Design and Simulation of Grinding Structure for Kitchen Waste Disposer
To improve the performance of a kitchen waste processor.The grinding structure of a kitchen waste processor was redesigned,and the strength check and structural optimization of the grinding ring vertical knife of the main part of the grinding structure were carried out based on LSDYNA simulation software and SPH particle algorithm.The simulation results show that the maximum stress on the root of the grinding ring vertical knife when handling garbage is 36.97 MPa,which is much smaller than the yield limit of material Q235A stainless steel of 235 MPa,and according to the maximum stress value of the root of the vertical knife of the grinding ring and the plastic deformation of the garbage to be treated,the length of the vertical vertical knife of the grinding ring is determined to be 7 mm.Finally,the optimization scheme is tested in practice,and the test results show that the newly designed abrasive structure has a certain improvement on the performance of the kitchen waste processor and the structural strength is stable.
