Continuous production method for preparing cast stone plate from waste incineration fly ash

Abstract

The invention provides a continuous production method for preparing a cast stone plate by utilizing waste incineration fly ash, which comprises the following steps: firstly, treating the waste incineration fly ash, feeding the treated waste incineration fly ash into a fly ash bin, adding ingredients, granulating, stably discharging, quickly melting the fly ash in a melting cavity to form a mineral solution, discharging an additional product, and cooling to obtain the cast stone plate. The method comprises the following steps: melting a high-temperature melting device to form a mineral solution output to the downstream, introducing the discharged mineral solution into a plate forming mold arranged at the outlet position of the high-temperature melting device to form a plate blank, and then moving the plate blank to the outlet position of a rotating disc type circular transfer mechanism along with the plate forming mold; the plate blank enters a subsequent conveying path to be subjected to multi-cabin segmented temperature control crystallization, the plate blank sequentially passes through temperature control cabins with three different temperature intervals to be subjected to segmented temperature control crystallization treatment, and finally a cast stone plate finished product is output. In short, the method has the advantages of being high in fly ash recycling degree, stable in continuous production, high in heat utilization efficiency and high in cast stone plate product engineering applicability.
