Technical Field
[0001] This utility model relates to the field of insulating impregnation varnish production technology, specifically to a dilution device for insulating impregnation varnish production. Background Technology
[0002] Insulating varnish is one of the three main insulating materials for winding insulation of electrical products. Through the impregnation process, the insulating varnish penetrates and fills the gaps and pores of coils, wire grooves or other insulators. Then, after curing, it bonds the coil wires into an insulating whole and forms a continuous insulating layer on its surface, improving dielectric properties, mechanical properties, thermal conductivity and protective properties.
[0003] A dilution device for producing insulating impregnating varnish is a commonly used device in the production of insulating impregnating varnish. However, existing dilution devices still have shortcomings. Most existing dilution devices directly transport the diluent medium into the dilution device through a conveying pipe. However, it is difficult to uniformly add the diluent medium during the conveying process, which makes it difficult to achieve uniform dilution during mixing and stirring. This greatly increases the dilution time of the device and further reduces the dilution efficiency, thus affecting the operation by the staff. Utility Model Content

[0011] This utility model provides a dilution device for producing insulating impregnation varnish, which has the following beneficial effects:
[0012] 1. This dilution device for producing insulating impregnating varnish, through the arrangement of a dilution tank, a stirring device, a water pump, a first ring rod, a second ring rod, a gear block, and gears, allows the operator to simply start the water pump to transport the medium from the storage tank to the stirring device via a water pipe and spray it out through the nozzle when dilution of the insulating impregnating varnish in the dilution tank is required.

Therefore, they have no substantial technical significance.

[0023] Please see Figures 1 to 7This utility model provides a technical solution: a dilution device for producing insulating impregnation varnish, including a base 1, a dilution tank 2 fixedly connected to the upper surface of the base 1, a stirring device 3 inside the dilution tank 2, a storage cylinder 4 fixedly connected to the upper surface of the base 1 near the dilution tank 2 corresponding to the stirring device 3, a water pump 5 fixedly connected to the top of the storage cylinder 4, a water inlet pipe 6 fixedly connected to the water inlet of the water pump 5, a water outlet pipe 7 fixedly connected to the water outlet pipe 7, a connecting pipe fixedly connected to the other end of the water outlet pipe 7, and the bottom of the connecting pipe fixedly connected to the top of the dilution tank 2. When it is necessary to dilute the insulating impregnation varnish in the dilution tank 2, the operator only needs to start the water pump 5 to transport the medium in the storage cylinder 4 to the stirring device 3 through the water outlet pipe 7 and spray it out through the spray nozzle 15. At the same time as starting the water pump 5, the motor 32 is started, so that the motor 32 drives the stirring device 3 to stir and mix the sprayed dilution medium with the insulating impregnation varnish in the dilution tank, thereby effectively improving the dilution time of the device, further improving the dilution efficiency of the device, and making the dilution medium more uniformly diluted.
[0024] Four support legs arranged in a rectangular array are fixedly connected to the four corners of the lower surface of the base 1. Correspondingly, observation windows are opened on the surfaces of the dilution tank 2 and the storage cylinder 4. The bottom end of the water inlet pipe 6 passes through the storage cylinder 4 and extends into the interior of the storage cylinder 4, and there is still a distance between the water inlet pipe 6 and the inner bottom wall of the storage cylinder 4.
[0025] The stirring device 3 includes a rotating rod 31 rotatably connected to the middle of the bottom wall of the dilution tank 2 via a rotating shaft. A motor 32 is fixedly connected to the middle of the lower surface of the base 1 corresponding to the rotating rod 31. The output end of the motor 32 passes through the base 1 and is connected to the rotating rod 31. Three evenly spaced first cross brackets 33 are fixedly connected to the surface of the rotating rod 31. A first ring rod 8 is fixedly connected to the end of the first cross bracket 33 away from the rotating rod 31. Multiple evenly spaced spray rods 34 are fixedly connected to the upper surface of the first cross bracket 33. When it is necessary to stir and mix the dilution medium in the dilution tank 2, the operator only needs to start the motor 32, so that the output end of the motor 32 drives the rotating rod 31 to rotate. In turn, the first cross brackets 33 fixedly connected to the surface of the rotating rod 31 drive the spray rods 34 to rotate and stir the dilution tank 2, thereby effectively improving the stirring efficiency of the device.
[0026] The top of the rotating rod 31 is rotatably connected to the top of the dilution tank 2 via a bearing. Slide grooves 35 are provided on the inner wall of the dilution tank 2 at locations corresponding to the first cross brackets 33. The first ring rod 8 is slidably connected to the dilution tank 2 via the slide grooves 35. Second cross brackets 36 are rotatably connected to the surface of the rotating rod 31 near the three first cross brackets 33 via bearings. Multiple evenly spaced stirring rods 37 are fixedly connected to the lower surface of the second cross brackets 36. A second ring rod 9 is fixedly connected to the end of the second cross bracket 36 away from the rotating rod 31. When the motor 32 is started, it drives the first cross brackets 33 via the rotating rod 31. While rotating with the external first ring rod 8, the toothed block 11 on the lower surface of the first ring rod 8 drives the gear 10 rotatably connected in the slide groove 35 to rotate, so that the gear 10 drives the second ring rod 9 to rotate through the toothed block 11 meshing with it, thereby driving the second cross bracket 36 and the stirring rod 37 fixed on its surface to rotate. The direction of rotation of the second cross bracket 36 is opposite to the direction of rotation of the first cross bracket 33, which further improves the stirring efficiency of the device, thereby effectively accelerating the dilution time of the device and effectively improving the practicality and applicability of the device.
[0027] The second ring rod 9 is slidably connected to the dilution tank 2 via a slide groove 35. The inner bottom wall of the slide groove 35 is rotatably connected to a gear 10 via a bearing. Several uniformly spaced tooth blocks 11 are fixedly connected to the lower surface of the first ring rod 8 and the upper surface of the second ring rod 9. The first ring rod 8 and the second ring rod 9 mesh with the gear 10 first through the tooth blocks 11.
[0028] The rotating rod 31 has a connecting groove 12 that communicates with the connecting pipe inside. The rotating rod 31 has multiple through holes 13 on its surface corresponding to the first cross bracket 33. The first cross bracket 33 has a water delivery groove 14 that matches the through holes 13 inside. The spraying rod 34 has several evenly spaced spray holes 15 on its surface. When it is necessary to add diluent to the dilution tank 2, the operator first uses the water pump 5 to transport the diluent in the storage cylinder 4 to the connecting groove 12 inside the rotating rod 31 through the water delivery pipe 7, and then transports it to the water delivery groove 14 inside the first cross bracket 33 through the through holes 13 on the surface of the rotating rod 31. Finally, it is sprayed out through the spray holes 15 that communicate with the water delivery groove 14. This allows the diluent to be transported to the dilution tank 2 for stirring at the same time as the stirring device 3 stirs the insulating varnish, effectively improving the practicality and applicability of the device.
