The sealing door panel 3 and the smoke filtration box 1 form a rotating structure through the rotating shaft 2, and the extrusion block 5 is symmetrically arranged with respect to the central axis of the sealing door panel 3. The bump 4 is elastically arranged, and the bump 4 is snap-fitted with the smoke filtration box 1 through the limiting hole 6. The activated carbon filter element plate 9 and the smoke filtration box 1 form a sliding structure through the second limiting plate 8, and the fiber fabric filter element plate 10 and the smoke filtration box 1 form a sliding structure through the first limiting plate 7. The activated carbon filter element plate 9 and the fiber fabric filter element plate 10 are arranged in parallel, and the exhaust fan 11 and the fiber fabric filter element plate 10 are arranged in parallel, which can facilitate the regular disassembly and replacement of the activated carbon filter element plate 9 and the fiber fabric filter element plate 10, thereby improving the quality of smoke filtration treatment.

[0023] Please refer to Figures 1-4 , a smoke treatment device for intermediate frequency electric furnaces, the bottom of the smoke filtration box 1 is fixedly connected with an intake pipe 12, a thread groove 13 is opened inside the intake pipe 12, a thread ring 14 is installed inside the intake pipe 12, the bottom of the thread ring 14 is fixedly connected with an air collecting hood 15, the thread ring 14 is threadedly connected with the intake pipe 12 through the thread groove 13, and the air collecting hood 15 is umbrella-shaped, which can facilitate the stable inhalation of the smoke discharged from the intermediate frequency electric furnace.

[0024] Working principle: When in use, by pulling the sealing door panel 3, the limiting hole 6 can extrude the convex block 4, driving the convex block 4 to deform and release the limit on the sealing door panel 3. Under the action of the rotating shaft 2, the sealing door panel 3 flips along the smoke filtering box 1, and at the same time, the extrusion blocks 5 release the extrusion on the activated carbon filter plate 9 and the fiber fabric filter plate 10 respectively.
