Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum production technology, and in particular to an electrolytic aluminum impurity separation device. Background Technology

[0002] Electrolytic aluminum is metallic aluminum obtained through electrolysis. During the production process, some impurities are inevitably introduced or generated. The presence of these impurities significantly affects the mechanical properties, electrical conductivity, and corrosion resistance of the final aluminum product. Therefore, before the molten aluminum is cast, impurity separation treatment is usually required to improve the purity and quality of the aluminum product. Currently, various separation equipment are commonly used in industry to remove non-metallic inclusions and other impurities from the molten aluminum using physical or chemical methods.

[0003] However, in existing impurity separation operations, insufficient mixing and stirring often lead to unsatisfactory separation results. Furthermore, containers or components used to hold and filter molten aluminum tend to accumulate residue after prolonged use, requiring cleaning and maintenance. Some equipment has complex structures, and the disassembly process for key internal aggregate or filter components is cumbersome, increasing the workload for operators and affecting the efficiency of continuous operation, thus its practicality needs improvement.

Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0016] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0017] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] This utility model provides the following: Figure 1-5 An electrolytic aluminum impurity separation device is shown, comprising a base plate 1, a fixed frame 2 fixedly connected to the base plate 1, an outer separation box 3 fixedly mounted on the fixed frame 2, a detachable inner collection box 4 installed inside the outer separation box 3, a drive motor 5 and two supports 6 fixedly mounted on the base plate 1, bearing seats 7 fixedly mounted on the top of each of the two supports 6, and rotating rods 8 passing through the bearing seats 7, the output end of the drive motor 5 is provided with a first transmission wheel 9, a second transmission wheel 10 is fixedly sleeved on the rotating rod 8, and the first transmission wheel 9 and the second transmission wheel 10 are connected by a transmission belt 11. A drive shaft 12 is rotatably connected to the bottom wall of the box 3. A first bevel gear 13 is fixedly connected to the bottom end of the drive shaft 12. A second bevel gear 14 that meshes with the first bevel gear 13 is fixedly sleeved on the rotating rod 8. A linkage shaft 15 is rotatably connected to the bottom wall of the inner collection box 4, and the bottom end of the linkage shaft 15 is engaged with the top end of the drive shaft 12. Multiple limiting pillars 16 inserted into the bottom wall of the outer separation box 3 are fixedly connected to the bottom of the inner collection box 4. Multiple stirring rods 17 located inside the inner collection box 4 are fixedly connected to the upper part of the linkage shaft 15. A drain outlet 18 is connected to the bottom of the outer separation box 3.

[0019] like Figure 3 and Figure 4 As shown, in this utility model, the drive shaft 12 is rotatably connected to the bottom wall of the outer separation box 3 through the first bearing 19 and the connection is sealed, which ensures that the drive shaft 12 can rotate smoothly on the bottom wall of the outer separation box 3. At the same time, the sealing design effectively prevents the aluminum liquid or cleaning liquid in the outer separation box 3 from leaking from the rotatable connection, ensuring the safety of equipment operation and the cleanliness of the working environment.

[0020] like Figure 4 As shown, in this utility model, the top end of the drive shaft 12 is inserted into the bottom end of the linkage shaft 15. The top end of the drive shaft 12 is provided with a cross-shaped locking block, and the bottom end of the linkage shaft 15 is provided with a cross-shaped locking groove that matches the cross-shaped locking block. When the inner collection box 4 is installed in place, the cross-shaped locking groove at the bottom end of the linkage shaft 15 is precisely fitted onto the cross-shaped locking block at the top end of the drive shaft 12, so that the rotation of the drive shaft 12 can be accurately and efficiently transmitted to the linkage shaft 15, thereby driving the stirring rod 17 to perform stirring operations. At the same time, when the inner collection box 4 needs to be disassembled, it can be easily separated from the drive shaft 12 simply by lifting it upwards. The operation is convenient and does not require complicated disassembly tools.

[0021] like Figure 4 As shown, the bottom wall of the outer separation box 3 in this utility model is provided with a limiting slot for the installation of the limiting support column 16 and to limit its rotation, which ensures that the inner aggregate box 4 remains stable during the mixing process and does not rotate or shift. When the inner aggregate box 4 is placed inside the outer separation box 3, the limiting support column 16 is inserted into the limiting slot, thereby effectively limiting the rotation of the inner aggregate box 4 around its axis, ensuring the stability of the mixing operation and the fixation of the relative position between the inner aggregate box 4 and the outer separation box 3.

[0022] like Figure 3 and Figure 4 As shown, in this utility model, the linkage shaft 15 is rotatably connected to the inner aggregate box 4 through the second bearing 20, which provides stable support for the high-speed rotation of the linkage shaft 15, reduces the frictional resistance during the rotation process, and further enhances the structural strength of the bottom of the inner aggregate box 4, ensuring the sealing and reliability of the connection between the linkage shaft 15 and the inner aggregate box 4.

[0023] like Figure 1-4 As shown, the inner collection box 4 of this utility model has several filter holes on its side wall and bottom wall, which allows the pure aluminum liquid after stirring and separation to pass through smoothly, while trapping larger non-metallic inclusions or other solid impurities inside the inner collection box 4.

[0024] In this utility model, the drain outlet 18 is equipped with a solenoid valve. The operator can control the opening and closing of the solenoid valve to precisely control the timing and amount of aluminum liquid discharge, which facilitates the subsequent collection and transfer of pure aluminum liquid. At the same time, when it is necessary to clean the inside of the equipment, the cleaning wastewater can also be discharged through the drain outlet 18.

[0025] Working Principle: In practical implementation, the inner collection box is first aligned and inserted into the limiting slot on the bottom wall of the outer separation box via the limiting support column, ensuring the inner collection box is stably placed inside the outer separation box. At this time, the cross groove at the bottom of the linkage shaft engages with the cross block at the top of the drive shaft, achieving power transmission. Next, the electrolytic aluminum liquid to be treated and related separating agents are poured into the inner collection box through the top opening of the outer separation box. The drive motor is started, and its output drives the first transmission wheel to rotate. Through the transmission belt, the second transmission wheel and the rotating rod rotate synchronously. The second bevel gear on the rotating rod rotates accordingly, thereby meshing and driving the first bevel gear and the drive shaft to rotate. The drive shaft, through the engagement of the cross block at its top and the cross groove at the bottom of the linkage shaft, drives the linkage shaft and the stirring rod to rotate at high speed inside the inner collection box. The stirring rod thoroughly mixes the molten aluminum and the separating agent, promoting the separation of non-metallic inclusions and other impurities from the molten aluminum. The separated pure molten aluminum permeates through the filter holes on the side and bottom walls of the inner collection tank into the gap between the outer and inner collection tanks, while the impurities are trapped in the inner collection tank. After the impurity separation is completed, the solenoid valve at the drain outlet is opened, and the pure molten aluminum in the outer separation tank is discharged and collected through the drain outlet. When cleaning and maintenance are required, the drive motor is turned off, the stirring operation is stopped, and the inner collection tank is lifted upwards to disengage the limit support from the limit slot, separating the linkage shaft from the drive shaft. The inner collection tank can then be removed entirely from the outer separation tank to clean the trapped impurities. After cleaning, the inner collection tank is reinstalled into the outer separation tank following the same installation steps to continue the impurity separation operation. The entire process is convenient to operate, with thorough stirring, good impurity separation effect, and the disassembly and cleaning of the inner collection tank is simple and quick, effectively ensuring the continuous operation efficiency of the equipment.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
