单等级片烟箱式存贮系统的设计与应用

Design and Application of Case Storage System for Strips of Single Grade

为满足卷烟制丝环节单等级片烟预处理的工艺要求,解决传统柜式片烟存贮占地面积大、贮柜数量多、贮柜型号不统一等问题,通过合理设计系统的装箱方式、存贮形式、翻箱形式及料箱结构,采用实时含水率折算与静态秤计量组合技术,设计了单等级片烟箱式存贮系统。应用效果表明,该系统存贮能力为1900料位(每料位120～150 kg),满足了卷烟生产企业精细化加工处理工艺要求,保证了各等级片烟的精确配比,配比精度提高0.29百分点,生产用煤降低5.46×105kg/年,片烟造碎率减少0.17百分点,有效提升了叶组配方精度的保证能力,提高了系统单位空间存贮密度,实现了分组加工模式下片烟存贮与配比过程的柔性化生产。

In order to meet the technology requirements for pretreatment of single grade strips during primary processing and overcome the shortcomings of traditional silo system, such as large site area, a great number of silos of variform silo types, a case storage system for single grade strips was configured via designing of case filling means, storage means, case tipping means and case structure, and incorporating real-time moisture content conversion and static balance metering. The results of application showed that： the storing capacity of the system was up to 1900 cases （120-150 kg/case）, which satisfied the need of fine tobacco processing and accurate blending of various strips, and the blending precision raised by 0.29 percentage points. Coal consumption reduced by 546 tons per year, the rate of tobacco breakage decreased by 0.17 percentage points; it ensured the accuracy of tobacco blend and effectively raised the storage density per unit space of the system, and made strip storing and blending a flexible process.
