Embodiment 1

[0024] like figure 1 and figure 2 As shown, the present embodiment includes a tank body 1 and a cover body 11 hingedly fitted therewith, and also includes a partition 4, which is fixed on the inner wall of the tank body 1 and separates the inner peripheral wall of the tank body 1 into inferior parts located in the upper section. The arc wall and the superior arc wall located in the lower section, an interlayer is arranged on the inner wall of the tank body 1, a plurality of steam injection nozzles 2 are fixed on the inferior arc wall, and the partition plate 4 and the interlayer form a steam flow channel 3, A support plate 6 is installed on the superior arc wall, and a plurality of steam spray holes 7 are opened on the support plate 6 , and exit holes 8 corresponding to the steam spray holes 7 are opened on the steam channel 3 .

[0025] In the prior art, when the gray cloth is fixed, the steam is directly introduced from the side of the tank body 1, and the steam at the ste...

Embodiment 2

[0027] like figure 2 As shown, in this embodiment, the upper surface of the support plate 6 is covered with an insulating cloth 5, and a drainage channel 10 is opened at the lowest point of the arc wall. During the color fixing process, a large amount of steam directly interacts with the gray cloth through the steam injection holes 7 to ensure sufficient diffusion and penetration of the dye, so that the dye is fully combined with the fiber, but because the steam realizes point-to-point contact with the gray cloth through multiple steam injection holes 7 , the temperature at the contact point of the two is the highest, and it is easy to cause local overheating. In this embodiment, a layer of isolation cloth 5 is covered on the upper surface of the support plate 6, and the conductivity of the steam on the isolation cloth 5 is used to allow the steam to pass through. The insulating cloth 5 and the bottom of the gray cloth are fully and fully contacted, so as to prevent the gray ...

Embodiment 3

[0031] like figure 2 As shown, in this embodiment, the baffle 4 is arranged in a circular arc shape. Compared with the flat baffle 4, the smooth surface of the baffle 4 can be used to guide the steam ejected from the steam nozzle 2, avoiding The steam bounces and hits on the separator 4 to ensure the flow rate of the steam so as to improve the color fixing efficiency of the gray cloth.

Abstract

The invention discloses a printing steaming tank. The printing steaming tank comprises a tank body, a cover body and a separating plate, wherein the separating plate is fixed to the inner wall of the tank body and divides the inner circumferential wall of the tank body into a minor arc wall located on the upper section and a major arc wall located on the lower section; an interlayer is arranged on the inner wall of the tank body; a plurality of steam spraying nozzles are fixed to the minor arc wall; a steam runner is formed by the separating plate and the interlayer; a supporting plate is installed on the major arc wall and provided with a plurality of steam spraying holes; and the steam runner is provided with jetting holes corresponding to the steam spraying holes. Before interacting with gray fabric, steam moves by a certain distance in the steam runner until moving into a steam collecting cavity, and the temperature of the steam is gradually decreased in the moving process of the steam, so that the steam concentrated in the steam collecting cavity does not become overheated steam. Thorough diffusion and permeation of dye are guaranteed, the dye is thoroughly combined with fibers, coloring of active and acid dye is facilitated, and color differences between lab samples and bulk samples and large shade differences of the gray fabric are avoided.

Description

technical field [0001] The invention relates to a steaming tank, in particular to a printing steaming tank. Background technique [0002] The process of reactive dye printing includes white cloth printing—drying—steaming (102~104°C, 5~7min) or baking—cold running water rinsing—hot water washing—soaping—hot water washing—cold water washing—drying. Among them, the steaming process, that is, the color fixing process, the reaction speed of reactive dyes and fibers increases with the increase of temperature. High temperature treatment at a certain humidity is conducive to the full diffusion and penetration of dyes, so that dyes and fibers can be fully combined. Depending on the reactivity of the dye, the steaming time can be extended to 8-10 minutes for dyes with a slow reaction rate. [0003] In the prior art, a steaming tank is usually used for color fixation, but the steaming tank is designed to directly enter the steam from the side and bottom, and does not have any cooling ...
