According to the present invention, disclosed is a device for screening recycled aggregate for concrete, which is improved to classify and screen recycled aggregate for concrete into oversize, undersize, high quality, and low quality when screening recycled aggregate for concrete of 25 mm or less by covering a part of the upper surface of a screening net through a net cover or a blocking cover.

Description

콘크리트용 순환골재 선별장치{Recycled aggregate screen device for concrete}Recycled aggregate screen device for concrete

본 발명은 콘크리트용 순환골재 선별장치에 관한 것으로, 더욱 상세하게는 선별망체의 상면 일부분을 망커버 또는 차단커버를 통해 덮어서 25mm 이하의 콘크리트용 순환골재를 선별할 때 오버사이즈, 언더사이즈, 고품질, 저품질을 구분해서 선별할 수 있도록 개선된 콘크리트용 순환골재 선별장치에 관한 것이다.The present invention relates to a recycling aggregate sorting device for concrete, and more particularly, when selecting recycled aggregate for concrete of 25 mm or less by covering a part of the upper surface of the sorting mesh through a mesh cover or blocking cover, oversize, undersize, high quality, It relates to a recycling aggregate sorting device for concrete that has been improved to be able to classify and sort low quality.

일반적으로 친환경적 측면 및 자원의 재활용 측면에서, 건설 및 건축 구조물의 해체시에 발생하는 건설폐기물은 매립되지 않고 소정의 장소로 수집된 후 중간처리공정을 통해 양질의 건설자원으로 재생산되고 있다. 특히, 건설폐기물의 순환골재는 도시와 지방 건축물의 재건축의 활성화에 따른 다량의 구조물 해체에 의해 그 활용도가 크게 증가하고 있다.In general, in terms of environment-friendliness and resource recycling, construction waste generated during construction and dismantling of building structures is not landfilled but is collected in a predetermined place and then reproduced as high-quality construction resources through an intermediate treatment process. In particular, the use of recycled aggregates from construction waste is greatly increasing due to the dismantling of large amounts of structures in accordance with the activation of reconstruction of urban and local buildings.

건설폐기물에서 순환골재를 생산하는 중간처리공정은 건설폐기물을 죠크라샤에서 1차 파쇄한 후, 콘크라샤나 임팩트크라샤 등에서 2차 또는 3차 파쇄한 다음, 선별장치를 통해 다양한 크기의 순환골재를 획득한다.In the intermediate treatment process to produce recycled aggregate from construction waste, the construction waste is first crushed in a jaw crusher, then secondarily or tertiarily crushed in a cone crusher or impact crusher, and then recycled aggregates of various sizes are separated through a sorting device. acquire

참고로, 대한민국 등록특허 제10-2174940호, 등록특허 제10-1892021호에는 선별장치의 일례가 개시되어 있다.For reference, Korean Patent No. 10-2174940 and Korean Patent No. 10-1892021 disclose an example of a sorting device.

그러나, 종래의 대부분의 선별장치는 선별망체가 전체적으로 동일한 사이즈의 망 구조를 갖기 때문에 고품질과 저품질의 순환골재가 함께 선별되는 문제점이 있다. 즉, 고품질은 골재 표면에 모르타르가 부착되어 있지 않은 순환골재이고 저품질은 골재 표면에 모르타르가 부착되어 사이즈가 불균일하며 비중이 가벼운 순환골재를 말하는데, 종래의 선별장치는 사이즈만으로 선별하기 때문에 고품질과 저품질을 구분해서 선별할 수 없는 문제점이 있다. However, most of the conventional sorting devices have a problem in that high-quality and low-quality recycled aggregates are sorted together because the sorting net body has a net structure of the same size as a whole. That is, high quality refers to recycled aggregate without mortar attached to the surface of the aggregate, and low quality refers to recycled aggregate with non-uniform size and light specific gravity because mortar is attached to the surface of the aggregate. There is a problem in that it cannot be separated and selected.

첨부된 도면들을 참조하여 본 발명에 대해 상세히 설명하면 다음과 같다. The present invention will be described in detail with reference to the accompanying drawings as follows.

도 1 내지 도 3을 참조하면, 본 발명에 따른 콘크리트용 순환골재 선별장치는 선별망체(100), 망커버(200), 차단커버(300)를 포함하여 구성된다.1 to 3 , the recycling aggregate sorting device for concrete according to the present invention is configured to include a sorting mesh body 100 , a mesh cover 200 , and a blocking cover 300 .

먼저, 선별망체(100)는 KS F 2527(콘크리트용 골재)에 적합한 25mm 이하의 콘크리트용 순환골재가 통과되어 선별되도록 전체적으로 동일한 사이즈의 망 구조를 갖고, 통상의 진동수단을 통해 진동 기능을 갖게 구성된다. 여기서, 진동수단은 통상의 기술을 적용하면 되기 때문에 상세한 설명은 생략하기로 한다.First, the screening mesh 100 has a mesh structure of the same size as a whole so that recycled aggregate for concrete of 25 mm or less suitable for KS F 2527 (concrete aggregate) passes through and is selected, and has a vibration function through a normal vibration means. do. Here, since the vibration means may apply a conventional technique, a detailed description thereof will be omitted.

다음으로, 망커버(200)는 선별망체(100)의 입구쪽 상면 일부분을 선택적으로 덮게 설치되고, 10mm 이하의 순환골재가 통과하는 망 구조를 갖게 구성된다. 이러한 망커버(200)는 클립(400)을 통해 선별망체(100)에 고정되는데, 이때 클립(400)은 망커버(200)의 저면에 일체로 돌출 형성되어 선별망체(100)에 끼움 고정되는 구조를 갖도록 하는 것이 바람직하나, 별도의 클립(400)을 이용하여 결속하는 방식으로 고정되게 설치할 수도 있을 것이다.Next, the mesh cover 200 is installed to selectively cover a portion of the upper surface of the inlet side of the screening mesh 100, and is configured to have a mesh structure through which circulating aggregates of 10 mm or less pass. Such a mesh cover 200 is fixed to the screening mesh 100 through a clip 400, in which case the clip 400 is integrally formed protruding from the bottom surface of the mesh cover 200 to be fitted and fixed to the screening mesh 100. It is preferable to have a structure, but it may be fixedly installed in a binding manner using a separate clip 400 .

그리고 망커버(200)는 선별망체(100)의 입구쪽 상면 일부분을 덮도록 올려 놓고 상단 부분만 클립(400)을 통해 선별망체(100)에 고정되도록 구성하는 것이 바람직하다. 그러면 선별망체(100)가 진동할 때 그 진동력에 의해 망커버(200)가 상단의 클립(400)을 기준으로 하단이 들어올려졌다 내려갔다 하면서 투입되는 순환골재를 터는 방식으로 선별력을 증가시켜 10mm 이하의 순환골재를 보다 효과적으로 선별할 수 있게 된다. 물론, 본 실시예에서는 망커버(200)가 상단만 고정되어 있으나 경우에 따라서는 전체적으로 고정되게 설치할 수도 있을 것이다.And it is preferable that the mesh cover 200 is placed so as to cover a portion of the upper surface of the inlet side of the screening mesh 100 and only the upper part is fixed to the screening mesh 100 through the clip 400 . Then, when the sorting mesh 100 vibrates, the mesh cover 200 increases the sorting force in a way that the bottom of the mesh cover 200 is lifted up and down based on the clip 400 at the top by the vibrating force and bursts the recycled aggregate input. It is possible to more effectively select recycled aggregates of 10 mm or less. Of course, in the present embodiment, only the upper end of the mesh cover 200 is fixed, but in some cases, it may be installed to be fixed as a whole.

다음으로, 차단커버(300)는 선별망체(100)의 출구쪽 상면 일부분을 덮도록 설치되고, 오버사이즈의 순환골재, 저품질 순환골재가 선별과정 없이 신속히 통과할 수 있는 밀폐 구조를 갖게 구성된다. 이러한 차단커버(300)는 클립(400)을 통해 선별망체(100)에 고정되는데, 이때 클립(400)은 차단커버(300)의 저면에 일체로 돌출 형성되어 선별망체(100)에 끼움 고정되는 구조를 갖도록 하는 것이 바람직하나, 별도의 클립(400)을 이용하여 결속하는 방식으로 고정되게 설치할 수도 있을 것이다. 그리고 차단커버(300)는 선별망체(100)에 전체적으로 고정되게 설치하는 것이 바람직하다.Next, the blocking cover 300 is installed to cover a portion of the upper surface of the outlet side of the sorting mesh 100, and has a closed structure through which oversized recycled aggregate and low-quality recycled aggregate can pass quickly without a screening process. This blocking cover 300 is fixed to the screening mesh 100 through the clip 400, at this time, the clip 400 is integrally formed protruding from the bottom surface of the blocking cover 300 to be fitted and fixed to the screening mesh 100 It is preferable to have a structure, but it may be fixedly installed in a binding manner using a separate clip 400 . And it is preferable to install the blocking cover 300 to be fixed as a whole to the screening net body 100 .

이러한 구성에 의해 본 발명은 선별망체(100)에 망커버(200)와 차단커버(300)를 설치하였을 때, 선별망체(100)의 입구쪽은 망커버(200)를 통해 10mm 이하의 순환골재가 통과하여 선별되는 초기선별구간(R1)이 형성되고, 선별망체(100)의 중간 부분은 KS F 2527에 적합한 25mm 이하의 콘크리트용 순환골재가 통과하여 선별되는 주선별구간(R2)이 형성되며, 선별망체(100)의 출구쪽은 차단커버(300)를 통해 선별 작업이 이루어지지 않게 하고 오버사이즈, 저품질 순환골재가 통과하지 못하게 하여 신속히 회수해 재파쇄공정으로 이송할 수 있는 리턴구간(R3)이 형성된다.According to this configuration, the present invention provides a circulating aggregate of 10 mm or less through the mesh cover 200 at the entrance of the screening mesh 100 when the mesh cover 200 and the blocking cover 300 are installed in the screening mesh 100 . The initial sorting section (R1) is formed through which is passed, and the middle part of the sorting net (100) is formed by the main sorting section (R2) in which recycled aggregate for concrete of 25 mm or less suitable for KS F 2527 passes through and is sorted. , the exit side of the sorting mesh 100 is a return section (R3) that prevents the sorting operation through the blocking cover 300 and prevents oversized, low-quality recycled aggregate from passing through and can be quickly recovered and transferred to the re-crushing process ) is formed.

즉, 본 발명은 선별망체(100)의 상면에 망커버(200)와 차단커버(300)가 필요한 개수만큼 연속되게 설치되는 것으로, 망커버(200)와 차단커버(300)의 개수에 의해 초기선별구간(R1), 주선별구간(R2), 리턴구간(R3)의 거리를 결정하게 된다.That is, in the present invention, the network cover 200 and the blocking cover 300 are continuously installed as many as necessary on the upper surface of the screening network 100 , and the initial by the number of the mesh cover 200 and the blocking cover 300 . The distance between the selection section R1, the main selection section R2, and the return section R3 is determined.

그리고 망커버(200)와 차단커버(300)는 도 2에 도시된 바와 같이 선별망체(100)의 폭방향에 맞게 길게 제작하여 하나로 설치할 수 있지만, 도 4와 도 5에 도시된 바와 같이 여러 조각으로 구분되게 제작하여 여러 조각을 모듈식으로 설치할 수도 있을 것이다.In addition, the mesh cover 200 and the blocking cover 300 can be manufactured to fit the width direction of the screening mesh 100 and installed as one, as shown in FIG. 2, but as shown in FIGS. 4 and 5, several pieces It may be possible to install several pieces in a modular fashion by making them separately.

즉, 도 5에 도시된 바와 같이 선별망체(100)는 정면에서 보았을 때 순환골재가 퍼질 수 있도록 그 단면이 호 형상으로 라운드지게 형성되는데, 망커버(200)와 차단커버(300)를 선별망체(100)의 호형상에 맞게 제작하는 것 보다 여러 조각으로 구획을 해서 설치하면 제작성이 좋기 때문에 여러 조각으로 구분해서 모듈식으로 설치할 수 있을 것이다.That is, as shown in FIG. 5, the screening mesh 100 is formed to be round in an arc shape so that the recycled aggregate can be spread when viewed from the front, and the mesh cover 200 and the blocking cover 300 are separated by the screening mesh. (100) It is possible to divide into several pieces and install them in a modular way because the manufacturability is better if they are divided into several pieces rather than manufactured according to the arc shape of (100).

참고로, 본 발명의 설명에서 10mm ~ 25mm 사이의 순환골재를 콘크리트용 순환골재라고 칭하고, 10mm 이하 또는 25mm 이상은 일반 순환골재라고 칭한다. For reference, in the description of the present invention, a recycled aggregate between 10mm and 25mm is called a recycled aggregate for concrete, and a recycled aggregate of 10mm or less or 25mm or more is called a general recycled aggregate.

이제, 이와 같이 구성된 본 발명에 따른 콘크리트용 순환골재 선별장치의 작동 관계를 설명한다.Now, the operational relationship of the recycling aggregate sorting device for concrete according to the present invention configured as described above will be described.

본 발명에 따른 선별망체(100)의 입구쪽으로 별도의 컨베이어를 통해 파쇄 과정을 거친 40mm 이하의 순환골재를 투입하면, 선별망체(100)가 진동하면서 순환골재가 출구 쪽으로 이동하게 된다. 이때, 10mm 이하의 순환골재는 초기선별구간(R1)에서 망커버(200)와 선별망체(100)를 통과하면서 선별되고, 10mm 이상 사이즈의 순환골재만 주선별구간(R2)으로 안내된다. 그리고 10mm 이상 사이즈의 순환골재가 주선별구간(R2)을 통과할 때 진동에 의해 상대적으로 사이즈가 작고 비중이 무거운 고품질 콘크리트용 순환골재는 하부(선별망체 표면)에 위치하고, 시멘트모르타르가 부착되어 사이즈가 크고 비중이 가벼운 저품질 순환골재는 상부(선별망체 표면에서 멀어지는)에 위치하여 고품질 콘크리트용 순환골재만 선별망체를 통과하면서 먼저 선별되고 저품질 순환골재는 선별망체를 통과하기 전에 바로 리턴구간(R3)으로 진입하면서 회수된다.When recycled aggregate of 40 mm or less that has undergone a crushing process is put into the inlet of the screening mesh 100 according to the present invention through a separate conveyor, the screening mesh 100 vibrates and the recycled aggregate moves toward the exit. At this time, the recycled aggregate of 10mm or less is selected while passing through the mesh cover 200 and the screening mesh 100 in the initial screening section (R1), and only the recycled aggregate of size 10mm or more is guided to the main screening section (R2). And when recycled aggregate with a size of 10mm or more passes through the main sorting section (R2), the high-quality recycled aggregate for concrete with a relatively small size and heavy specific gravity is located at the lower part (surface of the sorting mesh) due to vibration, and the cement mortar is attached to the size Low-quality recycled aggregate, which is large and light in specific gravity, is located at the upper part (away from the surface of the screening screen), so only high-quality recycled aggregate for concrete is selected first while passing through the screening mesh, and the low-quality recycled aggregate is returned immediately before passing through the screening mesh (R3) It is recovered upon entry into

즉, 진동에 의해 상하로 구분되는 고품질 순환골재와 저품질 순환골재 중 고품질 순환골재는 선별망체(100)를 통과하여 선별되지만 저품질 순환골재는 선별망체(100)를 통과하기 전에 리턴구간(R3)으로 안내되어 재파쇄를 위해 회수되는 것이다. 물론, 선별망체(100)를 통과하는 고품질 순환골재는 25mm 이하 사이즈만 통과하게 되고, 25mm 이상 사이즈의 순환골재는 선별망체(100)를 통과하지 못하고 리턴구간(R3)으로 안내되어 회수된다. 그리고 회수된 25mm 이상의 오버사이즈 순환골재와 저품질 순환골재는 다시 파쇄 작업을 거쳐 파쇄된 후 본 발명에 따른 선별망체(100)를 통해 선별된다.That is, high-quality recycled aggregate among high-quality recycled aggregate and low-quality recycled aggregate divided up and down by vibration passes through the screening mesh 100 and is sorted, but the low-quality recycled aggregate is returned to the return section (R3) before passing through the screening mesh 100. Guided and returned for re-shredding. Of course, the high-quality recycled aggregate passing through the screening mesh 100 passes through only the size of 25 mm or less, and the recycled aggregate of 25 mm or more size does not pass through the screening mesh 100 and is guided to the return section R3 and recovered. And the recovered oversized recycled aggregate of 25 mm or more and low-quality recycled aggregate are again crushed through a crushing operation and then screened through the sorting mesh 100 according to the present invention.

이상에서와같이 본 발명은 특정의 실시 예와 관련하여 도시 및 설명하였지만, 청구범위에 의해 나타난 발명의 사상 및 영역으로부터 벗어나지 않는 한도 내에서 다양한 개조 및 변화 가능하다는 것을 당 업계에서 통상의 지식을 가진 자라면 누구나 쉽게 알 수 있을 것이다.As described above, the present invention has been shown and described in relation to specific embodiments, but it is known in the art that various modifications and changes are possible without departing from the spirit and scope of the invention as defined by the claims. When you grow up, everyone will know easily.
