Abstract

The invention discloses a continuous preheating and drying device for a PVC-O pipe fitting. The device comprises a drying box body, a pipe fitting fixing mechanism located in the drying box body and used for fixing the pipe fitting, and a heating mechanism located in the drying box body and used for preheating and drying the pipe fitting. The heating mechanism comprises a heating rod arranged in the pipe fitting fixing mechanism in a matched mode, a sealing sleeve arranged on the periphery of the heating rod in a sleeving mode, and a convection draught fan arranged on the side face of the interior of the drying box body; and the convection draught fan corresponds to the pipe fitting fixing mechanism. The continuous preheating and drying device for the PVC-O pipe fitting is reliable in structure, good in preheating and drying effect and excellent in use performance; the pipe fitting is reliably fixed through the pipe fitting fixing mechanism, and the pipe fitting is preheated and dried through wind power generated by the heating rod in the heating mechanism and the convection draught fan in the drying box body; and heat can surround and cover the outer wall of the pipe fitting for a long time through the temperature retention effect of the sealing sleeve, so that the drying effect on the pipe fitting is improved, and the forming quality of the pipe fitting is guaranteed.

Description

technical field [0001] The invention relates to the technical field of material preparation, in particular to a continuous preheating and drying device for PVC-O pipe fittings. Background technique [0002] PVC-O pipe rearranges the molecules of the material through bidirectional stretching at the glass transition temperature of the PVC material, so that the material (pipe wall) forms a network structure, which can withstand micro cracks originating from the material body or scratches on the surface of the pipe wall. The brittle failure of the cracks significantly improves the strength, toughness and crack resistance of the pipe. Biaxially oriented polyvinyl chloride (PVC-O) pipe is a pipe manufactured through a special orientation process. This process is to stretch the PVC-U pipe produced by the extrusion method axially and radially. The PVC long-chain molecules in the pipe are regularly arranged in the biaxial direction, and a new type of PVC pipe with high strength, hig...
