[0010] Beneficial effects

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: An auxiliary device for a defoamer that can cool down and discharge steam. By adding a protective shell outside the drive shaft and arranging a cooling fan on the part of the drive shaft located in the inner cavity of the protective shell, when the drive shaft rotates, it will drive the cooling fan to rotate, forming an air flow in the protective shell, exchanging heat with the drive shaft, taking away the heat on the drive shaft, reducing the temperature, and thus avoiding heat conduction to the motor and causing the motor to overheat. Through a plurality of ventilation holes for air intake and exhaust, the air in the inner cavity of the protective shell can flow and exchange with the outside air, exhausting the hot air and allowing the cold air to enter the inner cavity of the protective shell.
