Dry type strong magnetic screening device used for steel and iron manufacture

Abstract

The invention belongs to the field of steel and iron manufacture, and particularly relates to a dry type strong magnetic screening device used for steel and iron manufacture. The technical problem tobe solved is to provide the dry type strong magnetic screening device used for steel and iron manufacture, wherein the dry type strong magnetic screening device is uniform in heat born by ore and highin ore screening work efficiency. The dry type strong magnetic screening device used for steel and iron manufacture comprises a fixed frame, a first collection frame, a first discharge hopper, secondcollection frames, guide inclined plates, scrapers, electromagnetic rollers, a second discharge hopper, an installation box, a spiral blade and the like. A treatment barrel is embedded in the top ofthe installation box. A bearing pedestal is embedded in the top of the treatment barrel. A hollow rotating rod is connected with the bearing pedestal in a pivoted manner. The spiral blade is fixedly connected to the outer surface of the hollow rotating rod and is located in the treatment barrel. A first gear is fixedly connected to the outer surface of the hollow rotating rod. By means of the drytype strong magnetic screening device, the effects that the ore is uniformly heated and the ore screening work efficiency is high are achieved.

Description

technical field [0001] The invention belongs to the field of iron and steel manufacturing, in particular to a dry strong magnetic screening device for iron and steel manufacturing. Background technique [0002] Before steel manufacturing, ore crushing and screening will be carried out, and ores of different properties will be distinguished by dry strong magnetic screening machine. [0003] Chinese patent CN207025559U aims at the existing dry-type strong magnetic screening machine for iron and steel manufacturing on the market with complex structure and single function, no heater is provided, the ore cannot be heated, no induced fan is provided, and the vibration generated after vibration cannot be performed. The dust is collected, there is no filter cartridge, the collected dust cannot be filtered and then discharged, the vibration plate is not set at an angle of 45 degrees to the horizontal direction, and the feeding speed cannot be increased. This kind of dry-type strong ...
