Design and Optimization of Drum Structure of New Invertible Filter Centrifuge

The invertible filter centrifuge attracts extensive attention in recent years due to its advantages such as closed operation and complete unloading.To further improve its separation efficiency and make the equipment lighter and higher efficient,the drum design in the centrifuge should be optimized.Then,its structure is designed to obtain the initial wall thickness and opening value which are used as the optimization parameters used to establish a multi-objective mathematical optimization model,reduce the mass and increase the filtration area.Under the condition of ensuring the strength and stiffness,the optimal parameters are obtained by selecting different parameters.The data analysis results show that the drum mass is reduced by 13.25%,the area of filtration is increased by 56.28%,thus improving the separation efficiency of the equipment effectively.
