Abstract

PURPOSE: A method for separating rubber and steel cord of waste steel cord conveyor belt is provided to prevent safety accident, reduce labor cost and efficiently separate rubber and steel cord from the waste conveyor belt by extruding the waste conveyor belt between larger rollers. CONSTITUTION: The method is characterized in that rubber(2') and steel cord(3') are separated from the waste conveyor belt(1') by extruding the waste conveyor belt(1') between the rollers(4') at a high speed after putting waste conveyor belt(1') containing steel cord between rollers(4'), wherein rubber(2') of the waste conveyor belt(1') reaches breaking stress, and steel cord(3') reaches yield stress by compression force of the rollers(4') so that crushing is started from a part of the rubber(2') having the thinnest coating thickness in the waste conveyor belt(1') being extruded, and the steel cord(3') is projected from gaps formed on the crushed rubber part of the waste conveyor belt(1') by simultaneously breaking molecular structure of the rubber(2') and leaking aromatic oil used as softener of the belt rubber(2') by heat of high temperature instantaneously generated so that the leaked aromatic oil is penetrated into a bonding part of the rubber(2') and steel cord(3') to help delaminate the steel cord(3') from the rubber(2').

Description

폐콘베어벨트(철심)의 고무와 철심 분리기술{Rubber and Wirelope separation technique of a wasted steel cord conveyor belt}Rubber and Wirelope separation technique of a wasted steel cord conveyor belt}

본 발명은 폐콘베어벨트(철심)의 고무와 철심의 분리기술에 관한 것이다.The present invention relates to a technology for separating rubber and iron core of a waste conveyor belt (iron core).

폐콘베어벨트(철심)의 재료인 고무와 철심(와이어로프)을 분리하여 재활용하기 위해 수공구를 이용한 인력작업으로 시도해 보았으나 그 작업속도가 느리고 수작업을 통한 안전사고 발생의 우려가 있고 많은 인력을 동원하여야 하는 등 경제적으로나 작업능률면에서도 효율적이지 못하여 폐콘베어벨트(철심)을 자원으로 재생하지 못하고 대부분 소각하여 처리함으로써 아까운 자원낭비를 초래하였고, 소각에 드는 비용이 만만치가 않아 불법 투기하거나 매립하는 등 환경오염에도 큰 영향을 미치고 있다.We tried to work with manual tools to separate and recycle rubber and iron cores (wire rope), which are the materials of waste conveyor belts (iron core), but the work speed is slow, there is a risk of safety accidents caused by manual work, It is not economically and efficient in terms of work efficiency, so it is not possible to recycle waste conveyor belt (iron core) as a resource, but incineration and disposal of most of them result in waste of resources. It also has a big impact on environmental pollution.

본 발명은 이상의 문제점들을 해결 하고자 안출한 것으로 폐콘베어벨트(철심)를 대형 로울러에 넣어 압출하는 것으로 작업을 기계화하여 안전사고의 예방 뿐만아니라 인건비를 감소할 수 있고, 적은 동력으로 짧은 시간동안 많은 양을 처리할 수 있는 등 경제적으로 효율성을 높여 사업장에서 사용후 폐기되는 철심콘베어벨트의 전량을 두 종류로 쉽게 분리하여 자원화할 수 있게 한 것이다.The present invention has been made to solve the above problems by mechanizing the work by inserting the waste conveyor belt (iron core) into a large roller, which can not only prevent safety accidents, but also reduce labor costs, a large amount for a short time with a small power It is economical efficiency, such as the ability to deal with, so that the total amount of iron core conveyor belt discarded after use in the workplace can be easily separated into two types to be resourceized.

① 폐콘베어벨트 전면 (로울러 압출전)① Front side of waste conveyor belt (Before roller extrusion)

② 폐콘베어벨트 측면 (로울러 압출중)② Side of waste conveyor belt (during roller extrusion)

③ 폐콘베어벨트 압출 전면 (로울러 압출중)③ Front side of the conveyor belt belt extrusion (during roller extrusion)

④ 폐콘베어벨트 전면 (로울러 압출후)④ Waste conveyor belt front (after roller extrusion)

폐콘베어벨트(철심)(1')를 로울러(4')에 넣어 고속 압출시키면 로울러(4')의 압축력(벨트 원래의 부피에서 ⅓ ~ ¼로 축소됨)으로 폐콘베어벨트(철심)(1')의 고무(2')는 파괴응력에, 철심(3')은 항복응력에 도달하여 고무(2')분자 구조가 파괴되고 동시에 순간적으로 고열이 발생한다. 그리고 이 고열은 벨트 고무(2')의 연화제로 사용되어진 방향족 오일을 누출시켜 고무(2')와 철심(3')의 접합부분으로 침투해 들어감으로써 박리작용을 도와준다. 그리고 압출되어져 나오는 폐콘베어벨트(철심)(1')중에 고무(2')의 피복두께가 가장 얇은 부분으로 부터 파쇄가 일어나고, 그 파쇄된 틈으로 철심(3')이 돌출하여 나옴으로써 고무(2')와 철심(3')이 분리가 되는 것이다.When the conveyor belt (iron core) (1 ') is inserted into the roller (4') and extruded at high speed, the conveyor belt (iron core) (1 ') is reduced by the compression force of the roller (4') (reduced from 벨 to ¼ from the original volume of the belt). The rubber 2 'of the) reaches the breaking stress, and the iron core 3' reaches the yield stress, so that the rubber 2 'molecular structure is destroyed and at the same time, high heat is generated. And this high temperature helps the peeling action by leaking the aromatic oil used as the softening agent of the belt rubber 2 'and penetrating into the joint portion of the rubber 2' and the iron core 3 '. In the extruded waste conveyor belt (iron core) 1 ', crushing occurs from the thinnest portion of the coating thickness of the rubber 2', and the iron core 3 'protrudes into the crushed gap so that the rubber ( 2 ') and the iron core (3') are separated.

연간 2,000톤이나 되는 엄청난 양의 사업장 폐기물, 폐콘베어벨트(철심)를 로울러에 넣어 고속압출함으로써 고무와 철심(와이어로프)의 분리를 쉽게하여 소각처리 되거나 불법 매립하지 않고 전량 자원화할 수 있어 환경오염을 방지하고 재생고무를 주원료로하는 제품의 제조에 사용함으로서 산업자원과 경제발전에 이바지할 수 있다.By putting enormous amount of industrial waste and waste conveyor belt (iron core) of 2,000 tons into rollers at a high speed, the rubber and iron core (wire rope) can be easily separated and incinerated or totally recycled without illegal landfill. It can contribute to the industrial resources and economic development by using it in the manufacture of products whose main raw material is recycled rubber.
