    • In a stirring device of liquid material, of circulation type comprising a return pipe inserted in a stirring tank, and a feeding pipe connected to bottom portion of the stirring tank, so that the liquid material fed through the feeding pipe is returned to the return pipe, an expanded part having inner diameter larger than that of the return pipe is provided at top end of the return pipe, and plurality of holes having the total opening diameter larger than the lateral sectional area of the return pipe are bored on both sides of outer circumferential portion of the expanded part. Two reverse circulation streams in the horizontal direction are formed within the circulation tank, and the liquid material is circulated through the feeding pipe and the return pipe, thereby the stirring is performed well without involving the excessive air.
    • 在液体材料的搅拌装置中,包括插入搅拌槽中的回流管的循环型搅拌装置和与搅拌槽的底部连接的进料管,使得通过供给管供给的液体材料返回回流管 在返回管的顶端设置内径大于返回管的内径的扩大部分,并且具有大于回流管的横截面面积的总开口直径的多个孔在外侧的两侧钻孔 膨胀部的圆周部。 在循环箱内形成水平方向的两个反向循环流,液体材料通过进料管和回流管循环,从而在不引起过量空气的情况下进行搅拌。
