▎ 摘 要
NOVELTY - The utility model claims an oxidation graphene washing grading device, comprising the first liquid storage tank, the second liquid storage tank, water pump, separating pool, electric board and voltage control system. Said first upper liquid storage tank is set with water port for valve and the first water outlet valve for washing and grading of the oxidation graphite alkene solution through water inlet valve to the first liquid storage pool. Upper and lower end of separating pool is equipped with power board, the voltage control system is connected with electric board electrical property to form strong mixing power site in electric board. Comparing to the existing technology, the oxidation graphene washing grading device of the utility model uses theory of electrophoresis and the oxidation graphene and in electrification electric field because of electric force site to appear delamination finishes washing for the oxidation graphite alkene solution at low applied electric field effect, removes impurity ion, washes oxidation graphite alkene solution and mass different theory of saving time, increases production efficiency, uses different size oxidation graphene in electric field and by the electric force site and realizes classification of different size oxidation graphene through regulating voltage.
