Description

Technical Field

[0001] The utility model belongs to the technical field of powder classifiers, and more specifically, relates to a powder classifier with high powder classifying efficiency. Background Art

[0002] A powder classifier is a device used to classify and select materials. It is used in the material classification and powder selection processes in the cement, pharmaceutical, chemical, food and other industries. Among them, the unpowered powder classifier is a common type of powder classifier. It selects powder through physical methods and does not require an external power source. Therefore, it has low energy consumption and low production costs. Existing unpowered powder classifiers are generally composed of an equipment body, a feed port, a discharge port, a dust outlet, an air inlet and an internal classifying wheel.

[0003] Existing application number: CN202323112490.8, the utility model discloses an efficient powder classifier, comprising a classifier barrel and a feeding bin fixedly connected to the top of the classifier barrel for feeding materials, the top of the feeding bin is provided with a feeding structure for uniform feeding, the feeding structure comprises multiple groups of feeding pipes, the top of the feeding pipe is provided with a material guide member for guiding the flow direction of the material, a dispersion structure for screening the material is provided inside the classifier barrel, and one side of the classifier barrel is provided with an air inlet structure for blowing away the material. The utility model arranges a feeding structure at the feeding bin of the V-type powder classifier, increases the single feeding pipe to multiple feeding pipes, and adds a material guide trough between the feeding pipe and the hopper to make the material evenly distributed into the multiple feeding pipes, so that the material enters the V-type powder classifier through the feeding bin and is redirected by the scattering plate, so as to achieve uniform material film thickness inside the V-type powder classifier and avoid inability to fully screen the material.
