Description

[根据细则37.2由ISA制定的发明名称]　一种可调节栅板式远红外干燥装置[Title of invention formulated by ISA pursuant to Rule 37.2] An adjustable grid-type far-infrared drying device 技术领域technical field
本发明涉及干燥设备技术领域，尤其涉及一种高效率可调节栅板式远红外干燥装置。The invention relates to the technical field of drying equipment, in particular to a high-efficiency adjustable grid plate type far-infrared drying device.
背景技术Background technique
由于远红外辐射具有加热快速高效，无需介质参与的特点，因此已被广泛应用于加热领域，在粮食干燥机械中，日本金子农机公司和台湾三玖农机公司也引入了远红外加热干燥技术，具体原理是利用远红外线能在稻谷、小麦和玉米表面形成一定的穿透深度，从物料内部和外部同时进行加热，使物料内部的水分能快速扩散至表层。这一技术大大加快了物料的干燥速率，提高了能源利用率。但是，目前市场上的远红外干燥机械全部采用柴油燃烧作为热源，将远红外线发射涂层的温度升高而产生辐射，因此仍旧存在远红外发射涂层老化脱落、燃烧能量多次转化效率降低，以及容易引发火灾等安全隐患。Because far-infrared radiation has the characteristics of fast and efficient heating without media participation, it has been widely used in the field of heating. In grain drying machinery, Japan's Kaneko Agricultural Machinery Company and Taiwan Sanjiu Agricultural Machinery Company also introduced far-infrared heating and drying technology. The principle is to use far infrared rays to form a certain penetration depth on the surface of rice, wheat and corn, and to heat from the inside and outside of the material at the same time, so that the moisture inside the material can quickly diffuse to the surface layer. This technology greatly speeds up the drying rate of materials and improves energy utilization. However, all the far-infrared drying machines on the market currently use diesel combustion as a heat source, and the temperature of the far-infrared emitting coating is raised to generate radiation. Therefore, there are still aging and falling off of the far-infrared emitting coating, and the efficiency of multiple conversion of combustion energy is reduced. And it is easy to cause fire and other safety hazards.
近年来，人们发现石墨化的碳材料具有在低功率密度的电能驱动下高效发射远红外线的特性，因此将其应用于物料干燥领域；现有的碳材料制备的辐射远红外线的干燥设备，其主要工作原理为将物料输送到烘干机内的最高位置，然后让物料沿着烘干机内部的远红外辐射板的导流槽自然下滑，在物料下滑的同时，用远红外辐射板发出的远红外线对物料进行加热干燥。虽然用碳材料制作的远红外辐射板的电热辐射转化高，但由于物料在远红外辐射板上的停留时间太短，且很难准确控制，干燥效率仍有很大提升空间，因此，本专利提出了一种安全、节能和高效可控的碳材料栅板式远红外干燥设备。In recent years, it has been found that graphitized carbon materials have the characteristics of emitting far-infrared rays efficiently under the drive of electric energy with low power density, so they are used in the field of material drying; the existing drying equipment for radiating far-infrared rays prepared by carbon materials has The main working principle is to transport the material to the highest position in the dryer, and then let the material slide down naturally along the diversion groove of the far-infrared radiation plate inside the dryer. Far infrared heats and dries the material. Although the far-infrared radiation plate made of carbon material has high electrothermal radiation conversion, because the residence time of the material on the far-infrared radiation plate is too short and it is difficult to accurately control, there is still a lot of room for improvement in drying efficiency. Therefore, this patent A safe, energy-saving and high-efficiency controllable carbon material grid plate type far-infrared drying equipment is proposed.
