Claim Text:
1. A centrifugal self-priming mixed and inverted-umbrella shaped aerator, comprising: an inverted-umbrella shaped wheel body having blades distributed on the wheel body, and a plurality of three-phase mixing tube sets distributed on a surface of the wheel body, wherein each of the three-phase mixing tube sets comprises a plurality of three-phase mixing tubes distributed dispersedly on the surface of the wheel body; and multiple layers of guide cylinders being arranged concentrically and extending downward from a bottom of the wheel body, wherein a plurality of vertical siphons are distributed on an inner wall of each of the layers of guide cylinders; wherein each of the three-phase mixing tube sets corresponds to one of the layers of guide cylinders, and the number of the siphons distributed in each of the layers of guide cylinders is the same as the number of the three-phase mixing tubes of the corresponding three-phase mixing tube set; wherein each of the three-phase mixing tubes has one end attached to an edge of the wheel body and has the other end communicating with the corresponding siphon; and wherein each of the siphons is provided with a negative-pressure suction tube at a joint with the corresponding three-phase mixing tube, one end of the negative-pressure suction tube being directed toward the exterior of the wheel body to communicate with the atmosphere and the other end of the negative-pressure suction tube extending into the three-phase mixing tube in a direction which is the same as an ejecting direction of water flow in the three-phase mixing tube.
