▎ 摘　　要

NOVELTY - This utility model belongs to graphene preparation field, claims a graphene oxide powder drying and collecting device, the device is mainly provided with a first drying kettle and the second aggregate kettle body specifically comprises: high pressure inlet, a low pressure inlet, a feeding port, a feeding vibration sieve; the waste collecting port, an insulating shell, a filter screen, a discharging port, a vent with a filter core, the trapezoidal connection channel, a discharging vibration sieve. The utility model can effectively realize the drying at low temperature, avoids oxidization graphene because of too high temperature causes partial loss of oxygen-containing functional groups, and collecting the graphene oxide is fine powder, which is more helpful for dispersing and further use.
