Agitated reactor

The utility model provides an agitated reactor, includes the cauldron physically, the external side of cauldron is equipped with outer cooling jacket, cauldron body top is equipped with inverter motor, inverter motor and retarder connection, and the reduction gear below is connected with agitating unit, and it is internal that agitating unit is located the cauldron, be equipped with the draft tube between the cauldron body and the agitating unit, be equipped with interior cooling jacket outside the draft tube, interior cooling jacket's bottom and the top is connected with the cooling water inlet tube respectively and the cooling water outlet pipe extends to the external portion of cauldron. The beneficial effects of the utility model are that inverter motor can change the slewing radius that the horizontal sliding overlaps through centrifugal force at the during operation, and its stirring effect is better, internal portion adds draft tube and interior cooling jacket at the cauldron, and the temperature that not only can improve harmony, the especially (mixing) shaft peripheral region of the internal distribution of temperature of cauldron greatly is harmonious, in addition, the draft tube designs into dolioformly, can make the reactant form the torrent, makes the reaction even more and abundant.
