Abstract

[Problem] To provide a far-infrared drying device that allows for adjustment of the distance between the device and the object to be dried. [Solution] The present invention provides a far-infrared drying device that allows for adjustment of the distance to the object being dried by moving a movable frame vertically or horizontally, taking into account the size of the object being dried. This prevents the problem of reduced energy efficiency during the drying process due to the use of excessive power relative to the size of the object being dried, which occurs when the distance between the far-infrared generator and the object being dried cannot be adjusted according to the size of the object being dried.

Description

This invention relates to a far-infrared drying apparatus that allows for adjustment of the distance between the device and the object to be dried. Organic compounds, such as paints, have the property of drying by partially absorbing far-infrared radiation. In particular, organic compounds primarily absorb far-infrared radiation with wavelengths between 4 μm and 1000 μm within the far-infrared wavelength range. Far-infrared rays absorbed by organic compound molecules resonate, causing molecular motion. This increased kinetic energy is converted into thermal energy, raising the temperature of the paint itself and accelerating drying. Figure 1 is a schematic diagram showing a conventional large-scale, space-based paint drying system 1 that uses far-infrared radiation. Referring to Figure 1, the structure of a conventional large-scale, stationary paint drying facility 1 using far-infrared radiation consists of a far-infrared radiation generator 2 that emits far-infrared radiation, an object to be dried 3, paint 4 that constitutes the coating, and a reflector 5. The far-infrared generator 2 is fixedly installed on the top and sides of the paint drying equipment 1. The far-infrared rays emitted from the far-infrared generator 2 pass through the indoor air within the paint drying equipment 1 and are absorbed by the paint 4 on the object to be dried 3. This increases the surface temperature of the object to be dried 3, accelerating drying. Of the far-infrared rays emitted towards the object to be dried 3, those not absorbed by the paint 4 are reflected by the reflector 5, return towards the object to be dried 3, and are absorbed by the paint 4 on its surface. However, the far-infrared energy emitted from the far-infrared generator 2 weakens in intensity as the distance from the object to be dried 3 increases, based on the inverse square root law. Specifically, if the object to be dried 3 is large enough to receive far-infrared rays and is close to the far-infrared generator 2, the energy intensity does not decrease significantly, and the surface temperature of the object to be dried 3 can be easily raised. However, if the object to be dried 3 is small, the energy intensity weakens as the distance to the far-infrared generator 2 increases. This leads to the problem of using excessive power that is unnecessary for the size of the object to be dried 3. Thus, conventional fixed-type far-infrared generators 2 cannot adjust the radiation distance of far-infrared rays according to the size of the object to be dried 3, potentially leading to the problem of unnecessarily using excessive power and reducing the energy efficiency of the drying process.
