Description
Technical Field
The utility model belongs to the technical field of infrared heating, and particularly relates to a full infrared spectrum heater and a drying device.
Background
The infrared heating has the characteristics of high heating speed, good directionality and excellent energy-saving effect, and becomes an important heating mode. The existing infrared heating mainly provides infrared sources through an infrared electric heating element, namely after the resistive electric heating element is electrified and heated to a certain temperature, the electric heating element excites infrared rays with corresponding wavelengths. The excited infrared wavelength is directly related to the temperature of the electric heating element, such as 2600 ℃ for mainly exciting short wave infrared, 2000-1000 ℃ for mainly exciting short medium wave infrared, and <1000 ℃ for mainly exciting medium and long wave infrared.
The materials and functions of different infrared matching are different, so that the infrared matching is often carefully selected in practical application, which brings a lot of difficulties to practical application and makes the drying and heating processes difficult to control. For example, short wave infrared has better penetrability to some solid materials, internal heating can be realized, but the absorption effect is relatively poor; the medium wave infrared can be effectively absorbed by the material surface (such as organic polymer, water, solvent, ceramic, etc.) and rapidly converted into heat; the long-wave infrared has better heating effect on most organic materials and aqueous solvent-containing slurry, and the heating process is milder and controllable.
In the actual heating or drying process, a relatively complex process is often accompanied, and it is difficult for a single infrared wavelength to meet the overall requirements. Taking a lithium battery pole piece coating process as an example: the initial section is a heating section, the infrared thermal effect is more important, and the solvent content in the pole piece is highest; the middle section is an evaporation section, infrared rays need to ensure certain penetrability to realize uniform heated drying of the pole piece, and the solvent content in the pole piece is changed from high to low; the rear section is a deep evaporation section, and the solvent in the pole piece gradually falls off until the slurry is completely changed into solid. The material ratio is continuously changed in the whole drying process. The use of a single wavelength infrared source does not meet practical needs; in addition, the existing infrared source mainly takes a lamp tube form, the infrared field is uneven, and a space to be optimized is reserved.
