Abstract

PURPOSE: A wasted synthetic resin melt extruder capable of impurity removal and water removal is provided to solve the incompleteness of water removal which is indicated in a reproducer using wet cleaning mode and improve the quality of the recycled synthetic resin by removing foreign metal substances. CONSTITUTION: A wasted synthetic resin melt extruder capable of impurity removal and water removal melts and extrudes recycling synthetic resin which is washed after being pelletized. The melt extruder comprises: an electromagnet cask (20); a magnet cylinder (30); a compression object (40); a transfer screw (50); and heating means (60). The electromagnet cask is rotatably arranged inside an inlet part of a housing (11) of the melt extruder by a drive motor (25). The magnet cylinder in which electromagnet is installed in a cylinder head, and foreign metal substances of the inside are adhered to the electromagnet is operated with fluid pressure. The compression consists of a hollow cylindrical shape body (41), and an inner diameter is successively decreased. In the transfer screw, a helical blade (52) is formed around a screw bar (51). The compression object is heated with the heating means by supplying electricity to a coil which is laid inside the compression object (40). In the heated compression object, moisture is evaporated and spurts while the temperature of pellet rises.

이물질 제거와 수분 제거가 가능한 폐합성수지 용융 압출 장치 { A melting and pressing out machine of recycling synthetic resins } Waste synthetic resin extrusion equipment that can remove foreign substances and remove water {A melting and pressing out machine of recycling synthetic resins}

본 발명은 이물질 제거와 수분 제거가 가능한 폐합성수지 용융 압출 장치에 관한 것으로서, 더욱 상세하게는 농업, 가정, 산업용 등으로 사용된 폐합성수지를 용융 배출하는 압출장치를 개선한 것으로 수세식으로 세척된 폐합성수지를 탈수가 가능할 뿐만 아니라 금속 이물질을 제거할 수 있도록 구성한 이물질 제거와 수분 제거가 가능한 폐합성수지 용융 압출 장치에 관한 것이다.
The present invention relates to a waste synthetic resin melt extrusion apparatus capable of removing foreign substances and water, and more particularly, to improve an extrusion apparatus for melting and discharging waste synthetic resins used in agriculture, home, and industry. The present invention relates to a waste synthetic resin melt extrusion apparatus capable of removing debris and removing moisture, as well as dehydration.

폐합성수지, 보다 상세하게는 열가소성 수지, 특히 농촌에서 작물재배용으로 많이 사용되는 PE 등의 소재로 이루어진 폐 필름을 재생하기 위한 기술로는 수집된 폐수지를 분쇄하고 성형하는 것과 관련된 공개특허 제1993-0000226호(1993.01.15) '폐수지를 이용하는 합성수지 성형장치'가 있고, 공개특허 제2001-0046817호(2001.06.15) '폐수지의 대형용융장치', 등록특허 제0365953호(2002.12.11) '폐비닐의 재생방법 및 폐비닐 펠렛 성형장치', 실용신안등록 제0340378호(2004.01.20) '폐비닐을 이용한 재생칩 제조장치'가 개시되어 있다.Techniques for recycling waste films made of waste synthetic resins, more particularly thermoplastics, especially PE, which are widely used for crop cultivation in rural areas, include techniques related to grinding and molding the collected waste resins. (1993.01.15) 'Synthetic resin molding apparatus using waste resin', Patent Publication No. 2001-0046817 (2001.06.15) 'Large melt apparatus of waste resin', Patent No. 0365953 (2002.12.11) The recycling method and waste vinyl pellet forming device ', Utility Model Registration No. 0340378 (2004.01.20)' Recycling chip manufacturing apparatus using waste vinyl 'is disclosed.

페합성수지는 수거된 폐합성수지가 펠렛화시스템에서 최초 파쇄기를 거친 후 압출장치를 거쳐, 다시 절단기를 통과하면서 펠렛화된다. 폐합성수지 펠렛화 시스템을 구성하는 2차 탈수기를 거쳐 분쇄-세척-탈수된 폐합성수지를 공급받으면서 용융압출장치로 안정된 투입이 가능하도록 구성된다.The waste synthetic resin is pelletized while the collected waste synthetic resin passes through the first crusher in the pelletizing system, then through an extrusion apparatus, and then passes through a cutter. It is configured to enable stable feeding into the melt extrusion apparatus while receiving the crushed-washed-dehydrated waste synthetic resin through a secondary dehydrator constituting the waste synthetic resin pelletizing system.

용융된 폐합성수지가 방출되는 후단에는 배출구가 구비되어 있으며, 국수와 같은 일정 형상과 단면적의 가닥으로 연속 배출하는 압출기 상기 배출구에 배열되어 있으며, 또 이러한 하우징에는 용융열에 의하여 폐합성수지에 포함된 습기가 증발될 경우 이의 배출을 위하여 증기배출구가 형성되어 있다.A discharge port is provided at the rear end of the molten waste synthetic resin, and is arranged at the outlet of the extruder continuously discharging the strands of a predetermined shape and cross-sectional area such as noodles, and the housing contains moisture contained in the waste synthetic resin by the heat of melting. When evaporated, a steam outlet is formed for its discharge.

이러한 하우징에 내장된 이송스크류와 탈수스크류는 각각 봉상체(棒狀體)와, 봉상체의 회전방향과 일치하는 방향으로 상기 봉상체의 외주면에 일정 피치(pitch)를 형성하며 연속되게 형성되어 있는 나선의 날개부로 이루어진다.The conveying screw and the dewatering screw embedded in the housing are formed continuously, forming a pitch on the outer circumferential surface of the rod in a direction consistent with the direction of rotation of the rod and the rod. It consists of spiral wings.

이러한 종래 폐합성수지 재생장치와 관련된 기술들은 현실화되지 못하거나 설치되더라도 잦은 고장과 높은 운전비용, 그리고 저품질의 재생합성수지 생산 등으로 결국은 지속적으로 사용되지 못하고 있는데, 이러한 공지된 폐합성수지 세척-용융-성형 재생장치가 낮은 현실성의 이유는 폐합성수지의 완벽한 세척이 가능하여야 고품질의 재생수지 생산이 가능한데 꼬이고 무수히 겹쳐진 합성수지 필름에 고착된 흙 등의 오물 제거가 쉽지 않기 때문이다.Even though the technologies related to the conventional waste synthetic resin recycling apparatus are not realized or installed, they are not continuously used due to frequent failures, high operating costs, and production of low quality recycled synthetic resins. The reason for the low practicality of the regeneration device is that the complete cleaning of the waste synthetic resin is possible to produce high quality recycled resin because it is not easy to remove the dirt and the like stuck on the overlapped and overlapping synthetic resin film.

또 특히 물을 이용한 습식 세척방식을 활용하여 비교적 완벽하게 폐합성수지의 오물을 제거하더라도 단순히 탈수과정만으로는 수분을 완벽하게 제거할 수 없어 성형된 재생수지에 수분이 포함되어 이후 활용시 생산된 제품의 품질을 저하시키며, 세척시 사용된 수분의 완벽한 제거를 위하여 탈수과정에 이어 별도로 열풍 등을 이용한 건조를 행할 경우 재생이 소요되는 비용이 높아지므로 단가경쟁력이 떨어지는 문제가 있다.
In addition, even if the soil of the waste synthetic resin is completely removed by using the wet washing method using water, it is impossible to completely remove the moisture by simply dehydration. In order to completely reduce the water used during the washing, when the drying is performed separately using a hot air following the dehydration process, the cost of regeneration increases, and thus there is a problem that the cost competitiveness falls.

본 발명은 전술한 바와 같은 문제를 해결하기 위해 이루어진 것으로서, 공지된 폐합성수지 세척-용융-성형 재생장치, 특히 습식 세척 방식을 사용하는 재생장치에서 지적된 수분 제거의 불완전성을 해결하기 위하여 제안된 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve the problems described above, and has been proposed to solve the imperfections of water removal pointed out in known waste synthetic resin wash-melt-molding regenerators, in particular regenerators using a wet cleaning method. will be.

그리고 포함된 금속 이물질을 세척된 상태에서 제거하여 제품의 품질이 향상되도록 구성하고자 한다.And to remove the included metal foreign matter in a washed state to configure the product quality is improved.

본 발명은 펠릿화되어 세척된 재활용 합성수지를 용융압출하되 이물질 제거와 수분 제거가 가능한 폐합성수지 용융 압출 장치를 개선한 것으로서, 용융압출장치(10)의 원형관 형태의 하우징(11)의 입구에 전자석통(20)을 회전가능하게 고정하고, 전자석통(20) 다음에 바로 압축체(40)가 하우징(11) 내부에 설치되며, 압축체(40) 다음에 이송스크류(50)가 설치된다.The present invention improves the waste synthetic resin melt extrusion apparatus that melt-extruded recycled synthetic resin that is pelletized and washed, and is capable of removing foreign substances and water. The cylinder 20 is rotatably fixed, and immediately after the electromagnet 20, the compression body 40 is installed inside the housing 11, and the transfer screw 50 is installed after the compression body 40.

전자석통(20)은 용융압출장치의 하우징(11)의 입구부 내부에 구동모터(25)에 의해 회전 가능하게 설치되는데, 중공의 원통형 통체(21)의 내경에 다수개의 홈부(22)가 형성되고, 이 홈부(22)에 금속이물질이나, 금속이물질이 포함된 펠릿이 들어가 있다가, 후술할 개폐도어(28)가 열리면 외부로 빠져나오게 된다.The electromagnet 20 is rotatably installed by the drive motor 25 inside the inlet of the housing 11 of the melt extrusion apparatus, and a plurality of grooves 22 are formed in the inner diameter of the hollow cylindrical cylinder 21. Then, a metal foreign matter or pellets containing the metal foreign matter enter the groove portion 22, and then the opening / closing door 28 to be described later opens to the outside.
