Container powder filling system

The invention belongs to the technical field of container powder bulk, and particularly relates to a container powder filling system which comprises a bulk stock bin, the bulk stock bin is connected with a charging pipeline, a discharging opening in the tail end of the charging pipeline is provided with a lifting sealing plate, and the shape and the size of the lifting sealing plate are matched with those of an opening of a container. A dust collection port at one end of a truck loading dust collection pipeline is positioned on the lifting sealing plate, and the other end of the truck loading dust collection pipeline is connected with a bag type dust collector; a container overturning machine is arranged below the lifting sealing plate, and the lifting sealing plate can be in butt joint with a container opening which is overturned to be vertical after descending. According to the system, dust pollution can be completely prevented in the whole loading process, and the phenomena of powder scattering and dust ra
