Problems solved by technology

[0003] At present, the domestic dyeing and finishing equipment has the following problems: (1) The efficiency of dyeing and finishing equipment is low and the process time is long. The traditional overflow dyeing machine takes about 8-10 hours to dye a vat of cloth, and the dyeing cycle is long and time-consuming. Dyeing and finishing equipment made abroad takes 3 to 4 hours
(2) The pollution is large, and each cylinder dyeing requires a large amount of dye auxiliaries
(3) The water consumption is large. The water consumption per kilogram of fabric of the traditional overflow dyeing machine is large, which is about 47% more than that of the foreign-made dyeing and finishing equipment.
(4) Power consumption is large. The power consumption of traditional overflow dyeing machine per thousand kilograms of fabric is about 380 kilowatt-hours, which is about 47% more than that of foreign dyeing and finishing equipment.
[0006] The traditional dyeing water level can only reduce the high level of covering yarn by 20%-40%. The dyeing cycle is long and wastes water and electro-dyeing auxiliaries, causing environmental pollution.

Abstract

The invention discloses a high-temperature pulse flow yarn dyeing machine with an ultra low bath ratio and a control method thereof. The yarn dyeing machine comprises a dye vat, a creel, a heat exchange coiler, an adaptive water level monitoring device, a variable frequency motor, a three-level vane pump with an ultra low bath ratio and a dyeing computer. The method comprises the following steps: a time pulse generator in the dyeing computer gives out pulse flow data to a variable frequency motor controller to control the revolving rate of the variable frequency motor according to the set technological process; the variable frequency motor drives the three-level vane pump with an ultra low bath ratio to output dyeing flow in pulse flow type fluctuation; the output dyeing flow carries out adaptive adjustment according to an ideal reference model in the dyeing computer; the adaptive water level monitoring device gives out water-level reference identification information; and according to the information, a water level regulator and the variable frequency motor controller respectively regulate the water level and the variable frequency motor to reach the water level and the pulse flow required by the set technological process. The pulse flow dyeing technology in the invention conforms to the requirement of the minimum consumption of four factors, namely, water, energy, accessory ingredient and time for economical dyeing of ecological environment protection.

Description

technical field [0001] The invention relates to the field of yarn dyeing machine devices and process control, in particular to an ultra-low liquor ratio high temperature pulse flow yarn dyeing machine and a control method thereof. Background technique [0002] Package dyeing is the most widely used method in the yarn dyeing industry today. However, the bath of the conventional cheese dyeing machine is relatively large, and the dyeing cycle (especially the cotton yarn dyeing cycle) is long, and the time for heating, cooling, bleaching and washing accounts for more than half of the entire dyeing cycle, and consumes most of the dyeing cycle. water and electricity. In addition, the traditional method of unloading cheese from cheese dyeing machines is time-consuming and labor-intensive. Therefore, efforts should be made to develop short-process and environmentally friendly yarn dyeing technology. [0003] At present, the domestic dyeing and finishing equipment has the followin...
