Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
In the embodiment shown in Fig. 2-5, a kind of multidirectional submerged aeration machine, it comprises compression ring compressor 4, blower fan seat 6, inlet pipe 2, compressed air pipe 3, and parts such as pedestal 11.Above compression ring compressor 4, be provided with a rain cover 1.Compression ring compressor 4 links to each other by carriage 5 with blower fan seat 6.Ball float 8 is connected with the bottom of blower fan seat 6 by ball float bearing 7.The upper end of gas cylinder 9 links to each other with blower fan seat 6, and the lower end links to each other with the upper shed of pedestal 11.The lateral opening of pedestal 11 is connected with the top of diving hollow shaft motor 13.The two ends of motor pull bar 10 are connected with the bottom of diving hollow shaft motor 13 and blower fan seat 6 respectively, play load and reinforcement effect.End at diving hollow shaft motor 13 is provided with pod 12, its forward water screw 14 and diving 13 coaxial connections of hollow shaft motor, in sewage during aeration, this water screw rotates with motor at multidirectional submerged aeration machine, play promoting to stir sewage, make it fully hold the effect of oxygen.Also be provided with impeller 15 co-axial in this water screw front portion with it, its front view as shown in Figure 6, this impeller rotates equally when aeration, plays the convergence airflow, with the speed that increases airflow and the effect of range.The upper end of support 16 is connected with the bottom of pedestal 11, supports the body of this multidirectional submerged aeration machine.In the present embodiment, pedestal 11 is the three-dimensional pedestal, as shown in Figure 8.This pedestal 11 also can be the multidirectional pedestal of other specifications in actual applications, and for example two to pedestal or four-way pedestal, as shown in Fig. 7,9.
