Description

一种热风循环烘箱 技术领域
本发明涉及一种烘箱，更具体的涉及一种热风循环烘箱，属于制药设备技术领域。
背景技术
在药品生产过程中，通常要对药品中某些原料进行干燥处理，目前经常使用的是热风循环风箱，风源由循环送风电机带动风轮经由加热器，而将热风送出，再经由风道至烘箱内室，再将使用后的空气吸入风道成为风源再度循环，加热使用。常用的热风循环烘箱风机在箱体两侧，对内室的加热很不均匀，同时由于两侧布置有加热管，所以遇到高温烘箱的情况下，就要另外接水管对电机进行冷却，很不方便有浪费能源。
发明内容
发明目的：本发明目的在于针对现有技术的不足，提供一种加热均匀、节约能源、使用方便的热风循环烘箱。
技术方案：本发明所述一种热风循环烘箱，包括箱体、设置于箱体两侧的出风风道和设置于所述箱体内部的层级烘架，箱体的顶部设置风机，所述风机的风道呈R型设计，所述R型风道的尾部与所述箱体的侧壁的出风风道连通，所述R型风道的头部设置于所述箱体顶部的中心位置，所述风机设置于所述R型风道的头部，并与所述箱体的内部连通。
本申请技术方案的进一步限定为，所述风机为长轴式轴流风机。
进一步地，所述R型风道与所述箱体的顶部之间设置隔热层。
进一步地，所述R型风道的尾部进风口还连接有补风通道。
进一步地，所述箱体两侧的出风风道里设置加热管。
进一步地，所述箱体的顶端还设置排湿风机，所述排湿风机的进风口与所述箱体的内腔连通。
有益效果：本发明提供一种热风循环烘箱，把风机放在顶部，并采用长轴式轴流风机，中间有隔热层，避免高温影响电机工作，也不需要水冷却，方便又节能；风机的风 道采用R型，加大了进风的风量，保证了进风的均匀性，同时，进风通道明显大于出风通道，加大了风压，使出风速度更快，气流进入箱体时从上而下的冲力大，使干燥更均匀。
附图说明
图1为本发明提供的热风循环烘箱的整体结构图；
图2为本发明提供的热风循环烘箱的结构透视图；
图3为本发明提供的R型风道的结构示意图。
具体实施方式
下面通过附图对本发明技术方案进行详细说明，但是本发明的保护范围不局限于所述实施例。
实施例1：一种热风循环烘箱，如图1、2所示，包括箱体1、设置于箱体1两侧的出风风道和设置于所述箱体1内部的层级烘架，所述箱体1两侧的出风风道里设置加热管。
本实施例中，箱体1的顶部设置风机2，所述风机2为长轴式轴流风机，轴流式风机通常应用在通风换气的场所，而本实施例中采用长轴式轴流风机，通过对风机旋转轴的加长设计，增大了风机与加热管之间的距离，避免了温度过高影响风机的工作。
所述风机2的风道呈R型设计，所述R型风道3的尾部与所述箱体1的侧壁的出风风道4连通，所述R型风道的头部设置于所述箱体1顶部的中心位置，所述风机2设置于所述R型风道3的头部，并与所述箱体1的内部连通。R型风道的设计，加大了进风量，保证了进风的均匀性，同时进风通道明显大于出风通道，加大了风压，使出风速度更快，气流进入箱体时从上而下的冲力大，使干燥更均匀。
另外，在风机2的循环过程中，会有空气损失，为了保证热风的充足性，本申请的R型风道3的尾部进风口还连接有补风通道6，在必要的时候开启补风。
所述R型风道3与所述箱体1的顶部之间设置隔热层，更进一步的降低了高温对电机的影响，在高温的环境下，也不需要进一步的水冷，方便又节能。
所述箱体1的顶端还设置排湿风机7，所述排湿风机7的进风口与所述箱体1的内 腔连通，在循环烘箱运行一段时间后，箱体内湿度较大时，启动排湿风机7，将湿度大的空气排出。
如上所述，尽管参照特定的优选实施例已经表示和表述了本发明，但其不得解释为对本发明自身的限制。在不脱离所附权利要求定义的本发明的精神和范围前提下，可对其在形式上和细节上作出各种变化。
