Description

一种射流真空泵
技术领域
本发明涉及一种吸负压设备，属于通过利用被泵送流体的惯性泵送流体的喷射泵技术领域。
背景技术
射流真空泵是利用机械、物理、化学或物化的方法，在封闭空间中产生、改善和维持真空的装置。一般由潜水泵、射流真空泵、泵箱三部分组成，被广泛用于石油、化工、食品、制药、轻工、环保等行业的减压蒸发、结晶、蒸馏、干燥、脱色、脱臭、真空输送等工艺之中。
现有射流真空泵中的喷嘴，如果喷嘴发生堵塞，要用软毛刷或牙签来清洁它并且清洁过程要十分的小心，可能扭曲孔口，另外，现有喷嘴承载压力低，效率低下，同时，喷口不可调节。
发明内容
本发明要解决的技术问题是，针对现有技术不足，提出一种承载压力高且清洁性能好的射流真空泵的工作方法。
本发明为解决上述技术问题提出的技术方案是：一种射流真空泵，包括潜水泵、射流器和真空罐，所述射流器包括设有出口的射流盒，所述射流盒内设有相对的左、右夹板，所述左、右夹板之间形成射流喷嘴，所述左、右夹板的间距为8-20mm，所述射流喷嘴出口端与射流盒出口相对设置，所述左夹板中心处设有与左夹板垂直的射流液体进口管，所述射流液体进口管一端连通潜水泵出口，所述射流液体进口管另一端延伸到射流喷嘴处，所述右夹板边沿处设有与射流喷嘴连通的进气管，所述进气管连通真空罐出口。该射流真空泵的工作方法，包括：使用时，通过潜水泵将射流液体从射流液体进口管输入，通过射流喷嘴将射流液体加速，从而通过进气管将进气管连通的真空罐进行抽真空。
本发明采用上述技术方案的有益效果是：1）通过射流盒内设有相对的左、右夹板，左、右夹板之间形成射流喷嘴，左、右夹板的间距为8-20mm，创造性的将传统的喷嘴通过两个平板进行体现，简化了结构，提高了喷嘴的承载压力，喷嘴清洁性能好；2）通过左夹板中心处设有与左夹板垂直的射流液体进口管，右夹板边沿处设有与射流喷嘴连通的进气管，可以充分的利用左、右夹板之间形成的射流喷嘴内的高流速和低压力，对进气管内气体进行更高效率的抽吸。
上述技术方案的改进是：所述左、右夹板之间穿设有螺栓，所述螺栓的两端分别与左、右夹板螺接且分别悬伸出左、右夹板。
本发明采用上述技术方案的有益效果是：通过左、右夹板之间穿设有螺栓，螺栓的两端分别与左、右夹板螺接且分别悬伸出左、右夹板，可以根据实际情况对射流喷嘴的大小进行调节。
上述技术方案的改进是：所述射流液体进口管的口径大于进气管的口径。
上述技术方案的改进是：位于所述进气管处的一段射流喷嘴呈扩张锥形。
上述技术方案的改进是：位于所述进气管处的一段射流喷嘴处设有螺旋叶片，所述螺旋叶片的螺旋升角为20°。
本发明采用上述技术方案的有益效果是：通过螺旋叶片对射流喷嘴出口处流体进行螺旋加速，可以对左、右夹板之间形成的射流喷嘴内流体进行加速，实现对进气管内气体进行更高效率的抽吸。
上述技术方案的改进是：所述进气管垂直右夹板设置。
上述技术方案的改进是：所述进气管倾斜右夹板设置。
