Steel wire mesh skeleton plastic composite tube constant-temperature heating device and application method thereof

Abstract

The invention relates to the field of plastic tube processing, and concretely relates to a steel wire mesh skeleton plastic composite tube constant-temperature heating device and an application methodthereof. The heating device comprises two heating mechanisms arranged at the middle and the outlet end of the heating device, every heating mechanism comprises a heating tube, a heat insulation layerand a stainless steel shell which are sequentially arranged from inside to outside, every heating mechanism is provided with a temperature detector for detecting the temperature of a tube, the heating mechanisms are provided with a controller, and the controller is electrically connected with the heating tubes and the temperature detectors. The heating device is composed of the inner heating tubes, the middle heat insulation layers, the outer stainless steel shells and the temperature detectors. The infrared heating tubes are arranged at the inner layer of the heating device, and the lines ofthe heating tubes are connected at intervals. The outer layer of the heating device is composed of an air return fan and relevant connecting pipelines.

Description

technical field [0001] The invention relates to the field of plastic pipe processing, in particular to a constant-temperature heating device for plastic composite pipes with a steel mesh skeleton and an application method thereof. Background technique [0002] In the current plastic pipe manufacturing industry, the inner layer of steel mesh skeleton plastic composite pipe is a plastic layer, the middle layer is glue and steel mesh layer, and the outer layer is a plastic layer. In order to realize the bonding of plastic and steel wire, a heating process is required during production. . The effect of heating has a certain influence on the peel strength of the pipe. The ambient temperature difference between day and night during production is large, resulting in a certain difference in the peel strength of the pipe produced at different times. A steel mesh skeleton plastic composite pipe heating equipment with constant and adjustable heating effect has become a demand in the p...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a constant temperature heating equipment for steel mesh skeleton plastic composite pipes, through setting, to provide a kind of heating temperature and pipe temperature correlation, heating temperature can be adjusted in real time, heat energy recovery and energy saving effect is good Wire mesh skeleton plastic composite pipe constant temperature heating equipment; in addition, it consists of two sets of the same heating mechanism, one is used for pipe preheating, and the other is used for process constant heating, to solve the large difference in ambient temperature between day and night during production, resulting in different There is a certain difference in the peel strength of the pipes produced over time
