Mixing equipment for fly ash solidification

The mixing equipment for fly ash solidification comprises a mixing barrel, a rotating shaft is movably installed in the mixing barrel, mixing blades are fixedly connected to the outer surface of the rotating shaft, and side edge grooves are formed in the outer surface of the mixing barrel. The side frames are mounted in the side grooves, the middle plates are fixedly connected to the inner surfaces of the side frames in a sleeved mode, the through holes are formed in the side faces of the middle plates, and when mixing blades need to be cleaned, the telescopic rods are started to drive the movable plates to move, so that the sealing rods are moved out of the through holes, and the through holes are opened; after the movable plate moves, an air supply mechanism is started, so that the air supply mechanism introduces high-pressure air into the side frame through a first hole, the mixing blades keep rotating, the annularly distributed through holes spray the high-pressure air towards the rotating mixing blades,
