生物质环模制粒机产能与能耗分析

Analysis on Capacity and Energy Consumption of Biomass Circular Mould Granulator

摘要:

分析环模制粒机技术参数和物料特性参数对设备产能与能耗的影响规律，可为产品的系列化设计提供理论依据。在对环模制粒机成型过程和机构受力分析的基础上，建立了设备产能与能耗模型，绘制了不同设备技术参数与物料特性参数下的环模制粒机产能和能耗等值线。等值线分布规律表明，环模直径越大、转速越高，对设备产能和能耗的影响越明显；与其他参数相比，物料与辊模之间的摩擦因数对设备产能影响更大，改进辊模表面结构形式或表面材料是提高设备生产率的有效途径；辊模直径比对设备产能的影响比对设备能耗的影响大，辊模直径比越大，设备单位产能能耗越低，因此，在满足设备结构与技术要求的前提下，应尽量增大辊模直径比。

Abstract:

By analysis on influence of machine technical parameters and material parameters on equipment capacity and energy consumption, a theoretical basis for product seriation design can be provided. Capacity and the energy consumption modeling were done, and isolines of capacity and energy consumption at different equipment technical parameters and material properties were drawn, based on the analysis of forming process and mechanics. Isoline distribution show that the greater mould diameter and mould rotation speed are, the more obvious influences of them on capacity and energy consumption become. Compared with other parameters, the frictions coefficient between material and roller as well as between material and circular mould have greater influence on equipment capacity, it can enhance the equipment capacity to improve the surface structure or surface material of the roller and circular mould ; the influence of diameter ratio of roller to circular mould on the equipment capacity was larger than its influence on the energy consumption, the larger the parameter is, the lower the energy consumption for certain capacity becomes, so it is necessary to enlarge the parameter as much as possible.
