[0002] With the rapid development of industrial technology, magnetic powder, as an important industrial raw material, has been widely used in electronics, communications, automobiles, aerospace and other fields. In the production and use of magnetic powder, drying of magnetic powder is an indispensable link. Usually a drying drum is required. During the rotation process, the magnetic powder is pushed and dried, and then the hot air is blown to the magnetic powder, so that the magnetic powder is quickly dried during the process of the drying drum's diversion and pushing, so as to achieve the magnetic powder drying effect.

[0003] Traditional magnetic powder drying devices usually adopt horizontal long-cylinder drying to push and dry the magnetic powder inside during the rolling process. However, in actual use, the overall drum rolling consumes a lot of energy. At the same time, hot air is introduced from one end and then exported from the other end. Its overall heat energy retention capacity is weak, the hot air circulation effect is insufficient, the energy consumption is relatively high, the drying effect is relatively general, and long-term drying is required. For this reason, we propose an energy-saving magnetic powder drying device to solve the above problems. Utility Model Content

Those skilled in the art can easily implement it. It belongs to the existing technology and will not be elaborated.

[0047] Working principle: by arranging a conical screen 2 and a conical lower hopper 3 in the drying tank body 1, after the magnetic powder enters the drying tank body 1 from the feed hopper 12, it is carried by the conical screen 2, and then screened and filtered, and then screened by the conical lower hopper 3.

The exhaust gas discharge pipe 10 has a long pipeline and small heat loss. At the same time, a temperature sensor 11 is arranged inside the drying tank body 1, and is located at the bottom of the tank body, so as to accurately sense the temperature change in the tank body. When the temperature is high, the operation of the drying electric heating wire 9 and the blowing motor 8 can be stopped, so as to further reduce the energy consumption, so that the device can achieve the hot air circulation drying capacity, the thermal energy cycle is stable, the energy saving effect is good, and the drying efficiency is high, so as to solve the problems of the existing horizontal drum drying method, the poor drying hot air circulation capacity, the relatively high energy consumption, the general drying effect, and the need for long thread and long time drying.
