Description

Technical Field

[0001] The present invention relates to the technical field of conveyor line cleaning, and specifically provides a cleaning mechanism for a pre-baked anode conveyor line. Background Art

[0002] Pre-baked anodes are key materials in aluminum electrolysis production, used for conducting electricity and participating in electrochemical reactions. They are made from raw materials such as petroleum coke and coal tar pitch, and are processed through processes such as forming and roasting, having high strength, high electrical conductivity, and good thermal shock resistance.

[0003] The pre-baked anode conveyor line is a key logistics system in aluminum electrolysis production, playing a core role in efficiently connecting production processes, ensuring anode quality, and improving the automation level. During the operation of the pre-baked anode conveyor line, regularly cleaning the conveyor rollers is a necessary maintenance measure, directly affecting production efficiency, equipment life, and product quality.

[0004] The pre-baked anode conveyor line conveys pre-baked anodes through conveyor rollers. When cleaning the pre-baked anodes during the conveying process, it is necessary to lift the pre-baked anodes to separate them from the conveyor rollers, and then clean the pre-baked anodes. The dirt falling from the pre-baked anodes during cleaning and the dirt adhering to the roller surfaces during the conveying of the pre-baked anodes by the conveyor rollers will both reduce the friction force, resulting in the pre-baked anodes slipping and running off track during conveying, which may cause jamming, collisions, and even damage to the edges of the pre-baked anodes. Moreover, the hard particles (such as residual anode debris) on the side walls of the conveyor rollers will accelerate the wear of the roller surfaces and even scratch the bottom of the anodes, requiring frequent replacement of the conveyor rollers and increasing the maintenance cost.

[0005] Therefore, there is an urgent need for a cleaning mechanism for a pre-baked anode conveyor line to automatically clean the conveyor line regularly. Summary of the Invention

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Refer to Figure 1 , a cleaning mechanism for a pre-baked anode conveying line. The conveying line includes two frames 1. Between the two frames 1, conveying rollers 2 are rotatably connected and evenly arranged along the length direction thereof. A driving part for driving the conveying rollers 2 is provided on one of the frames 1. The driving part includes a motor installed on one of the frames 1 and a sprocket chain drivingly connected between multiple conveying rollers 2. The motor is connected to one of the conveying rollers 2. When the motor drives the conveying roller 2 connected thereto to rotate, this conveying roller 2 drives the remaining conveying rollers 2 to rotate synchronously through the sprocket chain, thereby driving the conveying rollers 2 to convey the pre-baked anode 6 (the specific structure diagram of the driving part is not shown in the figure and is all existing structures). A cleaning mechanism is provided on the two frames 1. The cleaning mechanism includes a scraping and cleaning part 3, a material guiding part 4, and a pushing and supporting part 5 installed between the two frames 1.

[0038] Refer to Figure 1 And Figure 2 , the scraping and cleaning part 3 includes moving frames 30 provided on the opposite surfaces of the two frames 1. A cleaning and scraping assembly 31 that adaptively abuts against the side wall of the conveying roller 2 and cleans the dirt adhered to the side wall thereof is sleeved on the conveying roller 2. A driving assembly 32 for driving the moving frame 30 is installed on the frame 1. The material guiding part 4 includes a material guiding plate 40 installed between the two frames 1 and located below the conveying roller 2. The material guiding plate 40 is in an inverted V shape to facilitate the discharge of the dirt that falls on it when the conveying roller 2 is cleaned. A scraping assembly 41 for cleaning the top of the material guiding plate 40 is provided at the top of the material guiding plate 40. When the cleaning and scraping assembly 31 is reset after cleaning the surface of the conveying roller 2, the scraping assembly 41 is driven by a traction member 42 provided thereon to scrape the remaining dirt on the material guiding plate 40, thereby preventing the dirt removed and dropped from the conveying roller 2 from accumulating on the material guiding plate 40 and affecting the discharge of the dirt.

[0039] Refer to Figure 1 And Figure 6, the pushing and supporting part 5 includes a hydraulic cylinder 50 fixedly installed between two frames 1 through a base. The telescopic end of the hydraulic cylinder 50 slides through the material guiding plate 40 and is installed with a supporting seat 51. An auxiliary supporting component 52 is arranged between the bottom of the supporting seat 51 and the two frames 1. When the supporting seat 51 jacks up the pre-baked anode 6, the driving component 32 locks the auxiliary supporting component 52 through a locking component 53 arranged thereon. The position of the pushing and supporting part 5 is the cleaning station.

[0040] During operation, the pre-baked anode 6 is placed on the conveyor line. The driving part drives the conveyor roller 2 to rotate to convey the pre-baked anode 6. When the pre-baked anode 6 moves to the cleaning station, the pushing and supporting part 5 jacks up and supports the pre-baked anode 6, so that the bottom of the pre-baked anode 6 is separated from the conveyor roller 2. The attached dust, residual pitch or oxide layer on the pre-baked anode 6 is cleaned by an existing cleaning device. At this time, the dust, residual pitch or oxide layer cleaned on the pre-baked anode 6 directly falls on the conveyor roller 2 and the material guiding plate 40. Then the pushing and supporting part 5 moves down to place the pre-baked anode 6 on the conveyor roller 2, and the conveyor roller 2 continues to convey the pre-baked anode 6. However, the dust, residual pitch or oxide layer at the bottom of the pre-baked anode 6 is easily adhered to the surface of the conveyor roller 2.

[0041] When the conveyor roller 2 rotates, the cleaning and scraping component 31 does not contact the surface of the conveyor roller 2 to avoid abrasion of the surface of the conveyor roller 2. When the conveyor roller 2 needs to be cleaned, the conveyor line stops conveying, and the driving component 32 drives the cleaning and scraping component 31 to move. The cleaning and scraping component 31 adaptively fits with the surface of the conveyor roller 2. Under the driving action of the driving component 32, the cleaning and scraping component 31 moves along the axial direction of the conveyor roller 2 to clean the side wall of the conveyor roller 2. The cleaned dirt directly falls on the material guiding plate 40, preventing the dirt on the surface of the conveyor roller 2 from reducing the friction force, resulting in slipping or deviation of the pre-baked anode 6 during conveying, and the hard particles on the surface of the conveyor roller 2 accelerating the wear of the surface of the conveyor roller 2 and increasing the maintenance cost. At the same time, it also improves the convenience and cleaning efficiency of cleaning the conveyor roller 2 of the conveyor line.

[0042] And when the cleaning and scraping component 31 resets, it also drives the scraping component 41 to scrape the residual dirt on the material guiding plate 40 to avoid the dirt accumulating on the material guiding plate 40 and being difficult to discharge smoothly.

[0043] Refer to Figure 1 、 Figure 2 And Figure 5, the cleaning and scraping assembly 31 includes two pushing rings 310 sleeved on the conveying roller 2 and symmetrically arranged along its axial direction. The pushing rings 310 are fixedly installed on the corresponding moving frames 30. On the side of the pushing ring 310 facing away from the frame 1, a supporting cover 311 is fixedly installed. Symmetrically arranged cleaning members 312 that slide radially along the pushing ring 310 are adaptively and slidably connected to both the supporting cover 311 and the pushing ring 310. The supporting cover 311 is in an inverted U shape, so that when the pushing ring 310 moves towards the corresponding frame 1, the dirt cleaned by the cleaning members 312 falls downward. A pushing and disengaging member 313 is installed on the frame 1, and the pushing and disengaging member 313 is used to drive the cleaning members 312 to disengage from the surface of the conveying roller 2 when the pushing ring 310 moves towards the corresponding frame 1.

[0044] Refer to Figure 1 , Figure 2 and Figure 5 , the cleaning member 312 includes an arc-shaped plate 340 slidably connected in the supporting cover 311. One end of the arc-shaped plate 340 away from the pushing ring 310 is tapered and a scraping head 341 is installed. A discharge port is opened at the lower end of the arc-shaped plate 340, so that the dirt scraped by the scraping head 341 falls downward. Uniformly arranged sliding grooves are opened at the ends of the pushing ring 310, and plugging grooves slidably inserted with the arc-shaped plate 340 are opened in the supporting cover 311. A return spring 342 is installed between the arc-shaped plate 340 and the sliding grooves and the plugging grooves.

[0045] When the cleaning member 312 is not working, the pushing and disengaging member 313 pushes the cleaning member 312 not to contact the side wall of the conveying roller 2, thereby avoiding abrasion of the scraping head 341 and the conveying roller 2 when the conveying roller 2 conveys the pre-baked anode 6.

[0046] When the cleaning member 312 cleans the conveying roller 2, the driving assembly 32 drives the moving frame 30 to drive the pushing rings 310 on both sides of the conveying roller 2 to move towards the middle of the axis of the conveying roller 2. When the pushing ring 310 moves, the pushing and disengaging member 313 disengages from the cleaning member 312. The arc-shaped plate 340 drives the scraping head 341 to move towards the side wall of the conveying roller 2 under the elastic force of the return spring 342 until the scraping head 341 abuts against the side wall of the conveying roller 2. At this time, the scraping head 341 abuts against the side wall of the conveying roller 2 to clean the side wall of the conveying roller 2. The pushing ring 310 drives the arc-shaped plate 340 and the scraping head 341 to move along the axial direction of the conveying roller 2, scraping and cleaning the dirt on the side wall of the conveying roller 2 until the scraping heads 341 on both sides of the same conveying roller 2 abut against each other, realizing a comprehensive cleaning of the surface of the conveying roller 2.

[0047] Refer to Figure 5, a plurality of support rods are evenly arranged inside the arc-shaped plate 340. A ball is installed at the end of the support rod away from the arc-shaped plate 340. When the scraping head 341 abuts against the side wall of the conveying roller 2, the ball on the support rod also abuts against the side wall of the conveying roller 2, thereby improving the stability when the arc-shaped plate 340 contacts the conveying roller 2.

[0048] Refer to Figure 1 、 Figure 2 And Figure 5 , the pushing and separating member 313 includes a plurality of jacks 330 evenly arranged along the arc-shaped trajectory of the supporting cover 311 on the side wall of the pushing ring 310. A bracket 331 corresponding to the pushing ring 310 one by one is installed on the frame 1. A push rod corresponding to the jack 330 one by one is installed on the bracket 331. A wedge 332 is installed on the push rod. A resisting rod 333 corresponding to the wedge 332 one by one is installed on the arc-shaped plate 340. The resisting rod 333 cooperates with the wedge 332 to drive the arc-shaped plate 340 away from the side wall of the conveying roller 2.

[0049] During the process of the moving frame 30 returning and moving towards the corresponding frame 1, when the pushing ring 310 approaches the pushing and separating member 313, the push rod drives the wedge 332 to insert into the corresponding jack 330. When the resisting rod 333 contacts the inclined surface of the wedge 332, the resisting rod 333 drives the arc-shaped plate 340 to move along the inclined surface of the wedge 332, so that the arc-shaped plate 340 drives the scraping head 341 away from the conveying roller 2.

[0050] Refer to Figure 1 、 Figure 2 And Figure 3 , the driving assembly 32 includes guide rails 320 symmetrically arranged along the length direction between two frames 1. Rack bars 321 are installed at both ends of the moving frame 30. The rack bars 321 on the two moving frames 30 are arranged in a staggered manner up and down. A gear 322 meshing with the rack bars 321 on the two moving frames 30 is rotatably connected to the guide rail 320. A plurality of guide rods 323 are evenly arranged between the two frames 1. Both moving frames 30 are slidably sleeved on the plurality of guide rods 323.

[0051] A cylinder (not shown in the figure) for driving the moving frame 30 connected thereto to move is installed on one of the frames 1. The cylinder pushes the moving frame 30 connected thereto to move. The moving frame 30 drives the other moving frame 30 to move through the meshing transmission between the rack bar 321 connected thereto and the gear 322, so that the two moving frames 30 move synchronously towards the middle of the conveying roller 2 or towards the two ends of the conveying roller 2.

[0052] Refer to Figure 6 And Figure 8, the top support base 51 is a rectangular block with a plurality of U-shaped grooves arranged uniformly along its length direction. The U-shaped grooves correspond to the plurality of conveying rollers 2 one by one. A discharge through groove is provided at the bottom of the U-shaped groove to prevent the dirt cleaned from the conveying roller 2 from accumulating in the U-shaped groove.

[0053] Refer to Figure 1 , Figure 6 and Figure 7 , the auxiliary support assembly 52 includes a plurality of support plates 520 fixedly installed between the frame 1 and the inclined surface of the guide plate 40. On both sides of the bottom of the top support base 51 arranged along its width direction, a plurality of inclined plates 521 are installed in an inclined shape. The plurality of inclined plates 521 are arranged uniformly along the length direction of the top support base 51. A slider 522 is installed at the end of the inclined plate 521. A chute 523 slidably connected to the slider 522 is provided on the support plate 520.

[0054] When the pre-baked anode 6 is conveyed to the cleaning station, the hydraulic cylinder 50 pushes the top support base 51 upward to push and lift the pre-baked anode 6 upward, so that the pre-baked anode 6 is separated from the conveying roller 2 for surface cleaning. During the upward movement of the top support base 51, the inclined plate 521 and the slider 522 are driven upward, and the slider 522 moves upward along the chute 523. When the driving of the hydraulic cylinder 50 stops, the driving assembly 32 drives the locking assembly 53 to lock the slider 522, so that the inclined plate 521 and the support plate 520 support the bottom of the top support base 51, thereby improving the stability of the top support base 51 when lifting the pre-baked anode 6 for cleaning.

[0055] Refer to Figure 1 , Figure 6 and Figure 7 , the locking assembly 53 includes a spring groove 530 provided on the support plate 520 and communicating with the chute 523. A moving seat is slidably connected in the spring groove 530. A first return spring 531 is fixedly installed between the moving seat and the spring groove 530. A collar 533 and two L-shaped locking rods 532 symmetrically arranged along the width direction of the moving seat are fixedly installed on the moving seat. The collar 533 is located above the L-shaped locking rods 532. A push plate 534 slidably penetrating the frame 1 is installed on the moving seat. When the moving frame 30 moves, it pushes the push plate 534 to drive the moving seat to move. A card slot 535 for limiting the collar 533 sleeved on the slider 522 is provided at a position near the top on the side of the slider 522 connected to the inclined plate 521. A locking slot 536 cooperating with the L-shaped locking rod 532 is provided at a position near the bottom on the side of the slider 522 connected to the inclined plate 521.

[0056] When the top support base 51 moves upward, the collar 533 is sleeved on the slider 522 from the top of the slider 522. The slider 522 enters between the two L-shaped locking rods 532. When rising, the driving assembly 32 drives the moving frame 30 and the pushing ring 310 to move towards the corresponding frame 1. The pushing ring 310 pushes the pushing plate 534 to drive the moving seat to stretch the first return spring 531. The moving seat drives the collar 533 to be clamped into the card slot 535, and at the same time, the L-shaped locking rod 532 is stuck in the locking slot 536, so as to lock the position of the slider 522, thereby increasing the bearing force when the top support base 51 jacks up the pre-baked anode 6.

[0057] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , the scraping component 41 includes support rails 410 fixedly installed between the two frames 1 and symmetrically arranged along its length direction. A cleaning member 411 symmetrically arranged along its length direction is slidably connected between the two support rails 410. The two cleaning members 411 are respectively located at the tops of the two inclined surfaces of the guide plate 40, and the cleaning member 411 adaptively expands and contracts to tightly abut against the top of the guide plate 40.

[0058] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 9 , the cleaning member 411 includes elastic telescopic plates 430 fixedly installed on the opposite surfaces of the two support rails 410. A scraping end 431 is fixedly installed at the lower ends of the two elastic telescopic plates 430. A guide groove 432 slidably connected to the elastic telescopic plate 430 is formed on the support rail 410, and a second return spring 433 is fixedly installed between the guide groove 432 and the elastic telescopic plate 430.

[0059] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6The traction member 42 includes a plurality of guide rods 420 fixedly installed between the opposite surfaces of the two frames 1, both ends of the guide rods 420 are arc-shaped, a locking groove 421 is provided on the top of the elastic telescopic plate 430, and a moving bar 422 is slidably connected to the bottom of the push ring 310 corresponding to the locking groove 421, and the end of the moving bar 422 is hinged with a swing block 423 through a torsion spring. A limit block for limiting the swing block 423 from swinging in a direction away from the corresponding frame 1 is also fixedly installed on the moving bar 422, and a return spring 424 is installed between the moving bar 422 and the push ring 310, and a resistance rod 425 matching the guide rod 420 is installed at one end of the moving bar 422 away from the swing block 423, and a buffer is provided between the elastic telescopic plate 430 and the guide rod 420.

[0060] When the push ring 310 moves toward the middle of the axis of the conveying roller 2, the push ring 310 drives the moving bar 422, the swing block 423 and the contact rod 425 to move, and the contact rod 425 moves along the side wall of the guide rod 420. When the swing block 423 moves to the corresponding locking groove 421 position, the swing block 423 contacts and flips with the elastic telescopic plate 430. When the push ring 310 moves, the swing block 423 moves to the side of the elastic telescopic plate 430 away from the corresponding frame 1; when the push ring 310 returns to its original position, the swing block 423 pushes the elastic telescopic plate 430 to rotate. The elastic telescopic plate 430 moves toward the corresponding side of the frame 1, and the lower end of the elastic telescopic plate 430 pushes the scraper end 431 to always contact the top of the guide plate 40 through the elastic force, so as to scrape off the dirt on the top of the guide plate 40 for discharge. When the contact rod 425 contacts the arc section of the guide rod 420, the swing block 423 and the moving bar 422 drive the swing block 423 to separate from the elastic telescopic plate 430 under the elastic force of the return spring three 424, and the elastic telescopic plate 430 is reset under the elastic force of the return spring two 433.

[0061] See also Figure 3 The buffer member includes an elastic arc block, and the side wall of the elastic expansion plate 430 is fixedly mounted with the elastic arc block. The guide rod 420 is provided with a plurality of arc holes. When the elastic expansion plate 430 is reset and moved under the elastic force of the return spring 433, the elastic arc block continuously contacts the arc holes during the movement, thereby slowing down the return speed of the elastic expansion plate 430 and preventing the elastic expansion plate 430 from colliding with the guide groove 432. It should be noted that the number of arc holes can be increased or decreased according to actual needs.

[0062] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 9, the elastic telescopic plate 430 includes a plurality of sleeves sleeved on each other from top to bottom, and a spring rod is installed between the lowermost sleeve and the uppermost sleeve, so that the elastic telescopic plate 430 always pushes the scraping end 431 against the top of the material guiding plate 40.

[0063] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 9 , a diagonal guide plate is installed on the top of the elastic telescopic plate 430, and the two diagonal guide plates are arranged in an inverted V shape. The gap between the two elastic telescopic plates 430 is blocked by the diagonal guide plate, so as to avoid the problem that it is difficult to clean the dirt scraped from the conveying roller 2 that falls on the material guiding plate 40 after passing between the two elastic telescopic plates 430.

[0064] Refer to Figures 1-9 , during operation, the pre-baked anode 6 is placed on the conveying line, and the driving part drives the conveying roller 2 to rotate to convey the pre-baked anode 6. When the pre-baked anode 6 moves to the cleaning station, the top-pushing and supporting part 5 supports and lifts the pre-baked anode 6, so that the bottom of the pre-baked anode 6 is separated from the conveying roller 2. The existing cleaning device cleans the dust, residual pitch or oxide layer attached to the pre-baked anode 6. At this time, the dust, residual pitch or oxide layer cleaned from the pre-baked anode 6 directly falls on the conveying roller 2 and the material guiding plate 40. Then the top-pushing and supporting part 5 moves down to place the pre-baked anode 6 on the conveying roller 2, and the conveying roller 2 continues to convey the pre-baked anode 6. However, the dust, residual pitch or oxide layer at the bottom of the pre-baked anode 6 is easily adhered to the surface of the conveying roller 2.

[0065] When the conveying roller 2 rotates, the cleaning and scraping component 31 does not contact the surface of the conveying roller 2 to avoid abrasion of the surface of the conveying roller 2. When the conveying roller 2 needs to be cleaned, the conveying line stops conveying, and the driving component 32 drives the cleaning and scraping component 31 to move. The cleaning and scraping component 31 adaptively fits with the surface of the conveying roller 2, and under the driving action of the driving component 32, the cleaning and scraping component 31 moves along the axial direction of the conveying roller 2 to clean the side wall of the conveying roller 2, and the cleaned dirt directly falls on the material guiding plate 40.

[0066] And when the cleaning and scraping component 31 resets, it also drives the scraping component 41 to scrape the residual dirt on the material guiding plate 40 to avoid the dirt from accumulating on the material guiding plate 40 and being difficult to discharge smoothly.
