Improved household waste to increase energy productivity as well as recycling efficiency by collecting only vinyl from the washed household waste after washing and reproducing it as solid fuels It relates to a conveyor system used for separating and fueling vinyls contained in
일반적으로, 일상생활에서 사용되는 음식물을 비롯한 각종 생활쓰레기들 중 자원재활용이 가능한 쓰레기는 통상 가정에서 종량제봉투라 불리우는 일정 규격을 가진 비닐봉투에 봉입되어 매립지로 운반된 후, 다시 산업에너지원으로 재활용된다.In general, among various household wastes including food used in daily life, garbage that can be recycled as a resource is sealed in a plastic bag with a certain standard called a pay-as-you-go bag at home, transported to a landfill, and then recycled as an industrial energy source. do.
즉, 각종 생활쓰레기 중 재활용이 가능한 쓰레기는 일차적으로 파봉공정을 거쳐 잘게 부서진 후, 자력이나 기타 스크린 등의 선별방식을 통해 쓰레기를 선별하여 제거하고 재활용 가능한 상태로 변환된다.That is, among various household wastes, recyclable waste is primarily broken into small pieces through a sealing process, and then the waste is sorted and removed through a sorting method such as magnetic force or other screens, and then converted into a recyclable state.
여기에서, 생활폐기물의 선별은 주로 파봉 후 작업자가 수작업을 통한 수선별로 이루어지기 때문에 각종 악취는 물론, 선별 효율이 떨어지고, 작업환경이 열악하여 작업자들이 기피하는 현상이 증가하고 있다.Here, since the sorting of domestic waste is mainly done by manual repair by workers after breaking, the phenomenon that workers avoid it due to various odors as well as poor sorting efficiency and poor working environment is increasing.
그리고, 선별물들 중에서 비닐류는 재활용 가능성과 에너지생산성이 매우 높기 때문에 회수 후 재생할 수 있다.And, among sorted materials, vinyl can be recycled after recovery because it has a very high recyclability and energy productivity.
그런데, 비닐류는 크기나 종류, 무게가 다양해서 선별하기가 쉽지 않고 수작업으로 선별하는 수선별의 경우에는 효율이 많이 떨어지기 때문에 이에 대한 개선이 필요하다.However, it is not easy to sort vinyls because they have various sizes, types, and weights, and in the case of manual sorting, the efficiency is greatly reduced, so improvement is needed.
또한, 선별된 비닐류는 즉시 재활용이 어렵고 집하장에 모아 따로 처리하고 있기 때문에 고형연료로의 재생산성이 떨어지는 단점도 있다.In addition, there is a disadvantage in that the reproducibility of the solid fuel is poor because it is difficult to immediately recycle the sorted vinyls and they are collected in a collection point and treated separately.
본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점들을 감안하여 이를 해결하고자 창출된 것으로, 생활폐기물를 회수하여 파봉 후 세척할 때 생활폐기물에 포함된 먼지, 흙 등의 이물질을 자동으로 완전히 세척처리한 후 세척된 생활폐기물들 중에서 비닐류만 따로 모아 고형연료(Solid Fuels)로 재생산함으로써 재활용 효율은 물론 회수되는 비닐의 순도까지 높일 수 있고, 이에 따라 에너지생산성을 향상시킬 수 있도록 개선된 생활폐기물에 함유된 비닐류의 분리 및 연료화시 사용되는 컨베어시스템을 제공함에 그 주된 목적이 있다.The present invention was created to solve the problem in view of the various problems in the prior art as described above, and when household waste is collected, sealed, and then washed, foreign substances such as dust and soil contained in household waste are automatically and completely washed and treated. By collecting only vinyls from washed household wastes and reproducing them as solid fuels, the recycling efficiency as well as the purity of recovered vinyls can be increased, thereby improving energy productivity.

도 1에 도시된 바와 같이, 본 발명에 따른 생활폐기물에 함유된 비닐류의 분리 및 연료화시 사용되는 컨베어시스템은 수거된 생활폐기물를 파봉한 후 파쇄하는 제1단계; 상기 제1단계에서 파쇄된 생활폐기물은 컨베어시스템으로 이송하면서 세척 건조하는 제2단계; 파쇄 건조된 생활폐기물을 경사형 컨베어에 투입시켜 1차 선별하는 제3단계; 1차 선별된 낙하물을 빗자루질하여 잔류된 비닐만 걷어내는 제4단계; 1차 선별된 선별물을 송풍하여 무게차로 비닐만 선별하는 제5단계; 제4,5단계에서 선별된 비닐을 컨베어를 통해 용융로로 투입시키는 제6단계; 용융된 수지를 압출하면서 커팅하고 냉각하여 펠릿을 만드는 제7단계;를 포함한다.As shown in Figure 1, the conveyor system used in the separation and fueling of vinyl contained in domestic waste according to the present invention includes a first step of shredding the collected municipal waste and then crushing it; A second step of washing and drying the household waste shredded in the first step while transferring it to a conveyor system; A third step of first sorting the shredded and dried municipal waste by putting it on an inclined conveyor; A fourth step of brushing the firstly selected falling objects to remove only the remaining vinyl; A fifth step of selecting only vinyl by weight difference by blowing the firstly selected items by air; A sixth step of introducing the vinyl selected in steps 4 and 5 into a melting furnace through a conveyor; A seventh step of making pellets by cutting and cooling the molten resin while extruding; includes.
여기에서, 상기 제1단계는 도 2의 예시와 같은 파봉유닛(10)을 통해 수행된다.Here, the first step is performed through the
예컨대, 상기 파봉유닛(10)은 생활폐기물이 담긴 봉투를 투입 안내하는 투입가이드(12)와, 상기 투입가이드(12) 상에 회전가능하게 설치되어 봉투를 이동시키는 다수의 롤러(14)와, 상기 롤러(14)의 단부에 이격설치되어 반송되는 봉투를 퍼 올리도록 드럼면에 다수의 리프팅바(B)가 고정된 리프팅드럼(16)과, 상기 리프팅드럼(16)과 간격을 두고 설치되며 파봉용 삼각나이프(K) 및 더스트 저감용 물분사노즐(N)을 갖춘 파봉가이드(18)를 포함한다.For example, the
이때, 상기 리프팅드럼(16)을 마주보는 파봉가이드(18)의 대향면은 상부에서 하부로 갈수록 리프링드럼(16)과의 간격이 점점 좁아지게 하여 파봉 효율을 높이도록 구성된다.At this time, the opposite surface of the
또한, 상기 파봉가이드(18)에는 물분사노즐(N)로 물을 공급하기 위한 물탱크(미도시)와, 물탱크내 물을 펌핑하는 펌프(미도시)가 내장되어 있으나 도시는 생략하였다.In addition, a water tank (not shown) for supplying water to the water spray nozzle (N) and a pump (not shown) for pumping water in the water tank are embedded in the
이에 따라, 파봉과 동시에 생기는 먼지는 물분사노즐(N)을 통해 분사되는 물에 의해 침강되면서 먼지를 일으키지 않게 되어 작업환경을 양호하게 한다.Accordingly, the dust generated at the same time as the sealing is settled by the water sprayed through the water spray nozzle (N) and does not cause dust, thereby improving the working environment.
그리고, 상기 제2단계에서 사용되는 컨베어시스템은 도 5 내지 도 7의 예시와 같이, Z형 플라이트 컨베어로서, 물이 채워져 있는 세척부(510)와, 상기 세척부(510)의 일단에서 수직하게 연장된 탈수부(520)와, 상기 탈수부(520)의 상단에서 수평하게 연장된 건조부(530)를 포함한다.And, the conveyor system used in the second step is a Z-shaped flight conveyor, as shown in the examples of FIGS. It includes an extended dewatering unit 520 and a drying unit 530 extending horizontally from an upper end of the dehydrating unit 520 .
이때, 상기 세척부(510)와, 탈수부(520) 및 건조부(530)는 하나의 체인(CH)에 의해 회전구동하도록 다수의 스프라켓(SP1,SP2,SP3,SP4)을 포함하며, 체인(CH)에는 바 형상의 스크래퍼(SR)가 고정되어 파쇄 선별된 비닐을 긁어 이송시킬 수 있도록 구성된다.At this time, the washing unit 510, the dewatering unit 520, and the drying unit 530 include a plurality of sprockets (SP1, SP2, SP3, and SP4) so as to be rotationally driven by one chain (CH). (CH) is configured so that a bar-shaped scraper (SR) is fixed to scrape and transfer the shredded vinyl.
또한, 상기 세척부(510)의 스프라켓(SP1) 설치부위 직상방에는 투입부(540)가 설치되어 파쇄 선별된 비닐을 투입할 수 있도록 구성된다.In addition, an input unit 540 is installed directly above the installation site of the sprocket SP1 of the washing unit 510 so as to input the shredded and sorted vinyl.
특히, 상기 세척부(510)는 수위선까지 물이 채워져 있기 때문에 투입된 비닐이 스크래퍼(SR)에 의해 끌려 가면서 물 속에서 자동적으로 세척되게 된다.In particular, since the washing unit 510 is filled with water up to the water level line, the input vinyl is automatically washed in water while being dragged by the scraper SR.
그리고, 탈수부(520)를 향해 수직 상승하게 되면 더 이상 물이 존재하지 않기 때문에 자중에 의해 쉽고 빠르게 탈수되게 된다.And, since water no longer exists when it rises vertically toward the dewatering unit 520, it is easily and quickly dehydrated by its own weight.
아울러, 상기 건조부(530)에는 천정에 열풍을 발생시키는 건조챔버(550)가 설치된다.In addition, a drying chamber 550 for generating hot air is installed on the ceiling of the drying unit 530 .
상기 건조챔버(550)는 도 7의 예시와 같이, 챔버하우징(552)과, 상기 챔버하우징(552)의 상단에 설치된 열풍팬(554)과, 상기 열풍팬(554)의 일측에 배치된 히터(556)와, 상기 챔버하우징(552)에 내장되고 상면이 개방된 열풍확산덕트(558)와, 상기 열풍확산덕트(558)의 하단면에 다수 형성된 열풍분사공(560)과, 상기 열풍확산덕트(558)의 하단면에 간격을 두고 설치되며 열풍분사공(560)과 겹치지 않게 배치된 적외선방사기(570)를 포함한다.As shown in the example of FIG. 7 , the drying chamber 550 includes a chamber housing 552, a hot air fan 554 installed on top of the chamber housing 552, and a heater disposed on one side of the hot air fan 554. 556, a hot air diffusion duct 558 built into the chamber housing 552 and having an open upper surface, a plurality of hot air blowing holes 560 formed on the lower surface of the hot air diffusion duct 558, and the hot air diffusion duct 558. It is installed at intervals on the lower surface of the duct 558 and includes an infrared emitter 570 disposed not to overlap with the hot air blowing hole 560.
이때, 상기 열풍확산덕트(558)는 밀폐된 것처럼 도시되어 있으나 이는 측단면도라서 그런것이고 상면 일부가 개방된 상태로 유지되어 열풍팬(554)에서 송풍한 고온의 공기를 수용할 수 있도록 구성된다.At this time, the hot air diffusion duct 558 is shown as being sealed, but this is because it is a side cross-sectional view, and a part of the upper surface is kept open to accommodate high-temperature air blown by the hot air fan 554.
이에 따라, 건조부(530)를 지나가는 비닐은 열풍과 적외선조사에 의해 신속하게 건조되게 된다.Accordingly, the vinyl passing through the drying unit 530 is quickly dried by hot air and infrared radiation.
결국, 본 발명에서는 자동 세척과 자동 건조가 병행되기 때문에 보다 순도가 높은 비닐 재생산이 가능하게 된다.After all, since automatic washing and automatic drying are performed in parallel in the present invention, it is possible to reproduce vinyl with a higher purity.
한편, 상기 제3단계는 비닐만 선별된 생활폐기물지만 비닐 외에 이물질이 들어 있는 경우가 흔하기 때문에 이들 이물질을 완전히 분리하기 위한 것으로 분리 선별을 용이하게 하기 위해 파쇄기로 파쇄한 후 경사형 컨베어를 통해 상승시키면서 비중차로 인해 무거운 이물질은 낙하되고 가벼운 비닐은 상승시키는 방식으로 이루어진다.On the other hand, the third step is to completely separate these foreign substances because even though only vinyl is sorted household waste, it is common that foreign substances other than vinyl are contained. Due to the difference in specific gravity, heavy foreign matter falls and light vinyl rises.
이 경우, 도 3의 예시와 같이, 경사형 컨베어(100)는 브러쉬형 컨베어벨트(110)를 포함한다.In this case, as in the example of FIG. 3, the inclined conveyor 100 includes a brush-type conveyor belt 110.
상기 브러쉬형 컨베어벨트(110)는 벨트 표면에 길이방향으로 일정간격을 두고 다수의 브러쉬(120)가 식모되어 있는 형태를 갖는다.The brush-type conveyor belt 110 has a shape in which a plurality of brushes 120 are planted at regular intervals in the longitudinal direction on the belt surface.
이러한 브러쉬형 컨베어벨트(110)는 투입기(130)를 통해 파쇄된 생활폐기물가 투입되어 낙하될 때 가벼운 비닐은 브러쉬(120)에 걸리고, 무거운 이물질은 브러쉬(120)를 누르고 통과하여 낙하하게 된다.When the shredded household waste is introduced and dropped through the feeder 130 in the brush-type conveyor belt 110, the light vinyl is caught on the brush 120, and the heavy foreign matter presses the brush 120 and passes through to fall.
이를 위해, 상기 경사형 컨베어(100)는 일정경사, 바람직하게는 30-45°의 각도를 갖고 경사배치되며, 무한궤도 형태로 회전하는 브러쉬형 컨베어벨트(110)가 낮은 곳에서 높은 곳으로 상향 회전이동하도록 구성된다.To this end, the inclined conveyor 100 is inclined at a certain inclination, preferably at an angle of 30-45 °, and the brush-type conveyor belt 110 rotating in the form of an endless orbit moves upward from a low place to a high place. It is configured to rotate.
특히, 상기 브러쉬형 컨베어벨트(110)의 경우 브러쉬(120)가 식모된 관계로 선별 분리되어야 할 이물질(중량감 있는 물질들)들의 분리 효율이 떨어질 수 있다. 때문에, 본 발명에서는 상기 브러쉬(120)가 브러쉬형 컨베어벨트(110) 전체 길이를 4등분하는 지점에 총 4줄이 형성됨이 바람직하다.In particular, in the case of the brush-type conveyor belt 110, since the brush 120 is planted, the separation efficiency of foreign substances (heavy substances) to be sorted and separated may decrease. Therefore, in the present invention, it is preferable that a total of four lines are formed at the points where the brushes 120 divide the entire length of the brush-type conveyor belt 110 into quarters.
뿐만 아니라, 상기 브러쉬(120)는 뻣뻣한 모가 아니라, 쉽게 구부러지는 양모로 이루어져 비닐류만 살짝 걸쳐 올릴 수 있는 정도여서 이물질들은 쉽게 굴러 떨어지거나 미끄러져 떨어지도록 구성된다.In addition, the brush 120 is made of wool that is easily bent, not stiff hair, so that only vinyl can be slightly raised, so that foreign substances can easily roll off or slide off.
아울러, 상기 브러쉬형 컨베어벨트(110)의 표면에는 활주도포층이 형성된다. 활주도포층은 이물질들의 미끄러짐성을 높이기 위한 것으로, 폴리카보네이트수지 100중량부에 대해, 폴리테트라플로오르에틸렌 5중량부, 트리크레실 포스페이트(Tricresyl Phosphate) 5중량부, 메틸 2-메틸프롭-2-에노에이트 5중량부, 디메틸벤질리덴솔비톨 10중량부를 혼합한 혼합물이 도포되어 형성된다.In addition, a sliding coating layer is formed on the surface of the brush-type conveyor belt 110. The sliding coating layer is for improving the slipperiness of foreign substances, and based on 100 parts by weight of polycarbonate resin, 5 parts by weight of polytetrafluoroethylene, 5 parts by weight of Tricresyl Phosphate, methyl 2-methylprop-2 - A mixture of 5 parts by weight of enoate and 10 parts by weight of dimethylbenzylidene sorbitol is applied and formed.
이때, 폴리테트라플로오르에틸렌(PTFE)은 불소수지의 하나로서 낮은 마찰계수로 인해 미끄럼저항성을 낮춰 슬립성을 현저히 향상시키기 위해 첨가된다.At this time, polytetrafluoroethylene (PTFE), as one of the fluorine resins, is added to remarkably improve slip properties by lowering slip resistance due to a low friction coefficient.
그리고, 트리크레실 포스페이트는 내스티키성 및 내열성, 경화안정성을 증대시킨다.In addition, tricresyl phosphate increases sticky resistance, heat resistance, and curing stability.
또한, 메틸 2-메틸프롭-2-에노에이트(CH2C(CH3)COOCH3)는 배합물의 결합시 결합 중심에서의 결합강도를 높이고 외면에서의 마모저항성을 높이기 위해 첨가되고,In addition, methyl 2-methylprop-2-enoate (CH 2 C (CH 3 ) COOCH 3 ) is added to increase the bonding strength at the bonding center and increase the abrasion resistance at the outer surface when the compound is bonded,
뿐만 아니라, 디메틸벤질리덴솔비톨은 성분간 결합력을 증대시켜 성형품의 마모저항성이 저하되는 것을 방지한다.In addition, dimethylbenzylidene sorbitol increases bonding strength between components to prevent deterioration in wear resistance of molded products.
한편, 상기 경사형 컨베어(100)의 하측에는 간격을 두고 잔여물컨베어(200)가 설치된다.On the other hand, on the lower side of the inclined conveyor 100, the residue conveyor 200 is installed at intervals.
상기 잔여물컨베어(200)는 상기 경사형 컨베어(100)를 통해 선별된 이물질이 수집되는 컨베어로서, 수평방향으로 이동하도록 구성된다.The residue conveyor 200 is a conveyor on which foreign substances sorted through the inclined conveyor 100 are collected, and is configured to move in a horizontal direction.
그런데, 여기에는 이물질과 함께 낙하한 비닐도 일부 포함될 수 있다. 그래서, 이물질과 함께 낙하한 비닐까지 분리 수거하여 재활용하도록 함이 재활용 효율을 높일 수 있다.However, this may include some vinyl that has fallen along with foreign substances. Therefore, recycling efficiency can be increased by separating and recycling vinyl that has fallen along with foreign substances.
이를 위해, 본 발명에서는 제4단계를 수행한다.To this end, the fourth step is performed in the present invention.
상기 제4단계는 도 4의 예시와 같이, 잔여물컨베어(200)이 길이 일부에 구동원에 의해 일방향으로 회전하는 드럼(210)이 설치되고, 상기 드럼(210)에는 일정간격을 둔 다수의 빗자루살(220)이 설치되어 잔여물컨베어(200)의 표면과 일정간격을 두고 이격된 상태에서 회전되면서 낙하물 중에 포함된 비닐을 빗자루로 쓸듯이 쓸어 넘기는 단계이다.As shown in the example of FIG. 4, in the fourth step, a drum 210 rotating in one direction by a driving source is installed on a part of the length of the residue conveyor 200, and a plurality of brooms spaced at regular intervals are installed on the drum 210. This is a step in which the flesh 220 is installed and rotated at a predetermined distance from the surface of the residue conveyor 200 to sweep the vinyl included in the falling objects as if sweeping with a broom.
이때, 상기 잔여물컨베어(200)의 일측에는 상기 빗자루살(220)이 퍼올려 넘겨준 비닐을 받을 수 있도록 비닐수거컨베어(300)가 상기 잔여물컨베어(200)와 직교되는 방향으로 배치된다.At this time, on one side of the residue conveyor 200, a vinyl collection conveyor 300 is disposed in a direction orthogonal to the residue conveyor 200 so that the broom teeth 220 can receive the vinyl scooped up.
특히, 상기 비닐수거컨베어(300)와 잔여물컨베어(200) 사이에는 비닐 외의 이물질, 즉 상대적으로 비닐보다 무거운 이물질들은 넘어가지 못하게 하는 스토퍼판(230)이 더 설치되어 선별 효율을 높이는데 기여하도록 구성된다.In particular, between the vinyl collection conveyor 300 and the residue conveyor 200, a stopper plate 230 is further installed to prevent foreign substances other than vinyl, that is, relatively heavier than vinyl, from passing over to contribute to increasing sorting efficiency It consists of
