Package yarn liquid ammonia dyeing equipment

Abstract

The invention relates to a cheese liquid-ammonia dyeing device. The cheese liquid-ammonia dyeing device comprises a refrigerating unit, a dye preparing unit, a dyeing unit, a drying unit, a recycling unit, a ventilation unit and a conveying unit. The conveying unit is a connecting pipe and is connected with the refrigerating unit in a matched mode to complete conveying of liquid ammonia, dye and ammonia gas. A mechanical-arm dyed-piece placing unit and a control unit are adopted. The control unit is respectively connected with the refrigerating unit, the dye preparing unit, the dyeing unit, a mechanical-arm dyed-piece placing unit, the ventilation unit, the drying unit and the recycling unit in a matched mode. The mechanical-arm dyed-piece placing unit is matched with the refrigerating unit, the dyeing unit and the drying unit to achieve the aim that cheese is conveyed into the dyeing unit, conveyed into the drying unit and conveyed out of the drying unit. The refrigerating unit is composed of a refrigerating compressor and a freezing storeroom, the ventilation unit, the control unit and the freezing storeroom are installed together, the dye preparing unit, the dyeing unit and the recycling unit are arranged in the freezing storeroom, and the drying unit is arranged outside the freezing storeroom.

Description

technical field [0001] The invention relates to cheese dyeing equipment, in particular to liquid ammonia dyeing equipment for cheese, which uses liquid ammonia and dye mixed dyeing liquor to dye cheese. The invention is not only applicable to the dyeing process of the cheese in the liquid ammonia medium, but also applicable to the pre-finishing and post-finishing processes of the cheese in the liquid ammonia medium. Background technique [0002] With the increasing depletion of available water resources on the earth and the increasing environmental pollution, the traditional dyeing and finishing process using water as a medium has been severely challenged. According to relevant information, the situation of environmental pollution in China is very severe. As a big developing country, the task of energy conservation and emission reduction is becoming increasingly difficult. In order to reduce the pollution caused by the printing and dyeing industry, researchers have done a lo...

AI Technical Summary

Problems solved by technology

After research, the applicant found that when traditional cheese dyeing equipment is used for cheese dyeing, the winding of the yarn on the bobbin must be appropriate and good, not too tight or too loose, and the winding is too tight, and the dyeing solution is difficult to penetrate into the thick The yarn layer cannot form a virtuous circle, and the local color is lighter due to too little contact with the dye, resulting in color flowers or color circles, inner and outer layers and other dyeing defects

If the winding is too loose, the package yarn is easy to deform and fall off, resulting in messy yarn

Obviously, there are many deficiencies and problems in the traditional cheese dyeing equipment, which make it difficult to apply to the dyeing process of cheese in liquid ammonia medium

The applicant believes that there are many deficiencies and problems in the application of liquid ammonia dyeing technology in the traditional cheese dyeing equipment, which must be improved
