폐플라스틱 재활용 팰릿 제조에 적용되는 도금 플라스틱 선별장치{Plating plastic sorting equipment applied to the manufacture of waste plastic recycling pallet}Plating plastic sorting equipment applied to the manufacture of waste plastic recycling pallet

개시되는 내용은 폐플라스틱을 분쇄한 후 파쇄물을 컨베이어벨트를 이용하여 이송하는 과정에서 자착이 되는 철이 함유된 플라스틱을 선별해낼 수 있도록 하는 폐플라스틱의 재활용 팰릿 제조용 정전 분리기에 관한 것이다.The present disclosure relates to an electrostatic separator for manufacturing waste plastic recycling pallets that can sort out iron-containing plastics that become magnetic in the process of transporting the shreds using a conveyor belt after crushing the waste plastics.

본 명세서에서 달리 표시되지 않는 한, 이 섹션에 설명되는 내용들은 이 출원의 청구항들에 대한 종래 기술이 아니며, 이 섹션에 포함된다고 하여 종래 기술이라고 인정되는 것은 아니다.Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and inclusion in this section is not an admission that it is prior art.

플라스틱은 초기에 금속, 목재, 유리, 도자기, 피혁 등의 대용품으로 등장하였으나 경량성, 강인성, 내부식성, 착색성, 대량생산 가능성 등을 가지고 있으며, 특히 탁월한 가공성의 장점 때문에 현대에는 전기, 전자, 기계, 건축, 기타분야에서 필수Plastics appeared as substitutes for metal, wood, glass, ceramics, and leather in the early days, but they have lightness, toughness, corrosion resistance, colorability, and the possibility of mass production. , architecture, and other fields

불가결한 재료로서 대용품이 아닌 새로운 재료로의 자리를 확고히 차지하기에 이르렀다.As an indispensable material, it has firmly established itself as a new material rather than a substitute.

플라스틱은 가열이나 가압 또는 이 두가지 방법에 의해 만들어지는 성형이 가능한 재료나, 이러한 재료를 사용한 성형품의 총칭으로 분자량이 크며 제조과정중 유동성을 이용하여 원하는 형태를 만들게 된다.Plastic is a material that can be molded by heating, pressurization, or these two methods, or a general term for molded products using these materials.

플라스틱은 성형의 용이함으로 인해 다양한 분야에서 활용되지만, 활용분야가 많은 만큼 활용되고 버려진 폐플라스틱 처리에 관한 문제도 심각하다.Plastics are used in various fields due to their ease of molding, but the problem of disposal of waste plastics that are used and discarded is serious as there are many fields of application.

급속한 산업의 발전과 더불어 발생하기 시작한 플라스틱 폐기물에 대해 우리나라가 관심을 가지고 법적으로 대처하기 시작한 것은 1979년 "합성수지 폐기물 처리사업법"의 제정에 따라 1980년 "한국자원재생공사"가 설립되면서부터 이며, 1992년말 "자원절약과 재활용촉진에 관한 법률"의 제정과 1993년 총리령으로 "제품의 포장방법 및 포장재의 재질 등의 기준에 관한 법률" 등에서 발생원 감량화를 꾀하고 있다.With the rapid industrial development, Korea began to take an interest in and legally respond to plastic waste, which was established in 1980 with the establishment of the "Synthetic Resin Waste Treatment Business Act" in 1980. At the end of 1992, the "Resource Conservation and Recycling Promotion Act" was enacted, and by the Prime Minister's Ordinance in 1993, the "Act on Standards for Packaging Methods and Materials of Products, etc.", etc., are trying to reduce the source of generation.

폐플라스틱의 발생량은 국내 실수요량의 함수이나 각 플라스틱의 품목별, 용도별로 사용기간 또는 회수에 소요되는 기간이 모두 다르기 때문에 간단하지는 않다.The amount of waste plastic generated is a function of the actual domestic demand, but it is not simple because the period of use or recovery time is different for each item and use of each plastic.

일반 가정의 생활 쓰레기를 비롯하여 산업 쓰레기로부터 발생되는 플라스틱 폐기물은 그 처리에 있어서, 이제까지 심각한 문제를 야기 시켜 왔다. 플라스틱 폐기물은 1차로 분리되어 수거되지만, 이를 적절히 재활용하기란 거의 불가능한 실정이다. 1차로 분리수거된 플라스틱 폐기물은 대체적으로 플라스틱류가 약 70% 정도를 차지하고, 종이류가 약20% 그리고 나무나 기타 불순물이 약 10%를 차지한다. 이러한 플라스틱 폐기물은 이제까지 매립지를 선정하여 매립하여 왔다.Plastic waste generated from industrial waste, including household waste, has so far caused serious problems in its treatment. Although plastic waste is primarily separated and collected, it is almost impossible to properly recycle it. Plastic wastes primarily separated and collected are generally about 70% plastic, 20% paper, and 10% wood or other impurities. These plastic wastes have been landfilled by selecting a landfill site so far.

그러나 오늘날은 이러한 매립지를 선정하기가 어렵고, 매립지를 찾아 매립한다 하여도 각종 수질오염을 비롯한 환경문제를 야기키는 문제점이 있었다.However, these days, it is difficult to select such a landfill, and even if a landfill site is found and reclaimed, there is a problem that causes environmental problems including various water pollution.

대한민국 등록특허 10-0566065호에는 「폐플라스틱을 이용한 재활용 플라스틱 펠렛 및 그의 제조방법」이 개시되어 있다. Korean Patent Registration No. 10-0566065 discloses "recycled plastic pellets using waste plastic and a method for manufacturing the same".

종래 기술은 습식 세척방식을 활용하여 폐합성수지의 오물을 제거하고, 탈수과정으로 수분을 완벽하게 제거한 후 펠렛 제조장치로 운반하게 된다. The prior art removes the dirt of the waste synthetic resin by using a wet washing method, and after completely removing moisture through a dehydration process, it is transported to the pellet manufacturing apparatus.

운반하는 과정에서 자력을 이용하여 비철금속과 철금속이 혼합된 플라스틱 분쇄물을 분리하게 된다. In the process of transporting, magnetic force is used to separate pulverized plastics mixed with non-ferrous metals and ferrous metals.

그러나 종래에는 도금된 플라스틱이 혼입되는 경우 분리가 어려웠다. 따라서 이를 분리하기 위해 도금 제품 분리기, 즉 금속 선별기를 추가로 사용하여야 한다. 이는 주로 컨베이어벨트 주변에 배치되어 자착력에 의해 분리시키도록 하였으나 성능이 미흡하였다. However, in the prior art, when the plated plastic is mixed, it is difficult to separate. Therefore, in order to separate them, it is necessary to additionally use a plating product separator, that is, a metal separator. It was mainly arranged around the conveyor belt and separated by magnetic force, but the performance was insufficient.

개시되는 내용은 폐플라스틱을 재생 또는 재활용 하기 위한 펠릿을 제조하되 플라스틱 재료인 ABS, PS, PP가 혼합된 폐플라스틱 파쇄물을 컨베이어벨트를 이용하여 이송하는 동안 자착력에 의해 철성분이 함유된 플라스틱 재료를 분리시킬 수 있도록 하되 자력발생부의 구성을 간결하면서도 성능이 향상될 수 있도록 한 폐플라스틱의 재활용 팰릿 제조용 정전 분리기를 제공하는데 그 목적이 있다.Disclosed is a plastic material containing iron by magnetic attraction while manufacturing pellets for recycling or recycling waste plastics, but transporting crushed waste plastics mixed with ABS, PS, and PP plastic materials using a conveyor belt It is an object of the present invention to provide an electrostatic separator for manufacturing waste plastic recycling pallets that can separate the waste plastics, while simplifying the configuration of the magnetic force generating unit and improving the performance.

먼저 도 3 및 도 4에 도시된 바와 같이, 본 발명에 따른 도금 플라스틱 선별장치가 적용된 폐플라스틱의 재활용 정전 분리 장치에 대해 설명하면, 폐플라스틱 재료가 투입되는 호퍼(2); 호퍼(2)에서 유입된 폐플라스틱 재료를 세척후 탈수시키는 세척부(4); 세척된 폐플라스틱 재료를 건조시키는 가열부(5); 상기 가열부(5)에서 건조된 폐플라스틱 재료를 이송하는 컨베이어벨트(62)와, 컨베이어벨트(62)에서 이송된 재료가 투입되는 분리통(64)으로 구성되어, 상기 분리통(64)을 회전시켜서 플라스틱 재료의 표면에 묻은 플라스틱 가루를 제거하는 이물 분리기(6); 수분이 건조된 폐플라스틱 재료를 정전효과에 의해 분리하는 정전 분리기(7); 정전 분리기(7)에서 분리된 폐플라스틱 재료 중에 금속입자가 혼합된 폐플라스틱 재료를 선별하는 도금 플라스틱 선별장치(A);를 포함한다. First, as shown in FIGS. 3 and 4, the electrostatic separation device for recycling waste plastic to which the plating plastic sorting device according to the present invention is applied will be described. The hopper 2 into which the waste plastic material is put; a washing unit 4 for washing and dehydrating the waste plastic material introduced from the hopper 2; a heating unit 5 for drying the washed waste plastic material; It is composed of a conveyor belt 62 for transferring the waste plastic material dried by the heating unit 5 and a separator 64 into which the material transferred from the conveyor belt 62 is put, a foreign material separator 6 which rotates to remove plastic powder adhered to the surface of the plastic material; an electrostatic separator 7 that separates the dried waste plastic material by electrostatic effect; and a plating plastic sorting device (A) for sorting the waste plastic material mixed with metal particles from the waste plastic material separated by the electrostatic separator (7).

그리고 상기 정전 분리기(7)에서 정전 분리된 폐플라스틱 재료의 먼지나 분진을 제거하는 집진기(9)를 포함한다. and a dust collector 9 for removing dust or dust from the waste plastic material electrostatically separated by the electrostatic separator 7 .

상기 집진기(9)에서 집진 후 폐플라스틱 재료에 대해 정전 효과에 의해 분리하는 2차 정전 분리기(7')를 더 포함할 수 있다. After collecting dust in the dust collector 9, a secondary electrostatic separator 7' that separates the waste plastic material by an electrostatic effect may be further included.

폐플라스틱 재료는 플라스틱 폐품을 분쇄한 것으로 대략 30×30mm 이하 크기이며, 이송 중에서 세척부(4)를 통과하면서 물로 세척된다. The waste plastic material is pulverized plastic waste and has a size of about 30×30 mm or less, and is washed with water while passing through the washing unit 4 during transport.

세척부(4)는 호퍼에서 유입된 폐플라스틱 재료를 컨베이어벨트(62를 통과하는 동안 외부에서 고압의 물을 뿌려서 세척후 탈수시킨다. The washing unit 4 sprays high-pressure water from the outside while passing the conveyor belt 62 on the waste plastic material introduced from the hopper, and then dehydrates it after washing.

이후 세척된 폐플라스틱 재료는 컨베이어벨트(62)를 타고 이송되는 과정에서 가열부(5)의 열풍기를 통과하면서 수분이 건조되도록 한다. Thereafter, the washed waste plastic material passes through the hot air blower of the heating unit 5 while being transported on the conveyor belt 62 so that moisture is dried.

이렇게 이송되는 과정에서 폐플라스틱 재료는 이미 1차 분쇄된 상태에서 뒤섞이면서 이송되므로 이송 과정에서 작은 플라스틱 가루들이 정전기에 의해 표면에 달라붙은 상태가 된다. In the process of transporting in this way, the waste plastic material is mixed and transported in the state of being first crushed, so small plastic powders are attached to the surface by static electricity during the transport process.

이물 분리기(6)는 이러한 폐플라스틱 재료에 묻어있는 플라스틱 가루를 제거하기 위한 것으로, 폐플라스틱 재료를 분리통(64)에 넣고 고속 회전시킴으로써 표면에 달라붙어있던 플라스틱 가루가 떨어지도록 하여 분리시키는 것이다. The foreign material separator 6 is to remove the plastic powder attached to the waste plastic material, and the waste plastic material is put into the separation container 64 and rotated at high speed to separate the plastic powder adhering to the surface to fall off.

분리통(64)에는 다수의 통공이 형성되어 있으므로 플라스틱 가루가 통공을 통해 배출될 수 있고, 덩어리로 된 폐플라스틱 재료는 분리통(64) 내에 남게 된다. Since a plurality of through holes are formed in the separation vessel 64 , the plastic powder can be discharged through the through holes, and the waste plastic material in a lump remains in the separation vessel 64 .

이물 분리기(6)에서 분리된 폐플라스틱 재료는 실리콘 분리기(미도시)로 이송된다.The waste plastic material separated by the foreign material separator 6 is transferred to a silicon separator (not shown).

실리콘 분리기는 고무와 실리콘 재료로 분리하는 것으로, 실리콘 선별유닛을 이용하여 고무와 실리콘 재료를 분리하고, 고압 에어로 불어서 분리시키게 된다. The silicone separator separates the rubber and the silicone material, and uses a silicone sorting unit to separate the rubber and the silicone material, and blows with high-pressure air to separate it.

이후 진동 이송기로 이송되어 진동과 동시에 이송된다. After that, it is transferred to the vibrating transfer machine and transferred at the same time as the vibration.

선별된 폐플라스틱 재료는 정전 분리기에 공급되어 전하 차이를 이용하여 분리하게 된다. The sorted waste plastic material is supplied to an electrostatic separator to separate it using a charge difference.

실시예에 따르는 폐플라스틱 재활용 팰릿 제조에 적용되는 도금 플라스틱 선별장치(A)는, 기대(120); 기대(120)에 회전가능하게 결합되며, 수평방향으로 배치되는 복수개의 회전드럼(200); 복수개의 회전드럼(200)에 권취되어 회전되며 플라스틱 재료를 이송하는 컨베이어벨트(100); 회전드럼(200)을 회전시키는 동력부(미도시); 회전드럼(200)의 하부에 형성되는 분리대(300); 및 회전드럼(200)에 외접하며 회전되는 방향에 하부 사분점에 수직하게 형성되어 컨베이어벨트의 표면을 긁어내도록 하는 스크래퍼(400);를 포함하여 구성된다. The plating plastic sorting device (A) applied to the manufacturing of waste plastic recycling pallets according to the embodiment includes a base 120; A plurality of rotating drums 200 rotatably coupled to the base 120 and arranged in a horizontal direction; A conveyor belt 100 that is wound around a plurality of rotating drums 200 and rotates to transport a plastic material; a power unit (not shown) for rotating the rotating drum 200; Separator 300 formed in the lower portion of the rotary drum 200; and a scraper 400 circumscribed to the rotating drum 200 and formed perpendicular to the lower quadrant in the rotating direction to scrape the surface of the conveyor belt.

회전드럼(200)은 자력발생부(220)가 형성되어 자착력이 발생되도록 한 것이다. The rotating drum 200 is such that a magnetic force generating unit 220 is formed to generate a magnetic force.

회전드럼(200)은 자기력이 발생되도록 하여 컨베이어벨트(100)에 이송중인 도금된 플라스틱 재료를 자착력에 의해 선별해낼 수 있다. The rotating drum 200 generates a magnetic force so that the plated plastic material being transferred to the conveyor belt 100 can be selected by magnetic adhesion.

회전드럼(200)은 10,000~15,000 가우스의 자력세기를 발휘하도록 함이 바람직하다. It is preferable that the rotating drum 200 exerts a magnetic force of 10,000 to 15,000 gauss.

일 예에 따르면, 회전드럼(200)의 내부에 영구자석이 설치되어 자력발생부(220)를 형성하게 된다. According to an example, a permanent magnet is installed inside the rotating drum 200 to form the magnetic force generating unit 220 .

또는 회전드럼(200)의 내부에 전자석이 설치되어 자력발생부(220)를 형성하게 된다. Alternatively, an electromagnet is installed inside the rotating drum 200 to form the magnetic force generating unit 220 .

자력발생부(220)에서 10,000~15,000 가우스의 자력이 가해지면 도금된 플라스틱 재료(P2), 즉 비철이라하더라도 소량의 철 성분이 포함되어 있으므로 강한 자력에 의해 자착될 수 있다. When a magnetic force of 10,000 to 15,000 gauss is applied from the magnetic force generating unit 220, the plated plastic material P2, that is, even non-ferrous, contains a small amount of iron, so it may be magnetically attached.

컨베이어벨트(100)에 적재된 상태로 이동하던 과정에서 회전드럼(200)이 있는 위치에서 컨베이어벨트(100)가 회전되면서 180도 반전되면 그 상부에 적재되어 있던 플라스틱 재료들이 대략 회전드럼의 좌측 사분점(t2)에서부터 낙하하게 된다. In the process of moving while being loaded on the conveyor belt 100, when the conveyor belt 100 is rotated 180 degrees at the position where the rotating drum 200 is located, the plastic materials loaded on the top are approximately on the left side of the rotating drum. It falls from the equinox t2.

분리대(300)는 하부는 폭이 넓고 상부로 갈수록 폭이 좁아지면서 선단이 뾰족하게 형성되는 판상으로 이루어지고, 상부 선단이 회전드럼(200)의 좌측 사분점(t2)을 지나는 가상의 수직선에 위치되도록 배치된다. Separator 300 is made of a plate shape with a sharp tip formed as the lower part is wide and the width narrows toward the upper part, and the upper tip is located on an imaginary vertical line passing the left quadrant t2 of the rotary drum 200 placed so as to

따라서 낙하하는 플라스틱 재료들이 분리대(300)의 일측면(도면상 좌측임)으로 낙하하게 되어 분리시켜 수거할 수 있게 된다.Accordingly, the falling plastic materials fall to one side (left side in the drawing) of the separator 300 so that they can be separated and collected.

회전드럼(200)에 자착된 철 성분의 도금 플라스틱 재료들은 여전히 반전된 컨베이어벨트(100)에 자착된 상태로 이동하게 되고, 이후에는 스크래퍼(400)에 의해 제거된다. The plated plastic materials of the iron component attached to the rotating drum 200 are still moved while being attached to the inverted conveyor belt 100 , and then removed by the scraper 400 .

스크래퍼(400)는 회전드럼(200)의 하부 사분점(t1)에 수직하게 형성되며, 상단이 컨베이어벨트(100)에 밀착되도록 형성된다. The scraper 400 is formed perpendicular to the lower quadrant t1 of the rotating drum 200 , and its upper end is formed to be in close contact with the conveyor belt 100 .

스크래퍼(400)는 판재 형상이며, 그 상단부가 회전드럼(200)의 하부 사분점(t1)에 위치할 수 있도록 형성되고 컨베이어벨트(100)의 외면에 접촉됨으로써 컨베이어벨트(100)에 붙어있는 자착된 도금 플라스틱 재료(P2)를 긁어내어 제거하게 된다. The scraper 400 has a plate shape, and its upper end is formed so as to be positioned at the lower quadrant t1 of the rotary drum 200 and is attached to the conveyor belt 100 by contacting the outer surface of the conveyor belt 100 . The plated plastic material (P2) is scraped off and removed.
