Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical technology, and in particular to an iron collection device for an aluminum molten furnace. Background Technology
[0002] In industries such as aluminum product smelting and aluminum alloy smelting, aluminum ingots or recycled scrap aluminum need to be melted in furnaces. However, scrap aluminum often contains ferromagnetic impurities, which, if not removed in time, can seriously affect the quality of aluminum products. Specifically, they can interfere with the elemental composition of aluminum alloys, leading to substandard products or even rendering them unsuitable for sand casting.
[0003] Because the furnace is in a high-temperature environment, workers cannot work close to or deep inside it. Therefore, aluminum melt magnets must be used to remove ferromagnetic impurities. Existing aluminum melt magnets typically consist of a insert frame, a long support rod mounted on the insert frame, and an electromagnet mounted on the long support rod. During operation, a forklift holds the insert frame, and the electromagnet is inserted into the furnace to remove iron impurities.
[0004] However, existing aluminum molten metal magnet systems have several problems. Firstly, the use of electromagnets requires long-distance power connections, and forklifts easily pull on the cables during movement, affecting their normal power connection. Simultaneously, the cable insulation near the furnace is prone to aging due to high temperatures, significantly shortening the cable's lifespan. Secondly, after the forklift's forks grip the insert holder, the fit is achieved solely by the holder's own weight, without any mechanical locking or limiting structures. This connection method is highly susceptible to relative movement problems due to external forces during actual operation.
[0005] When the fork arm moves forward relative to the insert holder, the depth to which the electromagnet mounted at the end of the long support rod penetrates the furnace may unexpectedly change, potentially exceeding the preset working range and colliding with the furnace wall. This can damage the electromagnet and the furnace structure, and may also cause adsorbed iron impurities to fall back into the molten aluminum. If the fork arm moves backward relative to the insert holder, the electromagnet may unexpectedly retract, detaching from the target working area and failing to effectively adsorb iron impurities, resulting in a significant decrease in work efficiency. Secondly, frequent relative movement will cause continuous friction and wear at the contact points between the insert holder and the fork arm, shortening the equipment's lifespan. More seriously, in extreme cases, the insert holder may detach from the fork arm due to excessive displacement, causing equipment damage or even safety accidents, posing a significant hazard to work safety in high-temperature environments.
[0006] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0018] As a further improvement to the above technical solution, the top of the support platform is provided with an arc-shaped groove that matches the diameter of the cantilever branch pipe, and the inner wall of the arc-shaped groove is covered with an anti-slip pad.
[0019] The beneficial effects of this utility model are as follows: The aluminum molten furnace magnetic iron collection device provided by this utility model uses a permanent magnet magnetic head to replace the traditional electromagnet, eliminating the need for long-distance power supply connection and avoiding the problem of the forklift pulling the cable during movement, which affects the power connection. At the same time, it also prevents the insulation layer of the cable near the furnace from aging due to high temperature, greatly extending the service life of the equipment and reducing the risk of failure caused by cable problems.
[0020] In addition, the insert frame prevents the fork arm from moving forward through the front baffle. Combined with the cooperation of the chain and the buckle, the insert frame is connected to the lifting frame of the forklift, which effectively prevents the fork arm from moving backward relative to the insert frame. This forms a reliable mechanical limit and fixing structure, solving the problem caused by the relative movement of the insert frame and the fork arm. Attached Figure Description

Detailed Implementation
[0027] This utility model provides an iron-collecting device for an aluminum molten furnace. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.
[0028] Please see Figures 1 to 4 This utility model provides an iron-collecting device for an aluminum molten furnace, including an iron-collecting mechanism 4, an insert frame 1 for cooperating with a forklift arm 51, a cantilever support pipe 2 extending from front to back on the insert frame 1, and a permanent magnet attracting head 3 located at the end of the cantilever support pipe 2 away from the insert frame 1. The insert frame 1 includes a vertically arranged front baffle 11 and a rear insert plate 12, and two load-bearing beams 13 for connecting the front baffle 11 and the rear insert plate 12 and located on the left and right sides of the cantilever support pipe 2, respectively. The cantilever support pipe 2 passes through the front baffle 11 and the rear insert plate 12 and is connected to the front baffle 11 and the rear insert plate 12 by welding. The plate 12 has two slots 121 for inserting the forklift's forks 51, so that the two forklift's forks 51 can support the corresponding load-bearing beam 13. The front baffle 11 is used to block the forklift's forks 51 from moving forward. The cantilever support pipe 2 is fixed with a buckle 14 located between the front baffle 11 and the rear insert plate 12. The buckle 14 is connected to a chain 15. The other end of the chain 15 away from the buckle 14 is provided with a lock buckle 16. The lock buckle 16 is used to hook the lifting frame 52 on the forklift. The lock buckle can be a D-shaped lock hook. The D-shaped lock buckle is provided with a detachable pin. By removing the pin, the lock buckle can be fastened to the crossbeam of the lifting frame.
[0029] When the molten aluminum furnace iron collection device is in operation, the movement and working position adjustment of the equipment are first achieved through the cooperation of the forklift's forks 51 and the insert frame 1. Specifically, the two forklift forks 51 are inserted into the two slots 121 on the rear insert plate 12 of the insert frame 1. At this time, the forklift forks 51 support the load-bearing beams 13 located on the left and right sides of the cantilever support pipe 2, while the front baffle 11 acts as a blocking force to prevent the forklift forks 51 from moving forward relative to the insert frame 1. At the same time, the operator hooks the buckle 16 on the chain 15 onto the lifting frame 52 on the forklift, and the tension of the chain 15 further fixes the relative position of the insert frame 1 and the forklift forks 51, preventing the forklift forks 51 from moving backward relative to the insert frame 1.
[0030] After connecting and fixing the fork arm 51 to the insert frame 1, the entire device is moved to the side of the aluminum molten furnace using the movement and lifting operation of a forklift. By adjusting the position of the forklift, the permanent magnet head 3 at the end of the cantilever branch pipe 2 away from the insert frame 1 is inserted into the molten aluminum in the furnace. Because the permanent magnet head 3 has strong magnetism, it can attract ferromagnetic impurities in the molten aluminum. During operation, the position and depth of the permanent magnet head 3 in the molten aluminum are adjusted using the forklift to ensure comprehensive collection of ferromagnetic impurities. After a certain amount of ferromagnetic impurities have been attracted, the permanent magnet head 3 is removed from the furnace using the forklift, completing the collection of ferromagnetic impurities.
[0031] The aluminum molten furnace magnetic iron collection device provided by this utility model uses a permanent magnet magnetic head 3 to replace the traditional electromagnet, eliminating the need for long-distance power supply connection and avoiding the problem of the forklift pulling the cable during movement, which affects the power connection. It also prevents the insulation layer of the cable near the furnace from aging due to high temperature, greatly extending the service life of the equipment and reducing the risk of failure caused by cable problems.
[0032] In addition, the insert frame 1 blocks the fork arm 51 from moving forward through the front baffle 11. Combined with the cooperation of the chain 15 and the latch 16, the insert frame 1 is connected to the lifting frame 52 of the forklift, which effectively prevents the fork arm 51 from moving backward relative to the insert frame 1. This forms a reliable mechanical limiting and fixing structure, which solves the problem caused by the relative movement of the insert frame 1 and the fork arm 51.
[0033] For details, see Figures 3 to 5 As shown, the permanent magnet attractor 3 includes a cylindrical shell 31, a permanent magnet 32 disposed inside the shell 31, and a bent tube 33 disposed on the top of the shell 31. The bent tube 33 is welded to the cantilever branch pipe 2. The cylindrical shell 31 is designed to make it more smoothly contact the molten aluminum when it extends into the furnace, which can reduce interference with the flow of molten aluminum. At the same time, the cylindrical structure makes it easy to flexibly adjust its position in the molten aluminum, and can more conveniently go into different areas of the furnace to perform magnet attracting operations. Especially when dealing with the complex molten aluminum environment in the furnace, it can reduce the probability of scraping against the inner wall of the furnace and improve the safety of the operation.
[0034] The bottom surface of the permanent magnet attracting head 3 is an attracting surface, which can form a concentrated and stable magnetic field area, enhancing the ability to adsorb ferromagnetic impurities.
[0035] The permanent magnet 32 is preferably made of high-temperature resistant, high-strength permanent magnets, such as samarium cobalt permanent magnets, which can maintain stable magnetic force in high-temperature environments and avoid magnetic force attenuation due to excessive temperature. Although the selected samarium cobalt permanent magnets and other high-temperature resistant, high-strength permanent magnets themselves have a certain high-temperature tolerance, the continuous high-temperature impact in the extreme high-temperature environment of the aluminum molten furnace may still affect their magnetic stability. To this end, a heat insulation layer 34 is provided between the permanent magnet 32 and the inner wall of the shell 31. The heat insulation layer 34 reduces the heat transferred to the permanent magnet 32, which can reduce the interference of high temperature on the internal magnetic domain structure of the permanent magnet 32, avoid the problem of magnetic force attenuation due to excessive temperature, and ensure that the permanent magnet 32 maintains a stable and strong magnetic force during long-term operation, thus ensuring the adsorption effect on ferromagnetic impurities.
[0036] For details, see Figure 3 As shown, the load-bearing beam 13 includes a bottom flat beam 131 and an upright beam 132 forming an L-shaped structure. The side of the bottom flat beam 131 is welded to the cantilever support pipe 2 through reinforcing ribs 17. The L-shaped bottom flat beam 131 and the upright beam 132 cooperate with each other to form a stable load-bearing frame. The bottom flat beam 131 mainly bears the vertical load transmitted by the forklift fork arm 51, while the upright beam 132 can enhance the load-bearing beam 13's resistance to deformation in both the lateral and vertical directions. The combination of the two significantly improves the overall rigidity of the load-bearing beam 13, effectively resisting various external forces generated during operation due to equipment movement, magnetic adsorption of impurities, etc., reducing bending, twisting and other deformations of the load-bearing beam 13, and ensuring the structural stability of the insert frame 1.
[0037] When the forklift arm 51 lifts the load-bearing beam 13, the contact area between the bottom flat beam 131 and the forklift arm 51 is large, which can evenly transfer the load to the entire load-bearing beam 13, avoiding structural damage caused by excessive local stress. This allows the load-bearing beam 13 to stably support the weight of components such as the cantilever support pipe 2, the permanent magnet head 3, and the adsorbed ferromagnetic impurities, meeting the load-bearing requirements of long-term high-intensity operation.
[0038] Specifically, the iron removal and collection mechanism 4 includes a support platform 41 for supporting the cantilever branch pipe 2, a U-shaped platform 42 disposed in front of the support platform 41, a scraper 43 and an air blowing rod 44 slidably disposed on the top of the U-shaped platform 42, and an iron material collection tray 45 disposed inside the U-shaped platform 42; the scraper 43 is used to scrape off the iron material on the bottom surface of the permanent magnet attracting head 3, and the air blowing rod 44 is used to blow compressed air to clean the bottom surface of the permanent magnet attracting head 3.
[0039] After the magnet is in operation, the cantilever support pipe 2 is placed on the support platform 41 by a forklift. At this time, the permanent magnet magnet head 3 is moved above the U-shaped platform 42. Since the magnet structure consisting of the entire insertion frame 1, cantilever support pipe 2 and permanent magnet magnet head 3 is heavy, the permanent magnet magnet head 3 will stand upright and not deflect after being placed.
[0040] At this time, the scraper 43, which is slidably mounted on the top of the U-shaped platform 42, begins to work. The scraper 43 moves towards the bottom surface of the permanent magnet head 3 and contacts the bottom surface of the permanent magnet head 3, scraping off most of the iron material adsorbed on the bottom surface by sliding and scraping. After the scraper 43 scrapes off the iron material, the air blowing rod 44 then operates, blowing compressed air towards the bottom surface of the permanent magnet head 3. The impact force of the compressed air is used to further clean the bottom surface, blowing off any small iron materials or residual iron filings that the scraper 43 failed to scrape off.
[0041] The scraped and blown iron will fall into the iron collection tray 45 set in the U-shaped platform 42, where the iron collection tray 45 will collect the iron in a concentrated manner, thus completing the entire iron removal and collection process.
[0042] The scraper 43 and the air blower 44 work together to form a dual cleaning mechanism. The scraper 43 can effectively scrape off larger pieces or strongly adhered iron materials on the bottom surface of the permanent magnet head 3, while the air blower 44 can clean away fine iron filings and residual iron materials with compressed air. The combination of the two greatly improves the cleanliness of the bottom surface of the permanent magnet head 3 and avoids iron material residue from affecting the effect of subsequent adsorption operations.
[0043] Furthermore, the two outer sides of the U-shaped platform 42 are provided with channel steel 40 extending forward and backward. The two channel steel 40 are provided with a movable first roller frame 46 and a second roller frame 47. Both the first roller frame 46 and the second roller frame 47 are provided with push handles 49. The scraper 43 is provided on the first roller frame 46, and the air blowing rod 44 is provided with the second roller frame 47. During cleaning operations, workers can easily control the scraper 43 and the air blower 44 to move closer to or away from the permanent magnet head 3 by pushing the handle 49. The channel steel 40 provides a stable moving track for the first roller frame 46 and the second roller frame 47. With the cooperation of the roller 482 and the channel steel 40, the two roller frames 482 can move smoothly in the front and back direction, thereby driving the scraper 43 and the air blower 44 to flexibly adjust their positions. The cleaning position and range can be precisely adjusted according to the adhesion of the iron material on the bottom surface of the permanent magnet head 3. This ensures that the scraper 43 can fully contact the bottom surface of the magnet head to complete the scraping, and that the air blower 44 can be aimed at the target area to blow air efficiently, improving the targeting and flexibility of the cleaning operation.
[0044] The push handle 49 allows operators to control the scraper 43 and air blower 44 from a safe distance without close contact with the high-temperature permanent magnet head 3, reducing the impact of the high-temperature environment on operators. To prevent burns from flying slag, a transparent baffle can be installed on the side of the U-shaped table 42 near the push handle 49, with clearance grooves to allow the push handle 49 to move.
[0045] Both the first roller frame 46 and the second roller frame 47 include an L-shaped plate 481, two foot plates 484 located at the bottom of both ends of the L-shaped plate, and several rollers 482 located inside the two foot plates 484. The multiple rollers 482 simultaneously contact the channel steel 40, distributing the force on the roller 482 frame and making it more stable and reducing swaying when moving on the channel steel 40. Two vertically extending oblong holes 483 are provided on the vertical plate of the L-shaped plate 481. These two oblong holes 483 provide vertical adjustment space for the installation of the scraper 43 or the air blower 44. Workers can adjust the installation height of the scraper 43 or the air blower 44 through the oblong holes 483 according to the height of the bottom surface of the permanent magnet head 3, ensuring optimal contact or blowing distance with the bottom surface of the permanent magnet head 3. For example, when the scraper 43 wears down and its height decreases, the position of the scraper 43 can be adjusted upward through the oblong hole 483 to ensure that it can still effectively scrape off the iron material; for the air blower 44, the height can also be adjusted to ensure that the compressed air can be accurately blown to the bottom of the iron suction head, thereby improving the cleaning effect.
[0046] Correspondingly, the scraper 43 has the same number of first threaded holes as the oblong holes 483 on the first roller frame 46, and each hole has a first screw passing through it. The first screw is connected to the corresponding first threaded hole. When the height of the scraper 43 needs to be adjusted, simply loosen the first screw, and the scraper 43 can be moved vertically along the oblong holes 483. After adjusting to the appropriate height, tighten the first screw to complete the fixation. The entire adjustment process is simple to operate, requiring no complicated disassembly steps. It can quickly adapt to changes in the height of the bottom surface of the permanent magnet head 3 or the height compensation requirements after the scraper 43 wears, ensuring that the scraper 43 always maintains the best contact state with the bottom surface of the permanent magnet head 3, thus improving the scraping effect.
[0047] Correspondingly, the air-blowing rod 44 is provided with multiple upward-facing air nozzles. The blowing angle of the air nozzles can be finely adjusted to form multi-point, multi-angle airflow coverage. Both ends of the air-blowing rod 44 are provided with lugs 442. Each lug 442 has a second threaded hole corresponding to the oblong hole 483 on the second roller frame 47. A second screw passes through each oblong hole 483, and the second screw connects to the corresponding second threaded hole. For fixing and adjustment, the cooperation between the second screw and the second threaded hole securely fixes the air-blowing rod 44 to the second roller frame 47, preventing it from loosening or shifting due to air pressure reaction force during air blowing operations. Taking advantage of the vertical extension characteristic of the oblong hole 483, loosening the second screw 444 allows for vertical adjustment of the height of the air-blowing rod 44, precisely adapting to the height changes of the bottom surface of the permanent magnet head 3. This ensures that the multiple upward-facing air nozzles are directly facing the bottom surface of the magnet head, allowing compressed air to directly act on the iron filings residue area, improving cleaning efficiency. After adjustment, tighten the screws to quickly lock the position, making the operation convenient and the fixation reliable.
[0048] Preferably, the top of the support platform 41 is provided with an arc-shaped groove 411 that matches the diameter of the cantilever branch pipe 2, and the inner wall of the arc-shaped groove 411 is covered with an anti-slip layer. Regarding stability when idle, the arc-shaped groove 411 can fit tightly against the outer surface of the cantilever branch pipe 2, providing a stable support structure for the cantilever branch pipe 2 in its idle state. Since the cantilever branch pipe 2 is relatively long, it is prone to swaying if the support is unstable when idle. The arc-shaped groove 411, through its design to match the pipe diameter, can limit the horizontal displacement of the cantilever branch pipe 2, preventing swaying, displacement, or even tipping of the cantilever branch pipe 2 due to minor external impacts or ground vibrations, thus ensuring the safety of the equipment when idle.
[0049] When performing iron removal and collection operations, the anti-slip layer plays a crucial role when the cantilever branch pipe 2 is placed on the support platform 41. During the iron removal and collection process, the scraper 43 scrapes against the permanent magnet attracting head 3 or the air blower 44 sprays air, generating a reaction force that may cause the cantilever branch pipe 2 to slide on the support platform 41. The anti-slip layer effectively counteracts these reaction forces by increasing the friction between itself and the cantilever branch pipe 2, preventing relative sliding of the cantilever branch pipe 2. This ensures the stability of the cantilever branch pipe 2 during iron removal and collection operations, providing a reliable foundation for the precise operation of the scraper 43 and the air blower 44, and guaranteeing the smooth progress of iron removal.
