Description

Technical Field

[0001] The utility model relates to the technical field of fly ash brick making, and more specifically, to a pre-mixing device for fly ash brick making. Background Art

[0002] A large amount of fly ash is generated during the incineration of domestic waste. The main chemical components of fly ash from waste incineration are CaO, SiO2, Al2O3, Fe2O3, SO3, NaCl, KCl, Na2O, and K2O. Fly ash is enriched with dioxins (PCDD / Fs) with high toxic equivalents and heavy metals (Zn, Pb, Cu, Cr, Cd, Ni) with high leaching concentrations. The content of dioxins and heavy metals in fly ash after harmless treatment is significantly reduced, and it can be better utilized as a raw material for building materials. Unburned bricks are bricks that do not require high-temperature calcination. They are a new type of building material formed by the raw materials through oscillation / pressing molding and curing processes.

When making fly ash unburned brick raw materials, the pH value of the fly ash needs to be controlled, but the existing pre-mixing device for fly ash brick making is inconvenient for loading and controlling the pH value of the fly ash.
