통신 및 전력의 수요가 급증하는 현대에 있어서, 각종의 전신과 케이블의 사용량증대에 따라 폐케이블이나 불량케이블의 양도 엄청나게 증가하고 있으며, 이들의 처리는 심각한 문제를 야기시키고 있다.In modern times, when the demand for communication and electric power is rapidly increasing, the amount of waste cables and defective cables is increasing tremendously with the increase in the use of various telegraphs and cables, and their processing causes serious problems.

폐케이블이나 불량케이블의 처리방법으로는 화력으로 피복을 소각하는 소각분리법, 절단기로 폐케이블을 잘라 분쇄기와 풍압을 이용하여 분리하는 분쇄분리법, 황산 등의 화공용제로 피막을 용해시키는 화공용 탈피방법이 있다.As a treatment method of waste cable or bad cable, incineration separation method to incinerate the cover by thermal power, shredding method to cut the waste cable with a cutter and separate it using a grinder and wind pressure, stripping method for chemical process to dissolve the film with chemical solvents such as sulfuric acid There is this.

그러나, 상기한 바와 같은 종래의 방법에 의하면, 소각분리법에 의할 경우 악취로 인한 대기오염과 내부도체를 이루는 동의 순도가 저하된다는 문제점이 있고, 분쇄분리법에 의할 경우 동과 피복의 분리가 미흡하다는 문제점이 있으며, 화공용 탈피방법에 의할 경우 악취와 공해유발 및 비용이 많이들고 피막재생이 불가능하다는 등의 문제점이 있었다.However, according to the conventional method as described above, the incineration separation method has a problem that the purity of the copper forming the inner conductor and the air pollution due to odor is lowered, and the separation of copper and the coating is insufficient in the crushing separation method. In the case of the chemical stripping method, there are problems such as odor and pollution pollution and cost, and film regeneration is impossible.

특히 폐케이블의 내부도체부를 제거한 피복체를 구성물질별로 분리수거하기 위해서는 오로지 수작업에 의존해 왔기때문에 그 분리가 매우 힘들고 사건과 인건비가 많이 들 뿐만 아니라, 접착제 및 방수역할을 하는 콜타르층때문에 그 분리가 용이하지 않고 분리되더라도 그 분리가 완전하지 못하다는 문제점이 있었다.In particular, the separation and removal of the inner conductor of the waste cable has been made only by manual labor to separate and separate the inner conductor parts of the waste cables. Therefore, the separation is very difficult and the cost of labor and labor is high. There was a problem that the separation is not complete even if not easy to separate.

따라서 본 발명의 목적은 폐케이블의 피복체분리에 있어서 환경오염을 일으키지 않을 뿐만 아니라 재생활용률도 매우 높으며 그 분리가 용이한 피복체의 분리방법 및 그 장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a method and an apparatus for separating a coating, which does not cause environmental pollution in separating the coating of a waste cable, and also has a very high recycling utilization rate, and is easily separated.

상기와 같은 본 발명의 목적을 달성하기 위하여 내부도체와 분리된 피복체를 소정의 길이로 절단하는 절단기와, 상기 절단된 피복체를 냉동시키는 냉동기와, 상기 냉동된 피복체를 분쇄하는 분쇄장치와, 송풍기와 걸름망이 장착되어 종이와 콜타르를 분리하기 위한 진동장치와, 상기 각각의 장치를 연결하는 콘베이어벨트와, 상기 진동장치의 배출구에 연결된 콘베이어밸트의 상부에 자석영역을 갖는 콘베이어를 구비하여 내부도체가 제거된 폐케이블의 피복체를 소정의 길이로 절단하는 제1단계와, 절단된 피복체를 콜타르가 냉동되는 온도에서 소정시간 냉동시키는 제2단계와, 냉동된 피복체를 분쇄하는 제3단계와, 분쇄된 피복체를 진동시킴과 동시에 송풍장치를 작동시켜 피복체의 종이를 분리하고, 진동장치의 하방에 장착된 걸름망에 의하여 콜타르를 분리하는 제4단계와, 종이와 콜타르가 분리된 나머지 피복물질이 이송되는 콘베이어벨트의 상부에 장착된 자석영역을 갖는 콘베이어에 의하여 금속을 분리하는 제5단계가 순차적으로 이루어짐을 특징으로 한다.In order to achieve the object of the present invention as described above, a cutter for cutting the coating body separated from the inner conductor to a predetermined length, a freezer for freezing the cut coating body, a grinding device for grinding the frozen coating body and And a conveyor equipped with a blower and a strainer for separating paper and coal tar, a conveyor belt connecting the respective devices, and a conveyor having a magnet region on the upper portion of the conveyor belt connected to the outlet of the vibrator.

이하 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.

일반적으로 케이블의 내부도체를 감싸는 피복체는 절연을 위한 종이층과, 층사이의 접착 및 방수를 위한 콜타르층과, 금속층과, 폴리에틸렌으로 이루어진 외피로 구성된다. 본발명에서는 종이와 금속층 및 외피를 순도의 저하나 불순물없이 효과적으로 분리수거하고자 한다.In general, the sheath covering the inner conductor of the cable consists of a paper layer for insulation, a coal tar layer for adhesion and waterproofing between the layers, a metal layer, and an outer sheath made of polyethylene. In the present invention, the paper and the metal layer and the outer shell is to be effectively separated and collected without deterioration of purity or impurities.

제1도는 본발명의 전체평면도이고, 제2도는 본 발명의 부분측면도로서, 자석영역을 갓는 콘베이어 및 금속분리수거용 호퍼를 나타낸 것이며, 제3도는 본발명의 냉동기의 내부구조를 보인 참고단면도이다. 상기 제1도 내지 제3도를 참조하여 본발명을 상세히 설명한다.1 is an overall plan view of the present invention, FIG. 2 is a partial side view of the present invention, showing a conveyor and a metal separation hopper filling a magnet region, and FIG. 3 is a reference sectional view showing the internal structure of the refrigerator of the present invention. The present invention will be described in detail with reference to FIGS. 1 to 3.

우선 내부도체와 분리된 피복체를 소정의 절단장치(10)에 의하여 소정의 길이로 절단한다. 그다음 이송장치에 의하여 절단된 피복체를 냉동기(20)로 이송한다. 여기서 상기 냉동기(20)의 온도는 콜타르의 어는점 이하이어야 하며 본발명의 실시예에서는 약 -45℃로 설정하였다. 콘베이어밸트가 상기 냉동기(20)를 통과하는 1분여의 시간동안 피복체내의 콜타르가 냉동되어 이후의 분리작업이 용이하게 된다.First, the coating body separated from the inner conductor is cut into a predetermined length by a predetermined cutting device 10. Then, the coating body cut by the transfer device is transferred to the freezer 20. Wherein the temperature of the refrigerator 20 should be below the freezing point of coal tar and set to about -45 ℃ in the embodiment of the present invention. The coal tar in the coating is frozen for about one minute while the conveyor belt passes through the freezer 20, so that subsequent separation operations are facilitated.

그다음 냉동된 피복체를 분쇄기(30)로 이송하여 분쇄한다. 이때 콜타르가 냉동된 상태이므로 종이와 금속층은 쉽게 분리되어 분쇄된다. 상기 분쇄기(30)에 의해 분쇄된 피복체는 송풍장치(42)가 탑재된 진동장치(40)로 이송된다. 여기서 상기 송풍장치(42)에 의하여 무게가 가벼운 종이는 이송관(44)으로 집진·분리되어 별도의 통에 모아진다. 또한 분쇄된 콜타르는 진동장치(40)의 하방에 안착된 걸름망(도면에 도시되지 않음)에 의해 상기 걸름망의 하부로 걸러진다. 따라서 상기 진동장치(40)내의 걸름망상면에는 종이와 콜타르를 제외한 피복체물질 즉, 금속과 외피만이 남게된다.The frozen coating is then transferred to a grinder 30 and ground. At this time, since coal tar is frozen, the paper and the metal layer are easily separated and crushed. The coating material pulverized by the crusher 30 is transferred to the vibrator 40 on which the blower 42 is mounted. Here, the paper having a light weight by the blower 42 is collected and separated by the transfer pipe 44 and collected in a separate cylinder. In addition, the crushed coal tar is filtered to the lower portion of the strain net by a strain net (not shown) seated below the vibrator 40. Therefore, only the coating material, that is, the metal and the shell, except the paper and coal tar, remain on the trapping mesh surface in the vibrator 40.

그다음 상기 금속과 외피를 콘배이어밸트로 이송한다. 여기서 상기 이송콘베이어벨트(1)의 상부에 자석영역을 갖는 콘베이어(50)를 장착하여, 이송과 동시에 자석(52)에 의하여 금속을 분리한다. 즉, 적어도 이송콘베이어벨트(1)의 폭만큼의 길이와 소정폭을 갖는 자석영역을 갖는 콘베이어(50)를 이송콘베이어밸트(1)의 상부에 고정시켜 상기 이송콘베이어상면의 금속을 분리하고, 분리된 금속은 자석영역을 갖는 콘베이어(50)에 의해 이송되다가 자석이 끝나는 지점에 인접하여 장착된 호퍼(54)에 의해 별도의 콘베이어밸트(56)위로 안내된다. 상기와 같이 하여 분리된 금속은 압축장치(도면에 도시되지 않음)로 압축시켜 재활용된다. 여기서 상기 자석영역을 갖는 콘베이어의 표면에, 금속이 호퍼내로 이동할 때 상기 콘베이어의 회전력에 의해 금속이 바깥으로 이탈되는 것을 방지하기 위한 돌출편(58)을 형성할 수도 있다.The metal and the shell are then transferred to a cone battery belt. Here, the conveyor 50 having a magnet region is mounted on the transfer conveyor belt 1 to separate the metal by the magnet 52 at the same time as the transfer. That is, the conveyor 50 having a magnet region having a length and a width equal to at least the width of the conveying conveyor belt 1 is fixed to the upper portion of the conveying conveyor belt 1 to separate and separate the metal on the upper surface of the conveying conveyor belt. The metal is transported by a conveyor 50 having a magnet region and then guided onto a separate conveyor belt 56 by a hopper 54 mounted adjacent to the end of the magnet. The metal separated as described above is compressed by a compression device (not shown) and recycled. In this case, a protrusion piece 58 may be formed on the surface of the conveyor having the magnet region to prevent the metal from being separated out by the rotational force of the conveyor when the metal moves into the hopper.

한편 이송콘베이어벨트(1)상에 남아있는 외피는 별도의 통에 모아져 재활용된다.Meanwhile, the outer shell remaining on the conveying conveyor belt 1 is collected and recycled in a separate container.

상술한 바와같이 본 발명은 폐케이블의 피복체를 구성물질별로 분리함에 있어서, 종래의 수작업으로 진행해 오던 것을 기계작업으로 대체함으로써 인건비를 대폭 절감할 수 있는 효과가 있다. 또한 절단과 분쇄과정 사이에 냉동과정을 거침으로써 콜타르를 냉동시켜 피복체를 구성하는 막의 분리가 용이하게 이루어지며, 진동장치와 자석영역을 갖는 콘베이어의 하부를 통과하는 동안 종이와 금속 및 외피가 완전히 분리됨으로써 환경에 어떠한 문제도 야기시키지 않고 각각의 물질을 완전하게 분리할 수 있을 뿐만 아나라, 분리된 각 물질을 재활용할 수 있어 자원절약면에서도 우수한 효과를 얻을 수 있다.As described above, the present invention has the effect of drastically reducing labor costs by separating the covering of the waste cable for each component by replacing the conventional manual work with the mechanical work. In addition, the freezing process between the cutting and crushing process to freeze the coal tar to facilitate the separation of the film constituting the coating, and to completely pass the paper, metal, and shell while passing through the lower part of the conveyor having a vibrator and magnet area. By separating, not only can each material be completely separated without causing any problems to the environment, but also each material can be recycled to obtain excellent effects in terms of resource saving.
