风送烟丝系统卷烟机落料器风力特性

摘要

In order to solve the problem of energy consumption, air leakage rate and stability in the pneumatic cut tobacco feeding system, the field measurement and statistic analysis methods were used. The pressure drop and air leakage rate of the discharger in the pneumatic cut tobacco feeding system and the air velocity in the cut tobacco feeding tube were analyzed. The results show that the regularity changes of pressure drop in the discharger and the air velocity in the cut tobacco feeding tube are obvious, but the air leakage rate is not apparent during the cut tobacco suction process. The consequence has guiding significance for the design, initial investment, energy saving of the pneumatic cut tobacco feeding system and the design of discharger.%为了解决风送烟丝系统的能耗大、漏风和稳定性差的问题,文中采用现场实测与统计分析相结合的方法,对风送烟丝系统落料器中的压降和漏风量,以及送丝管内风速进行研究.结果表明,在系统吸丝过程中,落料器中的压降及送丝管内风速呈明显规律性变化,而漏风量的变化规律性不明显.结果对风送烟丝系统设计、初投资和节能降耗,以及落料器设计有指导意义.
