Definitions

  • the invention relates to a method for supplying paint lines with paint material according to the preamble of the main claim.
  • a blocking tank is switched on, which is optionally put under a pressure that corresponds to the pressure of the pressure container or is depressurized and thus corresponds to the pressure in the collecting container.
  • the invention has for its object to provide a method for supplying paint lines with paint material, in which a substantially constant pressure can be maintained in the system, the intermediate cleaning of the line and container is easy and at the same time it is ensured that the volume flow is as constant as possible is available.
  • the invention further relates to a method for supplying painting lines, in particular the spraying points in spray booths with coating material, a pipe section being used for supplying the coating spraying points which have a pressure vessel at both ends, the pressure vessel with a pressure gas via a controller in this way be applied that the paint material is reversely conveyed through the pipeline.
  • the invention is also based on the object of avoiding such blockages and flow resistances in a procedure according to US-A-2542855.
  • This object of the invention is achieved in that a pipe pig is used in the pipeline, which is driven reversibly with the paint material through the pipe and an intermittently operated holding device for the pipe pig is provided at the locations between the hose connections of a spraying point, which is the pipe pig temporarily stops, so that paint material can flow through the hose connections to the spray gun.
  • a ring line system 1 which may consist essentially of a tube in which the paint material is circulated with a circulation pump 2.
  • the starting point and end point of this ring line system 1 is a pressure vessel 3, from which the circulation pump 2 draws paint material and feeds it back in.
  • a level controller for the amount of paint in the pressure vessel 3 ensures that fresh paint material is fed to the printing system via an unpressurized paint batch container 5 and a second but smaller pump 6. These Pump 6 has to overcome the full static pressure jump, but the coating material is only conveyed once with this pump.
  • the pipe length of this system concept would correspond to the length of the previous systems.
  • a major advantage of this embodiment is that the paint material is circulated with a significantly reduced shear stress intensity.
  • the pre-pressure at the injection points 4 can be kept constant better. Nitrogen can be used as the compressed gas. Previous oxidative influences on the paint material have been eliminated.
  • the pressure diagram for this system is shown in FIG. 5.
  • the paint batch container 5 is depressurized, i. H. here there is pressure a.
  • the pressure is then raised to the value c via the piston pump 6.
  • the pressure points for the spray guns are arranged and in this area the pressure is adjusted to the spray pressure h via material pressure regulator 7 according to FIG. 1.
  • Fig. 2 shows a system with pressure vessels arranged at both ends of the pressure vessel.
  • a pipe section L2 which has no separate return, so that only half the pipe length compared to the system shown in Fig. 1 is required.
  • two pressure vessels B2 and B3 are provided in this system, which are arranged at the two ends of the pipe section L2.
  • the coating material is reversely conveyed back and forth in the pipe section L2 under increased static pressure, which is generated by a gas pressure cushion above the respective liquid level in the pressure vessels B2 and B3.
  • the gas pressure in the container B2 is set somewhat higher than the gas pressure in the pressure container B3 and then vice versa.
  • the pressure switching cycles are controlled by level regulators in the two pressure vessels in such a way that a gas breakdown in the pipe section L2 is avoided with certainty.
  • the volumes of the containers B2 and B3 should be one or two times larger than the actual pipe volume of the section L2, so that the material in the pipe can be fully exchanged and mixed back after each reversing cycle.
  • the reversing cycle does not only flow through the pipeline in one direction, but alternately in both directions. This prevents deposits of particles to an even greater extent on the pipe wall and in particular on flange points and similar uneven transitions. Furthermore, the start-up flows that are constantly generated during reversing sometimes create turbulent flow behavior, which prevents particles from settling to a large extent. This makes it possible to switch to lower average flow velocities of, for example, less than 0.3 m / s. Furthermore, there is the possibility of not reversing constantly, but at intervals with standstill intervals.
  • K designates a compressor which compresses the compressed gas with the pressure stage h from the pressure vessel B4 into the pressure vessel B5 to the pressure stage i.
  • 3-way valves V2 and V3 are drawn, which are controlled by the level regulators of the pressure vessels B2 and B3, these 3-way valves the pressure vessels B2 and B3 alternating with the higher gas pressure i from the pressure vessel B4 or the lower gas pressure Actuate h from pressure vessel B5.
  • the effective pressure difference (pressure i minus pressure h) is responsible for the mean flow velocity in line L2, while the pressure h corresponds to the lowest static pressure in the supply system, which acts as a constant pre-pressure at the spray points (see Fig. 6).
  • the compressor K with the associated pressurized gas containers B4 and B5 can supply several paint supply systems simultaneously and therefore only needs to be installed once. Since the compressed gas is circulated, the gas losses as well as the solvent losses are low and it is recommended to use nitrogen as the gas.
  • Nitrogen increases the operational safety of pressure vessels B2 and B3 and prevents oxidative changes to the paint material.
  • the level regulators of the pressure vessels B2 and B3 also ensure that the paint material used during spraying from the paint preparation tank B1 in the atmospheric pressure a prevails via the pump P in sufficient quantity as fresh paint is fed to the pressure system via the line L1.
  • V1 in FIG. 2 The material pressure regulators that may be required are designated V1 in FIG. 2.
  • solenoid valves V111 to V 114 are inserted between the branch lines and hose connections d 111 to d 142 . These solenoid valves are either completely open or completely closed at times. There is then no throttling of the paint flow. However, only one solenoid valve may be temporarily closed. A timer can control which solenoid valve is closed, when and for how long. It is irrelevant whether the paint flow in the pendulum line is from right to left or vice versa. It is essential that when the solenoid valve is closed, the differential pressure in the pressure vessels B12 and B13 initiates a paint flow in the branch line to the spray gun. It is sufficient if this flow is generated at time intervals for a short time at each spray point.
  • V 411 pressure reducing valves are attached directly to the spray gun.
  • the paint supply to the spray gun is ensured in all cases, regardless of whether the corresponding solenoid valve is closed or open. With the timer, the intervals and the closing times of the solenoid valves can be individually adjusted to the paint material.
  • FIG. 4 two possible controls for a so-called pipe pig M are shown.
  • the pipe pig is controlled by a mechanical tappet arrangement 10, while in the other arrangement a magnetic blocking device is provided for the pipe pig M having an iron core.
  • the newt has the task of keeping the pendulum line free of deposits and deposits. He can do this at very low flow velocities and must do this with reversing motion.
  • the pig will replace the solenoid valves at the same time. He can do this if he is temporarily stopped between the stub lines to the spray guns and thereby blocks the main flow direction in the pendulum line, so that the paint flow must take place via the stub line.
  • the pipe pig can be stopped and temporarily held at certain positions on the pendulum line, for example by means of an induction coil or a mechanical device.
