Description

수중펌프의 슬러지 막힘 방지용 흡입커버 구조{Structure of Suction Cover for Preventing Sludge Clogging of Underwater Pump}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction cover for preventing the clogging of a sludge of a submersible pump,

본 발명은 수중펌프에 관한 것으로, 더욱 상세하게는 오폐수 처리장에서 수중펌프로 오폐수를 펌핑하는 동안 슬러지 등의 협잡물이 임펠러와 흡입커버 사이에 걸리지 않도록 하는 흡입커버 구조에 관한 것이다.The present invention relates to a submersible pump, and more particularly, to a suction cover structure that prevents impurities such as sludge from being caught between an impeller and a suction cover during pumping of wastewater by an underwater pump in a wastewater treatment plant.

일반적으로 수중펌프는 펌프와 이것을 구동하기 위한 전동기를 일체화한 것을 수중에 투입하여 양수할 수 있는 펌프이다. 수중펌프는 소형, 경량이며 취급이 쉽고, 프라이밍 조작이 필요 없는 등의 특징이 있으나 모터가 수중에 있기 때문에 그 봉입이나 누전 대책에 주의가 요구된다. 토목 공사 현장이나 샘물의 양수, 정수장, 폐수처리장, 또는 침수가 우려되는 지하실 또는 대량의 물을 담아두는 양어장 등 그 밖의 소수량 양수 시설에 널리 사용되고 있다. 특히 혼사 양송 등의 경우에는 내마모성 재료로 만들어진 수중 샌드 펌프가 이용되고 있다. 더욱이 수중펌프는 잠수형, 승하강형 및 지상설치형 등으로 분류된다.Generally, a submersible pump is a pump that can be pumped by putting a pump and an electric motor for driving it into the water. The submersible pump is small, light in weight, easy to handle, and does not require priming operation. However, since the motor is in water, care must be taken for its sealing and countermeasures against electric leakage. It is widely used in civil engineering work sites, pumping water for spring water, water treatment plants, wastewater treatment plants, basements where flooding is likely to occur, or other small-scale pumping stations such as fish farms containing large quantities of water. Especially, in the case of a marine mooring ship, an underwater sand pump made of an abrasion resistant material is used. Further, submersible pumps are classified into submersible type, submerged type and ground type.

종래의 수중펌프에서, 임펠러와 흡입커버 사이에 간격이 존재한다. 이러한 간격은 임펠러가 회전하는 동안 슬러지, 장갑, 노끈, 헝겊이나 행주 등의 이물질이 걸리게 되어 모터에 부하가 가중되어 모터의 정격전류보다 높은 전류가 인가되거나 모터의 소손으로 이어지는 원인으로 작용하였다. 또한, 임펠러와 흡입커버 사이에 걸린 이물질에 의하여 수중펌프의 양수능력에 미치지 못하는 문제와 더불어 양수를 위한 처리장의 처리능력 및 신뢰성이 저하되는 문제도 있었다.In a conventional submersible pump, there is a gap between the impeller and the suction cover. Such a gap is caused by foreign matter such as sludge, gloves, cord, cloth or cloth being caught while the impeller rotates, which causes a load higher than the rated current of the motor and causes the motor to be damaged. In addition, there is a problem that the foreign matter caught between the impeller and the suction cover does not reach the pump capacity of the underwater pump, and the processing ability and reliability of the treatment plant for the amniotic fluid are lowered.

이하, 본 발명에 따른 수중펌프의 슬러지 막힘 방지용 흡입커버 구조에 관하여 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, a suction cover structure for preventing sludge clogging of an underwater pump according to the present invention will be described in detail with reference to the accompanying drawings.

도 1에서, 수중펌프(1)는 모터와 임펠러가 내장된 케이스(2)가 구비되고, 케이스(2) 상부에 모터의 구동을 위하여 전원을 공급하는 전원케이블이 연결되는 덮개(3)가 일체 결합된다. 그리고 케이스(2) 아래에는 수중펌프(1)가 직립 유지되도록 하고 오폐수를 흡입하는 복수의 관통공이 형성된 지지대(4)가 결합된다. 또한, 케이스(2) 일측으로 흡입된 오폐수를 배출하는 엘보우관(5) 등을 통해 일정 길이의 배출관이나 배출호스가 연결될 수 있다.1, a submersible pump 1 is provided with a case 2 in which a motor and an impeller are incorporated, and a lid 3 to which a power cable for supplying power for driving a motor is connected is provided on the upper part of the case 2 . Below the case 2, a support table 4 having a plurality of through holes for sucking the wastewater is provided so that the underwater pump 1 is held upright. Further, a discharge pipe or discharge hose having a predetermined length may be connected through an elbow pipe 5 or the like for discharging wastewater sucked into one side of the case 2.

도 2 및 도 3에서, 수중펌프(1)의 케이스(2) 내측에는 모터(6)가 내장되고 모터(6)의 구동축(7)에는 임펠러(10)가 축 결합된다. 그리고 임펠러(10)가 설치된 케이스(2) 하부로 흡입커버(20)가 결합되고, 흡입커버(20) 아래로 지지대(4)가 결합된다. 수중펌프(1)의 케이스(2)는 다단으로 결합되되, 덮개(3), 엘보우관(5), 흡입커버(20) 등은 볼트공을 통해 볼트로 각각 고정 결합된다.2 and 3, a motor 6 is incorporated in the case 2 of the underwater pump 1 and the impeller 10 is axially coupled to the drive shaft 7 of the motor 6. The suction cover 20 is coupled to the lower portion of the case 2 in which the impeller 10 is installed and the support 4 is engaged under the suction cover 20. The lid 3, the elbow pipe 5, the suction cover 20, and the like are fixedly coupled to the case 2 of the underwater pump 1 by bolts through a bolt hole.

도 4에서, 임펠러(10)는 볼텍스 임펠러(Vortex Impeller)가 적용된다. 임펠러(10)는 원심형 펌프의 주요 부분으로 곡면을 지닌 블레이드(11)가 고정 결합된다. 임펠러(10)에 고정 결합된 블레이드(11)는 오폐수를 임펠러의 회전방향에 따라 그 중심에서 빨아 올려 블레이드를 통하여 바깥쪽으로 흐르도록 한다. 본 발명의 임펠러(10)는 단일의 블레이드로 구성되지만, 하나 이상의 블레이드가 일정 간격 및 곡률로 고정 결합된 것이 적용될 수 있다.In Fig. 4, the impeller 10 is a vortex impeller. The impeller 10 is fixedly coupled with a blade 11 having a curved surface as a main part of the centrifugal pump. The blade 11 fixedly coupled to the impeller 10 sucks the wastewater from the center thereof along the direction of rotation of the impeller and flows outwardly through the blades. Although the impeller 10 of the present invention is composed of a single blade, one or more blades fixedly coupled with a constant gap and a curvature may be applied.

흡입커버(20)는 대략 원통형으로 상하를 관통하는 흡입구(24)가 형성된 몸체(21)로 구성된다. 몸체(21) 하부 외측으로 일정 간격으로 볼트공(23)이 관통 형성된 플랜지(22)가 돌출 형성된다. 플랜지(22)의 볼트공(23)을 통해 케이스(2) 저면에 형성된 체결공(27)과 볼트(28)의 체결로 케이스(2)와 일체 결합된다. 몸체(21)에 관통 형성된 흡입구(24)는 상부 직경보다 하부 직경이 더 크게 형성된다.The suction cover (20) is composed of a body (21) having a substantially cylindrical shape and having a suction port (24) penetrating the upper and lower portions. A flange 22 formed with a bolt hole 23 penetrating through the lower portion of the body 21 at regular intervals is protruded. And is integrally coupled to the case 2 by fastening of the bolt 28 with the fastening hole 27 formed in the bottom surface of the case 2 through the bolt hole 23 of the flange 22. The suction port (24) formed through the body (21) has a lower diameter larger than an upper diameter.

몸체(21) 상부 중심에는 흡입구(24) 가장자리 상단으로 일정 간격으로 막힘방지벽(25)이 돌출 형성된다. 막힘방지벽(25)은 대략 6개로 구성되고, 막힘방지벽(25) 사이의 통로(26) 폭은 막힘방지벽(25)의 원호방향 길이보다 작게 형성되는 것이 좋다. 또한, 막힘방지벽(25) 사이의 통로(26)는 흡입구(24)로부터 흡입되어 배출되는 오폐수의 저항을 최소화할 수 구조, 예컨대, 막힘방지벽(25) 측면이 유선형으로 형성되는 것이 좋다.An anti-clogging wall 25 protrudes from the upper center of the body 21 at the upper end of the suction port 24 at regular intervals. The width of the passage 26 between the clogging prevention walls 25 is preferably smaller than the length of the clog prevention walls 25 in the circumferential direction. It is also preferable that the passage 26 between the clogging prevention walls 25 has a structure in which the resistance of the wastewater sucked and discharged from the suction port 24 can be minimized, for example, the side surface of the clogging prevention wall 25 is formed in a streamlined shape.

그리고 흡입커버(20)의 막힘방지벽(25) 외주면 외측으로 볼텍스 임펠러(10)의 하부 내측이 위치하여 결합된다.The lower inner side of the vortex impeller 10 is positioned and coupled to the outside of the outer peripheral surface of the clogging prevention wall 25 of the suction cover 20.

이와 같이 이루어진 본 발명의 수중펌프의 슬러지 막힘 방지용 흡입커버 구조에 의하면, 흡입커버(20)와 볼텍스 임펠러(10) 사이에 간극이 발생되지 않는다. 따라서 수중펌프(1)의 모터(6)의 작동으로 구동축(7)에 축 결합된 볼텍스 임펠러(10)가 회전하면서 지지대(4)의 통공과 흡입구(24)를 통해 오폐수를 흡입하면 블레이드(11) 내측에 위치한 흡입커버(20)의 막힘방지벽(25)과 볼텍스 임펠러(10)의 블레이드(11) 사이에 간극이 없어 간섭을 일으키지 않아 오폐수에 포함된 슬러지 등의 이물질이 걸리지 않게 된다.According to the suction cover structure for preventing clogging of sludge of the underwater pump of the present invention, a gap is not generated between the suction cover 20 and the vortex impeller 10. When the motor 6 of the submersible pump 1 operates to drive the vortex impeller 10 axially coupled to the drive shaft 7 and suck the wastewater through the through hole of the support 4 and the suction port 24, And the blades 11 of the vortex impeller 10 do not interfere with each other so that foreign matter such as sludge contained in the wastewater can not be caught.

그러므로 수중펌프(1)의 볼텍스 임펠러(10)와 흡입커버(20) 사이에 발생할 수 있는 이물질의 걸림이나 끼임을 방지하여 수중펌프(1)의 모터(6)에 과부하가 걸리지 않게 되고 정격전류가 인가되어 전력소모를 방지할 수 있다. 또한, 볼텍스 임펠러(10)와 흡입커버(20) 사이에 이물질이 걸리거나 끼이지 않아 오폐수의 배출량이 일정하다.Therefore, it is possible to prevent foreign substances from being caught or caught between the vortex impeller 10 and the suction cover 20 of the submersible pump 1 so that the motor 6 of the underwater pump 1 is not overloaded, Power consumption can be prevented. Further, since the foreign matter is not caught or caught between the vortex impeller 10 and the suction cover 20, the discharge amount of the wastewater is constant.

이상의 설명에서 본 발명은 특정의 실시 예와 관련하여 도시 및 설명하였지만, 청구범위에 의해 나타난 발명의 사상 및 영역으로부터 벗어나지 않는 한도 내에서 다양한 개조 및 변화가 가능하다는 것을 이 기술분야에서 통상의 지식을 가진 자라면 누구나 쉽게 알 수 있을 것이다.While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
