氣流輸送系統(tǒng)設(shè)計(jì)
摘要：氣流輸送技術(shù)是一項(xiàng)綜合技術(shù)，涉及流體力學(xué)、材料力學(xué)、自動(dòng)化技術(shù)、制造技術(shù)等領(lǐng)域，屬高新技術(shù)項(xiàng)目。氣流輸送的應(yīng)用已有100多年的歷史，早在1853年郵局就用來輸送信件，1883 年港口用于裝卸糧食，到20 世紀(jì)初開始用于工業(yè)生產(chǎn)。近年來，隨著生產(chǎn)發(fā)展和生產(chǎn)過程日趨自動(dòng)化，對節(jié)約能源和環(huán)境保護(hù)的要求越來越高，氣流輸送技術(shù)憑借自身的技術(shù)特點(diǎn)得到了迅速發(fā)展和應(yīng)用。在不斷地探索和創(chuàng)新過程中，氣流輸送的對象從早期的谷物，面粉和信件迅速擴(kuò)展到水泥，砂料，化工原料，煤粉等物料。應(yīng)用的范圍遍及糧食，港口，化工，冶金，電力，鑄造，食品，醫(yī)藥等領(lǐng)域。輸送方式從原始到如今完善，合理，從稀相懸浮輸送到濃相濃度的栓流輸送，初步解決了氣流輸送能耗高，管道磨損及物料破碎等問題，提高了氣流輸送技術(shù)的可靠性和經(jīng)濟(jì)性。
本文通過對原始材料的分析，采用了吸送式氣流輸送。吸送式氣流輸送裝置在氣流輸送技術(shù)中是一種較早發(fā)展起來的輸送方式，目前在世界上使用十分廣泛，這是因?yàn)樗司哂袕V泛適應(yīng)條件外還有許多突出的優(yōu)點(diǎn)：生產(chǎn)率高，結(jié)構(gòu)簡單緊湊，操作靈活方便易實(shí)現(xiàn)自動(dòng)化等。
根據(jù)其原始材料，計(jì)算其輸料管內(nèi)徑，確定輸送風(fēng)速及其風(fēng)量，同時(shí)要計(jì)算系統(tǒng)中各項(xiàng)的壓力損失。在這些都確定的情況下，根據(jù)上述分析計(jì)算結(jié)果選定適合的風(fēng)機(jī)及其配備電動(dòng)機(jī)，確定確實(shí)合理的管道布置方式，最后得出整套輸送裝置。

Pneumatic Conveying System
Abstract: Pneumatic Conveying technology is a comprehensive technical, involving fluid dynamics, mechanics of materials, automation technology, manufacturing technology and other fields,which belongs to a high-tech projects. The application of Pneumatic Conveying has been more than 100 years of history, back in 1853, the post office had used it to deliver correspondence;in 1883 the port for loading and unloading of foodstuffs, to the beginning of the 20th century for industrial production.In recent years, with the development of production and the production process automation, energy conservation and environmental protection in an increasingly high demand., pneumatic conveying technology, by virtue of its technical characteristics have enjoyed rapid development and application. In the process of exploring and innovation constantly, the object of pneumatic conveying changes from the early cereals, flour and letters to the rapid expansion of cement, sand and industrial chemicals, coaldust and other materials. Application areas include of food, ports chemical engineering, metallurgy, power, casting, food, medicine and other fields; Transportation mode perfects from the original to the present perfection, reasonable, from dilute phase suspension transported to Ph indicator bolt flow conveying of dense phase, preliminarily settling of the problem of pneumatic conveying of high energy consumption,pipeline of high wear and tear and materials broken, which improve the reliability of the technology and economy of the pneumatic conveying.
Based on the analysis of the original material, this thesis adopts the use of suction sent pneumatic conveyor. Suction sent pneumatic conveyor installations is a development for the early delivery in the gas-delivery technology; Now to be used in a very wide range in the world, it is in that in addition to its extensive adaptation conditions, there are still many outstanding advantages : high productivity, simple and compact structure, flexible and user-friendly operation to achieve automation.
Baed on its original material, the writer has to calculate internal diameter of the conveying pipe, determine wind speed and wind transport volume, also has to calculate the various system pressure loss. In the case of these being identified, the writer ,according to the above analysis and computing results , is to selected the suitable Fan and its equip motor, determine the exact piping layout in a reasonable way, and get the final package delivery devices.
