Description

Technical Field

[0001] This invention relates to the field of graphite electrode production equipment technology, and more specifically to a device for cleaning residues from graphite impregnation tanks; particularly, it relates to a high-efficiency cleaning device integrating an angle adaptive adjustment mechanism and a dry ice spray system. This device is suitable for removing residual impurities such as asphalt curds, carbon slag, and quinoline insolubles from the inner wall and bottom of the impregnation tank, significantly improving cleaning efficiency and eliminating the safety risks of manual operation. Background Technology

[0002] In the production of graphite electrodes, the impregnation process is one of the key steps. The graphite impregnation tank, as the core equipment in this process, accumulates a large amount of asphalt and residue after use. For a long time, the cleaning of these residues has relied mainly on manual labor. This manual cleaning method has many drawbacks. First, due to the relatively small and complex internal space of the impregnation tank, manual operation is difficult and extremely labor-intensive. Cleaning personnel need to work inside the tank for extended periods, leading to rapid physical fatigue.

[0003] To address the aforementioned issues, existing technology (publication number: CN221414357U) proposes a device for removing residue from a horizontal graphite electrode impregnation tank. The solution is as follows: A device for removing residue from a horizontal graphite electrode impregnation tank is horizontally placed on a track of the impregnation tank, including a moving trolley, a vibrating crusher, and a vacuum cleaner. The moving trolley is positioned on the track and includes a trolley frame and guide wheels. Several guide wheels are located at the bottom of the front and rear sides of the trolley frame. The inner cavity of the moving trolley is divided into a cleaning tank and a recovery tank. Several vibrating crushers are hinged to the left side wall of the moving trolley. A suction port is located at the bottom of the recovery tank, and one end of the vacuum cleaner passes through the suction port to enter the recovery tank. However, in actual operation, this existing technology has a single cleaning direction. Therefore, when cleaning different parts of the tank, tracks in different directions need to be laid manually, which wastes manpower and reduces cleaning efficiency. Furthermore, this device uses a vibrating crusher assembly to clean residue inside the tank, which can easily cause damage to the inside of the tank, thus reducing its service life.

[0004] Therefore, there is an urgent need for a device to clean the residue from graphite impregnation tanks in order to solve the aforementioned technical problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an apparatus for cleaning residues from graphite impregnation tanks, so as to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: a device for cleaning residues in a graphite impregnation tank, comprising a graphite impregnation tank, wherein the top of the graphite impregnation tank is provided with an all-round scraping component for scraping and cleaning residues adhering to the inner wall of the graphite impregnation tank.

[0007] The bottom of the graphite impregnation tank is equipped with an adjustable lifting component to assist the all-around scraping component in scraping and cleaning the residue adhering to the inner wall of the graphite impregnation tank. The adjustable lifting component includes an electro-hydraulic column, wherein an auxiliary lifting column is movably installed at the lifting end of the electro-hydraulic column, and a servo motor is installed at the top of the auxiliary lifting column. An adjusting gear is installed at the output end of the servo motor to cooperate with the all-around scraping component to make corresponding angle adjustments, so as to facilitate all-around scraping and cleaning of the inner wall of the graphite impregnation tank.

[0008] The adjustable lifting assembly and the all-around scraping assembly input a stable working current to perform all-around cleaning of the inner surface of the graphite impregnation tank. During the cleaning process of the all-around scraping assembly, dry ice is sprayed onto the inner surface of the graphite impregnation tank to further improve the cleaning efficiency of the residue adhering to the inner wall of the graphite impregnation tank.

[0009] Furthermore, a collection tray is installed on the outer side of the bottom of the auxiliary lifting column. A rubber layer is laid on the upper surface of the collection tray. When the collection tray moves into the graphite impregnation tank, the rubber layer can contact the inner side of the graphite impregnation tank. A storage compartment is opened on the inner side of the collection tray for recycling the residue collected on the inner side of the graphite impregnation tank.

[0010] The all-around scratch component includes a limiting component.

[0011] Furthermore, the limiting component is installed on the side of the top of the graphite impregnation tank, a position adjustment device is installed on the top of the limiting component, a support plate is fixedly installed on the end of the position adjustment device away from the limiting component, and a limiting support column is fixedly installed on the side of the support plate away from the position adjustment device.

[0012] Furthermore, an electrically controlled dry cleaning device is movably sleeved at the bottom of the limiting support column, wherein a limiting plate is fixedly installed at the bottom of the electrically controlled dry cleaning device, and electrically controlled lifting columns are installed on both sides of the bottom surface of the limiting plate, and a lifting ring plate is installed on the weighing part of the electrically controlled lifting column.

[0013] Furthermore, the electronically controlled dry cleaning device inputs a stable working current to drive the dry ice inside it to be transported to the inside of the limiting plate. The electronically controlled dry cleaning device has a telescopic conveying pipe installed on its bottom surface near the electronically controlled lifting column. One end of the telescopic conveying pipe extends into the inside of the limiting plate, and the other end extends into the inside of the lifting ring plate. The dry ice inside the limiting plate is transported to the inside of the lifting ring plate through the telescopic conveying pipe.

[0014] The lifting annular plate has multiple sets of conveying holes arranged at equal intervals inside.

[0015] Furthermore, one end of each of the multiple sets of conveying holes extends to the inner wall of the lifting annular plate, and a conveying support plate is installed on the outer side of the lifting annular plate near each set of conveying holes. Each set of conveying support plates has a conveying groove inside, and the conveying groove and the conveying hole are in a mutually flowing state.

[0016] Furthermore, a scraper plate is installed on the side of the conveying support plate away from the lifting ring plate. The inner wall of the scraper plate has an inclined through-hole, one end of which extends to the outer side of the scraper plate and the other end of which extends into the interior of the conveying groove. A torsion spring plate 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 and the output hole to control the flow direction of dry ice inside the output hole.

[0017] A slider is installed on the inner ring surface at the bottom of the lifting ring plate.

[0018] Furthermore, multiple sets of sliding grooves are sequentially opened on the outer side of the auxiliary lifting column, and the outer side of the slider is adapted to the inner side of each set of sliding grooves. An internal gear plate is installed on the inner ring surface of the top of the lifting annular plate, and a gear groove is opened on the inner side of the internal gear plate, which is adapted to the outer side of the adjusting gear.

[0019] Furthermore, the slider 314 has a rubber pad on its outer side near the auxiliary lifting column 202, which is beneficial to the rubber pad being in a deformed state when it moves to the outer side of the adjusting gear 204, so as not to cause wear to the working state of the adjusting gear 204; during the movement of the lifting ring plate 309 on the surface of the auxiliary lifting column 202, the inner side of the inner gear plate 313 cannot contact the outer surface of the auxiliary lifting column 202.

[0020] The technical effects and advantages of this invention are as follows:

[0021] This invention uses an electro-hydraulic column to input a stable working current, controlling its lifting end to move to the top of the graphite impregnation tank. An auxiliary lifting column is then manually installed on this lifting end. After installation, the electro-hydraulic column inputs a stable working current, controlling its lifting end and the auxiliary lifting column to move to the bottom of the graphite impregnation tank. The omnidirectional scraping component moves to the surface of the auxiliary lifting column. At this point, the adjustable lifting component and the omnidirectional scraping component input a stable working current to perform an omnidirectional cleaning operation on the inner surface of the graphite impregnation tank. During the cleaning process, dry ice is sprayed onto the inner surface of the graphite impregnation tank to further improve the cleaning efficiency of residues adhering to the inner wall of the tank.

[0022] This invention uses an electrically controlled lifting column to input a stable working current, which drives a lifting annular plate to move to the top of the graphite impregnation tank. The outer side of the adjusting gear moves into the gear groove on the inner side. At this time, the slider disengages from the inner side of the groove. The servo motor inputs stable working power to control the adjusting gear to rotate a certain angle. After the rotation is completed, the electrically controlled lifting column controls the lifting annular plate to move downward, and the slider moves to the inner side of the corresponding groove. The all-round scraping component inputs current to facilitate all-round scraping and cleaning of the inner side of the graphite impregnation tank. This process requires no human intervention, further improving the cleaning efficiency of the residue inside the graphite impregnation tank and further reducing the cleaning cost inside the graphite impregnation tank.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The apparatus for cleaning residues from graphite impregnation tanks involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 3 As shown, the present invention provides an apparatus for cleaning residues in a graphite impregnation tank, including a graphite impregnation tank 1, wherein the top of the graphite impregnation tank 1 is provided with an all-around scraping component 3 for scraping and cleaning residues adhering to the inner wall of the graphite impregnation tank 1.

[0034] The bottom of the graphite impregnation tank 1 is provided with an adjustable lifting component 2, which is used to assist the all-round scraping component 3 in scraping and cleaning the residue adhering to the inner wall of the graphite impregnation tank 1. The adjustable lifting component 2 includes an electro-hydraulic column 201, wherein an auxiliary lifting column 202 is movably installed at the lifting end of the electro-hydraulic column 201. A servo motor 205 is installed at the top of the auxiliary lifting column 202, and an adjusting gear 204 is installed at the output end of the servo motor 205, which is used to cooperate with the all-round scraping component 3 to make corresponding angle adjustments, so as to facilitate the all-round scraping and cleaning operation of the inner wall of the graphite impregnation tank 1.

[0035] The adjustable lifting component 2 and the all-round scraping component 3 input a stable working current to perform all-round cleaning of the inner side of the graphite impregnation tank 1. During the cleaning process, the all-round scraping component 3 sprays dry ice onto the inner side of the graphite impregnation tank 1 to further improve the cleaning efficiency of the residue adhering to the inner wall of the graphite impregnation tank 1.

[0036] In this embodiment of the application, the specific workflow of this part of the application embodiment is as follows: When the graphite impregnation tank 1 needs to be cleaned of residue, the residual liquid inside the graphite impregnation tank 1 is cleaned and recovered manually. After the above steps are completed, the electro-hydraulic column 201 is input with a stable working current to control its lifting end to move to the top of the graphite impregnation tank 1. The auxiliary lifting column 202 is installed on the lifting end manually. After the auxiliary lifting column 202 is installed, the electro-hydraulic column 201 is input with 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. The all-round scraping component 3 moves to the surface of the auxiliary lifting column 202. At this time, the adjustable lifting component 2 and the all-round scraping component 3 are input with a stable working current to perform all-round cleaning of the inner side of the graphite impregnation tank 1. During the cleaning process of the all-round scraping component 3, dry ice is sprayed onto the inner side of the graphite impregnation tank 1 to further improve the cleaning efficiency of the residue adhering to the inner wall of the graphite impregnation tank 1.

[0037] Reference Figures 1 to 4 As shown, the present invention provides a device for cleaning residue from a graphite impregnation tank. A collection tray 206 is installed on the outer side of the bottom of the auxiliary lifting column 202. A rubber layer is laid on the upper surface of the collection tray 206. When the collection tray 206 moves into the graphite impregnation tank 1, the rubber layer can contact the inner side of the graphite impregnation tank 1. A storage compartment is provided on the inner side of the collection tray 206 for recycling the residue collected on the inner side of the graphite impregnation tank 1.

[0038] In this embodiment of the application, the specific workflow of this part of the application embodiment is as follows: During the process of the adjustable lifting component 2 and the all-round scraping component 3 scraping and cleaning the residue on the inner side of the graphite impregnation tank 1, the cleaned residue moves to the storage compartment of the collection tray 206 under the drive of gravity. After the adjustable lifting component 2 and the all-round scraping component 3 have finished cleaning the residue adhering to the inner side of the graphite impregnation tank 1, the electro-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 compartment.

[0039] Reference Figures 1 to 3 as well as Figures 5 to 8 As shown, the present invention provides an apparatus for cleaning residue from a graphite impregnation tank. The all-around 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, a position adjustment device 302 is installed on the top of the limiting assembly 301, a support plate 303 is fixedly installed at one end of the position adjustment device 302 away from the limiting assembly 301, and a limiting support column 304 is fixedly installed on the side of the support plate 303 away from the position adjustment device 302.

[0040] The bottom of the limiting support column 304 is movably sleeved with an electrically controlled dry cleaning device 305, wherein a limiting plate 306 is fixedly installed at the bottom of the electrically controlled dry cleaning device 305, and electrically controlled lifting columns 307 are installed on both sides of the bottom surface of the limiting plate 306, and a lifting ring plate 309 is installed on the weighing part of the electrically controlled lifting column 307.

[0041] The electrically controlled dry cleaning device 305 is input with a stable working current to drive the dry ice inside it to be transported to the inside of the limiting plate 306. The electrically controlled dry cleaning device 305 has a telescopic conveying pipe 308 installed on its bottom surface near the electrically controlled lifting column 307. One end of the telescopic conveying pipe 308 extends into the inside of the limiting plate 306, and the other end extends into the inside of the lifting ring plate 309. The dry ice inside the limiting plate 306 is transported to the inside of the lifting ring plate 309 through the telescopic conveying pipe 308.

[0042] The lifting annular plate 309 has multiple sets of conveying holes 3091 arranged at equal intervals inside. One end of each set of conveying holes 3091 extends to the inner wall of the lifting annular plate 309. Conveying support plates 310 are installed on the outer side of the lifting annular plate 309 near each set of conveying holes 3091. Each set of conveying support plates 310 has a conveying groove 3101 inside, and the conveying groove 3101 and the conveying hole 3091 are in a mutual flow state.

[0043] A scraper plate 311 is installed on the side of the conveying support plate 310 away from the lifting ring plate 309. The inner wall of the scraper plate 311 has an inclined through-hole. One end of the output hole extends to the outer side of the scraper plate 311, and the other end extends to the inside of the conveying groove 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 to control the flow direction of dry ice inside the output hole.

[0044] A slider 314 is installed on the inner ring surface at the bottom of the lifting annular plate 309. Multiple sets of sliding grooves 203 are sequentially opened on the outer side of the auxiliary lifting column 202. The outer side of the slider 314 is adapted to the inner side of each set of sliding grooves 203. An internal gear plate 313 is installed on the inner ring surface at the top of the lifting annular plate 309. A gear groove is opened on the inner side of the internal gear plate 313, which is adapted to the outer side of the adjusting gear 204.

[0045] In this embodiment, the slider 314 has a rubber pad on its outer side near the auxiliary lifting column 202. This allows the rubber pad to be in a deformed state when it moves to the outer side of the adjusting gear 204, thus preventing wear on the adjusting gear 204. During the movement of the lifting ring plate 309 on the surface of the auxiliary lifting column 202, the inner side of the inner gear plate 313 cannot contact the outer surface of the auxiliary lifting column 202.

[0046] The specific workflow of this application embodiment 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 move slowly from the top to the bottom of the graphite impregnation tank 1. During the movement of the scraping plate 311, the residue adhering to the inner side 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 up and down on the inner side of the graphite impregnation tank 1. The scraping process lasts for 10-15 minutes.

[0047] After the above scraping process is completed, the electric 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. The outer side of the adjusting gear 204 moves to the gear groove opened on the inner side. At this time, the slider 314 disengages from the inner side of the slide groove 203. 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 lifting column 307 controls the lifting ring plate 309 to move downward. The slider 314 moves to the inner side of the corresponding slide groove 203. At the same time, step one is repeated to facilitate the all-round scraping and cleaning operation of the inner side of the graphite impregnation tank 1. This process does not require human intervention and further improves the cleaning efficiency of the residue inside the graphite impregnation tank 1 and further reduces the cleaning cost inside the graphite impregnation tank 1.

[0048] When the scraper 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. The electrically controlled dry cleaning device 305 controls the dry ice inside to be input into the limit plate 306. The dry ice is then input into the conveying trough 3101 through the telescopic conveying pipe 308, the lifting ring plate 309, and the conveying hole 3091. When the storage capacity inside the conveying trough 3101 reaches the rated value, the torsion spring plate 312 is controlled to be in the open state. 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 impact the residue, causing it to become brittle and peel off. At the same time, the low temperature causes the residue to shrink and peel off from the matrix. The dry ice sublimates and vaporizes instantly without producing secondary waste, further improving the cleaning efficiency of the residue inside the graphite impregnation tank 1.

[0049] During the dry ice cleaning process, when the amount of dry ice inside the conveying tank 3101 reaches the rated value, the dry ice will not explode due to the increase in internal pressure, and the amount of dry ice within this rated range is in a relatively safe state.

[0050] The specific workflow for this application is as follows:

[0051] Moving process: When the graphite impregnation tank 1 needs to be cleaned of residue, the residual liquid inside the graphite impregnation tank 1 is cleaned and recovered manually. After the above steps are completed, the electro-hydraulic column 201 is input with a stable working current to control its lifting end to move to the top of the graphite impregnation tank 1. The auxiliary lifting column 202 is installed on the lifting end manually. After the auxiliary lifting column 202 is installed, the electro-hydraulic column 201 is input with 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. The all-round scraping component 3 moves to the surface of the auxiliary lifting column 202.

[0052] Cleaning process:

[0053] Step 1: 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 continues to input 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, it automatically scrapes the residue adhering to the inner side of the graphite impregnation tank 1. During this scraping process, the electric lifting column 307 inputs a stable working current to drive the scraping plate 311 to move up and down on the inner side of the graphite impregnation tank 1. This scraping process lasts for 10-15 minutes.

[0054] Step 2: After the above scraping process is completed, the electric 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. The outer side of the adjusting gear 204 moves to the gear groove opened on the inner side. At this time, the slider 314 disengages from the inner side of the slide groove 203. 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 lifting column 307 controls the lifting ring plate 309 to move downward, and the slider 314 moves to the inner side of the corresponding slide groove 203. At the same time, Step 1 is repeated to facilitate the all-round scraping and cleaning operation of the inner side of the graphite impregnation tank 1. This process does not require human 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.

[0055] Dry ice cleaning: When the scraper 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. The electrically controlled dry cleaning device 305 controls the dry ice inside to be input into the limit plate 306. It is then input into the conveying trough 3101 through the telescopic conveying pipe 308, the lifting ring plate 309, and the conveying hole 3091. When the storage capacity inside the conveying trough 3101 reaches the rated value, the torsion spring plate 312 is controlled to be in the open state. 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 impact the residue, causing it to become brittle and peel off. At the same time, the low temperature causes the residue to shrink and peel off from the matrix. The dry ice sublimates and vaporizes instantly without producing secondary waste, further improving the cleaning efficiency of the residue inside the graphite impregnation tank 1.
