Description

一种烘箱 技术领域
本发明涉及烘箱的技术领域，特别涉及一种烘箱。
背景技术
浸渍生产线已广泛应用于家具板、水泥模板、地板、防火板等生产中，原料普遍利用纸板，在生产线中，纸板通过浸渍之后，必须要通过烘干才能用于应用。现有技术中的烘箱，将烘干过程中产生的湿气通过湿气管道排出，湿气排出时，必将带走部分热量，影响烘箱的烘干效率。
发明内容
本发明的目的在于提供一种烘箱，解决上述现有技术问题中的一个或者多个。
本发明提供一种烘箱，包括烘箱本体、第一静压箱、第二静压箱和第三静压箱，烘箱本体顶部设有热风机，热风机上部设有吸风口，第一静压箱设于热风机的两侧，第一静压箱与第二静压箱连通，第一静压箱与第三静压箱连通，第二静压箱上设有多个第一喷嘴，第三静压箱上设有多个第二喷嘴，烘箱本体两侧设有出风口，出风口通过第一管路与热风机的吸风口连通，第一管路上依次设有风机、干燥装置和热交换器。
在一些实施方式中，第一喷嘴和第二喷嘴在同一平面上交叉排列，第一喷嘴和第二喷嘴中间留有一定空隙。
在一些实施方式中，干燥装置为可开启闭合的盒体，盒体设于第一管路内，盒体内填充有活性炭。
有益效果：本发明实施例的烘箱实现了热风的内部循环，将烘干过程中产生的水汽通过干燥装置吸收，大幅度减少了热量的损失，大大提高了热能的利用率。且该烘箱的喷嘴设计合理，不仅保证了热风的流速和风量，而且还能保证气流的方向，合理地分配了热气流的水平和垂直的分量，对纸进行合理而充分的烘干。
附图说明
图1为本发明一实施方式中一种烘箱的结构示意图。
具体实施方式
下面结合说明书附图，对本发明进行进一步详细的说明。
如图1所示，
一种烘箱，包括烘箱本体1、第一静压箱2、第二静压箱3和第三静压箱4，烘箱本体1顶部设有热风机7，热风机7上部设有吸风口8，第一静压箱2设于热风机7的两侧，第一静压箱2与第二静压箱3连通，第一静压箱2与第三静压箱4连通，第二静压箱3上设有多个第一喷嘴5，第三静压箱4上设有多个第二喷嘴6，烘箱本体1两侧设有出风口10，出风口10通过第一管路9与热风机7的吸风口8连通，第一管路9上依次设有风机11、干燥装置12和热交换器13。
热风通过第一静压箱2分别进入第二静压箱3和第三静压箱4，然后通过多个第一喷嘴5和多个第二喷嘴6对纸张进行烘干。而烘干过程中产生的水汽及风水通过第一管路9进行内部循环，干燥装置12吸附循环热风的水汽，热交换器13对循环的热风进行再次加热以达到干燥的需求，从而再次进入第一静压箱2。
进一步的，第一喷嘴5和第二喷嘴6在同一平面上交叉排列，第一喷嘴5和第二喷嘴6中间留有一定空隙。如此设计，保证了气流的方向，合理分配了热气流的水平和垂直的分量，低纸进行合理而充分的烘干。
进一步的，干燥装置12为可开启闭合的盒体，盒体设于第一管路9内，盒体内填充有活性炭。通过活性炭对烘干过程中的水汽进行吸附，当吸附饱和时，可通过简单更换盒体，来更换新鲜的活性炭吸附剂。
本发明提供的实施方案中的一种烘箱实现了热风的内部循环，将烘干过程中产生的水汽通过干燥装置吸收，大幅度减少了热量的损失，大大提高了热能的利用率。且该烘箱的喷嘴设计合理，不仅保证了热风的流速和风量，而且还能保证气流的方向，合理地分配了热气流的水平和垂直的分量，对纸进行合理而充分的烘干。
以上表述仅为本发明的优选方式，应当指出，对本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些也应视为本发明的保护范围之内。
