Definitions
- the invention relates to a device for separating ferromagnetic particles from a suspension, comprising a tubular reactor through which the suspension can flow, with an inlet and an outlet and with a means for generating a magnetic field.
- the ore is ground to powder and the resulting powder mixed with water.
- This suspension is exposed to a magnetic field generated by one or more magnets, so that the ferromagnetic particles are attracted, whereby they can be separated from the suspension.
- DE 27 11 16 A a device for separating ferromagnetic particles from a suspension is known in which a drum consisting of iron rods is used. The iron rods are alternately magnetized during rotation of the drum, so that ferromagnetic particles adhere to the iron rods, while other components of the suspension fall between the iron rods.
- a magnetic separator is described in US 4,921,597 B.
- the magnetic separator has a drum on which a plurality of magnets are arranged.
- the trumpet mel is oppositely rotated, so that ferromagnetic particles are anhaf ⁇ th and separated from the suspension to the drum to the flow direction of the suspension.
- a process for the continuous magnetic separation of suspensions is known from WO 02/07889 A2. There, a rotatable drum is used, in which a permanent ⁇ magnet is attached to deposit ferromagnetic particles from the suspension.
- the invention is therefore based on the object to provide a Vorrich ⁇ device for separating ferromagnetic particles from a suspension, which is able to separate ferromagnetic particles with high purity ⁇ .
- the invention is based on the idea that the ferromagnetic particles can be concentrated by the externally generated and applied to the suspension magnetic traveling field and thus deposited with higher purity.
- the magnetic traveling field thereby moves essentially in the longitudinal direction of the reactor from the inlet to the outlet, at which point the ferromagnetic particles are separated from the suspension.
- the course of the traveling field or the variation of the magnetic field strength ⁇ tables corresponds to a sine function, where ⁇ with the field strength between a low value and changes to a high value and the transition is continuous.
- the ferromagnetic particles are moved radially outward inside the reactor, so that they gradually accumulate on the inner wall of the reactor ⁇ . In the region of the outlet of the reactor, the ferromagnetic particles can then be deposited.
- a preferably cylindrical displacement body is arranged in the tubular reactor.
- the displacer causes the suspension in the reactor to pass through an annular gap.
- a preferably annular aperture for separating Magneti ⁇ rule and non-magnetic components of the suspension is arranged at the outlet. Due to the magnetic traveling field, the concentration of the ferromagnetic particles flowing past the outlet fluctuates. It is therefore advantageous that the ferromagnetic particles are precipitated when their concentration is high and that they are not precipitated when their concentration is low.
- the diaphragm can be opened when the concentration of passing ferromagnetic particles is high. If the current concentration of ferromagnetic particles is low, the iris can be closed.
- the opening cross-section of the aperture is controllable to adjust intermediate stages between a fully open or fully closed aperture.
- the opening cross-section of the diaphragm depends on the speed of the current amplitude or phase of the traveling field is controllable.
- the control of the diaphragm can be adapted to the magnetic traveling field, so that the deposition of the ferromagnetic particles preferably takes place when their concentration is high, which is accompanied by a correspondingly strong local magnetic traveling field at the outlet.
- the aperture is completely closed.
- a complete closure of the diaphragm may be useful if the proportion of ferromagnetic particles in the currently flowing past the outlet suspension is very low.
- the valve may comprise a bellows for adjusting the opening cross-section, which is preferably actuated electromagnetically or pneumatically or hydraulically. With this bellows, the annular space or the annular cross section in the region of the outlet of the reactor can be completely or partially closed.
- the inventive apparatus may comprise a suction pump whose suction side opens into the reactor. With the suction pump ferromagnetic particles can be seen, which are moved under the influence of the magnetic traveling field radially outward to the inner wall of the tubular Re ⁇ actuator sucked.
- the suction pump is arranged in the region of the outlet of the reactor. The negative pressure generated by the suction pump separates the ferromagnetic particles from the suspension.
- the suction pump can be controlled as a function of the current amplitude and / or phase position of the traveling field. Due to the temporal coordination of the suction process by the suction pump and the attraction of the ferromagnetic particles by the magnetic traveling field, the suction pump can be controlled so that it sucks the ferromagnetic particles exactly when they flow past in increased concentration on the suction side.
- the suction pump is designed as a diaphragm pump.
- the diaphragm pump can be controlled so that the Pumpbewe ⁇ tion is synchronized with the magnetic traveling field.
- the stroke volume of the diaphragm pump is selected so that the magnetic constituents discontinuously supplied by the magnetic traveling field are substantially sucked off.
- the erfindungsge ⁇ Permitted device comprises a pump for conveying the separated magnetic components, which is connected to a bypass line.
- a pump for conveying the separated magnetic components, which is connected to a bypass line.
- the pump prevents the deposited ferromagnetic particles in a pipeline deposit and clog them.
- Through the bypass line is a continuous promotion of istschie ⁇ which ferromagnetic particles.
- a throttle can be located in the bypass line, whereby the flow in the bypass line can be regulated.
- FIG. 1 shows a first embodiment of a erfindungsge ⁇ MAESSEN device in a partially sectioned perspective view.
- 2 shows a second embodiment of the invention in a sectional view.
- Fig. 3 shows a variant of execution shown in Figure 2 ⁇ example.
- Fig. 4 shows a further embodiment of a device according to Inventive ⁇ .
- the device 1 shown in Fig. 1 comprises a reactor 2, which is tubular. Via an inlet 3, a suspension is fed to the reactor 2 which contains ferromagnetic particles 4 and undesired constituents such as sand, ore, etc.
- ferromagnetic particles 4 are shown in spherical form by way of example, but the undesired components of the suspension are not shown.
- the suspension flows through the reactor 2 in the direction of the arrow 5.
- a cylindrical displacement body 6 In the center of the reactor 2 is a cylindrical displacement body 6, so that in the interior of the reactor 2, an annular gap is formed through which the suspension flows.
- a traveling field magnet 7 which is operable by an electric or electronic control so that it generates a traveling magnetic field which is moved in the longitudinal direction of the reactor 2.
- the magnetic traveling field leads to a concentration of the ferromagnetic particles 4 on the inner wall of the reactor 2.
- the ferromagnetic particles are under the influence of the magnetic field radially outward emotional.
- the ferromagnetic particles 4 do not accumulate homogeneously on the inner wall of the reactor 2, but instead the suspension flowing past has portions with an increased concentration of the ferromagnetic particles as well as portions with reduced concentration of the ferromagnetic particles.
- a diaphragm 9 is arranged to separate ferromagnetic particles and non-magnetic particles from each other. As shown in Fig. 1, divides the annular aperture 9 the annular space between the in ⁇ inner side of the reactor 2 and the displacement body 6 into two concentric annular gaps 10, 11 the concentration of the ferromagnetic particles is higher than in the in the outer annular gap 11 inner ring gap 10. The fraction of the suspension in the outer annular gap 11 is separated during or after passing through the aperture 9.
- FIG. 2 shows a further exemplary embodiment of a device for separating ferromagnetic particles from a suspension, wherein the same reference numerals as in FIG. 1 are used for matching components.
- the Vorrich ⁇ device 12 which is shown in Fig. 2 cut and only partially shown, the reactor 2 with the traveling field magnet 7 and the displacement body 6.
- the diaphragm 13 which divides the interior of the reactor 2 into an inner annular gap 10 and an outer annular gap 11.
- the opening cross section of the outer annular gap 11 can be turned by means of a valve ⁇ is formed as a bellows fourteenth
- the bellows 14 is made of an elastic material, for example of an elastomer, and is movable between a closed position 15 and an open position 16, which is indicated by dashed lines. In the closed position 15, the flow through the outer annular gap 11 is prevented, in the open position 16, the fraction of the suspension with a high proportion of ferromagnetic particles 4 the pass outside annular gap 11 and be discharged via a pipe 17 in the arrow direction.
- the drive of the bellows 14 takes place electromechanically in the illustrated embodiment, for example, by a driven by an electric motor reciprocating plunger. Alternatively, the bellows 14 may also be moved pneumatically between the closed position 15 and the open position 16.
- the bellows 14 extends in the circumferential direction over the entire circumference of the reactor 2, so that the ferromagnetic material 4 can be Letschie ⁇ on the entire peripheral surface ⁇ the.
- the device 12 further comprises a controller 18, which is connected via electrical lines, not shown, with the traveling field magnet 7 and the bellows 14. By the controller 18, the magnetic traveling field generated by the traveling field magnet 7 with the opening and
- the Synchronisa ⁇ tion is carried out such that the bellows is opened when the proportion of ferromagnetic particles in the suspension is high, analogously, the bellows 14 is fully or partially closed when the proportion of ferromagnetic particles of the momentarily passing the outlet 8 suspension is low ,
