본 고안은 제조 및 환경분야 등에서 발생되는 슬러지를 원심력에 의한 비중차를 고형물과 액체로 분리시키도록 함과 더불어, 고형 미립자의 입자를 선별 처리할 수 있도록 한 고액(固液)분리기에 관한 것이다.The present invention relates to a solid-liquid separator capable of separating the sludge generated in the manufacturing and environmental fields, such as centrifugal force, into solids and liquids, as well as sorting solid particles.
일반적으로 슬러지는 오수처리가 공업폐수처리 등에서 대량으로 발생하며, 이러한 오수침전지와 같은 처리시설물에서 수거된 슬러지는 통상 90중량% 이상의 수분을 함유하고 있다.In general, sludge is generated in large quantities in industrial wastewater treatment and the like, and sludge collected in a treatment facility such as sewage sedimentation battery usually contains more than 90% by weight of water.
따라서 슬러지는 통상 고형화시켜 버리거나 태우기 때문에 가급적 충본히 탈수되어야 한다.Therefore, sludge is usually solidified or burned, so it must be dehydrated as much as possible.
특히, 연료를 더 필요로 하지 않고 소각시키거나 자발소각시키기 위해서는 슬러지의 함수량이 60중량% 이하, 바람직하게는 50중량% 이하가 되어야 한다.In particular, in order to incinerate or voluntarily burn without further fuel, the water content of the sludge should be 60% by weight or less, preferably 50% by weight or less.
종래에도 제조분야 및 환경분야 등에서 발생되는 여러 종류의 슬러지등을 처리하는 처리장지가 제안되고 있으나, 이는 주로 방대하고 시설투자비가 고가이므로 소규모의 슬러지를 탈수시키는 장치로는 부적합하였다.Conventionally, a treatment site for treating various types of sludge generated in manufacturing and environmental fields has been proposed, but this is not suitable as a device for dewatering small sludge since it is mainly enormous and expensive to invest in facilities.
따라서 최근에는 소규모의 슬러지등을 탈수하는 탈수장치가 이용되고 있긴 하지만 이는 소용량의 슬러지를 복잡한 구조 즉, 공급관을 통해 유입되는 슬러지가 원심력에 의해 외통 내부에 설치된 여과망에 찌꺼기(케익)는 흡착되고, 수분(액체)은 여과되면서 전방에 설치된 유압실린더 장치에 의하여 진퇴 작동하는 제거막이 여과망에 흡착된 찌꺼기를 탈락시켜 하부로 낙하된 찌꺼기를 수거하도록 구성하였으나, 찌꺼기를 제거하기 위하여는 별도의 기계적 단계 및 장치가 요구되었으며, 과다한 유지비용이 드는데 반하여 슬러지에 포함하고 있는 액체의 함량은 소량 감소시키는 정도로서 기대효과를 충족하지 못하였던 것이다.Therefore, in recent years, although a dewatering device for dewatering small sludges has been used, this means that a small amount of sludge has a complicated structure, that is, sludge flowing through a supply pipe is adsorbed to the filter network installed inside the outer cylinder by centrifugal force. While the water (liquid) was filtered, the removal membrane operating forward and backward by the hydraulic cylinder device installed at the front dropped the debris adsorbed to the filter network to collect the debris dropped to the bottom, but to remove the debris, a separate mechanical step and An apparatus was required, and excessive maintenance costs were required, while the amount of liquid contained in the sludge was reduced to a small extent, which did not meet the expected effect.
본 고안은 상기와 같은 제반결점을 감안하여, 이를 해소하기 위하여 슬러지의 양에 관계없이 슬러지를 탈수 및 분리하여 함수율이 낮은 고형분으로 처리하므로서 탈수효과의 증대와 더불어 취급을 용이하게 하고, 연속적인 처리 공정이 이루어지도록 하였으며, 슬러지에 포함되어 있는 고형미립자의 입자간 선별 처리가 가능하도록한 고액분리기를 제공하고자 하는데 고안의 목적이 있는 것이다.In order to solve this problem, the present invention dehydrates and separates the sludge irrespective of the amount of sludge to treat it as a solid content having a low moisture content, thereby increasing the dehydration effect and facilitating the handling, and continuous treatment. The purpose of the present invention is to provide a solid-liquid separator that allows the process to be made and enables the intergranular sorting treatment of the solid particles contained in the sludge.
상기의 목적을 이루기 위하여서는 슬러지를 장치내로 연속적으로 공급하여 주는 공급구와, 상기 공급구를 통해 공급된 슬러지를 분리 및 여과하는 여과스크린과. 상기 여과스크린에 의해 분리된 고형분 슬러지(케익)를 배출구측으로 이송, 배출하여 주는 스크류콘베이어와, 상기 여과스크린과 스크류콘베이어가 자별회전하도록 구동하여 주는 감속기가 결합 구성되어 상기 공급구를 통해 연속적으로 공급되는 슬러지를 고속회전하는 여과스크린의 원심력에 의한 비중차이로 고형물과 액체로 분리하고, 여과스크린에 의해 분리된 고형분슬러지는 감속기에 의해 감속회전하는 스크류콘베이어의 나사깃에 의해 여과스크린의 내벽에 퇴적되는 케익을 긁어 내어 배출구측으로 이송, 배출하도록 하므로서 연속적인 분리 및 탈수작업이 가능하도록 구성하고 있는 것이다.In order to achieve the above object, a supply port for continuously supplying sludge into the apparatus, and a filtration screen for separating and filtering the sludge supplied through the supply port. A screw conveyor for conveying and discharging the solid sludge (cake) separated by the filtration screen to the outlet side, and a reducer for driving the filter screen and the screw conveyor to rotate independently, are continuously supplied through the supply port. The sludge is separated into solids and liquids due to the specific gravity difference of centrifugal force of the filtering screen rotating at high speed. By scraping the cake to be transported and discharged to the outlet side, it is configured to enable continuous separation and dehydration work.
이하, 본 고안에 따른 고액분리기의 바림직한 일실시예를 첨부된 도면에 의거하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the solid-liquid separator according to the present invention will be described in detail with reference to the accompanying drawings.
첨부도면 제1도는 본 고안의 일실시예를 나타낸 전체사시도이고, 제2도는 제1도의 A-A선 단면도를 나타내고 있다.1 is an overall perspective view showing an embodiment of the present invention, Figure 2 is a cross-sectional view taken along line A-A of FIG.
본 고안의 고액분리기는 고액분리를 위한 스러지를 본체내로 공급하여 주는 공급구(10)를 설치하고, 상기 공급구(10)는 외주면에 나사깃(21)이 형성되며 일측단부에 다수개의 통공(22)이 형성되어 있는 스크류콘베이어(20)의 내측으로 공급하도록 접속되고, 상기 공급구(10)가 접속되는 스크류콘베이어(20)의 외주연부에 설치되는 여과스크린(30)과 슬러지챔버(40)는 스크류콘베이어(20)의 양측단으로 끼워져 고정되는 측면커버(23)(24)에 조립체결되어 모터(M)에 의해 고속회전하도륵 결합되어 있다.The solid-liquid separator of the present invention is provided with a supply port 10 for supplying the sludge for solid-liquid separation into the main body, the supply port 10 is formed with a screw feather 21 on the outer peripheral surface and a plurality of through holes ( The filter screen 30 and the sludge chamber 40 which are connected to supply the inner side of the screw conveyor 20 in which 22 is formed, are installed in the outer periphery of the screw conveyor 20 to which the said supply port 10 is connected. Is assembled to the side cover (23, 24) to be fitted and fixed to both ends of the screw conveyor 20 is coupled to rotate at high speed by the motor (M).
상기 여과스크린(30)은 제3도에 나타낸 바와 같이 상, 하판(31)(32) 사이에 이등변 삼각형상의 형태를 이루는 쐐기(33,33 :wedge)를 길이방향으로 세워지도록 일정간격으로 배열하여 원통체로 형성하되, 여과스크린(30)의 내측 원주면에는 폭(b)의 작은 장공(34)이 형성되고, 외측 원주면에는 폭(b')이 넓은 장공(35)을 갖는 웨지형스크린으로 형성하고 있다.As shown in FIG. 3, the filtration screen 30 is arranged at regular intervals so that the wedges 33 and 33: wedges forming an isosceles triangle shape between the upper and lower plates 31 and 32 are erected in the longitudinal direction. It is formed in a cylindrical body, the inner circumferential surface of the filter screen 30 is formed with a small long hole 34 of the width (b), the outer circumferential surface is a wedge-shaped screen having a long hole (35 ') wide width (b') Forming.
여과스크린(30)과 함께 스크류콘베이어(20)에 끼워지는 슬러지챔버(40)에는 슬러지배출공(41)을 형성하여 감속기(도시하지 않음)에 의해 감속회전하는 스크류콘베이어(20)의 회전에 따라 여과스크린(30)의 내벽면에 퇴적시킨 고형분슬러지를 상기 슬러지배출공(41)을 통하여 외부로 배출시키도록 하고 있다.A sludge discharge hole 41 is formed in the sludge chamber 40 fitted to the screw conveyor 20 together with the filtration screen 30 according to the rotation of the screw conveyor 20 which is decelerated and rotated by a reducer (not shown). The solid sludge deposited on the inner wall surface of the filtration screen 30 is discharged to the outside through the sludge discharge hole 41.
또한, 여과스크린(30)의 고속회전에 따라 분리된 액체(수분)와 고형분슬러지는 본체(50)에 형성되는 오수배츨구(51)와 슬러지배출구(52)를 통해 분리 및 수거하도록 구성되어 있는 것이다.In addition, the liquid (water) and the solids sludge separated by the high-speed rotation of the filtration screen 30 are configured to separate and collect through the wastewater discharge port 51 and the sludge discharge port 52 formed in the main body 50. .
첨부도면중 미설명 부호 53은 본체(50)의 내벽을 구획하는 격판을 의미하고 있다.Reference numeral 53 in the accompanying drawings denotes a diaphragm which divides the inner wall of the main body 50.
이와 같은 구성 결합된 본 고안의 고액분리기의 작용효과를 설명하면 다음과 같다.Referring to the effect of the solid-liquid separator of the present invention combined with such a configuration as follows.
즉, 공급구(10)를 통해 투입, 공급되는 슬러지는 감속회전하는 스크류콘베이어(20)의 통공(22)를 통해 여과스크린(30)측으로 비산 공급되면서 고속회전하는 여과스크린의 원심력에 의한 비중차이로 여과스크린의 내벽으로 흡착될때 슬러지에 함유된 수분은 장공(34.35)를 통해 외부로 빠져나가 본체(50)의 내벽면에 비산되어 분리 수거하게 되고, 여과스크린(30)에 흡착되는 고형슬러지는 감속기에 의해 저속회전하는 스크류콘베이어(20)의 회전에 따라 나사깃(21)에 의해 슬러지챔버(40)측으로 이동하여 슬러지배출공(41)과 본체(50)의 슬러지배출구(52)를 통해 수분이 제거된 고형슬러지를 수거할 수 있게 되는 것이다.That is, the sludge introduced and supplied through the supply port 10 is scattered and supplied to the filtration screen 30 through the through hole 22 of the screw conveyor 20 which is deceleratingly rotated, and thus the specific gravity difference by the centrifugal force of the filtration screen that rotates at high speed. Water adsorbed in the sludge when adsorbed to the inner wall of the furnace filtration screen is discharged to the outside through the long hole (34.35) is scattered on the inner wall surface of the main body 50 is collected separately, the solid sludge adsorbed to the filtration screen 30 As the screw conveyor 20 rotates at a low speed by the speed reducer, the screw blade 21 moves to the sludge chamber 40, and water is passed through the sludge discharge hole 41 and the sludge discharge port 52 of the main body 50. The removed solid sludge can be collected.
이상에서와 같이 본 고안에 따른 고액분리기는 감속회전하는 스크류콘베이어에 의해 여과스크린에 내벽에 슬러지를 비산시킨 다음, 여과스크린의 내벽에 비산된 슬러지는 고속회전하는 여과스크린에 의해 수분을 탈수 및 분리시키면서 탈수된 슬러지(케익)만을 흡착시키게 되고, 수분이 탈수된 고형분슬러지는 스크류콘베이어의 회전에 따라 외주면에 설치된 나사깃이 여과스크린의 내벽에 흡착된 슬러지를 슬러지챔버측으로 이송, 배출하게 되므로서 여과스크린에 고형슬러지가 적체되지 않게 되므로 연속적인 탈수 및 분리 작업이 이루어지게 되는 작용효과를 갖는 것이며, 여과스크린을 통상의 치차형태를 이루는 웨지형스크린으로 형성하고 있으므로 여과스크린의 내측 직경과 의측 직경이 서로 상이하여 고속으로 원심분리되는 슬러지가 내벽측장공을 통해 외측으로 비산될때 외벽측이 넓게 형성되어 있어 동일한 직경을 갖는 것에 비하여 보다 더 많은 수분을 신속하게 비산시킴으로서 탈수효과를 증대시키는 효과를 갖는 것이다.As described above, the solid-liquid separator according to the present invention scatters sludge on the inner wall of the filter screen by a screw conveyor rotating at a slow speed, and the sludge scattered on the inner wall of the filtering screen dehydrates and separates the water by the rotating filter screen at high speed. While dehydrated sludge (cake) is adsorbed, the solid sludge dehydrated is filtered as the screw blades installed on the outer circumferential surface of the sludge are transferred to and discharged from the inner wall of the filter screen to the sludge chamber as the screw conveyor rotates. Since solid sludge does not accumulate on the screen, it has the effect of continuous dehydration and separation work, and since the filter screen is formed as a wedge-shaped screen that forms a normal gear shape, the inner and side diameters of the filter screen Sludge which is different from each other and centrifuged at high speed When scattering to the outside through the slot with the outer wall side has become widely formed to have an effect of rapidly increasing the scattering sikimeuroseo dehydrating effect more moisture than compared to having the same diameter.
또한, 여과스크린에 일정한 간격으로 배열 고정되는 쇄기간의 간격(폭)을 조정하거나 간격이 서로 다른 여러종류의 여과스크린을 구비하였을 때에는 여과스크린에 흡착되는 슬러지의 입자를 선별 처리할 수 있게 되므로 여과스크린의 교환에 따라 고형미립자에서 부터 초미립자의 입자를 선별적으로 처리할 수 있고, 이러한 본 고안의 고액분리기는 폐수처리 및 분뇨종말처리에서 부터 식품공장의 찌꺼기 및 생활하수의 쓰레기 및 오니등을 분리, 수거하는데 매우 효과적으로 이용, 대처할 수 있는 등의 잇점을 갖는 것으로, 산업상의 이용가치가 크고 매우 실용적이며 유용한 고안이다.In addition, when adjusting the interval (width) of the chain period that is fixed to the filter screen at regular intervals, or when equipped with different types of filter screens having different intervals, the particles of sludge adsorbed on the filter screen can be sorted. By changing the screen, ultra-fine particles can be selectively processed from solid particles, and the solid-liquid separator of the present invention separates wastes and sludges from food plant and sewage from waste water treatment and manure end treatment. It has the advantage of being able to use and cope very effectively to collect, and has a high industrial value and a very practical and useful design.
