LPG罐车节水清洗设备研发与参数优化研究

Development and Parameter Optimization of LPG Tank Car Water Saving Cleaning Equipment

为实现LPG罐车节水清洗的目标,提出了一种将机械刮刷清洗与高压水射流清洗相结合的新型清洗方式,并利用Solidworks软件对爬壁射流清洗小车进行了结构设计与三维建模,利用动量矩定理推导出喷刷机构的转速方程,建立了射流入射角及压紧力与转速的关系,从而得出最优转速下的射流入射角和压紧力组合。通过对喷刷机构进行运动仿真分析,得出了在保证清洗无遗漏前提下的小车最大行进速度。最后对新型清洗系统的能效分析表明,相比于目前在用的三维旋转射流冲洗,新清洗系统在水耗能耗以及设备成本方面都有着极为明显的降低,社会效益和经济效益显著。

To achieve the goal of water saving and cleaning for LPG tank cars.The structure design and three-dimensional modeling of the wall-climbing jet cleaning trolley were carried out by using Solidworks.The rotational speed equation of the spray-brushing mechanism was deduced by using the momentum theorem.The relationship between the jet incidence angle and the compression force and the rotational speed is obtained,and the combination of the jet incidence angle and the compression force under the optimal rotational speed is obtained.Through the motion simulation analysis of the spray brushing mechanism,the maximum traveling speed of the car is obtained under the premise of ensuring the cleaning without omission.Finally,the energy efficiency analysis of the new cleaning system shows that compared with the current three-dimensional rotating jet washing,the new cleaning system has a very significant reduction in water consumption,energy consumption and equipment costs,and social and economic benefits are remarkable.
