Furthermore, it drives the deflection blades of the adapter rod to change their angle, optimizing the airflow distribution and achieving intelligent adjustment.

[0025] 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.
[0026] Reference Figure 1-3An embodiment of this utility model provides: a calcining furnace airflow uniformity optimization device with adjustable damper, including a calcining furnace 1, a combustion heater 2 fixedly connected to the bottom of the inner wall of the calcining furnace 1, an exhaust port 3 fixedly connected to the top of the calcining furnace 1 and passing through it, a fan housing 4 fixedly connected to the right end of the calcining furnace 1, a controller installed on the outer wall of the front end of the fan housing 4, a wind direction plate 10 connected to the inner wall of the left end of the fan housing 4 through a wind direction group, the wind direction group including a fixed frame 7 fixedly connected to the inner wall of the left end of the fan housing 4, the outer wall of the wind direction plate 10 rotatably connected to the inner wall of the fixed frame 7, an electric hydraulic cylinder 8 fixedly connected to the front end of the inner wall of the fan housing 4, a sliding plate 9 fixedly connected to the drive end of the electric hydraulic cylinder 8, a plurality of mating grooves 13 opened on the outer wall of the sliding plate 9, a transition plate 11 fixedly connected to the right end of the wind direction plate 10, a mating wheel 12 fixedly connected to the front end of the transition plate 11, and the outer wall of the mating wheel 12 sleeved on the inner wall of the mating groove 13;
[0027] Specifically, in the calcining furnace airflow uniformity optimization device with adjustable damper, when the electric hydraulic cylinder 8 is activated, it drives the sliding plate 9 to move up and down. The sliding plate 9, through the mating groove 13 on it, drives the mating wheel 12 to move synchronously. The movement of the mating wheel 12 further pulls the air direction plate 10 to rotate at the fixed frame 7, thereby achieving precise adjustment of the opening and closing angle of the air direction plate 10. This adjustment mechanism allows the air direction plate 10 to flexibly change its opening and closing angle according to actual needs, thereby effectively adjusting the wind force and direction generated by the blade 22. Through this dynamic adjustment, the device can ensure that the airflow is evenly distributed in the calcining furnace 1, avoiding local overheating or under-burning, and significantly improving the thermal efficiency and calcination quality of the calcining furnace. In addition, the optimization device also monitors and adjusts the angle of the air direction plate 10 in real time through an intelligent control system to adapt to different working conditions, further reducing energy consumption and extending the service life of the equipment, providing a reliable guarantee for the stability and efficiency of the calcination process.
[0028] Reference Figure 4 and Figure 5A fixed shell 6 is fixedly connected to the right end of the inner wall of the fan casing 4. A filter screen 5 is fixedly connected to the right end of the inner wall of the fixed shell 6. A drive motor 15 is fixedly connected to the left end of the filter screen 5. A fixed plate 14 is fixedly connected to the left end of the inner wall of the fixed shell 6. The drive end of the drive motor 15 is connected to blades 22 through an airflow assembly. The airflow assembly includes a drive rod 17 fixedly connected to the drive end of the drive motor 15. A transfer plate 20 is fixedly connected to the left end of the drive rod 17. The blades 22 are rotatably connected to the four sides of the outer wall of the transfer plate 20 at opposite ends. A connecting shell 16 is fixedly connected to the left end of the fixed plate 14. Electric hydraulic cylinders 21 are fixedly connected to both the upper and lower ends of the inner wall of the connecting shell 16. A support ring 18 is fixedly connected to the drive end of the electric hydraulic cylinder 21. A transition ring 24 is rotatably connected to the left end of the support ring 18. A transition rod 19 is rotatably connected to the four sides of the outer wall of the left end of the transition ring 24. A transition block 23 is rotatably connected to the left end of the transition rod 19. The inner wall of the transition block 23 is fixedly connected to the outer wall of the blades 22.
[0029] Specifically: In the calcining furnace airflow uniformity optimization device with adjustable damper, when the material to be calcined is placed in the calcining furnace 1 and the combustion heater 2 is started, the drive motor 15 starts working, driving the drive rod 17 to rotate. The drive rod 17 drives the blades 22 connected to its outer side to rotate synchronously through the transfer plate 20, thereby generating wind force under the rotation of the blades 22, blowing the air filtered at the drive motor 15 into the calcining furnace 1 and discharging it through the exhaust port 3. At the same time, by controlling the electric hydraulic cylinder 21 to pull the support ring 18 to move within the connecting shell 16, the movement of the support ring 18 drives the transfer ring 2. 4. The traction adapter rod 19 causes the adapter rod 19 to push the blade 22 to deflect through the adapter block 23, thereby changing the angle of the blade 22 relative to the transfer plate 20. This flexible adjustment of the angle can not only improve the wind force generated by the blade 22, but also optimize the distribution and direction of the wind force, ensuring that the airflow in the calcining furnace 1 is more uniform and efficient. Through the real-time adjustment of the blade 22 angle by the intelligent control system, the device can dynamically adjust the wind force according to different working conditions, further improving calcination efficiency, reducing energy consumption, and extending the service life of the equipment, providing comprehensive technical support for the stability and energy saving of the calcination process.
[0030] Working principle: When the material to be calcined is placed in the calcination furnace 1 and the combustion heater 2 is in place, the drive motor 15 is started to drive the drive rod 17 to rotate. This causes the drive rod 17 to drive the blades 22 connected to its outer side to rotate through the transfer plate 20. The rotation of the blades 22 generates wind power, which blows the air filtered by the drive motor 15 into the calcination furnace 1 and out through the exhaust port 3. When the electric hydraulic cylinder 21 is controlled to pull the support ring 18 to move, the support ring 18 moves in the connecting shell 16 and causes the adapter ring 24 to pull the adapter rod 19 to move. This causes the adapter rod 19 to drive the blades 22 to deflect through the adapter block 23, changing the angle of the blades 22 relative to the transfer plate 20. This allows the wind power to be increased by changing the angle of the blades 22, thus optimizing the wind power generated by the blades 22.
[0031] When the electric hydraulic cylinder 8 is activated to drive the slide plate 9 to rise and fall, the slide plate 9 moves the engagement wheel 12 through the engagement groove 13. The engagement wheel 12 pulls the wind vane 10 to rotate at the fixed frame 7, so that the opening and closing angle of the wind vane 10 is changed at the fixed frame 7. This allows for adjustment of the wind force and direction generated by the blade 22 by changing the opening and closing angle of the wind vane 10, so that the airflow is evenly distributed in the calcining furnace 1, thereby improving the calcining efficiency of the calcining furnace.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
