Abstract
A feeding machine used for a novel pulverized coal boiler comprises motors, speed reducers, a spiral feeding mechanism, a lifting mechanism, a discharge mechanism and a machine base. Mechanical automatic feeding is achieved, the feeding machine is not affected by moisture of pulverized coal, operation resistance is small, stability is high, and safety and reliability are achieved. By means of a spiral feeding compression air hole, the fluidization action is eliminated when the moisture content of the pulverized coal is higher than 8%. The feeding machine can run at negative pressure through air inflow of a breathing cap, so that the pulverized coal is discharged more smoothly. Rotary material lifting and feeding are adopted, the problem that in the prior art, discharging is not uniform and unstable is solved, and meanwhile the problem that vulcanization and detonation phenomena happen during combustion of the boiler is solved.
