摘要
针对目前国内外生物质原料种类多、生产效率低、生产成本高及设备振动剧烈、部件磨损严重等问题,利用虚拟样机和有限元分析技术,结合成型试验研制了一种新的三柱塞式秸秆煤成型机。该机具当成型模具锥角为15°、成型温度为180℃、玉米秸秆原料含水率11%～17%时,成型燃料块的密度可达1.1 g/cm3以上,单位热值可达4 300 kJ以上,可与优质煤相媲美。三柱塞式秸秆煤成型机的生产效率比传统两柱塞式成型机提高了近50%,成本降低了33%,成型率可达到99%,寿命增加了近两倍。三柱塞式秸秆煤成型机具有对原料适应性强、生产效率高、产品成本低、运行平稳等特点,是特别适合广大农村朋友的新型多功能压缩成型机,目前已被正式选入辽宁省农机购置补贴目录。
In view of the diverse types of biomass materials, low production efficiency, high production costs, strong vibration of equipment and heavy wear of parts, etc. , a new three-phmger straw coal fuel molding machine was developed with the virtual prototype and finite element technique based on the molding experiment. When the cone angle is 15°, the molding temperature is 180℃, and the water content in materi- als is 11% - 17% , the density of the molded straw coal can be above 1.1 g/cm3 with the per unit heat value of more than 4 300 kJ, which is as good as the excellent coal. The production efficiency of the three-plunger straw coal fuel molding machine is raised by about 50%, the costs was cut down by 33%, the molding rate can be as high as 99% , and the service life is nearly tripled. With the advantages of strong adaptabil- ity to various raw materials, high production efficiency, low costs and smooth running, the three-plunger straw coal fuel molding machine is particularly suitable for rural people, and its purchase has been subsidized in Liaoning Province.
