Abstract

The invention discloses a device for preparing ceramsite by using waste incineration fly ash, which comprises an active material conveying type granulation unit and a drying and screening unit, a discharge port of the active material conveying type granulation unit is arranged corresponding to a feed port of the drying and screening unit, and the active material conveying type granulation unit comprises a conveying mechanism hinged to a rack. A conveying mechanism is arranged on the rack, the discharging end of the conveying mechanism extends into the granulating bowl, a driving mechanism is assembled between the conveying mechanism and the granulating bowl, a granulating cover is mounted at the opening end of the granulating bowl, a corner adjusting mechanism is mounted on the granulating cover, and a dip angle adjusting part is hinged between the conveying mechanism and the rack. According to the method, the quality of the prepared ceramsite can be effectively improved, when the incineration fly ash is used as a raw material, the situations that the fly ash diffuses and adheres to the surface of the ceramsite are avoided, the surrounding environment is prevented from being affected, the production process is simplified, the production difficulty is reduced, and meanwhile the production cost is reduced. The method is suitable for the technical field of preparation of the ceramsite from the waste incineration fly ash.
