<p>A fluid stirrer in which a power unit and a bearing unit are provided in a sealed space, to agitate the fluid in the space without permitting it to leak out of the equipment. When an electric motor is used as a power unit, only the stator winding of the motor that poorly endures a high-temperature and wet atmosphere is accommodated in a sealed container and, if necessary, provision is made of a cooling device to forcibly cool the sealed container. The driving shaft of the motor is supported by a bearing that withstands high temperature and humidity, and is further provided with stirring vanes. When a turbine is used as a power unit, a turbine casing and turbine blades are arranged in a sealed space, a fluid to turn the turbine blades is supplied by a fluid supply device from outside the sealed space, and the turbine blades are equipped with stirring vanes via a rotation transmission device.</p> |
