  • Publication number: 20200353482
    Abstract: The disclosure discloses wet electrostatic classification device for ultrafine powder based on rotating flow field, which belongs to the field of ultrafine powder classification equipment. The wet electrostatic classification device for ultrafine powder of the disclosure includes a cylinder body. The cylinder body is a hollow cavity. A material conveying shaft and a rotating shaft are disposed in the cylinder body. Outlets are formed in a circumferential wall of the cylinder body. A deceleration motor is mounted on the lower end through a machine frame. First electrode pieces are disposed on an inner wall. The spray head is mounted between the material conveying shaft and the rotating shaft. The rotating shaft is connected to the deceleration motor through a coupling. Second electrode pieces are disposed on outer walls of the material conveying shaft and the rotating shaft. The spray head is configured to spray a material into the cylinder body to form a rotating flow.
