摘　　要：为了提高贻贝清洗工序的自动化程度和清洗效果,降低工人劳动强度,设计了一种集打散和清洗工序为一体的新型滚筒式贻贝清洗设备,利用摩擦清洗方式代替当前使用的振动清洗方式,清洗后的贻贝表面附着物和足丝连接更少,该设备提高清洗加工自动化程度和降低加工人员配置的同时,设备占地面积更小。采用Solidworks软件和Simulation模块对设备进行三维建模和相关零部件的有限元仿真,并对该设备进行样机制作和相关试验。结果显示:清洗过程中,贻贝破损数量和滚筒转速成正比,清洗所用时间和滚筒转速成反比,结合破损数量和清洗时间两曲线,确定滚筒最佳转速为30 r/min,最佳清洗时间为32s,清洗速度为375颗/min(约25 kg/min)。该设备对发展贻贝船上加工模式具有借鉴意义。In order to improve the automation degree and cleaning effect of the mussel cleaning process and reduce the labor intensity of the workers,a new drum-type mussel cleaning equipment that integrates the dispersing and cleaning processes has been designed.The friction cleaning method is used instead of the current vibration cleaning method.After cleaning,there are fewer attachments and byssus connections on the surface of the mussels.This equipment improves the automation degree of cleaning process and reduces the staffing of the processing.At the same time,the equipment covers a smaller area.Solidworks software and Simulation module are used to carry out three-dimensional modeling of the equipment and finite element simulation of related parts,and prototypes and related experiments are performed on the equipment.The results show that during the cleaning process,the number of mussels damaged is directly proportional to the rotation speed of the drum,and the time used for cleaning is inversely proportional to the rotation speed of the drum.Combining the two curves of the number of damage and the cleaning time,the optimal rotation speed of the drum is determined to be 30 r/min,the optimal cleaning time 32 s,and the cleaning speed 375 pieces/min(about 25 kg/min).The equipment is of great significance for the development of the mussel on-board processing model.
