Definitions

  • the invention relates to a high gradient magnetic separator according to the preamble of the first claim.
  • the elements of the matrix structure are represented by the outer Magnetized field and in turn form magnetic poles that reinforce or weaken the outer field in places.
  • the resulting high field strength gradients result a strong magnetic force on para- or ferromagnetic particles towards higher field strength.
  • the particles adhere to the induced magnetic poles of the matrix and are therefore from the Fluid separated.
  • the Inlets are arranged so that the fluid flow into one with enriched magnetizable particles and divided the residual current and is discharged separately from the device.
  • a device for a continuous magnetic separation possibility with a significantly lower tendency to clog in continuous operation is described in [3]. It is crucial that the separation zone with an elongated cross-section, into which the particle-containing Fluid is introduced, a non-magnetizable Has wall.
  • a magnetic field is applied to the separator, whose field lines are ideally perpendicular to the flow direction and perpendicular to the longest axis of symmetry of the Flow cross-section run in the separation zone.
  • To the for the magnetic separation of ferro-, para- and diamagnetic Particles to generate required magnetic field gradients, is parallel to the flow direction on one end the elongated cross section of the separation zone is a single one magnetizable wire arranged.
  • the Device is further described in [4], being an additional Embodiment the arrangement of two magnetizable Wires (instead of a wire) on each end the elongated cross section of the separation zone parallel to the flow direction is shown.
  • Design-related is in the described embodiment with a certain Size to calculate, which the possible uses of this version limited especially for larger fluid throughputs.
  • a high gradient magnetic separator of the type mentioned with a very compact matrix-shaped cross-sectional design the separation zone, which is for real occurring, d. H. larger fluid flows, however, is described in [5]. It it is proposed alternating with magnetizable wires in parallel line-shaped to these arranged rectangular channels to arrange, the individual lines by paramagnetic Intermediate plates are separated from each other. For the process of Separation is a magnetic field perpendicular to the lines and the Intermediate plates created. A practical test of the concept is described in [5] just as little as a technical solution for the supply and discharge of the fluid to be separated.
  • the object of the invention is the channels in the region of the separation zone to be designed in such a way that a further increase in efficiency compared to the state of the art. Further should be a technically feasible and separated on the partial flows Fluid precisely coordinated derivation for the partial fluid flows be provided.
  • the enrichment takes place from a view in the direction of flow magnetizable particles in the separation zone in compared to the line structure rotated by 90 ° segments of the elliptical or circular channels.
  • Fig. 1 shows the structure with all modules of the invention High gradient magnetic separator. Via inlet 1 and the distributor 2, the fluid stream a enters the separation zone, contained in the separator block 3.
  • the division of the Fluid flow a ideally into a partial flow with and without Magnetizable particles b and c take place in the so-called fragment block 4, which also the processes 5 of the Fluidteistroms c (without magnetizable Particles) contains.
  • the partial fluid flow b (with magnetizable Particles) passes through the splinter plate 6 to Collector 7, which with the end plate 8 its constructive conclusion takes place and flows into the outlet 9 for the partial fluid flow b.
  • the separator block 3 and part of the splitter block 4 is located between the pole pieces 10 of a permanent magnet system, which generates a magnetic field H in these areas.
  • the aforementioned components of the high gradient rejection separator are in the embodiment shown in Fig. 1 by a clamping device 11 (for example by threaded rods clamped against each other and sealed become. 1, lines A, B, C and D are shown, which the position of those shown in Figures 2 to 4, 6 and 7 Cutting planes through the described high gradient repulsion separator define.
  • the section through the separator block 3 according to the plane A in Fig. 1 shows FIG. 2.
  • the separator block 3 consists of a non-magnetic one Material and is continuous, matrix-shaped in several lines parallel to each other and perpendicular to Provided section plane holes in which ferromagnetic Wires 13 are inserted. With the exception of the first and last row are in each row between two wires 13 parallel to each one through the entire separator block 3 continuous flow channel 14 with circular Cross section arranged, with flow channels 14 and wires 13 due to the non-magnetic material of the separator block 3 from each other are separated.
  • the direction of during the continuous Operation required magnetic field H (arrow in Fig. 2) perpendicular to the planes, which are arranged in the rows ferromagnetic wires 13 and channels 14 are formed.
  • the bores 12 in the separator block are also in FIG. 2 3 for the clamping device 11.
  • Fig. 3 shows the cross section of the splinter block 4 along the Section line B in Fig. 1, d. H. immediately after the Separatoblock 3 and still under the influence of the magnetic field H.
  • the cross-section of the splinter block consequently corresponds 4 largely in this area that of the separator block 3 and differs only in that the channels 14 for division of the fluid flow a into the two fluid partial flows b and c, respectively by two partition walls 17 arranged perpendicular to the magnetic field H. divided into a central channel 16 and two side channels 15 are.
  • the central channels 16 in Area between the collecting channels 18 and the transition to the Splitter plate 6 or at this end, the side channels run 15 through the entire splinter block 4.
  • the splitter block 4 is replaced by a splitter plate 6 (see Fig. 5) completed. This indicates where the Side channels 15 end, slot openings 19. This can the partial fluid flow b from the side channels 15 into the collector 7 pass and the high gradient magnetic separator over the drain 9 leave.
  • the central channels 16, however, are by the Splinter plate 6 tightly closed.
  • FIG. 6 shows an alternative design of the splinter blocks 4 with the subsequent components for deriving the partial fluid flows b and c as a section along that shown in Fig. 1 Line D.
  • the basic structure of the splinter block differs in the aforementioned embodiment in that the collecting channels 18th at the outlet from the splinter block closed by plugs 20 are and the derivation of the with the magnetizable Particles of depleted partial fluid flow c via from the central channels 16 is initially carried out in connecting pipes via the collecting channels 18, which in the extension of the in this version the entire splinter block 4 through holes for the ferromagnetic wires 13 are used, the corresponding constructively adapted sliver plate 25 and the collector 7 and bridge the plate 26 for the partial fluid flow b and into one downstream common solution collector 22 open.
  • Fig. 7 shows a schematic diagram of a further, alternative Embodiment of the separator block 3, consisting of a non-magnetic Housing 28, which is a stack also non-magnetic Shaped elements 27 as guide elements for the ferromagnetic Includes wires 13.
  • the channels 14 of the separator block 3 incorporated into the shaped elements 27 as recesses.
  • the design of the shaped elements 27 are so constructive designed so that the matrix around each line, consisting of ferromagnetic Wires 13 and channels 14, with two around each 180 ° rotated molded elements 27 can be assembled.
  • the arrangement within the stack requires space to be filled the matrix with non-magnetic material, which is basically the one before 2 corresponds to said monolithic embodiment, but from much easier to manufacture components consists.
