OuYe furnace drying device

The invention discloses an OuYe furnace drying device. The drying device comprises a thermocouple, induced air pipes, an air mixing pipe and gas eduction pipes. The air mixing pipe is vertically arranged. The thermocouple is mounted in the air mixing pipe. The induced air pipes are uniformly connected to the upper end of the air mixing pipe at intervals in central symmetry. A horizontal flow guide plate is horizontally arranged at the lower end of the air mixing pipe. Flow guide grooves are uniformly distributed in the bottom face of the flow guide plate at intervals in central symmetry. A big octagonal coiled pipe and a small octagonal coiled pipe are arranged in the top face of the horizontal flow guide plate from inside to outside in a spaced mode and communicate with each other. The pipe wall of the big octagonal coiled pipe and the pipe wall of the small octagonal coiled pipe are each provided with four rows of holes horizontally from top to bottom. Every two adjacent rows of the holes are spaced by 60-1
