Definitions

  • the present invention relates to an apparatus for use in a decoating basin, a decoating basin and a decoating plant.
  • an apparatus for metered delivery of a fluid to a solution of a stripping tank comprising: a metering tube for conducting the fluid, the metering tube having at least one passage formed such that the fluid metered the solution of the decoating pool can be fed.
  • the supply of a fluid into the solution of a decoating basin can lead to turbulences in particular at the workpieces to be stripped.
  • the stripping of entire layer pieces can be facilitated by the fact that they are mechanically moved or swirled by an ascending fluid flow.
  • fluid introduced into the solution of the decoating basin may e.g. Air, water or other suitable gases or liquids are used.
  • a decoating basin comprising: a device according to any one of claims 1 to 9.
  • a stripping process can be carried out in a shorter period of time since not only does a chemical or electrolytic stripping process take place, but the stripping process also mechanically supports the stripping process.
  • a decoating system comprising a decoating basin according to one of claims 10 to 13 is provided.
  • an apparatus wherein the metering tube is arranged in the vicinity of the bottom of the decoating basin.
  • the metering tubes according to the invention can be supplied with a gas, eg air.
  • a gas eg air.
  • Dosierrrohre near the bottom is ensured in this case, that overlying workpieces are washed by the rising air bubbles, whereby the decoating process is promoted.
  • the workpieces could also be arranged above the metering tubes on a perforated plate, for example.
  • a device wherein the metering tube is formed meander-shaped.
  • a meandering design of the metering tubes (or only one metering tube) e.g. in only one level leads to a very compact and therefore space-saving arrangement within a decoating basin.
  • a device wherein at one end of the metering tube, an inlet and at the other end of the metering tube, a drain for the fluid is arranged.
  • an apparatus comprising: a first metering tube having a first port for supplying a first fluid and a second metering tube having a second port for supplying a second fluid.
  • a device wherein the first fluid is different from the second fluid.
  • the device according to the invention can be provided with at least two metering tubes, wherein the first metering tube and the second metering tube can be fed with different fluids, whereby depending on the area of the de-coating tank the workpieces to be stripped can be stirred around with different fluids.
  • the first metering tube and the second metering tube can be fed with different fluids, whereby depending on the area of the de-coating tank the workpieces to be stripped can be stirred around with different fluids.
  • a device wherein the first connection and the second connection can be supplied by a third connection.
  • a device wherein the first metering tube is arranged parallel to the second metering tube.
  • a parallel arrangement of the metering leads to a compact design and optimum utilization of the existing surface in order to achieve the greatest possible turbulence of the solution in the stripping tank can.
  • a device wherein the device has a plurality of metering tubes, wherein the metering tubes are arranged like a stamen.
  • a star-shaped arrangement of metering tubes results in a simplified supply of a plurality of metering tubes, e.g. at the delivery point and a supply of a fluid of the largest possible area of the solution in the stripping tank.
  • a decoating basin comprising: a tube for adjusting the temperature of the solution of the decoating basin to a required process temperature.
  • a tube for adjusting the operating temperature in the solution allows the exact adjustment of the operating parameter temperature to e.g. a work instruction for removing a specific layer of workpieces.
  • the tube is preferably needed for cooling the solution, which is why it can also be referred to as a cooling tube.
  • a decoating basin wherein the tube is formed meander-shaped.
  • a meandering arrangement of the cooling tube represents optimal utilization of a limited area within a decoating basin.
  • a stripping tank is provided, wherein the pipe is disposed at the same level of the stripping tank as the metering pipe, the metering pipe being disposed between two portions of the pipe.
  • cooling and metering tubes can be arranged in a single plane, whereby the space required for the cooling and metering tubes can be minimized.
  • a decoader comprising: an emergency catcher and a water recooler.
  • the invention can be considered to promote an electrolytic or chemical stripping process of surfaces of coated workpieces by supplying a fluid.
  • a fluid for example, air can be used as the fluid, wherein due to the air bubbles in the solution of the decoating basin, mechanical influences on the surface to be detached occur, which can be detached from the workpiece faster and more thoroughly.
  • Fig. 1 shows a decoating system, which is constructed as a plug and play system.
  • the stripping plant comprises a status display 102, which signals the status of the currently running process by illuminating different color elements.
  • the stripping plant further has a control cabinet 101 for process control and a stripping basin 103 into which the workpieces to be stripped can be introduced.
  • the (chemical or electrolytic) solution of the decoating basin 103 can be discharged via the valve 106 into an emergency container 107 in an emergency.
  • a water recooler 104 serves to adapt the operating temperature of the solution of the stripping tank 103 to the required process temperature.
  • the stripping plant comprises a computer 108 which serves to connect to a company network, an intranet or the Internet.
  • Fig. 2 shows the front panel 202 of the cabinet with displays for power and voltage, and a voltage selector switch 203, a potentiometer and an alarm reset switch 204, the switches cooling on / off and circulation pump on / off 205, a temperature display 206, a switch compressed air on / from 207 and a main switch 208.
  • Fig. 3 shows a plan view of the stripping tank with tubes 301 to adjust the operating temperature to the required process temperature.
  • the tubes 301 may be meandered and disposed on one or more levels within the decoating basin.
  • Dosing tubes 302, 306 for supplying a fluid, eg air, can be arranged on the same or another level within the decoating basin.
  • the metering tubes 302, 306 have passages and can metered out the guided in the interior of the metering tubes 302, 306 fluid to the solution that is currently present in the stripping tank.
  • the discharged fluid leads to turbulence on the surface of the workpieces to be stripped, whereby a Abplätterm the layer to be removed can be accelerated.
  • a single metering tube can be arranged, which is arranged, for example meandering.
  • two, three, four, or any plurality of metering tubes 302, 306 may be disposed in the stripping tank. At least two metering tubes can emanate stemenformig from a common point, the common point are used as a common supply point can.
  • at least two metering tubes 302, 306 may be arranged parallel to each other. Individual metering tubes can form a closed circuit, whereby at least a portion of the fluid can be fed back. Alternatively, individual metering tubes 302, 306 may be formed as a "dead end" and may not include a return option.
  • the tubes 301 may form a closed circuit with an inlet 305 and a drain 303.
  • the tubes 301 typically do not have passages for dissolving the decoating basin.
  • Fig. 4 shows a plan view of the Ent harshungsbecken with tubes 401, which are arranged meandering meandering as cooling coils.
  • the tubes 401 serve to adapt the temperature of the solution of the decoating basin to the required process temperature. In the vast majority of cases, the tubes 401 serve to cool the solution of the decoating basin.
  • Fig. 5 shows tubes 501 for metered delivery of a fluid to the solution of the decoating basin.
  • the arrangement has a common connection 502 which serves to supply the individual tubes 501 with fluids.
  • the individual tubes 501 include no reflux
