A wet cycle electromagnetic separator

Abstract

The invention discloses a wet-type electromagnetic separator. The wet-type electromagnetic separator comprises a support seat, wherein an electromagnetic separation cylinder is arranged on the support seat through a rotating shaft. The wet-type electromagnetic separator is characterized in that the electromagnetic separation cylinder consists of an upper cone cylinder and a lower cone cylinder, wherein the bottom surfaces of the upper cone cylinder and the lower cone cylinder are connected, an upper water inlet / outlet and a lower water inlet / outlet are formed in the top ends of the upper cone cylinder and the lower cone cylinder, respectively, rotating shafts are respectively rotatably arranged in the upper cone cylinder and the lower cone cylinder, an upper group of electromagnets and a lower group of electromagnets are respectively fixedly arranged on the rotating shafts, an upper spray pipe and a lower spray pipe arranged outside the rotating shafts in a sleeved manner are arranged in the upper cone cylinder and the lower cone cylinder, and water spray holes are formed in the upper spray pipe and the lower spray pipe. According to the wet-type electromagnetic separator, by utilizing a specific dual-cone cycle structure, river sand or metal mortar can be circularly selected in two hollow cones when the cycle structure is driven to rotate to different positions by a driving device; the whole process is automatically controlled through circuits, so that the waste of manpower resources is reduced, the problems of complex separation method, long separation process and the like are solved, and the effectiveness of the electromagnetic separation is improved.

Description

technical field [0001] The invention relates to the field of wet circulating electromagnetic separation, in particular to a wet circulating electromagnetic separator for selecting iron sand from a mixed solution of river sand, ore pulp, non-metallic fine particles and iron impurities and removing iron impurities. Background technique [0002] Magnetic separation is the main beneficiation method for iron ore. After metal ore, especially iron ore, has been beneficiated, the grade has been improved and the impurity content has been reduced, which is beneficial to the smelting process. According to our country's practice, every 1% increase in iron concentrate grade can increase the blast furnace utilization factor by 2% to 3%, reduce coke consumption by 1.5%, and reduce limestone consumption by 2%. Many non-ferrous and rare metal minerals have different magnetic properties. When the final concentrate cannot be obtained by gravity separation and flotation, magnetic separation c...
