Intermittent dust removal system for finished product surge bunkers

The invention relates to an intermittent dust removal system for finished product surge bunkers. The intermittent dust removal system is characterized in that bag-type dust removers are arranged on the top of a discharge funnel of a movable reversible belt conveyor or a movable discharge mine car, automatic sealed guide boxes are arranged on the tops of the finished product surge bunkers, each automatic sealed guide box comprises a box, a grate plate, a herringbone guide plate and adjusting devices, each grate plate is arranged on the top of the corresponding box, each herringbone guide plate is arranged at the bottom of the corresponding box, the corresponding adjusting devices are respectively arranged on two side surfaces of each box, each adjusting device comprises upper guide rings, lower guide rings, threaded rods, slide gaskets, springs and nuts, the upper guide rings and the lower guide rings of the adjusting devices of each automatic sealed guide box are symmetrically arranged on the side surfaces of the box, the threaded rods respectively penetrate the upper guide rings and the lower guide rings, the lower portions of the threaded rods are connected with the herringbone guide plates, the slide gaskets are arranged on the threaded rods, the springs sleeve the threaded rods, one end of each spring is connected with the corresponding slide gasket, the other end of each spring is connected with a lower annular guide sheet, and the nuts sleeve the threaded rods and are butted to the slide gaskets. The intermittent dust removal system has the advantages of novel structure, simplicity and convenience in operation and maintenance, good dust removal effect and low capital investment.
