Description

Technical Field

[0001] This utility model relates to the field of busbar lifting frame technology, specifically providing a dust removal device for an anode busbar lifting frame of a 500kA electrolytic cell. Background Technology

[0002] In aluminum electrolysis production, the electrolytic cell is the core equipment for alumina electrolysis. The anode carbon block assembly is continuously consumed during electrolysis and needs to be periodically lowered to maintain a suitable electrode spacing. The anode busbar lifting frame is one of the key structural components of the electrolytic cell. It bears the powerful DC current conducted through the anode busbar and is responsible for accurately and stably raising or lowering the entire anode carbon block assembly to compensate for anode consumption, adjust the electrode spacing, and maintain continuous and stable operation of electrolysis. This frame is typically welded from large steel structures, possessing extremely high strength, rigidity, and conductivity. Its operational reliability and positioning accuracy directly affect the current efficiency, energy consumption, and production safety of the electrolytic cell.

[0003] During the operation of the electrolytic cell, a large amount of alumina dust, fluoride volatiles, and electrolyte volatiles are generated under high-temperature conditions. These substances continuously settle and accumulate on the surface of the anode busbar lifting frame and its transmission components, forming hard ash deposits. These ash deposits not only increase the weight load on the frame, but more seriously, they significantly reduce the conductivity of the anode busbar system, affect heat dissipation, accelerate the corrosion of metal components, and may infiltrate the transmission mechanism, leading to jamming, accelerated wear, lifting malfunction, or even equipment damage, threatening the stable operation of the electrolytic cell.

[0004] Existing conventional dust removal devices are limited to a preset area due to their fixed location, and cannot be adapted to the dynamic operation of the anode busbar lifting frame. Utility Model Content

[0006] In a first aspect, this utility model provides a dust removal device for an anode busbar lifting frame of a 500kA electrolytic cell, including a blowing assembly and an air duct adjustment assembly. The air duct adjustment assembly includes a corrugated pipe, a mounting frame, air guide plates, a driving component, and a lifting component.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is combined with Figures 1 to 5 The embodiments shown illustrate the technical solution of this utility model:

[0028] This utility model embodiment provides a dust removal device for the anode busbar lifting frame of a 500kA electrolytic cell, such as... Figures 1 to 5 As shown, in an exemplary embodiment, see reference Figure 1 and Figure 2 The system includes a blower assembly 2 and an air duct adjustment assembly 1. The air duct adjustment assembly 1 includes a corrugated pipe 11, a mounting frame 12, air guide plates 13, a drive component 14, and a lifting component 16. One end of the corrugated pipe 11 is connected to the air outlet of the blower assembly 2, and the other end points towards the anode busbar lifting frame. The mounting frame 12 is located at the end of the corrugated pipe 11 away from the blower assembly 2. Several air guide plates 13 are arranged in a row perpendicular to the direction of gravity on the side of the mounting frame 12 away from the corrugated pipe 11, and are rotatably connected to the mounting frame 12 along the direction of gravity. The drive component 14 is located on the mounting frame 12 and provides rotational driving force for the air guide plates 13. The lifting component 16 is located on the side of the mounting frame 12 away from the drive component 14 and provides moving driving force for the mounting frame 12 along the direction of gravity.

[0029] In one embodiment, the lifting component 16 may be a cylinder; in another embodiment, the lifting cylinder may also be a scissor lift.

[0030] Specifically, the airflow generated by the blowing assembly 2 is delivered to the mounting frame 12 via the corrugated pipe 11. The driving component 14 drives the air guide plate 13 to rotate to adjust the blowing angle, and the lifting component 16 moves the mounting frame 12 along the direction of gravity to adjust the dust removal height. The corrugated pipe 11 provides a flexible connection, adapting to changes in the position between the mounting frame 12 and the blowing assembly 2; the rotation of the air guide plate 13 flexibly adjusts the airflow direction, expanding the dust removal coverage area; and the lifting component 16 moves the mounting frame 12 along the direction of gravity, adapting to the dust removal needs of different heights of the anode busbar lifting frame. This solves the shortcomings of existing devices with fixed positions that cannot adapt to the dynamic operation of the frame, achieving dynamic adjustment of the dust removal position and improving the comprehensiveness and effectiveness of dust removal.

[0031] See Figure 3 In an exemplary embodiment, the driving component 14 includes: a limiting plate 141, a rack 142, a gear 143, a limiting block 144, a threaded rod 145, and a driving motor 146. The limiting plate 141 is disposed on the mounting frame 12 along the array direction of the plurality of driving components 14, and a limiting groove (not shown) is formed on the side of the limiting plate 141 near the bellows 11. The rack 142 slides between the limiting plate 141 and the mounting frame 12. The gear 143 is connected to the rotating shaft of the air guide plate 13 and meshes with the rack 142. The limiting block 144 is connected to the side of the rack 142 away from the gear 143 and slides in the limiting groove. The threaded rod 145 is rotatably connected to the mounting frame 12 and threadedly connected to the limiting block 144. The driving end of the driving motor 146 is collinear with one end of the threaded rod 145.

[0032] The limiting groove limits the limiting block 144 to prevent the rack 142 from sliding beyond the meshing range with the gear 143.

[0033] It should be noted that, under the action of the limiting groove, the maximum rotation range of the air guide plate 13 is 180°, and when the air guide plate 13 is at the edge of the range, the direction of the air guide plate 13 is nearly parallel to the setting direction of the rack 142, two adjacent air guide plates 13 abut against each other, and the side of the air guide plate 13 near the edge of the mounting frame 12 abuts against the side of the mounting frame 12.

[0034] Specifically, the drive motor 146 drives the threaded rod 145 to rotate, causing the limiting block 144 to slide along the limiting groove, which in turn causes the rack 142 to move. The rack 142 meshes with the gear 143, driving the air guide plate 13 to rotate. The limiting plate 141, in conjunction with the limiting groove, restricts the direction and distance of movement of the rack 142, preventing it from deviating and limiting its maximum range of movement. The meshing transmission between the rack 142 and the gear 143 enables synchronous angle adjustment of multiple air guide plates 13, improving adjustment consistency. The threaded connection between the threaded rod 145 and the limiting block 144 converts the rotational motion of the drive motor 146 into the linear motion of the rack 142, achieving high transmission accuracy. The drive motor 146 provides stable power for the entire driving process. Through the above structural coordination, precise and synchronous control of the angle of the air guide plate 13 is achieved, enhancing the controllability of the dust removal direction.

[0035] See Figure 2 and Figure 5 In an exemplary embodiment, a filter plate 15 is provided on the mounting frame 12, and the filter plate 15 is located between the air guide plate 13 and the corrugated pipe 11.

[0036] Specifically, a large amount of dust floats in the electrolytic cell construction environment. When the blower assembly 2 stops working, the adhering dust and large particles of dust will accumulate in the corrugated pipe 11. Over time, the mass will continue to increase, which will damage the moving corrugated pipe 11 and may enter the blower assembly 2. The filter plate 15 blocks the adhering dust and large particles of dust from the outside of the corrugated pipe 11, effectively extending the service life of the corrugated pipe 11 and ensuring the working efficiency of the blower assembly 2.

[0037] See Figure 4 In an exemplary embodiment, the air guide plate 13 is provided with bristles 131 on one side.

[0038] It should be noted that the distance between the air guide plate 13 and the filter plate 15 when they are perpendicular is less than the length of the brush bristles 131.

[0039] Specifically, when the air guide plate 13 rotates, the bristles 131 can come into contact with the filter plate 15. Based on airflow cleaning, the bristles 131 can clean the stubborn dust and hard scale on the filter plate 15 through mechanical contact, forming a synergistic effect with airflow cleaning, effectively ensuring the air volume, and is particularly effective in cleaning adhesive dust that is difficult to be blown away by airflow.

[0040] See Figure 1 In an exemplary embodiment, the blower assembly 2 includes: a connecting box 21, an air supply pipe 22, and a blower 23. The connecting box 21 is disposed at the end of the corrugated pipe 11 away from the mounting frame 12; one end of the air supply pipe 22 is connected to the side of the connecting box 21 away from the corrugated pipe 11; and the air outlet of the blower 23 is connected to the end of the air supply pipe 22 away from the connecting box 21.

[0041] Specifically, the airflow generated by the blower 23 is delivered to the connecting box 21 via the air supply duct 22, and then to the mounting frame 12 via the corrugated pipe 11. The blower 23 provides a continuous and stable airflow source for dust removal, ensuring sufficient air pressure and volume; the air supply duct 22 guides the airflow from the blower 23 to the connecting box 21, enabling long-distance airflow delivery; the connecting box 21 buffers and distributes the airflow, making the airflow entering the corrugated pipe 11 more uniform, avoiding excessively high or low local air pressure, ensuring stable airflow from the air guide plate 13, and improving the stability of the dust removal effect.

[0042] See Figure 1 In an exemplary embodiment, there are several air duct adjustment components 1, which are arranged in an array along the array direction of the air guide plate 13 and are all connected to the connecting box 21.

[0043] Specifically, the connecting box 21 simultaneously supplies airflow to multiple air duct adjustment components 1, and each air duct adjustment component 1 independently adjusts its air guide angle and position. The array arrangement of multiple air duct adjustment components 1 can significantly widen the lateral coverage of dust removal, enabling simultaneous dust removal of multiple anode busbar lifting frames, thereby improving dust removal efficiency and comprehensiveness.

[0044] See Figure 1 In an exemplary embodiment, a plurality of hair dryers 23 and air supply pipes 22 are provided. A plurality of hair dryers 23 are arranged in an array along the array direction of the air duct adjustment component 1, and a plurality of air supply pipes 22 are respectively connected between the hair dryers 23 and the connecting box 21.

[0045] Specifically, multiple blowers 23 simultaneously deliver airflow to the connecting box 21 through their respective air supply pipes 22. The combination of multiple blowers 23 and air supply pipes 22 can significantly improve the total air volume and air pressure, avoid the problem of insufficient airflow caused by excessive load on a single blower 23, provide sufficient power for large-area dust cleaning or removal of stubborn dust accumulation, and at the same time, multi-source air supply can make the airflow distribution in the connecting box 21 more uniform, ensuring the airflow stability of each air duct adjustment component 1.

[0046] See Figure 3 In an exemplary embodiment, a plurality of limiting blocks 144 are provided, and the plurality of limiting blocks 144 are arranged in an array on the rack 142 along the sliding direction of the rack 142 and are threadedly connected to the threaded rod 145.

[0047] Specifically, when the threaded rod 145 rotates, multiple limiting blocks 144 synchronously drive the rack 142 to slide along the limiting groove. The multiple limiting blocks 144 can disperse the driving force on the rack 142, preventing the rack 142 from deforming or deviating due to excessive force at a single point, ensuring the straightness and stability of the rack 142's movement, thereby ensuring the meshing accuracy between the gear 143 and the rack 142, making the angle adjustment of the air guide plate 13 more precise and the synchronization better, and improving the overall transmission reliability of the drive component 14.

[0048] In an exemplary embodiment, the pore size on the filter plate 15 ranges from 0.4 to 1 mm.

[0049] Specifically, the airflow enters the area of ​​the air guide plate 13 through the filter plate 15 with this aperture range. The aperture of 0.4-1mm can effectively intercept impurity particles in the airflow that may damage the equipment, preventing them from adhering to the frame or transmission components, while also reducing airflow resistance and avoiding excessive airflow loss. This balances filtration effect and ventilation efficiency, ensuring the effective airflow required for dust removal.

[0050] In an exemplary embodiment, the drive motor 146 is a servo motor.

[0051] Specifically, the servo motor drives the threaded rod 145 to rotate to adjust the angle of the air guide plate 13. The servo motor has high-precision speed and angle control capabilities, which can accurately control the rotation amount of the threaded rod 145, and then precisely adjust the rotation angle of the air guide plate 13 through the limit block 144, rack 142, and gear 143, thereby improving the accuracy and response speed of air direction adjustment. It can quickly adapt to the dust removal needs of different positions of the anode busbar lifting frame and enhance the control flexibility of the device.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not 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.
