    • A kneader/stirrer is provided which has a high self-cleaning ability and can be operated for a long period of time. The kneader/stirrer includes two rotary shafts (4) extending parallel to each other in the processing chamber (2), first regular triangular impellers (3) mounted to one of the rotary shafts (4) so as to be arranged in the axial direction of the rotary shaft (4), and second regular triangular impellers (3) mounted to the other rotary shaft (4) at the same axial positions as the respective first impellers (3). The impellers (3) are fixed to the respective rotary shafts (4) at points offset from the centers of the respective impellers (3) in a predetermined direction by a predetermined distance such that when the two rotary shafts (4) rotate in the same direction at the same speed, each pair of first and second impellers (3) are eccentrically pivoted, with one apex of one of the pair of impellers kept in contact with or in close proximity to the contour of the other impeller, thereby scraping off polycondensation resin (material to be processed) adhered to the other impeller, while scraping off resin adhered to the inner wall of the processing chamber (2) with one of the apexes nearest to the inner wall. Thus, this device has a higher self-cleaning ability than conventional devices using disk-shaped impellers, and thus can be stably operated for a long period of time.
    • 提供了具有高自清洁能力并可长时间操作的捏合机/搅拌器。 捏合机/搅拌机包括在处理室(2)中彼此平行延伸的两个旋转轴(4),安装在一个旋转轴(4)上的第一规则三角形叶轮(3),以沿轴向方向 以及在与第一叶轮(3)相同的轴向位置处安装到另一旋转轴(4)的第二规则三角形叶轮(3)。 叶轮(3)在预定方向上偏离各叶轮(3)的中心的点处固定到相应的旋转轴(4)上预定距离,使得当两个旋转轴(4)在同一旋转轴 方向以相同的速度,每对第一和第二叶轮(3)偏心地枢转,一对叶轮中的一个叶轮的一个顶点与另一个叶轮的轮廓保持接触或非常接近,从而刮除缩聚 树脂(待处理材料)粘附到另一个叶轮上,同时用最靠近内壁的顶点之一刮去附着在处理室(2)的内壁上的树脂。 因此,该装置具有比使用盘形叶轮的常规装置更高的自清洁能力,因此可以长时间稳定地操作。
