Description

Technical Field

[0001] The present application relates to the technical field of transformer production, and in particular to a liquid immersion processing device for transformer production. Background Art

[0002] At present, the coil of the transformer needs to be impregnated with insulating varnish after winding and then dried. Most of the current processing methods are to manually move the coil to a vacuum tank, close the door of the vacuum tank, and then use a vacuum pump to evacuate the tank and perform related immersion operations.

[0003] The current method requires waiting for vacuuming. Generally speaking, vacuuming takes more than ten minutes. And every time the vacuum tank is opened, the negative pressure environment inside it disappears, and it needs to be vacuumed again after it is closed again, which leads to reduced efficiency and high energy consumption of the entire production process, and is also extremely cumbersome.

DETAILED DESCRIPTION

[0034] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0036] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0037] The terms "comprising" and "having" and any variations thereof in the description and claims of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that comprises a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0038] One preferred embodiment of this application is, as Figures 1 to 16 shown, an impregnating processing device for transformer production, comprising an impregnating tank 1, a feeding tank 2 and a displacement device 300. The overall structure of the impregnating tank 1 is narrower at the top and wider at the bottom; specifically, a lower part of the impregnating tank 1 is provided with an impregnating cavity 100 for containing paint liquid, and an upper part of the impregnating tank 1 is provided with a vertical sliding cavity 101. The feeding tank 2 can be vertically and sealingly slidably installed in the sliding cavity 101, and one of the wider vertical sides of the feeding tank 2 is provided with a feeding cavity 200 for placing a transformer coil 01, that is, the cross-sectional structure of the feeding tank 2 is in the shape of "凵". The displacement device 300 is installed outside the impregnating tank 1 and is connected to the feeding tank 2 through an output end, and thus the feeding tank 2 can perform a vertical and sealing movement along the sliding cavity 101 under the drive of the displacement device 300, so as to drive the transformer coil 01 placed in the feeding cavity 200 into the impregnating cavity 100 to complete paint impregnation. During the movement of the feeding tank 2, the bottom and / or the top of the feeding tank 2 always maintains a seal with the sliding cavity 101.

[0039] For the convenience of understanding, the process of the feeding tank 2 carrying the transformer coil 01 for feeding and paint impregnation can be described in detail below.

[0040] When feeding the transformer coil 01, the feeding tank 2 is at the highest position. At this time, the feeding tank 2 can be sealed with the sliding cavity 101 through the bottom end, so that the impregnating cavity 100 is in a relatively sealed state. After the feeding of the transformer coil 01 is completed, the feeding tank 2 can perform a vertical movement under the drive of the displacement device 300; during this process, the feeding tank 2 can maintain the seal of the bottom end with the sliding cavity 101 so that the impregnating cavity 100 is always in a sealed state. When the bottom of the feeding tank 2 is about to cross the sliding cavity 101 and enter the impregnating cavity 100, the top end of the feeding tank 2 just makes a sealing fit with the upper end of the sliding cavity 101; then as the feeding tank 2 continues to move downward, the feeding tank 2 can carry the transformer coil 01 in the placing cavity 200 and immerse it in the paint liquid, and at the same time the feeding tank 2 can continue to maintain the seal with the sliding cavity 101 through the top end so that the impregnating cavity 100 is always in a relatively sealed state. After the impregnation is completed, the above process can be reversed.

[0041] It can be understood that, from the above-mentioned process of loading and immersing the transformer coil 01, the immersion chamber 100 is always in a relatively sealed state; and in the process of unloading and reloading the transformer coil 01 after the immersion, the pressure change in the immersion chamber 100 only increases the volume of air after the discharge box 2 is connected to the outside world. Therefore, in the vacuuming process after the loading is completed, it is only necessary to extract the air corresponding to the volume of the discharge box 2. Since the volume of the discharge box 2 is much smaller than the volume of the immersion chamber 100, the vacuuming time can be effectively shortened to improve the production efficiency of the transformer coil 01.

[0042] It should be known that a vacuum pump 600 for evacuating the immersion chamber 100 is installed on one side of the immersion tank 1. During the first operation, the vacuum pump 600 needs to evacuate the immersion chamber 100 to a set vacuum degree, which takes a long time. In the subsequent operation, the vacuum pump 600 only needs to discharge the air brought into the immersion chamber 100 during the loading process of the discharge chamber 200 each time.

[0043] In this embodiment, the specific structure and working principle of the displacement device 300 are well known to those skilled in the art. Common displacement devices 300 include air cylinders, hydraulic cylinders, and linear motors. In this embodiment, a hydraulic cylinder is preferably used. In order to ensure that the displacement device 300 drives the discharge box 2 stably and safely, the number of displacement devices 300 can be set to multiple, for example Figure 1 , Figure 3 and Figure 4 As shown, there are two displacement devices 300, which are symmetrically arranged on opposite sides of the immersion box 1. At the same time, a connecting frame 21 extending to both sides is arranged on the top of the discharge box 2; the two displacement devices 300 are respectively connected to the two ends of the connecting frame 21 through the output end, and then the entire discharge box 2 is driven to move vertically by driving the connecting frame 21.

[0044] In this embodiment, in order to further improve the immersion efficiency and immersion quality of the transformer coil 01, an air pressure regulating component 5 can also be installed. The air pressure regulating component 5 can evacuate the immersion chamber 100 when the discharge box 2 carries the transformer coil 01 to move downward for immersion, so as to accelerate the reduction of the air pressure in the immersion chamber 100 to the set vacuum requirement. When the discharge box 2 moves upward, the air pressure regulating component 5 can also discharge the previously extracted and stored gas to the sliding chamber 101 and directly face the transformer coil 01 that has been dipped in the paint in the discharge chamber 200, thereby accelerating the drying process of the paint liquid by increasing air flow.

[0045] Specifically, Figure 1 and Figure 5As shown, an air pressure regulating component 5 is also installed on the outside of the immersion box 1 and is driven by the discharge box 2; the air suction end of the air pressure regulating component 5 is connected to the immersion chamber 100, and the air exhaust end of the air pressure regulating component 5 is connected to the sliding chamber 101; when the discharge box 2 moves downward, the air pressure regulating component 5 can evacuate the immersion chamber 100 through the air suction end; when the discharge box 2 moves upward, the air pressure regulating component 5 can discharge the extracted gas to the discharge chamber 200 located in the sliding chamber 101.

[0046] There are many specific structures of the air pressure regulating assembly 5 that can achieve the above functions, one of which is as follows: Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 12 to Figure 14 As shown, the air pressure regulating assembly 5 includes a plurality of cylinders 51, an exhaust pipeline 52 and an air extraction pipeline 53; a nozzle 54 having the same width as the discharge chamber 200 is provided on the side of the upper end of the sliding chamber 101 facing the opening of the discharge chamber 200. The working ends of the plurality of cylinders 51 are connected to the sliding chamber 101 and the immersion chamber 100 through the exhaust pipeline 52 and the air extraction pipeline 53 respectively. A second rack plate 511 vertically slidably mounted on the outer slide groove 102 of the immersion tank 1 is fixed to the working end of the cylinder 51, and a vertical first rack plate 22 is extended to the outer side of the top of the discharge chamber 2. A gear 104 is also rotatably mounted on the outer side of the immersion tank 1, which meshes with the first rack plate 22 and the second rack plate 511 respectively. When the discharge box 2 moves vertically downward, the meshing of the first rack plate 22 and the gear 104 can drive the second rack plate 511 to move upward, and then the working end of the cylinder 51 can pump the gas in the immersion chamber 100 into the cylinder 51 for storage through the exhaust pipe 53. When the discharge box 2 moves vertically upward, the meshing of the first rack plate 22 and the gear 104 can drive the second rack plate 511 to move downward, and then the working end of the cylinder 51 can discharge the gas stored in the cylinder body to the sliding chamber 200 through the exhaust pipe 52.

[0047] It should be known that the specific number and installation positions of the cylinders 51 can be set according to actual needs, for example Figure 1 As shown, there are four cylinders 51, and each cylinder is provided with a narrower side corner of the immersion tank 1, and the driving end of the cylinder 51 is connected to the corresponding second rack 511 through a horizontally extending fixing plate. The two cylinders 51 located on the same side share the same exhaust pipeline 52 and exhaust pipeline 53; the nozzle 54 can dilute and slow down the airflow of the exhaust pipeline 52 and achieve range amplification.

[0048] It should also be known that the specific structure and working principle of the cylinder 51 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here. At the same time, both the exhaust pipe 52 and the exhaust pipe 53 are equipped with a one-way valve, and the one-way conduction of the one-way valve is used to perform one-way conduction work respectively, thereby realizing the extraction, storage and discharge of the gas in the immersion chamber 100.

[0049] In this embodiment, in order to ensure the immersion effect of the transformer coil 01 and facilitate loading and unloading, as Figures 1 to 3 as well as Figures 12 to 15 As shown, a loading platform 11 is horizontally arranged on one side of the top of the immersion box 1, and the transformer coils 01 to be immersed can be transported to the loading platform 11 in sequence. Multiple unloading components 4 for placing the transformer coils 01 to be immersed are installed at equal intervals in the unloading cavity 200. The unloading components 4 can be driven and cooperated with the immersion box 1, so that when the unloading box 2 carries the unloading components 4 to move to the highest position, the unloading components 4 rotate to the horizontal position toward the upper loading platform 11 through cooperation with the immersion box 1, and then the transformer coil 01 can be manually pushed to slide along the loading platform 11. The transformer coil 01 can be inserted into the unloading component 4 for loading. After the loading of the transformer coil 01 is completed, the unloading component 4 will carry the sleeved transformer coil 01 and reset it to the vertical position by moving the unloading box 2 downward and disengaging from the immersion box 1.

[0050] It should be known that if the discharge component 4 is not provided, the transformer coil 01 is directly placed in the discharge chamber 200, which may cause interference to some areas of the transformer coil 01 and affect the immersion effect. At the same time, due to the structure of the discharge chamber 200, it is inconvenient to load and unload the transformer coil 01. By providing the discharge component 4, it is possible to restrict the transformer coil 01 to a certain area, and the immersion effect of the transformer coil 01 can be guaranteed. At the same time, the position change of the discharge component 4 can facilitate the loading and unloading process of the transformer coil 01. Specifically, when loading, the discharge component 4 is in a horizontal state. At this time, there is no need to lift the transformer coil 01. It only needs to be rolled along the loading platform 11 to the corresponding position and pushed onto the corresponding discharge component 4; the unloading process is the same.

[0051] In this embodiment, there are many specific ways for the discharge assembly 4 to cooperate with the immersion tank 1 to achieve corresponding rotation. One structure is as follows: Figure 8 , Fig.12 and Fig.13As shown, a stopper 105 is provided on the top of the sliding cavity 101 near the loading platform 11; the discharge assembly 4 includes a discharge part and a support plate 41. The support plate 41 is rotatably mounted on the outside of the bottom end of the discharge cavity 200 through the first end, and the discharge part is vertically mounted on the second end of the support plate 41; one side of the first end of the support plate 41 is elastically connected to the discharge box 2 through a first torsion spring 411, and the other side of the first end of the support plate 41 is provided with a top plate 412 extending radially along the rotation direction. When the discharge box 2 slides vertically in the sliding cavity 101, as shown in FIG. Fig.13 and Fig.14 As shown, the support plate 41 drives the discharge part to be in a vertical state under the elastic force of the first torsion spring 411. When the discharge box 2 moves up to the top of the sliding cavity 101, as shown in FIG. Fig.12 As shown, the top plate 412 and the stopper 105 are pressed together to drive the support plate 41 to drive the discharge part to rotate from vertical to extending out of the discharge cavity 200 and to a horizontal state.

[0052] It should be known that the elastic coefficient of the first torsion spring 411 needs to meet the weight requirements of the discharge part itself and the transformer coil 01.

[0053] It should also be known that, during the process of the discharge part rotating from vertical to horizontal, the discharge part may generate an outward driving force on the transformer coil 01, and the inertia generated by the driving force on the transformer coil 01 will drive it to fall off from the discharge part, which may cause damage to the transformer coil 01. Therefore, when the transformer coil 01 is unloaded, it is necessary to limit the transformer coil 01 to prevent it from falling off. At the same time, during the process of the transformer coil 01 being immersed in liquid, the transformer coil 01 cannot be interfered by the limiting structure to avoid the situation where some areas are not fully immersed in liquid.

[0054] In this embodiment, there are many specific structures of the discharge part that can realize the above-mentioned limiting function, one of which is as follows: Figure 8 , Fig. 9 , Figures 11 to 15 As shown, the discharge part includes a support sleeve 42 and a limiting assembly; the support sleeve 42 is vertically mounted on the second end of the support plate 41, and the limiting assembly is mounted on the support sleeve 42. The limiting assembly is radially opened in the non-vertical state of the support sleeve 42, thereby axially limiting the transformer coil 01 sleeved on the support sleeve 42. When the support sleeve 42 is in the vertical state, the limiting assembly is retracted to release the contact with the transformer coil 01.

[0055] Specifically, there are many specific structures of the limit assembly that can be radially opened and closed, one of which is as follows: Figures 8 to 15As shown, the support sleeve 42 is provided with a plurality of axially extending open slots 420 at equal intervals along the circumferential direction; the limiting assembly includes a driving rod 44 and at least one group of limiting rods 43. The driving rod 44 is axially slidably installed at the center of the support sleeve 42, and both ends of the driving rod 44 extend to the outside of the two ends of the support sleeve 42; at the same time, the driving rod 44 is sleeved with a second spring 45 on the rod section in the support sleeve 42, and the driving rod 44 can be elastically slidably installed with the support sleeve 42 through the second spring 45. Multiple groups of limiting rods 43 are installed at intervals along the axial direction of the support sleeve 42, and the multiple limiting rods 43 of each group are correspondingly installed in the open slots 420 along the circumferential direction and cooperate with the driving rod 44. When the discharge part is vertical, the bottom end of the discharge cavity 200 can squeeze the end of the driving rod 44 outside the support sleeve 42 to drive it to move axially, and then drive the limit rod 43 to rotate along the radial plane until it is closed; at this time, the inner side of the transformer coil 01 is spaced from the support sleeve 42 and the limit rod 43, so that the inner and outer sides of the transformer coil 01 can be well immersed. When the discharge part is not vertical, the driving rod 44 will perform axial reset movement under the elastic force of the second spring 45, and then drive the limit rod 43 to rotate along the radial plane until it is open, so that the limit rod 43 can squeeze and limit the inner side of the transformer coil 01 to ensure that the transformer coil 01 can remain stable during the discharge process.

[0056] It should be known that when the discharge portion is in the horizontal loading stage, the limit rod 43 is also in an open state. At this time, the drive rod 44 can be manually pulled toward the outer end to drive the limit rod 43 to retract, thereby achieving stable loading of the transformer coil 01; of course, the limit rod 43 can also be directly squeezed by the end of the transformer coil 01 to drive it to rotate in the direction of retraction.

[0057] It should also be known that when the limiting rod 43 is in the open limiting state, the limiting rod 43 is in an inclined state, and the inclined direction is toward the end of the driving rod 44 close to the support plate 41. That is, when the transformer coil 01 and the limiting rod 43 are in an extruded state, if the transformer coil 01 has a tendency to detach outward, the extrusion force of the transformer coil 01 on the limiting rod 43 will drive the limiting rod 43 to move in the direction of increasing the radial extension size, thereby increasing the limiting capacity of the transformer coil 01.

[0058] It is understandable that the number of groups of limiting rods 43 and the specific number of limiting rods 43 included in each group can be set according to actual needs. For example, Figure 8 and Fig. 9 As shown, there are two groups of limiting rods 43, each group includes three limiting rods 43, and correspondingly, three opening slots 42 are also provided.

[0059] In this embodiment, there are various specific structures in which the driving rod 44 drives the limiting rod 43 to rotate by axial movement, including but not limited to the following two.

[0060] The first type: Figures 9 to 11 As shown, the opening groove 420 is fixedly provided with a guide rod 4201; the limiting rod 43 is hinged with the driving rod 44 through the end, and the side of the limiting rod 43 close to the driving rod 44 is provided with a guide groove 430 that slides with the guide rod 4201; when the driving rod 44 moves axially, the guide rod 4201 slides relative to the guide groove 430 to drive the limiting rod 43 to open or close relative to the support sleeve 42.

[0061] The second type: the limit rod 43 is elastically rotatably installed in the opening groove 420, and the end of the limit rod 43 extending into the support sleeve 42 is abutted against the driving rod 44, and then the driving rod 44 is abutted and squeezed during the movement to drive the limit rod 43 to rotate around the installation position to open, and when closing, the limit rod 43 is reset under the action of elastic force by the distance of the driving rod 44.

[0062] It should be known that both of the above-mentioned situations can meet the requirements of this application, and in this embodiment, the first specific structure mentioned above is preferably adopted.

[0063] It should also be known that when the discharge portion is in a vertical position, the transformer coil 01 will abut against the support plate 41 through the lower end under the action of gravity, and the abutting contact portion of the transformer coil 01 may affect the penetration of the paint liquid. In order to ensure the immersion effect of the transformer coil 01, the transformer coil 01 can be displaced relative to the support plate 41 during the immersion, so that the blocked portion of the transformer coil 01 is brought into contact with the paint liquid again.

[0064] In this embodiment, there are many ways to achieve the above functions, one of which is as follows: Figure 3 , Figure 4 , Figure 8 , Fig.15 and Fig.16 As shown, the discharge part and the support plate 41 are elastically rotatably mounted by the second torsion spring 423. Specifically, the support sleeve 42 and the support plate 41 are elastically rotatably mounted by the second torsion spring 423. A radially extending support frame 421 is provided on the side of the support sleeve 42 close to the support plate 41, and the transformer coil 01 can be supported on the support frame 421 when it is vertical. A traction assembly 23 is provided at the bottom end of the discharge chamber 200. The traction assembly 23 is driven and matched with the immersion tank 1 and the support sleeve 42 respectively, so that when the discharge box 2 enters the immersion chamber 100, the immersion tank 1 drives the traction assembly 23 to drive the support frame 421 to deflect relative to the transformer coil 01.

[0065] Specifically, Figure 4 , Figure 7 , Figure 8 , Fig.15 and Fig.16 As shown, a second abutment plate 422 is provided on the support frame 421, and a traction plate 103 is vertically fixed in the immersion chamber 100 of the immersion box 1, and a wavy side edge is provided on one side of the traction plate 103. The traction assembly 23 includes a traction rod 231 and a first spring 232; the traction rod 231 is elastically slidably installed at the bottom end of the discharge chamber 200 through the first spring 232, and a first abutment plate 2311 is provided on the traction rod 231. When the discharge box 2 moves downward in the immersion chamber 100, the traction rod 231 cooperates with the wavy edge of the traction plate 103 through the end under the elastic force of the first spring 232 to slide back and forth, and then the first abutment plate 2311 and the second abutment plate 422 are squeezed to drive the support frame 421 to continuously deflect back and forth relative to the transformer coil 01.

[0066] It should be known that the squeezing of the first abutment plate 2311 and the second abutment plate 422 can drive the support frame 421 to deflect in one direction relative to the transformer coil 01, and then the support frame 421 is reset and deflected again under the elastic force of the second torsion spring 423 to achieve reciprocating deflection.

[0067] It should also be known that the paint liquid has a certain viscosity. When the support frame 421 rotates, the viscosity of the paint liquid will hinder the synchronous rotation of the transformer coil 01, thereby causing relative deflection and misalignment between the support frame 421 and the transformer coil 01.

[0068] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
