Dust falling device for chemical safety production

The utility model relates to the technical field of chemical safety production, in particular to a dust falling device for chemical safety production, which comprises a base and a water tank, the water tank is fixedly mounted at the upper end of the base, a vertical rod mechanism for assisting dust falling in chemical safety production is arranged on the water tank, and the vertical rod mechanism comprises a first water pipe. A supporting rod is fixedly installed at the circumferential end of the lower section of the first water pipe and fixedly installed at the upper end of the supporting frame, a thread is arranged on the outer side wall of the first water pipe, a rotating block is rotationally installed on the outer side wall of the first water pipe, and a thread groove formed in the rotating block is matched with the thread. A second water pipe is slidably mounted on the inner side wall of the first water pipe. By arranging the four high-pressure spray heads, dust falling can be carried out on air in an a
