摘要

粉粒物料运输车是采用压缩空气使运输的粉粒物料流态化后，通过管道输送到一定距离和高度，用于运输如水泥，面粉，滑石粉，煤粉等的罐式汽车。研究粉料散装运输可以提高运输效率，节约运输费用，降低产品成本，同时能实现装运卸贮机械化。

本课题以气卸散装粉煤灰车为具体研究对象，文中介绍了气卸散装粉煤灰车的发展现状，确定了承载粉煤灰的吨位并对汽车底盘进行选型及总体布置，对其罐体进行设计计算，其中包含流化板、多孔板、罐体支承装置的设计以及对罐体有效容积进行计算。

利用止推板和连接支架对罐体总与二类底盘进行了连接并固定，通过焊接方法保证了罐体和罐体支承座的连接。最后对整车性能进行了分析，应用CAD软件建立整车装配、罐体总成及相关零件模型。

ABSTRACT

The powder tanker of gas unloading take a significant roles in special vehicle. To study and design the powder tanker of gas unloading can improve the level of mechanization of loading and save labor, reduce labor intensity and lower construction costs. So, researching and designing the powder tanker of gas unloading has a very important practical significance in practical.

The cement tanker of gas unloading was as specific subjects in this text. The text expound the cement tanker of gas unloading development of the special vehicle, identified the tonnage of cement which carrying , to the second underpan design the tank, which includes flow of plates, porous panels, tank support and calculate the effective of tank volume.

Thrust plate and connect plank is used to fix the tank with a car, through various means such as welding tank and ensure the tank connection with support saddle. Finally, analysis the vehicle performance , Application of CAD software to establish vehicle assembly, the tank model and related spare parts.

Key Words：Silt material；the second unperpan；Flyash
