菌渣颗粒燃料固化成型机的设计与试验

Design and Experiment on Biomass Pellet Densifying Machine for Residue

针对食用菌生产中的菌渣丢弃导致环境污染及综合利用率低的问题,依据生物质碾切挤压成型原理,研究设计了菌渣颗粒燃料固化成型机,并对其核心部件环模与压辊的结构参数、力学特性等进行了分析。通过对栽培过后的金针菇菌渣成型试验,试验结果表明:该机生产率为945.5kg/h,吨料电耗71.43kW·h/t,颗粒燃料的成型率为96.4%,机械耐久性为97.2%,颗粒质量密度为1.24 g/cm3,颗粒含水率为10.1%,均符合生物质颗粒燃料成型要求。整机工作平稳,成型可靠,物料适应性强和操作环境无粉尘等优点,性能满足设计要求。

Aiming at the present situation regarding the handling of edible fungi discarding , which leads to the environ-mental contamination and lower ratios of comprehensive utilization .According to the principle of biomass pellet grinding , cutting and extrusion molding , and takes analysis in the structural parameters and mechanical properties of its core com-ponent -circular mould and pressed roller , the biomass pellet densifying machine for edible fungi residue was designed . Through a densifying test of enoki mushroom residue , the results of machine performance test showed that the productivity was 945.5kg/h, tons of power consumption was 71.43kW· h/t, forming rate of particle fuel was 96.4%,mechanical durability was 97.2%,particle density was 1.24g/cm3 ,and particle moisture content was 10.1%.All the parameters can meet the requirements of biomass pellet fuel forming , which has durable , stable and reliable performance , as while as materials adaptable and no dust in the operating environment .
