FY10残烟处理机的改进及二次剥离系统的设计应用

Improvement of FY10 Tobacco Recovery Machine and Application of Secondary Stripping System

FY10残烟处理机在使用过程中存在处理效果不理想、筛分效率低、回收烟丝结构差、纸中含丝率高等问题,为此对FY10残烟处理机的筛分系统进行了改进并设计增加了一套独立的二次剥离系统。主要是:①残烟处理机出料振动筛分机由双层改为单层;②丝网更换为不易变形的板网;③在两台振动筛分机的板网下方增加弹力球;④二次剥离系统由提升喂料机、柔性剥离装置、圆型多层筛分机等组成。改造后FY10残烟处理机解决了烟末堵塞网孔且清理难的问题,回收烟丝整丝率平均值由56.93%提高到67.86%,碎丝率平均值由1.35%降低至0.34%,纸中含丝率平均值由27.45%降低至3.19%,提高了烟叶原料的利用率,降低了生产成本。

Aiming at the problems of low screening efficiency,high tobacco degradation and higher rate of tobacco remaining in paper,the screening system in FY10 tobacco recovery machine was improved as following： 1） changing the double-deck discharge shaker into a single-deck one;2）replacing wire screen with a screen plate;3） adding elastic balls under the screen plate of the two shakers.And an independent secondary stripping system was also added,which was composed of an elevating feeder,a gently stripping device and a disc type grading sieve.The application results showed that after improving,the problem of mesh blocking caused by tobacco dust was solved,the average proportion of long strands in recovered tobacco increased from 56.93% to 67.86%,while that of short strands decreased from 1.35% to 0.34%,the average rate of tobacco remaining in paper reduced from 27.45% to 3.19%,the utilization of tobacco was improved.
