Description

Technical Field

[0001] This invention relates to a cathode carbon block cleaning device, specifically a combined cathode carbon block cleaning device. Background Technology

[0002] To facilitate the assembly of cathode carbon blocks and prevent the bonded filler from falling into the electrolytic cell and affecting the quality of primary aluminum, the calcination layer bonded to the surface of the cathode carbon blocks must be cleaned before the calcined cathode carbon blocks are transferred to the next process. The cleaned calcination layer can also be recycled. The carbon blocks after the calcination layer has been cleaned are the base material. Since the recycling price of the base material is different from that of the calcination layer, the recycling price of the base material is several times that of the calcination layer.

[0003] Since each cathode carbon block can weigh several tons, manual cleaning would result in high labor intensity, low production efficiency, and severe environmental pollution. Therefore, mechanical cleaning is usually employed. Current technology typically uses end milling. However, because the outer perimeter of the calcined layer is not perfectly straight with neat edge lines, end milling will also remove the parent material during the cleaning process. The removed material is then recycled at the price of the calcined layer, resulting in significant economic losses. Summary of the Invention

[0004] In order to solve the problems in related technologies, the present invention provides a combined cathode carbon block cleaning device, which solves the problem of significant economic losses caused by the use of end face milling to clean the calcined layer in the prior art.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] A combined cathode carbon block cleaning device includes a conveying mechanism and a cleaning mechanism disposed on the conveying mechanism. The cleaning mechanism includes a milling drum and a hammer drum, wherein the hammer drum includes a roller and multiple sets of hammer assemblies.

[0007] Each set of the hammer-swing assembly includes multiple fixed blocks spirally distributed along the outer curved surface of the roller. Adjacent fixed blocks in adjacent sets of hammer-swing assemblies do not overlap. Each set of hammer-swing assembly also includes multiple hammer-swing blades, each hammer-swing blade being rotatably mounted on one of the fixed blocks in its corresponding set. Each hammer-swing blade has a first notch with the same thickness as the blade on the side away from the roller. One end of the hammer-swing blade has an oblong hole, and the end of the hammer-swing blade with the oblong hole is located in the first notch. A fixed shaft is provided on the fixed block, and the other end of the fixed shaft passes through the first notch and the oblong hole in sequence and extends out of the fixed block.

[0008] The other end of the block-throwing blade is provided with a second notch, so that the outer peripheral surface of the block-throwing blade is arc-shaped; when the roller rotates, the arc-shaped surface of each block-throwing blade will abut against the fixed block on one side.

[0009] Through the above technical solution, the milling drum and the hammer drum are used. The milling drum is the first step in cleaning the carbon block. The milling drum's destruction method is point destruction, which has the advantages of high efficiency, energy saving and small reaction force. Therefore, the milling drum can quickly clean 80%-90% of the calcined layer on the outside of the cathode carbon block. After the first cleaning, the hammer drum is used for a second cleaning. Since the hammer blade is connected to the fixed shaft and the fixed block in a rotating manner, when the hammer blade hits the surface of the cathode carbon block, the hammer blade will select the rotation angle according to the different strengths of the contact surface to achieve real-time position adjustment. Moreover, since the end of the hammer blade that is used to connect with the fixed shaft is provided with a waist-shaped hole, the hammer blade will not only rotate along the fixed shaft, but also move linearly along the waist-shaped hole, thereby achieving a flexible connection between the hammer blade and the fixed block. This can avoid the bending, twisting and deformation of the base material caused by the deformation of the cathode carbon block and the draft angle, thereby reducing economic losses.

[0010] Furthermore, by setting the arc shape on the outer periphery of the shovel blade, even when the blade breaks due to long-term cleaning of the charcoal block surface, other parts of the arc surface can still clean the charcoal block. This not only ensures the cleaning of the roasted layer on the surface of the charcoal block, but also reduces the frequency of maintenance and replacement of the shovel blade, thereby improving cleaning efficiency and reducing costs.

[0011] Furthermore, the conveying mechanism includes a mounting base and two support components. The milling drum and the hammer drum are both mounted on one end of the corresponding support component along its length via fixed seats, and each fixed seat is longitudinally arranged. Each support component includes two support beams arranged parallel to each other, and the lower support beam in each support component is fixedly connected to the mounting base. The other end of each support component along its length is provided with a connector, and each connector is longitudinally arranged, so that the fixed seats, connectors, and two support beams on each side of the mounting base along its width form a loop.

[0012] Through the above technical solution, with the fixed base, connectors and two support beams forming a loop on each side, this structure, supported by the four-sided frame, has high overall stability. This allows it to effectively withstand the vibration and impact generated by the swing hammer drum during operation, reduce deformation caused by external forces, thereby extending the service life of the device and reducing maintenance costs.

[0013] Furthermore, the fixed shaft is a pin, and a locking pin is provided on the other end of the pin; when the end of the oblong hole away from the fixed block abuts against the fixed shaft, there is a gap between the end of the fixed block closer to the fixed block and the fixed block.

[0014] The above technical solution, through the setting of pins and locking pins, both of which are standard parts, can save production costs, and the structure is simple and easy to install, thus reducing the difficulty of installation.

[0015] Furthermore, a power head box is provided on the top of the mounting base, and the two ends of the power head box are respectively disposed between the two support beams in the corresponding support assembly, and the power head box and each support beam are in a sliding fit.

[0016] Guide rails are provided on the support components at both ends of the power head box in the width direction, and each guide rail is provided along the length direction of the support component; multiple sliding mechanisms that slide with the guide rails are provided at both ends of the hammer drum in the width direction.

[0017] The sliding mechanism includes a sliding guide seat, in which a first bearing is disposed. The first bearing is rotatably engaged with the sliding guide seat via a connecting shaft, and the outer curved surface of the first bearing abuts against the bottom of the guide rail.

[0018] The top of the sliding guide seat is provided with a third notch that is the same width as the guide rail. The sliding guide seats on both sides of the guide rail in the width direction are respectively provided with a second bearing and a third bearing. The second bearing and the third bearing are rotatedly engaged with the sliding guide seat through a connecting shaft, and the outer curved surfaces of the second bearing and the third bearing abut against the side surface of the guide rail.

[0019] With the above technical solution, the setting of the first bearing, the second bearing and the third bearing will generate a lot of dust when the hammer drum removes the roasted layer on the carbon block. When the removed carbon block is transmitted along the length of the guide rail, the good sealing of the bearing can prevent dust and debris from entering, thus reducing the need for cleaning and maintenance and reducing costs.

[0020] Furthermore, each of the support components is provided with a telescopic dust cover, one end of each telescopic dust cover in the telescopic direction extends through the corresponding fixed seat to the outside of the fixed seat, and the other end of each telescopic dust cover in the telescopic direction is fixedly installed in the two support beams of the corresponding support component.

[0021] Through the above technical solution, the telescopic dust cover reduces the amount of dust generated when the hammer drum cleans the surface of the carbon blocks. This reduces the amount of dust entering the support components and the power head box, thus avoiding affecting the normal use of the power head box, thereby accelerating the cleaning efficiency of the carbon blocks and reducing costs.

[0022] Furthermore, a motor is fixedly installed on the top of each of the fixed seats, and the output shaft of each motor is linked to the corresponding roller.

[0023] Furthermore, a limiting groove is provided at the bottom of the power head box, and the limiting groove is provided along the length direction of the power head box. The mounting base is disposed in the limiting groove, and the width of the mounting base is less than the width of the limiting groove. Limiting blocks are provided on the power head box on both sides of the width direction of the limiting groove, and each limiting block extends through the length of the power head box. Multiple wedge blocks are provided between the mounting base and the limiting blocks.

[0024] By using the above technical solution and the wedge-shaped block, it is not necessary to precisely manufacture the power head box and the mounting base during production. This simplifies the production of the power head box and the mounting base, thereby saving costs.

[0025] Furthermore, a linear drive mechanism is provided inside the power head box, and the linear drive mechanism is linked to the sliding mechanism; dustproof covers are respectively provided on both sides of the power head box in the width direction.

[0026] Through the above technical solution, by setting up a dust cover, when the hammer drum cleans the carbon blocks, the dust cover can reduce the amount of dust entering the sliding guide seat, thereby avoiding affecting the use of the first bearing, the second bearing and the third bearing, thus improving production efficiency and reducing costs.

[0027] The above solution has the following advantages:

[0028] 1. By setting up a milling drum and a hammer drum, the milling drum serves as the first step in cleaning the carbon block. The milling drum's destruction method is point destruction, which has the advantages of high efficiency, energy saving, and low reaction force. Therefore, the milling drum can quickly clean 80%-90% of the calcined layer on the outside of the cathode carbon block. After the first cleaning, the hammer drum performs a second cleaning. Because the hammer cutter is connected to the fixed shaft and the fixed block in a rotating manner, when the hammer cutter strikes the surface of the cathode carbon block, it will select the rotation angle according to the strength of the contact surface to achieve real-time position adjustment. Furthermore, because the end of the hammer cutter that connects to the fixed shaft is provided with an oblong hole, the hammer cutter will not only rotate along the fixed shaft but also move linearly along the oblong hole, thus achieving a flexible connection between the hammer cutter and the fixed block. This can avoid the bending, twisting, and deformation of the base material caused by the draft angle of the cathode carbon block, thereby reducing economic losses.

[0029] In addition, by setting the arc shape on the outer periphery of the shovel, when the blade breaks due to long-term cleaning of the charcoal block surface, other parts of the arc surface can still clean the charcoal block. This not only ensures the cleaning of the roasted layer on the surface of the charcoal block, but also reduces the frequency of maintenance and replacement of the shovel, thereby improving cleaning efficiency and reducing costs.

[0030] 2. With the fixed base, connectors and two support beams forming a loop on each side, this structure, supported by the surrounding frame, has high overall stability. This allows it to effectively withstand the vibration and impact generated by the swing hammer drum during operation, reducing deformation caused by external forces, thereby extending the service life of the device and reducing maintenance costs.

[0031] 3. By using pins and locking pins, both of which are standard parts, production costs can be saved. The structure is simple and easy to install, which reduces the difficulty of installation.

[0032] 4. By setting up the first bearing, the second bearing and the third bearing, a large amount of dust will be generated when the hammer drum removes the roasted layer on the carbon block. When the removed carbon block is driven along the length of the guide rail, the good sealing of the bearing can prevent dust and debris from entering, thus reducing the need for cleaning and maintenance and reducing costs.

[0033] 5. By setting up a telescopic dust cover, a large amount of dust will be generated when the hammer drum cleans the surface of the charcoal blocks. At this time, the telescopic dust cover can reduce the amount of dust entering the support components and the power head box, so as to avoid affecting the normal use of the power head box, thereby speeding up the cleaning efficiency of the charcoal blocks and reducing costs.

[0034] 6. By setting up wedge blocks, it is not necessary to precisely manufacture the power head box and mounting base during production, which simplifies the production of the power head box and mounting base and saves costs.

[0035] 7. By installing a dust cover, when the hammer drum cleans the carbon blocks, the dust cover can reduce the amount of dust entering the sliding guide seat, thereby avoiding affecting the use of the first bearing, the second bearing and the third bearing, thus improving production efficiency and reducing costs.

[0051] 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.

[0052] In a specific embodiment, such as Figures 1-13 As shown, a combined cathode carbon block cleaning device includes a conveying mechanism and a cleaning mechanism disposed on the conveying mechanism. The cleaning mechanism includes a milling drum 24 and a hammer drum. The milling drum 24 includes a milling drum cylinder and a tool holder and a milling cutter head detachably mounted on the milling drum cylinder. The end of the milling cutter head away from the tool holder is conical. The specific structure and connection method of the milling drum 24 are all prior art and will not be described in detail here. The hammer drum includes a roller 1 and multiple sets of hammer assemblies. In this specific embodiment, the roller 1 is arranged vertically.

[0053] Each set of swing hammer assemblies includes multiple fixed blocks 2 spirally distributed along the outer curved surface of the roller 1. Adjacent fixed blocks 2 in adjacent sets of swing hammer assemblies do not overlap. Each set of swing hammer assemblies also includes multiple swing blades 3, each swing blade 3 being rotatably mounted on a fixed block 2 of its corresponding set. Each swing blade 3 has a first notch 4 of the same thickness as the swing blade 3 on the side away from the roller 1. One end of the swing blade 3 has a waist-shaped hole 5, and the end of the swing blade 3 with the waist-shaped hole 5 is located in the first notch 4. A fixed shaft 6 is provided on the fixed block 2, and the other end of the fixed shaft 6 passes through the first notch 4 and the waist-shaped hole 5 in sequence and extends out of the fixed block 2. Due to the waist-shaped hole, the swing blade 3 will not only rotate around the fixed shaft 6, but also move, that is, the swing blade 3 will move closer to or away from the fixed block 2. The other end of the swing blade 3 has a second notch, so that the outer peripheral surface of the swing blade 3 is arc-shaped. When the roller 1 rotates, the arc-shaped surface of each swing blade 3 will abut against the fixed block 2 on one side.

[0054] The cathode carbon block is first subjected to point destruction treatment by the milling drum 24 to clean most of the roasted layer. Then, the carbon block is cleaned a second time by the hammer drum. Each hammer blade 3 driven by the rotation of the roller 1 is in line contact with the carbon block. At this time, the hammer blade and the fixed seat are flexibly connected. When the hammer blade encounters a harder cathode carbon block, it will rotate, that is, the hammer blade will rebound. When the hammer blade encounters a softer roasted layer, it will not rotate, but will continue to grind and clean the roasted layer, thereby ensuring that the roasted layer on the surface of the carbon block is cleaned and thus avoiding economic losses.

[0055] Even when the blade of the sling cutter 3 breaks down after long-term cleaning of the charcoal block surface, other parts of the arc-shaped surface can still clean the charcoal block. This not only ensures the cleaning of the roasted layer on the surface of the charcoal block, but also reduces the frequency of maintenance and replacement of the sling cutter 3, thereby improving cleaning efficiency and reducing costs.

[0056] The fixed shaft 6 is a pin, and a locking pin 7 is provided on the other end of the pin. Both the pin and the locking pin 7 are standard parts, which can save production costs. The structure is simple and the installation is convenient, which can reduce the installation difficulty. When the end of the oblong hole 5 away from the fixed block 2 abuts against the fixed shaft 6, there is a gap between the end of the fixed block 2 that is close to the fixed block 2 and the fixed block 2.

[0057] like Figure 1As shown, the conveying mechanism includes a mounting base 8 and two support components 9. The milling drum 24 and the hammer drum are both mounted on one end of the corresponding support component 9 along its length via fixed seats 12, and each fixed seat 12 is arranged longitudinally. Each support component 9 includes two support beams arranged parallel to each other, and the lower support beam in each support component 9 is fixedly connected to the mounting base 8. The other end of each support component 9 along its length is provided with a connector 11, and each connector 11 is arranged longitudinally, so that the fixed seats 12, connectors 11 and two support beams on each side of the width direction of the mounting base 8 form a loop. The loop-shaped structure has high overall stability, which can effectively withstand the vibration and impact force generated by the hammer drum 25 during operation, reduce deformation caused by external forces, thereby extending the service life of the device and reducing maintenance costs.

[0058] like Figure 1 , Figure 7-8 As shown, a power head box 10 is provided on the top of the mounting base 8. The two ends of the power head box 10 are respectively located between two support beams in the corresponding support components 9, and the power head box 10 and each support beam are in a sliding fit. Guide rails 13 are provided on the support components 9 at the top of the two ends of the power head box 10 in the width direction. Each guide rail 13 is arranged along the length direction of the support component 9. Multiple sliding mechanisms that are in a sliding fit with the guide rails 13 are provided at the two ends of the swing hammer drum in the width direction.

[0059] like Figure 7-8 As shown, the sliding mechanism includes a sliding guide seat 14, and a first bearing 15 is provided inside the sliding guide seat 14. The first bearing 15 is rotatably engaged with the sliding guide seat 14 through a connecting shaft, and the outer curved surface of the first bearing 15 abuts against the bottom of the guide rail 13.

[0060] The top of the sliding guide seat 14 is provided with a third notch with the same width as the guide rail 13. The sliding guide seats 14 on both sides of the guide rail 13 in the width direction are respectively provided with a second bearing 16 and a third bearing 17. The second bearing 16 and the third bearing 17 are both rotated with the sliding guide seat 14 through the connecting shaft, and the outer curved surfaces of the second bearing 16 and the third bearing 17 abut against the side surface of the guide rail 13. When the hammer drum removes the roasted layer on the carbon block, a large amount of dust will be generated. When the removed carbon block is moved along the length direction of the guide rail 13, the good sealing of the bearing can prevent dust and debris from entering, thus reducing the need for cleaning and maintenance and reducing costs.

[0061] like Figure 1 and Figure 10As shown, each support component 9 is equipped with a telescopic dust cover 18. One end of each telescopic dust cover 18 in the telescopic direction extends through the corresponding fixed seat 12 and out of the fixed seat 12. The other end of each telescopic dust cover 18 in the telescopic direction is fixedly installed in the two support beams in the corresponding support component 9. When the hammer drum cleans the surface of the carbon block, a large amount of dust is generated. At this time, the telescopic dust cover 18 can reduce the dust entering the support component 9 and the power head box 10, avoid affecting the normal use of the power head box 10, thereby speeding up the cleaning efficiency of the carbon block and reducing costs.

[0062] like Figure 10 As shown, a motor 19 is fixedly installed on the top of each fixed base 12, and the output shaft of each motor 19 is linked to the corresponding roller 1.

[0063] like Figure 11-13 As shown, a limiting groove is provided at the bottom of the power head box 10, and the limiting groove is set along the length direction of the power head box 10. The mounting base 8 is set in the limiting groove, and the width of the mounting base 8 is smaller than the width of the limiting groove. Limiting blocks are provided on the power head box 10 on both sides of the width direction of the limiting groove, and each limiting block extends through the length of the power head box 10. Multiple wedge blocks 20 are set between the mounting base 8 and the limiting blocks. When fixing the power head box 10 and the mounting base 8, the power head box 10 and the mounting base 8 are first fixed together by a large number of bolts. Then, by setting multiple wedge blocks 20 between the power head box 10 and the mounting base 8, the connection between the two is ensured to be stable. When producing the power head box 10 and the mounting base 8, it is not necessary to produce the power head box 10 and the mounting base 8 with precision. At this time, it is only necessary to adjust the position of the wedge blocks 20 with the inclined side facade to ensure that the power head box 10 is firmly fixed on the mounting base 8. This simplifies the production of the power head box 10 and the mounting base 8. After determining the good position of the wedge blocks 20, they are fixed on the power head box 10 with bolts, thereby saving costs.

[0064] In this specific embodiment, two dust baffles 23 are provided on the top of the power head box 10 between the two support components 9. The two dust baffles 23 are symmetrical along the center line of the width direction of the power head box 10. Each dust baffle 23 is arranged along the length direction of the power head box 10. Each dust baffle 23 is arranged in an "L" shape. The horizontal part of each dust baffle 23 is fixedly installed on the top of the power head box 10. The side surface of the vertical part of each dust baffle 23 abuts against the support component 9.

[0065] A linear drive mechanism 21 is provided inside the power head box 10, and the linear drive mechanism 21 is linked to the sliding mechanism. The linear drive mechanism 21 is used to drive the fixed seat 12, the connecting piece 11 and the two support beams to move in a U-shaped structure, thereby driving the milling drum 24 and the hammer drum to move. In this specific embodiment, the linear drive mechanism 21 is a hydraulic cylinder. Dustproof covers 22 are respectively provided on the two vertical surfaces in the width direction of the power head box 10. When the hammer drum cleans the carbon blocks, the dustproof covers 22 can reduce the dust entering the sliding guide seat 14, thereby avoiding affecting the use of the first bearing 15, the second bearing 16 and the third bearing 17, thereby improving production efficiency and reducing costs.

[0066] Operation process: The side surface of each charcoal block undergoes two cleaning processes. When the charcoal block passes through the milling drum, the milling drum performs the first cleaning of the side surface of the charcoal block. At this time, the milling drum removes the thicker layer of roasted material from the side surface of the charcoal block. That is, after the treatment by the milling drum, most of the roasted material layer on the side surface of the charcoal block is removed, and the first cleaning is completed. Then, the hammer drum continues to clean the thin layer of roasted material remaining on the side surface of the charcoal block. During the cleaning process of the hammer drum, the rotating roller drives the hammer blade to rotate. The hammer blade removes the roasted material layer on the side surface of the charcoal block during the rotation, and the second cleaning is completed.
