Blade, aeration combined typed bleeding machine

[0011] By the attachment figure 1 As shown in -3, a paddle and gas-filled combined aerator of the present invention includes an electric motor 2, a high-pressure fan 3, a speed reduction mechanism connected from top to bottom, and a paddle wheel 9 and a storage device connected to it. Air bag 11, air distribution pipe 12 and pontoon 13; the motor 2 is surrounded by a wind deflector 1, which also plays a waterproof role; the output shaft of the motor directly drives the main shaft of the high-pressure fan 3, and the outlet pipe of the high-pressure fan 10 is connected to the air storage bag 11, the air storage bag is equipped with a sub-air pipe 12, which communicates with the water body; the main shaft of the high pressure fan is reduced by the planetary gear reducer 4, and then reduced by the bevel gear reducer 5, and the output shaft after changing the direction is connected The blade wheel is connected to the shaft 6, and the end of the connecting shaft is connected to the blade wheel 9; the box body of the bevel gear reducer 5 is fixed on the frame 8, and the blade wheel shaft seat 7 is also fixed on the frame; A pontoon 13 is provided, and the two are fixed by a hoop 14. All parts are placed on the pontoon so that the whole machine is suspended on the water surface; the gas distribution pipe 12 leads to the water body. It is distributed evenly in a water body of a certain depth in a radial manner, and a microporous exhaust pipe is connected to the end of each pipe;

[0012] The main shaft of the high-pressure fan is decelerated by the planetary gear reducer 4, and then reduced by the bevel gear reducer 5. The output shaft after changing the direction protrudes from both sides of the box of the bevel gear reducer 5, and its connected paddle wheel The connecting shaft 6 also extends to both sides, and its ends are respectively connected with a paddle wheel 9;

[0013] The air outlet pipe 10 and the air inlet pipe in the air guide hood 1 are both equipped with a silencer;

[0014] Said muffling device is attached to the inner wall of the air inlet and outlet pipes with foam plastic.
