AI Technical Summary
The problem with existing technologies is uneven drying of magnetic powder, especially the small amount of hot air contacting the magnetic powder at the bottom, which results in poor drying effect.
A drive motor rotates the support plate, and a water pipe connected to the support plate stirs the magnetic powder. A heating rod heats the water in the water pipe to ensure uniform drying. At the same time, a staggered second water pipe is set up to increase the stirring range, and an insulation layer is added to the outside of the drying box to reduce heat loss.
This method achieves uniform drying of magnetic powder, improves drying efficiency and effectiveness, and reduces heat loss.
