[0003] When a vacuum epoxy resin pouring device is used to pour a dry-type transformer, the fluid epoxy resin is gradually injected into the dry-type transformer through a hose in a vacuum environment. When the amount of epoxy resin injected inside the dry-type transformer reaches an appropriate level, the hose for conveying the epoxy resin can be taken out of the dry-type transformer. Although the taken-out hose has stopped conveying the epoxy resin, some epoxy resin still remains on its surface. The epoxy resin remaining on the surface of the hose is easy to drip onto the inside of the vacuum epoxy resin pouring device, and is easy to gradually solidify on the hose and the inside of the epoxy resin pouring device over time. Therefore, a dry-type transformer epoxy resin pouring device is proposed to address the above problems. Utility Model Content

[0025] As a further implementation of this solution, the number of hook racks 21, the number of immersion tubes 222 and the number of hoses 61 are the same, and the hook racks 21 are equidistantly distributed on the same horizontal plane inside the device bin 2, so that each hose 61 has a position for placement and cleaning;
[0026] As a further implementation of the present invention, a groove is provided inside the hook frame 21, and the groove inside the hook frame 21 is engaged with the hose 61 to prevent the hose 61 from hanging in the device bin 2;
[0027] As a further implementation of the present invention, the hook frame 21, the soaking tube 222 and the hose 61 are on the same vertical plane, the hose 61 slides inside the soaking tube 222, and the soaking tube 222 and the drainage tube 223 are connected to each other, so that the water used to clean the hose 61 has a certain fluidity in the soaking tube 222 and the drainage tube 223;
[0028] As a further implementation of this solution, the drainage pipe 223 is parallel to the tank box 22, and one end of the drainage pipe 223 is provided with the first valve 224 close to the chamber door 3, so as to collect and process the cleaning water of the epoxy resin on the cleaning and differentiation hose 61;
[0029] As a further implementation of this solution, the overflow pipe 221 is arranged on the side of the first valve 224 close to the door 3, and the overflow pipe 221 and the water inlet pipe 225 are respectively arranged on both sides of the tank box 22, which can prevent the cleaning water in the tank box 22 from leaking along the side of the tank box 22;

[0031] Working process: After using the dry-type transformer epoxy resin pouring device to pour the dry-type transformer, it is necessary to remove the hose 61 used to transport the epoxy resin from the dry-type transformer. At this time, part of the epoxy resin is attached to the inner and outer walls of the hose 61, and then the hose 61 can be inserted into the immersion tube 222 fixedly connected to the tank box 22, and the hose 61 is clamped in the hook frame 21 fixedly connected to the inner side of the device bin 2. Through the restriction of the hook frame 21, the hose 61 is closely attached to the inner wall of the device bin 2 to a large extent, preventing the hose 61 from being suspended in the device bin 2, and ensuring that the outlet end of the hose 61 is stably placed in the immersion tube 222. After the hose 61 is placed, the second valve 226 arranged in the water inlet pipe 225 is opened, and cleaning water is transported to the tank box 22 through the water inlet pipe 225. Since the tank box 22 is connected to the drain pipe 223 through a plurality of immersion pipes 222, and the drain pipe 2 The first valve 224 arranged on the inner side of 23 is in a closed state, and the cleaning water that decomposes the epoxy resin on the hose 61 can be stored in the tank box 22 until the water surface line of the cleaning water in the tank box 22 reaches the position of the overflow pipe 221 fixedly connected to the tank box 22, and part of the cleaning water can enter the drain pipe 223 through the overflow pipe 221 and be discharged through the drain pipe 223. The overflow pipe 221 can effectively prevent a large amount of cleaning water from leaking along the edge of the tank box 22. When the first valve 224 arranged in the drain pipe 223 is closed, the cleaning water in the soaking pipe 222 causes the epoxy resin on the hose 61 to gradually detach and decompose in the cleaning water, so that after opening the first valve 224, the cleaning water carrying the epoxy resin can be discharged from the drain pipe 223, so that the operator can collect and process it as a whole, effectively preventing the epoxy resin attached to the inner side of the hose 61 from dripping onto the inner side of the epoxy resin casting device.
