Arrangement structure of steam inlet pipe in steaming box

Abstract

The invention discloses a steam intake arrangement structure arranged in a steaming box and is used for leading fabrics to be equally steamed by hot steam on both breadth and length directions under any steam charging quantity. The structure comprises that: a plurality of steam intakes are arranged at the bottom of the box body, and a plurality of steam vents are cut on each steam intake. The structure is characterized in that the relation between arranging direction of the steam intakes and the arranging direction of a main cloth-guiding roller in the box body is 90 degree plus / minus 10 degree. The steam intake arrangement structure of the invention is mainly used for various steaming boxes.

Description

technical field [0001] The invention relates to a steam box in the field of printing and dyeing machinery, in particular to the arrangement structure of the steam inlet pipe in the steam box. Background technique [0002] In the printing and dyeing machinery industry, the steam box is a commonly used equipment, and saturated steam is usually used to steam and fix the color of the fabric in the steam box. Several steam inlet pipes are arranged at the bottom of the steam box, and many steam outlet holes are opened on the pipe wall of each steam inlet pipe. In order to ensure that the tank is filled with saturated steam, a water tank is generally arranged at the bottom of the tank, and the steam inlet pipe is arranged in the clear water in the tank. When working, steam is passed into the steam inlet pipe, and the steam emerges from the steam outlet hole on the steam inlet pipe to heat the clean water, so as to obtain reliable saturated steam. Such as figure 1 , as shown in F...

AI Technical Summary

Problems solved by technology

like figure 1 , as shown in Fig. 2 and Fig. 3, the arrangement structure of the traditional steam inlet pipe includes: some steam inlet pipes 2 arranged at the bottom of the steam box body 1, and several steam outlet pipes are provided on the pipe wall of each steam inlet pipe 2 Hole 21, the arrangement direction of the steam inlet pipe 2 is almost parallel to the arrangement direction of the main distribution roller 3 in the box, that is to say, the arrangement direction of the steam inlet pipe 2 is in line with the running direction of the fabric 5 in the box. Vertical; the shortcoming of this arrangement structure is: in the process of implementing the process, when the box is filled with saturated steam and reaches about 100 degrees Celsius, the actual steam consumed by the fabric 5 is very little during operation. In order to make rational use of steam, prevent If the steam is wasted, the operator will adjust the steam inlet valve, or use an automatic valve to control it, so as to reduce the amount of steam entering the steam box; After the reduction, on the steam inlet pipe 2, only steam emerges from the steam outlets 21 close to the steam inlet 22, and little or even no steam emerges from the steam outlets 21 far away from the steam inlet 22. , from the width direction of the fabric 5, the phenomenon that the amount of steam will gradually decrease, that is, as shown in Figure 2, the lower part of the box will be more steam than the The middle part and the upper part, which will cause color difference in the width direction for color fixing, and affect the quality of color fixing
