Technical Field

[0001] The utility model relates to the technical field of epoxy resin degassing, in particular to a degassing device for high-viscosity modified epoxy resin. Background Art

[0002] Epoxy resin is a polymer material widely used in coatings, adhesives, electronics, building materials and other fields. It is composed of epoxy groups and curing agents and has excellent mechanical properties, chemical resistance, electrical properties and heat resistance. Currently, high-viscosity modified epoxy resins need to be degassed before use to achieve better results.

[0003] After searching, the Chinese patent authorization number is CN 213853232 U, which discloses a degassing device for high viscosity modified epoxy resin, and relates to the technical field of degassing of high viscosity modified epoxy resin. A discharge pipe is installed at the lower end of the main tank, and the discharge pipe is welded to the main tank. A filling pipe is installed on one side of the upper end of the main tank, and the filling pipe is welded to the main tank. A second control valve is installed outside the filling pipe, and a first control valve is installed outside the discharge pipe. A sealing box is installed outside the discharge pipe and the filling pipe, and the sealing box is welded to the discharge pipe and the filling pipe. A sealing cover is installed at one end of the sealing box away from the main tank, and one end of the sealing cover is connected to the sealing box through a connecting shaft.

[0026] The active rod 5 penetrates through the degassing tank 1 and is rotatably connected to the degassing tank 1 , and a circular sliding groove is provided on the surface of the active rod 5 close to the driven rod 6 .

[0027] An L-shaped plate 14 is slidably connected in the circular slide groove of the active rod 5, and a protective cover 15 is fixedly connected to the bottom of the L-shaped plate 14. The active rod 5 passes through the protective cover 15 and is rotatably connected to the protective cover 15. The protective cover 15 can be supported by the L-shaped plate 14. When the active rod 5 rotates, the protective cover 15 will not rotate. At the same time, the outer surface of the protective cover 15 is a curved surface, which does not affect the feeding of epoxy resin. The protective cover 15 can also prevent the epoxy resin from affecting the rotation of the elliptical plate 7.

[0028] The fixing plate 8 is fixedly connected to the inner wall of the protective cover 15 , the elliptical plate 7 is slidably connected to the inclined plate 11 , and the push rod 9 passes through the fixing plate 8 and is slidably connected to the fixing plate 8 .
