In the recycling processing apparatus for foamed resin molded article consisting of a cooling step of cooling the molded article and a cutting step of cutting to a predetermined size, foreign substances such as dust, which is received by the conveying means of the lift conveyor, the waste molded article crushed through the grinding step At the same time as the storage process can be achieved by the recycling process of the foamed resin molded article characterized in that it comprises a dust collecting step of supplying the waste molded product by its own weight.

이때 상기 분쇄공정은 투입되는 페성형품을 가압하여 납작하게 함과 동시에 부스러뜨리는 1차분쇄공정과, 1차분쇄공정에 의해 납작해지거나 부서진 폐성형품을 더욱 잘게 분쇄하여 일정한 크기의 덩어리 형태가 되도록 하는 2차분쇄공정으로 이루어짐이 바람직하다.At this time, the crushing process is to press the waste molded article to be flattened and simultaneously to crush the first crushing process, and to crush the flattened or shattered waste molded product by the first crushing process more finely to form a lump of a certain size. It is preferable that the secondary grinding process is performed.

이하, 본 발명에 따른 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 따른 발포수지 성형품 재활용 처리방법을 나타낸 블록도로서, 재활용 처리방법은, 발포수지로 제작된 폐성형품을 분쇄기에 투입시켜 분쇄하는 분쇄공정(10)과 집진싸이크론 장치를 이용하여 분쇄된 폐성형품으로부터 먼지 등의 이물질을 제거하는 집진공정(20)과, 분쇄된 폐성형품을 저장부에 저장하는 저장공정(30)과, 저장부에 저장된 덩어리 형태의 폐성형품을 일정량씩 압출기에 공급하여 재활용성형품으로 제작하는 압출성형공정(40)과, 재활용성형품을 냉각시키는 냉각공정(50)과, 커터기를 이용하여 냉각된 재활용성형품을 일정한 길이로 절단하는 절단공정(60)으로 이루어진다.1 is a block diagram showing a method for recycling a foamed resin molded article according to the present invention. The recycling method includes a pulverizing step 10 and a dust collecting cyclone apparatus for pulverizing a waste molded article made of foamed resin into a grinder. A dust collecting step 20 for removing foreign substances such as dust from the pulverized waste molded product, a storage step 30 for storing the pulverized waste molded product in a storage unit, and a lump-shaped waste molded product stored in the storage unit in a predetermined amount The extrusion molding process 40 is supplied to produce a recycled molded article, a cooling process 50 for cooling the recycled molded article, and a cutting process 60 for cutting the cooled recycled molded article to a predetermined length using a cutter.

분쇄공정(10)은 폐성형품을 1차적으로 분쇄하는 1차분쇄공정(11)과, 1차적으로 분쇄된 폐성형품을 2차적으로 분쇄하는 2차분쇄공정(12)으로 나누어지고, 1차분쇄공정(11)에서는 분쇄로울러를 이용하여 투입되는 폐성형품을 가압하여 납작하게 함과 동시에 부스러뜨려 이후에 2차분쇄공정(12)에서 잘게 분쇄하기 용이하도록 하고, 2차분쇄공정(12)에서는 커터를 이용하여 1차분쇄공정(11)에 의해 납작해지거나 부서진 폐성형품을 더욱 잘게 분쇄하여 일정한 크기의 덩어리 형태가 되도록 한다.The grinding step 10 is divided into a primary grinding step 11 for primarily crushing waste molded products, and a secondary grinding step 12 for crushing primarily a waste product that is primarily crushed. In the step (11), the waste molded product introduced by using the grinding roller is pressurized and flattened, and at the same time, it is crushed, so that it can be easily crushed in the second grinding step (12), and the cutter in the second grinding step (12) By using the primary grinding process (11) to flatten or shatter the waste molded product more finely to form a lump form of a constant size.

집진공정(20)은, 분쇄공정(10)에서 분쇄된 덩어리 형태의 폐성형품으로부터 먼지등의 이물질을 제거하는 공정으로, 분쇄공정에서 일정크기의 형태로된 폐성형품이 스크류컨베이어에 의해 이송되어 집진싸이클론 장치를 통해 하부로 낙하할때 집진싸이클론 장치의 상부에 형성된 집진펌프에 의한 진공흡입방식으로 덩어리 형태의 폐성형품에 섞인 먼지 등의 이물질을 집진통로를 통하여 흡입하여 별도의 집진부에 쌓이도록하여 제거함으로써 후술될 압출성형공정(40)에서 덩어리 형태의 폐성형품간에 융착이 용이해지도록 한다.The dust collecting step 20 is a step of removing foreign matters such as dust from the lumped waste molded product pulverized in the crushing step 10. In the crushing step, the waste molded articles having a certain size are transferred and collected by a screw conveyor. When falling to the bottom through the cyclone system, the vacuum suction method is formed by the dust collection pump formed on the upper part of the cyclone system so that foreign matters such as dust mixed in the lump-shaped waste molded products are collected through the dust collecting passage and accumulated in a separate dust collecting unit. In order to facilitate the fusion between the waste molded articles in the form of agglomerate in the extrusion molding process 40 to be described later.

저장공정(30)은 상기 집진공정(20)에서 이물질이 제거된 덩어리 형태의 폐성형품이 낙하하여 저장부에 저장하는 공정이고, 필요시 저장된 덩어리 형태의 폐성형품을 저장부로부터 압출기로 일정량씩 공급할 수 있도록 한다.The storage process 30 is a process of dropping the waste shaped articles in the form of lumps in which foreign substances have been removed in the dust collecting process 20 and storing them in the storage unit. To be able.

압출성형공정(40)은, 압출기로 공급된 덩어리 형태의 폐성형품에 열을 가하여 덩어리 형태의 폐성형품 표면을 녹여 융착이 가능하게 하며, 그 후 금형에 투입하여 일정한 압력으로 가압함으로써 덩어리 형태의 폐성형품을 가압 융착한 새로운 재활용 성형품을 제작한다.Extrusion molding process 40, by applying heat to the lump-form waste molded product supplied to the extruder to melt the surface of the lump-shaped waste molded article to be fused, and then put into the mold and pressurized at a constant pressure to waste the lump-like waste A new recycled molded article is manufactured by pressing and fusion of the molded article.

이때 덩어리 형태의 폐성형품의 가열은 열풍을 이용하여 약 140℃로 가열하는 것이 바람직하고 덩어리 형태의 폐성형품의 융착시 접착제를 점가시켜 더욱 견고한 융착이 이루어지도록 한다.At this time, the heating of the waste molded product in the form of lumps is preferably heated to about 140 ℃ using hot air, and when the fusion of the waste molded articles in the form of lumps to make a more robust fusion.

냉각공정(50)은, 압출성형공정(40)에 의해 제작된 재활용성형품을 냉각시키는 것으로, 냉각수통에 넣어 냉각시키거나, 노즐을 이용하여 냉각수를 직접 재활용성형품에 분사시키거나, 또는 상온에서 공냉시킬 수도 있다.The cooling step 50 cools the recycled molded product produced by the extrusion molding step 40 and cools it by putting it in a cooling water container, spraying the cooling water directly onto the recycled molded product by using a nozzle, or air cooling at room temperature. You can also

절단공정(60)은, 냉각공정(50)에서 냉각되어진 재활용성형품을 일정한 길이로 절단함으로써 재활용성형품을 이용하여 나무 대용, 합판 대용, 충격흡수재, 방수자재, 방진재 등 다른 용도로 재활용할 수 있도록 한다.The cutting process 60 cuts the recycled molded product cooled in the cooling process 50 to a predetermined length so that the recycled molded product can be recycled to other uses such as wood substitutes, plywood substitutes, shock absorbers, waterproof materials, and dustproof materials. .

이상에서와 같이 본 발명에 따른 발포수지 성형품의 재활용 처리방법에 의하면, 열가소성 발포수지 또는 열경화성 발포수지를 재활용하여 다른 용도의 재료로 사용할수 있게 됨으로써 종전의 소각 및 매립으로 인한 대기 및 토양등의 환경오염이 방지되고, 재활용품을 이용하여 보다 저렴한 가격으로 자재를 제공할 수 있는 효과가 있다.As described above, according to the recycling treatment method of the foamed resin molded article according to the present invention, the thermoplastic foamed resin or thermosetting foamed resin can be recycled to be used as a material for other uses, so that the environment such as the atmosphere and soil due to the previous incineration and landfill Pollution is prevented, and it is possible to provide materials at a lower price by using recycled materials.
