Description

[0001] The present invention relates to a horizontal rotating type wet eddy current separator,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal rotary type wet eddy current separator, and more particularly, to a horizontal rotary type wet eddy current separator capable of easily separating fine non-metal particles having a small size from non-metal particles.

In recent years, there has been a great deal of social interest in the recycling of waste resources for efficient use of limited resources in addition to environmental protection, and various measures have been proposed for this purpose.

For example, in recent years, a large amount of waste electronic products have been generated by the frequent replacement of electronic products due to the improvement of income level. In the past, these waste electronic products were crushed by a crusher to be made into small crumbs, It was common to ask.

However, in recent years, various sorting devices have been developed in order to select useful resources in the pulverized products of such waste electronic devices for resource recycling. In particular, non-ferrous metals such as Al, Mg, Cu, Sn, Pb, and Zn are mixed with non-metals such as plastics and ceramics.

1, a conventional non-ferrous metal and non-ferrous metal is introduced into a sloping surface 1 provided with a magnet M on the bottom surface thereof to produce eddy currents generated in the non-ferrous metal and magnets The non-ferrous and non-ferrous metals were selected by causing the non-ferrous metal to protrude by the repulsive force of the magnetic field generated by the non-ferrous metal.

However, the method of sorting the crushed materials by flowing down the slope does not significantly reduce the sorting efficiency, and particularly when the crushed materials are small (0.5 to 2.0 mm), it is difficult to select them.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a non-ferrous metal- The present invention is directed to a horizontal rotary type wet eddy current separator.

According to an aspect of the present invention, there is provided a horizontal eddy current eddy current separator comprising: a frame; A motor installed in the frame; A rotary table connected to the motor shaft of the motor and rotated; A plurality of magnet assemblies installed in a straight line spaced apart from the upper surface of the turntable by a predetermined distance; A frame wall installed on an upper surface of the frame and surrounding the periphery of the rotary table; A separating operation plate provided on the upper side of the frame, the separating operation plate having a vortex flow path in which a mixture of a conductor, an insulator and a fluid flows, And providing a mixture of the conductor, the non-conductor and the fluid to the vortex flow path.

Here, the mixture providing unit may include a water tank in which a mixture of a conductor, an insulator, and a fluid is stored; A guide pipe having one end connected to the water tub and guiding the mixture to the vortex flow path of the separating work plate; And a pump installed on the conduit of the guide pipe to flow the mixture.

And, the vortex-type flow path is formed so that its bottom surface is inclined so as to become higher toward the outside, and a backflow preventing jig is protruded from the bottom surface. Here, the inclined angle of the backflow preventing jaw with respect to the bottom surface of the vortex flow path is smaller than the outer surface of the backflow preventing jaw.

The magnet assembly includes a plurality of magnets facing each other, and the same poles of the magnets are disposed opposite to each other, and a diaphragm made of pure iron is provided between the same poles of the magnets facing each other.

The horizontal rotating type eddy current separator of the present invention having the above structure has an advantage that a non-ferrous metal mixed with a non-metal can be easily selected by a magnetic field generated by the rotation of the magnet. Particularly, when the non-ferrous metal of fine particles is mixed with the fluid (water), the non-ferrous metal can not bounce out of the vortex flow channel even if the repulsive force by the eddy current acts, and the nonmetal gathers on the outside of the vortex flow channel. There is an advantage that the separation of the non-ferrous metal having particles and the non-metal can be facilitated.

In addition, since a magnet is provided on a rotating table provided at the upper end of a motor shaft whose rotation speed is freely adjusted, the rotation speed of the magnet can be easily adjusted. Therefore, the magnetic flux density can be controlled by adjusting the rotation number, There is an advantage.

In addition, since a partition plate made of pure iron is provided between the magnets, the magnetic flux density is greatly increased, and the sorting efficiency can be further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a horizontal rotary type wet eddy current separator according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a perspective view showing a horizontal rotary type eddy current separator according to the present invention, FIG. 4 is a cross-sectional view showing a swirl flow path of a horizontal rotary type wet eddy current separator according to the present invention, FIG. 3 is a simplified view of the entire system of a horizontal rotary type wet eddy current separator according to the present invention.

A horizontal rotary type wet eddy current separator according to the present invention includes a frame 10, a motor 20 installed in the frame 10, a rotary table 30 connected to a motor shaft of the motor 20, A plurality of magnet assemblies 40 provided on the upper surface of the rotary table 30, a rim wall 50 provided on the upper surface of the frame 10, a separating member for raising and lowering a mixture of conductors, A work plate 60 and a mixture providing unit 70 for providing a conductor, a non-conductor and a fluid mixture to the separating work plate 60.

The frame 10 supports various components of the present invention as described above, and functions as a mount on which the components are installed.

The motor 20 is installed on the lower side of the frame 10, and the motor 20 provides rotational force to the rotary table 30. The motor 20 can freely adjust the rotational speed of the motor shaft, and can freely rotate forward or reverse.

The rotary table 30 is horizontally installed on the upper surface of the frame 10 and connected to the motor shaft of the motor 20 to perform forward rotation or reverse rotation together with the motor shaft.

The magnet assembly 40 is installed straight on the upper surface of the rotary table 30 with a predetermined distance therebetween. That is, when one magnet assembly 40 is installed on the left side of the upper surface of the rotary table 30, another magnet assembly 40 is installed on the right side of the top surface of the rotary table 30 facing straight. Although only two magnet assemblies 40 are shown in the figure, four magnet assemblies 40 may be provided, or more.

The magnet assembly 40 includes a casing 41, a plurality of magnets 42 provided inside the casing 41, and a diaphragm 43 provided between the magnets 42.

The casing 41 is fixed to the upper surface of the rotary table 30.

The magnets 42 are provided as permanent magnets facing each other inside the casing 41, and the same poles of the magnets 42 are arranged to face each other. That is, when two magnets 42 are disposed adjacent to each other on the left and right sides, when the N pole of the magnet 42 on the left side is arranged to face the right side, the N pole of the magnet 42 on the right side faces the left side . By doing so, the N poles of the two magnets 42 face each other.

The diaphragm 43 is disposed between the magnets 42 facing the same poles as described above. The diaphragm 43 is made of pure steel.

When the same poles of the magnets 42 are disposed opposite to each other, a strong magnetic field is formed in a boundary region facing each other. When a non-ferrous metal (conductor, magnetic body) enters the magnetic field, an eddy current is generated in the non-ferrous metal. The rebound causes the non-ferrous metal to bounce off.

When the partition plates 43 made of pure iron are provided between the same poles of the magnets 42 facing each other, the magnetic flux density (collection speed) increases greatly. As the magnetic flux density increases, the eddy currents generated inside the non-ferrous metal become larger, and when the eddy current increases, the repulsive force further increases, so that the non-ferrous metal bounces more and better. .

The frame wall 50 is installed on the upper surface of the frame 10 and is installed so as to surround the rotation table 30. The upper end of the rim wall 50 is in contact with the bottom surface of the separating work plate 60. The upper edge of the rim wall 50 is positioned higher than the upper end of the magnet assembly 40 so that the separation plate 60 is separated from the magnet assembly 40 by a certain distance.

The separation work plate 60 is horizontally installed on the upper side of the frame 10, and a vortex flow path 61 is formed on the upper surface of the separation work plate 60. One side of the separating work plate 60 is rotatably installed on the frame 10 so that the separating operation plate 60 can be easily rotated when the separating operation is performed and when the separating operation is not performed.

The vortex-type flow path 61 is formed in a vortex flow shape starting from the center of the separation work plate 60 and increasing in width as it goes outward. The vortex flow path 61 is formed with a conductor (non-ferrous metal) (Water) is introduced. In other words, the vortical flow passage 61 has a shape in which the width of the flow passage gradually increases from the center to the outside. Since the width of the vortex-type flow path 61 is gradually widened from the center toward the outer side, when the mixture of the non-ferrous metal and the non-metal and water is supplied at the center of the flow path, the flow rate of the mixture becomes slower toward the outside, will be.

The bottom surface of the vortex channel 61 is inclined such that the vortex channel 61 is higher toward the outer edge, that is, toward the edge of the separating plate 60.

In addition, a backflow prevention tuck 62 protrudes from the bottom surface of the inclined vortex flow path 61. The backflow preventing blade 62 is formed such that the inner surface 62a is smaller in inclination angle with respect to the bottom surface of the vortex flow path 61 than the outer surface 62b. That is, the inner surface of the backflow preventing blade 62 is formed of a smooth curved surface having a gentle slope, and the outer surface is formed of a curved surface or a straight surface having a steep slope.

The mixture providing unit 70 includes a water tank 71, a guide pipe 72 having one end connected to the water tank 71 and guiding the mixture, and a pump 73 installed on the pipe of the guide pipe 72 ).

In the water tank 71, fine particles having a diameter of about 0.5 to 2.0 mm are mixed in water. Dispersions mixed with water are nonconductors and nonconductors such as nonmetals.

The guide pipe 72 is one end immersed in the mixture stored in the water tank 71 and the other end is positioned at the starting point of the vortex flow path 61, that is, above the center portion of the vortex flow path 61. Therefore, the mixture flowing inside the guide pipe 72 falls slightly to the center portion of the vortex flow path 61. Although not shown in the drawing, various valves and the like can be installed in the guide pipe 72 for controlling the outflow of the mixture and the like.

The pump 73 is installed on the conduit of the guide pipe 72 to flow the mixture. By the operation of the pump 73, the mixture moves toward the eddy-current path 61.

The operation of the horizontal rotary type wet eddy current separator according to the present invention will be briefly described below.

The pump 73 is operated to supply the mixture of the non-ferrous metal of the small diameter, the non-metal and the water into the swirling flow path 61 of the separation working plate 60.

At the same time as the mixture is supplied, power is supplied to the motor 20 so that the motor shaft rotates. When the motor shaft of the motor 20 rotates, the rotary table 30 rotates below the separation work plate 60 and the magnet assembly 40 on the upper surface of the rotary table 30 sequentially rotates.

When the magnet assembly 40 rotates as described above, a constant magnetic field is formed around the magnet assembly 40, and at the same time, an eddy current is generated in the non-ferrous metal of the non-ferrous metal and the non-metal. When an eddy current is formed in the non-ferrous metal, the non-ferrous metal tends to be repelled outwardly of the eddy-current flow path 61 by the repulsive force with the magnetic field. However, since the non-ferrous metal is fine particles having a diameter of 2.0 mm or less and is mixed with water, the non-ferrous metal can not be thrown out of the vortex-type flow path 61 but flows outside the vortex flow path 61 beyond the inner surface 62a of the flow- . On the other hand, the base metal in which the eddy current is not generated collects inside the vortex flow path 61.

Then, the non-ferrous metal of the fine particles moved to the outside of the vortex flow path 61 is clogged by the flow-backing prevention tumbler 62 and does not move inward. When the mixture of the non-ferrous metal, the non-metal and the water is continuously supplied from the central portion of the vortex flow path 61 in this state, the initially supplied mixture is pushed out later by the supplied mixture to be supplied to the outside of the vortex flow path 61, 60). As described above, since the non-ferrous metal is gathered outside the vortex flow path 61 and the base metal is gathered inside the vortex flow path 61, the non-ferrous metal and the nonmetal fall off at different places even when the mixture is dropped in the separation working plate 60 . Therefore, it is possible to separate the non-ferrous metal and the non-metal separately from the mixture of the non-ferrous metal and the non-metal.
