Super strength high molecule fibre intelligent high temperature thermo-setting machine

Abstract

The invention discloses an intelligent high temperature thermal shaping machine for ultra intense polymer fiber. The machine comprises an electrical heater, thermoscopes, an electric control device, a shell, and adjustable feet, and further comprises an inner cavity body, a left end expansion joint, a right end expansion joint, a left end seal, a right end seal and a port sealing device. Inner holes of the left end expansion joint and the right expansion joint are internally and respectively penetrated and covered by the two ends of the inner cavity body, and the two ends can move in the inner holes. The electrical heater has flat shaped structure and is longitudinally arranged on the upper surface and the lower surface of the inner cavity body and transversely arranged on the two side faces of the inner cavity. The thermoscopes are arranges above the inner cavity body along the width direction in two lines; probes of one line of the thermoscopes are inserted into the inner cavity body, and the probes of the other line are contacted with the surface of the inner cavity body. Insulation cotton is filled into the space between the inner cavity body and the external side board arranged on a machine frame. The machine can meet the technique requirement of high temperature thermal shaping for tow in the production process of aramid and save energy.

Description

technical field [0001] The invention relates to heat-setting equipment for high-molecular fibers in the chemical fiber industry, in particular to an intelligent high-temperature heat-setting machine for ultra-strong high-molecular fibers. Background technique [0002] At present, the development of high-performance fibers is becoming more and more rapid, and the applications are becoming more and more popular, and the impact on the national economy is becoming more and more significant. As a representative of super-strong polymer fibers, aramid has become an important raw material for advanced protective materials and structural materials due to its excellent heat resistance and flame retardancy, electrical insulation and good textile performance. In the process of producing aromatic wheels, high temperature heat setting of tow is one of the important processes. The temperature of high-temperature heat setting of tow usually reaches 450°C, and at the same time, the requirem...

AI Technical Summary

Problems solved by technology

At present, the sizing equipment using circular electric heating tubes can meet the temperature requirements of the aromatic wheel tow for heat setting, but the circulating air produced by the heat circulation fan in the box will blow the tow away, and at the same time, the heat in the box can Leakage from the entrance and exit of the tow, resulting in a large temperature difference between the front and rear sides of the box and the temperature in the middle, so it cannot meet the requirements for high-temperature heat-setting of aramid tow

In addition, because the circular electric heating tube is in line contact with the box wall, the thermal efficiency is poor and energy is wasted
