を分離する。This non-magnetic metal separating device has a basic structure as shown in FIG. 2, and has a top pulley 1, a tail pulley 2, and a conveyor belt 3 wound around the outer circumferences of both pulleys. However, inside the top pulley 1 made of a non-magnetic material, there is provided a rotating magnet body 4 in which strong magnetic poles having different outer circumferential surfaces are alternately arranged at equal intervals. Then, the conveyor belt 3 is moved in the direction of the arrow at a relatively low speed by driving the drive belt 21, and the rotary magnet body 4 is driven and rotated by the drive belt 41 in the same direction at a high speed, and is placed on the conveyor belt 3. The mixture M to be separated passes through the magnetic field formed by the rotating magnet body 4. When a non-magnetic metal body such as aluminum is present in the mixture M to be separated, an induced current is generated in the non-magnetic metal, and the induced current and the magnetic field generated by the rotating magnet body 4 make it strong in the moving direction of the conveyor belt 3. The first separating box 5 provided at a position away from the top pulley 1 by the thrust
To fall. In addition, the ferromagnetic material such as iron material is generated by the magnetic field formed on the surface of the rotating magnet body 4 so that the conveyor belt 3
The conveyor belt 3 drops onto the third separation box 6 arranged at a position away from the top pulley 1 by being attached to the surface of the above and rotating. Further, the non-metal body drops into the second separation box 7 located in the middle of the separation and collection box of these non-magnetic body and magnetic body, and separates the objects according to their magnetic characteristics and current-carrying characteristics. To do.

めて推力付与による分離を困難にする。However, when the conventional rotary magnet body 4 in which different magnetic poles are alternately arranged is used, the magnetic field MF forming the magnetic field is directed to another adjacent magnetic pole as shown in FIG. Is in a sleeping state. Therefore, there are few vertically oriented magnetic field portions that generate thrust on the non-magnetic metal, and when the rotating magnet body 4 is rotated, the rotating force acts on the non-magnetic metal body on the conveyor belt 3 on the top pulley 1. Makes separation difficult by applying thrust.
【０００６】その問題は、回転磁石体による磁界が寝た
状態から立ち上がった状態にすることによって解決でき
る。The problem can be solved by changing the state of the magnetic field generated by the rotating magnet body from the sleeping state to the rising state.

石体の他の磁極に戻す方式が考えられる。Therefore, by arranging a ferromagnetic material such as an iron piece above the top pulley 1, the lines of magnetic force from the rotating magnet body are once directed to the opposing magnetic poles generated on the strong magnet body, and the ferromagnetic A method of returning from another part of the body to another magnetic pole of the rotating magnet body is conceivable.

という欠点を生じる。However, in such a method of forming the rising magnetic field, the magnetic lines of force formed from the rotating magnet body are often diffused, and the magnetic field is diffused to induce an induced current to the non-magnetic metal, and thus to release the magnetic field. The thrust is reduced, and the rise of the magnetic field adversely affects the separation ability of the device.

ための効率的な手段を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a device for separating a non-magnetic metal by a thrust of an induced current formed by the rotation of a rotating magnet body, by using the rotating magnet body without causing magnetic field dissipation. It is to provide an efficient means for raising the magnetic field.

The rotating magnetic body is formed by magnets of the same polarity divided into a plurality of parts, and a different pole forming body that forms a different pole with respect to the magnetic pole of the rotating magnetic body is arranged above the rotating magnetic body. ..

なし、また、その磁界は回転磁性体の方に戻ることはな
いので、分離物に回転力を与えることはない。The magnetic field from the rotating magnetic body that emits the non-magnetic metal piece forms a parallel rectilinear magnetic field that advances straight toward the outer poles of the rotating magnetic body, so that the non-magnetic metal piece is emitted. The magnetic field from the rotating magnetic body is in a completely raised state, and since the magnetic field does not return to the rotating magnetic body, no rotational force is applied to the separated object.
【００１４】また、立ち上がり磁界は外方に配置された
磁石に指向するので、自然放散することがなく、誘導電
流の形成効率はよい。Further, since the rising magnetic field is directed to the magnet arranged outside, it does not spontaneously dissipate and the formation efficiency of the induced current is good.

Reference numeral 9 denotes a rotary magnet body disposed above the top pulley 1 and near the discharge end of the conveyor belt 3 that conveys the substance to be separated M. The rotary magnet body 9 includes the top pulley 1 The magnets 10 are provided so that the S poles are arranged at equal intervals corresponding to the magnetic poles N on the outer surface side of the inner rotating magnet body 4.
The rotating magnet body 9 in the upper position is the top pulley 1
The rotary magnet body 4 is rotated by the drive belt 91 hung on the drive shaft 42 of the rotary drive belt 41.
