Description

Technical Field

[0001] The utility model relates to the technical field of oil-immersed transformers, in particular to a drying device for oil duct curtains. Background Art

[0002] In recent years, my country's power construction has developed rapidly, along with the rapid pace of grid construction. The organization of power sources is constantly adjusting, resulting in an increasing demand for transformers and stricter quality standards. The high and low voltage coils of distribution transformers are typically cylindrical. To dissipate heat, oil channels are required along the coil axis. Traditionally, these channels are constructed from corrugated cardboard. Due to its low strength, corrugated cardboard can be easily flattened during coil winding, resulting in reduced oil flow and poor heat dissipation. Using larger corrugated cardboard increases the oil channel size, which in turn increases the coil diameter and costs. Currently, curtain-style oil channels are commonly used. These channels are formed by attaching multiple stays to two parallel white cloth sheets to form a curtain-like pattern, which is then wound into a cylinder, and the coil is then wrapped around it. Alternatively, multiple stays are attached to a sheet of adhesive-dot paper to form a curtain-like pattern, which is then wound into a cylinder, and the coil is then wrapped around it.

[0003] During the production process of oil duct curtains, after using glue to stick the stays on the white cloth or glue-dot paper, it is necessary to let it stand for a while to allow the glue to dry, or place the white cloth with the stays in a drying device for drying. However, this method requires manual transfer, which is very inconvenient. Utility Model Content

[0032] Please refer to Figure 1-Figure 3 , a drying device for oil duct curtains, comprising a bracket 1, wherein the bracket 1 has a conveyor belt passing above the bracket 1;

[0033] The bracket 1 is provided with a drying cover 2, and the drying cover 2 is provided with an entrance and an exit along the moving direction of the conveyor belt;

[0034] A drying space 3 is formed between the drying cover 2 and the conveyor belt;

[0035] The drying outer cover 2 is provided with a heater, which delivers warm air into the drying space 3 .

[0036] In this embodiment, the conveyor belt conveys the support bar 12 and the white cloth 11 / dot paper 13 pressed by the automatic pressing mechanism to the drying device. Figure 4 , is a solution in which multiple stays 12 are glued to two parallel white cloths 11; please refer to Figure 5 , is a solution in which multiple stays 12 are adhered to adhesive paper 13; when multiple stays 12 are adhered to white cloth 11 or adhesive paper 13 and pressed by a pressing mechanism, there is still some glue left between the stays 12 and the white cloth 11 or between the stays 12 and adhesive paper 13. Therefore, the stays 12 and the white cloth 11 or between the stays 12 and adhesive paper 13, which have been pressed by the pressing mechanism, are conveyed from the entrance of the drying device into the drying space 3 via a conveyor belt. The warm air generated by the heater in the drying space 3 quickly dries the remaining glue between the stays 12 and the white cloth 11 or between the stays 12 and adhesive paper 13, and finally exits from the exit of the drying housing 2. This drying device is part of the fully automatic production of oil duct curtains and can quickly dry the remaining glue between the stays 12 and the white cloth 11 or between the stays 12 and adhesive paper 13. The drying device has a simple structure and can quickly dry the oil duct curtain.

[0037] Furthermore, the bracket 1 is provided with an auxiliary component for supporting and positioning the conveyor belt;

[0038] The auxiliary assembly includes a pair of support plates 5, a support rod 6 and a limiting wheel 7;

[0039] A pair of support plates 5 are installed at both ends of the bracket 1;

[0040] The support rod 6 is installed between a pair of support plates 5;

[0041] The limiting wheel 7 is installed on the supporting rod 6 , and the limiting wheel 7 is in contact with the conveyor belt. The limiting wheel 7 is used to support and position the conveyor belt.

[0042] In this embodiment, since the conveyor belt is very long, it is necessary to support and position the conveyor belt in the area of ​​the drying device; it is stuck in the positioning key of the conveyor belt through the limiting wheel 7, which not only supports the conveyor belt, but also prevents the conveyor belt from running off the track.

[0043] Furthermore, the drying cover 2 is hinged to the support plate 5 via a hinge 8 .

[0044] In this embodiment, the drying cover 2 is hinged on the support plate 5, and the drying cover 2 can be opened at any time to check the product, for example, to check whether the product is pressed well or to check whether the support bar 12 is well pasted to the glue paper 13 or the white cloth 11.

[0045] Furthermore, the heater includes a first heater 9 and a second heater 10;

[0046] The first air heater 9 is located directly above one of the moving paths of the white cloth 11;

[0047] The second air heater 10 is located directly above another moving path of the white cloth 11 .

[0048] In this embodiment, since there are two parallel white cloths 11, and the glue is located at the contact surface between the white cloths 11 and the support bars 12, the first air heater 9 can supply hot air to one of the white cloths 11, and the second air heater 10 can supply hot air to the other white cloth 11, which has a better drying effect. In addition, in this embodiment, two first air heaters 9 and two second air heaters 10 are provided. It should be noted that if the solution of glue-dotting paper 13 and support bars 12 is adopted, since the contact surface between the glue-dotting paper 13 and the support bars 12 is large, it is not necessary to glue the entire contact surface. It is only necessary to glue the two ends of the contact surface separately. The glue-dotting positions are: one is directly below the first air heater 9, and the other is directly below the second air heater 10.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
