PURPOSE:To dispense with a mount seat and an adaptor, by arranging a flow direction altering plate having one or plural flow direction altering blades for flow direction of an emitting stream in close vicinity to the emitting side of the stirring blade, which generates the emitting stream in the axial direction, of a stirrer. CONSTITUTION:The flow direction of the axially directed emitting stream generated by a stirring blade 13 is altered to a leftward oblique direction with respect to a rotary axis 15 at the sight from the part above a stirring tank 11 as shown by the arrow by a flow direction altering plate 18. As a result, a stirring stream having a conventional pattern, such that the rotary axis 15 of a stirrer 14 is inclined with respect to the diameter line 5 of the stirring tank 11, can be obtained. The flow direction altering plate 18 may be arranged only by fixing said plate 18 over again by changing the angle of inclination or rotary angle with respect to the rotary axis 15 and the work thereof is easy. Flow direction altering blades 17 are vertical and mutually parallel and arranged so as to be inclined with respect to the rotary axis 15 of the stirrer 14. |
