摘　　要：针对目前我国生物质压块机存在的生产率低、能耗高及成型燃料质量低等问题，采用立式环模原理，设计了一种新型生物质压块机，设计了带有加热电阻和降温水道的环模，并以粉碎玉米秸秆为原料进行试验，试验结果表明，生产率为2．1t／h，吨功耗35．6kW·hit，整机噪声82dB（A），成型率为95．4％，成型密度为1．1g／cm^3，各项指标均达到设计及标准要求，启动时采用加热电阻，能够缩短预运行时间50～65min，正常生产时，燃料的温度能够降低20～30~C，生产率比未采用加热降温环模时增加5％。For the low productivity, high energy consumption and low briquette quality of biomass briquetting machine, the principle of vertical ring die was used. A biomass briquetting machine was developed. A ring mold with heating resistor and cooling waterways was designed. The crushed corn straw was taken as raw materials for the experiment. The experiment result showed that the production rate was 2. 1 t/h. Tons of power consumption was 35.6 kW- h/t. Machine noise was 82 dB （A）. The molding rate was 95.4%. The forming density was 1. 1 g/cm^3. The indicators could reach the design and standard requirements. It could shorten the pre-run time by 50 min to 65 min by using the heating resistor. The ring mold takes cooling device. The temperature of the fuel could be reduced by 20℃ to 30℃ and the production can be increased by 5% than non-adopted in normal production.
