Dyeing liquid circulating mechanism of cone yarn dyeing system

Abstract

The invention provides a dyeing liquid circulating mechanism of a cone yarn dyeing system. The mechanism includes a main pump, a cylinder body, a cylinder cover and a yarn frame; two cavities are formed in a yarn disc of the yarn frame, at least two yarn rods are arranged on the yarn disc, each cavity in the yarn disc is communicated with the corresponding yarn rod, a through hole is formed in each yarn rod, and two dye liquid access circulating ports are formed in the lower portions of the two cavities; a heat exchanger is arranged at the center of the yarn disc, and a dye liquid main pipe inlet of the heat exchanger is connected with an exchange outlet of the main pump; a first dye liquid outlet of the heat exchanger is communicated with the first dye liquid access circulating port, thesecond dye liquid access circulating port is communicated with an exchange inlet of the main pump through a first circulating reflux opening or a second dye liquid outlet of the heat exchanger is communicated with the second dye liquid access circulating port, and the first dye liquid access circulating port is communicated with the exchange inlet of the main pump through a second circulating reflux opening. The dye liquid circulating mechanism saves electric power, reduces the bath ratio and decreases the costs for treatment and dyeing. Treatment and dyeing in different directions are carriedout on cone yarn in two areas, and the treatment and dyeing efficiency are improved; color differences and dyelot chromatism are reduced, and a uniform dyeing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of package yarn dyeing, in particular to a dye liquor circulation mechanism of a package yarn dyeing system. Background technique [0002] Such as Picture 1-1 , as shown in 1-2, the water outlet of the main pump in the traditional bobbin dyeing machine is connected to the cavity provided in the yarn disc, and the cavity in the yarn disc is connected to the hollow yarn rod, and the dyeing liquid flows from the hollow yarn rod "from the inside to the outside "Dyeing, the dyeing solution after dyeing flows back to the water inlet of the main pump through the inlet and outlet of the cylinder, or the outlet of the main pump is connected to the inlet and outlet of the cylinder, and the dyeing solution flows to the hollow yarn rod "from outside to inside". The dyed liquor flows back to the water inlet of the main pump through the cavity in the yarn tray. [0003] The characteristic of the traditional package dyei...

AI Technical Summary

Problems solved by technology

Conclusion: The dye solution cannot be provided to two or three areas for dyeing at the same time, and only one-way "inside-to-out" dye solution flow can be done, without reverse "outside-to-inside" dye solution flow

[0005] Therefore, neither the existing bobbin dyeing machine nor the pulse dyeing machine can simultaneously dye the bobbins "from the inside to the outside" and "from the outside to the inside", resulting in a lower dyeing efficiency, a huge power consumption, and a high dyeing cost.
