powder mixing device

Abstract

The invention provides a powder mixing device belonging to the technical field of material mixing equipment. The powder mixing device comprises a rack, an outer barrel, an inner barrel, a liquid spraying device, an outer barrel driving device and an inner barrel driving device, wherein foot margin holes are formed in the bottom of the rack, a supporting seat is arranged at the upper part of the rack, the outer barrel comprises a cylindrical outer barrel body and an outer barrel upper cover, wherein two trunnions are symmetrically arranged at the two sides of the middle part of the outer barrel body, and are mounted on the supporting seat of the rack, so that the outer barrel swings relative to the rack; the inner barrel can be put into the outer barrel and comprises a cylindrical inner barrel body and an inner barrel upper cover, and an inner barrel upper cover locking device is arranged between the inner barrel body and the inner barrel upper cover, so that the inner barrel upper cover can be conveniently opened or locked; and a spline groove is formed in the bottom of the inner barrel body, a liquid spraying hole is also formed in the bottom of the inner barrel body, and the liquid spraying device can be used for atomizing a liquid material and injecting the atomized liquid material into the inner barrel through the liquid spraying hole. The powder mixing device has the advantages that the liquid material and a solid material can be fully mixed and no caking is produced.

Description

technical field [0001] The invention belongs to the field of material mixing equipment, in particular to a powder mixing device. Background technique [0002] Material mixing is a process in which particles with different physical and chemical properties are evenly distributed macroscopically by mechanical or fluid methods. Mixing uniformity is the degree of uniform distribution of components in the mixture, which refers to the closeness between the number of particles of a certain component contained in any unit volume or unit weight of the mixture and the average content, and is an important indicator for examining the quality of material mixing. . [0003] Mixing equipment is a mechanical device that uses mechanical force and gravity to uniformly mix two or more materials. Common mixers include: coulter mixer, ribbon mixer, gravity-free mixer, V-type mixer, double-helix conical mixer, high and low speed liquid mixer, planetary power mixer, etc., widely used in pharmaceu...

AI Technical Summary

Problems solved by technology

[0006] It is often necessary to add a small amount of liquid substances such as lubricating liquid, liquid catalyst, liquid binder and other auxiliary materials during material mixing. If they are directly added to powder materials, agglomerates will form, and the agglomerates are not easy to disperse during mixing, resulting in uneven liquid mixing and Particles are produced, which affect the mixing effect
