Description

Technical Field

[0001] The utility model relates to the field of agitators, and more particularly to a foam concrete stirring device. Background Art

[0002] Foamed concrete is a lightweight material formed by mixing cement, fine aggregate, and a foaming agent. Due to its excellent thermal insulation, low density, and sound insulation, it is widely used in construction, road repair, and foundation treatment. However, the quality and performance of foamed concrete depend largely on the uniformity of the mixed materials and the foaming effect. The quality of the mixing process directly affects the concrete's strength, durability, and workability.

[0003] Most common foam concrete mixing devices currently on the market use a single propeller mixing mechanism. While these devices can achieve a certain degree of initial mixing of the materials, the structural limitations of the propeller itself can easily lead to the formation of "blind spots" within the mixing tank. These blind spots prevent some materials from fully participating in the mixing process, ultimately affecting the density and uniformity of the foam concrete, causing its physical properties to fail to meet expected standards. To ensure the uniformity and quality of foam concrete, overcoming these blind spots is crucial. Summary of the Invention
