Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stirring mixing equipment, in particular to a mixing equipment for preparing household garbage incineration fly ash polymer. BACKGROUND

[0002] After the household garbage is treated by incineration, fly ash is left, and solidification is one of the commonly used methods for treating fly ash. The method forms stable solid substances by mixing fly ash with a solidifying agent, thereby reducing the leaching toxicity thereof. Commonly used solidifying agents include cement, kaolin, asphalt, molten glass, etc. The fly ash is mixed with the solidifying agent, an appropriate amount of water is added, and then stirring is performed, and then the slurry is poured out, and the cement solidified body is formed after waiting. The volume of the solidified fly ash can be reduced to 2-10% of the original garbage, and has excellent leaching resistance, dry and wet resistance, permeability resistance, and freezing resistance, and also has sufficient mechanical strength. The solidified fly ash can be used in the fields of soil conditioner, building materials (such as cement, concrete, ceramics, etc.), geotechnical engineering materials (such as construction of roadbed and dam, etc.), and adsorption materials (such as zeolite), etc. However, it should be noted that the solidification method cannot completely remove heavy metals and organic pollutants in the fly ash, but only fixes them in the solidified body to prevent leaching and diffusion.

[0003] Before the fly ash is fixed, it needs to be fully mixed and stirred with the fixing agent, so that the fly ash and the solidifying agent are fully and uniformly mixed. The existing fly ash solidification special stirring device mainly consists of a motor, a transmission device, a stirring body, and a hopper. However, during stirring, single-shaft stirring is usually used, which can easily cause the internal mixture to form a fixed rotating speed during stirring, and the upper and lower materials are not easy to mix, resulting in uneven mixing and long stirring time, and there is a certain limitation.
