Description

Technical Field

[0001] This application belongs to the technical field of supporting equipment for electrolytic aluminum production, and in particular relates to a device and method for cleaning carbon blocks. Background Technology

[0002] In aluminum electrolysis, the anode carbon block, as the core carrier of the electrochemical reaction, is a key component for aluminum ion reduction in the electrolytic cell, directly affecting electrolysis efficiency, current efficiency, and production costs. It is primarily a block-shaped object made of high-purity graphite or other carbon materials, ensuring excellent electrical conductivity, high-temperature oxidation resistance, and mechanical strength. To meet the connection requirements of the guide rod during anode assembly, 2-4 uniformly sized circular grooves, commonly known as carbon bowls, are cut into the upper surface of the carbon block in the conductive direction. The groove walls must be kept flat to avoid affecting the contact stability between the steel claws and the carbon block due to dimensional deviations. In the anode carbon block production process, the freshly formed anode carbon block needs to be rapidly cooled immediately by water spraying or immersion. This step not only shortens the production cycle but also prevents the carbon block from cracking and producing defective products by precisely controlling the cooling rate. However, water easily accumulates inside the cooled carbon bowls. If not cleaned in time, this can lead to a significant increase in the scrap rate during the subsequent anode roasting process.

[0003] Currently, the domestic aluminum industry generally uses compressed air purging to clean water accumulated in the carbon bowl. Although this process is simple to operate, it is not very effective and water residue is easily left behind. In order to improve the cleaning effect, the compressed air pressure has to be increased, which can easily cause noise, mist, water splashes, etc. If the mist and water splashes enter the electrical and mechanical components, they can easily damage the components. At the same time, there is a safety hazard of fire caused by electrical short circuits.

[0004] Therefore, developing a new method for cleaning water accumulation in the carbon bowl is of great significance for improving the stability and economic benefits of aluminum electrolysis production. Summary of the Invention

[0005] This application discloses a device and method for cleaning charcoal blocks, aiming to solve the technical problems of high noise, high cost and poor cleaning effect when cleaning water accumulation in the charcoal bowl of existing charcoal blocks.

[0006] To achieve the above objectives, the technical solution of this application is: The first aspect of this application provides a device for cleaning charcoal blocks, comprising: A frame, the frame including a conveying device for conveying charcoal blocks having charcoal bowls; A cleaning device is installed on the frame and located at the cleaning station. The cleaning device includes a telescopic drive assembly and at least one water-absorbing element. The water-absorbing element is located at the telescopic end of the telescopic drive assembly. The telescopic drive assembly can drive the water-absorbing element to extend into and be pressed into the charcoal bowl. After releasing the pressure on the water-absorbing element to allow it to absorb water from the charcoal bowl, the assembly drives the water-absorbing element to move out of the charcoal bowl.

[0007] In conjunction with the first aspect, preferably, the telescopic drive assembly includes: a drive component and a mounting frame; the drive component is connected to the mounting frame; The driving component includes a cylinder body and a guide rod. One end of the guide rod is fixedly connected to the piston rod of the cylinder body, and the other end is detachably connected to the water-absorbing component. The guide rod moves along a direction perpendicular to the carbon block transmission direction and is coaxially linked with the cylinder body. The mounting bracket is installed on the frame.

[0008] In conjunction with the first aspect, preferably, the frame includes: an adjustable frame and a support frame, and the mounting bracket is mounted on the adjustable frame; The vertical adjustment frame is located on the upper part of the support frame, and the height of the vertical adjustment frame is adjustable.

[0009] Preferably, in conjunction with the first aspect, the conveying device is provided with a track; At least one set of rollers is vertically arranged on the track, and the rollers are rotatably connected to the frame.

[0010] In conjunction with the first aspect, preferably, the absorbent component is one of an absorbent sponge or an absorbent resin composite material, and the shape of the absorbent component is adapted to the shape of the inner wall of the charcoal bowl.

[0011] In conjunction with the first aspect, preferably, the cleaning device further includes: A retainer is provided on the conveying device for fixing the position of the carbon block.

[0012] The second aspect of this application provides a method for cleaning charcoal lumps, implemented using the charcoal lumps cleaning apparatus described in the first aspect, the method comprising: The charcoal blocks to be cleaned are transported to the cleaning station via a conveyor. When the telescopic drive assembly is activated, it moves downwards, and the water-absorbing part at the end extends into the carbon bowl of the carbon block. After being compressed, it squeezes out the same volume of water from inside the carbon bowl. After the water is squeezed out, the telescopic drive component moves upward, and the water-absorbing component absorbs the remaining water inside the carbon block and carbon bowl during the process of restoring its deformation.

[0013] Preferably, in conjunction with the second aspect, the downward speed of the telescopic drive assembly is 50-80 mm / s.

[0014] In conjunction with the second aspect, preferably, the compression amount of the water-absorbing element extending into the charcoal bowl is 15%-25% of the initial volume of the water-absorbing element.

[0015] Compared with the prior art, the advantages or beneficial effects of the embodiments of this application include at least the following: The carbon block cleaning device provided in this application cleans the water inside the carbon bowl by transferring the carbon block to a positioning area, where a telescopic drive assembly drives a water-absorbing component to extend into and be pressed against the inner surface of the carbon bowl. This significantly reduces operating noise to below 25 dB, improving the working environment. Furthermore, the water-absorbing cleaning method not only cleans more thoroughly but also effectively solves the problem of traditional air-blowing methods failing to remove accumulated water from the carbon bowl, which can lead to cracking of the anode carbon block. Simultaneously, the device enables continuous cleaning operations, further improving overall production efficiency. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] In the following description of this embodiment, the term "at least one" means one or more, and "more than one" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or multiple items.

Some or all steps may be executed in parallel or sequentially. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0021] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms "a" and "the" as used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0022] It should be noted that all raw materials and / or reagents in the embodiments of this application were purchased on the market or prepared according to conventional methods known to those skilled in the art.

[0023] This application provides a schematic diagram of a charcoal block cleaning device, as shown in the embodiment. Figure 1-4 As shown: The frame 1 includes a conveying device 11 for conveying charcoal blocks 3 with charcoal bowls; the frame 1 also includes an adjustable frame 12 and a support frame 13, the adjustable frame 12 being located above the support frame 13 and capable of reciprocating adjustment in the vertical direction. The support frame 13 supports the entire device.

[0024] The cleaning device 2 includes a telescopic drive assembly 21 and a water-absorbing component 22. The telescopic drive assembly 21 consists of a drive component 211 and a mounting bracket 212. The drive component 211 includes a cylinder body 2111 and a guide rod 2112. The cylinder body 2111 provides the telescopic power, and the guide rod 2112 ensures the linearity and stability of the telescopic movement. The mounting bracket 212 is used to fix the water-absorbing component 22, allowing it to reciprocate under the drive of the drive component 211. Driven by the telescopic drive assembly 21, the water-absorbing component 22 can extend into the charcoal bowl of the charcoal block 3 and be pressed tightly, achieving efficient adsorption and cleaning of water within the charcoal bowl through its own water absorption properties.

[0025] Specifically, the conveying device 11 is equipped with a track for conveying charcoal blocks 3. At least one set of rollers 111 are arranged on the track perpendicular to the conveying direction of charcoal blocks 3. Each set of rollers 111 is rotatably connected to the frame 1 via rolling bearings. The rollers 111 can rotate flexibly according to the conveying requirements of charcoal blocks 3. Driven by the power of the conveying device, they can drive the charcoal blocks 3 to be smoothly and continuously conveyed along the track to the positioning area of ​​the cleaning operation, and convey the cleaned charcoal blocks 3 to the next process. At the same time, the connection method of rolling bearings effectively reduces the frictional resistance between the rollers 111 and the frame 1, which not only improves the smoothness of charcoal block 3 conveying, but also extends the service life of the device, laying a reliable material conveying foundation for the continuous cleaning operation of the charcoal bowl water of charcoal blocks 3.

[0026] Specifically, the up-down adjustment frame 12 includes an outer frame 121 and an inner frame 122. The inner frame 122 is slidably sleeved inside the outer frame 121. The outer frame 121 is provided with a positioning hole 123, and the inner frame 122 is provided with a positioning pin 124 that matches the positioning hole 123. Up-down adjustment and positioning are achieved by inserting the positioning pin 124 into the positioning hole 123 at different heights.

[0027] Specifically, the driving component 211 includes a cylinder body 2111 and a guide rod 2112, and also includes a guide sleeve 2113. The guide sleeve 2113 is fixedly mounted on the upper and lower adjusting frame 12, and the guide rod 2112 slides through the inside of the guide sleeve 2113. The inner wall of the guide sleeve 2113 is provided with a wear-resistant coating, which is a polytetrafluoroethylene coating or a ceramic coating.

[0028] Specifically, the absorbent component 22 is preferably one of an absorbent sponge or an absorbent resin composite material, and its shape is adapted to the inner wall shape of the charcoal bowl. The absorbent sponge, with its porous and loose structure, possesses excellent instantaneous water absorption and storage capacity; the absorbent resin composite material, due to its highly absorbent molecular structure, can achieve efficient adsorption and retention of water. Furthermore, the shape of the absorbent component 22 is designed to closely match the inner wall shape of the charcoal bowl. When the absorbent component 22 extends into the charcoal bowl under the action of the telescopic drive assembly, it can fit closely to the inner wall of the charcoal bowl, ensuring both thorough drainage through squeezing and efficient adsorption of residual water through full contact. This combination of material properties and structural compatibility ensures effective cleaning of the water inside the charcoal bowl.

[0029] Specifically, for charcoal bowls with different inner diameters, the material or shape of the water-absorbing component 22 can be adjusted to match the inner diameter of the charcoal bowl within the charcoal block 3. During operation, the water-absorbing component 22 extends into the charcoal bowl under the action of the telescopic drive assembly and is squeezed and deformed. On the one hand, it directly squeezes out the water accumulated inside the charcoal bowl; on the other hand, during its recovery process, it absorbs and stores the residual water inside the charcoal bowl of the green anode charcoal block, thereby ensuring the thorough cleaning of the water inside the charcoal bowl. In other words, the material selection and shape design of the water-absorbing component 22 in this application are adjustable, and it can adapt to charcoal bowls with various inner diameters, greatly improving the versatility of the charcoal bowl cleaning device and meeting the charcoal block cleaning needs under different working conditions.

[0030] Specifically, the cleaning device 2 also includes a retainer 23; the retainer 23 is mounted on the conveying device and is used to fix the position of the charcoal block 3. It employs a mechanical clamping or positioning pin structure. When the charcoal block 3 is conveyed to the cleaning area, the retainer 24 can securely limit its position from the side or bottom of the charcoal block, ensuring that the charcoal block remains absolutely stationary during the insertion and squeezing process of the absorbent 22. This prevents situations such as poor adhesion between the absorbent 22 and the charcoal bowl due to charcoal block displacement, resulting in cleaning failure, and ensures the stability of the cleaning operation.

[0031] Specifically, the conveying device is equipped with a limit detector to detect the position coordinates of the charcoal bowl. This ensures that the water-absorbing component 22 can accurately and without deviation extend into the charcoal bowl, providing precise spatial positioning for subsequent water cleaning operations and effectively avoiding incomplete cleaning caused by charcoal bowl misalignment.

[0032] Specifically, the cleaning device also includes a control module, which is electrically connected to both the conveying device and the telescopic drive assembly. The control module controls the start and stop of the conveying device and the extension / retraction stroke of the telescopic drive assembly. The control module operates as follows: upon receiving the arrival signal of the carbon block, it immediately stops the conveying device and simultaneously controls the telescopic drive assembly to extend according to preset parameters, driving the absorbent component into the carbon bowl and pressing it firmly. These preset parameters include the extension stroke, extension speed, pressing and holding time, and retraction speed of the telescopic drive assembly, ensuring that the absorbent component fully absorbs the water from the carbon bowl. When the pressing and holding time reaches the preset value, the control module controls the telescopic drive assembly to retract in the opposite direction. After the absorbent component is completely removed from the carbon bowl, the control module delays for 0.5-2 seconds before restarting the conveying device, removing the cleaned carbon block from the cleaning station, and conveying the next carbon block to be cleaned.

[0033] The working process of this application is as follows: After the green anode carbon block 3 to be cleaned is conveyed by the conveying device 11 to the designated position of the carbon block cleaning device, the conveying device 11 stops working after the carbon block 3 is in place. The fixing device 23 on the conveying device is activated to firmly fix the carbon block and ensure that the carbon block does not shift in subsequent operations. The telescopic drive assembly 21 starts: the cylinder body 2111 of the drive component 211 provides power, the guide rod 2112 ensures the accuracy of linear motion, and drives the mounting frame 212 and the water suction component 22 on the frame to accurately extend and retract, so that the water suction component 22 accurately extends into the carbon bowl along the coordinate trajectory of the carbon bowl. After the water suction component 22 is fully extended, the telescopic drive assembly 21 continuously applies pressure, so that the water suction component 22 is tightly attached to the inner wall of the carbon bowl in all directions and is squeezed and deformed. After cleaning, the telescopic drive assembly 21 drives the water-absorbing component 22 to exit from the charcoal bowl, the retainer 23 releases the charcoal block 3 from the fixing, the conveying device 11 starts, and transports the cleaned charcoal block out of the cleaning area; at the same time, a new charcoal block to be cleaned is transported to the cleaning position, and the above work process is repeated to achieve continuous operation.

[0034] Specifically, the downward speed of the telescopic drive assembly is preferably 50-80 mm / s. By controlling the downward speed, the extrusion pressure can be applied gradually, ensuring that the water-absorbing component 22 deforms uniformly and achieves a tight fit with the inner wall of the charcoal bowl. If the speed is too fast, the water-absorbing component may experience uneven local stress due to instantaneous extrusion, resulting in gaps in the fit and affecting the water extrusion effect; if the speed is too slow, the extrusion process will be sluggish, reducing the overall cleaning efficiency.

[0035] Specifically, the compression of the absorbent component extending into the charcoal bowl is 15%-25% of its initial volume. This ensures sufficient compressive contact force between the absorbent component and the inner wall of the charcoal bowl, while also preserving ample space for deformation recovery.
