▎ 摘　　要

NOVELTY - The machine has a shell (1) whose left side is provided with a freeze-drying device. A right side of the shell is connected with a crushing mechanism. A bottom end of the crushing mechanism is provided with a cleaning mechanism. A bottom end of the cleaning mechanism is provided with a telescopic bracket. A bottom end of the telescopic bracket is provided with a collecting box (6). An upper half section at a top end of the telescopic bracket is fixedly connected with a grinding bowl. An arc-shaped micro-elastic crushing rod is provided with a baffle block. A bottom end of a strip-shaped electromagnetic frame is fixedly connected with an arc-shaped micro-elastic stirring rod. USE - Graphene oxide vacuum freeze-drying machine. ADVANTAGE - The machine utilizes the crushing mechanism to crush freeze-dried graphene oxide to avoid contact with air and to prevent oxidation and deterioration in an effective manner. Prevents graphene oxide powder in the grinding bowl from extreme pouring on the arc-shaped micro-elastic crushing rod so as to avoid graphene powder deterioration caused by prolonged long time air contact, so that resource wastage is reduced in an effective manner. Extends the cleaning bag along with rotation of the rotating disk so as to clean an inner wall of the grinding bowl in a convenient manner. DESCRIPTION OF DRAWING(S) - The drawing shows a top perspective view of a graphene oxide vacuum freeze-drying machine. Shell (1) Collecting box (6) Automatic valve (207) Connecting pipe (301)
