[0029] like Figure 1-4As shown, the raw material grinding and powder selection device described in the embodiment of the present application includes a shell 1, a cage rotor 2 and a collecting hopper 3. The cage rotor 2 is rotatably arranged inside the shell 1, and the collecting hopper 3 is fixedly installed inside the shell 1. The cage rotor 2 is located above the collecting hopper 3. A discharge port 4 is arranged at the upper end of the side of the shell 1, and a motor 5 is arranged at the upper end of the shell 1. A rotating shaft 6 is arranged at the output end of the motor 5. The rotating shaft 6 penetrates the shell 1 and extends to the inside of the shell 1. The rotating shaft 6 is fixedly connected to the cage rotor 2. A support rod 7 is arranged at the bottom of the cage rotor 2, and a brush 8 is arranged on the support rod 7. A screen 9 is arranged inside the collecting hopper 3, and the brush 8 abuts against the screen 9 for cleaning the screen 9.

[0030] When in use, the motor 5 drives the cage rotor 2 to rotate through the rotating shaft 6. The cage rotor 2 forms a high-speed upward airflow to bring the crushed material into the collecting hopper 3. The screen 9 screens the material. The material that meets the particle size requirements passes through the screen 9, and the material that does not meet the particle size requirements is screened out. When the cage rotor 2 rotates, the support rod 7 and the brush 8 rotate synchronously. The brush 8 cleans the screen 9 during the rotation process to avoid clogging of the screen holes of the screen 9, thereby ensuring the screening effect and screening efficiency of the screen 9, reducing the frequency of shutdowns for maintenance, and improving production efficiency.

[0031] In this embodiment, a connecting ring 10 is provided at the bottom of the cage rotor 2, and the end of the support rod 7 is fixedly connected to the connecting ring 10. The connecting ring 10 extends to the interior of the collecting hopper 3. The connecting ring 10 abuts against the inner wall of the collecting hopper 3, and the upper end of the collecting hopper 3 abuts against the cage rotor 2, thereby improving the stability of the operation of the cage rotor 2.

[0032] In this embodiment, the brush 8 and the support rod 7 are detachably connected to facilitate replacement of the brush 8 .

[0033] In this embodiment, a plurality of support blocks 11 are disposed at the lower end of the screen 9 . The support blocks 11 are fixedly disposed inside the collecting hopper 3 , and are used to support the screen 9 .

[0034] In this embodiment, the screen 9 and the support block 11 are detachably connected to facilitate the disassembly of the screen 9 .

[0035] The working principle of a raw material grinding and powder selection device in the embodiment of the present application is as follows:

[0036] When in use, the motor 5 drives the cage rotor 2 to rotate through the rotating shaft 6. The cage rotor 2 forms a high-speed upward airflow to bring the crushed material into the collecting hopper 3. The screen 9 screens the material. The material that meets the particle size requirements passes through the screen 9, and the material that does not meet the particle size requirements is screened out. When the cage rotor 2 rotates, the support rod 7 and the brush 8 rotate synchronously. The brush 8 cleans the screen 9 during the rotation process to avoid clogging of the screen holes of the screen 9, thereby ensuring the screening effect and screening efficiency of the screen 9, reducing the frequency of shutdowns for maintenance, and improving production efficiency.

[0037] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
