When the aeration head 22 performs aeration, if the aeration head 22 rotates to the lower part of the sliding sleeve 34 and the blades 36, the upward air flow formed by the aeration head 22 can jack up the sliding sleeve 34 and the blades 36 upwards, so that the lifting effect of the blades 36 is realized, and the stirring effect of the blades 36 on sewage still can be generated in the lifting process, so that the reliable stirring effect of the sewage is realized in the process of sliding the blades 36 and the sliding sleeve 34 up and down, and the aeration effect of the sewage is obviously improved.
The bottom of the sliding sleeve 34 is provided with a baffle 340 extending in a horizontal direction, and the aeration head 22 intermittently sprays air flow toward the bottom of the baffle 340. The baffle 340 increases the contact area with the air flow ejected by the aeration head 22, thereby ensuring that the aeration head 22 can realize the driving function of the sliding sleeve and the blades 36 while aerating. Further, the aeration heads 22 intermittently spray air flow towards the bottom of the baffle 340, that is, during the rotation of the turntable 21, one or more aeration heads 22 move to the lower side of the baffle 340 during the rotation, so that the lifting effect of the baffle 340 and the sliding sleeve 34 and the blades 36 can be realized, and when the aeration heads 22 rotate away from the baffle 340, the sliding sleeve 34 and the blades 36 slide downwards under the action of gravity, so that the reciprocating up-and-down movement of the blades 36 on the tank 1 is realized, no special power source is required, and the structure is compact, and meanwhile, the stirring and aeration effects on sewage in the tank 1 are improved.
The aeration heads 22 are arranged on the turntable 21 at intervals, and one aeration head 22 intermittently rotates to the lower part of the baffle 340. Thus, by intermittently pushing the baffle 340 by one aeration head 22, the acting time of the air flow sprayed from the aeration head 22 to the baffle 340 is reduced, and the sliding range of the blades 36 can be increased, thereby further improving the stirring effect on the sewage.
The baffle 340 is separated from the vane 36 in the vertical direction. In this way, on one hand, the blades 36 can be prevented from collision with the baffle 340 in the rotating process, and on the other hand, when the blades 36 rotate, the sewage in the tank body 1 can form a circular flow in the vertical plane in the tank body 1, so that the disturbance effect of the blades 36 on the sewage is improved, and the aeration effect is further improved.
In summary, the present utility model is not limited to the preferred embodiments, but includes all equivalent changes and modifications in shape, construction, characteristics and spirit according to the scope of the claims.
