摘要: 东方测控的DFS智能干选机采用干法选煤技术,利用X射线 辨识输送带上的煤和矸石,判断矸石的形状及速度,并开启对应的喷嘴,通过喷吹高压空气来改变矸石移动轨迹,最终实现煤与矸石的分离。DFS智能干选机可以将50-300mm块煤分选,最大型号DFS40-300系列处理能力可达380t/h,可实现无人值守,可代替手选、动筛跳汰机、浅槽分选机等。该文基于TRIZ方法对智能干选机的喷吹机构进行改进,能够更好地提高矸石的分离率。满足现场的生产要求,提高精煤比例,提高煤炭品质,提高经济效益。

Abstract: The DFS intelligent dry separator of Dongfang Measurement & Control adopts dry coal separation technology, uses X-ray to identify the coal and gangue on the conveyor belt, judges the shape and speed of the gangue, and opens the corresponding nozzle, and changes the movement trajectory of the gangue by blowing high-pressure air. , and finally achieve the separation of gangue. DFS intelligent dry separator can separate 50-300mm lump coal, the largest model DFS40-300 series has a processing capacity of up to 380t/h, can be unattended, and can replace manual selection, moving screen jig, and shallow trough sorting machine, etc. In this paper, based on the TRIZ method, the injection mechanism of the intelligent dry separator is improved, which can better improve the separation rate of gangue. Meet the production requirements of the site, increase the proportion of clean coal, improve coal quality, and improve economic benefits.
