Description of the Related Art In a conventional magnetic separator, generally, a plurality of magnets are arranged on the outer periphery of a rotating drum with their directions changed, and the raw material flowing on the outer periphery of a cylindrical body arranged outside the magnets is separated from the raw material. The magnetic deposit was separated. However, since the adjacent magnets are arranged with different poles, the magnetic lines of force formed near the surface of the cylindrical body have an arch shape, and a non-magnetic material is included in the magnetically attracted material attracted to the adjacent magnetic poles. In such a case, the magnetic field is moved, and as a result, there is a problem that the separation efficiency of the magnetically attached matter is poor. Therefore, as described in JP-B-57-43310 and JP-B-62-54547, the magnets arranged around the drum are made to have the same polarity and the magnetic force lines generated from the magnets are substantially perpendicular to the cylindrical body. To prevent arching of the lines of magnetic force.

ることを目的とする。However, in the magnetic separator described in the above-mentioned publication, since the magnets are arranged in the same polarity, the magnetic flux density passing through the side circumference of the cylindrical body is reduced, and the minute magnetically attached material is reduced. However, there is a problem that it is difficult to sufficiently sort the garbage. Therefore, in the conventional magnetic force sorter, it is difficult to remove a fine magnetic substance having a size of 1 to 10 μm or less by using a magnetic force sorter in which magnets are arranged in different polarities and a magnetic force sorter in which magnets are arranged in the same polarity. There was a problem that is. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a magnetic force separator capable of performing sufficient magnetic force separation by increasing the generated magnetic flux density.

The magnetic guide member 14 is provided at a certain distance from the magnetic substance transport plate 13 so that the raw material can sufficiently pass therethrough. The magnetic induction member 14 is made of an iron plate and collects magnetic fluxes from the permanent magnets 12 that generate a magnetic field in the magnetic force sorting unit 18 so that a strong vertical magnetic field can be generated by the magnetic force sorting unit 18 through which the raw material passes. . Note that it is also possible to bend both sides of the magnetic induction member 14 along the outer shape of the magnetic force sorting unit 18 formed of a rectangular cylinder, and to face both sides of the cylindrical body 11 made of a magnetic material with a small distance.

When the cylindrical body 11 is rotated in a predetermined direction and the raw material is gradually introduced from the upper raw material charging port 24, the raw material slides down on the drop guide plate 16 and the magnetically attached material transporting plate 13, but the magnetically attached material 21 contained therein is magnetic. While being attracted to the kimono transporting plate 13, it moves downward by the rotation of the inner permanent magnet 12 and moves onto the magnetic separation plate 17. When moving on the magnetic separation plate 17, the magnetic field of the permanent magnet 12 gradually disappears, so that it finally falls from the end of the magnetic separation plate 17 by gravity and is stored in the container 23. In this case, since the magnetic flux in the magnetic force sorting unit 18 moves in a state substantially orthogonal to the flow of the raw material, the non-magnetic material is separated without being pressed by the magnetic material, and as a result, the separation efficiency of the magnetic material is improved.

る。EXAMPLES Using the magnetic separator 25 according to the second embodiment, the particle size is mainly fine polish silica sand of about 1～90Myuemu, yet during this fine polish silica sand iron (Fe 2 O 3) When a raw material liquid containing 0.7 to 1.2% by weight was charged from the raw material liquid supply hopper 35 and subjected to magnetic separation by a wet method, the concentration of iron in the liquid product was 0.04 to 0.1. To 08% by weight. In this case, the magnetic flux density of the raw material liquid passage section 28 was about 6500 gauss. On the other hand, when the raw material liquid is passed through a conventional wet magnetic separator in which permanent magnets having different polarities are alternately arranged to perform magnetic separation, the iron content of the iron removal product is still 0.4 to 0.8% by weight. It can be seen that the magnetic substance is not effectively separated. The particle size is 1 to 10
In the case of a raw material liquid containing 0.2 to 0.5% by weight of fine iron particles having a particle size of 0.2 μm, if magnetic separation is performed by a conventional magnetic separator, the iron remaining in the iron-removed product is large, and as a result, the magnetic separation is reduced. could not. On the other hand, when the magnetic separator 25 according to the embodiment is used, the remaining iron content is 0.04 to
It can be seen that the magnetic separator according to the present invention is particularly effective when the magnetic particle separator has a small particle size of 0.08% by weight and contains magnetic particles.
