Technical Field

[0001] This utility model relates to the technical field of alumina production equipment, specifically a rotary cooling device for alumina after calcination. Background Technology

[0002] The rotary cooling device after alumina calcination is one of the key pieces of equipment in the alumina production process. It is mainly used to rapidly cool alumina (usually α-Al2O3) after high-temperature calcination to a suitable temperature, while recovering waste heat.

[0003] However, as alumina is added to the rotary cooling device through the feed pipe, it tends to accumulate inside the feed pipe as the amount of alumina increases. This can cause the alumina to become blocked in the feed pipe and unable to fall into the tank, thus increasing the need for workers to clear the blockage. Furthermore, clearing the blockage also affects the efficiency of alumina processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rotary cooling device for alumina after calcination, which has the advantages of preventing alumina from clogging the feed pipe, maintaining the flow of alumina in the storage tank, and replacing manual unclogging of alumina, thus solving the problems mentioned in the background art.

Connecting rods 6 are evenly distributed on the outer wall of the rotating shaft 5. The connecting rods 6 connect the rotating shaft 5 to a stirring rod 7. The stirring rod 7 is fixedly installed at the end of the connecting rod 6 away from the rotating shaft 5. A bracket 8 for connecting the storage tank 3 is movably sleeved on the upper outer wall of the rotating shaft 5. The installation of the bracket 8 provides a platform for the installation of the rotating shaft 5.

[0023] Rotary drums 10 are rotatably connected to the left and right sides of the tank body 1, respectively. The rotatable connection allows the tank body 1 to rotate between the left and right rotating drums 10. A feed pipe 9 is fixedly installed at the upper end of the left rotating drum 10, and the end of the feed pipe 9 away from the rotating drum 10 is fixedly connected to the lower end of the storage tank 3. The feed pipe 9 serves to connect the tank body 1 and the storage tank 3. A rotating component 11 is provided on the outer wall of the left end of the tank body 1. The rotating component 11 provides power for the rotation of the tank body 1. An annular block 12 is fixedly sleeved on the outer wall of the right end of the tank body 1. The rolling of the annular block 12 on the roller 24 strengthens the stability of the tank body 1 during rotation.

A discharge pipe 13 located on the left side of the cooling box 4 is fixedly installed at the lower end of the right rotating drum 10.

[0024] Please see Figure 2 and Figure 5 A locking block 14 is fixedly installed at the lower end of the bracket 8, and the inner wall of the locking block 14 is movably engaged with the outer wall of the upper end of the storage tank 3. A movable plate 15 located outside the storage tank 3 is provided inside the locking block 14. The movement of the movable plate 15 inside the locking block 14 increases the tightness of the locking block 14 on the storage tank 3. A threaded rod 16 is movably connected to the outer side of the movable plate 15, and the outer wall of the threaded rod 16 is threadedly engaged with the inner wall of the locking block 14. The threaded connection allows the threaded rod 16 to rotate in a circular motion while driving horizontal movement.

[0025] The upper end of the connecting rod 6 is fixedly installed with a drive motor 17 located above the bracket 8. The bracket 8 provides a platform for the installation of the drive motor 17, and a reducer is provided on the output shaft of the drive motor 17. The reducer is used to adjust the speed of the output shaft of the drive motor 17. The lower end of the drive motor 17 is fixedly connected to the upper end face of the bracket 8.

[0026] Please see Figure 6 and Figure 4 A baffle 18 is fixedly installed on the left side of the cooling box 4 at the right end of the rotating drum 10. The baffle 18 provides a channel for the gas in the tank 1 to enter the interior of the cooling box 4. An exhaust pipe 19 is fixedly connected to the upper end of the cooling box 4. An inlet pipe 20 is fixedly installed on the right side of the cooling box 4. A spiral pipe located inside the cooling box 4 is installed between the inlet pipe 20 and the outlet pipe 21. An outlet pipe 21 located in front of the inlet pipe 20 is fixedly connected to the right side of the cooling box 4.

[0027] The rotating assembly 11 includes a driven gear 111 and a driving gear 112. The driven gear 111 and the driving gear 112 are meshed with each other. The meshing connection allows the circumferential rotation of the driving gear 112 to provide power for the rotation of the driven gear 111. The inner wall of the driven gear 111 is fixedly sleeved with the outer wall on the left side of the tank 1. A rotary motor 22 is fixedly installed on the left side of the driving gear 112, and a second reducer is provided on the output shaft of the rotary motor 22. The second reducer is used to adjust the speed of the output shaft of the rotary motor 22. A frame 23 is fixedly installed on the outer wall of the rotary motor 22, and the frame 23 provides a platform for the installation of the rotary motor 22.

[0028] Working principle: In use, firstly, the material is added from inside the storage tank 3, through the feed pipe 9, and then into the rotating drum 10 on the left. Since the conveying auger 2 is externally connected to a drive motor, the drive motor drives the conveying auger 2 to rotate inside the tank 1, allowing the conveying auger 2 to transport the material. Then, the power to the rotary motor 22 is turned on. After the rotary motor 22 is turned on, it drives the rotation of the drive gear 112. Due to the meshing connection between the drive gear 112 and the driven gear 111, the circumferential rotation of the drive gear 112 drives the rotation of the driven gear 111. The rotating cylinder 10 on both sides of the tank 1 drives the tank body 1 to rotate. To enhance the stability of the tank body 1 during rotation, the annular block 12 rotates on the roller 24. Subsequently, to prevent material from clogging the feed pipe 9, the power of the drive motor 17 is turned on. After the drive motor 17 is turned on, it drives the rotation of the stirring rod 7 through the connection of the connecting rod 6. The rotation of the stirring rod 7 inside the storage tank 3 and the feed pipe 9 maintains the flow of material in the feed pipe 9, thereby preventing material from clogging inside the feed pipe 9. In addition, the cooling box 4 can play a cooling role. Finally, the material is discharged from the discharge pipe 13 to the outside of the tank body 1.
