Upper portion is equipped with a plurality of second bubbles cutting pin fin, a plurality of second bubbles cutting pin fin along the inside wall circumferencial direction evenly distributed of aeration barrel along the inside wall in the aeration barrel. The utility model discloses a cutting apart layer upon layer of straight half blade, first bubble cutting pin fin, second bubble cutting pin fin, with the bubble cutting for minute bubbles, and with on every side muddy water mixture intensive mixing, increased the mass transfer rate and the oxygen utilization ratio of oxygen, possess higher aeration efficiency, its operation is reliable and stable, is difficult to take place to block up long service life.
Description
Technical field
The utility model relates to a kind of rotational flow aeration device, and a kind of aeration cylinder assembly of rotational flow aeration device, belongs to aerator technical field specifically.
Background technology
Aerator is a kind of common aerating apparatus.During use, air is passed into aerator and opens, for the aeration medium in aeration tank provides oxygen and the effect of gas-liquid mixed flow, make aeration medium high efficient mixed, especially can improve the dissolved oxygen content of medium.
At present, general is produce pressure air by gas blower to the method for oxygenation in sewage lagoon, is delivered in sewage by oxygen by aerator.The operating performance of aerator directly has influence on efficiency and the success or failure of sewage disposal.It is high to there is cost of manufacture in traditional rotational flow aeration device, inefficiency, and service area is little, runs the shortcomings such as not steady.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus provides a kind of aeration cylinder assembly, possesses higher aeration efficiency, stable and reliable operation, blocking is less likely to occur, long service life.
According to the technical scheme that the utility model provides, aeration cylinder assembly comprises aeration cylindrical shell, it is characterized in that: aeration tube inner bottom part center is provided with diversion column, diversion column both sides are respectively equipped with a straight half vane, in aeration cylindrical shell, middle part is provided with multiple first bubble cutting ailhead along inner side-wall, and multiple first bubble cutting ailhead is uniformly distributed along the inner side-wall circumferential direction of aeration cylindrical shell; Aeration cylindrical shell internal upper part is provided with multiple second bubble cutting ailhead along inner side-wall, and multiple second bubble cutting ailhead is uniformly distributed along the inner side-wall circumferential direction of aeration cylindrical shell.
Further, aeration cylindrical shell is cylindrical.
Further, the upper and lower two ends of diversion column are spheric.
Further, the diameter of the second bubble cutting ailhead is greater than the diameter of first bubble cutting ailhead.
Compared with the prior art the utility model has the following advantages:
The utility model structure is simple, compact, reasonable, through the segmentation layer by layer of straight half vane, first bubble cutting ailhead, the second bubble cutting ailhead, bubble is cut into small bubbles, and fully mix with the mud mixture of surrounding, add rate of mass transfer and the coefficient of oxygen utilization of oxygen, possess higher aeration efficiency; Its stable and reliable operation, blocking is less likely to occur, long service life.

Description of reference numerals: 1-aeration cylindrical shell, 2-diversion column, the straight half vane of 3-, 4-first bubble cutting ailhead, 5-second bubble cutting ailhead.
Embodiment
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Fig. 1 ~ 4, the utility model mainly comprises columniform aeration cylindrical shell 1, aeration tube 6 inner bottom part center is provided with diversion column 2, and diversion column 2 both sides are respectively equipped with a straight half vane 7, and straight half vane 7 can revolve mixed pulverizing to the empty G&W entering aeration cylindrical shell 1.
Described diversion column about 2 two ends are spheric, can to the bubble formation guide functions risen.
In aeration cylindrical shell 1, middle part is provided with multiple first bubble cutting ailhead 4 along inner side-wall, and multiple first bubble cutting ailhead 4 is uniformly distributed along the inner side-wall circumferential direction of aeration cylindrical shell 1.
Aeration cylindrical shell 1 internal upper part is provided with multiple second bubble cutting ailhead 5 along inner side-wall, and multiple second bubble cutting ailhead 5 is uniformly distributed along the inner side-wall circumferential direction of aeration cylindrical shell 1.
The diameter of described second bubble cutting ailhead 5 is greater than the diameter of first bubble cutting ailhead 4.In use, repeatedly pulverized bubble by first bubble cutting ailhead and the second bubble cutting ailhead, whipping performance is good, and the bubble of generation is even, and coefficient of oxygen utilization is high.
Principle of work of the present utility model is: during work, air enters the gas inlet bottom rotational flow aeration device by the inlet end of Y-tube, when aeration, air-flow rises with very high speed, mud mixture is around driven to rise together, through the segmentation layer by layer of straight half vane, first bubble cutting ailhead, the second bubble cutting ailhead, bubble is cut into small bubbles, and fully mixes with the mud mixture of surrounding, adds rate of mass transfer and the coefficient of oxygen utilization of oxygen.
The utility model structure is simple, compact, reasonable, through the segmentation layer by layer of straight half vane, first bubble cutting ailhead, the second bubble cutting ailhead, bubble is cut into small bubbles, and fully mix with the mud mixture of surrounding, add rate of mass transfer and the coefficient of oxygen utilization of oxygen, possess higher aeration efficiency; Its stable and reliable operation, blocking is less likely to occur, long service life.
