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.
