Description

Technical Field

[0001] This invention relates to the field of amorphous magnetic core production technology, specifically to a device for surface insulation treatment of amorphous magnetic core casings for transformers. Background Technology

[0002] Amorphous magnetic cores for transformers are made of amorphous alloys and possess excellent electromagnetic properties such as high permeability and low iron loss. They are core components of energy-saving transformers. However, amorphous alloys are brittle and susceptible to stress damage during processing and use. The core casing provides mechanical protection for the amorphous magnetic core, preventing cracks, brittle fractures, or lamination separation during winding, handling, and cutting processes, thus ensuring the structural integrity and performance stability of the core. Surface insulation treatment of the casing is a crucial step. It not only blocks eddy current paths to reduce additional transformer losses but also prevents electrical short circuits between the casing and surrounding components. Furthermore, it enhances the casing's corrosion resistance and extends the overall service life of the magnetic core. Therefore, the efficiency and reliability of casing insulation treatment are critical requirements.

[0003] However, existing spraying processes have obvious drawbacks: First, dead corners are easily formed at the edges and seams of the protective shell, resulting in discontinuous insulation layers and the risk of leakage. Second, mechanical spraying makes it difficult to precisely control the spraying angle, and the coating thickness is prone to being too thick or too thin in some areas, affecting the heat dissipation performance and insulation reliability of the magnetic core. In addition, the insulating coating is lost due to atomization and splashing during the spraying process and cannot be recycled, which increases production costs and creates a cleaning burden. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide a surface insulation treatment device for amorphous magnetic core shells for transformers, so as to at least partially solve the problems mentioned in the background art.

[0005] Therefore, the purpose of this invention is to provide a surface insulation treatment device for amorphous magnetic core casing of transformers, which results in a more uniform insulation layer and requires less insulation material.

[0006] To achieve the above objectives, this invention proposes a surface insulation treatment device for amorphous magnetic core casings of transformers, comprising a treatment box, and a feeding mechanism, an impregnation mechanism, and a drying mechanism disposed inside the treatment box. The feeding mechanism includes a conveyor belt arranged laterally inside the treatment box. The impregnation mechanism is disposed on the conveyor belt and includes an impregnation tank and side pressure rollers.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The surface insulation treatment device for amorphous magnetic core casing of transformers according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the surface insulation treatment equipment for amorphous magnetic core shell of transformer provided in this embodiment of the invention includes a treatment box 1, and a feeding mechanism 2, an impregnation mechanism 3 and a drying mechanism 4 disposed inside the treatment box 1. The bottom of the treatment box 1 is provided with a device support 13, and the feeding mechanism 2 includes a transmission mesh belt 22 disposed horizontally inside the treatment box 1.

[0023] The paint dipping mechanism 3 is installed on the conveyor belt 22. The paint dipping mechanism 3 includes a paint dipping tank 31 and a side pressure roller 32. The paint dipping tank 31 is installed inside the processing box 1, and the side pressure roller 32 is installed inside the paint dipping tank 31 to press the conveyor belt 22 against the bottom of the paint dipping tank 31. The drying mechanism 4 is installed at the discharge end of the paint dipping tank 31. The drying mechanism 4 includes a hot dryer 41 installed above the conveyor belt 22.

[0024] Specifically, in use, the transformer amorphous magnetic core shell surface insulation treatment equipment of this application first injects insulating coating into the impregnation tank 31. After the shell is put on, the magnetic core 6 is gradually placed flat on the conveyor belt 22 and gradually fed into the impregnation tank 31 by the conveyor belt 22. After the conveyor belt 22 enters the impregnation tank 31, the side pressure roller 32 presses the conveyor belt 22 into the bottom of the impregnation tank 31, so that the magnetic core 6 is completely submerged in the insulating coating. The surface of the magnetic core 6 can be fully covered with the insulating coating, and the amount of insulating coating material used is small. Then, the conveyor belt 22 continues to carry the magnetic core 6 to the bottom of the dryer, and the dryer gradually dries the magnetic core 6 coated with insulating coating.

[0025] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the feeding mechanism 2 has two parts, one above the other, which are connected to each other by a flip panel assembly 27. The inner ends of the conveyor belt 22 are provided with guide rollers 25, feeding drive rollers 24 and discharging drive rollers 26.

[0026] The flip panel assembly 27 includes an arc-shaped guide plate 272 and an inclined guide plate 271. The arc-shaped guide plate 272 is disposed at the discharge end of the upper conveyor belt 22, and the inclined guide plate 271 is disposed at the feed end of the lower conveyor belt 22. The bottom of the arc-shaped guide plate 272 is smoothly connected to the top of the inclined guide plate 271.

[0027] Specifically, during the surface insulation treatment of the magnetic core 6, the sidewalls and upper end face of the magnetic core 6 are fully impregnated with varnish, but the bottom end face of the magnetic core 6 cannot be fully impregnated with varnish because it is in contact with the transmission belt 22.

[0028] To ensure that the bottom surface of the magnetic core 6 is also fully impregnated with paint, the upper conveyor belt 22 drives the magnetic core 6 to move continuously to the left through the feeding drive roller 24 and the discharging drive roller 26. After the magnetic core 6 is impregnated by the upper conveyor belt 22 and then dried and cured, when the magnetic core 6 moves to the position of the flip panel assembly 27, the magnetic core 6 first enters the arc-shaped guide plate 272. The magnetic core 6 is clamped by the arc-shaped guide plate 272 and the conveyor belt 22 and enters the inclined guide plate 271. After passing through the inclined guide plate 271, it enters the lower conveyor belt 22. At this time, the upper and lower end faces of the magnetic core 6 are flipped 180°. The side of the magnetic core 6 that is not fully impregnated with paint is impregnated again through the impregnation tank 31. Then it is dried and cured a second time through the lower drying mechanism 4. Finally, both end faces and side walls of the magnetic core 6 are fully impregnated with paint to prevent dead corners due to inadequate insulation.

[0029] In one embodiment of the present invention, such as Figure 3As shown, the axis of the arc-shaped guide plate 272 coincides with the axis of the discharge drive roller 26. The inner wall of the arc-shaped guide plate 272 is provided with guide rollers 273, so that the magnetic core 6 can pass smoothly through the arc-shaped guide plate 272 and reduce the movement resistance of the magnetic core 6 inside the arc-shaped guide plate 272.

[0030] In one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the upper surface of the transmission belt 22 is provided with a protruding positioning buckle 21, which is used to position the bottom of the inner ring of the magnetic core 6.

[0031] Specifically, during the transmission of the magnetic core 6, in order to ensure that the magnetic core 6 is evenly distributed on the transmission belt 22, the inner ring of the magnetic core 6 is fixed by the positioning buckle 21, which makes the magnetic core 6 more evenly distributed on the transmission belt 22 and can also prevent the magnetic core 6 from sliding or shifting during transmission. In addition, the positioning buckle 21 can also make the magnetic core 6 move effectively when entering the arc-shaped guide plate 272, preventing the magnetic core 6 from spinning freely inside the arc-shaped guide plate 272 and preventing transmission blockage.

[0032] In one embodiment of the present invention, such as Figure 3 and Figure 6 As shown, the surface of the conveyor belt 22 is a hollow mesh structure. An ultrasonic vibrator 33 is provided below the side pressure roller 32. The two ends of the paint immersion tank 31 are provided with conveyor belt inlet and outlet 311. The discharge end of the paint immersion tank 31 is provided with a paint scraper roller 34. The outer surface of the paint scraper roller 34 is provided with a scraper 341. The paint scraper roller 34 is in contact with the lower surface of the conveyor belt 22, and the paint scraper roller 34 is located directly below the inner side of the paint immersion tank 31.

[0033] Specifically, after the conveyor belt 22 enters the impregnation tank 31, the perforated conveyor belt 22 allows the insulating coating to pass through smoothly and quickly impregnates the magnetic core 6 on the conveyor belt 22. After entering the impregnation tank 31, the conveyor belt 22 is pressed down to the bottom of the impregnation tank 31 by the side pressure roller 32 to prevent the top of the magnetic core 6 from being exposed, so that the magnetic core 6 is completely immersed in the liquid insulating coating. After the conveyor belt 22 enters the bottom of the impregnation tank 31, the ultrasonic vibrator 33 causes the surface of the conveyor belt 22 and the magnetic core 6 to vibrate at high frequency, so that the insulating coating can fully fuse with the surface of the magnetic core 6 and reduce the generation of air bubbles.

[0034] Subsequently, the conveyor belt 22 continues to move upward at an angle after passing through the side pressure roller 32. The magnetic core 6 and the insulating coating on the conveyor belt 22 seep down to the bottom of the conveyor belt 22 under the action of gravity. The excess insulating coating at the bottom of the conveyor belt 22 is scraped downward by the rotating paint scraper roller 34 and falls back into the paint soaking tank 31, reducing the waste of insulating coating.

[0035] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, a conveyor belt cleaning mechanism 5 is provided below the discharge drive roller 26. The conveyor belt cleaning mechanism 5 includes two cleaning brush rollers 54, which are located on the upper and lower sides of the conveyor belt 22 respectively. A spray plate 53 is provided at the inlet end of the cleaning brush roller 54, and a drying fan 55 is provided at the outlet end of the cleaning brush. Two spray plates 53 and two drying fans 55 are provided, which are located on the upper and lower sides of the conveyor belt 22 respectively.

[0036] A stain tray 52 is provided below the cleaning brush roller 54. The stain tray 52 has a bucket-shaped structure. A shovel 521 is provided at one end of the stain tray 52 near the discharge drive roller 26 so that the magnetic core 6 on the conveyor belt 22 can be separated from the conveyor belt 22 smoothly. A drain port 51 is provided at the bottom of the stain tray 52 for discharging the wastewater after cleaning.

[0037] Specifically, after the magnetic core 6 is dried and cured, the conveyor belt 22 carries the magnetic core 6 away from the conveyor belt 22 via the material shovel 521. Since the conveyor belt 22 has excess insulating coating attached, it needs to be removed in time. The conveyor belt 22 continues to move into the spray plate 53. The spray plate 53 sprays loosening agent and cleaning agent on both sides of the conveyor belt 22 respectively. Then, the upper and lower sides of the conveyor belt 22 are cleaned by two cleaning brush rollers 54 to remove the coating attached to the surface of the conveyor belt 22. The coating and cleaning agent are mixed together and fall into the stain tray 52 for collection and are discharged through the drain port 51, so that the surface of the conveyor belt 22 is restored to cleanliness when it is used for the next round.

[0038] In one embodiment of the present invention, such as Figure 3 As shown, there are two drying fans 55, which are located above the two conveyor belts 22 respectively. A drying panel 42 is provided at the bottom of the drying fan 55. The air outlet of the drying fan 55 is connected to the drying panel 42. An air outlet is provided at the bottom of the drying panel 42.

[0039] Specifically, after being impregnated with varnish, the magnetic core 6 enters below the drying fan 55. The drying fan 55 transmits hot air to the drying panel 42, and the hot air is evenly projected downward onto the surface of the magnetic core 6 through the drying panel 42. The mesh structure of the transmission belt 22 allows the hot air to pass smoothly downward, improving the drying speed of the magnetic core 6.

[0040] In one embodiment of the present invention, such as Figure 3 As shown, the processing box 1 is provided with a feed inlet 23 and a discharge outlet 28. The feed inlet 23 is located at the feed end of the upper conveyor belt 22, and the discharge outlet 28 is located at the discharge end of the lower conveyor belt 22. The bottom of the discharge outlet 28 is provided with an inclined finished product guide plate 14, which is used to smoothly guide the magnetic core 6 at the discharge outlet 28 along the finished product guide plate 14.

[0041] The top of the treatment box 1 is provided with a top maintenance port 11, and the sides of the treatment box 1 are provided with side wall maintenance ports 12, which facilitates multi-angle maintenance of the treatment box 1.

[0042] To clearly illustrate the above embodiments, refer to Figures 1-6 The specific working principle of the transformer amorphous magnetic core shell surface insulation treatment equipment of the present invention is as follows: When using the transformer amorphous magnetic core shell surface insulation treatment equipment of this application, the magnetic core 6 after being covered with a shell by injecting insulating coating into the impregnation tank 31 is gradually placed flat on the transmission mesh belt 22. The inner ring of the magnetic core 6 is fixed by the positioning buckle 21, so that the magnetic core 6 is effectively positioned and evenly distributed on the transmission mesh belt 22.

[0043] Following this, impregnation occurs. The upper conveyor belt 22, driven by the feed drive roller 24 and the discharge drive roller 26, continuously moves the magnetic core 6 to the left. After entering the impregnation tank 31, the perforated conveyor belt 22 allows the insulating coating to pass through smoothly and quickly impregnates the magnetic core 6. After entering the impregnation tank 31, the conveyor belt 22 is pressed down to the bottom of the tank by the side pressure roller 32, ensuring the magnetic core 6 is completely immersed in the liquid insulating coating. After entering the bottom of the impregnation tank 31, the ultrasonic vibrator 33 causes high-frequency vibration of the conveyor belt 22 and the surface of the magnetic core 6, allowing the insulating coating to fully fuse with the surface of the magnetic core 6. The surface of the magnetic core 6 is completely covered with the insulating coating, requiring less insulating coating material.

[0044] Subsequently, the conveyor belt 22 continues to move upward at an angle after passing through the side pressure roller 32. The magnetic core 6 and the insulating coating on the conveyor belt 22 seep down to the bottom of the conveyor belt 22 under the action of gravity. The excess insulating coating at the bottom of the conveyor belt 22 is scraped downward by the rotating paint scraper roller 34 and falls back into the paint soaking tank 31, reducing the waste of insulating coating.

[0045] After the magnetic core 6 is impregnated with paint by the upper conveyor belt 22, it is fully dried and cured at the bottom of the hot dryer 41. After the magnetic core 6 is dried and cured, the conveyor belt 22 carries the magnetic core 6 away from the conveyor belt 22 via the material shovel 521. The conveyor belt 22 continues to move into the spray plate 53. The spray plate 53 sprays loosening agent and cleaning agent on both sides of the conveyor belt 22 respectively. Then, two cleaning brush rollers 54 clean the upper and lower sides of the conveyor belt 22 to remove impurities from the surface of the conveyor belt 22.

[0046] Subsequently, when the magnetic core 6 moves to the position of the flip panel assembly 27, the magnetic core 6 first enters the arc-shaped guide plate 272. Clamped by the arc-shaped guide plate 272 and the transmission belt 22, the magnetic core 6 enters the inclined guide plate 271 and then passes through the inclined guide plate 271 onto the lower transmission belt 22. At this point, the upper and lower end faces of the magnetic core 6 are flipped 180°. The side of the magnetic core 6 that is not fully impregnated with paint is then impregnated again in the impregnation tank 31. It then undergoes a second drying and curing process through the lower drying mechanism 4. Finally, both end faces and side walls of the magnetic core 6 are fully impregnated with paint, preventing dead zones due to inadequate insulation.

[0047] In summary, the transformer amorphous magnetic core casing surface insulation treatment equipment of this invention, by setting up an impregnation tank inside the treatment box, injecting insulating coating into the impregnation tank, and gradually feeding the magnetic core into the impregnation tank by a conveyor belt, and pressing the conveyor belt into the bottom of the impregnation tank by side pressure rollers, so that the magnetic core is completely submerged in insulating coating, the surface of the magnetic core can be fully covered with insulating coating, and the amount of insulating coating material used is small. Subsequently, the magnetic core coated with insulating coating is gradually dried from the bottom of a dryer by the conveyor belt, resulting in a more uniform insulation layer.

[0048] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
