3 : 블레이드 팁 4 : 튀김방지판3: blade tip 4: splash prevention plate
본 고안은 하수 및 폐수처리 장치의 표면포기기용 임펠러에 관한것으로 특히 수면의 반사파동에 의한 충격을 최소화하면서 일정수위 범위내에서 수위가 변하여도 산소전달 효율을 유지할 수 있고 또한 물의 튀김을 방지할 수 있도록 한 하수 및 폐수처리 장치의 수면 임펠러에 관한것이다.The present invention relates to an impeller for surface aeration of sewage and wastewater treatment devices. In particular, it minimizes the impact of reflected waves on the surface of the water and maintains the oxygen transfer efficiency even when the water level is changed within a certain level range, and also prevents water splashing. It relates to a surface impeller of sewage and wastewater treatment equipment.
통상적으로 표면포기기용 임펠러는 수면에 설치되어 수면상부로부터 산소를 주입시키어 폐수에 산소를 접촉케하여 미생물을 호기성하에서 활성화 시킴으로써 하수 및 폐수중의 유기물을 제거하는데 사용된다.Typically, the surface aerator impeller is used to remove organic matter from sewage and wastewater by installing oxygen on the surface of water and injecting oxygen from the upper surface to bring oxygen into contact with wastewater to activate microorganisms under aerobic conditions.
제1도는 종래의 임펠러 구조를 보인 정면도로서, 허브둘레에 4∼6개의 직사각형 형상의 블레이드가 45°경사지게 고정된 구조로 되어있다.FIG. 1 is a front view showing a conventional impeller structure, in which four to six rectangular blades are inclined at an angle of 45 ° around the hub.
이러한 종래의 임펠러는 수며에서 구동시 물의 저항이 크고 반사파동의 충격으로 물이 수면위로 많이 튀게 되므로써, 감속기에 부하가 불균등하게 걸리고, 임펠러에 진동이 발생되며, 또한, 물이 튀길때 폐수속의 이물질등이 함께 튀기어 임펠러를 구동시키는 구동축 및 구조물에 달라 붙게 되므로서 수시로 청소를 하여야 하는 번거로움이 있고 특히 동절기에는 튀기는 물이 구동축이나 구조물에 얼어붙어 구동효율을 더욱 저해하고 있는 실정이었다.Such a conventional impeller has a high resistance of water when driven in water and a large amount of water splashes on the surface due to the impact of reflected waves, so that the load is unevenly applied to the reducer, the impeller is vibrated, and when the water splashes, foreign matters in the waste water flow, etc. The splashing is stuck to the drive shaft and the structure that drives the impeller, so there is a hassle to clean frequently. Especially in the winter, the splashing water freezes on the drive shaft or the structure, further impairing the driving efficiency.
또다른 문제점은 블레이드가 직사각형 형상을 이루고 있으므로서 수위가 떨어지게 되면 수면에 접촉되는 블레이드의 폭이 비례적으로 적어져 산소전달 효율이 급격히 떨어져 수위의 변화범위가 극히 적은 범위내에서만 목적하는 산소전달 효율을 유지할 수 있는 문제점이 있었다.Another problem is that since the blades have a rectangular shape, when the water level drops, the width of the blade contacting the water decreases proportionally, and the oxygen transfer efficiency drops sharply, so that the desired oxygen transfer efficiency is only within a range where the level of change of the water level is extremely small. There was a problem to maintain.
상기한 종래의 문제점을 해결하기 위하여 안출된 본 고안은, 각 블레이드가 곡면형상을 이루게 하면서 전체적으로 사다리 형상을 이루게 하여 수면반사 파동에 의한 충격의 최소화 및 수위의 변화 범위가 커도 일정범위내에서는 산소전달효율이 급격히 변하지 않도록 하는데 그 목적이 있다.The present invention devised in order to solve the above problems, each blade forms a curved shape while forming a curved shape as a whole to minimize the impact caused by the surface reflection wave and the oxygen transfer within a certain range even if the change range of the water level is large. The purpose is to prevent the efficiency from changing drastically.
또, 블레이드 상부에 튀김물 방지판을 구비하여 감속기 및 구조물에 튀어오르는 물을 차단하는데 또다른 목적이 있다.In addition, there is another purpose to block the water splashing on the reducer and the structure by providing a splash water prevention plate on the blade.
이하 첨부된 실시예의 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying embodiments as follows.
구동축(5)에 끼워지는 축관(1)의 둘레에 방사상으로 다수의 블레이드(2)(2')가 고정되고, 블레이드상에는 허브(6)에 연결이 가능하게 하면서 튀어오르는 물을 차단하도록 튀김방지판(4)이 구비된다.A plurality of blades 2, 2 'are radially fixed around the shaft tube 1 fitted to the drive shaft 5, and on the blades, it is possible to connect to the hub 6 to prevent splashing to prevent splashing water. The plate 4 is provided.
상기 블레이드(2)(2')는 수면의 반사파동에 의한 충격을 최소화 할수 있도록 평면상으로 곡면형상을 갖도록 형성되고 하단에는 수위의 변화범위 크기를 높이기 위하여 경사지게 형성시키어 전체적으로 사다리 형상을 이루게 되며, 각 블레이드(2)(2')의 측단부에는 산소전달 효율을 조절할 수 있도록 블레이드팁(3)이 착탈 가능하도록 구비된다.The blades (2) (2 ') is formed to have a curved shape in the plane to minimize the impact of the reflected wave of the water surface and at the bottom is formed to be inclined to increase the size of the change range of the water level to form a ladder shape as a whole, Side ends of the respective blades 2 and 2 'are provided with a detachable blade tip 3 so as to adjust the oxygen transfer efficiency.
미설명 부호 7은 보강대이다.Reference numeral 7 is a reinforcement bar.
이와같이 구성된 본 고안은 수면에 설치되어 구동시키게 되면 임펠러의 각 블레이드(2)(2')가 회전하면서 물살을 일으킬때 공기중의 산소가 주입되어 하수 및 폐수에 산소가 접촉되므로서 하수 및 폐수중의 유기물을 제거하게 되며, 각 블레이드(2)(2')가 곡면형상을 이루고 있어 수면을 젖히는 과정에서 각 블레이드(2)(2')의 곡면을 따라 물의 미끄러지므로서 수면의 반사파동에 의한 충격을 극소화 할 수 있는 동시에 물이 위로 튀는것을 최소화 할 수 있게 된다.The present invention configured as described above is installed in the water surface and driven, when each blade (2) (2 ') of the impeller rotates to cause water current, oxygen in the air is injected, and oxygen is brought into contact with the sewage and wastewater, which leads to sewage and wastewater. The organic matters of the blades are removed, and each blade 2, 2 'is curved, and the water slides along the curved surface of each blade 2, 2' in the process of raising the water surface. The impact can be minimized while water splashing up is minimized.
그리고 축관(1)에 고정된 블레이드(2)(2')의 전체형상이 사다리꼴 형상을 이루고 있으므로 인해 블레이드(2)(2')의 높이가 극대화 되어 수위가 일정 범위내에서 변하여도 산소전달 효율이 급격하게 변하지 않게 되고, 각 블레이드(2)(2')의 측단부에는 착탈이 가능한 블레이드 팁(3)이 구비되어 산소전달 효율을 조절 가능하게 한다.Since the overall shape of the blades 2 and 2 'fixed to the shaft 1 is trapezoidal, the height of the blades 2 and 2' is maximized, so that the oxygen transfer efficiency is achieved even if the water level is changed within a certain range. This sharp change does not change, and a detachable blade tip 3 is provided at the side ends of each blade 2 and 2 'to enable the oxygen transfer efficiency to be adjusted.
또 상기 블레이드(2)(2')상에는 튀김방지판(4)에 의해 각 블레이드(2)(2')가 회전시 튀기는 물을 차단하게 되어 구동축 및 구조물에 물이 튀는 것을 방지하며 특히 동절기에 구동축 및 구조물이 동결되는 것을 방지할 수 있게 된다.In addition, the blades (2) (2 ') on the blades (2) (2') to prevent the water splashing when the blade (2) (2 ') is rotated when rotating to prevent the water from splashing on the drive shaft and structure, especially in winter It is possible to prevent the drive shaft and the structure from freezing.
이상과 같이 본 고안은 효율을 증대시키는 임페럴를 제공할 수 있으며, 또한 물의 튀김을 방지할 수 있도록 한 임페러를 제공할수 있는 것이다.As described above, the present invention can provide an impeller to increase efficiency, and can also provide an impeller to prevent frying of water.
