▎ 摘　　要

NOVELTY - The device has a hot air blower (13) whose lower end is connected with a first U-shaped conduit (18) and left side is connected with a second L-shaped conduit (19). A front end of the hot air blower is provided with a temperature controller (17). The first and second conduits are connected to an air outlet (20) of the hot air blower. A side of the air outlet is equipped with a temperature sensor (21). An inner part of the hot air blower is equipped with a blower (22). An upper end of the blower is connected with an air inlet (23). A front end of the blower is annularly and equidistantly installed with a spiral heating wire (25). A left side of the blower is provided with a solid relay (26). A back side of the blower is equipped with a motor (24). A side of the motor is provided with a frequency converter (27). An inner part of a small material vehicle is equipped with a material box. An upper end of the small material vehicle is equipped with a dry tower. USE - ODOPB graphene synergetic flame retardant polyamide 6 slice drying device. ADVANTAGE - The device is provided with the first conduit and the second conduit, so that the drying medium nitrogen is divided into two strands entering the tower from the bottom and the middle part of the drying tower, and the nitrogen entering the middle removes the surface moisture of the slices and preheats the slices, and the nitrogen at the bottom removes the residual moisture inside the slice, which can effectively improve the drying efficiency. The device is provided with a temperature sensor at the air outlet of the hot air fan, and one side of the motor is equipped with a frequency converter, so that the user can control the heating temperature, and the air volume is small, which is good for the actual use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an operation method of an ODOPB graphene synergetic flame retardant polyamide 6 slice drying device. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an internal structure of a hot air blower.
