[0040] During use, the worm 8 is driven by the driving motor 7 to rotate, and then the worm wheel 9 engaged with the worm 8 drives the connecting frame 6 fixed on the top of the central rotating shaft 5 to rotate, and then the connecting frame 6 drives the turntable 10 to rotate, so that all the aluminum alloy plates 20 can make a circular motion around the center point of the turntable 10 in the annealing furnace body 1;

[0041] The guide assembly includes an annular guide rail 12 provided on the top of the support base 4 and four guide shafts 11 welded sequentially to the outer wall of the bottom of the connecting frame 6. The outer walls of the four guide shafts 11 are slidably connected to the inner wall of the annular guide rail 12 to ensure the stability of the turntable 10 during rotation.

[0042] The mounting groove 14 is formed at the top of the placement plate 13, and the butterfly-shaped bidirectional screw 15 is rotatably mounted in the mounting groove 14. Two L-shaped connecting rods 16 are symmetrically screwed onto the two opposite threaded ends of the butterfly-shaped bidirectional screw 15, and the outer walls of the two L-shaped connecting rods 16 are slidably connected to the inner wall of the mounting groove 14.

[0043] Among them, two positioning clamping rods 17 are welded to the outer walls of the opposite ends of the two L-shaped connecting rods 16 in sequence, and the transmission shaft 18 is concentrically welded to the bottom outer wall of the placement plate 13.

[0046] Example 2, reference Figure 2 and Figure 8-9 This embodiment is optimized based on the embodiment 1, specifically: an aluminum alloy plate annealing device, further comprising a flue gas cooling and purification mechanism

[0047] The flue gas cooling and purification mechanism includes a fixed plate 23, a water cooling box 24, a refrigerator 25, a serpentine condenser 26, a purification box 27, a filter screen 1 28, a filter screen 29, a filter screen 30, an activated carbon filter screen 31 and a sealing cover plate 32;

[0048] Among them, the fixing plate 23 is welded to the outer wall of one side of the annealing furnace body 1, the water cooling box 24 is fixed to the top outer wall of the fixing plate 23, the refrigerator 25 is fixedly installed in the water cooling box 24, and the serpentine condenser 26 is provided in the water cooling box 24. The refrigerator 25 is convenient for cooling the water cooling liquid in the water cooling box 24 to ensure the water cooling effect;

[0049] Among them, the top of the serpentine condenser tube 26 is sealed and fixedly connected to the upper part of one side of the water cooling box 24, and the top of the serpentine condenser tube 26 is communicated with the smoke exhaust port of the annealing furnace body 1. The top of the water cooling box 24 is provided with a water injection pipe to facilitate the injection of water cooling liquid into the water cooling box 24. Then, during the annealing process, the high-temperature flue gas generated in the annealing furnace enters the serpentine condenser tube 26 and is fully cooled by the water cooling liquid in the water cooling box 24, thereby preventing the air temperature of the surrounding environment from rising sharply.

[0050] The purification box 27 is fixed to the side wall of the water cooling box 24, and the sealing cover 32 is fixed to the front outer wall of the purification box 27 by bolts. The bottom end of the serpentine condenser tube 26 is sealed and fixedly connected to the lower part of the other side of the water cooling box 24, and the bottom end of the serpentine condenser tube 26 is connected to the bottom of the purification box 27 through a connecting pipe.

[0051] Among them, filter screen 1 28, filter screen 29, filter screen 30 and activated carbon filter screen 31 are inserted into the purification box 27 from bottom to top. The filter pore sizes of filter screen 1 28, filter screen 29 and filter screen 30 decrease from bottom to top. The top of the purification box 27 is provided with evenly distributed smoke exhaust holes 33, which makes it easy to fully filter the cooled flue gas and avoid it from causing serious pollution to the surrounding air.

[0052] The use process of the present invention is:

[0053] First, by rotating the butterfly-shaped bidirectional screw 15, the two L-shaped connecting rods 16 are aligned and brought closer together, and then the two positioning clamping rods 17 are aligned and brought closer together to position and clamp the aluminum alloy plate 20. According to this operation method, all aluminum alloy plates 20 are positioned and clamped on each placement tray 13 to prevent them from shaking and falling during the annealing process.

[0054] Secondly, the two electric slides 2 control the support base 4 fixed on the top of the two slides 3 to automatically move into the annealing furnace body 1, and then the furnace door 34 is automatically closed by the simultaneous contraction of the output shafts of the two electric push rods 35, so that the annealing process can begin;

[0055] Subsequently, the worm 8 is driven to rotate by the driving motor 7, and then the worm gear 9 engaged with the worm 8 drives the connecting frame 6 fixed on the top of the central rotating shaft 5 to rotate, and then the connecting frame 6 drives the turntable 10 to rotate, so that all the aluminum alloy plates 20 can make a circular motion around the center point of the turntable 10 in the annealing furnace body 1, and the large gear 22 is controlled by the control motor 21 to rotate, and then all the small gears 19 engaged with the large gear 22 will also rotate, and the rotation of the small gear 19 will drive the placement disk 13 fixed on the top of the transmission shaft 18 to rotate, which can make all the aluminum alloy plates 20 make a circular motion around the center point of the placement disk 13 in the annealing furnace body 1. In this way, it can ensure that all the aluminum alloy plates 20 are heated evenly in the annealing furnace body 1, avoiding the situation where the overall quality of the aluminum alloy plates is deteriorated due to uneven local heating;

[0056] Finally, during the annealing process, the high-temperature flue gas generated in the annealing furnace enters the serpentine condenser 26 and will be fully cooled by the water-cooling liquid in the water-cooling box 24, thereby avoiding a sharp increase in the air temperature of the surrounding environment. The water-cooled flue gas will enter the purification box 27 and will be filtered layer by layer by filter screen 1 28, filter screen 29, filter screen 30 and activated carbon filter screen 31 in sequence, and finally discharged to the external environment from the evenly distributed smoke exhaust holes 33 to avoid serious pollution to the air in the surrounding environment.

[0057] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
