[0003] A Chinese publication number CN217552688U discloses an autoclave for an aerated concrete board. The autoclave of the utility model promotes the accelerated flow of high-temperature steam through the reciprocating sliding of a slider 1 and a slider 2, thereby rapidly raising the temperature inside the autoclave box to reach a target temperature, thereby improving the efficiency of autoclaving of the concrete board.

[0004] In the above technical solution, the first motor and the second motor are used to drive the first screw and the second screw to rotate. The two motors drive the first screw and the second screw, which causes a waste of resources. The first screw and the second screw drive the push shovel to clean and push the bottom skin of the autoclaved aerated concrete block. Since the push shovel can only push the bottom skin of the autoclaved aerated concrete block in one direction, the bottom skin of the autoclaved aerated concrete block can easily spread to both ends when subjected to force, so that the bottom skin of the autoclaved aerated concrete block will fall out of the cleaning platform and cause pollution to the surrounding environment.
