基于COMSOL的牡蛎超声协同清洗仿真分析与试验
Simulation analysis and experiment of ultrasonic synergistic cleaning of oysters based on COMSOL
摘要
Abstract
To address the problems of incomplete cleaning of oyster shells and low efficiency in traditional oyster cleaning machines,this paper studies the ultrasonic cooperative cleaning technology and develops an ultrasonic cooperative cleaning device for oysters.Based on the COMSOL Multiphysics finite element simulation technology,the distribution of the ultrasonic field was simulated,and the influence laws and pressure distribution of the ultrasonic cleaning frequency,cleaning cross-section height,and the number of transducers on the sound pressure and sound pressure level in the ultrasonic cleaning domain were clarified.The research shows that the optimal energy distribution of the ultrasonic field is achieved when the ultrasonic cleaning frequency is in the range of 25-45 kHz,the cleaning cross-section height is-125 mm,and the number of transducers is 10.The sound pressure value range is(2.5-4.8)×104 Pa.A prototype was manufactured,and the cleaning performance was verified.By exploring the effects of feeding rate,cleaning time,and ultrasonic cleaning frequency on the overall cleaning performance of the machine,the results show that the order of influence of each factor on the oyster impurity removal rate is feeding rate＞ultrasonic cleaning frequency＞cleaning time.Under the operating conditions of an ultrasonic cleaning frequency of 28 kHz,a cleaning time of 5 minutes,and an oyster feeding rate of 1 150 g,the impurity removal rate of the device was 5.63％.This study can provide a reference for the development of ultrasonic cleaning devices for oysters.关键词
