[0002] Powder is an indispensable product in industrial manufacturing. Some are manufacturing raw materials, some are fuels like coal powder, and some are even agricultural products. No matter what kind of raw materials, they need to be sent to the required place by conveying devices, and there is not only one kind of powder, and some even have multiple powders sent to the required location at the same time. For example, the raw materials in glass production are all crushed into granular raw materials. Coal powder is more needed in steel and fertilizer production. In the process of powder transmission, it is often necessary to set up a silo that can temporarily stop the flow or divert. Traditional silos generally store or flow one kind of powder in a granary, and the size of the powder particles is basically the same. However, in actual production, due to different users, the required processes are also different. Sometimes it is difficult to meet the quality requirements due to different powder particle sizes. Different users have different requirements, and sometimes powders of different properties are used. Faced with this situation, it is necessary to constantly switch in the production line for different products and different outputs. In some production processes, even according to process requirements, the same powder will be used differently and switched according to its quality and particle size. In some cases, the amount of powder used during use will change from the original design, or even decrease. This will lead to the actual situation of overutilizing the material silo and a big horse pulling a small cart. How to solve these practical problems is a prominent issue facing the factory and a topic that needs to be solved urgently. Summary of the invention
