【正文】 心控制水泥回轉(zhuǎn)窯系統(tǒng)，主要包括有: ①回轉(zhuǎn)窯輔助電機的正常運轉(zhuǎn)控制。③燃燒器移動小車的正反轉(zhuǎn)運行控制。⑤擋輪液壓站TE326的控制。②輔助電機、燃燒小車的控制比較簡單，直接用繼電接觸器控制其運行。 關(guān)鍵詞 水泥，回轉(zhuǎn)窯，PLC，控制系統(tǒng)ABSTRACTIn building materials,metallurgy,chemical,mineral processing,environmental protection,and many other industries,people widespread use of rotating cylindrical device on the bulk or slurry material to do physical or chemical treatment,whichh is known as rotary kiln that with rotating cylinder device.Cement production is posed by the raw material pretreatment (homogenizing,crushing,drying,etc.),raw material preparationing redients,grinding,homogenization),clinker calcination(deposition and preheating,calcination,coal mill),cement products (Cement batching,grinding,packaging).And calcining cement clinker which is the most important cement production process,so its equipment–cement rotary kiln,often referred to as the heart of kiln consist of mechanical,electrical,hydraulic and other studying and the design of cement rotary kiln system we will use PLC as the main core of the including: Firstly, rotary control of the normal operation of auxiliary , the main motor of the variable frequency , move the car reversing the burner operation control. The fourth is the main reducer lubrication station control stations shall TE525 lubrication pressure,temperature,liquid level control. The fifth is gear wheel hydraulic TE326 control. Conclusions control program include: First of all, main motor for frequency conversion motor,which inverter control its speed ,auxiliary motors,bustion car’s control is relatively simple,which direct contacts with the relay control its operation. Last but not least,because of gear wheel hydraulic station,the main gearbox lubrication station’s control contents and more plex process,both adopted by the PLC control method,the use of PLC bination of hardware and software to achieve gear wheel hydraulic station,the main gearbox lubrication Stop the normal operation and fault alarm control functions.Key words Cement,Kiln,PLC,Control System目 錄摘 要 ..............................................................................................................................IABSTRACT .....................................................................................................................II1 緒論 .............................................................................................................................1 水泥生產(chǎn)工藝...........................................................................................................1 水泥熟料的煅燒 ................................................................................................2 回轉(zhuǎn)窯的發(fā)展 ...................................................................................................2 回轉(zhuǎn)窯的性能和特征 .........................................................................................3 水泥回轉(zhuǎn)窯硬件系統(tǒng)技術(shù)參數(shù) ..................................................................................32 總體方案設(shè)計 .............................................................................................................4 設(shè)計任務(wù)要求...........................................................................................................4 電氣控制方案...........................................................................................................63 水泥窯控 制方式 .........................................................................................................9 操作方式..................................................................................................................9 DCS 介紹 ...........................................................................................................9 操作方式設(shè)計 ...................................................................................................9 與外界的連鎖信號 ..................................................................................................10 配電系統(tǒng) ................................................................................................................114 硬件電路設(shè)計 ............................................................................................................13 輔助電機的控制 .....................................................................................................13 燃燒小車的控制 .....................................................................................................13 PLC 硬件配置 ..........................................................................................................13 PLC 基本知識 ..................................................................................................13 PLC 機型選擇 ..................................................................................................15 模塊連線圖 ............................................................................................................17 PLC 輸入輸出端子設(shè)計 ............................................................................................18 功能梯形圖設(shè)計 .....................................................................................................20 閃爍信號的產(chǎn)生 ..............................................................................................20 主減速機潤滑站起動及抗干擾措施 ..................................................................21 主減速機潤滑站冷卻水的投入和關(guān)閉...............................................................21 潤滑站綜合起停 ..............................................................................................22 主減速機潤滑站油泵電機的工作......................................................................22 主減速機潤滑站加熱器的運行 .........................................................................23 擋輪液壓站的正常工作....................................................................................23 擋輪站加熱器的工作 .......................................................................................25 聲光報警程序..................................................................................................26 設(shè)計小結(jié) ................................................................................................................265 控制電路設(shè)計 ............................................................................................................28 I/O 表設(shè)計 .................................................................................
