The fibrous material collected in the aforementioned fibrous collecting container 14 may be put into the extruder 16 and extruded into the chip 17 by heat of 200 to 250 ° C., and then mainly used as a material for forming a packet or a water pipe.
실시예 - 이상의 공법에 의한 한 실시예를 설명하면 다음과 같다.EXAMPLES An example by the above construction method is demonstrated.
자동차용 폐 메트 100㎏를 절단기(1)에 투입하여 약 10∼20㎝길이로 절단된 것을 콤베어(2)를 통해 1차분쇄기(3)에 투입하여 이의 길이가 약 10㎜정도 되게 조분쇄한바 섬유질성분을 가진 폴리에스텔과 고형 성분을 가진 PVC 입자가 혼합된 혼합물을 얻게 되었다.100 kg of waste mats for automobiles were put into the cutting machine 1 and cut into pieces of 10 to 20 cm in length into the primary grinding machine 3 through the combier 2 and coarsely pulverized to have a length of about 10 mm. A mixture of polyester with a fibrous component and PVC particles with a solid component was obtained.
이와 같은 혼합물을 팬으로 강제 분사시켰던바 분사물 가운데 비중이 가벼운 섬유사 등의 폴리에스텔 성분은 부유 상승하여 스크류식 이송로(19)에 의해 섬유질수집통(14)으로 이송되었고 비중이 무거운 입자상의 PVC 성분은 낙하되어 1차분류기(5) 하방의 좌우로 분할 설치된 2차분쇄기(6), (6')내로 투입된후 길이 5㎜범위로 분쇄된 분쇄물을 얻게 되었다.As a result of the forced injection of such a mixture into a fan, polyester components such as light yarns having light specific gravity were suspended in the air and transferred to the fibrous container 14 by a screw feed passage 19, and the heavy specific gravity The PVC component was dropped and introduced into the secondary grinders 6 and 6 'installed separately to the left and right under the primary classifier 5, thereby obtaining a pulverized product pulverized to a range of 5 mm in length.
이때 얻어진 분쇄물 가운데는 섬유질과 미입자가 혼합되어 있어 이것을 팬(7), (7')을 이용하여 2차분류기(8), (8')내로 이송하여 시켰던바 이 가운데 있어 비중이 가벼운 섬유사 등의 폴리에스텔 섬유실은 위로 부상되어 스크류식 이송로(19)에 모셔진 다음 스크류에 의해 섬유질수집통(14)으로 이송되었고 비중이 무거운 PVC 입자는 하강하여 여과망(10), (10')을 통해 대부분 투하되고 일부분은 여과망 위에 수집되었다.In the pulverized product obtained at this time, fibers and fine particles were mixed and transferred to the secondary classifiers (8) and (8 ') by using fans (7) and (7'). Polyester fiber yarns such as yarns were lifted up and entrained in the screw feed path 19, and then transferred to the fibrous container 14 by screws, and heavy PVC particles were lowered to lower the filter nets 10 and 10 '. Most of them were dropped and some were collected on the screen.
이때 팬(9), (9')에 의해 여과망(10), (10')위에 수집된 섬유질 등의 물질은 강제로 부상시켜 분류기(8), (8') 상부에 설치된 스크류식 이송로(19)를 통해 섬유질수집통(14)내로 이송되었고 여과망(10), (10')을 통해 낙하된 미입자는 팬(9), (9')의 작용에 의해 3차분류기(11)에 투입 분사시켰던바 PVC 입자에 부착되어 있던 섬유질 등의 미세물은 탈리 부상되어 스크류식 이송로(19)를 통해 섬유질수집통(14)내로 이송되었고 비중이 무거운 PVC 입자는 여과망(13)을 거쳐 정선된 상태가 되어 PVC수집통(15)내로 수집되었다.At this time, materials such as fibers collected on the filter net 10, 10 'by the fans 9, 9' are forcibly floated and screw-type conveying paths installed on the upper parts of the classifiers 8, 8 '( 19, the fine particles transported into the fibrous container 14 and dropped through the filtering nets 10 and 10 'are introduced into the tertiary sorter 11 by the action of the fans 9 and 9'. The fine particles such as fibers attached to the PVC particles were sprayed and detached and transferred to the fiber collecting container 14 through the screw transfer path 19, and the PVC particles having a high specific gravity were selected through the filtering network 13. It was brought into the state and collected into the PVC container (15).
이상에서 얻어진 섬유질수집공(14)내에 수집된 섬유질은 마치 솜뭉치처럼 되어 있었으나 이를 쌍스크류 단일압출식으로된 압출기(16)에 넣어 200∼250℃의 열을 가하여 칩(17)을 얻은후 이를 송수관 압출소재로 사용하였던바 신재에 못지않는 양질의 송수관을 얻게 되었다.The fiber collected in the fibrous collecting hole 14 obtained above was like a cotton ball, but it was put in a twin screw single extrusion extruder 16 and heated at 200 to 250 ° C. to obtain a chip 17. As the water pipe extrusion material was used, a quality water pipe as good as new material was obtained.
그리고 PVC 재료수집통(15)에 수집된 입자를 쌍스크류 단일압출기에 투입하여 150∼200℃의 가열로 칩(18)으로 압출한후 이를 신발창, 시트 또는 메트의 성형 소재로 활용하였던바 신소재에 못지 않게 좋은 제품을 얻게 되었다.In addition, the particles collected in the PVC material container 15 were put into a twin screw single extruder, extruded into chips 18 by heating at 150 to 200 ° C., and then used as a molding material for shoe soles, sheets or mats. I got a good product.
이상과 같이 본 발명은 융점이 각각 다른 이질성 수지로된 승용차용 폐메트를 재활용함에 있어 이를 절단 분쇄한후 사이크론 분리식으로 비중차를 이용하여 분리하는 과정 폴리에스텔 섬유와 PVC수지의 비중차에 의해 분리되어진 것을 다시 압출기를 통해 칩(18)을 얻고 이를 농수를 개설용 상수관 및 신발창 또는 메트나 시트의 성형소재로서 재활용하였던바 양질의 신발창이나 시트를 얻게 되었다.As described above, in the present invention, in the recycling of waste mats for passenger cars made of heterogeneous resins having different melting points, they are cut and pulverized and separated using a specific gravity difference in a cyclone separation method. The chip 18 was separated through the extruder, and the waste water was recycled as a molding material for opening water pipes and shoe soles or metna sheets, thereby obtaining a high quality shoe sole or sheet.
이상과 같이 본 발명은 재료구성이 다른 메트나 시트의 폐재를 재활용되게 함에 있어 이를 절단 분쇄하여 비중차를 이용하여 분리할수 있게 하였기 때문에 산업폐기물 재활용은 물론 제2의 공해발생을 방지할 수 있어 매우 유용한 발명이다.As described above, in the present invention, since waste materials of different mats and sheets are recycled, they can be cut and pulverized and separated using specific gravity differences, thereby preventing industrial waste recycling as well as generating second pollution. It is a useful invention.
