[0025] It should be noted that, since the existing flame retardant raw material drying device is prone to uneven drying during the drying process, the flame retardant raw material lacks turning, and the flame retardant raw material is unevenly heated, which affects the drying efficiency.

The turning of the inner heating cover 8 facilitates the discharge of the flame retardant raw material under turning.

[0026] Specifically, in the present embodiment, the present scheme mainly comprises an outer drum 3, an outer heating cover 7 and an inner heating cover 8. When in use, the feed valve 5 is opened, the flame retardant raw material is injected into the inner part of the outer drum 3, the feed valve 5 is closed, the external power supply is turned on, the electric heating tubes 15 inside the outer heating cover 7 and the inner heating cover 8 are energized to generate heat, the servo motor 2 drives the outer drum 3 to rotate through the output end on one side thereof, the flipping plate 4 on the inner side wall of the outer drum 3 moves axially synchronously, the flipping plate 4 flips the flame retardant raw material upward, and the flame retardant raw material moves from bottom to top during the flipping process, and finally the flame retardant raw material falls from top to bottom between the outer heating cover 7 and the inner heating cover 8, and the flame retardant raw material is between the outer heating cover 7 and the inner heating cover 8. It is heated and dried, and the flame retardant raw material is uniformly heated and dried by repeatedly turning over. After the flame retardant raw material is dried, the stepper motor 10 is controlled to drive the gear 11 to rotate through the output end on one side thereof, and the gear ring 9 drives the inner heating cover 8 to rotate synchronously through the meshing connection between the gear 11 and the gear ring 9, and the inner heating cover 8 is controlled to rotate 180 degrees, and the through groove 13 on the outer wall of the inner heating cover 8 is rotated to an upward position.
