Description

Technical Field

[0001] The present invention relates to the technical field of graphite electrode production equipment, and more specifically to a device for cleaning residue from graphite impregnation tanks. In particular, it relates to a highly efficient cleaning device that integrates an adaptive angle adjustment mechanism with a dry ice blasting system. This device is suitable for removing residual impurities such as asphalt coagulants, carbon residue, and quinoline insolubles from the inner walls and bottom of the impregnation tank, significantly improving cleaning efficiency and eliminating the safety risks of manual labor. Background Art

[0002] In the production process of graphite electrodes, the impregnation process is one of the key links. The graphite impregnation tank is the core equipment of this process. After use, a large amount of asphalt and residue will remain inside it. For a long time, the cleaning of these residues has mainly relied on manual work. The manual cleaning method has many disadvantages. First, due to the relatively small space inside the impregnation tank and the complex environment, manual operation is difficult and the labor intensity is extremely high. Cleaners need to work inside the tank for a long time, which makes them very tired. In response to the above problems, the prior art (publication number: CN221414357U) proposes a device for removing residue from a horizontal impregnation tank for graphite electrodes. The solution is as follows: a device for removing residue from a horizontal impregnation tank for graphite electrodes is horizontally placed on a track of the impregnation tank, comprising a mobile trolley, a vibrating crushing chisel, and a vacuum cleaner; the mobile trolley is arranged on the track, and the mobile trolley comprises a trolley frame and guide wheels, and a plurality of guide wheels are provided at the bottom of the front and rear sides of the trolley frame; the inner cavity of the mobile trolley is divided into a cleaning tank and a recovery tank; a plurality of vibrating crushing chisels are hingedly connected to the left wall of the mobile trolley; a vacuum port is provided at the bottom of the recovery tank, and one end of the vacuum cleaner passes through the vacuum port and enters the interior of the recovery tank. However, in actual operation, the cleaning direction of the prior art is single, so when cleaning different directions of the tank body, it is necessary to manually lay tracks in different directions, which wastes a certain amount of manpower and reduces the cleaning efficiency. At the same time, the device uses a vibrating crushing chisel assembly to clean the residue inside the tank body, which is very likely to cause damage to the inside of the tank body, thereby reducing the service life of the tank body. Therefore, there is an urgent need for a device for cleaning the residue of the graphite impregnation tank to solve the technical problems raised above. Summary of the Invention

[0025] Reference Figures 1 to 3 As shown, the present invention provides a device for cleaning residues in a graphite impregnation tank, comprising a graphite impregnation tank 1, wherein an omnidirectional scraping assembly 3 is provided on the top of the graphite impregnation tank 1 for scraping and cleaning residues adhered to the inner wall of the graphite impregnation tank 1; An adjustable lifting assembly 2 is provided at the bottom of the graphite impregnation tank 1, which is used to assist the omnidirectional scraping assembly 3 in scraping and cleaning the residue attached to the inner wall of the graphite impregnation tank 1. The adjustable lifting assembly 2 includes an electrically controlled hydraulic column 201, wherein the lifting end of the electrically controlled hydraulic column 201 is movably mounted with an auxiliary lifting column 202, and a servo motor 205 is mounted on the top of the auxiliary lifting column 202. The output end of the servo motor 205 is mounted with an adjusting gear 204, which is used to cooperate with the omnidirectional scraping assembly 3 to perform corresponding angle adjustment, so as to facilitate the omnidirectional scraping and cleaning operation of the inner wall of the graphite impregnation tank 1; The adjustable lifting component 2 and the omnidirectional scraping component 3 input a stable working current to perform an all-round cleaning operation on the inner side of the graphite impregnation tank 1. During the cleaning process of the all-round scraping component 3, dry ice is sprayed on the inner side of the graphite impregnation tank 1 to further improve the cleaning efficiency of the residue attached to the inner wall of the graphite impregnation tank 1.

[0026] In the embodiment of the present application, the specific working process of the embodiment of this part of the application is as follows: when the residue cleaning operation is required inside the graphite impregnation tank 1, the residual liquid inside the graphite impregnation tank 1 is cleaned and recovered manually. After completing the above steps, the electric-controlled hydraulic column 201 inputs a stable working current to control its lifting end to move to the top position of the graphite impregnation tank 1, and the auxiliary lifting column 202 is manually installed on the lifting end.

The inner side of the collecting tray 206 is provided with a storage cabin for recovering the residues collected on the inner side of the graphite impregnation tank 1.

[0028] In the embodiment of the present application, the specific working process of this part of the application embodiment is: during the process of scraping and cleaning the residue on the inner side of the graphite impregnation tank 1 by the adjustable lifting component 2 and the omnidirectional scraping component 3, the cleaned residue is moved to the storage cabin of the collection tray 206 under the driving force of gravity. After the adjustable lifting component 2 and the omnidirectional scraping component 3 have completed cleaning the residue adhered to the inner side of the graphite impregnation tank 1, the electric-controlled hydraulic column 201 inputs a stable working current to drive the collection tray 206 to move to the top of the graphite impregnation tank 1, so that the staff can disassemble the collection tray 206 and recycle the residue inside the storage cabin.

[0029] Reference Figures 1 to 3 as well as Figures 5 to 8 As shown, the present invention provides a device for cleaning residues in a graphite impregnation tank. The omnidirectional scraping assembly 3 includes a limiting assembly 301, wherein the limiting assembly 301 is installed on the side of the top of the graphite impregnation tank 1, and a position adjustment device 302 is installed on the top of the limiting assembly 301. A support plate 303 is fixedly installed on one end of the position adjustment device 302 away from the limiting assembly 301, and a limiting support pillar 304 is fixedly installed on the side of the support plate 303 away from the position adjustment device 302. The bottom of the limiting pillar 304 is movably connected to an electric-controlled dry-cleaning device 305, wherein a limiting plate 306 is fixedly installed at the bottom of the electric-controlled dry-cleaning device 305. Electric-controlled lifting columns 307 are installed on both sides of the bottom surface of the limiting plate 306. The weighing part of the electric-controlled lifting columns 307 is installed with a lifting ring plate 309. The electrically controlled dry cleaning device 305 receives a stable operating current, driving the dry ice inside to be transported to the interior of the limit plate 306. A telescopic delivery tube 308 is installed on the bottom surface of the electrically controlled dry cleaning device 305 near the electrically controlled lifting column 307. One end of the telescopic delivery tube 308 extends into the interior of the limit plate 306, and the other end of the telescopic delivery tube 308 extends into the interior of the lifting ring plate 309. The dry ice inside the limit plate 306 is transported to the interior of the lifting ring plate 309 through the telescopic delivery tube 308. The lifting annular plate 309 has multiple groups of delivery holes 3091 formed in sequence and at equal intervals inside. One end of each group of delivery holes 3091 extends to the inner wall of the lifting annular plate 309. The lifting annular plate 309 is provided with a delivery support plate 310 on the outer side surface near each group of delivery holes 3091. Each group of delivery support plates 310 has a delivery groove 3101 formed inside, and the delivery groove 3101 is in a state of mutual communication with the delivery holes 3091. A scraping plate 311 is installed on the side of the delivery support plate 310 away from the lifting annular plate 309. The inner wall of the scraping plate 311 is provided with an inclined through-hole, wherein one end of the output hole extends to the outer side of the scraping plate 311, and the other end of the output hole extends to the interior of the delivery trough 3101. A torsion spring plate 312 is movably installed on the inner side of the output hole, and a torsion spring is provided at the connection between the torsion spring plate 312 and the output hole for controlling the flow direction of dry ice in the output hole. A slider 314 is installed on the inner ring surface of the bottom of the lifting ring plate 309, and multiple groups of slide grooves 203 are sequentially opened on the outer side surface of the auxiliary lifting column 202. The outer side surface of the slider 314 is adapted to the inner side surface of each group of slide grooves 203. An internal gear plate 313 is installed on the inner ring surface of the top of the lifting ring plate 309. The inner side surface of the internal gear plate 313 is provided with a gear groove, which is adapted to the outer side surface of the adjusting gear 204.

[0030] In the embodiment of the present application, a rubber pad is provided on the outer side surface of the slider 314 near the auxiliary lifting column 202, which is conducive to the rubber pad being in a deformed state when moving to the outer side surface of the adjusting gear 204, and will not cause wear to the working state of the adjusting gear 204; when the lifting annular plate 309 moves on the surface of the auxiliary lifting column 202, the inner side surface of the inner gear plate 313 cannot contact the outer surface of the auxiliary lifting column 202.

[0031] The specific working process of the embodiment of this part of the application is as follows: after the adjustable lifting assembly 2 is installed inside the graphite impregnation tank 1, the position adjustment device 302 inputs a stable working current to control the support plate 303 to rotate 180 degrees, and controls the lifting ring plate 309 to move to the top position of the auxiliary lifting column 202. The electric lifting column 307 inputs a stable working current to control the lifting ring plate 309 to move to the outer side of the auxiliary lifting column 202 until the slider 314 moves to the inner wall of the corresponding slide groove 203. The electric lifting column 307 continuously inputs a stable working current to control the lifting ring plate 309, the conveying support plate 310 and the scraping plate 311 to slowly move from the top to the bottom of the graphite impregnation tank 1. During the movement of the scraping plate 311, the residue attached to the inner surface of the graphite impregnation tank 1 is automatically scraped. During this scraping process, the electric lifting column 307 inputs a stable working current to drive the scraping plate 311 to move the inner surface of the graphite impregnation tank 1 up and down. This scraping process lasts for 10-15 minutes. After the scraping process is completed, the electric-controlled lifting column 307 inputs a stable working current to drive the lifting ring plate 309 to move to the top of the graphite impregnation tank 1, and the outer side surface of the adjusting gear 204 moves into the gear groove opened on the inner side surface. At this time, the slider 314 disengages from the inner side surface of the slide groove 203, and the servo motor 205 inputs a stable working power to control the adjusting gear 204 to rotate a certain angle. After the rotation is completed, the electric-controlled lifting column 307 controls the lifting ring plate 309 to move downward, and the slider 314 moves to the inner side surface of the corresponding slide groove 203, and repeats step 1 at the same time, so as to perform a full-scale scraping and cleaning operation on the inner side surface of the graphite impregnation tank 1. In addition, this process does not require manpower or intervention, further improving the cleaning efficiency of the residue inside the graphite impregnation tank 1 and further reducing the cleaning cost inside the graphite impregnation tank 1. When the scraping plate 311 cleans the residue on the inner side of the graphite impregnation tank 1, the electrically controlled dry cleaning device 305 inputs a stable working current, and the electrically controlled dry cleaning device 305 controls the dry ice inside to be input into the interior of the limit plate 306, and then input into the interior of the conveying trough 3101 through the telescopic conveying tube 308, the interior of the lifting annular plate 309, and the conveying hole 3091. When the storage volume inside the conveying trough 3101 reaches the rated value, the torsion spring plate 312 is controlled to be in an open state, and the dry ice inside the conveying trough 3101 is transmitted to the inner side of the graphite impregnation tank 1 through the output hole opened at one end of the conveying support plate 310. During this process, the dry ice particles will collide with the residue to make it brittle and peel off. At the same time, the low temperature causes the residue to shrink and peel off from the substrate. The dry ice instantly sublimates and vaporizes without generating secondary waste, thereby further improving the cleaning efficiency of the residue inside the graphite impregnation tank 1. During the dry ice cleaning process, when the amount of dry ice inside the conveying trough 3101 reaches the rated value, the dry ice will not explode due to the increase in internal pressure. The amount of dry ice within this rated range is in a relatively safe state.

[0032] The specific workflow of this application is as follows: Movement process: When the residue cleaning operation is required inside the graphite impregnation tank 1, the residual liquid inside the graphite impregnation tank 1 is cleaned and recovered manually. After completing the above steps, the electric-controlled hydraulic column 201 inputs a stable working current to control its lifting end to move to the top of the graphite impregnation tank 1, and the auxiliary lifting column 202 is manually installed on the lifting end. After the auxiliary lifting column 202 is installed, the electric-controlled hydraulic column 201 inputs a stable working current to control its lifting end and the auxiliary lifting column 202 to move to the bottom of the graphite impregnation tank 1, and the omnidirectional scraping component 3 moves to the surface of the auxiliary lifting column 202; Cleaning process: After the adjustable lifting assembly 2 is installed inside the graphite impregnation tank 1, the position adjustment device 302 inputs a stable working current to control the support plate 303 to rotate 180 degrees, and controls the lifting ring plate 309 to move to the top position of the auxiliary lifting column 202. The electric lifting column 307 inputs a stable working current to control the lifting ring plate 309 to move to the outer side of the auxiliary lifting column 202 until the slider 314 moves to the inner wall of the corresponding slide groove 203. The electric lifting column 307 continuously inputs a stable working current to control the lifting ring plate 309, the conveying support plate 310 and the scraping plate 311 to move slowly from the top to the bottom of the graphite impregnation tank 1. During the movement of the scraping plate 311, the residue attached to the inner surface of the graphite impregnation tank 1 is automatically scraped. During the scraping process, the electric lifting column 307 inputs a stable working current to drive the scraping plate 311 to move the inner surface of the graphite impregnation tank 1 up and down. The scraping process lasts for 10-15 minutes. Step 2. After the scraping process is completed, the electric-controlled lifting column 307 inputs a stable working current to drive the lifting ring plate 309 to move to the top of the graphite impregnation tank 1, and the outer side surface of the adjusting gear 204 moves into the gear groove opened on the inner side surface. At this time, the slider 314 disengages from the inner side surface of the slide groove 203, and the servo motor 205 inputs a stable working power to control the adjusting gear 204 to rotate a certain angle. After the rotation is completed, the electric-controlled lifting column 307 controls the lifting ring plate 309 to move downward, and the slider 314 moves to the inner side surface of the corresponding slide groove 203, and repeats step 1 at the same time, so as to perform a full-scale scraping and cleaning operation on the inner side surface of the graphite impregnation tank 1. This process does not require manpower or intervention, further improving the cleaning efficiency of the residue inside the graphite impregnation tank 1 and further reducing the cleaning cost inside the graphite impregnation tank 1. Dry ice cleaning: When the scraping plate 311 cleans the residue on the inner surface of the graphite impregnation tank 1, the electrically controlled dry cleaning device 305 inputs a stable working current. The electrically controlled dry cleaning device 305 controls the dry ice inside to be input into the interior of the limit plate 306, and then input into the interior of the conveying trough 3101 through the telescopic conveying tube 308, the interior of the lifting annular plate 309 and the conveying hole 3091. When the storage volume inside the conveying trough 3101 reaches the rated value, the torsion spring plate 312 will be controlled to be in an open state, and the dry ice inside the conveying trough 3101 will be transmitted to the inner surface of the graphite impregnation tank 1 through the output hole opened at one end of the conveying support plate 310. During this process, the dry ice particles will collide with the residue to make it brittle and peel off. At the same time, the low temperature causes the residue to shrink and peel off from the substrate. The dry ice will instantly sublimate and vaporize without generating secondary waste, thereby further improving the cleaning efficiency of the residue inside the graphite impregnation tank 1.
