Overall Design And Research On Garbage Suction System Of Pure Electric Suction Sweeping Vehicle

With the rapid development of economic and the acceleration of urbanization process, people’s environmental requirements are improving constantly. With the urbanization development, making the number of offices factories and other public places fast-growing, but the sanitation cleaning problems is becoming increasingly serious. In order to reduce the labor intensity of the pavement cleaning staff and improve their work efficiency, sanitation cleaning work has already started to use the road cleaning machinery, but the existing surface cleaning equipment in domestic are mostly converted from truck modified chassis, with internal combustion engine driver, bulky and inflexible, and have serious problem of noise and exhaust. Also those sweeper operating device are driven by hydraulic equipment, with complex pipeline system. Based on above problems, develop electric road cleaning equipment that is pollution-free, flexible operation, and also with convenient operation has important practical significance.In this thesis, the electric suction sweeping vehicle was used as the research object. By comparing the basic configuration of the existing suction sweeping vehicles in domestic and foreign, the basic institutions of the pure electric suction sweeping vehicle was put forwarded in this article. The disc brush cleaning system and the dust collection system was designed by studying the mechanism of the dust cleaning and suction. The focus of this article is the fluid mechanics simulation and optimization on dust sucking mouth and gravity settling chamber. The main work of the article includes:First of all, the overall structure of the pure electric suction sweeping vehicle was designed based on its operating conditions, the vehicle was divided into chassis drive system, disc brush cleaning system, vacuuming system, electrical control system and vehicle power supply system. Combined with the characteristics of the electric suction sweeping car, the double motor timely all-wheel-drive dynamical systems was put forwarded into use in this article by using the driving motor and the operation motor. Specially, in order to achieve the timely four-wheel drive, the single-ended input and double-ended output device was designed for the operation motor. Also the parameter of the driving motor, operation motor and the vehicle power supply system was matched and calculated, and the corresponding parameters also achieved;Secondly, the basic structure, the enhance electric putter and the avoidance spring of the disc brush system is designed and matched based on the study of the cleaning mechanism, also the three-dimensional structural model of the disc brush system is established according to the matched parameters;Thirdly, the circulation vacuum dust removal system was designed by studying the mechanism of the dust Suction and removal. Aiming to reduce gas path system energy consumption and improve cleaning job performance, the fluid mechanics simulation tool Fluent was used in the dust sucking mouth and gravity settling chamber simulation and optimization, then find the higher job efficiency, lower energy consumption dust sucking mouth and gravity settling chamber that is suitable for the pure electric suction sweeping vehicle;In this article, on the basic of the latest research work of electric road sweeper in domestic and foreign, the drive system structure of the pure electric vehicle was designed. Specially, the key work is the circulation vacuum dust removal system simulation and optimization. this study has a certain guiding significance for the pure electric suction sweeping car research and development.
