Waste heat recycling device for charcoal production

The invention discloses a waste heat recycling device for charcoal production. The device comprises a waste heat recycling box, a hot air input pipe and a cold air output pipe are symmetrically arranged at the two ends of the waste heat recycling box, one end of each first heat conduction fin penetrates through the inner wall of the waste heat recycling box and extends into a heating boiler mechanism, a plurality of second heat conduction fins which are evenly and vertically arranged at equal intervals are connected to the inner wall of one side, close to a drying box mechanism, of the waste heat recycling box in an inserted mode, and the first heat conduction fins and the second heat conduction fins are horizontally arranged in a staggered mode. Through the first heat conduction fins and the second heat conduction fins which are horizontally arranged on the two sides of the inner wall of the waste heat recycling box in a staggered mode, heat can be fully utilized, the first heat conduction fins transfer heat
