Description

Technical Field

[0001] This utility model relates to the field of insulating oil treatment technology, and in particular to an oil-immersed transformer oil filtration device. Background Technology

[0002] The insulating oil of oil-immersed transformers is easily contaminated by impurities during use and transportation, which leads to a decline in performance. At this time, an oil filtration device is needed to filter the contaminated insulating oil, remove impurities and contaminants mixed in the insulating oil, and restore and maintain the oil's insulation strength and physical and chemical properties.

[0003] During the filtration process of insulating oil, the oil enters a vacuum degassing tank for heating and degassing. Moisture and gas in the oil are separated, drawn away by a vacuum pump, and discharged, restoring the insulating oil to its original properties and ensuring the safe and stable operation of the transformer. However, during the filtration process, the filter element may be damaged or clogged. In such cases, the system needs to be shut down for maintenance. Since the oil filtration system typically uses multiple sets of bolts to fix the end caps, maintenance operations become more frequent and time-consuming, hindering the improvement of maintenance efficiency and reducing downtime.

[0004] Therefore, this application provides an oil-immersed transformer oil filtration device to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oil-immersed transformer oil filtration device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an oil-immersed transformer oil filtration device, comprising an oil filtration device body, and further comprising: A filter assembly is placed on one side of the oil filtration device body. The filter assembly includes a filter disposed on one side of the oil filtration device body. A baffle is provided on one side of the outer wall of the filter. A filter element is disposed inside the filter. A slide rail is connected to the side of the baffle near the filter element. A slider that is slidably connected to the slide rail is connected to one side of the filter element. A fixing component is placed on the outer surface of the filter assembly and is used to fix the filter and the baffle. The fixing component includes a retainer connected to the filter and the baffle on opposite sides. A U-shaped buckle is inserted inside the retainer. The baffle is engaged with the filter through the retainer and the buckle.

[0007] Furthermore, the card holders are arranged in an array around the outer surface of the baffle, and the card holders are arranged in the same direction on the baffle.

[0008] The advantages of adopting the above-mentioned further solution are: it prevents the baffle from deforming due to excessive local stress, thereby ensuring the stability of the baffle during use. At the same time, the buckles are inserted into the card slots in the same direction, which facilitates quick installation of the buckles.

[0009] Furthermore, a sealing gasket is provided between the inner wall of the baffle and the filter.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the filter and the baffle work together to squeeze the sealing gasket from both sides, sealing the gap between them, which helps to ensure the sealing effect between the filter and the baffle.

[0011] Furthermore, a limiting plate is connected to one end of the filter near the bottom of the baffle.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the limiting plate restricts the downward movement distance of the baffle through mechanical blocking, thereby ensuring the rapid alignment of the baffle with the filter, avoiding the baffle being installed too deep or too shallow, and improving the installation efficiency of the baffle.

[0013] Furthermore, a baffle plate is connected to the top of the filter, and a feed inlet is connected to the baffle plate.

[0014] The beneficial effect of adopting the above-mentioned further solution is that it aligns the outlet of the feed inlet with the axis of the filter element, allowing the insulating oil to quickly enter the interior of the filter element through the cooperation of the feed inlet and the partition.

[0015] Furthermore, the buckle has an anti-slip coating on the side near the card seat.

[0016] The beneficial effects of adopting the above-mentioned further solution are: preventing the buckle from accidentally coming off due to external forces, and improving the stability of the connection between the buckle and the card holder.

[0017] Furthermore, an elastic plate is connected to the outer side of the card holder near the buckle, and a snap-fit ​​groove is provided on the side of the buckle near the elastic plate. The buckle is snapped into the card holder through the elastic plate and the snap-fit ​​groove.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the elastic plate is engaged with both sides of the buckle by its own elasticity, which further improves the stability of the connection between the buckle and the buckle seat and enhances the vibration resistance of the fixing component.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This utility model, by setting up a filter assembly, allows for the removal of the baffle from the filter when the filter element becomes clogged or damaged during use. First, the baffle is released from its fixed position. Then, the baffle is pushed to move outwards from the filter. Since the filter element and baffle are connected by a slide rail and slider, the filter element will be removed from the filter along with the baffle. The filter element is then pushed to slide along the slide rail and separate, allowing for replacement. After maintenance, the baffle and filter are re-fixed to restore oil filtration. This achieves pull-out disassembly and assembly of the filter element, solving the problem of long maintenance time caused by multiple bolts fixing the end caps in traditional oil filtration devices. This improves the maintenance efficiency of the oil filtration device and reduces equipment downtime. 2. This utility model uses a fixing component to weld the mounting brackets to the corresponding positions of the baffle and the filter. When the baffle is installed on the filter, the buckle is inserted into the mounting bracket to fix the baffle on the filter. This prevents the baffle from accidentally separating from the filter during the oil filtration process, ensuring stable oil filtration. At the same time, it facilitates quick separation of the mounting bracket and the buckle, thereby improving the efficiency of separating the filter and the baffle and saving operation time for subsequent filter element maintenance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-6 As shown, this utility model provides a technical solution: an oil-immersed transformer oil filtration device, including an oil filtration device body 1. The oil filtration device body 1 consists of a mounting support frame, an oil pump, a vacuum degassing tank, a heating device, a vacuum pump, and a control unit. The mounting support frame provides installation space for each component and device. The oil pump provides power for oil circulation. The vacuum degassing tank separates oil from water and gas, increasing the surface area of ​​the oil. The heating device gently heats the oil to assist in water evaporation. The vacuum pump provides a high vacuum environment for the degassing tank. The control unit monitors various data of the oil filtration device body 1 and controls the start and stop of each device based on the data. It also includes: like Figures 1-4 As shown, filter assembly 2 is placed on one side of oil filter device body 1. Filter assembly 2 includes filter 21 disposed on one side of oil filter device body 1. A baffle 22 is provided on one side of the outer wall of filter 21. Filter element 23 is disposed inside filter 21. A slide rail 24 is connected to the side of baffle 22 near filter element 23. A slider 25 that is slidably connected to slide rail 24 is connected to one side of filter element 23. like Figures 5-6As shown, the fixing component 3 is placed on the outer surface of the filter component 2 and is used to fix the filter 21 and the baffle 22. The fixing component 3 includes a retainer 31 connected to the filter 21 and the baffle 22 on their respective sides. A U-shaped buckle 32 is inserted inside the retainer 31. The baffle 22 is engaged with the filter 21 through the retainer 31 and the buckle 32. By opening a groove on the filter 21 that matches the baffle 22, it is easy to seal the baffle 22 onto the filter 21. When the insulating oil enters the interior of the filter element 23, the filter holes on the filter element 23 filter the impurities in the insulating oil, achieving preliminary filtration of the insulating oil. When the filter element 23 becomes clogged or damaged during use, first release the fixing relationship between the baffle 22 and the filter 21, and then push the baffle 22 to move outward from the filter 21. Since the filter element 23 and the baffle 22 are connected by a slide rail 24 and a slider 25, the filter element 23 follows the baffle. Plate 22 is removed from inside filter 21, and then filter element 23 is pushed. Filter element 23 slides along slide rail 24 via slider 25 and separates, allowing filter element 23 to be replaced. After maintenance, baffle 22 and filter 21 are re-fixed to restore oil filtration. This achieves pull-out disassembly and assembly of filter element 23, simplifying the maintenance process of filter element 23. It solves the problem that oil filtration devices usually use multiple sets of bolts to fix the end caps, which increases the number of maintenance operations and prolongs the time. This is beneficial to improving the maintenance efficiency of oil filtration devices and reducing downtime. Furthermore, by welding the bracket 31 to baffle 22 and filter 21 respectively, when baffle 22 is installed on filter 21, the buckle 32 is inserted into the inside of the bracket 31 to ensure a firm connection between baffle 22 and filter 21, preventing baffle 22 from separating from filter 21 during oil filtration. At the same time, it also facilitates the separation of bracket 31 and buckle 32, improving the separation efficiency of filter 21 and baffle 22.

[0024] Furthermore, such as Figure 2 As shown, the card holders 31 are arranged in an array around the outer surface of the baffle 22. The card holders 31 are set in the same direction on the baffle 22. By inserting the buckles 32 into the card holders 31 around the baffle 22 in the same direction, the card holders 31 distribute the fixing force to the entire mating surface between the baffle 22 and the filter 21, preventing the baffle 22 from deforming due to excessive local force, thereby ensuring the stability of the baffle 22 during use. At the same time, the buckles 32 are inserted into the card holders 31 in the same direction, which facilitates quick installation of the buckles 32.

[0025] Furthermore, such as Figure 4As shown, a sealing gasket 26 is provided between the inner wall of the baffle 22 and the filter 21. By fitting the sealing gasket 26 onto the baffle 22, when the baffle 22 is fixed on the filter 21, the sealing gasket 26 is fixed to the inner side of the filter 21 along with the baffle 22. At this time, the filter 21 and the baffle 22 cooperate to squeeze the sealing gasket 26 from both sides, sealing the gap between them, thereby preventing the insulating oil from leaking from the gap, which helps to ensure the sealing effect between the filter 21 and the baffle 22.

[0026] Furthermore, such as Figure 2 As shown, a limiting plate 27 is connected to one end of the filter 21 near the bottom of the baffle 22. By welding the limiting plate 27 to the outer surface of the bottom end of the filter 21, the top surface of the limiting plate 27 is aligned with the groove on the filter 21. The limiting plate 27 restricts the downward movement distance of the baffle 22 through mechanical blocking, thereby ensuring that the baffle 22 and the filter 21 are quickly aligned, avoiding the baffle 22 from being installed too deep or too shallow, and improving the installation efficiency of the baffle 22.

[0027] Furthermore, such as Figure 3 As shown, a partition plate 29 is connected to the top of the inside of the filter 21. An inlet 28 is connected to the partition plate 29. By welding the partition plate 29 to the inside of the filter 21 and welding the inlet 28 to the partition plate 29, the outlet of the inlet 28 is aligned with the axis of the filter element 23. This allows the insulating oil to quickly enter the interior of the filter element 23 through the cooperation of the inlet 28 and the partition plate 29. At the same time, the bottom of the partition plate 29 is coated with a rubber coating to seal the gap between the partition plate 29 and the filter element 23, preventing the insulating oil from flowing out around the filter element 23.

[0028] Furthermore, such as Figure 6 As shown, the buckle 32 is provided with an anti-slip coating 33 on the side near the buckle seat 31. By spraying the anti-slip coating 33 onto the buckle 32, the friction between the buckle seat 31 and the buckle 32 is increased, preventing the buckle 32 from accidentally coming off due to external forces, which helps to improve the stability of the connection between the buckle seat 31 and the buckle 32.

[0029] Furthermore, such as Figure 6 As shown, an elastic plate 34 is connected to the outer side of the card holder 31 near the buckle 32. A snap-fit ​​groove 35 is provided on the side of the buckle 32 near the elastic plate 34. The buckle 32 is snapped into the card holder 31 through the elastic plate 34 and the snap-fit ​​groove 35. By fixing the elastic plate 34 to the card holder 31, when the buckle 32 moves towards the card holder 31, the buckle 32 squeezes the elastic plate 34 and causes the elastic plate 34 to deform. After the buckle 32 and the card holder 31 are fixed, the elastic plate 34 is snapped into both sides of the buckle 32 by its own elasticity, which further improves the stability of the connection between the buckle 32 and the card holder 31 and enhances the vibration resistance of the fixing component 3.

[0030] Working principle: such as Figures 1-5 As shown, the oil pump is first started to deliver insulating oil through the inlet 28 to the inside of the filter element 23. After filtering the insulating oil, the filter element 23 discharges the filtered insulating oil through the discharge port at the bottom into the heating device. The heating device heats the insulating oil to increase its fluidity. The heated oil then enters the vacuum tank and is diffused into a large surface area. Under high vacuum, the solubility of dissolved water and gas in the oil decreases, causing water and gas to escape from the oil and be extracted by the vacuum pump, thus completing the filtration of the insulating oil. When the filter element 23 becomes clogged or damaged during use, the buckle 32 is pulled to separate the buckle 32 from the seat 31. Then, the baffle 22 is pulled. The baffle 22, through the cooperation of the slide rail 24 and the slider 25, drives the filter element 23 out of the filter 21. Separate and push the filter element 23. The filter element 23 slides along the slide rail 24 via the slider 25, separating the filter element 23 from the baffle 22 and replacing it. Install the new filter element 23 on the baffle 22. Then, reset the baffle 22 and the filter element 23. The baffle 22 slides along the limiting plate 27 to prevent the baffle 22 from shifting. Finally, re-insert the buckle 32 into the inside of the card seat 31. The anti-slip coating 33 increases the friction between the buckle 32 and the card seat 31. The buckle 32 squeezes the elastic card plate 34 and causes the elastic card plate 34 to deform. After the buckle 32 and the card seat 31 are fixed, the elastic card plate 34 is engaged with both sides of the buckle 32 by its own elasticity. At this time, the baffle 22 and the filter 21 squeeze the sealing gasket 26, increasing the friction between them.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
