Description

An anode surface cleaning device for aluminum electrolysis Technical Field

[0001] This invention belongs to the field of aluminum electrolysis technology, and particularly relates to an anode surface cleaning device for aluminum electrolysis. Background Technology

[0002] Anode blocks refer to carbon blocks produced using petroleum coke and pitch coke as aggregates and coal tar pitch as binders. They are used as anode materials in prebaked aluminum electrolysis cells. These carbon blocks have been roasted and have a stable geometric shape, so they are also called prebaked anode carbon blocks, or conventionally, carbon anodes for aluminum electrolysis.

[0003] During the production process, anode blocks require cleaning to remove surface deposits. This cleaning is achieved using shot blasting or chain hammer cleaning processes to improve production efficiency. Chinese patent CN218945834U discloses an automatic surface cleaning device for anode steel claws used in aluminum electrolysis. This utility model discloses an automatic surface cleaning device for anode steel claws used in aluminum electrolysis, comprising a frame, a chain-spinning mechanism, a protective cover assembly, and a material recovery trolley. A hopper mounting platform is fixedly installed inside the frame, with the hopper installed on the upper layer inside the frame. The lower layer inside the frame forms a passageway for the material recovery trolley to pass through. The top opening of the hopper connects to the protective cover assembly, forming a relatively enclosed hammering space. The chain-spinning mechanism extends into the hammering space, driving a chain to rotate and hammer the anode steel claws in a vertical plane. The bottom opening of the hopper connects to the material recovery trolley. Compared with existing chain-beating devices, this automatic surface cleaning device for anode steel claws used in aluminum electrolysis uses a different beating method, resulting in better cleaning of iron oxide and attached electrolytes on the surface of the anode steel claws. The cleaned iron oxide and electrolytes can be recycled. However, the above technology has the following problems: using a chain to beat the surface of the anode block results in uneven cleaning or damage to the surface of the anode block. In addition, adjusting the beating force of the chain to ensure the cleaning effect can easily cause breakage, thus reducing the cleaning effect of the anode block. Furthermore, when collecting the cleaned dust, it is not convenient for users to conveniently and directionally discharge the attached materials. When the anode block is enclosed by a sealing cover to form a closed working environment, it is not convenient for users to quickly connect the sealing cover to the anode block for use. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides an anode surface cleaning device for aluminum electrolysis that can overcome or at least partially solve the above problems.

[0005] This invention is implemented as follows: an anode surface cleaning device for aluminum electrolysis includes a cleaning platform, an anode block, a sealing cover, four scrapers, and dust collection holes. The anode block is located at the top of the cleaning platform, and the bottom of the sealing cover is horizontally aligned with the top of the anode block. The four scrapers are located around the perimeter of the inner cavity of the sealing cover and are fixedly connected to the sealing cover. Multiple dust collection holes are evenly distributed on the top of the cleaning platform. A cleaning mechanism that works in conjunction with the anode block is provided on the top of the sealing cover. Lifting mechanisms that work in conjunction with the cleaning mechanism are provided on both the front and rear sides of the cleaning platform. A dust suction mechanism that works in conjunction with the dust collection holes is provided at the bottom of the cleaning platform.

[0006] To improve the cleaning effect of the anode block, preferably, the cleaning mechanism includes a fixed plate, two mounting brackets, a rotary motor, a transmission disc, two gear discs, and three cleaning blocks. The bottom of the fixed plate is fixedly connected to the top of the sealing cover. The two mounting brackets are located at the front and rear sides of the top of the fixed plate, respectively. The front and rear sides of the rotary motor are both fixedly connected to the mounting brackets. The transmission disc is fixedly installed at the output end of the bottom of the rotary motor. The two gear discs are located at the front and rear sides of the top of the fixed plate, respectively. The tops of the three cleaning blocks are fixedly connected to the bottoms of the two gear discs and the transmission disc, respectively. The bottoms of the three cleaning blocks are horizontally aligned with the top of the anode block. By setting up the cleaning mechanism, the rotary motor can quickly clean the surface of the anode block through the cleaning blocks, thereby improving the cleaning effect of the anode block.

[0007] To improve the ease of lifting and lowering the sealing cover, preferably, the lifting mechanism includes a support plate, a cylinder, and a connecting plate. The top of the support plate is fixedly connected to the bottom of the cleaning platform, the bottom of the cylinder is fixedly connected to the top of the support plate, the bottom of the connecting plate is fixedly connected to the output end of the top of the cylinder, and the rear side of the top of the connecting plate is fixedly connected to the bottom of the fixed plate. By setting up the lifting mechanism, the cylinder can quickly move the sealing cover through the cooperation of the connecting plate and the fixed plate, avoiding the problem of not being able to quickly dock the sealing cover with the cleaning platform when it is necessary to adapt the sealing cover to the anode block. Moreover, when the sealing cover is lowered and docked with the anode block through the lifting mechanism, the surface of the anode block can be cleaned by the scraper fixed inside, which also serves as an auxiliary cleaning mechanism.

[0008] To improve the dust collection effect of the cleaning station, preferably, the dust collection mechanism includes a dust collection module, dust collection pipes, and dust collection plates. The top of the dust collection module is fixedly connected to the bottom of the cleaning station. Multiple dust collection pipes are evenly distributed around the dust collection module, and four dust collection plates are evenly distributed around the bottom of the cleaning station. The top of each dust collection pipe is fixedly connected to the bottom of the dust collection plate. By setting up the dust collection mechanism, the dust collection module can quickly absorb and process the dust inside the dust collection plates through the dust collection pipes, avoiding the problem of not being able to conveniently process the dust when it needs to be processed. Furthermore, through the cooperation of multiple dust collection pipes, efficient absorption and processing of dust falling from various directions can be achieved.

[0009] To improve the material discharge effect of the dust collection mechanism, preferably, a material discharge protective cover is fixedly connected to the bottom of the cleaning table, and a material discharge port is fixedly connected to the bottom of the dust collection module. The bottom of the material discharge protective cover is horizontally aligned with the bottom of the material discharge port, and a dust collection box is movably connected to the bottom of the material discharge protective cover. The top of the dust collection box is horizontally aligned with the bottom of the material discharge port. By setting up the material discharge protective cover, the material discharge port, and the dust collection box, and ensuring that the openings of the material discharge protective cover, the material discharge port, and the dust collection box are horizontally aligned, the material discharge port can guide the dust to the inner cavity of the dust collection box when discharging dust, thus protecting the surrounding working environment.

[0010] To improve the ease of use of the cleaning mechanism, preferably, the bottom of the mounting frame is fixedly connected to the top of the fixed plate, and the top of the toothed disc is fixedly connected to the bottom of the mounting frame via a rotating shaft. The opposite ends of the two toothed discs are meshed with the surface of the transmission disc. By setting up the mounting frame, transmission disc, and toothed disc, the transmission disc drives the toothed disc and cleaning block to rotate through the meshing connection with the toothed disc during rotation. The bottom of the mounting frame and the top of the toothed disc are movably connected via a rotating shaft to ensure the stability of the toothed disc during rotation.

[0011] To improve the cleaning effect of the cleaning block, preferably, the surface of the cleaning block is fixedly connected with protrusions. The number of protrusions is multiple and they are distributed in a ring on the surface of the cleaning block. The bottom of the four scrapers is horizontally aligned with the top of the anode block. By setting the protrusions and distributing them in a ring on the surface of the cleaning block, they can better fit the surface of the anode block, thereby improving the cleaning effect of the cleaning block and avoiding the situation where the four corners of the cleaning block cannot clean the fine parts of the anode block.

[0012] To improve the compatibility between the dust collection mechanism and the dust outlet, preferably, the top of the dust collection plate is horizontally aligned with the bottom of the dust outlet, and the bottom of the sealing cover is horizontally aligned with the top of the dust outlet. The dust outlet and the dust collection plate are used for dust discharge, and the sealing cover is used to prevent dust splashing. By setting the dust outlet, dust collection plate, and sealing cover, and ensuring that the bottom of the sealing cover is stably attached to the top of the cleaning table, the anode block can be sealed. Therefore, the cleaned dust can enter the inner cavity of the dust collection plate through the dust outlet, thus improving the dust collection effect of the dust collection mechanism.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] This invention comprises a cleaning platform, an anode block, a sealing cover, a scraper, a dust collection hole, a cleaning mechanism, a lifting mechanism, and a dust extraction mechanism. When cleaning of the anode block is required, a cylinder is activated. During the cylinder's retraction, a connecting plate moves a fixed plate. As the fixed plate moves, it causes the sealing cover and cleaning mechanism to align with the anode block. When the sealing cover and cleaning platform are in contact, a closed working space is formed, facilitating the use of the cleaning mechanism. Furthermore, as the scraper descends with the sealing cover, it stably cleans the area around the anode block. The attachments are cleaned, and during the cleaning of the anode block, the scraper causes dust to pass through the inner cavity of the dust hole and fall onto the surface of the dust collection plate. After docking, the cleaning block of the cleaning mechanism is inserted into the groove at the top of the anode block. After the insertion is completed, the rotary motor is started. The rotary motor drives the bottom cleaning block and the transmission disc to rotate through its output end. During the rotation of the transmission disc, it drives the toothed disc and the other two cleaning blocks to rotate through the meshing connection with the toothed disc. During the rotation of all three cleaning blocks, the protrusion block will also rotate, thus achieving simultaneous cleaning of the anode block. The inner walls of the three grooves at the top of the anode block are cleaned, thus improving the cleaning effect of the anode block. During the cleaning process, the dust collection module can be activated. During operation, the dust collection module can quickly handle the dust through the cooperation of the dust collection pipe, dust collection plate, and dust discharge hole. The dust collection module can achieve directional discharge through the cooperation of the discharge port and the discharge protective cover. The bottom of the dust collection box and the discharge protective cover are connected to achieve a stable material receiving effect. Therefore, the lifting and lowering of the sealing cover is convenient, the cleaning effect of the anode block is improved, and the dust treatment effect after the anode block is improved. This solves the problems of uneven cleaning effect or damage to the surface of the anode block caused by using a chain to beat the surface of the anode block. In addition, adjusting the chain beating force to ensure the cleaning effect of the chain can easily cause breakage, thus reducing the cleaning effect of the anode block. Furthermore, when collecting the dust after cleaning, it is not convenient for the user to conveniently discharge the attached material in a directional manner. When the sealing cover creates a closed working environment for the anode block, it is not convenient for the user to quickly move the sealing cover and the anode block for use.

[0024] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

A dust suction mechanism 8 for use with the dust collection holes 5 is provided on the bottom of the cleaning platform 1. The cleaning mechanism 6 includes... The system comprises a fixed plate 601, two mounting brackets 602, a rotary motor 603, a transmission disc 604, two gear discs 605, and three cleaning blocks 606. The bottom of the fixed plate 601 is fixedly connected to the top of the sealing cover 3. The two mounting brackets 602 are located at the front and rear sides of the top of the fixed plate 601, respectively. The front and rear sides of the rotary motor 603 are fixedly connected to the mounting brackets 602. The transmission disc 604 is fixedly installed at the output end of the bottom of the rotary motor 603. The two gear discs 605 are located at the front and rear sides of the top of the fixed plate 601, respectively. The tops of the three cleaning blocks 606 are fixedly connected to the bottoms of the two gear discs 605 and the transmission disc 604, respectively. The bottoms of the three cleaning blocks 606 are horizontally aligned with the top of the anode block 2. This cleaning mechanism 6... The rotary motor 603 enables rapid cleaning of the surface of the anode block 2 via the cleaning block 606, thereby improving the cleaning effect of the anode block 2. The lifting mechanism 7 includes a support plate 701, a cylinder 702, and a connecting plate 703. The top of the support plate 701 is fixedly connected to the bottom of the cleaning table 1, the bottom of the cylinder 702 is fixedly connected to the top of the support plate 701, the bottom of the connecting plate 703 is fixedly connected to the output end of the top of the cylinder 702, and the rear side of the top of the connecting plate 703 is fixedly connected to the bottom of the fixed plate 601. By setting up the lifting mechanism 7, the cylinder 702 can quickly move the sealing cover 3 through the cooperation of the connecting plate 703 and the fixed plate 601, avoiding the need for... When the sealing cover 3 is used in conjunction with the anode block 2, there is a problem that the sealing cover 3 cannot be quickly docked with the cleaning table 1. Furthermore, when the sealing cover 3 is lowered and docked with the anode block 2 via the lifting mechanism 7, it can clean the surface of the anode block 2 around its perimeter using a scraper 4 fixed inside, thus assisting the cleaning mechanism 6. The dust collection mechanism 8 includes a dust collection module 801, dust collection pipes 802, and dust collection plates 803. The top of the dust collection module 801 is fixedly connected to the bottom of the cleaning table 1. Multiple dust collection pipes 802 are evenly distributed around the dust collection module 801. Four dust collection plates 803 are evenly distributed around the bottom of the cleaning table 1. The top of the dust collection pipes 802 is fixedly connected to the bottom of the dust collection plates 803.By setting up a dust collection mechanism 8, the dust collection module 801 can quickly absorb and process the dust inside the dust collection plate through the dust collection pipe 802, avoiding the problem of not being able to conveniently process the dust when it needs to be cleaned. Furthermore, through the cooperation of multiple dust collection pipes 802, it can efficiently absorb and process dust falling from various directions. A discharge protective cover 9 is fixedly connected to the bottom of the cleaning table 1, and a discharge port 10 is fixedly connected to the bottom of the dust collection module 801. The bottom of the discharge protective cover 9 is horizontally aligned with the bottom of the discharge port 10. A dust collection box 11 is movably connected to the bottom of the discharge protective cover 9. The top and bottom of the discharge port 10 are horizontally aligned. By setting up a discharge protective cover 9, a discharge port 10, and a dust collection box 11, the openings of the discharge protective cover 9, the discharge port 10, and the dust collection box 11 are horizontally aligned. Therefore, when the discharge port 10 discharges dust, the discharge protective cover 9 guides the dust to the inner cavity of the dust collection box 11, thus protecting the surrounding working environment. The bottom of the mounting bracket 602 is fixedly connected to the top of the fixing plate 601. The top of the gear disc 605 is fixedly connected to the bottom of the mounting bracket 602 via a rotating shaft. The opposite ends of the two gear discs 605 are meshed with the surface of the transmission disc 604. By setting up the mounting bracket 602, the transmission... The drive disc 604 rotates, driving the gear disc 605 and cleaning block 606 to rotate through the meshing connection with the gear disc 605. The bottom of the mounting bracket 602 is movably connected to the top of the gear disc 605 via a rotating shaft, ensuring the stability of the gear disc 605 during rotation. Multiple protrusions 12 are fixedly connected to the surface of the cleaning block 606, arranged in a ring. The bottoms of the four scrapers 4 are horizontally aligned with the top of the anode block 2. By setting the protrusions 12, which are arranged in a ring on the surface of the cleaning block 606, better contact with the surface of the anode block 2 is achieved, thereby improving the cleaning efficiency. To improve the cleaning effect of the cleaning block 606 and avoid situations where the corners of the cleaning block 606 cannot clean the fine parts of the anode block 2, the top of the dust collection plate 803 is horizontally aligned with the bottom of the dust outlet 5, and the bottom of the sealing cover 3 is horizontally aligned with the top of the dust outlet 5. The dust outlet 5 and the dust collection plate 803 are used for dust discharge, and the sealing cover 3 is used to prevent dust splashing. By setting up the dust outlet 5, the dust collection plate 803, and the sealing cover 3, and ensuring that the bottom of the sealing cover 3 is stably attached to the top of the cleaning table 1, the anode block 2 can be sealed. Therefore, the cleaned dust can enter the inner cavity of the dust collection plate 803 through the dust outlet 5, thus improving the dust collection effect of the dust collection mechanism 8.

[0026] Working principle of the invention:

[0027] When cleaning of anode block 2 is required, cylinder 702 is activated. During the retraction of cylinder 702, the fixed plate 601 moves via connecting plate 703. As the fixed plate 601 moves, it aligns the sealing cover 3 and cleaning mechanism 6 with anode block 2. When the sealing cover 3 and cleaning table 1 are in contact, a closed working space is formed through their cooperation, facilitating the use of cleaning mechanism 6. As scraper 4 descends with the sealing cover 3, it steadily cleans the deposits around anode block 2. During cleaning, the scraper 4 causes dust to pass through the inner cavity of the dust hole 5 and fall onto the surface of dust collection plate 803. After alignment, cleaning block 606 of cleaning mechanism 6 is inserted into the groove at the top of anode block 2. After insertion, rotary motor 603 is activated. Rotary motor 603 drives the bottom cleaning block 606 and transmission disc 604 to rotate via its output end. During rotation, the transmission disc 604, through its meshing connection with the gear disc 605, drives the gear disc 605 and the other two cleaning blocks 606 to rotate as well. The rotation of all three cleaning blocks 606 also drives the protrusion 12 to rotate, thus simultaneously cleaning the inner walls of the three grooves on the top of the anode block 2, thereby improving the cleaning effect of the anode block 2. During the cleaning of the anode block 2, the dust collection module 801 can be activated. During operation, the dust collection module 801, through the cooperation of the dust collection pipe 802, the dust collection plate 803, and the dust discharge hole 5, can quickly process the cleaning dust. Furthermore, the dust collection module 801 can achieve directional discharge through the cooperation of the discharge port 10 and the discharge protective cover 9. The dust collection box 11, connected to the bottom of the discharge protective cover, achieves stable material receiving. Therefore, the lifting and lowering of the sealing cover 3 is convenient, the cleaning effect of the anode block 2 is achieved, and the dust treatment effect after cleaning the anode block 2 is achieved.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can exercise their rights without departing from the scope of the present invention.
