Description

Technical Field

[0001] The present invention relates to a cathode carbon block cleaning device, specifically a combined cathode carbon block cleaning device. Background Art

[0002] In order 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, it is necessary to clean the baked layer adhered to the surface of the cathode carbon block before the baked cathode carbon block is transferred to the next process. The cleaned baked layer can also be recycled. The carbon block after cleaning the baked layer is the base material. Since the recycling prices of the base material and the baked layer are different, the recycling price of the base material is several times that of the baked layer.

[0003] Since the weight of each cathode carbon block can reach several tons, if manual cleaning is adopted, the labor intensity of workers is high, the production efficiency is low, and the working environment is seriously polluted; therefore, mechanical cleaning is usually used. In the prior art, face milling is usually adopted. Since the outer periphery of the baked layer does not have a straight and vertical edge line, the face milling will also clean the base material during the process of cleaning the baked layer, and the cleaned things will be recycled at the price of the baked layer, resulting in more economic losses. Summary of the Invention

[0004] The present invention provides a combined cathode carbon block cleaning device to solve the problems in the related technologies, and this device solves the problem of more economic losses caused by using face milling to clean the baked 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 arranged on the conveying mechanism. The feature is that the cleaning mechanism includes a milling drum and a hammer drum. The hammer drum includes a roller and multiple groups of hammer components;

[0007] Each group of the hammer components includes multiple fixing blocks spirally distributed on the outer curved surface of the roller. The adjacent fixing blocks between adjacent groups of the hammer components do not overlap each other. Each group of the hammer components further includes multiple hammer blades. Each hammer blade is rotatably installed on a corresponding fixing block of a group; on the side of each hammer blade away from the roller, there is a first notch with the same thickness as the hammer blade. One end of the hammer blade is provided with a kidney-shaped hole, and the end of the hammer blade with the kidney-shaped hole is arranged in the first notch. A fixing shaft is arranged on the fixing block, and the other end of the fixing shaft sequentially passes through the first notch and the kidney-shaped hole and extends out of the fixing block;

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

[0009] Through the above technical solution, through the arrangement of the milling drum and the hammering drum, the milling drum is the first process for cleaning the carbon block. The damage mode of the milling drum is point damage, and point damage has the advantages of high efficiency, energy saving and small reaction force. Therefore, the milling drum can quickly clean 80%-90% of the roasting layer outside the cathode carbon block. After one-time cleaning, the hammering drum is used for secondary cleaning; since the flyweight cutter is rotatably connected through the fixed shaft and the fixed block, when the flyweight cutter strikes the surface of the cathode carbon block, the flyweight cutter will select the rotation angle to achieve real-time position adjustment due to the different strengths of the contact surfaces. And because the end of the flyweight cutter used for connecting with the fixed shaft is provided with a waist-shaped hole, the flyweight cutter will not only rotate along the fixed shaft, but also move linearly along the waist-shaped hole, thereby realizing the flexible connection between the flyweight cutter and the fixed block. This can avoid the problems of bending, twisting and base material deformation caused by the draft angle due to the deformation of the cathode carbon block, thus reducing economic losses.

[0010] In addition, through the arc-shaped setting on the outer peripheral surface of the flyweight cutter, when the edge of the flyweight cutter is damaged after long-term cleaning of the carbon block surface, other positions on the arc surface can still clean the carbon block, which not only ensures the cleaning of the roasting layer on the carbon block surface, but also reduces the frequency of maintenance and replacement of the flyweight cutter, thereby improving the cleaning efficiency and reducing the cost.

[0011] Furthermore, the conveying mechanism includes a mounting base and two support components. The milling drum and the hammering drum are both installed on one end in the length direction of the corresponding support component through a fixed seat, and each fixed seat is longitudinally arranged; each support component includes two support beams arranged in parallel up and down, and the support beam located below in each support component is fixedly connected to the mounting base; a connecting piece is provided at the other end in the length direction of each support component, and each connecting piece is longitudinally arranged, so that the fixed seats, connecting pieces and two support beams on each side in the width direction of the mounting base form a loop.

[0012] Through the above technical solution, through the arrangement of the fixed seats, connecting pieces and two support beams forming a loop on each side, this structure is supported by the surrounding frame, and the loop structure has high overall stability, which can effectively withstand the vibration and impact force generated during the operation of the hammering drum, reduce the deformation caused by external forces, and thus extend the service life of the device and reduce the maintenance cost.

[0013] Further, the fixed shaft is a pin shaft, and a retaining pin is provided at the other end of the pin shaft; when the end of the kidney-shaped hole far from the fixed block abuts against the fixed shaft, there is a gap between the end of the fixed block close to the fixed block and the fixed block.

[0014] Through the above technical solution, by providing the pin shaft and the retaining pin, both the pin shaft and the retaining pin are standard parts, which can save production costs, and the structure is simple and the installation is convenient, thereby reducing the installation difficulty.

[0015] Further, a power head square box is provided on the top of the mounting base, and both ends of the power head square box are respectively arranged between two of the support beams in the corresponding support assembly, and the power head square box and each support beam are in sliding fit;

[0016] Guide rails are provided on the corresponding support assemblies at both ends of the power head square box in the width direction, and each guide rail is arranged along the length direction of the support assembly; a plurality of sliding mechanisms in sliding fit with the guide rails are respectively provided at both ends of the swinger drum in the width direction;

[0017] The sliding mechanism includes a sliding guide seat, a first bearing is arranged in the sliding guide seat, and the first bearing is in rotational fit with the sliding guide seat through a connecting shaft, and the outer curved surface of the first bearing abuts against the bottom of the guide rail;

[0018] A third notch having the same width as the guide rail is provided at the top of the sliding guide seat, and a second bearing and a third bearing are respectively provided on the sliding guide seats corresponding to both sides of the guide rail in the width direction. Both the second bearing and the third bearing are in rotational fit 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 vertical surfaces of the guide rail.

[0019] Through the above technical solution, by providing the first bearing, the second bearing and the third bearing, when the swinger drum removes the roasting layer on the carbon block, a large amount of dust will be generated. When the removed carbon block is transmitted along the length direction of the guide rail, due to the good sealing of the bearing, dust and debris can be prevented from entering, thereby reducing the need for cleaning and maintenance, and thus reducing costs.

[0020] Further, a telescopic dust cover is provided on each support assembly, one end of each telescopic dust cover in the telescopic direction passes through the corresponding fixed seat and extends outside the fixed seat, and the other end of each telescopic dust cover in the telescopic direction is fixedly installed in two of the support beams in the corresponding support assembly.

[0021] Through the above technical solution, with the provision of the telescopic dust cover, a large amount of dust will be generated when the hammer drum cleans the surface of the carbon block. At this time, the telescopic dust cover can reduce the dust entering the support assembly and the power head housing, avoiding affecting the normal use of the power head housing, thereby accelerating the cleaning efficiency of the carbon block and reducing costs.

[0022] Further, a motor is fixedly provided at the top of each of the fixed seats, and the output shaft of each motor is connected to the corresponding roller in a linkage manner.

[0023] Further, a limiting groove is provided at the bottom of the power head housing, and the limiting groove is arranged along the length direction of the power head housing. The mounting base is arranged in the limiting groove, and the width value of the mounting base is smaller than the width value of the limiting groove; limiting blocks are provided on the power head housing corresponding to both sides in the width direction of the limiting groove, each limiting block penetrates through the length of the power head housing, and a plurality of wedge-shaped blocks are arranged between the mounting base and the limiting blocks.

[0024] Through the above technical solution, with the provision of the wedge-shaped blocks, when manufacturing the power head housing and the mounting base, it is not necessary to precisely manufacture the power head housing and the mounting base, thereby simplifying the manufacturing difficulty of the power head housing and the mounting base and saving costs.

[0025] Further, a linear drive mechanism is provided in the power head housing, and the linear drive mechanism is connected to the sliding mechanism in a linkage manner; dust cover shells are respectively arranged on both side elevations in the width direction of the power head housing.

[0026] Through the above technical solution, with the provision of the dust cover shells, when the hammer drum cleans the carbon block, the dust cover shells can reduce the dust entering the sliding guide seat, thereby avoiding affecting the use of the first bearing, the second bearing and the third bearing, and improving the production efficiency and reducing costs.

[0027] Adopting the above solution, there are the following specific advantages:

[0028] 1. By setting up the milling drum and the swing hammer drum, the milling drum serves as the first process for cleaning the carbon block. The damage mode of the milling drum is point damage, which has the advantages of high efficiency, energy saving, and small reaction force. Therefore, the milling drum can quickly clean 80%-90% of the roasting layer on the outside of the cathode carbon block. After the first cleaning is completed, the swing hammer drum is used for secondary cleaning; since the swing block knife is rotatably connected through a fixed shaft and a fixed block, when the swing block knife strikes the surface of the cathode carbon block, the swing block knife will adjust its rotation angle in real time according to the different strengths of the contact surface, and because there is a waist-shaped hole at the end of the swing block knife used to connect with the fixed shaft, the swing block knife will not only rotate along the fixed shaft but also move linearly along the waist-shaped hole, thereby realizing the flexible connection between the swing block knife and the fixed block, which can avoid the problems of bending, twisting caused by the deformation of the cathode carbon block and the deformation of the base material caused by the draft angle, thus reducing economic losses;

[0029] In addition, by setting the arc shape on the outer peripheral surface of the swing block knife, when the edge of the swing block knife is damaged after long-term cleaning of the carbon block surface, other positions on the arc surface can still clean the carbon block, which not only ensures the cleaning of the roasting layer on the carbon block surface but also reduces the frequency of maintenance and replacement of the swing block knife, thereby improving the cleaning efficiency and reducing costs;

[0030] 2. By setting up the fixed seat, connecting piece, and two support beams that form a loop on each side, this structure is supported by the surrounding frame, and the figure-eight structure has high overall stability, which can effectively withstand the vibration and impact force generated during the operation of the swing hammer drum, reduce the deformation caused by external forces, thereby extending the service life of this device and reducing the maintenance cost;

[0031] 3. By setting up the pin shaft and the snap pin, both the pin shaft and the snap pin are standard parts, which can save production costs, and the structure is simple and the installation is convenient, which can reduce the installation difficulty;

[0032] 4. By setting up the first bearing, the second bearing, and the third bearing, when the swing hammer drum removes the roasting layer on the carbon block, a large amount of dust will be generated. When the cleaned carbon block is transmitted along the length direction of the guide rail, due to the good sealing of the bearing, dust and debris can be prevented from entering, thus reducing the need for cleaning and maintenance, thereby reducing costs;

[0033] 5. By setting up the telescopic dust cover, a large amount of dust will be generated when the swing hammer drum cleans the surface of the carbon block. At this time, the telescopic dust cover can reduce the dust entering the support assembly and the power head square box, avoid affecting the normal use of the power head square box, thereby accelerating the cleaning efficiency of the carbon block and reducing costs;

[0034] 6. By setting the wedge block, when manufacturing the power head square box and the mounting base, there is no need to precisely manufacture the power head square box and the mounting base, which can simplify the manufacturing difficulty of the power head square box and the mounting base, thereby saving costs.

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

Specific embodiments

[0051] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] In a specific embodiment, as Figures 1 - 13 shown, a combined cathode carbon block cleaning device includes a conveying mechanism and a cleaning mechanism arranged on the conveying mechanism. The cleaning mechanism includes a milling drum 24 and a flail drum. The milling drum 24 includes a milling drum rotating cylinder and a cutter holder and milling cutter heads detachably installed on the milling drum rotating cylinder, and the end of the milling cutter head far from the cutter holder is conical; the specific structure and connection method of the milling drum 24 both belong to the prior art and will not be elaborated here; the flail drum includes a roller 1 and multiple groups of flail components. In this specific embodiment, the roller 1 is arranged vertically;

[0053] Each set of swing hammer components includes multiple fixing blocks 2 spirally distributed on the outer curved surface of the roller 1. The adjacent fixing blocks 2 in adjacent sets of swing hammer components do not overlap with each other. Each set of swing hammer components further includes multiple swing blade cutters 3. Each swing blade cutter 3 is rotatably mounted on a fixing block 2 of the corresponding set; on the side of each swing blade cutter 3 away from the roller 1, there is a first notch 4 with the same thickness as the swing blade cutter 3. One end of the swing blade cutter 3 is provided with an oval hole 5. The end of the swing blade cutter 3 with the oval hole 5 is arranged in the first notch 4. The fixing block 2 is provided with a fixing shaft 6. The other end of the fixing shaft 6 sequentially passes through the first notch 4 and the oval hole 5 and extends outside the fixing block 2; due to the setting of the oval hole, the swing blade cutter 3 will not only rotate around the fixing shaft 6, but also move, that is, the swing blade cutter 3 approaches or moves away from the fixing block 2; the other end of the swing blade cutter 3 is provided with a second notch, so that the outer peripheral surface of the swing blade cutter 3 is arranged in an arc shape; when the roller 1 rotates, the arc surface of each swing blade cutter 3 will abut against a fixing block 2 on one side.

[0054] The cathode carbon block will first be subjected to point destruction treatment by the milling drum 24 to clean most of the roasting layer. At this time, the carbon block is then subjected to secondary cleaning by the swing hammer drum. Each swing blade cutter 3 driven by the rotation of the roller 1 is in line contact with the carbon block, and at this time, the swing blade cutter and the fixed seat are flexibly connected. When the swing blade cutter encounters a harder cathode carbon block, it will rotate, that is, the swing blade cutter will rebound. When the swing blade cutter encounters a softer roasting layer, it will not rotate, but will continue to polish and clean the roasting layer, so as to ensure that the roasting layer on the surface of the carbon block is removed cleanly, thus avoiding economic losses.

[0055] When the cutting edge of the swing blade cutter 3 is damaged due to long-term cleaning of the surface of the carbon block, other positions on the arc surface can still clean the carbon block, which not only ensures the cleaning of the roasting layer on the surface of the carbon block, but also reduces the frequency of maintenance and replacement of the swing blade cutter 3, thereby improving the cleaning efficiency and reducing the cost.

[0056] The fixing shaft 6 is a pin shaft, and a retaining pin 7 is arranged on the other end of the pin shaft; both the pin shaft and the retaining pin 7 are standard parts, which can save production costs, and have a simple structure and convenient installation, thus reducing the installation difficulty; when the end of the oval hole 5 away from the fixing block 2 abuts against the fixing shaft 6, there is a gap between the end of the fixing block 2 close to the fixing block 2 and the fixing block 2.

[0057] Such as Figure 1As shown, the conveying mechanism includes a mounting base 8 and two support components 9. The milling drum 24 and the swing hammer drum are both mounted at one end of the corresponding support component 9 in the length direction through a fixed seat 12, and each fixed seat 12 is longitudinally arranged; each support component 9 includes two support beams arranged in parallel up and down, and the support beam located below in each support component 9 is fixedly connected to the mounting base 8; a connecting piece 11 is provided at the other end of each support component 9 in the length direction, and each connecting piece 11 is longitudinally arranged, so that the fixed seats 12, the connecting pieces 11 and the two support beams on each side in the width direction of the mounting base 8 form a loop; the square structure has high overall stability, and can effectively withstand the vibration and impact force generated by the swing hammer drum 25 during operation, reduce deformation caused by external forces, thereby extending the service life of the device and reducing the maintenance cost.

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

[0059] As Figures 7 - 8 shown, the sliding mechanism includes a sliding guide seat 14. A first bearing 15 is arranged in the sliding guide seat 14. The first bearing 15 is in rotational fit 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] A third notch with the same width as the guide rail 13 is provided at the top of the sliding guide seat 14. Second bearings 16 and third bearings 17 are respectively provided on the sliding guide seats 14 corresponding to the two sides in the width direction of the guide rail 13. The second bearings 16 and the third bearings 17 are in rotational fit with the sliding guide seat 14 through connecting shafts, and the outer curved surfaces of the second bearings 16 and the third bearings 17 abut against the side vertical surfaces of the guide rail 13; when the swing hammer drum removes the roasting layer on the carbon block, a large amount of dust will be generated. When the removed carbon block is transmitted along the length direction of the guide rail 13, due to the good sealing of the bearings, dust and debris can be prevented from entering, thus reducing the need for cleaning and maintenance, and thereby reducing costs.

[0061] As Figure 1 and Figure 10As shown in the figure, each support component 9 is provided with a telescopic dust cover 18. One end of each telescopic dust cover 18 in the telescopic direction passes through the corresponding fixed seat 12 and extends outside the fixed seat 12, and the other end of each telescopic dust cover 18 in the telescopic direction is fixedly installed inside the two support beams in the corresponding support component 9. When the flail drum cleans the surface of the carbon block, a large amount of dust will be generated. At this time, the telescopic dust cover 18 can reduce the dust entering the support component 9 and the power head square box 10, avoid affecting the normal use of the power head square box 10, thereby improving the cleaning efficiency of the carbon block and reducing costs.

[0062] As Figure 10 shown, a motor 19 is fixedly arranged on the top of each fixed seat 12, and the output shaft of each motor 19 is connected to the corresponding roller 1 in a linkage manner.

[0063] As Figures 11 - 13 shown, a limiting groove is arranged at the bottom of the power head square box 10, and the limiting groove is arranged along the length direction of the power head square box 10. The mounting base 8 is arranged in the limiting groove, and the width value of the mounting base 8 is smaller than the width value of the limiting groove; limiting blocks are arranged on the power head square box 10 corresponding to both sides in the width direction of the limiting groove, and each limiting block penetrates through the length of the power head square box 10. A plurality of wedge-shaped blocks 20 are arranged between the mounting base 8 and the limiting blocks. When fixing the power head square box 10 and the mounting base 8, first, the power head square box 10 and the mounting base 8 are fixed together by a large number of bolts, and then the connection stability of the two is ensured by arranging a plurality of wedge-shaped blocks 20 between the power head square box 10 and the mounting base 8; when producing the power head square box 10 and the mounting base 8, it is not necessary to precisely produce the power head square box 10 and the mounting base 8. At this time, only by adjusting the position of the wedge-shaped block 20 with an inclined side surface can the power head square box 10 be firmly fixed on the mounting base 8, thereby simplifying the production difficulty of the power head square box 10 and the mounting base 8. After determining the good position of the wedge-shaped block 20, it is fixed on the power head square box 10 by bolts, thus saving costs.

[0064] In this specific embodiment, two dust baffle plates 23 are arranged on the top of the power head square box 10 corresponding to between the two support components 9. The two dust baffle plates 23 are symmetric about the midline in the width direction of the power head square box 10. Each dust baffle plate 23 is arranged along the length direction of the power head square box 10, and each dust baffle plate 23 is arranged in an "L" shape. The horizontal part of each dust baffle plate 23 is fixedly installed on the top of the power head square box 10, and the side surface of the vertical part of each dust baffle plate 23 abuts against the support component 9.

[0065] A linear drive mechanism 21 is provided inside the power head square box 10, and the linear drive mechanism 21 is connected to the sliding mechanism in a linkage manner. The linear drive mechanism 21 is used to drive the fixed seat 12, the connecting member 11 and the two support beams to move in a rectangular structure, thereby driving the milling drum 24 and the hammer drum to move. In this specific embodiment, the linear drive mechanism 21 is selected as an oil cylinder; dust-proof cover shells 22 are respectively arranged on the two side elevations in the width direction of the power head square box 10; when the hammer drum cleans the carbon block, the dust-proof cover shells 22 can reduce the entry of dust into the sliding guide seat 14, thereby avoiding affecting the use of the first bearing 15, the second bearing 16 and the third bearing 17, and thus improving production efficiency and reducing costs.

[0066] Operation process: Each side elevation of the carbon block will be cleaned twice. When the carbon block passes through the milling drum, the milling drum will perform the first cleaning on the side elevation of the carbon block. At this time, the milling drum will clean off a relatively thick layer of the roasting layer on the side elevation of the carbon block. That is, after being processed by the milling drum, most of the roasting layer on the side elevation of the carbon block has been cleaned off, and the first cleaning is completed at this time; then, the hammer drum continues to clean the remaining thin layer of the roasting layer on the side elevation of the carbon block. During the cleaning process of the hammer drum, the rotating roller drives the hammer cutter to rotate, and the hammer cutter removes the roasting layer on the side elevation of the carbon block during the rotation process, and the secondary cleaning is completed at this time.

[0067] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the communication inside two elements. It can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0068] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here, and the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
