Description

一种高效率的干燥机 技术领域
本实用新型涉及干燥设备技术领域，尤其涉及了一种高效率的干燥机。
背景技术
干燥机通常是将空气加热后形成热风对湿物料进行干燥的设备，例如沸腾干燥机等，具有干燥速度快，温度匀称，操作简便，清洗方便等优点。但是现有的干燥机存在如下缺陷：(1)待干燥物容易卡在流化床的某处，尤其是侧壁及角落，被卡住的物品干燥速度就较慢，造成这一现象的主要原因就是气流不均匀(通常是因为风道形状突变引起)，或者仅仅能够提供向上的吹力；(2)除湿效果有待提升，当热气流内的湿度较大时，即使气流速度与温度均较高，也会影响物品的干燥速度。
发明内容
针对现有技术存在的不足，本实用新型的目的就在于提供了一种高效率的干燥机，具有更佳均匀的气流，除湿性能更好，干燥速度快，提高了干燥效率。
为了实现上述目的，本实用新型采用的技术方案是这样的：一种高效率的干燥机，包括风管以及通过风管依次连接的热风机、流化室、除湿室，所述流化室的下部设置有第一进风格栅、顶部设置有第一出风格栅、侧壁设置有第二进风格栅；所述流化室的第一进风格栅与进气口之间设置有若干个匀流板，若干个匀流板呈喇叭状并开口向上；所述风管靠近进气口的周部开设有辅助风管，该辅助风管与第二进风格栅相连通；所述除湿室包括两个平行设置的第一金属管，两个第一金属管之间设置有若干个平行设置的第二金属管；所述第二金属管设有若干层平行设置的金属板，第一金属管连接有水冷装置；所述金属板的下方设置有集水盘，该集水盘连接有排水装置。
作为一种优选方案，所述第一进风格栅包括格栅框体、格栅本体，所述格栅本体通过固定轴件与格栅框体铰接，所述固定轴件位于格栅框体的一侧；所述格栅本体上均匀分布有通气孔，且格栅本体的一侧设置有倾斜的导流槽。
作为一种优选方案，所述第一出风格栅的结构与第一进风格栅的结构相同。
作为一种优选方案，所述第二进风格栅的结构与第一进风格栅的结构相同。
作为一种优选方案，所述除湿室与风管的进风口处通过分流锥支架设置有分流锥。
与现有技术相比，本实用新型的有益效果：本实用新型具有更佳均匀的气流，除湿性能 更好，干燥速度快，提高了干燥效率。
附图说明
图1是本实用新型的结构示意图；
图2是本实用新型中第一进风格栅的结构示意图。
具体实施方式
下面结合具体实施例对本实用新型作进一步描述。以下实施例仅用于更加清楚地说明本实用新型的技术方案，而不能以此来限制本实用新型的保护范围。
实施例：
如图1～2所示，一种高效率的干燥机，包括风管1以及通过风管1依次连接的热风机2、流化室3、除湿室4，所述流化室3的下部设置有第一进风格栅5、顶部设置有第一出风格栅6、侧壁设置有第二进风格栅7；所述流化室3的第一进风格栅5与进气口之间设置有若干个匀流板8，若干个匀流板8呈喇叭状并开口向上；所述风管1靠近进气口的周部开设有辅助风管9，该辅助风管9与第二进风格栅7相连通；所述除湿室4包括两个平行设置的第一金属管10，两个第一金属管10之间设置有若干个平行设置的第二金属管11；所述第二金属管11设有若干层平行设置的金属板12，第一金属管10连接有水冷装置13；所述金属板12的下方设置有集水盘14，该集水盘14连接有排水装置15。
具体的，所述第一进风格栅5包括格栅框体51、格栅本体52，所述格栅本体52通过固定轴件53与格栅框体51铰接，所述固定轴件53位于格栅框体51的一侧；所述格栅本体52上均匀分布有通气孔54，且格栅本体52的一侧设置有倾斜的导流槽55。
其中，格栅本体52一端可绕固定轴件53相对于格栅框体51旋转，通过在格栅本体52的两侧中部安装有把手56，方便清洗。进一步的，所述通气孔54位于格栅本体52外侧的角度要低于内侧。
具体的，所述第一出风格栅6的结构与第一进风格栅5的结构相同。
更为具体的，所述第二进风格栅7的结构与第一进风格栅5的结构相同。
进一步的，采用这种结构的第一进风格栅5、第一出风格栅6、第二进风格栅7，可以阻拦杂质，方便清洗。
具体的，所述除湿室4与风管1的进风口处通过分流锥支架16设置有分流锥17。
进一步的，分流锥支架16采用一个中间镂空型的支架，不影响气流的通过，分流锥17的直径较大端朝向金属板12，直径较小端连接分流锥支架16。
具体实施时，打开第一出风格栅6处的风管1及第一出风格栅6，将待干燥物放入流化室3内，打开热风机2产生热气流，在流化室3内放入带干燥的药品，当热气流经过匀流板8时，能够在匀流板8的作用下更加均匀，能够避免气流通道截面积的突变带来的气流不均匀的现象。在实际使用中，干燥机经常会出现待干燥物贴在侧壁上的情形，发生与热气流无法充分接触的现象，本实施例还设有流化室3的侧部还设有第二进风格栅7，第二进风格栅7通过辅助风管9连接进气口，第二进风格栅7通过辅助风管9用于向待干燥物提供横向的吹力，避免待干燥物贴在侧壁上；热气流流过待干燥物之后，经过除湿室4再次进入至热风机2，实现对热量的回收；热气流进入至除湿室4后，内部的水蒸气能够与温度较低的第二金属管11、金属板12充分接触，发生液化(气态水分变成液态)，液化之后的冷凝水进入至集水盘14，进而排出至排水装置15中，实现对热气流的除湿、干燥，提升药品的干燥效率。
以上所述仅是本实用新型的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型技术原理的前提下，还可以做出若干改进和变形，这些改进和变形也应视为本实用新型的保护范围。
