Abstract
The magnetic separation method and apparatus features that several permanent magnet blocks are contacted one by one to form one circle with the permanent magnet blocks in one semi-circle possessing clockwise magnetic force direction while those in the other semi-circle possessing counterclockwise magnetic force direction, and that one pipe of non-magnetically permeable material with inside soft magnetic material is set inside the permanent magnet circle. Ore powder to be iron eliminated is made to pass through the pipe, and under the magnetic force, iron material in the ore powder will be separated via attaching to the soft magnetic material. When the pipe is filled with the iron material, the pipe may be taken out to eliminate iron material for reuse. Compared with available technology, the present invention has the advantages of low cost, low power consumption, high magnetic field strength, easy maintenance, high iron eliminating efficiency, etc.
Description
Technical field:
The present invention relates to a kind of beneficiation method and equipment thereof.
Background technology:
It is existing that to separate weak magnetic impurity from nonmetallic ore (mainly be Fe
2O
3) technology have: 1, adopt chemical method, as with reducing agent with water-fast Fe
2O
3Be reduced to water-soluble divalent iron, use water rinse then, this method exists following shortcoming: A, cleaning frequency long, need very big place and rinsing not thorough, also have divalent iron in the material after the rinsing, divalent iron can become 3 valency iron in humid air, like this, time one is long, after divalent iron becomes 3 valency iron, can influence the colour developing of material and the colour developing of the goods made by this kind material; Can produce a large amount of waste water in B, the rinse cycle,, can cause very big harm environment if deal with improperly.2, adopt electromagnetic method, adopt electromagnetic method also to exist following shortcoming: A, energy consumption big, but magnetic field intensity generally is no more than 1 (T), therefore, influences de-ferrous effect; B, equipment investment are big, the maintenance requirement height.
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of small investment, magnetic field intensity height, safeguards magnetic selection method and equipment thereof easy, good iron removal effect.
Magnetic selection method of the present invention is to realize like this, one of several piece permanent magnet is close to plot surrounds circle, wherein, the magnetic force direction of permanent magnet blocks of half of circle is that the clockwise direction along half-turn distributes, the magnetic force direction of permanent magnet blocks of second half of circle is that the counter clockwise direction along another half-turn distributes, then will be at the pipe made by non-magnet_conductible material of middle setting of circle, in pipe, be provided with soft magnetic materials, the breeze flowing pipe of deironing will be needed, like this, under the effect of magnetic force, iron in the breeze will stick on the interior soft magnetic materials of pipe, thereby the iron in the breeze is cleared out, when soft magnetic materials sticks iron in waiting to manage, take-off pipe just can come into operation the removing of the iron on the soft magnetic materials in the pipe again.Owing to there is side by side and the intensive magnetic line of force that direction is identical of two bundles to pass through in the circle, the magnetic force that just constitutes all permanent magnet blocks of circle all concentrates in the circle, like this, has very strong magnetic force in the circle, its magnetic force can be up to 1.5 (T), flowing molten iron in the breeze under the effect of powerful magnetic force, will be adsorbed on the interior soft magnetic materials of pipe when being arranged in circle pipe soft magnetic materials.
Here, in order to increase adsorption area and magnetic field gradient, promote the ability of absorption iron, the soft magnetic materials in pipe is the steel wool of being made by the soft magnetic bodies silk.Like this, breeze is under the drive of fluid (as water), and when passing steel wool, the iron in the breeze (comprising the weak magnetism compound) will be attracted on the steel wool.Because steel wool is made with the soft magnetic bodies silk, like this, every soft magnetic bodies silk just forms a magnetic field gradient, and countless soft magnetic bodies silks is arranged in the steel wool, therefore, form countless magnetic field gradients in the steel wool, and countless soft magnetic bodies silks formed very big adsorption area, made the iron-based in the breeze of flowing pipe originally be eliminated out.
Magnetic plant of the present invention is to realize like this, mainly constitute by be close to circle that plot surrounds and the non-magnetic pipe that is arranged in circle by one of several piece permanent magnet, be provided with soft magnetic materials in the pipe, the magnetic force direction of permanent magnet blocks of half of circle is that the clockwise direction along half-turn distributes, and the magnetic force direction of the permanent magnet blocks of second half of circle is that the counter clockwise direction along another half-turn distributes.Soft magnetic bodies in pipe is the steel wool of being made by the soft magnetic bodies silk.
Here, in order to prevent running off of magnetic force, be provided with the armour spare of making by permeability magnetic material at the lateral surface that encloses toward circle is outer.Owing to the existence of the armour spare that has permeability magnetic material to make, the magnetic line of force of each permanent magnet in the outside only concentrates on the armour spare and along the magnetic line of force and acts on the middle part of circle, and can not be dissipated on the outer space.
Operation is provided with cleaning device and charging gear above pipe for convenience, is provided with the material guide groove that swings up and down below pipe, and a wherein outlet of material guide groove is provided with blow tank, and another discharging opening is provided with row's metal trough.During work, with the up perk of material guide groove, make its guiding blow tank, start charging gear, breeze is under the drive of fluid (as water), and flowing through is positioned at the pipe of circle, and the iron in the breeze is attracted on the interior steel wool of pipe, breeze after the deironing drops into blow tank along the material guide groove, after steel wool in waiting to manage has been filled iron, pipe is moved down, away from the magneticaction scope of circle, simultaneously, the material guide groove bottom makes its guiding row metal trough, starts cleaning device, iron on the steel wool that pipe is interior is rinsed and drops on the material guide groove, and falls on row's metal trough along the material guide groove.
Here, make for convenience, being shaped as of permanent magnet blocks is fan-shaped, and the circle that is surrounded is a circle, and the hole in the circle is a circular hole.
Make, use for both convenient, can strengthen magnetic force again simultaneously, circle is to be made of two or more magnetospheres that are made of the individual layer permanent magnet blocks, and each magnetic force direction of enclosing axial corresponding permanent magnet blocks is identical.
The present invention compared with the prior art, have small investment, energy-conservation, magnetic field intensity is high, maintenance is easy, the advantage of good iron removal effect.
