Description

Technical Field

[0001] The utility model relates to the technical field of foaming machines, in particular to a foaming machine for foam concrete. Background Art

[0002] The foaming machine for foam concrete is a key device for producing foamed cement and foam concrete. Its main function is to mix a specific foaming agent with water, and through mechanical action, a large amount of foam is generated, which is then mixed with concrete to form lightweight and well-insulated foam concrete.

[0003] After retrieval, a Chinese utility model patent with the publication number CN214725307U, titled "A device for foaming foam concrete", includes a foaming bin. A motor is fixedly installed at the bottom of the foaming bin. A transmission rod is fixedly installed in the middle of the motor. A first gear is fixedly installed at the outer end of the transmission rod. The outer end of the first gear meshes with a gear block. The right end of the gear block meshes with a gear groove. The gear groove is arranged on the inner wall of a rotating ring. The bottom of the rotating ring is movably connected to the foaming bin. A discharge port is opened at the lower right side of the foaming bin. Through the coordinated use of the transmission rod, the gear block and the rotating ring, the mixing of the cement slurry and the foaming agent by the stirring rod is more uniform.

[0004] However, it is found in the use process that when foaming foam concrete, in addition to the foaming agent and water, gel materials such as cement, fly ash and mineral powder are also indispensable. These raw materials are the basis for forming the skeleton of foam concrete. During the production process, it is found that the size of some raw materials is relatively large. When the raw materials with larger sizes are mixed with the foaming agent and water, there are great difficulties, resulting in uneven mixing, which in turn affects the foaming effect of foam concrete. The raw materials with larger sizes make the particle size of foam concrete poor. The unevenness of the particle size not only affects the strength and density of foam concrete, but also may lead to a decline in the quality and service performance of foam concrete, which is not conducive to the foaming and use of foam concrete.
