Description
Technical field
The utility model relates to a kind of component for the supercritical carbon dioxide fluid dyeing machine, is specially the Double End construction machine sealing of supercritical carbon dioxide fluid dyeing machine.
Background technique
The working principle of supercritical carbon dioxide fluid dyeing is: more than liquid carbon dioxide is forced into critical pressure (7.38MPa) by high-pressure service pump by carbon dioxide, more than through heat exchanger, its temperature being heated to critical temperature (31.1 ℃) again, carbon dioxide now is supercritical state, supercritical carbon dioxide fluid enters in the dyestuff still that dyestuff is housed and fully contacts its dissolving with it, the dyestuff that then carries dissolving enters in the dyeing caldron that textile to be dyed is housed and realizes dyeing course, after dyeing finishes, supercritical carbon dioxide changes gaseous carbon dioxide into through the decompression temperature-fall period, through separating still, successfully separate, by cooling being recycled in carbon dioxide storage tank of condenser, participate in dyeing next time again, recycle.
With traditional water dyeing technique, compare, supercritical CO 2 dyeing technique has the following advantages: (1) not water, without contaminated wastewater deposits yields and discharge, textile enterprise needn't pay huge waste water treatment expense again, have the characteristics such as ecological, environmental protective and fabric variety wide adaptability, belong to the dyeing and finishing craft of environment protection type; (2) dyeing reduces pressure after finishing, and carbon dioxide gasifies rapidly, thereby does not need to dye post-drying, has both shortened technological process, has saved again the required energy of drying; (3) dyeing speed is fast, and level dyeing and through-dyeing can be good, and the reproducibility of dyeing is splendid; (4) carbon dioxide itself nontoxic, tasteless, do not fire, reusable; (5) dyestuff can reuse, and without adding the auxiliary agents such as any dispersing agent, levelling agent and buffer agent, has reduced cost of production during dyeing, has reduced pollution, has the plurality of advantages such as energy-saving and emission-reduction, is used at dyeing.
The double mechanical seal of existing supercritical carbon dioxide fluid dyeing machine produces magnitude of interference after by rubber corrugated pipe, installing and carrys out transmission, but the easy like this rotation that causes axle, and rubber corrugated pipe easily is torn, and causes seal failure, makes troubles to production.
Summary of the invention
The utility model is for the problems referred to above, the Double End construction machine sealing of supercritical carbon dioxide fluid dyeing machine is provided, its good seal performance, easy for installation, applied widely, long service life, stable work in work, be convenient to batch production, and cost is low, save manpower and time, had good economic value.
The technical solution of the utility model is: the Double End construction machine sealing of supercritical carbon dioxide fluid dyeing machine, comprise stainless steel stationary ring pad, the carbon graphite stationary ring, the carbon graphite rotating ring, the rotating ring fluororubber O-type ring, the stainless steel rotating seat, 65 manganese steel springs, stainless steel transmission drive sleeve, the teflon flange plate, the screw nail, it is characterized in that: described stainless steel drive sleeve both sides are provided with the stainless steel rotating seat, and stainless steel rotating seat inboard is provided with the carbon graphite rotating ring, carbon graphite rotating ring and stainless steel rotating seat directly are provided with the rotating ring fluororubber O-type ring, on the stainless steel rotating seat, be provided with 65 manganese steel springs, the carbon graphite rotating ring outside is symmetrically arranged with the carbon graphite stationary ring, carbon graphite stationary ring arranged outside has stainless steel stationary ring pad, on described carbon graphite stationary ring, be provided with the teflon flange plate, described carbon graphite rotating ring is connected with the stainless steel drive sleeve, in the stainless steel drive sleeve, be provided with the screw nail.
