BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separation device for a waste wire and a useful resource recovery system for a waste wire including the same,

The present invention relates to an apparatus for separating a waste wire for the recycling of a waste wire including an optical cable and a useful resource recovery system for the waste wire including the waste cable. More specifically, The present invention relates to a device for effectively separating metallic cables, optical fibers, and the like of wires from each other by materials and a useful resource recovery system for the waste wires including the same.

The optical cable is a cable for converting an electric signal into a light signal and transmitting the signal through the glass fiber. The cable may be composed of a core, an inner covering material and an outer covering material from the center to the outer side.

The shim is an optical fiber made of very thin glass or plastic. The main component is silicon dioxide (SiO ₂ ), and a small amount of germanium (Ge) is added thereto. In order to protect the shim, a metal tube layer is used as an inner covering material.

In addition, an outer cover material of a polymer resin material is formed on the outer surface of the inner cover material to cover the inner cover material and to prevent moisture from being blocked on the outer surface of the inner cover material by using an adhesive.

One such optical cable has a transmission speed of up to 2.5 Gbps when using one wavelength, and it can increase transmission speed by transmitting several wavelengths at the same time. In addition, it is possible to transfer a large amount of data, and a large space can be installed in a narrow space.

The demand for the optical cable has been explosively increased with the development of domestic communication networks, and it is increasingly necessary to transmit a large amount of data quickly according to the composition of an apartment or an industrial complex.

On the other hand, in the case of remodeling or expanding existing buildings, existing optical cables are removed, and in the case of using more advanced optical cables, waste wires are generated. Since there is no apparatus for collectively recycling the waste wires, . In addition, recently, China has also banned the import of waste wires, which is a burden on the related industries.

At present, the recycling rate of the waste wire is about 30%, and there is a high need for environmentally friendly recycling equipment that can raise the recycling rate to 90% or more.

In this connection, Japanese Unexamined Patent Publication (Kokai) No. 2000-228054 discloses a linearizing means for straightening bent or bent portions of an optical cable and forwarding the bent portions. A cutting means for cutting the outer surface of the optical cable supplied from the linearizing means; A high-frequency induction heating means for inducing high-frequency induction heating of the optical cable whose sheath is cut by the incision means to soften the sheath; And a peeling means for peeling off the sheath so that the outer surface of the optical cable heated by the high frequency induction heating means can be separated from the inner surface of the optical fiber.

Patent Document 1 discloses a method of separating and recovering the inner skin and the outer skin of an optical cable, but fails to disclose a method of recovering the optical fiber.

In Patent Document 2, the optical cable is heated by the induction coil member to soften the outer skin by the rise of the core temperature and separate from the core, and the core is cut into a certain size without crushing the core.

Patent Literature 3 discloses a method in which the discarded optical cable is crushed and pulverized, heat is applied, impact is applied, the filter is applied, the impact is applied again, hot air is applied, Disclosed is an automatic recycling apparatus which can be recycled separately.

The apparatus of Patent Document 3 starts with the process of crushing the optical cable with the debris first and crushing with the crusher. Since the different materials are completely mixed with each other, it is necessary to heat them in order to separate them effectively, Lt; / RTI >

Patent Literature 4 discloses an optical fiber bundle including a plurality of optical fiber bundles and a plurality of optical fiber bundles enclosing the bundle of optical fibers, the bundle including an inner skin made of iron or aluminum and an outer skin made of a synthetic resin material so as to surround the inner skin, To an endothelium enclosed by an endoscope.

In the abandoned light cable separating system of Patent Document 4, the optical cable is cut, vibration and heat are applied thereto to separate the outer skin from the inner skin, the cut optical cable separated from the outer skin is put into a water tank and the outer skin and the inner skin are separated by specific gravity The separated outer shell and inner shell are dried and discharged, and the discharged inner shell is separated into an inner skin of aluminum material or an inner skin of iron material, respectively.

That is, Patent Document 4 includes processes such as a specific gravity separator, a drying unit, and hot air blowing to separate the material of the abandoned light cable.

Thus, although the inventions described in the above-mentioned patent documents disclose a technique for recycling a used wire, it is pointed out that a process design and a cost problem including devices having various functions are pointed out as disadvantages, There is a problem that the recycling rate is low because the adhesive layer and the like are not collected.

Therefore, in order to recycle the waste wire components by separating and collecting the components of the waste wire, there is a high need for an environmentally friendly method that can be applied to various wires having various diameters, and a separation technique with high recycling rate.

The apparatus for separating a used wire according to the present invention comprises a rolling roller for pressing and pressing a waste wire, a cutting part for covering the envelope and the inner skin of the pressurized wire, inducing separation of the outer and inner skin of the cut wire, And a crushing member for finely crushing the inner surface of the waste wire separated by the cutting portion.

The waste wire is positioned on an optical fiber layer made of optical fibers and has an outer surface made of a metal tube. An adhesive layer is disposed on an outer surface of the inner surface, and a sheath made of a polymer material positioned on the outermost surface .

In view of the fact that a polymer resin having a predetermined elasticity is used as an outer sheath of a waste wire, in order to improve the cutting force by compressing the outer sheath, the separation device for the waste wire has a rolling roller . Further, the cutting portion may be a structure added to the rolling roller, or may be located adjacent to the rolling roller, in order to perform cutting in a state where the waste wire is compressed.

Generally, an adhesive layer is disposed between the polymer tube layer, which is the sheath of the waste wire, and the metal tube layer, which is an endotheque surrounding the optical fiber, and it is difficult to separate the polymer tube layer and the metal tube layer by the adhesive layer. After covering the polymer tube layer, the adhesive layer and the metal tube layer of the waste wire, a cut wire cut between the projecting rollers is passed in order to easily separate the polymer tube layer from the metal tube layer.

The waste wire cut by the protruding rollers is moved to the next step so that the cut surface is expanded to separate the metal tube layer from the adhesive layer and the polymer tube layer.

Wherein the protruding rollers are constituted by a pair of rollers located on both sides with respect to the movement direction of the pulsed wire, and the pulsed electric wire moves between the protruding rollers, whereby the mechanical coupling between the envelope and the inner skin So that they are easily separated from each other.

The inner wall of the waste wire thus separated is a rigid metal tube layer, and the outer wall is made of an elastic polymer material. When the inner wall and the outer wall of the wall wire pass through the crushing member, the outer wall of the elastic poly- But the inner skin of the metal tube layer having a low ductility is broken into metal pieces by the crushing member and collected.

The rolling roller may consist of an upper roller and a lower roller, and may have a structure capable of adjusting a gap between the upper roller and the lower roller.

The distance between the upper roller and the lower roller is adjusted by adjusting the outer diameter of the waste wire in a state where the positions of the upper roller and the lower roller are fixed, And it is preferable that the fixed state is maintained after the interval is adjusted as described above.

The outer diameter of the waste wire is reduced while being pressed against the rolling roller, for example, it can be reduced by 10% to 20% with respect to the outer diameter of the circular state, and is preferably reduced by 15% have.

When the reduction rate of the outer diameter of the waste wire is less than 10%, it is difficult to achieve the purpose of improving the cutting force, and when it is more than 20%, it may be an obstacle to the movement of the waste wire.

In one specific example, the cutting portion may have a structure including a pair of cutting members positioned symmetrically with respect to the closed wire at a predetermined angle.

That is, the cutting member may be structured to be separated from the rolling roller, and may be structured so as to be inclined at the same angle from each other in the up-and-down direction opposite to the closed wire.

And a cut end of the cutting member may extend to the inner surface of the closed wire so that cutting is performed to the center of the closed wire. Therefore, at least the inner surface of the waste wire except for the optical fiber layer can be cut.

In another specific example, the cutting portion may have a structure in which a blade protrudes from the outer surface of the rolling surface of the rolling roller.

That is, when the cutting portion having such a structure is formed, the cutting member added with a structure separating from the rolling roller is not applied, and the cutting of the waste wire can be performed simultaneously in the pressure rolling step of the rolling roller.

In addition, if the cutting portion in which the blade protrudes is detachable with respect to the rolling roller, the cutting portion can be easily replaced even if the cutting portion is worn.

The protruding roller breaks the waste wire into three strands. Specifically, the stranded wire splits into two strands of an outer skin, an adhesive layer and an inner skin, and one strand of the optical fiber layer, and moves to the next step.

A plurality of protrusions are formed on the rolling surface of the protruding roller. The size and shape of the protrusions are not particularly limited. For example, a plurality of protrusions having a triangular or quadrangular shape in the vertical cross section may be formed .

The protruding roller is constituted by a pair of rollers located on the left and right sides respectively with respect to the closed wire, and the size and shape of the protrusions can be structured such that they engage with each other when the protruding rollers face each other.

The shredding member may have a structure in which a plurality of pairs of rollers positioned so as to be engaged with each other in the up-and-down direction are continuously positioned, and the rollers may be gear-type rollers.

The gear type roller has a structure in which a pair of rollers in a shape corresponding to each other are engaged with each other, and a pair of gear type rollers may have a structure in which unit rollers of the same shape are combined, The unit rollers may be combined with each other.

Since the outer shell of the polymer material is not easily broken by elasticity, it passes through the crushing member in a stretched state, and the inner skin of the metal material is weakly ductile and can be cut, so that it is broken into pieces of metal particle while passing through the crushing member.

The present invention provides a useful resource recovery system for a used wire including the apparatus for separating a used wire, more specifically, a seating portion having a size corresponding to the outer diameter of the used wire, A cutter for covering the envelope and the inner skin of the pressurized pulsed wire, and a guide for guiding the separation of the outer and inner skin of the cut pulmonary wire A protruding roller, a first crushing member for finely separating the inner wall of the waste wire separated by the cutting unit, a first water rejecting unit for collecting the metal particles crushed by the crushing member, a waste water line passing through the crushing member, A second crushing member for crushing the outer surface of the waste wire crushed by the second crushing member, and a second crushing member for collecting the crust of the crushed waste wire by the second crushing member.

Since the guide roller is formed in the rolling surface with a groove having a size corresponding to the outer diameter of the waste wire, the waste wire is structured to be seated in the groove, Less.

The outer diameter of the waste wire can be variously formed according to the applied environment. In order to flexibly apply to the waste wires of various sizes, the guide roller is composed of an upper roller and a lower roller, It may be a structure capable of adjusting the distance between the rollers.

The upper roller and the lower roller may be moved up and down to adjust the gap between the upper roller and the lower roller or an elastic member may be applied to the connection of the upper roller and the lower roller, The spacing between the lower rollers can be controlled by an elastic material. That is, the elastic member may be shrunk or elongated according to the thickness of the waste wire positioned between the upper roller and the lower roller, so that it can be applied to the waste wire of various thicknesses.
