Detailed description of the preferred embodiments

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: an anti-corrosion fan comprises an impeller wheel disc 1, an inner reinforcing ring 2, an outer reinforcing ring 3, blades 4, a sound absorbing sleeve 5, a mounting bolt 6, a reinforcing balance rib 7, a shaft disc 8, a shaft disc reinforcing rib 9, an impeller rear disc 10, reinforcing pieces 11 and a shell 12, wherein the impeller wheel disc 1 and the impeller rear disc 10 are both positioned in the shell 12, the inner reinforcing ring 2 and the outer reinforcing ring 3 are respectively sleeved on one side of the impeller wheel disc 1, the blades 4 and the reinforcing pieces 11 are respectively fixed between the impeller wheel disc 1 and the impeller rear disc 10, the sound absorbing sleeve 5 is installed on the outer surface of each blade 4 through the mounting bolt 6, the outer surface of the impeller rear disc 10 is fixed with the reinforcing balance ribs 7, the shaft disc 8 is installed at the middle position of the outer surface of the impeller rear disc 10, the shaft disc reinforcing rib 9 is installed on the outer surface of the shaft disc 8 to improve the stability of the shaft disc 8, so that the fan can be stably operated.
