DETAILED DESCRIPTION

[0018] As Figures 1-6The application discloses a multi-layer electric heating air drying oven, which comprises a drying cabinet 1, three partitions 3, air holes 4 and rotating shafts 5. The drying cabinet 1 is a cuboid shell structure, and cabinet doors 2 are respectively connected to the left and right sides of the front wall of the drying cabinet 1. The inner wall of the drying cabinet 1 is fixedly connected with the three partitions 3, and the three partitions 3 divide the drying cabinet 1 into a chamber I 19, a chamber II 20 and a chamber III 21. The lowermost partition 3 has a gap with the inner bottom wall of the drying cabinet 1, and the three partitions 3 are arranged in parallel. The partition 3 is provided with uniformly distributed air holes 4. The two ends of the two rotating shafts 5 are respectively rotatably connected to the inner top wall and the inner bottom wall of the drying cabinet 1. The inner top wall and the inner bottom wall of the drying cabinet 1 are rotatably connected with the two rotating shafts 5 through bearings I 6. The two rotating shafts 5 are symmetrically distributed, and the outer walls of the two rotating shafts 5 are fixedly connected with three rotating discs 7. The rotating discs 7 are arranged at equal intervals in the vertical direction, and are rotatably connected with the three partitions 3 through bearings II 8. The rotating discs 7 are embedded in the partitions 3. The rear side of the drying cabinet 1 is provided with a hot air blower 9. The outlet end of the hot air blower 9 is fixedly connected with a air supply pipe 10. The air supply pipe 10 extends upwards, and the outer wall of the air supply pipe 10 is fixedly connected with three branch pipes 11. The three branch pipes 11 are respectively connected with the chamber I 19, the chamber II 20 and the chamber III 21, and are fixedly connected with the rear wall of the drying cabinet 1. The right wall of the drying cabinet 1 is fixedly connected with three exhaust pipes 12. The three exhaust pipes 12 are respectively connected with the chamber I 19, the chamber II 20 and the chamber III 21. The inner wall of each exhaust pipe 12 is provided with an exhaust fan 13.
