Thepresent invention relates to machines for the wet treatment of textile materials or the like, and in particular to the washing, dyeing, bleaching, dressing thereof, or other similar operations.
In known machines of this type, the treatment bath is caused to circulate by means of a pump, propeller oi similar mechanism, either in a constant direction, or alternately in reverse directions, through a closed circuit including a treatment vat containing the material to be treated and an axial funnel passing through the center of the vat and communicating with the latter through the medium of two sets of perforated partitions which cause the bath to pass respectively from the vat into the funnel and from the funnel into the vat, one of said perforated partitions constituting the bottom of the vat. When the direction of circulation is modified, there is produced:
1. For one of the directions of circulation, a suction under the perforated bottom of the vat and a delivery into the axial funnel, the bath pouring from the upper part of the funnel on to the articles contained in the vat;
2. For the reverse direction of circulation, a suction through the top of the funnel and a delivery under the perforated bottom of the vat, which lifts the articles being treated and changes the location thereof.
When there are many not very permeable articles to be treated, the circulation is slackened' and the quantity of bath which pours out of the central funnel may be insufllcient for submerging the articles which are located near the outer wall of the vat. Moreover, in machines of small dimensions, the central funnel constitutes a hindrance for placing the articles to be treated in the machine and for removing them therefrom.
The present invention is intended to remove the above inconveniences and relates to a machine for the wet treatment of textile material or the like, in which the treatment bath is caused to circulate in a closed circuit through a vat containing said material and through another enclosure communicating with said vat by means of perforated partitions, said machine being characterised in particular by the fact that said chamber or enclosure is arranged entirely outside the vat containing the materials being treated. Said enclosure can completely surround the periphcry of the vat; it can also be constituted by one or more funnels or vessels arranged at one of the sides of the vat or distributed around the latter.
Claims. (Cl. 68--184) This arrangement leaving the vat entirely free allows of designing said vatin such a manner as to facilitate its operation or of improving its construction, as will be shown in greater detail hereinaften'and for instance of rendering easier the treatment of articles liable to become entangled, such as skeins, stockings, etc.
v A few embodiments of machines according to the invention are illustrated in the accompanying drawings, by way of example.
Fig. 1 is a vertical section of a first embodiment.
Figs. 2 and 3 are respectively a vertical section and a plan view of a second embodiment.
Fig. 4 is a vertical section of a third embodi ment.
According to the embodiment illustrated in Fig. 1, th machine comprises a hollow base or frame i supporting an outer vat 2 and, through the medium of radial arms 3, an inner vat 4 provided with a perforated false bottom 5. In a central opening 6 formed in the bottom 1 of the inner vat 4, can rotate a propeller 8 carried by a shaft 9 which passes through a stufling box In and on the lower end of which is rigidly secured a driving pulley ll actuated by the reversible electric motor l2. A draining nozzle l3 connected to the outer vat 2 may be opened or closed by a valve II.-
The inner vat is provided at its upper part with a perforated zone l5 which, in the example illustrated, is of truncated shape, but might be cylindrical,- and the entire surface of which has an area substantially equal to that of the surface of the perforated false bottom 5, so as to obtain similar conditions of operation for both directions of circulation of the treatment bath.
When the propeller 8 rotates in one of the directions of rotation, it sucks the treatment bath through the perforated bottom 5 and delivers it into the annular chamber [6 formed between the vats 2 and 4, from which the bath 'is again poured through the perforated zone l5 into the vat 4 which the bath must completely travel through in order'to again pass through the opening 6.
When the propeller 8 rotates in the reverse direction, it sucks the bath from the'chamber l6 formed between the vats 2 and l and delivers it through the perforated false bottom 5 into the vat l which the bath must completely traverse in order to return into the chamber it through the perforated zone l5.
It will benoted that,, whatever may be the direction of circulation, the vat 4 is traversed by be given a height appreciably less than that necessary for the central funnel of known machines having a central funnel. I
A cover I2 can be placed on the upper opening of the vat of the machine; a packing I3 clamped by screws 14 allows of ensuring fluid-tightness and of either exerting a certain amount of pressure. on the surface of the bath, or of working under a certain degree of vacuum. The existence of pressure on the surface of the bath allows the propeller to work efficiently and to sustain an active circulation even when the temperature approaches, reaches or even exceeds 100 centigrade. In fact, the existence of said pressure avoids the product of steam on the side of the orifice through which the propeller sucks the bath; the output of said propeller thus remains constant at all temperatures. This arrangement offers particular advantages for centain operations which must be eflected at a temperature higher than 100 centigrade, such as the bleaching of cotton for instance. The working under vacuum on the contrary, is useful in some treatments, for instance for avoiding oxidation.
The form of construction illustrated in Figs. 2 and 3 comprises three vertically superposed sections. The central section is composed of two cylinders I1 and I8, the cylinder I! which forms the treatment vat being provided with a perforated bottom I9 and the cylinder l8 being internally lined with a heating packet 28 and being traversed by a shaft 2| which carries the propeller 22 and the upper extension of which is supported by bearings 23 and carries the driving pulley 24 actuated by the reversible electric motor 25.
The upper and lower sections form two collectors 26 and 21 connecting the cylinders I1 and I8 and are laterally limited, in the example illustrated, by two planes tangent to the upper and lower extensions of the cylinders I1 and I8 and by the parts of said extensions located outside the tangential planes between said extensions, as shown in the plan view of Fig. 3. The lower section 21 is closed by a solid bottom 28 on which bear the struts 29 supporting the perforated bottom I3. The cylinder II extends into the upper section 26 as a tubular member which may have the shape of a perforated cylinder of the same diameter as cylinder I1, or the shape, illustrated in the drawing, of a double frustum, one inverted constituted by a solid wall 36 and the second 3i being perforated and fitting through its large base over the upper part of cylinder II, the surface of the perforated frustum 3| being approximately equal to that of the perforated bottom I9.
The bearings 23 and the motor 25 are carried by an upright 32 secured on a shoe member 33 on which the machine rests, the bottom 28 being secured to the shoe 33 by bolts 34 which prevent it from distorting under the suction action of the propeller.
The heating of the bath can be ensured in the known manner by-a direct admission of steam into the bath. Said heating may also be indirect and ensured by the Jacket 26 constituted by two cylinders concentric with the propeller and joined drained through the nozzle 36.
being admitted through condensed water being The draining nozzle 3'! allows of evacuatingthe bath from the machine.- 1 I The operation of the machine is obviously similar to that of the machine illustrated in Fig. 1. v This second embodiment allows of doing away with the ,stufling-box of the example of Fig. 1,
at their bases, the steam the inlet pipe 36 and the and of constructing a machine of lesser height, in which all the mechanical part is very accessible and does not risk being deteriorated by leakages of the bath.
As regards the reheating jacket 26, in addition .to the known advantages of indirect heating (con- -stant volume of the bath, etc.) it offers the further advantage of being easy to construct and of necessitating only a small exchange surface, owing to the speed of thebath, to its turbulence in the cylinder I8 and to the rapidity of the heat exchanges resulting'therefrom.
Instead of a single cylinder I8, two or more cylinders similar to cylinder I8 might be distributed around the vat II.
Finally, the embodiment of Fig. 4, more particularly intended for machines of large capacity, combines the known circulation through a funnel at the centre of the treatment vat with the circulation, according to the principle common to the examples described above, through a space on the outside of said vat. A frame II ll constituting the frame of the machine carries, on a central member III and on brackets II2, a vat II3 comprising at its lower part a draining valve H4. The central member III the medium of radial arms II5, the treatment vat II6 the solid bottom II! of which is of frustum shape and which is moreover provided with a perforated false bottom H8. The lateral walls of the vat II6 have, near the upper part thereof, a perforated zone having for instance the shape of a frustum 9. A shaft I20 carried in bearings housed in the frame I I6 and driven by the reversible electric motor I23 is arranged along the common axis of the vats I I3 and' I I6 and carries, near the lower end thereof, two propellers I24 and I25 respectively housed in a central opening of the bottom II I and in a central opening of the false bottom II6, the blades of these two propellers being inclined in reverse directions.
Above the perforated false bottom I I8 is mounted in the known manner a solid central funnel I26 surmounted-by a perforated cone I21. The total area of the perforated surface of said central cone I 21 and of the surface of the perrated zone H9 is substantially equal to the "surface of the perforated false bottom II8.
Two concentric heating bodies I28 and I 29 are each constituted by two cylinders connected at their lower ends, as in the example of Figs. 2 and 3, the steam being admitted through the inlet pipe I36 and the condensed water being removed through the pipe I3I.
For one of the directions of rotation of the motor I 23 and consequently of shaft I20, thebath will be sucked from the space comprised between the bottom II! and the false bottom I I8 and delivered by the propeller I25 through. the central funnel I26 and the perforated cone I21 and by the propeller I 24 through the space comprised between the vats II3 and H6 and through the perforated zone II8 so as to fall on to the articles contained in the vat II6. For the reverse direction of rotation, the bath will be sucked from the vat II6 through the perforated zones II and I21 thus supports, through and will be delivered in the space comprised between the bottoms ll'l and H8 and through the perforated false bottom H8, lifting thereby the articles located on said perforated false bottom.
The invention is obviously not limited to'the embodiments described above and which have been given only by way of example, and modifications may be made thereto without departing from the scope of the invention. Thus, in the various embodiments, a cover can be applied on the machine in a manner similar to that illustrated in Fig. 1, for allowing the treatment to be effected under pressure.
