Title:
MULTI-PIPE QUANTITATIVE MEDIUM REFILL SYSTEM OF SUPERCRITICAL FLUID ANHYDROUS DYEING MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/206195
Kind Code:
A1
Abstract:
The present invention relates to a multi-pipe quantitative medium refill system of a supercritical fluid anhydrous dyeing machine, comprising a supercritical fluid medium reservoir, a cutoff valve, and a medium filter connected in series via a high-pressure main pipe, and at least two or more refill branches mutually independent and at the same time connected to the medium filter, each refill branch correspondingly comprises a booster pump, a supercritical fluid high-pressure mass flowmeter, a high-pressure ball valve, and dyeing units connected via a high-pressure branch pipe in the direction in which a medium progresses. The present invention, by means of the refill system employing the mutually independent multiple branches of a mass metering mode, effectively implements simultaneous and accurate quantitative medium refill with respect to the multiple independent dyeing units, and differentiated refill for different medium masses for the different dyeing units, thus overcoming the shortcomings of unreliability, inaccuracy, and low use efficiency of a conventional method and, at the same time, making a dyeing operation simple and scientifically feasible.
