摘  要能源化利用生物质原料秸秆，可大幅度的减少不可再生能源的开采，需要1吨标准煤才可以提供的热值可被2吨秸秆机制煤所代替，这大大的减少了地球不可再生能源的消耗，有效的保护地球上的生态环境。使秸秆资源能源化被利用的技术有许多，大致说来主要包括：炭化和活化、秸秆的干馏技术和燃烧发电、热解气化技术、压缩固化成型燃料技术等等。此外，我国第十二个五年计划也明确提出要推动我国秸秆能源化利用发展，提高可再生能源在我国能源消费结构中的比重。69266

本课题主要将秸秆粉进行碳化挤压成型，通过对各种秸秆成型机进行对比，并比较各自的优缺点，然后确定了螺旋式挤压成型的方式，确定方案后对各部分进行设计计算，包括电机的选型与计算，螺旋输送部分的设计计算，螺旋轴的设计与计算、二级减速器的设计计算以及传动轴的设计校核，轴承的选型，通过Proe三维软件对秸秆木炭压缩成型机的建模并进行动态仿真，利用CAD二维软件对整体结构进行绘制，完成了二维装配图以及部分零件图。

ABSTRACT

Straw biomass energy as an important, 2 tons of straw stalk energy-oriented use 1 tons of standard coal calorific value alternative, promotion of straw energy-oriented use, can effectively reduce energy consumption at a time. Straw energy utilization technology mainly include straw biogas (biological gasification), curing fuel of straw, straw pyrolysis gasification, direct combustion power generation and the way of straw carbonization, carbonization and activation, etc. "Twelfth five-year" period, to develop the straw biogas and straw curing fuel, to increase the proportion of renewable energy in energy structure.

This topic mainly will be carbonization straw powder extrusion molding, through comparing all kinds of straw molding machine, and compares their advantages and disadvantages, and then determine the way the screw extrusion molding, determine the scheme design and calculation for each part to after, including the selection and calculation of the motor, spiral transmission part of the design and calculation, design and calculation of screw axis and the secondary gear reducer design calculation and the design of the transmission shaft, bearing selection, through the Proe 3 d software of straw charcoal modeling and dynamic simulation of compression molding machine, using two-dimensional CAD software for overall structure drawing, completed the 2 d part assembly drawing and part drawing.

Key Words: Straw briquette. Screw extrusion; The stress checking; Two-dimensional assembly
