た非磁性導電材料分離装置が提案された。 Mixed materials collected as waste can be broadly classified into the above-mentioned magnetic materials, non-magnetic conductive materials, and non-magnetic non-conductive materials, and various magnetic materials using the magnetic attraction force of magnets are used to separate magnetic materials. A sorting machine has been proposed. In addition, in order to separate materials from which magnetic materials have been removed in advance by a magnetic separator or the like into non-magnetic conductive materials and non-magnetic non-conductive materials, the inventor of the present application has disclosed a patent application in Japanese Patent Application No. 53-98711.

向に向けられる。 The separation device includes a cylindrical body disposed substantially laterally and driven and rotated in one direction about a longitudinal central axis as a rotational axis, and a cylindrical body surrounding the cylindrical body and coaxial with the cylindrical body about the rotational axis. and means for generating a magnetic field rotating in the opposite direction. Materials from which magnetic materials have been removed in advance are charged into the cylindrical body, and non-magnetic non-conductive materials other than non-magnetic conductive materials among the materials loaded into the cylindrical body are rotated in the direction of rotation of the cylindrical body. directed towards. Further, the non-conductive material is oriented in a direction opposite to the rotational direction of the cylindrical body by an electromagnetic force between an eddy current generated inside the non-conductive material by the rotating magnetic field and the rotating magnetic field.

非導電材料とを分離することができる。 Therefore, according to the separation device, by rotating the rotating magnetic field, which rotates in the opposite direction independently of the cylindrical body, at a high speed, the material introduced into the cylindrical body can be separated from the material without applying a strong centrifugal force to the material. A strong electromagnetic force can be applied to the magnetic conductive material, thereby effectively separating the non-magnetic conductive material from the non-magnetic non-conductive material.

妨げられることがあつた。 However, the separation device cannot separate the magnetic material, and if there is any magnetic material remaining in the input material, the remaining magnetic material is absorbed into the cylindrical body which rotates due to the magnetic attraction force of the rotating magnetic field. Since it is adsorbed and held on the inner circumferential surface or is stirred together with the non-magnetic non-conductive material in the cylindrical body without receiving the magnetic attraction force, the remaining magnetic material causes the non-magnetic conductive material and the non-magnetic non-conductive material to be separated. Separation from the government was sometimes hindered.

This causes an electromagnetic force to be exerted on the non-magnetic conductive material in the mixed material in a direction opposite to the rotational direction of the cylindrical body, and the magnetic attraction force of the rotating magnetic field causes the non-magnetic conductive material in the mixed material to A magnetic material is held on the inner circumferential surface of the cylindrical body and released from the inner circumferential surface in a predetermined rotation region, and means is provided inside the cylindrical body for receiving the magnetic material released from the inner circumferential surface.

At this time, the non-magnetic conductive material 68 represented by an aluminum can in the mixed material 64 is
The magnetic flux of the rotating magnetic field is relatively crossed when passing through the rotating magnetic field area without receiving the magnetic attraction force due to the rotating magnetic field of the outer ring 36. Therefore, an eddy current is induced in the conductive material 68, and due to the electromagnetic force of the eddy current and the rotating magnetic field, the conductive material 68 moves toward the cylindrical body 12 as shown in FIG.
It is directed toward the lower end opening 62 of the cylindrical body 12 in a state where it is biased along the bottom of the cylindrical body in a direction opposite to the direction of rotation of the cylindrical body.

The magnetic material 72, represented by a piece of iron except zero, does not pass through the rotating magnetic field region along the bottom of the cylinder 12. That is, the magnetic material 72 in the mixed material 64 rotates integrally with the cylindrical body 12 while being adsorbed and held on the inner peripheral surface of the cylindrical body 12 by the magnetic attraction force in the rotating magnetic field region. The magnetic material 72 is released from the inner circumferential surface of the cylindrical body 12 in a predetermined rotation region where the distance between the magnetic material 72 and the outer ring 36 becomes large, and the released magnetic material 72 is received by the belt conveyor 58, which rotates the cylindrical body. 1

が望ましい。 The conductive material 68 generally has a shape that is easy to roll, such as an aluminum can, and has a higher specific gravity than the non-conductive material 70.
In order to effectively apply the electromagnetic force to the conductive material 68 which is in a dense state on the side opposite to the direction of rotation of the cylindrical body 12 from the perpendicular line L1 ,
As described above, it is preferable to provide the closest point P 1 on the side opposite to the rotational direction of the cylindrical body 12 with respect to the perpendicular line L 1 . Further, in order to prevent the conductive material 68 and the non-conductive material 70 from being mixed together, a separation plate (not shown) may be disposed close to the lower edge of the lower end opening 62 of the cylindrical body 12. desirable.

Further, as a means for receiving the magnetic material, a receiving tray or the like that can be taken in and out of the cylindrical body 12 may be used instead of the belt conveyor or the gutter. It is preferable to use a belt conveyor or gutter having a conveying function as described above.

る。 Although FIGS. 1 and 2 show an example in which both the rotation axes a 1 and a 2 of the cylindrical body 12 and the outer ring 36 are inclined, it is also possible to make both the rotation axes a 1 and a 2 horizontal. Can be done. In this case, the conductive material 68
Also, since it becomes impossible to continuously discharge the non-conductive material 70 from the lower end opening 62 of the cylindrical body 12, it becomes necessary to take out both parts separated within the cylindrical body 12 from the cylindrical body. .
Furthermore, by tilting the magnetic pole boundaries of the magnets 38 and 40 of the outer ring 36 with respect to the central axis a 2 , a force component along the central axis a 2 is imparted to the electromagnetic force according to the direction of inclination. This allows the conductive material 68 to be connected to the upper opening 6 of the cylindrical body 12.

As shown in the figure, a scraper 7 for scraping off magnetic material from the inner peripheral surface of the cylindrical body 12 onto the belt 54.
Alternatively, a magnetic member 76 such as an iron plate may be provided as a magnetic shield between the cylindrical body 12 and the magnetic device 14 on the upper side of the cylindrical body 12.
can be provided. Eddy current is generated in this magnetic member 76 by the rotating magnetic field, and this eddy current gives rotational resistance to the outer ring 36. Therefore, in order to lower this rotational resistance, the magnetic member 76 is made of a laminated layer that is less likely to generate eddy current. It is desirable to use a structure or a mesh structure.
