본 고안은 하수 처리용 포기기의 임펠라 구조에 관한 것으로서 톱날 형상의 돌출부가 다수 형성된 본체 주위에 일정한 각도의 경사면과 절곡면을 구비하고 있는 다수의 블레이드를 수직으로 취부함으로써 임펠라 구동시 마찰 손실을 줄여 감속기와 베어링에 작용하는 축 방향의 추력을 크게 감소시켜 기기의 수명을 오래가게 함과 동시에 기포 발생을 크게 하여 산소전달 효율이 향상될 수 있도록 한 것이다.The present invention relates to the impeller structure of the aeration machine for sewage treatment, and reduces the frictional loss during the impeller driving by vertically mounting a plurality of blades having an inclined surface and a bent surface at a predetermined angle around a main body having a plurality of saw blade-shaped protrusions. The axial thrust acting on the reducer and the bearing is greatly reduced to prolong the life of the device and increase the bubble generation to improve the oxygen transfer efficiency.

각종 생활 하수와 오수 또는 축 수산 폐수나 산업 폐수 처리시설에 설치되어 생활 하수등의 생물학적 산소 요구량(BOD)을 적정 수준으로 유지시키기 위한 장치로서 생활 하수속에 기포를 발생시켜 기포내의 산소가 용해되어 산소 함유량이 증가되도록 하는 포기기(泡起機)가 설치 운용되고 있다.It is installed in various household sewage and sewage or livestock fishery wastewater or industrial wastewater treatment facilities to maintain the biological oxygen demand (BOD) of living sewage at an appropriate level.It generates bubbles in the daily sewage and dissolves oxygen in bubbles. The aeration machine which makes content increase is installed and operated.

본 고안은 이와 같은 포기기에 있어서 포기기의 구동축에 장착되어 기포를 발생시키는 임펠라의 구조에 관한 것으로 종래의 포기기 임펠라는 단순히 수개의 회전날개가 장착된 구조로 되어 있었기 때문에 큰 물보라만을 발생시켜 생성된 기포가 수면위로 비상하여 하수내에 산소를 효율적으로 전달시키지 못하는 결함과 함께 마찰저항이 크게 발생하여 기기의 수명이 단축되고 가동비가 상승하게 되는 폐단이 있었다.The present invention relates to a structure of an impeller mounted on the drive shaft of the aeration machine to generate air bubbles in the aeration device. Since a conventional aeration impeller simply has a structure in which several rotary blades are mounted, it generates a large spray. In addition to the defects that caused the air bubbles to rise above the surface of the water efficiently, the frictional resistance was greatly generated, resulting in shortened equipment life and increased operating costs.

본 고안은 이와 같은 종래의 포기기 임펠라가 안고 있는 문제점을 감안하여 고안된 것으로서 본 고안은 톱날 형상의 돌출부가 다수 형성된 본체 주위에 일정한 각도의 경사면과 절곡면을 구비하고 있는 다수의 블레이드를 수직으로 취부함으로써 임펠라 구동시 마찰손실을 줄여 감속기와 베어링에 작용하는 축 방향의 추진력을 크게 감소시켜 기기의 수명을 오래 가게 함과 동시에 기포 발생을 크게 하여 산소 전달 효율이 향상될 수 있도록 한 것이다.The present invention was devised in view of the above problems of the conventional aeration impeller, and the present invention is a vertical mounting of a plurality of blades having an inclined surface and a bent surface at a predetermined angle around a main body formed with a plurality of saw blade-shaped protrusions. By reducing the friction loss during the driving of the impeller, the axial thrust acting on the reducer and the bearing is greatly reduced, thereby extending the life of the device and increasing the bubble generation, thereby improving the oxygen transfer efficiency.

이하 본 고안을 첨부 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안의 외형 사시도 제2도 및 3도는 본 고안의 평면도 및 정면도로서 톱날 형상의 두개의 돌출면(1)(1')으로 이루어진 돌출부(2)가 다수 형성된 본체(3)의 중심부에 임펠라축 취부용 볼트공(3')이 다수 형성되고 상기 돌출면(1')에 접촉되어 30-40도 가량 기울어진 경사면(4)과 절곡면(4')을 갖는 블레이드(5)가 본체(3)와 수직으로 입설되어 있다.1 is an external perspective view of the present invention 2 and 3 are a plan view and a front view of the present invention, the center of the main body 3 is formed with a plurality of projections (2) consisting of two protruding surfaces (1) (1 ') of the saw blade shape A plurality of impeller shaft mounting bolt holes 3 'are formed in contact with the protruding surface 1' and a blade 5 having an inclined surface 4 and a bent surface 4 'inclined about 30-40 degrees. It is placed perpendicular to the main body 3.

제4도는 본 고안의 작동 상태를 나타낸 부분 종단면도로서 모터(6)가 구동하여 모터(6)에 열결된 감속기(7)가 감속 회전하면 감속기축(8)에 연결된 임펠라축(9)이 구동되고 그에 연결된 임펠라(10)가 구동하게 된다. 임펠라(10)가 회전하면 임펠라(10)에 장착된 블레이드(5)의 상측단부에 형성된 절곡면(4')에 의해 하수 처리조(11)내의 하수가 부딪쳐 와류를 일으키며 기포를 발생시키게 된다. 이때 발생된 기포는 기포내의 산소를 하수에 용해시켜 하수가 적정량의 산소를 포함할 수 있도록 한다.4 is a partial longitudinal cross-sectional view showing the operating state of the present invention, when the motor 6 is driven and the reducer 7 connected to the motor 6 decelerates and rotates, the impeller shaft 9 connected to the reducer shaft 8 is driven. And the impeller 10 connected thereto is driven. When the impeller 10 rotates, the sewage in the sewage treatment tank 11 is swept by the bent surface 4 'formed at the upper end of the blade 5 mounted on the impeller 10 to generate vortices and generate air bubbles. Bubbles generated at this time dissolve the oxygen in the bubble in the sewage so that the sewage may contain an appropriate amount of oxygen.

따라서 이와 같은 본 고안의 하수 처리용 포기기의 임펠라 구조에 의하면 톱날 형상으로 이루어진 돌출부(2)의 돌출면(1')과 접촉되어 블레이드(5)가 수직으로 입설된 상태에서 경사면(4)이 상측으로 약 30-40도 가량 기울어져 있기 때문에 하수와의 접촉시 마찰손실을 줄여 감속기와 베어링에 작용하는 축방향의 추력을 감소시킬 수 있는 잇점이 있을 뿐만 아니라 발생된 기포가 수면으로 비상함이 없이 수중으로 유입되도록 유도함으로써 하수내의 산소 전달 효율을 증대시킬 수 있는 효과가 있다.Therefore, according to the impeller structure of the aeration device for sewage treatment according to the present invention, the inclined surface 4 is in contact with the protruding surface 1 ′ of the protruding portion 2 having a saw blade shape and the blade 5 is vertically placed. Since it is inclined upward by about 30-40 degrees, it has the advantage of reducing the frictional loss in contact with the sewage and reducing the axial thrust acting on the reducer and the bearing. By inducing to be introduced into the water without the effect is to increase the oxygen transfer efficiency in the sewage.
