FY36型废烟支处理机中导流风扇的改进

Improvement of Deflector Fan in FY36 Tobacco Reclaimer

为解决FY36型废烟支处理机应用过程中残次烟支在进料口处被反复击打、剪断和遗漏拍打等问题,利用工作腔工作压力仿真技术对工作腔落料口端的导流风扇进行了改进。将导流风扇的外形设计为反鸟翼型,安装在进料口下方的主轴上,3片扇叶沿主轴均匀分布,安装角与主轴上橡胶打棒排列的螺旋升角相等,3片扇叶在轴截面的投影首尾相连接,导流角与螺旋升角成90°。应用效果表明,改进后螺旋导流风扇解决了工作腔中残次烟支输送不流畅等问题,回收烟丝中含纸片量从(20±5)片/500 g降低到≤10片/500 g,纸筒完整率由不足40%提高到≥75%,残次烟支扒净率由不足85%提高到98%,有效提高了设备效能。

Some waste cigarettes were beaten and sliced repeatedly while the others might be intact at the inlet end of FY36 tobacco reclaimer, therefore the deflector fan at the discharge end of working chamber was improved with the simulation technology of working pressure in working chamber. A reversed bird＇ s wing like profile was designed for the deflector fan, which was installed on the main shaft under the inlet end. The three blades of the deflector fan were equally distributed along the main shaft, their installing angle was the same as the helical angle of the rubber-beater. The projections of the said blades on the axial section connected end to end, and the deflection angle was perpendicular to the helical angle. The results of application showed that the improved helical deflector fan solved the problem of waste cigarette staggering movement in the working chamber, the paper chips content in reclaimed tobacco reduced from 20±5 to ≤ 10 piece/500 g, the integrity rate of cigarette paper tube and the rate of tobacco detached from the paper tube raised from less than 40% to ≥ 75% and from less than 85% to 98%, respectively.
