Detailed description of the invention
Embodiment 1, as it is shown in figure 1, a kind of surface aeration machine, including floating drum 1 and be installed on floating drum 1
Motor 21, aial flow impeller 24, the level of described floating drum is provided with the water absorption channel connected up and down to centre
12, be provided with the water inlet 11 connected with water absorption channel 12 below described floating drum, the top of described floating drum be provided with
The outlet 13 of water absorption channel 12 connection, described motor 21 is located at above outlet 13 and is vertically arranged, electric
Machine output shaft is underlying and connects the kuppe having pump shaft 22, the lower section of motor 21 to be provided around pump shaft 22 setting
23, the corresponding outlet 13 of kuppe 23 is arranged, and the bottom of described pump shaft 22 is exposed from kuppe 23, stretches
Enter water absorption channel 12 and above-mentioned aial flow impeller 24 is installed.
In water absorption channel 12, motor 21 drives aial flow impeller 24 to rotate and produces powerful lift extraction
Sewage in cesspool, sewage is entered by water inlet 11, then throws to be formed in the air water by outlet 13
Mist, sewage water smoke aloft can be fully contacted with air, and the oxygen in air is transferred in sewage for antibacterial
Breathe.
Wherein, as shown in Figure 4, the surface of floating drum be provided with several when surface aeration machine water outlet, with current
The current dispersion protruding 14 of percussion, arranges having the beneficial effect that of these current dispersion protruding 14:
(1) pontoon surface increase current dispersion projection after, surface aeration machine when water outlet, water impact
Current dispersion is protruding to be refined the globule, increases current and air contact surfaces increases aeration rate, improve surface and expose
The aeration effect of mechanism of qi.
(2) smooth pontoon surface is easily deformed adding man-hour, and intensity is relatively low, and arranges current dispersion projection
Floating drum intensity can be increased, it is ensured that surface is unlikely to deform in process of production.
