Definitions

  • the invention relates to several methods and a device for cleaning a endless belt in a machine for manufacturing and / or finishing a paper, cardboard, tissue or other fibrous web with one Cleaning fluid that is applied to the tape and during and / or after the Cleaning together with loosened impurities at least essentially Scope is discharged again.
  • the cleaning fluid is applied to the tapes with high pressure sprayed and collected with the dissolved impurities.
  • the contaminated cleaning liquid then gets into the Waste water treatment of the company. This is relatively expensive.
  • the object of the invention is therefore the cost of cleaning and / or Reduce disposal of cleaning fluid.
  • the object was achieved in that at least part of the Contamination during the removal of the cleaning liquid from it is discharged separately and separately and / or the cleaning liquid with the Contamination is discharged into at least one collecting container.
  • the waste water from the machine is removed by the removal of impurities relieves and facilitates its preparation, which also affects the effort or affects the cost.
  • the collection of the resulting cleaning liquid also enables relief of the machine's waste water and the separate treatment of the Cleaning liquid of the collection container. Both have a positive impact on costs and may even allow the cleaning fluid to be reused or components thereof.
  • the collection container should preferably be the one that accumulates over several hours Can absorb cleaning liquid. Therefore, the capacity of the Collection container between 150 and 3600 l, preferably between 300 and 1500 l lie.
  • This size allows, especially with a movable design the collecting container is easy and easy to handle. So it is Operating personnel can fill a full collection container relatively easily replace empty, which of course can also be realized automatically.
  • the cleaning liquid can contain a reduced amount of the collecting container Contaminants are removed from the upper area of the collecting container.
  • the relatively lightly contaminated cleaning liquid that comes out of the collection container dissipated, can either be reused for cleaning or for Wastewater treatment of the machine.
  • the cleaning liquid should be in front of the Applied to the tape to be heated.
  • the energy required to heat the cleaning liquid can be used be significantly reduced when the thermal energy of the cleaning fluid during the discharge and / or in the collecting container for heating the for Cleaning the tape provided cleaning liquid is used.
  • the collection container should have a heat exchanger for heating the Have cleaning liquid.
  • An endlessly circulating, water-permeable belt 1 for example, As seen in Figure 1, a dryer of a dryer section of a paper machine sprayed with a cleaning liquid 6 for cleaning from a nozzle 2.
  • the dryer fabric guides the fibrous web 15 for drying around guide rollers 13 and heated drying cylinder 14 of the drying group.
  • the Cleaning device In order to be able to record the entire width of the strip 1, the Cleaning device have several nozzles 2 and / or transversely to the tape running direction be designed to be traversable.
  • the cleaning liquid 6 bouncing off the dryer fabric is used together with the dissolved contaminants from one connected to a vacuum source 12 Hood 3 suctioned off.
  • the discharged, dirty cleaning liquid 6 of several Cleaning devices enter a mobile system via a pipeline system 18 Collection container 9.
  • This collecting container 9 is located under the machine in the basement. The Movability of the collecting container 9 facilitates replacement by an empty one.
  • the nozzle 2 is located on the opposite side of the belt 1, a collecting device 4 for receiving the cleaning liquid 6 passing through the belt 1.
  • the nozzle 2 is here also from a hood 3 surround.
  • Both the hood 3 and the collecting device 4 are provided with a vacuum source 12 connected. This supports the recording and forwarding of the Cleaning liquid 6 to a separator 11.
  • the separator 11 directs the collected cleaning liquid 6 into a collecting container 9.
  • the collection container 9 has a capacity of 500 to 2000 l and can at least the amount usually obtained over a period of about 4 to 24 hours absorb on cleaning liquid 6.
  • the collecting container 9 is located on the drive side of the paper machine, so that the operation of the machine is not hindered.
  • the cleaning liquid 6 before the Nozzle 2 heated by a heater 5 heated by a heater 5.
  • the energy required for this can considerably through the use of the thermal energy in the collecting container 9 collected cleaning liquid 6 can be reduced.
  • the collected and still warm cleaning liquid 6 is in the heat exchanger 10 Thermal energy through the wall of the heat exchanger 10 to the for cleaning provided cleaning liquid 6, which leads to a preheating thereof.
  • the contaminants settle on the bottom from where they are together with part of the cleaning liquid 6 to a wastewater treatment 8 are performed.
  • This process of settling can still be done by adding binders are supported, which are dissolved in the cleaning liquid 6 Bind impurities.
  • the cleaning liquid 6 has in the upper region of the collecting container 9 a significantly lower proportion of impurities and can thus be used again Cleaning can be used.
  • this cleaning liquid 6 from the Collection container 9 is added to the fresh cleaning liquid 6 via a filter 7.
  • the collecting container 9 is mobile, i.e. With Wheels equipped so that a change of the collecting container 9 is possible without any problems is.
  • the cleaning liquid 6 passes through a filter 16 and is then over a High-pressure pump 17 led to a heat exchanger 10.
  • the heat exchanger 10 is in the collection container 9 and uses the thermal energy of the dirty Cleaning liquid 6 for heating the fresh cleaning liquid 6 out.
  • the cleaning liquid 6 heated in this way is then fed to the nozzles 2. Since the Heating of the cleaning liquid 6 takes place after the high-pressure pump 17, the pump and its seals are protected from thermal stress.
