Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Embodiment 1:

[0022] Please refer to Figures 1-4 As shown in the figure, the present embodiment proposes an aluminum rod heating furnace with waste gas recovery device, which comprises a box 1, the upper surface of the box 1 is fixedly connected with an inlet tank 2, one side wall of the inlet tank 2 is fixedly connected with a first transport pipe 3, the upper surface of the box 1 is fixedly connected with a heat pipe waste heat recovery device 4, one side wall of the heat pipe waste heat recovery device 4 is fixedly connected with a second transport pipe 5, one side wall of the box 1 is fixedly connected with a demister tank 6, the front of the box 1 is movably connected with a protective door 7, the inner wall of the box 1 is fixedly connected with a sealing partition 8, the left and right sides of the sealing partition 8 are fixedly connected with mounting brackets 9. Since the sealing partition 8 is adopted, the heat generated by the heating furnace 25 can be blocked, and the demister tank 6 can filter the mist in the waste gas, so that the mist is discharged.

[0023] The left and right sides of one side wall of the mounting bracket 9 are fixedly connected with fixed frames 10, one side wall of the mounting bracket 9 is fixedly connected with a drive motor 11, one side wall of the drive motor 11 is rotatably connected with a rotating shaft 12, the outer wall of the rotating shaft 12 is slidably connected with a cleaning brush 13, the inside of the fixed frame 10 is fixedly connected with an activated carbon adsorption plate 14. Since the cleaning brush 13 is adopted, the activated carbon adsorption plate 14 can be cleaned, so as to avoid the clogging of the activated carbon adsorption plate 14.

[0024] Two pairs of extraction boxes 15 are fixed to the inner wall of the box body 1, and three of the extraction boxes 15 are located inside the sealing partition 8, while the other extraction box 15 is located on the inner wall of the box body 1. A discharge box 16 is fixed to one side wall of the box body 1, and a discharge hole 17 is fixed inside the discharge box 16. Because the extraction box 15 is used, the waste heat in the exhaust gas can be sent back to the heating furnace 25, so that the waste heat can be reused. Moreover, the exhaust gas can be filtered through the activated carbon adsorption plate 14 and discharged from the discharge box 16.

[0025] A connecting frame 18 is fixed to the inner wall of the housing 1. A pair of sliding grooves 19 are provided inside the connecting frame 18. A slider 20 is slidably connected inside the pair of sliding grooves 19. The use of sliding grooves 19 and slider 20 allows the connecting plate 21 to be assembled and disassembled. Because the connecting plate 21 can be assembled and disassembled, the aluminum rod of the heating furnace 25 can be removed by the staff.

[0026] A connecting plate 21 is fixedly connected to the upper surface of the slider 20. Adjusting rods 22 are movably connected to the left and right sides of the upper surface of the connecting plate 21. A top plate 23 is fixedly connected to the upper surface of the adjusting rods 22.

A plug inlet 26 is opened on one side wall of the heating furnace 25. The heat dissipation holes 24 allow the exhaust gas generated by the heating furnace 25 to be discharged.

[0028] In use, the heating furnace 25 is installed by aligning the connecting plate 21 and the slider 20 with the sliding groove 19 inside the connecting frame 18. The adjusting rod 22 can adjust the distance of the top plate 23 to adjust the size of the heating furnace 25. The exhaust gas generated by the heating furnace 25 is sent into the demister 6 by a set of extraction boxes 15. The waste heat is sent from the demister 6 to the heat pipe waste heat recovery unit 4 through the second transport pipe 5, and then from the heat pipe waste heat recovery unit 4 to the discharge box 2 through the first transport pipe 3. Box 2 is fed into box 1, and the exhaust gas will be filtered through activated carbon adsorption plate 14. The drive motor 11 will drive the rotating shaft 12 and cleaning brush 13 to clean the activated carbon adsorption plate 14, thereby preventing the activated carbon adsorption plate 14 from clogging. The filtered waste heat and exhaust gas will be sent back to the heating furnace 25 through three sets of exhaust boxes 15, thereby assisting the combustion of fuel in the heating furnace 25. After multiple cycles, the activated carbon adsorption plate 14 will filter the exhaust gas, so that the exhaust gas is discharged from the discharge box 16 and the discharge hole 17.
