Description

재생골재 선별기{Sorting machine of reclaimed stones}Recycled Aggregate Separator {Sorting machine of reclaimed stones}

본 발명은 건설폐기물을 재생 사용하기 위한 재생골재 선별기에 관한 것으로, 골재의 입경에 따라서 분리하여 선별할 수 있고 젖은 골재의 건조와 혼합이 용이하여 다량의 골재의 선별을 효율적으로 할 수 있는 재생골재 선별기에 관한 것이다.The present invention relates to a recycled aggregate sorting machine for regenerating construction wastes, which can be separated and sorted according to the particle size of the aggregate, and is easy to dry and mix wet aggregates to efficiently select a large amount of aggregates. It is about a sorter.

최근 대도시 주변에서 건설폐기물의 일종인 폐콘크리트는 도시재개발과 건물의 노후화 및 기능저하에 의한 건물의 해체가 증가함에 따라 다량으로 배출되고 있다. 또한 막대한 양의 폐콘크리트가 재활용되지 못하고 매립 및 불법투기 등과 같이 부적절하게 처리됨으로써 환경오염 문제를 발생시키고 있다. 따라서, 다량으로 발생되는 폐콘크리트를 재활용하는 것은 자원 및 에너지 절약 측면뿐만 아니라 환경보호 측면에서도 그 중요도가 증가하고 있다.In recent years, waste concrete, which is a kind of construction waste around large cities, is being discharged in large quantities due to the increase of dismantling of buildings due to urban redevelopment, aging and deterioration of buildings. In addition, a huge amount of waste concrete is not recycled and improperly disposed of, such as landfilling and illegal dumping, causing environmental pollution problems. Therefore, recycling of a large amount of waste concrete is increasing in importance not only in terms of resource and energy saving but also in environmental protection.

그러나 막대한 양으로 발생되는 폐콘크리트의 대부분이 재활용 및 재사용이 미비한 실정이다. 하지만 폐콘크리트는 유효 적절한 기술처리 및 고도의 재활용시스템이 이루어진다면 도로의 기층·보조기층재, 콘크리트용 골재 및 우수한 도시기반 형성재로 재활용될 수 있을 것이다.However, most of the waste concrete generated in a huge amount is not recycled and reused. However, waste concrete can be recycled into road substrates and subsidiary materials, concrete aggregates and excellent urban foundations if effective technical processing and advanced recycling systems are in place.

폐콘크리트의 재활용은 폐콘크리트를 파쇄하고 입경별로 분류하고 토분, 금속류, 부유물질 등을 제거시키며 재생골재를 소요입경별로 생산하는 시스템으로 이루어진다. 이 중에서 파쇄된 폐콘크리트를 입경별로 분류하는 과정에서 쓰이는 것이 재생골재 선별기이다.The recycling of waste concrete consists of a system of crushing waste concrete, classifying it by particle size, removing soil, metals, suspended solids, etc. and producing recycled aggregates by required particle size. Among them, the recycled aggregate sorter is used in the process of classifying the crushed waste concrete by particle size.

종래의 재생골재 선별기는 회전드럼에 연결된 투입구를 통해 분쇄된 폐콘크리트가 투입되면 토출공이 뚫린 회전드럼이 회전하면서 입경이 작은 골재가 토출공을 통과하여 호퍼로 배출되고, 입경이 큰 골재는 회전드럼의 개구부를 통해 떨어지게 되어 있었다.In the conventional recycled aggregate sorter, when the crushed waste concrete is put through the inlet connected to the rotating drum, the rotating drum with the discharge hole is rotated, and the aggregate having a small particle size is discharged through the discharge hole to the hopper, and the aggregate having the large particle diameter is the rotating drum. It was supposed to fall through the opening.

그러나 종래의 재생골재 선별기는 회전드럼의 토출공의 크기가 한 가지 종류밖에 없어서 한번에 한 가지 입경 이하의 골재만 선별할 수밖에 없다는 문제점이있었다.However, the conventional recycled aggregate sorter has a problem that only one type of aggregate having a particle size of less than one particle at a time is selected because only one type of discharge hole of the rotating drum is present.

또한, 일반적으로 폐콘크리트는 젖은 상태여서 회전드럼이 회전하여도 골재가 덩어리로부터 쉽게 분리되지 않는 문제점도 있었다.In addition, in general, the waste concrete has a problem that the aggregate is not easily separated from the lump even if the rotating drum rotates.

또한, 회전드럼이 회전할 때 폐콘크리트가 중력에 의해 회전드럼의 바닥부에 집중되므로, 폐콘크리트가 회전드럼 내에 골고루 위치하게 하여 골재의 선별을 효율적으로 할 수 없다는 문제점도 있었다.In addition, since the waste concrete is concentrated at the bottom of the rotating drum by gravity when the rotating drum is rotated, there is a problem that the waste concrete is evenly located in the rotating drum to effectively select the aggregate.

한편, 회전드럼의 외주면과 토출공에 이물질이 끼지 않게 하여 골재가 빠져나가기 용이하게 할 필요성도 있다.On the other hand, there is also a need to make the aggregate easy to escape by preventing foreign matter from being caught in the outer peripheral surface and the discharge hole of the rotating drum.

본 발명은 상기의 문제점을 해결하기 위하여, 한번의 작업으로 두 가지 이상의 입경을 갖는 골재를 선별할 수 있는 재생골재 선별기를 제공함을 목적으로 한다.In order to solve the above problems, an object of the present invention is to provide a recycled aggregate selector capable of selecting aggregate having two or more particle diameters in one operation.

또한, 본 발명은 골재가 젖은 폐콘크리트 덩어리로부터 쉽게 분리될 수 있도록 건조장치를 구비한 재생골재 선별기를 제공함을 목적으로 한다.It is also an object of the present invention to provide a recycled aggregate sorter having a drying device so that the aggregate can be easily separated from the wet waste concrete mass.

또한, 본 발명은 회전드럼이 회전할 때 폐콘크리트가 회전드럼 내에 골고루 위치하게 하여 다량의 골재를 효율적으로 선별할 수 있는 재생골재 선별기를 제공함을 목적으로 한다.In addition, an object of the present invention is to provide a recycled aggregate sorter capable of efficiently sorting a large amount of aggregate by placing the waste concrete evenly in the rotating drum when the rotating drum rotates.

또한, 본 발명은 회전드럼의 외주면과 토출공에 이물질이 끼지 않아 골재가 빠져나가기 용이한 재생골재 선별기를 제공함을 목적으로 한다.In addition, an object of the present invention is to provide a recycled aggregate selector that is easy to escape the aggregate because foreign matter is not caught in the outer peripheral surface and the discharge hole of the rotating drum.

도1은 본 발명의 일실시예에 따른 재생골재 선별기의 사시도를 나타낸다.1 is a perspective view of a recycled aggregate sorter according to an embodiment of the present invention.

도1을 참조하면, 본 발명의 일실시예에 따른 재생골재 선별기(10, 이하 '선별기'라 한다)는 회전드럼(100)과, 컨베이어(102)와, 제1호퍼(104) 및 제2호퍼(106)와, 건조장치(110)를 포함한다.Referring to Figure 1, the recycled aggregate sorter (10, hereinafter referred to as "selector") according to an embodiment of the present invention is a rotating drum 100, the conveyor 102, the first hopper 104 and the second The hopper 106 and the drying apparatus 110 are included.

회전드럼(100)은 투입되는 파쇄된 폐콘크리트의 골재를 회전력으로 분류한다. 회전드럼(100)은 원통형으로서 일정한 각도를 가지고 아래로 경사지게 설치되며, 상측은 파쇄된 폐콘크리트를 투입할 수 있도록 개구되어 있다.Rotating drum 100 classifies the aggregate of the crushed waste concrete is put into rotational force. The rotating drum 100 is cylindrical and is installed to be inclined downward at a predetermined angle, and the upper side thereof is opened to input the crushed waste concrete.

경사진 회전드럼(100)의 상측에는 파쇄된 폐콘크리트를 회전드럼(100)으로 투입하는 컨베이어(102)가 설치되어 있다. 회전드럼(100)의 하측은 회전드럼(100)의 토출공(122)이나 단위격자((126)를 통과할 수 없는 골재들이 밖으로 쏟아져 나오도록 개구되어 있다.At the upper side of the inclined rotating drum 100, a conveyor 102 for introducing the crushed waste concrete into the rotating drum 100 is installed. The lower side of the rotating drum 100 is open so that aggregates that cannot pass through the discharge hole 122 or the unit grid 126 of the rotating drum 100 flow out.

Supply torque to

회전드럼(100)의 아래에는 제1호퍼(104) 및 제2호퍼(106)가 설치되어 있다. 제1호퍼(104) 및 제2호퍼(106)는 호퍼받침대(108)를 통해 바닥에 고정시킨다.Below the rotating drum 100, the first hopper 104 and the second hopper 106 are provided. The first hopper 104 and the second hopper 106 are fixed to the floor through the hopper support 108.

선별기(10)는 폐콘크리트 덩어리를 건조시킬 수 있는 건조장치(110)를 포함한다. 건조장치(110)는 가열건조장치이며 지지대(112)에 의해 지지된다. 건조장치(110)는 열공급부(114)와 열판(116)과 열파이프(118)를 갖는다.The sorter 10 includes a drying device 110 capable of drying the waste concrete mass. The drying apparatus 110 is a heat drying apparatus and is supported by the support 112. The drying apparatus 110 has a heat supply unit 114, a hot plate 116, and a heat pipe 118.

열공급부(114)는 열파이프(118)로 전달될 열을 공급하며 열파이프(118)는 열판(116)에 연결되어 회전드럼(100) 쪽으로 향하도록 형성되어 있다. 열판(116)은 지지대(112) 위에 올려진다. 열판(116)에는 열파이프(118)에서 분지되는 다수개의 작은 파이프(도면상 미도시)들이 형성되어 있어 이들을 통해 열이 회전드럼(100) 쪽으로 확산된다. 건조장치(110)에서 나오는 열로 인해 폐콘크리트의 습기가 건조되어 폐콘크리트가 작은 덩어리로 떨어지기에 용이하다.The heat supply unit 114 supplies heat to be transferred to the heat pipe 118, and the heat pipe 118 is connected to the hot plate 116 to face the rotating drum 100. The hot plate 116 is mounted on the support 112. The hot plate 116 is formed with a plurality of small pipes (not shown) branched from the heat pipe 118 through which heat is diffused toward the rotating drum 100. Due to the heat from the drying apparatus 110, the moisture of the waste concrete is dried, and the waste concrete is easy to fall into small lumps.

회전드럼(100)은 타공철판부(120), 철망부(124), 혼합봉(128)을 포함한다.Rotating drum 100 includes a perforated iron plate 120, a wire mesh 124, the mixing rod 128.

타공철판부(120)는 직경 28mm의 토출공(122)이 다수개 천공된 철판으로서 입경이 28mm 이하인 골재가 통과하게 된다. 타공철판부(120)의 아래에는 통과한 골재를 받아내는 제1호퍼(104)가 설치되어 있다.The perforated iron plate part 120 is an iron plate having a plurality of discharge holes 122 having a diameter of 28 mm, and aggregates having a particle diameter of 28 mm or less pass therethrough. Under the perforated steel plate 120 is provided a first hopper 104 for receiving the aggregate passed.

철망부(124)는 길이 40mm의 단위격자(126)로 짜여진 철망으로서 입경이 40mm 이하인 골재가 통과하게 된다. 철망부(124)의 아래에는 통과한 골재를 받아내는 제2호퍼(106)가 설치되어 있다.The wire mesh 124 is a wire mesh woven with a unit grid 126 of 40 mm in length, and aggregates having a particle diameter of 40 mm or less pass therethrough. Under the wire mesh portion 124, a second hopper 106 for receiving the aggregate passed therethrough is provided.

회전드럼(100)의 내주면에는 다수개의 혼합봉(128)이 돌출되도록 형성되어 있다. 혼합봉(128)은 회전드럼(100) 내의 골재가 골고루 위치할 수 있도록 한다. 혼합봉(128)의 형태는 'ㄷ'자형 혼합봉(128a), 삼각형 혼합봉(128b), 평판 혼합봉(128c)의 세 가지가 있다.The inner circumferential surface of the rotating drum 100 is formed so that a plurality of mixing rods 128 protrude. The mixing rod 128 allows the aggregates in the rotating drum 100 to be evenly positioned. The mixing rod 128 has three types of 'c' shaped mixing rod 128a, triangular mixing rod 128b, and flat mixing rod 128c.

'ㄷ'자 형 혼합봉(128a)은 회전드럼(100)의 회전에 의해 하부로 내려오게되면 'ㄷ'자 형으로 상부가 열린 형태가 되고 골재가 혼합봉(128) 내로 들어가게 되며 계속되는 회전드럼(100)의 회전에 따라 혼합봉(128)이 상부로 이동하게 되면 혼합봉(128) 내의 골재가 회전드럼(100)의 바닥으로 떨어지게 된다.When the 'c' shaped mixing rod 128a is lowered by the rotation of the rotating drum 100, the upper portion is opened in a 'c' shape and the aggregate enters the mixing rod 128 and continues the rotating drum. When the mixing rod 128 is moved upward as the rotation of the 100, the aggregate in the mixing rod 128 falls to the bottom of the rotating drum 100.

삼각형 혼합봉(128b)과 평판 혼합봉(128c)도 회전드럼(100)의 하부에 위치할 때 골재를 들어올리고 상부에 위치할 때 골재를 떨어뜨려 회전드럼(100) 내부의 골재를 혼합한다.The triangular mixing rod 128b and the flat plate mixing rod 128c also raise aggregate when located at the bottom of the rotating drum 100 and drop aggregate when positioned at the top to mix aggregate inside the rotating drum 100.

이런 식으로 혼합봉(128)은 회전드럼(100) 내의 골재가 골고루 위치할 수 있게 하여 다량의 골재가 회전드럼(100)을 쉽게 빠져나갈 수 있도록 한다.In this way, the mixing rod 128 allows the aggregates in the rotating drum 100 to be evenly located so that a large amount of aggregate can easily exit the rotating drum 100.

회전드럼(100)의 외주면에는 브러쉬봉(130)이 형성되어 있다. 브러쉬봉(130)에는 회전드럼(100)의 외주면을 향하도록 브러쉬(132)가 형성되어 있어서 브러쉬봉(130)이 회전하면서 타공철판부(120)의 토출공(122)이나 철망부(124)의 단위격자(126)에 낀 이물질을 털어내고 이들이 회전드럼(100) 내부로 떨어져서 다시 선별될 수 있게 한다.Brush rod 130 is formed on the outer peripheral surface of the rotating drum (100). Brush rod 132 is formed in the brush rod 130 to face the outer circumferential surface of the rotating drum 100, so that the brush rod 130 rotates, the discharge hole 122 or the wire mesh portion 124 of the perforated steel sheet 120 The foreign substances caught in the unit grid 126 of the shake off and they can fall back into the rotating drum 100 to be screened again.

이하, 도면을 참조하여 본 발명에 따른 재생골재 선별기의 작동을 상세하게 설명한다.Hereinafter, the operation of the recycled aggregate sorter according to the present invention with reference to the drawings in detail.

도1을 참조하면, 파쇄된 폐콘크리트는 컨베이어(102)를 통해 회전드럼(100)의 내부로 투입된다. 투입된 폐콘크리트의 습기는 열공급부(114)에서 공급되어 열파이프(118)를 통해 회전드럼(100)으로 공급되는 열에 의해 건조되므로 덩어리가 떨어지기 쉽게 된다.Referring to FIG. 1, the crushed waste concrete is introduced into the rotating drum 100 through the conveyor 102.
