[0002] Aluminum ash is a dross generated in the production process of aluminum industry, which is a kind of toxic and harmful solid waste, but it still contains a large amount of metallic aluminum and aluminum compounds, and has high industrial recycling and reuse value. At present, the aluminum ash treatment methods in China are mainly divided into aluminum ash recycling, harmless treatment and resource recycling, one of the recycling methods is to use aluminum ash, limestone powder or quicklime to prepare calcium aluminate powder as water purifying agent. First, aluminum ash needs to be stored in a silo, then transported through a pipeline to mix aluminum ash and limestone powder, and then sent into a rotary kiln for calcination treatment. Finally, aluminum nitride and aluminum carbide in aluminum ash are converted into alumina, nitrogen and carbon dioxide, and no wastewater and waste residue are generated during production. However, aluminum ash is different from general powder, which has the characteristics of easy dusting, easy reaction with water and easy spontaneous combustion during discharging. In cold and humid areas, aluminum ash in the silo is easy to form a mass and accumulate at the discharge port during discharging, which leads to difficulty in conveying to the next process and low resource utilization rate. At the same time, a large amount of powder vertically falling can increase the pressure of the conveying pipe, which can easily cause overflow and a large amount of dust, thereby increasing the production cost of the enterprise.

Several exhaust ports and air inlets are provided on each vaporization plate 3 and communicate with the interior of the plate. The vaporization plates 3 are evenly distributed in a spiral stepped manner on the side wall of the cone hopper 2. They are connected to the air electric heater 11 and the fan 12 in sequence through air pipes, and the compressed and heated air is evenly delivered into the hopper, so that the aluminum ash inside is fluidized, preventing the aluminum ash from clumping and adhering to the side wall of the hopper, and ensuring smooth unloading of aluminum ash.
