具体实施方式
下面针对附图对本发明的实施例作进一步说明：
由图所示，该小型硬性角膜接触镜抛光液自动清洗装置，包括容器1，所述容器1内部设有容腔，所述容器1上设有与容腔相通的排气管2和吸液管3，所述排气管2和吸液管3均为皮管，所述排气管2的出口端通过连接头4与真空发生器5的真空口相通，所述排气管2的进口端与容器通过连接件19相连接，所述吸液管3的进液口也通过连接件19与容器相连接，所述真空发生器5进气口与压缩气体的管道相通，所述吸液管3的进液口置于硬性角膜接触镜抛光的废液槽底部。利用正压气源产生负压，通过真空发生器5的喷管喷射压缩空气，在喷管出口形成射流，产生卷吸流动，在卷吸作用下，使得与排气管2相连接的容器1内的气体不断地被抽吸走，使容器1内的压力降至大气压以下，形成一定真空度，从而使得抛光废液从废液槽内被自动抽入容器之中。根据上述方案，由于采用一种完全新型的废液处理装置，通过该装置的吸液管3放置于抛光机上的废液槽内，能及时、快速的对废液槽内的废液进行吸收处理，有效的防止废液沉积在废液槽内溢出对环境带来不利影响，该装置具有使用方便，容易控制，安全性好的优点，通过抛光液的自动清洗提高硬性角膜接触镜的生产效率。
由图所示，所述真空发生器5的进气口通过气流控制开关6与压
缩气体的通道相通。在压缩气体的进口处设置一个气流控制开关6并通过皮管、连接头与压缩气体的管道相连接，通过气流控制开关6控制来达到所需气流量。
由图所示，所述真空发生器5的进气口通过减压阀7与压缩气体的管道相通，所述减压阀7上设有与内部通道相通的压力表8以及压力调节旋钮9。在压缩气体的进口处设置一个减压阀7，减压阀一端通过皮管、连接件与压缩气体的管道相连接，另一端通过连接件19、皮管18以及连接头与真空发生器5的进气口相连接，在减压阀7上还设置一个显示压强的压力表8以及根据需要可调节压力的压力调节旋钮9。
由图所示，所述真空发生器5的进气口与压缩气体的管道之间设有减压阀7、气流控制开关6，所述减压阀7一端通过连接件19、皮管18以及连接头4与真空发生器5的进气口相连接，另一端与气流控制开关6通过连接件19、皮管18相连接，所述气流控制开关6与压缩气体的管道相通，所述减压阀7上设有与内部通道相通的压力表7以及压力调节旋钮9。通过气流控制开关6控制来达到所需气流量，并通过显示压强的压力表8上的数值对减压阀7上的压力调节旋钮9进行调节。采用气流控制开关6和减压阀7的同时作用，能准确的根据需要对压缩气体进行调整以达到要求。
由图所示，所述吸液管3的进液口和出液口之间通过分接头10相连接，所述分接头10上设有至少2个接口11。在吸液管上设置一个分接口11，接口11可以为多个，当硬性角膜接触镜抛光机为多台时，可以根据需要来设置不同的接口11以便对多台抛光机进行同时清洗，从而有效的提高成本以及实现合理利用资源。
由图所示，所述容器1底部设有底座12，所述的底座12的侧部设有支架13，所述支架13上固定有撑板14，所述的减压阀7通过所述撑板14设于所述支架13上。设置的底座12和支架13均为硬质塑料，支架13通过螺栓20固定在底座12的侧面，撑板14通过螺栓20固定在支架13上，减压阀7固定在撑板14上。
