Electric sweeping vehicle vacuum dust control system research

摘要

Sweeping Vehicle is an important tool to beautify the city environment with the characteristics of low cruise speed, less driving power consumption, and small operating area, which provides a good application prospect for the development of the electric sweeping vehicle. The characteristics of excellent stability at low speed, efficient energy conversion, convenient operability, and environment-friendly make it the first choice for cleaning road surface. In the study, the structure of vacuum dust collection system without sweeping brush is adopted in the designed electric sweeping vehicle. What is more, no dust particles generate when a sweeping vehicle is dumping. Therefore, it is worthy of the name "clean" vehicle. Firstly, electromotor and exhaust fan model is established, the joint performance between working electromotor and exhaust fan and the electromotor efficiency features are analyzed. Combining with the driving speed, it is analyzed that the suction and subsidence system's influence on the effect of dust collection. Taking into account coupling of the dust control system and the working state of the vehicle, vacuum dust control structure is designed, the dust removal efficiency is analyzed and the simulation is conducted. Finally, the dust-free dumping is realized. The result shows that, comparing traditional sweeping vehicle, electric sweeping vehicle system energy consumption is reduced by about 50%, noise is lowered significantly, direct emissions don't exist, and working time can meet the demand of regional cleaning.
