본 발명은 오래된 전선이나 폐기된 전기줄(일종의 폐품)을 수집하여 전선의 주구성원인 표면의 폴리비닐클로라이드 수지(이하, PVC)와 전선 내부의 동을 분리하여 PVC는 PVC대로, 동은 동대로 자원화하기 위한 폐전선의 PVC와 동의 분리방법에 관한 것이다.The present invention collects old wires or discarded electric wires (a kind of scrap) and separates polyvinyl chloride resin (PVC) on the surface, which is the main member of the wires, and copper inside the wires, so that PVC is recycled as PVC and copper is used as copper. The present invention relates to a method of separating PVC and copper from waste wires.

종래의 폐전선 분리방법은 전선을 한줄 한줄 기계로 가르는 방법과 분쇄기로 분쇄하는 방법, 불로 태우는 방법 등이 있으나, 능률이 낮고 분리된 PVC에 불순물이 포함되거나 동이 손상되며, 또한 공해를 일으키는 문제점이 있었다.Conventional methods for separating waste wires include dividing the wires with a single line machine, crushing them with a shredder, and burning them with fire. However, low efficiency and separation of PVC contain impurities or damage copper, and also cause pollution. there was.

따라서 본 발명의 목적은 PVC와 동으로 이루어진 폐전선을 한번에 다량으로 처리하여, PVC와 동에 손상을 주지 않으면서 능률적으로 PVC와 동을 분리하므로써 폐전선을 효율적으로 자원화할 수 있고, 동시에 잔류 폐품이 없어 공해방지에 기여할 수 있는 폐전선 분리방법을 제공하는 것이다.Therefore, an object of the present invention is to efficiently recycle the PVC and copper without damaging the PVC and copper by treating a large amount of waste wire made of PVC and copper at once, and efficiently recycle the waste wire and at the same time It is to provide a method for separating waste wires that can contribute to pollution prevention.

본 발명에 따른 폐전선 분리방법은 PVC와 동으로 이루어진 폐전선을 150~300℃의 온도로 가열된 전기절연유(Transformer Oil : 이하, OT라 한다)에 20분~1시간 동안 완전히 담군 후에 폐전선에 충격을 가하여, PVC와 동을 효율적으로 분리하는 것을 특징으로 한다.The waste wire separation method according to the present invention is a waste wire after completely immersing the waste wire made of PVC and copper in electric insulating oil (Transformer Oil: OT) heated to a temperature of 150 ~ 300 ℃ for 20 minutes ~ 1 hour. It is characterized in that the impact is applied to the PVC and copper efficiently separated.

본 발명에서 사용되는 OT는 석유정제공정에서 나오는 전기절연유로서 DOP유를 포함하는 PVC를 용해하는데 매우 유용하다. 즉, PVC는 염화비닐수지와 DOP유(Dioctyl Phthalate)를 150℃ 이상의 온도로 가열하여 제조되며, DOP유와 OT는 동종류의 기름이기 때문에 상호 융화가 가능하여, DOP유로 구성된 PVC에 OT를 첨가하여 온도를 상승시키게 되면 PVC중에 함유된 DOP유와 OT의 상호작용에 의하여 PVC가 연질화된다.OT used in the present invention is very useful for dissolving PVC including DOP oil as the electric insulating oil from the petroleum refining process. In other words, PVC is manufactured by heating vinyl chloride resin and DOP oil (Dioctyl Phthalate) to a temperature above 150 ° C. Since DOP oil and OT are the same kind of oils, they are mutually compatible, and OT is added to the PVC composed of DOP oil. When the temperature is increased, PVC softens due to the interaction between OT and DOP oil contained in PVC.

본 발명에서는 상기와 같은 원리에 의해, PVC와 동으로 이루어진 폐전선에 높은 온도로 가열된 OT를 첨가하면, 폐전선의 외피를 구성하는 PVC가 연질화되며, 이런 상태에서 폐전선에 약간의 충격을 가하면 연질화된 PVC와 동이 아주 용이하게 분리된다.In the present invention, by adding the OT heated at a high temperature to the waste wire made of PVC and copper, the PVC constituting the shell of the waste wire is softened, and in this state, a slight impact on the waste wire. When it is added, the softened PVC and copper are very easily separated.

본 발명에서 폐전선을 가열된 OT에 담군 후에 충격을 가하는 방법으로는 어떠한 방법도 가능하나, 예로서 세탁기 탈수 방법과 같은 회전력에 의한 충격방법을 들 수 있다. 즉, 폐전선을 가열된 OT에 충분히 담구어 폐전선의 외피인 PVC를 연질화한 후, OT를 제거한 상태(탈유충격분리방법) 또는 OT를 제거하지 않은 상태(비탈유충격분리방법)에서 회전력에 의한 충격을 가하므로써 PVC와 동을 분리시킨다.In the present invention, any method may be used as a method of applying a shock after immersing the waste wire in the heated OT, but an example may be an impact method using a rotating force such as a washing machine dewatering method. That is, after sufficiently immersing the waste wire in the heated OT to soften the PVC, which is the outer skin of the waste wire, the rotational force in the state where the OT is removed (desulfurization impact separation method) or OT is not removed (the non-soil impact impact method) PVC and copper are separated by impact.

이하, 첨부도면을 참조하여 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도에 도시된 바와 같은 장치를 이용한 탈유충격분리방법에 의한 폐전선의 PVC와 동의 분리방법은 다음과 같다.The separation method of PVC and copper of the waste wire by the deoiling impact separation method using the apparatus as shown in FIG. 1 is as follows.

탈수기형의 회전가능한 탈유통(m)에 폐전선출입구(c)를 통해 폐전선(h)을 넣고, 별도의 통에서 버너(j)와 같은 가열수단에 의하여 150~300℃의 온도로 가열된 OT(f)를 OT입출장치(d)를 이용하여 탈유통(m)으로 투입한다. 폐전선이 가열된 OT에 담구어진 상태로 30분~1시간 경과후, OT(f)를 탈유구(l)을 통해 제거한 다음 탈유통(m)을 회전시켜, 연질화된 PVC와 동을 분리한다. 이때 제거된 OT와 분리된 PVC 및 동은 모두 재활용될 수 있다.The waste wire (h) is put into the dehydrator-type rotatable de-oiler (m) through the waste wire entrance (c), and is heated to a temperature of 150 to 300 ° C. by a heating means such as a burner (j) in a separate container. The OT (f) is fed into the de-oiler m using the OT draw-out device d. After 30 minutes to 1 hour while the waste wire is immersed in the heated OT, OT (f) is removed through the draining port (l), and then the deflowing tank (m) is rotated to separate the softened PVC and copper. do. At this time, both the removed OT and the separated PVC and copper can be recycled.

제2도에 도시된 바와 같은 장치를 이용한 비탈유충격분리방법에 의한 폐전선의 PVC와 동의 분리방법을 설명하면, 하나의 통에 폐전선(h)과 OT(f)를 함께 넣고, 버너(j)와 같은 가열수단을 이용하여 가열한 후, 폐전선과 OT가 혼합된 상태에서 회전수단을 이용해 회전시키므로써 PVC와 동을 분리한다. OT는 회전처리후 OT배출구(n)를 통해 제거할 수 있다.Referring to the method of separating the PVC and copper of the waste wire by the non-depolarizing impact separation method using a device as shown in Figure 2, put the waste wire (h) and OT (f) in one tube together, burner ( After heating by using a heating means such as j), by separating the PVC and copper by rotating by using a rotating means in a state in which the waste wire and the OT is mixed. OT can be removed through the OT outlet (n) after the rotation process.

이상과 같이 본 발명에서는 OT의 사용과 온도 및 충격방법을 조합하여 적용하므로써 아주 용이하게, 또한 매우 효율적으로 폐전선의 PVC와 동을 분리할 수가 있다.As described above, in the present invention, by using a combination of the use of the OT, the temperature and the impact method, PVC and copper of the waste wire can be separated very easily and very efficiently.
