Description

Technical Field

[0001] The invention relates to the technical field of textile dyeing equipment, and in particular to a cheese dyeing liquid circulation filtering device with a self-cleaning structure. Background Art

[0002] The wet dyeing of cheese yarn is achieved by immersing the substrate in the dyeing liquid and dyeing it through the reaction of the dyeing liquid under certain conditions. This means that after the cheese yarn is immersed in the dyeing liquid, due to the shedding of the cheese yarn's own material, solid impurities will be contained in the dyeing liquid. This means that after the dyeing liquid is recycled, the long-term accumulation of solid waste will cause a large amount of solid waste contained in the dyeing liquid to adhere to the raw materials and cause pollution to the finished product. The adhered solid waste is also not conducive to the coloring of the dyeing liquid. This means that when traditional dyeing equipment uses circulating dyeing liquid, it can only use a small number of cycles before replacing the new dyeing liquid. Adding solid waste separation equipment to the circulating equipment can effectively solve the problem that the above-mentioned dyeing liquid cannot be fully recycled. However, for the solid waste separation process, most of the existing equipment adopts static sedimentation or mesh filtration treatment methods. These treatment methods often have low treatment efficiency, and the solid impurities in the liquid circulation loop can easily clog the pipeline.
