摘要
为了提升海参吸捕装置吸嘴性能以提高系统的效率,课题组在传统直管状吸嘴的基础上,提出了内涡旋式吸嘴和外涡旋式吸嘴2种新式结构。通过对直管状吸嘴、锥形罩吸嘴、内涡旋式吸嘴和外涡旋式吸嘴进行FLUENT仿真分析,筛选出管口轴线高度和吸拾能力均最强的吸嘴;通过正交试验法得到最优的吸嘴结构;最后通过搭建实验平台进行吸嘴实验验证。仿真与实验结果表明:内涡旋式吸嘴管口轴线高度和吸拾能力均最强,且内流道涡旋式引导板宽度20 mm、内流道涡旋式引导板的高度30 mm和内涡旋式引导板的螺距130 mm时效率最高。该研究有利于提高海参吸嘴在实际应用中的吸捕效率。
In order to boost the performance of suction nozzle of the sea cucumber suction and catching device to improve the efficiency of the system,two new structures of inner vortex suction nozzle and outer vortex suction nozzle were proposed based on the traditional straight pipe suction nozzle.Through the FLUENT simulation analysis of straight pipe suction nozzle,conical cover suction nozzle,inner vortex suction nozzle and outer vortex suction nozzle,the suction nozzle with the highest nozzle axis height and the best suction capacity was selected.The optimal structure of suction nozzle was obtained by orthogonal test,and the experimental platform was established to verify the nozzle experiment.The simulation and experimental results show that the inner vortex nozzle has the highest axis height and the strongest suction capacity,and the efficiency is the highest when the width of the inner channel vortex guide plate is 20 mm,the height of the inner channel vortex guide plate is 30 mm and the pitch of the inner vortex guide plate is 130 mm.This study is conductive to improve the efficiency sea cucumber suction nozzle in practical application.
