An Exciting Coil Structure of a Vertical Ring High Gradient Magnetic Separator

Abstract

The invention discloses a vertical ring high-gradient magnetic separator magnet exciting coil structure. The magnet exciting coil structure comprises a multiple layers and turns of magnet exciting coils and a magnet exciting coil sealing cover. The magnet exciting coil structure is characterized in that the magnet exciting coils are formed through winding of hollow red copper guide wires with theinner cross section being round, the outer cross section being regular hexagonal and coated with an insulation layer, the adjacent two turns of hollow red copper guide wires are in contact face to face, the hollow red copper guide wires between the adjacent two layers are in contact edge to edge, the two ends of the magnet exciting coil sealing cover are provided with an external cooling oil filling port and an external cooling oil outlet, the magnet exciting coil sealing cover is further provided with an internal cooling oil filling port and an internal cooling oil outlet which are communicated with the internal round channel of the hollow red copper guide wire, and the oil outlets and the oil filling ports are communicated with an oil cooling device. The vertical ring high-gradient magnetic separator magnet exciting coil structure has the advantages that 1, composite cooling of the inner and outer surfaces of the hollow red copper guide wire is achieved, the background magnetic fieldof the vertical ring magnetic separator can be enlarged by increasing the sectional area of the magnet exciting guide wire under the premise that the cooling effect is ensured, the size of the magnetexciting coil is reduced, and the background magnetic field is stabilized; 2, consumption of clean water is reduced; and 3, the scaling faults of the magnet exciting coil are decreased.

Description

technical field [0001] The invention belongs to the technical field of vertical ring high gradient magnetic separator in magnetic separation equipment, and in particular relates to an excitation coil structure of vertical ring high gradient magnetic separator. Background technique [0002] The vertical ring high-gradient magnetic separator is one of the key equipments for the separation of weak magnetic minerals and the removal and purification of non-metallic ores. magnetic field, and then use the magnetization medium on the swivel that passes through this position to be magnetized in the background magnetic field to generate a higher induction magnetic field, a high gradient magnetic field is formed on the surface of the magnetization medium, and the weakly magnetic minerals in the pulp are adsorbed on the magnetization medium , with the rotation of the swivel ring, it is brought into the upper non-magnetic field area of ​​the vertical ring high gradient magnetic separator...

Problems solved by technology

[0005] Cooling water has a large specific heat capacity and high cooling efficiency, but it has high requirements on water quality. After long-term use, the inner wall of the coil is prone to fouling and clogging. In addition, the water resources after cooling are naturally lost, resulting in waste of resources.

Although the coolant can achieve a closed cycle, due to the small specific heat capacity, the cooling efficiency is low
