Coupled Vibration Sorting of Waste Plastic Film Based on D'Alembert Principle and Parameter Optimization Design
To improve recovery efficiency and utilization value of waste plastic film,a coupled vibration sorting method for waste plastic film was proposed.On the basis of d'Alembert principle,kinetic equations of the proposed method was established to analyze influencing factors of sorting effects and determine evaluation indexes of sorting effects.Optimiza-tion design variables of waste plastic film coupled vibration sorting equipment were determined,an optimized objective function was established,and an optimization procedure was written to obtain the optimized parameters of the waste plastic film coupled vibratory sorting equipment.The waste plastic film coupled vibration sorting equipment was developed,and the proposed kinetic equations were verified.The results show that the best sorting effect is achieved when the vibration angle of vibration deck is 48.63°,the angular velocity of vibration motor is 27.62π rad/s,and the lateral and longitudinal inclination angles of vibration bed surface are respectively 9.41° and 12°.The results of the verification experiment are similar to those of the optimization procedure,which verifies correctness of the established kinetic equations.Compared with the traditional wind vibration sorting method,the proposed method increases the sorting distance by 18.66% in the same time,and the sorting effect is better,which verifies effectiveness of the proposed method.
