NOVELTY - graphene for automatic washing and vacuum filtering sieve. Currently, the widely used graphene filter sieve device, reaction kettle is made of stainless steel or glass material, the cost is high, and the operation is not convenient, especially change nano screen (screen filter membrane), and troublesome and takes time, low production efficiency and the production cost is increased. The utility model comprises a frame (1), the machine frame is mounted with a cylinder (2), lifter (3) and the lifter can control opening and closing of vacuum chamber and cleaning stirring barrel, so as to change the sieve, the cylinder is connected with the vacuum chamber (4) connection. the vacuum cabin and the stirring barrel (5) is provided with a nano-sieve (6), the vacuum chamber and the hopper (7) connecting the cleaning stirring barrel part and the high pressure air inlet (8) connecting the hopper bottom of the high pressure wind blowing port (9) connection. The utility model is used for washing graphene.
