Description
본 발명은 압하량 조절이 가능한 탈수장치에 관한 것으로서, 보다 상세하게는 슬러지를 압착하는 상부롤부에 압하량을 조절하는 장치를 체결하여 슬러지의 탈수율을 높일 수 있는 압하량 조절이 가능한 탈수장치에 관한 것이다.The present invention relates to a dewatering apparatus capable of adjusting the amount of pressing down, and more particularly, to a dehydrating apparatus capable of adjusting the amount of pressing down to increase the dewatering rate of the sludge by fastening a device for adjusting the amount of pressing down on the upper roll portion for pressing the sludge. It is about.
일반적으로 도 1에 도시된 바와 같이, 연주공장에서 사용된 냉각수(1)는 배관을 통하여 침전조(2)에 유도되어 슬러지(3)를 침전시키게 된다. 즉, 침전조(3)로 유도된 냉각수(1)는 미립자를 포함하고 있으므로 침전조(2)에 유도되어 시간이 경과되면 미립자의 비중에 의하여 침전조(2) 하부로 침전하게 되어 슬러지(3)를 형성하게 된다.In general, as shown in Figure 1, the cooling water 1 used in the regeneration plant is guided to the settling tank 2 through the pipe to precipitate the sludge (3). That is, since the cooling water 1 guided to the settling tank 3 contains fine particles, the coolant 1 is guided to the settling tank 2 and, over time, precipitates under the settling tank 2 due to the specific gravity of the fine particles to form sludge 3. Done.
상기와 같이 미립자가 침전된 다음, 슬러지(3) 상부의 폐수는 배출시켜 재활용하거나 폐수처리장으로 이송되어 지며, 슬러지(3)는 배출관(4)을 통하여 시그너 드라이버(5)로 이송되며, 이송된 슬러지는 시그너 드라이버(5)에서 다시 침전되어 응고되면 배출이 불가능하므로 시그너 드라이버(5) 내부에 설치된 교반기(6)로 항시 교반시켜 응고현상을 방지한다.After the fine particles are precipitated as described above, the waste water of the upper portion of the sludge (3) is discharged and recycled or transported to the waste water treatment plant, the sludge (3) is transferred to the signer driver (5) through the discharge pipe (4), When the sludge is precipitated in the signer driver 5 and solidified again, it is impossible to discharge the sludge.
상기와 같이 교반된 슬러지(3')를 하방에 설치된 벨트 프레스형 탈수장치(10)로 이송하여 탈수를 실시하는데, 벨트 프레스형 탈수장치(10)는 도입하는 이유는 시그너 드라이버(5)에서 교반되어 배출된 슬러지의 경우 미립자보다는 냉각수 성분이 현저히 많기 때문에 벨트 프레스형 탈수장치를 이용하여 냉각수 성분과 미립자 성분을 분리하게 하는 것이다.The agitated sludge 3 'is transferred to a belt press type dewatering device 10 installed below to perform dehydration. The reason for introducing the belt press type dewatering device 10 is from the signer driver 5. In the case of the sludge discharged by stirring, since the cooling water component is significantly higher than the fine particles, the belt press type dehydrator is used to separate the cooling water component and the particulate component.
종래의 벨트 프레스형 탈수장치(10)는 단순히 상부 구동롤(11)에 연결된 벨트(12)의 압하력에 의하여 냉각수(1')는 측부로 흐르게 되고, 슬러지(3')만 압하되어 배출호퍼(13)로 낙하하게 되며, 호퍼(13)로 낙하된 슬러지(3')는 이송수단(14)에 의하여 운반되어 폐기물로서 매립되어 처리된다.In the conventional belt press type dewatering device 10, the cooling water 1 'flows to the side by simply pressing down the belt 12 connected to the upper drive roll 11, and only the sludge 3' is pressed down to discharge the hopper. The sludge 3 'dropped into the hopper 13 is transported by the conveying means 14 to be landfilled and disposed of as waste.
또한, 탈수된 폐수(1')는 폐수집수 탱크(16)로 집수되어 펌프(17)에 의해서 다시 침전조(2)로 유입되어 상기와 같은 탈수공정을 거치게 된다.In addition, the dewatered wastewater 1 'is collected by the wastewater collection tank 16 and flows back into the settling tank 2 by the pump 17 to undergo the dehydration process as described above.
그러나, 종래의 벨트 프레스형 탈수장치(10)는 가동시간에 비해 효율이 떨어지고, 상부롤부의 종동롤(15)의 압하량 조절이 불가능하여 탈수된 슬러지(3')에도 다량의 수분이 함유되어 있어 이송이나 운반시 주위환경이 오염되는 문제점이 발생한다.However, the conventional belt press type dewatering device 10 is inferior in efficiency compared to the operation time, and it is impossible to control the rolling amount of the driven roll 15 of the upper roll part, so that the dewatered sludge 3 'contains a large amount of water. There is a problem that the surrounding environment is polluted during transport or transportation.
또한, 구동롤(11)의 회전만으로 벨트(12)를 회전시켜 압하하므로 구동롤(11)에 상당한 부하가 걸려 설비고장의 원인이 되며, 다량의 슬러지가 상기 탈수장치(10)로 인입되면 비중이 증가되어 양측의 롤에 의해서 지지된 탈수벨트가 하부로 처지는 현상이 발생하여 탈수효율이 저하되고, 더 나아가 탈수가 불가능해지는 문제점이 있다.In addition, since the belt 12 is rotated and reduced only by the rotation of the driving roll 11, a considerable load is applied to the driving roll 11, causing a malfunction of the equipment, and when a large amount of sludge is introduced into the dehydration apparatus 10, the specific gravity There is a problem that the increase in the dehydration belt supported by the rolls on both sides is sagging to lower the dewatering efficiency, further dehydration is impossible.
상기와 같은 문제점을 해결하기 위하여 도출된 본 발명은 상부롤부에 유압실린더를 구비하여 압하력이 부가되고, 상부 및 하부 벨트컨베이어의 구동롤과 종동롤 사이에 다수개의 지지롤을 구비하여 벨트 처짐현상을 방지하여 탈수효율을 높이고, 설비 고장율을 감소시키는 압하량 조절이 가능한 탈수장치를 제공하는데 그 목적이 있다.The present invention derived to solve the above problems is provided with a hydraulic cylinder in the upper roll portion is added to the pressing force, the belt deflection phenomenon is provided with a plurality of support rolls between the driving roll and the driven roll of the upper and lower belt conveyor The purpose of the present invention is to provide a dehydration apparatus capable of adjusting the amount of reduction to increase the dewatering efficiency by reducing the failure rate, and to reduce the failure rate of equipment.

이하, 첨부된 도면에 의거하여 본 발명은 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 압하량 조절이 가능한 탈수장치의 전체구성 및 탈수공정을 나타내는 개략도이며, 도3은 본 발명에 따른 압하량 조절이 가능한 탈수장치의 부분 정면도이다.Figure 2 is a schematic diagram showing the overall configuration and the dehydration process of the dehydration apparatus capable of adjusting the reduction amount according to the present invention, Figure 3 is a partial front view of the dehydration apparatus capable of adjusting the reduction amount according to the present invention.
도 2 내지 3에 도시된 바와 같이, 본 발명에 따른 압하량 조절이 가능한 탈수장치는 냉각수(1)를 집수하여 침전조(2)에서 1차 침전을 하여 침전된 슬러지(3)를 상기 침전조(2) 하방에 설치된 재침전조(20)에 배출시켜 2차 침전을 실시한다.As shown in Figures 2 to 3, the dewatering device capable of adjusting the reduction in pressure according to the present invention collects the cooling water (1) to the primary sedimentation in the sedimentation tank (2), the sludge (3) precipitated in the sedimentation tank (2) ) Secondary precipitation is carried out by discharging to the reprecipitation tank 20 installed below.
즉, 상기 1차 침전조(2)에 집수되어 소정의 시간이 경과하면 냉각수(1)에 함유된 각종 미립자는 침전하고, 침전된 슬러지 상부에는 비교적 오염도가 적은 폐수가 미립자와 분리되어 나타나는데, 이 때 각종 미립자가 분리된 폐수는 배출되어 폐수정화시설로 이송하게 된다.That is, when a predetermined time elapses after being collected in the primary sedimentation tank 2, various fine particles contained in the cooling water 1 precipitate, and the sewage sludge is separated from the fine particles of the waste water having a relatively low pollution. Wastewater from which various particulates are separated is discharged and transferred to a wastewater purification facility.
상기 1차 침전조(2)에서 침전된 슬러지(3)는 침전조(2) 하단에 구비된 배출구(4)를 통하여 재침전조(20)로 배출되는데, 재침전조(20)는 1차 침전된 슬러지(3)를 2차 침전시켜 1차 침전된 슬러지(3)보다는 수분함유도가 감소된 슬러지(20')로 침전시켜 탈수효율을 높이기 위함이다.The sludge (3) precipitated in the primary settling tank (2) is discharged to the reprecipitation tank 20 through the outlet 4 provided at the bottom of the settling tank (2), the reprecipitation tank 20 is the primary precipitated sludge ( This is to increase the dehydration efficiency by precipitating 2) to 2nd settling sludge (20 ') which has a reduced water content than the 1st settled sludge (3).
상기와 같이 재침전조(20)에서 침전된 슬러지(20')는 폐수와 2차 침전된 슬러지로 분리되는데, 폐수는 상기 1차 침전에서와 같이 상부에 설치된 배수시설(22)에서 배수되어 폐수정화시설로 배출되어 지며, 2차 침전된 슬러지(20')는 재침전조(20) 하부에 구비된 배출구(23)까지 상향에서 사각으로 관통하고 있는 스크류 컨베이어(24)를 통하여 배출된다.As described above, the sludge 20 'precipitated in the reprecipitation tank 20 is separated into wastewater and secondary precipitated sludge, and the wastewater is drained from the drainage facility 22 installed in the upper portion as in the first precipitation. It is discharged to the facility, the secondary precipitated sludge 20 'is discharged through the screw conveyor 24 penetrating in a square from up to the discharge port 23 provided in the reprecipitation tank 20.
여기에서, 스크류 컨베이어(24)를 배출수단으로 이용하는 이유는 2차 침전된 슬러지(20')는 수분함유도가 상대적으로 낮아 배출구(23)를 통한 자연 배출이 난이하며, 또한 배출된 2차 침전 슬러지(20')에 포함된 수분을 더욱 감소시키기 위하여 2차 침전된 슬러지(20')의 배출은 하향으로 경사지게 설치된 스크류 컨베이어(24)를 통하여 탈수장치로 배출을 유도한다.Here, the reason why the screw conveyor 24 is used as a discharge means is that the secondary precipitated sludge 20 'has a relatively low water content, which makes it difficult to naturally discharge through the discharge port 23 and discharged secondary precipitates. In order to further reduce the water contained in the sludge 20 ', the discharge of the secondary precipitated sludge 20' leads to discharge to the dewatering device through the screw conveyor 24 installed to be inclined downward.
상기 스크류 컨베이어(24)를 통하여 배출된 슬러지(20')는 상부 벨트컨베이어부(31)와, 하부 벨트컨베이어부(41)로 구성된 슬러지 탈수장치의 하부 벨트컨베이어부(41)에 낙하되도록 구성한다.The sludge 20 ′ discharged through the screw conveyor 24 is configured to fall on the lower belt conveyor part 41 of the sludge dewatering device composed of the upper belt conveyor part 31 and the lower belt conveyor part 41. .
즉, 탈수장치는 상부 벨트컨베이어부(31)가 하부 벨트컨베이어부(41)로 배출된 슬러지(20')를 압착함으로 슬러지(20'')에 포함된 수분을 탈수하는 원리로서, 하부 벨트컨베이어부(41)가 상부 벨트컨베이어부(31)보다는 슬러지 인입할 수 있도록 더 길게 형성되어 있다.That is, the dewatering device is a principle of dewatering the water contained in the sludge 20 '' by compressing the sludge 20 'discharged to the lower belt conveyor portion 41 by the upper belt conveyor portion 41, the lower belt conveyor The portion 41 is formed longer than the upper belt conveyor portion 31 to allow sludge inlet.
상기 하부 벨트컨베이어부(41)의 구동력을 부여하는 구동롤(42)은 측부에 고정장착된 전동모터(43)의 감속기(43')가 구비된 구동축(44)과 베어링 블록(45)에 의하여 축결합하여 구동되며, 벨트(46)의 텐션조정은 슬러지 인입부에 설치된 종동롤(47)의 위치를 고정프레임(48) 상에서 좌우 이동시킴으로써 가능하게 된다.The driving roll 42 which imparts the driving force of the lower belt conveyor portion 41 is driven by the drive shaft 44 and the bearing block 45 provided with the reduction gear 43 'of the electric motor 43 fixedly mounted to the side. Driven by shaft coupling, tension adjustment of the belt 46 is made possible by moving the position of the driven roll 47 provided in the sludge inlet part on the fixed frame 48 left and right.
또한, 상기 하부 벨트컨베이어부(41)는 구동롤(42)과 종동롤(47) 사이에 회전벨트(46)를 지지하는 다수개의 지지롤(49)이 고정프레임(48) 상에 회동가능하도록 설치되는데, 상기 지지롤(49)은 슬러지 압착시 발생되는 벨트(46)의 처짐현상을 극복하기 위하여 구비된다.In addition, the lower belt conveyor portion 41 has a plurality of support rolls 49 supporting the rotating belt 46 between the driving roll 42 and the driven roll 47 so as to be rotatable on the fixed frame 48. Is installed, the support roll 49 is provided to overcome the deflection phenomenon of the belt 46 generated during the sludge compression.
상기 지지롤(49)을 설치하는데 있어서, 중요한 사항은 슬러지 인입부의 종동롤(47)에서 슬러지 배출부의 구동롤(42)까지 설치되는 지지롤(49)의 직경이 구동롤(42) 쪽으로 갈수록 더 적은 직경의 지지롤(49)을 설치한다는 것이다.In the installation of the support roll 49, an important point is that the diameter of the support roll 49, which is installed from the driven roll 47 of the sludge inlet part to the drive roll 42 of the sludge discharge part, becomes more toward the driving roll 42. It is to install a support roll 49 of a small diameter.
이러한 이유는 구동롤(42) 및 종동롤(47)의 직경과 같은 직경의 지지롤을 설치하는 경우, 롤과 롤의 사이 간격이 넓어질 수밖에 없기 때문에 슬러지 압착시 벨트 처짐현상이 발생하게되어 탈수효율이 감소하는 점을 감안하여 구동롤(42) 쪽으로 갈수록 더 작은 직경의 지지롤(49)을 이용함으로써 롤과 롤 사의 간격을 줄여 벨트 처짐현상을 방지하기 위함이다.The reason for this is that when the supporting rolls having the same diameter as the driving roll 42 and the driven roll 47 are installed, the gap between the rolls and the rolls must be widened, causing the belt to sag when the sludge is pressed and dewatering. In order to prevent the belt from sagging by reducing the gap between the roll and the roll yarn by using the support roll 49 having a smaller diameter toward the driving roll 42 in view of the efficiency is reduced.
다시 설명하면, 직경이 동일한 롤을 지지롤로서 배치할 경우 롤과 롤 사이에 탈수되어지는 슬러지가 위치하게 되므로 압하된 슬러지에 의해 벨트 변형이 일어나 탈수효율이 저감됨과 동시에 변형된 벨트를 빈번히 교체하여야 하고, 더 나아가 구동롤에 과중한 부하가 발생하기 때문에 상기와 같이 구동롤 쪽으로 갈수록 점진적으로 더 작은 직경의 지지롤을 설치하게 되는 것이다.In other words, when a roll having the same diameter is disposed as a supporting roll, sludge to be dewatered is positioned between the roll and the roll, so that the belt is deformed by the pressed sludge, which reduces the dewatering efficiency and frequently changes the deformed belt. In addition, since a heavy load is generated on the driving roll, the supporting roll of a smaller diameter is gradually installed toward the driving roll as described above.
상기 하부 벨트컨베이어부(41)를 압하하여 슬러지(20')를 압착하는 상부 벨트컨베이어부(31)는 상기 하부 벨트컨베이어부(41)와 같은 방식으로 고정프레임(32)에 지지롤(33)을 구동롤(34)과 종동롤(35) 사이에 구비하게 되며, 상기 구동롤(34)은 일측의 고정베이스(54,54') 상에 고정장착된 전동모터(40)의 감속기(40')를 구비한 구동축(51)이 베어링 블록(52, 53)으로 결합하여 구동력을 부여받아 상부 벨트컨베이어부(31)를 회동가능하도록하며, 상기 구동롤(34) 상부에 텐션롤(36)을 고정베이스(38)에 체결하여 동 텐션롤(36)을 상향 또는 하향 조정함으로써 상부 벨트컨베이어부(31)의 벨트(37)를 텐션조정하게 된다.The upper belt conveyor portion 31 for pressing the sludge 20 'by pressing the lower belt conveyor portion 41 is supported on the fixing frame 32 in the same manner as the lower belt conveyor portion 41. It is provided between the drive roll 34 and the driven roll 35, the drive roll 34 is the reduction gear 40 'of the electric motor 40 fixedly mounted on the fixed base (54, 54') on one side Drive shaft 51 having a) is coupled to the bearing block (52, 53) to give a driving force to the upper belt conveyor portion 31 is rotatable, the tension roll 36 on the drive roll 34 The belt 37 of the upper belt conveyor part 31 is tensioned by tightening the tension roll 36 upwardly or downwardly by fastening to the fixed base 38.
상기 상부 벨트컨베이어부(31)는 하부 벨트컨베이어부(41)를 압하하므로 상기 하부 벨트컨베이어부(41)와 같이 벨트변형이 일어나게 된다. 따라서, 상기 하부 벨트컨베이어부(41)와 같은 원리로서 구동롤(34)과 종동롤(35) 사이에 구동롤(34) 쪽으로 갈수록 더 작은 직경의 지지롤(33)을 고정프레임(32)에 설치하여 컨베이어벨트(37)를 지지함으로써 롤과 롤 사의 간격을 줄여 상부 벨트의 변형을 방지하게 된다.Since the upper belt conveyor part 31 pushes down the lower belt conveyor part 41, belt deformation occurs like the lower belt conveyor part 41. Therefore, as the lower belt conveyor portion 41, the support roll 33 of the smaller diameter between the driving roll 34 and the driven roll 35 toward the driving roll 34 in the fixed frame 32 By installing and supporting the conveyor belt 37, the gap between the roll and the roll is reduced to prevent deformation of the upper belt.
