Description

Technical Field

[0001] The utility model relates to the technical field of dry powder mixers, in particular to a high-efficiency dry powder mixer. Background Art

[0002] With the rise of industries such as food, medicine, chemical industry, powder metallurgy, and high-tech materials, dry powder mixers have become popular as an efficient mixing equipment. Existing dry powder mixers use mechanical force to fully mix and stir powder materials to achieve a uniform mixing effect. Dry powder mixers are usually composed of a container and one or more rotating stirring elements. When the equipment is started, the stirring element begins to rotate and brings the powder material into the container. The design of the stirring element usually includes scrapers, spirals, stirring arms, etc. to ensure that the materials are fully mixed in the container. During the mixing process, the materials will be continuously subjected to shear, extrusion, and impact forces, so that they are intertwined and dispersed with each other, which will cause materials of different particles to contact each other to achieve the purpose of mixing. Traditional dry powder mixers use scrapers and stirring arms to mix materials, and the motion trajectory and direction are the same, the stirring effect is poor, and the mixing efficiency of dry powder is low. For this reason, we propose an efficient dry powder mixer. Utility Model Content
