Description

Technical Field

[0001] The utility model relates to the field of curing furnaces, in particular to a curing furnace for a composite enclosure of transformer insulating materials. Background Art

[0002] Curing refers to the production process of heating parts, curing resin, and drying in the electronics industry and other various industries to enhance the stress of material bonding. In the production and processing of transformer insulating materials, the transformer insulating materials are used for curing treatment to increase the stress of the bond between the transformer insulating materials and parts, meeting the production requirements of the transformer insulating materials. After retrieval, in the prior art (publication number: CN202321752229.1), a curing furnace for transformer production is disclosed. It is described in the text that "by means of the threaded top covers that are thread-adjusted inside one ends of the first storage rack, the second storage rack, and the third storage rack, when the parts of the transformer need to be taken out of the device, first hold the pull handle outside the threaded top cover, then pull out the first storage rack, the second storage rack, and the third storage rack from the inside of the curing furnace body, then rotate the threaded top covers to open the first storage rack, the second storage rack, and the third storage rack, and then pour out the parts inside. Thus, the convenience of taking out the transformer parts of the device is improved." However, in the prior art, during the process of extracting the storage rack, the storage rack and the transformer parts are at a relatively high temperature, and manual pouring is likely to cause potential safety hazards. Content of the Utility Model

[0003] To overcome the defects existing in the prior art, a curing furnace for a composite enclosure of transformer insulating materials is provided herein to solve the problem that during the process of extracting the storage rack in the prior art, the storage rack and the transformer parts are at a relatively high temperature, and manual pouring is likely to cause potential safety hazards.

[0004] To achieve the above object, a curing furnace for a composite enclosure of transformer insulating materials is provided, including: a transformer curing furnace body and a curing frame, wherein the curing frame is inserted inside the transformer curing furnace body.

[0005] A sealing enclosure is fixedly locked on the front surface of the transformer curing furnace body. A top protective cover is screwed and installed on the upper surface of the sealing enclosure. A protective side cover is screwed and fixed on the front surface of the sealing enclosure. An explosion-proof outer layer is arranged on the outer surface of the sealing enclosure. The explosion-proof outer layer is internally wrapped with a heat-insulating rock wool board and a fire-proof board. The front and rear side surfaces of the heat-insulating rock wool board are both attached with fire-proof boards. The curing frame is welded on the rear side surface of the sealing enclosure.

[0006] Further, an electric control box is arranged at the left end of the transformer curing furnace body. An alarm is installed on the upper surface of the electric control box. A handle is welded on the front surface of the sealing enclosure.

[0007] Furthermore, the explosion-proof outer layer, heat-insulating rock wool board, and fireproof board form a composite sealing enclosure, and the curing frame is fixedly arranged in an inclined state at the rear side of the sealing enclosure.

[0008] Furthermore, rollers are installed on the lower end surface of the sealing enclosure, and the protective side covers are symmetrically fixed at the left and right side edges of the front surface of the sealing enclosure.

[0009] Furthermore, a limiting plate is welded to the rear side surface of the curing frame, a plugging hole is formed on the rear surface of the limiting plate, and ventilation grooves are formed on the left and right side walls of the curing frame.

[0010] Furthermore, a breathable mesh plate is welded to the inner side of the lower frame surface of the curing frame, and convex curved spacer blocks are welded equidistantly on the upper surface of the breathable mesh plate.

[0011] Furthermore, the sealing enclosure, protective side covers, top protective cover, and curing frame constitute a protective material-taking mechanism of the transformer curing furnace.

[0012] The beneficial effects of the present utility model are as follows. The transformer insulation material composite enclosure curing furnace of the present utility model connects the sealing enclosure with the curing frame inside the sealing enclosure. By pulling the sealing enclosure outwards, the curing frame is taken out of the furnace, so that the transformer insulation parts placed on the mesh surface of the curing frame are moved to the external environment for cooling. The protective side covers and top protective cover installed on the outer side of the sealing enclosure are convenient for effectively preventing the high-temperature gas in the furnace from blowing towards the material-taking personnel, avoiding the material-taking personnel from being scalded by the high-temperature gas or contacting the high-temperature parts. At the same time, the explosion-proof outer layer, heat-insulating rock wool board, and fireproof board of the sealing enclosure form a multi-layer composite structure, which is convenient for protecting the staff at the outer side surface of the sealing enclosure, strengthening the protection effect of the transformer curing furnace, and improving the safety performance of the special transformer curing furnace.
