Pneumatic liquid outlet device of settling tank

The utility model discloses a pneumatic liquid outlet device of a settling tank, and relates to the field of precipitation separation equipment after solid-liquid mixing and stirring. The liquid outlet device comprises a liquid outlet pipe and a telescopic mechanism, the telescopic mechanism drives the liquid outlet pipe to ascend and descend, and the upper end of the liquid outlet pipe is externally connected with a vacuum system, so that supernate in the tank can be conveniently sucked out from the upper part without stirring sediments at the lower part of the tank. The device replaces a common floating ball hose type liquid outlet device, and is easier to clean and more convenient to discharge. 本实用新型公开了一种沉淀罐气动出液装置，涉及固液混合搅拌后沉淀分离设备领域。该出液装置包括出液管和伸缩机构，通过伸缩机构带动出液管的升降，在出液管上端外接真空系统，即可方便将罐内上清液从上部吸出，而不搅动罐下部沉淀物。该装置替换了常用的浮球软管式出液装置，清洗更容易，出料更方便。
