树枝粉碎机进料口设计
摘要:树枝粉碎成型机是一个能源与饲料相结合性产业，产业波及效果强，对与其相关的下游产业有明显的带动作用与推动作用。环保部门调研后发现，树枝、木屑等农林废弃物，每年大概有三分之一被废弃，造成了资源浪费。乱堆乱弃或以低效方式直接焚烧这些农林废弃物，还会污染水体，影响村容镇貌和大气环境质量，甚至对交通安全构成威胁。利用秸秆、稻壳、锯末、树枝、木屑等农林废弃物为原料，经粉碎加压增密成型，就成了生物质固体成型燃料。据初步计算，我国一年可收集各类秸秆5000万吨，制成生物燃料后相当于减少3800万吨原煤的使用。环保局有关专家称，生物质固体成型燃料是一种国际公认的清洁能源，具有保护大气环境、减少能源消耗的特点，可替代燃煤应用于各种锅炉。目前，全国已有不少企业的锅炉用上了这种新能源。
利用Pro/E对锤片式粉碎机转子中的进料口进行三维建模、虚拟装配、模型分析。设计者可以充分利用Pro/E单一数据库管理技术，通过改变尺寸参数来方便地修改和更新零件，还可以直观地观察和分析转子的外形、零件间的相互位置关系和运动状态。

Branches shredder feed opening design
Abstract：The branches crush the molding machine is a combination of energy and feed industry, industry spill-over effects, and its related downstream industries a significant role in promoting the role in promoting. Environmental protection department of research and found that tree branches, sawdust and other agricultural and forestry wastes, each year about one-third of abandoned, resulting in a waste of resources. Huddle indiscriminate disposal or incineration of these agricultural and forestry wastes to inefficient, but also pollute the water, the village appearance and quality of atmospheric environment, and even, perform the pose a threat of traffic safety. Straw, rice husk, sawdust, twigs, sawdust and other agricultural and forestry wastes as raw materials, molding, it becomes a smash pressure densification of biomass solid briquette. According to preliminary calculations, the annual collection of straw 50 million tons, representing a decrease of 38 million tons of raw coal use made of bio-fuels. Environmental Protection Agency experts said, the biomass solid briquette is an internationally recognized clean energy, protect the atmospheric environment, reduce energy consumption characteristics of the substitution of coal used in various boilers. The boiler of the present, the country has a lot of companies using this new energy.
Using Pro / E on the feed opening in the hammer mill rotor, three-dimensional modeling, virtual assembly, model analysis. Designers can take full advantage of Pro / E single database management technology, by changing the size parameters to easily modify and update the parts can also be observed visually and analysis of the shape of the rotor, the mutual positional relationship between the parts and the state of motion.
