水葫芦压缩打包机设计与工艺参数优化

针对水葫芦容积密度小、含水率高,不利于资源化利用的问题,研制了一种基于液压打包原理的水葫芦压缩打包机,确定了压缩装置、出料装置等零部件的主要结构参数,完成了控制系统的硬件搭建与软件编程。为探究机器运行参数对压缩打包工艺性能的影响,以喂入量、切碎度、保压时间为试验因素,以打包密度、产量、含水率为指标,采用综合评分法,通过单因素试验和正交试验确定各因素的最优工艺参数组合。试验结果表明,当喂入量为7.0±0.1 kg,切碎度为6.75±2.25,保压时间为10 s时,水葫芦压缩打包工艺性能最优,打包密度为446.6 kg/m~3,产量为238.8 kg/h,含水率为91.27%,综合得分0.941,上述结果可为水葫芦压缩打包机设计与工艺参数优化提供参考依据。

Design and Process Parameters Optimization of Water Hyacinth Compressing-Packing Machine

Water hyacinth has small bulk density and high water content, which is not conducive to resource utilization. This study developed a water hyacinth compression-packing machine based on the principle of hydraulic packing, determined the main structural parameters of compressing device, discharging device, etc. other parts, and completed the hardware construction and software programming of the control system. In order to explore the impact of machine operating parameters on compressive packing process performance, this paper took feeding rate, mincing degree, dwell time as experimental factors and bale density, yield and water content as targets, and determined the optimal combination of technological parameters through single-factor and orthogonal experiments by comprehensive scoring method. The results showed that the excellent water hyacinth compressing-packing process performance was obtained when feeding weight was 7±0.1 kg, mincing degree was 6.75±2.25, dwell time was 10 s, and packing density was 446.6 kg/m3, yield was 238.8 kg/h, water content was 91.27%, and comprehensive score reached 0.941. The above results provided references for designing water hyacinth compressing-packing machine with optimized technological parameters.
