Description

Technical Field

[0001] This invention relates to the field of reduced iron powder processing technology, specifically a special equipment for extracting and separating ultrafine powder from reduced iron powder. Background Technology

[0002] Reduced iron powder, a gray or black powder also known as a "dual absorbent," can absorb moisture and oxygen from the air and has wide applications in industrial production and other fields. Among them, ultrafine powder (such as powder with a particle size of less than 10μm) is experiencing a surge in demand in high-end manufacturing scenarios such as electronic components and advanced catalysts due to its high specific surface area and good activity. However, the separation of ultrafine powder in its production process presents the following challenges: 1. Low separation efficiency: Traditional screening equipment relies on the natural screening of materials. Agglomerated reduced iron powder particles are difficult to disperse. Furthermore, because reduced iron powder easily absorbs moisture and oxygen, ultrafine powder is more likely to clog the screen. The separation speed is slow and the output is low, which cannot match large-scale production.

[0003] 2. Difficult to collect: Ultrafine powder has a small particle size and light weight. After separation, it is easy to disperse or adhere to the inner wall of the equipment due to turbulent airflow and electrostatic adsorption, making it difficult to collect and causing product loss and subsequent cleaning burden.

[0004] 3. Complex operation: Most existing equipment has a split structure, with poor connection between feeding, separation and collection links, requiring frequent manual intervention and adjustment.

[0005] To address the aforementioned issues, there is an urgent need to develop a specialized device that integrates efficient separation, precise collection, convenient operation, and coordinated power transmission to improve the quality and efficiency of ultrafine iron powder separation and meet the stringent requirements of high-end manufacturing for raw materials. This specialized device for ultrafine iron powder extraction and separation is designed accordingly. Summary of the Invention
