Waste heat recovery mechanism of paper machine

The utility model provides a waste heat recovery mechanism of a paper machine, and relates to the technical field of waste heat recovery. The problems that an existing paper machine waste heat recovery mechanism cannot achieve simultaneous recovery of auxiliary water vapor and is low in heating efficiency are solved. Comprising a mounting support part; the mounting support part is fixedly connected with an elastic fitting piece; a fitting heat absorption device is connected to the elastic fitting piece in a sliding manner; an input device is fixedly connected to the attaching heat absorption device. The attaching heat absorption device is fixedly connected with a tight attaching piece. By the adoption of the attaching heat absorption device, attaching waste heat absorption can be conducted on the non-working face of the drying cylinder, the overall structure is simpler, the waste heat recovery efficiency can be effectively improved, meanwhile, the installation arc-shaped plate is arranged, the heating area ca
