Embodiment approach

[0039] As an embodiment of the present invention, a number of No. 1 grooves are provided on the grinding and smashing disk 22, and the No. 1 grooves are circumferentially distributed on the grinding and smashing disk 22, and a crushing rod 221 is provided on the No. 1 groove; the crushing rod 221 It is fixedly connected to the No. 1 groove by a spring, and the crushing rod 221 is threadedly connected to the inner wall of the No. 1 groove. The gas generated during the expansion and contraction of the No. 1 double-head cylinder 41 and the No. 2 double-head cylinder 42 acts on the crushing rod 221 to make the crushing The rod 221 is unscrewed to crush the aluminum slag. In the present invention, by setting the breaking rod 221, on the one hand, the gas produced by the No. 1 double-head cylinder 41 and the No. 2 double-head cylinder 42 is utilized, thereby improving the utilization rate of resources; The gas produced by 41 and No. 2 double-head cylinder 42 acts on the crushing rod...

Abstract

The invention belongs to the technical field of aluminum slag recovery, and particularly relates to a high-efficiency aluminum slag recovery method. According to the method, on one hand, sodium chloride, potassium chloride, sodium fluoroaluminate and calcium fluoride form a separating agent, and the separating agent and an aluminum slag are stirred and mixed according to the proportion of 5:1; ifless separating agent is used, the aluminum slag is wetted incompletely, the produced oxycompound is high, and the viscosity is high; if excessive separating agent is used, the aluminum slag cannot berecovered; and through setting the proportion to be 5:1, the occurrence of the phenomenon that the separation and the recovery of the aluminum slag are influenced by the separating agent is avoided,the recovery rate of aluminum is improved to 96 percent from 70 percent, and the aluminum recovery efficiency of the aluminum slag is greatly improved. On the other hand, through the matching of a heating block and a pump, the temperature of a tank is kept to range from 650 to 680 DEG C, so that the separating agent sufficiently produces reaction on the aluminum slag; and meanwhile, hot air extracted by a pump is used for drying the mixed aluminum slag, and the mixed aluminum slag is prevented from adhering, so that the aluminum slag separating and recovering effect is improved.

Description

technical field [0001] The invention belongs to the technical field of recycling aluminum slag, in particular to an efficient recycling method for aluminum slag. Background technique [0002] Various by-products are produced during the aluminum smelting and forming process. As the main by-product of the aluminum industry, aluminum ash is produced in all aluminum melting processes, and the aluminum content in it accounts for about 1-12% of the total loss in the process of aluminum production and use. In the past, people regarded aluminum slag as waste and dumped it, which not only caused a waste of aluminum resources but also brought environmental problems. Therefore, finding an economical and effective method to utilize and control aluminum slag will not only improve the economic benefits of the aluminum industry, but also have an important impact on the sustainable development of the economy and society while realizing the effective recycling of resources. [0003] There ...
