본 발명은 스크류가 내장되고 외주면에 다수의 탈수공이 형성된 실린더를 통하여 수세(水洗)된 폐합성수지에서 수분을 제거하는 폐합성수지 탈수장치에 관한 것으로, 스크류를 종방향으로 관통하는 흡입공을 형성하고 이를 흡입펌프와 연결하여, 실린더를 통과하며 탈수된 배출 직전의 폐합성수지에서 잔여 수분을 흡입·배출함으로써 탈수효과를 극대화한 것이다.The present invention relates to a waste synthetic resin dehydration apparatus for removing moisture from waste synthetic resins washed through a cylinder in which a screw is embedded and a plurality of dehydration holes are formed on an outer circumferential surface thereof, and forms a suction hole penetrating the screw in a longitudinal direction. In connection with the suction pump, the dehydration effect is maximized by inhaling and discharging the residual water from the waste synthetic resin just before the discharged through the cylinder.

합성수지는 강도와 물리·화학적 특성이 우수할 뿐 아니라, 성형성이 뛰어나 각종 산업용소재 또는 생활용품의 소재로 널리 사용되고 있으나, 폐기된 후 자연상태에서의 분해가 매우 어려워 환경오염의 요인이 되고 있다.Synthetic resins are not only excellent in strength, physical and chemical properties, but also excellent in formability, and are widely used as materials for various industrial materials or household goods.

이러한 폐합성수지로인한 환경오염 방지와 자원의 재활용을 위하여, 폐기되는 각종 합성수지제품을 수거한 후 새로운 합성수지제품 또는 제품원료로 가공하는 다양한 재활용기법 및 관련 장치가 개발되어, 상당수의 폐합성수지가 재활용되고 있으며, 그 대표적인 예로서 비닐하우스 등에 사용되는 농업용 비닐(vinyl)필름 또는 비닐시트의 재활용을 들 수 있다.In order to prevent environmental pollution and recycle resources due to such waste synthetic resins, various recycling techniques and related apparatuses have been developed for collecting various synthetic resin products that are discarded and then processed into new synthetic resin products or product raw materials, and a large number of waste synthetic resins are recycled. Representative examples thereof include recycling of agricultural vinyl films or vinyl sheets used in vinyl houses.

폐합성수지의 재활용은 폐합성수지를 수집 및 선별하고, 불순물이나 오염을 제거하는 전처리과정을 거친 후, 용융 및 기타 성형과정을 거쳐 이루어지게 되는데, 용융을 비롯한 성형과정에 있어서 폐합성수지의 수분 함량이 높을 경우 완제품의 불량이나 기계고장을 유발하므로, 전처리과정에서 수분을 제거하는 것이 매우 중요하다.Recycling of the waste synthetic resin is carried out through the pretreatment process of collecting and sorting the waste synthetic resin, removing impurities and contamination, and then melting and other molding processes. The water content of the waste synthetic resin in the molding process including melting is high. In this case, it is very important to remove water during the pretreatment process because it may cause the failure of the finished product or mechanical failure.

특히, 폐합성수지에 포함된 불순물이나 오염을 제거하기 위하여, 선별된 폐합성수지를 수세(水洗)하는 과정을 거치게 되는데, 이 과정에서 다량의 수분이 포함되게 되므로, 탈수장치를 통하여 폐합성수지에 포함된 수분을 인위적으로 제거하게 된다.In particular, in order to remove impurities or contamination contained in the waste synthetic resin, the selected waste synthetic resin is washed with water. In this process, a large amount of water is contained, so that the waste resin is contained in the waste synthetic resin through a dehydration device. It will artificially remove moisture.

이러한 폐합성수지 탈수장치의 예로는 본 발명의 출원인이 출원한 바 있는 실용신안등록 제176862호 "폐비닐 착수장치"를 들 수 있으며, 그 기본적인 구성이 도 1에 도시되어 있다.An example of such a waste synthetic resin dehydration device is Utility Model Registration No. 176862, "Waste vinyl impingement device" filed by the applicant of the present invention, the basic configuration is shown in FIG.

도 1에서와 같은 종래의 폐합성수지 탈수장치는 스크류(10)가 내장되고 외주 면에 다수의 탈수공(33)이 천공된 실린더(30)를 주요 구성요소로 하며, 실린더(30) 내부로 투입된 함수(含水)상태의 폐합성수지(91)가 스크류(10)가 회전함에 따라 이송되면서 압착(壓搾)되어, 폐합성수지(91) 내에 포함된 수분이 탈수공(33)을 통하여 배출되고, 배출된 폐수(92)는 집수부(34)를 통하여 외부로 배출되게 된다.In the conventional waste synthetic resin dehydration apparatus as shown in FIG. 1, the main component is a cylinder 30 having a screw 10 embedded therein and a plurality of dehydration holes 33 perforated on an outer circumferential surface thereof, and introduced into the cylinder 30. The waste synthetic resin 91 in a hydrous state is compressed while being conveyed as the screw 10 rotates, and the water contained in the waste synthetic resin 91 is discharged through the dehydration hole 33 and discharged. Waste water 92 is discharged to the outside through the collecting portion (34).

이러한 스크류식 폐합성수지 탈수장치를 통해 자연상태에서의 건조나 원심탈수기에 비하여, 탈수에 소요되는 시간은 물론 탈수효과에 있어서 획기적인 개선이 이루어졌다고 할 수 있으나, 도 2에서와 같이, 탈수된 후 실린더(30) 선단의 노즐(31)을 통하여 배출되는 폐합성수지(91) 중심부에 미처 탈수되지 않는 폐수(92)가 잔류되는 경우가 있었다.Compared to the drying or centrifugal dehydrator in the natural state through the screw waste synthetic resin dehydration device, it can be said that the time required for dehydration, as well as a significant improvement in the dehydration effect, as shown in Figure 2, after dehydration cylinder (30) In some cases, wastewater 92, which cannot be dehydrated, remains in the center of the waste synthetic resin 91 discharged through the nozzle 31 at the tip.

이러한 폐수(92)의 잔류현상은 노즐(31)에 인접한 스크류(10) 선단부의 압력이 낮아지면서 스크류(10) 선단과 노즐(31) 사이에 폐수(92)가 모이면서 발생하게 되는데, 스크류식 폐합성수지 탈수장치의 탈수효율을 저하하는 주된 요인이 되고 있다.The residual phenomenon of the wastewater 92 is generated when the wastewater 92 is collected between the tip of the screw 10 and the nozzle 31 while the pressure of the tip of the screw 10 adjacent to the nozzle 31 is lowered. It has become a major factor in lowering the dewatering efficiency of waste synthetic resin dehydrator.

본 발명은 전술한 문제점을 감안하여 창안한 것으로, 폐합성수지 탈수장치의 스크류를 종방향으로 흡입공이 관통된 중공(中空)스크류로 구성하고, 스크류의 선단에는 흡입공과 연결된 흡입구를 형성하며, 스크류의 말단부는 흡입관을 통하여 흡입펌프와 연결하여, 배출 직전의 폐합성수지에 포함된 폐수를 흡입구, 흡입공 및 흡입관을 통하여 흡입하여 외부로 배출할 수 있도록 한 것이다.
The present invention has been made in view of the above-described problems, and consists of a hollow screw through which suction holes penetrate in the longitudinal direction of the screw of the waste resin dewatering device, and a suction port connected to the suction hole is formed at the tip of the screw, The distal end is connected to the suction pump through the suction pipe, so that the wastewater contained in the waste synthetic resin immediately before discharge can be sucked through the suction port, the suction hole and the suction pipe to be discharged to the outside.

본 발명의 상세한 구성과 작동원리를 첨부된 도면을 통하여 설명하면 다음과 같다.The detailed configuration and operation principle of the present invention will be described with reference to the accompanying drawings.

우선 본 발명은 도 3에서와 같이, 외주면에 다수의 탈수공(33)이 형성된 실린더(30)와, 실린더(30)에 내장된 스크류(10)와 실린더(30) 전면에 결합되는 노즐(31)과 스크류(10)의 말단부와 흡입관(21)을 통하여 연결되는 흡입펌프(20) 등으로 구성되며, 이 밖에도 탈수공(33)을 통하여 유출된 폐수(92)를 집수하기 위한 집수부(34)와 스크류(10)를 구동하기 위한 모터(40) 및 기어(41) 등이 구성되어 있다.First, as shown in FIG. 3, the present invention includes a cylinder 30 having a plurality of dehydration holes 33 formed on an outer circumferential surface thereof, a screw 10 embedded in the cylinder 30, and a nozzle 31 coupled to the front surface of the cylinder 30. ) And the suction pump 20 connected through the distal end of the screw 10 and the suction pipe 21, etc., and the water collecting part 34 for collecting the wastewater 92 discharged through the dehydration hole 33. ), A motor 40 and a gear 41 for driving the screw 10 are configured.

본 발명의 스크류(10)에는 도 4 및 도 5에서와 같이, 스크류(10)의 중심축을 따라 종방향으로 형성된 흡입공(11)이 형성되고, 스크류(10)의 선단에는 흡입공(11)과 연결된 다수의 흡입구(12)가 형성되며, 이 흡입공(11)은 스크류(10)의 말단부에 체결된 흡입관(21)을 통하여 흡입펌프(20)에 연결되게 된다.4 and 5, the suction hole 11 is formed in the longitudinal direction along the central axis of the screw 10, and the suction hole 11 is formed at the tip of the screw 10. A plurality of suction ports 12 are connected to each other, and the suction holes 11 are connected to the suction pump 20 through the suction pipe 21 fastened to the distal end of the screw 10.

회전체인 스크류(10)와 고정체인 흡입관(21)과의 연결은 로터리조인트(Rotary joint)(22)를 통하여 이루어지게 되며, 스크류(10)는 다수의 기어(41)를 통하여 모터(40)와 연결되어 구동되게 되는데, 이러한 연결수단 및 동력전달수단은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 당업자가 선택 적용할 수 있는 사항이므로 이에 대한 청구범위의 구체적인 한정은 하지 않는다.The connection between the rotating chain screw 10 and the fixed suction pipe 21 is made through a rotary joint 22, and the screw 10 is connected to the motor 40 through a plurality of gears 41. The connection means and the power transmission means are selected by those skilled in the art having ordinary skill in the art to which the present invention pertains and are not specifically limited in the claims.

호퍼(32)를 통하여 실린더(30) 내부로 함수(含水)상태의 폐합성수지(91)를 투입하면, 회전하는 스크류(10)에 의하여 이송되게 되는데, 도 3을 통하여 알 수 있는 바와 같이, 스크류(10)의 직경이 선단측으로 점차 확대되도록 형성되어, 이송과정에서 폐합성수지(91)의 압착이 이루어지게 되고, 압착되어 유출된 폐수(92)는 실린더(30)에 형성된 탈수공(33)을 통하여 배출되게 되며, 탈수된 폐합성수지(91)는 실린더(30) 전방에 결합된 노즐(31)을 통하여 배출되게 된다.When the waste synthetic resin 91 in a hydrous state is introduced into the cylinder 30 through the hopper 32, it is transferred by the rotating screw 10, as can be seen from FIG. 3. The diameter of the 10 is formed to gradually expand to the tip side, the compression of the waste synthetic resin 91 is made in the transfer process, the waste water 92 is compressed and discharged to the dewatering hole 33 formed in the cylinder (30) The waste synthetic resin 91 is discharged through the nozzle 31 coupled to the front of the cylinder 30.

실린더(30)의 전면은 노즐(31)을 통하여 개방된 구조이므로, 스크류(10)의 선단과 노즐(31) 사이의 공간은 실린더(30) 내부의 다른 부분에 비하여 압력이 낮아지게 되며, 이로 인하여 스크류(10)의 선단에는 미처 탈수되지 않은 잔류 폐수(92)가 모이게 되는데, 이러한 잔류 폐수(92)는 스크류(10)에 형성된 흡입구(12), 흡입공(11) 및 스크류(10)와 흡입관(21)으로 연결된 흡입펌프(20)를 통하여 외부로 배출되게 되어, 도 6에서와 같이, 잔류 폐수(92)가 배제된 완전 탈수상태의 폐합성수지(91)만이 노즐(31)을 통하여 배출되게 된다.Since the front surface of the cylinder 30 is opened through the nozzle 31, the space between the tip of the screw 10 and the nozzle 31 has a lower pressure than other parts of the cylinder 30. Due to the end of the screw (10) collects the residual wastewater 92, which is not dehydrated, and the residual wastewater (92) is formed with the suction port (12), the suction hole (11) and the screw (10) formed in the screw (10). It is discharged to the outside through the suction pump 20 connected to the suction pipe 21, as shown in Figure 6, only the waste synthetic resin 91 in the completely dehydrated state from which the residual waste water 92 is removed, through the nozzle 31 Will be.

도 7은 스크류(10)에 흡입구(12)를 구성함에 있어서, 스크류(10)의 선단부에 경사방향의 흡입구(12)를 추가로 구성함으로써 보다 원활한 폐수(92)의 흡입이 가능하도록 한 것이다.In FIG. 7, when the inlet 12 is formed in the screw 10, the inlet 12 in the inclined direction is further configured at the distal end of the screw 10 to allow a smoother suction of the wastewater 92.

결국 본 발명의 기술요지는 스크류(10)가 내장되고 외주면에 다수의 탈수공(33)이 형성된 실린더(30)가 설치되어, 실린더(30) 내부로 투입된 함수(含水)상태의 폐합성수지(91)가 실린더(30)에 내장된 스크류(10)가 회전함에 따라 이송되면서, 탈수공(33)을 통하여 폐수(92)가 탈수되는 폐합성수지 탈수장치에 있어서, 스크류(10)를 종방향으로 관통하는 흡입공(11)이 형성되고, 스크류(10)의 선단 에는 흡입공(11)과 연결된 흡입구(12)가 형성되며, 스크류(10)의 말단부는 흡입관(21)을 통하여 흡입펌프(20)와 연결되어, 스크류(10) 전방에 위치한 배출 직전의 폐합성수지(91)에 포함된 폐수(92)를 흡입구(12), 흡입공(11) 및 흡입관(21)을 통하여 흡입하여 외부로 배출함을 특징으로 하는 중공스크류를 이용한 폐합성수지 탈수장치이다.As a result, the technical gist of the present invention includes a cylinder 30 having a screw 10 embedded therein and having a plurality of dehydration holes 33 formed on an outer circumferential surface thereof, so that the waste synthetic resin 91 in a hydrous state injected into the cylinder 30 is formed. In the waste synthetic resin dehydration apparatus in which the wastewater 92 is dewatered through the dehydration hole 33 while the screw 10 embedded in the cylinder 30 is rotated, the screw 10 penetrates in the longitudinal direction. A suction hole 11 is formed, and a suction port 12 connected to the suction hole 11 is formed at the tip of the screw 10, and the distal end of the screw 10 is connected to the suction pump 20 through the suction pipe 21. It is connected to the suction and discharge the waste water 92 contained in the waste synthetic resin 91 immediately before the discharge inlet 12, the suction hole 11 and the suction pipe 21 located in front of the screw 10 to discharge to the outside Waste synthetic resin dehydration apparatus using a hollow screw characterized in that.
