AI Technical Summary

Technical Problem

In existing flame retardant drying equipment, the flame retardant at the bottom of the drying drum does not come into sufficient contact with the hot air, resulting in poor drying effect.

Method used

It adopts components such as a transmission rod, brake motor, heating resistor, electric telescopic rod, notched drying cylinder, sleeve and feeding blades. Through synchronous rotation and feeding blades contacting the material, it ensures that the material is in full contact with the hot air, thereby improving the drying effect.

Benefits of technology

This method achieves uniform drying of the flame retardant, improves drying efficiency and effectiveness, avoids material sticking, and enhances the drying effect of the flame retardant at the bottom.
