Description

Technical Field

[0001] This utility model belongs to the field of power transformer technology, and more specifically, it relates to a power transformer oil filtration device. Background Technology

[0002] Transformer oil, a mineral oil with excellent insulating properties, plays a vital role in power systems. It not only serves as a crucial insulating and heat-dissipating medium within transformers but also helps maintain stable transformer operation, ensuring the safe and stable operation of the power system. This makes transformer oil an indispensable electrical medium.

[0003] After long-term operation, transformer oil is prone to contamination with impurities such as metal shavings and insulation material fragments, which affects the transformer's heat dissipation efficiency and threatens the safe and stable operation of the equipment. Therefore, it is necessary to filter and purify the transformer oil. Existing transformer oil filtration devices have obvious defects in impurity removal: after impurities are intercepted, they tend to accumulate on the surface of the filter screen or in the internal chamber of the device. When removing impurities, the machine must be stopped and manually cleaned from inside the device. This operation is cumbersome and time-consuming. It not only affects the continuous operation of the power system, but frequent disassembly and assembly can also easily introduce new impurities and damage the device's sealing performance.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a filtration device for power transformer oil, including a treatment tank. The inner cavity of the treatment tank is divided into a storage chamber and a treatment chamber. The storage chamber is vertically located at the top of the storage chamber. A filter screen is installed in the treatment chamber to block impurities in the transformer oil to the top of the filter screen. A conveying component is provided in the treatment chamber to convey impurities on the surface of the filter screen to the storage chamber. A storage component is installed on one side of the treatment tank and is connected to the storage chamber. A cleaning component is installed at the lower end of the conveying component to clean the filter screen. A pushing component is installed at the upper end of the conveying component to push impurities in the storage chamber into the storage component.

[0006] The upper surface of the filter screen is inclined towards the axis so that the outer side of the filter screen is higher than its axis. The conveying assembly includes a conveying pipe that runs through and is installed on the bottom surface of the storage bin. The lower end of the conveying pipe is in contact with the upper surface of the filter screen, and the conveying pipe and the filter screen are coaxially arranged. Multiple feed troughs are evenly opened at the lower end of the conveying pipe. The upper end of the conveying pipe is located inside the storage bin, and multiple discharge ports are evenly arranged at the upper end of the conveying pipe. The conveying assembly also includes an auger that is coaxially and rotatably installed inside the conveying pipe. The outer circumference of the auger is in close contact with the inner wall of the conveying pipe, and a rotating rod is coaxially installed on the auger.

[0007] A drive unit is installed on the upper surface of the processing tank, and the drive end of the drive unit is connected to the upper end of the rotating rod.

[0008] The storage component includes a storage box, which is installed on the outer circumference of the processing tank. A connecting bend is installed at the upper end of the storage box, which communicates with the interior of the storage tank. One end of the connecting bend is connected to the bottom of the storage compartment and communicates with the interior of the storage compartment. An outlet is provided at the lower end of the storage box, and a cover plate is threaded onto the outlet.

[0009] The cleaning assembly includes a cleaning plate, one end of which is mounted on a rotating rod, and brushes are mounted on the upper surface of the cleaning plate, with the brushes all in contact with the lower surface of the filter screen.

[0010] The pushing component includes a connecting rod, one end of which is mounted on a rotating rod, and a pushing plate is mounted on the other end of the connecting rod. The lower end of the pushing plate contacts the bottom wall of the storage compartment cavity.

[0012] An output pipe is installed on the outer circumference of the processing tank, and the output pipe is connected to the lower end of the inner cavity of the processing tank.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model uses a drive device to rotate a rotating rod, which in turn rotates the auger. The impurities accumulated on the surface of the filter screen are transported to the storage chamber through a conveying pipe by the auger. They then enter the storage box through a connecting bend. This allows the device to automatically remove impurities from the processing chamber without stopping the equipment, eliminating the need to disassemble the equipment and manually remove impurities, thus improving work efficiency and the continuity of filtration operations.

[0015] 2. This utility model utilizes a rotating rod to synchronously drive the connecting rod and the pushing plate to rotate around the axis of the rotating rod, pushing impurities in the storage bin to facilitate their entry into the connecting bend, thereby increasing the speed at which impurities enter the storage bin and improving work efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] Please see Figure 1 , Figure 2 As shown:

[0027] This embodiment provides a filtration device for power transformer oil, including a processing tank 1. The inner cavity of the processing tank 1 is divided into a storage chamber 2 and a processing chamber 3. The storage chamber 2 is vertically located at its upper part. A filter screen 4 is installed inside the processing chamber 3. The operator inputs transformer oil into the upper part of the inner cavity of the processing chamber 3. The transformer oil falls through the filter screen 4 to the lower part of the inner cavity of the processing chamber 3. Impurities in the transformer oil are blocked above the filter screen 4, thereby separating the impurities inside the transformer oil. A conveying assembly 5 is provided inside the processing chamber 3. The lower end of the conveying assembly 5 contacts the upper surface of the filter screen 4, and the conveying assembly... Located above the storage chamber 2, the conveying component 5 can transport the impurities accumulated on the upper surface of the filter screen 4 to the storage chamber 2. A storage component 6 is installed on one side of the processing tank 1 and is connected to the storage chamber 2, allowing impurities to enter the storage component 6 for centralized storage. Operators only need to periodically remove the impurities collected in the storage component 6. This allows the device to remove impurities from the processing chamber 3 autonomously without stopping the equipment, eliminating the need for disassembly and reassembly of the equipment and manual removal of impurities, thus improving work efficiency and the continuity of filtration operations.

[0028] A cleaning component 7 is installed at the lower end of the conveying component 5, and a pushing component 8 is installed at the upper end of the conveying component 5. The conveying component 5 can synchronously drive the cleaning component 7 and the pushing component 8 to move. The movement of the cleaning component 7 can clean the filter screen 4, prevent the filter screen 4 from clogging, and ensure the filtration effect. The pushing component 8 can push impurities inside the storage compartment 2, making it easier for impurities to enter the storage component 6.

[0029] like Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, the upper surface of the filter screen 4 is inclined towards the axis, so that the outer side of the filter screen 4 is higher than its axis. This allows impurities accumulated on the upper surface of the filter screen 4 to be concentrated in the center of the filter screen 4 due to the inclination angle. The conveying assembly 5 includes a conveying pipe 9, which is installed through the bottom surface of the storage chamber 2. The lower end of the conveying pipe 9 is in contact with the upper surface of the filter screen 4, and the conveying pipe 9 and the filter screen 4 are coaxially arranged. Multiple feed troughs 10 are evenly opened at the lower end of the conveying pipe 9 so that impurities can enter the conveying pipe 9 through the feed troughs 10. The inclination of the upper surface of the filter screen 4 also facilitates the entry of impurities into the conveying pipe 9. The upper end of the conveying pipe 9 is located inside the storage chamber 2. The conveying assembly 5 is equipped with multiple discharge ports 11 evenly distributed. It also includes an auger 12, which is coaxially and rotatably installed inside the conveying pipe 9. The outer circumference of the auger 12 is in close contact with the inner wall of the conveying pipe 9. A rotating rod 13 is coaxially installed on the auger 12. A drive device 14 is installed on the upper surface of the processing tank 1. The drive end of the drive device 14 is connected to the upper end of the rotating rod 13. The operator starts the drive device 14, thereby driving the rotating rod 13 and the auger 12 to rotate inside the conveying pipe 9. This allows the impurities accumulated at the axial center of the upper surface of the filter screen 4 to be conveyed to the upper end of the conveying pipe 9 by the drive of the auger 12. The impurities then enter the storage bin 2 through the discharge port 11 and are collected in the storage assembly 6.

[0030] Multiple drain holes are evenly distributed on the auger 12. The design of the drain holes allows the transformer oil that is transported along with the impurities to the storage bin 2 to fall through the drain holes to the lower end of the transport pipeline 9, thereby improving the separation of transformer oil and impurities.

[0031] like Figure 2 , Figure 5 , Figure 6 As shown, the storage component 6 includes a storage box 15, which is installed on the outer circumference of the processing tank 1. A connecting bend 16 communicating with the interior is installed on the upper end of the storage box 15. One end of the connecting bend 16 is connected to the bottom surface of the storage chamber 2 and communicates with the interior of the storage chamber 2. An outlet is provided at the lower end of the storage box 15, and a cover plate 17 is threaded on the outlet. Impurities in the storage chamber 2 can enter the storage box 15 through the connecting bend 16 for centralized storage. The operator only needs to open the cover plate 17 periodically to remove the impurities inside the storage box 15 from the outlet. At the same time, the axial part of the bottom wall of the inner cavity of the storage chamber 2 is inclined outward, so that the outer side of the bottom wall of the inner cavity of the storage chamber 2 is lower than its axial position. The connecting bend 16 is connected to the lower horizontal position of the bottom wall of the inner cavity of the storage chamber 2. This design facilitates the entry of impurities into the connecting bend 16.

[0032] The pushing component 8 includes a connecting rod 21, one end of which is mounted on the rotating rod 13, and a pushing plate 22 is mounted on the other end of the connecting rod 21. The lower end of the pushing plate 22 contacts the bottom wall of the inner cavity of the storage compartment 2. When the driving device 14 drives the rotating rod 13 to rotate, the rotating rod 13 will simultaneously drive the connecting rod 21 and the pushing plate 22 to rotate around the axis of the rotating rod 13, pushing the impurities in the storage compartment 2 so that the impurities can enter the connecting bend 16 and be transported to the storage box 15 for centralized storage.

[0033] like Figure 2 , Figure 4 , Figure 6 As shown, the cleaning assembly 7 includes a cleaning plate 18, one end of which is mounted on a rotating rod 13. A brush 20 is mounted on the upper surface of the cleaning plate 18, and the brush 20 is in contact with the lower surface of the filter screen 4. When the driving device 14 drives the rotating rod 13 to rotate, the rotating rod 13 will synchronously drive the cleaning plate 18 to rotate around the axis of the rotating rod 13, thereby cleaning the filter screen 4 through the brush 20 to prevent impurities from clogging the filter screen 4 and to ensure the filtration effect of the filter screen 4.

[0034] like Figure 1 , Figure 2 As shown, an input pipe 23 is installed on the outer circumference of the processing tank 1, which communicates with the upper end of the inner cavity of the processing tank 1. An output pipe 19 is installed on the outer circumference of the processing tank 1, which communicates with the lower end of the inner cavity of the processing tank 1. The operator can transport the transformer oil to be filtered to the upper end of the processing chamber 3 through the conveying pipe. The transformer oil falls into the lower space of the processing chamber 3 below the filter screen 4. Impurities inside the transformer oil will be blocked above the filter screen 4, thereby filtering the transformer oil. The filtered transformer oil can be transported to the external storage tank 15 or enter the next processing step through the output pipe 19.

[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
