본 고안은 폐슬러지 건조기용 슬러지 이송장치에 관한 것으로, 특히 슬러지 이송을 스피링상의 이송수단으로 슬러지를 이송시키고, 이송수단은 회전축 양단에 설치한 단위판상스크류에 고정 되도록 한 것이다.The present invention relates to a sludge conveying apparatus for a waste sludge dryer, and in particular, conveys sludge to the conveying means on the spring, and the conveying means is fixed to the unit plate screw installed on both ends of the rotating shaft.

일반적으로 폐슬러지는 산업페기물로써 환경오염의 주된요인이다. 이러한 폐슬러지는 염색가공, 폐지재생장치등에서 찌꺼기 상태로 배출 되고, 찌꺼기 상태의 폐슬러지는 산업화가 가속화됨에 따라 배출량도 늘고 있다. 때문에 폐슬러지를 고체화시켜 배출량을 극소화 시키는 시설을 설치사용하는 바, 폐슬러지를 고체화시키는 장치로는 큰 드럼형의 내부에서 가열수단(전기 또는 버너)으로 가열시키고, 드럼외주면에 묻어 건조된 케이크상의 슬러지를 벗겨내는 과정을 반복하는 수단이 있으나, 이는 일회전에 의해 건조 및 분리를 수행하여야 하므로 처리속도가 느린 단점이 있다. 또한 받침판에 슬러지를 공급하고 슬러지위에서 버너불을 공급하여 직접 건조시킨 후 칼날로 긁어내는 방식도 이용되나, 이 경우는 슬러지가 고체화되면서 증발되는 증기에 의해 버너 불이 불완전연소되어 매연을 내뿜게 되므로 2차 오염원인을 제공하고, 불완전 연소되므로 건조 효율이 저하되는 단점이 있다. 또한 연소통 위에 폐슬러지를 공급하여 복사열로써 건조시키는 방식이 제안되었는바, 이때는 회전날개로 복사건조판의 슬러지를 긁어 이송시키는 구조이다 .In general, waste sludge is an industrial waste and is a major factor of environmental pollution. Such waste sludge is discharged in the form of waste from dyeing processing and waste paper recycling equipment, and the amount of waste sludge in the waste state is increasing as industrialization accelerates. For this reason, a facility is used to solidify the waste sludge to minimize the discharge. As a device for solidifying the waste sludge, it is heated in a large drum type by a heating means (electric or burner), and dried on a drum. There is a means for repeating the process of stripping the sludge, but this has a disadvantage in that the processing speed is slow because it has to be dried and separated by one rotation. In addition, the sludge is supplied to the backing plate, and burner is directly dried by supplying burner fire from the sludge, and then scraped with a blade.In this case, the burner fire is incompletely burned by the vapor evaporated as the sludge solidifies, and the smoke is emitted. It provides a secondary pollution cause, and there is a disadvantage that the drying efficiency is lowered because of incomplete combustion. In addition, a method of supplying waste sludge to a combustion cylinder and drying it by radiant heat has been proposed. In this case, the sludge of the radiation drying plate is scraped and transferred by a rotary blade.

이는 제 1도와 같이 예시할 수 있는바, 복사열을 제공하는 연소실(210)위에 호형의 단위 건조판(221)이 연결되어 이루어진 복사건조판(220)에 회전날개수단(230)을 가지는 교반건조유니트(200)가 위치되고, 회전날개수단(230)은 회전축(232)에 십자형고정리브(233)가 있고, 고정리브(233) 단부에는 일정각도의 회전날개(234)가 길이방향으로 설치된다.This can be illustrated as shown in FIG. 1, a stirring drying unit having a rotary blade means 230 on the radiation drying plate 220 is formed by connecting the arc-shaped unit drying plate 221 on the combustion chamber 210 to provide radiant heat 200 is located, the rotary blade means 230 has a cross-shaped fixed rib 233 on the rotating shaft 232, the rotary blade 234 of a predetermined angle is installed in the longitudinal direction at the end of the fixed rib 233.

이는 단위건조판(221)위에서 복사열에 의해 건조되는 슬러지(240)를 회전날개(234)로 긁어내는 형식으로 슬러지(240)를 이송시키므로 슬러지(240)가 완전히 이송되지 않고 잔류하여 복사열을 차단시키는 문제점이 있다. 또한 회전축(232)에 90도간격으로 회전날개(234)를 고정리브(233)를 사용하여 길이 방향으로 길게 설치하므로 슬러지(240)에 부하가 걸리고 이에 따라 작업 효율이 저하되는 단점이 있다.This transports the sludge 240 in the form of scraping the sludge 240 dried by the radiant heat on the unit drying plate 221 with the rotary blade 234, so that the sludge 240 is not completely transferred to block radiant heat. There is a problem. In addition, since the rotary blade 234 is installed in the longitudinal direction using the fixed rib 233 at a 90-degree interval on the rotating shaft 232, the sludge 240 takes a load, thereby reducing the work efficiency.

또한 제1도를 하우징에 장착한 종단면 상태로 도시하면 제 2도와 같이 예시할 수 있는 바, 밀폐형 연소실(210)위에 복사건조판(230)이 있고 복사건조판(230) 및 밀폐형연소실(210)은 하우징(300) 에 고정되고, 하우징(300)의 회전축끼움공(310)에 교반건조유니트(200)의 회전축(232)이 안착된다. 이경우 하우징(300)의 회전축끼움공(310)은 열팽창을 감안하여 회전축(232)보다 상대적으로 직경을 크게한다. 따라서 교반건조유니트(200)를 회전시켜 졸상의 슬러지를 다음단의 반사건조판(220)으로 이송시킬 때 졸상의 슬러지가 회전날개(234)에 묻어 회전축끼움공(310)을 통해 외부로 배출되어 위생상의 문제점이 있다. 혹자는 회전축끼움공(310)내경을 회전축(232) 직경과 같게하면 되지 않겠냐고 하겠지만 열팽창율이 상이하여 건조기의 내구성에 문제가 발생하고, 이를 예방키위해 회전축끼움공(310)의 직경을 상대적으로 크게 할 수 밖에 없고, 그에 따른 외관상의 문제를 감내할 수 밖에 없는 실정이다.In addition, FIG. 1 shows a longitudinal cross-sectional view of the housing in which the radiation drying plate 230 is located on the sealed combustion chamber 210 and the radiation drying plate 230 and the sealed combustion chamber 210 are shown in FIG. Is fixed to the housing 300, the rotary shaft 232 of the stirring drying unit 200 is seated in the rotary shaft fitting hole 310 of the housing 300. In this case, the rotation shaft fitting hole 310 of the housing 300 has a relatively larger diameter than the rotation shaft 232 in consideration of thermal expansion. Therefore, when rotating the stirring drying unit 200 to transfer the sol-like sludge to the reflective drying plate 220 of the next stage, the sol-like sludge is buried in the rotary blade 234 is discharged to the outside through the rotary shaft fitting hole 310 There is a hygiene problem. Some people say that the inner diameter of the rotary shaft fitting hole 310 should be the same as the diameter of the rotary shaft 232, but the thermal expansion rate is different, causing problems in the durability of the dryer, and to prevent this, the diameter of the rotary shaft fitting hole 310 is relatively As a result, it is necessary to increase the size and to deal with the appearance problems.

본 고안은 이를 해결코자 하는 것으로, 교반건조유니트의 회전축 양단에 슬러지를 안쪽으로 이송시키는 단위판상 스크류를 설치하고, 양측 단위판상스크류사이는 스프링상의 이송수단을 설치하여 슬러지의 체류시간을 증대시켜 건조 효율을 높히도록 함을 특징으로 한다.The present invention is to solve this problem, by installing a unit plate screw for transferring the sludge inwards on both ends of the rotary shaft of the stirring drying unit, between the unit plate screw on both sides by installing a spring transfer means to increase the residence time of the sludge to dry It is characterized by increasing the efficiency.

즉, 본 고안은 파형의 복사 건조판에 슬러지 이송수단으로 폐슬러지를 이송 건조시키는 이송장치에서, 회전축이 유착되는 하우징 내측대응부위에 회전축 보다 큰 직경으로된 중심축 양단 외주연에 슬러지를 안쪽으로 이송시키는 단위판상스크류를 설치하고, 양 단위판상스크류 사이에는 스프링상의 이송수단을 고정시킨 것이다.That is, the present invention is a conveying device for transporting and drying the waste sludge by the sludge transport means to the radiation drying plate of the corrugated wave, sludge inward on the outer periphery of the central shaft both ends of the diameter larger than the rotation shaft on the inner side of the housing to which the rotating shaft is bonded The unit plate screw for conveying is provided, and a spring-shaped conveying means is fixed between both unit plate screw.

이하 도면을 참조하여 상세히 설명하면 다음과 같다.When described in detail with reference to the drawings as follows.

제 3도는 본고안의 횡단면도로 파형의 복사건조판(220)에 슬러지 이송 수단으로 폐슬러지(240)를 이송 건조시키는 이송장치에서, 회전축(232)이 유착되는 하우징(300)내측 대응부위에 회전축(232) 보다 큰 직경으로된 중심축(235)양단 외주연에 슬러지(240)를 안쪽으로 이송시키는 단위판상스크류(241)를 설치하고, 양 단위판상스크류(241)사이에는 스프링상의 스프링스크류(250)로 된 이송수단을 고정시킨 것이다.3 is a cross-sectional view of the present invention in the transfer device for transporting and drying the sludge sludge 240 by the sludge transport means to the radiation drying plate 220 of the corrugated, the rotating shaft (232) in the housing 300, the inner side corresponding to the rotating shaft ( 232) a unit plate screw 241 for transporting the sludge 240 inwards on the outer periphery of both ends of the central shaft 235 having a larger diameter, and between the unit plate screw 241, a spring-like spring screw 250 It is fixed to the conveying means of).

상기 단위판상 스크류(241)는 양단이 상호 반대 방향을 이룸이 바람직한 바, 이는 슬러지(240)의 하우징(300)외부로의 누출을 막기위함이다. (251)은 슬러지를 단위건조판(221)에서 다음 단위건조판(221)으로 이송시키는 이송날개이다.The unit plate-shaped screw 241 is preferably both ends in the opposite direction, which is to prevent leakage of the sludge 240 to the outside of the housing 300. Reference numeral 251 denotes a transfer wing for transferring the sludge from the unit drying plate 221 to the next unit drying plate 221.

제 4도는 본 고안의 다른 예를 나타낸 횡단면도로, 제 3도에서의 이송수단인 스프링스크류(250)대신 스프링상브러쉬(260)로 구성한 것이고, 이송날개 역시 이송브러쉬(261)로 구성한 것이다.4 is a cross sectional view showing another example of the present invention, and is composed of a spring-like brush 260 instead of the spring screw 250, which is the conveying means in FIG. 3, and the conveying wing is also composed of the conveying brush 261.

이와같이 구성한 본 고안을 사용할 때에는 복사건조판(220)의 임의 단위건조판(221)에 슬러지가 공급되면 제 3도의 화살표와 같이 슬러지(240)가 좌측으로 이송하게 된다 .이는 회전축(232)이 반시계방향으로 회전하면 판상스크류(241) 및 스프링스크류(250)가 스크류 역할을 하여 슬러지(240)를 좌측으로 밀기 때문이다. 이때 스프링스크류(250)는 중심축(235)과는 일정직경만큼 공간을 두고 중심축을 감고 있는 상태이므로 탄력을 가지고 슬러지(240)를 이송시킬 수 있게 된다. 이렇게 하여 슬러지(240)를 좌측으로 이송시키면, 이송날개(251)가 삽과같이 회전하면서 슬러지를 다음 단위건조판(221)으로 이송시킨다. 그러면 다음번 회전축(232)에 의해 회전하는 스프링스크류(250)가 이번에는 화살표와 같이 슬러지(240)를 우측으로 이송시킨다. 이어 우측단에서는 역시 이송날개(251)가 다음번 단위건조판(221)으로 이송시킴을 반복한다. 이때 본 고안의 스프링스크류(250)는 슬러지(240)를 스크류 방향으로 순차 이송시킨 다음 이송날개(251)로 다음번 단위건조판(221)으로 이송시켜 다시 스크류 방향으로 이송시키기에 단위건조판(221)에 잔류하는 시간이 많아져서 건조효율을 증대시킨다 .아울러 스프링스크류(250)는 슬러지를 이송 가능한 면에만 스크류가 형성되어 있는 구조이므로 스크류 전체의 무게가 줄어들어 경제적이며 쿠션이 있어 내구성이 증대된다. 또한 단위판상스크류(241)는 중심측(235)양단에서 이송 방향이 상호 반대로 하여야 하는바, 이는 슬러지(240)가 하우징(300)의 회전축끼움공(310)을 통해 누출되는 것을 막기위함이고, 이송날개(251)를 통해 다음 건조판(221)으로 슬러지(240)가 잘 이송되게 하기 위함이다.When using the present invention configured as described above, if the sludge is supplied to the arbitrary unit drying plate 221 of the copy drying plate 220, the sludge 240 is transferred to the left side as shown by the arrow of FIG. 3. The rotating shaft 232 is half This is because the plate-shaped screw 241 and the spring screw 250 serve as a screw to push the sludge 240 to the left when rotated clockwise. At this time, the spring screw 250 is a state in which the central axis 235 is wound around the central axis with a space with a predetermined diameter, so that the sludge 240 can be transported with elasticity. In this way, when the sludge 240 is transferred to the left side, the feed blade 251 is rotated like a shovel to transfer the sludge to the next unit drying plate 221. Then, the spring screw 250 rotated by the next rotation shaft 232 this time transports the sludge 240 to the right as shown by the arrow. Subsequently, the transfer blade 251 is repeatedly transferred to the next unit drying plate 221 at the right end. In this case, the spring screw 250 of the present invention sequentially transfers the sludge 240 in the screw direction, and then transfers the sludge 240 to the next unit drying plate 221 with the transfer blade 251 to transfer the unit drying plate 221 again in the screw direction. The time remaining in the) increases the drying efficiency. In addition, the spring screw 250 has a structure in which a screw is formed only on a surface capable of transporting sludge. In addition, the unit plate-shaped screw 241 has to be opposite to each other in the conveying direction from the center side 235, which is to prevent the sludge 240 from leaking through the rotary shaft fitting hole 310 of the housing 300, This is to allow the sludge 240 to be well transferred to the next drying plate 221 through the transfer blade 251.

한편 본 고안은 슬러지의 점도 상태에 따라 이송 수단을 스프링상브러쉬(260)로 구현 할 수 있는 바, 이는 슬러지가 겔상태 또는 습기가 있는 그래뉼상태 일때 바람직하게 사용 가능하며 이송원리와 기능은 제 3도와 동일하므로 그 설명은 생략한다.Meanwhile, the present invention can implement the conveying means as a spring-like brush 260 according to the viscosity state of the sludge, which can be preferably used when the sludge is in the gel state or in the granulated state of the moisture, and the principle and function of the sludge is the third. This is the same as the description, so the description is omitted.

이상과 같이 본 고안은 슬러지를 스프링스크류 상태의 이송수단으로 순차 이송시키므로 슬러지가 건조판에 잔류하는 시간이 증대되어 건조 효율이 높고, 이송된 마지막 부분에는 반대 방향으로 이송하는 단위판상스크류와 이송날개에 의해 다음 건조판으로 슬러지를 용이하게 이송가능하다.As described above, the present invention sequentially transfers the sludge to the conveying means of the spring screw state, so that the time for which the sludge remains on the drying plate is increased, and the drying efficiency is high. The sludge can be easily transported to the next drying plate.
