Automatic dust removal method and system for cement silo roof

The invention relates to automatic dust removal method and system for a cement silo roof and belongs to the technical field of dust removal for cement silos. The method has advantages of automatic dust removal and energy consumption reduction. The method includes: S101) detecting the individual weight of a single dust removal filter cylinder; S102) determining whether the individual weight exceedsthe individual upper limit value, if true, executing the step S103), or if false, entering the step S105); S103) driving a single dust removal filter cylinder to vibrate for a while; S104) when the vibration of the single dust removal filter cylinder is finished, determining whether the individual weight is lower than a lower limit value, if false, returning to the step S103), or if true, executing the step S105); S105) not driving the vibration of the single dust removal filter cylinder. When single dust removal filter cylinder exceeds specified weight, namely, dust accumulates too much, automatic vibration is achie
