Abstract: Taking the composite fermentation （aerobic anaerobic combined） tower device as the research object, the solid three-dimensional solid model of the composite fermentation tower was established by Solidworks, and the composite fermentation tower was simplified. The ANSYS Workbench finite element analysis software was used to identify the characteristics of the joint surface, and the finite element model of the important parts of the composite fermentation tower was established. Through the combination of theoretical calculation and finite element analysis, it is found that the screw shaft has less force, the blade is subjected to large force, and the force at both ends of the blade is the largest. The thickness of the upper right end of the diaphragm is too small to withstand the pressure of the material.
