摘　　要：针对目前市场上生物质气化炉锁料器运送物料时频繁出现卡顿、卡塞,导致锁料器叶轮叶片发生扭曲变形的现状,设计了一款防卡塞生物质成型燃料锁料器。课题组在理论和ANSYS软件分析基础上,采用可拆卸式刀片结构设计实现了多物料调节;采用在进料口加长刀挡板,对进料口与出料口错边结构设计防止物料在进料口发生剪切。为了测试设计结构的效果,设计了一套实验测试系统;将实验数据、功率参数曲线与实际运行情况对比,研究了改进结构改善叶轮受力的效果。结果表明:可拆卸式刀片结构能减少物料卡塞,降低噪声;加长刀挡板、进料口与出料口错边减少卡顿,使运行更平稳。改进后叶轮的使用寿命约为原结构的4倍,且锁料器的卡塞、卡顿情况得到了有效改善。A anti-jamming Biomass Fuel Locker was designed to solve the problem that the occurrence of caton and kasse caused distortion of the impeller blades of the locker when transporting materials for biomass gasifier lockers.Based on theoretical analysis and ANSYS software analysis,a removable blade structure was adopted to realize multi material adjustment;it adopted the design of adding the long knife baffle at the feeding port,the staggered edge structure of the feed port and the discharge port to prevent the material from cutting at the feed port.A set of experimental testing system was designed to test the effect of the design structure.Experimental data comparison,power parameter curve and actual operation were carried out to study the effect of structure on improving impeller force.Experiments show that the detachable blade structure can reduce material jam and reduce noise;the lengthened knife baffle and the staggered edge structure of the feed port and the discharge port can reduce the carton to make the operation more stable,the service life of the impeller is increased by4times.The designed structure can effectively improve the casse problem of the locker.
