The invention discloses an automatic drain box, wherein, the inner cavity of the box body is divided into a water inlet area and a water outlet area, a water inlet is arranged in the water inlet area, and a water outlet with a sealing cover is arranged in the water outlet area, and the sealing cover is connected with the floating ball. The hydrophobic box type instead of the current power plant commonly used single stage and multi-stage water sealing pipe, the hydrophobic box adopts partition partition, the automatic float water level control, automatic closing water outlet; the volume is smaller, greatly reducing the water pipe construction difficulty and engineering quantity, at the same time can prevent the occurrence of water is evacuated or drain Chang, to improve the safety of drainage system, and has no special requirements on the layout, optimizing the layout of this region to provide more favorable conditions to solve the traditional U type water sealing pipe construction difficulties, the effect is not good and difficult to seal maintenance problems. The utility model has the advantages of simple structure, compact arrangement, simple construction and maintenance, small occupation area, convenient construction, safe and reliable operation, strong practicability and wide applicability.

一种自动疏水箱
本专利技术涉及一种疏水箱,具体涉及一种自动疏水箱。
技术介绍
火力发电厂的轴封加热器为管壳式换热器,壳侧接受汽机轴封系统漏汽,经管侧冷却、冷凝后疏水回收至凝汽器。凝汽器正常运行时为真空,为避免疏水被抽空,影响凝汽器运行真空,疏水一般采用U型水封管,以水柱高度封住蒸汽和空气联通通道。目前电厂常用的水封管型式有单级水封和多级水封。单级水封和多级水封在电厂运行中普遍存在一些问题,单级水封由于水封高度不够或介质汽化的原因,易造成水封被抽空,前端蒸汽直接冲入凝汽器,影响主机真空度;多级水封由若干单级水封串接组成,由于杂质或计算高度影响,易造成疏水不畅。单级和多级水封的构造体积较大,建造时耗材较多,施工复杂,且需要占用较大的空间,若埋于地底,易受周围基础施工影响,造成水封管弯曲变形,同时也容易有杂物掉入其中,在杂质进入水封管后,积留在U型管道中,难以检查和去除,长时间运行后造成通流面积减小,疏水不畅,影响水封管的正常运行。
技术实现思路
为解决现有技术的不足,本专利技术的目的在于提供一种尺寸小,施工简单,运行安全可靠的自动疏水箱。为了实现上述目标,本专利技术采用如下的技术方案:一种自动疏水箱,隔板将箱体内腔分隔为进水区和出水区,所述进水区设有进水口,出水区设有带封盖的出水口;所述封盖连接浮球。上述进水区和出水区于隔板顶部连通。上述封盖通过弹簧封堵出水口,使得在浮球拉力不足,或无浮球拉力状态下,封盖通过弹簧封堵出水口。上述出水口的高度低于隔板的顶部高度。上述浮球的工作高度低于隔板的顶部高度。上述进水区和出水区底部分别设有排污口,通过排污口清除长时间积留的水淤 ...
