Specific implementation mode
The present invention will be further described below in conjunction with the accompanying drawings：
A kind of centrifugal Aeration stirrer shown in referring to Fig.1, including motor 1, inlet plenum 2, main shaft 3 and aeration impeller 4.
One end of the main shaft 3 through inlet plenum 2 and by the output axis connection of shaft coupling 5 and motor 1, main shaft 3
The other end is connect with aeration impeller 4.
As one embodiment of the present invention, main shaft 3 uses stainless steel, has good antiseptic property, main shaft 3
It is connect by screw-thread fit with the impeller axle 41 of aeration impeller 4.
The main shaft 3 is hollow structure, and offers in 3 surface of main shaft in inlet plenum 2 and be connected to the inside of main shaft 3
The outer wall of air admission hole 31, the inlet plenum 2 is equipped with air inlet and is equipped with break-make ball valve 21 at air inlet；Break-make ball valve
21 can be used and manually control or Electronic control.
With reference to shown in Fig. 2, the aeration impeller 4 includes impeller axle 41, and equally distributed around the impeller axle 41
Blade uses four blades in the present embodiment, can adjust according to actual needs.
The blade is made of the centrifuge tube 42 and the reinforcing rib 43 that connects with centrifuge tube 42 of arc；The centrifuge tube
The other end of 42 one end opens far from impeller axle 41, centrifuge tube 42 is connected to by the air flue in impeller axle 41 with 3 inside of main shaft.
In 4 high-speed rotation of aeration impeller, will produce centrifugal force, air therewith by centrifuge tube 42 mouthfuls gone out by surge, oxygen
It is dissolved in the water, and reaches stirring and mixed effect.
As one embodiment of the present invention, it can also include support element 6, upper bearing (metal) is fixed on the support element 6
Seat 7, the inlet plenum 2 are fixed on the top of top chock 7, and inlet plenum 2 is fixedly arranged above motor cabinet 8, motor installation
In on motor cabinet 8.
The lower section of the top chock 7 is connected with step 10 by fixed connection pipe 9, and the top chock 7 is under
Upper bearing (metal) 11 and lower bearing 12 are separately installed in bearing block 10, the main shaft 3 is installed on by upper bearing (metal) 11 and lower bearing 12
In fixed connection pipe 9.The lower section of step 10 is equipped with mechanical seal 13 in the extension of main shaft 3, passes through locking nut
14 lock mechanical seal 13 and aeration impeller 4.
Working principle of the present invention is as follows：The present invention is placed in accessing pending water body, motor 1, the inlet plenum 2 on top
And 7 part of top chock is located above water body, the step 10 and impeller of 3 lower section of main shaft 3 and main shaft in fixed connection pipe 9
