A rotary sludge high-efficiency drying device belongs to the field of sludge drying technology. The invention includes a base, a support seat fixedly installed on the top of the base, and a drying cylinder rotatably mounted inside the support seat. A sludge crushing mechanism is installed inside the drying cylinder. A drive seat is slidably mounted on the top of the base, and a feed cover is fixedly connected to the top of the drive seat. A discharge port is rotatably connected to the side wall of the drying cylinder, which, after being rotated and unlocked, is used to discharge the dried sludge. A cone-shaped nozzle periodically pierces and retracts from the sludge blocks located at the bottom of the drying cylinder. This piercing breaks the hard outer shell of the sludge, creating pores and cracks inside the sludge. High-temperature hot air can directly penetrate into the interior of the sludge blocks through these pores and cracks, significantly increasing the heat transfer contact area, improving the moisture evaporation rate in the initial drying stage, and shortening the residence time of the sludge in the drying cylinder, thereby improving the overall drying capacity and efficiency of the equipment.
