폐아스콘 재생설비의 목적은 분쇄 및 선별 후에 나온 재생골재(11')를 운반하여 가열기로 보내 가열하여 재생 아스콘을 생산하거나, 가열된 폐아스콘(11)의 일정량을 신제 아스콘에 혼합하는 데에 있다.
이러한 폐아스콘 재생설비를 보면 종래에는 엘리베이터 방식(출원번호 10-2001-0053046)과 광차방식(등록번호 20-0435258)이 있는데 양자 다 문제점이 있다.
즉 종래의 엘리베이터 방식을 보면, [도 1]에 보인 바와 같이, 폐아스콘 수집, 분쇄, 야적, 정량공급(BF), 이송(컨베이어BC1), 가열(가열기), 이송(컨베이어BF,BC2), 이송(버켓 엘리베이터), 임시저장(홀딩 빈HB), 저장(저장조50), 계량(계량 빈43), 이송(벨트 컨베이어BC3), 혼합, 배출의 순서로 구성되는데,
상기 엘리베이터 방식의 경우는, 폐아스콘은 가열 후에 온도가 떨어져 식을 때 생기는 특유의 접착성 때문에, 이송 수단인 버켓 엘리베이터(20)와 컨베이어 벨트, 등 보온이 곤란한 운반설비에는 가열된 골재가 식는 과정에서 골재의 미분(微粉)이 달라붙어 그것을 제거하는 등의 보수작업 때문에 생산에 지장이 많았다.
즉, 벨트 컨베이어는 톱니 형 스크레이퍼(scraper)를 헤드드럼 측에 설치하여 벨트 표면을 긁어줌으로써 고착화되는 문제점을 다소 해결할 수가 있었으나 버켓 엘리베이터의 다수의 버켓들은 물론 엘리베이터 내벽 하단부 종동 풀리 부근에서 생기는 케이크로 인해 엘리베이터가 서 버리므로 이삼일에 한 번씩 버켓 엘리베이터 하단부를 해체하여 사람이 직접 긁어내어야 했다. 이는 한 마디로 기계화된 설비라고 할 수가 없는 것이었다.
종래의 다른 한 방식인 광차(鑛車)방식, 일명 스키프(Skip)방식을 보면, 폐아스콘 수집, 분쇄, 야적, 정량공급(BF), 이송(컨베이어BC1), 임시저장, 이송(광차), 저장(저장조50), 계량(계량빈43), 이송(벨트 컨베이어BC3), 혼합, 배출의 순서로 구성되는 것도 있다.
이 광차 방식은 상기 엘리베이터 방식의 엘리베이터의 자리에 광차를 설치한 것으로 또 다른 문제점이 있다. 즉, 폐아스콘의 고착을 방지하기 위해 광차 버켓 내면에 정기적으로 경유를 살포하기 때문에 대기를 오염시키고, 광차가 사행(蛇行)레일을 타고 오르내리는 구조인 바, 저면에서 싣고 고속으로 올라가 정부에서 덤핑하려고 급정지하는데 그때마다 마찰소음이 나서 시끄러우며, 광차를 끄는 와이어 로프를 자주 교체해야 하고, 흔치 않은 일이지만 로프가 끊어져 광차가 떨어지는 사고도 생기는 문제점이 있다.
The purpose of the waste ascon regeneration facility is to transport regenerated aggregate (11 ') after crushing and sorting and to send it to a heater for heating to produce regenerated ascon, or to mix a certain amount of heated waste ascon (11) with new ascon. .
Looking at such waste ascon regeneration facilities, there are conventional elevator system (application number 10-2001-0053046) and light-car system (registration number 20-0435258), which both have problems.
That is, in the conventional elevator system, as shown in Fig. 1, waste ascon collection, crushing, yard, quantitative supply (BF), transfer (conveyor BC1), heating (heater), transfer (conveyor BF, BC2), Consists of order of transfer (bucket elevator), temporary storage (holding bin HB), storage (storage bin 50), weighing (measuring bin 43), transfer (belt conveyor BC3), mixing and discharging.
In the case of the elevator system, the waste ascon is a process in which heated aggregate cools in a transport facility such as a bucket elevator 20 and a conveyor belt, which are difficult to insulate, due to the unique adhesiveness caused when the temperature drops after heating. Due to maintenance work such as fine powder of aggregate sticking to and removing it, production was difficult.
In other words, the belt conveyor could solve the problem of fixing by installing a sawtooth scraper on the head drum side and scraping the belt surface. As the elevator stood out, it had to dismantle the lower part of the bucket elevator every two or three days and scrape by person. In short, it was not a mechanized facility.
In another conventional method, the light car method, also known as the skip method, waste ascon collection, pulverization, yard, quantitative supply (BF), transport (conveyor BC1), temporary storage, transport (light car) It may be configured in the order of storage (storage tank 50), weighing (meter bin 43), conveyance (belt conveyor BC3), mixing and discharging.
This light car system has another problem in that the light car is installed in place of the elevator of the elevator system. In other words, it is a structure that pollutes the air by periodically spraying light oil on the inner surface of the wagon bucket to prevent the sticking of the used ascon, and the wagon is lifted up and down on the meandering rail. To stop suddenly, the noise is so noisy every time, the wire rope to pull out the wagons often need to be replaced, but there is a problem that the wagons fall due to broken ropes.

본 발명은 [도 2]와 [도 3] 및 [도 5]와 같이 회전식 가열기(30)의 배출구를 저장조(51)에 직결시킴으로써 가열 후 저장조(50)로의 운반공정을 없애는 것이다.
한 편 벨트 컨베이어의 표면(BC2,BC3)을 긁어주기 위해 초경재료의 스크레이퍼를 헤드드럼 측에 설치하여 운전과 동시에 부착물을 제거하는 것이다.
가열기(30)의 배출구를 저장조(51)에 직결시킬 경우, 가열기(30)는 종래의 방식보다 높은 위치에 설치되므로 재생골재(11')를 넣고 회전할 때 생기는 진동 때문에 구조적으로 튼튼해야 할 필요가 있다.
The present invention eliminates the transport process to the storage tank 50 after heating by directly connecting the outlet of the rotary heater 30 to the storage tank 51 as shown in FIGS. 2, 3 and 5.
On the other hand, in order to scrape the surface (BC2, BC3) of the belt conveyor, a scraper of cemented carbide material is installed on the head drum side to remove the attachment at the same time as the operation.
When the outlet of the heater 30 is directly connected to the reservoir 51, since the heater 30 is installed at a higher position than the conventional method, it needs to be structurally strong because of vibration generated when the recycled aggregate 11 'is inserted and rotated. There is.
