Description
본발명은 건축 폐기물을 파쇄한 재활용 석분의 이물질을 제거하여 레미콘용으로 사용가능한 품질의 모래를 선별해 내도록 하는 재활용 모래 선별기에 관한 것이다.The present invention relates to a recycled sand sorter to remove the foreign matter of the recycled stone powder crushed construction waste to sort out the sand of the quality available for ready-mixed concrete.
건축폐기물을 파쇄한 석분은 도로의 다짐용이나 복토용으로 사용되고, 극히 제한적으로 일부분이 건축용으로 재활용되고 있는 실정으로, 파쇄된 석분을 재활용하지 못하는 이유는 석분에 포함된 이물질을 효과적으로 제거해 내지 못하여 석분에 토사나 미분사 및 철사나 나무토막 등의 이물질이 섞이게 되므로 건축용 자재로 재활용하지 못하는 것이다.Stone powder crushed construction waste is used for road compaction or cover, and only part of it is recycled for construction purposes. The reason why the crushed stone powder cannot be recycled is because it cannot effectively remove foreign substances contained in the stone powder. Soil, fine spray, and foreign substances such as wire and wood chips are mixed and thus cannot be recycled as a building material.
특히, 레미콘용으로 사용되는 모래는 강에서 채취하는 것을 사용하는 것이 좋으나, 강에서 채취하는 모래의 양이 제한적이고 또한 채취장소에서 사용장소까지 운반하는데 상당한 운반비용이 소용되므로 사용이 제한적일 수밖에 없다.In particular, the sand used for ready-mixed concrete is preferably used to collect from the river, but the use of the sand is limited because the amount of sand collected from the river is limited, and a considerable transportation cost is used to transport it from the collection place to the place of use.
따라서, 건축 폐기물을 파쇄하여 얻어지는 석분을 이용하려고 하고 있으나, 석분에는 상기된 바와 같이 이물질이 혼합되어 있어 정선된 재료만을 사용하는 레미콘에는 사용할 수 없는 것이었다.Therefore, while attempting to use the stone powder obtained by crushing the building waste, it was not possible to use the ready-mixed concrete using only selected materials because the foreign matter is mixed in the stone powder as described above.
그러나, 석분이라도 깨끗이 세척하여 이물질이 완전히 제거된 상태라면 사용할 수 있는 것으로, 기존에는 석분으로부터 이물질을 제거시킨 모래를 얻을 수 없었다.However, it is possible to use even if the dust is completely removed by cleaning the stone dust, conventionally, it was not possible to obtain sand from which foreign substances were removed from the stone powder.
본발명은 건축 폐자재를 분쇄하여 얻어진 석분을 물로 세척하는 한편 석분에 섞인 이물질을 깨끗이 제거하여 레미콘 모래로 사용할 수 있도록 하는 것이다.The present invention is to wash the stone powder obtained by pulverizing the construction waste materials with water and to remove foreign substances mixed in the stone powder to be used as ready-mixed sand.
즉 본발명은 석분으로부터 미분과 이물질을 제거하여 깨끗한 모래를 선별해내도록 하는 것이다.That is, the present invention is to remove the fine powder and foreign matter from the stone powder to sort out the clean sand.
이러한 본발명은 수평으로 놓여져 서서히 회전하는 회전원통의 내부에 일정 높이의 이송스크류를 여러줄로 설치하고, 상기 회전원통에는 석분을 중간부위에 투입시키는 한편 물을 공급하며, 상기 회전원통에서 흘러나온 미분과 오수는 폐수처리조로 흐르게 하고, 상기 회전원통의 배출구에는 원뿔형 배출콘을 설치하며, 상기 배출콘의 외면과 회전원통의 내면 사이에는 다수개의 배출날개를 설치하므로써 이루어지는 것으로, 상기 회전원통에 투입된 석분은 회전원통에서 물에 잠김 채로 회전하여 깨끗이 세척되고 세척된 모래는 배출날개에 의해 배출콘에서 배출구로 배출되게 하는 것이다.The present invention is installed horizontally in a rotating cylinder of horizontal rotation is installed in a plurality of rows of a fixed screw of a certain height, the rotation cylinder is supplied with water while feeding the stone powder in the middle portion, flowed out of the rotating cylinder The fine powder and sewage flow to the wastewater treatment tank, and the conical discharge cone is installed at the outlet of the rotary cylinder, and a plurality of discharge vanes are installed between the outer surface of the discharge cone and the inner surface of the rotary cylinder.

이러한 구성의 본발명에서 회전원통(10)의 내부에는 석분 투입함(6)에서 콘베어 벨트(5)를 타고 건축 폐기물을 분쇄한 석분이 공급되게 하고, 물공급구(8)로는 물이 공급되게 하며, 회전원통(10)의 투입구(10a)에서 넘친 물은 집수조(14)에 모아지게 된다.In the present invention of the configuration of the rotary cylinder 10 in the stone powder input (6) in the conveyor belt (5) to be supplied with the powdered stone powder pulverized building waste, and the water supply port (8) to supply water , The overflowed water from the inlet (10a) of the rotary cylinder 10 is collected in the sump (14).
그리고 회전원통(10)은 기어드 모터(3)를 구동시키면 서서히 회전하게 된다.And the rotating cylinder 10 is rotated slowly when driving the geared motor (3).
이같이 회전원통(10)을 회전시킨 상태에서 석분과 물을 공급하면 석분은 회전원통(10)의 중간부에 떨어져 회전원통(10)의 내면에 설치된 이송스크류(12)에 의해 배출구(13)쪽으로 이동되며, 이때 석분은 물에 잠김 상태이므로 이물질 및 미분 등은 투입구(10a)쪽으로 흘러나오게 되고, 이물질 및 미분이 제거된 모래는 이송스크류(12)를 타고 배출구(13)쪽으로 이동하게 된다.When the powder and water are supplied in the state in which the rotary cylinder 10 is rotated as described above, the stone powder falls to the middle portion of the rotary cylinder 10 to the discharge port 13 by a transfer screw 12 installed on the inner surface of the rotary cylinder 10. In this case, the stone powder is immersed in water so that foreign matters and fine powder flow out toward the inlet 10a, and the sand from which the foreign matter and fine powder is removed is moved to the discharge port 13 by the transfer screw 12.
여기서 석분에 포함된 이물질 및 미분 등은 물에 부유된 상태로 투입구(10a)로 넘쳐 흘러내리고, 물에 세척된 깨끗한 모래는 비중이 무거워 이송스크류(12)를 타고 배출구(13)쪽으로 이송되는 것이다.Here, the foreign matter and fine powder contained in the stone powder flows down into the inlet 10a while floating in water, and the clean sand washed in the water is heavy and is conveyed toward the outlet 13 on the transport screw 12. .
회전원통(10)의 내부에서 석분을 세척한 물은 투입구(10a)로 흘러내려 집수조(14)로 모아진 후 폐수처리조로 이동되어 정화된 후 다시 물공급구(8)로 이동시켜 물을 재활용하도록 한다.Water washed in the interior of the rotary cylinder 10 flows into the inlet (10a) is collected in the collection tank (14) and then moved to the waste water treatment tank to be purified and moved back to the water supply port (8) to recycle the water. .
한편 회전원통(10)의 내면에 설치된 이송스크류(12)는 등간격으로 6~12줄을 설치하되, 배출날개(21)에 상기 이송스크류(12)의 끝단부가 위치되게 하고, 배출날개(21)가 6개 일 경우 이송스크류(12)는 12개가 바람직하며, 상기 배출날개(21)와 이송스크류(12)의 수는 설계변경에 따라 달리 형성할 수 있다.Meanwhile, the transfer screw 12 installed on the inner surface of the rotating cylinder 10 has 6 to 12 rows installed at equal intervals, so that the end of the transfer screw 12 is positioned on the discharge blade 21, and the discharge blade 21 In case of 6), the number of the feeding screws 12 is preferably 12, and the number of the discharge blades 21 and the feeding screws 12 may be formed differently according to the design change.
회전원통(10)에서 석분이 세척되어 이물질과 미분등이 제거된 모래는 회전하는 이송스크류(12)를 타고 배출콘(20)쪽으로 이송되어 배출날개(21)사이로 이동되는 것으로, 도 7 과 같이 상기 배출날개(21)와 배출날개(21)사이에는 두개의 이송스크류(12)가 배치되어 두개의 이송스크류(12)에 의해 이송된 모래는 하나의 배출날개(21)안으로 모아지게 된다.The sand from which the dust is removed from the rotary cylinder 10 and foreign matters and fine powders are removed is transferred to the discharge cone 20 by the rotating transfer screw 12 and is moved between the discharge blades 21, as shown in FIG. 7. Two transfer screws 12 are disposed between the discharge blades 21 and the discharge blades 21 so that sand transferred by the two transfer screws 12 is collected into one discharge blade 21.
상기 배출날개(21)는 회전원통(10) 및 배출콘(20)과 함께 회전되므로 배출날개(21)안에 모아진 모래를 끌고 올라가게 되며, 이때 배출날개(21)에 형성된 배출망(22)에 의해 물은 빠지고 모래만 끌고 올라가게 된다.The discharge blade 21 is rotated together with the rotary cylinder 10 and the discharge cone 20, so that the sand collected in the discharge blade 21 is pulled up, at this time to the discharge network 22 formed on the discharge blade 21 By this, the water is drained and only sand is raised.
세척된 모래의 배출은 연속적으로 행해지는 것으로, 배출콘(20)의 하측부에서 배출날개(21)가 회전하여 모래를 끌고 올라가면 모래는 배출날개(21)가 배출콘(20)의 상측부를 향할수록 배출콘(20)의 꼭지부분 쪽으로 흘러내리게 되며, 배출날개(21)가 배출콘(20)의 상측부에 도달하면 모래는 배출콘(20)의 경사진 외면을 타고 흘러내려 배출구(13)를 통해 배출된다.The discharge of the washed sand is carried out continuously, when the discharge blade 21 is rotated at the lower side of the discharge cone 20 to pull the sand up, the sand is discharged blade 21 toward the upper side of the discharge cone (20) As it flows down toward the top of the discharge cone 20, the discharge wing 21 reaches the upper portion of the discharge cone 20, sand flows down the inclined outer surface of the discharge cone 20 to discharge the outlet 13 Is discharged through.
이는 원뿔형상을 가지는 배출콘(20)의 꼭지부분이 배출구(13)쪽을 향하여 설치되므로써 배출콘(20)의 상측부 외면이 배출구(13)쪽으로 경사져 배출날개(21)에 의해 끌려 올라온 모래가 배출콘(20)의 경사진 외면을 타고 자연적으로 흘러내려 배출되는 것이다.This is because the top of the discharge cone 20 having a conical shape is installed toward the discharge port 13 side, the outer surface of the upper side of the discharge cone 20 is inclined toward the discharge port 13 so that the sand drawn up by the discharge wing 21 The inclined outer surface of the discharge cone 20 is naturally discharged and discharged.
이러한 본발명은 모래가 배출콘(20)과 배출날개(21)를 타고 올라갈 때 배출날개(21)에 형성된 배출망(22)에 의해 물은 빠지고 모래만 배출구(13)로 배출되므로써 건조가 용이하며, 배출구(13)를 통해 배출된 모래는 콘베어벨트(15)를 타고 모아져 레미콘용 골재로 사용된다.The present invention is easy to dry because the sand is drained by the discharge net 22 formed in the discharge blade 21 and only the sand is discharged to the discharge port 13 when the sand rides up the discharge cone 20 and the discharge wing 21. And, the sand discharged through the discharge port 13 is collected on the conveyor belt 15 is used as aggregate for ready-mixed concrete.
본발명은 건축폐기물을 분쇄시킨 석분에서 이물질이나 미분을 제거시켜 레미콘용으로 사용가능한 품질의 모래를 선별하는 것으로, 물로 세척하여 이물질과 미분을 제거하되, 상기 물은 폐수처리조에서 정화처리하여 재활용 하고, 석분에서 분리된 모래는 깨끗이 세척되어 배출되므로 레미콘용 골재로 사용할 수 있다.The present invention is to remove the foreign matter or fine powder from the stone powder crushed the construction waste, and to select the sand of the quality available for ready-mixed concrete, wash with water to remove the foreign matter and fine powder, the water is purified and recycled in the waste water treatment tank And, the sand separated from the stone powder can be used as the aggregate for ready-mixed concrete because it is washed and discharged.
따라서 레미콘용 골재를 구하는 골재난을 해소할 수 있으며, 건축폐기물을 재활용하여 자원의 낭비를 줄이는 효과가 있는 것이다.Therefore, it is possible to solve the aggregate disaster for obtaining ready-mixed concrete aggregate, and to reduce the waste of resources by recycling construction waste.
