Definitions

  • the invention relates to a method for wet-treating objects preferably in a washing device as claimed in the preamble of claim 1 .
  • the invention relates to wet-treating, in particular washing, objects of all types, in particular the wet-treating of garments, the washing of containers, in particular the washing of containers for foodstuffs, the washing of bottles and washing systems for all kinds of vehicles and industrial devices, for example, conveyor belts.
  • Treatment liquid which has at least one treatment additive is used in the case of the wet-treatment of objects. From an environmental perspective, attempts are made to use the treatment liquid multiple times because even used treatment liquid still has unused treatment additives. A prerequisite for the re-use of used washing liquid, however, is that it still has sufficient treatment additives so that the objects to be treated next can be treated, in particular washed, to a sufficient extent.
  • the object underlying the invention is to create a method for wet-treating objects preferably in a washing device, by way of which method it is possible to measure the treatment liquid in a simpler manner.
  • This object is achieved by a method with the measures of claim 1 . Accordingly, it is provided preferably to branch off a small amount from the treatment liquid used and to be re-used as a sample and to measure only said sample. Thus it is no longer necessary to measure all the treatment liquid. As a result, it is possible to use a simple measuring technique which is set up for small sample amounts. After measuring, where applicable the small sample amount can be simply disposed of.
  • the method can be further developed such that the sample is filtered prior to the measuring, for example micro-filtration of the sample is preferably effected.
  • the filtration of the sample can also be effected in another manner and, where applicable, also in multiple steps.
  • the method can be simplified through the filtration of only small sample amounts. It is possible, in particular, to measure in a reliable and more accurate manner in this way. Because the sample only includes a small amount of treatment liquid, all the treatment liquid does not need to be filtered prior to the measuring.
  • the filtration of the sample containing only a small amount of liquid can be carried out rapidly and economically.
  • the sample can also be filtered using filtration methods which operate in a relatively slow but reliable manner.
  • the method provides for the sample being branched off from the used treatment liquid, preferably prior to the re-use of the same. This can be effected “in situ”. As the treatment liquid is separated from the objects to be treated prior to the re-use, the sample of the treatment liquid can be measured simply outside the washing device. As a result of the sample being branched off from the treatment liquid prior to the re-use, the measuring process supplies measurement results which convey the state of said treatment liquid in a timely manner prior to the re-use of said treatment liquid. As a result, the treatment liquid is able to be influenced, for example by the addition of at least one treatment additive before the treatment liquid once again serves for the wet-treating of objects.
  • An advantageous development of the method provides that the sample of treatment liquid to be re-used is taken after said treatment liquid has been returned again into the washing device and/or into a preparation tank for preparing the treatment liquid to be re-used for use in the washing device. Said method of operation ensures that the treatment liquid is measured in the state in which it is re-used, with regard to the desired properties.
  • the treatment liquid to be re-used is mixed from differently used treatment liquids or from both used and non-used treatment liquids, the mixture created thereby can be tested by means of the afore-described measuring process for its suitability directly prior to the treatment of objects to be washed.
  • the sample is branched off from the treatment liquid and/or measured during the operation of the washing device. In this way, it is possible to ascertain the state of the treatment liquid at a suitable point in time. For example, it can be determined in this way whether sufficient active washing substances are still present in the used treatment liquid.
  • a preferred development of the method provides for determining the remaining proportion of the at least one treatment additive in the used treatment liquid and for additionally metering the relevant treatment additive if a minimum proportion of the at least one treatment additive in the treatment liquid is undershot. In this way, it is ensured that even the re-used treatment liquid still has a sufficient proportion of the at least one treatment additive which is sufficient for washing the objects with the re-used treatment liquid.
  • a small sample hereof is preferably taken and measured once again. In this way it can be ascertained whether the additional metering was sufficient. Where applicable, through several targeted additional meterings it can be determined in a successive or iterative manner whether the additional metering is sufficient, and in this way the additional metering is performed in a targeted manner without resulting in excessive additional metering.
  • a preferred development of the device provides for determining the proportion of the active cleaning substances, disinfecting substances and/or active bleaching substances still present in the used treatment liquid during the current treatment operation.
  • these are the essential treatment additives which have to be present in the treatment liquid in a sufficient concentration so that the treatment liquid is able to be re-used.
  • the sample is drawn off, for example into a drain.
  • the method is suitable in the case of a washing device realized as a continuous-batch washing machine in order to re-use used treatment liquid from the continuous-batch washing machine for the pre-wash and/or the final wash.
  • used treatment liquid can be re-used in a particularly efficient manner.
  • treatment liquid from the pre-wash, the final wash and/or the rinse operation is re-used at least in a partial manner.
  • Treatment liquids from said treatment steps of the continuous-batch washing machine are particularly suitable for re-use because, as a rule, they contain a large proportion of unused active washing substances.

  • the draining device 11 can also be a draining press.
  • the draining device 11 serves for rinsing and draining the garments which are only washed in the continuous-batch washing machine 10 .
