Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] By analyzing the structure of the existing sizing machine oven, using CFD software to simulate the problem of poor fluid flow and uneven distribution of the internal temperature field during the operation of the oven, and on this basis, a new type of mechanism is proposed. This problem can be solved by improving the internal flow state and eliminating the unstable flow field structure. The overall flow chart is as figure 2 as shown,

[0031] One: Build a physical size model

[0032] Based on the traditional stenter heat setting machine, a 1:1 physical size model is established. Based on the 3D model of equal size, the simulation of the internal flow field and the verification after optimization are done.

[0033] Two: Carry out finite element-based fluid simulation

[0034] In order to carry out CFD simulation, the present invention carries out s...

Abstract

The invention discloses a baking oven structure of a tentering heat-setting machine. According to the invention, an eddy-break-up structure is arranged in the baking oven of the heat-setting machine,which solves the problems of hydrodynamic performance of the baking oven of the heat-setting machine during operation, improves an eddy structure which unreasonably exists in an original structure, optimizes a local flow field, obviously reduces eddy intensity, and solves the problems of excessive consumption of energy and hidden trouble of fire hazard due to unsmooth air discharge and easy accumulation of fiber dust at the eddy structure, and provides a base for energy saving and environmental protection, and safe production of the heat-setting machine.

Description

technical field [0001] The invention relates to the field of printing and dyeing heat setting machines, in particular to an oven structure for a tenter heat setting machine. Background technique [0002] The so-called heat setting is the process of placing the fabric in a high temperature environment (such as 180-200°C) under tension and maintaining a certain size or shape. After heat treatment for a period of time, it is then rapidly cooled. In this process, due to the good thermoplasticity of synthetic fibers, when placed in a high-temperature environment, the rearrangement of macromolecular segments causes great changes in the microstructure and morphology of the fibers, making the changed fiber microstructures Therefore, the main function of heat setting is to give the fabric a relatively stable size and shape. [0003] Since synthetic fibers and their blended fabrics have been subjected to dry and wet heat treatment for many times in the process of textile dyeing and f...
