[0032] When in use, the installation shell 2 can be provided to protect the blade 3 to a certain extent. When working, debris directly collides with the blade 3, which prevents the blade 3 from being damaged and increases the service life.

[0033] In some technical solutions, such as Figure 4 As shown, the exteriors of the multiple groups of blades 3 are all sprayed with a rust-proof and wear-resistant layer.

[0034] During use, by spraying an anti-rust and wear-resistant layer on the outside of the blade 3, the impeller can reduce the wear of the blade 3 by large particles inside the smoke in a usage scenario with heavy smoke, thereby increasing the service life.

[0035] In some technical solutions, such as Figure 1 As shown, a plurality of groups of limit blocks 103 are installed below the carrying shell 1 , and the plurality of groups of limit blocks 103 are evenly arranged on both sides of the plurality of groups of fixing strips 401 .

This setting enables the impeller to replace the angle according to different usage scenarios and performance requirements, so as to change the performance and usage of the impeller, and effectively improves the practicality. By setting the mounting shell 2, the blade 3 can be protected to a certain extent. When working, there are debris that directly collide with the blade 3 to prevent damage to the blade 3 and increase the service life. By spraying an anti-rust and wear-resistant layer on the outside of the blade 3, the impeller can be used in a large smoke and dust environment. In the scenario, the wear of large particles inside the smoke and dust on the blade 3 is reduced, and the service life is improved. By setting the limit block 103, the rotation of the fixing bar 401 can be effectively limited to prevent the blade 3 from being stuck due to excessive rotation angle. By setting the rotating groove 102, the stability of the rotating plate 4 during rotation can be effectively improved, and the setting of the knob 402 can be improved.
