Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolytic cell construction and maintenance equipment, and in particular to an aluminum outlet shaping device for electrolytic cells. Background Technology

[0002] In the cryolite-alumina molten salt electrolysis process, aluminum is deposited on the cathode. The aluminum produced each day and night must be promptly sucked out using a ladle and sent to the aluminum processing plant for casting. When sucking out the molten aluminum, the ladle pipe is inserted obliquely into the electrolytic cell. When the horizontal section of the suction pipe is below the electrolyte level and enters the aluminum cell, the compressed air source for the ladle is turned on, and the molten aluminum in the electrolytic cell is extracted using the siphon principle. Because the ladle pipe forms a 30-40° angle with the ladle body, the ladle must descend along with the aluminum level in the electrolytic cell, and the pipe moves forward as it descends. Therefore, the aluminum outlet of the electrolytic cell has requirements not only in diameter but also in length. Furthermore, the aluminum outlet is also the outlet for slag removal, and its size must be compatible with the use of a circular shovel. However, in actual production operations, due to factors such as replacing corner anodes and electrolyte overflow at the aluminum outlet, the shape of the aluminum outlet cannot be guaranteed to be formed to meet the requirements of the suction pipe insertion and shovel retrieval (it is too small). The daily operations of aluminum tapping and slag removal in electrolytic cells are affected, requiring manual repair using electrolytes. However, manual repair of the aluminum tapping port mainly relies on the work experience of the employees, and the results of repairs by different people vary greatly. Furthermore, manual repair cannot achieve the desired aluminum tapping and slag removal efficiency. This not only affects the efficiency and cleanliness of slag removal from the electrolytic cells but also impacts the ladle suction operation. It may prevent the suction pipe from entering the molten aluminum, leading to suction pipe blockage, electrolyte buildup, and other issues, thus prolonging the suction operation time.

[0017] like Figures 1-2 As shown, an aluminum outlet shaping device for an electrolytic cell includes a mold 1 and two symmetrically arranged connecting rods 2 connected to one side of the bottom of the mold 1. The mold 1 is a semi-circular plate with a thickness greater than 10 mm. The bottom ends of the arc-shaped opening of the mold 1 are respectively connected to the connecting rods 2. The mold 1 is made of ceramic material, which can effectively reduce the impact of high-temperature corrosion of the mold 1 on the iron content of the molten aluminum. The radius R of the arc of the mold 1 is made according to 1.25 times the maximum diameter of the ladle tube and the shovel.

[0018] The other end of the connecting rod 2 is connected to the rotating shaft via a bearing. Insulating wheels 3 are connected to both ends of the rotating shaft to prevent electric shock and burns from high temperatures.

[0019] Two symmetrically arranged push rods 4 are connected to the rotating shaft. The bottom of the push rod 4 is connected to the bearing. The included angle between the connecting rod 2 and the push rod 4 is 90°, which can effectively ensure that the shaped aluminum outlet meets the production operation requirements.

[0020] The mold 1 and the push rod 4 are connected by a reinforcing rod 6.

[0021] A positioning plate 5 is connected to the bottom of the connecting rod 2 near the mold 1. The positioning plate 5 is a right-angled triangle, with the side of the positioning plate 5 closest to the mold 1 being a right-angled side. The distance X from the positioning plate 5 to the inner side of the mold 1 is determined by the maximum distance the lifting suction pipe travels along the length of the groove.

[0022] The top of the push rod 4 is a handle bent at 90°, and an insulating and heat-insulating sleeve 7 is fitted on the handle to prevent electric shock and high-temperature burns.

[0023] Due to the large magnetic field in the electrolytic cell, the connecting rod 2, bearing, push rod 4, positioning plate 5, and reinforcing rod 6 are made of stainless steel to reduce the influence of the magnetic field.

[0024] The operation process of this utility model is as follows:

[0025] When in use, push the device to the aluminum outlet end of the electrolytic cell that needs to be shaped, push the insulating wheel 3 on the device onto the horizontal plate 8 on the edge of the electrolytic cell, and make the right-angled edge of the positioning plate 5 rest on the edge plate 9. Then lift the push rod 4 so that the connecting rod 2 presses on the edge plate 9. At this time, the mold 1 and the electrolyte block 10 in the middle of the corner anode form a certain gap. Use an old shovel to scoop out the electrolyte liquid 11 from the aluminum outlet and continuously pour it into the gap between the mold 1 and the electrolyte block 10. When the electrolyte liquid cools down, it will form a solid hole inner wall according to the mold 1, thereby forming the aluminum outlet required for aluminum extraction and slag removal, which facilitates subsequent aluminum extraction and slag removal operations.

[0026] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
