Description
Technical field:
The present invention relates to electromagnetic dressing fields, refer specifically to high magnetization high gradient component power supply.
Technical background:
Traditional electromagnetism high gradient magnetic separator, magnetizing field and high-gradient magnetic field are powered using same pure DC power supply, high
The ferromagnetic mediums such as gradient magnetic steel wool generate, and due to the magnetic saturation of ferromagnetic medium, make high magnetizing field and high-gradient magnetic field
As conflicting problem, after magnetizing field is more than 10,000 Gausses, magnetic field is increased, magnetic field gradient reduces instead, works as magnetic
After magnetizing field reaches 20,000 Gausses, magnetic field average gradient is almost nil, and the elimination factor of magnetisable material is caused to decline instead, and by
The magnetizable material of choosing, but requiring magnetizing field, the higher the better.Therefore, for magnetic separator provide it is a kind of not only there is high magnetizing field but also
Component power supply with high-gradient magnetic field, solves the basic contradiction of high magnetizing field and high-gradient magnetic field, for improving magnetic separator
Magnetic separation performance, reduce operating cost and save electric energy, all have breakthrough technical meaning.
Summary of the invention:
The purpose of the present invention is that high magnetizing field can be generated but also generate the high magnetic of high-gradient magnetic field by providing one kind
Change high gradient component power supply, it is made of component pulse controller 1, controlled rectifier 2, as shown in Figure 1.Component pulse controller
1, it is made of electronic synchronizer impulse circuit, can produce one or two group of simultaneous phase-shifting pulse signal, controlled rectifier 2 is controlled
System, controlled rectifier 2 are made of two or one groups of semiconductor rectifier circuits, and controlled rectifier exports the voltage of two components of A, B, A
Component voltage is of short duration high level, and B component voltage is to continue low value.By the magnetic separator of component power supply power supply, produced in magnetizing coil
Raw A B component excitation current.A component excitation current generates of short duration high magnetizing field, carries out to weak magnetic substance force-magnetized；B points
It measures excitation current and generates and continue high-gradient magnetic field, lasting strength is carried out to the magnetic substance that is magnetized and inhales choosing；A B component excitation current
It is adjustable, it is generated in magnetic separation area and adds adjustable electric and magnetic oscillation, to promote the efficient magnetic separation of slurry, accomplish that magnetic separator can be transported efficiently
Row and energy conservation, theory save electric energy up to 90% or more.
Detailed description of the invention:
Fig. 1: magnetize high gradient component power principle schematic diagram for height.
Specific embodiment:
Implementation of the invention is with electronics clock circuit, composition one-component impulse controller, generation A B
Two groups of simultaneous phase-shifting pulse signal outputs, control silicon controlled rectifier (SCR) generate A B component voltage, supply magnetic separator excitation line Quan,
Generate A B component excitation current.A component excitation current generates of short duration high magnetizing field, carries out to weak magnetic substance force-magnetized；B
Component excitation current, which generates, continues high-gradient magnetic field, carries out lasting high gradient strength suction to the magnetic substance that is magnetized and selects；A B component swashs
Magnetic current adjustment generates in magnetic separation area and adds adjustable electric and magnetic oscillation, to promote the efficient magnetic separation of slurry.Using this power supply power supply
Magnetic separator, guaranteeing magnetic separation quality and in the case where efficiency, save electric energy up to 80% or more through preliminary test.
