Square-tapered rotary mixer

Abstract

The invention relates to a square-tapered rotary mixer. The mixer comprises a mixer main body composed of an upper cube and a lower truncated pyramid, and comprises a rotating shaft for providing the mixer rotation power; the mixer also comprises a baffle internal component fixed in the internal cavity of the cube; the baffle internal component comprises a supporting shaft and at least two baffles fixed on the supporting shaft; the supporting shaft is parallel to the rotating shaft of the mixer; gaps exist between the baffles and the axial side wall of the mixer rotating shaft. The corresponding internal component is designed based on the square-tapered mixer, the axial convective mixing of particles is effectively promoted, and thus the particle mixer having the advantages of simple structure operation, low energy consumption and cost and better mixing effect is provided.

Description

technical field [0001] The invention relates to a mixer, in particular to a square-cone rotary mixer. Background technique [0002] In the process of industrial production, it is often necessary to mix two or more materials of different components together according to a certain ratio, and then process them into the final product through a certain process. The uniform distribution of different component particles has a direct impact on the final product. This homogenization operation of particles with different components is called mixing treatment. [0003] The mixing of particles is a very important unit operation in many industrial productions, especially in the production processes of food, medicine, metallurgy, plastics, and fine chemicals. For example, in chemical production, uniform powder mixing creates good conditions for the reaction; in the production of pharmaceutical solid preparations, the uniform level of mixing a very small amount of medicinal ingredients an...

Problems solved by technology

However, square cone mixer is a kind of rotary mixer, the axial mixing is still dominated by diffusion mixing, and the weak axial mixing still exists. Therefore, the product quality is often not high in production, and the mixing The time is longer, the energy consumption will also increase, it is difficult to meet the needs of industrial mixing

[0005] Jiang Maoqiang, Zhao Yongzhi and others disclosed a double-conical mixer with baffles in "Research on Particle Mixing and Increased Mixing Mechanism in Double-conical Mixer", although the double-conical mixer has improved by adding baffles. The degree of mixing, however, the way it is set up does not give full play to the radial and axial mixing effects, and the mixing effect of the mixture is still unsatisfactory
