〔The invention's effect〕

In the invention of claim 1, an air intake port 7 is formed at the upper end and an air discharge port 8 is formed at the lower end of the output shaft 3a protruding from below the prime mover 3, and the air intake port 7 and the air discharge port 8 are formed.
A hollow rotary shaft B communicating with the rotary shaft B is connected to the rotary shaft B so as to be exposed to the outside from the lower end of the rotary shaft B, and an impeller 10 is fixed to a position lower than the discharge port 8. With the aeration processing apparatus provided with, firstly, the aeration processing work can be performed easily, secondly, the structure is simple and can be provided at a low price, and thirdly, maintenance and management can be performed. The effect is that it can be easily performed and the maintenance cost can be reduced.

To describe these effects in detail, the prime mover housing case A
Since the float part 18 is provided at the lower end of the engine, the aeration treatment apparatus of the present invention can be floated on the surface of a fluid such as manure of livestock used as fertilizer for the storage tank P, and the prime mover built in the prime mover housing case A. When the rotating shaft B is rotated by starting No. 3, the impeller 10 fixed to the lower end of the rotating shaft B stirs the manure, and the stirring point locally becomes a negative pressure.
The air flows in from the air intake port 7 above the air intake port, and the air is discharged from the air exhaust port 8 below the rotation axis B, and the air can be sent into the manure as the impeller 10 is stirred.

In particular, while projecting outward from the lower end of the rotating shaft B,
Since the impeller 10 is fixed to a position lower than the air discharge port 8, the stirring position by the impeller 10 is in the negative pressure state as described above, and the air discharge port 8 is present immediately above the impeller 10. Therefore, the air in the rotating shaft B is
The air is drawn to the 0 side, and an extremely large amount of air can be sent into the manure in the storage tank P.

Further, the air outlet 8 of the rotary shaft B has the advantage that the manure in the storage tank P can be stirred with air by rotating with the rotary shaft B, and the stirring efficiency can be increased together with the impeller 10.

This is an extremely simple operation, and unlike the conventional aeration processing apparatus having a large-scale structure, there is almost no construction cost and the cost can be reduced. In this way, by mixing air in the manure, the manure can be produced as an odorless livestock fertilizer by this oxidizing action.

Further, in maintenance and management, the aeration treatment apparatus of the present invention is taken out from the storage tank P, and the rotating shaft B and the impeller 1 which consume the most are consumed.
0 can be easily replaced, the worker can be extremely prevented from becoming dirty during the replacement work, and the maintenance cost can be reduced.

It can also be used as a device for feeding oxygen into water in a fish culture pond.

Next, in the invention of claim 2, below the prime mover 3,
A rotary shaft B having an air intake port 7 and an air exhaust port 8 and an impeller 10 fixed to the lower end of the rotary shaft B by being exposed to the outside.
And the air intake port 7 and the air exhaust port 8 rotate together with the rotating shaft B so that the external air can be exhausted to the 10 locations of the impeller, and these are provided on the fixed base C so as to be movable in the vertical direction. By using this aeration processing device, if this fixed mount C is installed in a fish culture pond, etc.
Oxygen can be sent into water to increase the amount of dissolved oxygen in the water, and it can be used for aquaculture.

Even if it is installed in only one place, unlike manure, it is not viscous in water, so oxygen can be sufficiently sent to the entire tank.

Moreover, it goes without saying that this device can also perform aeration treatment of excrement. Further, the prime mover 3, the rotating shaft B, the impeller 10 and the like are vertically movable on the fixed base C, and the rotating shaft B can be set in the storage tank P at a desired depth.

That is, since the prime mover housing case A is slidably fixed to the fixed base C in the vertical position, the impeller 10 fixed to the lower end of the rotating shaft B is set at a desired depth in the excrement of the storage tank P. it can. Further, when the prime mover housing case A and the rotating shaft B are slanted and moved in the vertical direction, the aeration process can be performed while circulating the excrement of the storage tank P, and the rapid aeration process can be realized. (See figure).

Further, the rotary shaft B has an air intake port 7 and an air exhaust port 8 and these rotate together with the rotary shaft B. Therefore, the air of the rotary shaft B contained in the excrement in the storage tank P is reduced. The outlet 8 has an advantage that it can stir the manure with the impeller 10.

Further, the impeller 10 that is exposed and fixed to the outside is provided at the lower end of the rotating shaft B, and the external air can be discharged to the 10 positions of the impeller. In the negative pressure state, the external air is easily directed to the 10 locations of the impeller, and the impeller 10 evenly distributes the external air to the surroundings.
