본 발명은 절연 젤리가 충진된 케이블의 세척분리방법에 관한 것이며 보다 구체적으로는 폐기되는 통신케이블 및 광케이블 내부에 절연을 목적으로 충진된 절연 젤리(폴리부텐)를 세척제로 분리하고, 수지와 구리소재를 분리하여 자원소재로 상품화하고, 절연 젤리와 세척제는 증류방식으로 분리할 수 있도록 한 것이다.The present invention relates to a method for washing and separating a cable filled with insulating jelly, and more specifically, to separate the insulating jelly (polybutene) filled for the purpose of insulation in a discarded communication cable and an optical cable with a cleaning agent, and a resin and a copper material. Is commercialized as a resource material, and the insulating jelly and detergent are to be separated by distillation.

절연 젤리 통신케이블 또는 광케이블은 대체적으로 구경 0.4 ~ 0.9㎜의 구리 심선을 연질 수지로 코팅하고, 이를 50 ~ 100p(2가닥이 1p임)를 수지테이프로 권취하고, 이를 25 ~ 2,400개를 하나의 수지재 케이블로 구성할 때 수분과 습기의 침투를 차단하고, 절연도를 높이기 위하여 절연 젤리로 사용하는 점도가 17 ~ 25인 폴리부텐(Poly Butene, C₄올레핀 중합물이고 합성탄화수소의 일종임)을 충진하여 제조되며 관로 및 직매용으로 사용되는 폼 스킨 젤리 파일링 케이블(foam skin jelly filing cable)과, 정보통신의 테이터 전송에 사용하는 폼 스킨 젤리 파일링 랩 케이블(foam skin jelly filing Lap cable)과, 랜(LAN) 가입자망 장거리 전송시스템에 주로 사용되는 젤리 충진형 광케이블이 알려지고 있다.Insulated jelly communication cable or optical cable is generally coated with a copper core wire of 0.4 to 0.9 mm in diameter with a soft resin, and wound 50 to 100 p (two strands of 1 p) with resin tape, and 25 to 2,400 pieces of one Filled with polybutene (Poly Butene, a kind of synthetic hydrocarbon and a kind of synthetic hydrocarbon) with a viscosity of 17 to 25, which is used as an insulating jelly to block the penetration of moisture and moisture and to increase the insulation when constructing a resin cable. Foam skin jelly filing cable, which is manufactured for pipeline and direct sales, foam skin jelly filing lap cable for data transmission of telecommunications, LAN LAN) Jelly-filled fiber optic cable, which is mainly used for long-distance transmission system, is known.

절개 공정을 거친 케이블을 10 ~ 20㎜의 규격으로 절단되면 길이가 짧고, 외피와 알미늄 테이프의 분리와, 테이프 속에 있는 심선이 외피에서 분리가 용이하여 세척공정을 자동화할 수 있는 규격의 칩(Chip)이 된다.If the cable that has been cut is cut to the size of 10 ~ 20㎜, the length is short, and the size of chip that can automate the cleaning process by separating the outer skin and aluminum tape and easily removing the core wire from the outer skin. )

3. 제3공정(1차 세척공정)3. 3rd process (1st washing process)

원주면에 날개 또는 스크류가 구비한 횡축이 설치된 세척조에서 횡축을 60 ~ 90rpm으로 회전되도록 하고, 세척조내에 세척제(테트라 클로로 에틸렌 또는 트리 클로로 에틸렌)를 투입한 1차 세척조에 제2공정의 절단된 케이블의 칩을 투입시켜 세척한다.Cable cut in the second process to the first washing tank in which the horizontal axis is rotated at 60 to 90 rpm in a washing tank equipped with a wing or screw on the circumferential surface and a washing agent (tetrachloroethylene or trichloroethylene) is added to the washing tank. Put the chips in and wash them.

동 세척공정에는 횡축이 회전되면서 케이블의 칩이 교반 되어 칩에 붙은 절연 젤리(폴리부텐)는 세척제에 용해된다.In the same washing process, the horizontal axis is rotated, and the chip of the cable is stirred, and the insulating jelly (polybutene) attached to the chip is dissolved in the cleaning agent.

제3공정을 거치게 되면 케이블은 연질수지가 코팅된 구리선은 10 ~ 20㎜의 규격으로 분리되고, 광섬유, 비닐, PET, PE수지가 피복된 알미늄 박판지 등이 혼합된 상태가 된다.After the third process, the cable is separated into a soft resin-coated copper wire with a size of 10 to 20 mm, and the aluminum thin paper coated with optical fiber, vinyl, PET, and PE resin is mixed.

4. 제4-1공정(2차 세척공정)4. Step 4-1 (Second Cleaning Process)

제3공정을 거친 케이블은 물이 함유된 2차 세척조에 투입하고, 세척제(테트라 클로로 에틸렌 또는 트리 클로로 에틸렌)를 넣고, 2차 세척공정을 수행하게 된다.After the third step, the cable is put in a secondary washing tank containing water, a washing agent (tetrachloroethylene or trichloroethylene) is added, and the secondary washing process is performed.

한편 투입된 케이블의 칩에서 비중이 낮은 광섬유, 비닐, PET, PE는 수지가 피복된 알미늄 박판지는 부상되고, 비중이 높은 수지가 피복된 구리선, 강선, 수지가 제거된 알미늄 박판지는 침전된다.On the other hand, low-density optical fibers, vinyl, PET, and PE are coated with resin-coated aluminum thin-film paper, and high-density resin-coated copper wire, steel wire, and aluminum thin-film paper are removed.

5. 제4-2공정(2차 세척공정에서 침전물의 분리공정)5. Step 4-2 (Separation of Sediment from Secondary Washing Process)

제4-1공정에서 세척제에 침전된 수지가 피복된 구리선, 강선, 수지가 제거된 알미늄 박판지는 스크류 콘베이어 등으로 인출하여 고압공기로 탈수건조하고, 진동분리기에서 알미늄 판지를 회수하고, 자력분리기에서 강선을 회수하고, 수지가 피복된 구리선도 피복수지를 분쇄하고, 원심 분리 장치에서 피복된 수지재와 구리를 소재별로 분리하여 자원소재로 상품화하게 된다.Resin coated copper wire, steel wire and resin-free aluminum thin film deposited in step 4-1 are taken out with a screw conveyor, dehydrated and dried in high pressure air, aluminum plate is recovered in a vibration separator, and in a magnetic separator. The steel wire is recovered, the copper wire coated with resin is also pulverized with the coated resin, and the coated resin material and copper are separated by material in a centrifugal separator and commercialized as a resource material.

6. 제4-3공정(2차 세척공정에서 6. Step 4-3 (In the Second Cleaning Process 부상물의Wounded 분리공정) Separation process)

제4-1공정에서 물 위로 부상되는 광섬유, 비닐, PET는 수거하여 폐기하고, PE수지가 피복된 알미늄 박판지 등은 고압공기통로를 통과시켜서 탈수 건조시키고 자원소재로 상품화한다.Optical fiber, vinyl and PET that float on water are collected and discarded in step 4-1. Aluminum foil coated with PE resin is dehydrated and dried through high pressure air passage and commercialized as resource material.

7. 제7공정(세척제와 절연 젤리의 분리공정)7. 7th process (separation process of detergent and insulating jelly)

제1세척조와 제2세척조에서 세척제에 절연 젤리(폴리부텐)의 함유량이 증가 되면 세척능력이 저하되므로 세척조에서 인출하여 열매체 보일러를 이용하여 가열하게 되면 세척액은 87.2 ~ 121.6℃에서 증류되므로 이를 증류시켜 이동시킨 다음, 부동액으로 냉각시켜서 세척제 재생 저장시설에 유입시키고, 열에 증류되지 않는 절연 젤리(폴리부텐)는 화학적으로 열에 안정되므로 이를 드럼에 담아서 밀봉하여 절연 젤리(폴리부텐) 제조시설로 이전하여 재생자원 소재로 상품화하거나 또는 폐기물전문처리업체에 이전처리한다.When the content of insulating jelly (polybutene) is increased in the washing tank in the first washing tank and the second washing tank, the washing ability decreases, so when it is withdrawn from the washing tank and heated using a heating medium boiler, the washing liquid is distilled at 87.2 ~ 121.6 ℃, After moving, it is cooled with an antifreeze and introduced into a detergent regeneration storage facility. The insulating jelly (polybutene), which is not distilled by heat, is chemically heat stable, so it is sealed in a drum and transferred to the insulating jelly (polybutene) manufacturing facility for regeneration. Merchandise as a resource material or transfer to a specialized waste disposal company.

한편 세척제은 화학적으로 안정하고, 비가연성이고, 가열시 휘발성이 높고, 비등점이 87.2 ~ 121.6℃(P.C.E는 121.6℃, T.C.E는 87.2℃)이므로 가열 증류시 회수율이 높게 된다.On the other hand, the cleaning agent is chemically stable, non-flammable, has high volatility upon heating, and has a boiling point of 87.2 to 121.6 ° C (121.6 ° C for P.C.E and 87.2 ° C for T.C.E), so that the recovery rate is high during heat distillation.

상기와 같은 본 발명의 제6공정에서 고압공기 송풍 통로의 통과시에는 송풍온도를 50 ~ 70℃의 열풍으로 건조하게 되면 탈수와 동시에 건조가 이루어지고 경제성이 높게 된다.When passing through the high-pressure air blowing passage in the sixth step of the present invention as described above, if the blowing temperature is dried by hot air of 50 ~ 70 ℃ drying is made at the same time as the dehydration and economical efficiency is high.

또 상기 제5공정에서 진동선별공정은 연질수지가 피복된 구리선, AL판지, 강선 등은 진동으로 AL판지를 선별하게 된다.In the fifth step, the vibration screening process is to select the AL paperboard by vibrating the soft resin-coated copper wire, AL paperboard, steel wire and the like.

또 상기 제6공정에서 자력선별공정은 연질수지가 피복된 구리선은 자력이 없어 통과되고 강선은 자력에 흡착되어 선별이 이루어지게 되므로 강선의 회수율이 높게 된다.In the sixth step, the magnetic force selection process is performed because the copper wire coated with the soft resin has no magnetic force, and the steel wire is absorbed by the magnetic force, so that the selection is made.

또 제6공정에서 분쇄공정으로 유입된 칩은 연질수지가 피복된 구리선만 잔존되므로 이는 분쇄공정에서 연질수지를 분쇄시킨 다음 송풍기에서 원심분리공정으로 이송된다.In addition, since the chip introduced into the grinding process in step 6 remains only the copper wire coated with the soft resin, it is pulverized in the grinding process and then transferred from the blower to the centrifugation process.

상기 제6공정에서 원심분리공정에는 비중이 높은 구리선과, 비중이 낮은 수지재를 선별하여 상품화하게 된다.In the sixth step, the centrifugation step selects and commercializes a high specific gravity copper wire and a low specific gravity resin material.
