High-speed operation, rapid and large-scale extraction and discharge of air and powder; 2. For extracting air or powder containing hard impurities, an air guide device 10 with a wind wheel 103 having a wear-resistant blade structure can be selected. The wind wheel 103 with a wear-resistant blade structure can prevent the wind wheel 103 from being worn by the high-speed impact of hard impurities when extracting air or powder, thereby increasing the service life of the wind wheel 103 and the effective operation time of the integrated centrifugal fan; 3. For extracting corrosive gases or powders, an air guide device 10 with a wind wheel 103 having a corrosion-resistant blade structure can be selected. By automatically replacing the air guide device 10 with a wind wheel 103 of different structures within the air guide cabin 5, the application environment of the integrated centrifugal fan can be expanded. When extracting gas or powder in the same environment, the use state of the integrated centrifugal fan can be quickly switched as needed, thereby increasing the service life of the integrated centrifugal fan and eliminating the need to replace the centrifugal fan and the supporting pipelines as in the traditional method, thereby improving the efficiency of extracting gas or powder from the environment.

[0048] The integrated centrifugal fan centrifugally extracts gas or powder in the following manner: after assembling an air guide device 10 in the air guide cabin 5, turning on the drive motor 73, the drive motor 73 drives the air guide device 10 to rotate through the main drive shaft 74, so that the air guide device 10 generates negative pressure from the connecting pipe 6 through the air guide cabin 5, thereby sucking in gas or powder and discharging it from the air outlet structure of the air guide cabin 5.

[0049] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
