文档介绍：摘要
刮泥机主要应用于广泛用于城市污水处理厂及各种工业废水处理工程中,功能是将辐射式沉淀池中沉淀后的污泥刮集和排除,在污水处理设备中起到至关重要的作用,是保证污水处理厂各种沉淀构建物正常运转的关键设备。
刮泥机一般又分为周边传动、中心传动、链条传动等,周边传动刮泥机又分为全跨式和半跨式两种,本设计研究的是半跨式周边传动刮泥机。
在设计的过程中,围绕机械结构系统的要求展开的,通过对比几套方案的优缺点,最后定下了本篇论文的设计方案,本设计选用半跨式周边传动,其中有水平桁架、旋转桁架、板梁、中心旋转支承、刮臂与刮板、轮子与走道、联轴器等结构,该方案较好的设计出了一套刮泥设备,该机械具有结构简单、重量轻,节约运行费用、维护管理方便,消耗功率小,工效高,安全性高,传动平稳,操作方便造价低等优点。

Abstract
Scraping mud-mainly used extensively for urban sewage treatment plants and industrial wastewater treatment projects, function is to be radiation-sedimentation tank precipitation after scraping the mud-and exclude, in sewage treatment equipment to missioner important role is to ensure that the sewage treatment plant all kinds of precipitation Construction of the normal operation of key equipment.
The mud scraper divides into the peripheral transmission, the central transmission, the chain drive generally and so on, the peripheral transmission mud scraper divides into entire straddle type and half straddle type two kinds, what this design research is half straddle type peripheral transmission mud scraper.
In the design process, launches regarding the mechanism system's request, through contrasts several sets of plans the good and bad points, finally has settled this paper design proposal, this design selects half straddle type peripheral transmission, including the horizontal truss, the revolving truss, the plate girder, the central revolving supporting, to blow the arm and the scraper, the wheel and the aisle, shaft coupling isostructuralism, this plan good design set has blown the putty equipment, this machinery has the structure to be simple, the weight is light, saves the operating cost, the maintenance management to be convenient, the consumed power is small, the work efficiency is high, the security is high, the transmission is steady, ease of operation construction cost low status merit.
