At this time, in order to prevent the dust and foreign matter collected in the waste collection box 70 is circulated in the above-described water circulation process, the drain line of the waste collection box 70 is preferably installed higher than the bottom surface, furthermore, the circulation pump 90 may be provided with a removable debris removal filter (not shown) to prevent the circulation pump 90 from being damaged by dust or foreign matter mixed in the circulating water.

On the other hand, the vibration means for vibrating the first diaphragm 50 and the second diaphragm 60 is installed on one side of the frame 100, the excitation means vibrates the frame to the first diaphragm 50 and It is configured to vibrate the second diaphragm 60.

In this embodiment, as an example, the excitation means is a drive motor (M), one end 110b is connected to the frame 100 and the other end (110a) is composed of a rotating shaft 110 connected to the drive motor (M) At one end 110b of the rotating shaft 110 connected to the frame 100, an eccentric portion (not shown) of a predetermined portion is formed.

Therefore, when the rotation shaft 110 is rotated by the drive motor M, the eccentric portion periodically collides with the frame 100 and moves the frame 100 in a predetermined direction (that is, the first diaphragm 50 as described above). The copper wire and the PVC coating in the and the second diaphragm 60, respectively, to vibrate in the direction to be transported in the direction of the second end 50b of the first diaphragm 50), and accordingly fixed to the frame 100 The first diaphragm 50 and the second diaphragm 60 vibrate in the same direction as the frame 100.

In this case, the shape of the connecting portion of the frame 100 connected to the end portion 110b of the rotating shaft formed with the eccentric portion is preferably formed to collide with the eccentric portion so that the frame 100 can be vibrated in a predetermined direction.

In the present embodiment, the case in which the excitation means is configured as described above as an example, but is not limited thereto, and may be preferably implemented by a variety of known excitation means within the scope of performing the same function, of course, if necessary The first and second diaphragms 50 and 60 may be configured to vibrate directly.

In addition, the frame 100 further includes at least one striking device for striking the second diaphragm 60 in order to prevent tangling of foreign matter, etc. in the mesh structure of the second diaphragm 60.

The striking device has a beam shape connected to the first rod 111 and the second rod 112 fixedly installed at both side walls of the frame 100 to support the first diaphragm 50 and the second diaphragm 60. A tapping member 121, a leg 121 screwed in a vertically rotatable direction to the connecting member 120, and a tapping attached to the leg 121 to abut on the second diaphragm 60 by its own weight. It consists of a ball 122.

At this time, in this embodiment, the connection member 120 is configured as a pair of left and right, a plurality of legs 121 and the tamping ball 122 is connected to the left or right of each connection member 120 as an example Although described, the present invention is not limited thereto and may be preferably implemented in various forms.

The striking devices are rotated in the vertical direction as the second diaphragm 60 vibrates and strikes the second diaphragm 60 by its own weight, thereby causing the foreign matter to be caught in the mesh scale of the second diaphragm 60. By dropping the back to the bottom of the waste collection box 70 can prevent the phenomenon that the foreign matter is entangled in the mesh grid and blocked.

In addition, at least one buffer spring S is installed between the first diaphragm 50 and the second diaphragm 60 to mitigate the shock transmitted to the first diaphragm 50 by the vibration of the frame 100. It is.

Waste wire sorting apparatus 1 according to an embodiment of the present invention configured as described above is separated by separating the crushed copper wire and PVC coating while repeating the following operation.

First, when the waste wire is introduced into the rectangular hopper 10, the waste wire is crushed by copper wire and PVC coating by the cutter C of the grinder 20 rotated by the high speed rotary motor 30, The copper wire and the PVC sheath are dropped to the first diaphragm 50 by gravity along with dust and foreign matter.

As described above, the copper wire and the PVC coating dropped to the first diaphragm 50 are first removed of dust and foreign matter by the water sprayed from the water spraying device 40, and the difference in specific gravity between the copper wire and the PVC coating. And are selected by the vibration of the first diaphragm 50, respectively.

That is, the PVC coating having a low specific gravity is conveyed along with water in the direction of the first end 50a, which is a downward inclination direction of the first diaphragm 50, while the high specific gravity copper wire is moved by the first diaphragm 50 by the excitation means. By vibrating movement of the first diaphragm 50 is transferred in the direction of the second end 50b of the upward inclination direction is discharged to the copper wire discharge chute (not shown) provided separately in the frame 100.

At this time, the water spraying device 40 is preferably installed in a plurality of places along the transfer direction of the copper wire in the upper portion of the first diaphragm 50 to remove the fine dust or foreign matter contained in the copper wire to be selected in multiple stages. .

On the other hand, the water, PVC coating, and the like transferred in the direction of the first end 50a of the first diaphragm 50 falls to the end of the second diaphragm 60 along the guide 50c, among which water and The foreign matters are collected through the mesh structure of the second diaphragm 60 and collected in the waste collection box 70, and the PVC coating is filtered through the mesh structure, and then the first vibration plate 60 is vibrated by the second diaphragm 60 as described above. It is conveyed in the direction of the second end (50b) of 50) is discharged to the PVC discharge chute (not shown) provided separately in the frame 100.

At this time, the size of the foreign matter transferred to the second diaphragm 60 is similar to the mesh scale of the second diaphragm 60 or melted by the heat generated during the pulverization, the viscous state does not pass through the mesh scale and the gap of the mesh scale The mesh grid is entangled in to prevent the mesh grid, and in this case, the drainage of the water is not made smoothly, and the transfer of the PVC coating by the vibration is prevented.

Therefore, in order to prevent the waste wire sorting device 1 according to the present invention, as described above, a plurality of separately hitting devices rotate the second diaphragm 60 while moving up and down when the second diaphragm 60 vibrates. By hitting, it is possible to prevent clogging of the mesh due to entanglement of foreign matters, etc. As a result, the drainage of the water and the transfer of the PVC coating are smoothly performed, thereby efficiently selecting the PVC coating.

In addition, the waste wire sorting device 1 according to the present invention is the water collected in the waste collection box 70 provided in the lower portion of the frame 100 by the above-described circulation pump 90 and the circulation piping system (not shown) Since it is repeatedly used for cooling the grinder 20 and collecting, separating, and washing the pulverized waste wire while being circulated, there is an advantage that the overall water consumption of the sorting device 1 can be significantly reduced.
