【正文】 出料、控制等系統(tǒng)及結(jié)構(gòu)部件組成,用于生產(chǎn)混凝土的成套設(shè)備。常用于混凝土工程量大、施工周期長、施工地點集中的大中型工程。本章主要介紹了混凝土的用途、歷史、種類和發(fā)展前景以及混凝土的機械等項目背景。經(jīng)過科研院所和生產(chǎn)企業(yè)的共同開發(fā),適時引進國外先進的混凝土泵和混凝土攪拌輸送車技術(shù),使我國在商品混凝土機械的設(shè)計、制造能力和水平都有了很大提高,一些產(chǎn)品已有批量生產(chǎn),其技術(shù)水平與當今世界水平同步,減少了進口,節(jié)約了外匯,取得了較好的經(jīng)濟效益和社會效益。產(chǎn)品技術(shù)標準和預(yù)拌混凝土標準的要求中,對于混凝土攪拌站(樓)的技術(shù)指標己達到發(fā)達國家水平。目前,德國、美國、意大利、日本等國家的攪拌站在技術(shù)水平和可靠性方面處于領(lǐng)先地位。在施工建設(shè)中,如混凝土路面,絕大多數(shù)構(gòu)件都是鋼筋混凝土構(gòu)件,如建筑物的基礎(chǔ)、梁、柱、板、橋梁等。按混凝土拌合物的和易性分有:干硬性混凝土、半干硬性混凝土、塑性混凝土、流動性混凝土、高流動性混凝土、流態(tài)混凝土等。是用陶粒、浮石、碎磚、礦渣等作為集料配制成的。大孔混凝土(普通大孔混凝土、輕骨料大孔混凝土),其組成中無細集料。輕集料包括浮石、火山渣、陶粒、膨脹珍珠巖、膨脹礦渣、礦渣等。集料為砂、石。重混凝土是表觀密度大于2500kg/m179。許多中小城市也在推廣應(yīng)用商品混凝土。集中攪拌的商品混凝土主要用于現(xiàn)澆混凝土工程,混凝土從攪拌、運輸?shù)綕补嘈?~2h,有時超過2h。實踐證明,現(xiàn)代混凝土配合比全計算法設(shè)計為此提供了簡單快捷和可靠的技術(shù)途徑。 現(xiàn)代混凝土的發(fā)展方向——商品混凝土。現(xiàn)代測試技術(shù)也越來越地應(yīng)用于混凝土材料學的研究。自19世紀20年代出現(xiàn)了波特蘭水泥后,由于用它配制成的混凝土具有工程所需要的強度和耐久性,而且原料易得,造價較低,特別是能耗較低,因而用途極為廣泛。1895年—1900年,法國用鋼筋混凝土建成了第一批橋梁和人行道。僅幾年后,他在巴黎建造公寓大樓時采用了經(jīng)過改善迄今仍普遍使用的鋼筋混凝土主柱,橫梁和樓板。這些特點使其使用范圍十分廣泛,不僅在各種土木工程中使用,就是造船業(yè)、機械工業(yè)、海洋的開發(fā)、地熱工程等,混凝土也是重要的材料。, mixing station consists of mixing console, weighing system, material conveying systems, material storage system and a control system posed of 5 major systems and other ancillary facilities. In order to meet the demand of annual party, the mixing station to select JS3000 type double horizontal shaft forced mixer. Standalone operation and PLD series batching machine for concrete mixing station of the dual advantages of the preparation of JS3000 concrete mixer, can also provide supporting host for the mixing station, can the mixing of dry concrete, plastic concrete, fluidity concrete, lightweight aggregate concrete and mortar, applicable to all kinds of big, in, small. Factory and highway, bridge, water conservancy, wharf and other large industrial and civil construction engineering. Is the main machinery for modern concrete buildings. It not only saves the production time, but also greatly improve the rate of production and marketing. The mixing station with single order production process, has a production line, uniform mixing quality, high productivity.In order to ensure the mixing station to the normal, efficient production, maintenance and repair parts of the platform is provided with a set of equipment maintenance or ladder, convenient examination and repair operation, host cleaning with pump and manual operation of two sets of devices. The platform floor type structure and aggregate belt conveyor fully enclosed structure, ensure all operations can be regardless of the weather. Using closed belt machine form, the lower part is provided with a discharge outlet, can effectively prevent and sand scattered everywhere. The machine adopts puter control, can automatically control, and manual operation, the operation is simple and convenient. Control system adopts the one and only state the dual control mode, control and management of data sharing among, machine failure control can be converted to work management machine, the maximum guarantee for the normal operation of the system.Keywords: reinforced concrete,concrete mixing station,design目 錄第一章結(jié)論 7 7 7 7 7 7 8 9 9 10第二章混凝土攪拌站術(shù)語與概念 11 11 11 12 14 15 16第三章攪拌站機械設(shè)計與配置的技術(shù)條件 17 17 17 17 20 21 21 22 22 23 23 25 26第四章年產(chǎn)45萬方攪拌站建設(shè)說明 27 27 27 27 28 29 29 29 30 31 31 33 35 35第五章混凝土攪拌站的使用要點和操作規(guī)程 37 37 37 37 37 38第六章日常維護和保養(yǎng) 39 39 39 39 39 40 40 40 40 41 41 41第七章混凝土攪拌站的常見故障與解決方法 42 42(氣缸)故障 42 43 43 43第八章結(jié)論 45參考文獻 46致謝 47第一章緒論年產(chǎn)45萬方攪拌站初步設(shè)計 混凝土的用途混凝土是當代最主要的土木工程材料之一。采用封閉形式的皮帶機,下部設(shè)有溢料出口,能有效防止及沙石四處散落。它不但節(jié)約了生產(chǎn)時間,而且大大提高了生產(chǎn)銷率。攪拌站主要由攪拌主機、物料稱量系統(tǒng)、物料輸送系統(tǒng)、物料貯存系統(tǒng)和控制系統(tǒng)等5大系統(tǒng)和其他附屬設(shè)施組成。年產(chǎn)45萬方混凝土攪拌站畢業(yè)設(shè)計專業(yè):材料工程技術(shù)學生: 指導老師: 摘 要混凝土攪拌站是隨著水泥的誕生而產(chǎn)生和發(fā)展的。本商品混凝土攪拌站的年產(chǎn)量為45萬m179。是用于現(xiàn)代化混凝土建筑的主要機械。站臺樓式結(jié)構(gòu)及骨料皮帶輸送機全封閉結(jié)構(gòu),保證了所有作業(yè)都可風雨無阻地進行。關(guān)鍵詞:混凝土;混凝土攪拌站;設(shè)計;With an annual output of 450000 m3 concrete mixing station of graduation designProfessional: Material Engineering TechnologyStudent: Instructor: AbstractConcrete mixing station is produced with the birth and development of cement. It is a necessary equipment for engineering construction, bridges, roads, dams and other construction, which consists of storage materials, proportioning, feeding mechanism ponents, is a plex system affected by many factors restrict the. With the highspeed development of China economy, the prehensive national strength has been enhanced, the state investing on the basis of design and construction of the increase, stimulating the rapid development of city mercial concrete, at the same time, the concrete mixing stations have larger development space, the initial mixing station appears to be just a single machine, concrete mixing their own, with largescale infrastructure construction development, the mercial concrete mixing station big market, the demand is more and more big, measurement of increasingly high demand, then the station mixing various forms with metering device, stirring from the modern concrete station.The mercial concrete mixing station for the annual 450000 m 179。同時混凝土地具有抗壓強度高、耐久性好、強度等級范圍寬等特點。1879年,他開始制造鋼筋混凝土樓板,以后發(fā)展為整套建筑使用由鋼筋箍和縱向桿加固的混凝土結(jié)構(gòu)梁。1887年德國工程師科倫首先發(fā)表了鋼筋混凝土的計算方法;英國人威爾森申請了鋼筋混凝土板專利;美國人海厄特對混凝土橫梁進行了實驗?;炷量梢宰匪莸焦爬系哪甏渌玫哪z凝材料為粘土、石灰、石膏、火山灰等。60年代以來,廣泛應(yīng)用減水劑,并出現(xiàn)了高效減水劑和相應(yīng)的流態(tài)混凝土;高分子材料進入混凝土材料領(lǐng)域,出現(xiàn)了聚合物混凝土;多種纖維被用于分散配筋的纖維混凝土。利用現(xiàn)代新技術(shù),大力發(fā)展新工藝、新設(shè)備;廣泛利用工業(yè)廢渣作原材料等,都是今后需要不斷解決的課題。為了使商品混凝土性能穩(wěn)定、經(jīng)濟、性價比高,必須嚴格選擇所需的原材料和優(yōu)化混凝土的配合比。因此,商品混凝土是現(xiàn)代混凝土與現(xiàn)代化施工工藝的結(jié)合,它的普及程度能代表一個國家或地區(qū)的混凝土施工水平和現(xiàn)代化程度。在我國許多大城市,如北京、上海、天津、廣州、深圳等,商品混凝土攪拌站都在一百個以上,其規(guī)模和工藝水平不亞于發(fā)達國家。這三種混凝土不同之處就是骨料的不同。普通混凝土即是我們在建筑中常用的混凝土,表觀密度為1950~2500kg/m179。它又可以分為三類:輕集料混凝土,其表觀密度在800~1950kg/m179。加氣混凝土是由水泥、水與發(fā)氣劑制成的。輕骨料大孔混凝土的表觀密度為500~1500kg/m179。按配筋方式分有:素(即無筋)混凝土、鋼筋混凝土、鋼絲網(wǎng)水泥、纖維混凝土、預(yù)應(yīng)力混凝土等?;炷翙C械廣泛應(yīng)用于公路、鐵
