Description

Technical Field

[0002] Chinese patent document CN217797384U discloses a dynamic and efficient powder classifier for raw materials. By setting a powder classifier body, when personnel select cement raw materials, they are connected to the powder classifier body through a feed pipe, which facilitates the injection of materials to be selected into the powder classifier body through the feed pipe. After injection, the second fan is turned on by an external power supply to select powder. When selecting powder, it is fixed on the telescopic tube through a fixing piece, so that when the personnel turn on the external power supply, the power device drives the first rotating shaft to rotate, and the telescopic tube is driven to rotate through the fixing piece. When rotating, a first fan is fixed through the inner wall of the air intake pipe, so that the personnel turn on the first fan to inhale air into the telescopic tube through the air intake pipe, and the air intake can be adjusted The angle of air intake for powder selection allows the air intake position to be quickly adjusted during powder selection to prevent the material from condensing after falling. By setting the base, when personnel are selecting the material, the material rises and is limited and diverted through the limit block. The diverted material is embedded in a tank body fixed on the connecting pipe, so that the selected material enters the tank body through the connecting pipe, and then reaches the conveyor belt through the discharge pipe. After arriving, the conveyor belt is sleeved on the second rotating shaft, so that the personnel can drive the conveyor belt to rotate when the external power supply turns on the power device, and the material is received during rotation. When receiving, the material can be discharged quickly and the material can be loaded for production and processing, which makes it more practical and more convenient for later operations.
