A corrugated groove 13 is provided in the inner cavity of the tank body 1 and around the sliding block 83;

[0022] See also Figure 1 、 Figure 2 and Figure 3 The aeration assembly 2 includes an annular tube 21, which is fixedly mounted at the bottom of the inner cavity of the tank body 1, and the top of the annular tube 21 is connected to a gas outlet 22;

[0023] See also Figure 1 、 Figure 2 and Figure 3 The right side of the annular tube 21 is connected to a bend tube 23, one end of the bend tube 23 passes through the outside of the tank body 1 and is connected to a filter 24, and the top of the filter 24 is connected to an air inlet pipe;

[0024] See also Figure 4and Figure 5 The end of the sliding block 83 away from the fixed frame 82 extends to the inner cavity of the corrugated groove 13 and is in sliding contact with the inner wall thereof. The inner cavity of the sliding cylinder 81 is in sliding contact with the surface of the sliding groove 10. By providing the corrugated groove 13, the sliding block 83 can slide inside it, so that the sliding block 83 can perform an up and down corrugated circular motion, thereby causing the dispersion net 84 to move up and down during the rotation process, thereby expanding the dispersion area;

[0025] See also Figure 4 , a protective shell 9 is provided on the surface of the rotating rod 52 and is located on the outside of the sliding groove 10. A through groove is provided on both the left and right sides of the protective shell 9. A blocking cloth 11 is fixedly installed at the bottom and bottom of the inner cavity of the through groove. By setting the use of the sliding groove 10, the sliding cylinder 81 can be limited so that it can only move up and down on the surface of the sliding groove 10;

[0026] See also Figure 4 , the surface of the fixed frame 82 is in sliding contact with the inner wall of the through groove, and the other end of the blocking cloth 11 is fixedly connected to the surface of the fixed frame 82. The blocking cloth 11 is a telescopic design. The blocking cloth 11 can block the through groove to prevent materials from entering the interior of the protective shell 9, and can move up and down with the fixed frame 82 without hindering the movement of the fixed frame 82;

[0028] During use, material is added to the tank body 1 through the feeding pipe 6, and then the motor 51 is started. The output shaft of the motor 51 drives the rotating rod 52 to rotate, so that the stirring plate 54 and the spiral blade 53 rotate at the same time, and the spiral blade 53 is used to transport the material below the inner cavity of the tank body 1 upward, and then the material is fully stirred by the stirring plate 54 to ensure that the microorganisms are in full contact with the material. The rotating rod 52 drives the protective shell 9 to rotate, and the rotation of the protective shell 9 drives the fixed frame 82 to rotate, so that it drives the dispersion net 84 to disperse the material. At the same time, it drives the sliding block 83 to make a corrugated circular motion inside the corrugated groove 13, thereby driving the dispersion net 84 to move up and down during the rotation process, thereby achieving the effect of dispersing the material over a large area. During the stirring process, the air is exhausted to the inside of the air inlet pipe through the external air pump, and is discharged through the filter 24, the elbow 23, the annular pipe 21 and the air outlet head 22 in sequence, thereby discharging sterile air into the tank body 1 to improve the reaction efficiency.
