Description

Wood Plastic Combination manufacturing system using ruined correspondent cable

The present invention is an artificial wood using a waste communication cable to efficiently separate the ash, such as copper by using a waste communication cable, and to produce artificial wood (WPC, Wood Plastic Combination) using a synthetic resin cladding of waste communication cable It is about the system.

Wires for powering factories or homes or for telecommunications, such as telephones, consist of metal wires and sheaths for insulation and wire protection.

Copper, aluminum, or alloys thereof are mainly used as metal wires, and polyethylene (P.E.), polypropylene (P.P.), and polyvinyl chloride (P.V.C.) are mainly used as coating materials.

Electric wires are used with various thicknesses, number of strands, and covering structures depending on the purpose of use. For example, in the case of a cable used for communication, in particular, a communication cable as an underground cable embedded underground, jelly wires filled with jelly, which is a polyester slime, are used in a coating material.

As described above, the jelly filled in the coating material is composed of a highly viscous material, and the jelly is distributed around the chest thin wire to protect the thin metal wire, to make it waterproof, and to prevent damage to the thin wire by rats and ants. It can be effective.

Generally, since the waste wire contains expensive metal resources, the metal is recycled by separating the cover material and the metal wire in various ways.

In regenerating the waste wire, a stripping machine is used to strip the coating material to recover the copper, or to recover the copper by incineration of the coating material. In addition, fine wires, such as communication lines, which cannot be used in the stripping machine, separate and recover copper through a chipping machine.

The method of recovering copper through incineration has a problem that the quality of the copper wire is degraded due to oxidation of copper wires, and that a fatal harmful gas is generated when the resin such as the coating material is incinerated.

The chapping process has been proposed through the Republic of Korea Patent Publication No. 10-2000-311, Republic of Korea Patent Publication No. 10-2002-70408 and Japanese Patent Publication No. JP2001-283661.

However, it is impossible to regenerate the waste wire including jelly by the method by the chipping. In the case of a communication cable containing jelly, the covering material can be removed through the incision, but the grinding is difficult due to the adhesive force of the high viscosity jelly during the chapping process.

Therefore, in the case of a jelly wire such as a communication cable, there is a problem that it is very difficult to separate and recover the copper wire through the chapping.

Due to these problems, recently, a technique of dissolving and removing jelly using chemicals (volatile solvents) and then separating copper and coating materials using a chipping machine has been proposed. However, this method uses a volatile solvent, so there is a high risk of explosion.

The present invention has been made to solve the above problems, when recycling the waste communication cable to remove the jelly in the communication cable dry dry without using a volatile solvent to effectively separate the copper and synthetic resin coating material, recovered copper It is an object of the present invention to provide an artificial wood manufacturing system using a waste communication cable that can be recycled, and the recovered synthetic resin coating material can continuously produce artificial wood (WPC).
