Ultra-low bath ratio yarn dyeing machine water-squeezing device and squeezing method thereof

Abstract

The invention discloses an ultra-low bath ratio yarn dyeing machine water-squeezing device and a squeezing method thereof. The water-squeezing device comprises a pneumatic rotating cylinder, a driving shaft, a swinging arm, a connecting rod, a semilunar valve plate, a sleeve valve ring, a compressed air water-squeezing valve and an accumulated water discharging valve. During water squeezing, the sleeve valve ring rotates to use the semilunar valve plate to block the sucking water inlet of a three-stage impeller pump and block the communication between the sucking water inlet and a main cylinder, dyeing liquid in the main cylinder and air cannot enter the three-stage impeller pump through the sucking water inlet to form a breaking state, a computer controls to add compressed air to the main cylinder, the accumulated water discharging valve is opened, a compressed air passage can only communicate with the main cylinder of a dyeing machine through a yarn disc dyeing liquid reflow inlet, and when the water inlet of the three-stage impeller pump blocks the sleeve valve ring, the dyeing liquid reflow inlet and the main cylinder are separated by a spindle, the compressed air can only be exhausted by the accumulated water discharging valve from the yarn disc dyeing liquid reflow inlet after passing through the spindle, and water is removed. The ultra-low bath ratio yarn dyeing machine water-squeezing device is simple in structure, the water using amount of the dyeing machine is not increased, the dyeing time can be shortened, and the dyeing efficiency is improved.

Description

technical field [0001] The invention relates to a water squeezing device for an ultra-low liquor ratio yarn dyeing machine, in particular to a water squeezing device and a water squeezing method for an ultra-low liquor ratio yarn dyeing machine. Background technique [0002] The water squeezing device used in the traditional cheese dyeing machine needs to increase the bath ratio of dyeing, and the cleaning water saved by the traditional water squeezing device is offset by the increased water of the traditional water squeezing device, so it cannot be popularized and used. Ordinary dyeing cannot meet higher-grade dyeing requirements due to the limitation of technological process and equipment conditions. First of all, the traditional dyeing process is long (cone yarn→water intake→add dyestuff→add sodium carbonate→add soda ash→circulate for 30min→pulse washing water→water level drainage→water intake→soaping→water level drainage→dehydration→drying→ Winding→Completion), every li...

Ordinary dyeing cannot meet higher-grade dyeing requirements due to the limitation of technological process and equipment conditions

First of all, the traditional dyeing process is long (cone yarn→water intake→add dyestuff→add sodium carbonate→add soda ash→circulate for 30min→pulse washing water→water level drainage→water intake→soaping→water level drainage→dehydration→drying→ Winding→Completion), every link will easily cause the dyed yarn to increase the drainage time, cause the residual water of the spindle to be left for the next process to clean, etc., resulting in unnecessary loss and waste, and bring winder to the subsequent process. Difficulties in rewinding and drying
