Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of aluminum ash recycling, in particular to an aluminum metal solvent production system. BACKGROUND

[0002] The aluminum metal solvent, namely, the slagging agent and the refining agent, is a chemical preparation for adding and purifying impurities in the process of aluminum liquid casting and alloy casting. It can change the surface and interfacial tension between the metal melt and the slag body, reduce the binding force of the melt and the slag body, effectively separate the metal and the slag, and improve the utilization rate of the metal. After the slagging agent and the refining agent are added to the metal melt, a large number of bubbles can be emitted to have a certain mixing effect on the melt, and the slag entrained and adsorbed in the metal liquid can be fully stirred and dragged to the surface of the metal liquid, which is beneficial to completely removing the slag and ensuring the cleanliness of the melt. The slagging agent and the refining agent have adsorption and melting capacity for the slag body, can fully purify the metal melt, and reduce the pollution of the slag to the metal. Currently, the slagging agent and the refining agent are mainly prepared by processing different finished salts, and the cost is relatively high. The sintered dust collection material generated in the sintering process of aluminum ash by fire method still contains useful components such as sodium fluoride, sodium chloride and potassium chloride. The components are similar to the components of the high-value product slagging agent required by electrolytic aluminum and aluminum alloy. The slagging agent can be prepared by using the sintered dust collection material of aluminum ash by fire sintering, so as to achieve the purpose of effective disposal and utilization of hazardous waste and realize resource utilization and recycling.
