본 발명은 수중 스크루 펌프용 임펠러 구조에 관한 것으로, 상세하게는 축사나 돈사의 분뇨처리를 위해 고형물을 효율적으로 이송할 수 있도록 하는 수중 스크루 펌프용 임펠러 구조에 관한 것이다.
The present invention relates to an impeller structure for underwater screw pumps, and more particularly, to an impeller structure for underwater screw pumps to efficiently transport solids for manure treatment of barns or pigs.

일반적으로 축사에서 가축들이 배설하는 폐수는 분과 뇨 그리고 가축들에게 공급되는 물로 이루어지는데, 이러한 폐수들은 단계적인 장치를 이용하여 분에서 뇨(오수)를 각각 분리시킨 후 처리하도록 되어 있는데, 그 이유는 가축의 분뇨를 하천에 방류시키게 되면 하천을 오염시키는 주요 원인이 되므로 별도의 정화설비를 이용하여 처리토록 되어 있다.In general, the livestock excreted in livestock houses consists of manure, urine, and water supplied to livestock. These waste waters are processed by separating the urine (sewage) from the manure by means of a staged device. Discharge of livestock manure into rivers is a major cause of pollution and is treated with a separate purification facility.

근래에는 상기와 같은 문제점을 해결하기 위해서 여러 종류의 분뇨처리방법 즉 고형분과 액체를 분리하여 별도 저장하는 고액 분리식 처리방법과, 발효물질(톱밥)에 배양재를 투입하여 미생물을 번식하게 하여 처리하는 발효 처리식, 탱크에 저장하였다가 필요시에 사용하는 액비 저장식, 정화시설에 의한 정화처리장치 등 여러 방식의 처리방법이 사용되고 있다.Recently, in order to solve the above problems, various kinds of manure treatment methods, that is, solid-liquid separation treatment method for separately storing solids and liquids, and injecting a culture material into fermentation material (sawdust) to propagate microorganisms Various methods have been used, such as fermentation treatments, liquid storage stored in tanks and used when needed, and purification apparatuses using purification facilities.

특히 이러한 가축의 분뇨는 수중펌프를 이용하여 저장조에서 배수하도록 하고 있으나 가축의 분뇨의 특성상 점도가 높고 이물질이 많이 섞여 있어서 원활하게 배수를 수행하기 어려울 뿐만 아니라 배수 임펠러와 커버 사이에 이물질 등이 쉽게 걸려 임펠러의 회전을 방해하는 경우가 수시로 발생하고 이로 인하여 모터에 과부하가 걸려 모터를 훼손시키는 문제점이 있었다.In particular, the manure of the livestock is to be drained from the storage tank by using an underwater pump, but due to the nature of the manure of the livestock, it is difficult to perform the drainage smoothly due to the high viscosity and mixed of foreign matters, as well as the foreign matter easily caught between the drainage impeller and the cover. The impeding the rotation of the impeller often occurs, thereby overloading the motor there was a problem to damage the motor.

도 1 은 종래의 수중 스크루 펌프용 임펠러를 나타낸 사시도이고, 도 2 는 종래의 수중 스크루 펌프용 임펠러를 나타낸 정면도이다.1 is a perspective view showing a conventional underwater screw pump impeller, Figure 2 is a front view showing a conventional underwater screw pump impeller.

도 1 과 도 2 에 나타낸 바와 같이, 종래의 수중 스크루 펌프용 임펠러(1)는 회전플레이트(10)의 저면에 원호상으로 돌출시킨 한 쌍의 블레이드(20)를 하향으로 형성하여 구성한 것으로, 회전플레이트(10)의 회전으로 한 쌍의 블레이드(20)가 회전하면서 축사나 돈사의 폐수를 배출할 수 있도록 한다.As shown in Fig. 1 and Fig. 2, the conventional underwater screw pump impeller 1 is formed by forming a pair of blades 20 protruding downward in an arc shape on the bottom of the rotating plate 10, the rotation Rotation of the plate 10 allows the pair of blades 20 to rotate to discharge the waste water from the barn or pig house.

그러나 이러한 종래의 기술은 회전플레이트(10)와 커버 사이에 폐수의 이물질이 수시로 걸려 회전이 원활하지 못할 뿐만 아니라 심지어 임펠러(1)가 멈추는 경우가 발생하여 모터에 과부하가 걸리게 되고 이로 인하여 모터가 훼손될 우려가 높을 뿐만 아니라 폐수의 배수가 원활하지 못한 문제점이 있었다.However, this conventional technology is not only smooth rotation due to foreign matter caught in the waste water between the rotating plate 10 and the cover, but also the case where the impeller 1 is stopped, the motor is overloaded, thereby damaging the motor. Not only was there a high concern, but there was a problem that the drainage of wastewater was not smooth.

한편, 수중 임펠러에 관련하여 특허등록 제10-1204381호도 있다.
On the other hand, there is also a patent registration No. 10-1204381 related to the underwater impeller.

따라서 본 발명의 주목적은 축사나 돈사 등의 점도가 높고 이물질이 많이 함유된 고농도 폐수를 원활하게 배수할 수 있도록 하는 수중 스크루 펌프용 임펠러 구조를 제공하는 데 있다.Accordingly, an object of the present invention is to provide an impeller structure for an underwater screw pump that can smoothly drain high-concentration wastewater containing a high viscosity such as barns or pigs and containing a large amount of foreign substances.

본 발명의 다른 목적은 고농도 폐수에 함유된 이물질을 효율적으로 분쇄할 수 있도록 하여 이물질로 인한 걸림을 억제하고 이로 인하여 과부하를 방지하여 모터를 보호할 수 있도록 하는 수중 스크루 펌프용 임펠러 구조를 제공하는 데 있다.
Another object of the present invention is to provide an impeller structure for an underwater screw pump that can effectively crush the foreign matter contained in the high concentration wastewater to suppress the jam caused by the foreign matter and thereby prevent the overload to protect the motor have.

상기한 문제점을 해소하기 위하여 본 발명의 수중 스크루 펌프용 임펠러 구조는 회전플레이트의 저면에 한 쌍의 블레이드를 하향으로 형성하고 블레이드를 회전플레이트 중심부에서부터 회오리형상으로 형성하며 한 쌍의 블레이드 사이에 중심에서부터 점진적으로 깊어지는 가이드홈을 형성하고 블레이드를 외향으로 기울게 하여 경사면을 형성하도록 하되 블레이드를 점진적으로 세워 최외각에서는 수직 상태를 유지하도록 구성함을 그 기술적 구성상의 기본특징으로 한다.
In order to solve the above problems, the impeller structure for the underwater screw pump of the present invention forms a pair of blades downward on the bottom of the rotating plate, and forms the blade in a toroidal shape from the center of the rotating plate, and from the center between the pair of blades. The basic feature of the technical configuration is to form a guide groove that is gradually deepened and to form an inclined surface by tilting the blade outward, but to keep the blade vertically at the outermost angle.

따라서 본 발명의 수중 스크루 펌프용 임펠러는 먼저, 모터를 구동하여 임펠러의 고속으로 회전시키면 축사나 돈사 등의 점도가 높고 이물질이 많이 함유한 고농도 폐수를 가이드홈을 통하여 원활하게 배수할 수 있도록 유도하는 것으로, 블레이드를 회오리형상으로 형성하고 가이드홈을 점진적으로 깊어지도록 하며 블레이드를 외향으로 기울게 하여 경사면을 형성하므로, 고농도 폐수를 더욱 원활하게 배출할 뿐만 아니라 커버와 임펠러 사이에 끼는 고농도 폐수의 이물질을 효율적으로 그라인딩하여 제거하므로 배수효율을 크게 향상시키고 모터의 과부하를 억제하여 기기의 수명을 연장할 수 있는 효과가 있는 것이다.
Therefore, the impeller for underwater screw pump of the present invention first drives the motor to rotate at high speed of the impeller to induce a high concentration of wastewater such as barns or pigs, and high concentration wastewater containing a large amount of foreign substances to smoothly drain through the guide grooves. Since the blades are formed in a whirlwind shape, the guide grooves are gradually deepened, and the blades are inclined outward to form an inclined surface, which not only discharges the high concentration wastewater more smoothly, but also effectively removes foreign substances in the high concentration wastewater that are sandwiched between the cover and the impeller. Grinding is removed by grinding, which greatly improves drainage efficiency and suppresses the overload of the motor, thereby extending the life of the equipment.

이하, 본 발명의 실시 예를 첨부한 도면을 참조하면서 상세하게 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 3 내지 6 에 나타낸 바와 같이, 본 발명의 수중 스크루 펌프용 임펠러(1) 구조는 회전플레이트(10)의 저면에 하향으로 돌출시킨 한 쌍의 블레이드(20)를 형성하되, 상기 한 쌍의 블레이드(20)를 회전플레이트(10) 중심부에서부터 회오리형상으로 형성하고, 한 쌍의 블레이드(20) 사이에 중심에서부터 점진적으로 깊어지는 가이드홈(21)을 형성하며, 블레이드(20)를 외향으로 기울게 하여 경사면(22)을 형성하도록 하되 블레이드(20)를 점진적으로 세워 최외각에서 수직 상태를 유지하도록 구성한다.As shown in Figures 3 to 6, the underwater screw pump impeller 1 structure of the present invention forms a pair of blades 20 protruding downward on the bottom surface of the rotating plate 10, the pair of blades 20 is formed in a toroidal shape from the center of the rotating plate 10, and forms a guide groove 21 which gradually deepens from the center between the pair of blades 20, and tilts the blades 20 outward to the inclined surface. To form (22) but to gradually build the blade 20 is configured to maintain the vertical state at the outermost.

상기 회전플레이트(10)는 모터의 회전축에 연결하여 고속으로 회전시킬 수 있도록 원판형으로 형성한다.
The rotating plate 10 is formed in a disk shape so as to be connected to the rotating shaft of the motor to rotate at high speed.

상기 블레이드(20)는 한 쌍으로 구성하되 회전플레이트(10) 중심부에서부터 회오리형상으로 형성하여 축사나 돈사 등의 점도가 높고 이물질이 많이 함유된 고농도 폐수를 원활하게 배수할 수 있도록 함이 바람직하다.The blade 20 is composed of a pair, but from the center of the rotating plate 10 is formed in a whirlwind shape, it is preferable to smoothly drain the high concentration wastewater containing a high viscosity and a lot of foreign matter such as barns or pigs.

더욱이, 한 쌍의 블레이드(20) 사이에 공간에는 중심에서부터 점진적으로 깊어지는 가이드홈(21)을 형성하여 고농도 폐수를 더욱 원활하게 배수할 수 있도록 한다.Furthermore, a guide groove 21 is formed in the space between the pair of blades 20 to gradually deepen from the center to more smoothly drain the high concentration wastewater.

아울러, 블레이드(20)를 외향으로 기울게 하여 경사면(22)을 형성하여 회전플레이트(10)의 회전에 따른 원심력을 효율적으로 작용하도록 하므로 고농도 폐수를 더욱더 원활하게 배수할 수 있도록 한다. In addition, by inclining the blade 20 outward to form an inclined surface 22 to effectively operate the centrifugal force according to the rotation of the rotating plate 10 to allow the high concentration wastewater to be more smoothly drained.
