This utility model discloses an autoclaving device for curing fly ash bricks, relating to the technical field of fly ash brick production equipment. It includes an autoclaving device body, a sealing door on the front surface of the body, a support frame on the inner surface, and sliding guide rails on both sides of the upper surface of the support frame. A curing box is slidably mounted on the inner surface of the sliding guide rails, and multiple ventilation slots are formed on both sides of the curing box. A handle is provided on the rear surface of the curing box. Compared with existing ordinary autoclaves for fly ash brick production, this autoclaving device for curing fly ash bricks, through the setting of threaded rods, allows multiple threaded rods to rotate synchronously via a servo motor. This drives a guide slider to slide upward along a limiting groove, lifting the placement plate containing the bricks from inside the curing box, facilitating the loading and unloading of bricks and improving the curing efficiency of fly ash bricks.

The utility model discloses an unmanned operation watering concrete curing cooling device which comprises a water level sensor, two water tanks and a controller, the controller is connected with electricity, the water level sensor is installed in the water tanks, and when the water level sensor detects that the water level in the water tanks is insufficient, watering operation is stopped. The water level sensor is installed in one water tank, a hose is detachably installed between the bottoms of the two water tanks, a support structure is installed between the water tanks at the two ends, and the two water tanks are located on the same diameter line of the fan tower base and located on the outer side of the fan tower base respectively during use. A rotary spraying device is installed through the support structure, the controller is connected with and controls the rotary spraying device, and the rotary spraying device takes water from the water tanks at the two ends. The device is convenient to maintain and uniform in maintenance, and leakage points are avoided.
