Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waterless dyeing, in particular to waterless dyeing mother liquor control equipment. Background Art
[0002] In the traditional dyeing process, we usually use water as the main medium. A large number of dyes, surfactants and other chemical substances will have an adverse impact on the sustainable development of the environment. In addition, the wastewater discharged from dyeing needs to be neutralized, settled and treated, which requires a lot of manpower and material resources. In order to solve the problem of wastewater discharge from dyeing from the source, in recent years, people have gradually shifted their attention to waterless dyeing methods. Common waterless dyeing methods include supercritical fluid dyeing, reverse micelle dyeing, vacuum sublimation dyeing, suspension system dyeing, organic solvent dyeing, etc. The common point of the above methods is to use other solvents or fluid systems to replace water, or to reduce the amount of water used in the dyeing process. After dyeing, water needs to be squeezed out through a roller, and the squeezed water is directly discharged, which causes waste; and the mother liquor is reduced after the cloth is dyed, and failure to replenish it in time will affect the dyeing process.
[0003] Therefore, in order to solve the deficiencies in the prior art, a simple-structured anhydrous dyeing mother liquor control device needs to be designed. Utility Model Content

[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] After the cloth is sent into the dyeing box for dyeing by the guide roller group, it is sent into the water squeezing box again. After some mother liquor is squeezed out by the internal water pressure roller group, it is sent out again. Because the mother liquor will become less after dyeing in the dyeing box, the mother liquor recovered in the water squeezing box is sent into the liquid storage tank above along the return pipe through the right water pump. At the same time, the left water pump sends new mother liquor into the dyeing box below through the liquid replenishment pipe.
