Description

一种制氧机
技术领域
本发明涉及一种制氧机 。
背景技术
目前的制氧机一般包括两个分子筛筒、储氧筒和电磁阀，两个分子筛筒之间通过管道连通，储氧筒通过管道分别和两个分子筛筒连通，电磁阀设于两个分子筛筒的一端并通过管道分别和两个分子筛筒连通。其运行方式为：将外部供应的气体经过电磁阀的控制送入其中一个分子筛筒内，利用内部特殊的分子吸附氮气，剩余气体即高纯度的氧气经管道进入储氧筒内，而同时另外一个分子筛筒也经电磁阀控制将内部的氮气排出至外界。如此反复运作，即可持续输出高纯度的氧气，但此结构由于各构件之间通过相应的管道连接，在组装时须将管道依序连接至相对应的构件处，且组装后也须检测各管道是否有泄漏的情况，杂乱相错的管道分布，增加了日后维修保养的困难度，费时又麻烦；裸露的管道杂乱无章，导致制氧机外形极为难看；而且这种制氧机的构件数目众多，需较多的空间分别存储放置，通常需另外配合一个大型的箱体来存放整体构件，增加了生产成本。
发明内容
为解决上述问题，本发明提供一种使用和拆卸方便、制造成本低的制氧机。
本发明为解决其问题所采用的技术方案是：
一种制氧机，包括两个分子筛筒、一自动控制阀和一储氧单元，分子筛筒的一端与自动控制阀相连通，分子筛筒的另一端与储氧单元连通，所述分子筛筒的端部扣接有制氧系统上盖和 / 或制氧系统下盖，制氧系统上盖和 / 或制氧系统下盖内设置有能够连通制氧机上述各构件之间的气体流道。
作为上述方案的改进，制氧系统上盖的一侧与自动控制阀连通，另一侧与一排气单元相连通。
所述制氧系统上盖扣接于分子筛筒上端，制氧系统上盖的盖体内侧设置有排气流道、进气流道及供气流道，排气流道与所述的排气单元相连通，进气流道分别与对应位置的分子筛筒相连通，供气流道则与外部的供气设备相连通，所述的自动控制阀分别与制氧系统上盖内的排气流道、进气流道及供气流道相连通。
所述制氧系统下盖扣接于分子筛筒下端，制氧系统下盖的盖体内侧设置有储氧流道与通气流道，分子筛筒与储氧单元之间通过储氧流道相连通，分子筛筒之间通过通气流道连通。
本发明的有益效果是：本发明的制氧机将原本设置在分子筛筒两端杂乱分布的流体管道，整合为扣接于分子筛筒两端的制氧系统上盖和 / 或制氧系统下盖，并通过隐藏在各模组内部的各种气体流道取代其功能，让原先需连接多管道作业转变成将气体流道模块与分子筛筒组合固定即可完成，大幅减小了制氧机的构成零件数目，不但使得组装和拆卸、生产及检测维修更为容易，而且能够有效降低制造成本，将气体流道模块分为制氧系统上盖和 / 或制氧系统下盖，既可以两个部件一起使用，也可将单一部件个别取代旧用制氧机的部分构件，发挥适当的功效，使用范围较大，兼容性较强。

图 1 为本发明的结构示意图；
图 2 为为制氧系统上盖的结构示意图；
图 3 制氧系统上盖的剖视图；
图 4 为图 1 中的制氧系统上盖与自动控制阀从另一角度的分解图；
图 5 为制氧系统下盖的结构示意图；
图 6 为制氧系统下盖的剖视图。
具体实施方式
参照图 1 ，一种制氧机，包括两个分子筛筒 1 、 2 ，以及一个自动控制阀 3 和一个储氧单元 4 ，分子筛筒 1 、 2 的一端与自动控制阀 3 相连通，分子筛筒 1 、 2 的另一端与储氧单元 4 连通，所述分子筛筒 1 、 2 的上端扣接扣接有制氧系统上盖 5 ，分子筛筒 1 、 2 的下端扣接有制氧系统下盖 6 ，制氧系统上盖 5 和制氧系统下盖 6 内设置有能够连通制氧机上述各构件之间的气体流道。这种结构大幅减小了制氧机的构成零件数目，在保证能实现制氧机各构件之间有效连通的同时，不但使得组装和拆卸、生产及检测维修更为容易，而且能够降低制造成本。
进一步，制氧系统上盖 5 的一侧与自动控制阀 3 连通，另一侧与一排气单元 7 相连通。作为优选的方式，采用消音管作为排气单元 7 ，能够有效降低排出气体时产生的噪音。
参照图 2 至图 4 ，所述制氧系统上盖 5 的盖体内侧设置有排气流道 51 、进气流道 52 及供气流道 53 ，排气流道 51 与所述的排气单元 7 相连通，进气流道 52 分别与对应位置的分子筛筒 1 、 2 相连通，供气流道 53 则与外部的供气设备相连通，所述的自动控制阀 3 分别与制氧系统上盖 5 内的排气流道 51 、进气流道 52 及供气流道 53 相连通。相应地，制氧系统上盖 5 还设置有排气流道 51 的排气入口 511 和 512 、进气流道 52 的进气入口 521 和 522 、供气流道 53 的供气出口 531 。其中进气入口 521 、 522 以及供气出口 531 分别与自动控制阀 3 连通，进气流道 52 使外界气体能够进入分子筛筒 1 、 2 内，也可以使分子筛筒 1 、 2 内的氮气经此流至自动控制阀 3 排出。
自动控制阀 3 与制氧系统上盖 5 连接处设有嵌沟 30 ，嵌沟 30 内安装有相应形状的密封垫片 31 。自动控制阀 3 上设置有出入口 32 、 33 、 34 、 35 、 36 ，分别与排气流道 51 的排气入口 511 、进气流道 52 的进气入口 521 、供气流道 53 的供气出口 531 、供气流道 53 的供气出口 522 、排气流道 51 的排气入口 512 连通，嵌沟 30 设置于上述各出入口 32 、 33 、 34 、 35 、 36 的周围。
参照图 5 至图 6 ，所述制氧系统下盖 6 的盖体内侧设置有储氧流道 61 与通气流道 62 ，各分子筛筒 1 、 2 与储氧单元 4 之间通过储氧流道 61 相连通，各分子筛筒 1 、 2 之间通过通气流道 62 连通。
储氧流道 61 内设有使氧气仅能由分子筛筒 1 、 2 经储氧流道 61 进入储氧单元 4 内的单向阀 610 。
通气流道 62 内设有一控制分子筛筒 1 、 2 之间气体流量的节流阀 620 。
所述单向阀 610 为一覆盖于储氧流道 61 的入口处的、具有弹性的膜片。
制氧机整体的运作过程为：供气设备将外界气体经过供气流道 53 的供气出口 531 送至自动控制阀 3 处，首先将使进气流道 52 和供气流道 53 连通，自动控制阀 3 经内部切换使排气入口 511 关闭，气体通过进气入口 521 暂时送至分子筛筒 1 内，利用其内部特殊的分子将氮气吸附于筒内，剩余气体即为高纯度的氧气，再经由底部的制氧系统下盖 6 进入储氧单元 4 内，与此同时，另外一个分子筛筒 2 因自动控制阀 3 的控制，使得制氧系统上盖 5 在两个进气流道 52 之间连通，由于排气单元 7 与外界连通，使分子筛筒 2 内处于高压状态的氮气经前述流道自然向处于大气压力下的排气单元 7 方向排出，而在排氮过程中，制氧系统下盖 6 内的通气流道 62 因节流阀 620 的关系，也提供少量高压的氧气由分子筛筒 2 底部进入，加速内部氮气有效排出。当分子筛筒 1 吸附氮气达到饱和时，自动控制阀 3 再次切换回路，依前述相同的原理使分子筛筒 2 进行制氧的动作，而分子筛筒 1 进行排氮气的作业，如此反复不断运作，即可持续提供高纯度的氧气输出。
上述只是对本发明的优选实施例进行了图示和描述，但本发明的实施方式并不受上述实施例的限制，只要其以基本相同的手段达到本发明的技术效果，都应属于本发明的保护范围。
