본 고안은 하수 처리용 수중 포기기에 관한 것이다.The present invention relates to an underwater aeration machine for sewage treatment.
최근 각종 생활 하수나 오수 또는 축 수산 폐수나 산업 폐수로 인한 환경 오염이 심각한 사회 문제로 대두됨에 따라 하천등으로 배출하는 생활 하수등을 환경기준에 적합한 수준으로 정화 처리 할 것을 의무화하고 있다.Recently, as environmental pollution caused by various kinds of domestic sewage, sewage, livestock and fisheries wastewater, and industrial wastewater has become a serious social problem, it is mandatory to purify the household sewage discharged to rivers according to environmental standards.
이에 따라 하수 종말 처리장이나 폐수처리 시설등에는 생활 하수등의 생물학적 산소 요구량(BOD)을 적정수준 이상으로 유지시키기 위하여 기계적인 장치로 기포를 발생시켜 공기중에 포함되어 있는 산소가 생활 하수등에 용해되어 산소 함유량을 증가시키도록 하는 수중 포기기(水中 泡起機)가 설치되어 있다.Accordingly, in order to maintain the biological oxygen demand (BOD) such as domestic sewage in the sewage terminal treatment plant or waste water treatment facility above the proper level, bubbles are generated by a mechanical device, and oxygen contained in the air is dissolved in the domestic sewage and the like. An underwater aeration machine is provided to increase the content.
그러나 지금까지 사용되고 있는 수중 포기기는 그 구조가 복잡하여 소음이 많이 발생하고 고장이 자주 발생하는 폐단과 함께 기포 발생시 큰 물보라가 발생하여 산소전달 효율이 감소되고 설치 면적이 많이 요구됨과 동시에 많은 부하가 걸림에 따라 가동비용이 증가하게 되는 등의 결점이 있었다.However, the underwater aeration machine used up to now has a complicated structure, which generates a lot of noise and breakdowns frequently, and a large splash occurs when bubbles are generated, which reduces oxygen transfer efficiency, requires a lot of installation area, and takes a lot of load. As a result, the operating cost increases.
본 고안은 이와 같은 종래의 수중 포기기가 갖고 있는 제반 문제점을 감안하여 연구된 것으로서 본 고안의 목적은 구조가 간단하여 소음이 적고 설치및 유지 관리와 보수가 용이하며 산소전달 효율이 극히 뛰어난 수중 포기기를 제공하는데 있다.The present invention has been studied in view of all the problems of the conventional abandoner, and the purpose of the present invention is to provide a simple audible underwater abandoner with low noise, easy installation, maintenance and repair, and excellent oxygen transfer efficiency. To provide.
이와 같은 본 고안은 하수 침투시 센서의 작동으로 모터의 구동을 멈춰 모터실로 하수가 유입되는 것이 방지되도록 한 기름실과 상기 기름실의 하측과 수중에 장착된 공기 흡입관의 단부 사이의 지지판상에 설치되어 임펠라의 회전으로 공기가 하수와 혼합되어 와류를 일으키며 기포를 발생시키는 기포 생성실과 상기 지지판상에 톱날상으로 배열되어 상기 기포 생성실에서 생성된 기포와 하수가 혼합되어 포기조내로 토출 순환되도록 한 요구가 형성된 가이드판과 그에 연결된 토출관으로 이루어진 것을 특징으로 한다.The present invention is installed on the support plate between the oil chamber and the lower end of the oil chamber and the end of the air suction pipe mounted in the water to stop the driving of the motor by the operation of the sensor when the sewage infiltration is prevented from entering the motor chamber There is a demand that the air is mixed with the sewage by the rotation of the impeller so as to vortex to form bubbles and arranged in the shape of saw blades on the support plate so that the bubbles and sewage generated in the bubble generating chamber are mixed and discharged into the aeration tank. Characterized in that the guide plate formed and the discharge pipe connected thereto.
이하 본 고안을 첨부 도면을 참조하며 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안의 외형 사시도로서 본체(1) 상부에 전원코드(2)가 밀봉되어 연결되어 있고 하측에 기포 생성부(3)가 장착되어 있으며 이 기포 생성부(3)는 공기 흡입관(4)(4 )과 연결되어 단부에 탄성편(5 )이 부착된 지지간(5)에 의하여 포기조(16)내에 지지 설치되어 있다.1 is an external perspective view of the present invention, the power cord 2 is sealed and connected to the upper part of the main body 1, and the bubble generating unit 3 is mounted on the lower side thereof, and the bubble generating unit 3 is an air suction pipe 4. (4) is supported in the aeration tank (16) by a supporting section (5) connected to the end (4) and having an elastic piece (5) attached to the end.
제2도는 본 고안에 부착된 임펠라(6)의 발췌 사시도로서 축봉(7)의 하측으로 톱날형상의 두개의 돌출면(8 )(8 )으로 이루어진 돌출부(8)가 수개 돌출된 형상으로 되어 있다.2 is an excerpt perspective view of the impeller 6 attached to the present invention, in which a protrusion 8 consisting of two saw blades 8 and 8 having a saw blade shape protrudes below the shaft 7. .
제3도는 본 고안에 장착된 기포 생성부(3)의 분리 사시도로서 공기 흡입관(4)(4 )이 지지판(9)의 중앙에 형성된 통공(10)과 연통되어 있고 이 통공(10)의 상측 주위에는 요구(11)가 톱날형상으로 배열된 가이드판(11 )과 토출관(12)이 다수 장착되어 있다.3 is an exploded perspective view of the bubble generating unit 3 mounted in the present invention, in which the air suction pipes 4 and 4 communicate with the through holes 10 formed in the center of the support plate 9, and the upper side of the through holes 10 is shown. The guide plate 11 and the discharge pipe 12 in which the request | requirement 11 was arranged in saw blade shape are attached to the periphery.
제4도는 본 고안의 작동 상태를 나타낸 부분 종단면도로서 본 고안의 하수 처리용 수중 포기기는 본체(1)내에 장착된 수중모터(13)가 회전하여 모터축(14)과 연결된 축봉(7)과 임펠라(6)가 회전하면 공기흡입관(4)의 상측에 연결된 흡입관(4 )을 통하여 흡입된 공기가 기포 생성부(3)의 통공(10)을 통하여 지지판(9)의 중앙에 형성된 기포 생성실(15)로 유입된 뒤 회전하는 임펠라(6)에 의하여 포기조(16)내의 하수와 혼합되면서 와류를 일으켜 미세한 기포를 발생 시키게 된다. 발생된 기포는 하수와 함께 기포내의 산소를 하수속에 용해시키면서 가이드판(11 )에 형성된 요구(11)에 의하여 토출관(12)으로 유도되어 포기조(16)로 다시 배출 순환되며 연속적으로 공기중의 산소를 하수속으로 용해시켜 생물학적 산소요구량을 기준치 이상으로 높여주게 된다.4 is a partial longitudinal cross-sectional view showing an operating state of the present invention, the aeration device for sewage treatment according to the present invention includes a shaft 7 connected to the motor shaft 14 by rotating an underwater motor 13 mounted in the main body 1; When the impeller 6 rotates, the air generated through the suction pipe 4 connected to the upper side of the air suction pipe 4 is formed in the center of the support plate 9 through the through hole 10 of the bubble generating unit 3. (15) is mixed with the sewage in the aeration tank (16) by the impeller (6) rotated after the introduction of the vortex to generate a fine bubble. The generated bubbles are led to the discharge tube 12 by the request 11 formed on the guide plate 11 while dissolving oxygen in the bubbles together with the sewage in the sewage and discharged back to the aeration tank 16 and continuously It dissolves oxygen into the sewage, raising the biological oxygen demand above the standard.
한편 하수가 모터(13)로 침투되는 것을 방지하기 위하여 모터실(17)과 기포 생성실(15)의 사이에 센서(18)가 부착된 기름실(19)이 설치되어 하수가 모터실(17)로 침투하기전에 기름실(19)에 1차 침투되면 센서(18)가 작동하여 모터(13)의 작동을 정지시켜 고장이나 안전사고 등이 발생하는 것을 사전에 예방하게끔 되어 있다.Meanwhile, in order to prevent the sewage from penetrating into the motor 13, an oil chamber 19 having a sensor 18 is installed between the motor chamber 17 and the bubble generating chamber 15 so that the sewage can be removed from the motor chamber 17. When the first penetration into the oil chamber 19 before the penetration into the ()), the sensor 18 is operated to stop the operation of the motor 13 to prevent failure or safety accidents in advance.
따라서 이와 같은 본 고안의 하수 처리용 수중 포기기에 의하면 보다 간단하고 효율적인 구조로서 대기중의 공기를 미세한 기포로 변화시켜 산소를 하수내에 기준치 이상으로 충분히 용해시킬수 있는 효과가 있을 뿐만 아니라 수중에 설치된 공기흡입관(4 )의 단부와 돌출관(12)의 사이에 기포생성실(15)이 설치되어 있으므로 기포 발생시 물보라가 수면위에 부상하지 아니하여 산소전달 효율을 크게 증대시킬 수 있는 등의 잇점이 있다.Therefore, according to the water aeration device for sewage treatment according to the present invention, the air intake pipe installed in the water as well as the effect of changing the air in the air into fine bubbles and dissolving oxygen in the sewage above the standard value is simpler and more efficient. Since the bubble generation chamber 15 is provided between the end of the (4) and the protruding pipe 12, there is an advantage that the spraying does not float on the water surface when the bubble is generated, which can greatly increase the oxygen transfer efficiency.
