Device for the wet treatment of liquid-permeable goods

The invention relates to a device for wet treatment, preferably Washing or soaking of liquid-permeable goods that can be subjected to longitudinal tension such as cables, tapes, yarn, woven fabrics, knitted fabrics, Needle felt and tufted goods, fiber composites and the like in running web with a container which is at least partially filled with treatment liquid and in which screen drums flooded with treatment liquid are arranged, on which -the estate is run.

It is known to continuously wash such goods by means of sieve drum washing baths to treat. In the known devices, one or more screen drums under suction are in a treatment bath arranged one behind the other, which are either completely immersed in the liquid or only partially in the Immerse the liquid. With these devices, the liquor is sucked through the material by suction ner sieve drums and the goods are intensively wetted and cleaned during washing processes. . At high speeds it is advisable, in order to achieve a good effect, if the goods remain in the bath for a certain period of time. However, the known sieve drum washing baths have a relatively small immersion distance, i.e. the material is only used for a relatively short time Exposed to the effect of the liquor.

The invention has for its object to provide a device in which the advantages of the screen drum principle are maintained while the material a greater distance is passed through the treatment bath and thus a longer time is exposed to the fleet action without thereby significantly space requirements of such devices is increased.

Erfimhiii! ^r seeitiiül this object is easily .. 'else characterized irr - solves, since at least two sieve drums 3 over each other! i are inherited in the container. U.N; In order to achieve the greatest possible control of the screen drums, it is proposed that the screen drum be assigned a guide roller on both sides in the vicinity of the transfer area from one screen drum to the other.

Especially when this device is used to wash out the aids and unfixed dyes used in printing processes is, it is advantageous to assign at least one brush roller to at least one screen drum, the purely mechanically adhering Components solves.

It is possible to use the two screening drums as being under suction Train sieve drums. However, it is also possible to use the two Pressurize sieve drums so that the liquid is then out flows out of the sieve drums through the web-shaped material into the bath.

A particularly advantageous embodiment is obtained when one of the two screen drums is under suction and the other is under pressure stands. Here it is now possible to press the liquid sucked out of one sieve drum into the other sieve drum and so on to create a fluid cycle. For both sieve drums All that is required here is a pump facility. The 'on sow will' therefore correspondingly simple.

In an embodiment of this inventive concept, it is proposed that to put the lower sieve drum under suction and the upper one under pressure. It is then possible to lower the liquid level in the bath substantially, so that the upper drum screen at least partially, preferably largely outside the treatment bath, i.e. the treatment liquid, lies. With this device, you get by with a very small amount of liquor.

The diving distance of the property can be extended significantly by Arrangement of at least one further guide roller before and / or after the screen drums.
