Definitions

  • the invention relates to a washing device according to the preamble of the main claim.
  • a device of this kind is in German patent application P 196 14 395.0-27 the applicant of April 12, 1996.
  • the device serves under another of cleaning a cylinder in a printing press, the device with a circuit for the supply and discharge of cleaning fluid (Detergent / solvent and / or water) with the interposition of a treatment plant is coupled.
  • the cleaning device are used as a treatment plant at least two for the used (contaminated) cleaning fluid Sedimentation devices arranged in series. These separate using gravity suspended the cleaning fluid into the three components Solids, detergents / solvents and water.
  • EP 0 531 773 B1 is a device for washing a printing press cylinder known as a treatment plant a distillation unit and a downstream gravity separator, which the distillate in water and separates solvent. After separation, water and solvent individually and successively fed back to the washing device.
  • DE 31 20 983 A1 describes a device for washing the blanket cylinder an offset printing machine known.
  • the device has one Washing roller, here referred to as a brush roller, cleaning a blanket cylinder serves in an offset printing machine.
  • the cleaning device has, among other things, a special design of the housing. This is said to be an undesirable Spraying washing liquid on other parts of the printing machine be prevented. Furthermore, the bottom of the housing is used as a tub Collect used washing liquid and trained from contamination. The washing liquid is not prepared.
  • a spray nozzle which has a cleaning liquid jet, intermittent, among other things, along the bottom of the case Pan causes soiling as well as the washing liquid in the direction flushed to a drain and thus the accumulation of contaminants, which can prevent it from settling out as mud and liquid.
  • the washing liquid is also the use of water for the cleaning fluid jet possible.
  • the object of the invention is to develop a solution by which the accumulation of contaminated cleaning fluid at the bottom of the housing Washing device is avoidable.
  • the advantage of this design is that flushing with pre-cleaned cleaning fluid prevents the accumulation and possibly the accumulation of contaminated cleaning fluid in the housing. Clogging of the drain opening is also prevented. Is preferred during the operating position Washing "the housing base of the washing device is continuously flushed out by the pre-cleaned detergent. Alternatively, the flushing can also be operated intermittently. It is also advantageous if the flushing of the cylinder jacket surface is maintained for a short time afterwards. This ensures that contaminated cleaning fluid flows away better through the use of used, but pre-cleaned cleaning fluid, additional consumption of cleaning fluid is not required in terms of quantity, since detergent already in circulation can be used for the flushing.
  • a washing device 1 is assigned in a printing unit of an offset printing press to a cylinder 21, here the blanket cylinder, adjacent.
  • the washing device 1 has a housing 2 which has an approximately rectangular cross section and extends beyond the full width of the cylinder 21.
  • the housing 2 accommodates a rotatable, separately drivable washing roller 11, for example a washing brush equipped with brushes.
  • Spray nozzles 18 arranged in a row on the housing 2 are directed onto the washing roller 11 and are coupled to a water supply.
  • a doctor blade 19 which interacts with the washing roller 11, and also a cleaning fluid supply which is likewise directed onto the washing roller 11 and which, by means of a row of spray nozzles 20, wet the washing roller 11 with a vegetable detergent.
  • a nozzle 4 is arranged on an end face 3 of the housing 2 and is coupled to a feed line 9 for the pre-cleaned cleaning fluid (detergent).
  • the sedimentation device 7 represents a receptacle for the contaminated cleaning fluid, which, in addition to the cleaning fluid (detergent) and water used, is also contaminated with contaminants such as color residues, paper dust, powder, sludge, and possibly paint residues.
  • the return line 6 coming from the washing device 1 opens in the vicinity of the bottom of the sedimentation device 7.
  • the feed line 9, which is coupled to the washing device 1, begins in the central region of the sedimentation device 7.
  • An overflow line 14 is arranged in the upper area of the sedimentation device 7 and is coupled to a receiving container 15 for cleaned detergent.
  • a supply line (not shown) leads from the receptacle 15, possibly with the interposition of a filter or other treatment system (further sedimentation device), to the spray nozzles 20 of the washing device 1.
  • the feed line 9 leads pre-cleaned cleaning fluid 12 with the interposition of a filter device 8 and pump to a nozzle 4 which is arranged in the region of the end faces 3 of the washing device 1.
  • the bypass line 10 is used to set the pressure for flushing in the feed line 9 and the filter 8 is operated as a crossflow filter (self-cleaning).
  • the pre-cleaned cleaning fluid 12 can be acted upon by the nozzle 4 and generates a flow 17 in the direction of the outlet opening 5 at the bottom of the housing 2 of the washing device 1.
  • a plurality of nozzles 4 coupled to the feed line 9 can be arranged across the width of the housing 2 to generate a common flow 17 in the direction of the discharge opening 5.
  • the drain opening 5 in connection with the return line 6 is preferably connected to an intermediate suction device.
  • a nozzle 4 is arranged in the region of each end face 3, the drain opening 5 is arranged centrally in the housing base. Every nozzle 4 has a separate feed line 9, which is coupled to the sedimentation system 7 is.
  • the housing 2 of the washing device 1 has an advantageous design a slope leading to the next drain opening 5.
  • the spray nozzles 18, 20 wet the washing roller 11 with water and / or cleaning fluid (detergent).
  • the washing roller 11 is placed against the cylinder 10 and removes the adhering impurities.
  • the contaminated cleaning fluid collects at the bottom of the housing 2 and over which the gradient flows in the floor, supported by the flow 17 generated by the nozzle 4, via the outlet opening 5 with the return line 6, the contaminated cleaning fluid into the sedimentation device 7.
  • the drainage can take place by suction of the contaminated cleaning fluid are supported.
  • the contaminated cleaning fluid separates into at least two components (phases) under the influence of gravity.
  • the first phase consists of dirty water 13 (suspended solids and water) and settles on the bottom of the sedimentation device.
  • the second phase consists of pre-cleaned cleaning fluid 12 (detergent).
  • the pre-cleaned cleaning fluid 12 is supplied to the nozzle 4 under pressure by means of the supply line 9.
  • the nozzle 4 generates a flow 17 at the bottom of the housing 2 with the pre-cleaned cleaning fluid and flushes the bottom and the drain opening 5 along the housing 2. Flushing with pre-cleaned cleaning fluid is preferably combined with suctioning off the contaminated cleaning fluid via the drain opening 5.
  • the supply of pre-cleaned cleaning fluid 12 preferably begins shortly before the actual cleaning operation and is maintained for a short time, for example 60 seconds, after the cleaning operation has ended. This prevents contaminated cleaning fluid from accumulating and possibly adhering to the housing base, and the cleaning effect when flushing is increased.
