Cooling water recycling system for dyeing vessel

Abstract

The invention belongs to the technical field of printing and dyeing equipment and particularly provides a cooling water recycling system for a dyeing vessel. The cooling water recycling system comprises the dyeing vessel. The dyeing vessel comprises a vessel body. The vessel body is internally provided with a plurality of hollow suspension bars and suspension bar connectors, wherein the number of the suspension bar connectors corresponds to the number of the suspension bars. The wall of each suspension bar is provided with a plurality of through holes. Inner cavities of all the suspension bars are connected with a water outlet pipe of a first water pump arranged outside the dyeing vessel though the suspension bar connectors and pipes communicated with the suspension bar connectors. A water inlet pipe of the first water pump is communicated with the interior of the vessel body. A cooling water outlet of the dyeing vessel is connected with a water inlet of a cooler through a pipe. A water outlet of the cooler is connected with a water storage tank. The water storage tank is communicated with an external water source through a pipe. According to the cooling water recycling system for the dyeing vessel, cooling water is cooled and recycled, consumed water in the dyeing vessel is supplemented through the external water source, the dyeing yield is increased, and the efficiency is improved. Water resources are saved, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing equipment, and in particular relates to a cooling water recycling system for dyeing vats. Background technique [0002] Tube dyeing is a common method of yarn dyeing, which is used to dye the yarn to be dyed into the desired color. The yarns to be dyed (including yarns made of various cotton yarns, linen yarns, chemical fibers, woolen yarns, real silk, etc., as well as yarns made of two or more blends of the above materials) must be dyed before being dyed. On the winding bobbins, several dyeing bobbins with yarns are strung together and fixed on the suspenders in the dyeing vat, and then dipped in the dyeing solution in the dyeing vat for dyeing. Silk dyeing is dyed by strand dyeing, and silk dyeing needs to be degummed, so that the amount of silk cannot be too much when twisted, and the silk must be loose to facilitate the penetration and circulation of the dye solution and make the ...

AI Technical Summary

Problems solved by technology

At present, no dye vats that can improve dyeing quality and efficiency have been seen, nor have they been found in materials and media reports

[0003] In addition, during the dyeing process, it is necessary to use cooling water to cool the dye vat; in conventional enterprises, the cooling water is directly discharged to the outside after use, which not only wastes water resources, but also easily causes environmental pollution
