Definitions

  • the invention initially relates to a method of the type explained in the preamble of claim 1. It relates in particular to the commercial laundry sector.
  • washing takes place in a substantially continuous pass through so-called countercurrent washing machines, to which the fresh water is fed at the machine end for washing the laundry.
  • the fresh water then flows from there with increasing contamination loading through the main washing and pre-washing zones.
  • the fresh water is heated in particular in the main washing zones by direct steam injection, for which the pressure of the saturated steam usually used in laundries is reduced from approx. 10-13 bar to approx Avoid entering the standing water baths.
  • the presence and work in the actual washing process with steam under pressure as a heating agent is an important prerequisite for the invention.
  • the rinsed laundry is usually dewatered by friction rollers, presses or centrifuges, the working speed of which is limited and which require additional energy to drive them.
  • the working speed of which is limited and which require additional energy to drive them.
  • the residual moisture rises abruptly when the cycle time falls below 2 minutes.
  • the energy used to drive such membrane presses is very high.
  • the investment costs for the provision of the drive current are correspondingly high.
  • the invention has for its object to develop the method of the type mentioned so that investment and energy expenditure for laundry drainage can be reduced.
  • the solution to the problem is laid down in the characterizing part of claim 1.
  • a part of the steam required in a known manner for heating the fresh water is thus previously used in the dewatering unit for pressing out the water from the laundry.
  • the steam is simply passed through the laundry itself, which, due to the natural pressure difference between the loading side of the laundry and the outflow side of the rinse water, requires no additional devices.
  • the one for draining due to its own pressure through the laundry Pressed-through steam ultimately condenses in a water reservoir downstream of the dewatering unit, through which all the fresh water required for washing flows and into which the rinsed water pressed out of the laundry is also introduced.
  • the wash water is heated to about 30-35 0 C.
  • the characterizing part of claim 2 essentially assumes that saturated steam with an initial steam pressure of approx. 10-13 bar is available in commercial laundries, which is used for heating heating registers in dryers or ironing surfaces in mangles and pressing devices.
  • the characterizing part of claim 3 takes into account that laundry is heavier or easier to drain depending on its nature. For dewatering cotton laundry e.g. an optimal steam pressure of 5 bar and for the dewatering of mixed fabrics of 2 bar. Mixed fabrics are easier to drain because of their polyester content.
  • the other features of the invention relate to the structural design of the drainage device.
  • the dewatering device essentially consists of a pressure vessel 1, the bottom 2 of which is provided with passage openings 3 forming a sieve.
  • the fresh water supply tank 4 which is under atmospheric pressure, into which water and steam passing through the through openings 3 are introduced and where this steam condenses at a temperature of approximately 15 ° C. due to the fresh water present.
  • the pressure vessel 1 can be closed with a removable pressure cap 5.
  • the pressure cap 5 provided on its side facing the pressure vessel 1 with a sieve-shaped wall 30 for steam passage contains a connection 6 for the introduction of the dewatering steam.
  • a plurality of pressure tappets 7 extend through the base 2 of the pressure vessel 1.
  • the pressure tappets 7 are driven from the bottom of the pressure vessel 1 in the direction of its fill opening 8.
  • the drive is carried out by pneumatic or hydraulic drive cylinders 9, which are arranged opposite one another on the outside of the pressure vessel 1 and act on a traverse 10 running below the pressure vessel parallel to the bottom thereof, to which the pressure rams 7 are rigidly attached with their lower ends.
  • saturated steam is available at a pressure of approx. 10-13 bar.
  • This steam is fed in the usual way - predominantly after reducing the pressure to about 3-5 bar - via lines 12, 13 for water heating of the washing machine and dishwasher 14.
  • the washing machine and dishwasher is supplied with fresh water from the fresh water supply tank 4 via the fresh water line 15.
  • the high-pressure saturated steam from the steam line 11 is fed through the steam dryer 16 to a pressure-reducing device designated overall by 17.
  • the steam is alternatively reduced to a pressure of approximately 2 bar via line line 18 or to a pressure of approximately 5 bar via line line 19 while simultaneously overheating.
  • the outlet of the pressure reducing device 17 is connected by a flexible hose 20 to the connection 6 of the pressure cap 5.
  • the high-pressure saturated steam is fed from line 11 via line line 18 or via line line 19 and through wall 30 of pressure cap 5 to the dewatering device.
  • the steam supply through the hose 20 is then released.
  • the steam flows through the laundry loaded with the rinse water, which covers the entire bottom 2 of the pressure vessel 1 in a uniform layer thickness.
  • the steam then passes through the passage opening 3 of the base 2 of the pressure vessel 1 and condenses within the fresh water supply tank 4, which is arranged below the pressure vessel 1.
  • the rinse water is essentially pressed out of the laundry and is also pressed into the fresh water supply tank 4, which is supplied with fresh water of about 15 ° C. inlet temperature through line 26.
  • the pressure cap 5 is raised again.
  • the pressure vessel 1 is around the axis 27 in its dashed tilt position pivots.
  • the drive cylinders 9 are actuated so that the pressure tappets 7 connected to them eject the laundry still adhering to the pressure vessel 1 from the filling opening 8 of the pressure vessel 1 onto the conveyor belt 28, on which the dewatered laundry in the direction of arrow 29 of the next processing station, for example a loosening device , is fed.
  • the steam still in the laundry is re-evaporated with the effect of further drying, so that with a residual moisture of approx. 35% an optimal deficiency or press moisture is achieved without further energy supply.
  • the pressure vessel has a diameter of 100 or 120 cm at a height of 60 cm, which corresponds to a capacity of 470 or 680 liters.
  • the total cycle time of the dewatering including the pure machine time takes approx. 90 seconds, the actual dewatering process i.e. the steam can act on the laundry for a maximum of 45 seconds.
  • the steam pressure can be adjusted between 1 and 6 bar depending on the desired residual moisture of the laundry.
  • the steam throughput during the actual dewatering process is 0.5 kg steam / kg laundry.
  • the initial temperature of the fresh water supplied through line 26 is approximately 15 ° C.
  • the inventive method heats up to about 30-35 ° C.
