Abstract

A centrifugal self-priming mixed and inverted-umbrella shaped aerator is disclosed. A plurality of three-phase mixing tube sets is distributed on a surface of a wheel body (1), 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 (1), multiple layers of guide cylinders arranged concentrically extend downward from a bottom of the wheel body (1) with a plurality of vertical siphons distributed on an inner wall of each of the layers of guide cylinders, 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, each of the three-phase mixing tubes has one end attached to an edge of the wheel body (1) and has the other end communicating with the corresponding siphon, and each of the siphons is provided with a negative-pressure suction tube at a joint with the corresponding three-phase mixing tube.

Claims

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.

2. The centrifugal self-priming mixed and inverted-umbrella shaped aerator of claim 1,

wherein the plurality of three-phase mixing tube sets includes a first three-phase mixing tube set, a second three-phase mixing tube set, and a third three-phase mixing tube set, which are uniformly distributed on the surface of the wheel body;

wherein the first three-phase mixing tube set comprises a plurality of first mixing tubes, the second three-phase mixing tube set comprises a plurality of second mixing tubes, and the third three-phase mixing tube set comprises a plurality of third mixing tubes, wherein the first mixing tubes, the second mixing tubes, and the third mixing tubes are distributed on the surface of the wheel body apart from each other;

wherein the multiple layers of guide cylinders includes a first guide cylinder, a second guide cylinder, and a third guide cylinder being concentrically arranged on the bottom of the wheel body, wherein a tube diameter of the first guide cylinder is wider than a tube diameter of the second guide cylinder, and the tube diameter of the second guide cylinder is wider than a tube diameter of the third guide cylinder;

wherein the plurality of vertical siphons includes a plurality of first siphons, a plurality of second siphons, and a plurality of third siphons, the respective first siphons, second siphons, and third siphons being uniformly distributed on inner walls of the first guide cylinder, the second guide cylinder, and the third guide cylinder, respectively; and

wherein each of the first siphons communicates with one of the first three-phase mixing tubes and is provided with a first negative-pressure suction tube at a joint with the first three-phase mixing tube, each of the second siphons communicates with one of the second three-phase mixing tubes and is provided with a second negative-pressure suction tube at a joint with the second three-phase mixing tube, and each of the third siphons communicates with one of the third three-phase mixing tubes and is provided with a third negative-pressure suction tube at a joint with the third three-phase mixing tube.

3. The centrifugal self-priming mixed and inverted-umbrella shaped aerator of claim 2, wherein the first guide cylinder, the second guide cylinder, and the third guide cylinder extend vertically downward in tube diameter descending order into a step-like arrangement.

4. The centrifugal self-priming mixed and inverted-umbrella shaped aerator of claim 2, wherein a section of each of the first three-phase mixing tubes, the second three-phase mixing tubes, and the third three-phase mixing tubes have a rectangular, circular, triangular, or polygonal shape.

5. The centrifugal self-priming mixed and inverted-umbrella shaped aerator of claim 2, wherein a section of each of the first siphons, the second siphons, and the third siphons have a rectangular, circular, triangular, or polygonal shape.

6. The centrifugal self-priming mixed and inverted-umbrella shaped aerator of claim 2, wherein the first three-phase mixing tube set, the second three-phase mixing tube set, and the third three-phase mixing tube set are distributed on an upper surface or a lower surface of the wheel body.
