Composite-magnetic-pole electromagnetic iron remover

Abstract

The invention discloses a composite-magnetic-pole electromagnetic iron remover which is composed of a junction box (1), a lifting lug (2) and a magnetic system (3), wherein the magnetic system (3) is formed by sequentially connecting coils (6), an iron core (8), a cylinder (7), a cooling fin (9), a big yoke plate (4), a small yoke plate (5) and a bottom plate (10). The strength of a magnetic field is enhanced, the range of the magnetic field is widened, and therefore, the adsorption capacity is greatly improved. The composite-magnetic-pole electromagnetic iron remover can successfully absorb relatively large and relatively long ferromagnetic impurities so as to achieve the purpose that the ferromagnetic impurities in materials in a variety of conditions can be removed. The two sets of coils of the composite-magnetic-pole electromagnetic iron remover can work at the same time and can also independently work. On one hand, when a metal detector sends a signal for presenting that the relatively large or relatively long ferromagnetic impurities exist, the two coils are adopted for delivery of current at the same time; the strength of the magnetic field is enhanced, the range of the magnetic field is widened, the adsorption capacity is improved, and the relatively large or relatively long ferromagnetic impurities can be successfully absorbed; the smoothness of iron removal is realized; on the other hand, in general, a signal coil is adopted for the delivery of current, and therefore, energy is saved.

Description

Technical field [0001] The invention relates to an iron separator, in particular to a composite magnetic pole electromagnetic separator. Background technique [0002] The iron separators on the market today are divided into electromagnetic separators and permanent magnet separators according to the excitation method. Electromagnetic separators have low manufacturing cost, good performance, simple structure, convenient operation, stable and reliable operation, and wide application. However, the electromagnetic separator has a major drawback, that is, when there are large ferromagnetic debris in the material, it is difficult to adsorb due to the limitation of the magnetic field strength and range, which causes the electromagnetic separator to not work smoothly and normally. Especially when there are long ferromagnetic debris, both ends of the long piece cannot be sucked up at the same time. While one end is sucked up, the other end is supported on the material conveying belt, which...

Problems solved by technology

However, the electromagnetic iron remover has a big disadvantage, that is, when there are large ferromagnetic impurities in the material, it is difficult to absorb due to the limitation of the magnetic field strength and range, so that the electromagnetic iron remover cannot work smoothly.

Especially when there are long ferromagnetic sundries, both ends of the long piece cannot be sucked up at the same time. While one end is being sucked up, the other end is supported on the belt conveying the material, which is very easy to scratch the conveyor belt. Phenomenon

Cause damage to the conveyor belt and affect normal production, and even lead to serious consequences of production stoppage

Its scope of use is greatly limited and cannot meet the needs of on-site operations
