Description

Technical Field

[0001] This invention relates to a cathode carbon block cleaning system, specifically an automatic cathode carbon block cleaning system. Background Technology

[0002] To facilitate the assembly of cathode carbon blocks and prevent the adhering filler material from falling into the electrolytic cell and affecting the quality of the primary aluminum, the calcined layer adhering to the surface of the cathode carbon blocks must be cleaned before they are transferred to the next process. This cleaned-off calcined layer must be recycled. The recycling price differs between the cathode carbon blocks and the calcined layer, with the cathode carbon blocks fetching several times the price of the calcined layer. Since each cathode carbon block can weigh several tons, manual cleaning would result in high labor intensity, low production efficiency, and severe environmental pollution. Currently, there are no automated cleaning lines on the market that cover the entire process of feeding, cleaning, and unloading cathode carbon blocks. Summary of the Invention

[0003] In order to solve the problems in related technologies, the present invention provides an automatic cleaning system for cathode carbon blocks. This device solves the problem that there is no automatic cleaning line for the entire cleaning process of cathode carbon blocks in the prior art.

[0004] To solve the above problems, the following technical solutions are provided:

[0005] An automatic cathode carbon block cleaning system is characterized by including a first conveying mechanism and a first fixing mechanism and a second fixing mechanism respectively disposed at one end and the middle of the first conveying mechanism along its length. Both the first fixing mechanism and the second fixing mechanism are used to fix the cathode carbon block and synchronously carry the cathode carbon block to move along the length of the first conveying mechanism in the same direction.

[0006] A feeding mechanism is provided on one side of the width direction of the first conveying mechanism, and the feeding mechanism is used to convey the cathode carbon block to the first fixing mechanism;

[0007] In the second fixing mechanism, a first cleaning mechanism is provided on both sides of the first conveying mechanism in the width direction near the first fixing mechanism. The two first cleaning mechanisms are used to clean the opposite two vertical surfaces of the cathode carbon block in the width direction.

[0008] A flipping mechanism is provided on one side of the width direction of the first conveying mechanism, and the flipping mechanism is located on the side of the first cleaning mechanism away from the feeding mechanism. The flipping mechanism is used to remove the cathode carbon block on the second fixing mechanism, flip the cathode carbon block 90° and place it on the second fixing mechanism.

[0009] The second fixing mechanism is provided with a second cleaning mechanism on both sides of the width direction of the first conveying mechanism on the side away from the first cleaning mechanism. The two second cleaning mechanisms are used to clean the other two opposite vertical surfaces in the width direction of the cathode carbon block.

[0010] A third cleaning mechanism is provided at the other end of the length direction of the first conveying mechanism, and the third cleaning mechanism is located on one side of the width direction of the first conveying mechanism. The third cleaning mechanism is used to clean the opposite two vertical surfaces of the cathode carbon block in the length direction.

[0011] A feeding mechanism is provided between the first conveying mechanism and the third cleaning mechanism. The feeding mechanism is used to convey the cathode carbon block on the second fixing mechanism to the third cleaning mechanism.

[0012] Through the above technical solution, the first cleaning mechanism can clean the calcined layer on two opposite side surfaces in the width direction of the cathode carbon block. After cleaning, the position of the cathode carbon block is adjusted by the flipping mechanism. After adjustment, the second cleaning mechanism cleans the other two side surfaces in the width direction of the cathode carbon block. Finally, the third cleaning mechanism cleans the calcined layer on both side surfaces in the length direction, thereby cleaning the calcined layer on every part of the cathode carbon block. Moreover, the entire cleaning process, from centering, feeding, fixing, cleaning and unloading of the cathode carbon block, does not require manual transmission, flipping and cleaning, thus speeding up the cleaning efficiency.

[0013] By using a first and a second fixing mechanism that move in the same direction and synchronously, when the first fixing mechanism moves with a carbon block for cleaning, the second fixing mechanism will also move with another carbon block for cleaning, thereby speeding up the cleaning efficiency of this cleaning system.

[0014] Furthermore, it also includes a centering mechanism, which is located at one end of the feeding port in the feeding mechanism. The centering mechanism is used to receive the cathode carbon block and adjust the position of the cathode carbon block.

[0015] Furthermore, the first conveying mechanism includes a first support frame and two first guide rails. The two first guide rails are arranged in parallel on the top of the first support frame. Both first guide rails are arranged along the length direction of the first support frame, and each first guide rail is a ball bearing guide rail.

[0016] Both the first fixing mechanism and the second fixing mechanism are slidably engaged with the first guide rail through multiple sliding mechanisms; each sliding mechanism includes a sliding guide seat and multiple first bearings, each sliding guide seat is fixedly installed at the bottom of the corresponding first fixing mechanism or second fixing mechanism, each sliding guide seat has a first limiting groove in the middle of its lower part, the width of the first limiting groove is the same as that of the first guide rail, multiple first bearings are respectively arranged on both sides of the width direction of the first limiting groove, each first bearing has a first connecting shaft fixedly installed on its inner ring, the other end of each first connecting shaft is fixedly connected to the corresponding sliding guide seat, and the outer curved surface of the outer ring of each first bearing abuts against the side surface of the first guide rail;

[0017] The first support frame includes a top support plate and a bottom support plate. The bottom support plate is provided with a plurality of first mounting parts for fixing. The top support plate is provided above the bottom support plate by a plurality of support beams. The first guide rail is provided on the top of the top support plate.

[0018] Each of the sliding guide seats is provided with a reverse hook plate on its side surface. The reverse hook plate is vertically arranged and its lower part extends to the bottom of the sliding guide seat. Each of the reverse hook plates is provided with a second bearing on its side surface near the first guide rail. The inner ring of each second bearing is fixedly connected to the corresponding reverse hook plate through a second connecting shaft. The outer curved surface of the outer ring of each second bearing abuts against the bottom of the support top plate.

[0019] Through the above technical solution, by setting up ball guides, the rolling friction of ball guides is much lower than that of linear guides, which can significantly reduce energy loss and wear. In dusty environments, the lubrication requirements of ball guides are lower, and they are less prone to jamming or wear due to dust accumulation, thereby extending service life and reducing maintenance needs. In addition, ball guides can withstand greater radial and axial loads, thus enabling them to stably support heavy objects during long-distance movement, reducing deformation or damage caused by uneven loads, thereby extending service life and reducing maintenance needs.

[0020] By setting up the first and second bearings, when the first and second fixing mechanisms move along the first guide rail, the bearings can effectively prevent dust, sand and other contaminants from entering the bearing interior, thereby extending the service life of each structure and reducing maintenance costs.

[0021] Further, the first cleaning mechanism comprises a support base and two second support frames, a plurality of second mounting members for fixing are arranged on the support base, the width direction of the support base is consistent with the length direction of the first conveying mechanism, the two second support frames are respectively arranged on two sides of the support base in the width direction, both of the two second support frames are arranged in a "loop" shape, a milling drum and a flail hammer drum are respectively arranged on the side vertical surfaces of the two support frames close to the first conveying mechanism, and the two support frames are provided with drive motors which are respectively in linkage connection with the milling drum and the flail hammer drum;

[0022] The flail hammer drum comprises a flail hammer roller and a plurality of flail hammer assemblies, the plurality of flail hammer assemblies are sequentially arranged in a spiral shape along the outer curved surface of the flail hammer roller, each flail hammer assembly comprises a fixing seat and a flail hammer cutter, each fixing seat is fixedly installed on the flail hammer roller, one end of each flail hammer cutter is flexibly connected with the corresponding fixing seat, and the end of each flail hammer cutter far away from the fixing seat is arranged in an arc shape.

[0023] Through the above technical solution, by the arrangement of the milling drum and the flail hammer drum, when cleaning the roasting layer on the surface of the cathode carbon block, the milling drum serves as the first cleaning step, the milling drum with point destruction characteristics can clean 80-90% of the roasting layer, which can improve the cleaning efficiency of the cathode carbon block. After the first cleaning, the flail hammer drum is used for the second cleaning. Since the flail hammer cutter and the flail hammer roller are flexibly connected, when the flail hammer cutter strikes the surface of the cathode carbon block, the flail hammer cutter will select a rotation angle to realize real-time position adjustment according to the different strength of the contact surface, which can avoid the base material deformation problems caused by side bending, distortion and draft angle due to the deformation of the cathode carbon block, thereby reducing economic losses;

[0024] Through the arrangement of the second support frames in the "loop" shape, since the loop-shaped structure has high overall stability, it can effectively bear the vibration and impact force generated during the operation of the flail hammer drum, thereby prolonging the service life of the first cleaning mechanism and reducing the maintenance cost.

[0025] Further, when each of the flail hammer cutters rotates to the maximum angle, each of the flail hammer cutters abuts against the adjacent fixing seat.

[0026] Further, the third cleaning mechanism comprises a third support frame and two end mills with identical structures, the length direction of the third support frame is consistent with the length direction of the first conveying mechanism, a third guide rail is arranged at the top of the third support frame, the third guide rail is a ball guide rail, both of the two end mills are slidably connected with the third guide rail, a second conveying mechanism is arranged on the third guide rail between the two end mills, and the other end of the second conveying mechanism extends to one side of the first guide rail.

[0027] Through the above technical solution, the calcined layer on both sides of the cathode carbon block along its length can be cleaned simultaneously by setting up the third cleaning mechanism, thereby accelerating the cleaning efficiency.

[0028] Furthermore, the feeding mechanism and the unloading mechanism have the same structure, and the feeding mechanism and the unloading mechanism have opposite conveying directions;

[0029] The feeding mechanism includes a fourth support frame, a primary conveying component, and a secondary conveying component. The fourth support frame has the same structure as the first support frame. Two parallel fourth guide rails are arranged along the length direction of the fourth support frame. The primary conveying component is mounted on the fourth guide rails via multiple sliding mechanisms, and the fourth guide rails are ball bearing guide rails. The primary conveying component is equipped with a first driving component for driving the primary conveying component to move along the fourth guide rails. The secondary conveying component includes a support arm, a movable arm, and a second driving component. The support arm is mounted on top of the primary conveying component via multiple screw lifts. The movable arm is slidably mounted on the support arm. The second driving component is used to drive the movable arm to move along the length direction of the support arm, and the length direction of the support arm is consistent with the length direction of the fourth guide rails.

[0030] Through the above technical solution, by setting up the support arm, the movable arm can move left and right along the support arm, thereby shortening the length of the movable arm, reducing the structural difficulty and volume of the overall device, and thus reducing costs.

[0031] Furthermore, the centering mechanism includes a fifth support frame, a first push plate, and two second push plates. The fifth support frame and the first conveying mechanism are aligned in length. Two identical cathode carbon block support blocks are provided at the top of the fifth support frame along its width direction. Each cathode carbon block support block has a first notch on both sides in its width direction, making the cathode carbon block support block wedge-shaped. Each cathode carbon block support block has a roller at one end near the feeding mechanism. Each roller is rotatably connected to the fifth support frame, and the end face of each roller is located at the top of the fifth support frame.

[0032] The first push plate is slidably disposed on the fifth support frame, and the first push block is disposed along the length direction of the fifth support frame; the two second push plates are respectively disposed at both ends of the length direction of the first push plate, and are slidably connected to the first push plate.

[0033] A third drive assembly and a fourth drive assembly for driving the first push plate and the two second push plates to move are respectively provided on the side surface of the first push plate away from the roller.

[0034] Through the above technical solution, by setting the rollers, when the cathode carbon block is on the cathode carbon block support block on the fifth support frame, when the first push plate pushes the cathode carbon block to move, the side surface of the cathode carbon block will abut against the rollers, and at this time the circumferential surface of the rollers abuts against the cathode carbon block, thereby avoiding damage to the cathode carbon block and reducing economic losses.

[0035] Both the third and fourth drive components are located on the side facing away from the cathode carbon block. When the position of the cathode carbon block is adjusted by the first and second push plates, the first push plate can block some dust, thereby reducing the impact of dust on the centering mechanism, extending the service life of the centering mechanism and reducing maintenance costs.

[0036] Furthermore, the sliding guide seat is arranged along the length direction of the first conveying mechanism, and each sliding guide seat has a stop at both ends of its length direction. The stop is arranged along the length direction of the sliding guide seat, and the lower part of the stop is provided with a second limiting groove that matches the first guide rail. The other end of each stop is provided with a chamfer, so that the width of the chamfered section of each stop gradually decreases, and the width of the end of the stop away from the sliding guide seat is smaller than the width of the end closer to the sliding guide seat.

[0037] With the above technical solution, by setting the stop block, the stop block will move along the first guide rail before the sliding guide seat moves, and the stop block with two chamfers is more likely to scrape off the dust, thereby reducing the amount of dust entering the sliding guide seat and extending the service life of the device.

[0038] The above solution has the following advantages:

[0039] 1. By setting up the first cleaning mechanism, the calcined layer on two opposite side faces in the width direction of the cathode carbon block can be cleaned. After cleaning, the position of the cathode carbon block is adjusted by the flipping mechanism. After adjustment, the other two side faces in the width direction of the cathode carbon block are cleaned by the second cleaning mechanism. Finally, the calcined layer on both side faces in the length direction is cleaned by the third cleaning mechanism. Thus, the calcined layer on each part of the cathode carbon block is cleaned. Moreover, the entire cleaning process, from the centering, feeding, fixing, cleaning and unloading of the cathode carbon block, does not require manual transmission, flipping and cleaning, thereby speeding up the cleaning efficiency. Through the synchronous movement of the first fixing mechanism and the second fixing mechanism, when the first fixing mechanism moves the carbon block to clean, the second fixing mechanism will also move another carbon block to clean, thereby speeding up the cleaning efficiency of this cleaning system.

[0040] 2. Through the arrangement of the ball guide rail, since the rolling friction of the ball guide rail is much lower than the sliding friction of the linear guide rail, which can significantly reduce energy loss and wear. Further, in a dusty environment, the ball guide rail has low lubrication requirements, and is not prone to jamming or wear caused by dust accumulation, so as to prolong the service life and reduce maintenance requirements. Moreover, the ball guide rail can bear larger radial and axial loads, and further, in long-distance movement, the ball guide rail can stably support heavy objects, reduce deformation or damage caused by uneven loads, so as to prolong the service life and reduce maintenance requirements; through the arrangement of the first bearing and the second bearing, when the first fixing mechanism and the second fixing mechanism move along the first guide rail, the bearings can effectively prevent pollutants such as dust and sand particles from entering the interior of the bearings, thus prolonging the service life of each structure and reducing the maintenance cost;

[0041] 3. Through the arrangement of the milling drum and the flail hammer drum, when cleaning the roasted layer on the surface of the cathode carbon block, the milling drum serves as the first cleaning pass. The milling drum with point breaking characteristics can clean 80-90% of the roasted layer, which can improve the cleaning efficiency of the cathode carbon block. After the first cleaning pass, the flail hammer drum is used for the second cleaning pass. Since the flail hammer cutter and the flail hammer roller are flexibly connected, when the flail hammer cutter swings and strikes the surface of the cathode carbon block, the flail hammer cutter will select a rotation angle to realize real-time position adjustment according to the different strength of the contact surface, which can avoid the problems of base material deformation caused by side bending, torsion and draft angle caused by the deformation of the cathode carbon block, so as to reduce economic losses; through the arrangement of the second support frame in a "loop" shape, since the loop-shaped structure has high overall stability, it can effectively bear the vibration and impact force generated during the operation of the flail hammer drum, thus prolonging the service life of the first cleaning mechanism and reducing the maintenance cost;

[0042] 4. Through the arrangement of the support arm, the moving arm can move left and right along the support arm, thereby shortening the length of the moving arm, reducing the structural difficulty and volume of the whole device, and thus reducing the cost;

[0043] 5. Through the arrangement of the rollers, when the cathode carbon block is placed on the cathode carbon block support block on the fifth support frame and the first push plate pushes the cathode carbon block to move, the side vertical surface of the cathode carbon block will abut against the rollers, and at this time, the circumferential surface of the rollers abuts against the cathode carbon block, so that damage to the cathode carbon block can be avoided, thus reducing economic losses; the third driving assembly and the fourth driving assembly are both arranged on the side facing away from the cathode carbon block. When the position of the cathode carbon block is adjusted through the first push plate and the second push plate, the first push plate can block part of the dust, thereby reducing the influence of dust on the centering mechanism, and thus prolonging the service life of the centering mechanism and reducing the maintenance cost;

[0044] 6. By setting the stop, the stop will move along the first guide rail before the sliding guide seat moves. The stop with two chamfers makes it easier to scrape off the dust, thereby reducing the amount of dust entering the sliding guide seat and extending the service life of the device.

Detailed Implementation

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] In a specific embodiment, such as Figures 1-10 As shown, the automatic cathode carbon block cleaning system includes a first conveying mechanism 1 and a first fixing mechanism 2 and a second fixing mechanism 3 respectively disposed at one end and the middle of the first conveying mechanism 1 along its length. The first fixing mechanism 2 and the second fixing mechanism 3 are both used to fix the cathode carbon block and synchronously carry the cathode carbon block to move along the length of the first conveying mechanism 1 in the same direction.

[0059] A feeding mechanism 4 is provided on one side of the width direction of the first conveying mechanism 1, and the feeding mechanism 4 is located at one end of the length direction of the first conveying mechanism 1. The feeding mechanism 4 is used to convey the cathode carbon block to the first fixing mechanism 2.

[0060] In the second fixing mechanism 3, the first conveying mechanism 1, which is close to the first fixing mechanism 2, is provided with a first cleaning mechanism 5 on both sides in the width direction. The two first cleaning mechanisms 5 are used to clean the opposite two vertical surfaces in the width direction of the cathode carbon block.

[0061] A flipping mechanism 6 is provided on one side of the width direction of the first conveying mechanism 1, and the flipping mechanism 6 is located on the side of the first cleaning mechanism 5 away from the feeding mechanism 4. The flipping mechanism 6 is used to remove the cathode carbon block on the second fixing mechanism 3, flip the cathode carbon block 90° and place it on the second fixing mechanism 3.

[0062] The second fixing mechanism 3 has a second cleaning mechanism 7 on each side of the first conveying mechanism 1 on the side away from the first cleaning mechanism 5 in the width direction. The two second cleaning mechanisms 7 are used to clean the other two opposite vertical surfaces in the width direction of the cathode carbon block.

[0063] A third cleaning mechanism 8 is provided at the other end of the length direction of the first conveying mechanism 1, and the third cleaning mechanism 8 is located on one side of the width direction of the first conveying mechanism 1. The third cleaning mechanism 8 is used to clean the opposite two vertical surfaces of the cathode carbon block in the length direction.

[0064] A feeding mechanism 9 is provided between the first conveying mechanism 1 and the third cleaning mechanism 8. The feeding mechanism 9 is used to convey the cathode carbon block on the second fixing mechanism 3 to the third cleaning mechanism 8.

[0065] The first cleaning mechanism 5 cleans the calcined layer on two opposite side faces of the cathode carbon block in the width direction. After cleaning, the position of the cathode carbon block is adjusted by the flipping mechanism 6. After adjustment, the second cleaning mechanism 7 cleans the other two side faces of the cathode carbon block in the width direction. Finally, the third cleaning mechanism 8 cleans the calcined layer on both side faces in the length direction, thereby cleaning the calcined layer on every part of the cathode carbon block. The entire cleaning process, from centering, feeding, fixing, cleaning and unloading of the cathode carbon block, does not require manual transmission, flipping and cleaning, thus speeding up the cleaning efficiency. The first fixing mechanism 2 and the second fixing mechanism 3 move synchronously in the same direction. When the first fixing mechanism 2 moves the carbon block for cleaning, the second fixing mechanism 3 also moves another carbon block for cleaning, thereby speeding up the cleaning efficiency of this system.

[0066] The automatic cathode carbon block cleaning system also includes a centering mechanism 10, which is located at one end of the feeding port of the feeding mechanism 4. The centering mechanism 10 is used to receive cathode carbon blocks and adjust the position of the cathode carbon blocks.

[0067] The first conveying mechanism 1 includes a first support frame 101 and two first guide rails 102. The two first guide rails 102 are arranged in parallel on the top of the first support frame 101. Both first guide rails 102 are arranged along the length of the first support frame 101, and each first guide rail 102 is a ball bearing guide rail. The specific structure of the ball bearing guide rail is prior art and will not be described in detail here. The ball bearing guide rail has significantly reduced energy loss and wear because its rolling friction is much lower than that of the linear guide rail. In dusty environments, the ball bearing guide rail has lower lubrication requirements and is less prone to jamming or wear due to dust accumulation, thus extending its service life and reducing maintenance requirements. Furthermore, the ball bearing guide rail can withstand greater radial and axial loads, thus providing stable support for heavy objects during long-distance movement and reducing deformation or damage caused by uneven loads, thereby extending its service life and reducing maintenance requirements. The specific structure and connection method of the first conveying mechanism 1 are prior art and will not be described in detail here.

[0068] The first fixing mechanism 2 and the second fixing mechanism 3 are both slidably engaged with the first guide rail 102 through multiple sliding mechanisms; each sliding mechanism includes a sliding guide seat 11 and multiple first bearings 12. Each sliding guide seat 11 is fixedly installed at the bottom of the corresponding first fixing mechanism 2 or the second fixing mechanism 3. A first limiting groove 13 is provided in the middle of the lower part of each sliding guide seat 11. The width of the first limiting groove 13 is the same as that of the first guide rail 102. Multiple first bearings 12 are respectively arranged on both sides of the width direction of the first limiting groove 13. A first connecting shaft is fixedly provided on the inner ring of each first bearing 12. The other end of each first connecting shaft is fixedly connected to the corresponding sliding guide seat 11. The outer curved surface of the outer ring of each first bearing 12 abuts against the side surface of the first guide rail 102. Each first bearing 12 is a ball bearing.

[0069] The first support frame 101 includes a top support plate and a bottom support plate. The bottom support plate is provided with a plurality of first mounting parts for fixing. The top support plate is set above the bottom support plate by a plurality of support beams. The first guide rail 102 is set on the top of the top support plate.

[0070] Each sliding guide seat 11 has a reverse hook plate 14 on its side surface. The reverse hook plate 14 is vertically arranged and its lower part extends to the bottom of the sliding guide seat 11. Each reverse hook plate 14 has a second bearing 15 on its side surface near the first guide rail 102. The inner ring of each second bearing 15 is fixedly connected to the corresponding reverse hook plate 14 through a second connecting shaft. The outer curved surface of the outer ring of each second bearing 15 abuts against the bottom of the supporting top plate. Each second bearing 15 is a ball bearing.

[0071] With the first bearing 12 and the second bearing 15 in place, when the first fixing mechanism 2 and the second fixing mechanism 3 move along the first guide rail 102, the bearings can effectively prevent dust, sand and other contaminants from entering the bearing interior, thereby extending the service life of each structure and reducing maintenance costs.

[0072] The first cleaning mechanism 5 includes a support base 501 and two second support frames 502. The support base 501 is provided with multiple second mounting components for fixing. The width direction of the support base 501 is consistent with the length direction of the first conveying mechanism 1. The two second support frames 502 are respectively located on both sides of the support base 501 in the width direction. Both second support frames 502 are arranged in a "U" shape. A milling drum 16 and a hammer drum 17 are respectively provided on the side faces of the two support frames closest to the first conveying mechanism 1. Each support frame has a drive motor 18 that is linked to the milling drum 16 and the hammer drum 17. A power head box is fixedly installed on the top of the support base 501. The two ends of the power head box are slidably connected to the second support frames 502. The power head box is used to drive the second support frames 502 to move the milling drum 16 and the hammer drum 17. The distance between the two milling drums 16 in opposite positions in the first cleaning mechanism 5 can be adjusted according to actual needs by controlling the two power head boxes. The specific adjustment method is existing technology and will not be elaborated here.

[0073] The hammer drum 17 includes a hammer roller 19 and multiple hammer assemblies. The multiple hammer assemblies are arranged in a spiral shape along the outer curved surface of the hammer roller 19. Each hammer assembly includes a fixed seat 20 and a hammer blade 21. Each fixed seat 20 is fixedly installed on the hammer roller 19. One end of each hammer blade 21 is flexibly connected to the corresponding fixed seat 20, and the end of each hammer blade 21 away from the fixed seat 20 is arranged in an arc shape.

[0074] With the milling drum 16 and the hammer drum 17, when cleaning the calcined layer on the surface of the cathode carbon block, the milling drum 16 serves as the first cleaning. The milling drum 16, with its point-destructive characteristics, can clean 80-90% of the calcined layer, thus improving the cleaning efficiency of the cathode carbon block. After the first cleaning, the hammer drum 17 is used for the second cleaning. Since the hammer blade 21 and the hammer roller 19 are flexibly connected, when the hammer blade 21 strikes the surface of the cathode carbon block, the hammer blade 21 will select the rotation angle according to the different strengths of the contact surface to achieve real-time position adjustment. This can avoid the problems of side bending, twisting and draft angle caused by the deformation of the cathode carbon block, thereby reducing economic losses.

[0075] With the second support frame 502 arranged in a "loop" shape, the loop-shaped structure has high overall stability, which can effectively withstand the vibration and impact force generated by the hammer drum 17 during operation, thereby extending the service life of the first cleaning mechanism 5 and reducing maintenance costs.

[0076] When each hammer cutter 21 rotates to the maximum angle, each hammer cutter 21 abuts against the adjacent fixing seat 20.

[0077] The third cleaning mechanism 8 comprises a third support frame 801 and two face mills 802 with identical structures. The specific structure and installation mode of the face mills 802 belong to the prior art, and will not be elaborated here. The length direction of the third support frame 801 is consistent with the length direction of the first conveying mechanism 1. A third guide rail 22 is arranged at the top of the third support frame 801, and the third guide rail 22 is a ball guide rail. Both face mills 802 are slidably connected to the third guide rail 22. A second conveying mechanism 23 is arranged on the third guide rail 22 between the two face mills 802, and the other end of the second conveying mechanism 23 extends to one side of the first guide rail 102.

[0078] Through the arrangement of the third cleaning mechanism 8, the roasted layers on the two side vertical surfaces in the length direction of the cathode carbon block can be cleaned simultaneously, thereby accelerating the cleaning efficiency.

[0079] The loading mechanism 4 and the unloading mechanism 9 have the same structure, and the conveying directions of the loading mechanism 4 and the unloading mechanism 9 are opposite. The specific structure of the loading mechanism 4 belongs to the prior art, and will not be elaborated here. The loading mechanism 4 comprises a fourth support frame 401, a primary conveying assembly 402 and a secondary conveying assembly 403. The fourth support frame 401 has the same structure as the first support frame 101. Two parallel fourth guide rails 24 are arranged along the length direction of the fourth support frame 401, and the fourth guide rails 24 are ball guide rails. The primary conveying assembly 402 is arranged on the fourth guide rails 24 through a plurality of sliding mechanisms, and the primary conveying assembly 402 is provided with a first driving assembly 25 for driving the primary conveying assembly 402 to move along the fourth guide rails 24. The secondary conveying assembly 403 comprises a support arm 403-1, a moving arm 403-2 and a second driving assembly 403-3. The support arm 403-1 is mounted on the top of the primary conveying assembly 402 through a plurality of screw lifters 26. The moving arm 403-2 is slidably arranged on the support arm 403-1. The second driving assembly 403-3 is used for driving the moving arm 403-2 to move along the length direction of the support arm 403-1, and the length direction of the support arm 403-1 is consistent with the length direction of the fourth guide rail 24.

[0080] Through the arrangement of the support arm 403-1, the moving arm 403-2 can move left and right along the support arm 403-1, thereby shortening the length value of the moving arm 403-2, further reducing the structural difficulty and volume of the whole device, and thus lowering the cost.

[0081] The centering mechanism 10 includes a fifth support frame 1011, a first push plate 1012, and two second push plates 1013. The fifth support frame 1011 and the first conveying mechanism 1 are aligned in length. Two identical cathode carbon block support blocks 27 are provided at the top of the fifth support frame 1011 along its width direction. Each cathode carbon block support block 27 has a first notch on both sides in its width direction, making the cathode carbon block support block 27 wedge-shaped. Each cathode carbon block support block 27 has a roller 28 at one end near the feeding mechanism 4. Each roller 28 is rotatably connected to the fifth support frame 1011, and the end face of each roller 28 is located at the top of the fifth support frame 1011.

[0082] The first push plate 1012 is slidably disposed on the fifth support frame 1011, and the first push block is disposed along the length direction of the fifth support frame 1011; the two second push plates 1013 are respectively disposed at both ends of the length direction of the first push plate 1012, and are slidably connected to the first push plate 1012.

[0083] On the side of the first push plate 1012 away from the roller 28, a third drive assembly 29 and a fourth drive assembly 30 are respectively provided for driving the first push plate 1012 and the two second push plates 1013 to move.

[0084] With the roller 28 in place, when the cathode carbon block is on the cathode carbon block support block 27 on the fifth support frame 1011, when the first push plate 1012 pushes the cathode carbon block to move, the side surface of the cathode carbon block will abut against the roller 28, and at this time, the circumferential surface of the roller 28 abuts against the cathode carbon block, thereby avoiding damage to the cathode carbon block and reducing economic losses. The third drive assembly 29 and the fourth drive assembly 30 are both set on the side opposite to the cathode carbon block. When the position of the cathode carbon block is adjusted by the first push plate 1012 and the second push plate 1013, the first push plate 1012 can block some dust, thereby reducing the impact of dust on the centering mechanism 10, thus extending the service life of the centering mechanism 10 and reducing maintenance costs.

[0085] The sliding guide seat 11 is arranged along the length direction of the first conveying mechanism 1. Each sliding guide seat 11 has a stop 31 at both ends along its length direction. The stop 31 is arranged along the length direction of the sliding guide seat 11. The lower part of the stop 31 is provided with a second limiting groove that matches the first guide rail 102. The other end of each stop 31 along its length direction is provided with a chamfer, so that the width of the chamfered section of each stop 31 gradually decreases, and the width of the end of the stop 31 away from the sliding guide seat 11 is smaller than the width of the end closer to the sliding guide seat 11. By setting the stop 31, before the sliding guide seat 11 moves, the stop 31 will move along the first guide rail 102 first. The stop 31 with two chamfers is more likely to scrape off dust, thereby reducing the amount of dust entering the sliding guide seat 11 and extending the service life of the device.

[0086] Operation process: The uncleaned charcoal block is suspended on the centering mechanism. The position of the charcoal block is adjusted by the first push plate and two second push plates. After the adjustment, the charcoal block is aligned with the position of the charcoal block on the feeding mechanism and the first fixing mechanism. The feeding mechanism conveys the charcoal block to the first fixing mechanism. The first fixing mechanism first centers and fixes the charcoal block in the horizontal and vertical directions. After the alignment is completed, the horizontal alignment is canceled, and only the vertical alignment is retained. The first fixing mechanism moves the charcoal block on the first conveying mechanism and passes between the two first cleaning mechanisms. The milling drums on the two first cleaning mechanisms clean the two sides of the charcoal block in the width direction. After the cleaning is completed, the first fixing mechanism drives the charcoal block to move in the opposite direction. At this time, the swing hammer drums on the two first cleaning mechanisms clean the two sides of the charcoal block in the width direction. The charcoal block with the two opposite sides cleaned is taken away by the flipping mechanism and flipped over. After being flipped 90°, it is placed on the first fixing mechanism. At this time, the first fixing mechanism moves the charcoal block between the two first cleaning mechanisms to clean the other two sides of the charcoal block in the width direction.

[0087] While the first fixing mechanism moves the charcoal block on the first conveying mechanism, the second fixing mechanism carries another charcoal block through two second cleaning mechanisms for cleaning. The second fixing mechanism moves in the same direction as the first fixing mechanism each time and moves synchronously. The specific cleaning steps of the second fixing mechanism carrying the other charcoal block are the same as those of the first fixing mechanism. After cleaning, the charcoal block is conveyed to the unloading mechanism, which places the charcoal block on the third cleaning mechanism. The two end mills on the third cleaning mechanism clean the two sides of the charcoal block along its length. After cleaning, the charcoal block completes the cleaning of the roasted layer.
