Abstract

The invention discloses an iron removal device for an alumina material, comprising a housing, and a material inlet and a material outlet which are arranged on the housing, wherein the position of the material inlet is higher than the material outlet, a plurality of magnetic material rod are inserted into the inner cavity from the side surface of the housing to the iron removal device, and the magnetic material rods are all provided with handles. According to the invention, the device has the advantages of simple structure, low cost, and convenient usage, can effectively remove ferromagnetic impurities from the alumina material, and greatly reduces the iron content in the aluminium liquid in the production process of alumina by electrolysis.

Description

technical field [0001] The invention relates to the technical field of electrolytic aluminum production equipment, in particular to a device for removing ferromagnetic impurities in alumina pipeline transportation. Background technique [0002] The quality of aluminum is usually evaluated by the content of metal impurities in aluminum, and iron is one of the most important metal impurities. At present, it is difficult to control the iron content in molten aluminum. The iron impurities partly come from the alumina raw material in electrolytic production. When alumina is purified by flue gas, new iron impurities will be brought in, and some ferromagnetism will be brought in by friction with closed iron pipes. Impurities, how to solve this problem has become one of the topics studied by technicians. Contents of the invention [0003] In view of this, the object of the present invention is to provide a device for removing iron from alumina materials. The device has a simple s...
