Description

폐레미콘의 골재선별 재활용장치 {Apparatus for Recovering Gravels and Sands from Waste Ready-Mixed Concrete}Waste Remicon Aggregate Screening Recycling Device {Apparatus for Recovering Gravels and Sands from Waste Ready-Mixed Concrete}

본 발명은 폐레미콘의 골재선별 재활용장치에 관한 것으로 특히 자갈과 모래 그리고 물을 효과적으로 분리하되 작업성을 향상하고 설치면적을 최소화 하는 한편, 양질의 재활용 골재를 얻고자 하는데 목적이 있다.The present invention relates to an apparatus for sorting aggregates of waste ready mixed concrete, in particular, to effectively separate gravel, sand and water, while improving workability and minimizing installation area, and to obtain high quality recycled aggregates.

레미콘은 주로 하천 등지에서 채취되는 골재가 80%정도 이며 이에 시멘트와 을 혼합하여 조성되고 있는바, 자원이 부족한 환경에서는 레미콘의 사용후 남는 폐레미콘을 재활용할 수 있는 수단이 절실히 요구된다. 일반적으로 레미콘을 현장납품 하거나 사용하고 남는 폐레미콘을 통상 폐기 처분함에 따라 자원의 낭비를 초래할 뿐 아니라 특히 환경을 오염시키는 폐단이 있다. 따라서 최근에는 폐레미콘을 재활용하기 위한 조치가 활발히 연구되고 있으나 대부분 과다한 설치비 및 유지보수비가 지출되고 있으며 특히 장치가 방만하여 설치면적을 많이 차지할 뿐 아니라 이로인한 설비 주변관리가 어려운 문제점이 지적되고 있다. 이와같은 종래의 폐레미콘 재활용장치는 도 3에서 나타내고 있다.The ready-mixed concrete is made up of 80% of the aggregates collected from rivers and the like, and is mixed with cement. Therefore, there is an urgent need for a means to recycle the waste ready-mixed concrete after the use of the ready-mixed concrete. In general, when the ready-to-use ready-to-use ready-mixed concrete ready to be disposed of and used, the waste-mixed concrete is not only causing waste of resources but also particularly polluting the environment. Therefore, in recent years, measures for recycling waste concrete are being actively researched, but most of the installation and maintenance costs are expended. In particular, it is pointed out that the equipment occupies a lot of the installation area due to the neglect of the equipment and it is difficult to manage the surroundings of the facility. Such a conventional ready-mixed concrete recycling device is shown in FIG.

도 3에서 나타내고 있는바와 같이 폐레미콘에서 자갈과 모래 그리고 물의 효과적인 분리수단으로 원형망체(200)는 기본적으로 사용되고 있으나 그 효과적인 구성은 미흡한 수단이다. 즉, 상기 원형망체(200)내의 중앙에는 스크류(210)가 설치되고 원형망체(200)의 입구는 폐레미콘을 투입하여 이송하는 폐레미콘이송부(100)와 연결된다. 원형망체(200)는 모래와 물만 빠질 수 있는 정도의 메쉬를 가지는바,원형망체(200)내로 이송된 폐레미콘중 자갈은 스크류(210)에 의해 상측으로 이동되고 물과 모래는 원형망체(200)를 통하여 저부의 1차슬러지탱크(300)로 유입된다. 스크류(210)에 의해 상측 이동한 자갈은 원형망체(200)의 출구를 빠져나와 이와 연접한 콘베어(400)에 의해 이송되면서 콘베어(400)의 말단 저부에 마련된 자갈회수탱크(500)에 수집된다. 이어서 1차슬러지탱크(300)에 유입된 물과 모래는 펌프(P1)에 의해 배관(600)을 통하여 스크류콘베어(700)로 투입되고 여기서 물은 다시 배관(610)을 통하여 2차슬러지탱크(310)로 낙하하고 모래는 상기 스크류콘베어(700 )에 의해 이송되어 모래회수탱크(800)에 수집된다. 또 2차슬러지탱크(310)에 유입된 물은 펌프(P2)에 의해 사이클론(CYCLONE)(900)으로 유입시키며 이때의 원심력으로 물에 잔존된 모래는 하방으로 낙하하여 스크류콘베어(700)를 통해 모래회수탱크 (800)로 유입되고 물(슬러지)은 배관(620)을 통하여 최종 3차슬러지탱크(320)로 회수되어 종말 처리하게 된다.As shown in FIG. 3, the circular mesh 200 is basically used as an effective separation means of gravel, sand and water in the ready-mixed concrete, but its effective configuration is insufficient. That is, the screw 210 is installed in the center of the circular mesh 200 and the inlet of the circular mesh 200 is connected to the waste ready-mixed concrete conveying unit 100 to feed the closed ready-mixed concrete. The circular mesh 200 has a mesh that can only drain the sand and water bar, the gravel of the waste ready-mixed concrete transported into the circular mesh 200 is moved upwards by the screw 210 and the water and sand is circular mesh 200 Through the bottom is introduced into the primary sludge tank 300. The gravel moved upward by the screw 210 is collected in the gravel recovery tank 500 provided at the end bottom of the conveyor 400 while passing through the exit of the circular mesh 200 and transported by the conveyor 400 connected thereto. . Subsequently, water and sand introduced into the primary sludge tank 300 are introduced into the screw conveyor 700 through the pipe 600 by the pump P1, and the water is again supplied through the pipe 610 to the secondary sludge tank ( Dropped to 310 and the sand is transported by the screw conveyor 700 is collected in the sand recovery tank (800). In addition, the water introduced into the secondary sludge tank 310 is introduced into the cyclone (CYCLONE) (900) by the pump (P2) and the sand remaining in the water by the centrifugal force falls downwards through the screw conveyor 700 Water (sludge) is introduced into the sand recovery tank 800 is recovered to the final tertiary sludge tank 320 through the pipe 620 and the end treatment.

이와같은 종래의 장치는 자갈을 먼저 선별한 다음, 물과 모래를 다시 이송하여 모래를 선별하고 다시 물을 이송하여 물에 잔존된 모래를 다시 걸러는 등 자갈과 모래의 분리공정이 별도로 수행됨에 따라 설치면적이 과다하고 작업성이 크게 떨어질 뿐 아니라 설치비 및 유지관리비가 많이 소요되게 되며 특히 탈수가 불량하여 물기를 많이 함유함에 따라 자갈 및 모래에 잔재된 시멘트에 의해 재활용 골재의 질을 저하시키고 있다.Such a conventional device is to separate the gravel and sand, such as sorting the gravel first, and then transfer the water and sand again to screen the sand and transfer the water again to filter the remaining sand in the water as the separation process of the gravel and sand is performed separately The installation area is excessive and the workability is greatly reduced, and the installation and maintenance costs are high. In particular, as the dehydration is poor, it contains a lot of water, thereby degrading the quality of recycled aggregates by the cement remaining in the gravel and sand.

본 발명은 상기한 제반 문제점을 고려하여 설비의 설치면적을 크게 축소하고 자갈 및 모래의 동시선별로 인한 작업성의 향상 그리고 이와 관련된 구성의 간소화를 제공하고자 하며 특히 선별된 골재의 함수량을 저하시켜 양질의 재활용 골재를 제공하고자 한다. 따라서 본 발명은 메쉬가 다른 스크린 망체를 상하로 구성하여 자갈과 모래가 상하 메쉬에 의해 동시에 선별되며 특히 스크린 망체는 진동모터에 의해 전방대각선 방향으로 진동하는 진동함체에 설치 함으로써 선별된 골재의 용이한 이송과 함께 효과적인 탈수가 이루어 지도록 한다.The present invention considerably reduces the installation area of the facility in consideration of the above-mentioned problems, to improve the workability due to the simultaneous line of gravel and sand, and to provide a simplification of the related configuration, in particular to lower the water content of the selected aggregates To provide recycled aggregates. Therefore, in the present invention, screen meshes having different meshes are formed up and down, and gravel and sand are simultaneously selected by the upper and lower meshes. In particular, the screen meshes are installed on the vibrating enclosure vibrating in the forward diagonal direction by the vibration motor. Ensure effective dehydration with transfer.

페레미콘이송부(10)와, 선별된 자갈 및 모래를 이송하는 콘베어(20)(21), 그리고 1차슬러지탱크(30)의 펌프(P) 및 2차슬러지탱크(40)를 각각의 배관(31)(41)으로 사이클론(50)과 연결하여된 통상의 것에 있어서, 폐레미콘이송부(10)와 콘베어( 20)(21)사이에는 저부 고정판(61)에 스프링(S)으로 연동되어 상부의 진동모터(M)로 진동되는 진동함체(60)를 구성하고 진동함체(60)내에는 상향 경사진 세공의 스크린망체(62) 및 미세공의 스크린망체(63)를 상,하로 설치하는 한편, 상기 콘베어(20)( 21)는 그 일단을 세공 및 미세공의 스크린망체(62)(63)말단 저부에 위치하면서 상,하로 구성하여된 구조이다. 그리고 1차슬러지탱크(30)의 내벽 상,하단에는 펌프(P)와 전기적으로 연동된 레벨스위치(SW1)(SW2)를 구성하여 유입된 물의 수위에 따라 펌프(P)가 가동 또는 중지하도록 한다.The fermicon transfer unit 10, the conveyor 20 and 21 for transferring the sorted gravel and sand, and the pump (P) and the secondary sludge tank 40 of the primary sludge tank 30, respectively, piping In the conventional thing connected to the cyclone 50 by (31) (41), between the waste concrete delivery unit 10 and the conveyor (20) (21) is interlocked with a spring (S) to the bottom fixing plate (61) A vibrating enclosure 60 is formed to be vibrated by the upper vibration motor M. In the vibrating enclosure 60, the screen mesh 62 of the upwardly inclined pores and the screen mesh 63 of the micropores are installed up and down. On the other hand, the conveyor (20) (21) is a structure consisting of up and down, one end is located at the bottom end of the screen mesh 62 (63) of the pores and fine pores. In addition, the upper and lower inner walls of the primary sludge tank 30 form a level switch SW1 (SW2) electrically connected to the pump P to allow the pump P to be started or stopped according to the level of water introduced. .

도면부호중 (70)은 자갈수집함, (71)은 모래수집함을 나타내며 진동함체(60)는 이와관련된 각 구성부분과 상호 연통구조를 취하고 있다. 또 세공의 스크린망체 (62)는 5mm 정도의 메쉬를 가지며 미세공의 스크린망체(63)는 약 1mm의 메쉬를 갖는다.Reference numeral 70 denotes a gravel collecting box, 71 denotes a sand collecting box, and the vibrating enclosure 60 has a mutual communication structure with each of the related components. The screen mesh 62 of the pores has a mesh of about 5 mm, and the screen mesh 63 of the fine pores has a mesh of about 1 mm.

페레미콘은 통상의 방법으로 폐레미콘이송부(10)에 투입되어 이송되며 이와같이 이송되는 폐레미콘은 진동함체(60)내로 투입되면서 세공의 스크린망체(62)상면에 유입되고 이때 유입된 폐레미콘중 자갈은 세공의 스크린망체(62)에 걸러지고 모래와 물은 이를 통과하게 되며 이어 그 저부의 미세공의 스크린망체(63)에서 모래는 걸러지고 물은 빠져나와 1차슬러지탱크(30)로 낙하한다. 한편, 상기 진동함체 (60)는 사방저면이 고정판(61)의 사방 모서리와 스프링(S)으로 연동되어 있어 충격에 의해 심하게 요동되는 구조이다. 따라서 이는 진동함체(60)상면에 장착된 진동모터(M)의 작동에 의해 심하게 진동되는바, 특히 본 발명에서 사용되는 진동모터(M )는 상향 대각선방향으로 진동을 이루는 모터를 사용함에 따라 진동함체(60)는 골재가 진행하는 방향으로 그리고 상향의 대각선 방향으로 진동을 하게 되므로 그 내측에 설치된 세공 및 미세공의 스크린망체(62)(63)도 상향 대각선 방향으로 진동하게 된다. 따라서 세공의 스크린망체(62)에 걸러진 자갈 및 상기 세공의 스크린망체 (62)를 통과하여 미세공의 스크린망체(63)에 걸러진 모래는 상기 각 스크린망체(62 )(63)가 비록 상향으로 경사지게 구성되어 있다 하더라도 상향의 대각선 방향으로 가해지는 진동방향에 의해 자갈 및 모래를 그 진행방향으로 밀어주는 작용을 하므로 자갈 및 모래는 일측 콘베어(20)(21)쪽으로 어려움없이 이동한다.The ferreticon is introduced into the waste ready-mixed concrete delivery unit 10 in a conventional manner, and the waste ready-mixed concrete is transferred into the vibrating enclosure 60 while being introduced into the upper surface of the screen mesh 62 of the pores. The gravel is filtered by the screen mesh 62 of the pores, and sand and water pass through it, and the sand is filtered out of the screen mesh 63 of the micropores at the bottom thereof, and water is released and falls into the primary sludge tank 30. do. On the other hand, the vibrating enclosure 60 is a structure in which the four sides of the bottom of the fixed plate 61 is interlocked with the spring (S) severely shaken by the impact. Therefore, this is severely vibrated by the operation of the vibration motor (M) mounted on the upper surface of the vibration enclosure 60, in particular the vibration motor (M) used in the present invention is vibrated by using a motor to make the vibration in the upward diagonal direction The enclosure 60 vibrates in the direction in which the aggregate proceeds and in the upward diagonal direction, so that the screen nets 62 and 63 of the pores and micropores installed therein also vibrate in the upward diagonal direction. Thus, the gravel filtered through the screen mesh 62 of the pores and the sand filtered through the screen mesh 63 of the micropores through the screen mesh 62 of the pores are inclined upwards even though the screen meshes 62 and 63 are upwardly inclined. Even if it is configured to act to push the gravel and sand in the traveling direction by the vibration direction applied in the diagonal direction upward, the gravel and sand moves to one side conveyor (20, 21) without difficulty.

본 발명은 이와같이 메쉬가 다른 각각의 스크린망체(62)(63)를 진동함체(60)내에 상,하로 구성함으로써 유입된 폐레미콘은 그 자갈과 모래가 동시에 선별되게 되며 특히 진동에 의해 골재가 함유하고 있는 물기가 쉽게 탈리되며 이와함께 각 스크린망체(62)(63)가 상향 경사지게 구성되어 있으므로 탈수 더욱 가중된다. 즉, 본 발명은 스크린망체(62)(63)의 상향 경사각 그리고 진동이 복합적으로 작용하여 우수한 탈수효과를 가져옴에 따라 골재의 함수율을 극히 저하시켜 양질의 재활용 골재를 제공하게 되는 것이다.According to the present invention, the screened concretes 62 and 63 having different meshes as described above are disposed up and down in the vibrating enclosure 60 so that the waste concrete can be simultaneously screened with gravel and sand. Water is easily removed and with this, each screen mesh 62, 63 is configured to be inclined upwards, so that dehydration is further increased. That is, the present invention is to provide a high-quality recycled aggregate by lowering the moisture content of the aggregate as the upward inclination angle and vibration of the screen net 62 (63) acts in combination to bring excellent dehydration effect.

모래는 세공의 스크린망체(62)에서 단번에 통과되지는 않으나 자갈과 함께 이송되는 도중 그리고 진동에 의해 쉽게 저부로 쳐지면서 일측 콘베어(20)(21)에 이르기 전에 모두 통과한다. 이와같이 이송되는 자잘 및 모래는 이와 연접한 각각의 콘베어(20)(21)로 동시에 낙하하게 되고 이어 콘베어(20)(21)의 구동에 의해 일측에 마련된 자갈 및 모래수집함(70)(71)에 유입되게 된다. 여기에서도 본 발명은 종래와는 달리 상기 콘베어(20)(21)가 상,하로 구성되어 선별,이송된 자갈과 모래를 동시에 인수하여 동시에 회수되도록 함으로써 작업성의 향상은 물론 설비 면적을 크게 줄이고 있다.The sand does not pass at once in the screen mesh 62 of the pore but passes all the way to the one side conveyors 20 and 21 while being transported together with the gravel and struck easily to the bottom by vibration. The jalja and sand transported in this way are simultaneously dropped to each conveyor (20) (21) connected to it, and then gravel and sand collection box (70) (71) provided on one side by driving the conveyor (20) (21). Will flow in. Here, the present invention, unlike the prior art, the conveyor (20, 21) is composed of up and down, taking over the gravel and sand selected and transferred at the same time to be recovered at the same time to improve the workability and significantly reduce the installation area.

한편, 1차슬러지탱크(30)에 유입된 슬러지를 포함한 물은 펌프(M)의 가동으로 배관(31)을 통하여 사이클론(50)으로 이송되고 이송된 물은 원심력에 의해 상부의 배관(41)을 통하여 2차슬러지탱크(40)로 이송되며 이때 물속에 잔존된 모래는 낙하하여 진동함체(60)내로 재투입함으로써 골재의 재활용량을 극대화 하게 된다. 물론 이와같은 사이클론(50)을 이용한 모래의 재수거 수단은 범용의 기술을 본 발명과 관련구성으로 하고 있기는 하나, 본 발명에서는 상기 펌프(P)의 작동을 필요시에만 작동하도록 하고 있다. 즉, 본 발명은 1차슬러지탱크(30)의 내벽 상,하단에 상기 펌프(P)와 전기적으로 연동된 레벨스위치(SW1)(SW2)를 구성하고 있는바, 1차슬러지탱크(30)내에 슬러지를 포함한 물이 적정 수위에 이르면 상부의 레벨스위치( SW1)가 이를 감지하여 펌프(P)를 작동시켜 물을 상부의 사이클론(50)으로 이송시키는 한편, 수위가 점점낮아져 바닥에 근접하게 되면 이때에는 저부의 레벨스위치(SW 2)가 이를 감지하여 펌프(P)의 가동을 중지시킨다. 이는 종래 펌프를 지속적으로 가동시키거나 수동으로 펌프를 가동 또는 중단시키는 것에 비하여 전력 및 인력의 낭비를 줄이게 됨은 물론 작업성을 향상시키는데 크게 도움이 된다.On the other hand, the water including the sludge introduced into the primary sludge tank 30 is transferred to the cyclone 50 through the pipe 31 by the operation of the pump (M) and the transferred water is piped to the upper portion by the centrifugal force (41) It is transferred to the secondary sludge tank 40 through the sand remaining in the water is dropped and re-introduced into the vibrating enclosure 60 to maximize the recycling amount of aggregate. Of course, although the sand re-collection means using the cyclone 50 is a general-purpose technology related to the present invention, the present invention is to operate the pump (P) only when necessary. That is, the present invention constitutes a level switch (SW1) (SW2) electrically connected to the pump (P) above and below the inner wall of the primary sludge tank (30), in the primary sludge tank (30). When the water including the sludge reaches the appropriate level, the upper level switch SW1 detects this and operates the pump P to transfer the water to the upper cyclone 50, while the water level becomes lower and close to the bottom. In the bottom level switch (SW 2) detects this to stop the operation of the pump (P). This greatly helps to improve workability as well as reducing waste of power and manpower as compared to continuously operating the pump or manually starting or stopping the pump.
