[0001] This utility model relates to the technical field of spray granulation equipment, specifically to a spray granulation device for magnesium oxide and aluminum oxide. Background Technology
[0002] In the production of magnesium oxide and alumina, spray granulation is a critical process. Traditional granulation equipment faces numerous challenges. Previous equipment suffered from poor coordination between agitation and airflow, resulting in monotonous granulation and difficulty in fully dispersing and mixing materials, leading to slow granulation reactions. Furthermore, the tendency for materials to agglomerate made it difficult for them to uniformly contact the spray solution, affecting granule quality. Moreover, there was a lack of effective mechanisms for handling granules that did not meet the standard weight requirements; these granules accumulated within the equipment, wasting raw materials and hindering the granulation process. In addition, the structural design of traditional equipment easily caused materials to adhere to the container walls, resulting in material loss, increased cleaning and maintenance costs and difficulties, and reduced continuous operation capability.
[0003] By setting up a rotating device and a stirring device, the synergistic effect of airflow and stirring is optimized, the material dispersion and mixing effect is enhanced, the granulation reaction is accelerated, and at the same time, a special structure is used to allow substandard particles to re-participate in granulation, thereby improving raw material utilization and production efficiency, thus solving the drawbacks of traditional equipment.

[0017] Example: Please refer to Figure 1 - Figure 4 This utility model provides a technical solution: a magnesium oxide and aluminum oxide spray granulation device, comprising: a base 1, a granulation barrel 2 fixedly connected to the inner side wall of the base 1, a support ring 3 fixedly connected to the outer wall of the granulation barrel 2, a cyclone fan 4 fixedly connected to the outer wall of the top of the support ring 3, a feeding pipe 5 symmetrically fixedly connected to the inner wall of the top of the granulation barrel 2, and a sprayer 6 symmetrically fixedly connected to the inner wall of the top of the granulation barrel 2. The base 1 provides stable support for the entire device. The granulation barrel 2 serves as the core reaction vessel. The cyclone fan 4 is fixed to the support ring 3 on its outer wall. After the cyclone fan 4 is started, the air passes through the granulation barrel 2 and the polyurethane liner 8 in a direction tangential to the granulation barrel 2, and then blows into the internal space, forming a high-speed rotating airflow in the barrel, which drives the material to make circumferential motion, making the material mix more evenly and enhancing the granulation effect. The feeding pipe 5 is used to feed magnesium oxide and aluminum oxide raw materials, and the sprayer 6 sprays the solution required for granulation into the barrel.

The rotating device 7 includes a DC motor 71, and a transmission rod 72 is fixedly connected to the output end of the DC motor 71. An agitator 73 is fixedly connected to the outer wall of the transmission rod 72. When the DC motor 71 of the rotating device 7 is turned, it drives the transmission rod 72 to rotate, thereby driving the agitator 73 to work. In the agitator 73, the connecting frame 731 rotates with the transmission rod 72, and the inclined fan blades 732 on its outer wall agitate the material, so that the material is further dispersed and mixed in the rotating airflow, accelerating the granulation reaction.

The outer wall of the top of the transmission rod 72 is rotatably connected to the inner wall of the granulation barrel 2. The outer wall of the bottom of the transmission rod 72 is rotatably connected to the inner wall of the limit frame 9.
[0020] The stirring device 73 includes a connecting frame 731. An inclined fan blade 732 is fixedly connected to the outer wall of the connecting frame 731. A wind receiving plate 733 is provided below the inclined fan blade 732. A connecting frame 734 is fixedly connected to the outer wall of the wind receiving plate 733. A connecting strip 735 is fixedly connected to the bottom of the wind receiving plate 733. An inclined plate 736 is fixedly connected to the outer wall of the connecting strip 735. A fixing plate 737 is fixedly connected to the outer wall of the bottom of the connecting strip 735. Under the action of the airflow blown by the cyclone blower 4, the wind receiving plate 733 on the connecting frame 734 guides the airflow to the inclined fan blade 732 and the inclined plate 736 on the upper and lower sides. By disturbing the airflow, the stirring effect is enhanced. At the same time, the inclined direction of the inclined fan blade 732 and the inclined plate 736 is set so that the airflow moves upward while rotating. At this time, the particles that have not reached the standard weight during the granulation process will move upward under the push of the airflow and be in the spray and feeding position, thereby accelerating the granulation process.
[0021] The end of the inclined plate 736 away from the connecting strip 735 is fixedly connected to the outer wall of the connecting frame 731. The outer wall of the fixed plate 737 is fixedly connected to the outer wall of the bottom of the connecting frame 731. The end of the wind-receiving plate 733 away from the connecting frame 734 is fixedly connected to the outer wall of the connecting frame 731. The outer walls of the fixed plate 737 and the connecting strip 735 are both fixedly connected to the outer wall of the transmission rod 72. The outer walls of the connecting frame 731 and the connecting frame 734 are both fixedly connected to the outer wall of the transmission rod 72.

The bottom outer wall of the fixed plate 737 is rotatably connected to the top outer wall of the limiting frame 9.
[0022] Working principle:
[0023] During use, the base 1 provides stable support for the entire device. The granulation barrel 2 serves as the core reaction vessel, and its outer support ring 3 fixes the cyclone fan 4. After the cyclone fan 4 is started, the air flows tangentially through the granulation barrel 2 and the polyurethane liner 8, and then blows into the internal space, forming a high-speed rotating airflow inside the barrel. This causes the material to move in a circular motion, making the material mix more evenly and enhancing the granulation effect. The feeding pipe 5 is used to feed magnesium oxide and aluminum oxide raw materials. The sprayer 6 sprays the solution required for granulation into the barrel. The DC motor 71 of the rotating device 7 operates, driving the transmission rod 72 to rotate, which in turn drives the stirring device 73 to work. In the stirring device 73, the connecting frame 731 rotates with the transmission rod 72, and the inclined fan blades 732 on its outer wall stir the material, further dispersing and mixing the material in the rotating airflow, accelerating the granulation reaction. The air receiving plate 733 on the connecting frame 734 is affected by the airflow blown out by the cyclone fan 4. The airflow is guided to the inclined fan blades 732 and inclined plates 736 on the upper and lower sides. By disturbing the airflow, the stirring effect is enhanced. At the same time, the inclined direction of the inclined fan blades 732 and inclined plates 736 is set so that the airflow moves upward while rotating. At this time, the particles that have not reached the standard weight during the granulation process will be moved upward by the airflow and placed in the spray and feeding position, thereby accelerating the granulation process. The connecting frame 731, connecting strip 735 and fixing plate 737 firmly connect the various components to ensure stable operation of the device. At the same time, the connecting frame 731 moves on the polyurethane liner 8 and the fixing plate 737 slides on the limit frame 9 to reduce material residue. The polyurethane liner 8 in the granulation tank 2 prevents material from sticking to the tank wall and iron impurities from contaminating the interior. The limit frame 9 supports and limits the transmission rod 72 to ensure stable operation of the device for a long time and improve the efficiency and quality of magnesium oxide and aluminum oxide spray granulation.
