Description

Technical Field

[0001] This utility model relates to the field of building material processing technology, specifically to a pre-curing device for concrete block blanks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a lightweight, porous building material made from siliceous materials (such as quartz sand and fly ash), calcareous materials (such as lime and cement), a foaming agent (such as aluminum powder), and water through processes such as mixing, pouring, foaming, cutting, and autoclaving.

[0003] In response to this, the utility model patent with announcement number CN201720928U discloses a curing device for aerated concrete block blanks, including a curing chamber (1). The device is characterized in that: a guide rail (3) for loading concrete block blanks and allowing a sliding rail trolley (5) to slide is provided on the ground of the curing chamber (1). The guide rail (3) is connected to the guide rail of the blank feeding workshop and the ground guide rail for entering the autoclave.

[0024] Movable casters 502 are fixed at the four corners of the bottom of the movable plate 501. Two movable casters 502 are inserted into each guide groove 4. A handle 503 is fixed at one end of the movable plate 501. A connecting diagonal bar 6 is fixed at one end of the base 1. An electric cylinder 8 is installed on one side of the top of the curing box 2. An L-shaped drive rod 9 is fixed at the output end of the electric cylinder 8.
