Abstract
The utility model relates to a high-purity iron flavor powder multi-stage desilicification and refinement device, which comprises a sorting tube, a composite alternating magnetic field and a composite sieve screen, wherein the sorting tube has the rectangular cross section. The problems of low sorting efficiency and low iron ore concentrate grade of the existing equipment because silicon mineral grains are mixed in the magnetite dressing process are solved. The magnetite is fed into the two-electrode alternating magnetic field which is divided into a plurality of layers from top to bottom, and the mineral grains repeatedly carry out multi-stage sorting through processes such as magnetization, loosening, reversing magnetization, secondary loosening and the like, so the dimension of magnetic floccules or magnetic chains formed by iron-containing high-grade mineral grains is increased, and low-grade mineral grains existing in a dispersed state are sorted through the use of the sieve screen and the alternate use of a flat plate and a composite sieve screen, and further, the multi-time fine selection effect is realized in one-step sorting operation, and the magnetite sorting precision and the concentrate grade can be obviously improved.
Description
Technical field
The utility model is applicable to the sorting equipment for purifying of impurity such as being mingled with silicon, titanium, fluorine, sulphur, phosphorus in the fine powder of magnetite, specifically relates to the multistage desiliconization purifying plant of the smart powder of a kind of high purity iron.
Background technology
The selected magnetic selection method that has adopted of magnetic iron ore divides two classes by magnetic field intensity at present: a class is conventional tubular magnetic separator, the magnetic field intensity height, and the iron recovery height, but impurity is mingled with seriously; Another kind of is picking equipment under the low magnetic field condition, magnetic agglomeration gravity separator, the magnetic separation post refiner of electromagnetism field type, wash mill as the permanent magnetic field type, and the magnetic field screening machine under the uniform magnetic field, preceding two kinds have formed the magnetic aggressiveness after by irregular magnetic flocculation the magnetic iron ore mineral being reunited, formed different differential settlements with the impurity particle that is the dispersity existence, utilize ascending water that impurity is gone out again, but to being difficult to sorting than coarse grain impurity, and water consumption is bigger; The back is a kind of to be in the uniform magnetic field that the two poles of the earth form relatively, magnetic iron ore is magnetized into chain magnetic aggressiveness, and the impurity that will fail to reunite along sieve wherein screens out, to iron mineral through reuniting after less than loose effect once again, also can exist to some extent to be mingled with, influence the raising of iron concentrate grade.
The utility model content
For overcoming the deficiency that prior art exists, the utility model provides the smart powder of a kind of high purity iron multistage desiliconization purifying plant.
Technical scheme:
The multistage desiliconization purifying plant of the smart powder of a kind of high purity iron, comprise that cross section is the separation tube of rectangle, composite alternating magnetic field and compound screen cloth, the both sides of described separation tube inwall from top to bottom successively fixed magnets form and to be at least forward and reverse secondary alternating magnetic field, described compound screen cloth tilts to be installed in the separation tube, the downside of this compound screen cloth is a compound slab, it is a web plate in magnetic field, the flat board of the section of having a common boundary in magnetic field, the online end of composite screen is provided with charging aperture, the lower end is provided with the smart powder discharging opening of iron, and the separation tube lower end is provided with discharging opening and automatic adjusting control valve door.
Described composite alternating magnetic field is a plurality of composite permanet magnet alternating magnetic fields that are combined to form with the little magnetic patch of magnetic, or the composite electromagnetic alternating magnetic field.
The magnetic block that adds that also is provided with in magnetic field with magnetic forms descending magnetic force.
Described compound screen cloth is a prismatic structures, comprises the baffle plate of compound slab, both sides screen cloth and opposite side.
The mounted angle of described compound screen cloth is 75 °～85 °.
Described magnetic field intensity is 10～1000 Gausses.
At least be fixed with a compound screen cloth in separation tube, according to ore dressing treating capacity needs, compound screen cloth can endlessly superpose.
The beneficial effects of the utility model: the sorting chamber internal magnetic field for both sides magnetic pole heteropole longitudinally alternately relatively, placement compound screen cloth wherein replaces magnetic field, corresponding region, line of demarcation at every group of magnetic pole and is flat board for more weak section, reverses in falling between next reverse pole region again after ore particle disperses in this interval and reunites again; The magnetic aggressiveness is along in screen cloth and the dull and stereotyped composite screen capable process off the net that replaces, the interval screen size of screen cloth is littler but bigger than selected material middling particle size than the magnetic aggressiveness on the sieve, and form same plane with dull and stereotyped interval, can allow the magnetic aggressiveness steadily descending on the net along composite screen, obtain concentrate on the net in composite screen, low-grade intergrowth and matter are assorted to be removed after separating from composite screen is off the net; But processes such as such separation operation repeated multiple times magnetization-loose-reverse magnetization-loose form multipass sort, and the smart powder of iron has been reached refining effect fully.
The magnetic block that adds that is provided with in resultant field with magnetic forms descending magnetic force, can improve the downstream rate of magnetic aggressiveness, thereby improves separation velocity.
The utility model also can be used for removing other objectionable impurities such as titanium, fluorine, sulphur, phosphorus.
