It is communicated with mixing chamber 4.
The course of work of the embodiment of the present invention is as follows: compressed gas is inputted from the inflating port 6 at 4 top of mixing chamber, in mixed gas
Under the action of high-speed rotating helical blade 8 in room 4, gas pressure increase is entered in air cavity 331, then from blade 31
The air inlet of hollow cavity 34 enters hollow cavity 34, and the outer half of mixing chamber 4 is finally output to from the gas outlet of hollow cavity 34.Water from
Water inlet 21 is input to mixing chamber 4；Compressed gas is mixed with water in the periphery of impeller, forms mixing wastewater with air liquid.It is high-speed rotating
Impeller carries out fly-cutting to mixing wastewater with air liquid, forms tiny steam bubble, tiny steam bubble incorporates in water rapidly, finally in impeller
Under the action of from each runner 41 of mixing chamber spray.
The embodiment of the present invention propose submersible agitating aerator, blade 31 be equipped with one end communicated with inflating port 6, the other end and
The hollow cavity 34 that mixing chamber 4 communicates.Hollow cavity 34 becomes the air inlet runner that inflating port 6 arrives 4 outer half of mixing chamber.From hollow cavity 34
Gas outlet output high speed rotation gas, be mixed to form mixing wastewater with air liquid with water.Since gas is with impeller high speed rotation, have
Very high kinetic energy, is quickly dissolved into water, therefore the gas content in the mixing wastewater with air liquid is higher, under the cutting of impeller 3, shape
At tiny steam bubble can quickly incorporate in water, improve the rate of transform of oxygen, gas-liquid mixed effect is good, be aerated it is high-efficient.2 He of bottom cover

As preference, the wheel hub 33 be equipped with air cavity 331, the air cavity 331 respectively with 34 phase of inflating port 6 and hollow cavity
It is logical.In order to improve gas-liquid mixed effect, it is necessary to guarantee inflating port 6 input gas in mixing chamber through high-speed rotating helical-blade
The effect of piece 8 increases gas pressure, enters in air cavity 331.But in use, blade 31 can not stall, not
It is fixed.Wheel hub 33 is the rotor of output shaft axle end for being fixed on submersible pump 7.Air cavity 331, leaf are set on wheel hub 33
The hollow cavity 34 of piece 31 is communicated through the air cavity 331 of wheel hub with inflating port 6, and structure is relatively simple, is worked more stable.It is preferred that
, the upper end of helical blade 8 is located in mixing chamber 4, and the lower end of helical blade 8 is located at the entrance of air cavity 331.In this way, air blower
Compressed air enter in mixing chamber 4, due to the high speed rotation of the helical blade 8 in mixing chamber, air is driven to enter gas
Then the top of chamber 331 is flowed into air cavity 331.
As preference, the wheel hub 33 includes the inner ring and outer rings being arranged concentrically, and inner ring and outer rings are fixedly connected, inner ring
Air cavity 331, the rotor axis connection of inner ring and submersible pump 7 are formed between outer ring, outer ring is connect with blade 31.The structure is formed
Air cavity 331 be annular air cavity, compressed gas from inflating port 6 input, under the action of high-speed rotating helical blade 8, high pressure
Air accumulation is into annular air cavity.Blade 31 is distributed in one week of annular air cavity so that gas can from annular air cavity even into
In the hollow cavity 34 of each blade, gas-liquid mixed effect is improved.
As preference, labyrinth seal structure 5, and labyrinth are equipped between 33 outer ring of wheel hub and mixing chamber 4 of the impeller
Sealing structure 5 is in air cavity 331.It is sealed by labyrinth seal structure 5, so that the compressed gas inputted from inflating port 6 is complete
Portion is output in mixing chamber 4 by the hollow cavity 34 of blade, ensure that gas-liquid mixed effect.If gas passes through from inflating port 6
Gap between impeller and mixing chamber 4 enters in mixing chamber 4, then gas does not pass through the high speed rotation of impeller, and mixed effect is poor.
In addition, labyrinth seal structure 5 is arranged between 33 outer ring of wheel hub and mixing chamber 4, on the one hand guarantee the height entered in air cavity 331
Fast gas will not generate leakage phenomenon, and gas is all introduced into hollow cavity 34；On the other hand, due to static 4 He of mixing chamber
Relative motion is formed in the cavity of top of the high-speed rotating helical blade 8 in air cavity 331, to guarantee compressed air in spiral
Under the drive of blade 8, gas pressure increase is made to be rapidly introduced into the top (i.e. the top of air cavity 331) of wheel hub 33.
As preference, the wheel hub 33 is equipped with intercommunicating pore 332.One end of intercommunicating pore 332 is connected to air cavity 331, separately
One end is connected to hollow cavity 34.It is connected between air cavity 331 and hollow cavity 34 by intercommunicating pore 332.Gas in air cavity 331 is through even
Through-hole 332 so that gas is evenly distributed in hollow cavity 34, and is uniformly exported, is mixed with water even into hollow cavity 34, is improved
Gas-liquid mixed effect.
As preference, the quantity of the intercommunicating pore 332 is identical as the quantity of blade 31, and a blade 31 is correspondingly arranged one
A intercommunicating pore 332.The hollow cavity 34 of each blade 31 is connected to by an intercommunicating pore 332 with air cavity 331.In each blade 31
Gas be evenly distributed, be greatly improved gas-liquid mixed effect.
As preference, the submersible agitating aerator further includes baffle 32, and baffle 32 is fixedly connected on blade 31
Hollow cavity 34 in.Baffle 32 can make gas steadily from outlet for being oriented to the flow direction of gas in hollow cavity 34
Mouth output, mixes with water, improves gas-liquid mixed effect.
As preference, the baffle 32 be plane or curved surface, and from the air inlet of blade 31 to blade 31 go out
Port direction, baffle 32 tilt down from inside to outside.Under the guiding for the baffle 32 being obliquely installed, gas inclines from gas outlet
It exports, the gas and liquid mixture being mixed to form with water, under the turning effort of impeller 3 also diagonally downward, improves to bottom of pond obliquely
Aeration effect, while to the medium in pond rise stirring action.More preferred, the number of baffle 32 in each blade 31
Amount is 1~3.The baffle 32 of fair amount is set, enables gas more uniform and is distributed in blade 31, and is uniform
