【正文】 帶式輸送機 是一種摩擦驅動以連續(xù)方式運輸 物料 的機械。主要適應于移動較強的工程，如 年產(chǎn) 60 萬方混凝土攪拌站設計 5 道路、橋梁等建設項目。在一些經(jīng)濟發(fā)達的國家商品混凝土用量占全部混凝土用量的比例也非常高，如：美國： 84%；瑞典：83%；澳大利亞： 68%；荷蘭： 56%。根據(jù)國外預拌混凝土行業(yè)生產(chǎn)實踐表明，采用預拌混凝土進行施工，一般可以提高勞動生產(chǎn)率 50%200%，節(jié)約原材料 10%15%，降低勞動成本 20%左右。以后，水泥與混凝土的生產(chǎn)技術迅速發(fā)展，混凝土的用量急劇增加，使用的范圍日益擴大，至今，它已經(jīng)成為世界使用量最多的人造材料。發(fā)展綠色混凝土是我們行業(yè)的基本方針。日本和亞洲 “四小龍 ”在進入這一階段后國民生產(chǎn)總值年均增長率長期保持在 10 %左右的水平，一般都持續(xù)了 17年到 20年。早在 80年代，建設部有關部門高瞻遠矚。法國人皮埃爾 1927年德國的弗利茨 用聚合物改進水泥混凝土的性能也是一種行之有效的途徑。 1926年《世界技術》雜志介紹了一種新的建筑材料 —多孔混凝土，文章指出：多孔混凝土由丹麥人雅各布森 (Jacobsen)教授發(fā)明，并由兩位工程師：菲利普森 ( Philipsen)和拜爾(Beyer)推向市場，其建造費用比普通混凝土減少 50%，建造時間明顯縮短。 混凝土在中世紀仍得到應用，但不及古羅馬時期。 關鍵詞： 攪拌站；混凝土；設計 The Design of the Concrete Mixing Station with an Annual 年產(chǎn) 60 萬方混凝土攪拌站設計 II output of 600,000 Cubic Meters Major： XXXXXXX Student： XXXXX Supervisor： XXXXXXX Abstract The mixing station is the annual output of 600,000 m3 concrete mixing station, which consists of mixing console, material weighing system, material handling systems, material storage systems and control systems and other five major system ponents and other ancillary facilities. Is a modern concrete building for the main machinery. It not only saves production time, but also improves the production and marketing rate. The mixing station uses two stage production process, there are two production lines, mixing uniform quality and high productivity. For dry, rigid, semirigid, plastic and various proportions of concrete mixing effect. Mixing console mixing shaft with antiblocking technology to effectively prevent caking of cement on the shaft, shaft seal uses a unique multiseal structure, effectively prevent leakage and ensure that the entire mixing mortar system last long run. All of the powder materials, from the material, ingredients, measuring, mixing of the materials are fed in a closed state where, fully enclosed and the main conveyor belt mixing structure greatly reduces the dust and pollution of the environment throat sound. Dust and vacuum using special fiber cloth, so that the dust generated when feeding into the dust pletely without to spread around, and collected dust can be easily recycled, effective protection of the environment. Complete equipment maintenance and repair overhaul parts of a platform or ladder for easy inspection and maintenance operation, the host has a pump stroke and manual cleaning operations two devices. Building site structure and aggregate belt conveyor fully enclosed structure, to ensure that all operations can be carried out regardless of the weather. Using closedform belt conveyor, the lower part of overflow outlet, can effectively prevent and debris scattered everywhere. The whole machine adopts puter control, automatic control can also be operated manually, easy operation. Office of the State control system uses a unique dual control dual form, the control unit and data sharing between management unit, control unit failure can be converted to the management machine work, to ensure maximum continuous system uptime. Located in the Deyang City Taishan Road and Qianjiang Road Interchange southeast corner diagonally opposite the Bus Station, covers an area of 10000 m2. The main contents include 年產(chǎn) 60 萬方混凝土攪拌站設計 III domestic and concrete mixing station developments and trends in the development of concrete products, the total graphic design, mix design, aggregate field design, the choice of batching machine, belt conveyor, mixing design, process, construction factory conditions, civil cases, environmental protection, laboratory and office design and staffing for mixing and economic analysis. General graphic design seeks to meet normal production conditions, reduced footprint and reduce costs. Aggregate farm covers an area of 3600 m2. Stacker full three meters, to meet the mixing station six days the amount of sand and gravel.
