Mixer for lining resin of glass reinforced plastic pipe and catalyst

The invention discloses a mixer for lining resin of a glass reinforced plastic pipe and a catalyst. The mixer comprises a duct. One end of the duct is provided with three inlets, and the other end of the duct is transversely provided with a discharging pipe. Discharging holes are formed along one side of the discharging pipe longitudinally and evenly. A guiding shaft is arranged in the middle of the duct. Guiding disks are arranged on the guiding shaft longitudinally and evenly. Guiding holes are formed in the end face, close to the peripheral part, of each guiding disk. The guiding holes in every two adjacent guiding disks are staggered with one another. The duct is formed by connecting a branching pipe A, a branching pipe B and a branching pipe C in a threaded mode in the axial direction. A positioning disk is arranged on one end face of the branching pipe C. Guiding holes are formed in the end face, close to the peripheral part, of the positioning disk. A positioning hole is formed in the center of the positioning disk, and one end of the guiding shaft is fixed in the positioning hole. Spacing sleeves are evenly arranged on the guiding shaft in the axial direction and located between the guiding disks. According to the mixer, the resin and the catalyst can be fully mixed, and the resin is completely cured in the follow-up process, so that the quality of products is ensured.
