摘要
排泥机械是在自来水厂和污水处理厂中配合沉淀池使用的,它是重要的排泥专用设备。排泥机械的形式随工艺的条件与池形的结构而有所不同,目前常用的排泥机械可分为平流式(矩形)沉淀池排泥机和辐流式(圆形)排泥机两大类。刮泥机主要有周边传动式、中心传动式、矩形平流池桁车式、链传动式等。它是排泥机械中的一种常见设备,它是沉淀池不可缺少的设备。一般采用铝合金,不锈钢或防腐处理型钢制作,具有电动提肥,过载保护、撇渣、刮泥、虹吸排泥过程监控,电气联锁等特点,动力消耗低、防腐性能强、吸泥量可调、传动平稳、运行可靠。
本设计研究的刮泥机为周边传动式。并将可编程序控制器(PLC)应用于控制系统中,极大的简化操作过程,提高运行稳定性。具有结构简单,运转连续,管理方便等一系列优点。

Abstract
Arranges the putty machinery is in the Waterworks and the Sewage treatment plant,the coordinate sedimentation pond use,it is the important special purpose equipment. Arranges the putty machinery's form differs from along with the craft condition and the pond structure,at present monly used platoon putty machinery may divide into the advection type (rectangle) a sedimentation pond row of putty machine and the spoke class type (circular) the row of putty machine two broad headings. The mud scraper mainly has peripheral transmission type,central transmission type,the rectangular advection pond clothes rack car type,the chain drive type and so on. It is in the row of putty machinery's one kind mon equipment; it is the sedimentation pond essential equipment. Generally uses the aluminum alloy, the stainless steel or the antiseptic treatment section manufacture,has raises electrically operated fat, the over-load protection, casts aside the dregs,to blow the putty,the rainbow to attract the row of putty process monitoring,characteristics and so on electrical interconnection, the power consumption is low,the antiseptic property strong,attracts the putty quantity adjustable,the transmission to be steady,the movement is reliable.
This design research mud scraper for peripheral transmission type. And applies programmable controller (PLC) in the control system,the enormous simplification operating process,enhances the movement the structure to be simple,the revolution is continual,manages the convenience and so on a series of merits.
