본 발명은 건축 폐기물로부터 순환골재 등을 선별하기 위한 선별장치에 관한 것으로, 기존 건축물의 철거 시 발생하는 건축 폐기물을 일정 크기로 분쇄시킬 때 발생되는 토사 혼합골재를 원료분배기를 이용하여 골고루 분배시켜 계단식 경사판으로 이송하고 이송단계에서 계단식 경사판 후미에서 강력한 바람을 불어넣어 토사혼합골재에 혼재된 이물질을 비중의 차이로 선별하므로 양질의 순환골재를 얻을 수 있도록 하는 순환골재 선별 및 생산장치에 관한 것이다.The present invention relates to a sorting device for sorting circulating aggregates from building wastes, and evenly distributing soil mixed aggregates generated when crushing building wastes generated at the time of demolition of an existing building to a predetermined size using a raw material distributor. The present invention relates to a circulating aggregate sorting and production device that can be used to obtain high quality circulating aggregates by transferring to the inclined plate and blowing powerful wind from the stepped inclined plate at the transfer stage to select the foreign matter mixed in the soil mixture by the difference in specific gravity.

최근에는 도시의 재개발 아파트 및 대단위 아파트의 재건축 등이 활발해 짐에 따라 건축 폐기물이 매년 약 2000만톤 이상 발생되고 있으며, 향후에는 더욱 많 은 양의 건축 폐기물이 발생할 것으로 예상되고 있다.Recently, as urban redevelopment apartments and large-scale apartments are being rebuilt, more than 20 million tons of construction wastes are generated annually, and more construction wastes are expected in the future.

그러나 이와 같이 매년 발생되고 있는 건축 폐기물은, 재활용되는 빈도가 극히 미미하여 아주 극히 소량만이 도로공사의 노반 조성재나 충진 조성재로 재활용되고 있을 뿐, 나머지 대부분은 그대로 땅속에 매립되어 처분되거나 상당량이 무단 투기되어 심각한 토양의 오염을 유발시키고 있는 실정이다.However, the construction wastes generated every year are extremely infrequent, and only a very small amount is recycled as roadbed or fill composition of road construction, and most of the remaining landfills are disposed of in the ground, or a considerable amount of unauthorized dumping. The situation is causing serious soil pollution.

일반적으로 토목, 건축 폐기물로부터 골재나 기타 부산물을 재활용하기 위해 사용되는 종래의 기술은 도 1에 도시된 생산 공정도에서와 같이, 먼저 기존 건축물에서 수거된 건축 폐기물(10)은 벨트콘베이어 1(1)에 의해 이송되고, 수작업 등에 의한 1차 선별공정(S1)을 거쳐 목재 및 비닐 등의 이물질을 제거한 다음, 죠 크라셔(2) 등의 파쇄기에 의한 1차 파쇄공정(S2)을 통해 발생된 토분(5)를 분리한 후, 나머지 건축 폐기물(10)은 벨트 콘베이어 2(3,4)를 통해 이송 중 1차 자력 선별공정(S3)에서 자력 선별기(6)에 의해 금속물질(7)을 분리시켜 이동시키게 된다.Conventional techniques generally used for recycling aggregates or other by-products from civil engineering and construction wastes, as shown in the production process diagram shown in FIG. 1, firstly, the construction wastes 10 collected from existing buildings are belt conveyors 1 (1). To remove the foreign matter such as wood and vinyl through the primary sorting step (S1) by hand, etc., and then the soil powder generated through the primary shredding step (S2) by a shredder such as jaw crasher (2). After separating (5), the remaining building waste (10) separates the metallic material (7) by the magnetic separator (6) in the primary magnetic sorting process (S3) during transport through the belt conveyors 2 (3,4). Will be moved.

상기 공정 후 수작업 등에 의한 2차 선별공정(S4)을 통해 쓰레기, 비닐 등의 이물질을 제거하고, 1차 스크린 공정(S5)에 이송하면 격자 망체로 구성된 진동 스크린(8)을 통해 석분(9)을 분리해 내게 되며, 다시 육안에 의한 3차 선별공정(S6)을 통해 이물질을 제거한 다음, 2차 파쇄공정(S7)을 통해 파쇄된 건축 폐기물(10)은 마그네트 등의 2차 자력선별공정(S8)을 통하여 1차 자력 선별공정(S3)에서 잔류 되었던 철근 못 등의 금속물질(7)을 분리 해낸 다음, 격자 망체로 구성된 진동 스크린(8)을 통해 2차 스크린 공정(S9)을 거치면 모래(10a), 세골재(10b) 및 조골재(10c)로 순차적으로 분리되어 순환골재가 획득되어진다.After removing the foreign matter such as garbage and vinyl through the second sorting process (S4) by manual work after the process, and transferred to the primary screen process (S5), the stone powder (9) through a vibrating screen (8) composed of a grid mesh After removing the foreign matter through the third sorting process (S6) by the naked eye, and then the building waste (10) shredded through the second shredding process (S7) is a secondary magnetic screening process such as a magnet ( S8) to separate the metal material (7), such as the rebar nail remaining in the primary magnetic screening process (S3), and then through the second screen process (S9) through a vibrating screen (8) consisting of a grid mesh sand (10a), fine aggregate (10b) and coarse aggregate (10c) sequentially divided into circulating aggregate is obtained.

상기 공정 중, 1차 파쇄공정(S2)에서 얻어진 토사혼합골재(5)는 비닐, 스티로폼, 섬유 등의 이물질이 혼재되어 있어서 순환골재로 사용이 곤란하며, 이를 선별하기 위한 장치로 도 2 등의 습식 분류기가 다수 제안되어 있다.In the process, the soil mixture (5) obtained in the primary crushing step (S2) is difficult to use as a recycled aggregate because foreign matters such as vinyl, styrofoam, fiber, etc. are mixed, it is a device for screening this Many wet classifiers have been proposed.

도 2에 개시된 습식 분류기의 구성을 간략히 살펴보면, 1차 파쇄공정(S2) 후 얻어지는 토사혼합골재(5)를 호퍼(11)를 통해 집수조(20) 내에 연속하여 투입하면, 토사혼합골재(5)는 수중으로 침하되고 비중이 1이하인 각종 이물질은 집수조(20) 내의 수면위로 부유되는 구성을 가진다.Briefly looking at the configuration of the wet classifier disclosed in Figure 2, the soil mixture (5) obtained after the first crushing step (S2) continuously in the water tank 20 through the hopper 11, the soil mixture (5) Is submerged in water and has a specific gravity of less than 1 foreign matter has a configuration that is floating on the water surface in the sump (20).

따라서, 수중으로 침하되는 토사혼합골재(5)는 호퍼(11) 하측의 집수조(20)내에 설치된 토사혼합골재 배출수단(12)에 의해 외측으로 배출시킬 수 있으며, 집수조(20)의 수면위로 부유된 이물질은 집수조(20)의 수면 위에서 집수조(20)의 외측으로 설치된 이물질 배출수단(13)에 의해 집수조(20)의 외측으로 배출시키는 구성을 가진다.Therefore, the soil mixture aggregate 5 that is settled in the water can be discharged to the outside by the soil mixture aggregate discharge means 12 installed in the water tank 20 of the hopper 11 lower side, floating on the water surface of the water tank 20 The foreign matter is discharged to the outside of the collection tank 20 by the foreign matter discharge means 13 installed to the outside of the collection tank 20 on the water surface of the collection tank (20).

상기 종래부터 시행되어온 선행기술은 각종 건축 폐기물에 포함되어 있는 불순물을 분리하여 순수한 폐콘크리트에 의한 골재의 생산이 효과적으로 이루어질 수 있다는 장점이 어느 정도 확보되어 있으나, 불순물이 제거되는 과정에서 배출되는 배출수의 정수처리 문제 등의 후속 처리과정이 수반되며, 배출수의 정수처리가 원활하지 않을 경우에는 배출수에 의한 2차 환경오염이 발생하는 등의 문제점이 발생되며, 집수조의 내부에서 부유 불순물을 분리하는 효율이 기대치 보다 낮은 편이며, 이물질이 분류되는 과정에서 모래를 별도로 회수하여 재활용하지 않고 흙과 혼합된 상태로 그대로 폐기되는 문제점을 내포하고 있다.The prior art that has been practiced in the prior art has been secured to some extent that the production of aggregates by pure waste concrete can be effectively achieved by separating impurities contained in various construction wastes, but the wastewater discharged in the process of removing impurities Subsequent treatments, such as water treatment problems, are involved, and if the wastewater treatment is not smooth, secondary environmental pollution occurs due to the discharged water, and the efficiency of separating the floating impurities in the collection tank is increased. It is lower than expected, and the problem is that sand is collected in the process of classifying foreign matters, and is discarded as it is mixed with soil without recycling.

또한, 동절기에는 집수조 내부의 물이 결빙되어 사용이 불가능한 단점이 있으며, 젖은 상태의 순환골재를 건조 후 적치해야 하는 문제가 있고, 각종 기계 장치가 집수조 내부에 설치됨으로써 부식 혹은 고장을 일으킬 우려가 높은 또 다른 문제점을 가지고 있다.In addition, there is a disadvantage that the water inside the sump can not be used in the winter season, which can not be used, there is a problem that must be accumulated after drying the circulating aggregate in the wet state, there is a high risk of causing corrosion or failure by installing various mechanical devices inside the sump I have another problem.

본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위해 발명된 것 으로서, 기존 건축물의 철거 시 발생하는 건축 폐기물을 순환골재로 사용하기 위해 가공되는 여러 공정 중, 골재의 분쇄공정 후 발생되는 이물질이 혼재된 토사 혼합골재가 컨베이어를 통해 원료투입호퍼로 유입될 시, 원료투입호퍼 하부에 토사 혼합골재를 균등하게 분배하기 위한 스크류 날개를 갖는 원료분배기가 설치되어 유입골재를 골고루 분산시켜 계단식 경사판 상부로 균등하게 배출시키도록 유도하고, 계단식 경사판은 진동을 갖는 다단 구조를 이루고 경사판 후부에는 송풍기가 설치되어 유입골재가 경사판을 경유하여 낙하 될 시 경사판 후면에서 낙하되는 토사 혼합골재에 강한 바람을 불어넣어 비중이 가벼운 비닐, 스티로폼, 섬유실 등 이물질과 토분을 먼저 제거시키고 순수 골재만을 진동스크린으로 이송시켜 진동스크린에서 순수골재만을 입도별로 분류시켜 양질의 순환골재를 얻을 수 있도록 함을 목적으로 한다.The present invention has been invented to solve the problems of the prior art as described above, the foreign matter generated after the crushing process of the aggregate of the various processes are processed to use the building waste generated during the demolition of the existing building as the circulation aggregate When mixed soil mixed aggregate enters the feed hopper through the conveyor, a raw material distributor having screw blades for equally distributing the soil mixed aggregate is installed at the bottom of the feed hopper to evenly distribute the incoming aggregate to the top of the stepped slope plate. Induced to discharge evenly, the stepped slope plate forms a multi-stage structure with vibration, and a blower is installed at the rear side of the slope plate to blow strong wind to the soil mixture aggregate that falls from the back of the slope plate when the incoming aggregate falls through the slope plate. When removing foreign substances and soil such as light vinyl, styrofoam, fiber thread By transferring only the high purity aggregates with vibrating screens that aims to achieve a high quality recycled aggregates was classified only by pure aggregate particle size in the vibrating screen.
