た。Further, the applicant of the present invention has filed a "blade surface ejection type" aeration device technology / patent application 62 as a new method of air ejection different from the screw type aeration device for ejecting air from the conventional rotary shaft end. -016634, 62-1
11366 and 2-254693. As a new air ejection method, there is a technology / patent application No. Hei 2-417929 of the "partition structure utilizing method", but a prototype machine was commercialized for commercialization by the applicant and the company owned by the same applicant. When we manufactured and measured the performance, we compared the amount of air sent when sucking air by unifying the motor output with "Hitachi Kiden's spiral screw type aerator" which has the highest performance at this stage, the former blade Surface ejection is 4 compared to conventional
A performance of about 4% was recorded, and it was found that the latter type using a partition structure improved performance by about 20% compared with the conventional type.
However, the inventors of the present invention prototyped a patent application No. Hei 2-254693, which was prototyped on the basis of a different principle, and measured the performance. --- It has the characteristic that the thick rotary shaft has a pre-throttled structure, and the holes are formed at two locations where the pressure distribution is different to increase, and the tip shaft core portion of the rotary shaft, which is the same location as in the past, is used. At the same time as forming a hole, the "blade surface ejection method" and "partition structure utilization method" with different pressure distribution
It was intended to eject air in two stages by means of holes that were formed at locations such as the above, and holes that were formed at locations with different pressure distributions were used to measure air flow rate with this prototype. However, it resulted in no performance. Therefore, as a result of struggling with various causes, the hole formed at the tip of the rotating shaft was accidentally blocked as in the conventional case. In Japanese Patent Application No. Heisei 3-181918, "Aeration device excellent in air feeding capacity (large diameter Tube type) ”, which is almost three times the conventional 27
It was decided to measure a 1% explosive air ejection amount.
Therefore, as a result of an analysis based on this by the applicant, when a plurality of holes are formed at different pressure distribution states, when the rotation speed is gradually increased, the blade portion among the plurality of holes is formed. When the suction force begins to work on the hole portion that ejects air even at low speed rotation due to the rotation of the water, water is sucked by the pressure difference from the hole portion that can eject air at high speed rotation, and each of the holes We found out that a phenomenon of water circulation like a pump occurred between the parts.

The present invention is to generate a difference in the flow of liquid by the rotation of the blade portion 1, that is, to generate a pressure difference (decompression) in water,
This pressure difference is used as a suction force for ejecting air to act in a specific pipe to eject air. According to the present invention, a plurality of holes 6 are formed at different pressure distributions in the vicinity of the blade portion 1 such as a screw or a turbine blade, and air is ejected from both of them to eliminate the above-mentioned problems. It is a solution. In addition, in order to prevent water droplets from rising from the air passage 5 ', which has a weak pressure due to the rotation of the screw, a water drop back-up prevention valve is formed near the water surface above the air passage 5'in the atmosphere.

A partition 7 is formed so as to prevent the solution from flowing between the plurality of holes 6 formed at the locations where the pressure distribution is different, and the air passages 5 and 5'are separated from each other. Furthermore, when the air passages 5 coincide with each other inside the pipe body 4 from underwater, the suction force exerted on the one air passage 5 causes the other air passage 5 to move.
Even if the water level in the pipe of ｀ rises, a sufficient amount of partition 7 is extended above the water level, which is the suction force acting on one air passage 5 and the liquid filled in the other air passage 5 ″. It is characterized in that the partition 7 is formed longer than the upper limit point due to its own weight.

に曝気できる。Further, according to the second aspect, the plurality of air passages 5 and 5'for ejecting air from the holes 6 having different pressure distributions are completely independently formed to form the regions having different pressure differences. By connecting a plurality of different air passages 5 and 5'to the air ejection hole portion 6 respectively, the above-mentioned problem can be solved more completely. The plurality of air passages 5 and 5'attached to the rotary shaft 11 are in the middle. By adopting a structure that does not coincide with each other, the pressure difference of the one generating the suction force among the plurality of air passages 5 and 5'is not transmitted to the other air passage 5 '. As a result, the blade part 1 is rotated at a specific rotation.
The air ejection holes 6 and the air passages 5 and 5'formed in the areas where the pressure difference when moving is different from each other surely have different air ejection amounts due to the difference in the depressurizing force applied. Air can be ejected from the portion 6, and the pressure distribution area generated by the blade portion 1 can be fully utilized to aerate a larger amount of air.
