Description

Technical Field

[0001] This invention relates to the field of copper alloy descaling technology, specifically to a laser cladding metal surface oxide scale treatment device. Background Technology

[0002] In today's industrial sector, copper and copper alloys are widely used in machinery manufacturing, power electronics, metallurgy, marine equipment, and many other fields due to their excellent electrical and thermal conductivity and machinability. However, with industrial development, the traditional properties of copper are no longer sufficient for demanding applications. Especially in specialized fields, harsh environments place higher demands on the performance of copper parts. For example, electromagnetic rails requiring high strength and high conductivity, continuous casting crystallizers requiring high wear resistance and heat resistance, and copper rolls in aluminum plate rolling production lines all require copper surfaces to withstand continuous high temperatures, high pressures, or severe wear during production, resulting in harsh working environments. Methods to improve the surface properties of copper alloys include electroplating, melt infiltration, and spraying. However, these methods have certain drawbacks. The plating layers cause serious environmental pollution, melt infiltration is prone to porosity defects, and spraying interfaces are difficult to achieve metallurgical bonding, requiring repeated thermal spraying.

[0003] Laser cladding technology for copper alloys is an important means of surface modification. It has the advantages of high flexibility, low thermal impact on the workpiece, and high bonding strength between the coating and the substrate. This technology can be used to obtain coatings with dense structure and excellent performance.

[0004] Copper oxide scale cleaner is an environmentally friendly industrial cleaning agent with strong penetrating power. It can easily and quickly remove rust, high-temperature black scale, and oxide scale from the surface of copper parts. Generally, the copper oxide scale cleaner solution is prepared according to a certain ratio according to the needs. Then, the copper workpiece is placed in it and soaked for several minutes to remove the oxide scale. However, this method can only be used for a small number of copper workpieces. For a large number of small copper workpieces, such as copper sheets, removing oxide scale individually using this method would be labor-intensive and inefficient. If a large number of copper sheets are directly poured in for batch washing, the copper sheets will accumulate and cannot fully contact the cleaning agent, resulting in incomplete oxide scale removal. Moreover, the accumulated copper sheets will have low dehydration and drying efficiency after washing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a laser cladding metal surface oxide scale removal device, which solves the following problems: In existing technologies, the removal of copper alloy oxide scale typically involves first preparing a copper oxide scale cleaning agent solution according to a certain ratio based on requirements, then immersing the copper workpiece in the solution for several minutes to remove the oxide scale. However, this method can only be used for a small number of copper workpieces. For a large number of relatively small copper workpieces, such as copper sheets, removing oxide scale individually using this method results in a large workload for the operator and low efficiency. If a large number of copper sheets are directly poured in for batch washing, the copper sheets will accumulate and cannot fully contact the cleaning agent, leading to incomplete oxide scale removal. Furthermore, the accumulated copper sheets have low dehydration and drying efficiency after washing.

A cleaning door is located above the filter screen and is opened on the filter barrel. An outlet pipe is located below the filter screen and is fixedly connected to the bottom of the filter barrel. The other end of the outlet pipe is fixedly connected to the outer wall of the outer barrel.

[0013] Preferably, the unidirectional flow guiding structure includes a blocking block, which is fixedly connected to the inner wall of the inlet pipe.

[0017] The beneficial effects of this invention are:

[0018] 1. In the laser cladding metal surface oxide scale treatment device of the present invention, after the inner tub is positioned, the vertical rod is in the inner tub. At this time, the copper alloy sheet begins to react with the washing water, and the copper rust on the surface of the copper alloy sheet begins to fall off. Then, the dual-axis motor is started. The upper shaft of the dual-axis motor drives the turbine to rotate. The rotation of the turbine will drive the copper alloy sheet and the washing water in the inner tub to rotate. At this time, the copper alloy sheet will be flipped over. At the same time, the copper alloy sheet squeezed at the bottom can also come into contact with the washing water, and the reaction is faster and more complete. When the copper alloy sheet and the washing water rotate together in the inner tub, they will collide with the vertical rod. The vibration generated by the collision will accelerate the removal of copper rust from the surface of the copper alloy sheet.

[0019] 2. In the laser cladding metal surface oxide scale treatment device of the present invention, the turbine rotates at high speed in the cleaning mechanism, and the centrifugal force generated in the inner barrel will throw the detached copper rust onto the inner wall of the inner barrel. The copper rust will leave the inner barrel through the leakage hole and enter the outer barrel.

[0020] 3. In the laser cladding metal surface oxide scale treatment device of the present invention, after the inner barrel slides upward in the outer barrel, the upper end of the inner barrel abuts against the lower end of the air hood, forming a closed space. When the inner barrel and the air hood are in contact, the upper end of the inner barrel will squeeze the telescopic rod, and the telescopic rod will compress the pressure spring. At the same time, the telescopic rod extends upward through the limit plate and contacts the switch. After the switch is turned on, the third motor starts and drives the first fan blade to rotate. The first fan blade begins to blow air onto the copper alloy sheet in the inner barrel. At the same time, the upper shaft of the dual-shaft motor drives the turbine to rotate slowly, which can turn the copper alloy sheet in the inner barrel over and accelerate the evaporation of moisture on the surface of the copper alloy sheet. After the copper alloy sheet is completely dry, the user can open the inner door to collect it.

[0021] 4. In the laser cladding metal surface oxide scale treatment device of the present invention, after the inner barrel rises, it drives the rotating rod and the second fan blade to rise. The lower shaft of the dual-axis motor drives the rotating rod to rotate slowly, and the rotating rod drives the second fan blade to rotate slowly. The slow rotation of the second fan blade will drive the washing water at the bottom of the outer barrel to rotate. The rotation of the washing water forms a vortex, and the copper shavings in the water will gradually concentrate in the middle of the outer barrel, that is, above the drain port. When the water pump is working, it will generate suction in the inlet pipe. The washing water and copper rust near the drain port will be continuously sucked into the filter barrel for filtration during the working time of the water pump. Attached Figure Description

[0034] The technical solution in this embodiment of the invention is to solve the above-mentioned technical problems. The general idea is as follows: The user pours the copper alloy sheet into the inner tub 13, and then the inner tub 13 slides into the interior of the outer tub 11. The vertical rod 18 and the inner tub 13 slide relative to each other. After the inner tub 13 is in place, the vertical rod 18 is in the inner tub 13. At this time, the copper alloy sheet begins to react with the washing water, and the copper rust on the surface of the copper alloy sheet begins to fall off. Then, the dual-shaft motor 16 is started. The upper shaft of the dual-shaft motor 16 drives the turbine 15 to rotate. The rotation of the turbine 15 will drive the copper alloy sheet and the washing water in the inner tub 13 to rotate. At this time, the copper alloy sheet will be flipped over, and the copper alloy sheet squeezed at the bottom can also come into contact with the washing water, making the reaction faster and more complete. When the copper alloy sheet and the washing water rotate together in the inner tub 13, they will collide with the vertical rod 18. The vibration generated by the collision will increase The copper rust on the surface of the copper alloy sheet falls off. At the same time, due to the high-speed rotation of the turbine 15, the centrifugal force generated in the inner tub 13 will throw the fallen copper rust onto the inner wall of the inner tub 13. The copper rust will leave the inner tub 13 through the drain hole 14 and enter the outer tub 11. After washing, the inner tub slides upward in the outer tub, and the upper end of the inner tub will abut against the lower end of the fan hood, forming a closed space. When the inner tub and the fan hood are in contact, the upper end of the inner tub will squeeze the telescopic rod, and the telescopic rod will compress the pressure spring. At the same time, the telescopic rod extends upward through the limit plate and contacts the switch. After the switch is turned on, the third motor starts. The third motor drives the first fan blade to rotate. The first fan blade begins to blow air onto the copper alloy sheet in the inner tub. At the same time, the upper shaft of the dual-shaft motor drives the turbine to rotate slowly, which can turn the copper alloy sheet in the inner tub over and accelerate the evaporation of moisture on the surface of the copper alloy sheet.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] like Figures 1-10 As shown, the laser cladding metal surface oxide scale treatment device of the present invention includes a cleaning mechanism 1, a lifting mechanism 2, a filtering mechanism 3, a drying mechanism 4, and a slag removal mechanism 5. The inner barrel 13 and the outer barrel 11 in the cleaning mechanism 1 are slidably connected through the lifting mechanism 2. The filtering mechanism 3 is fixedly connected to one side of the outer barrel 11. The drying mechanism 4 is located above the cleaning mechanism 1. The slag removal mechanism 5 is fixedly connected to the lower end of the inner barrel 13. The cleaning mechanism 1 can remove copper rust from the surface of the copper alloy sheet. The lifting mechanism 2 can lift the inner barrel 13 away from the washing water. The filtering mechanism 3 can filter out the copper rust in the washing water. The drying mechanism 4 can dry the moisture on the surface of the copper alloy sheet, which is beneficial for later preservation. The slag removal mechanism 5 can make the copper rust in the washing liquid accumulate and be more easily filtered.

[0037] Specifically, the cleaning mechanism 1 includes an outer tub 11 with an outer door 12. An inner tub 13 is located inside the outer tub 11, and the inner tub 13 and outer tub 11 are slidably connected. A turbine 15 is rotatably connected to the bottom of the inner tub 13, and the turbine 15 is fixedly connected to the upper shaft of a dual-axis motor 16. The dual-axis motor 16 is fixedly connected to the lower end of the inner tub 13, and its upper shaft passes through the bottom of the inner tub 13 and is rotatably connected to it. An inner door 17 is provided on the inner tub 13. A drain outlet 19 is located at the bottom of the outer tub 11. A leakage hole 14 is provided on the wall of the inner tub 13. A vertical rod 18 is slidably connected to the bottom of the inner tub 13 and is fixedly connected to the bottom of the outer tub 11. First, the user pours copper alloy sheets into the inner tub 13, and then... The inner tub 13 slides into the outer tub 11, and the vertical rod 18 slides relative to the inner tub 13. After the inner tub 13 is in place, the vertical rod 18 is in the inner tub 13. At this time, the copper alloy sheet begins to react with the washing water, and the copper rust on the surface of the copper alloy sheet begins to fall off. Then, the dual-shaft motor 16 is started. The upper shaft of the dual-shaft motor 16 drives the turbine 15 to rotate. The rotation of the turbine 15 will cause the copper alloy sheet and the washing water in the inner tub 13 to rotate. At this time, the copper alloy sheet will be flipped over, and the copper alloy sheet squeezed at the bottom can also come into contact with the washing water, making the reaction faster and more complete. When the copper alloy sheet and the washing water rotate together in the inner tub 13, they will collide with the vertical rod 18. The vibration generated by the collision will accelerate the fall off of the copper rust on the surface of the copper alloy sheet. Due to the high speed of the turbine 15, the centrifugal force generated in the inner tub 13 will throw the fallen copper rust onto the inner wall of the inner tub 13. The copper rust will leave the inner tub 13 through the drain hole 14 and enter the outer tub 11.

[0038] Specifically, the lifting mechanism 2 includes a second motor 21, which is fixedly connected to a carrier frame 22. The carrier frame 22 is fixedly connected to the outer wall of the outer tub 11. The output shaft of the second motor 21 extends into the interior of the outer tub 11 and is fixedly connected to a gear 23. The gear 23 is fixedly connected to the inner wall of the outer tub 11 by a connecting frame 29. The gear 23 meshes with a rack 24, which is fixedly connected to one side of the outer wall of the inner tub 13. A slider 25 is fixedly connected to the other side of the outer wall of the outer tub 11. The slider 25 is slidably connected to a sliding groove 26, which is fixedly connected to the inner wall of the outer tub 11. The connecting rod 27 is fixedly connected to the lower end of the dual-axis motor 16, and the lower end of the connecting rod 27 is fixedly connected to the blocking cone 28. After the washing is completed, the second motor 21 is started. The output shaft of the second motor 21 drives the gear 23 to rotate. The rotation of the gear 23 drives the rack 24 to move upward. The upward movement of the rack 24 drives the inner tub 13 to slide upward. The slider 25 slides upward in the slide groove 26. At the same time, the inner tub 13 drives the connecting rod 27 to move upward. The upward movement of the connecting rod 27 drives the blocking cone 28 to leave the drain port 19. At this time, the drain port 19 is opened. The inner tub 13 slides upward in the outer tub 11, driving the copper alloy sheet to leave the washing water. At the same time, the rotation of the dual-axis motor 16 slows down.

[0039] Specifically, the filtration mechanism 3 includes a filter barrel 31, which is fixedly connected to one side of the outer barrel 11. An inlet pipe 32 is fixedly connected to the upper end of the filter barrel 31, and the other end of the inlet pipe 32 is fixedly connected to the bottom of the outer barrel 11. A one-way flow guide structure 34 and a water pump 33 are installed on the inlet pipe 32. A filter screen 36 is fixedly connected inside the filter barrel 31. A cleaning door 35 is located above the filter screen 36 and is opened on the filter barrel 31. An outlet pipe 37 is located below the filter screen 36 and is fixedly connected to the bottom of the filter barrel 31. The other end of the outlet pipe 37 is fixedly connected to the outer wall of the outer barrel 11. The one-way flow guide structure 34 includes a blocking block 341, which is fixedly connected to the inner wall of the inlet pipe 32. The blocking block 341 and the rubber ball 342 abut against each other. The rubber ball 342 and the support spring 343 are fixedly connected. The support spring 343 is fixedly connected to the inner wall of the inlet pipe 32. The water pump 33 will work continuously for a period of time. When the water pump 33 is working, it will generate suction in the inlet pipe 32. After the rubber ball 342 in the one-way flow structure 34 is subjected to suction, it compresses the support spring 343. The support spring 343 contracts and drives the rubber ball 342 away from the block block 341. At this time, the inlet pipe 32 is opened. The washing water and copper rust near the drain port 19 are continuously sucked into the filter tank 31 during the working time of the water pump 33. After the washing water and copper rust enter the filter tank 31, they are first separated by the filter screen 36. The copper rust will remain on the filter screen 36. The washing water will pass through the filter screen 36 and enter the bottom of the filter tank 31. Then it will return to the outer tank 11 through the outlet pipe 37. The user can clean the filtered copper rust by opening the cleaning door 35.

[0040] Specifically, the drying mechanism 4 includes a fan hood 41, with fixed brackets 42 fixedly connected to both sides of the fan hood 41. The fan hood 41 is above the inner barrel 13. A third motor 43 is fixedly connected to the fan hood 41. The output shaft of the third motor 43 is fixedly connected to a first fan blade 44. The first fan blade 44 is rotatably connected inside the fan hood 41. A cavity 47 is formed on the wall of the fan hood 41. A telescopic rod 46 is located inside the cavity 47. A pressure spring 48 is nested on the telescopic rod 46. The upper end of the pressure spring 48 is fixedly connected to a limiting plate 49. The limiting plate 49 is fixedly connected to the inner wall of the cavity 47. The telescopic rod 46 passes through the limiting plate 49 and is slidably connected to the limiting plate 49. A switch 410 is located above the limiting plate 49. The switch 410 is fixedly connected to the upper wall of the cavity 47. The switch 410 and the telescopic rod 46 cooperate, and the switch 410 and the third motor 43 are connected by the wire 45. After the inner tub 13 slides upward in the outer tub 11, the upper end of the inner tub 13 will abut against the lower end of the fan cover 41 to form a closed space. When the inner tub 13 and the fan cover 41 are in contact, the upper end of the inner tub 13 will squeeze the telescopic rod 46, and the telescopic rod 46 will compress the pressure spring 48. At the same time, the telescopic rod 46 extends upward through the limiting plate 49 and contacts the switch 410. After the switch 410 is turned on, the third motor 43 starts and drives the first fan blade 44 to rotate. The first fan blade 44 starts to blow air on the copper alloy sheet in the inner tub 13. At the same time, the upper shaft of the dual-shaft motor 16 drives the turbine 15 to rotate slowly, which can turn the copper alloy sheet in the inner tub 13 over and accelerate the evaporation of moisture on the surface of the copper alloy sheet. After the copper alloy sheet is completely dry, the user can open the inner door 17 to collect it.

[0041] Specifically, the slag removal mechanism 5 includes a rotating rod 51, which is fixedly connected to the lower shaft of the dual-axis motor 16, rotatably connected to the connecting rod 27, and rotatably connected to the blocking cone 28. The rotating rod 51 passes through the connecting rod 27 and the blocking cone 28 in sequence and is then fixedly connected to the second fan blade 52, which is above the drain outlet 19. After the inner tub 13 rises, it drives the rotating rod 51 and the second fan blade 52 to rise. The lower shaft of the dual-axis motor 16 drives the rotating rod 51 to rotate slowly, and the rotating rod 51 drives the second fan blade 52 to rotate slowly. The slow rotation of the second fan blade 52 will cause the washing water at the bottom of the outer tub 11 to rotate. The rotation of the washing water forms a vortex, and the copper shavings in the water will gradually concentrate in the middle of the outer tub 11, that is, above the drain outlet 19.

[0042] In use, the user first pours the copper alloy sheet into the inner tub 13. The inner tub 13 then slides into the outer tub 11, with the vertical rod 18 sliding relative to it. After the inner tub 13 is in place, the vertical rod 18 is inside. At this point, the copper alloy sheet begins to react with the washing water, and the copper rust on its surface begins to peel off. Then, the dual-shaft motor 16 is activated. The upper shaft of the dual-shaft motor 16 drives the turbine 15 to rotate. The rotation of the turbine 15 causes the copper alloy sheet and washing water in the inner tub 13 to rotate. At this time, the copper alloy sheet is flipped over, and the copper alloy sheet pressed at the bottom can also come into contact with the washing water, resulting in a faster and more complete reaction. As the copper alloy sheet and washing water rotate together in the inner tub 13, they collide with the vertical rod 18. The vibration generated by the collision accelerates the reaction of the copper alloy sheet surface. As the copper rust detaches, the centrifugal force generated in the inner tub 13 due to the high-speed rotation of the turbine 15 throws the detached copper rust onto the inner wall of the inner tub 13. The copper rust then exits the inner tub 13 through the drain hole 14 and enters the outer tub 11. After washing, the second motor 21 starts, and the output shaft of the second motor 21 drives the gear 23 to rotate. The rotation of the gear 23 drives the rack 24 to move upward, which in turn drives the inner tub 13 to slide upward. The slider 25 slides upward in the slide groove 26, and at the same time, the inner tub 13 drives the connecting rod 27 to move upward. The upward movement of the connecting rod 27 drives the blocking cone 28 to move away from the drain port 19. At this time, the drain port 19 is opened, and the inner tub 13 slides upward in the outer tub 11, causing the copper alloy sheet to leave the washing water. At the same time, the rotation of the dual-shaft motor 16 slows down. The lower shaft of motor 16 drives the rotating rod 51 to rotate slowly. The rotating rod 51 drives the second fan blade 52 to rotate slowly. The slow rotation of the second fan blade 52 causes the washing water at the bottom of the outer tub 11 to rotate. The rotating washing water forms a vortex, and the copper shavings in the water will gradually concentrate in the middle of the outer tub 11, that is, above the drain port 19. The suction pump 33 will work continuously for a period of time. When the suction pump 33 is working, it will generate suction in the inlet pipe 32. After the rubber ball 342 in the one-way flow guide structure 34 is subjected to suction, it compresses the support spring 343. The support spring 343 contracts and drives the rubber ball 342 away from the block 341. At this time, the inlet pipe 32 opens, and the washing water and copper rust near the drain port 19 are continuously sucked into the filter tank 31 during the working time of the suction pump 33. After the copper rust enters the filter tub 31, it is first separated by the filter screen 36. The copper rust remains on the filter screen 36, while the washing water passes through the filter screen 36 to the bottom of the filter tub 31. Then, it returns to the outer tub 11 through the outlet pipe 37. The user can clean the filtered copper rust by opening the cleaning door 35. After the inner tub 13 slides upward in the outer tub 11, the upper end of the inner tub 13 abuts against the lower end of the fan shroud 41, forming a closed space. When the inner tub 13 contacts the fan shroud 41, the upper end of the inner tub 13 presses against the telescopic rod 46, which compresses the pressure spring 48. At the same time, the telescopic rod 46 extends upward through the limit plate 49 and contacts the switch 410. After the switch 410 is turned on, the third motor 43 starts, driving the first fan blade 44 to rotate.The first fan blade 44 begins blowing air onto the copper alloy sheets inside the inner tub 13. Simultaneously, the upper shaft of the dual-shaft motor 16 drives the turbine 15 to slowly rotate, turning the copper alloy sheets inside the inner tub 13 and accelerating the evaporation of moisture from their surface. Once the copper alloy sheets are completely dry, the user can open the inner door 17 to collect them.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
