PURPOSE:To obtain a stirrer having high efficiency, by providing axial flow type shearing parts each consisting of a turbine and a stator to the upper and lower parts of a stirring shaft and flowing a fluid in a state opposed from above and below. CONSTITUTION:A turbine 4 is fixed to the lower part of a stirring shaft 2 and a stator 5 connected to fixing rods 6 is arranged to the outside of said turbine 4 to form an axial flow type shearing part 3 while a turbine 8 and a stator 9 are provided to the upper part of the stirring shaft 2 in the same way to form an axial flow type shearing part 7. In this constitution, the lower axial flow type shearing part 3 applies flowing action to a fluid from the lower part to the upper part and the upper axial flow type shearing part 7 applies flowing action thereto from the upper part to the lower part. Whereupon, fluid streams collide at the intermediate part to generate turblent flow and, therefore, stirring efficiency is markedly enhanced. Further, the interval between the axial flow type shearing parts 3, 7 may be made adjustable by arbitrarily moving the turbine 8 and stator 9 of the upper axial flow type shearing part 7 up and down to fix both of them. |
