Description

Technical Field

[0001] The utility model relates to the field of aluminum ash processing equipment, in particular to secondary aluminum ash wet processing equipment. Background Art

[0002] Scrap aluminum ash mainly comes from the smelting and recycling process of aluminum, including scum and skimming produced during the metallurgical melting process of electrolytic aluminum, cast aluminum, and recycled aluminum, as well as the residue left after subsequent treatment processes such as ash roasting and ball milling. There is also a small amount of aluminum in the scrap aluminum ash, which can be extracted through appropriate reaction treatment.

[0003] In the process of aluminum ash refining, the hydrolysis leaching process is often used. The characteristic of this process is to remove the fluoride and chloride in the aluminum ash slurry. To complete the removal, additives need to be added to the aluminum ash slurry for reaction, and these reactions need to be carried out under high temperature conditions. If the aluminum ash slurry is continuously heated, aluminum ash will stick to the upper end of the liquid surface, resulting in a waste of raw materials.

[0004] In the patent number "CN218222252U" and the patent name "A device for fully stirring aluminum ash slurry", a set of plate-shaped stirring paddles that do not contact the tank body are used to remove the aluminum ash slurry adhering to the inner wall of the tank. However, such a thin plate will deform during the rotation process, making it impossible to effectively remove the aluminum ash slurry adhering to the inner wall of the tank. Utility Model Content

[0005] In view of the defects of the prior art, the technical problem to be solved by the utility model is to provide a secondary aluminum ash wet processing equipment, which can effectively prevent the scraper from deforming during rotation, improve the ability to scrape off the adhered aluminum ash slurry, and achieve sufficient stirring of the aluminum ash slurry.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A secondary aluminum ash wet processing equipment includes a tank body, a rotating assembly and a moving assembly. The top of the tank body is provided with a feeding port, the bottom of the tank body is provided with a discharging port, the moving assembly is arranged on the top of the tank body, the rotating assembly includes a rotating shaft, a scraper and a stirring knife, the rotating shaft is arranged at the center of the tank body, the rotating shaft is fixed to the power output end of the moving assembly, the rotating shaft vertically extends a scraper frame in the middle, the scraper is installed at the end of the scraper frame, the end of the scraper contacts the inner wall of the tank body, and the stirring knife is fixed to the end of the rotating shaft away from the moving assembly.

[0008] With such a structure, the motion component drives the shaft to rotate, and the scraper frame on the shaft drives the scraper to rotate. The scraper frame and the scraper are hard-connected, and the scraper is always in contact with the inner wall of the tank body, constantly scraping off the aluminum ash slurry adhering to the inner wall of the tank body, and the stirring blade drives the aluminum ash slurry liquid to rotate in the tank body, fully stirring it, so that the aluminum ash fully reacts. It effectively prevents the scraper from deforming during the rotation process, improves the ability to scrape off the adhering aluminum ash slurry, and realizes the full stirring of the aluminum ash slurry.

[0009] Preferably, the stirring blade is provided with three sets of blades, and the cutting edges of the blades face the rotation direction of the rotating shaft, so as to effectively cut the large solids in the aluminum ash slurry, make the components of the aluminum ash slurry more delicate, mix the components evenly, and improve the mixing degree between the components of the aluminum ash slurry.

[0010] Preferably, the blade angle is 45°-50°. Such a design can form a vortex in the tank body, and the various components of the aluminum ash slurry are mixed more evenly, further improving the mixing degree between the various components of the aluminum ash slurry.

[0011] Preferably, the end of the scraper that contacts the inner wall of the tank is made of nylon material. Nylon material has extremely high wear resistance and strength, can fully scrape off the adhered aluminum ash slurry, and has a long service life, thereby increasing the service life of the scraper.

[0012] Preferably, the tank body includes an inner layer and an outer layer, wherein the inner layer is embedded in the outer layer, and a heating layer is formed between the inner layer and the outer layer. The design of the inner and outer layers can insulate the inner layer, prevent heat loss, and improve energy efficiency.

[0013] Preferably, a heating component is further included, and the heating component is arranged in the heating layer. If the heating component is directly installed at the bottom of the inner liner layer, the local temperature will be too high, causing the aluminum ash slurry to adhere to the bottom, thereby reducing the reaction efficiency of the aluminum ash slurry. Installing it in the heating layer can effectively prevent the local temperature from being too high, and improve the reaction efficiency of the aluminum ash slurry.

[0014] Preferably, the motion assembly includes a motor and a reducer, the output end of the motor is connected to the input end of the reducer, the reducer is fixed to the top of the tank, and the output end of the reducer is fixedly connected to the rotating shaft. The reducer reduces speed and increases torque, thereby improving the ability of the scraper to scrape off the sticking aluminum ash slurry.

[0015] As a preferred embodiment, the device further comprises a support frame, which is mounted at the bottom of the tank body and has a rotatable adjustment plate at the bottom of the support frame, which can adjust the balance of the tank body and improve the stability of the device during operation.

[0016] As a preference, it also includes an inner temperature sensor and an outer temperature sensor, wherein the inner temperature sensor is installed on the inner layer and the outer temperature sensor is installed in the heating layer. The operating temperature can be adjusted at any time to improve the reaction efficiency of the aluminum ash slurry.

[0017] Preferably, the tank body further comprises an exhaust pipe, which is arranged on the top of the tank body, communicates with the inner liner layer, and is connected to a negative pressure device. Ammonia gas is generated during the reaction of the aluminum ash slurry, and the negative pressure device is used to extract the generated gas to prevent safety hazards.

[0018] In summary, such secondary aluminum ash wet processing equipment can effectively prevent the scraper from deforming during rotation, enhance the ability to scrape off the adhered aluminum ash slurry, and achieve full stirring of the aluminum ash slurry. BRIEF DESCRIPTION OF THE DRAWINGS
