摘　　要：为解决贻贝传统清洗方式劳动强度高、清洗效果差的问题,搭建了贻贝高压水射流清洗平台。以射流压力、靶距、入射角为变量,射流打击力和射流冲击压力为评价指标,对贻贝外壳进行高压水射流清洗试验;通过Design-Expert软件设计多因素组合试验,建立射流打击力和射流冲击压力的数学模型,使用Box-Behnken响应面寻优得出贻贝高压水射流清洗参数的最优组合;采用最优清洗参数进行射流清洗试验,以验证参数的有效性。结果显示:使用喷射角为65°,内径为2 mm的扇形喷嘴,在射流压力为9.66 MPa,靶距为99.88 mm,入射角为75.38°进行高压水射流清洗时,射流冲击压力为0.011 MPa射流冲击压力远小于贝壳整体曲面的承压能力,清洗后的贻贝表壳完整无裂纹,表壳附着的各类顽固污物基本去除,清洗效果相较于传统清洗方式得到显著提升。高压水射流技术应用于贻贝的清洗,能有效提高贝源的洁净程度和工业化精细处理水平,同时对其他双壳纲贝类的清洗也具有一定的借鉴意义。To solve the problems of high labor intensity and poor cleaning effect of traditional cleaning methods of mussels,a mussel high-pressure water jet cleaning platform was built.Firstly,high pressure water jet cleaning experiment was carried out on a mussel shell with jet pressure,target distance,and incident Angle as variables and jet impact force and jet impact pressure as evaluation indexes.Then,the multi-factor combination experiment is designed by Design-Expert software,and the mathematical model of jet impact force and jet impact pressure were established.The optimal combination of mussel high-pressure water jet cleaning parameters was obtained by using the Box-Behnken response surface;Finally,the optimized cleaning parameters are used for jet cleaning experiments to verify the effectiveness of the parameters.The results show that when the fan nozzles with a jet angle of 65°and an inner diameter of 2 mm are used for high-pressure water jet cleaning,the jet impact pressure is 0.011 MPa when the jet pressure is 9.66 MPa,the target distance is 99.88 mm and the incident angle is 75.38°.The jet impact pressure is far less than the pressure bearing capacity of the overall surface of the shell.The cleaned mussel watch case is complete without cracks,and all kinds of stubborn dirt attached to the watch case are basically removed.The cleaning effect is significantly improved compared with the traditional cleaning method.The application of high-pressure water jet technology in mussel cleaning can effectively improve the cleaning degree of the mussel source and the level of industrial fine treatment.At the same time,it also has a certain reference significance for the cleaning of other bivalves.
