[0026] Specifically, the angle iron bracket 1 is used to connect the damper barrel 4 and the electric actuator 2, the actuator connector 3 is used to control the hydraulic cylinder 6, the fixed column 7 is used to drive the first rotating column 9 to rotate, the first rotating column 9 is used to drive the fan blades 11 to rotate, the second rotating column 12 and the first rotating column 9 are used to fix the fan blades 11 to rotate to prevent the fan blades 11 from falling during rotation.

[0027] Reference Figure 2-Figure 3 The outer wall of the fixed shell 10 is fixedly connected to the inner wall of the outer shell 5. A mounting ring 14 is provided on the upper surface of the angle iron bracket 1. The top of the mounting ring 14 is slidably connected to the second fixing ring 15. The inner wall of the second fixing ring 15 is threadedly connected to a threaded rod 16. The top of the threaded rod 16 is fixedly connected to a rotating block 17. The inner wall of the threaded rod 16 is fixedly connected to a buckle 18.

[0028] Specifically, the fixed shell 10 is used to rotate the first rotating column 9 on its inner wall to prevent the first rotating column 9 from being displaced during the rotation process. The mounting ring 14 is used to connect the angle iron bracket 1, and the rotating block 17 is used to drive the threaded rod 16 to rotate.

[0029] Reference Figure 4-Figure 5 The outer wall of the second fixing ring 15 is slidably connected to a mounting block 19, and the outer wall of the mounting block 19 is fixedly connected to the upper inner wall of the electric actuator 2. The inner wall of the mounting block 19 is provided with a sliding groove 20, and the inner wall of the mounting block 19 is provided with a fixing groove 21. The outer wall of the buckle 18 is arranged on the inner wall of the sliding groove 20, and the outer wall of the buckle 18 is arranged on the inner wall of the fixing groove 21;

[0030] Specifically, the mounting block 19 is used to slide on the outer wall of the second fixing ring 15, so that the buckle 18 can be slidably connected to the inner wall of the sliding groove 20. At the same time, rotating the mounting block 19 can make the buckle 18 be stuck to the inner wall of the fixing groove 21 to prevent it from being stuck loosely.

[0031] Working principle: When the device is needed, the pot-type calciner is detected by the electric actuator 2, thereby controlling the hydraulic cylinder 6 to push. When the hydraulic cylinder 6 pushes, it will drive the fixed column 7 to slide. When the fixed column 7 slides, it will drive the fixed rod 8 to slide. At the same time, the fixed rod 8 will push the next fixed column 7 to slide. Similarly, when the fixed column 7 slides, it will drive the first rotating column 9 fixedly connected to its upper surface to rotate. The first rotating column 9 will rotate on the inner wall of the fixed shell 10. When the first rotating column 9 rotates, it will drive the fan The blade 11 rotates. When the fan blade 11 rotates, it will drive the second rotating column 12 to rotate, and the second rotating column 12 will rotate on the inner wall of the first fixed ring 13, and finally the fan blade 11 will rotate, so as to achieve accurate control of the amount of air entering the furnace, thereby optimizing the ratio of combustion air and fuel, achieving more complete combustion, and reducing the emission of unburned fuel and harmful gases. When it is necessary to fix the electric actuator 2, first slide the mounting block 19 to the outer wall of the second fixed ring 15, slide the buckle 18 on the inner wall of the sliding groove 20, and then manually rotate the actuator 2. The movable block 17, when the rotating block 17 rotates, it will drive the threaded rod 16 to rotate, and when the threaded rod 16 rotates, it will drive the buckle 18 on its inner wall to rotate, and when the buckle 18 rotates, it will be stuck to the inner wall of the fixed groove 21. When the electric actuator 2 needs to be released, the rotating block 17 is rotated and pressed. When the rotating block 17 rotates, it will drive the threaded rod 16 to rotate, and when the threaded rod 16 rotates, it will drive the buckle 18 on its inner wall to rotate, and when the buckle 18 rotates, it will slide to the inner wall of the sliding groove 20, and finally the mounting block 1 can be taken out. 9. Thus, the electric actuator 2 can be quickly disassembled and replaced without large-scale disassembly or shutdown of the entire damper system, thereby reducing maintenance time and downtime costs. The easily adjustable damper structure of the tank-type calcining furnace can not only accurately control the amount of air entering the furnace, thereby optimizing the ratio of combustion air to fuel, achieving more complete combustion, and reducing unburned fuel and harmful gas emissions, but also can quickly disassemble and replace the electric actuator 2 without large-scale disassembly or shutdown of the entire damper system, thereby reducing maintenance time and downtime costs.
