Description

Technical Field

[0001] This application relates to the field of centrifugal fans, and particularly to a centrifugal fan with high temperature resistance and wear resistance. Background Art

[0002] A centrifugal fan is a ventilation machine that works based on the principle of centrifugal force. It generates air flow through the rotation of the impeller, sucking in gas axially and discharging it radially. Centrifugal fans are widely used in fields such as ventilation, dust removal, and material transportation in industrial production, and are favored for their high efficiency, high pressure, and low noise. For applications that need to work in high-temperature and abrasive environments, centrifugal fans with high temperature resistance and wear resistance are used. The design of such fans needs to consider the special working environment, so there will be differences in material selection, structural design, etc. Such fans are commonly used in industries such as high-temperature flue gas treatment, industrial furnaces, chemical plants, and metallurgy.

[0003] Some existing centrifugal fans are limited by the installation location, and the motor and the impeller need to be directly connected by a coupling. When the centrifugal fan transports some high-temperature flue gas, it is easy to cause the motor to overheat and affect the use, which is rather inconvenient. Summary of the Utility Model
