Technical Field

[0002] With the rapid development of society, energy and environmental issues are becoming increasingly prominent, the new energy market has been developed on a large scale and widely used, and people's requirements for battery performance in the new energy industry have become higher and higher; in the production process of battery production lines, powder feeding and conveying equipment are used most frequently. In order to improve product quality and production efficiency, gas conveying is often used to convey materials. The negative pressure conveying system is the most common form of gas conveying. Negative pressure conveying is an advanced material handling equipment with the advantages of simple structure, easy operation, and reliable operation. It can convey loose, dry powdered or granular materials horizontally, obliquely and vertically.

[0003] The principle of negative pressure conveying is to form a negative pressure airflow under the action of vacuum, under the action of this airflow, the material in the delivery bin is conveyed to another container through the suction hose or tube. Since the material is always in a vacuum state during the conveying process, even if the pipeline leaks, the material will not leak into the surrounding environment.

[0004] However, in actual production, due to the different specific gravity, water absorption and other characteristics of different materials, during the powder conveying process, the material outlet at the bottom of the buffer silo is prone to blockage, causing the negative pressure fan to be easily overloaded and the material to be easily pumped out.
