摘要
为了充分发挥叶丝加料的技术优势,提高叶丝加料的应用效果,分析测试了叶丝加料不同加工参数对加料效果的影响。结果表明:①烟片增温补偿蒸汽开度为10%时,切丝综合质量较好;②与切丝后叶丝不筛分相比,经孔径1mm振筛筛分后,加料机筒壁粘附量明显减少,干燥后叶丝碎丝率较低,加料均匀性较好;③随着加料前HT蒸汽压力、叶丝含水率(在16%~22%的范围内)、加料机排潮风机频率、补偿蒸汽开度的增大,加料的均匀系数和料液有效利用率呈先升高后降低的趋势;④随着加料前HT蒸汽压力的增大叶丝加料机筒壁物料粘附量呈上升趋势,压力越大,粘附物越多。
To improve the effects of cut strip casing, the influences of technical parameters on casing effects were tested and analyzed. The results showed that: 1) The comprehensive quality of strip cutting was better at the compensation steam valve opening of 10%. 2) Via screening by a vibration sieve with 1 mm mesh after strip cutting, the cut strips adhering to casing cylinder wall were obviously reduced, the percentage of broken strands in dried cut strips was lower and the uniformity of casing was better. 3) The coefficient of casing uniformity and the effective utilization rate of casing increased first and then decreased with the increase of HT steam pressure before casing, the moisture content (within a range of 16%-22%) in cut strips, the exhaust fan motor frequency and compensation steam valve opening. 4) The cut strips adhering to casing cylinder wall increased with the rise of HT steam pressure before casing.
