Description

Technical Field

[0001] The utility model belongs to the technical field of axial flow stirrers, and in particular relates to an axial flow stirrer with good anti-corrosion effect. Background Art

[0002] HC agitator is a new type of axial flow agitator that can be used for liquid-liquid or liquid-solid two-phase suspension mixing. It is used in many fields, such as construction, pharmaceuticals, chemicals, food, etc.

[0003] In the field of chemical material processing, the stirring and mixing conditions are often harsh and corrosive. In order to ensure the normal use of the agitator, it is generally necessary to coat the outside of the metal agitator with a layer of polytetrafluoroethylene coating to improve the corrosion resistance of the agitator. However, during the use of the agitator, the blades of the agitator will constantly collide with the material. After long-term use, the anti-corrosion coating on the blades will be damaged, resulting in the failure of the anti-corrosion coating. The blades are susceptible to corrosion, which will cause the agitator to be unable to be used normally.

[0004] Therefore, in order to solve the above problems, it is necessary to design an axial flow agitator with good anti-corrosion effect. Utility Model Content
