Design And Application Of The Cluster Cut Tobacco Pneumatic Conveying System In Cigarette Factory

Pneumatic conveying technology in tobacco, electric power, chemical, food, medicine and other industries to be widely used.Cigarette Factory pneumatic conveying technology has already been widely applied in making and packing workshop:wind wire, silk plant stem wind, dust the room two times such as dust treatment using negative pressure pneumatic conveying method.Cigarette machine wind wire (cut tobacco pneumatic conveying) system is a negative pressure pneumatic conveying system, using the fan in the pipeline to form negative pressure suction of wire feeder (feeder) in tobacco, with a certain rate of transport to the cigarette making machine wire box set (by machine).Conventional system pipe network design using dendritic branching type, wire feeding system network complex.Volume compensation usually have a single centralized compensation, compensation in two ways.But the inherent characteristics of pipeline with resistance of each branch is balanced be congenitally deficient, hydraulic balance debugging difficulty, wire feeding machine and the tobacco shred feeder in different forms, cigarette machine group to wire randomness, volume compensation are difficult to control and other aspects of the objective factors make the whole system resistance fluctuation, single cut tobacco conveying speed are difficult to control and.The general wind wire feeding system is air compensation device, but the presence of compensation device to adjust the delay, unable to truly conveying speed stability and energy saving coexist. So cut tobacco feeding speed is not stable, tobacco shred broken high is the conventional pneumatic conveying of cut tobacco two urgent problems to be solved.Based on this, the authors change train of thought, research and design of a new constant pressure control bundle pipe type wind wire feeding device, it is using a bundle tube instead of general branch network, automatic compensation, constant air volume control principle of wind wire feeding complete device, overcomes the inherent properties of pneumatic feeding system defect.lt has the following characteristics:1)Convenient installation, modular components;2)Speed control of stable, small fluctuations;3)Tobacco shred broken rate is low;4)System energy saving.This paper discusses the new wind system design on three key components:cluster when the pipe network, high damping air centralized compensation, intelligent single resistance trimming device.Adopt a variety of control means for combining the control network system hydraulic balance system of wind speed, stability and low energy consumption operation.The design in a cigarette factory practice application of the process to obtain a bigger echo.
