[0028] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] The preferred embodiment of the rotary kiln for producing active metallurgical lime provided by the present invention is as follows: Figures 1 to 5As shown: A rotary kiln for the production of active metallurgical lime, comprising a base 5, an adjusting component 7 is provided on one side of the interior of the base 5, a mounting plate 4 is rotatably connected to one side of the top of the base 5, a charging box 2 is fixedly connected to one side of the top of the mounting plate 4, a vibration anti-blocking component 3 is provided on one side of the bottom end of the charging box 2, a charging pipe 15 is fixedly connected to the upper end of one side of the charging box 2, an exhaust gas exhaust pipe 1 is fixedly connected to the top of the charging box 2, a kiln body 14 is rotatably connected to one side of the mounting plate 4, a large gear 13 is fixedly connected to the middle position of the surface of the kiln body 14, a fixing frame 8 is fixedly connected to one side of the fixing frame 8, a driving motor 10 is fixedly connected to one side of the fixing frame 8, and the output end of the driving motor 10 extends to the interior of the fixing frame 8 and is fixedly connected to a small gear 12 meshing with the large gear 13 through a coupling.

[0031] The cam 305 of the first embodiment is fixed on the cam 306 of the second embodiment, and the cam 306 of the second embodiment is fixed on the cam 306 of the second embodiment.

[0032] In this embodiment, the rubber blocks 303 are evenly spaced on the top of the sliding plate 301 and are fixedly connected to the top of the sliding plate 301 by bolts. Fixing the evenly spaced rubber blocks 303 with bolts facilitates disassembly and replacement of damaged rubber blocks 303.

[0033] In this embodiment, the cross-section of the fixed block 304 is arc-shaped, and the fixed block 304 and the cam 305 are both in the same vertical plane. The arc-shaped fixed block 304 in the same vertical plane as the cam 305 facilitates its rotational contact with the cam 305 to drive the sliding plate 301 to slide.

[0034] In this embodiment, a sliding structure is formed between the movable block 307 and the surface of the slide rod 306. The top of the movable block 307 is fixedly connected to one end of the fixed spring 308. The sliding between the movable block 307 and the slide rod 306 makes the sliding plate 301 slide back and forth more smoothly.

[0035] In this embodiment, the cross-section of the loading box 2 is a right-angled trapezoid, and the bottom end of the loading box 2 is inclined at an angle of thirty degrees to the horizontal direction. By using the inclined loading box 2, the active metallurgical lime inside the loading box 2 can be more smoothly discharged into the kiln body 14 for loading.

[0036] Example 2

[0037] On the basis of Example 1, the preferred embodiment of the rotary kiln for producing active metallurgical lime provided by the present invention is as follows Figures 1 to 5 As shown: the adjustment component 7 includes a fixing groove 701, which is opened at the top of the base 5, and a servo motor 702 is fixedly connected to the upper end of one side of the base 5. The output end of the servo motor 702 extends to the inside of the fixing groove 701 and is fixedly connected to a threaded rod 707 through a coupling. The surface of the threaded rod 707 is wrapped with a threaded plate 706, and the top of the threaded plate 706 is hinged with a connecting rod 703 at equal intervals. The top of the connecting rod 703 is hinged to one side of the bottom end of the mounting plate 4. By starting the servo motor 702 to drive the threaded rod 707 to rotate, the threaded plate 706 slides and drives the connecting rod 703 to deflect, so that the mounting plate 4 can change the inclination angle of the kiln body 14 as it deflects, thereby avoiding a small inclination resulting in poor discharge of active metallurgical lime, or a large inclination angle resulting in insufficient combustion reaction time for the active metallurgical lime.

[0038] In this embodiment, a sliding groove 704 is provided on the inner wall of the fixed groove 701, and sliders 705 are fixedly connected at both ends of the threaded plate 706 and slide in cooperation with the inside of the sliding groove 704. The sliding of the slider 705 in the sliding groove 704 further restricts the threaded plate 706, making the sliding of the threaded plate 706 more stable.

[0039] In this embodiment, a sliding structure is formed between the threaded plate 706 and the inside of the fixing groove 701. The height of the threaded plate 706 is less than the depth of the inside of the fixing groove 701. The deeper fixing groove 701 is used to prevent the threaded plate 706 from protruding and affecting the range of the deflection angle of the mounting plate 4.

[0040] Furthermore, a guide plate 9 is fixedly connected to one side of the kiln body 14 . The cross section of the guide plate 9 is arc-shaped. The arc-shaped guide plate 9 can guide and discharge the active metallurgical lime material discharged from the kiln body 14 .

[0041] In addition, wheel belts 11 are fixedly connected to both sides of the surface of the kiln body 14, and rollers 6 are rotatably connected to both sides of the top of the mounting plate 4. The rotating rollers 6 and the wheel belts 11 can support the kiln body 14, thereby making the rotation of the kiln body 14 more stable and smooth.

[0042] The working principle and usage process of the utility model are as follows: first, the servo motor 702 is started to drive the threaded rod 707 to rotate, and the threaded rod 707 and the threaded plate 706 are matched by the threads, so that the threaded plate 706 slides and drives the connecting rod 703 to deflect, thereby allowing the mounting plate 4 to change the inclination angle of the kiln body 14 as it deflects, thereby meeting the production requirements of active metallurgical lime and avoiding the problem of poor discharge of active metallurgical lime due to a small inclination, or insufficient combustion reaction time of the active metallurgical lime due to a large inclination angle;

[0043] Afterwards, the active metallurgical lime raw material is added to the interior of the charging box 2 through the charging pipe 15, and then transported to the interior of the kiln body 14 by the charging box 2. At this time, the micro motor 302 is started to drive the cam 305 to rotate. The cam 305 is in rotational contact with the fixed block 304, so that the sliding plate 301 slides and drives the movable block 307 to slide on the surface of the slide rod 306 to compress the fixed spring 308, and drives the top end of the rubber block 303 to hit the bottom end of the charging box 2. After the cam 305 rotates away, the elastic force of the fixed spring 308 can be used to make the movable block 307 slide and drive the sliding plate 301 and the rubber block 303 to return to their original positions. Then, the collision and impact of the rubber block 303 sliding back and forth realizes the vibration feeding of the charging box 2, thereby preventing the active metallurgical lime from being blocked on the inner wall of the charging box 2 and affecting the feeding rate.

[0044] Then the drive motor 10 is started to rotate the small gear 12. The small gear 12 and the large gear 13 are meshed with each other, so that the large gear 13 rotates and drives the kiln body 14 to rotate, which is convenient for the combustion reaction of the active metallurgical lime. After the reaction is completed, it can be discharged from the side of the guide plate 9.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
