Description

Technical field

[0001] The invention relates to the technical field of magnetic separation equipment for separating solids from solid materials, in particular to an electromagnetic iron remover for removing impurities in block or powder non-magnetic materials. Background technique

[0002] Electromagnetic iron remover is especially suitable for removing ferromagnetic substances from bulk nonmagnetic materials, and has been widely used in cement, thermal power generation, metallurgy, mining, building materials, coal and other industries. According to different cooling methods, electromagnetic separators can generally be divided into oil-immersed electromagnetic separators, dry electromagnetic separators and air-cooled electromagnetic separators. The cooling medium of the oil-immersed electromagnetic separator is transformer oil (or high-temperature-resistant oil), which uses single-phase medium convection heat exchange, which has the advantage of high electrical strength, but...

Examples

Embodiment 1

[0017] Embodiment 1: An evaporative cooling type electromagnetic iron remover, including a housing 1 and an iron core 2 arranged in the housing 1, a coil 3 is wound around the outer periphery of the iron core, and the coil lead wire 7 is drawn from the upper part of the housing 1, and the housing 1 An evaporative cooling medium 4 is installed in the inner cavity, and the evaporative cooling medium 4 adopts one of the evaporative cooling medium Fla, the evaporative cooling medium 4310 or the evaporative cooling medium 3000, and the coil 3 is completely immersed in the evaporative cooling medium. A condenser 5 is installed on the top of the housing 1 through a bracket 6, and one end of the condenser 5 is connected with a gas collecting pipe 8, and the lower end of the gas collecting pipe 8 communicates with the upper part of the housing 1, and the lower part of the condenser 5 is connected with a liquid return pipe 9, which returns The lower end of the liquid pipe 9 is connected ...

Embodiment 2

[0019] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a part of the coil 3 is immersed in the evaporative cooling medium, and the coil height of the immersed part is greater than 1 / 3 of the total coil height. The condenser 5 is water-cooled, and it has a cylindrical shell. The shell is equipped with a plurality of condenser pipes 22 through which secondary cooling water is passed inside. The inner end of the condenser pipe 22 is connected to an inner water box 23 installed in the shell. Connection, the outer end of the condensation pipe 22 is connected with the outer water box 18 installed on the outside of the shell, and there is a transverse partition 19 inside the outer water box 18, which divides the outer water box 18 into a lower water inlet chamber and an upper water outlet chamber, A cooling water inlet pipe 20 is connected to the water inlet chamber, and a cooling water outlet pipe 21 is connected to the water outlet chamber. A pressure ...

Embodiment 3

[0021] Embodiment 3: The difference between this embodiment and the above embodiment is that the cooling medium 4 is a mixture of evaporative cooling medium and transformer oil, the weight ratio of evaporative cooling medium and transformer oil is 1:2, and the coil 3 is completely immersed in the cooling medium. medium.

[0022] Due to the high current density of the electromagnetic separator of the present invention, the required coils are reduced, and the corresponding volume and weight are also reduced, and the boiling heat transfer coefficient of the heating surface is several times higher than that of the single-phase fluid convective heat transfer. Dozens of times, the cooling effect is good, and in the event of a failure, because the evaporative cooling medium is non-flammable, it will ensure that the electromagnetic separator will not fire. Therefore, the evaporative cooling electromagnetic iron remover has a high degree of safety and considerable economic benefits.
