Structural Optimization Of Roller Konjac Mill Basic Parts

As a versatile vegetable,konjac is rich in a variety of functional ingredients such as konjac sugar,ceramide,and alkaloids,and has the functions of clearing heat and swelling,promoting blood circulation,reducing blood suga,reducing fat,and preventing cancer and laxation.Konjac refined powder is a concentrated product rich in the main nutrients of konjac.It has great nutritional ingredients and unique properties,and has extremely broad application prospects in the fields of food,medicine,health care and industry.As domestic konjac refined flour has less manufacturing equipment,this paper studies and analyzes the common equipment for domestic grain crops processing-roller mill on the basis of similar foreign milling technology.?1?As the main load-bearing component of the mill,the frame is often large in size and weight due to work safety.In order to reduce production costs,this article takes the FMFQK₁100/25 mill frame as the research object,and optimizes it for the purpose of weight reduction.The specific content is as follows:First,the frame was subjected to force analysis and load calculation,and Creo3.0 was used to establish a three-dimensional model of the frame,which laid the foundation for the finite element analysis of the frame.Then,the finite element analysis software ANSYS was used to perform static analysis and simulation of the frame.State analysis and harmonic response analysis,according to the overall deformation,stress change and modal shape of the frame,combined with the actual working condition of the mill,draw the conclusion that the weight reduction of the frame can be optimized;finally,the topology optimization design method is applied,Optimize the weight reduction design,and reduce the weight of the rack by12%after optimization.The finite element analysis of the optimized rack shows that the structure of the optimized rack is reasonable and meets the design requirements.?2?In order to improve the production efficiency of the mill and the service life of the feeding system,Optimize the design as follows:First,collect and calculate the relevant parameters during the suction process of the mill.In order to compare and analyze the influence of materials on the structure of different suctionPipes,Creo was used to establish four suction pipe models,which laid the foundation for the numerical simulation of the suction pipe.Then,the fluid simulation software is used to perform fluid simulation analysis.Finally,the pressure cloud diagram and velocity vector diagram of the fluid region in the tube are compared and analyzed.The results show that the suction pipe structure with an included angle of 30°is the most reasonable.?3?Simulate and analyze the material flow process in the cavity of the mill and optimize the cavity model.The specific contents are as follows:The combined model of the fluid domain cavity was established.Based on the numerical simulation of the suction tube,Fluent was used to study and analyze the material flow in the cavity of the mill.The results show that the material will form a vortex in the cavity,which affects the powder extraction efficiency of the mill.Discuss and analyze the specific methods to reduce the vortex zone inside the mill cavity.The rigid wall can be changed to a flexible wall,and the internal volume of the mill cavity can be enlarged.These two specific measures can be used to reduce the vortex zone.Use Creo3.0to establish an optimized cavity model,which can be seen from the material movement trajectory diagram:the vortex inside the cavity of the optimized mill is significantly reduced,It provides a reference for optimizing the structure of the mill frame.
