Dust collecting device for producing motorized cargo ship

The utility model relates to a dust collecting device for producing a motorized cargo ship, which comprises a dust collecting barrel, a horn opening is arranged on one side of the dust collecting barrel, an exhaust fan is connected to the outer side of the upper end of the dust collecting barrel, and an arc-shaped guide runner communicated with the horn opening is arranged in the dust collecting barrel. A gas-solid separation set and a powder guiding set which are distributed up and down are further arranged in the dust collecting barrel, and powder generated in the production process flows to the horn mouth along with pumping pressure of the exhaust fan and is guided to the gas-solid separation set through the arc-shaped guiding flow channel to be subjected to gas-solid separation. Solid particles in the powder flow into the dust collecting barrel along with guiding of the powder guiding set, and gas in the powder penetrates through the gas-solid separation set to be exhausted outwards under the action of th
