Dye vat water circulation system of improved structure

Abstract

The invention provides a water circulation system of a dye vat and belongs to the technical field of printing and dyeing equipment. The water circulation system can be used for solving the problem of serious water resource wastes during yarn dyeing in the printing and dyeing industry. The water circulation system of the dye vat comprises the dye vat, a cold water vat and a hot water vat, and is characterized in that the dye vat is connected with a water feeding mechanism capable of providing cold water to the dye vat; the hot water vat is connected with a water replenishing mechanism capable of replenishing hot water to the hot water vat; a connecting pipe III is communicated between the dye vat and the hot water vat; the hot water vat is communicated with a water inlet pipe of a water pump by virtue of a connecting pipe IV; a water outlet pipe of the water pump is communicated with the dye vat by virtue of a connecting pipe VIII; a connecting pipe VI is communicated between the connecting pipe IV and the connecting pipe VIII; the cold water vat is communicated with the water inlet pipe of the water pump by virtue of a connecting pipe V; a connecting pipe VII is communicated between the connecting pipe V and the connecting pipe VIII. The water circulation system can be used for recycling dirty water during yarn printing and dyeing, and saving water resources.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing equipment, and relates to a dye vat, in particular to a dye vat water circulation system with an improved structure. Background technique [0002] At present, the use of dye vats in the textile dyeing and finishing industry has been very common, and it is widely used in the dyeing of yarns. The yarn dyeing process is to place the yarn to be dyed into the dyeing vat, and then inject dye into the dyeing vat, and the dye is in contact with the yarn to achieve the purpose of dyeing the yarn. [0003] The yarn in the dyeing vat will leave a lot of foot water after dyeing, and some foot water contains a variety of harmful substances, and it needs to be purified before being discharged to the outside; for some foot water, it is Can be recycled and reused. In the prior art, after searching, for example, Chinese patent literature discloses a drainage control device for dyeing vats [patent num...

AI Technical Summary

Problems solved by technology

[0004] However, although the above-mentioned dye vat drainage control device can recycle the waste water in the dye vat, it cannot reuse the waste water, which seriously wastes water resources.
