Full-automatic drainage system and method for aerated concrete plate steam curing kettle

The invention relates to a full-automatic drainage system of an aerated concrete plate steam-curing kettle, which comprises a steam-curing kettle mechanism, a guide mechanism and clamping mechanisms, the guide mechanism is provided with a plurality of groups of clamping mechanisms in an array manner along the transmission direction of the guide mechanism, and after the plurality of groups of clamping mechanisms respectively clamp concrete blanks to enter the steam-curing kettle mechanism, the steam-curing kettle mechanism is driven by the guide mechanism to rotate; the concrete blanks are gradually conveyed forwards along the guide rail assembly under the driving of the guide mechanism, and the different concrete blanks are arranged in the different clamping mechanisms respectively, so that the concrete blanks are not stacked any more, high-pressure steam in the steam curing kettle mechanism can be fully in contact reaction with the different concrete blanks, and the concrete blanks are uniformly mixed.
