Abstract


Tobacco stems pneumatic conveying and pneumatic collection signed as flexible layout, easy management, and high degree of automation , which in the cigarette industry has been widely used. Makeup air branch pipe tobacco quantitative method of transport is the major domestic tobacco conveying one of the ways it is transmitted back through the air branch pipe tobacco install fill valve, when the cigarette machine does not suck filament fill the same amount of air flow into the whole system working crew tobacco conveying stability. Although the makeup air way to ensure the stability of the system transporting tobacco , but the energy consumption point of view, the additional amount of makeup air is not doing useful work on the system , it increases the load on the system , thereby increasing the energy consumption . In response to this situation, combined Terrier signed pneumatic collection system , this paper presents tobacco pneumatic conveying and Terrier signed pneumatic collection combined into a systematic approach , namely the use of tobacco delivery systems complement air volume as a Terrier signed collect wind part , and to stable wire feeding conveyor speed, on this basis, and complex systems analysis, its main contents are as follows : firstly analyzes the branch pipe quantitative complement wind tobacco pneumatic conveying systems and Terrier signed pneumatic collection system characteristics of each proposed complex systems may . Second, the use of network theory, graph theory, create a composite system pipe network hydraulic conditions mathematical model, using basic circuit analysis method iterative method for cross pipe network mathematical model of the system is solved to obtain a composite system of transport and different conditions tobacco stems sign collection wind speed and air pressure . Then use specific examples of the composite system tobacco pneumatic conveying section and Terrier signed pneumatic collection part separately stability calculation analysis and velocity analysis , the following conclusions : composite system can meet the tobacco stable transportation and Terrier signed collecting conveyor , while the composite system of tobacco pneumatic conveying stability Terrier signed with pneumatic air volume collected increased the proportion is increasing. Finally, complex systems engineering examples and a separate system for energy consumption were compared and analyzed to obtain a composite system not only meets the actual needs of the project , but also has a significant energy saving effect , indicating that the composite system has great practical value and the promotion of significance.
