[0002] During the anode assembly process, after the anode carbon block phosphorus pig iron is cast onto the anode steel claw, a large amount of residue overflows onto the surface of the anode carbon block, forming irregular residues, such as caking residues and long strip-shaped residues, which need to be cleaned. The traditional cleaning method is manual cleaning, which not only damages the anode carbon block but also consumes a lot of time and manpower, affecting work efficiency.
[0003] Currently, there are also specialized cleaning devices. For example, CN2022212398414 discloses an automated cleaning device for iron slag from anode carbon blocks, CN2022115770564 discloses a dual-anode automatic electrolyte cleaning system and its cleaning method, CN2017112269192 discloses an electrolyte cleaning system for residual anode surfaces, and CN2021208476721 discloses a device for cleaning pig iron from electrodes used in aluminum electrolysis. The structures of these patents are all relatively complex. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an online cleaning equipment for phosphorus pig iron residue. This invention enables automated operation, reduces manual labor, has high cleaning efficiency, and a simple structure.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an online cleaning equipment for pig iron phosphate residue, including a hammering device. An anode carbon block passes through the hammering device via a conveying device. The hammering device is used to hammer the agglomerated pig iron phosphate residue on the anode carbon block, causing the pig iron phosphate residue to detach from the anode carbon block.
[0006] Based on the above, the hammering device includes a hammering arm assembly and a first position adjustment mechanism that drives the hammering arm assembly to move laterally and longitudinally. The hammering arm assembly can vibrate up and down to hammer the anode carbon block it passes through.

[0008] Based on the above, a milling device is also included, which is located downstream of the hammering device. The milling device is used to mill the elongated pig iron residue on the anode carbon block, so that the pig iron residue is removed from the anode carbon block.
[0009] Based on the above, a milling device is also included, which is located upstream of the hammering device. The milling device is used to mill the elongated pig iron residue on the anode carbon block, so that the pig iron residue is removed from the anode carbon block.
[0010] Based on the above, the milling device includes a milling motor and a second position adjustment mechanism that drives the milling motor to move laterally, longitudinally and vertically, and a milling cutter is provided on the motor shaft of the milling motor.
[0011] Based on the above, a cleaning device is also included, which is located downstream of the milling device and is used to clean the detached pig iron residue on the anode carbon block.

[0014] Based on the above, the top cantilever bracket is rotatably configured, and a baffle is provided on the side of the top cantilever bracket facing the incoming anode carbon block to limit the rotation range of the top cantilever bracket. A reset spring is also connected between the baffle and the top cantilever bracket to keep the top cantilever bracket in its initial position.
[0015] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model uses a conveying device to transport the anode carbon block to the hammering device, which can hammer away the clump-like ferrophosphate residue on the anode carbon block, thereby realizing online cleaning of the ferrophosphate residue that overflows from the surface of the anode carbon block after casting ferrophosphate. The whole process is automated, reduces manual labor, has high cleaning efficiency, and has a simple structure.

[0024] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0025] Example 1
[0026] like Figure 1 and Figure 2 As shown, an online cleaning equipment for pig iron slag includes a hammering device 1, and an anode carbon block 47 passes through the hammering device 1 via a conveying device.
[0027] The hammering device 1 is used to hammer the anode carbon block 47 to break the clump of pig iron phosphate residue, so that the pig iron phosphate residue is removed from the anode carbon block 47.
[0028] Ideally, two sets of the hammering device 1 are symmetrically arranged about the left and right sides of the conveying trajectory of the anode carbon block 47.
[0029] The conveying device is a overhead conveyor. In other embodiments, the conveying device may be other types of conveying devices, which is a conventional technology.
[0030] In this embodiment, the hammering device 1 includes a hammering arm assembly and a first position adjustment mechanism that drives the hammering arm assembly to move laterally and longitudinally. The hammering arm assembly can vibrate up and down to hammer the anode carbon block 47 that it passes through.
[0031] The first position adjustment mechanism mainly consists of a first longitudinal lead screw transmission mechanism 6 and a first transverse lead screw transmission mechanism 7. A first slide 9 is provided on the first position adjustment mechanism. The first slide 9 can move longitudinally and laterally under the drive of the first longitudinal lead screw transmission mechanism 6 and the first transverse lead screw transmission mechanism 7. This is conventional technology, and its specific structure and working principle will not be described in detail. The hammer arm assembly is mounted on the first slide 9.
[0032] The first position adjustment mechanism is set on one side of the anode carbon block conveying track via the first worktable 5.
[0033] The hammer arm assembly includes a swing arm 15 and a vibrating hammer head 16. A first support 14 is provided on the first slide table 9. The first end of the swing arm 15 is away from the conveying trajectory of the anode carbon block 47 and is bent downwards (in other embodiments, it can also be bent upwards). A rotating shaft is provided at the bend of the swing arm 15. The rotating shaft is rotatably connected to the first support 14 through a first bearing 19. The vibrating hammer head 16 is installed at the bottom of the second end of the swing arm 15. The swing arm 15 can swing up and down around the rotating shaft, thereby driving the vibrating hammer head. The anode carbon block 47 is subjected to up-and-down vibration hammering. An eccentric shaft 17, parallel to the rotating shaft, is rotatably mounted on the first support 14 via a second bearing 20. The two ends of the eccentric shaft 17 are concentric, while the middle section is eccentric. The first end of the rocker arm 18 is rotatably fitted onto the middle section of the eccentric shaft 17, and the second end of the rocker arm 18 is hinged to the first end of the swing arm 15. A power mechanism 10 is also provided on the first slide table 9. The power mechanism 10 drives the eccentric shaft 17 to rotate, causing the rocker arm 18 to drive the swing arm 15 to swing up and down. In this embodiment, the power mechanism 10 is a motor, which is connected to the eccentric shaft 17 via a belt drive mechanism.
[0034] In operation, the anode carbon block 47 is conveyed by the overhead conveyor and stops between the two sets of hammering devices 1. Then, the power mechanism 10 of the two sets of hammering devices 1 is controlled to work. The power mechanism 10 drives the corresponding eccentric shaft 17 to rotate. The corresponding eccentric shaft 17 drives the corresponding swing arm 15 to swing up and down through the corresponding rocker arm 18. In turn, the corresponding swing arm 15 drives the corresponding vibrating hammer head 16 to vibrate up and down. During this process, the position of the corresponding vibrating hammer head 16 can be adjusted by the first longitudinal screw transmission mechanism 6 and the first transverse screw transmission mechanism 7 so that each vibrating hammer head 16 can hammer the clump-type pig iron residue at different positions (between different steel claws) on the top surface of the anode carbon block 47, so that the pig iron residue can be separated from the anode carbon block 47. This realizes the online cleaning of the pig iron residue that overflows from the surface of the anode carbon block after the pig iron is poured. The whole process is automated, reducing manual labor, with high cleaning efficiency and simple structure. After the vibrating hammer head 16 finishes hammering the caking iron phosphate residue on the top surface of the anode carbon block 47, the power mechanism 10 is controlled to stop working. The overhead conveyor transports the anode carbon block 47 away and transports the next anode carbon block and stops it between the two sets of hammering devices 1. The above operation is repeated to achieve online cleaning of iron phosphate residue on the surface of the next anode carbon block. In this way, continuous online cleaning of iron phosphate residue on the surface of multiple anode carbon blocks can be achieved.
[0035] Example 2
[0036] Based on Example 1, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the online cleaning equipment for pig iron slag also includes a milling device 2, which is located downstream of the hammering device 1. The milling device 2 is used to mill the elongated pig iron slag on the anode carbon block 47, causing the pig iron slag to detach from the anode carbon block 47. Thus, the anode carbon block 47 passes through the hammering device 1 and then through the milling device 2.
[0037] Ideally, the milling device 2 is arranged symmetrically on both sides of the conveying trajectory of the anode carbon block 47.
[0038] In this embodiment, the milling device 2 includes a milling motor and a second position adjustment mechanism that drives the milling motor to move laterally, longitudinally and vertically. A milling cutter is provided on the motor shaft of the milling motor.
[0039] The second position adjustment mechanism mainly consists of a second longitudinal lead screw transmission mechanism 22, a second transverse lead screw transmission mechanism 23, and a vertical lead screw transmission mechanism 24. A lifting bracket 27 is mounted on the second position adjustment mechanism. The lifting bracket 27 can move laterally, longitudinally, and vertically under the drive of the second longitudinal lead screw transmission mechanism 22, the second transverse lead screw transmission mechanism 23, and the vertical lead screw transmission mechanism 24. This is conventional technology, and its specific structure and working principle will not be elaborated further. The milling motor is mounted on the lifting bracket 27, and a milling cutter 33 is mounted on the motor shaft of the milling motor.
[0040] The second position adjustment mechanism is set on one side of the conveying trajectory of the anode carbon block 47 via the second worktable 21.
[0041] Thus, in operation, the anode carbon block 47 is first hammered by two sets of hammering devices 1, following the same process as in Embodiment 1, and will not be repeated here. The anode carbon block 47 is then transported by the overhead conveyor and stopped between the two sets of milling devices 2. Then, the milling motors of the two sets of milling devices 2 are controlled to work, and the corresponding milling motors drive the corresponding milling cutters 33 to rotate at high speed, so that the corresponding milling cutters 33 mill the long strip-shaped phosphate pig iron residue on the top surface of the anode carbon block 47. During this process, the position of the corresponding milling cutter 33 can be adjusted by the second longitudinal lead screw transmission mechanism 22, the second transverse lead screw transmission mechanism 23 and the vertical lead screw transmission mechanism 24, so that each milling cutter 33 can mill the long strip-shaped phosphate pig iron residue at different positions (between different steel claws) on the top surface of the anode carbon block 47, so that the phosphate pig iron residue is removed from the anode carbon block 47, thereby improving the residue cleaning effect. After the milling cutter 33 finishes milling the elongated iron phosphate residue on the top surface of the anode carbon block 47, the milling motor is stopped, the overhead conveyor transports the anode carbon block 47 away, and the next anode carbon block is transported and stopped between the two sets of hammering devices 1. The above operation is repeated to achieve online cleaning of iron phosphate residue on the surface of the next anode carbon block. In this way, continuous online cleaning of iron phosphate residue on the surface of multiple anode carbon blocks can be achieved.
[0042] Example 3
[0043] like Figure 1 and Figure 3 As shown, based on Embodiments 1 and 2, the online cleaning equipment for pig iron slag further includes a cleaning device 3. The cleaning device 3 is located downstream of the milling device 2 and is used to clean away the pig iron slag that has detached from the anode carbon block 47. The anode carbon block 47 then passes sequentially through the hammering device 1, the milling device 2, and the cleaning device 3.
[0044] Ideally, the cleaning device 3 is arranged in two sets symmetrically about the conveying trajectory of the anode carbon block 47.
[0045] Specifically, the cleaning device 3 includes a side cantilever bracket 34 and a top cantilever bracket 35; the side cantilever bracket 34 and the top cantilever bracket 35 are set on one side of the conveying trajectory of the anode carbon block 47 via a third worktable; a side cleaning motor 37 is mounted on the side cantilever bracket 34, and a side cleaning brush head 38 for cleaning the side of the anode carbon block 47 is provided on the motor shaft of the side cleaning motor 37; a top cleaning motor 39 is mounted on the top cantilever bracket 35. A top surface cleaning brush head 40 is provided on the motor shaft of 39 to clean the top surface of the anode carbon block 47. The top surface cantilever bracket 35 is rotatably mounted on the third workbench. A baffle 42 is provided on the third workbench. The baffle 42 blocks the top surface cantilever bracket 35 on the side facing the anode carbon block 47 to limit the rotation range of the top surface cantilever bracket 35. A return spring 43 is also connected between the third workbench and the top surface cantilever bracket 35 to keep the top surface cantilever bracket 35 in its initial position.
[0046] In operation, after the anode carbon block 47 is cleaned by the hammering device 1 and the milling device 2 in sequence, it slowly passes between the two sets of cleaning devices 3 via the overhead conveyor. The side cleaning motor 37 drives the side cleaning brush head 38 to rotate at high speed to clean the side of the anode carbon block 47 as it passes. At the same time, the top cleaning motor 39 drives the top cleaning brush head 40 to rotate at high speed to clean the top surface of the anode carbon block 47 as it passes. The cleaning device 3 can then remove the phosphorus pig iron residue that adheres to the top and side surfaces of the anode carbon block 47 after being cleaned by the hammering device 1 and the milling device 2, resulting in a more thorough cleaning and better cleaning effect.
[0047] The process of the anode carbon block 47 passing through the side cleaning brush head 38 and the top cleaning brush head 40 is similar to the process of a car passing through the brush of an automatic car wash machine. Moreover, when the top cantilever bracket 35 contacts the steel claw on the anode carbon block 47, the top cantilever bracket 35 is squeezed and will be passively rotated so that the anode carbon block 47 can pass smoothly through the two sets of cleaning devices 3.
[0048] It should be noted that in other embodiments, the positions of the hammering device 1 and the milling device 2 can be interchanged, that is, the milling device 2 is located upstream of the hammering device 1, the cleaning device 3 is located downstream of the hammering device 2, and the anode carbon block 47 passes through the milling device 2 first, then through the hammering device 1, and finally through the cleaning device 3.
[0049] In some embodiments, a residue collection device is also included, which is disposed below the cleaning device 3 for collecting residue swept off the anode carbon block.
[0050] The residue collection device includes a belt conveyor 4, which is positioned directly below the cleaning device 3 along the conveying direction of the anode carbon block 47. The belt conveyor 4 is used to catch the residue swept off the anode carbon block 47 and transport the residue away.
[0051] A hopper 48 for collecting phosphate pig iron residue is provided on one side of the output end of the belt conveyor 4. The belt conveyor 4 can be replaced by a chain plate conveyor or other similar conveyors.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
