Definitions
- the objects of this invention is the improvement of processes and apparatus for use in dyeing, bleaching, scouring and the like, so as to secure uniform treatment at low cost and in short time.
- these considerations are especially important in connection with the treating 'of textiles with peroxide bleach baths, I shall describe my invention in terms of its use with these solutions though not limiting its employment to bleaching liquors.
- Brieiiy my invention consists in forcing liquor in at a rate greater than that at which it flows downward through the material, or at a rate greater than that at which it is removed from the bottom of the kier.
- a further advantage of my invention is vsecured in greater certainty of even treatment due to the fact that the liquor needs pass through only half as much goods on its way back to the pump inlet for a given kier size as previously. If the bleaching action was very rapid my invention would result in cutting down the time of treatment; in some treatments, other than bleaching, the time is reduced. However, the bleaching action has a time factor, i. e. the bleach liquor must be in contact with the goods for a more or less definite period of time. My method now lallows this bleach liquor to be recycled through the kier a greater number of times than before in the same period; this increase in recycling increases the certainty of even treatment.
- Fig. I shows a kier having a single perforated liquor entrance.
- Fig. II shows a side-view and III an end view of a vat having several liquor entrances spaced from the kier wall.
- Fig. IV shows a kier provided with central and peripheral liquor inlets.
- Figs. V and VI show modifications of the liquor inlets.
- l is a kier or vat provided with a false bottom 2 beneath which-is the well 3.
- a cover 7 is provided for use, if desired, for
- the liquid feed pipe 9 is connected through valve 8 to the pipe line 6 at 25.
- the kier is further provided with an over-flow 14, which leads, by way of valve 15, and pipe 21, to the pump line 6 at' 26.
- a valve 24 is provided in the pump line between the junction points 25 and 26.
- the pump 22 is connected y way of pipe 17 to the inlet of the heater 16. This is provided with a heating means, such as a steam coil connected to 18 and 19.
- the pump inlet line 6 is connected through valve 27 to suitable mixing tanks or other source of treating liquor supply.
- the perforated pipe or distributor 13 may have any of several forms within the scope of this invention land I do not wish to be limited to a straight walled perforated pipe such as shown, nor do I wish to be limited to circular perforations.
- This distributor may A be ball shaped or have an rounded or irregular outline, suited or driving the streams of liquor in various diverging directions.
- the distributor 13 may' further be provided with perforations at the top of the pipe (Fig. V) which would increase the amount of liquor forced into the upper part of the kier load.
- the perforations in the distributor may be in the form of horizontal or vertical slits.'
- the perforations may further be made at an angle to the exterior of the distributor (Fig. VI) thus securing a flow which while in thel main would be toward the walls of the kier, nevertheless would be directed upward, e. g.v to secure an effect similar to that of a spherical distributor.
- the goods to be treated are packed in the kier so as to be as uniformly distributed as possible and the material put in to fill the kier at least to the top of the pipe 13, whatfever its length may be, cross chains or the -like may be fastened to the rings 20 to hold the goods. It is to be noted that a short pipe could be'provided in place of 13 as shown for treating small batches of goods in a large capacity kier. In that event it would be more economical to have a second overflow located below 14 in the same relation to the top of the distributor as that shown in re-l spect to 13 in the attached drawing.
- the material packed in the kier should preferably not extend above the overflow 14.
- The. start of the treating can be varied, but is preferably as follows:
- Valves 5, 10, 15 and 24 are closed; valve 8 is open.
- Valve 27 is now opened, allowing the treating liquors from the supply vessels to pass through pump 22 which is started so as to force the liquor upthrough the'heater and-'by way of pipe 9 and valve 8 through pipe 4 into the well of the kier at 3.
- This is the usual method of entering liquor into the Awell of a kier since it allows the air to escape from the kier while the liquor is entering. If the mixing tank is situated high enough, by opening valve 24 the liquor would, of course flow into the kier by gravity. lVhen sufficient liquor has been added to reach to or above 14, valve 27 is closed and my circulating system isstarted.
- Valves 10, 15 and 24 are now opened and valve 8 is closed thus allowing the liquor to be drawn through 14 and 4 to the pump 22 from which it is forced through pipe 17, heater 16, pipe 9, valves 10 to be discharged out of the perforated pipe or distributor 13.
- Some of the liquor in the goods will drain downward through the material to the woll 3, thence to the pump, thus securing in the lower section of the kier a combined horizontal and downward liow.
- the liquor inv excess of that flowing downward will flow, upward and leave the kier at 14.
- the amount of liquor taken from the well 3 can be regulated by opening or closing valve 24,
- the overflow can be regulated by opening or closing valve 15.
- opening or closing valve 15 since all of the liquor which is being discharged from pipe 13 is not allowed to escape through pipe 4 some of it will be forced to take an upward course and leave the kier through the overflow thus penetrating the goods in the upper section with a combinedhorizontal and upward flow.
- the invention then is seen to consist in distributing streams of liquor within the mass of goods under positive pump pressure and maintaining a. regulated dual outflow securing a simultaneous horizontal, upward and downward flow.
- the kier may be operated without utilizing the overflow 14 by closing valves 8 and 15. Since the liquor is discharged from 13 at a greater rate than it drains to the pump 22, and since some of the liquor will be displaced by gas remaining in the material it will collect on the top of the goods to some extent. It is of course realized that there is a definite amount of liquor in the kier, but there will be an increase in the height to which the liquor rises because of this contained gas.
- Another method of circulating the liquor which is advantageously used, is to draw the liquor through the overflow 14, valve 15 being open, down through pipe 21, valve 24 being closed, into pump 22, valve 27' being closed. thence through the heater 16, pipe 9, valve 10 being closed, down through valve 8, pipe 25 into the well of the kier through 4.
- the liquor would now pass upwards through the perforated bottom 2 and out at the overflow again at 14. If this circulation is used a readjustment of the goods placed in the kier is secured by pressure application in the direction opposite to the previous flow which thus assists in the even treatment of the material. This cycle further helps rid the kier of entrapped gases.
- the pump may be run so as to exert 'a definite suction on the streams coming from the kier thus tending to speed up the flow, i. e. by securing a forced drainage from the well 3.
- a steam injector means discharging directly into the pipe 13 or connected thereto from outside the kier could be used for circulating liquid in the kier in accordance with .my invention.
- Route 3 All of the liquor is drawn through 14and valve 15, to the pump 22 from which it passes through 17, 16 and 9 from which it is divided, part going through valve 10 to be discharged from 13 and the balance going through valve 8 to be discharged into the goods through the well of the kier.
- the kiers of my invention are therefore seen to have the widest'fleXibilit-y and adaptability to goods of various degrees of compactness and difficulty of treatment.
- Method of treating goods packedin a kier or the like which consists lin forcing multiple streams of treating liquor under positive pump pressure into the mass of goods at a rate greater than that at which liquor is removed from the bottom of the kier while simultaneously removing treating liquor from the top and bottom of the kier.
- Method of treating goods packed in a kier or the like which consists in forcing multiple streams of treating liquor under positive pump pressure into the mass of goods at a rate .such as to create a generally horizontal and upward as well as a generally horizontal and downward flow of liquor in the goods.
- Method of treating goods packed in a kier which consists in forcing multiple streams of treating liquor under positive pump'pressure into the center of the mass of goods while simultaneously removing treating liquor from the top and bottom of the kier.
- Method of treating goods packed in a kier which consists in forcing multiple streams of treating liquor from within the mass outward toward the Walls of the kier at a rate greater than that at which the treating liquor Hows downward through the mass while simultaneously removing treating liquor from the top and bottom of the kier.
- Method of treating goods packed in a kier which consists in forcing multiple streams of treating liquor from within the mass outward toward the walls of the kier at a rate greater than that at which the treating liquor is removed from the bottom of the kier while simultaneously removing treating liquor from the top and bottom of the kier.
