Description

一种远红外干燥设备 技术领域
本发明涉及干燥设备技术领域，特别是涉及一种远红外干燥设备。
背景技术
远红外线的波长在4～400微米，可以从物料的内部直接进行加热，有利于内部水分快速蒸发。相对于传统的热风干燥，远红外干燥无需对物料周围空气直接加热，具有高效节能的优势，因此在很多领域得到了广泛的应用。目前大规模使用的远红外线干燥设备主要是碳化硅红外辐射电加热器、乳白石英红外辐射电加热器、陶瓷红外辐射电加热器、电阻带式红外辐射电加热器和煤与烟气红外辐射加热器等。这些传统的红外辐射器件具有以下缺点：第一、能耗高，必须在一定的高温下才能发射远红外线；第二、通过燃烧煤、石油和天然气等来加热远红外辐射加热器的能量利用率低，而且由于燃料的燃烧不充分，还会对环境造成一定的污染；第三、使用燃料供能的红外辐射加热器，干燥过程中不但温度难以控制，而且使用明火容易引发火灾，所以安全性差。
近年来，人们发现碳材料通电后在较低的功率密度下可以发射远红外线，并且能量转换效率高达99％，是一种非常理想的红外发射材料。专利CN105135851A公开了一种带式红外辐射干燥系统及其安装和干燥方法，将碳材料制备的红外辐射光波板分别安置于传送带的上方和下方，物料在随传送带输送的过程中，位于传送带上方和下方的红外辐射光波板在通电的情况下辐射出红外光波，对物料进行干燥。但是，由于红外辐射光波板上的红外涂层外部没有保护层，红外涂层材料在长期使用过程中不可避免地会脱落，导致干燥效率 降低和物料污染。而且，此设计提高了设备的结构复杂性和成本，同时降低了安全性并增加了设备的故障率。

具体实施方式
为使本发明的内容更容易被清楚地理解，下面根据具体实施方式并结合附 图，对本发明作出进一步详细的说明。
本实施例提供了一种远红外干燥设备，包括干燥箱体1，该干燥箱体1内设置有用于对物料进行干燥的干燥室2。该干燥室2的上部开设有进口。在干燥室2内的左侧壁和右侧壁上由上向下依次交错设置有若干块远红外辐射板3，这些远红外辐射板3的自由端均向下倾斜，且每块远红外辐射板3的自由端均伸至位于其下方的远红外辐射板3的上方。待干燥的物料由沿远红外辐射板3滑动后自动掉落至下一块远红外辐射板3。
在干燥箱体1内还安装有螺旋进料器10，该螺旋进料器10的进料端位于干燥箱体1的底部，且与干燥箱体1的进料口11连通，螺旋进料器10的出料端位于干燥箱体1的顶部，且与干燥室2的进口连通，干燥室2的底部设置有出料管12，出料管12与螺旋进料器10的进料端连通，出料管12上设置有阀门13，出料管12上位于所述阀门13与干燥室2之间开设有出料口14。
螺旋进料器10可将待干燥的物料输送至干燥箱体1的顶部，随后进入干燥室2内，在各远红外敷设板之间一次靠重力滑动下落，实现对物料的干燥，另外，在待干燥的物料没有达到干燥要求之前，可将出料管12上的出料口14关闭，并打开阀门13，物料受重力作用达到螺旋进料器10的底部后，再经过螺旋进料器10的传输达到干燥箱体1的顶部，随后再次进入干燥室2内，实现多次干燥，在物料达到干燥要求后，关闭阀门13，打开出料口14，物料便可从出料口14离开干燥箱体1，完成干燥。
较佳的，每块远红外辐射板3均通过铰链铰接在干燥室2的内侧壁上，使远红外辐射板3与干燥室2内侧壁之间的夹角可调。在远红外辐射板3的下表面 焊接有支撑件9，该支撑件9的一端可固定连接在干燥室2的内侧壁上，使支撑件9可对远红外辐射板3进行支撑。需要说明的是，支撑件9可固定连接在干燥室2内侧壁的不同高度，从而对远红外辐射板3与水平方向的夹角进行调节，进而使远红外干燥设备可适应于不同堆积角度的物料。支撑件9与干燥室2内侧壁之间的连接方式并不固定，只需可实现支撑件9与干燥室2内侧壁之间的可拆卸连接即可。如干燥室2内侧壁上可沿竖直方向开设多个安装孔，通过调节支撑件9安装的安装孔的高度即可调节远红外辐射板3与水平方向的夹角。
其中，每块远红外辐射板3由下往上均依次包括支撑层4、反射层5、红外辐射层6以及耐磨层7。支撑层4为不锈钢钢板，可支撑远红外辐射板3的自重以及物料的冲击力。反射层5为涂覆在支撑层4上表面的金属盐或陶瓷，用来反射远红外线，使远红外线都向远红外辐射板3的上表面发射，提高干燥效率。红外辐射层6由石墨、膨胀石墨、活性炭、碳纳米管、石墨烯或碳纤维中的一种或多种碳材料混合制成，红外辐射层6可将电能转化成远红外线，在较的低功率密度下就可以辐射出干燥物料所需要的远红外线。耐磨层7由聚乙烯、高密度聚乙烯、聚四氟乙烯、甲基丙烯酸甲酯、聚异戊二烯塑料或钢化玻璃制成，抗磨损且不吸收或反射远红线，在保证远红外辐射板3正常使用的前提下对红外辐射层6进行有效保护，避免长时间使用后红外辐射层6被磨损而导致干燥效率降低和物料污染。
较佳的，在耐磨层7的上表面均匀开设有若干条导流槽8，这些导流槽8均沿远红外辐射板3的对角线方向设置，且任意相邻的两块远红外辐射板3上的导流槽8相交。可延长物料在远红外辐射板3上的移动距离，从而提高对物料的干燥效率。
另外，在干燥室2内的前侧壁和后侧壁上分别开设有进风口15和出风口16，进风口15通过安装在干燥箱体1外前侧壁上的干空气风道17与送风机19连通，送风机19可将干燥箱体1外的干空气输送至干空气风道17内，并通过进风口15送入干燥室2内。出风口16通过安装在干燥箱体1外后侧壁上的湿空气风道18与引风机20连通，干燥室2内的湿空气在引风机20的牵引下由出风口16和湿空气风道18排出至干燥箱体1外，从而将物料蒸发出的水分排出干燥箱体1。
在干燥室2内还安装有温/湿度检测器21，该温/湿度检测器21、送风机19和引风机20均与干燥箱体1外的控制器电连接，在物料干燥的过程中，温/湿度检测器21实时监测干燥箱体1内的温度、湿度并反馈给控制器，中央控制器根据温/湿度检测器21反馈的数据实时调整远红外辐射板3和送风机19、引风机20的运行，以避免物料受损。
除上述实施例外，本发明还可以有其他实施方式；凡采用等同替换或等效变换形成的技术方案，均落在本发明要求的保护范围。
