Problems solved by technology

[0002] The existing fan will generate a lot of heat when it is in use, and the casing is a relatively sealed space. If the inside of the casing cannot be cooled in time, it will easily cause the fan to malfunction during use. The traditional fan The shells are made of iron materials. With the continuous accumulation of heat, it is easy to make the fan shell burst, causing unnecessary safety hazards.

Abstract

The invention provides a casing of an anti-explosion fan. The casing comprises a casing body. The outer wall of the casing body is coated with an anti-explosion layer, an impeller is arranged in the casing body and connected through a rotating shaft, the lower end of the casing body is fixedly connected with a base, and a fastening screw is arranged on the outer portion of the casing body. The casing is compact in structure and high in safety performance, and by coating the machine casing with a layer of anti-explosion material, the problem of burst of the fan casing body can be solved effectively.

Description

technical field [0001] The invention relates to an explosion-proof fan, in particular to a shell of an explosion-proof fan. Background technique [0002] The existing fans will generate a lot of heat when they are in use, and the casing is a relatively sealed space. If the inside of the casing cannot be cooled in time, it will easily cause the fan to malfunction during use. The traditional fan The shells are made of iron materials. With the continuous accumulation of heat, it is easy to make the fan shell burst, causing unnecessary safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an explosion-proof blower casing with compact structure and high safety performance, which can effectively solve the problems in the background technology. [0004] In order to solve the problems of the technologies described above, the present invention provides the following technical s...
