Impeller unit rotates；It is characterized in that：The impeller unit includes wheel hub and blade；The lower end of every blade is disposed as the edge of a knife
Shape, forms rotating blade；The bottom top sets fixed blade, and fixed blade includes axial main blade and radially auxiliary knife
Piece；Axially shearing is secondary for the rotating blade and axial main blade composition, and rotating blade and radial direction auxiliary blade constitute radial shear
It is secondary.
The rotating blade that blade lower end is formed is cut with the axial main blade, radial direction auxiliary blade composition fixed on blade respectively
Cut pair；After switching on power, high-velocity flow is allowed to form negative pressure through mixing chamber, and air is inhaled into and mixes with liquid, mixed liquor from
Mixing chamber perimeter outlet flows out.When entering fiber-like in the cavity of mixing chamber and winding object, cutter sweep is by its fly-cutting
Into broken section, and runner by mixing chamber is flowed outwardly.At the same time, when air flows through impeller, the rotating blade pair on impeller
Bubble mixed liquor carries out fly-cutting, and bubble is broken into more tiny microbubble, and fine and closely woven bubble improves air with aeration
The contact area of medium, effectively increases the rate of transform of oxygen.
Specifically, the axial main blade and radial direction auxiliary blade are double-edged razor blade, quantity is 3 ~ 5.Two-edged knife
Piece is that positive and negative can act as blade and use, and tow sides can be installed arbitrarily, and interchangeable another side continues to make after a surface wear
With.
Specifically, the quantity of the rotating blade is 3 ~ 5.Number of blades is excessive, increases cost, and number of blades is very few,
Be unfavorable for fully cutting, experiment find, should in the range of most beneficial at low cost realize fully cutting effect.
Further, the surrounding of mixing chamber is uniform is provided with the passage for flowing out mixed liquor.It is equal for ensureing aerator surrounding
Even dissolves in containing aerobic air.
It is an advantage of the invention that：On the one hand can be to entering into mixing chamber cavity fiber substance fly-cutting, removal
Twister in impeller unit；On the other hand under the cutting of rotating blade, the rate of transform of oxygen is effectively increased.

Specific embodiment
As shown in figure 1, the present invention includes air inlet pipe 1, submersible pump 2, inlet plenum 3, impeller unit 4, mixing chamber 5, fixation
Blade 6 and bottom 7.Air enters inlet plenum 3 by air inlet pipe 1, then is inhaled into mixing chamber 5, therefore, inlet plenum 3 is air
The middle transition body entered into before mixing chamber 5, for ensureing that gas can uniformly enter mixing chamber 5.
High-velocity flow forms negative pressure in the cavity of mixing chamber 5, and for sucking the air in inlet plenum 3, gas exists with water
Air-liquid mixed liquor is formed in mixing chamber 5, the surrounding of mixing chamber 5 is uniform to be provided with the passage for flowing out mixed liquor, it is ensured that aerator
Surrounding is uniformly dissolved in containing aerobic air, is entered into the liquid of surrounding, so as to complete aerobic process.
After submersible pump 2 is assembled, inlet plenum 3 and mixing chamber 5 are assembled successively on the armature spindle of its lower end, bottom 7 is used for
Closing mixing chamber 5 bottom, the armature spindle of submersible pump 2 stretches into connection impeller unit 4 in mixing chamber 5, and impeller device 4 revolves
Turn, the top of bottom 7 also sets up fixed blade 6.
Fixed blade apparatus 6 are assemblied on bottom 7 by fastener, and bottom 7 is fixed on mixing chamber.
As shown in Fig. 2 impeller 4 includes wheel hub 41 and blade 42；The lower end of each blade 42 is set to edge of a knife shape, forms rotation
Rotor piece 45；Rotating blade 45 is located at the lower end of blade 42, and rotating blade quantity is 3 ~ 5.After gas is flowed into mixing chamber, a part
Along the discharge of the top of blade 42, the portion gas form gas flow（Ⅰ）43, gas flow（Ⅰ）43 remove inlet end and outlet side
Outer to be contained by blade 42, gas flow direction is horizontal arrow direction indication in Fig. 2；Another part flows into the bottom of blade 42, shape
