外啮合柱塞式生物质颗粒燃料成型机的设计

摘要

结合活塞冲压式和模辊碾压式成型机连续出料及结构紧凑等优点,设计出一种外啮合柱塞式生物质颗粒燃料成型机.该成型机由电机驱动,动力经齿轮传输到压辊和环模上,通过压辊和环模的啮合运动使压辊柱塞销做类活塞运动将松散物料压入到环模成型孔中.松散物料经过持续的压缩运动并在摩擦力、侧向压力、颗粒间结合力等综合作用下最终被挤出成型孔形成颗粒燃料.介绍了外啮合柱塞式生物质颗粒燃料成型机的结构,分析了该机成型孔中物料的受力情况,并对压辊柱塞销进行了压杆稳定校核.这种外啮合柱塞式生物质颗粒燃料成型机是对生物质成型技术的一种新探索.%Coupled with the advantages of continuous discharge and compact structure of piston extruder machines and die and roller briquette machines,external meshed biomass pellet fuel molding equipment is designed.The machine is driven by electromotor,with loose material pressed into the forming hole by the engaging movement between the plunger-ram and ring die when the power is transmitted to modeling parts though the gear system.Under the comprehensive action-the friction,the lateral pressure and boned force in the particle,the material is compressed to biomass pellet.This paper introduces the construction of the machine in detail.The force of the material in the forming hole is analyzed,and the stability of the plunger-ram is checked.The biomass pellet fuel maker with external meshing is a new exploration to the biomass molding technology.
