Definitions

  • the invention relates to a continuously operating infrared drying plant, in particular for drying water-miscible lacquers on glass objects. Moreover, the invention relates to a method for operating such a drying plant. Moreover, the invention relates to a painting system with such a drying plant.
  • circulating air-based thermal drying systems 1 are mostly used, see Fig. 1 , These systems are either gas heated or electrically heated. They usually have a chamber 4 provided with an inlet opening 2 and an outlet opening 3, through which the material to be dried is moved on loop paths 5.
  • the chamber 4 is divided into a heating zone 6 and a cooling zone 7 downstream of the heating zone 6.
  • the heating zone 6 is preceded by a discharge zone 8.
  • the material to be dried is heated by means of the heated circulating air.
  • the supply of circulating air via a tunnel system, which is usually installed in the ceiling area of the heating zone 6.
  • the recirculation of the circulating air via a tunnel system at the bottom of the heating zone 6.
  • the Ablpropzone 8 serves to withdraw the paint before entering the heating zone 6 solvent and water, so that they are not included in the drying of the top coat of paint.
  • the Ablpropzone enters the material to be dried immediately after leaving the Paint injection reservoir 9.
  • the transported on a conveyor chain in a continuous web is removed after leaving the chamber 4 in a placement area 10. Subsequently, the conveyor chain is again equipped with to be doped Good before it enters the paint spray device 9.
  • the repeated redirecting the material to be dried within the chamber 4 adversely affects the drying process.
  • the material to be heated cools in the reversal regions of the webs 5 in the heating zone 6 unintentionally, while the goods to be cooled in the reversal regions of the webs 5 in the cooling zone 7 unwanted rewarm several times.
  • the in the FIGS. 2 and 3 shown heating and cooling curves reflect this behavior.
  • a fundamental disadvantage in the use of such recirculating air dryer 1 it is also that the heat energy can not be targeted in the material to be dried can be introduced.
  • the heating curve is, if at all possible, only badly adjustable or adjustable. In particular, an adjustment of the holding time is usually not possible. If the hold time is adjustable, this setting is only very inaccurate possible.
  • the cooling is not controllable, so that the products have different temperatures after passing through the dryer.
  • the drying behavior of such a system is tuned in many cases only to a single product to be dried and thus unsatisfactory for all other products.
  • An adaptation of the dryer to different goods to be dried is either not possible or associated with a very high cost.
  • Such a conventional, circulating air-based thermal drying system is, for example, in DE 101 28 794 A1 described.
  • infrared drying systems are much better.
  • such systems which are also already known from the prior art, are provided in the heating zone infrared radiators for the targeted introduction of heat energy in the material to be dried or to achieve the required temperature in paint or paint carrier.
  • the heat supply depends strongly on the position of the infrared radiator, so that the material to be dried is usually not heated evenly.
  • the heat energy introduced there by means of the infrared radiator in the material to be dried is moved out of the heating zone due to the mass flow of the paint carrier through the dryer.
  • This undesirable heat transport which leads to an expansion or displacement of the heating zone, adversely affects the drying process, since the heating behavior of the material to be dried changes in an unpredictable manner.
  • a precise, tailored to the concrete material to be dried drying is therefore not possible even with such systems.
  • EP 1 681 102 A1 describes a drying process for paint layers, wherein in the Ablrangezone an infrared drying is provided. So that the paint surface is not is completely closed, a simultaneous air cooling is provided, which should keep the paint surfaces open, so that volatile components can be removed.
  • An object of the present invention is to improve the drying process in an infrared drying plant.
  • An essential idea of the invention is to provide an infrared drying plant with a scooping air device for generating an air mass flow, wherein the air mass flow runs counter to the dry matter mass flow.
  • scoop air eliminates various disadvantages of conventional infrared drying systems. In particular, this prevents the heat energy from migrating out of the heating zone into the cooling zone together with the mass flow of the material to be dried. Instead, the heat energy remains completely or in large part at the desired position in the heating zone, whereby an optimal heating process can be ensured.
  • the material to be dried has a high mass, ie it is, for example, very thick-walled glass objects, a large amount of heat energy is transported from the heating zone in the direction of the cooling zone due to the movement of the material to be dried through the channel.
  • an automatic control of the flow of air as a function of this heat transfer, the migration of heat towards the cooling zone, a correspondingly strong trained Schub Kunststoffstrom is opposed, which has the consequence that the heating zone held at its original, defined according to the material to be dried, optimal position becomes.
  • the scarfing air heated up in the heating zone also heats the scavenging zone at the same time.
  • An additional heat supply for the Ablluminazone may thus be omitted, depending on the system.
  • the items to be dried are good of low mass, eg. B. thin-walled glass objects, it is transported with the mass transport correspondingly less heat energy from the heating zone in the direction of the cooling zone.
  • the mass transport correspondingly less heat energy from the heating zone in the direction of the cooling zone.
  • the channel of the dryer according to the invention has, starting at the inlet opening in the passage direction seen one behind the other arranged on a Ablluminazone, a heating zone and a cooling zone.
  • the material to be dried is moved through, wherein it enters through an inlet opening into the channel and leaves the channel again through an outlet opening.
  • the movement of the material through the channel preferably takes place in one lane.
  • the objects to be dried are moved through the channel only one after the other and not side by side. This ensures that a uniform energy input occurs. This ensures a uniform final cross-linking and is especially important for products with uneven mass distribution.
  • drying of paint is understood not only drying in the conventional sense, but also the curing of the paint. This means that after passing through the drying plant all necessary chemical reactions should be completed.
  • the scarf air at any point behind the heating zone, as seen in the passage direction is introduced into the channel.
  • the air mass flow passes through the entire channel.
  • the intake of fresh air takes place at the channel outlet or in the immediate vicinity of the channel outlet and the outlet air outlet at the channel inlet or in the immediate vicinity of the channel inlet.
  • the cooling function of the scarf air in the cooling zone can act optimally, as well as the heating function of the scarf air in the heating zone and optionally in the Abl zone.
  • the exiting scoop air is returned to the intake of the blowing air. This can be done at the same time a cleaning and / or cooling of the air masses.
  • a cleaning and / or cooling of the air masses When controlling the temperature of the incoming scoop air, make sure that no tension or cooling cracks occur in the material to be dried.
  • a mixture of the recycled air masses with externally supplied air for example by means of a separate blower.
  • the flow of air which penetrates the channel in opposition to the mass flow, provided that it completely penetrates the heating zone, also prevents the ingress of moisture from the discharge zone into the heating zone. This is advantageous if it is to be prevented that moisture from the direction of the exhaust zone coming penetrates into the heating zone. If a minimum amount of moisture is required for the paint drying, this is preferably provided exclusively via the air mass flow to be introduced into the cooling zone. Thus, the amount of moisture can be controlled very easily and reliably.
  • the humidity of the scoop air moves in a predetermined range of values
  • Moistening is particularly advantageous when the paints to be dried are water-miscible paints comprising hydrophilic silanes.
  • an ultrasonic moisture fogging may occur be used to ensure the moisture content required in the cooling zone for a final cross-linking of the lacquer layer.
  • the drying or moistening of the scarf air can also be effected by other means which are known to the person skilled in the art and therefore need not be further explained at this point.
  • the channel in a modular manner, specifically such that at least the heating zone, but preferably also the exhaust zone and / or the cooling zone, consists of a number of channel segments.
  • the standardized segments which are preferably identical in their external form, can be lined up as desired and designed according to their function, that is to say they are provided with infrared radiators, for example in the case of a heating zone channel segment. It is advantageous if the cross-section of the tunnel-shaped channel is as small as possible, so that the energy emitted by the infrared radiators energy can be used efficiently, especially if the channel is well insulated.
  • a small cross section of the channel is not only advantageous because then the distance between the material to be dried and the infrared radiators can be kept low. With the smallest possible channel cross-section and thus a small volume of dryer less scarf air is needed, which minimizes the cost and the cost of Schubluftrgna.
  • the channel is open in a preferred embodiment of the invention downwards and stands on any expandable transport console, which is used to transport the goods to be dried by the drying plant.
  • Each channel segment has flange surfaces or similar fasteners.
  • the individual segments are isolated according to their function as a heating zone segment, Ablpassensegment or cooling zone segment, wherein the corresponding insulation is preferably disposed between an outer and an inner layer of the channel segment. Due to the small compared to the large chambers of conventional drying plant system volume dryer several inventive dryer can be operated in parallel without much effort, without the need for very large spaces.
  • All segments have standardized function openings, which serve as supply air or exhaust air openings or alternatively for the optional installation of functional elements. These may be, for example, infrared radiators, transducers or special elements such. B. elements for moistening the material to be dried.
  • the heating zone it is provided to temporarily increase the heat energy provided in the heating zone. This is preferably done by additionally provided infrared radiators are switched on.
  • the connection is preferably always when there is a short-term loss of energy in the material to be dried, which flows to the good heat energy applied through the paint into the interior of the object and for this reason the paint temperature is too low.
  • the performance of the heating zone can be arbitrarily adapted to the requirements of the good to be dried by the number of infrared radiators per channel segment can be increased.
  • the length of the heating zone can be adapted to the requirements by increasing the number of heating zone segments used.
  • a very significant advantage of the drying system according to the invention is that the duration of the holding time can be maintained very accurately. Since not only the position of the heating zone, but also their length can be set and precisely adjusted, the holding time can be precisely maintained.
  • the holding time can also be changed by adjusting the number of infrared radiators or the number of Schublufttexs just as precisely, so that the optimal hold time can be used for each paint system used. Overbake of the varnish due to an excessively long hold time can therefore be ruled out as well as a lack of final crosslinking due to a too short hold time.
  • the present invention it is therefore possible to respond flexibly to the most diverse paint systems with a single drying system and still achieve optimal drying in each case. This can be achieved in the simplest case, without the modular drying system must be rebuilt. If necessary, the number of channel segments used can also be varied in a particularly simple manner.
  • a drying system for any paint can be put together.
  • the system can be extended at any time and can therefore also be used for drying tasks that are currently not foreseeable. By parallel operation of several dryers, the drying capacity can be easily increased. Another advantage is that defective segments at any time without great effort can be exchanged. Development costs are incurred only once.
  • the material to be dried after leaving the discharge zone, reaches the heating zone heated to a certain final temperature.
  • the course of the heating curve is thus dependent solely on the mass of the goods.
  • the present invention allows for a relatively short and effective exhaust zone a longer, more targeted and a controllable heating process is followed, with the help of which it is possible to comply exactly with the drying specifications of the binder and additive manufacturers.
  • the invention provides the opportunity to leave the material to be dried in the heating zone until all chemical reactions are complete, without a "overburning" and a related quality defect must be accepted.
  • the drying system can be extended at a later date by additional channel segments with which new technologies can be implemented in the system. For example, it is possible to replace the infrared radiators used in the present case with radiators based on a different technology. Already today, the infrared radiators can be replaced by ultraviolet radiators, without, as the skilled artisan recognizes, something to the basic principle of the invention changes. In this case, the drying system could be used for Drying of paints are used, which contain UV-reactive substances in the paint formulation.
