When the temperature in the shell 1 rises due to the violent reaction of the raw materials in the inner wall 11 of the reaction kettle and reaches the temperature set by the temperature sensor 21, the fan 3 will be turned on at this time. The opening of the baffle on the side of the air inlet 2 caused by the opening of the fan 3 allows the air inlet 2 to suck in external cold air into the shell 1, thereby cooling the inner wall 11 of the reaction kettle in the shell 1. When the temperature of the inner wall 11 of the reaction kettle drops, the fan 3 will be turned off, and the baffle on the side of the air inlet 2 will be closed, so that external air cannot enter to achieve the heat preservation effect.
