Device for washing out lye from web material, in particular for stabilizing mercerized, textile goods "

description

The invention relates to a device for washing out of lye from sheet material with a washing tank, In which In the guiding direction of the web material one behind the other Immerse several guide rollers, one for each Support roller for the web material is assigned, the washing liquor being pumped out via a pump and via a Liquor distributor pipe is fed back to the washing tank from above the rollers in a circuit, in particular for stabilizing mereroerized, textile goods.

Such a known device, that of a mercerizing machine is connected downstream consists of one or more such washing containers located one behind the other. The A common feature of the washing containers is that several guide rollers are immersed one behind the other in the washing container. In One and the same liquor is circulated in the same concentration in each washing tank. Associated with each washing container is a collecting container with a circulation pump and liquor distributor pipe.

However, this is particularly disadvantageous in that it is satisfactory Washing out of the web material requires a great deal of fresh water, or a correspondingly enlarged washing container or several such washing containers connected in series. You save on washing water or on equipment Effort, the lye is often not washed out satisfactorily.

The invention avoids these disadvantages. It is based on the task of a device for washing out To propose lye made from web material that manages with little washing water or little expenditure on equipment.

Based on a device of the type mentioned at the beginning this is achieved according to the invention in that the washing container is divided into sections by an overflow plate, for each guide roller with an associated overlay roller in one section each, and that each section has one ® £ g @ n © is assigned to a circulation pump with a liquor inlet pipe.

By means of these structurally simple measures, the washing container (Stabilization compartment) divided into sections and there is a precise countercurrent of the wash liquor · from Achieved section to section. The concentration of the liquor is therefore greatest at the entrance of the WasohbehSlters, which is where the pollution is of the web material is largest. That is, it is with an approximately constant gradient · between Soiling and liquor worked, which results in an excellent degree of efficiency. This is an essential Saving of washing water goes hand in hand, so that when washing out the Was® a much better result is achieved.

The subdivision of the washing container into the sections is further improved if each section has an iauchbleeh is shielded from the section in front of it. That Dew shield largely prevents the wash liquor from crossing over from the relevant section to the one in front of it Section directly from the guide roller, that is, without this liquor being with the liquor in the relevant section has mixed beforehand.

Jg-

It also contributes significantly to water savings, if a basic amount of fresh water is supplied to the washing container at the outlet and separated from it a control quantity of the fresh water, with the weak liquor at the inlet being used in a control circuit the regular quantity controls. This ensures that the basic amount of fresh water is always at the outlet of the Vaschbehälters is supplied, whereby the desired concentration ionsgtfalle is achieved. Only a rule set ent " Depending on the amount of weak liquor withdrawn in each case, the washing container is placed in the middle or front area fed, that is, in an area where the liquor is already noticeably soiled.

The invention is illustrated below with the aid of an exemplary embodiment explained in more detail, from which further important features result. It showed

Fig. 1 - a scheme to explain the essentials

Features of the novel device, namely a washing container with the essential associated Components in a schematic side view;

Fig. 2 - a section of the washing container as a detail naoh Fig. 1 to illustrate the structural details of this section;

Fig. 3 - a detail similar to Fig. 2 for explanation the circulation device for the liquor;

Fig. 4 - a scheme to illustrate the control for the fresh water.

In FIG. 1, a wax container 1 which is open at the top is schematically shown shown by the textile webs to be stabilized from an entrance 2 in the direction of the arrow 3 to a Output 4 can be performed. The washing container is through overflow plates 5 - see also FIG. 2 - divided into sections 6 in the transverse direction. One appears in each section Guide roller 7 into the liquor, in front of and behind each of which a lay-on roller 8 is located. Besides, in front of everyone Guide roller and a dip plate in front of each overflow bleoh

6 provided, which is immersed in the fleet and to a feeling * Survivable portion from the fleet to the top. The dive Sheet metal is to a small extent attached to its guide roller 7 * tends.

FIG. 3 also shows that each section is assigned to a circuit for the liquor, consisting of a suction pipe 10 connected to the section with a pump 11 and liquor inlet pipe 12, which is above the relevant guide roller

7 opens.

The control scheme according to Fig. 4 shows that a · basic amount of fresh water via a manual setting 13 in the direction of the Arrow 14 is fed to the outlet 4 of the washing container 1. A regular amount of fresh water is in the direction of the arrow 15 is fed to the washing container via a control valve 16 and a feed pipe 17. This inlet pipe is about the front third of the washing container 1.

The control valve 16 is in a control circuit 1Θ of a Sensor 19 is applied, which is the amount of weak liquor which occurs in the direction of the arrow and is withdrawn from the washing container 1 measures.
