Description
Technical field
This utility model belongs to fabric finishing technical field, is specifically related to a kind of horizontal anhydrous dyeing and finishing still.
Background technology
Dyeing and finishing is high pollution, highly water intensive industry, and water is most valuable resource.In whole dyeing and finishing production process, remove
Singe and outside mechanical finishing, all carry out in water, the wettest processing technique.According to measuring and calculating, the fabric of dyeing and printing process is useless with discharge
Water weight ratio is up to 1:150, and whole nation dyeing waste water discharge capacity estimates that the whole year is 1,000,000,000 tons, and cost for wastewater treatment is expensive, accounts for industry
The 35% of waste water total displacement, owing to its effluent adds multiple stain, auxiliary agent and precipitant, so being difficult to effective returning
Receiving, the cost that dyeing and finishing industry carries out environmental conservation is the highest.Along with the raising of national environmental standard with to workers ' health protection
Strengthening, environmental protection becomes one of problem in the urgent need to address in dyeing and finishing industry.
The appearance of supercritical carbon-dioxicle dyeing method achieves an important breakthrough of dyeing and finishing industry, supercritical titanium dioxide
Carbon dyeing kinetics is fast, is 5～10 times of traditional handicraft, and levelling and through-dyeing are good, and dyestuff and carbon dioxide can be reused, can
To exempt reduction cleaning and baking process, the carbon dioxide of use have do not fire, nontoxic, inexpensive, contamination-free in dyeing course
Discharge, is a kind of process for cleanly preparing without waste gas, waste water and waste sludge discharge.
Along with the research for supercritical carbon-dioxicle dyeing method is more and more deep, about supercritical CO 2 dyeing
The report of equipment and colouring method is the most of common occurrence, as number of patent application is: the Chinese patent of CN200610123053.8 is open
" dyeing caldron in a kind of supercritical CO 2 dyeing device ", integral dye still and dyeing caldron, in one, simplify conveying
Pipeline, reduces fluid flow resistance, and dyestuff dissolves and fabric absorption completes, for supercritical dioxy in a dyeing caldron simultaneously
Change carbon dyeing realizes continuous dyeing industrialization incessantly and has paved road.But this dyeing caldron can only realize dyestuff to be dissolved
With dyeing in one, it is impossible to realize the removing oil of fabric and follow-up rinsing process, the dyeing that some class are relatively low can only be produced
Fabric.And for example number of patent application is: the Chinese patent of CN200910231733.5 discloses " a kind of supercritical fluid dyeing machine ",
Including supercritical fluid dyeing still, fabric circulation loop and dyeing fluid circulating system, effectively realize the circulation of dyeing fluid, especially
Its fluid containing dissolving dye can be fully contacted with fabric and permeate in spray chamber system, is effectively improved the level dyeing of fabric
Property, also accelerate and contaminate in the absorption of dyestuff, be also equipped with separation and recovery and cleaning function simultaneously, fluids/gases, dyestuff can be realized
Separate and recover and recycle, from source, solving generation and the discharge of pollutant, there is significant ecological, environmental protective and cleaning
Productive prospecting.But this device structure is complicated, complex operation, it is impossible to complete removing oil in same dyeing caldron, dye and float simultaneously
The function such as wash.

With reference to shown in Fig. 1, described end cap 1 seals combination, described end cap 1 and kettle 3 junction by clip 18 and kettle 3
It is provided with the second double seal ring 19.Realize end cap 1 by clip 18 and kettle 3 combine, it is possible to achieve end cap 1 quickly open and
Close, convenient and swift.Arranging the second double seal ring 19 in end cap 1 and kettle 3 junction is to prevent end cap 1 and kettle 3 from tying
Gap occurs at conjunction, causes gas to leak.
With reference to shown in Fig. 1, described spool inner core 15 and end seal pipe 8 contact position are provided with the first double seal ring 10.By
Need regular to detach out, therefore, in order to prevent spool inner core 15 and end in end seal pipe 8 in spool inner core 15
Seal pipe 8 contact position and occur that gas leaks, the first double seal ring 10 is set at spool inner core 15 and end seal pipe 8 contact position,
The problem that can effectively solve gas leakage.
With reference to shown in Fig. 1, described end cap 1 is provided with safety filter tip 20.The purpose arranging safety filter tip 20 is to prevent still
Opened by mistake and caused security incident during the not up to normal pressure of the pressure in body 3.Due to after dyeing and finishing operation terminates, must emptying dyeing and finishing still
CO in body 32, when making pressure in kettle 3 reach normal pressure, pull-out spool inner core 15 of just can uncapping carries out discharging operations.If kettle 3
Interior pressure is not emitted into normal pressure, and due to the effect of pressure in still, safety filter tip 20 can compress self-locking device of uncapping, and prevents with pressure uncapping
The danger that brings of maloperation.
With reference to shown in Fig. 1, described bottom silently 7 is provided with support ring 11 with insulation urceolus 5 contact position.Setting of support ring 11
The suit of insulation urceolus 5 when meter is that dyeing and finishing still manufactures for convenience.
The above is preferred embodiment of the present utility model, but this utility model should not be limited to this embodiment and
Accompanying drawing disclosure of that, thus every without departing from the equivalence completed under spirit disclosed in the utility model or amendment, all fall
