工程技術研究型 □ 軟件開發(fā) □理論研究 （請在對應類型前面打√） 一、課題簡介（課題含義、課題來源、需要解決的問題、已知條件）： 課題含義：將O－Sepa型選粉機精確分級的原理結合旋風式選粉機的旋風 筒的收集功能以及通過式選粉機的粗粉分離功能而組成的新型組合式選粉機,能 處理較大量的含塵氣體，系統(tǒng)中料路、氣路合一，使整個系統(tǒng)更簡單, 特別是在 烘干粉磨系統(tǒng)和風掃磨系統(tǒng)中,可省去為處理大量含塵氣體而建立的粗粉分離 器系統(tǒng)，其優(yōu)越性能更加顯著。選粉機自帶低阻高效旋風收塵器，可將80％的 合格成品收集下來，減輕了下一級收塵器的處理壓力和工作負荷，使系統(tǒng)的運 轉率更高，投資更省，并且，產(chǎn)品細度調(diào)節(jié)范圍廣，控制簡單，改變細度不停 機。 課題來源：根據(jù)選粉機當前國內(nèi)外發(fā)展情況以及企業(yè)實際需求，而確定該 課題。 需要解決的問題：如何將三種選粉機優(yōu)點有機的結合在一起。 已知條件：1、分級粉體 2、風量：3000m3/min 3、產(chǎn)量：120~200t/h 4、電機功率：100~300kw 二、本課題國內(nèi)外發(fā)展概況： 圈流粉磨的廣泛應用,促進了選粉機的發(fā)展。從選粉機的性能方面看,可將其分為三代產(chǎn)品。 第一代——普通撒料式空氣選粉機 這種選粉機是以給柯(Gayco)型和斯特蒂文特(Sturtevant)型為代表。它們均為空氣在機內(nèi)循環(huán),利用物料顆粒的離心力和重力不同進行分級的,所以有人把它們稱為內(nèi)部循環(huán)式的離心式選粉機。 　 第二代——旋風式選粉機 60年代初,西德維達格(Wedag)公司為解決第一代空氣在內(nèi)部循環(huán)的空氣選粉機存在的問題,首先發(fā)明了帶多個小旋風筒的空氣動態(tài)選粉機,其典型代表就是普通的旋風式選粉機。這種選粉機的特點是空氣在機內(nèi)外循環(huán) 。 第三代——高效選粉機 1979年日本小野田公司開發(fā)了O－SEPA選粉機，不僅保留了旋風選式粉機外循環(huán)的優(yōu)點，而且采用籠型轉子平面螺旋氣流選粉原理，從而大幅度提高了選粉效率。以它為代表的籠式選粉機稱為高效選粉機，也被稱為第三代選粉機。 由于O－SEPA型選粉機優(yōu)點突出，一些著名的水泥設備制造公司紛紛參照其工作原理，竟相開發(fā)了各自的第三代選粉機，如丹麥（F.L.Smidth）公司開發(fā)的Sepax型高效選粉機；洪保（KHD）公司開發(fā)的SKH型和ZUB型型高效選粉機等等。這些選粉機的工作原理與O－SEPA型選粉機相同，但結構上各有特點。 目前國內(nèi)大多數(shù)的水泥生產(chǎn)廠家所用的選粉分級系統(tǒng)為離心選粉機、旋風式選粉機，而新建的水泥生廠線以配用第三代高效選粉機為主。 附參考文獻： 1 葉達森．粉碎與制成．北京：中國建筑工業(yè)出版社，1992 2 吳一善．粉碎學概論．武漢：武漢工業(yè)大學出版社，1993 3 許林發(fā)．建材機械工程手冊．武漢：武漢工業(yè)大學出版社，2000.7

（—）總體設計概述：新型組合式選粉機是籠式高效選粉機和粗粉分離器以及旋風收塵器的緊湊組合, 主體可分為上下兩部分，上部為籠式高效選粉機，為分級核心；下部相當于粗粉分離器，用于初步處理含塵氣體。主體外圍均布多個旋風收塵器，用于收集成品細粉?？蓪⑵錁嬙爝M一步細劃為：分級核心鼠籠；安裝在選粉室外部的可調(diào)導風葉及固定它們的殼體部分；收集粗粉的下部灰斗；收集細粉的管道、旋風筒；主軸和驅(qū)動主軸旋轉的傳動裝置；總體原理為：從磨機來的高濃度含塵空氣由下部風管進入選粉機，經(jīng)內(nèi)錐體整流后沿外錐體與內(nèi)錐體之間的環(huán)形通道減速上升，其中的粗粉經(jīng)重力沉降后沿外錐體邊壁滑入粗粉收料筒實現(xiàn)重力分選，重力分選后的空氣在導風葉的導流和轉子的旋轉作用下，在導風葉和轉子之間形成穩(wěn)定的水平渦流選粉區(qū)。粉磨后的物料從選粉機進料口喂入，其分選原理與O-SEPA選粉機相同。只是分選后細小輕微的顆粒隨氣流被吸入內(nèi)部流經(jīng)配風室分四路進入旋風收塵器，大部分成品細粉被分離出來，收塵后的空氣從旋風收塵器上的排風管排出，進入下一級收塵設備。粗重顆粒則下落經(jīng)內(nèi)錐體匯集到粗粉收料筒，返回磨機再磨。

The characteristics of these methods andtheir organic connection between them and put forward to achieve the computerproduct design direction.Key words: Mechanical Product Design MethodDevelopment Trends Design documents will be Semantic Web as a design tool inthe design of its Semantic Web activity of the development of ASK, using nodes andlines to describe the design a network, nodes that components of the cell (such asdesign tasks, functions, components or processing equipment, etc. ), used to adjust thelines and definitions between nodes of different semantic relations, thus the designprocess all the activities and results of pre-built models so that the definition of theearly design requirements to the specific description of each structure can be definedby the relationship between the expression, achieved a computer-aided design process,the leap from the abstract to the concrete.Asystematic design methodThe main features of a systematic design method are: the design as designed by anumber of elements of a system, the independence of each design elements, eachelement of an organic link between the existence of, and is layered, with all the designelements , you can design systems to achieve the required task.Systematic design idea in the 70s by the German scholar Professor Pahl andBeitz, the system based on the theory they developed a general pattern of the design,advocacy design work should have organized. German Engineers Association, on thebasis of this design concept to develop a standard VDI2221 technology systems andproduct development design methods.1.The user needs functional characteristics as a product concept, structuredesign and part design, process planning, job control, etc. based on the macro fromthe product development process of starting the use of quality function deploymentmethod and system to user demand information reasonably and efficiently convertedto the various stages of product development, technical goals and operational controlprocedures method.2.The level of the product life of the organism as a system, and means ofliving systems theory, the product design process can be divided into successfulhierarchy of needs to achieve the functional requirements of the conceptual level andproduct level of the specific design. At the same time life-support systems used toexpress the abstract icons of the product functional requirements, system structureformation of product features.3.The mechanical design of the application of systems science into two basicquestions: First, to be designed as a system dealing with the products, the best way todetermine its component parts (modules) and their mutual relations1; is the productdesign process as a system, according to design objectives, a correct and reasonablydetermine the various aspects of the design work and various design stage.Because each designers point of research questions and to consider the questionof emphasis, to design a specific research methods used is also different. Here aresome representative of the systematic design methods.4.Design Element MethodWith the five design elements (functions, effects, effects vector, shape, elements,and surface parameters) describe the product solutions that a product to determinethe value of the five design elements, the product of all the features and characteristicsof the value of i.e. determined. Scholars in China have adopted similar methodsdesigned to describe the products original understanding.5.Graphic modeling methodAnd developed a design analysis and guidance systems KALEIT, with thelevel of clear graphic description of a products functional structure and its associatedabstract information, to the system structure and function relationship of graphicalmodeling, and functional connection between the layers 2.Assistance will be designed to be divided into two aspects of methodology andexchange of information using the Nijssen Information Analysis Method can be usedgraphic symbols, with a rich semantic model structure, can be described as integrationconditions, can be divided into types of constraints can be achieved in relationsbetween any combination of characteristics , the design method to solve integrationand information technology to realize the design process of information betweendifferent abstraction layers between the graphical modeling.6.Concept - Design methodProducts design is divided into concept and design in two stages. Conceptphase of the task is to find, choose and mix to meet the requirements of the originalunderstanding of design tasks. Design stage of work is a concrete realization of theoriginal understanding of the conceptual stage.Of the programs idea of specific described as: In accordance with theappropriate functional structure, seeking to meet the design requirements of theoriginal understanding of the task. The functional structure of the sub-function isperformed by the structural elements to achieve, and structural elements of thephysical connection between the definition of a feature vector, feature vector andstructural elements further the interaction between the formation of the functionaldiagram ( mechanical diagram). The program design is based on functional diagram,the first qualitative description of all of the feature vector and structural elements,and then quantitatively describe all the structural elements and the connection parts( feature vectors), the shape and location to be structure diagram3. Roper, H. usinggraph theory, by means of which he defines as the total design unit (GE), structuralelements (KE), functional structural elements (FKE), connect structural elements(VKE), Structural Parts (KT), structure element part (KET) concepts, as well asdescribe the structure element size, location, and transmission parameters of theinteractions between a number of kinds of schematics, the intuitive designprofessionals have done a formal design method a description of the formation of aneffective application of existing knowledge, methods, and applied to ideas anddesign stage.7.Bond Graph MethodFunction of the composition of system components will be divided into produceenergy, consumed energy, changing energy forms, such as various types of energytransfer, and to use bond graphs to express the function component solution, hoping tofunction-based model and bond graph combine to achieve functional structure theautomatic generation and functional structure with the bond graph automaticconversion between the search for bond graph generated by a number of designmethods.To promote the product on the basis of functional analysis, the product has somefeatures broken down into one or several modular basic structure, by selection andcombination of the basic structure of these modular form into different products.These basic structures can be parts, components, or even a system.The structure should have a standardized interface (connection and co-operationdepartment),andisserialized,universal,integrated,hierarchical,agile,economic-oriented, with interchangeability, compatibility and relevance. Chinascombination of software component technology and CAD technology, variant designcombined with the modular design, according to modular principle of classification,will be divided into descending Machining Center Machine Tool product level,component level, component level and component level, and use expert knowledgeand CAD technology to combine them into different species, different specificationsof functional blocks, and then by the combination of these functions into differentmodules of the overall program processing center.To design a directory as an alternative variation of the mechanical structure ofthe tool, the solution proposed by the design elements of a complete, structured layout,the formation of the solution set design catalogs. And in the solution set designed tocomment on each one listed in the directory solution additional information, is verybeneficial to design engineers select solution elements.The vigorous development of network technology, collaborative design andmanufacturing, as well as the product from the users functional requirements design processing assembly finished product of this realization of concurrentengineering possible. However, an important prerequisite to achieve these goals oneof the conditions is to realize the effect of product design three-dimensionalvisualization. To this end, three-dimensional graphics software, more and moreintelligent design software programs used in the product design, virtual realitytechnology and multimedia, hypermedia tools for product design is also its first debut.At present, Germany and other developed countries are focused on researchhypermedia technology, product data exchange standard STEP, as well as standardvirtual reality modeling language based on a standard exchange format for virtualenvironments) in the product design applications.Mechanical product design is moving in computer-aided realization of intelligentdesign and to meet the needs of distributed collaborative design and manufacture ofdirection, due to the computer product design Study on the implementation startedlate, not yet mature, to achieve the above objectives program design tools4. Authorbelieves that the integrated use of paper, four types of design method is an effectiveway to achieve this goal. Although the integrated use of these methods are moreinvolved in the field, not only with the mechanical design of the field-relatedknowledge, but also to the systems engineering theory, artificial intelligence theory,computer hardware and software engineering, network technology areas such asdomain knowledge, it is still product design must be working for. Abroad in researchin this area has achieved initial success, our scholars have been aware of CAD designtechnology and the importance of international exchange and cooperation, and itsmeasures to be taken.Feature-based design methodology of knowledge The main features are: using acomputer can identify the language to describe the characteristics of the product andits design experts in the field of knowledge and experience to establish the appropriateknowledge base and inference engine, re-use of stored domain knowledge and theestablishment of the inference mechanism to bring computer-aided product design.The mechanical system design is mainly based on the characteristics of a product,and design experts in the field of knowledge and experience to push volume anddecision-making, the completion of body type, the number of synthesis. To achievethis stage of computer-aided design, must study the automatic acquisition ofknowledge, expression, integration, coordination, management and use. To this end,the design and scholars at home and abroad program for the mechanical systemdesign knowledge of the automated processing done a lot of research work, theapproach can be summarized into the following several.
