The research of three-dimensional magnetic field of the hybrid magnetic system in the ANSYS Maxwell program

摘要

The results of the research of magnetic field of hybrid magnetic system consisting of a Π-shaped electromagnetic iron separator and knife-like form concentrators. These magnetic systems are used in the food industry, agricultural processing enterprises, concentrating mills, thermal power plants, factories of building materials industry, coking plants for extraction of ferromagnetic particles from the material to be cleaned; in steel mills for slag cleaning. To enhance the concentration of the magnetic field of the Π-shaped electromagnetic iron separator there are used nozzles of a special kind. Purpose: to examine imitating models of two constructions of electro technical devices: Π-shaped electromagnetic iron separator without magnetic enhancers and the hybrid magnetic system (iron separator and concentrators). Objectives: to develop separators constructions, their physical, mathematical and simulating models; get a picture of the magnetic field, strength characteristics due to numerical experiments. Research methods: numerical calculations were performed using the finite element method in ANSYS Maxwell program. Results: it is shown that the hybrid model of the iron separator allows strengthening magnetic field at a distance from the magnetic circuit through the use of special concentrating nozzles of special shape.
