龙滩电站高速供料线系统F皮带机优化设计

Optimization of F Belt Conveyer for the High-speed Conveying Line System in Longtan Power Station

龙滩大坝混凝土运输供料线系统由拌和楼出料皮带机和系统连接皮带机、三条高速皮带机供料线、三条负压溜槽和两台塔式布料机组成。混凝土运输供料线是大坝混凝土浇筑的关键设备,每条供料线的平均输送能力为330m3/h,其输送能力为目前水电工程之最。本文主要阐述了高速皮带机3号线F皮带布料机的优化设计及使用情况,并对其特点进行了比较全面的介绍。经优化设计的供料线系统投入使用后,运行情况良好,为龙滩大坝高强度的混凝土浇筑作出了重要贡献。

The concrete delivery system for the dam is corn-posed of mixer feeding conveyer,system connecting conveyer, 3 high-speed belt conveyer lines, 3 vacuum-chutes and 2 sets of tower crane placers. As the key component of concrete pouring for the dam,the concrete delivery system boasts the largest delivery capacity in hydropower projects with an average delivery capacity of 300m^3/h per line. This paper, by taking into account the optimized design for F belt conveyer of the No.3 high-speed belt conveyer lines, and recommend its using, characteristic. The optimized system has been working well ever since it was put into operation,which has contributed a lot to the intense concrete pouring of the darn for Longtan hydropower project.
