the pipe 14, and the output end of the motor 23 is fixedly connected to one end of the rod 21. The housing 13 serves to protect and support the internal components. The pipe 14 is located inside the housing 13 and is the channel for materials to enter the dispersing mechanism, ensuring that the materials can enter the dispersing mechanism smoothly. The outer shell 16 is fixed inside the pipe 14 by the connecting rod 15, providing stable support for the rotating rod 18. A material distribution component 19 is fixedly mounted at the bottom of the rotating rod 18 to disperse the incoming materials. Gear 20 is fixedly mounted on the rotating rod 18, located inside the pipe 14, and meshes with gear 22. To achieve power transmission, the material distribution component 19 is located outside the housing 13 and rotates with the rotating rod 18, evenly dispersing the material onto the screen. The material distribution component 19 can be replaced according to the characteristics of the material and screening requirements to ensure optimal dispersion. Gear 1 20 is fixed to the rotating rod 18, and gear 22 is fixed to the rod body 21. The two mesh to achieve power transmission. When the motor 23 drives the rod body 21 to rotate, gear 22 drives gear 1 20 to rotate, which in turn drives the rotating rod 18 and the material distribution component 19 to rotate. When the material enters the pipe 14 from the feed inlet 11, the motor 23 starts, driving the rod body 21 to rotate. The rotation of the rod body 21 drives the gears. The rotation of component 22 drives gear 20 and rotating rod 18 to rotate through meshing. The rotation of rotating rod 18 drives the material distribution component 19 to rotate, dispersing the falling material and ensuring it falls evenly onto the screen. This allows the material to make fuller contact with the screen, increasing the effective screening area and reducing material accumulation and clogging on the screen. This makes the screening process smoother and avoids uneven screening and particle size deviation caused by material accumulation. Furthermore, the uniform dispersion of the material reduces the impact force on the screen, lowering the wear rate of the screen and reducing the risk of equipment overload and failure due to material accumulation, thus improving screening efficiency and quality.

[0021] Please see Figure 3 and Figure 4 A conical block 17 is fixedly installed on the top of the outer shell 16. The installation of the conical block 17 not only prevents the material from falling to the top of the outer shell 16 and being unable to fall down, but also causes the material to be subjected to a certain impact force when it hits the conical block 17, thereby further dispersing it.

[0022] Working principle: The base frame 1 serves as the supporting structure for the entire equipment. The vibration spring 2 provides elastic support, enabling the mounting frame 3 and its screening system to generate effective vibration, thereby promoting the screening process. The mounting frame 3 is used to install and support various components of the screening system, such as the screen frame 6 and the vibration mechanism 4. The screen frame 6 is the core component of the screening process, containing an ultrasonic screen 8. Ultrasonic vibration prevents screen clogging and improves screening efficiency. The ultrasonic screen 8, combined with ultrasonic technology, can more effectively separate materials and reduce screen clogging. The ultrasonic transducer 9 works with the ultrasonic screen 8 to convert the energy of the external ultrasonic generator into mechanical vibration, which then acts on the material on the screen. The vibration mechanism 4 provides power to the screening system, causing it to vibrate regularly. The vibration helps the material to be evenly distributed and quickly screened on the screen. The discharge frame 12 is located below the screen frame 6 and is used to collect the screened material. The discharge port 1 5 and discharge port 2 7 are respectively set on the discharge frame 12 and the screen frame 6 to discharge the screened material out of the equipment. The top cover 10 is used to close the top of the screening system to prevent the material from splashing during the screening process. The feed port 11 is located on the top cover 10 and is the entrance for the material to enter the screening system. Through the installation of the housing 13 and the material distribution component 19, when the material enters the pipe 14 from the feed port 11, the motor 23 starts and drives the rod 21 to rotate. The rotation of the rod 21 drives the gear 22 to rotate, which in turn drives the gear 20 and the rotating rod 18 to rotate through the meshing relationship. The rotation of the rotating rod 18 drives the material distribution component 19. The rotating mechanism disperses the falling material, ensuring it falls evenly onto the screen. This allows for more thorough contact between the material and the screen, increasing the effective screening area and reducing material accumulation and clogging. This smoother screening process avoids uneven screening and particle size deviations caused by material buildup. Furthermore, the uniform dispersion reduces the impact on the screen, decreasing wear and tear and mitigating the risk of equipment overload and malfunction due to material accumulation. This improves screening efficiency and quality. The housing 13 protects and supports the internal components. The pipe 14, located inside the housing 13, serves as the channel for material entry into the dispersion mechanism, ensuring smooth material flow. The outer shell 16 is fixed within the pipe 14 via a connecting rod 15. The rotating rod 18 is stably supported by a distribution component 19 fixedly installed at its bottom. This component disperses the incoming material. A gear 20 is fixedly installed on the rotating rod 18, located inside the pipe 14, and meshes with a second gear 22 to transmit power. The distribution component 19 is located outside the housing 13 and rotates with the rotating rod 18, evenly dispersing the material onto the screen. The distribution component 19 can be replaced according to the material characteristics and screening requirements to ensure optimal dispersion. Gear 20 is fixed to the rotating rod 18, and gear 22 is fixed to the rod body 21; their meshing transmits power. When the motor 23 drives the rod body 21 to rotate, gear 22 drives gear 20 to rotate, which in turn drives the rotating rod 18 and the distribution component 19 to rotate.When material enters pipe 14 through inlet 11, motor 23 starts, driving rod 21 to rotate. The rotation of rod 21 drives gear 22 to rotate, which in turn drives gear 20 and rotating rod 18 to rotate through meshing. The rotation of rotating rod 18 drives material distribution component 19 to rotate, dispersing the falling material and ensuring it falls evenly onto the screen. This allows for more thorough contact between the material and the screen, increasing the effective screening area and reducing material accumulation and clogging on the screen. This makes the screening process smoother, avoiding uneven screening and particle size deviation caused by material accumulation. Furthermore, the uniform dispersion of the material reduces the impact force on the screen, lowering the screen wear rate and reducing the risk of equipment overload and malfunction due to material accumulation, thus improving screening efficiency and quality. The installation of conical block 17 not only prevents material from falling to the top of outer casing 16 but also provides a certain impact force when the material hits the conical block 17, further dispersing it.
