Summary of the invention
The purpose of this utility model is exactly at the above-mentioned problems in the prior art, provides a kind of and sorts that precision height, equipment operation are reliable, the permanent magnet high gradient magnetic separator of the reasonable energy-conserving and environment-protective of Distribution of Magnetic Field, and it can sub-elect the particulate weak magnetic mineral effectively.
For achieving the above object, the utility model permanent magnet high gradient magnetic separator has adopted following technical scheme:
The utility model permanent magnet high gradient magnetic separator comprises vertical configuration and the separation ring of magnetic matrix is housed and driving mechanism, enclosed permanent magnetic system, mine feeding bucket, non magnetic ore ore discharge case, concentrate bucket, frame, the concentrate bucket is arranged in the separation ring, and the concentrate flushing line is positioned at the top of separation ring and corresponding with the concentrate bucket that is located at separation ring.Its characteristic: described permanent magnetic system is positioned at below the separation ring, the medium box of magnetic system encirclement separation ring forms closed magnetic circuit up and down, magnetic line of force direction is vertical with the axis direction of separation ring, and following magnetic is that inside is provided with the ore pulp passage, and last magnetic is that inside is provided with the flushing water water route; It also contains pulse mechanism, and described pulse mechanism links to each other with non magnetic ore ore discharge case.
Divide the internal field, constituency strong size for adjusting easily,, the adjustment jack is housed on last lower yoke to adapt to the requirement of different minerals sorting.
The ore pulp import is passed from last magnetic is, ore pulp enters in the separation ring magnetizing mediums case, can not cause that the ore pulp short circuit influences separating effect.
Compared with prior art, the utility model has been taken into account the highfield electromagnetic pulsating high gradient magnetic separator in design, and iron wheel type permanent magnet high gradient magnetic separator advantage separately makes it to have had following good effect:
1, energy savings, the exciting power of common high field intensity electromagnetic separator accounts for the 80-95% of whole magnetic separator power, adopt permanent magnetic system after, this part power consumption can complete exemption, thereby energy-conservation more than 80%.
2, the continuous high gradient magnetic separator combines with pulse mechanism is ingenious, realizes the pulsed high-gradient magnetic separation, except that can obtaining the higher rate of recovery, can improve the grade of magnetic product especially significantly; Under the effect of pulse mechanism, the retentate that rests in the magnetizing mediums heap is constantly impacted in the vibration of ore pulp, and the blockage problem of magnetizing mediums is eliminated; Avoided the obstruction of the mine tailing exit passageway in the magnetic system simultaneously.
3, magnetic field intensity of the present utility model, pulse stroke, mineral slurry flux and change rotating speed can be regulated within the specific limits, help selecting optimum sorting condition according to selected feedstock property.
4, machine heavy and light, take up an area of few, adopt permanent magnetic system to replace electromagnetism magnetic system after, magnetic is that weight reduces significantly, and volume also reduces thereupon, thereby has saved manufacturing cost, has reduced producing cost, has reduced the occupation of land space.
Description of drawings
In order to further describe the utility model,, the utility model permanent magnet high gradient magnetic separator is done more detailed description again below in conjunction with drawings and Examples:
Fig. 1 is the utility model permanent magnet high gradient magnetic separator structural representation.
Fig. 2 is that the utility model permanent magnet high gradient magnetic separator magnetic architecture master cuts open structural representation.
Fig. 3 is that structural representation is cutd open on the utility model permanent magnet high gradient magnetic separator magnetic architecture left side.
Fig. 4 is the utility model permanent magnet high gradient magnetic separator separation ring structural representation.
