Description

Technical Field

[0001] This utility model relates to the field of transformer oil treatment technology, and specifically to a transformer oil treatment and regeneration device. Background Technology

[0002] Transformer oil is a critical insulating and cooling medium in high-voltage electrical equipment such as power transformers and reactors, and its performance is crucial to the safe operation and service life of the equipment. During long-term operation, transformer oil is affected by factors such as high temperature, electric field, oxygen, and moisture, leading to oxidative aging and the production of impurities such as acidic substances, oxidized colloids, moisture, and solid particles. These impurities can cause a decrease in the dielectric strength of the oil and an increase in dielectric loss, thus affecting the reliability of the equipment. To restore the performance of aged transformer oil and extend its service life, regeneration is usually required. Traditional regeneration methods include clay adsorption, acid-base refining, and vacuum filtration. Among these, clay adsorption is widely used in industrial practice due to its relatively simple operation and low cost. This method typically involves heating activated clay and adding it to the simultaneously heated aged oil, stirring at a suitable temperature, and utilizing the adsorption effect of the clay to remove polar impurities from the oil. Subsequently, filtration separates the clay and its adsorbate, thus purifying the oil. In this operation mode, the amount of clay added is usually determined manually based on empirical formulas for the initial state of the oil (such as acid value and dielectric loss) or batch size, and added all at once. In actual production, the degree of aging of oil products may vary from batch to batch or even within the same batch in a localized area. The fixed amount of bleaching clay added at one time is difficult to dynamically adjust according to the real-time conditions during the adsorption process, which may result in insufficient bleaching clay usage and affect the purification effect.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a transformer oil treatment and regeneration device to solve the technical problem that the degree of aging of oil products may vary from batch to batch or there may be local differences within the same batch in the tank, and the fixed amount of white clay added at one time is difficult to dynamically adjust according to the real-time situation during the adsorption process, which may lead to insufficient white clay usage affecting the purification effect.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: A transformer oil treatment and regeneration device is provided, comprising: a quantitative addition component, the quantitative addition component including: a discharge section having an inlet end and a discharge end; a first sealing section disposed at the inlet end; and a second sealing section disposed at the discharge end; the first sealing section and the second sealing section having a first state and a second state; wherein, when in the first state, the first sealing section blocks the inlet end, and the second sealing section avoids the discharge end; when in the second state, the first sealing section avoids the inlet end, and the second sealing section blocks the discharge end.

[0006] Furthermore, the transformer oil treatment and regeneration device also includes a treatment tank, and the quantitative addition component includes: a discharge channel having an inlet end and an outlet end, the outlet end of the discharge channel being located inside the treatment tank; a first sealing member movably disposed at the inlet end; and a second sealing member movably disposed at the outlet end; wherein the first sealing member forms a first sealing portion; and the second sealing member forms a second sealing portion.

[0007] Furthermore, the quantitative addition component also includes: a U-shaped frame, the open end of which is connected to a second sealing member, the U-shaped frame and the second sealing member forming a discharge channel; wherein, when in the first state, the discharge channel is connected to the discharge end.

[0008] Furthermore, the quantitative addition component also includes: a telescopic member, which is installed on the processing tank. The telescopic end of the telescopic member is movably inserted through the outer wall of the processing tank in the radial direction. The telescopic end of the telescopic member is drivenly connected to the first sealing member and the second sealing member, respectively, so as to drive the movement of the first sealing member and the second sealing member through the telescopic member. Furthermore, the quantitative addition component also includes: a storage tank, which has a storage space and a discharge channel located at the bottom of the storage tank, communicating with the discharge channel; the first sealing member is movably located at the bottom of the storage tank for sealing or opening the discharge channel.

[0009] Furthermore, the transformer oil treatment and regeneration device also includes a stirring assembly, which is rotatably disposed inside the treatment tank for stirring the transformer oil and treatment agent inside the treatment tank.

[0010] Furthermore, the mixing assembly includes: a transmission rod rotatably disposed inside the processing tank, the transmission rod extending vertically, and the transmission rod being spaced apart from the discharge channel; a mixing rod connected to the transmission rod; and a mixing head disposed at the end of the mixing rod away from the transmission rod.

[0011] Furthermore, the stirring head includes: a stirring ring disposed at the end of the stirring rod away from the transmission rod; and an extension cylinder disposed on one side of the stirring ring. Furthermore, the transformer oil treatment and regeneration device also includes: a cover body detachably disposed from the treatment tank; the stirring assembly further includes: a drive unit mounted on the cover body, the output end of the drive unit being drivenly connected to the transmission rod, so as to drive the transmission rod, stirring rod, and stirring head to rotate, thereby stirring the transformer oil and treatment agent in the treatment tank.

[0012] Furthermore, the cover includes a first cover and a second cover, the first cover being disposed on the top of the storage hopper, and the second cover being rotatably disposed relative to the first cover, the second cover being located on the top of the storage hopper.

This solution overcomes the shortcomings of traditional methods that require fixed, one-time addition, allowing for small-batch, multiple additions according to treatment needs. This enables more flexible adaptation to differences in oil aging levels, optimizes treatment agent dosage, and improves purification efficiency.

[0015] 2. By setting up a U-shaped frame connected to the second sealing component, the two together form a discharge channel.

This scheme ensures that the quantitatively released treatment agent can be effectively collected and guided to the target location (such as inside the treatment tank), preventing spillage and improving the accuracy and reliability of addition.

[0016] 3. By incorporating a telescopic component (such as a pneumatic or hydraulic cylinder) and moving its telescopic end radially along the processing tank, simultaneously driving the first and second sealing components, centralized and synchronous control of their movement is achieved. This solution simplifies operation; simply controlling the extension and retraction of the telescopic component allows for precise switching between the states (first or second state) of the first and second sealing components, improving the convenience and efficiency of quantitative addition operations.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] According to an embodiment of this utility model, a transformer oil treatment and regeneration device is provided. Please refer to [link / reference]. Figures 1 to 4 The device includes: a quantitative addition component 1, which includes: a discharge section having an inlet end and a discharge end; a first sealing section disposed at the inlet end; and a second sealing section disposed at the discharge end. The first sealing section and the second sealing section have a first state and a second state. In the first state, the first sealing section blocks the inlet end, and the second sealing section avoids the discharge end. In the second state, the first sealing section avoids the inlet end, and the second sealing section blocks the discharge end.

[0025] By adopting the above technical solution, and by setting up a quantitative addition component 1 with a first sealing section and a second sealing section, and switching between the two in a first state (inlet end sealing, outlet end avoidance) and a second state (inlet end avoidance, outlet end sealing), precise quantitative control of the treatment agent (such as activated clay) flowing out of the outlet section is achieved. This solution overcomes the shortcomings of traditional methods that require fixed addition at one time, allowing for small-batch, multiple additions according to treatment needs. This enables more flexible adaptation to differences in oil aging, optimizes the dosage of treatment agent, and improves purification efficiency.

[0026] Please refer to Figure 1 and Figure 4 The transformer oil treatment and regeneration device also includes a treatment tank 2, which is equipped with a first heating element for heating the transformer oil. The quantitative addition component 1 includes: a discharge channel 3, which has an inlet end and a discharge end, with the discharge end of the discharge channel 3 located inside the treatment tank 2; a first sealing member 4, which is movably disposed at the inlet end; and a second sealing member 5, which is movably disposed at the discharge end. The first sealing member 4 forms a first sealing part; the second sealing member 5 forms a second sealing part; and the discharge channel 3 forms a discharge part.

[0027] Furthermore, the first sealing member 4 and the second sealing member 5 have a first state and a second state; wherein, when in the first state, the first sealing member 4 closes the feed end and the second sealing member 5 opens the discharge end; when in the second state, the first sealing member 4 opens the feed end and the second sealing member 5 closes the discharge end.

[0028] By adopting the above technical solution, and specifically setting movable first sealing element 4 and second sealing element 5 to control the inlet and outlet ends of the discharge channel 3 respectively, and switching between a first state (first sealing element 4 closes the inlet end, second sealing element 5 opens the outlet end) and a second state (first sealing element 4 opens the inlet end, second sealing element 5 closes the outlet end), the temporary storage and quantitative release of the treatment agent (such as activated clay) in the discharge channel 3 are realized. This solution provides a specific actuator for the precise and batch-wise addition of the treatment agent, facilitating dynamic control.

[0029] Please refer to Figure 4 The quantitative addition component 1 also includes: a U-shaped frame 6, the open end of which is connected to the second sealing member 5, and the U-shaped frame 6 and the second sealing member 5 form a feeding channel; wherein, when in the first state, the feeding channel is connected to the discharge end.

[0030] By adopting the above technical solution, and by setting up a U-shaped frame 6 connected to the second sealing component 5, the two together form a discharge channel. In the first state, this discharge channel is connected to the discharge end of the discharge channel 3, providing a guiding and containing channel for the treatment agent (such as activated clay) released from the discharge channel 3. This solution ensures that the quantitatively released treatment agent can be effectively collected and guided to the target location (such as inside the treatment tank 2), preventing spillage and improving the accuracy and reliability of the addition.

[0031] Preferably, the discharge channel 3 is a discharge cylinder.

[0032] Furthermore, when in the first state, the feeding channel is located directly below the discharge end.

[0033] Furthermore, the first sealing element 4 and the U-shaped frame 6 are connected at the ends away from the second sealing element 5.

[0034] Please refer to Figure 1 and Figure 4 The quantitative addition component 1 also includes: a telescopic member 7, which is installed on the processing tank 2. The telescopic end of the telescopic member 7 is movably inserted through the outer wall of the processing tank 2 in the radial direction. The telescopic end of the telescopic member 7 is driven to be connected to the first sealing member 4 and the second sealing member 5 respectively, so as to drive the first sealing member 4 and the second sealing member 5 to move through the telescopic member 7.

[0035] By adopting the above technical solution, and by setting up a telescopic component 7 (such as a pneumatic or hydraulic cylinder) and moving its telescopic end radially along the processing tank 2, while simultaneously driving the first sealing component 4 and the second sealing component 5, centralized and synchronous control of the movement of the first sealing component 4 and the second sealing component 5 is achieved. This solution simplifies the operation; only the extension and retraction of the telescopic component 7 needs to be controlled to precisely switch the state (first state or second state) of the first sealing component 4 and the second sealing component 5, improving the convenience and efficiency of quantitative addition operations.

[0036] Specifically, the telescopic end of the telescopic component 7 is connected to the vertical plate. The vertical plate has a first horizontal plate and a second horizontal plate on the side facing the U-shaped frame 6. The first horizontal plate is connected to the first sealing component 4, and the second horizontal plate is connected to the U-shaped frame 6. The length of the first horizontal plate is longer than that of the second horizontal plate, but the length of the first horizontal plate is shorter than the length of the second horizontal plate plus the length of the U-shaped frame 6. That is, the second sealing component 5 is closer to the central axis of the treatment tank 2 than the first sealing component 4. The telescopic component 7 pushes the vertical plate towards the central axis of the treatment tank 2, thereby driving the first horizontal plate and the second horizontal plate to drive the first sealing component 4 and the second sealing component 5 to move respectively. At this time, the first sealing component 4 blocks the discharge channel 3, the second sealing component 5 is located on one side of the discharge channel 3, the U-shaped frame 6 is located below the discharge channel 3, and the discharge channel is located directly below the discharge channel 3 to facilitate the flow of activated clay.

[0037] Please refer to Figure 4 The quantitative addition component 1 also includes: a storage tank 8, which has a storage space, and a discharge channel 3 is located at the bottom of the storage tank 8, with the storage space connected to the discharge channel 3; and a first sealing member 4 is movably located at the bottom of the storage tank 8 for sealing or opening the discharge channel 3.

[0038] By adopting the above technical solution, a storage tank 8 is set up with a discharge channel 3 at its bottom, connecting the storage space of the storage tank 8 with the discharge channel 3, providing a centralized storage space for the treatment agent (such as activated clay). Simultaneously, the opening and closing of the inlet end of the discharge channel 3 is controlled by a first sealing component 4 movably set at the bottom of the storage tank 8, enabling on-demand supply of the treatment agent from the storage space to the discharge channel 3, thus ensuring material availability for subsequent quantitative addition.

[0039] Furthermore, a second heating element is provided inside the storage tank 8 for heating the activated clay.

[0040] By adopting the above technical solution and installing a second heating element inside the storage tank 8, the treatment agent (such as activated clay) stored in the storage tank 8 is preheated before being added. This solution ensures that the activated clay reaches a suitable working temperature before entering the treatment tank 2, which is beneficial for maintaining and maximizing its adsorption activity, thereby improving its purification efficiency during subsequent stirring.

[0041] Please refer to Figure 1 The transformer oil treatment and regeneration device also includes a stirring assembly 9, which is rotatably disposed inside the treatment tank 2 for stirring the transformer oil and treatment agent inside the treatment tank 2.

[0042] By adopting the above technical solution, and by installing a rotatable stirring component 9 inside the treatment tank 2, the aged transformer oil and the treatment agent (such as preheated activated clay) added to the treatment tank 2 are thoroughly stirred and mixed. This solution promotes full contact between the treatment agent and impurities in the oil, improving adsorption efficiency and regeneration effect.

[0043] Please refer to Figure 2 The stirring assembly 9 includes: a transmission rod 10, which is rotatably disposed inside the processing tank 2 and extends vertically, and is spaced apart from the discharge channel 3; a stirring rod 11, which is connected to the transmission rod 10; and a stirring head 12, which is disposed at the end of the stirring rod 11 away from the transmission rod 10.

[0044] By adopting the above technical solution, the core working part of the stirring assembly 9 is constituted by setting a vertically extending transmission rod 10, a stirring rod 11 connected to the transmission rod 10, and a stirring head 12 set at the end of the stirring rod 11. This solution provides an effective stirring structure. The transmission rod 10 transmits power, and the stirring rod 11 and the stirring head 12 work together to agitate the transformer oil and treatment agent mixture in the treatment tank 2, ensuring uniform mixing.

[0045] Please refer to Figure 2The stirring head 12 includes: a stirring ring 13, which is disposed at the end of the stirring rod 11 away from the transmission rod 10; and an extension cylinder 14, which is disposed on one side of the stirring ring 13.

[0046] Furthermore, the hollow portion of the stirring ring 13 corresponds to the hollow portion of the extension cylinder 14.

[0047] By adopting the above technical solution, and by setting a stirring ring 13 with a hollow section and an extension cylinder 14, with their hollow sections corresponding to each other, a special stirring head 12 structure is formed. This solution enables the stirring head 12 to generate a more complex flow field when rotating, enhancing the shearing and turbulence effect on the oil and treatment agent mixture, further promoting the dispersion of treatment agent particles and their contact with impurities in the oil, and improving mixing uniformity and adsorption efficiency.

[0048] Please refer to Figure 1 The transformer oil treatment and regeneration device also includes: a cover 15, which is detachably mounted on the treatment tank 2; the stirring assembly 9 also includes: a drive unit 18, which is mounted on the cover and whose output end is driven to the transmission rod 10 so as to drive the transmission rod 10, the stirring rod 11, and the stirring head 12 to rotate so as to stir the transformer oil and treatment agent in the treatment tank 2.

[0049] By adopting the above technical solution, a cover 15 is detachably connected to the processing tank 2, and a drive component 18 (such as a motor) is installed on the cover 15. The output end of the drive component 18 is connected to the transmission rod 10, providing a power source for the stirring assembly 9. This solution automates the stirring action. The drive component 18 drives the stirring rod 11 and the stirring head 12 to rotate through the transmission rod 10, performing efficient stirring operations. At the same time, the detachability of the cover 15 facilitates the maintenance and cleaning of the equipment.

[0050] Please refer to Figure 1 The cover 15 includes a first cover 16 and a second cover 17. The first cover 16 is disposed on the top of the storage tank 8, and the second cover 17 is rotatably disposed relative to the first cover 16. The second cover 17 is located on the top of the storage tank 8.

[0051] By adopting the above technical solution, and by configuring the cover 15 to include a first cover 16 fixed to the top of the storage tank 8 and a second cover 17 rotatable relative to the first cover 16, a flexible sealing method is provided for the top of the storage tank 8. This solution allows the second cover 17 to be rotated open, facilitating the addition of treatment agents (such as activated clay) into the storage tank 8. After adding the treatment agent, closing the second cover 17 maintains the sealed environment of the storage tank 8, which is beneficial for maintaining the drying and preheating effect of the treatment agent.

[0052] Working principle:

[0053] At the start of operation, rotate and open the second cover 17 located on top of the storage tank 8, add sufficient activated clay into the storage space of the storage tank 8, and then close the second cover 17; activate the second heating element inside the storage tank 8 to preheat the activated clay, and simultaneously activate the first heating element inside the treatment tank 2 to heat the injected aged transformer oil to a suitable adsorption temperature; when both the oil and activated clay reach the required temperature, operate the telescopic component 7 to move its telescopic end toward the central axis of the treatment tank 2, pushing the first sealing component 4 connected thereto to close. At the inlet end of the discharge channel 3, the second sealing member 5 and the U-shaped frame 6 connected to it are simultaneously moved, causing the second sealing member 5 to open the discharge end of the discharge channel 3, and the discharge channel formed by the U-shaped frame 6 and the second sealing member 5 is located directly below the discharge end (at this time, it is in the first state). At this time, the preheated activated clay flows from the storage tank 8 into the discharge channel 3 and is temporarily stored there; then, the telescopic member 7 is operated in the opposite direction, so that its telescopic end moves away from the central axis of the processing tank 2, driving the first sealing member 4 to open the inlet end of the discharge channel 3 (allowing subsequent...). (Replenishment of activated clay), while simultaneously driving the second sealing component 5 to close the discharge end of the discharge channel 3 (at this time in the second state), thereby cutting off and releasing the quantitative volume of activated clay temporarily stored in the discharge channel 3. This quantitative amount of activated clay is added to the hot oil in the treatment tank 2 through the discharge channel of the U-shaped frame 6. According to the oil quality and treatment effect monitoring, the telescopic component 7 can be repeatedly operated to switch between the first and second states to realize multiple small-batch quantitative dynamic addition of activated clay. After each addition of activated clay or during the addition process, the drive component 18 installed on the first cover 16 is activated, driving the transmission rod 10, stirring rod 11 and stirring head 12 (including stirring ring 13 with corresponding hollow parts and extension cylinder 14) to rotate in the treatment tank 2, strongly stirring the mixture of hot oil and activated clay. The special structure of the stirring head 12 generates enhanced shearing and eddy currents, promoting the dispersion of activated clay particles and their full contact and adsorption with impurities in the oil. After adsorption is completed, stirring and heating are stopped, and the mixture is allowed to stand for separation or undergo subsequent filtration operations to finally obtain regenerated and purified transformer oil, which can be released through the drain port.
