駆動軸内の中空孔によって導通されている。In the figure, 1 indicates the entire aeration device for stirring and aerating liquid, and this aeration device 1 has a drive motor 2 and a hollow drive shaft 3.
This drive motor 2 is connected directly or through a joint.
, the drive shaft 3 is covered with an aerator cover 4, and the draft chute is arranged so that the lower end of the cover 4 covers the lower part of the drive shaft 6 and the agitation blade 5 of a desired shape provided at the end of the shaft. A professional was installed to drill a slit 7 in the connecting part between the aerator cover and the draft chive, and install this device into a tank, pond, or other stirring tank at the required depth and angle of inclination. Insert and support. In addition, the hollow drive shaft 3 is provided with a suction hole 3a in the form of a slit or a circular hole at a position above the liquid level, and the lower end of the shaft is opened at the tip of the stirring blade to remove the liquid. Medium gas (gas, air)
The suction hole 3a and the air diffusion port 3b are connected to each other by a hollow hole in the drive shaft.

九円としても他の形状としてもよい。The diameter of the draft tube can be set arbitrarily, but it is desirable to set the diameter within a range of 1.5 to 5 times the diameter of the stirring blade. In the illustrated embodiment, the outer circumferential diameter of the shaft part of the aerator cover is made larger, and one or more slits 7 are bored in this plate-like connecting part, but even if the slits are made into nine circles, other It may also be a shape.

When the stirring blade 5 is driven, the stirring blade 5 rotates through the stirring shaft 3, and a vortex is generated in the liquid, and the tip 8 of the stirring shaft is rotated.
Negative pressure is generated in 1, and this negative pressure sucks gas, air, and other gases that enter the cover 4 through the suction hole 3a in the upper part of the hollow stirring shaft, and It is then discharged into the liquid through the air diffuser hole 5b at the lower end of the shaft. The gas released into the liquid becomes fine bubbles due to the turbulent flow in the draft tube and dissolves into the liquid. Further, the liquid flow rises after reaching the lower surface of the tank, flows into the trough tip through the slit 7, and repeats this process one after another.
これによって撹拌羽根よシ下部層では液体が充分に攪拌
され、ガスの混入溶解が行われるものである。As a result, the liquid is sufficiently stirred in the lower layer of the stirring blade, and gas is mixed and dissolved.

利点を有する。By guiding the mineral liquid flow through the draft tube according to the present invention, a sufficient flow rate can be given to the bottom of the aeration tank, and air bubbles can reach the entire tank to bring about a uniform aeration effect, and the draft tube This has the advantage that the air bubbles become finer due to the water flow, improving oxygen dissolution efficiency.
