Embodiment Construction

[0032] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] The high-temperature heat-setting equipment according to the embodiment of the present invention includes: a box body, a frame 20 and a heating device. The length of the constant temperature zone of the box body of the high temperature heat setting equipment provided by the present invention is 2000mm to 3000mm. The width of the constant temperature zone is according to the formula W=n (w x +10) +20, where W is the width of the constant temperature zone of the box, in mm, w x is the width of fibers or fabrics, in mm, and n is the number of fibers or fabrics, and the numerical units represented by the above letters are millimeters. Preferably, the constant temperature zone in this embo...

Abstract

The invention provides a high-temperature heat setting device. The high-temperature heat setting device comprises a box body, frames and heating devices. The box body comprises an upper casing body, a lower casing body and inner cavity bodies, wherein the inner cavity bodies comprise an upper cavity body arranged on the upper casing body and a lower cavity body arranged on the lower casing body. The frames comprise a first frame arranged on the upper cavity body and a second frame arranged on the lower cavity body, wherein the first frame body and the second frame body are correspondingly arranged. The heating devices comprise a first heating device arranged inside the first frame body and a second heating device arranged inside the second frame body, and both the first heating device and the second heating device comprise a plurality of plate-type heaters which are sequentially arranged in the length direction of the frames. According to the technical scheme of the high-temperature heat setting device, the heating devices are divided into the plurality of plate-type heaters to enlarge contact areas, improve heating efficiency and heating speed, reduce energy consumption and improve the uniformity degree of the temperature distribution of the box body, and the box body is of a frame type structure so that heat deformation of the box body due to long-time operation under high temperatures can be effectively avoided.

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 have excellent properties such as high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. They are widely used in various fields of the national economy and have an irreplaceable position for other traditional fibers. It is widely used in strong conveyor belts, bulletproof clothing, helmets, wings or rocket engine casings, pressure vessels, ropes and fiber composites. [0003] Heat setting is a key technology to improve fiber performance and stability. For the setting process of high-performance fibers, the temperature of the heat setting box is as high as 400-500°C, and the temperature uniformity is required to be high, and the temperature control accuracy must be ±2°C. Conventional steam heating heat setting equipment has hig...
