【摘要】 由于石化资源存量的日益减少,同时燃烧这些燃料所带来一系列的环境问题受到前所未有的重视,生物质能源的开发和利用被世界各国关注。本文就发明专利号(201310595175.7)的新型齿辊式生物质成型机的试验机展开研究,对该机型的攫取角进行理论分析结果表明比普通的环模成型机更大,同时利用旋转阵列方法对辊齿和环模孔的干涉问题进行分析,得到按照设计尺寸齿辊和环模并不干涉;利用ABAQUS软件的对该机型的变形压紧区和压紧挤出区物料运动和应力情况进行模拟,以此为基础进行功率的计算,并就该机型成型情况试验测试,得到试验材料最佳成型转速和含水率下的比能耗,发现在含水率1 6%时,转速200prm时能耗降低13%,为其该机型的设计提供依据,为制定合理工艺参数做了必要的探索。更多还原

【Abstract】 Since the stocks of petrochemical energy is dwindling,and burning these fuels brings a range of environmental issues is facing unprecedented attention,the development and utilization of biomass energy have caused concern around the world.In this paper,we study on new type of biomass gear rolls forming machine,theoretically analyzed its grab corner.The results showed that the angle is greater than ordinary ring molding machine,and using rotating methods to research the roller gear and ring mold hole interference.The result is in accordance with the design and size of the teeth of the roller does not interfere with the ring mold;using ABAQUS software compression deformation zone area and pressing extrusion materials simulate the movement and stress conditions,then doing the power calculation,and testing for this type of molding conditions.Get the specific energy consumption of materials in the best forming speed and moisture content.The conclusion is when the water content was 16%and the speed is200 prm the energy consumption is low.The models provide a basis for the design,Reasonable parameters for the models to do the necessary exploration.更多还原
