Description

隧道式灭菌干燥机的烘烤箱体 技术领域
本实用新型主要涉及到食品、 制药等包装机械行业领域, 特指一种用于食品、 制药 等领域的灭菌干燥机。 在食品、 制药等包装机械行业中, 热风均匀性是热风循环式灭菌干燥机考证的重要 指标, 加热原理是通过加热器与循环风进行热交换, 把循环风加热通过热风机吹向风罩 内, 进高温高效过滤器后, 再与药瓶或食品进行热交换。 在通用的控制方式中一般采用 高温箱体中间一个温度探头作为控制点, 采集高温高效下部层流风的温度, 反馈给控制 器, 控制器再通过调节加热器的发热量, 来控制循环风的温度。但是, 随着产能的扩大, 隧道烘箱的长度不断加长, 仅采用中间一个点, 已不能控制整个面的温度, 经常出现前 后温度超高问题, 前后温度偏差不仅温度不均匀, 还将直接影响到机器性能, 温度过高 时将会损坏箱体内部零部件 (比如高温高效过滤器有最高温度限制) 。
实用新型内容
本实用新型要解决的技术问题就在于: 针对现有技术存在的技术问题, 本实用新型 提供一种结构简单紧凑、 成本低廉、 适用范围广、 热风均匀性好的隧道式灭菌干燥机的 烘烤箱体。
为解决上述技术问题, 本实用新型采用以下技术方案。
一种隧道式灭菌干燥机的烘烤箱体, 包括箱体以及装设于箱体内的进风腔、 传送网 带和回风通道,所述传送网带位于回风通道和进风腔之间,其特征在于:所述进风腔通过 一块以上的进风隔板将其分隔成两个以上独立的进风腔室,所述每个进风腔室内均设有 加热器以及由上至下依次布置的热风机、 散流风罩、 高温高效过滤器和温度探头, 所述 回风通道内与进风隔板对应的位置处设有回风隔板,所述回风通道通过回风隔板分隔成 两个以上的回风腔, 所述回风腔的出口端位于加热器的底部。
作为本实用新型的进一步改进:
所述回风腔内设有一个以上回流板,所述回流板通过将回风腔分隔成一个以上的回 风通道, 所述回风通道的出口端位于加热器的底部。
所述箱体的外表面设有保温层, 所述保温层上开设有补风口。 与现有技术相比, 本实用新型的优点就在于:
本实用新型隧道式灭菌干燥机的烘烤箱体,通过进风隔板将箱体内进风腔依次分隔 成各自独立的进风腔室, 每个进风腔室内均设有独立的热风机、 加热器、 风罩、 高温高 效过滤器、 补风口以及温度探头, 这样就将长的腔室分隔为小腔室, 由小腔室内的温度 探头、 加热器和风机控制该腔室内层流风的温度, 使腔室内的纵截面的温度更加均匀, 从而提高整机的热风均匀性, 且可适用于各种产能的生产线。
附图说明
图 1是本实用新型横截面的结构示意图;
图 2是本实用新型纵截面的结构示意图;
图 3是本实用新型的俯视结构示意图。
图例说明:
1、 箱体; 2、 热风机; 3、 散流风罩; 4、 高温高效过滤器; 5、 温度探头; 6、 药 瓶; 7、 传送网带; 8、 回流板; 9、 加热器; 11、 进风隔板; 15、 回风隔板; 21、 进风 腔室; 22、 回风通道; 23、 回风腔; 24、 进风腔; 25、 补风口; 26、 保温层。
具体实施方式
以下将结合具体实施例和说明书附图对本实用新型做进一步详细说明。
如图 1、 图 2和图 3所示, 本实用新型的隧道式灭菌干燥机的烘烤箱体, 包括箱体 1以 及装设于箱体 1内的进风腔 24、 传送网带 7和回风通道 22, 传送网带 7位于回风通道 22和 进风腔 24之间,进风腔 24通过一块以上的进风隔板 11将其分隔成两个以上独立的进风腔 室 21, 每个进风腔室 21内均设有加热器 9以及由上至下依次布置的热风机 2、 散流风罩 3、 高温高效过滤器 4和温度探头 5, 回风通道 22内与进风隔板 11对应的位置处设有回风隔板 15, 回风通道 22通过回风隔板 15分隔成两个以上的回风腔 23, 回风腔 23的出口端位于加 热器 9的底部。 回风腔 23内设有一个以上回流板 8, 回流板 8通过将回风腔 23分隔成一个 以上的回风通道,回风通道的出口端位于加热器 9的底部。箱体 1的外表面设有保温层 26, 保温层 26上开设有补风口 25。 参见图 2, 本实施例中是采用进风隔板 11将进风腔 24分割 为三段, 同时用回风隔板 15将回风通道 22分隔成两个以上的回风腔 23。 在工作区域为相 通的,只要保证各段风向为向下的层流,通过每段相对较小的腔室内控制层流风的温度, 多段合起来即可控制整个烘箱的内腔室的热风温度, 使纵截面上的温度更加均匀。
每个进风腔室 21内的热风循环的动力来自于热风机 2, 热风机 2吸入由加热器 9加热 的热风, 吹入到散流风罩 3内 (图中箭头方向即为热风的流向) , 散流风罩 3将热风机 2 出来的风分散, 让热风在散流风罩 3内的风压比较均匀, 热风经高温高效过滤器 4过滤后 流出。 热风经过温度探头 5, 再到达传送网带 7上的药瓶 6后, 与药瓶 6进行冷热交换。 随 着热风的温度下降, 药瓶 6的温度上升, 药瓶 6是由传送网带 7输送到箱体 1内的。 热风再 经过回风通道 22后经回流板 8重新到达加热器 9, 如此循环。 由于箱体 1两端开口, 高温 的热风会向外流出一部分, 所以在每个独立的腔室内的回风通道上设置补风口 25, 控制 方式就是通过温度探头 5检测各个进风腔室 21内的热风温度反馈给控制机构, 再由控制 机构控制每个加热器 9的发热量, 最终来控制经过每个加热器 9的热风温度。 如果温度探 头 5的检测温度低于设定值, 控制机构将提高加热器 9的发热量, 使经过加热器 9的热风 温度上升, 从而提高进入进风腔 24内的热风温度。 反之降低加热器 9的发热量, 降低进 风腔 24内的热风温度。
以上所述仅是本实用新型的优选实施方式,本实用新型的保护范围并不仅局限于上 述实施例, 凡属于本实用新型思路下的技术方案均属于本实用新型的保护范围。 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原理前提下的若干改进 和润饰, 这些改进和润饰也应视为本实用新型的保护范围。
