High-temperature heat setting device

Abstract

The invention provides a high-temperature heat setting device which comprises a box, a heating device and an adjusting device, wherein the box comprises an upper shell, a lower shell and an inner cavity, the lower shell is opposite to the upper shell, the inner cavity is defined by the upper shell and the lower shell, and the inner cavity comprises an upper cavity arranged in the upper shell and a lower cavity arranged in the lower shell; the heating device comprises a first heating device arranged in the upper cavity and a second heating device arranged in the lower cavity; and the adjusting device is arranged on the upper shell and connected with the first heating device, and used for adjusting the first heating device to move relative to the vertical direction of the upper shell. According to the high-temperature heat setting device disclosed by the invention, the adjusting device is arranged and is connected to the first heating device arranged in the upper cavity, and the relative position of the first heating device and the upper shell is regulated by the adjusting device, the size of a heating cavity defined by the first heating device and the second heating device is changed, thereby reaching the purpose of adjusting the heating cavity.

Description

technical field [0001] The invention relates to the field of chemical fiber processing, in particular to a high-temperature heat-setting equipment. Background technique [0002] High-performance fibers and fabrics are becoming more and more popular in all walks of life. Because of their excellent properties such as high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight, they are widely used in the production of high-performance tire cords, Powerful conveyor belts, bulletproof clothing, helmets, wings or rocket engine casings, pressure vessels, ropes and fiber composite materials are becoming more and more prominent in the national economy. [0003] For high-performance fibers or fabrics, heat setting is the core technology to improve their mechanical properties and stability. During the setting process, the temperature of the heat setting box is as high as 400-500°C. At the same time, the temperature uniformity of the heat set...

AI Technical Summary

Problems solved by technology

Conventional steam heating, although the temperature control accuracy is high, the maximum temperature generally does not exceed 200 ° C, which cannot meet the heat setting process requirements of fibers and fabrics

However, the traditional electric heating heat setting equipment can reach a higher heat setting temperature, but the uniformity of temperature distribution in the working cavity is not good, and it is inconvenient to maintain and overhaul. At the same time, the size of the working cavity surrounded by the heater cannot Adjustment, so that the heat setting box cannot be adjusted according to the size of the heated object, and the scope of application is narrow

In addition, fibers and fabrics are easily oxidized at high temperatures, which cannot meet the requirements of high-temperature heat-setting processes
