Abstract

The invention discloses a porous medium auxiliary molten salt electrolysis metal refining device, and belongs to the field of molten salt electrolysis metal refining devices. The device comprises a shell, an outer barrel and an inner barrel, wherein a through hole is formed in a barrel body of the inner barrel; an electrode is fixed on the inner wall of the inner barrel; the inner barrel is positioned in the outer barrel; a heating device is arranged on the outer side of the outer barrel; and the outer barrel is positioned in the shell. Multiple cylindrical projections are arranged on the inner wall of the through hole; lattices are arranged on the end surfaces of two ends of the through hole; and the radius of the end surfaces of two ends of the through hole is smaller than the radius of the cross section of the middle part of the through hole. The device aims to overcome the defect of incapability of smoothly performing electrolysis refining due to incapability of fixing electrolytes between crude metal and refined metal with close densities in the molten salt electrolysis refining of metal melts in the prior art, realizes fixation of the electrolytes between the crude metal and the refined metal with close densities, widens the application range of a molten salt electrolysis refining technology, and improves the metal refining effect.

Description

technical field [0001] The invention relates to a molten salt electrolytic refining metal device, in particular to a porous medium assisted molten salt electrolytic refining metal device. Background technique [0002] When the liquid metal melt is refined by molten salt electrolysis, because the density of the crude metal and the refined metal are close, it is difficult for the molten electrolyte to exist stably between the crude metal and the refined metal melt. Only a diaphragm that allows specific ion migration or a Weighting agents increase the density of crude metal melts, such as pure copper weighting agents used in three-layer electrolytic refining aluminum technology. [0003] According to the patent search, the relevant technical schemes of using diaphragms for molten salt electrolytic refining of metals have been disclosed in the prior art, such as the patent publication number CN203700538U, the publication date is July 9, 2014, and the name of the invention is: a ...
