▎ 摘　　要

NOVELTY - The device has a lower shell (2) fixed above a base (1) through a bracket (11). A controller (4) is fixed above the base. The controller is internally provided with a PLC. An upper shell (3) is matched with the lower shell. Supporting mechanisms are positioned at two ends of the upper shell. The upper shell is provided with a first infrared lamp tube (8). The lower shell is provided with a second infrared lamp tube (9). The first and second infrared lamp tubes are electrically connected with the PLC. Driving components are arranged in a driving chamber. The driving components are connected with a closed tube (6) through moving components. USE - Graphene preparing type high-efficient drying device. ADVANTAGE - The upper shell is abutted against the lower shell during drying, so that the first outer red outer lamp tube is used for heating the inner side of the closed tube and the second infrared lamp tube and the third infrared lamp tube are used for heating the outer side of the closed tube, thus improving the drying efficiency and improving the practicability of equipment. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a graphene preparing type high-efficient drying device. Base (1) Lower shell (2) Upper shell (3) Controller (4) Closed tube (6) Infrared lamp tubes (8, 9) Bracket (11)
