Embodiment Construction
[0039] Taking the typical trolley-type sintering machine in China as an example, the present invention is described:
[0040] Detection of the present invention and hardware system see figure 1. The sintering mobile trolley contains the mixed raw materials being burned, and the lower part of the trolley is the fan system for extracting air to meet the combustion needs, mainly including sintering bellows, sintering flue and main exhaust fan. Since the trolley is spliced by a number of mobile independent trolleys, there are gaps and movable connections between the trolley and the trolley workshop, the bellows and the trolley workshop, which makes it easy to generate air leakage in various parts, and it is difficult to use effective means. Leak detection. The invention proposes to realize the online calculation of the air leakage rate by means of sound collection in the sintering workshop. As shown in the figure, several sound signal collectors are installed in the workshop ...
