The use of the present invention is described in detail below.
Air sent by the blower passes through the middle air inlet pipe, the air inlet pipe conveys the air into the lower communicating pipe 103 of the lower-layer diffusing cover 206, part of the input air enters the air guide pipe and then enters the cavity 101 of the top-layer diffusing cover 205, and the other part of the air enters the cavity 101 of the lower-layer diffusing cover 206 through the lower communicating pipe 103. The air entering the cavity 101 passes through the air outlet hole 104 to form big bubbles, the big bubbles rise again and are cut by the toothed part I105, rise and pass through the air guide channel, are cut by the toothed part II 107, continue to rise and move upwards obliquely along the conical plates 201 and 202, are cut by the toothed parts III 203 and 204 at the same time until medium and small bubbles are formed, overflow along the outer edges of the conical plates 201 and 202 and move upwards on the water surface. Because the diameters of the top layer diffuser 205 and the lower layer diffuser 206 are different, the micro bubbles cut by the two diffuser are different in the contact surface of air and water in the vertical direction in the rising process, so that the contact area of aeration water is increased, the contact and mixing time of air and water is increased, the diffusion and transfer of oxygen are enhanced, and the oxygen is continuously dissolved in water to meet the demands of microorganisms (membranes).
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
