香蕉秸秆颗粒燃料固体成型机的设计与试验

针对中国热带农业区香蕉秸秆粗大、含水率高、秸秆固体成型设备少等问题,该文研究设计了香蕉秸秆固体成型机,确定了螺杆挤压装置、搅拌装置、挤出成型装置和排水装置等部件的主要结构参数。样机性能试验结果表明:该机生产率为358kg/h,颗粒燃料的成型率为95.4%,机械耐久性为96.7%,颗粒质量密度为1.35g/cm3,颗粒含水率为2.76%,符合生物质颗粒燃料成型要求。整机工作平稳,成型可靠,经济效益与生态效益明显,在中国热带农业区具有广阔的推广应用前景。

Design and experiment on biomass pellet densifying machine for banana stem

Aiming at the present situation regarding the handling of the coarse banana straws which are labor intensive, high water content, and unavailability of satisfactory straw solid molding equipment in the tropical agricultural areas of China, the biomass pellet densifying machine for banana stem was designed. The main structural parameters of screw extrusion device, mixing device, extrusion device and draining mechanism were determined. The results of machine performance test showed that the productivity was 358 kg/h, forming rate of particle fuel was 95.4%, mechanical durability was 96.7%, particle density was 1.35 g/cm3, and particle moisture content was 2.76%. The machine can meet the requirements of biomass pellet fuel forming, which has durable, stable and reliable performance, as while as obvious economical and ecological benefit. It will have the broad prospect of application in the tropical agricultural areas in China.
