Description

Technical Field

[0001] The utility model belongs to the technical field of mixing equipment, and particularly relates to a corrosion-resistant external mixer for hydrogen fluoride. Background Art

[0002] Most of the current mixing equipment mixes materials in a shell by rotating a stirring shaft. However, some materials (such as hydrogen fluoride) are corrosive and will corrode the shell and the stirring shaft during the mixing process, thereby reducing the service life of the mixing equipment.

[0003] In order to improve the service life of the mixing equipment, a corrosion-resistant layer is provided on the inner side of the shell and the outer side of the stirring shaft. However, the stirring shaft is generally provided with blades or stirring rods. If corrosion-resistant layers are provided on both the blades or stirring rods, the shape of the corrosion-resistant layer is relatively complex and difficult to process and produce. Therefore, the blades or stirring rods are mostly provided as detachable wholes, and are replaced when corroded. This kind of structure has a high replacement cost, and since the blades or stirring rods are inside the shell, the entire stirring shaft needs to be removed for replacement, and the process is relatively complex.
