Silkworm chrysalis drying device using waste heat of boiler

The invention discloses a silkworm chrysalis drying device using waste heat of a boiler. The device comprises a waste heat recovery box, a dust falling box, an air inlet cover and an air outlet cover,the dust falling box is arranged at the bottom of the waste heat recovery box, an air inlet cover and an air outlet cover are welded to the top of the waste heat recovery box, air inlet pipes and airoutlet pipes are fixedly inserted into the waste heat recovery box, the top ends of the air inlet pipes extend into the air inlet cover, and the bottom ends of the air inlet pipes extend into the dust falling box. According to the silkworm chrysalis drying device, flue gas generated by work of the boiler can be led into the air inlet cover under effect of a draught fan, the flue gas sequentiallypasses through the air inlet pipes, the air outlet pipes, and first and second guide pipes and is then discharged into a silkworm chrysalis drying box, silkworm chrysalis is dried, boiler waste heat is used, and heat energy is
