文档介绍：摘要
竹纤维是从竹子中提取出来的一种天然纤维材料,竹纤维除了具有天然纤维素纤维的优良特性外,其组织物经特定加工后,具有很高的绿色环保性、良好的透气性、独特的回弹性、瞬间吸水性及较强的纵向和横向强度等,因而受到越来越多行业的重视与利用,广泛用于纺织、建筑等行业。我国竹资源非常的丰富,我们应当对竹纤维这种新材料进行更加全面的研究,对它进行更加充分的开发和利用。
目前我国还没有专用竹纤维的分级筛选设备,采用振动筛分可望解决竹纤维的分级筛选问题。圆振动筛可以很好地解决此类问题,因此本次设计的竹纤维分级筛选设备是仿照圆振动筛,该系列振动筛主要用于煤炭行业中物料分级、脱水、脱泥、脱介等作业。其工作可靠,筛分效率高,但设备自身较重。设计分析论述了设计方案,包括振动筛的分类与特点和设计方案的确定;合理设计振动筛的结构尺寸;进行了激振器的偏心块等设计与计算,包括原始的设计参数,电动机的设计与校核;进行了主要零部件的设计与计算,皮带的设计计算与校核,弹簧的设计计算,轴的强度计算,轴承的选择与计算,然后进行了设备维修、安装、润滑及密封的设计,最后进行了振动筛的环保以及经济分析。

Abstract
Bamboo fiber is bamboo extracted a natural fiber materials, bamboo fiber besides have the excellent characteristics of natural cellulose fiber outside anization, the specific things after processing, has the very high green environmental protection sex, good air permeability, unique recovery, instant water imbibition and strong lateral and longitudinal strength, etc, and is more and more attention and the use of the industry, widely used in textile, construction and other industries. Bamboo resources in China are plentiful, we should be in bamboo fiber this new material for prehensive research, to more fully the development and utilization.
At present, China's didn’t have the exclusive classification of bamboo fiber filter device. Vibration screening using bamboo fiber is expected to solve the problem of classification filter. Circular Vibrating Screen can solve such problems, Therefore the design of the classification of bamboo fiber filter device is modeled on a round shaker ,the series of major shaker in the materials used in the coal industry classification, dehydration, desliming, such as referrals from operations. Its reliable, efficient screening, but their heavy equipment. Design analysis on the design options, including the classification and shaker features and design programmes to be confirmed;To design the structure of vibrating screen size; conduct The eccentric block of the exciter, such as design and calculation, including the original design
