Description

[0002] With the acceleration of urbanization and the optimization of energy structure, the amount of fly ash produced by coal-fired power plants and waste incineration power plants is increasing year by year; the resource utilization of fly ash, especially as an admixture for preparing concrete, mortar or non-burning building materials, has become an important way to realize solid waste reduction, harmlessness and resource utilization.

[0003] In the fly ash building material production process, the key process to determine the uniformity and performance stability of the final product is to fully mix fly ash with other raw materials (such as cement, aggregate, activator, etc.) in the mixing equipment. Fly ash is an extremely fine powder particle (particle size is mostly 1-100 μm), which has the characteristics of small density, strong fluidity, large specific surface area, and easy to generate static electricity. Therefore, when fly ash is added to the mixing equipment and falls into the mixing cylinder at high speed from the feeding port, the height difference of the falling and the violent disturbance with the air in the cylinder can easily produce a large amount of flying dust, causing part of the fly ash to fly out of the mixing equipment, or to splash to the upper space of the mixing equipment or to adhere to the inner wall of the mixing cylinder, mixing arm, cover plate and other parts, forming a "wall hanging" phenomenon, causing raw material waste, reducing the utilization rate of fly ash, and increasing the production cost. In addition, the fly ash adhered to the inner wall is difficult to be effectively scraped off and involved in the mixing in the subsequent batches, resulting in inaccurate proportioning, decreased mixing uniformity, and affecting the strength and durability of the building material product.
