NOVELTY - This utility model claims a purifying device and graphene production system. The purifying device comprises a centrifugal machine, it includes: power source, power transmission unit, drum and filter bag, wherein, the power input end of the power transmission unit and output end of the power source connection, the power transfer unit and power output end and rotate shaft and the drum connected; the filter bag is sleeved on the drum in the spray mechanism, the spraying end extended in the filter bag. The device can be one step to finish purifying process of material, simple and convenient operation, greatly shortening of production period. In addition, material system for comparing large and adhesive, because of only needs on one device in the whole can be complete purification, no transfer to other device, thereby reducing the waste in material transfer process and is beneficial for increasing yield.
