Sludge carbonizing machine

The utility model relates to the technical field of sludge treatment, in particular to a sludge carbonization machine, and solves the problem that heat energy is wasted as heat of the outer wall of a carbonization cylinder is discharged into air without being utilized in the prior art. A sludge carbonizing machine comprises two bearing plates fixed to the ground, a carbonizing cylinder is fixedly connected to the bearing plate at the right end through a connecting plate, a first conveying mechanism used for carbonizing sludge is arranged in the carbonizing cylinder, a drying cylinder is arranged on the outer side of the carbonizing cylinder, an arc-shaped plate is fixedly connected to the bearing plate at the right end through an L-shaped rod, and the arc-shaped plate is fixedly connected to the bearing plate at the right end through an L-shaped rod. The drying cylinder is rotationally connected with the arc-shaped plate, and a second conveying mechanism for drying the sludge is arranged in the drying cylinde
