Description

Technical Field

[0001] This utility model relates to the technical field of aluminum liquid flow stabilization devices, and in particular to an aluminum liquid flow stabilization device for an aluminum electrolysis cell. Background Technology

[0002] With the rapid development of my country's aluminum electrolysis industry, the capacity of electrolytic cells has been continuously increasing. The mainstream cell types in aluminum electrolysis plants have evolved from 200kA and 300kA levels more than a decade ago to 500kA and 600kA levels, which has significantly improved the yield of primary aluminum per unit area and greatly reduced the cost of infrastructure projects. This reflects the many benefits that the large-scale and high-yield main equipment brings to the technical and economic efficiency.

[0003] An existing aluminum electrolysis cell aluminum liquid flow stabilization device, when the equipment is in actual use, is prone to causing a large number of impurities in the liquid to adhere to the filter screen, making it difficult for the equipment to self-clean the impurities on the filter screen, thus affecting the overall processing efficiency and quality of the equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an aluminum liquid flow stabilization device for aluminum electrolysis cells.

[0005] This utility model is achieved using the following technical solution: A device for stabilizing the flow of molten aluminum in an aluminum electrolysis cell, comprising: The anti-settlement equipment housing has a control cabinet fixedly installed on its side for controlling the circuit connection status. The housing is installed and fixedly connected to one side of the anti-settlement equipment housing; A drive motor, which is mounted in the mounting housing; A rotating shaft, one end of which is close to the drive motor is connected to the output shaft of the drive motor, and the other end of which is away from the drive motor is rotatably mounted on a fixed sleeve fixed to the inner wall of the anti-settlement equipment housing; A hybrid support is mounted on the rotating shaft and can rotate synchronously with the rotating shaft; The filter body is installed inside the housing of the anti-settling device; A fixed support ring is mounted on the rotating shaft; The cleaning bracket is fixedly installed on the fixed support ring and can move or rotate synchronously with the fixed support ring. in, Under the action of the drive motor driving the rotating shaft, the mixing bracket can stir the molten aluminum, and the cleaning bracket can clean the filter screen body.

[0006] Furthermore, the number of mounting housings is set to two, and the two mounting housings are symmetrically distributed front and back with the drive motor as the center; the left end of the drive motor is in contact with the side wall surface of the anti-settlement equipment housing.

[0007] Furthermore, the number of the hybrid stents is multiple.

[0008] Furthermore, the hybrid support is symmetrically distributed around the filter body.

[0009] Furthermore, the number of the mixing supports is set to two, and the two mixing supports are symmetrically distributed around the filter body.

[0010] Furthermore, the number of fixed support rings is set to two, and the two fixed support rings are symmetrically distributed with the filter body as the center.

[0011] Furthermore, the surface of the cleaning bracket is in contact with the surface of the filter body. Furthermore, the number of cleaning supports is set to two, and the two cleaning supports are symmetrically distributed around the filter body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a drive motor to rotate the shaft at high speed, which in turn drives two symmetrically distributed mixing supports to continuously agitate the molten aluminum. This breaks the oxide film on the surface of the molten aluminum, eliminates stratification caused by density differences, and makes the composition of the molten aluminum more uniform. At the same time, it suppresses the formation of vortices and avoids the entrainment of gas or impurities. By setting fixed support rings symmetrically distributed around the filter screen, the threaded connection allows for fine adjustment of the gap with the filter screen. When an increase in filtration resistance is detected, the pressure of the cleaning support on the filter screen can be changed by adjusting the position of the fixed support rings, thereby enhancing the slag removal effect.

[0013] This invention supports forward and reverse rotation by setting the bidirectional adjustable characteristic of the drive motor. When rotating in the reverse direction, the cleaning bracket can peel off stubborn clumps, ensuring smooth operation under extreme conditions. The mounting shell is symmetrically distributed front and back around the drive motor and is in close contact with the right end of the anti-settlement equipment shell, forming a stable three-point support structure, which effectively disperses the vibration load during equipment operation and suppresses shell deformation.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] Example

[0018] Please combine Figure 1-4 An aluminum electrolysis cell aluminum liquid stabilization device according to this embodiment includes an anti-settling equipment shell 1, a control cabinet 2 for controlling the circuit connection status is fixedly connected to the side of the anti-settling equipment shell 1, and an installation shell 3 is fixedly connected to the right end of the anti-settling equipment shell 1. A drive motor 4 is snapped into the inside of the installation shell 3.

[0019] A rotating shaft 5 is fixedly connected to the output end of the drive motor 4, and the rotating shaft 5 is rotatably connected to the fixed sleeve 6. A mixing bracket 7 is fixedly connected to the surface of the rotating shaft 5. A filter screen body 8 is installed inside the anti-settling equipment housing 1. A fixed support ring 9 is threadedly connected to the surface of the rotating shaft 5. A cleaning bracket 10 is fixedly connected to the fixed support ring 9. By setting the drive motor 4 to drive the rotating shaft 5 to rotate at high speed, the two mixing brackets 7, which are symmetrically distributed around the filter screen body 8, continuously agitate the aluminum liquid. This breaks the oxide film on the surface of the aluminum liquid, eliminates the stratification phenomenon caused by density differences, makes the aluminum liquid composition more uniform, and suppresses the formation of vortices to avoid the entrainment of gas or impurities. By setting the fixed support rings 9 to be symmetrically distributed around the filter screen body 8, the threaded connection between the fixed support rings 9 and the rotating shaft 5 allows for fine adjustment of the gap between the fixed support rings 9 and the filter screen body 8. When an increase in filtration resistance is detected, the pressure of the cleaning bracket 10 on the filter screen body 8 can be changed by adjusting the position of the fixed support rings 9, thereby enhancing the slag removal effect.

[0020] The outer shell 1 of the anti-settlement equipment adopts a rigid shell design and has a multi-layer buffer structure inside, which can effectively absorb the kinetic energy generated by the impact of molten aluminum and reduce the direct impact loss on the filter screen body 8.

[0021] As a further improvement to the above scheme, the number of mounting shells 3 is set to two, and the two mounting shells 3 are symmetrically distributed front and back around the drive motor 4. The left end of the drive motor 4 is in contact with the right end surface of the anti-settlement equipment shell 1. The mounting shells 3 are symmetrically distributed front and back around the drive motor 4 and are in close contact with the right end of the anti-settlement equipment shell 1, forming a stable three-point support structure, which effectively disperses the vibration load during equipment operation and suppresses shell deformation.

[0022] The fixed sleeve 6 is fixedly connected to the left end of the inner wall of the anti-settlement equipment shell 1, and the rotating shaft 5 is rotatably connected to the inside of the anti-settlement equipment shell 1.

[0023] The number of mixing supports 7 is set to two, and the two mixing supports 7 are symmetrically distributed around the filter body 8. By utilizing the bidirectional adjustable characteristic of the drive motor 4, the two mixing supports 7 support forward and reverse rotation. When rotating in the reverse direction, the cleaning support 10 can peel off stubborn clumps in the reverse direction to ensure unobstructed flow under extreme working conditions.

[0024] The number of fixed support rings 9 is set to two, and the two fixed support rings 9 are symmetrically distributed with the filter body 8 as the center.

[0025] The surface of the cleaning bracket 10 is in contact with the surface of the filter body 8. The number of cleaning brackets 10 is set to two, and the two cleaning brackets 10 are symmetrically distributed with the filter body 8 as the center.

[0026] The implementation principle of the aluminum liquid stabilization device in this embodiment of the application is as follows: A drive motor 4 drives a rotating shaft 5 to rotate at high speed, causing two mixing supports 7 to continuously agitate the aluminum liquid. This breaks the oxide film on the surface of the aluminum liquid, eliminates stratification caused by density differences, and makes the aluminum liquid composition more uniform. Simultaneously, it suppresses the formation of vortices, preventing the entrainment of gas or impurities. Fixed support rings 9 are symmetrically distributed around the filter body 8. The threaded connection between the fixed support rings 9 and the rotating shaft 5 allows for fine-tuning of the gap between the fixed support rings 9 and the filter body 8. When increased filtration resistance is detected, the pressure of the cleaning support 10 on the filter can be changed by adjusting the position of the fixed support rings 9, enhancing the slag removal effect. Utilizing the bidirectional adjustable characteristic of the drive motor 4, the rotating shaft 5 can be switched between forward and reverse rotation. When the rotating shaft 5 rotates in the reverse direction, the cleaning support 10 can peel off stubborn clumps, ensuring unobstructed flow under extreme operating conditions. The housing 3 is symmetrically distributed front and back around the drive motor 4 and is in close contact with the right end of the anti-settlement equipment housing 1, forming a stable three-point support structure that effectively disperses the vibration load during equipment operation and suppresses housing deformation.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
