Embodiment Construction

[0028] The invention is described in detail below according to specific embodiments:

[0029] The composite wave demagnetizer is composed of charging circuit 2, oscillation circuit 3 and microcomputer control system 1. Microcomputer control system 1 uses capacitors and demagnetization coils to form and connect vibration circuits to generate damped oscillations. The first and second damped oscillation waves with different frequencies and amplitudes are generated through the intelligent control system, and synthesized to form composite waves. The composite wave of reciprocating oscillation produces an alternating magnetic field with small axial gradient and large field strength in the coil, so that the ore pulp flows through the coil to obtain demagnetization.

[0030] The technical scheme of the present invention adopts the alternate working mode of double demagnetization coils, and the non-metallic pulp pipe 6 adopts non-metallic materials, such as high molecular weight polyet...

Abstract

The invention relates to a compound wave demagnetizer which comprises a charging circuit, an oscillation circuit and a microcomputer control system. The microcomputer control system is formed by using a capacitor and a demagnetizing coil and is connected with the oscillation circuit to produce damped oscillations, a first damped oscillation wave and a second damped oscillation with different frequencies and amplitudes are produced through the intelligent control system, and the two damped oscillation waves are synthesized to form a compound wave. The compound wave oscillating back and forth enables an alternating magnetic field with smaller axial gradient and larger field intensity to be produced in the coil, so that ore pulp is demagnetized after flowing across the coil. The alternate operating mode of dual demagnetizing coils is adopted, the ore pulp pipe is made of a nonmetal material, such as macromolecule polyethylene; the demagnetizing coils are divided into a group A and a group B. The coils have full specifications and are divided into a pipe type and a belt pipe. The compound wave demagnetizer has the advantages of high integration level, good interchangeability, simple operation, dual coil alternate operation, good demagnetizing effect and the like; and the input current is not greater than 3A, the demagnetizing field intensity is 80-160 kA / m, and the quality and the yield of iron powder in a metal mine can be effectively improved.

Description

technical field [0001] The invention relates to a demagnetizer, in particular to a composite wave demagnetizer, belonging to the technical field of mineral demagnetization. technical background [0002] As a ferrimagnetic mineral, magnetite has a large coercive force and remanence. In the existing magnetic separation equipment, the strong magnetic field causes the magnetite to agglomerate strongly, resulting in a decrease in the separation accuracy and deterioration of the separation process. indicators, and even affect the subsequent concentration, dehydration and filtration operations. [0003] Magnetite (Fe3O4) is a ferrimagnetic material. Due to different sources, the magnetic properties of magnetite are different. These differences are caused by many factors. Among them, the magnetic differences of magnetite are formed by the different mineralization conditions and artificial processing technology conditions. The magnitude of the remanence coercive force in the magnet...
