A yarn dyeing device

Abstract

The invention discloses a yarn dyeing device capable of maintaining temperature and concentration of dyeing liquid in multiple dyeing jars to be uniform. The yarn dyeing device comprises at least two dyeing jars, circulating pumps and angle control valves, each circulating pump and the corresponding angle control valve are matched with the corresponding dyeing jar, a spray pipe is arranged at the top in each dyeing jar, each circulating pump is communicated with the lower portion or the bottom of the corresponding dyeing jar through a liquid incoming pipe and communicated with a liquid inlet of the corresponding angle control valve through a liquid outgoing pipe, a spray liquid outlet of each angle control valve is communicated with the spray pipe disposed in the corresponding dyeing jar through a liquid outgoing pipe while a backflow liquid outlet of the same is communicated with a backflow port arranged on the other dyeing jar through a liquid outgoing pipe, and in this way, the dyeing liquid in all dyeing jars form big circulation, in other words, the dyeing liquid can flow in all dyeing jars. The yarn dyeing device can be widely applied to dyeing of various yarns.

Description

technical field [0001] The invention relates to a dyeing and finishing equipment in the textile industry, in particular to a yarn dyeing device. Background technique [0002] Currently, if figure 1 Shown, a kind of traditional yarn dyeing device, its structure comprises: the first dyeing vat 11 and the second dyeing vat 21, the first circulating pump 13 and the first angle control valve 15 for the first dyeing vat 11 supporting, and For the second circulating pump 23 and the second angle control valve 25 supporting the second dyeing vat 21, the top in the first dyeing vat 11 is provided with a first spray pipe 16, and the top in the second dyeing vat 21 is provided with a second Spray pipe 26, the first circulating pump 13 communicates with the bottom of the first dyeing vat 11 through the first liquid inlet pipe 12, and connects with the liquid inlet of the first angle control valve 15 through the first liquid outlet pipe 14 The second circulating pump 23 communicates wit...

AI Technical Summary

Problems solved by technology

Since the dyeing liquids in the above two dyeing vats are independent of each other, it is difficult to ensure that the temperature and concentration of the dyeing liquids in the two dyeing vats are consistent, which causes problems such as color difference in the yarns dyed by these two dyeing vats
