Definitions

  • the invention relates to a radiation dryer in the chamber construction, which is typically equipped with so-called NIR radiator elements (which emit mainly in the near infrared radiation with high power density) and / or high-power UV lamps. It further relates to a drying system constructed with a plurality of radiation dryers of this type, as used in particular for drying coatings on a quasi-continuous good passing through quickly.
  • Radiation dryer and drying equipment of the type in question have been increasingly used in recent years in large-scale coil coating systems for paint coating and / or galvanization of windable sheet metal insert are used for the drying or crosslinking of paints or coatings on other substrates, for Drying of paper and cardboard or products thereof and of printed products, used for laminating of plastic films on various types of carriers and in other applications or are there in any case fundamentally applicable.
  • As an important field of application of structurally very similar systems with NIR radiator elements also stretch blow molding for the production of blown plastic bottles have proven in which the devices in question cause no drying, but a warming of the bottle preforms before the blowing step.
  • the following statements on the invention also apply to irradiation devices and systems of this type.
  • a recent development of the applicant which is described in DE 10 2006 004 574.1, is dedicated to the useful construction of a radiation dryer for the coil coating small series use.
  • the invention is therefore based on the object of providing an improved radiation dryer, which is characterized in particular by shortened maintenance and production interruption times when used in an irradiation material, which tends to pollute the radiators or reflectors.
  • the invention is based on the consideration that in the irradiation (especially drying) of certain irradiation due to the relatively high tendency to fouling of the emitters and reflectors in relatively short intervals cleaning or replacement is required and the spotlights and reflectors for this purpose as easily and quickly accessible should be made.
  • the invention therefore provides that, in the case of a radiation dryer having an irradiation material transport channel, a first one provided on its longitudinal sides Radiator block for maintenance purposes from the longitudinal side abgurbar or against the use position is pivotable, and that also mounted on the second longitudinal side second radiator block or counter reflector block is mounted and movable. After moving away or - preferably - unfolding the respective radiator or reflector block whose interior is freely accessible, and dirty radiator or reflector elements or sections are immediately recognizable as such and can be easily and quickly cleaned or replaced, and then the respective block quickly be transferred back to its position of use as well.
  • a radiation-permeable protective pane is provided between the irradiation material and the radiator elements and sometimes also between the irradiation material and counter-reflectors in order to intercept material emerging from the irradiation material and thus largely prevent workpiece-related contamination of the radiator or reflectors.
  • the invention is useful, because the spotlights and reflectors are also subject to pollution caused by the environment, because in view of the required high cooling capacity filtering the cooling air limits are set.
  • the corresponding protective disks are held in movable or pivotable protective disk elements. Their traversing or pivoting makes the respective discs easily and quickly accessible for cleaning or replacement.
  • an extendable arrangement of the protective cover (s) is also possible regardless of a Abgurkle or pivoting the associated radiator or reflector block and especially useful if workpiece-related contamination under certain conditions of use are far more serious than environmental pollution and therefore regular cleaning virtually only on the protective screen or the protective glasses must be performed.
  • both the first and the second as well as the second radiator block or the counter reflector block and at least one associated protective disk element are pivotable about an axis of rotation disposed on a longitudinal edge of the irradiation material transport channel.
  • the moving of the radiator or reflector block and optionally the protective screen (s), at least for smaller dryers can be done manually.
  • an electromotive, hydraulic, pneumatic or electromagnetic drive is provided for the removal or pivoting of the radiator block and / or reflector block.
  • Such a drive facilitates the work of the maintenance personnel and, with a view to the high operating temperatures and the considerable residual heat after switching off the dryer, also advantageous under occupational safety aspects.
  • each emitter or reflector block is provided with a cleaning device with its own drive (for example in the manner of rotating brushes), which cleans the radiator elements or reflectors mechanically and optionally under controlled discharge of cleaning fluid from corresponding nozzles or metering devices.
  • a cleaning device with its own drive for example in the manner of rotating brushes
  • Increased production costs of such a dryer are easily compensated in continuous use by a further reduction in maintenance time due to the possibility of large-scale cleaning of many radiator elements or reflector sections at the same time (and before complete cooling).
  • a high-end design can be characterized in that each lamp block is assigned a lamp test and change device for detecting the operability and optionally a degree of contamination and the robot-assisted replacement of non-functional or excessively contaminated lamp elements in response to the detection result.
  • this latter design can provide considerable time and cost advantages in use, because due to occupational safety requirements related waiting times can be significantly reduced before a replacement lamp with mechanical replacement of the radiator.
  • the radiation dryer is provided with a housing, in particular of metal profiles, which has the outer dimensions of a standard container and accommodates power control units for powering the radiators and optionally the or each drive.
  • Such a frame housing allows a rational pre-assembly of the radiation dryer in the factory and an equally efficient transport to the place of use and construction of this, with substantial elimination of costly packaging and Auspack suitsen and on-site completion completion- and installation services. As a result, the total cost of ownership can be significantly reduced.
  • the housing of metal profiles additionally accommodates fans and air filter elements for fan or intake air cooling of the radiators and / or of the irradiation material.
  • a container module of this type thus comprises in a manufacturing and operating highly effective arrangement all the essential components of an irradiation or drying device and offers time and cost advantages in the supply as well as during operation.
  • a larger drying plant can be constructed such that it has a plurality of radiation dryers according to one of the preceding claims with mutually vertically aligned irradiation material transport channels.
  • a particularly useful modular design results when each of the plurality of radiation dryers is housed in a housing and the outer dimensions of the housings are identical.

  • Fig. 2 is a sketch-like representation of a radiation dryer according to a second embodiment of the invention.
  • Fig. 3 is a sketch-like representation of a radiation dryer according to a third embodiment of the invention.
  • Fig. 1 shows schematically a radiation dryer 1, the Mitteilteil is formed by an irradiation material transport channel 3, which is traversed in the operating position of the dryer 1 in the vertical direction of a coated sheet 5.
  • a first or second shield element 7.1 or 7.2 and a first or second block radiator 9.1 or 9.2 with a plurality of NIR radiators 11 are pivotally connected to a rotation axis 13.
  • the pivoting movement of the protective disk elements and radiator blocks can be effected by hand, but it can also be an electric or hydraulic drive provided in the region of the axis of rotation 13, the driving force is transmitted by known per se to the respective protective disk element or the radiator block to these pivot.
  • Fig. 2 shows a further embodiment of the invention, a similarly constructed radiation dryer I 1 , in which also on each of the two longitudinal sides of the irradiation transport channel 3 per a protective screen element 7.1 'or 7.2' and a radiator block 9.1 'or 9.2' are arranged.
