Design and application for an automatic antifreeze fluid sprinkler of railway coal conveyor

The central theme of this paper is to design a two-lane automatic antifreeze fluid sprinkler of railway coal conveyor. The structure, principle and industrial application about this sprinkler are given in detail. By means of the control of PLC, our device realizes the even, automatic, and short-range spraying of antifreeze fluid for five inside surfaces and the coal seam in the train wagon. This equipment, which can efficiently resolve the problem of railway coal conveyor from freezing in winter, shows the advanced technology in the field of coal transportation. Moreover, based on the successful experiments in practice, this equipment will have a broad range of prospect of popularization and application.
