    摘要： A hollow shaft of a screw conveyor for transporting powder material receives pressurized air in its interior. A plurality of openings through the wall of the hollow shaft permits the pressurized air to exit energetically to prevent build-up of the powder material on the inside wall of the casing of the screw conveyor. In one embodiment, the openings are slits angled with respect to the axis of the screw conveyor at about the same angle as the helical blade. This produces a swirling flow of air which, in addition to preventing build-up of materials, enhances the advance of the powder material and, when the powder material is a mixture of different materials, helps prevent separation of the materials during transport.

    摘要翻译： 用于输送粉末材料的螺旋输送机的空心轴在其内部接收加压空气。 通过空心轴的壁的多个开口允许加压空气能力地离开以防止粉末材料在螺旋输送机的壳体的内壁上积聚。 在一个实施例中，开口是以与螺旋叶片大致相同的角度相对于螺旋输送器的轴线成角度的狭缝。 这产生旋转的空气流，除了防止材料积聚之外，还增加了粉末材料的进展，并且当粉末材料是不同材料的混合物时，有助于防止在运输过程中材料的分离。
