Definitions

  • the invention relates to a device for applying coating media, e.g. Varnish on objects, consisting of varnishing chambers with an air flow that is forced to circulate in each varnishing chamber, and with a paint particle cutting device therein.
  • coating media e.g. Varnish on objects
  • the disadvantage here is that a regulating or at least one control device is required which determines the size of the partial air flow. Furthermore, it is necessary that for the coating of an object with several coating media, for example different colors, the chamber and spraying device must each be cleaned in a time-consuming manner. In addition, the chamber is only suitable for operation with the doors closed, since the highly enriched solvent vapors would otherwise escape; an arrangement of the chamber around a conveyor belt with the inlet and outlet open is therefore not possible.
  • the solution to the problem is that in the conveying direction of the objects in the painting chambers at least two ventilation zones are arranged next to each other and that the exhaust air from the previous ventilation zone, optionally the painting chamber, is supplied to the next ventilation zone or painting chamber via a paint particle separator and from the the last painting chamber with solvent up to a maximum amount of enriched exhaust air is fed to an incinerator.
  • the air is passed several times as circulating air through the painting and / or evaporation system, the exhaust air discharge being metered in such a way that the maximum solvent concentration reaches the permissible explosion safety concentration and the number of circulations in connection is selected with the respective zone width so that the air speed in the painting zones corresponds to a predetermined value and the explosion safety concentration limit is not exceeded in any area.
  • the device offers the advantageous possibility of directly combusting the exhaust air, which is highly enriched with solvent vapor, without preheating and of supplying the heat released to the drying process.
  • the amount of heat is so great that no further heating energy has to be supplied to a downstream drying system.
  • the color particle separation device is advantageously designed as a washing, filtering and drying device.
  • the constant removal and washing out of the paint mist from the air has the advantage on the one hand that there are hardly any flammable and difficult to remove deposits in the painting zone form of dye and that no mixing or overlapping of the colors occurs, particularly in the case of multiple or multi-color lacquering.
  • Safety circuits on the operating units and accesses enable safe operation and safe inspection of the systems.
  • a maintenance and operating station and the control device are advantageously designed to be explosion-proof and are arranged in the vicinity outside the systems. This has advantageously made it possible to significantly reduce the size of the coating chamber, which in turn has reduced the air throughput correspondingly compared to conventional chambers, which leads to correspondingly small circulating air and air cleaning systems.
  • 1 and 4 show exemplary embodiments for high-performance drum painting devices for one- and two-tone paintwork.
  • the size of the painting chambers has only been selected so that sporadic manipulation of the barrel spray chairs is possible.
  • the spray chairs are moved out of the paint chambers. This enables a high concentration of solvents in the circulating air of the painting chamber, since an operator does not have to be in this zone all the time.
  • This air is constantly filtered and washed out to prevent adhering paint particles from being blown into the paint chamber again no need to be cleaned in order not to lose quality on the painted surfaces.
  • the air is used five times, for example - there is a constant increase in temperature in order not to get any condensation of the moisture from the washed-out air on the barrel.
  • the solvents released in the painting area are absorbed into the air.
  • the air in the painting chamber has been entered in the last stage, it is led into the subsequent evaporation zone. There it continues to take up solvent, and it " is then fed from the furnace entrance lock as furnace fresh air to the furnace itself.
  • a horizontal one can also be selected.
  • dry filters are suitably used for the separation of color particles.
  • a painting chamber 10 and an evaporation system 30 is shown schematically in which the paint 11, barrels clocked according to production runs from left to right and from there directly leads into a drying oven.
  • the color particle separation device 12 a, b are washing towers which are arranged laterally offset to the passage of the barrels 11, as can be seen correspondingly from the horizontal section Fig. 3 line A-A.
  • the barrel 11 is surrounded on all sides from top to bottom by air currents V4a, b at a speed of approximately 0.5 m / s.
  • air currents V4a, b at a speed of approximately 0.5 m / s.
  • These air flows totaling 6000 m 1 / h are composed of the fresh air flow V3 of 2500 m 3 / h and a circulating air flow V2 of 3500 m 3 / h and are preheated by fans 21, 19 a via heating registers 22, 24 and via distribution filters 23, 25 supplied to the painting chamber 10.
  • a fresh air flow V1 with 1000 m 3 / h is additionally sucked in, since the throughput of the circulating air fan 19a is designed to be higher than that of the fresh air fan 21, so that no solvent vapors escape from the painting chamber 10.
  • the fresh air V3 is supplied on the side of the entrance.
  • the circulating air V2 coming from the entrance and the least loaded is drawn off in the entrance half of the chamber bottom 14.
  • a further air flow V5 of 5000 m '/ h is drawn off by the fan 19b and blown in accordance with the position of an adjustable throttle valve 31 in a partial flow V4 via a directional nozzle 34 from the evaporation chamber 30 through the passage opening to the painting chamber 10 pressed into the evaporation chamber in a second partial flow V7 of 3500 m '/ h.
  • the fan V32 draws off the exhaust air V8, which is highly enriched with solvent, and returns it according to the position of an adjustable distributor flap 33 in a partial stream V9 back into the evaporation chamber, which corresponds to the outlet stream V11, which is drawn off above the adjacent drying oven and in one another partial stream V10 of the evaporative incineration plant is supplied.
  • the circulating air streams V2, V5 are each guided through color particle separating devices, washing towers 12a, 12b.
  • the air passes through a grate 14 at the bottom of the chamber and sweeps over the sump 13 to the edge 13b of the wash tower, which is led to the level 13a of the sump surface, which is constantly held by a guard, causing the air to pass under the edge in a vortex, also called a water roller 15, passes into the tower 12a, b and the ink drops are washed out.
  • the water droplets absorbed by the air are then separated out on the baffle plates 16 and the perforated filter 17 and other filters.
  • the cleaned air will then heated so far above the dew point in the heating register 24 that no condensation occurs during the expansion in the following chamber pass.
  • the water in the sump 13 contains a coaling agent for paint mist. Further details are shown in FIG. 2, in which similarly equipped painting chambers are arranged one behind the other, the exhaust air from the first painting chamber being passed twice through the second painting chamber.
  • the reference numerals are chosen accordingly as in Fig. 1 and partially differentiated by attached letters.
  • Transport rails 40 on which the barrels roll from one spraying station to the other, run through the painting chambers 10a, b.
  • the barrels are stored on barrel chairs 41 and are driven by rollers 42, so that they are uniformly painted on all sides. In the present case, different colors are applied (in separate strips) in the two painting chambers. A sharp demarcation is made by stencils near the barrels (not shown) and the removal of the paint mist through the air.
  • the barrel chairs are mounted on rollers 62 with rollers 63 and can be moved out of the painting chambers for operating and maintenance purposes.
  • the barrels are set up and transferred to a roller conveyor 43 and transported in cycles through the evaporation system until they are conveyed into the drying oven by the conveyor belt 44
  • each fan 19a, b, c there is a ventilation flap 50 which can be controlled by a signal S19 and which, in the event that the system needs to be cleaned, is quick Allow venting in the exhaust pipes 51.
  • the position of the flaps is communicated to the control device 70 by detectors via signal line M50.
  • FIG. 3 there is a horizontal crack of the system of Fig. 2, from which it can be seen that the 4 washing towers 12a to d are alternately arranged laterally offset from the painting chambers and the transport route of the barrels.
  • the air duct 64 effect the assignment of the air emerging from the respective zone below to the associated wash tower.
  • safety doors 61 are attached, which can be opened from the inside at any time and from the outside only when the door lock is released by a control signal S61 of the control device 70.
  • all doors 61 are monitored by a closing control, the signal M61 of which is evaluated in the control device 70.
  • the control device is arranged in a cabinet next to the painting chambers between the maintenance areas of the spray chairs. It carries a control panel and control panel 73, from which the functions of the spray guns, the transport drives, the fans and flap drives are controlled and the alarm signals are received via the compressed air lines and cables 72.
  • the cabinet is airtight and supplied with compressed air from outside the safety zone 63 via a pressure regulator 74 and monitored by a pressure switch, so that no air containing solvent can enter it and explosions cannot be ignited.
  • the step-by-step roller conveyor 43 transfers 4 times in parallel to a correspondingly more slowly clocked roller lenbahn 45, on which extensive evaporation of the solvent takes place.
  • control device 70 is shown schematically. It is connected to the control display and control panel 73 and is clocked by a clock C. Furthermore, the control device receives the message signals Mx, which are emitted by the modules indicated by the associated reference symbols, and emits the control signals Sx, which are also identified by corresponding reference symbols.
  • spraying is stopped via signal SS and the vent is opened via signal S50.
  • the fans remain active via signals S19 and S32. If working for a specified safety time is determined via signals M19, M32, the door locks are released via signal S61.
  • the pressure regulator 74, the transport drives, the throttle valves 31, 33, and the water level 13a are controlled or regulated and monitored via the signals M74, MT, M31, M33, M13a and the associated signals S74, ST, S31, S33, S13a , which ensures a completely safe operation of the system.
