NOVELTY - The utility model claims a graphene redox production device, comprising a reaction box body; the top end of the reaction box body is fixedly connected with a sealing cover through a bolt; the middle part of the sealing cover is slidingly inserted and connected with a main shaft; the top of the main shaft is fixedly inserted with a first sealing plate; two sides of the first sealing plate are provided with a connecting rod; the outer wall of the main shaft is fixedly inserted and connected with a second sealing plate; the upper surface of the second sealing plate is fixedly connected with a second limiting ring; the bottom of the main shaft is fixedly sleeved with a first sleeve; two sides of the first sleeve are fixedly connected with a stirring blade through the bracket. The utility model uses the first sealing plate and the connecting rod matched with the setting mode; the position of the first sealing plate is supported and limited by the connecting rod, so that the main shaft drives the first sleeve to lift upwards to a section of height, so that the stirring blade is separated from the strong acid solution; it is convenient to protect the stirring blade; The service life of the main shaft and the stirring blade is improved.
