    • A mixer impeller having high efficiency blades (24). The impeller may include a central hub (14) and a plurality of blades attached to and extending radially outwardly from the hub such that leading edges (38) thereof are inclined upwardly from trailing edges (50) thereof. Each of the blades may include a root (26) attached to the hub, a tip (28), a first crease (32) extending along substantially an entire length of the blade dividing the blade into a leading portion (34) and a trailing portion (36), the leading and trailing portions meeting at the first crease such that the leading portion is angled downwardly from the trailing portion, and a second crease (40) extending from a portion of the leading edge of the leading portion between the root and the tip diagonally along the leading portion to the tip, the second crease intersecting the tip at a point spaced from a point where the first crease intersects the tip, the second crease forming a tip portion of the leading portion that needs a remainder of the leading portion such that the tip portion is angled downwardly from the leading portion.
    • 一种具有高效叶片(24)的搅拌机叶轮。 叶轮可以包括中心轮毂(14)和多个叶片,其连接到轮毂的径向向外并从轮毂径向向外延伸,使得其前缘(38)从其后缘(50)向上倾斜。 每个叶片可以包括附接到轮毂的根部(26),尖端(28),沿刀片的大致整个长度延伸的第一折痕(32),所述第一折痕将刀片分割成前导部分(34)和尾部 所述前部和后部在所述第一折痕处相交,使得所述前部从所述后部向下成角度;以及第二折痕(40),其从所述前端部的所述前缘部的所述前缘的一部分延伸到所述根部 并且所述尖端沿着所述尖端的前导部分对角地,所述第二折痕在与所述第一折痕与所述尖端相交的点间隔开的点处与所述尖端相交,所述第二折痕形成所述引导部分的尖端部分,其需要剩余部分 引导部分,使得尖端部分从引导部分向下成角度。
