り板を示している。 In view of these points, the present inventors have conducted various studies. At this stage of consideration, we proposed, for example, a separation device as shown in Figs. 1 and 2 using the magnetic field generator shown in Figs. ing. In this device, as shown in FIGS. 3 and 4, a gently spiral slot 8 is provided on the outer peripheral surface of a magnetic cylinder 7, and a coil 9 is embedded in the slot 8 to create a traveling magnetic field 10 containing a rotating component. A magnetic field generating device 1 that generates a magnetic field is built into the cavity housing 2, and a traveling magnetic field 1 is applied to the fluid W0 flowing in from the inlet 5.
0 acts, the magnetic powder X is separated, drawn toward the N side, and taken out from the outlet 4. In the figure, 3 indicates an outlet from which the treated fluid W1 is taken out, and 6 indicates a partition plate.

逸早く磁気的に飽和してしまい、結果的には外周
面１１での進行磁界の増加は達成しなくなる。 In the case of such a structure, in order to generate a larger traveling magnetic field in order to improve the separation efficiency, it is necessary to increase the number of turns of the coil by increasing the current flowing to the coil of the magnetic field generating device 1 or by increasing the cross section of the slot 8. However, when doing this, the distance between the coil 9 and the adjacent coil 9' becomes narrower as the magnetic cylinder 7 goes inside, that is, as the diameter becomes smaller, and for this reason, when a large current is passed through the coil, this part quickly becomes magnetic. As a result, the traveling magnetic field on the outer circumferential surface 11 cannot be increased.

のである。 A feature of the present invention that achieves this object is that the coil is appropriately inclined on the inner circumferential surface and wound at 3/4 full pitch so as to generate a traveling magnetic field containing a rotating component in the middle of the fluid passage and on the outer periphery of the passage. A cylindrical alternating magnetic field generator is arranged so that the traveling magnetic field is applied to the fluid flowing along the passage, and the magnetic particles mixed in the fluid are removed by the magnetic field generator. The embodiment of the present invention includes a fluid inlet on one side of the upper and lower sides and an outlet on the other side in the middle of the fluid passage. further provided with a second outlet at the lower part,
A non-magnetic cavity housing having a partition plate extending vertically is arranged between the lower inlet or outlet and the second outlet, and a rotating component is removed from the fluid mixed with magnetic powder that flows in from the fluid inlet. The present invention includes a magnetic powder separation device configured to apply a traveling magnetic field containing the magnetic powder from the outer periphery of the cavity housing to separate the magnetic powder and take out the magnetic powder from the second outlet.

A plurality of slots 23 whose cross section is inclined with respect to the axis as shown in FIG. 6 are provided on the inner peripheral surface 21a of a magnetic cylinder 21 made of a magnetic material. A long coil 22 having a large number of windings and insulated is buried in this slot 23.

もそれは大電流に至るまで保たれる。 The present invention has the above structure, and since the magnetic pole is on the inner circumferential surface, the concentration of magnetic flux is high, and even when a large current is passed through the coil, the magnetic saturation inside the magnetic pole of the magnetic cylinder 21, that is, the area where the diameter is large, is This cannot be done until the inner circumferential surface 21a reaches saturation, so that the current flowing to the coil and the strength of the magnetic field maintain a proportional relationship, and this is maintained even up to a large current.

となる。 Adjust the flow rate and pressure of the fluid W 0 containing magnetic powder and granules, and take it in from the inlet 25, and connect it to the magnetic field generator 2.
Operate 0. The non-magnetic fluid is pushed up to the outlet 26, but the mixed magnetic powder and granules are
Since a magnetic field is applied that rotates and moves downward as shown by the arrow f in Figures 0 and 11, the magnetic powder is concentrated at the bottom N of the left space through the partition plate 28 Ru. The magnetic powder X thus concentrated or unified is taken out from the outlet 27 continuously or intermittently.
In the above, as a result of experiments by the present inventors, when the six coils are appropriately inclined to form 3/4 full-pitch winding, there is no discontinuity in the magnetic field and it is possible to create a uniform magnetic density and magnetic field gradient. It was possible to transfer the magnetic powder by placing it on top of a magnetic field, and it was possible to increase the transfer rate of the powder. Therefore, the fluid W 1 flowing out from the outlet 26 does not contain magnetic particles at all, or the concentration of magnetic particles in the fluid W 1 is extremely low.
