Devices for treating fibrous materials with liquids are already known, in which the fibers are treated in a single treatment tank with several suitable liquids one after the other can be removed from the storage containers with the aid of compressed air or pressurized steam transferred into the treatment vessel and removed from the latter again. .

ίο The subject of the present invention forming device is now characterized in that the transferring the Liquids from the storage containers in the treatment tub and vice versa Air pressure in an air tank equipped with an air tap and water supply pipe Elevated tank is created in which the air is compressed by the inflow of water and transferred into the container receiving the various treatment liquids will so. that under the influence of the same

. the liquids can be introduced into the work vessels one after the other while ! the water after it does the work of air compression has performed, can even be used in the treatment tub and by emptying it for this purpose of the container mentioned to a new one by air flowing in its place Compression of the latter makes suitable or prepared.

In the accompanying drawing, the device is in

The fibrous materials to be treated, in particular strands of yarn, are arranged on a double frame A , which can be lowered into or lifted out of the treatment tubs C in a known manner by means of the press pot B actuated with compressed air. The storage containers D intended to hold the various liquids, the contents of which are to be transferred into the treatment tubs C , are arranged below these treatment tubs C or at some other suitable location. The following equipment is used to generate the compressed air required for this transfer:

On the one hand, an elevated tank M is connected to a pipe G , while on the other hand this pipe is connected to all of the storage tanks D by a corresponding number of pipes H (FIG. 3). Each of these pipes H is equipped with a three-way valve /, and through a suitable position of this, any storage container D can be connected either to the atmosphere or to the elevated container M or, in a known manner, finally to a storage container E provided for storing the compressed air which the air can optionally be introduced from the outside through a pipe F , are connected. If hot liquids are to be treated, the contents of the container D am

most expediently heated by means of steam, for the introduction of which the tube L is used. The container M is provided with a supply pipe N ¹ for water which is provided with a tap N and extends to close to the bottom of this vessel. If this tap is opened, then water enters the elevated tank M and compresses the air contained in the same, which in the sense of the arrows drawn ίο appropriate position of the three-way valve / get through the line H into one of the containers D and the liquid contained in this can press on the way through the line K into one of the treatment tubs or troughs C. If the tap -JV is closed and the water flow is turned off, the transfer of the liquid from the storage container D into the trough C will also cease. You can then, after the liquid in the trough C has come into effect, the same return in the manner mentioned in its storage tank D and the water contained in the elevated tank M z. B. use to wash the treated yarns. This is done by opening the air valve 0 of the elevated tank M and at the same time also the tap of the branch line arranged near the bottom of the elevated tank M, as illustrated in the drawing. As a result, the elevated tank M is made ready for the next air compression at the same time, in that it has been filled with air which can be compressed again after the tap of the branch line mentioned has been closed and the valve N has been opened. The pipes / tubes provided with valves serve to empty the treatment tubs, through which the liquid can always return to its own storage container by connecting a number of branch lines corresponding to the storage containers and opening into them. If the intention is to use the tanks E and M at the same time or alternately for this purpose, then the lines which connect the compressor E and the elevated tank M to the pipes H open into the common line G , which is also connected to the latter and equips the former with taps P and Q shortly before their confluence in the pipe G. The compressed air generated in the compressor E or in the container M can also be used to actuate the press pot B and thus to raise and lower the double frame A as required. Pat τ claim: Device for treating fibrous materials, in particular strands of yarn, in an open vat with liquids which are driven by air pressure from the storage containers into the treatment vat and vice versa, characterized in that the air pressure is provided in an air tap (O) and water supply pipe (N ¹ J) , designed as an air vessel (M) is generated, in which the air is compressed by the inflow of water and fed as compressed air into the reservoir (D) receiving the various treatment liquids to simultaneously convey the treatment liquids from these reservoirs (D) into the treatment tub (C) , while the water in the elevated tank (M), after it has done the work of air compression, can flow into the treatment tub (C) even for washing purposes through hydrostatic pressure and so the elevated tank (M) for a new compression of the one flowing in its place Makes air suitable. For this purpose 2 sheets of drawings.
