    • A mixing system for mixing fluids or the like in a mixing vessel. The mixing system includes a fixed conduit connected to the top portion of the vessel extends into the vessel. The system also has a rotating shaft 12 having disposed within the fixed conduit that rotates within the fixed conduit while the mixing system is in operation. An impeller 10 is attached to the rotating shaft 12. The impeller blade has a flat central disk portion 24, at least a pair of extensions 26 extending from a central disk portion, and at least two leading edges 30 defined by the outer periphery of the disk portion. Each leading edge 30 spans from one extension to an adjacent extension, and each leading edge 30 has at least a portion at which the radius of the leading edge from the center increases to form a continuous increasing radius curve. Each leading edge forms an increasing radius spiral edge surface in between the extensions.
    • 用于在混合容器中混合流体等的混合系统。 混合系统包括连接到容器顶部的固定导管延伸到容器中。 该系统还具有旋转轴12,旋转轴12设置在固定导管内,在混合系统运行的同时在固定管道内旋转。 叶轮10附接到旋转轴12.叶轮叶片具有平坦的中心盘部分24,至少一对从中心盘部分延伸的延伸部分26以及至少两个前缘30, 磁盘部分。 每个前缘30从一个延伸部延伸到相邻的延伸部,并且每个前缘30具有至少一部分,前缘的中心半径从该中心增加以形成连续增加的半径曲线。 每个前缘在延伸部之间形成增加的半径的螺旋边缘表面。
