Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for recycling an electric wire,

The present invention relates to a waste wire recycling apparatus. More specifically, it is a technology for recovering and recycling a synthetic resin forming a coating of a waste wire, and an apparatus for removing an insulating coating layer surrounding the surface of a conductor for the purpose of insulating various kinds of metallic conductors including copper .

The covering layer covering the surface of various wires or communication cables with conductor as a core is made of synthetic resin (polyethylene, polyvinyl chloride, etc.) excellent in insulating property and bending strength and elasticity. In case of high voltage wire, An insulating tape is wound around the surface of the conductor and a synthetic resin coating layer is formed on the tape.

As such, the demand for electric wires and communication cables based on metallic conductors such as copper is increasing, and the disposal amount of the waste wires that are disposed of in various waste electronic devices, waste communication equipment, and demolished buildings is also increasing. The wastewater that is formed is becoming a serious pollution source.

In this way, waste wires such as copper are not only expensive but also have a very wide range of application, which is highly valuable for recycling, and synthetic resin coatings composed of coating layers are also highly available for recycling.

However, in order to recycle such waste wires, it is necessary to effectively separate the conductive metal and the synthetic resin as the covering material, and the cost of collecting the waste wire and the cost of the separation process must be sufficiently covered by the recycled material.

As described above, various means for recycling waste wires are known, and there is also known a method of incinerating synthetic resin, which is a coating agent, in order to collect only metal-made conductors. However, there is a problem that the incineration method of the clone is inconvenient when the synthetic resin covering material is incinerated, there is a problem of dioxin and odor, environmental pollution caused by carbon generation, and a loss of incineration of the recyclable synthetic resin. There is a problem such as change and discoloration.

However, in the prior art 1 described above, since the apparatus is very complicated, the PVC coating layer and the PE covering layer are dissolved by using the coating solution, which requires an expensive solution and a solution to the pollution problem by the solution is a problem , There is a limitation in treating a large amount of waste wires due to the complexity of the apparatus, and the coating layer dissolved by the dissolving liquid is difficult to recycle.

The prior art 2 is a structure in which the PVC skin is brought into a molten state by applying heat at a proper temperature to the waste wire in the heating cylinder accommodating the waste wire, and then the molten PVC skin is collected using the centrifugal force.

In the prior art 2 having such a structure, the structure of the mechanical device is very complicated, and the power loss is very large. When the machine is stopped or the temperature is lowered, the PVC in the molten state is stuck to the inside of the machine, There is a problem that it takes a long time to melt and there is a problem that the efficiency of peeling can not be greatly improved.
