Definitions

  • the present invention relates to a method for blowing off a liquid from an object wetted by the same, and an apparatus for carrying out the method.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, achieves the object of showing a method and an apparatus for blowing off a liquid from liquid from an object wetted by the same, in which compressed air jets are suddenly pulsed towards the object to be dried.
  • Figure 1 shows a schematically illustrated container 1, which is designed as a trough and e.g. is arranged in a street made up of various treatment containers of a system for the surface treatment of objects.
  • a system for the surface treatment of objects.
  • a system e.g. copper plating, chrome plating, silver plating, generally e.g.
  • Electroplating takes place, including electrolyte baths, but also baths for electroless processes such as Degreasing, pickling, phosphating and electroless metal deposition baths, but also baths for the anodic oxidation of aluminum, baths for dip painting can be present.
  • electrolyte baths but also baths for electroless processes such as Degreasing, pickling, phosphating and electroless metal deposition baths, but also baths for the anodic oxidation of aluminum, baths for dip painting can be present.
  • electroless processes such as Degreasing, pickling, phosphating and electroless metal deposition baths, but also bath
  • Air jet delivery devices are arranged along the two longitudinal walls of the container 1 and are constructed as follows. Each air jet delivery device has a side member 3, which in this example guided in the height direction of the container 1 is movable.
  • the drive is carried out by a motor 4 with adjustable speed, which is connected to the longitudinal beams 3 by means of chain sprockets 5 and chains 6, for example.
  • the drive transmission is designed in such a way that the side members can be moved in the same direction or in opposite directions to one another, ie if, for example, the side member 3 on the left moves from top to bottom, the side member 3 on the right simultaneously moves from bottom to top.
  • a number of tubes 7, which are closed on both sides, are connected to each longitudinal beam.
  • the tubes 7 are axially aligned with one another and run horizontally in this example.
  • the number of tubes 7 shown is purely for drawing reasons, for example. For example, 20 such tubes 7 may be present.
  • Each tube 7 has air outlet openings 8 which are arranged along a surface line of the respective tubes 7 in such a way that air jets emerging therefrom are directed at least approximately in a horizontal direction against the objects 2 to be treated.
  • the axial length of the tubes is approximately 150 mm, each tube containing 15 air outlet openings 8 at a mutual distance of 10 mm.
  • the compressed air is supplied via a compressor 9, which sucks in air from the environment.
  • the compressed air is fed from the compressor 9 to the tubes 7 via hose lines 10.
  • hose lines 10 For reasons of drawing, only one hose line 10 is shown in each case.
  • the compressed air supply to the individual tubes 7 is controlled by solenoid valves 11, such a solenoid valve 11 being assigned to each individual tube. These solenoid valves 11 are individually connected to a control device 13 via control lines 12, the function of which will be explained below.
  • a schematic Discharge pipe socket 14 is drawn, via which the liquid chipped off from the objects 2 is removed, possibly disposed of or also returned to a treatment stage of the system after possible treatment.
  • Each tube 7 is supplied with compressed air via a solenoid valve 11 assigned to it.
  • the solenoid valves 11 are controlled by a microprocessor in the control device 13.
  • the control device 13 can be used to set both the opening time of the solenoid valves and the frequency of opening and closing them depending on the application.
  • the pressure of the compressed air supplied is approximately 4 to 6 bar.
  • the solenoid valves 11 can be controlled by the control device 13 in such a way that not all tubes 7 are acted on simultaneously, but successively, in groups, etc. As an example, it is further stated that a compressed air blast occurs from the respective air outlet openings 8 every 0.4 seconds.
  • the frequency and duration of the compressed air pulses are determined in the control device 13 in accordance with empirical values, test runs that have been carried out temporarily, such that as soon as the residual amount of the liquid returns to the original area, the next compressed air pulse hits it in order to drive it away again.
  • the longitudinal beam 3 with the tubes 7 becomes extremely slow, e.g. 25 mm / second moved from top to bottom, so that two successive compressed air blows hit practically the same area, so that actually the successive areas of the impact points of the compressed air blasts overlap one another by a multiple, whereby the displacement of two successive impact areas in the vertical direction just for example Is 10 mm. While the nozzle assembly on the left in FIG. 1 moves downward along the objects, the one on the right moves upward.
  • Figure 2 shows purely schematically another application in a system for surface treatment.
  • the container 1 is again shown in a purely schematic representation.
  • the objects 2 to be dried and the longitudinal members 3 are drawn with the tubes 7.
  • a further nozzle assembly 16 for flushing water is arranged above each nozzle assembly 3, 7 for the compressed air, and in this embodiment there are nozzles for the smallest amounts of water with optimum dispersion.
  • This version is intended for use, for example, between an electrolyte bath and an economy flushing device.
  • the objects 2 lifted out of the electrolyte bath and inserted into the container 1 are initially exposed to the compressed air blasts in accordance with the above-mentioned procedure in order to knock off the electrolyte and to knock it back accordingly.
  • the electrolyte portion remaining on the objects in the form of a film dries out completely.
  • these objects are exposed to the water jets during the first or during a second pass, the amounts of water being selected such that the residual electrolyte does not dry out until it is inserted into the subsequent so-called economy rinse bath.
  • FIG. 3 shows, again in a purely schematic manner, a further embodiment, which is especially for drying, thus blowing off rinse water, for example. It is known that one goal of all types of drying is to achieve so-called spot-free drying, ie that no drops or traces of drops remain on the dried objects. Since even the smallest droplets are continuously destroyed and blown off by the air blasts, the above-mentioned goal can be achieved visually with the method according to the invention.
  • the container 1 also has a heat protection jacket on the side walls and on the bottom, one thermal insulation 17.
  • the space between the wall of the container 1 and the inner container is designed as a flow channel 19 which leads to the interior of the container 1.
  • the liquid on the surfaces of the objects 2 is knocked off again by the compressed air blasts, the drops fly or flow to the bottom of the container 1 in order to flow away through a drain connection (not shown).
  • a drain connection not shown.
  • One or more fans 21 are arranged in the bottom of the tub at a point between the same and the intermediate floor 20. These blowers 21 suck the moist air from the interior of the container 1 and convey it through drying devices 22. From these drying devices 22, the re-dried air flows, see arrow 23, into the space acting as a flow channel 19 between the inner container 18 and the outer wall of the container 1 to flow back through the passages 19 into the actual treatment room.
  • the moisture in the air which forms in the air in the container 1 is destroyed by the circuit described, which includes blowers 21 and drying devices 22, so that again and again dry air flows into the treatment room.
