Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in figures 1 and 2, a fermentation tank with mechanical and air double stirring comprises a tank body 1, wherein a stirring shaft 2 which is vertically arranged is arranged in the inner cavity of the tank body 1; a cylinder 3 with openings at the upper and lower parts is sleeved on the outer side of the lower part of the stirring shaft 2, and stirring blades 4 are arranged at the part of the stirring shaft, which is positioned in the inner cavity of the cylinder 3; the stirring blade is provided with three layers;
a horizontally arranged air distribution plate 5 is arranged right below the cylinder 3, the inner cavity of the air distribution plate 5 is hollow, and the inner cavity of the air distribution plate 5 is connected with a compressed air conveying pipe 6; the air inlet end of the compressed air conveying pipe 6 extends to the outer side of the tank body 1 and is used for being connected with a compressed air source; the upper surface and the lower surface of the air distribution plate 5 are respectively and discretely provided with a plurality of air outlet pipes 7, the top ends of the air outlet pipes 7 are in a plugging shape, and the outer circumferential wall of each air outlet pipe 7 is provided with a plurality of air outlet holes. In the utility model, the air distribution plate 5 is selected to be a circular structure, and the diameter of the air distribution plate 5 is larger than that of the bottom end of the cylinder 3.
