Description of drawings
Fig. 1 is embodiment 1 structural representation provided by the invention.
Fig. 2 is embodiment 2 structural representations provided by the invention.
Among the figure, submersible machine 1, impeller 2, air water mixed stirring device 3, gas-water mixture 31, retarding mechanism 4, diffuser 5, pipeline 51, mounting sleeve 6 is installed bracing frame 61, floating member 62, air access tube 63, positioning body 7.
Embodiment
Embodiment 1:
As shown in Figure 1; The multi-functional aerating apparatus of this microkinetic comprises submersible machine 1, below submersible machine 1, is provided with speed reduction unit 4, and impeller 2 is arranged below speed reduction unit 4; Below impeller 2, be provided with air water mixed stirring device 3; Submersible machine 1 links to each other with retarding mechanism 4 input terminuss through electric machine main shaft, and the output terminal of this retarding mechanism 4 links to each other with impeller 2, and air water mixed stirring device 3 is provided with diffuser 5.Air water mixed stirring device 3 comprise be tubular and up and down two ends all have bell-mouthed gas-water mixture 31, diffuser 5 is connected with gas-water mixture 31, diffuser 5 comprises plurality of conduits 51, pipeline 51 lower ends are connected with gas-water mixture 31.
In the present embodiment; Be fixed with mounting sleeve 6 on the submersible machine 1; Be provided with installation bracing frame 61 in the upper end of mounting sleeve 6; Install on the bracing frame 61 and be fixed with floating member 62, install on the bracing frame 61 and be fixed with the air access tube 63 that links to each other with mounting sleeve 6, pipeline 51 upper ends are connected with mounting sleeve 6.Therefore, present embodiment is suspended in the treating pond, and the lower end of air water mixed stirring device 3 does not have restraint device.The mounting sleeve 6 here is a connection mechanism, also is gas transmission mechanism simultaneously.
During use, the present invention is suspended in a certain position in the treating pond through buoyancy.When submersible machine 1 running, main shaft drives retarding mechanism 4 runnings of submersible machine 1 are slowed down back impeller 2 with very slow rotating speed rotation through retarding mechanism 4; The lift that impeller 2 rotations produce makes liquid from top suction; Slowly flowing downward arrives in the gas-water mixture 31 below the impeller 2, and will from the air cutting of diffuser 5, pulverize, mix the back to around diffusion, thereby airborne oxygen is passed to the mud in the treating pond; Played the effect of aeration aerating; Active sludge around driving simultaneously flows, and makes that mud is in the state that stirs that does not stop in the pond, plays the effect of stirring.Because the diameter of impeller 2 is big, rotating speed is slow, it is slower therefore to drive flow rate of fluid, but flow is not little, and the bump loss between the fluid is slowed down little, and energy consumption reduces, and efficient improves.
Embodiment 2:
As shown in Figure 2, in the present embodiment, gas-water mixture 31 is fixing through positioning body 7.That is, gas-water mixture 31 is fixed on the bottom of treating pond through positioning body 7.All the other all with embodiment 1 roughly the same, do not do and give unnecessary details.
Specific embodiment described herein only is that the present invention's spirit is illustrated.Person of ordinary skill in the field of the present invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used submersible machine 1 morely, impeller 2, air water mixed stirring device 3, gas-water mixture 31; Retarding mechanism 4, diffuser 5, pipeline 51; Mounting sleeve 6 is installed bracing frame 61, floating member 62; Air access tube 63, positioning body 7 terms such as grade, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; It all is contrary with spirit of the present invention being construed to any additional restriction to them.
