Filtering wind wheel of powder concentrator

The invention discloses a filtering wind wheel of a powder concentrator. The filtering wind wheel comprises a wheel body and a shaft sleeve which is arranged in the center of the wheel body. Spokes are connected between the wheel body and the shaft sleeve. A plurality of blades which are parallel to the wheel body in the axial direction are evenly installed on the periphery of the wheel body. Filter gaps are formed between the multiple blades, and included angles are formed between the multiple blades. According to the filtering wind wheel, the multiple blades parallel to the wheel body in the axial direction are evenly installed on the periphery of the wheel body, the filter gaps are formed between the multiple blades, the included angles are formed between the multiple blades, the wind wheel rotates at a high speed, thus, air convection from outside to inside is formed on the side face of the wind wheel through air, powder can enter the wheel body under the action of air flow, the powder which is large in s
