[Prior Art] Conventionally, as a method of supplying oxygen to water in aquariums, ponds, etc., there are underwater aeration methods in which air bubbles are generated in water using a compressor or blower, and a method in which aeration is carried out using the injector effect of pump water pressure. There is. In these bubble generation methods, underwater piping and aeration pipes are placed underwater.

In addition, since air is ejected into the water from the nozzle hole, the particle size of the generated air bubbles becomes large, reducing the gas-liquid contact area and contact time, so a large aeration effect (oxygen dissolution efficiency) is expected. The problem was that I couldn't do it.

[Function] The present invention is configured as described above, and includes a submersible pump that is rotatably driven by a motor and equipped with an impeller that pumps water drawn from the water intake port toward the water outlet, and an intake pipe. , One end of the intake pipe protrudes above the water surface, and the other end of the intake pipe is connected to the water intake port of the submersible pump 8. It is small,
There is no need to install submersible piping or air diffuser pipes, making installation work and maintenance easy. Furthermore, since water and air are mixed and stirred by the impeller, the particle size of air bubbles is reduced and the air-liquid contact area is reduced. As the value increases, the contact time becomes longer and a greater aeration effect can be obtained.

[Embodiment] FIG. 1 shows an embodiment of the present invention, in which a submersible pump 1 is provided with an impeller 5 that is rotationally driven by a motor 2 and pumps water sucked in from a water intake port 3 toward a water outlet 4.
and an intake vibro, with one end protruding above the water surface and the other end facing the water intake port 3 of the submersible pump 1. In the embodiment, an air adjustment valve is installed at one end of the intake vibro. There are 8. Further, the impeller 5 attached to the rotating shaft 2a of the motor 2 is provided with a large number of pores 5a. Note that the size of the water inlet 3 is set smaller than the size of the water outlet 4, so that the foreign matter sucked in can be smoothly discharged.

Here, since one end of the suction vibro has one end protruding above the water surface and the other end faces the water intake port 3 of the submersible pump 1 (via the pipe section 7a of the main body case 7), water is sucked in at the same time. Air is also sucked in and mixed and stirred by the rotation of the impeller 5, causing turbulence and cavitation to reduce the particle size of the bubbles. Therefore, as the gas-liquid contact area becomes larger and the contact time becomes longer, a large aeration effect can be obtained, and the water outlet 4 of the submersible pump l
Cloudy water containing microscopic air bubbles will be spewed out. Furthermore, if a large number of pores 5a are provided in the impeller 5, larger ultrasonic waves are generated due to the cavitation phenomenon, promoting mixing and agitation of water and air (making them more fine particles), and further improving the aeration effect (conventional example). This results in an oxygen dissolution rate several times higher than that of the oxygen dissolution rate.

Furthermore, if too much air is introduced into the submersible pump 1, the pump function will be reduced (the lift amount will be reduced), so it is necessary to adjust the amount of air sucked in by the air adjustment valve 8 to an appropriate amount.
