NOVELTY - The utility model claims an auxiliary feeding stirring device for preparing high quality graphene oxide, comprising a reaction kettle, an oxidant feeding port, a dilute sulphuric acid feeding port, a discharging port, a temperature measuring probe, a circulating cooling water sleeve, a stirring shaft, a sleeve, a rigid stirring rod and a flexible stirring rope; the stirring shaft is vertically arranged and the upper end extends out of the reaction kettle and is in transmission connection with the output shaft of the motor; two ends of the sleeve are respectively fixedly connected with the stirring shaft and the bottom is sealed; the sleeve is uniformly provided with a plurality of auxiliary feeding micropores; the bottom of the oxidant feeding port and the dilute sulphuric acid feeding port are divided into two paths, one path is respectively connected with an oxidant injector and a dilute sulphuric acid injector; the other path is respectively connected with the upper end of the sleeve. The utility model has simple structure, through two feeding mode, avoids the oxidation process, due to the adding of oxidant and dilute sulphuric acid or water, the material or local temperature is too high, and it can better heat mass transfer, realizing the large-scale preparation of high quality graphene oxide.
