Irradiation device for municipal sludge treatment

The utility model relates to the field of sludge treatment, and provides an irradiation device for municipal sludge treatment, which comprises an irradiation chamber, a sludge disc is movably arranged in the irradiation chamber, a plurality of bucket-shaped blanking structures are arranged in the sludge disc, a guide cambered surface is arranged on the periphery of each bucket-shaped blanking structure, and the guide cambered surface is provided with a guide groove. An arc-shaped guide slope body is arranged between every two adjacent hopper-shaped discharging structures, and a discharging opening is formed in the bottom of each hopper-shaped discharging structure; the bottom of the discharge hole is connected with a discharge pipe group; and the discharge pipe group is used for intermittently closing or opening the channel so as to control the irradiation time of the contents in the sludge disc. Through guiding of the guiding cambered surface and the arc-shaped guiding slope body on the sludge disc, sludge i
