[0002] Inorganic superfine powder, such as calcium carbonate, talc, barium sulfate, magnesium hydroxide, silicon powder, etc., has the characteristics of small particle size, large specific surface area, high surface energy, etc., and is widely used in building materials, rubber and plastic, coatings, adhesives and other fields. When packaging inorganic superfine powder, due to the fine powder particles, there is a lot of air between the particles, if not effectively treated, it will cause the packaged powder to be loose, occupy a large space, and in the process of transportation and storage, it is easy to cause the powder to be layered and caked due to vibration and other factors, affecting the product quality and performance.

[0003] Traditional powder packaging equipment mostly only fills simply, lacks effective exhaust and compacting measures. Some use vibration or tapping to achieve powder compaction, but dust is easily flying around in the process of vibration or tapping, not only polluting the environment, but also possibly harming the health of the operators; at the same time, the effect of vibration or tapping is limited, it is difficult to make the powder reach the ideal compacting degree.

[0004] Therefore, there is an urgent need for a device that can effectively exhaust the air inside the inorganic superfine powder packaging and achieve compacting packaging, while reducing dust pollution. SUMMARY
