Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
Embodiment 1: a kind of aerobic fermentation tank, referring to Fig. 1 to Fig. 5.
The agitating shaft 1 that it includes tank body 2, is set in 2 inner axis of tank body is set to paddle 9 on agitating shaft 1, peace
Loaded on tank body lower end and the stirring motor 11 that is connect with agitating shaft 1.
Specifically, it is hollow structure inside the agitating shaft 1 and forms airflow channel, and agitating shaft upper end extends to tank
At the top of body, and the air inlet 7 being connected to agitating shaft internal gas flow channel is offered in agitating shaft upper end；It is in the paddle 9
Hollow structure, and 9 surface of paddle is equipped with several stomatas 16 being connected to boring, the paddle contacted with agitating shaft 1
Side wall is equipped with the opening 15 being connected to 1 internal gas flow channel of agitating shaft, is entered after airflow channel airflow channel by opening 15 and is stirred
It mixes Ye Nei and is discharged out of stomata 16.
In the design, the paddle is three and interval setting from top to bottom, and any two are in water in three paddles
Plane is long to be arranged in angle, and the length of three paddles is identical；The stomata is round stomata, meanwhile, at least stirred described
