Far infrared drying equipment

Abstract

The invention discloses far infrared drying equipment and relates to the technical field of drying equipment. The far infrared drying equipment comprises a drying box body, wherein a drying chamber isarranged in the drying box body, a plurality of far infrared radiant panels are alternately arranged on two opposite inner side walls of the drying chamber in a staggered manner in a vertical direction. The free ends of the far infrared radiant panels incline downward. Each far infrared radiant panel successively comprises a supporting layer, a reflective layer, an infrared radiant layer and a wear-resistant layer from bottom to top. The far infrared radiant panel successively comprises the supporting layer, the reflective layer, the infrared radiant layer and the wear-resistant layer from bottom to top, wherein the supporting layer can support the dead weight of the far infrared radiant panel and the impact force of a material, and the reflective layer can reflect far infrared rays emitted by an infrared radiant layer to the upper surface of the far infrared radiant panel, so that the drying efficiency is improved. The wear-resistant layer can protect the infrared radiant layer, so that reduction of drying efficiency and material pollution due to wear of the infrared radiant layer after long-time use is avoided.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a far-infrared drying equipment. Background technique [0002] The wavelength of far-infrared rays is between 4 and 400 microns, which can be directly heated from the inside of the material, which is conducive to the rapid evaporation of internal moisture. Compared with traditional hot air drying, far-infrared drying does not need to directly heat the air around the material, and has the advantages of high efficiency and energy saving, so it has been widely used in many fields. At present, the far-infrared drying equipment used on a large scale is mainly silicon carbide infrared radiation electric heater, milky white quartz infrared radiation electric heater, ceramic infrared radiation electric heater, resistance band infrared radiation electric heater and coal and flue gas infrared radiation heating device etc. These traditional infrared radiation devices have the fol...

AI Technical Summary

Problems solved by technology

These traditional infrared radiation devices have the following disadvantages: first, the energy consumption is high, and far-infrared rays must be emitted at a certain high temperature; second, the energy utilization rate of the far-infrared radiation heater is heated by burning coal, oil and natural gas Low, and due to insufficient combustion of fuel, it will also cause certain pollution to the environment; third, the use of fuel-powered infrared radiation heaters, not only the temperature is difficult to control during the drying process, but also the use of open flames is easy to cause fires, so the safety is poor

However, since there is no protective layer on the outside of the infrared coating on the infrared radiation light wave plate, the infrared coating material will inevitably fall off during long-term use, resulting in reduced drying efficiency and material contamination

Moreover, this design increases the structural complexity and cost of the device, while reducing safety and increasing the failure rate of the device
