Description

Technical Field

[0001] This utility model relates to the field of steam curing equipment, and in particular to a steam curing equipment for aerated brick production. Background Technology

[0002] Aerated concrete blocks, also known as autoclaved aerated concrete blocks, are a new type of wall material made from stone powder, cement, and lime as the main raw materials. They are prepared by casting, cutting, and curing under high pressure with steam. They are mainly used for non-load-bearing wall construction and frame structure filling. They are lightweight materials promoted and applied in key industrial and civil fields by the Ministry of Construction and the State Science and Technology Commission.

[0003] In the process of aerated concrete block manufacturing, steam curing equipment is used to perform high-pressure steam curing on the aerated concrete block blanks. After steam curing is completed, the autoclave lid needs to be opened to send the aerated concrete blocks out. However, the current steam curing equipment cannot utilize the steam in the autoclave lid, and the steam is directly discharged into the air, which easily leads to the waste of heat energy and poor energy-saving effect.

[0004] Therefore, a steam curing device for aerated concrete block production is proposed to solve the above problems. Utility Model Content

[0037] Working principle: The user first feeds the aerated concrete blocks into the autoclave 1 through the conveying equipment, then closes the sealing cover 2, which seals the autoclave 1. Then, the external steam equipment sends steam into the autoclave 1 to cure the aerated concrete blocks. After curing, the motor 4 is started and the sealing cover 2 is opened. The motor 4 drives the fan blade 9 to rotate. After the sealing cover 2 is opened, the high-temperature steam will float out. The motor 4 will drive the L-shaped rod 11 to rotate through the reducer 10. The fan blade 9 draws the high-temperature steam through the air duct 5 and the perforated sleeve 6, allowing the high-temperature steam to enter the heat conduction pipe 7. The heat conduction pipe 7 transfers the heat of the high-pressure steam into the water inside the water tank 3. The L-shaped rod 11 drives the toothed rod 12 to rotate. Since the toothed rod 12 meshes with the toothed ring 13, the toothed rod 12 will rotate and agitate the water, facilitating heat exchange between the water and the heat conduction pipe 7. The user can use hot water through the valve pipe 8, and can also send hot water into the external steam equipment for use, thereby achieving the effect of waste heat utilization.
