Abstract

This work presents the experimental characterization of a novel industrial bulk solids feeder, named Batchpump, and aims to validate the performance in terms of transport capacity and compressed gas consumption of an unconventional compact pressure vessel, used as a feeding device for dense phase pneumatic conveying. Experimental test data was collected for limestone as the conveyed material. The developed device was shown to have similar performance parameters (transport rate and gas consumption) when compared to conventional versions of blow tanks operating at 4 bar pressure and conveying powder material at about 9 t/h rate, albeit the smaller dimensions and simplification in operation, resulting in significative advantages in retrofits and in the implement a new conveyor line.

摘要

这项工作展示了一种名为 Batchpump 的新型工业散装固体给料器的实验表征，旨在验证非常规紧凑型压力容器在输送能力和压缩气体消耗方面的性能，用作密相气力输送的给料装置。收集了石灰石作为输送材料的实验测试数据。与在 4 bar 压力下运行并以约 9 t/h 的速率输送粉末材料的传统版本的吹气罐相比，开发的设备具有相似的性能参数（输送速率和气体消耗量），尽管尺寸更小且操作更简单，从而在改造和实施新的输送线方面产生显着优势。
