Urea particle adding device

The utility model discloses a urea granule adding device relates to denitration device technical field, including discharge space, urea hopper, conveying subassembly and urea plectrum, urea stock bin is used for storing urea granule, and is provided with the discharge port that is used for discharging into the discharge space. The urea stirring piece is driven by the driving device to rotate and arranged in the discharging space, and the urea particles in the discharging space can be stirred to the conveying assembly. The conveying assembly can convey urea particles into the to-be-denitrated device. The conveying amount of urea particles in unit time can be controlled by controlling the rotating speed of the urea shifting piece, the large-range adjustment of the urea adding amount in the to-be-denitrated device is achieved, the urea particles are shifted through rotation of the urea shifting piece so that the urea particles can be conveyed, excessive extrusion cannot be caused to the urea particles, and the d
