摘要
为解决打叶复烤中因高速皮带抛料风分器风分载荷高、抛料角度固定而导致风分效果不佳等问题,设计了一种重质分流风分器并对一级风分流程进行了改进。采用机械辊进行抛料,通过导料板调节片烟的抛料角度和距离,增加重质叶出口并将其直接输送至二级打叶设备,实现了轻质叶与重质叶的精准分离。以贵州烟叶复烤有限责任公司铜仁复烤厂生产加工的WCC3F烤烟烟叶为对象进行测试,结果表明:(1)与高速皮带风分器相比,重质分流风分器风分效率提高6.57百分点,重质叶分流比例达到45%,叶中含梗率控制在0.65%以内;(2)改进后打叶机组进入二级打叶的重质叶含水率和温度分别提高1.5百分点和7.3℃,大中片率提高0.69百分点,片烟的造碎率控制在0.25%以内,叶中含梗率降低0.23百分点。该技术可为提升打叶机组的生产性能提供支持。
To improve the separation efficiency of green leaf thresher,a pneumatic separator with heavier tobacco bypass was designed,meantime,the processing flow of the first stage pneumatic separating was modified accordingly.A mechanical roller is used to project tobacco,a deflector plate is used to adjust the projecting angle and distance,thereby to increase heavier tobacco output and deliver it directly to the second stage thresh,and to separate lighter tobacco from heavier tobacco precisely.The new separator was tested with tobacco of grade WCC3 F in Tongren Redrying Factory of Guizhou Tobacco Redrying Limited Corporation,and the results showed that:1)Compared with traditional pneumatic separator,the separation efficiency of the newly designed separator raised by 6.57 percentage points,the proportion of bypassed heavier tobacco reached 45%,the stem content in strips was less than 0.65%.2)The moisture content and temperature of the heavier tobacco that went into the second stage thresher raised by 1.5 percentage points and 7.3℃respectively,the large and medium-sized strip percentage increased by 0.69 percentage points,the breakage rate of strips was less than 0.25%,and the stem content in strips reduced by 0.23 percentage points.This technology provides a support for promoting the production performance of threshing lines.
