The invention relates to the field of mineral processing and recycling of secondary raw materials and can be used for separation by density mixtures of different non-magnetic materials.

Known magnetohydrostatics separator (USSR Author's certificate No. 1041154, IPC B03C 1/30, 1983), including the electromagnetic system with pole pieces hyperbolic profile, the camera with the magnetic fluid is placed in the gap between pole pieces, feeder and receiver separation products. Working surfaces of the pole pieces from the feeder are arranged in a horizontal plane at an angle to each other, the disclosure of which is performed in the direction from the input end to the work surface, which separates the source material into two fractions - heavy and light.

The disadvantages of this separator are low selectivity, leading to the separation of all original material only into two groups of heavy and light, and, as a consequence, the low efficiency of separation, if necessary, separation of the source material for several different density fractions.

The prototype of the present invention is ferrochelatase separator (USSR Author's certificate No. 1136840. IPC B03C 1/30, 1985), which includes a magnetic system with pole is ecorecycle, having a hyperbolic profile both in vertical and in horizontal planes, the camera with the magnetic fluid located in the interpolar gap, loading and unloading devices.

The disadvantages of this separator are the complexity of manufacturing poles with hyperbolic profile both in vertical and in horizontal planes, and low selectivity, leading to the separation of all original material only into two groups of heavy and light, and, as a consequence, the low efficiency of separation, if necessary, separation of the source material for several different density fractions.

The technical result is to increase efficiency and productivity magnetohydrostatic separator.

This technical result is achieved by the fact that magnetohydrostatics separator comprising a magnetic system with pole pieces having a hyperbolic profile in the vertical plane, the camera with the magnetic fluid located in the interpolar gap, loading and unloading device according to the invention provided with a device for regulating the angle of inclination of the magnetic system to the horizon in the range from 0 to 45 degrees, two or more pairs of pole pieces form the same number of lots interpolar what about the gap, moreover, the effective density of magnetic fluid adjacent parcel satisfies the condition ρkk+1where ρ is the effective density of the magnetic fluid, k is the sequence number of the segment, each pair of pole pieces provided with a control magnetic field. In the vertical clipping plane profile of the working surface of the pole tip has a hyperbolic shape, or trapezoidal shape, or a polygonal shape. Edge working the pole tips rounded. Regulators magnetic field strength made in the form of ferromagnetic plates arranged with the possibility of vertical movement between each pole tip and the core of the magnetic system, and a magnetic shunts installed with possibility of vertical motion over each pair of pole pieces.

The design of the proposed magnetohydrostatic separator illustrated by the drawings shown in figures 1-4:

Figure 1. Magnetohydrostatics separator (front view and top view).

Figure 2. Magnetohydrostatics separator (left side view).

Figure 3. The profile shape of the surface of the pole tip (a) - hyperbolic profile; (b) trapezoidal profile; and (C) and (d) a polygonal profile.

Figure 4. The location of the magnetic shunt on pin nakone the parties.

Electromagnetic separator system (1, 2) consists of a ferromagnetic core 1 with the magnetizing winding 2. Along the length of the core in its upper parts are pairwise symmetric and parallel pole pieces 3, forming a corresponding number of pairs number of lots interpolar gap, extending to the outlet end of the separator (in the drawings shows an example of a separator with four pairs of pole pieces). In the interpolar gap posted by camera 4 of non-magnetic material. In the chamber 4 is a magnetic fluid 5, which is maintained by the magnetic field generated by the coil 2 when the flow through it of an electric current I. the Separator contains the boot device 6 and the discharge device with the container 7 for separation products, the number of containers corresponds to the number of lots interpolar gap and the number of pairs of pole pieces 3. Between the core 1 and each pole tip posted by ferromagnetic plate 8, when moved in the vertical direction between the core 1 and the pole tip is formed an air gap Δ1. Above each pair of pole pieces mounted magnetic shunts 9 (figure 4)made in the form of plates made of ferromagnetic material. The air gap Δ2between the magnetic shunt pairs 9 and the second pole pieces 3 is adjusted by moving the shunt 9. The separator is provided with a device for regulating the angle of inclination α of the magnetic system to the horizon in the range from 0 to 45 degrees (not shown).

In the vertical clipping plane interpolar gap, formed by the pairs of pole pieces, extends up. The geometry of the working surface of the pole piece is either hyperbolic, or trapezoidal, or polygonal shape (figure 3).

The number of the partial fractions in a mixture of non-magnetic material is equal to the number of sites interpolar gap and the number of pairs of pole pieces. Value minyukova gap between a pair of pole pieces, the geometry of their profile, the amount of the air gap Δ1and Δ2for each pair of pole pieces are chosen from the condition ρkk+1where ρ is the effective density of the magnetic fluid, k is the sequence number of the segment.

In the inventive magnetohydrostatic separator is used, the effect of changing the effective density of the magnetic fluid located in an inhomogeneous magnetic field. In this case, per unit volume of magnetic fluid acting magnetic force fmin the direction of increasing magnetic field strength

fM0·M·|∇H|,

where µ0- magnetic permeability of vacuum, M is the magnetization of the ferrofluid, |∇H| is the module of the gradient output the items of the magnetic field.

If the direction of gravity (ρW·g) and the magnetic force fmmatch, then the effective density of magnetic fluid ρ exceeds the density ρWmagnetic fluid in the absence of magnetic field

Adjusting the effective density of magnetic fluid by changing the magnetic field strength can be influenced by the amount of Archimedean force and to carry out the separation of non-magnetic materials according to their density.

For the first pair of pole pieces, the minimum value of the gap δ1between them, the geometry of their profile and the magnitude of the current I in the winding are chosen from the condition that the effective density of the magnetic fluid exceeds the density of the heavy fraction in a mixture of non-magnetic materials

ρ1>(ρFmax.F,1),

where ρ1- the effective density of the magnetic fluid in the first section, ρF. max- the density of the heavy fraction in a mixture of non-magnetic material, ρF,1- the density of the heavy fraction in a mixture of non-magnetic material on the first segment.

As a result, all fractions of the mixture will be on the surface of the magnetic fluid.

For the second and each subsequent pair of pole pieces, the minimum value of the gap δtobetween them, the geometry of their profile are selected from the conditions of separation and the mixture fraction with density ρ F(k-1):

PF,k-1kF,k,

where ρk- the effective density of the magnetic fluid at the k-ω plot, RF,k-1- the density of the heavy fraction in a mixture of non-magnetic materials at the k-1-ω plot. ρF,k- the density of the heavy fraction in a mixture of non-magnetic materials at the k-ω plot.

Specific magnetic force fmin the top half filled with ferrofluid of the working gap can vary from a maximum value of fm maxto the minimum value of fm min. Respectively, and the effective density of magnetic fluid changes from ρmaxto ρmin.

The main requirement when selecting the profile geometry of a pair of pole pieces at each site, starting with the second (k≥2), is that the top half is filled with ferrofluid interpolar gap, the difference values of the effective density shall not exceed the difference between the densities of the partial fractions

k maxk min)<(ρF(k-1)F k).

Edges on the surface of the pole pieces directed toward the interpolar gap, rounded to eliminate concentration of magnetic field lines and sharp local changes effective density of magnetic fluid.

Magnetohydrostatics separator operates as follows.

In about ode magnetizing 2 set current I, required for retention in the working gap of the separator of the necessary quantity of magnetic fluid 5. By using the device control angle of the magnetic separator system set at an angle α to the horizon (0<α<45°), resulting floating on the surface of magnetic fluid particles will move along this surface in the direction of the output end of the separator. The angle α is selected from the conditions provide the necessary performance and accuracy of the process of the separator. From the boot device 6 to the surface of magnetic fluid in the zone of the first stage receives a mixture of non-magnetic particles to be separated. The magnitude of the current I in the winding 2 is proportional effect on the magnitude of the magnetic field and magnetic force fm. The current is regulated so that as the movement of the particles along the inclined surface of magnetic fluid was consistent separation of fractions by density in each area of the interpolar gap. Improving the accuracy of division of fractions by density produced by additional regulation intensity of the magnetic field within each section of the gap by moving the plates 8 and/or magnetic shunt 9. When lifting plates 8 magnetic resistance for the magnetic flux caused by the gap Δ1at Illichivets, which reduces the intensity of the magnetic field in the gap and reduce the force fm. When lowering the magnetic shunt 9 (figure 4) there is a reduction of the gap Δ2and strengthening effect of the bypass magnetic flux, so that the magnetic field strength in the interpolar gap and the power of the fmreduced.

In the end coming from the boot device 6 (2) a mixture of nonmagnetic materials are sorted by the density value on a separate faction within the container 7. In the proposed magnetohydrostatic separator in a single loading of the separated mixture increases the number of partial density fractions, which helps increase productivity and efficiency magnetohydrostatic separator.
