[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 and Figure 2 It is understood that this utility model provides a technical solution: an annealing device for high-strength steel production, including: an annealing furnace body 1, a furnace door 2, a slide rail 3, and a furnace car 4. The furnace door 2 is installed at the front of the annealing furnace body 1. The slide rail 3 is provided on the lower inner side of the annealing furnace body 1. The furnace car 4 is slidably connected to the top of the slide rail 3. A chute 5 is opened inside the furnace car 4. A rack plate 6 is slidably connected inside the chute 5. A heat insulation plate 7 is welded to the top of the rack plate 6. A support seat 8 is welded to the top of the heat insulation plate 7. Limiting blocks 9 are welded to both sides of the heat insulation plate 7. A guide plate 10 is welded to the bottom of the heat insulation plate 7 away from the rack plate 6. A motor 11 is installed inside the furnace car 4. A gear column 12 is connected to the furnace car 4 through a bearing between the output end of the motor 11 and the furnace car 4. A guide groove matching the size of the guide plate 10 is opened inside the furnace car 4. The limiting blocks 9 and the furnace car 4 form a sliding structure. The support seat 8 is T-shaped. The gear column 12 and the rack plate 6 form a meshing structure.

[0025] In practical implementation, the annealing device for high-strength steel production is a specially designed device for annealing high-strength steel. Annealing is an important process in steel production. Because forklifts have difficulty quickly lifting the workpieces from the surface of the furnace car 4, the subsequent annealing efficiency is low. After the workpieces on the furnace car 4 have finished annealing, the furnace car 4 can be moved out of the annealing furnace body 1. At this time, the motor 11 can be started. When the motor 11 rotates forward, it drives the gear column 12 to rotate forward. When the gear column 12 rotates, it meshes with and drives the rack plate 6 to move upward. When the rack plate 6 moves, it slides against the furnace car 4 through the slide groove 5. The process of the rack plate 6 moving... In the middle, the heat insulation plate 7 can be moved. When the heat insulation plate 7 moves, it can move the limiting block 9 and the guide plate 10. When the heat insulation plate 7 moves, it can lift the support base 8 and the workpiece on its surface. When the workpiece rises to the specified height, the motor 11 can be turned off. At this time, the forks on the forklift can be moved to the gap between two adjacent sets of support bases 8, so that the forks on the forklift can move to the bottom of the workpiece through the gap, so that the forklift can quickly lift the workpiece. After the workpiece is removed from the support base 8, the motor 11 can be reversed, so that the support base 8 can be lowered to the specified position, so as to support the workpiece to be annealed later.

[0026] See Figure 1 and Figure 2 It can be seen that the annealed workpiece can be lifted by the support seat 8, so that the forklift can quickly carry it, thereby improving the efficiency of subsequent workpiece annealing.

[0027] See Figure 1 , Figure 2 and Figure 3 It is known that a fan 13 is installed on the top of the annealing furnace body 1, a suction pipe 14 is connected to the bottom of the fan 13, an exhaust pipe 15 is connected to the outside of the fan 13, a fixing block 16 is welded to the top of the annealing furnace body 1 near the exhaust pipe 15, a purification box 17 is set on the outside of the fixing block 16, a ventilation pipe 18 is connected to the outside of the purification box 17, an activated carbon adsorption net 19 is installed inside the purification box 17, a sealing plate 20 is connected to the top of the activated carbon adsorption net 19, a docking plate 21 is connected to the side of the purification box 17 near the fixing block 16, a threaded knob 22 is threadedly connected inside the docking plate 21, a through hole 23 is opened on the side of the purification box 17 near the exhaust pipe 15, the size of the through hole 23 matches the size of the exhaust pipe 15, and a threaded groove is opened inside the fixing block 16.

[0028] In practice, the trolley-type annealing device is a common type of annealing equipment. During the annealing process, the impurities attached to the surface of the workpiece are easily released into the environment after high-temperature treatment, which will pollute and affect the outside air. The fan 13 can be installed on the top of the annealing furnace body 1 and the purification box 17 can be pushed towards the exhaust pipe 15. When the purification box 17 moves, it can drive the ventilation pipe 18 and the docking plate 21 to move. When the docking plate 21 moves to the position above the fixed block 16, the purification box 17 can be close to the outside of the fixed block 16. At the same time, the exhaust pipe 15 can be inserted into the purification box 17 through the through hole 23. At this time, the threaded knob 22 can be tightened so that the end of the threaded knob 22 can slide into the fixed block 16, thereby fixing the position of the purification box 17 and preventing the purification box 17 from shifting or loosening.

[0029] See Figure 1 , Figure 2 and Figure 3 It can be seen that when the harmful gas generated inside the annealing furnace body 1 enters the purification box 17 through the suction pipe 14 and the exhaust pipe 15, the harmful gas can be adsorbed and purified by the activated carbon adsorption net 19. The purified gas can be discharged to the outside through the ventilation pipe 18, so that the discharged gas is not likely to contain harmful substances, thus making the outside air less susceptible to pollution and influence, and at the same time, the staff are less likely to inhale harmful substances.

[0030] In summary, when using this high-strength steel production annealing device, the motor 11 rotates forward, which drives the gear column 12 to rotate forward. When the gear column 12 rotates, it meshes with and drives the rack plate 6 to move upward. When the rack plate 6 moves, it can slide with the furnace car 4 through the slide groove 5. The annealed workpiece can be lifted by the support seat 8, so that the forklift can quickly carry it, thereby improving the annealing efficiency of subsequent workpieces. The activated carbon adsorption net 19 can adsorb and purify harmful gases. The purified gas can be discharged to the outside through the ventilation pipe 18, so that the discharged gas is not likely to contain harmful substances, thus making the outside air less susceptible to pollution and impact. At the same time, workers are less likely to inhale harmful substances. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
