Wastewater circulating dyeing system and method based on ultra-low bath ratio dyeing process

Abstract

The invention discloses a wastewater circulating dyeing system and method based on an ultra-low bath ratio dyeing process. The wastewater circulating dyeing system based on the ultra-low bath ratio dyeing process comprises a supporting plate, wherein the bottom of the supporting plate is fixedly connected with a supporting frame; the top of the supporting frame is fixedly provided with a circulating box and a dyeing tank; the circulating box and the dyeing tank are communicated through a feeding pipe; a material control mechanism is arranged in the feeding pipe; and a wastewater circulating mechanism is arranged in the circulating box. The wastewater circulating dyeing system and method based on the ultra-low bath ratio dyeing process provided by the invention relates to the technical field of dyeing processes. According to the wastewater circulating dyeing system and method based on the ultra-low bath ratio dyeing process, the wastewater circulating mechanism and a filtering unit are arranged, a first water pump and a second water pump are used for conveying water liquid, a filtering plate is used for filtering the water liquid, and the filtering plate is mounted by clamping a clamping rod and a mounting block, so that the recycling of waste liquid is realized, impurity particles can be prevented from falling into the next use, and the subsequent filtering efficiency is improved through disassembly and cleaning.

Description

technical field [0001] The invention relates to the technical field of dyeing technology, in particular to a wastewater circulation dyeing system and a method thereof based on an ultra-low liquor ratio dyeing technology. Background technique [0002] The dyeing process is the pre-dyeing treatment of the clothes. In order to make the clothes more evenly colored and increase the dyeing fastness, the stains on the clothes are cleaned before dyeing, and at the same time, the buttons and accessories on the clothes are removed to prevent damage during dyeing. When the fiber is immersed in the dye aqueous solution at a certain temperature, the dye will move from the water phase to the fiber. At this time, the amount of dye in the water will gradually decrease, and after a period of time, it will reach an equilibrium state; the dye that is reduced in the water is the dye that moves to the fiber; Take out the fiber at any time, even if it is twisted, the dye will still remain in the ...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides a waste water circulation dyeing system and method based on an ultra-low bath ratio dyeing process, which solves the problems of waste water directly discharged after use in the existing dyeing system, resulting in waste of materials and environmental pollution. In the recycling equipment, the next processing is often affected by the particulate impurities contained in it, and the repeated replacement of the filter screen will easily lead to the problem of low dyeing efficiency
