Description

Technical Field

[0001] This application relates to the field of anode carbon block processing technology, specifically to a surface cleaning system for anode carbon blocks. Background Technology

[0002] Anode carbon blocks are common anode reaction components in the current field of electrolytic aluminum production. They are made of pressed carbon powder and are mostly rectangular in structure. One surface has a cylindrical sink, commonly called a carbon bowl, which is used to mount the anode steel claw (a component used for transmitting electricity). When installing the anode steel claw, it is essential to ensure that the carbon bowl is free of impurities and kept clean; otherwise, the stability of the connection between the anode steel claw and the carbon bowl will be affected. Currently, during the transport of anode carbon blocks, a blowing device is used to blow out impurities from the carbon bowl to remove them. However, this method of impurity removal results in the workshop being filled with carbon powder dust. This dust not only settles on other anode carbon blocks but is also easily inhaled by workshop operators, affecting their health. Summary of the Invention

[0003] This utility model provides a surface cleaning system for anode carbon blocks, which solves the technical problem of insufficient practicality of existing carbon bowl cleaning equipment in the anode carbon block processing process.

[0004] Specifically, this utility model discloses a surface cleaning system for anode carbon blocks, including a controller and a dust removal device, as well as two sets of roller transport mechanisms, a belt conveyor mechanism disposed between the two sets of roller transport mechanisms, and positioning mechanisms disposed at both ends of the belt conveyor mechanism; the dust removal device includes a dust suction hood corresponding to the number of carbon bowls and a filter tube assembly containing a fan, the dust suction hood including an accordion-type suction tongue; the positioning mechanism includes an H-shaped gripper, a drive motor, and a photoelectric detection component, the piston rod of the drive motor being connected to the geometric center of the H-shaped gripper, the controller controlling the movement of the belt conveyor mechanism based on the detection information of the photoelectric detection component; the belt conveyor mechanism includes a conveyor belt and a flipping mechanism passing through the middle of the conveyor belt.

[0005] The cleaning system of this invention, after the anode carbon block is conveyed onto the conveyor belt, has positioning mechanisms at both ends pushing the anode carbon block to a preset position. Then, a dust removal device above this position uses its suction hood to draw impurities from the carbon bowl on the anode carbon block into the suction hood point-to-point. The impurities are then filtered through a filter tube assembly for easy reuse of the removed carbon powder. The positioning mechanism detects the position of the anode carbon block and feeds feedback to the controller, which then controls the conveyor belt to work with the H-shaped grippers to transport the anode carbon block to the preset position. This system comprehensively realizes the conveying, positioning, cleaning, and transfer of anode carbon blocks, streamlining and automating the anode carbon block conveying and cleaning process. It eliminates the need for existing blowing dust removal methods, prevents dust from shrouding the workshop, and improves the practicality of anode carbon block dust removal.

[0006] Optionally, the flipping mechanism includes: a main shaft and a secondary shaft controlled by a motor for rotation, a first connecting rod fixedly sleeved with the main shaft, and a second connecting rod connected to the secondary shaft. The main shaft and the secondary shaft are connected by a roller bearing, and the first connecting rod and the second connecting rod are 180° and 90° apart.

[0007] In this design, the aforementioned flipping mechanism is used to flip the anode carbon block 90° after cleaning the carbon bowl, so that the surface of the anode carbon block opposite to the carbon bowl is flipped to a vertical position, which facilitates the subsequent removal of carbon powder attached to the surface and further improves the practicality of the cleaning system.

[0008] Optionally, a slide rail is provided above the roller transport mechanism behind the conveying mechanism, and a slider with a scraper is slidably connected to the slide rail. A cylinder controls the slider to move back and forth along the slide rail.

[0009] In this design, after the anode carbon block is cleaned by the dust removal device, when the anode carbon block enters the next section of the roller transport mechanism, a scraper that can reciprocate along the extension direction of the roller is set on the roller transport mechanism. The scraper is used to remove the carbon powder deposited on the bottom surface of the anode carbon block after it has been turned over, so as to perform a more comprehensive cleaning of the surface of the anode carbon block and further improve the practicality of the cleaning system.

[0010] Optionally, the filter tube assembly may further include a settling chamber, which includes a capillary spray tube for automatic water discharge, and the controller is connected to the water pump of the capillary spray tube via a signal connection.

[0011] In this design, the dust removal device filters the impurities that are drawn in through the filter tube assembly. The carbon powder that has passed through the filter tube assembly is then drawn into the settling chamber. The capillary spray pipes installed in the settling chamber help the suspended carbon powder settle. After a period of settling, the mixture containing carbon powder and water can be further separated into solid and liquid components. The dried carbon powder can then be recycled. This not only improves the practicality of the cleaning system but also saves energy and effectively reduces production costs.

[0012] Optionally, the filter assembly includes a cylindrical outer casing and multiple filter screens with different porosities disposed inside the outer casing, wherein the cylindrical outer casing is installed at an angle relative to the ground.

[0013] In this design, the aforementioned filter assembly adopts a cylindrical outer casing. Filter screens with different porosities are installed inside the outer casing to separate impurities of different sizes, which helps to improve the filtration quality of impurities. The purpose of the inclined installation of the cylindrical outer casing is to allow the separated impurities to slide down into the different slag outlets set on the cylindrical outer casing under their own gravity.

[0014] Optionally, the system includes two sets of horizontally parallel and synchronously controlled flipping mechanisms.

[0015] In this design, the flipping mechanism located below the conveyor belt in the belt conveyor mechanism is set into two sets to be compatible with anode carbon blocks of different specifications. The torque of a single set of flipping mechanism is limited, so the weight of the anode carbon blocks it can support is limited. Therefore, setting two sets can improve the load-bearing capacity of the flipping mechanism, thereby being compatible with anode carbon blocks of various weight specifications, and further improving the practicality of the cleaning system.

[0016] Optionally, the blade of the scraper is a flexible plate, and the blade is used for an interference fit on the surface of the anode carbon block.

[0017] In this design, the scraper used to clean the bottom surface of the flipped anode carbon block is designed as a flexible plate to protect the bottom surface of the anode carbon block from excessive wear by the scraper. The flexible plate is press-fitted with the bottom surface of the anode carbon block, thereby removing the carbon powder deposited on the bottom surface of the anode carbon block while protecting the bottom surface from excessive wear by the scraper.

[0018] Optionally, the scraper comprises two sets arranged perpendicular to each other.

[0019] In this design, the aforementioned scraper includes two sets arranged vertically and spaced apart. Different interference fits can be set to achieve the step-by-step scraping of carbon powder deposited on the bottom surface, further improving the practicality of the cleaning system.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] This utility model provides a surface cleaning system for anode carbon blocks, which realizes the transmission, positioning, cleaning and transfer of anode carbon blocks, streamlines and automates the transmission and cleaning process of anode carbon blocks, eliminates the need for existing blowing dust removal, avoids the workshop being covered by dust, and improves the practicality of anode carbon block dust removal.

Detailed Implementation

[0028] The technical solutions in the embodiments of the application will now be clearly and completely described with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in one embodiment" appearing throughout this specification do not necessarily refer to the same embodiment. Moreover, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0029] Anode carbon blocks are common anode reaction components in the existing electrolytic aluminum industry. They are made of pressed carbon powder and are mostly rectangular in structure. One surface has a cylindrical sink, commonly called a carbon bowl, which is used to mount the anode steel claw (a component used for transmitting electricity). When installing the anode steel claw, it is necessary to ensure that the carbon bowl is free of impurities and kept clean; otherwise, the stability of the connection between the anode steel claw and the carbon bowl will be affected. Currently, during the transport of anode carbon blocks, a blowing device is used to blow out impurities from the carbon bowl to remove them. However, this method results in the workshop being filled with carbon powder dust. This dust not only settles on other anode carbon blocks but is also easily inhaled by workshop operators, affecting their health. Therefore, this invention provides a surface cleaning system for anode carbon blocks.

[0030] This utility model discloses a surface cleaning system for anode carbon blocks, including a controller and a dust removal device, as well as two sets of roller transport mechanisms 1, a belt conveyor mechanism 2 disposed between the two sets of roller transport mechanisms 1, and positioning mechanisms 3 disposed at both ends of the belt conveyor mechanism 2; the dust removal device includes a dust suction hood 41 corresponding to the number of carbon bowls and a filter tube assembly 42 containing a fan, the dust suction hood 41 including an accordion-type suction tongue 5; the positioning mechanism 3 includes an H-shaped gripper, a drive motor, and a photoelectric detection component, the piston rod of the drive motor is connected to the geometric center of the H-shaped gripper, and the controller controls the movement of the belt conveyor mechanism 2 according to the detection information of the photoelectric detection component; the belt conveyor mechanism 2 includes a conveyor belt and a flipping mechanism 6 passing through the middle of the conveyor belt.

[0031] Reference Figure 1 and Figure 2 As shown, the cleaning system of this utility model includes a roller transport mechanism 1 on the left, a roller transport mechanism 1 on the right, and a belt transport mechanism 2 located between the left and right roller transport mechanisms 1. The roller transport mechanism 1 includes several rollers arranged side-by-side and spaced apart. Driven by a drive device, the rollers rotate around their own axes, thereby transporting the anode carbon blocks placed on their surfaces forward. The belt transport mechanism 2 uses a motor to drive a conveyor belt or transmission belt, moving and conveying the anode carbon blocks on its surface.

[0032] Specifically, in this embodiment, after the anode carbon block is conveyed onto the conveyor belt of the conveyor mechanism 2, the positioning mechanisms 3 at both ends push the anode carbon block to a preset position. The dust removal device above this position uses its suction hood 41 to suck impurities from the carbon bowl on the anode carbon block into the suction hood 41 point-to-point. The impurities are then filtered through the filter tube assembly 42 for easy reuse of the carbon powder. Additionally, the photoelectric detection component in the positioning mechanism 3 detects the position of the anode carbon block and feeds it back to the controller. The controller then controls the conveyor belt, in conjunction with the H-shaped gripper, to convey the anode carbon block to the preset position, achieving accurate positioning of the anode carbon block and preventing misalignment between the suction hood 41 and the carbon bowl of the anode carbon block when the suction hood 41 descends for suction. Furthermore, the aforementioned suction tongue 5 is used to compress the material so that it completely adheres to the side surface of the carbon bowl on the anode carbon block, preventing impurities from flowing out of the gaps and also preventing air leakage when suctioning impurities.

[0033] As can be seen from the above, this utility model realizes the transmission, positioning, cleaning and transfer of anode carbon blocks, streamlines and automates the transmission and cleaning process of anode carbon blocks, eliminates the need for existing blowing dust removal, avoids the workshop being covered by dust, and improves the practicality of anode carbon block dust removal.

[0034] It should be noted that the flipping mechanism 6 in the foregoing embodiment may include: a main shaft 61 and a secondary shaft 62 controlled by a motor, a first connecting rod 63 fixedly sleeved with the main shaft 61, and a second connecting rod 64 connected with the secondary shaft 62. The main shaft 61 and the secondary shaft 62 are connected by a roller bearing, and the first connecting rod 63 and the second connecting rod 64 are 180° and 90° apart.

[0035] In this embodiment, since the anode carbon blocks are stacked after processing, a layer of carbon powder is usually laid between adjacent anode carbon blocks during stacking to avoid damage or adhesion between them. Alternatively, during handling in the workshop, a layer of carbon powder may adhere to the bottom surface of the anode carbon blocks. To increase the practicality of this invention, the following is provided: Figure 3 The flipping mechanism 6 shown is used to flip the anode carbon block 90° after the carbon bowl has been cleaned, so that the surface of the anode carbon block opposite to the carbon bowl is flipped to a vertical position, which facilitates the subsequent removal of carbon powder adhering to the surface and further improves the practicality of the cleaning system. The main shaft 61 and the auxiliary shaft 62 are connected by roller bearings, so that the two can rotate relative to each other without interference.

[0036] It should be noted that, in this embodiment, the flipping mechanism 6 is used by... Figure 4 As shown (the dashed box in the figure represents the anode carbon block), Figure 4 The top center shows the flipping mechanism 6 in a non-operating state. Figure 4 The change from left to right in the lower middle section refers to the change in state when the flipping mechanism 6 is working. The flipping mechanism 6 has a gap in the middle area of ​​the conveyor belt, allowing the first link 63 and the second link 64 below to pass through the conveyor belt. When the first link 63 and the second link 64 are stationary, the angle between them is 180°, that is, they are flush with or slightly lower than the surface of the conveyor belt. When the carbon bowl of the anode carbon block is cleaned and it needs to be flipped, the first connecting rod 63 on the left remains stationary, while the second connecting rod 64 on the right rotates 90° under the action of the motor, making the first connecting rod 63 and the second connecting rod 64 perpendicular to each other. When the bottom surface and the right vertical surface of the anode carbon block contact the first connecting rod 63 and the second connecting rod 64 respectively, the motor controls the main shaft 61 to rotate 90° while the second connecting rod 64 remains stationary, causing the anode carbon block to be flipped 90° to the right. At this time, the carbon bowl on the original upper surface of the anode carbon block flips to the right vertical surface, and the original bottom surface flips to the left vertical surface, exposing the original bottom surface of the anode carbon block for subsequent cleaning. After flipping, the first connecting rod 63 is controlled by the motor to rotate in the opposite direction to its original horizontal position, and the second connecting rod 64 is controlled by the motor to rotate in the opposite direction to its original horizontal position, waiting for the next flipping action.

[0037] In some embodiments, the aforementioned filter tube assembly 42 is further rearped by a settling chamber 7, which includes a capillary spray tube that automatically discharges water, and the controller is connected to the water pump of the capillary spray tube.

[0038] In this embodiment, the dust removal device filters and separates the impurities after they are drawn in through the filter tube assembly 42. The carbon powder that has passed through the filter tube assembly 42 is then drawn into the settling chamber 7. The capillary spray pipes installed in the settling chamber 7 are used to settle the suspended carbon powder in the settling chamber 7. After a period of settling, the mixture containing carbon powder and water can be further separated into solid and liquid components. The dried carbon powder can then be recycled. This not only improves the practicality of the cleaning system but also saves energy and effectively reduces production costs.

[0039] In some embodiments, the filter assembly 42 includes a cylindrical outer casing and a plurality of filter screens with different porosities disposed inside the outer casing, the cylindrical outer casing being installed at an angle relative to the ground.

[0040] In this embodiment, the aforementioned filter tube assembly 42 adopts a cylindrical outer casing. Filter screens with different porosities are installed inside the outer casing to separate impurities of different sizes, thereby improving the filtration quality. The inclined installation of the cylindrical outer casing allows the separated impurities to slide down into different discharge ports on the outer casing under their own gravity. This embodiment does not impose specific limitations on the aforementioned filter screens or their arrangement within the outer casing; the filter screen can be selected based on the specifications of the impurities to be filtered.

[0041] In other embodiments, the system includes two sets of horizontally and synchronously controlled flipping mechanisms 6.

[0042] In this embodiment, the flipping mechanism 6 located below the conveyor belt in the conveyor mechanism 2 is configured in two sets to be compatible with anode carbon blocks of different specifications. The torque of a single set of flipping mechanism 6 is limited, so the weight of the anode carbon block it can bear is limited. Therefore, setting two sets can improve the load-bearing capacity of the flipping mechanism 6, thereby being compatible with anode carbon blocks of various weight specifications, and further improving the practicality of the cleaning system.

[0043] In addition, in some embodiments, a slide rail is provided above the roller transport mechanism 1 behind the conveyor mechanism 2, and a slider with a scraper is slidably connected to the slide rail, and a cylinder controls the slider to move back and forth along the slide rail.

[0044] In this embodiment, after the anode carbon block is cleaned by the dust removal device, when the anode carbon block enters the subsequent roller transport mechanism 1, a scraper that can reciprocate along the extension direction of the roller is provided on the roller transport mechanism 1. The scraper is used to remove the carbon powder deposited on the bottom surface of the anode carbon block after it has been turned over, so as to perform a more comprehensive cleaning of the surface of the anode carbon block and further improve the practicality of the cleaning system.

[0045] The blade of the aforementioned scraper is a flexible plate, and the blade is used for interference fit on the surface of the anode carbon block.

[0046] In this design, the scraper used to clean the bottom surface of the flipped anode carbon block is designed as a flexible plate to protect the bottom surface of the anode carbon block from excessive wear by the scraper. The flexible plate is press-fitted with the bottom surface of the anode carbon block, thereby removing the carbon powder deposited on the bottom surface of the anode carbon block while protecting the bottom surface from excessive wear by the scraper.

[0047] In addition, the aforementioned scraper may also include two sets arranged perpendicular to each other.

[0048] In this design, the aforementioned scraper includes two sets arranged vertically and spaced apart. Different interference fits can be set to achieve the step-by-step scraping of carbon powder deposited on the bottom surface, further improving the practicality of the cleaning system.

Where the description in a particular embodiment is not exhaustive, please refer to the description in other embodiments.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
