Air-sealed star unloader is used to install in the discharge port of the unloader working under negative pressure, the upper part accepts the material discharged from the unloader, and relies on the rotating impeller to play the role of conveying materials, and also plays the role of sealing to prevent the air from being sucked in from the discharge port in the process of pneumatic conveying to ensure the normal discharge of the unloader.
It adopts a closed rotor, which can be widely used in suction conveying, pressure conveying, airflow conveying systems, and negative pressure conveying equipment, which can ensure that the airflow pressure in the conveying pipe does not leak to safely convey and receive materials.
