Description

Technical Field

[0001] The invention belongs to the field of metal processing, and in particular relates to a metal powder purification treatment device. Background Art

[0002] With the development of industrial technology, modern metal processing technology has become more and more perfect. After long-term storage, the surface of metal powder particles will be corroded and rusted, which will affect the processing and use of metal powder. In the past, acid was used to process metal powder. During the process of acid dissolving rust, the density of metal powder is greater than that of acid, and the metal powder will be deposited at the bottom of the solution. This will easily lead to uneven contact between the metal powder particles and the solution. The metal powder at the top will be in contact with the acid for a long time, and the acid will also consume the metal powder that has not rusted, resulting in a large amount of loss of metal powder material.

At the same time, the nut block will move back and forth on the threaded rod, and the forked rod on the side wall of the threaded rod will contact the torsion plate. The rotating drum, torsion rod and torsion plate will twist back and forth thirty degrees together, and then the acid liquid and the metal powder will be fully mixed inside the rotating drum, achieving the effect of efficiently mixing the acid liquid and the metal powder, and increasing the uniformity and efficiency of de-corrosion of the metal powder particles, thereby solving the problems mentioned in the background technology.
