Description

건조기의 스크루{A screw of dryer}Screw of dryer

본 발명은 건조기 스크루에 관한 것으로, 더욱 상세하게는 건조기의 내부에 투입된 케이크 상태의 폐기물을 드럼 내벽면에 얇게 코팅하는 코팅스크레이퍼들과, 이와 짝으로 코팅된 슬러지표면을 긁어 이송시키는 이송스크레이퍼들을 궤적이 서로 접하도록 다수개 설치하여 슬러지를 연속적으로 코팅하면서 이송시키도록 하여건조 성능을 높인 건조기 스크루에 관한 것이다.The present invention relates to a dryer screw, and more particularly, coating scrapers for thinly coating a cake waste introduced into the dryer on an inner wall of a drum, and transport scrapers for scraping and transporting a sludge surface coated with a pair thereof. The present invention relates to a dryer screw having a plurality of installations to be in contact with each other so that sludge is continuously coated and transported, thereby improving drying performance.

일반적으로 슬러지나 음식물 쓰레기는 각종 오염물질을 함유하고 있고, 음식물 쓰레기에는 많은 염분을 함유하고 있어 이들의 처리에 많은 곤란성이 있었다.In general, sludge and food waste contain various contaminants, and the food waste contains a lot of salts, which causes a lot of difficulties in their treatment.

지금까지는 이러한 폐기물을 매립처리에 의존하였으나, 침출수로 인하여 토양 및 수질오염과 같은 환경오염을 일으키기 때문에 이제는 주로 소각처리에 의존하고 있다.Until now, these wastes have been relied on for landfill treatment, but now they rely mainly on incineration treatments because leachate causes environmental pollution such as soil and water pollution.

물론 음식물 쓰레기와 같은 경우에는 동물의 사료나 퇴비로 재활용하는 방법이 있기는 하지만 상술한 바와 같이 높은 염분을 가지고 있고 또 미생물에 의한 독소로 인하여 부작용이 많아 활성화되지 않고 있다.Of course, in the case of food waste, there is a method of recycling to animal feed or compost, but has a high salinity as described above, and due to the toxins caused by microorganisms, many side effects are not activated.

이러한 슬러지나 음식물 쓰레기와 같은 폐기물을 소각 처리할 때에는 다량의 수분을 함유하고 있는 관계로 소각전 반드시 수분을 제거하는 공정을 거쳐야만 한다.When incineration of waste such as sludge or food waste contains a large amount of water, it must go through a process of removing water before incineration.

하지만 수분을 제거하는 데에는 많은 에너지를 필요로 하기 때문에 소각처리시 많은 시간과 비용이 소요되는 폐단이 있어 경제적이지 못한 단점이 있었다.However, since it requires a lot of energy to remove moisture, there is a disadvantage that it is not economical because there is a waste of time and cost when incineration.

본 출원인은 이러한 단점을 보완하기 위해 폐기물을 건조시켜 소각시키고, 그 소각열을 다시 폐기물의 건조에 재활용하도록 함으로써 에너지를 절감하도록 하는 방법을 특허출원번호 제2001-24713호로 소개한 바있다.Applicant has introduced a patent application No. 2001-24713, a method to save energy by drying the waste to incineration, and the heat of incineration again to dry the waste to compensate for this disadvantage.

선 출원된 폐기물 쓰레기 소각장치는 폐기물을 건조시킬 때 박막건조로를 사용하고 있다.The previously filed waste incinerator uses a thin film drying furnace to dry the waste.

박막건조로는 다단으로 구성되고 소각로의 폐기물 연소열을 받아 가열되는원통형 드럼의 내부에 투입된 케이크 상태의 슬러지 폐기물을 드럼의 내벽면에 코팅하면서 이를 일방향으로 이송하는 건조스크루를 갖는다. 이 건조스크루는 축의 둘레에 축방향과 평행하면서 드럼 벽면에 소정간격 이격된 상태로 회전되는 코팅스크레이퍼와, 스크레이퍼 둘레에 평철형상의 길이부재를 코일형태로 감아 형성된 나선형 이송날개를 갖는 구조를 이룬다.The thin film drying furnace has a drying screw configured to transfer cake in one direction while coating the inner wall of the drum with the cake-like sludge waste, which is composed of multiple stages and is heated by receiving the waste combustion heat of the incinerator. The drying screw forms a structure having a coating scraper which is rotated in a state spaced apart from the drum wall surface in parallel with the axial direction around the shaft, and a spiral feed wing formed by winding a length member of a flat iron shape in the form of a coil around the scraper.

이러한 건조스크루에 의해 유입된 케이크 상태의 폐기물이 코팅스크루에 의해 드럼벽면에 얇게 입히고 이를 나선형 이송날개가 조금씩 일방향으로 이송시켜 드럼의 열과 내부로 공급된 고온건조공기에 의해 건조되도록 한 것이다.The cake-like waste introduced by the drying screw is thinly coated on the drum wall by the coating screw, and the spiral conveying blades are gradually transferred in one direction so as to be dried by the drum's heat and the hot drying air supplied into the drum.

상기의 선 출원 박막건조로는 적은 에너지로 수분이 많은 폐기물을 신속하게 건조시킬 수 있는 효과는 있으나, 스크레이퍼로 케이크 상태의 폐기물을 드럼의 내벽면에 코팅시키고 또 나선형 이송날개로 이송시킬 때 수분이 증발하면서 점성이 증가하여 스크레이퍼와 나선형 이송날개에 폐기물이 눌어붙어 건조기의 성능을 저하시키는 문제점이 있었다.The thin film drying method of the above-mentioned application has the effect of rapidly drying a large amount of waste with little energy, but moisture is evaporated when the scrape-like waste is coated on the inner wall of the drum with a scraper and transferred to the spiral feed vane. While increasing the viscosity, there was a problem that the waste is pressed to the scraper and the spiral feed vanes to reduce the performance of the dryer.

또한 이송스크레이퍼가 회전하면서 폐기물을 내벽면에 얇게 입힐 때 점성을 가진 폐기물이 이송스크레이퍼를 타고 넘어가 드럼의 내벽면에 잘 입혀지지 않게 되는 단점이 있었다.In addition, when the transfer scraper is rotated and the waste is thinly coated on the inner wall surface, the viscous waste material is not easily coated on the inner wall surface of the drum through the transfer scraper.

또한 나선형 이송스크레이퍼가 일정높이를 갖기 때문에 이송스크레이퍼의 나선 간격 사이의 공간에는 열풍이 전달되지 않아 슬러지가 건조되면서 발생된 스팀이 배출되지 않고 나선형 이송스크레이퍼의 사이의 공간에 머무르게 되어 건조효율을 저하시키는 단점이 있었다.In addition, since the spiral feed scraper has a certain height, hot air is not transmitted to the space between the spiral gaps of the feed scraper, so that the steam generated as the sludge is dried is not discharged and stays in the space between the spiral feed scrapers, thereby reducing the drying efficiency. There was a downside.

또한 건조스크루의 구조가 복잡해져 제조가 어렵고 또 무게가 많이나가 장시간 사용시 처짐현상이 발생될 우려가 있었다.In addition, the structure of the dry screw is difficult to manufacture and the weight is too much, there was a fear that the phenomenon of sag when using a long time.

본 발명은 선 출원된 박막건조로의 단점을 해소하기 위해 창안된 것으로,The present invention was devised to solve the shortcomings of the previously filed thin film drying furnace,

건조기의 내부에 오리발과 같은 면적이 넓은 판상체로서 투입된 케이크 상태의 폐기물을 드럼 내벽면에 얇게 코팅하는 코팅스크레이퍼들과, 이와 짝으로 코팅된 슬러지표면을 긁어 이송시키는 이송스크레이퍼들로 다수개 구성하여 폐기물의 점성이 증가하여도 들어붙는 현상을 방지하여 성능을 배가시키고, 또 건조스크루의 구조를 단순화하여 제조가 쉽고 장시간 사용에도 처짐현상과 같은 문제점이 발생되지 않도록 하는데 건조로를 제공하는데 그 목적이 있다.It consists of a plurality of coating scrapers for thinly coating the cake-like waste put into the inside of the dryer as a large plate like flippers on the inner wall of the drum, and a transfer scraper for scraping and transporting the sludge surface coated with this. The purpose is to provide a drying furnace to prevent the sticking phenomenon even if the viscosity of the waste increases, and also to simplify the structure of the drying screw, making it easy to manufacture and preventing problems such as sagging even after long-term use. .

또한 본 발명의 다른 목적은 내부에 스팀이 머무르게 되는 공간을 제거하여 발생된 스팀이 신속하게 외부로 배출되도록 하여 건조 성능을 더욱더 향상시킬 수 있도록 하는 건조로를 제공하는데 있다.In addition, another object of the present invention is to provide a drying furnace to remove the space in which the steam stays therein so that the generated steam is quickly discharged to the outside to further improve the drying performance.

상기 목적을 달성하기 위한 본 발명은,The present invention for achieving the above object,

폐기물 유입구와 유출구를 갖는 원통형 드럼의 내부에 폐기물을 드럼의 내부에 얇게 코팅시키면서 이송시켜 건조시키는 건조로의 건조스크루에 있어서,In the drying screw of the drying furnace for transporting and drying the waste thin coating inside the drum inside the cylindrical drum having a waste inlet and outlet,

폐기물을 상기 드럼의 내벽면에 얇게 입혀 코팅하는 코팅스크레이퍼와, 상기 코팅스크레이퍼와 동일 궤적으로 회전하여 상기 드럼에 코팅된 폐기물을 이송시키는 이송스크레이퍼들을 다수개 구비하여 상기 건조 드럼 중심부에 축설한 회전축 상에 서로의 궤적이 겹쳐지는 간격으로 다수개 설치하여 구성되어 달성된다.A coating scraper which coats waste on the inner wall of the drum and coats the waste, and a plurality of transfer scrapers which rotate in the same trajectory as the coating scraper to transfer the waste coated on the drum, and are arranged on the rotary shaft center. It is achieved by constructing a plurality of tracks at intervals that overlap each other.

이하, 본 발명의 실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 건조기 스크루 구조를 나타낸 사시도이고, 도 2는 본 발명의 건조기 스크루 구조를 나타낸 단면도이며, 도 3은 본 발명의 건조기 스크루 구조를 나타낸 측단면도이다.1 is a perspective view showing a dryer screw structure of the present invention, Figure 2 is a cross-sectional view showing a dryer screw structure of the present invention, Figure 3 is a side cross-sectional view showing a dryer screw structure of the present invention.

도시된 바와 같이 수평한 원통형 드럼(20) 내부에 회전축(21)이 중심부에 회전 가능하게 설치되어 있고, 회전축(21)의 둘레에는 드럼(20)의 지름방향으로 형성된 회동축(24)이 길이방향으로 일정간격 다수개 설치되어 있으며, 각 회전축(21)에는 오리발형상의 스크레이퍼가 설치되어 있다.As shown in the figure, the rotating shaft 21 is rotatably installed in the center of the horizontal cylindrical drum 20, and the rotating shaft 24 formed in the radial direction of the drum 20 has a length around the rotating shaft 21. A plurality of constant intervals are provided in the direction, and each rotation shaft 21 is provided with a flipper scraper.

스크레이퍼는 코팅스크레이퍼(25)와 이송스크레이퍼(26)로 구성되며 드럼(20) 지름방향의 회동축(24) 양측에 각각 설치된다.The scraper is composed of a coating scraper 25 and the conveying scraper 26 and are installed on both sides of the rotating shaft 24 in the radial direction of the drum 20.

이때 코팅스크레이퍼(25)는 회전되는 방향으로 뉘어진 형태로 설치되며, 이송스크레이퍼(26)는 스크루와 같이 배출구 대각 방향 쪽으로 경사진 구조를 갖는다. 또 코팅스크레이퍼(25)와 이송스크레이퍼(26)는 같은 궤적을 가져 회전시 일측은 코팅하고 다른 일측은 이송시키는 기능을 수행하게 된다. 특히 코팅스크레이퍼(25)는 그 단부가 드럼(20)의 내벽면과 소정간격으로 이격되게 설치되는데, 이송스크레이퍼(26)는 코팅스크레이퍼(25)보다 약간더 드럼(20)의 내벽면과 가깝게 이격된 구조를 갖는다.At this time, the coating scraper 25 is installed in a form divided in the rotational direction, the conveying scraper 26 has a structure inclined toward the outlet diagonal direction, such as a screw. In addition, the coating scraper 25 and the conveying scraper 26 has the same trajectory to coat one side and rotate the other side during rotation. In particular, the coating scraper 25 is installed so that its end is spaced apart from the inner wall surface of the drum 20 by a predetermined distance, the conveying scraper 26 is slightly closer to the inner wall surface of the drum 20 than the coating scraper 25. Has a structure.

또한 인접한 회동축(24)에 설치된 코팅스크레이퍼(25)와 이송스크레이퍼(26)는 각각 일측 또는 양측에 인접한 코팅 및 이송스크레이퍼(26)의 궤적과 겹치는 궤적을 갖도록 하여 코팅된 폐기물의 이송이 원활히 이루어지도록 구성된다.In addition, the coating scraper 25 and the conveying scraper 26 installed on the adjacent rotating shaft 24 have a trajectory overlapping with the trajectories of the coating and the conveying scraper 26 adjacent to one side or both sides, so that the coated waste is smoothly transferred. It is configured to lose.

그리고 인접 코팅 및 이송스크레이퍼(26)들과 교호로 작동하도록 회전축(21)상에서 서로 엇갈리게 배열되어 있다.And staggered with each other on the rotating shaft 21 to work alternately with adjacent coating and transfer scrapers 26.

이러한 구조에 의해 투입구(22)를 통해 슬러지 또는 음식물 쓰레기 등과 같은 수분을 포함한 폐기물이 유입되면 회전축(21)의 회동축(24) 일단부에 설치된 코팅스크레이퍼(25)가 드럼(20)의 내벽면에 얇게 입혀 코팅하게 된다. 코팅시 코팅스크레이퍼(25)가 진행방향으로 경사져 있으므로 폐기물은 그 경사면에 안내되어 드럼(20)의 내벽면에 원활하게 부착되며, 또 그 단부가 내벽면과 소정간격으로 이격되어 있기 때문에 폐기물은 드럼(20)의 내벽면에 얇게 입혀지게 된다. 따라서 폐기물은 가열된 드럼(20)의 열을 골고루 전달받게 되어 함유된 습기를 신속하게 증발 배출하게되므로 빠른 건조효과가 일어난다. 이어서 회동축(24) 반대편 단부에 설치된 이송스크레이퍼(26)가 코팅된 폐기물의 표면을 긁으면서 지나가게 되면 폐기물은 경사면에 의해 배출구(23) 방향으로 이송시킨다.When the waste containing water such as sludge or food waste flows through the inlet 22 by this structure, the coating scraper 25 installed at one end of the rotating shaft 24 of the rotating shaft 21 is the inner wall surface of the drum 20. Apply a thin coat to the coat. Since the coating scraper 25 is inclined in the advancing direction at the time of coating, the waste is guided to the inclined surface so as to be smoothly attached to the inner wall surface of the drum 20, and the end of the waste is separated from the inner wall surface by a predetermined interval. The inner wall of the 20 is coated thinly. Therefore, the waste is evenly transferred to the heat of the heated drum 20 to quickly evaporate the moisture contained therein occurs a quick drying effect. Subsequently, when the conveying scraper 26 installed at the opposite end of the rotating shaft 24 passes while scratching the surface of the coated waste, the waste is transferred toward the outlet 23 by the inclined surface.

이때 인접한 회동축(24)단에 설치된 코팅스크레이퍼(25)가 이송되는 폐기물을 이어받아 다시 드럼(20)표면에 얇게 입히고 이어서 이송스크레이퍼(26)가 배출구(23)방향으로 이송시킨다. 이러한 동작을 후속 코팅 및 이동스크레이퍼들이 연속적으로 실시하여 폐기물을 건조시킨다. 건조된 폐기물은 다단의 건조드럼(20)을 통과하면서 동일한 공정을 거처 건조되어 소각로로 이송되어 소각되고 그 열은 다시드럼(20)을 가열시키는데 사용되며, 드럼(20)의 내부로도 공급되어 수분을 증발시키는 기능을 수행하면서 동시에 증발된 수분을 외부로 배출시켜 건조효율을 상승시킨다.At this time, the coating scraper 25 installed at the end of the adjacent rotating shaft 24 takes over the waste to be conveyed, and then thinly coats the surface of the drum 20 again, and then the conveying scraper 26 is transferred in the direction of the outlet 23. This operation is subsequently performed by subsequent coating and transfer scrapers to dry the waste. The dried waste is passed through a multi-stage drying drum 20 to be dried and transported to an incinerator for incineration, and the heat is used to heat the drum 20 again and is supplied to the inside of the drum 20. At the same time to perform the function of evaporating the moisture is discharged to the outside to increase the drying efficiency.

이상에서 살펴본 바와 같이 본 고안은 건조기의 내부에 오리발과 같은 면적이 넓은 코팅 및 이송스크레이퍼가 회전축에 지름방향으로 설치된 회동축에 각각 설치되어 투입된 케이크 상태의 폐기물을 드럼 내벽면에 얇게 코팅한 후 이송시키도록 되어 있으므로 폐기물의 점성이 증가하여도 스크루에 들어붙는 현상이 방지되므로 건조기의 성능을 배가시킬 수 있는 효과가 있다.As described above, the present invention is a coating and conveying scraper having a large area such as flippers inside the dryer are installed on the rotating shaft installed in the radial direction on the rotating shaft, respectively, and coated the waste of the cake state injected thinly on the inner wall of the drum and then transferred Since it is supposed to prevent the phenomenon of sticking to the screw even if the viscosity of the waste is increased, there is an effect that can double the performance of the dryer.

또한 전후 스크레이퍼들의 사이에 스팀이 머무를만한 공간이 존재하지 않기 때문에 내부로 투입된 열풍에 의해 슬러지에서 발생된 스팀은 신속하게 배출되므로 높은 건조효율이 배가 되는 효과가 있다.In addition, since there is no space for steam to stay between the front and rear scrapers, the steam generated in the sludge by the hot air introduced into the inside is quickly discharged, thereby increasing the drying efficiency.

또한 구조가 간단하여 제조가 쉽고 비용이 절감되며 무게가 가볍기 때문에 처짐현상이 방지되어 수명을 연장시킬 수 있는 효과가 있다.In addition, since the structure is simple, manufacturing is easy, cost is reduced, and the weight is light, which prevents sagging and extends the life.
