[0002] As the core component of gas transmission systems such as ventilation and dust removal, centrifugal fans have been widely used in industries such as machinery, electricity, and chemical industry. A centrifugal fan mainly consists of an impeller, a casing, a coupling, and a shaft. The impeller is the main work component that generates wind pressure and transmits energy. In order to improve the use efficiency of centrifugal fans, an impeller structure of a centrifugal fan is required. However, the existing impeller structures of centrifugal fans still have the following deficiencies:

[0003] For example, the utility model with the application number 202222211518.2 discloses an impeller of a centrifugal fan. This utility model adopts a local pressing structure, which increases the strength of the impeller disc. At the same time, it can also reduce the material thickness of the impeller disc, reduce the overall weight of the impeller, reduce the load on the main shaft and bearings, and improve the stability of the fan operation. The addition of auxiliary blades helps to reduce the leakage at the shaft seal while increasing the strength. However, for comparative documents similar to the above application, when using the existing impeller structures of centrifugal fans, since most impeller structures of centrifugal fans are fixedly welded to the mounting plate, when one blade is damaged, the entire impeller needs to be replaced, thus increasing the use cost and causing problems such as a decline in the use efficiency and a reduction in the use efficiency of the impeller structure of the centrifugal fan.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an impeller structure of a centrifugal fan that is convenient for installation is proposed. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: An impeller structure of a centrifugal fan that is convenient for installation, including an impeller frame and a ventilation component. An installation frame is arranged at the rear end inside the impeller frame. A ventilation component is arranged in the middle inside the impeller frame, and the ventilation component includes a servo motor, a mounting plate, a mounting through groove, a mounting block, a blade body, a threaded through hole, and a mounting bolt. The front end of the servo motor is connected to the mounting plate, and a mounting through groove is opened inside the mounting plate.

At the same time, a threaded through hole is opened in the middle inside the mounting block, and a mounting bolt is connected inside the threaded through hole. A protection component is arranged at the front end inside the impeller frame.

[0007] Further, the mounting disc is connected to the servo motor, and the mounting disc is rotationally connected to the impeller frame through the servo motor.

[0008] Further, the internal dimension of the mounting through groove matches the external dimension of the mounting block, and the mounting block is connected to the mounting disc through the mounting through groove.

[0009] Further, the number of the blade bodies is set to eight, and the eight blade bodies are equidistantly distributed outside the mounting disc.

[0010] Further, the internal dimension of the threaded through hole matches the external dimension of the mounting bolt, and the mounting bolt is embedded in the mounting block through the threaded through hole.

[0011] Further, the protection component includes a mounting chute, a fixed magnetic block, a limiting magnetic block, a protection frame and a wedge-shaped net. A fixed magnetic block is additionally arranged at the front end inside the mounting chute, a limiting magnetic block is connected inside the mounting chute, a protection frame is arranged outside the limiting magnetic block, and a wedge-shaped net is arranged inside the protection frame.

[0016] 2. Through the arrangement of the protection component, when the centrifugal fan impeller structure convenient for installation is in use, the protection frame can be slidably installed into the impeller frame through the cooperation of the limiting magnetic block and the mounting chute.

The installation disk 302 is connected to the servo motor 301, and the installation disk 302 is rotationally connected to the impeller frame 1 through the servo motor 301. The internal dimension of the installation through groove 303 matches the external dimension of the installation block 304, and the installation block 304 is connected to the installation disk 302 through the installation through groove 303. The number of blade bodies 305 is set to eight, and the eight blade bodies 305 are evenly distributed outside the installation disk 302. The internal dimension of the threaded through hole 306 matches the external dimension of the installation bolt 307, and the installation bolt 307 is embedded in the installation block 304 through the threaded through hole 306. The servo motor 301 is fixedly installed at the middle of the upper end of the installation frame 2 through screws. The output shaft of the servo motor 301 is connected to the installation disk 302 through a coupling. The operation of the servo motor 301 drives the installation disk 302 to rotate. The internal dimension of the installation through groove 303 opened inside the installation disk 302 matches the external dimension of the installation block 304 provided at the lower end of the blade body 305, so that the blade body 305 is installed outside the installation disk 302 through the cooperation of the installation through groove 303 and the installation block 304. At the same time, the internal dimension of the threaded through hole 306 opened inside the installation block 304 matches the external dimension of the installation bolt 307, so that after the installation block 304 is installed into the installation disk 302, it is fixed and limited through the installation bolt 307, thereby quickly installing the blade body 305, and the appropriate number of blades can be set according to the user's requirements for the wind strength, improving the initiative and practicality during the use of the centrifugal fan.

[0023] As Figure 1 and Figure 3As shown in the figure, a protection component 4 is provided at the front end inside the impeller frame 1. The protection component 4 includes an installation chute 401, a fixed magnet 402, a limit magnet 403, a protection frame 404, and a wedge-shaped net 405. A fixed magnet 402 is additionally provided at the front end inside the installation chute 401, and a limit magnet 403 is connected inside the installation chute 401. A protection frame 404 is provided outside the limit magnet 403. At the same time, a wedge-shaped net 405 is provided inside the protection frame 404.

The wedge-shaped net 405 provided inside the protection frame 404 is used to prevent the staff from accidentally touching the blade body 305 when the centrifugal ventilator is in use. The installation chute 401 is "L"-shaped. Thus, by rotating the protection frame 404, the fixed magnet 402 at the front end of the installation chute 401 is magnetically attracted to the limit magnet 403, thereby quickly disassembling and assembling the protection frame 404 and increasing the convenience during the subsequent use of the centrifugal ventilator.

The internal dimension of the mounting through groove 303 opened inside the mounting disc 302 matches the external dimension of the mounting block 304 arranged at the lower end of the blade body 305. Thus, the blade body 305 is installed outside the mounting disc 302 through the cooperation of the mounting through groove 303 and the mounting block 304. At the same time, the internal dimension of the threaded through hole 306 opened inside the mounting block 304 matches the external dimension of the mounting bolt 307. Thus, after the mounting block 304 is installed into the mounting disc 302, it is fixed and limited through the mounting bolt 307, thereby quickly installing the blade body 305, and the appropriate number of blades can be set according to the user's requirements for the wind strength, enhancing the initiative and practicality during the use of the centrifugal ventilator. Then, the internal dimension of the mounting sliding grooves 401 opened on both sides inside the impeller frame 1 matches the external dimension of the limiting magnetic blocks 403 additionally arranged on both external sides of the protection frame 404. Thus, the protection frame 404 is slidably installed into the impeller frame 1 through the cooperation of the limiting magnetic blocks 403 and the mounting sliding grooves 401. The wedge-shaped net 405 arranged inside the protection frame 404 is used to prevent the staff from accidentally touching the blade body 305 during the use of the centrifugal ventilator. And the mounting sliding grooves 401 are in an "L" shape. Thus, the protection frame 404 is rotated so that the fixed magnetic block 402 at the front end of the mounting sliding groove 401 is magnetically attracted to the limiting magnetic block 403, thereby quickly disassembling and assembling the protection frame 404, increasing the convenience during the subsequent use of the centrifugal ventilator.
