Description

수질정화용 수중기포 발생장치{.}Underwater Bubble Generator for Water Purification {.}

본 발명은 수중에 산소 기포가 공급되게 함으로서, 수중의 용존 산소량을 증대시키고 수질 정화를 하기 위한 것으로서, 특히 간단한 구조로서 산소 용존량을 극대화시키기 위한 수질 정화용 기포 발생 장치에 관한 것이다.The present invention is to increase the amount of dissolved oxygen in water and to purify the water by allowing oxygen bubbles to be supplied into the water, and more particularly, to a bubble generator for water purification for maximizing the amount of oxygen dissolved in a simple structure.

일반적으로 어패류 양식장이나 폐수처리장 또는 호수 등에 설치하여 수중에 산소를 공급하여 용존 산소량을 증대시키기 위한 장치가 널리 개발되어 왔다.In general, a device for increasing the amount of dissolved oxygen by supplying oxygen in water by installing in aquaculture fish farms, wastewater treatment plants or lakes has been widely developed.

이러한 종래의 장치로서 수차나 블로워에 의한 방법이 있으며, 수차에 의한 방법은 설비가 거대하고 산소 공급이 대기와 접촉에 의하여 이루어 지므로 효율이 떨어져 널리 이용되지 못하고 있다.As such a conventional apparatus, there is a method by aberration or blower, and the method by aberration is not widely used due to its poor efficiency because the equipment is huge and the oxygen supply is made by contact with the atmosphere.

근래에는 블로워 방식이 이용되고 있으며, 이는 모타에 의하여 회동되는 날개에 외부에서 강제 공급되는 공기가 접촉되면서 기포가 발생되도록 구성된 것이 다.In recent years, a blower system has been used, which is configured to generate bubbles as the air forcedly supplied from the outside comes into contact with the blade rotated by the motor.

그러나, 이러한 장치는 별개의 에어 펌프에서 공급되는 공기가 호오스를 통하여 날개의 근접된 위치에 도달되어야 되므로 전체 장치가 복잡해지고 설치 비용이 많이 소모되었다.However, such a device requires the air supplied from a separate air pump to reach the wing's proximal position through the hose, which complicates the entire device and consumes a lot of installation costs.

즉, 산소를 공급하여야 되는 양식장이나 폐수처리장 및 호수 등은 비교적 넓은 면적이며, 이러한 곳에 상기 장치가 다수개 설치되어야 하므로 각각의 장치를 상기 호오스로 연결하는데 따른 작업의 복잡성이 있었다.That is, a farm, a wastewater treatment plant, and a lake to supply oxygen have a relatively large area, and since a plurality of the devices must be installed in such a place, there is a complexity of connecting each device to the hose.

본 발명은 상기한 문제를 해결하기 위하여 연구 개발된 것으로서, 내부 중앙에서 외측으로 공기가 통과되도록 하여 기포의 발생이 미세화 되어 산소의 용해가 원활하게 이루어지도록 하는 데 그 기술적 과제가 있다.The present invention has been researched and developed in order to solve the above problems, there is a technical problem to allow the air to pass from the inner center to the outside so that the generation of bubbles is fine to smoothly dissolve oxygen.

본 발명의 다른 기술적 과제는 별도의 에어공급배관이 없이 수중모타에 직접 공기유입호스가 연결되어 수중모터의 중공축(구멍이 뚫려있는 축)을 통하여 공기가 공급되는 간단한 구조로서 설치 작업을 손쉽게 할 수 있는 데 있다.Another technical problem of the present invention is that the air inlet hose is directly connected to the underwater motor without a separate air supply pipe, so that the air is supplied through the hollow shaft of the underwater motor. It's there to be.

본 발명은 수중에 공기를 공급하여 미세기포가 발생되도록 하기 위하여, 모타의 회동축 내부에 공기유입통로를 형성하며 원판형의 회전판 내부에 확산로를 형성하고 회전판의 외곽부에 다수 개의 날개를 부착하여 구성한 것이다.The present invention forms an air inflow passage in the rotational shaft of the motor in order to supply air into the water to form a micro-bubble, to form a diffusion path in the disk-shaped rotating plate and to attach a plurality of wings to the outer portion of the rotating plate It is configured by.

이하, 본 발명의 구성 및 이에 따른 작용을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the configuration and operation of the present invention in detail as follows.

도 1은 본 발명의 사용 상태를 보인 사시도이며, 도 2는 본 발명의 일부를 절결한 측면도이다.1 is a perspective view showing a state of use of the present invention, Figure 2 is a side view of a part of the present invention cut out.

본 발명은 도 1과 도 2에 도시된 바와 같이, 수중 모타(1)의 중앙에 회동되도록 장치된 회동축(2) 내부에 공기유입통로(3)가 구비되도록 형성한다.As shown in FIG. 1 and FIG. 2, the air inlet passage 3 is provided inside the rotation shaft 2 provided to rotate in the center of the underwater motor 1.

그리고 하방으로 향할수록 넓어지는 원추형 샤프트(5) 하방에 원판형의 회전판(6)을 고정하여 원추형 샤프트(5)의 내부에 공기 분산실(5a)이 구비되고 회전판 (6)의 내부에 확산실(7)이 구비되도록 형성하며 상기 회동축(2)의 하방에 원추형 샤프트(5)의 상단부를 일체로 연결한다.In addition, an air dispersion chamber 5a is provided inside the conical shaft 5 so that the disk-shaped rotating plate 6 is fixed below the conical shaft 5 which is widened toward the lower side, and the diffusion chamber is provided inside the rotating plate 6. (7) is formed to be provided to connect the upper end of the conical shaft (5) integrally below the rotation shaft (2).

그리고 상기 회전판(6)의 외곽부에 다수 개의 날개(8)를 일정간격으로 고정 설치하며, 날개(8)는 회전판(6)의 외곽부로 돌출된 측단부(8a)와 상하로 돌출된 상하단부와(8b)와 회전판(6)의 내측에 위치된 내측부(8c)로 구획형성한다.And fixed to a plurality of wings 8 to the outer portion of the rotary plate 6 at regular intervals, the wing 8 is a side end portion 8a protruding to the outer portion of the rotary plate 6 and the upper and lower ends protruding up and down It is partitioned into the vortex 8b and the inner part 8c located inside the rotating plate 6.

미설명부호 9는 지지대이며, 10은 대기중의 공기가 유입되는 에어호오스이다 11은 수중 모타(1)에 전원을 공급하기 위한 전선이다.Reference numeral 9 denotes a support, 10 denotes an air hose through which air in the air flows, and 11 denotes an electric wire for supplying power to the motor 1 in the water.

본 발명은 양식장, 폐수처리장, 호수 등에 설치하여 사용하는 것으로서 도 1에 도시된 바와 같이 지지대(9)에 의하여 수중 모타(1)의 하방이 안정된 상태로 지지되로록 설치한 후, 에어호오스(10)의 상단부가 수면 위로 돌출되게 설치한다.The present invention is installed in a farm, a wastewater treatment plant, a lake, and the like, as shown in FIG. 1, and installed in such a manner that the lower side of the underwater motor 1 is supported in a stable state by a support 9, and then an air hose ( Install the upper end of 10) to protrude above the surface of the water.

이러한 방법으로 다수 개를 설치한 후, 전선(10)을 통하여 수중 모타(1)에 전원이 공급되면, 회동축(2)이 일방향으로 회동되며, 회동축(2)에 일체로 고정된 원추형 샤프트(5)와 회전판(6) 및 날개(8)가 일체로 회동된다.After installing a plurality of in this way, when the power supply to the underwater motor (1) through the electric wire (10), the rotating shaft (2) is rotated in one direction, the conical shaft fixed integrally to the rotating shaft (2) 5, the rotating plate 6, and the blade 8 are rotated integrally.

날개(8)가 회동되면서 날개(8) 부위에 회전 압력이 발생되고 이러한 회전 압력에 의하여 확산실(5a)에 복압(진공압)이 발생하여 따라 외부의 공기가 공기유입통로(3)를 통하여 공기 분산실(5a)에서 하방으로 향한 후 확산실(7)에서 외측으로 유출되며, 이때 기포가 발생되는 것이다.As the blade 8 is rotated, a rotational pressure is generated at a portion of the blade 8, and a double pressure (vacuum pressure) is generated in the diffusion chamber 5a by the rotational pressure, so that outside air passes through the air inflow passage 3. After going downward in the air dispersion chamber 5a, it flows outward from the diffusion chamber 7, and bubbles are generated at this time.

즉, 회동되는 날개(8)의 측단부(8a)와 내측부(c)에 저항이 발생되어 미세한 기포가 다량 발생되는 것이다.That is, resistance is generated in the side end portion 8a and the inner side portion c of the blade 8 that is rotated, so that a large amount of fine bubbles are generated.

상기에서 수중에 공급된 미세 기포는 물에 용해되여 산소용존량을 증대시킴으로 수질개선 및 정화 기능이 수행되는 것이다.The fine bubbles supplied in the water is dissolved in water to increase the dissolved oxygen, water quality improvement and purification is performed.

본 발명은 내부 중앙으로 공급되는 공기가 외측으로 확산되면서 날개의 근접된 위치에 공급되므로 기포를 미세화시켜 산소용존량을 증대시킬 수 있는 효과가 있다.The present invention has the effect of increasing the oxygen dissolved amount by miniaturizing the air bubbles because the air supplied to the inner center is supplied to the adjacent position of the wing while spreading outward.

또한, 회동축 내부를 통하여 대기 중의 공기가 유입되므로 별개의 공기 공급배관 설비가 에어 호오스 없이 간단한 구조로 설치할 수 있는 것이다.In addition, since the air in the air flows through the inside of the rotating shaft, a separate air supply piping facility can be installed in a simple structure without an air hose.

본 발명은 양식장이나 폐수처리장 및 호수 등 산소용존량을 증대시킬 필요가있는 모든 곳에 쉽게 설치하여 수질개선 및 정화할 수 있는 유익한 발명인 것이다.The present invention is an advantageous invention that can be easily installed in all places that need to increase the oxygen dissolved amount, such as aquaculture farms, wastewater treatment plants and lakes.
