Description

Technical Field

[0001] The utility model relates to the technical field of agitator structures for glass-lined reactors, and particularly relates to a wear-resistant agitator for a glass-lined reactor. Background Art

[0002] A glass-lined reactor is a composite material product in which glass containing high silica is lined on the inner surface of a steel container and firmly adhered to the metal surface through high-temperature calcination. Therefore, it is an excellent corrosion-resistant device. An agitator is a device that forces the convection and uniform mixing of liquid and gas media. The type, size, and rotational speed of the agitator all affect the distribution of the stirring power between the overall flow and the turbulent pulsation.

[0003] There are certain drawbacks in the use of the agitator of the existing glass-lined reactor. The agitator in the traditional glass-lined reactor does not have a cleaning structure. Stirring materials will remain on the surfaces of the stirring rod and the stirring blades, which will corrode the surfaces of the stirring rod and the stirring blades. Moreover, the edges of the stirring blades will continuously collide with the stirring materials, with low bearing capacity and insufficient wear resistance of the stirring blades. Summary of the Utility Model
