Definitions
- the invention relates to an oven for drying coated samples, in particular for the simulation of process conditions in a continuous furnace of a strip material coating system.
- COIL-COATING encompasses the large-scale Coating (varnishing) of strip material, i.e. sheet metal in different widths and materials. Doing so the sheet is painted in a downstream continuous furnace dried and rewound (COIL) to later at the processor, e.g. Manufacturer of kitchen appliances, Facade sheets etc., further processed (punched, be edged or deep drawn).
- COIL continuous furnace dried and rewound
- the invention is therefore based on the object To create (laboratory) furnace in which the in one Continuous furnace of a large-scale automatic belt material coating system prevailing conditions reliably have it simulated exactly.
- the furnace according to the invention is provided with a housing, in which there is a holding device for holding a painted sample is located that is a warm air flow is deployable, which on the bottom and / or hits the top of the sample. That airflow or these two air flows are from one Airflow generating device generated by it is one or more fans, in particular generate a circulating air flow. In There is a temperature control device for each air flow for heating the circulating air.
- the cradle is on one side of an air flow channel, that ends in the immediate vicinity of the sample. When the sample is supplied with warm air on both sides there are two such air flow channels, their Outlet ends facing each other and different Sides of the sample are arranged.
- each Air flow channel is an air flow equalization device, that of equalization the flow profile of the air flow.
- Any airflow equalization device points at least one unit from a multitude of adjoining Perforated plates that are corrugated in a zigzag shape, so that several perforations parallel to each other per perforated plate and surveys arise.
- zigzag Within the scope of this invention, both a Kink lines as well as wavy ones Perforated plate can be understood. Also perforated plate with Trapezoidal deformations are covered by this.
- the Perforated plates themselves extend in the direction of flow, so the air flow along the surfaces the perforated plates flows.
- the wells and Elevations of the perforated plates run in one acute angle to the flow direction, in particular between 30 ° and 60 °, preferably between 40 ° and 50 ° and in particular about 45 °.
- the particular one perforated plates are evenly provided with holes arranged alternately so that the depressions and surveys of adjacent contiguous Preferably cross perforated plates.
- each air flow equalization device several in the direction of flow successively arranged perforated plate units having adjacent units or packages of perforated plates rotated against each other are.
- the twisting of adjacent perforated plates is in particular 90 °.
- Perforated plate parallel within a perforated plate unit are aligned with each other, if several i.e. at least three units, every other unit aligned equally.
- the advantage of the furnace according to the invention is that that a re-enactment of the production conditions in on a relatively small scale.
- a painted sheet metal sample in size A4 or similar is opened with the help of a so-called sample drawer Furnace space introduced, the desired conditions, namely the air speed (fan speed) and the oven temperature.
- the oven air flows against the sample vertically from below and from above and temper them homogeneously over the entire surface.
- the sample is either determined according to a Time or after reaching the actual end temperature of the sheet in the CC system in the CC laboratory furnace with the help of a special thermocouple measured on the unpainted underside of the sample is extended.
- the extension and retraction can from Hand, after a signal sounds, or automatically (Pneumatic).
- Every conventional convection oven is characterized by its laminar flow pattern, which in the transient area, before reaching the oven temperature, one even temperature distribution on the sample plate impossible.
- the invention is based on the decomposition of the laminar Flow profile in a forced air oven to an air flow of the smallest partial flows of the same speed above and below the sample. Same speed is synonymous with the same heat transfer, since this is proportional to the speed. With the same Heat transfer goes hand in hand with the temperature distribution is improved to the same extent.
- For homogenizing the airflow becomes a system of corresponding shaped, structured perforated sheets used disassemble the incoming airflow and over the entire Distribute the duct cross-section evenly by the Large number of component streams aligned in an X-shape will.
- the single partial flow shows again laminar flow pattern, because of the exact quantity distribution over the flow cross section results however, a homogeneous temperature profile over the entire Sample area.
- the entire mixing system can act as an air rectifier be understood and each consists of several Mixing or homogenizing units. After every unit the main air direction is changed while doing so each individual partial stream is broken down again. After three Elements, the air flow is already homogenized that with the now existing overall speed profile Accuracies of +/- 2.5 K can be achieved which is sufficiently precise for the user.
- mixing performance is independent of the amount of air circulated, therefore with this furnace system it is possible to do any to simulate practical conditions.
- CC systems are running in practice today with throughput speeds that correspond to a drying time of approx. 30 s.
- the Homogenization of the air flow in terms of its speed is the main aspect of the invention.
- Figs. 1 and 2 is the basic structure of the Laboratory furnace 10 shown.
- the furnace 10 a heat insulated housing 12 on the front wall 14 a drawer 16 with a receiving device 18 for receiving a painted metal plate 20 (Sample) is arranged.
- the receiving device 18 is located when the drawer 16 is pushed in Air flow channel 22 and divides it into an upper one Section 24 and a lower section 26. Of the upper section 24 of the air flow channel 22 ends immediately above the metal plate 20 during the lower portion 26 of the air flow channel 22 immediately ends below the receiving device 18.
- Fresh air is supplied to the system via a fresh air supply 42 supplied with filter 44, while exhaust air via a Exhaust duct 46 arrives from the interior 28 of the furnace 10.
- a fresh air supply 42 supplied with filter 44
- exhaust air via a Exhaust duct 46 arrives from the interior 28 of the furnace 10.
- a fresh air supply 42 supplied with filter 44
- Exhaust duct 46 arrives from the interior 28 of the furnace 10.
- two circulating air flows over which the metal plate 20 from its top and hers Underside is supplied with warm air.
- the perforated plates 52 are corrugated in a zigzag shape and exhibit a variety of especially regular arranged holes 54 on.
- the perforated plates 52 each Perforated plate pack 50 lie close together. Because of the zigzag structure has each perforated plate 52 Variety of elevations 56 and depressions 58 on the per perforated plate 52 all run parallel to one another. The alignment of the elevations 56 and depressions 58 is angled to flow direction 60, and in particular at an angle of 45 °.
- the elevations 56 and depressions 58 run adjacent Perforated plates 52 cross each other.
- the order the perforated plates 52 is such that they are in Flow direction 60 parallel planes extend.
- the Perforated plates 52 upstream in the direction of flow 60 arranged unit 50 are also opposite by 90 ° the perforated plates 52 of the downstream unit 50 twisted arranged. All these characteristics of the perforated plates 52 and their relative arrangements are shown in FIGS. 4 to 7 reproduced in the drawing, the FIGS. 4 and 5 two adjacent perforated plates 52 arranged upstream Unit 50 and the FIGS. 6 and 7 two neighboring ones Perforated plates 52 of the downstream unit 50 of the Show airflow equalization device 48.
