    • Disclosed is an agitating device (3) to be disposed in a batch-type vessel or the like. The agitating device (3) has an upper cover plate (5), a bottom cover plate (6), an impeller (7), an inner screen member (8), and first and second outer screen members (9, 10). When a mixed liquid including a dispersoid and a dispersion medium passes through liquid communication holes (19) of the inner screen member (8) and liquid communication holes (22, 25) of the outer screen members (9, 10) during the course where it flows outward from the impeller (7) to get out of an interplate space, the circumferential component of the flow vector of the mixed liquid is mostly eliminated to allow the mixed liquid to have substantially only the radial component. This prevents the generation of vortexes so as to apply a sufficiently high shearing force to the mixed liquid to effectively prevent the formation of macro bubbles in the mixed liquid.
    • 公开了一种设置在间歇式容器等中的搅拌装置(3)。 搅拌装置(3)具有上盖板(5),底盖板(6),叶轮(7),内筛部件(8)以及第一和第二外筛部件(9,10)。 当包含分散质和分散介质的混合液通过内筛部件(8)的液体连通孔(19)和外筛部件(9,10)的液体连通孔(22,25)时,其中 它从叶轮(7)向外流出以离开板间空间,混合液体的流动向量的圆周分量大部分被消除,以使混合液体基本上仅具有径向分量。 这防止产生涡流,从而对混合液施加足够高的剪切力,以有效地防止在混合液体中形成大气泡。
