Description

Technical Field

[0002] Aerated bricks, also known as "autoclaved aerated concrete blocks", are aerated concrete blocks produced by high-temperature autoclaving equipment. Aerated bricks have the advantages of light weight, good thermal insulation, strong earthquake resistance and good processing performance, and are now being used more and more widely.

[0003] In the production process of aerated bricks, the slurry that has been stirred and mixed in the slurry tank needs to be injected into the aerated brick mold box. Since the position of the discharge pipe is fixed relative to the mold box, the mold box can only be evenly filled with slurry by slowly filling the mold box with slurry under its own gravity. However, the volume of the aerated brick mold box in the current production process is often relatively large, and the speed at which the slurry fills the mold box under its own gravity is very slow, which greatly limits the efficiency of aerated brick casting production. At the same time, pouring slurry directly from the discharge pipe into the aerated brick mold box can easily mix air into the slurry, forming large bubbles in the aerated brick, which seriously affects the product quality.
