As an efficient treatment technology for kitchen waste disposal,high pressure extrusion technology is increasingly widely used.The host frame of beam-column high pressure extrusion equipment was designed.Solid modeling was carried out by SolidWorks software,and finite element analysis was carried out by importing it into ANSYS Workbench software.The host frame of beam-column high pressure extrusion equipment with good fatigue resistance was designed,strength and stiffness both meet the requirements.Simultaneously,the application case of beam-column high pressure extrusion equipment was introduced.
