[0002] The principle of kerosene vapor phase drying is to use kerosene with a higher vaporization point than water as a medium to bring out the water in the dried material, thereby achieving the purpose of drying the dried material. The main components of the kerosene vapor phase drying equipment include kerosene steam generation system, kerosene steam condensation system, kerosene condensate recovery system, vacuum pump group, transformer oil tank and automatic control system. During the operation of the equipment, the heater combination heats the entire drying tank and the kerosene in the evaporator by heating the heat transfer oil to achieve the purpose of thoroughly drying the transformer. However, it is not easy to fix the transformer during the drying process, which causes the transformer to shift during drying and affects the heating. The waste kerosene and water vapor generated by the transformer drying are not easy to fall off, so they adhere to the transformer again and cause the transformer to become dirty, thereby increasing the difficulty of transformer drying. The used waste kerosene is not easy to collect, which makes it easy for the waste kerosene to splash everywhere when it is collected, thereby affecting the static and reuse of the waste kerosene. The transformer is not easy to take and place during the drying process, which causes the transformer to be placed out of place and affects the fixation.

[0003] In summary, the transformer is not easy to fix during the drying process, which causes the transformer to move during drying and affect the heating.

[0015] The present invention provides a kerosene gas phase equipment for transformer drying, which has the following beneficial effects: 1. The kerosene gas phase equipment for transformer drying comprises an evaporator, a placement plate and a clamping plate. The placement plate is horizontally installed inside the drying tank, so that the placement plate can horizontally place the transformer in contact with the placement plate, which is convenient for the heat to be driven by the circulation inside the drying tank to heat the transformer, and the clamping plate can adjust the clamping position according to the volume of the transformer, thereby increasing the clamping force of the clamping plate and preventing the transformer from being displaced during drying. The conveying component is connected to the evaporator, so that the evaporator works to heat the conveying component, which is convenient for the evaporator kerosene to be heated into kerosene vapor for heating, and the conveying component is not easy to bend or break when extracting the kerosene after standing on the collecting component, resulting in kerosene leakage.

[0016] 2. The kerosene gas phase equipment for transformer drying collects the filtered waste kerosene through a collecting tube. As the waste kerosene is left to stand, the kerosene and water flow are separated, which facilitates the discharge of water flow to drive impurities out of the collecting tube. The diverter frame corresponds to the feed port of the collecting tube, so that the diverter frame diverts the waste kerosene received, and then the diverter frame is used to buffer the flow of the waste kerosene on the collecting tube, avoiding the excessive impact force caused by the waste kerosene falling to damage the collecting tube, and preventing damage to the connection between the collecting tube and the filter assembly.

[0017] 3. The kerosene gas phase equipment for transformer drying supports the limiting block on the collecting cylinder through the fixing ring, so that the fixing ring can protect the installation position of the limiting block and prevent the connection position of the limiting block and the fixing ring from falling. When the buffer frame moves, it moves along the limiting block, so that the movement of the buffer frame can support the two limiting blocks, further improving the stability of the installation position of the limiting block, so that the buffer frame returns to the initial position to receive the waste kerosene that falls again.

[0018] 4. The kerosene gas phase equipment for transformer drying supports the guide shell through the support plate, which is convenient for the guide shell to guide the flow of waste kerosene when the buffer frame descends, thereby ensuring the convenience of the waste kerosene in the collection tube to stand still. Two detection columns are set on the support plate, which can detect the height of the waste kerosene collected by the collection tube in real time, so that the collection tube can discharge water and impurities after the waste kerosene is raised and lowered for a period of time, avoiding displacement of the support plate inside the collection tube.

[0019] 5. The kerosene gas phase equipment for transformer drying can be raised and lowered along the detection column as the waste kerosene increases, so that the cleaning ring can clean the detection column when it moves along the detection column, thereby ensuring the cleanliness of the detection column itself, and the support rod and the extrusion plate can cooperate to limit the height of the detection column, so that the extrusion plate can limit the moving height of the cleaning ring, which is convenient for the support rod and the extrusion plate to cooperate to reinforce the support plate and prevent the extrusion plate from loosening on the support plate.

[0020] 6. The kerosene gas phase equipment for transformer drying has a sealing plate through the transition tube, which is convenient for opening to observe the filter disc, avoiding the accumulation of too many impurities on the filter disc, resulting in blockage and affecting the circulation of waste kerosene. The cold air generated by the condenser circulates inside the transition tube through the condenser pipe, so that the condenser pipe condenses the waste kerosene and gas circulating inside the transition tube, ensuring the condenser pipe's effect on condensing gas and waste kerosene, so that the cold air discharged from the condenser pipe can fully contact the waste kerosene and gas for condensation.

[0021] 7. The kerosene gas phase equipment for transformer drying has two filter discs arranged inside the transition tube, which prevents the residual impurities from affecting the extraction of kerosene when the waste kerosene enters the collection tube, thereby ensuring the filtering effect of the filter disc on the waste kerosene. The pressure ring frame is located between the two filter discs, so that the pressure ring frame supports the filter disc on the transition tube, which is convenient for maintaining the activity space between the two filter discs and preventing the pressure ring frame and the filter disc from sliding on the transition tube.

[0022] 8. The kerosene gas phase equipment used for transformer drying supports the actuator inside the transition tube through the connecting plate, thereby increasing the bearing capacity of the middle solid rod itself, so that the contact between the middle solid rod and the filter disc restricts the filter disc, avoiding the displacement of the filter disc affecting the use. The push plate moves on the actuator under the thrust, so that the actuator drives the middle solid rod to rotate on the filter disc, making the movement of the push plate less susceptible to influence, and facilitating the control of the rotation of the middle solid rod according to the staff.

[0023] 9. The kerosene gas phase equipment used for transformer drying is driven by the middle solid rod to rotate through the cleaning frame, which is convenient for gathering impurities when cleaning the filter disc, ensuring that the filter disc is cleaned thoroughly. The linkage frame connects the cleaning frame and the middle solid rod, so that the linkage frame can protect the cleaning frame, avoiding the situation that the cleaning frame breaks or tilts when cleaning the filter disc, thereby increasing the cleaning effect of the cleaning frame. The linkage frame can increase the contact on the filter disc, so that the linkage frame stirs the waste kerosene when it contacts it.

[0024] 10. The kerosene gas phase equipment for transformer drying connects the collecting cylinder and the evaporator through a delivery pipe, so that the delivery pipe delivers the kerosene in the collecting cylinder to the evaporator for evaporation, which is convenient for the delivery pipe to deliver kerosene for transformer drying, so that the kerosene delivered by the delivery pipe can be reused, and the filter plate inside the inner support sleeve can filter the delivered kerosene, thereby avoiding the kerosene delivered by the delivery pipe containing too many impurities to affect the heating of the evaporator.

[0028] Example 1, please refer to Figure 1-Figure 12 The present invention provides a technical solution: a kerosene gas phase equipment for transformer drying, comprising a drying tank 1, wherein the drying tank 1 has a box door, and the box door is opened and closed on the drying tank 1 to place the transformer, so that the box door seals the drying tank 1, thereby ensuring that the drying tank 1 is subsequently vacuumed after the transformer is placed, avoiding the drying tank 1 from being affected when drying the transformer, and ensuring the sealing of the drying tank 1 before and after the transformer is placed. The top of the drying tank 1 is connected to a recovery pipe 5, and the outer surface of the drying tank 1 is connected to an extraction pipe 2, through which the waste kerosene of the drying transformer can be collected on the drying tank 1, so that the extraction pipe 2 can collect the waste kerosene. The oil and impurities are transported to the inside of the filter assembly 4, so that the waste kerosene is transported by the extraction pipe 2 to prevent the waste kerosene accumulated inside the drying tank 1 from contacting the transformer too much, and the extraction pipe 2 cooperates with the recovery pipe 5 to transport the gas inside the drying tank 1 inside the recovery pipe 5, so that the recovery pipe 5 can transport the gas to the inside of the filter assembly 4 for processing, ensuring that the filter assembly 4 filters the gas and waste kerosene when receiving them, avoiding the impurities contained in the waste kerosene from affecting the circulation of the liquid, and the extraction pipe 2 and the recovery pipe 5 collect the gas and waste kerosene from different positions to ensure the sealing effect of the connection position of the recovery pipe 5 and the extraction pipe 2, and also includes: A placement plate 9, which is fixedly connected to the inner surface of the drying tank 1, is used to place the transformer. The placement plate 9 is horizontally installed inside the drying tank 1, so that the placement plate 9 can horizontally place the transformer in contact with it, which is convenient for the internal circulation of the drying tank 1 to drive the heat to heat the transformer, and the placement plate 9 can cooperate with the two movable clamping plates 8, so that the placement plate 9 can guide the movement of the clamping plates 8, so that the clamping plates 8 can adjust the clamping position according to the volume of the transformer, thereby increasing the clamping force of the clamping plates 8, so that the clamping plates 8 can fix the transformer, thereby improving the stability of the transformer installation position, and preventing the transformer from being displaced during drying. The outer surface of the placement plate 9 is slidably connected with the clamping plate 8; The filter assembly 4 is connected to the end of the recovery pipe 5 away from the drying tank 1. The filter assembly 4 is used to filter the recovered waste kerosene and condense the gas. The waste kerosene condensed and filtered by the filter assembly 4 is transported to the collection assembly 3, so that the filter assembly 4 filters the gas and the waste kerosene to intercept impurities, which is convenient for the filter assembly 4 and the collection assembly 3 to cooperate with each other to collect the waste kerosene, and to facilitate the static separation of the collected waste kerosene, avoiding the collection assembly 3 from being affected when discharging water flow, and the filter assembly 4 can condense the gas and the waste kerosene, so that the water droplets generated by the gas condensation drip together with the waste kerosene, ensuring the treatment effect of the filter assembly 4 on the waste kerosene, and the bottom end of the filter assembly 4 is connected to The collecting component 3 has a conveying component 6 fixedly connected to its outer surface. The active space inside the collecting component 3 is extracted by the conveying component 6, so that the conveying component 6 circulates the processed kerosene from the collecting component 3, thereby ensuring the conveying component 6 to transport the kerosene. The conveying component 6 is connected to the evaporator 7, so that the evaporator 7 works to heat the conveying component 6, which is convenient for the evaporator 7 to heat the kerosene into kerosene vapor for heating. The connection between the conveying component 6 and the evaporator 7 can limit the installation position thereof, so that the conveying component 6 is not easy to bend or break when extracting the stationary kerosene on the collecting component 3, resulting in kerosene leakage. The conveying component 6 is connected to the evaporator 7 at a position away from the collecting component 3; The collecting assembly 3 includes a collecting cylinder 31, which is fixedly connected to the bottom end of the filtering assembly 4. The collecting cylinder 31 is used to collect and let the waste kerosene stand. The filtered waste kerosene is collected by the collecting cylinder 31, so that the waste kerosene stands inside the collecting cylinder 31. As the waste kerosene stands, the kerosene and the water flow are separated, so that the water flow and impurities are located below the kerosene, so that the collecting cylinder 31 can discharge the water flow after standing for a period of time, so that the water flow discharges and drives the impurities out of the collecting cylinder 31, thereby clearing the water flow and impurities inside the collecting cylinder 31. The collecting cylinder 31 can support the filtering assembly 4, thereby ensuring the stability of the filtering assembly 4 when it is working. A flow divider 32 is fixedly connected to the top of the inner cavity of 31. The flow divider 32 corresponds to the feed port of the collecting barrel 31, so that the flow divider 32 can divide the waste kerosene received, so that the waste kerosene can be diverted through the flow divider 32 to increase the circulation range, and then the flow divider 32 is used to buffer the circulation of the waste kerosene on the collecting barrel 31, so as to avoid the impact force generated by the waste kerosene falling and damaging the collecting barrel 31. The position where the flow divider 32 is connected to the collecting barrel 31 can reinforce the collecting barrel 31, thereby increasing the bearing capacity of the position where the collecting barrel 31 circulates the waste kerosene, and preventing the connection position between the collecting barrel 31 and the filter assembly 4 from being damaged. The outer surface of the collecting barrel 31 is fixedly connected with a guide shell 36; The fixing ring 33 is fixedly connected to the top of the inner cavity of the collecting tube 31, and the limiting block 34 is supported on the collecting tube 31 by the fixing ring 33, so that the two limiting blocks 34 are relatively installed inside the collecting tube 31, so that the fixing ring 33 can protect the installation position of the limiting block 34, thereby increasing the bearing capacity of the installation position of the limiting block 34, and preventing the connection position of the limiting block 34 and the fixing ring 33 from falling. The fixing ring 33 cooperates with the diverter frame 32 and the limiting block 34 to reinforce the collecting tube 31 at different positions, so that the installation position of the fixing ring 33 can limit the limiting block 34. The bottom of the fixing ring 33 is fixedly connected with the limiting block 34, and the side of the limiting block 34 away from the collecting tube 31 is fixedly connected with a buffer rod. 37, the top end of the buffer rod 37 is fixedly connected with a buffer frame 35, and the buffer frame 35 is subjected to the pressure of the waste kerosene to descend, so that the buffer frame 35 descends to squeeze the buffer rod 37, so that the buffer frame 35 and the buffer rod 37 cooperate to buffer the falling waste kerosene, thereby avoiding excessive impact force when the waste kerosene falls inside the collecting cylinder 31 and causing splashing, and the buffer frame 35 moves along the limiting block 34 during movement, so that the movement of the buffer frame 35 can support the two limiting blocks 34, further improving the stability of the installation position of the limiting block 34, when the buffer frame 35 loses the pressure of the waste kerosene, the buffer rod 37 extends to push the buffer frame 35 to rise, so that the buffer frame 35 returns to the initial position to receive the waste kerosene that falls again.

As the waste kerosene guided by the guide shell 36 approaches the conveying assembly 6, it is convenient for the rear conveying assembly 6 to extract the kerosene. The support of the guide shell 36 by the support plate 38 can increase the bearing capacity of the guide shell 36, prevent the guide shell 36 from being damaged by the impact when the waste kerosene falls, and thus extend the service life of the guide shell 36. The bottom of the support plate 38 is fixedly connected to the collecting cylinder 31. The squeezing plate 311 is fixedly connected to the top of the inner cavity of the support plate 38, and the bottom of the squeezing plate 311 is fixedly connected to a detection column 39. Two detection columns 39 are set on the support plate 38, so that the detection columns 39 can detect the waste kerosene collected by the collection cylinder 31 at different positions of the support plate 38, and can detect the height of the waste kerosene collected by the collection cylinder 31 in real time, so that the collection cylinder 31 can be convenient for the waste kerosene to be placed in a static state and the water flow and impurities can be discharged after a period of lifting, so that the subsequent conveying component 6 is not easily affected by the water flow when extracting kerosene The subsequent drying and detection column 39 reinforces the support plate 38, thereby increasing the bearing capacity of the support plate 38 itself and preventing the support plate 38 from being displaced inside the collecting tube 31. The outer surface of the detection column 39 is slidably connected with a cleaning ring 310, which is lifted and lowered along the detection column 39 as the waste kerosene increases, so that the cleaning ring 310 can clean the detection column 39 when it moves along the detection column 39, thereby ensuring the cleanliness of the detection column 39 itself and preventing the waste kerosene from adhering to the surface of the detection column 39 and causing the detection When the waste kerosene in the collecting tube 31 is reduced, the cleaning ring 310 is lowered, so that the cleaning ring 310 is lowered along the detection column 39 for cleaning again, thereby adjusting the cleaning position by using the cleaning ring 310 to move with the height of the waste kerosene collection, so that the cleaning ring 310 can clean the waste kerosene adhered to the detection column 39. The bottom end of the detection column 39 is fixedly connected to the support plate 38, and the bottom of the inner cavity of the support plate 38 is fixedly connected with a support rod 312, and the support rod 312 supports the extrusion plate 311 inside the support plate 38, so that The support rod 312 is vertically installed to tighten the extrusion plate 311, so that the vertical installation of the support rod 312 can be used to guide the movement of the cleaning ring 310, ensuring that the cleaning ring 310 moves along the detection column 39, and the support rod 312 cooperates with the extrusion plate 311 to limit the height of the detection column 39, so that the extrusion plate 311 limits the moving height of the cleaning ring 310, which makes it easier for the support rod 312 and the extrusion plate 311 to cooperate to reinforce the support plate 38 and prevent the extrusion plate 311 from loosening on the support plate 38.

[0033] The top end of the support rod 312 is fixedly connected to the extrusion plate 311 , and the outer surface of the support rod 312 is slidably connected to the cleaning ring 310 .

[0034] The filter assembly 4 includes a transition tube 41, which is connected to the top of the collecting tube 31. The transition tube 41 has a sealing plate, so that the sealing plate is pushed to slide on the transition tube 41 to reveal an opening, which is convenient for observing the filter disc 43 through the opening, and the opening position of the transition tube 41 can clean the impurities intercepted on the filter disc 43, avoiding excessive accumulation of impurities on the filter disc 43 to cause blockage and affect the circulation of waste kerosene. The sealing plate can seal the opening when the transition tube 41 moves, so that the transition tube 41 is not easy to splash to the outside when processing the waste kerosene, thereby improving the sealing inside the transition tube 41. The transition tube 41 gathers the waste kerosene and water vapor inside the drying tank 1, and the transition tube 4 1, a condenser 45 is fixedly connected to the top of the inner cavity of the transition tube 41, and the cold air generated by the condenser 45 flows through the condenser tube 42 inside the transition tube 41, so that the condenser tube 42 condenses the waste kerosene and gas flowing inside the transition tube 41, ensuring the effect of the condenser tube 42 on the condensation of gas and waste kerosene, and two condensers 45 are set, so that the condenser 45 fixes the condenser tube 42 from different positions, so that the two condensers 45 work at the same time to shorten the condensation time, and ensure that the condenser tube 42 is installed horizontally inside the transition tube 41, and the condenser tube 42 can circulate the cold air, so that the cold air discharged from the condenser tube 42 can fully contact the waste kerosene and gas for condensation, and the outer surface of the condenser 45 is connected with the condenser tube 42; The filter disc 43 is fixedly connected to the inner surface of the transition tube 41. The filter disc 43 is used to filter the waste kerosene and water vapor. Two filter discs 43 are arranged inside the transition tube 41, so that the filter discs 43 filter the waste kerosene, which avoids excessive residual impurities when the waste kerosene enters the collecting tube 31 and affects the subsequent kerosene extraction. The two filter discs 43 are distributed up and down to filter the waste kerosene twice, thereby ensuring the filtering effect of the filter disc 43 on the waste kerosene and preventing the waste kerosene flowing on the filter disc 43 from stopping and affecting the subsequent static state. The filter disc 43 can support the transition tube 41, which is convenient for maintaining the activity space inside the transition tube 41, so that the transition tube 41 is not easily damaged by pressure. The inner surface of the filter disc 43 is rotatably connected to a middle solid rod 46, and the filter disc 43 is fixedly connected to a pressure ring frame 44 at a position away from the middle solid rod 46. The pressure ring frame 44 is located between the two filter discs 43, so that the pressure ring frame 44 supports the filter disc 43 on the transition tube 41, so as to maintain the movable space between the two filter discs 43, and then the pressure ring frame 44 and the filter disc 43 are used to reinforce the transition tube 41 to prevent the pressure ring frame 44 and the filter disc 43 from slipping on the transition tube 41. The pressure ring frame 44 can support the filter disc 43 at different positions to ensure that the filter disc 43 is installed horizontally inside the transition tube 41, so that the filter disc 43 and the pressure ring frame 44 separate the inside of the transition tube 41.

[0035] The outer surface of the pressure ring frame 44 is fixedly connected to the transition tube 41 , and both ends of the middle fixing rod 46 extend to the outside of the filter disc 43 .

[0036] Among them, the outer surface of the middle solid rod 46 is fixedly connected with a linkage frame 410, and the cleaning frame 49 and the middle solid rod 46 are connected through the linkage frame 410, so that the linkage frame 410 can protect the cleaning frame 49, avoid the cleaning frame 49 from breaking or tilting when cleaning the filter plate 43, thereby increasing the cleaning effect of the cleaning frame 49, and the two linkage frames 410 cooperate with each other to limit the distance that the middle solid rod 46 penetrates the filter plate 43, avoiding the lifting and lowering of the middle solid rod 46 when rotating to affect the cleaning work of the cleaning frame 49, and the linkage frame 410 can increase the contact on the filter plate 43, so that the linkage frame 410 stirs the waste kerosene when it contacts The bottom of the linkage frame 410 is fixedly connected with a cleaning frame 49. The cleaning frame 49 is driven by the middle fixed rod 46 to rotate, so that the cleaning frame 49 moves along the filter disc 43 to push the impurities intercepted by the filter disc 43, which is convenient for gathering impurities when cleaning the filter disc 43, ensuring that the filter disc 43 is cleaned thoroughly, and the movement of the cleaning frame 49 on the filter disc 43 can clean the filter disc 43 to prevent the filter holes from being blocked after use, thereby improving the speed of the filter disc 43 to circulate the waste kerosene, so that the movement of the cleaning frame 49 can remove the waste kerosene remaining on the filter disc 43; The transmission device 48 is fixedly connected to the outer surface of the middle solid rod 46. The outer surface of the transmission device 48 is fixedly connected with a connecting plate 47. The transmission device 48 is supported inside the transition tube 41 by the connecting plate 47, so that the transmission device 48 can reinforce the middle solid rod 46, thereby increasing the bearing capacity of the middle solid rod 46 itself, and the connecting plate 47 cooperates with the transmission device 48 to limit the installation position of the middle solid rod 46, so that the connecting plate 47 is not easy to be displaced when the connecting plate 47 is installed horizontally, so that the connecting plate 47 and the middle solid rod 46 are fixed from different positions, so that the contact between the middle solid rod 46 and the filter disc 43 is limited to the filter disc 43, and the displacement of the filter disc 43 is avoided to affect the use, and the connecting plate The position of 47 away from the transmission device 48 is fixedly connected to the transition tube 41, and the side of the transmission device 48 away from the connecting plate 47 is slidably connected with a push plate 411. The push plate 411 is subjected to thrust and moves on the transmission device 48, so that the transmission device 48 drives the middle solid rod 46 to rotate on the filter disk 43, and the push plate 411 reciprocates on the transmission device 48 to limit the rotation direction of the middle solid rod 46, so that the middle solid rod 46 can rotate on the filter disk 43 in the clockwise and counterclockwise directions. The push plate 411 and the transmission device 48 are located between the two filter disks 43, so that the movement of the push plate 411 is not easily affected, so that it is convenient to control the rotation of the middle solid rod 46 according to the staff.

[0037] The inner surface of the cleaning frame 49 is fixedly connected to the middle fixing rod 46 , and the outer surface of the pushing plate 411 passes through the transmission device 48 .

[0038] The conveying assembly 6 includes a conveying pipe 61, which is fixedly connected to the outer surface of the collecting cylinder 31. The conveying pipe 61 is used to extract the kerosene stationary in the collecting cylinder 31. The collecting cylinder 31 is connected to the evaporator 7 through the conveying pipe 61, so that the conveying pipe 61 conveys the kerosene stationary in the collecting cylinder 31 to the evaporator 7 for evaporation, which is convenient for the conveying pipe 61 to convey the kerosene for drying the transformer, so that the kerosene conveyed by the conveying pipe 61 can be reused, and the conveying pipe 61 extends into the collecting cylinder 31, so that the conveying pipe 61 can directly extract the kerosene, which is convenient for the position of the conveying pipe 61 in the collecting cylinder 31 to be controlled by the guide shell 36 and the buffer frame 35. The inner surface of the delivery pipe 61 is fixedly connected with an inner support sleeve 62, and the opening of the delivery pipe 61 for kerosene to enter and exit can be reinforced by the inner support sleeve 62, thereby ensuring the position of the inlet of the delivery pipe 61, preventing the inlet of the delivery pipe 61 from being damaged by long-term contact with kerosene, and the filter plate 63 inside the inner support sleeve 62 can filter the delivered kerosene, thereby preventing the kerosene delivered by the delivery pipe 61 from containing too many impurities and affecting the heating of the rear evaporator 7, and then the filter plate 63 cooperates with each other on the inner support sleeve 62 to reinforce the inner support sleeve 62, thereby increasing the bearing capacity of the inner support sleeve 62 itself, and the inner surface of the inner support sleeve 62 is fixedly connected with the filter plate 63; The elastic plate 64 is fixedly connected to the top of the inner support sleeve 62. The elastic plate 64 is bent by the pressure of the waste kerosene when it flows, so that the bending of the elastic plate 64 drives the pressure plate 65 away from the filter plate 63, so that the bending of the elastic plate 64 can increase the activity space inside the inner support sleeve 62, thereby reducing the obstruction of the kerosene flowing inside the inner support sleeve 62. When the kerosene delivery stops, the elastic plate 64 is reset to drive the pressure plate 65 back to the initial position, so that the movement of the pressure plate 65 is used to restrict the filter plate 63. A pressure plate 65 is fixedly connected to the bottom of the force plate 64, and a collision block 66 is fixedly connected to the bottom of the pressure plate 65. The collision block 66 moves together with the pressure plate 65. As the pressure plate 65 is reset, the collision block 66 is driven to contact the filter plate 63 again, so that the collision block 66 knocks on the filter plate 63, thereby utilizing the vibration generated by the collision block 66 knocking on the filter plate 63 for self-cleaning, facilitating the falling of impurities adhered to the filter plate 63, avoiding blockage caused by excessive impurities adhered to the filter plate 63, and ensuring that the delivery pipe 61 continuously delivers kerosene.

[0039] Example 2, please refer to Figure 1-Figure 12On the basis of Example 1, the present invention provides a technical solution: a method for using a kerosene gas phase device for drying a transformer, step 1: open the upper door of the drying tank 1, and then place the transformer on the placement plate 9, the two clamping plates 8 are horizontally moved by the thrust on the placement plate 9 to clamp the transformer when they contact the transformer, the door of the drying tank 1 is closed and sealed, and after the drying tank 1 is closed and vacuumed, the kerosene inside the collecting cylinder 31 is transported to the inside of the evaporator 7 through the delivery pipe 61, so that the evaporator 7 heats the kerosene to become kerosene vapor and transport it to the inside of the drying tank 1, the kerosene vapor circulates inside the drying tank 1 to dry the transformer, and the gas generated by the transformer drying circulates to the recovery pipe 5; Step 2: Use the inner support sleeve 62 to support the inlet of the delivery pipe 61 for extracting kerosene, so that the kerosene flows along the delivery pipe 61 after being filtered by the filter plate 63. As the kerosene flows, the elastic plate 64 drives the pressure plate 65 to bend away from the filter plate 63, so that the pressure plate 65 drives the collision block 66 to move. When the delivery pipe 61 stops delivering kerosene, the elastic plate 64 drives the pressure plate 65 to reset, so that the pressure plate 65 drives the collision block 66 to knock on the filter plate 63, thereby dropping the impurities adhering to the filter plate 63; Step 3: The gas in the drying tank 1 is transported to the transition tube 41 through the recovery pipe 5, so that the condenser 45 transports cold air to the condensation pipe 42 in the transition tube 41, so that the condensation pipe 42 condenses the gas, and the gas falls onto the filter plate 43 after condensation, so that the filter plate 43 filters the water flow, and the pressure ring frame 44 supports the filter plate 43 on the transition tube 41. After the drying tank 1 dries the transformer, the waste kerosene in the drying tank 1 is transported to the transition tube 41 through the extraction pipe 2, so that the waste kerosene is condensed by the condensation pipe 42 and falls onto the filter plate 43, so that the filter plate 43 filters the waste kerosene and the condensed water flow together; Step 4: Use the collecting cylinder 31 to collect the waste kerosene processed inside the transition cylinder 41, so that the waste kerosene is diverted by the diverting rack 32 and then falls onto the buffer rack 35. The buffer rack 35 is squeezed by the pressure of the waste kerosene to shrink the buffer rod 37, and the buffer rack 35 slides down on the limiting block 34. As the waste kerosene flowing through the buffer rack 35 flows along the guide shell 36, the collecting cylinder 31 allows the collected waste kerosene to remain stationary. When the buffer rack 35 loses the pressure of the waste kerosene, the buffer rod 37 extends to push the buffer rack 35 up to reset. Step 5: Use the support plate 38 to support the guide shell 36, so that the detection column 39 inside the support plate 38 detects the height of the waste kerosene collected by the collection tube 31. The waste kerosene is gradually collected inside the collection tube 31, and the cleaning ring 310 is pushed up along the detection column 39 and the support rod 312, so that the cleaning ring 310 cleans the outer surface of the detection column 39, and the support rod 312 supports the extrusion plate 311 inside the support plate 38, so that the extrusion plate 311 fixes the detection column 39. After the waste kerosene is left to stand, the standing water flow is separated from the kerosene, and the water flow and impurities at the bottom are discharged from the collection tube 31, while the kerosene at the top is stored inside the collection tube 31; Step six: open the door of the drying tank 1 to push the clamping plate 8 away from the transformer, and then take out the transformer. The sealing plate on the transition tube 41 is rotated by the thrust, so that the transition tube 41 reveals an opening. As the pushing plate 411 applies thrust, the pushing plate 411 pushes the transmission 48 to drive the middle solid rod 46 to rotate. The rotation of the middle solid rod 46 drives the linkage frame 410 and the cleaning frame 49 to rotate, so that the cleaning frame 49 moves along the filter disc 43 to gather impurities on the filter disc 43, and then removes impurities from the opening of the transition tube 41 to clean the two filter discs 43.
