Technical Field

[0001] The utility model relates to the technical field of waste recycling, in particular to a lithium dissolving reaction tank for recycling electrolytic aluminum waste. Background Art

[0002] Electrolytic aluminum scrap refers to the scrap generated during the production and processing of aluminum materials, which may contain a certain amount of aluminum. After proper treatment, these scraps can be recycled and reused. The treatment methods of electrolytic aluminum scrap usually include collection, classification, cleaning, smelting and other steps to maximize the recovery of aluminum resources in the scrap and reduce the impact on the environment. Aluminum is a sustainable and recyclable metal material. By recycling discarded electrolytic aluminum scrap, resource waste can be reduced, environmental pollution can be reduced, and it is also beneficial to save energy and reduce greenhouse gas emissions.

[0003] In the process of recycling electrolytic aluminum waste, it is usually necessary to react inside the reaction tank. However, during the reaction, the material in the reaction tank tube needs to be stirred. The traditional stirring method usually rotates at a constant speed in the same direction, and this stirring effect is relatively poor.

[0004] Therefore, we propose a lithium dissolving reaction tank for recycling electrolytic aluminum waste in order to solve the problems raised above. Utility Model Content

[0007] Furthermore: a partition plate is fixed above the interior of the reaction tank body, and the sector gear, incomplete internal gear, incomplete external gear and fixed rod are located on the upper part of the partition plate, and several stirring assemblies are located on the lower part of the partition plate.

[0008] A bearing is provided at the connection between the rotating shaft and the partition plate.

[0009] The stirring assembly comprises a fixed sleeve fixed on the outer surface of the rotating shaft, and a plurality of stirring rods are fixed on the outer surface of the fixed sleeve at equal intervals along the circumferential direction.

[0010] The outer surface of the rotating shaft, the outer surface of the stirring rod and the inner wall of the reaction tank body are all provided with an anti-corrosion coating, and the anti-corrosion coating is made of polytetrafluoroethylene material.

[0011] The bottom of the reaction tank body is provided with a plurality of support angles along the circumferential direction.

[0012] Beneficial effects of the utility model:

[0013] The utility model is provided with a sector gear, an incomplete internal gear and an incomplete external gear inside a reaction tank body. When the motor drives the sector gear to rotate and drives the incomplete internal gear to rotate, the incomplete internal gear drives the incomplete external gear to rotate in a forward slow direction through a fixed rod. The incomplete external gear can drive a plurality of stirring components to rotate in a forward slow direction through a rotating shaft and stir the material in the reaction tank body at the same time. When the motor drives the sector gear to rotate and drives the incomplete external gear, the incomplete external gear can drive a plurality of stirring components to rotate in a fast reverse direction through the rotating shaft and stir the material in the reaction tank body, thereby realizing stirring of the material in the reaction tank body in a fast, slow, forward and reverse direction, thereby improving the efficiency of accelerating mixing and improving the use effect of the reaction tank.

The arrangement of the plurality of support angles 13 supports the reaction tank body 1. The upper part of the tank body 1 is provided with a plurality of feed ports 2 at equal intervals along the circumferential direction, so that after each discharge port 2 is connected to an external conveying device (not shown in the figure), different types of materials can be put into the interior of the reaction tank body 1.

[0021] A partition plate 11 is fixed above the interior of the reaction tank body 1, and the partition plate 11 divides the interior of the reaction tank body 1 into an upper chamber and a lower chamber. The partition plate 11 is arranged to divide the interior of the reaction tank body 1, thereby reducing the spraying of corrosive materials on the sector gear 5, the incomplete internal gear 6 or the incomplete external gear 7. The inner wall of the lower chamber is also coated with polytetrafluoroethylene material, thereby playing a role in corrosion resistance and extending the service life of the reaction tank body 1.

[0022] A motor 4 is installed on the top of the reaction tank body 1, and the output shaft of the motor 4 extends to the interior of the upper chamber where a fan gear 5 is installed, and an incomplete internal gear 6 and an incomplete external gear 7 are installed inside the upper chamber, and the fan gear 5 is located between the incomplete internal gear 6 and the incomplete external gear 7, and a plurality of fixing rods 8 are fixed to the bottom of the incomplete external gear 7 at equal intervals along the circumferential direction, and a plurality of fixing rods 8 are fixedly connected to the same incomplete internal gear 6, thereby fixing the incomplete internal gear 6 and the incomplete external gear 7.

[0023] A rotating shaft 9 is fixed at the center of the bottom of the incomplete external gear 7. The bottom end of the rotating shaft 9 passes through the partition plate 11 and extends to the interior of the lower chamber, where a plurality of stirring components 10 are installed. It should be noted that a bearing 12 is provided at the connection between the rotating shaft 9 and the partition plate 11. The setting of the bearing 12 supports the rotating shaft 9. The stirring component 10 includes a fixed sleeve 101 fixed to the outer surface of the rotating shaft 9, and a plurality of stirring rods 102 are fixed to the outer surface of the fixed sleeve 101 at equal intervals along the circumferential direction.

If it is necessary to dissolve the sodium fluoroaluminate and lithium fluoroaluminate, hydrochloric acid and aluminum chloride are then put into the interior of the reaction tank body 1, and then the motor 4 is turned on. The output shaft of the motor 4 can drive the fan gear 5 to rotate.
