This utility model relates to the technical field of carbonization furnace cooling devices, and discloses a carbonization furnace cooling device with a circulating air duct, including a cooling tank. A chassis is fixedly connected to the bottom of the cooling tank. A motor is fixedly connected to the top right side of the chassis. A turntable is fixedly connected to the output end of the motor. A cylindrical block is fixedly connected to the left side of the turntable. An elongated block is fixedly connected to the left side of the cylindrical block. A rotating shaft is rotatably connected to the top of the elongated block. A connecting plate is rotatably connected to the outer wall of the rotating shaft. In this utility model, the motor drives the turntable to rotate, and then the cylindrical block begins to rotate with the turntable. The elongated block makes a curved motion. Through the rotating shaft, the connecting plate begins to make a linear motion, pushing the guide plate to swing left and right. Therefore, the cooling air volume entering the air duct is controlled to meet the cooling needs of different parts and different working stages of the carbonization furnace.
