[0033] When cooling the reaction kettle, the cooling liquid in the water storage tank 2 is sent to the cooling cavity 8 through the water inlet assembly 4, and then the driving assembly 13 starts to drive the rotating assembly 10 to make circular motion on the outer side of the reaction kettle 7, so that the mixing assembly 11 and the brush 12 on the rotating assembly 10 rotate. The rotation of the mixing assembly 11 can make the cooling liquid in the cooling cavity 8 uniformly contact the condenser 9 and uniformly cool the outer side of the reaction kettle 7, avoiding local overheating and affecting the cooling efficiency of the reaction kettle 7. The brush 12 rotates to clean the outer side of the reaction kettle 7, avoiding the attachment of impurities on the outer side of the reaction kettle 7 due to long-term soaking in the cooling liquid, which is beneficial to improve the thermal conductivity of the reaction kettle 7 and improve the cooling efficiency.
