を分離する。This non-magnetic metal separator has a basic structure as shown in FIG. 2, and includes a top pulley 1, a tail pulley 2, and a conveyor belt 3 wound around the outer periphery of both pulleys. Inside the top pulley 1 made of a non-magnetic material, there is provided a rotating magnet body 4 having different strong magnetic poles alternately arranged at equal intervals on the outer peripheral surface thereof. When the conveyor belt 3 is moved at a relatively low speed by driving the drive belt 21 in the direction of the arrow, and the rotary magnet body 4 is driven and rotated by the drive belt 41 at a high speed in the same direction, it is placed on the conveyor belt 3. The mixture M to be separated passes through a magnetic field formed by the rotating magnet body 4. When a non-magnetic metal 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 a magnetic field generated by the rotating magnet 4 cause a strong force in the moving direction of the conveyor belt 3. Thrust works, and a first separation box 5 provided at a location away from the top pulley 1
To fall. Further, a ferromagnetic material such as an iron material is driven by a magnetic field formed on the surface of the rotating magnet body 4 so that the conveyor belt 3
The conveyor belt 3 falls onto a third separation box 6 disposed at a position away from the top pulley 1. Further, the non-metallic body falls into the second separation box 7 located in the middle of the separation and collection box of the non-magnetic body and the magnetic body, and separates the object according to its magnetic characteristics and electric conduction characteristics.

めて推力付与による分離を困難にする。However, when a conventional rotating magnet body 4 in which different magnetic poles are alternately arranged is used, a magnetic field MF for forming a magnetic field is directed to another adjacent magnetic pole as shown in FIG. It is in a state of sleeping. For this reason, a vertically oriented magnetic field portion that generates thrust on the non-magnetic metal is small, 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 by applying thrust difficult.
【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 a lying state to a rising state.

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

し、磁界の立ち上がりが逆に装置の分離能力を低下する
という欠点を生じる。However, in the method of forming such a rising magnetic field, the lines of magnetic force formed by the rotating magnet body are largely dissipated. Due to the dissipation of this magnetic field, an induced current to the non-magnetic metal, and furthermore, a discharge The drawback is that the thrust is reduced and the rise of the magnetic field conversely reduces the separation capability 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 It is an object of the present invention to provide a device for separating non-magnetic metal by a thrust caused by an induced current formed by rotation of a rotating magnet body without causing a magnetic field to be dissipated. It is to provide an efficient means for starting a magnetic field.

する異極形成体を配置したことを特徴とする。According to the present invention, there is provided a non-magnetic metal separating apparatus for rotating a rotating magnetic body and discharging a non-magnetic metal piece by a thrust by an induced current induced by a magnetic field from the rotating magnetic body. The rotating magnetic body is formed by a plurality of magnets of the same polarity that are 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 disposed above and outside the rotating magnetic body. .

【００１２】さらに、この異極の磁石は回転磁性体の上

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 material which emits the non-magnetic metal piece forms a parallel and linear magnetic field which goes straight toward the opposite pole outside the rotating magnetic material, 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 material.
【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 radiate spontaneously, and the induction current is formed efficiently.

の位置を完全に同調し、一致させることができる。In FIG. 1, magnets 8 having N poles arranged on the outer surface side are arranged at equal intervals in the rotating magnet body 4 arranged inside the top pulley 1. Reference numeral 9 denotes a rotary magnet body disposed above the top pulley 1 and at a position close to the discharge end of the conveyor belt 3 that conveys the material M to be separated. The magnets 10 are provided such 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 this upper position is the top pulley 1
The rotary magnet body 4 is rotated by a drive belt 91 hung on a drive shaft 42 of a rotary drive belt 41 of the rotary magnet body 4. The peripheral speed due to the rotation of the rotating magnet body 9 is determined by the ratio of the diameter of each of the drive shafts 42 and 92 according to the ratio of the diameter of the rotating magnet body 9 to the diameter of the rotating magnet body 4 in the top pulley 1. It is matched by changing. Thereby, even if each of them is rotating, each magnet 8 of the rotating magnet body 4 in the top pulley 1 and the magnet 10 of the different pole side rotating magnet body 9
Can be perfectly tuned and matched.

As a result, no rotational force is generated between the induced current and the magnetic field induced in the non-magnetic metal, and the non-magnetic metal material M
By applying a thrust to 1 , the non-metallic material M 2 and the magnetic metallic material M 3 can be reliably separated.
