[0036] Working principle: when drying the powder used in metallurgical engineering, first start the electric heating wire 13 and the motor 3. After the motor 3 is started, it can drive the fan 4 to rotate, and after the output end of the motor 3 rotates, it can drive the driving shaft 5 to rotate through the belt.
