Abstract
The utility model discloses a coal pipe dredging device which comprises a moveable dolly, a powder collector bag and a blowing sweeper. The powder collector bag is arranged on the movable dolly and is provided with an end cap at the upper end. The lower end of the end cap is communicated with the powder collector bag and the upper end of the end cap is communicated with a hose through which the end cap is communicated with the blowing sweeper. When the coal pipe is blocked, the blowing sweeper is communicated with a discharge valve and the discharged powder can be collected in the powder collector bag when the discharge valve is opened, thus avoiding pollution to the environment. When the blockage is serious, compressed air can be blown to the coal pipe through the blowing sweeper for reverse blowing and sweeping, and the blocked coal powder can be brought out by the reverse air flow. The whole process is convenient and effective, thus improving work efficiency and reducing maintenance cost.
