Definitions
- the invention relates to a lining element for wall cladding of a thermal irradiation arrangement and to such an arrangement which has at least one high-power radiation source for radiation in the visible, near infrared (NIR) or ultraviolet (UV) region.
- NIR near infrared
- UV ultraviolet
- UV radiation having a significant active content in the near infrared (NIR), in particular in the wavelength range between 0.8 .mu.m and 1 , 5 microns, and so heated.
- NIR near infrared
- UV or visible radiation is also absorbed by many materials and causes corresponding thermal effects.
- UV radiation is used for processing purposes, for example for drying the printing ink on high-speed print image carriers or for curing special paint formulations, in addition to or primarily prior to its thermal action, its crosslinking-initializing effect is of particular importance for certain polymers.
- counter-reflectors are often provided on the side of the object to be processed facing away from the radiation source and / or side reflectors, if necessary for the formation of a substantially closed radiation space.
- a rapidly conveyed processing object such as a paper web, a plastic film, a metal strip, an elastomer profile or preforms or the like. This results in substantial improvements in the treated product and in the process control.
- the reflectors form walls of an irradiation zone or a radiation space.
- Corresponding arrangements can be found, for example, in the patents DE 198 07 643 C2 and DE 198 57 044 C2 and in the published patent applications DE 100 51 641 A1 and DE 100 51 642 A1 of the applicant.
- WO 2006/07 2282 A1 finally describes the special lining of a radiation room with tile-like reflector plates with reflective front and radiating back.
- the unpublished German patent application 10 2006 029 252.9 of the applicant describes a wall cladding which has been further improved under certain aspects, and moreover also a specially shaped irradiation chamber.
- the invention is therefore based on the object of providing a further improved lining element of the type mentioned and a correspondingly improved irradiation arrangement in which, in particular for irradiation goods, which can cause contamination of the lining to a considerable extent, the average life of the lining elements can be increased and thus further savings on maintenance time and costs are possible.
- the lining element is designed as a composite element of the solid support with high heat capacity and a first surface forming, cohesively connected to the carrier cover of a metal foil or a thin metal sheet or a metallized glass or quartz glass layer ,
- This structure is Although manufacturing technology relatively complex, but allows in almost ideal manner, the combination of a surface with the highest reflectivity with a material and manufacturing cost-effective carrier.
- the carrier can be formed as a rolled or extruded part of a metal with high thermal conductivity, in particular aluminum or an aluminum alloy.
- the carrier is designed as a molded sintered part made of a ceramic, with high thermal conductivity.
- the cover may consist of a sheet-like composite material which has a coating with a reflectance of 97.5% or more on UV and / or NIR radiation on a metal sheet supporting layer.
- the free surface of the sheet-like composite material has a transparent oxide or glassy corrosion protection layer.
- the sheet metal supporting layer of the composite material may be made of aluminum or an aluminum alloy.
- the cover is melted onto the carrier or soldered over its entire surface with a high-temperature solder.
- the cover may be melted onto the carrier or soldered over its entire surface with a high-temperature solder.
- the lining element is not subject to any particular restrictions, but this can be largely matched to the desired shape of the irradiation room and the subdivision of the wall into individual lining elements. It is understood that a design in the form of a plate with as simple as possible, incorporated fasteners (groove, tongue / groove, etc.) cost advantage.
- the carrier may well be shaped such that the first surface, in particular partially elliptical, parabolic or W-like, is curved.
- one of the (outer) walls of the irradiation chamber may be provided with a wire construction, and the fastening means of the carrier then have a corresponding profiling for snapping or latching the lining element thereon.
- Another possibility consists in the provision of substantially parallel rails as a supporting structure and corresponding profiling of the lining element back for pushing or possibly also clipping on these rails, especially for producing a compound of tongue and groove type.
- Figure 1 is a schematic representation of a wall section of an irradiation arrangement according to the invention with a fastening device and a lining element.
- Fig. 3 is a schematic cross-sectional view of a lining element used in the arrangement of FIGS. 1 and 2.
- FIG. 1 shows a section of a wall 11 of an irradiation arrangement 10 according to the invention, to which a lining element 13 (shown here partially cut open) is fastened via a fastening device 12.
- the wall 11 is designed as a solid support structure for the process or radiation space.
- Channels 14 serve to convey cooling fluid, such as water, air or a thermal oil.
- the simplest and therefore most cost-effective solution is water cooling with water at low pressure. If the temperature of the wall 11 in Operating the system above 100 ° C, however, the cooling by water at high pressure, air or oil is also possible.
- the fastening device 12 is designed as a quick-release holder made of spring wire.
- the wire forms two centrally fixed frame or legs 12.1, 12.2.
- the connection with the wall is realized as a riveted joint 15.
- Various deviations from the embodiment of the fastening device 12 shown in FIG. 1 are conceivable.
- the two frames of spring wire instead of the two frames of spring wire only one frame or there may be more than two frames. These may be attached to the wall via two or more connections; instead of rivets, as shown in Fig. 1, also screw or other types of connections can be used.
- the lining element 13 is clamped onto the spring wire frame 12.1, 12.2 of the fastening device 12. It has to advantageous on one side of a receiving area 16 for the spring wire.
- the distance between the back of the module 14-1 and the surface of the wall 11 is about 2 - 5 millimeters.
- the clamped element 13 can be removed either without tools or with a simple tool (eg. A screwdriver) with little expenditure of time.
- FIG. 2 shows an irradiation arrangement 10 according to the invention.
- Wall sections 11 form an entrance of a radiation tunnel 17.
- the wall sections 11 of the radiation space 17 are lined with the lining elements 13 modular. Excluded is a bridge or an irradiation area 18, which is formed in the operation of the tunnel 17 by a non-drawn quartz glass, below which a plurality of NIR emitters 19 which radiate NIR radiation into the tunnel 17.
- irradiation material is passed through the radiation tunnel 17 by means of a conveyor belt not shown.
- some of the lining elements 13 are each provided with a contact protection 20. hen. This is advantageous instead of attached to the wall of the modules, for example by screwing to allow easy and quick replacement of these modules.
- Fig. 3 shows a schematic cross-sectional view of the structure of a suitably usable in the prescribed arrangement lining element 13 of a solid aluminum or ceramic support 13.1 and a fixed thereto and with high thermal conductivity at the transition cover 13.2.
- the cover 13.2 consists of a thin AL sheet 13a with high rolling quality, on which a superpure AL layer 13b is formed by vacuum deposition and subsequently a highly transparent SiO 2 layer 13c is formed on the reflection layer 13b.
- the connection to the carrier 13.1 is formed by a thermally highly conductive and conductive adhesive 13d and on the back of the carrier 13.1 is formed by anodizing the same a firmly adhering black and in use state back radiating layer 13e.
- a groove 13f on the rear side of the carrier 13.1 makes it possible for the lining element 13 to be pushed onto a (not shown) support rail of an irradiation chamber and held securely there in use.
- the radiation capacity of the back of the lining element can be used by blackening to adjust the temperature. If fastening devices such as the wire-shaped holders shown in FIGS. 1 and 2 are used, the heat conduction through the fastening device can be neglected with regard to the thermal equilibrium of the lining element (however, in addition to the heat radiation, there will always be low heat removal by convection).
- the solvents are thus not or only to a small extent precipitated on the lining elements lining the wall, but remain in gaseous form in the interior of the radiation space and can be extracted by a ventilation system.
- a ventilation system so that the pollution of the reflective system components is substantially reduced. Cleaning work falls in a correspondingly smaller extent. The treatment still occurring pollution is also much easier, since the dirty modules of the lining if necessary. Not cleaned and polished, but only replaced. Overall, therefore, the downtime shortened significantly. Removed modules can, however, be cleaned according to the type and degree of contamination, if necessary also outside the plant, and later reused.
- An irradiation arrangement according to the invention is advantageously usable, for example, in drying installations for drying and / or curing paints.
- a paint coating applied to a substrate is exposed to radiation in the infrared range and / or in the UV range.
- the reflectivity of the lining element of the invention can be adapted to the specific wavelength ranges used, so that the element assumes a temperature above the boiling point of solvents evaporating from the paint during operation of the system.
- An irradiation arrangement according to the invention can furthermore advantageously be used in radiation drying installations for drying paints, printing inks, glazes, oils or the like into substances to be permanently introduced into a substrate.
- the substrate is exposed to radiation which penetrates into the substrate to a certain depth. This causes a drying or hardening of the introduced substances, whereby solvents can be released from the color and / or constituents of the substrate itself.
- a lining of the radiation space of such a system with the lining element according to the invention also leads here to a significantly reduced contamination and thus lower standstill.
