摘要
真空吸尘式清扫车是一种利用负压工作的新型清扫车辆。吸尘口是其气路系统的关键部件,对整台清扫车的吸尘能力、吸尘效率以及工作可靠性等各方面有着决定重要的影响。以吸尘口为研究对象,采用UG软件建立吸尘口的三维模型,使用Gambit软件进行网格离散,运用Fluent软件进行流场分析,对不同的卷边吸尘口进行吸尘效果的对比研究,设计出了一种前曲面挡板的吸尘口,并进行了气固两相流的运动仿真验证。研究表明:前宽后窄、带有前曲面挡板的吸尘口具有良好的吸尘效果。
The vacuum cleaning vehicle is a new kind of sweeper which uses negative pressure. Its dust suction mouth, as a key component of its gas path system, plays an important role in dust-sucking capability, cleaning effi- ciency, reliability and other aspects of the sweeping vehicle. Taking the dust suction mouth as research object, a three-dimensional model of the dust suction mouth was built with UG software. Grid was generated with Gambit soft- ware, and flow field was analyzed with Fluent software. Theeffects of different structures of the dust suction mouth with curled edges on the dust suction were compared; a dust suction mouth with front curved plate was designed, and simulation of the gas-solid flow motion was completed. The simulation results show that the dust suction mouth with wide front edge or narrow rear edge or curved front plate has excellent dust suction effects.
