Abstract

The plant for drying painted substances (1), particularly of wood, comprises, viewed in the throughflow direction, a positioning section (2), a drying section (3) and a cooling section (4). Drying involves use of flameless heat panels, of which the heat emission can be varied by altering the surface temperature of the heat panels and/or the distance of the heat panels from the substances, combined with an adjusted air input of unheated air. - The positioning, drying and cooling times are adjusted in accordance with the capacity of a painting station and the layer thickness of the paint, together with the types of paint and wood.

Description

KRAV 1. Anlæg til tørring af lakerede emner (1), fortrinsvis af træ, der bevasges på et transportbånd (10) gennem en tørretunnel hvor der indblæses luft, kendetegnet ved, at anlægget, set i gennemløbsretningen, består en sætningsstrækning (2), hvor der sker en vedhæftning af lakken til emnet (1), derefter af en tørrestrækning (3), der kan bestå af en eller flere tørrezoner (3a -3f), og derefter af en kølestrækning (4), der kan bestå af en eller flere kølezoner (4a -4c), og at temperatur og luftskifte kan varieres i de enkelte zoner, og at tørringen sker ved hjælp af flammeløse varmepaneler (11), hvis varemeafgivelse kan varieres ved ændring af varemepanelets overfladetemperatur og/eller varmepanelets afstand fra emnet (1), og som er placeret over transportbåndet (10) og udsender en infrarød stråling, kombineret med et indstilleligt luftskifte af ikke opvarmet luft, og at kølingen i kølezonen foregår ved hjælp af luft, og at sætnings-, tørre- og køletiden afpasses efter kapaciteten af en lakeringsstation og efter laktykkelse, laktype og trætyper ved indstilling af varmepanelernes (11) varmeafgivelse kombineret med en ændring af luftskiftet og transportbåndets (10) hastighed, og at disse parametre reguleres fra en central styreenhed. 2. Anlæg ifølge krav 1, kendetegnet ved, at varmepanelerne (11) er udformet som plane elementer, der er ophængt over emnerne (1) i en indbyrdes afstand (a) og kan hæves og sænkes i forhold til emnerne (1) og svinges om en tap (12) således, at hældningen (v) i forhold til vandret kan varieres. 3. Anlæg ifølge krav 1, kendetegnet ved, at varemeafgivelsen i en tørrestrækning (3) med f.eks. fire tørrezoner øges gradvist i gennemløbsretningen ved at varmepanelerne (11) i de fire zoner har en overfladetemperatur på henholdsvis 180° C, 240° C, 290° C og 340° C. 4. Anlæg ifølge krav 1, kendetegnet ved, at transportbåndet (10) er udformet som en kæde, hvor de enkelte kædeled (18) består af et antal lameller (19) i indbyrdes afstand, så de tillader passage af varmestråler, og at der under transportbåndet er anbragt et eller flere spejlende flader (20), der kan reflektere varmestrålerne.REQUIREMENTS 1. Plant for drying lacquered workpieces (1), preferably of wood, which is irrigated on a conveyor belt (10) through a drying tunnel in which air is blown, characterized in that the system, in the direction of passage, consists of a stretching stretch (2), wherein the lacquer is adhered to the blank (1), then by a drying stretch (3) which may consist of one or more drying zones (3a-3f) and then by a cooling stretch (4) which may consist of one or more several cooling zones (4a-4c), and that the temperature and air exchange can be varied in the individual zones and that the drying is done by means of flameless heating panels (11), the delivery of which can be varied by changing the surface temperature of the heating panel and / or the heating panel's distance from the workpiece ( 1), which is located above the conveyor belt (10) and emits an infrared radiation, combined with an adjustable air exchange of non-heated air, and that the cooling in the cooling zone is carried out by means of air, and that the setting, drying and cooling it is adjusted to the capacity of a coating station and to lacquer thickness, lacquer type and wood types by adjusting the heat output of the heating panels (11) combined with a change in the air exchange and the speed of the conveyor belt (10) and that these parameters are controlled from a central control unit. Installation according to claim 1, characterized in that the heating panels (11) are formed as flat elements which are suspended over the parts (1) at a distance from one another (a) and can be raised and lowered relative to the parts (1) and pivoted. about a pin (12) such that the slope (v) relative to the horizontal can be varied. Installation according to claim 1, characterized in that the delivery of goods in a drying section (3) with e.g. four drying zones are gradually increased in the flow direction by the heating panels (11) in the four zones having a surface temperature of 180 ° C, 240 ° C, 290 ° C and 340 ° C, respectively. 4. An installation according to claim 1, characterized in that the conveyor belt ( 10) is designed as a chain in which the individual chain links (18) consist of a plurality of spacers (19) spaced apart to allow passage of heat rays and that one or more mirror surfaces (20) are arranged under the conveyor belt; that can reflect the heat rays.
